General Safety and Security Essay

* Investment in surveillance camera systems by school districts ensures parents and guardians that the general safety and security of children are being addressed during schools hours and at all after-school extracurricular activities and programs. 2. Crime Deterrent * The presence of highly visible surveillance cameras at strategic locations in buildings and public areas/premises of a school property prevents theft, vandalism and acts as a deterrent to thieves and criminals from indulging in illegal activities. 3. Sexual Predators * One of the biggest threats that school children face is the threat of sexual predators and pedophiles hanging around unobtrusively on school campuses or in parking lots. Camera systems’ footage is very useful in tracking down predators or helping inform police about threatening situations in real time. 4. Prevent Bullying * New-generation surveillance camera systems have audio, voice and sound capturing capabilities. Teenagers bullying or harassing other students can be disciplined based on video and audio footage records. 5. Emergency Evacuation * School security personnel manning surveillance camera systems in real-time can take quick action about evacuating children, faculty and staff in case of emergencies related to fire or other potentially dangerous situations. Prevent Theft and Illegal Activities * The primary purpose of installing surveillance cameras is to act as deterrence to robbers, criminals, petty thieves and unscrupulous elements from indulging in theft, illicit and criminal activities. Security cameras are installed in bungalows, townhouses, apartment buildings, condominiums, schools, university campuses, offices, stores, malls and other public areas. These cameras monitor suspicious activities; stop theft, vandalism and shoplifting; and alert stationed security officers about real-time thefts. Staff monitoring cameras and centrally manned systems in large businesses can also inform county and state law enforcement officials about developing dangerous situations.

Globalization and Early America, 1492-1750

America’s present is significantly shaped by its past. Hence, it is vital for one to grasp the concepts that formed America to what it is now. Globalization in America is one of the key notions that play a vital role in forming today’s society. Though several scholars place the origins of globalization in modern times, others trace its history long before the European age of discovery and voyages to the New World. However, did early American history play a role in creating today’s globalization? Does globalization in the past play a positive, or negative role in this time period? While some might argue that weakening national autonomy is a negative result of globalization, others might defend that it has also sparked economic innovation. One of the major characters that changed the history of the world was Christopher Columbus. What would be the outcome today if Columbus never discovered the New World? Firstly, colonization would be nonexistent. In addition, without colonization U. S. ould have never created. The creation of the U. S. helped move much of the world towards democracy. It also led to the development of what is now the world's only superpower. A world without the United States is impossible to imagine today. Furthermore, a discovery by another major character, Ferdinand Magellan, also had a tremendous impact on the history of the world. He proved that oceans connected continents rather than dividing them. How did this important discovery influence today’s economy? By having the knowledge that oceans were great global passageways, Magellan had demonstrated that continents could be linked. Europe had the opportunity to establish a great economy and military power over Asian, Africa and the Americas that created great global trade networks. This was the beginning of the creation of globalization, which is very significant for today’s world economy. This also further demonstrates that early American history did play a role in creating today’s globalization.

Gambling Essay Example | Topics and Well Written Essays - 500 words - 1

Gambling - Essay Example Regardless of the consciousness, the practice involves some form of potential gain to the involved parties. Gambling defines a game or a bet with uncertain result that aims at deriving a benefit. It involves parties that make a bet over an unpredictable outcome, at a sacrifice, and the person who is favored by the game’s outcome benefits from the sacrifices at the expense of the other parties (Johnson, 2011). The first element of gambling is therefore existence of a game whose results are not known at the time of the parties’ entry into the gamble. The game either may involve the parties or may be independent in such a way that the parties are just but observers. An example of a game that involves the parties is a dice throwing game by the parties with a defined outcome as a win. The parties may also engage in a sport in which the winner of the sports becomes the winner of the gamble. Alternatively, it may involve a game that is being played by different parties. An example is a competitive football match or tournament such the United States premier league or a game in the premier league. In either of the cases, the result of the game that determines the winner and the looser in the gamble is uncertain at the time the parties enters into the gamble and is determinate later (Johnson, 2011). Another essential element that defines a gamble is the associated reward that it involves. This is because its basis involves a bet in which a party relinquishes rights over a property. The property is then put under custody with its possession determined by the outcome of the subject game. If the results favor a party’s position in the gamble then he or she becomes the owner of the property that was put on the particular gamble. Any other party who is not favored by the results of the game therefore loses their property in the game. This is the general rule of gambling that depends on lack to benefit a party based on taken chances (Johnson,

Rises of Interest Rate is Affecting the Housing Affordability Essay

Rises of Interest Rate is Affecting the Housing Affordability - Essay Example As the interest rates rise, the mortgage payments amounts also escalate. This poses as an unfavourable situation for the homebuyers, and causes a decline in the housing affordability. Empirical evidence suggests that this has been the case in the years whenever the interest rates rose. When such is the situation, the homebuyers can be offered such financial products by the banking sector that they can conveniently make the home buying decision, thus supporting the housing affordability. The huge majority of Australians desire to own a home and housing assets form the leading fraction of wealth for a good number of Australians. Australian house prices have been mounting discordantly in recent times. This price growth has been well in surplus of average weekly earnings growth over the same period, and as such the ratio of house prices to average earnings is now soaring. The Australian property market is basically comprised of many markets of separate sectors and geographical locations. This is the fact that must be considered as many various forces may contribute in shifting prices in separate markets, and the overall Australian property market's price gains or falls may disguise the actual micro market price shifts. Residential housing is determined by two markedly separate sources of demand; owner-occupiers and owner-investors. Both sources of demand are determined by diverse (but connected) aspects and the payback that accrues to the owner can take a collection of shapes depending on their standing. Payback can be the accredited rent that owner-occupiers get hold of by living in a house, or it can be the takings resulting from renting out an investment property or it can be (in both cases) the capital gain that is realised upon selling of the hothirty percent of income. The level of nominal interest rates and their rate of change are major determinants of the demand for home finance, along with levels of consumer confidence. (http://www.dhw.wa.gov.au/housingstrategywa/hswa_finance.pdf) Affordability of access and servicing of payments becomes an increasing issue as interest rates rise. Any rise in interest rates is probable to upset borrowers with diminutive equity and make it further difficult for would-be first homebuyers. Simply speaking, housing finance is the system of money and credit that works to offer housing affordability. In that sense, it is quite similar to finance for any other shape of investment. The established level of interest rate also affects the demand for and supply of home finance. The customary economic conditions very much affect the interest rates, over which the housing sector has very little control. Research Questions Aims and Purpose This research paper will aim to provide an insight to the effect of a rise in interest rates on the housing affordability of Australia. The close link of these two aspects, that is the interest rate levels and the housing affordability will be proved and the various other driving forces will be identified. The historical data and figures will be used to establish the empirical trend. In addition, why such a link exists and what are the reasons that the housing affordability is connected to the prevailing levels of interest rates will be illustrated in this paper. Objectives This

Psychology - Essay Example Learning can broadly be defined as ‘relatively permanent change in behaviour’ (Burns, R., 2002) through observable activities and internal processes of perception. The comparative perspective of psychology of learning primarily relies on the observation of behavioural activities of others that prompt others to improve and improvise one’s actions to optimize the performance outcome. When the observations provoke some mental processing to come to some inference, the approach is defined as cognitive approach. Thus, the varying reactions of the observations and behavioural pattern due to external objects give rise to theories to explain learning processes. The two major psychological approaches of learning are behaviourism and cognitive approach which would be compared to understand the wider implications of the approaches that are used at various levels of interaction. Theory of Behaviourism asserts that the one sees and experiences the world in its physical entirety and one responds as per the law of the nature which is constant for everyone. The principles of natural laws are based on cause and effect. Grippin and Peters claimed that this approach focuses on three vital ingredients of behaviour: observation of behaviour; environmental paradigms that influence the behaviour; and the principles of continuity and reinforcement that facilitate learning process (Grippin & Peters, 1984). Cognitive approach is basically an amalgamation of philosophical thoughts and scientific theories that try to rationalize the working of conscious and unconscious thoughts of a man and co-relate them with his subsequent actions and reactions. The theory of cognition, thereby, tries to explain why and how the events take place and subsequent pattern of behaviour of man under certain condition involving emotional and metaphysical reaction. The role of brain and conscious and unconscious activities of the mind are seen to be the responsible for the

Questions - Essay Example The executive branch is conferred â€Å"with exemptions and qualifications† in the President of the United States; he also has the power to veto laws (Davis 1). The president is not obliged to enforce the law; instead, the president’s minions should perform these duties. Lastly, the judicial branch of the government has the authority to decide over cases and disputes. This power is conferred to the Supreme Court and lower courts as recognized by the Congress. Each branch of the United States national government possesses powers that it can utilize to check and balance the functions and activities of the other two branches. Declaring George Washington’s greatest achievement would always be subjective and indefinite in nature; but, in all probability, he desisted from taking more power than what was appropriate (Wood 105). After his resignation as the Commander-in-Chief of the continental Army, the people wanted him to become the King of the newly-formed nation; nevertheless, he refused to accept this fate, and instead, he wanted to have a democratic and free country. He was thorough of upholding a good standing by precluding political conspiracy. He showed no attention and notice over partiality and cronyism. Perhaps his greatest failure was when he approved the passing of The Fugitive Slave Act of 1793, which provided slaveholders the right to regain their property; also, to help a runaway slave is a grave crime, which eventually permitted the proliferation of slave chasers within the United States’ territories. This is a rather subtle move to sustain slavery, which is contradictory to his desire to create a democratic and free country. On the whole, Washington’s administration led the successful emancipation of the slaves, which although hampered in his initial decision to implement The Fugitive Slave Act of 1793, eventually

