Nanotyrannus - Facts and Figures

Name: Nanotyrannus (Greek for tiny tyrant); pronounced NAH-no-tih-RAN-us Habitat: Woodlands of North America Historical Period: Late Cretaceous (70 million years ago) Size and Weight: About 17 feet long and half a ton Diet: Meat Distinguishing Characteristics: Small size; forward-facing eyes; sharp teeth About Nanotyrannus When the skull of Nanotyrannus (tiny tyrant) was discovered in 1942, it was identified as belonging to another dinosaur, Albertosaurus--but upon closer study, researchers (including the famous maverick Robert Bakker) speculated that it might have been left by an entirely new genus of tyrannosaur. Today, opinion is divided into two camps: some paleontologists believe Nanotyrannus indeed deserves its own genus, while others insist that its a juvenile of Tyrannosaurus Rex, or some other established tyrannosaur genus. Further complicating matters, its possible that Nanotyrannus wasnt a tyrannosaur at all, but a dromaeosaur (the class of small, carnivorous, bipedal dinosaurs better known to the general public as raptors). Usually, additional fossil specimens help to clarify matters, but no such luck with Nanotyrannus. In 2011, word leaked out about the discovery of a complete Nanotyrannus specimen, unearthed in close proximity to an unidentified ceratopsian (horned, frilled dinosaur). This has led to all kinds of fruitless speculation: did Nanotyrannus hunt in packs to bring down larger prey? Were its unusually long hands (rumored to be even longer than those of the full-grown T. Rex specimen Tyrannosaurus Sue) a unique adaptation to its ecosystem? The trouble is that this putative Nanotyrannus specimen, nicknamed Bloody Mary, remains in private hands, and has not been made available for expert analysis.

The World Of Color By B Dubois - 922 Words

The Scramble for Africa can easily be defined as the forced invasion and division of African countries among European superpowers. Those powers included Great Britain, France, Spain, Portugal, Italy, Germany, and Belgium. Each superpower wanted control over a certain area on the continent and would do anything to ensure that their area remained in their best interest. To bring the conflicts to the forefront, the countries participated in the Berlin Africa Conference in 1884-1885. In this conference, the issues of Anglo-German relations and everybody’s control in Africa were discussed. As a result of the conference, European control began to overtake the African continent and imperialism became a giant part of the European mark. In his book, â€Å"Worlds of Color† W.E.B DuBois discusses the idea of whole colonial enterprise stating that the problem the world faces is the color line. This can easily be interpreted as Dr. DuBois giving the idea that if World, more speci fically European superpowers stop viewing the color line and Africa’s color line as something less than them a lot of the world’s issues could be detected and fixed. But more importantly, Dr. DuBois is stating that without the Worlds of Color, European industrialization would not exist.

Essay on Federal Reserve Act - 1877 Words

The Federal Reserve: A Knight in Shining Armor quot;To suffer either the solicitation of merchants or the wishes of government, to determine the measure of the bank issues, is unquestionably to adopt a very false principle of conduct.quot; nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;-Henry Thornton, 1802 nbsp;nbsp;nbsp;nbsp;nbsp;The banker was frantic.

Something had to be done that would provide for a flexible amount of currency as well as provide cohesion between banks across the United States. (Hepburn, 399) This knight in shining armor, as described in the story of the bank run, was the Federal Reserve. The Federal Reserve Act of 1913 helped to establish banks as a united force working for the people instead of independent agencies working against each other. By providing a flexible amount of currency, banks did not have to hoard their money in fear of a ban k run. Because of this, there was no competitive edge to see who could keep the most currency on hand and a more expansionary economy was possible. nbsp;nbsp;nbsp;nbsp;nbsp;The evolution of the Federal Reserve did not begin on December 23, 1913 with the passage of the Federal Reserve Act. Rather, it began with the Banking Panic of 1907, the most severe of the four national banking panics that had occurred in the precious thirty-four years. In response to this panic, a committee was established to find the flaws of the current banking system. This committee, the National Monetary Commission, found there were two main flaws dominating the system. First, the currency was not responsive to changes in demand. (Born...13).

In the story the Golden Kite and Silver wind the two lands are continuously trying to best each other while not getting anywhere until finally coming up with a solution in the end. Allegory is shown throughout the story based on the Cold war, which is expressed by building walls which leads to the theme being that working together is better than having enemies. They never combated, but tried to surpass each other by increasing weaponry. The Mandarin of one of the towns, commands, â€Å"you raisers of walls must go bearing trowels and rocks and change the shape of our city!.