Social Aspects of Down Syndrome Research Paper Example | Topics and Well Written Essays - 1250 words

Social Aspects of Down Syndrome - Research Paper Example This is a curable disease that if identified in the early stages after birth can be managed properly to later stages in life. The different aspects for children and adults, speech, relationships with groups and how certain environments influence social skills and mental capabilities are vital signs to be considered critically (Royston 2005). This includes the developments of friendships, interpersonal social skills, leisure and play skills, self-help skills and independence and socially recommended behavior. Social skills for being independent, making friends, searching work and becoming independent through social confidence and competence is vital than academic skills. The ability to understand others feelings, emotions, and their behavior lead to success in social relations. For both children and adults suffering from Down syndrome, social understanding starting in infancy is considered as strength. The none verbal cues like voice tonal variation, facial expressions, posture and gestures indicate how someone feels, that in the event when one does not understand the spoken words used, they are suppose to pick the major messages about feelings and thus behave appropriately. Children and adults with strong social skills and empathy suffering from Down syndrome tend to enjoy better social behavior and understanding than t heir counter parts with the same stage of communication delays. On the other hand, this understanding of others behavior also enables Down syndrome children to be naughty since they have knowledge of how to provoke the reactions of the others (Evans 2009). The social development of infants with Down syndrome is influenced by their experiences in the environment by factors like family, society and schools, their tempers and the treatment they receive from others. Different behaviors in children are experienced according to their immediate environments, for instance, where a child notices negative emotions

Assignment Example This scenario may, however, fail to materialize. One of the factors that may lead to the failure of this mechanism is loss of fluorescence. The exact origin of signal loss has not been established, but tentative explanations have been given. A mechanism that could explain this is the slow degradation of surface ligands and coatings, when they are in body fluids (Gao, Cui and Levenson). This issue may be resolved by continuous laser excitation which corrects the surface defects. The process of imaging using CdSe quantum dots capped with ZnS may also fail due to the light type used during imaging. The orange/red emitting QDs used are not optimized for tissue penetration. The QDs are also not optimized for imaging sensitivity. The mechanism associated with failure in this manner is the lack of capability of deep tissue imaging by this kind of light. To prevent failure in this manner, it is advisable to use far-red and near-infrared light. This light should be in the spectral range of 650-900 nm. This wavelength is separated from the absorbing peaks of water and blood. For this reason, the tumor imaging sensitivity will be improved y at least tenfold (Gao, Cui and Levenson). Another factor that may cause the failure of this process is the toxic nature of CdSe QDs under extended periods of illumination by UV radiation. Radiation by UV dissolves the semiconductor particles causing the release of cadmium ions into the medium. Cadmium ions are toxic in nature. This may be avoided by the use of QDs with a stable polymer protection layer (Gao, Cui and Levenson). The stably protected QDs are non-toxic to cells; they affect neither cell division, nor ATP production. Certain issues have to be addressed for the CdSe quantum dot-based cancer imaging to be successful. The researcher has to ask questions that include: Is the mode of imaging economically viable basing on the

Consumer Health Information - Coursework Example A major advantage of using the internet is its relative cheapness that allows many people to access information about their health and other medical issues they would like to know about without having to pay the high consultation fees that are charged by many doctors and other specialists. Conversely, a major disadvantage of using the internet to search for medical information pertains to the credibility of some of the web pages. This is because some of the web pages are created by people without the appropriate amount of knowledge in the topic they discuss in those web pages. The use of the internet provides empowerment to the users as they are able to get information pertaining to various health issues they seek to know quickly and cheaply. This saves them both time and money and enables them to make various decisions that better their lives. This paper provides valuable information pertaining to the use of the internet to search for medical information as well as a major advantage and disadvantage of using the internet. As noted, the internet is indeed a cheap and quick source of complex health and medical information. The disadvantage is the aspect of believing any information on the internet as it might be false. This is very important to note and users should be informed to be cautious of the information that they fond on the internet. This information relates to the course concepts and provides a basis for understanding the rise of the internet as a viable source of medical information to users. Healthcare organizations provide very important services to the patients that get treatment and other health services provided by these organizations. It is therefore very important to ensure that these organizations have effective management systems and strategies.  

Girl Postitive Essay Example for Free

Girl Postitive Essay The movie â€Å"Girl Positive† is about, Rachel, a teenage girl Rachel in high school that has come in contact with the disease HIV. The movie shows how people in her high school view the disease. They also stereotype it, saying only gay people can get. They are quickly proven wrong though. A recent report put up on the school website shows that the star athlete that graduated before them was doing heroin. He had just died in a car accident and they found it in his system and in his car. Everybody was completely shocked. After the report came out Rachel received a message that told her that this star athlete, Jason, had HIV. They were concerned about her well-being and asked if she also had the disease because she had lost her virginity to him at a party. Rachel became close with a new teacher at the school who conveniently worked at an AIDS clinic too. She asked to do some community service down there for extra credit. While Rachel was there she snuck a HIV test and took it. Later on, the results came back positive and the teacher was trying to help her out but Rachel didn’t want to listen. She was scared and didn’t want anyone to know. Rachel tried telling her boyfriend, but he didn’t understand. The rumors started in her school about her having it and her life felt like it was falling apart. But then Mark, Jason’s brother, came to Rachel with a video admitting that Jason was HIV positive. They decided the school needed to know. When they all found out, almost the entire senior class went to this AIDS clinic and were getting tested. Rachel and her mom stood by each other’s side and got blood test done to know for sure. The movie ended with the doctor saying she was positive; which I think was a really disappointing ending. I thought this movie was really good. It shows that people really do not know about this awful disease. They think it will kill them instantly, but really won’t if they take the right meds. I also think it’s very insightful. Although a lot of the scenes in the school were off because personally that wasn’t like my school at all. I think this is a really good movie to shows because it gives a lot of facts on HIV that I didn’t know and I’m sure many other teenagers don’t know either.

Fluid Catalytic Cracking Process Engineering Essay

Fluid Catalytic Cracking Process Engineering Essay INTRODUCTION Fluid catalytic cracking process, which is now more than 60 years old, is the cornerstone of most of the petroleum refineries. It has proven to be the most-efficient process available for the conversion of gas oils and residue into more valuable lighter hydrocarbons. Many refiners consider the catalytic cracking process to be the highest profit generating unit in the entire refinery. In earlier times, Fluid Catalytic Cracking Unit (FCCU) was operated broadly in two modes, they are; Maximum gasoline mode Maximum distillate mode But with the advent of Reformulated gasoline (RFG), these are now operated in maximum olefin mode. FCCU is a very sophisticated unit with many factors affecting each other and the overall process. In some processes investigation of factors impact is done by changing one factor at a time while keeping other factors constant. In case of FCCU it is almost practically impossible to obtain a clear indication; as, change in one single factor leads to change(s) in one or more other factors. This whole phenomenon is a natural consequence of the heat balance of FCCU. If the unit is to operate at steady state, then the unit has to be in heat balance condition. At this stage the heat requirement in the reactor is satisfied by burning coke in the regenerator and transferring the energy to the reactor through circulating hot catalyst. Heat balance around the reactor-regenerator can be used to predict the effects of process changes although the exact degree of the changes may be difficult to estab lish. It is one step at a time thought process and rather difficult to pin down exact numbers without a careful study of yields and coke laydown rates as affected by changing variables. In this work a plant data is taken as reference and based on that, calculations have been done to find out the net heat of endothermic reactions occurring in the riser reactor, assuming that the unit is operating at steady state and that the riser is an isothermal one. Then as per the products slate, a 7-lumped model is considered from various literatures and based on the kinetics of reactions, rate equations are formed and with the knowledge of available kinetic parameters the differential temperature drops along the height of the riser are calculated. PROCESS DESCRIPTION More than a dozen types of FCCU are operating worldwide. But the basic designs of all these type remain the same. FCCU comprises of two parts; Riser reactor, in which catalytic cracking reactions occur Regenerator, in which burning of coke (deposited during cracking) from the catalytic sites is done Figure 1 shows a schematic diagram of a typical FCCU. The feed is preheated in a furnace and (Figure: 1- Schematic Diagram of a typical FCCU) injected at the bottom of the riser along with a small amount of steam. This steam helps in dispersion of feed, good atomization and reduces coke formation by decreasing the partial pressure of hydrocarbon vapours. The feed is subsequently vaporized when it comes in contact with the hot catalyst from regenerator. The hydrocarbon vapours so formed undergo endothermic cracking reactions on their way up through the riser. The expansion of product vapours occurs through the length of the riser and the gas velocity increases with decreasing gas density. Hot catalyst particles provide the sensible heat and latent heat requirements for vaporizing the liquid feed and also endothermic heat of reaction for the cracking reactions. After a certain distance from the entry zone of the riser, the liquid feed is completely vaporized. Cracking reactions continue with the vapours moving up in the riser and the temperature is dropped along the length of the riser due to endothermic nature of cracking. The catalytic cracking is started and also completed in a very short period of time inside the riser reactor in which the catalyst is pushed upward by incorporating steam at various locations along the length of the riser and hydrocarbon vapours. Mixture of catalyst and hydrocarbon vapour travels up in the riser into the reactors. Steams injected at different locations in the riser are as follows, Fluffing steam at the bottom of the riser Dispersion steam along with fresh feed injectors Riser dilution steam above the fresh feed injectors Dispersion steam along with recycle stream injectors Aeration steam into the riser J bend to fluidize the catalyst Along with this some other locations are there where steam is injected. They are as follows; Spent catalyst standpipe aeration steam Regenerated catalyst standpipe aeration steam Reactor quench steam Reactor dome steam Post riser quench steam Stripping steam into strippers Mixture of catalyst and hydrocarbon vapour is discharged from the riser to the riser cyclone assembly. The bulk of the spent catalyst is separated from product vapours in the cyclone assembly. If necessary the vapours leaving the riser cyclones are routed into secondary cyclone assembly located inside the reactor vessel. Separated catalysts flow through each cyclone dip leg into the stripper. Product vapours leave the reactor cyclones and flow into the main fractionator through the reactor overhead vapour line. Quench steam is injected inside the reactor vessel to reduce the temperature, so as to minimize post riser thermal cracking reactions and coke formation. Reactor dome steam is provided to sweep hydrocarbons and avoid dead areas on top of the reactor vessel that may lead to thermal cracking and coking in that area. The separated catalyst from the riser and reactor cyclone assemblies enters the catalyst stripper. As the catalyst flows down the stripper, it gets stripped off the entrained hydrocarbon vapours by the up flowing steam. Stripping enhances the product recovery and reduces the carryover of hydrocarbon to the regenerator along with the spent catalyst thereof. Fluffing steam ensures the fluidization of the circulating catalyst. Stripped catalyst from the stripper flows into the regenerator dense bed through the spent catalyst standpipe (SCSP). Catalyst level in the stripper is maintained by spent catalyst slide valve (SCSV). Aeration steam is provided in the SCSP to ensure proper flow and fluidization of spent catalyst. Coke adsorbed on the spent catalyst during cracking reaction is been removed in the regenerator by burning off the coke with air. Air is supplied from the air blower to the regenerator through multiple distributors. Air is also introduced at different locations of the regenerator, they are as follows; T-grid air Regenerated catalyst standpipe (RCSP) hopper aeration air RCSP aeration air Regenerator fluffing air at the bottom near the J bend The regenerator can be operated in two modes; Partial combustion mode Complete combustion mode For partial combustion mode, a CO boiler is needed to convert CO to CO2. The current discussion is for complete combustion mode regenerator. Flue gas from the regenerated dense bed flows to the two stage regenerator cyclone assembly. Here the entrained catalyst is separated from the flue gas. The separated catalyst flows back to the dense bed through cyclone dip legs. Flue gas from the cyclone flows out from top of the regenerator through a flue gas line. Total air flow to the regenerator is regulated based on the desired level of oxygen in flue gas. Too low O2 concentration will cause coke build up on regenerated catalyst and CO release from regenerator. Too high O2 concentration will lead to regenerator cooling. So, regenerator flue gas is regularly examined for O2, CO, CO2, NO2, SO2 analysis. FEED CHARACTERIZATION The only constant in FCC operation is the frequent change in feedstock quality. Thats why two feeds with similar boiling point ranges can exhibit huge differences in cracking performance and product yields. Feed characterization is one of the most important activities in monitoring the FCC process. Feed characterization is the process of determining physical and chemical properties of the feed. Understanding feed properties and also knowing their impact on units performance is an essential thing. Trouble shooting, catalyst selection, unit optimization and subsequent process evaluation, all depend on feedstock. Feed characterization relates product yields and qualities to feed quality. Analytical techniques like mass spectrometry are sophisticated and not practical for determining complete composition of FCC feedstock. Simpler empirical correlations are often used. They are as follows; oAPI gravity and UOP K Boiling range Average boiling point Carbon residue Metals Sulphur, Nitrogen and Oxygen oAPI gravity and UOP K It is a specific gravity relating the density of oil to the density of water. The empirical formula for this is; oAPI 131.5 (3.1) Feed to an FCC can range from 15o to 45o API. If the API gravity increases the charge stock will crack more readily and for the same reaction temperature there will be greater conversion. Secondly at a constant conversion level, there will be greater gasoline yield with slightly lower octane. A rough indication of the quantities of paraffin present is a characterization factor which relates boiling point to specific gravity, is called the UOP K factor. This is given by; (3.2) Where: CABP = cubic average boiling point, oR SG = specific gravity at 60 oF Higher the UOP K value more is the paraffinic nature of the feedstock. Boiling Range The boiling range of FCC feed varies from an initial point of 500oF to an endpoint of about 1000oF. There are two boiling point ranges which are used to describe the lighter material in the feed. They are; Per cent over 430oF Per cent over 650oF The first quantifies the amount of gasoline in the feed. The second one quantifies the light fuel oil in the charge. Average boiling point Average boiling point of the FCC feed depends on the average molecular weight. An increase in average boiling point and molecular weight will typically cause the following; The charge will crack more readily, so at constant reactor temperature conversion will increase At constant conversion, yield of C4 and lighter will decrease Olefinic content of the product will decrease Regenerator temperature will tend to rise At constant conversion, the gasoline yield will increase about 1% for an increase in the molecular weight of 20. Carbon residue The carbon residue of a feedstock is an indirect measure of its coke producing nature. Values may be determined by either Conradson or Ramsbottom methods. The carbon residue can be a useful number for determining possible contamination in storage. Entrainment in vacuum tower is a common cause of increased carbon residue. Colour may be used to approximately evaluate the carbon content of the feedstock. Darker stocks tend to have higher carbon residues. Metals Organometallic compounds in the FCC feed can cause serious overcracking if the metals deposit on the catalyst. The cleanliness of a chargestock is given by a metals factor: Fm = Fe + V + 10 (Ni + Cu) (3.3) Where: Fm = Metals Factor Fe = Iron concentration V = Vanadium concentration Ni = Nickel concentration Cu = Copper concentration All metal concentrations are ppm by weight in the feed. A factor of 1.0 is considered safe, over 3.0 indicate a danger of poisoning of catalyst. Sulfur, Nitrogen, Oxygen Sulfur is as undesirable in FCC feed as it is in the feed to most of the refining units, causing corrosion of the equipment and increased difficulty in treating products. At 50% conversion about 35% sulfur charged is converted to H2S, and at 70% conversion the figure will rise to 50%. Nitrogen produces NH3 and CN- in the reactors, and NOx and trace quantities of NH3 in the regenerator. These NH3 and CN- cause plugging and corrosion, while the NOx and NH3 in the flue gas cause environmental problems. Gas oil will absorb oxygen in storage unless the tanks are gas blanketed. This oxygen will combine with the compounds in the oil at about 450oF to form gum, which fouls heat exchangers. FCC REACTION CHEMISTRY Cracking reactions are predominantly catalytic, but some non-selective thermal cracking reactions do take place. The two processes proceed via different chemistry. The occurrence of both the reactions is confirmed by distribution of products. Catalytic cracking proceeds mainly via carbenium ion intermediates. There are three dominant reactions in cracking are catalytic cracking, isomerization, hydrogen transfer. The idealized reaction classes are tabled below with specific reactions to support them. (Table: 1 idealized reactions of importance in FCCU) Reaction classes Specific reactions Cracking n-C10H22 n-C7H16 + C3H6 ; 1-C8H16 2C4H8 Hydrogen transfer 4C6H12 3C6H14 + C6H6 ; cyclo-C6H12 + 3 1-C5H10 3n-C5H12 + C6H6 Isomerization 1-C4H8 trans-2-C4H8 ; n-C6H10 iso-C4H10 ; o-C6H4(CH3)2 m- C6H4(CH3)2 Transalkylation C6H6 + m- C6H4(CH3)2 2C6H5CH3 Cyclization 1-C7H14 CH3-cyclo-C6H11 Dealkylation Iso-C3H7-C6H5 C6H6 + C3H6 Dehydrogenation n-C6H14 1-C6H12 + H2 Polymerization 3C2H4 1-C6H12 Paraffin alkylation 1-C4H8 + iso-C4H10 iso-C8H18 Some of the reactions are endothermic in nature and some are exothermic in nature. Each reaction has a heat of reaction associated with it. The overall heat of reaction is the combination of both the types of heat of reactions. Though there are a number of exothermic reactions, then also the net reaction is endothermic. It is apparent that the type and magnitude of reactions have an impact on the heat balance of the unit. If the catalyst is with less hydrogen transfer characteristics, it will cause the net heat of reaction to be more endothermic. This in turn results in higher catalyst circulation and possibly a higher coke yield to maintain the heat balance. FCC UNIT MATERIAL BALANCE For this, a complete set of commercial plant data is used.