Likely World Fifty Years from Now Political Aspects

Question: Write about the Likely World Fifty Years from Nowfor Political Aspects. Answer: Introduction Currently, there are a lot of revolutionary changes being experienced across the world regarding social, economic and political aspects. Therefore, this paper will focus on discussing and creating the impression of the kind of world that might exist fifty years from now based on class discussions and observed trends. The Kind of World that might Exist Fifty Years from Now The countries perceived to be powerful about military capabilities have been involved in unending war issues which have raised security concerns over the years across the world. For instance, the issue of nuclear and biological weapons has taken center stage on the entire matter of compromised safety in the world. Countries like North Korea and Syria have embarked on a journey to make nuclear and atomic bombs thus making them threats to the rest of the countries. Fifty years from now, more nations will have joined the countries already producing these dangerous weapons hence making the whole world unsafe for human existence. It is happening because of the failed efforts to control such activities. NATO members like the United States of America and Canada have tried to impose sanctions on countries such as North Korea and Syria among others. There will also be possible segregation of the world regarding economic, social and political abilities among nations (Adrian Done, 2011, 100). Since the World War I and World War II, the most developed countries have formed alliances and have always exercised the influence they perceive to have on other nations under various mandates. For instance, there exists the North Atlantic Treaty Organization (NATO), African Union (AU) and the European Union (EU) among others. NATO members agreed to mutual assistance in case of an attack on any of the members. On the other hand, EU members agreed to carry out viable economic activities amongst themselves. This trend is likely to cause divisions because nations based on their locations will pursue their interests first neglecting other regions (Donald et. al. 2012). The recently witnessed exit of Britain from the European Union provides an example of the direction the world is following. It was also witnessed during the downfall of European C ommunism after the pulling out of Soviet power from Eastern Europe that happened during the second half of the twentieth century. Some countries like the U.S. have banned migrants from a majority of Arab countries from entering the nation. Although the move was not welcome, it will castigate the efforts of unifying nations across the world and instead, cause chaos and divisions in future. However, the policy seems to strengthen the Arab Nationalism characterized by resistance to Western ideologies and creation of a social order based on the arduous exposition of Islam. Terrorism is also likely to overwhelm the world in future (). The U.S was attacked on September 11, 2011, making the administration to declare war on terrorism." In response, the U.S launched attacks on Afghanistan. However, Taliban strongholds and rebellion remain high to date. The preemptive strikes policy against potential enemies by the U.S led to a prolonged war in Iraq. Unfortunately, several other terrorist groups such as ISIS and Alshabaab have emerged and have launched offensive attacks in different nations across the world. It is feared that if more terrorist groups continue to form, the security aspect in the world will be sabotaged thus making the world a war zone. References Adrian, Done. 2011.