All the gas calculations are based upon 100 moles of flue gas. The oxygen consumed for H2O is given by the expression; O2 consumed = * (vol. % of N2 in flue gas) 2 * (vol. % of O2 in flue gas) 2 * (vol. % of CO2 in flue gas) (vol. % of CO in flue gas) (5.1) So, O2 consumed = * (81.83) 2 * (2.49) 2 * (15.58) (0.005) = 7.36 The weight of the hydrogen and carbon in the coke are calculated; Weight = 2.016 * (7.36) + 12.01 * (15.58+0.005) = 202.01 The temperature differentials are calculated; (oF basis) ΆTRR = (Regenerator dense bed temperature Riser outlet temperature) (5.2) = 1184 1004 ΆTRR = 180 ΆTRB = (Regenerator fluegas temperature Blower discharge temperature) (5.3) = 1215 439 ΆTRB = 776 ΆTRS = (Riser outlet temperature Stripping steam temperature) (5.4) = 1004 554 ΆTRS = 450 The weight combined feed ratio is calculated as; (Flow rate)CLO * (Density)CLO * 2.204 CFR = (5.5) (Flow rate)Fresh feed * (density)fresh feed * 2.204 = CFR = 0.074 The stripping steam and inert gases carried to the reactor by the regenerated catalyst are calculated on a weight per pound fresh feed basis; Steam = (5.6) Steam = 0.01 Inert gases = (5.7) Inert gases = 0.007 The amount of hydrogen in the coke is calculated as; Hydrogen in Coke, wt % = [2.016 * 7.36 / 202.01] * 100 % = 7.35 wt. % The air to coke ratio is; Air to coke, wt/wt = (2897/202.01) * (81.83/79) Air to coke, wt/wt = 14.85 lbs air / lb coke Where; 2897 is the molecular weight of air multiplied by 100 (basis of 100 moles of flue gas) The weight of coke per hour may be calculated as; Weight of coke, lbs/hr. = (4591) * 193.23 / 14.85 = 59738.6 lbs/hr. Where; (310717 Nm3/hr. = 5178.62 Nm3/min. = 193.23 MSCFM 4591 = air rate conversion factor from MSCFM to lbs/hr.) So, weight % of coke is then; wt. % coke = * 100% = (59738.6 / 1104941.7) * 100 % wt. % coke = 5.41 In the product yield table, the coke wt. % is indicted as 5.01 wt%. But it is calculated as 5.41 wt. %. Now the overall weight balance is as follows; OVERALL WEIGHT BALANCE INPUT:- = Fresh feed + Coker naphtha + CLO recycle = {(533.4 * 0.8 * 894 * 2.204) + (533.4 * 0.2 * 932 * 2.204)} + (30.2 * 676.2 * 2.204) + (46 * 808 * 2.204) = 1186860.1 lbs. / hr. OUTPUT:- = Total product yields + coke = 1149831 + 59738.6 = 1209569.6 lbs. / hr. So, error in weight balance is calculated as; = INPUT OUTPUT = (1186860.1 1209596.6) lbs. / hr. = 22736.5 lbs. / hr. = 1.88 wt. % = 98.12 % closure Now combustion heat of coke is determined as follows; (at hottest temperature = flue gas temperature = 1215oF) ΆHcomb = [(X) (vol. % of CO in flue gas) + (Y) (vol. % of CO2 in flue gas) + (Z) (vol. % of O2 consumed)] / (weight if hydrogen and carbon in coke) (5.8) = [(48000) * (0.005) + (169743) * (15.58) + (106472) * (7.36)] / 202.01 ΆHcomb = 16971.8 Btu / lb coke Where; X = heat of combustion of CO at 1215oF Y = heat of combustion of CO2 at 1215oF Z = heat of combustion of H2O at 1215oF There is correction factor for the hydrogen in coke, this is given as; Correction factor, C = 1133 (134.6) (wt. % hydrogen) (5.9) = 1133 (134.6) (7.35) = 143.7 The net heat of combustion after using the correction factor is; -ΆHC = 16971.8 + 143.7 Btu / lb coke -ΆHC = 17115.5 Btu / lb coke At this point the reactor and regenerator heat balances are calculated. The catalyst supplies the heat to the reactor. The regenerator heat balance is calculated first using a basis of one pound of coke at the hottest regenerator temperature. The reactor heat balance is based on one pound of fresh feed. HEAT BALANCE REGENERATOR HEAT (Figure: 2- Regenerator heat In Out scheme) HEATREG = ΆHCOMB. ΆHCOKE ΆHAIR ΆHRADIATION LOSS (6.1) Now, ΆHCOKE = heat required to raise coke to combustion temperature = (0.4) * (ΆTRR) (6.2) ΆHAIR = heat required to raise air to combustion temperature = (lb air / lb coke) * (0.26) * (ΆTRB) (6.3) ΆHRADIATION LOSS = 250 Btu / lb coke So, HEATREG = 17115.5 {(0.4) * (180)} {(14.85) * (0.26) * (776)} 250 HEATREGHEATREG = 13797.4 Btu / lb coke -ΆHCSo, regenerator efficiency = *100% (6.4) = 80.6 REACTOR HEAT (Figure: 3- Reactor heat In Out scheme) HEATRX = ΆHFRESH FEED + ΆHRECYCLE + ΆHSTRIPPING STEAM + ΆHREACTION + ΆHRADIATION LOSS + ΆHINERTS (6.5) ΆHFRESH FEED, ΆHRECYCLE = heat required to raise fresh feed recycle to reactor temperature ΆHSTRIPPING STEAM = heat required to raise steam to reactor temperature = ΆTRS * (0.485) * (lb steam / lb fresh feed) (6.6) ΆHRADIATION LOSS = 2 Btu / lb fresh feed ΆHINERTS = heat of inert gases carried from regenerator to reactor by regenerated catalyst = ΆTRR * (-0.275) * (lb inerts / lb fresh feed) (6.7) HEATRX = (enthalpy of fresh feed at riser outlet temperature enthalpy of fresh feed at preheat temperature) + CFR (enthalpy of recycle feed at riser outlet temperature enthalpy of recycle feed) + ΆTRS * (0.485) * (lb steam / lb fresh feed) + 2 Btu / lb fresh feed + ΆTRR * (-0.275) * (lb inerts / lb fresh feed) + ΆHREACTION = (745 460) + 0.074 * (745 460) + 450 * (0.485) * 0.01 + 2 + 180 * (-0.275) * 0.007 + ΆHREACTION HEATRX = 310 + ΆHREACTION Note:- Enthalpies for the fresh feed and the recycle feed were calculated by taking respective UOP K values, oAPIs and the temperatures from the API technical data book. Regenerator heat is calculated on a one lb of coke basis. This can be converted to one lb of fresh feed by use of weight % of coke term. So, HEATRX = HEATREG () (6.8) ΆHREACTION + HEATRX = HEATREG () + ΆHREACTION (6.9) ΆHREACTION = HEATREG () + ΆHREACTION + HEATRX (6.10) But HEATRX = + ΆHREACTION Putting this relation in equation (6.10), the equation changes to ΆHREACTION = HEATREG () ΆHREACTION = 13797.4 * 310 ΆHREACTION = 436.44 Btu / lb fresh feed So, HEATRX = 310 + 436.44 HEATRX = 746.44 Btu / lb fresh feed (0.275) (ΆTRR)Cat / Oil (wt. / wt.) = HEATRX (6.11) Cat / Oil (wt. / wt.) = 15 lb Catalyst / lb Oil Catalyst circulation rate = (Cat / Oil) * (lb fresh feed / hr.) (6.12) = 15 * 1104941.8 CCR = 16574127 lbs. / hr. = 7524 MT/ hr. Overall heat flow scheme for the whole FCCU can be shown as below; (Figure: 4- Typical FCCU heat balance scheme) Now, the net total endothermic heat of reaction is calculated through empirical formulae. But we took the assumption as the riser is an isothermal one. Practically it is not isothermal. The temperature at the base of the riser is higher than what is at the top of the riser or at the riser outlet. This is because the cracking reactions occurring along the length of the riser is endothermic in nature. So heat is being absorbed during the reaction and causes the temperature at that particular location to decrease. Gradually the temperature decreases and at the riser outlet the temperature is dropped significantly. In this context we can estimate the riser base temperature using empirical relations and therefore can estimate the drop in temperature at the next differential element up in the riser [DNS]. But before this a multi-lumped model is to be considered along with possible reaction schemes and there kinetic parameters. SEVEN LUMP KINETIC MODEL For this purpose a seven lump kinetic model proposed by Mehran Heydari et al. (2010) is used. They divided the model into seven lumps namely; VGO/Coker Naphtha, Clarified Oil, Light Cycle Oil, gasoline (LCN, MCN, and HCN), LPG, Dry gas and Coke. The schematic flow diagram is as follows; (Figure: 5- Seven lump kinetic model in FCCU) In order to develop a mathematical model for this particular system, certain assumptions has to be taken, they are as follows; The riser is an one dimensional ideal plug flow reactor with no radial and axial dispersion Reactor is an adiabatic riser Feed viscosity and heat capacities of all components are constant Fluid flow is not affected by the coke deposition on the catalyst Feed is vaporized instantaneously in the riser entrance All cracking reactions are taking place in the riser The model considers seven lumps and eighteen reactions and eighteen kinetic constants. Molecular weights of different lumps and boiling ranges are given [DNS] in the table below; (Table: 5- molecular weights and boiling ranges of lumps) j Lump Molecular weight (Kg/ Kmol) Boiling range (oC) 1 VGO 418.7 349 620 2 CLO 291 232 -567 3 LCO 226 170 392 4 GASOLINE 114 30 228 5 LPG 65 6 DRY GAS 30 7 COKE 12 Values of kinetic constants and activation energies along with heat of reactions for each reaction are given in the table below ([DNS], [Mehran Heydari], [Praveen ch. shishir sinha]); (Table: 6- reaction schemes with kinetic parameters) Reactions Rate constants (m3/ kg cat. hr.)

To the family I guess everyone experiences at least one terrifying event in his or her lifetime. How we assimilate the event shapes our attitudes, or maybe vice-versa. It can become the catalyst that lead, to phobias; sometimes it even earns itself a fancy title with â€Å"syndrome† attached to the end of it. I just call it a memory, but one I shared with eight other people. In a north central Indiana cornfield, not far from Indianapolis, my father returned to his chores in the field after a brief rain shower had passed. The edge of an enormous thunderstorm, laced with brilliant lightning, had passed overhead and it seemed as if the worst of the storm was over. Life was not easy on the fertile soil of Wabash County, Indiana, on May 25, 1966. For my family, life was about to become even harder. A muffled roar in the distance grew louder and sharper. As dad began to move toward the house, he realized that the low, indistinct form in the distance was not rain or a patch of fog. It was a rotating transparent funnel, beneath a dark mass of cloud. It extended from under the southwest corner of the thunderstorm. An occasional snake-like form would briefly appear within the cloud, and then suddenly vanish. It was coming directly toward our farm. The next time he looked, three or four contorted and transparent columns would briefly circle the center of what looked like a patch of swirling mist. The cloud looked nothing like the thin funnels and ropes that we had seen in the distance every few years. Dad now ran at full speed for the house, trying with each breath to shout "Twister!" Within the next few seconds, nine people would make life or death decisions about self-preservation, about prized possessions, and about family members. The rotating cloud had changed from transparent mist to a solid brown mass, at the edge of the newly

Political Transitions in America Essay -- American History, Politics a

As life began in the new world many people that have traveled wanted to live in a new atmosphere. People sought out wealth, fortune, freedom and wanted to express their ideas and beliefs as they could have not in their own countries. The new world gave these settlers an opportunity to start their new lives and way of life. One aspect of their new lives was how they wanted to be ruled and their political ideas. Political transitions have occurred throughout the beginning of the settlement of the new world from the British colonies to the first president with a central government then the secession of the south and Civil War until Richard Nixon and the Watergate Scandal. The English colonies were the starting basis of the new world. Jamestown, Massachusetts, and Pennsylvania all had their own ways of governing their people. Jamestown’s first political structure was the House of Burgesses which was the first government and was limited by the governor and Joint Company to decide. Also all free men could vote, but later on this was limited to white land owners. Many of their political problems were mainly expansion because farmers wanted more land and problems with the Native Americans. One notable issue was Bacon’s Rebellion which was a revolt against the royal governor of Jamestown who refused to fight back against the attacking Native Americans. About 300-600 people marched into Jamestown and burned down the city and Bacon also died, furthermore this was one of the beginning issues of western expansion. Another starting settlement was Massachusetts whose government was highly tied to the church. The members of the church congregation ha d full legal rights to making laws in the land. They were Calvinists who believed that God had... ...in D. Roosevelt has been elected as President. During this presidency Roosevelt introduced two major New Deal programs that were aimed at the industrial and agricultural recovery from the great depression. The first was the National Recovery Administration where labor leaders were equally determined and workers had a maximum work hours and minimum wage was created. Then the focus on the new deal changed from recovery to reform. (Divine, #646- Throughout American History the Political transitions that have occurred helped create a strong hope in the people today. The colonies that began in the new world have prospered into this great nation going through many conflicts and problems, from the war for independence to secession and the civil war to the great depression and recovery. These political transitions helped make America be what it is today; A great nation.

Concord University Department of Education :: Colleges Education Teaching Essays

Concord University Department of Education Philosophy Statement Forest Witcraft once said, "One hundred years from now, it will not matter what my bank account was, the size of my house, or what kind of car I drove. But the world may be a little better, because I was important in the life of a child." Teachers are not just educators; they are parents, social workers, nurses, and even friends. I believe that a good teacher can play all of those roles and more at the same time, without wavering. Children are not only our future, but they are our present. Without children, there is no hope, no love, or no potential. If our children cannot look to us, educators, as role models, who will they look too? I feel that the only way to become a good role model is to be an effective teacher. By using an open mind and an open heart, I plan to touch the life of a child in a positive, educational manner. For if one life can be forever changed, so will mine. The definition of education is â€Å"the action or process of educating or of being educated, knowledge and development resulting from an educational process† (Webster Online Dictionary, 2004). We are not just talking about teaching, we are talking about effective teaching; Bringing a child from dark to light when it comes to learning. But how do we teach effectively? I believe motivation is the best key. If you cannot motivate your student’s to their best, then you’re not being an effective teacher. For this motive, teachers should make the learning process fun. If learning is fun and entertaining, students learn and don’t even realize it. Also, to be an effective teacher we must have high standards and high expectations. High standards and expectations make the students expand their minds and they are forced to excel in their work. But can you force students to excel? Yes, with the proper incentive. This then brings us back to motivation. As teacher, we should not strive to be good, but strive to be the best. For if we as instructors reach for the best, so will our students. Our attitudes are greatly reflected onto our children. I remember so many times having teachers who were just at school for the pay check and how it greatly showed in their work. I also remember teachers who were genuinely excited about teaching.

Fat and Water Soluble Vitamins

Fat and Water Soluble Vitamins Sheila Grant SCI/241 December 23, 2012 Tia Patterson Fat and Water Soluble Vitamins All types of vitamins are essential for everyone to include in their diet to maintain a healthy lifestyle. They are classified into two different classifications. There is fat soluble which are A, D, E and K. The other classification is water soluble vitamins, which is vitamin C and B. Vitamin C and B are also known as complex group vitamins. Vitamins are crucial for the human body to properly function. Foods we eat have different kinds of vitamins, some may have one and some many have multiple vitamins.Watching what you eat will ensure the body is getting plenty of vitamins for your body to function properly. Our body does not make the vitamins we need to sustain life; therefore we need vitamins to maintain proper function of the body system. Vitamins we consume from the foods we eat are one part of a healthy diet. Vitamins help our body function like cell growth, energ y metabolism, immune system, nervous system, circulatory system and reproduction system. Vitamins help fight off infections and as we get older the risk for infections increase. Vitamins are just as important to babies as it is the elderly.Everyone will benefit and have a healthy diet if vitamins are crucial in their diet. The fat soluble vitamins are A, D, E and K. Vitamin A is a crucial vitamin because it helps the eyes and skin to be healthy. Vitamin A is important because it helps teeth and bones to be strong. Vitamin A is also beneficial to the bodies reproductive and immune systems. There are some ideal sources of vitamin A for a healthy diet. They are carrots, sweet potato, tomatoes, green beans, bell peppers, and spinach. The deficiency of Vitamin A could cause diarrhea, intestinal infections, inflammation of the eyes and keratinization of skin and eyes.An individual who consumes too much Vitamin A could cause, blurred vision, enlargement of liver and spleen, loss of hair, s kin changes, and increased pressure of skull. Vitamin D vitamins help regulate the use of phosphorous for our body. According to Nutrition, â€Å"Active vitamin D is needed to maintain normal blood levels of the minerals calcium and phosphorus. Calcium is important for bone health, but it is also needed for proper functioning of nerves, muscles, glands, and other tissues† (Grosvenor & Smolin, 2006). Vitamin D can be made in the body and can be absorbed through the skin by sun exposure.When the body has low levels of Vitamin D, the body stores inactive Vitamin D and activategbs it through the liver and kidneys. Vitamin D deficiency in children will cause rickets which is smaller rib cages and bowed legs. Deficiency in adults is Osteomalacia, which causes bone loss. When an individual consumes an excessive amount of Vitamin D, they can have high amounts of calcium in the blood and urine. It also could cause heart problems. Some excellent sources of Vitamin D are salmon, eggs, m ilk, tuna, and cod liver oil.Vitamin E maintains the nerves and the reproductive system to help keep them healthy. The benefit of Vitamin E is it promotes healthy skin. There are excellent sources of Vitamin E found in food, they are; sunflower seeds, almonds, turnip greens and mustard greens. Deficiency of Vitamin D could cause anemia in low birth weight babies. This would happen if starvation was a cause though. Overconsumption of this vitamin causes massive nausea and digestive track conditions. â€Å"Vitamin K is an essential vitamin that is needed by the body for blood clotting and other important process. (Leopold, 2010) The benefits of vitamin K are used in management of extreme bleeding. Too much bleeding can occur from a deficiency of vitamin K mainly with the use of blood thinning agents. Some symptoms related to the deficiency of vitamin K are; nose bleeds, broken blood vessels, blood in urine and bleeding gums. Some problems with vitamin K when excessively taken is upse t stomach and really high doses the person may have an allergic reaction. Excellent sources for Vitamin K are, Brussels sprouts, broccoli, celery, tomatoes and spinach.Water-soluble vitamins are B-complex and Vitamin C. These two vitamins are not stored in the body and will need to be replaced every day. Water-soluble vitamins dissolve in water and therefor they are eliminated in urine. B-complex groups have eight water-soluble vitamins which are; niacin, folate, biotin, pantothenic acid, thiamin and riboflavin. The sources of the vitamins are found in, grains, vegetables, meats, eggs, milk and dairy. B-complex vitamins help the body get energy from the food we eat. It also helps aid in protein metabolism, and helps many body functions.Citrus fruits like oranges are ideal sources for Vitamin C. Vitamin C help maintain blood vessels, bones and teeth. Vitamin C gives us protection again immune system deficiencies, cardiovascular disease and prevents skin wrinkling. In some countries b eriberi, pellagra and pernicious are three common B-vitamin deficiencies. When people overeat certain types of food the deficiency can cause cracks at corners of mouth, impaired growth, mental confusion and eyes sensitive to light. Deficiency to Vitamin C could cause bleeding gums, sore joints, increased infections and easily bruised.Toxicity among the two vitamins can cause diarrhea, bloating, kidney stones, abnormal liver function and irritability. In some cases Vitamin C has the power to diminish the threat of different types of cancer, heart disease and cataracts. Vitamin C serves as an antioxidant as it can fight off infections they may cause harm to our bodies. References Leopold, D. C. (2010, December). Vitamin and Lifestyle Guide.

(Leopold, 2010) The benefits of vitamin K are used in management of extreme bleeding. Too much bleeding can occur from a deficiency of vitamin K mainly with the use of blood thinning agents. Some symptoms related to the deficiency of vitamin K are; nose bleeds, broken blood vessels, blood in urine and bleeding gums. Some problems with vitamin K when excessively taken is upse t stomach and really high doses the person may have an allergic reaction. Excellent sources for Vitamin K are, Brussels sprouts, broccoli, celery, tomatoes and spinach.Water-soluble vitamins are B-complex and Vitamin C. These two vitamins are not stored in the body and will need to be replaced every day. Water-soluble vitamins dissolve in water and therefor they are eliminated in urine. B-complex groups have eight water-soluble vitamins which are; niacin, folate, biotin, pantothenic acid, thiamin and riboflavin. The sources of the vitamins are found in, grains, vegetables, meats, eggs, milk and dairy. B-complex vitamins help the body get energy from the food we eat. It also helps aid in protein metabolism, and helps many body functions.Citrus fruits like oranges are ideal sources for Vitamin C. Vitamin C help maintain blood vessels, bones and teeth. Vitamin C gives us protection again immune system deficiencies, cardiovascular disease and prevents skin wrinkling. In some countries b eriberi, pellagra and pernicious are three common B-vitamin deficiencies. When people overeat certain types of food the deficiency can cause cracks at corners of mouth, impaired growth, mental confusion and eyes sensitive to light. Deficiency to Vitamin C could cause bleeding gums, sore joints, increased infections and easily bruised.Toxicity among the two vitamins can cause diarrhea, bloating, kidney stones, abnormal liver function and irritability. In some cases Vitamin C has the power to diminish the threat of different types of cancer, heart disease and cataracts. Vitamin C serves as an antioxidant as it can fight off infections they may cause harm to our bodies. References Leopold, D. C. (2010, December). Vitamin and Lifestyle Guide.

Newton Weights Essay

As it is known, different materials have different properties. They act differently under different circumstances. There are a number of properties of matter which can be explained in terms of molecular behaviour. Among these properties is elasticity. Intermolecular forces: these are electromagnetic forces between molecules. The strength and direction of these forces differ in accordance to the separation of the molecules. Materials are often subjected to different forces. Forces can be distorting, that is they can alter the shape of a body. Two distorting forces I shall look at are tension and compression. Tension/tensile stress, more generally referred to as stretch, happens when external forces (larger red arrows) act on a body so that different parts of that body are pulled to go in different directions. In most materials, the intermolecular force (smaller aqua arrows) of attraction shows resistance to these external forces, so that once the external forces have abated, the body resumes its original shape/length. Compression/compressive stress, more generally referred to as squashing, happens when external forces act on a body of material so that different parts of that body are pushed in towards the centre of the body. In most materials, the intermolecular force of repulsion acts against these external forces, so that when the distorting force is removed, the molecules return to their original arrangement and spacing. Materials that do this are known to have the property of elasticity. In short, elasticity is the ability of a material to return to its original shape and size after distorting forces (i.e. tension and/or compression) have been removed. Materials which have this ability are elastic; those which do not have this ability are considered plastic. This always happens when the distorting force is below a certain size (which is different for each material). This point where the body will no longer return to its original shape/size (due to the distorting force becoming too large) is known as the elastic limit (which differs from material to material). As long as the distorting force is below this size, the body that is under the external forces will always return to its original shape. As the body is put under more and more stress (distorting force), the body strains (deforms, extends) more and more. Right up to the elastic limit, the body will continue straining, in accordance to the size of the stress. This is where Hooke’s Law comes in. Hooke’s Law states that, when a distorting force is applied to an object, the strain is proportional to the stress. For example, if the load/stress is doubled, then the extension/strain would also double. However, there is a limit of proportionality (which is often also the elastic limit), only up to which Hooke’s Law is true. Since the strain is proportional to the stress for different materials where Hooke’s Law is true, then there should be a fixed ratio of stress to strain for a given elastic material. This ratio is known as its Young’s Modulus. Young’s Modulus can be calculated from the stress and the strain of an object under tensile/compressive stress. e = change in length/extension of object, in cm p = original length of object, in cm a = cross-sectional area of object, in cm2 f = size of force applied, in newtons For example, the Young’s Modulus of Mild Steel = 2 x 1011 N m-2 Copper = 11 x 1010 N m-2 Hooke’s Law and Young’s Modulus apply to most elastic materials, with the exceptions. A special shape which material can be bent into to in order to optimize use of the elasticity of a material is a spring. Springs are used by us everywhere: in seats, mattresses, cars, toys, and all other sorts of necessary objects and items we encounter in our daily lives. They are normally made from metal, though they can come from plastics, rubber or even glass. When compressive stress is applied to a spring, the spring noticeably ‘shortens’, though the actual length of the body material shortens very little. It is due to this special shape of springs that let it do this. The same occurs when tensile stress is applied. When a spring is being extended or pulled on, it may seem the spring is changing length dramatically, but in actual fact the spring’s body material relatively doesn’t change shape at all, but rather the shape of the body is more spaced out. AIM My objective in this experiment is to find out how a spring varies in length with added load. I also want to witness Hooke’s Law in action, and I want to observe the behaviour of the spring/s even after the load added causes the stress in the spring to exceed the elastic limit. PLAN My experiment is fairly straight forward to set up and carry out. In my experiment the data that I intend to assemble is the extension of the spring each time new/extra load is added to it. It is necessary that I use the most appropriate equipment for my experiment, hence I have chosen to use a retort stand which will hold up the spring and its weights up, a second retort stand from which a meter rule will be suspended. The metre rule will be right up against the spring, so as to ensure an accurate reading. There is no evidence that I can take before hand, other than the material of the spring. This entire experiment has to be as accurate, fair, precise and reliable as can practically be, but it is only possible to make it so to a certain extent. For instance, I cannot be absolutely sure that that all Newton weights weigh exactly 1000 grams, nor is it practical to find a ruler that is absolutely accurate. Hence I am forced to settle for the metre rule, which is accurate to about 1 millimetre, and I will be aware that the Newton weights will be within an accuracy of about i 20 grams. These factors will not really be in my control; however I can reasonably account for them when I construct a graph from my table by using error bars for each point plotted. Another measure I am taking is that I shall not be the only one to take readings from the metre rule; I shall have two other peers who will also be reading off the same metre rule. From these 3 readings I shall draw up averages of level of weight applied to the spring. To be practical and observing at the same time, I must choose an appropriate extent and range, as well as appropriate integers, for the data that I intend to collect. I will be going to take the first measurement as the length of the spring when there is no mass attached to it. The last measurement shall be right up to when the spring can no longer hold on to the weights. I have a rough idea of the spring that I shall use, and I am assuming now that the spring shouldn’t be able to hold much more than 13 kg. I shall be adding the weights one at a time (one Newton/kilogram at a time), and I shall be taking measurements at each of these intervals. The measurements that I shall take of the length of the spring will be in millimetres. So basically, once I have set up the entire apparatus, I shall start off taking the measurement of the spring when it is free of load, then let my peers take theirs. Then I shall add a Newton weight one at a time, taking measurements with my helpers each time I add one. Of course we’ll be wearing our goggles, because I don’t want to take any risks. 1) Collect equipment. 2) Prepare apparatus as shown in diagram. 3) Record the length of the spring when it is load-free, to cm, in the prepared table for results. 4) Add a weight/mass of 1 kg or 1 N, and then take the new length of the spring. Record in the prepared table for results. 5) Continue adding on weights/masses of 1 kg, recording the length of the spring each time in the prepared table for results. This should be carried on until the weights can no longer be attached to the hanging spring. APPARATUS. The apparatus that I shall need set up for my experiment consist of the following items: 1. Retort Stands (x 2) 2. Boss and Clamps (x 2) 3. Metre Rule 4. Spring (length: 50 mm) 5. Newton Weights (x 15 approximately) Other items I shall need are three pairs of goggles. SAFETY I must consider my safety when working in the laboratory. It is common when this type of experiment is carried out that when a weight or anything for that matter is suspended from something as unstable as a hanging spring, the item in being suspended is prone to fall.

Attitudes Towards Technology in the Han and Roman Empires

Attitudes Towards Technology in the Han and Roman Empires DBQ 2 Technology is always changing. New ideas are being introduced, and innovations to current technologies are always taking place. Some may see changes in technology as a vital and helpful thing, while others may oppose. Upperclassmen’s attitudes toward technology, especially advancements within technology, in the Han Empire, were very approving and encouraging. In the Roman Empire, the majority of upperclassmen’s attitudes toward technology were very supportive, as long as the technology or advancement was invented by someone of a highly philosophical mind.Roman upperclassmen in general had positive attitudes towards technology, as well as innovations in technology. Some higher classmen, however, looked highly upon themselves, and felt like anything not originating from their minds or hands was below them. Some philosophers had the attitude that anything they did not invent was only mediocre and sufficient, i nstead of excellent and great. (Doc. 7) Along with that, some upper class political leaders believed that it was vulgar and degrading of any man to be employed in any field of labor. Doc. 5) I placed these documents in a group together because of the fact that both of the authors of the documents had extremely opinionated outlooks on technology formed by lower classmen. Both authors stated in their documents that anything created by a lower classman was only mediocre in comparison to improvements in technology created by a higher classman like a philosopher. Therefore, their attitudes toward technology was positive†¦ as long as it was created by a man higher up in society.In Document 7, an upper-class Roman philosopher and adviser to Emperor Nero named Seneca expresses that any tools created by men who are not philosophers are mediocre and insignificant. His point of view is that he feels that the minds that did create the current technological advances in tools were nimble and sharp, but not great nor elevated. His attitude towards these breakthroughs in technology are this way because of his role in society. He is a philosopher, so it his is of his role to think with an abstract mind, imagining things from an â€Å"outside of the box† type of erspective. Because philosophers are trained to think this way, they would be able to create tools and new innovations in technology that could completely change how technology was viewed, leading their empires to greater and greater heights. But because of the lack of training and experience in abstract thought, he felt that normal men would tend to come up with good tools that were well built and could assist them in their day-to-day lives, but nothing groundbreaking that could have everyone captivated and amazed like â€Å"great and elevated minds† like his could invent.While some Roman upper class members liked only the technology invented and improved by elevated minds, that wasn’t the cas e for all of Rome. A Roman political leader named Gaius Gracchus set up a new system of road building, paying equal attention to the functionality and the appearance of the roads. He helped travelers keep track of distance by measuring out every mile and placing a column there. As well as the columns, Gracchus placed large stones on either sides of the road at lesser intervals, so it would be easier for those who road horses to mount them. (Doc. 6) Another brilliant advancement in technology was the aqueducts.Six of the aqueducts flowed into covered containers. Then, the volume was measured by means of calibrated scales. The use of the water was not only used for what was needed, but the water was also utilized for pleasure purposes. (Doc. 8) I grouped these two documents together since they both displayed advancements in technology without being discriminatory against those who were in lower classes. Because they both show the advancements in technology, it is evident that the atti tude toward technology was extremely positive. (Doc. 7) members of the Han Empire accepted and embraced new technologies.In fact, many government officials often implemented new ideas in their societies. For example, Tu Shih, who was the governor of Nanyang, invented a water-powered blowing-engine for the casting of iron agricultural implements that allowed people to enjoy great benefit for little labor. Not only has his invention been widely used, but it has also been adopted and innovated by those who use it. (Doc. 4) Fuxi, though only a mythological emperor, was said to have invented the pestle and the mortar. Throughout the years, his invention was cleverly improved in such a way that the ending benefit was increased a hundredfold. (Doc. ) There were times, as well, when government officials wrote to local officials describing exactly what needed to be done to assist in current problems. Though the government officials came up with such an in-depth plan and strategy, the local o fficials ultimately made the final call, tailoring the governmental plan to fit the individuality of each town. (Doc. 1) I grouped these documents together because they all involve a leader inventing something, with lower classmen innovating the invention. This proves that the Han Empire had a positive attitude about technology, and were still completely open to the aspects of change and advancements.In Document 3, an upper-class Han philosopher named Huan Tan expresses, with great enthusiasm, his point of view of the evolution of the pestle and the mortar throughout the years. In the document, it goes in depth describing all of the innovations and advancements the pestle and the mortar have gone through. This exemplifies the fact that Huan Tan’s attitude towards innovations in technology was devoutly positive. In Document 3, Huan Tan conveys the story of how Fuxi, who, though mythological, was an emperor, created something, which was improved by regular commoners.This shows that unlike the Roman philosopher in Document 7, Huan Tan shows no discrimination against the lower classes. He does not feel that in order for truly excellent work, you must have a philosopher title. He understands that ordinary people can be the most brilliant at times, and finds the entire concept of advancement in technology astounding. An additional document I feel would be beneficial in helping to convey my thesis would be a journal entry from the point of view of a Han Peasant, depicting their attitude towards the new advancements in technology.This is needed because every document we were given was written from the perspective of an upperclassmen. In order to more accurately answer the question, I feel like we should have an understanding of every socioeconomic class. I also think that in order to more efficiently analyze Document 2, we need a comparison with the journal entry from a Han Peasant. Because Document 2 talks about how individual family’s tools were better than the government-made ones were, I think that a journal entry explaining their thoughts on family-made tools versus the government-made tools would help give a better understanding of the document.

Operational Management Discussion - Assignment Example Scheduling has also been enhanced through the functions of various programmable information systems. What is more, there has been the creation of the new concept of user-based scheduling whereby it is possible to make scheduling arrangements that fits the needs of different customers. Before, it was common that service users would be piled up in waiting for their turns to receive service. This has however become a thing of the past. With the current healthcare dynamic, there has also been an all-new and important concept about location, commonly referred to as virtual location. Virtual location refers to a situation whereby service users are able to receive services and care without the service provider being there in person. This has been done on the wings of the technology of multimedia communication such as video calling. Without an iota of doubt, the current healthcare dynamic has been a positive development that has helped service providers within the various stakeholder bases t o be more effective and efficient. However, such effectiveness and efficiency will not happen to anybody but only to those who put their houses in place to embrace the changes (Meredith and Shafer,

Services Marketing - Essay Example There are additionally behavioral and attitudinal perspectives. A gander at these ideas will clear up what "client loyalty" truly is, and this is vital because having a robust understanding of the idea is vital if one wants to plan a prize project where dependability upgrade is the essential target. Additionally, the fast development of online transactions in service commercial ventures brings up paramount examination issues about the levels of fulfillment and dependability in the online environment, and the relationship between fulfillment and devotion online with respect to offline. Some latest studies demonstrate that there may be deliberate contrasts in client devotion for items and services picked online versus offline. Clients are central to the achievement of a business since a business without clients is not a legitimate business. Whether individuals are beginning or have are since quite a while ago settled, a great deal of time and cash is used in attempting to increase new clients. It is vital for ambitious people to recall that a loyal client can be generally as significant (if not more essential) than new one and this aspect is known as relationship marketing. This is because the business people do not need to invest as much time and cash promoting to them in light of the fact that they comprehend what the business people offer them. Moreover, it goes past simply having clients that are fulfilled, the ambitious people need to have loyal clients. Dedicated clients have a tendency to purchase more significantly, they talk more which means an entire load of free verbal publicizing for the business or organization (The business donut 2014). Subsequently constructing an exceedingly faithful clien t base ought to be the establishment of a fundamental business methodology. In making a dedicated client custom, the business people will unavoidably bring down their

The entrepreneurial organization Essay Example | Topics and Well Written Essays - 2250 words

The entrepreneurial organization - Essay Example They can only thrive in an environment of relative freedom. Under industrialization, bureaucracy was the dominant form of organization. The factory was designed to produce standardized products; the bureaucracy was designed to produce standardized decisions. Many major corporations of today developed in an industrial society, based on a bureaucratic model of machine-like division of function, routine activity, regularity, seeming permanence, and a long vertical hierarchy. It was a world of mass markets uniform goods and services, and long production lines. During the 1990's, however, the top-down authoritarian management style began yielding to a networking style of management. Horizontal communication in a networked environment is freer and more fluid, with few bureaucratic barriers. In the new style of management, people learn from one another peer to peer, everyone is a resource for everyone else, and each person gets support and assistance from many different directions. In any bureaucratic structure, people tend to feel they cannot change their environment and thus may never seek the information that might change it. In sharp contrast, the new emerging form of organizations supports change, innovation, and individual initiative to an optimal degree. Intrapreneurship simply represents an organizational culture that allows employees flexibility and authority in pursuing and developing new ideas. Intrapreneurship is nothing but entrepreneurship practiced within the context of a large established organization. An intrapreneur is involved in the "venturing" process, that is, in developing a new business inside a corporation from its initial idea until it becomes a viable business. Often an intrapreneur must lead a project with an entrepreneurial vision , willingness of using power , leadership, motivation and ability to overcome resistance and barriers (Johansen, 2002). Joseph Schumpeter (1883-1950) was a pioneering researcher in the field of entrepreneurship, he studied the role of the entrepreneur as an innovator, i.e., the person who develops a new product, a new market, or new means of production. Schumpeter distinguished between dependent and independent entrepreneurs, the former being those who are connected to an existing company, and the latter being those who start their own companies. Although coined and popularized by Gifford Pinchot in 1985, the term 'intrapreneur' (short for intra-corporate entrepreneur) essentially means what Schumpeter called a dependent entrepreneur. Several factors in organizations can have an influence on intrapreneurship/entrepreneurship. Usually, there are any number of barriers to innovation that can occur in organizations. Among all these factors and barriers, the degree of bureaucratic-style management within an organization can have the most adverse impact on the levels of individual initiative. 2. The Paradigm Shift Bureaucratic-style management is fading from the scene, albeit gradually. Mega corporations may be thriving, nonetheless their internal structures are becoming more geared towards innovation. Once considered a contradiction in terms, corporate intrapreneurship has become widely accepted in successful companies, such as 3M, Intel, and Coca-Cola.Also, in the fiercely competitive world of high

Information Security Essay Example | Topics and Well Written Essays - 3750 words

Information Security - Essay Example Although a voluminous amount of information which talks about cyber attacks has already been presented, there exist several lapses involving properly recognizing security defense weaknesses and how perpetrators breach computer security. Hence, the purpose of this paper is to address the aforementioned topics, which were not discussed in the previous work. Apart from reviewing security bypass strategies, a study design and possible ways to analyze future data will also be addressed. In the context of computers, the security of data will be difficult to manage if the criteria for proper management will not be converted to something that is measurable. Thus, the quantitative aspects cannot be overlooked because these will allow the researchers to better assess the strength of the system to put off any form of security breach to the system or its capability to hold off cyber attacks. This paper starts off with a brief review of the different research method designs: qualitative, quantitative, or both, and an explanation of the importance of each design over the other. After which, the research questions will be presented, followed by a detailed description of how the research design will be implemented including the inherent limitations and validity issues of the chosen design. Prior to discussing the process of data collection, the functions of the researcher will be briefly tackled. Thereafter, an explanation why the mixed method design was chosen over the other approaches will be provided, wherein the validity and quality of the data that will be retrieved using the said methodology will be established. Moreover, the ways of managing the collected data will also be described. A discussion of the mixed method design, in the context of holistic perspectives will follow, which will be used as a guide to analyze the retrieved data. It has been well established that the preconceived notions of the researchers over which research design to use, how

Discuss the contrasting literary styles used in James Baldwin's Essay

Discuss the contrasting literary styles used in James Baldwin's Sonny's Blues and Tim O'Brien's The Things They - Essay Example Literary Analysis Paper The stories of James Baldwin and Tim O’Brien have a common element amongst them, mentioned explicitly; the attribute of undergoing struggle. In O’Brien’s book, struggle and hardships can be seen through the eyes of American soldiers fighting in the Vietnam War, whereas in Baldwin’s tale, Sonny is seen fighting life and addictions in order to patch his relationships with other people around him as well as himself. ‘The Things They Carried’ is about experiences that the soldiers, led by Tim O’Brien went through, which included tangible as well as intangible important elements. These included emotions and feelings like fear, dread and guilt, as well as the kind of machines and guns which formed an inherent part of their routine lives in the War. ‘Sonny’s Blues’ is about a young heroin addict, set in a post World War era, depicting a great amount of political and economical tension raging in Ameri ca at the time, with respect to culture and the old arts. The book is a story full of symbolism; in this particular tale, O’Brien has marked a very vivid description of all the objects that the various soldiers carry with them.

White-collar crime and criminal theories Essay Example | Topics and Well Written Essays - 500 words

White-collar crime and criminal theories - Essay Example Based on the rational choice theory, individuals engage in crime deliberately, and they have the conscious that the act they engage in is criminal. The theory also holds that people engage in white-collar crime on their own and as a result of their own free will (Shover & Hochstetler 2). The rational choice theory states that individuals willing to engage in white-collar crime first evaluate their actions. Based on their evaluation of the situation, the individual then makes an assessment on whether there is a possibility that they will complete the action without any sanctions. The rational choice theory is also states that people who carry out white-collar crime tend to be motivated to do so because of the desire to make illegal gains (Shover & Hochstetler 4). The theory further argues that the entities and individuals engaging in white-collar crime know the consequences of such a crime, but they choose to ignore these consequences and engage in crime regardless of the consequences. For example, a white-collar crime like fraud is carried out intentionally with the aim of getting unscrupulous gains. Corporate entities also engage in white-collar crime intentionally since they know the consequences of such crime (Vito and Jeffrey 63). The other theory, which explains white-collar crime, is the social disorganization theory. According to this theory, the factors around a person have a profound impact on the possibility to commit a crime. The conflicts and inconsistency of institutions play a key role in determining whether the white-collar crime will be committed (Payne 224). The key theorist who advanced the social disorganization theory was Edwin Sutherland. According to him, the social disintegration of society can be regarded as the basis upon which white-collar crime takes place. The disorganization of institutions contributes to white-collar crime since it enables criminals to have an easy way.

Improving Construction Safety in Saudi Arabia Dissertation

Improving Construction Safety in Saudi Arabia - Dissertation Example 1 Introduction It is rather unfortunate, but true, that the construction industry around the world had developed a reputation for being the industrial sector that presents higher statistics for industrial accidents, fatalities and deaths than any other (Coble, 2000, Pp. vii - viii). United States Department of Labour for the year 2006 indicated that construction fatalities represented about 21% of the total work force fatalities (Lambeck, 2009, Pp. 72 – 74). However, efforts directed towards continuous improvement in construction safety in many countries, including Japan, South Korea, China, etc. demonstrate that it is possible to reduce the incidence of occupational injury, serious accidents or deaths (Poon, 2008, Chapter 1). Statistics for construction industry accident frequency rates per million of men hour worked for Singapore suggest that with an accident frequency rate per million man hours of 3.5 for the construction sector in comparison to 1.9 for all other industries help to illustrate the notoriety of the construction sector (Poon, 2008, Chapter 1). However, results for Japan, Korea and Hong Kong demonstrate improvement with effort. Reports about the construction sector in Saudi Arabia suggest that it is possible to do more to bring about an improvement in health and safety for those working in the construction sector (Al Omani, 2008, â€Å"Does Saudi Arabia need a health and safety boot?†), (Migrant Rights, 2011, â€Å"FAQ†) and (Construction Week, 2010, â€Å"Construction sector must embrace safety culture†). Like in any other industry, accidents in construction lead to injury, possible loss of life, additional work and added costs (Li Wai Chung, 2006, Chapter 3). Time losses for the injured, delays in completion of construction, medical expenses, damage to... The intention of this study is the term ‘safety’, which refers to an absence of danger, as often partnered with the term ‘health’ within the context of work in general and for construction work. Because human health and welfare are of concern to the society, a corporate responsibility exists to ensure that minimal risks exist to the health and safety of employees so that individuals, families and the society at large receives protection and remains free from catastrophe. Thus, the legal system in England and in many other nations emphasises a duty to care, an absence of negligence and criminal responsibility for injury to ensure that those who use employees for business do so in a manner that will minimise harm to these individuals, especially when the business motive is to present profits. The law reflects values in a society and without values that emphasise health and safety it is likely that the risks associated with occupations will present undue harm t o individual members of a society and to society itself. Hence, a global concern exists for health and safety in construction and many nations around the world have enacted laws and regulations to emphasise health and safety in occupations, based on recommendations of international organisations, including the International Labour Organisation (ILO) and national values. However, a need exists to ensure that laws and regulations are effective and practical.