Improving Healthcare Quality free essay sample

Improving Healthcare Quality Purpose The purpose of this paper is to identify aspects of quality improvement in healthcare. This research is conducted by examining and reviewing various literature regarding the definition and makeup of quality healthcare, need for improvements in healthcare, various quality measures or indicators and weighing the cost of improving healthcare quality. Defining Healthcare Quality Before any discussion can take place regarding improving healthcare quality, an examination of the definition of healthcare quality must be conducted. There are legitimately varying perceptions of what is consider to be the critical dimensions of quality healthcare. These views on quality largely results from the perspective one adopts as a patient, healthcare provider, health care manager, purchaser, payer, or public health official. The same health care experience may be assessed differently depending upon the person’s role. For example: ? The patient may view his or her experience with the health care system both by its outcome and personal feelings, such as whether the physician listened well, communicated clearly, and was compassionate as well as skilled in delivering healthcare services. ? A healthcare provider may view quality in a technical sense, such as whether an accurate diagnosis is made, whether a surgical procedure is performed proficiently and whether the patient’s health has improved. From this view, quality is the difference between what is technically sound and possible, and the actual practice and delivery of healthcare services. ? The health care manager, payer, or purchaser (employer health plan, or government program) may want to know if the healthcare services provided are cost effective. ? Public health officials may want to know if resources are being utilized appropriately to optimize population health and provided equitably within the population. Quality as defined in Clair G. Meisenheimer’s book, Improving Quality: A Guide to Effective Programs, is â€Å". . . the totality of features and characteristics of a health care process that bear on its ability to satisfy stated or implied needs; a process or outcome that consistently conforms to requirements, meets expectations, and maximizes value or utility for the customer. For the customer: getting what you were expecting and more; for the supplier: getting it right the first time, every time. The Institute of Medicine of the National Academies (IOM), a not-for-profit, non-governmental organization whose purpose is to provide national advice on issues relating to biomedical science, medicine, and health, and to serve as adviser to the nation to improve health, defines healthcare quality as the â€Å"degree to which health services for individuals and populations increase the likelihood of desired health outcomes and are consistent with current professional knowledge. à ¢â‚¬  (Retrieved July 11, 2009 from http://www. iom. edu). Further expounding the definitions provided, the IOM developed six dimensions of quality healthcare: 1. Timeliness – refers to the length of time it takes to provide care to patients. For example, how long it takes a patient to receive a treatment or follow-up care once a breast mass is detected. Delays should be shortened to increase the efficacy of treatments and to ease the patient’s fears. 2. Safety – refers to the ability or need to avoid injuries that result from the provided care that is intended to help the patient. Injuries such as those resulting from administering the wrong drug or wrong dosage, incorrect diagnoses, etc. 3. Effectiveness – the extent to which healthcare service is provided based on scientific knowledge to all who could benefit and refraining from providing services to those not likely to benefit, that is avoiding over-and underuse of resources. 4. Equity – the extent to which quality care is provided without regards to a patient’s gender, geographic location, gender and socioeconomic status. 5. Efficiency – the extent to which equipment, supplies and energy waste is avoided. 6. Patient-Centeredness – the extent to which the patient’s preferences, values and needs are taken into account when providing healthcare service. Care should be provided respectful of and responsive to the patient. Comparatively, in his book An Introduction to Quality Assurance in Health Care, Avedis Donabedian provides seven components of what he considers quality in health care. Three of these components are included in the IOMs dimension of quality healthcare; effectiveness, efficiency and equity. The remaining four are: 1. Efficacy – the extent to which healthcare technology and science are able to bring about health improvements when used under the most ideal circumstances. 2. Optimality – balancing the cost of healthcare improvements against the actual improvements, or in other words, by use of cost/benefit analysis ensuring that costs are not incurred which do not result in benefits do not exceed the cost or investment required. 3. Acceptability – the extent to which the expectations, desires and wishes of the patient and responsible members of their families are conformed to. There are five parts to the development of this definition: ? Accessibility – the ease with which patients can obtain healthcare ? The patient-provider relationship – the extent to which the healthcare provider exhibits towards the patient personal concern, good manners, honesty, truthfulness, attention to the preferences of the patients, making efforts to provide explanations, patience, empathy, respectfulness and the avoidance of condescension. ? Amenities of care – the desirable aspects of the circumstances and/or environment under which healthcare is provided and includes cleanliness, adequate parking, convenience, privacy, comfort, restfulness, availability of refreshments, good food, etc. Patient preferences regarding the risks, cost and effects of care – recognition that the patient’s value of the consequences of care may differ for that of the healthcare provider and from patient to patient. Healthcare providers should take the time to explain to the patient the expected cost, risk and effects of alternatives and be guided by the informed opinions of the patients or responsibl e family member. ? Patient’s definition of fair and equitable As initially mentioned there are various legitimate definitions of what constitutes healthcare quality. In developing this research paper, each of the definitions above will be utilized to address the issue of improving healthcare quality. The State of Quality Healthcare Surveys show growing concern over the eroding performance of the health care system. In November of 1999, the Institute of Medicine released a report entitled To Err Is Human: Building a Safer Health System, which concluded that 44,000 to 98,000 people die each year in hospitals due to preventable medical errors. In 2003 The National Committee for Quality Assurance (NCQA) released their first annual State of Healthcare Quality eport which found: More than 57,000 Americans die needlessly each year because they do not receive appropriate health care. The majority, almost 50,000 die because known conditions – high blood pressure or elevated cholesterol – are not adequately monitored and controlled. Others die or are at increased risk of death because they have not received the right preventative or follow-up care. [This is because] people with high blood pressure do not have it controlled, . . . people who have suffered a heart do not have their cholesterol levels monitored . . . and] smokers receive no advice to quit. Put simply, the healthcare system regularly fails to deliver care we know to be appropriate. (Nash Goldfarb (2006) p 7-8) Although quality improvements have been made in some areas since that first report, the NCQA’s 2007 report illustrated significant room for improvement. In the area of medication management and prescription, the report found inappropriate use of some treatment medications, specifically antibiotics. Americans suffer an estimated one billion upper respiratory infections or common colds annually. Colds are especially common among children, who suffer approximately three to eight colds a year. Because the common cold is most often viral, existing clinical guidelines do not prescribe the use of antibiotics as a treatment measure. Nevertheless, antibiotics are frequently prescribed to children with colds. Complications ranging from fevers and rashes to drug allergies, prolonged hospital stays and even death often arise from antibiotic treatment. Additionally, inappropriate antibiotic use contributes to bacterial resistance to antibiotics and represents wasted health care resources. Annually $227 million is spent for inappropriate treatment for the common cold. The impact upon the elderly is just as damaging. Despite medical consensus that certain medications increase the risk of adverse effects to the elderly and should generally be avoided, these medications are still often prescribed to the elderly. One in 20 prescriptions filled by the elderly are for drugs deemed as â€Å"always avoid†. More than 1 in 10 filled prescriptions are for drugs that would rarely be considered appropriate. Studies show that 21 to 37 percent of elderly patients had prescriptions filled for at least one potentially inappropriate drug and more than 15 percent had filled at least two. More than 40 percent of serious, life-threatening or fatal adverse drug events and 80 percent of adverse drug events in the elderly are avoidable. One study found that almost 3 percent of all elderly patients in a managed care organization suffered a preventable adverse drug event in a year. Reducing the number of inappropriate prescriptions can lead to improved patient safety and significant cost savings. Conservative estimates of extra costs due to potentially inappropriate medications in the elderly average $7. 2 billion a year. The 2007 State of Healthcare Quality report found in total between 38,300 and 88,900 avoidable deaths due to unexplained variations in care and avoidable hospital costs between $1. 9 and $3. 5 billion. Additionally, the report determined an estimated 51. 6 million avoidable sick days due to unexplained variation in care at a cost of lost productivity of approximately $8. 5 billion. These findings alone suggests and supports the employment of continuous improvement measures in the quality of healthcare. Quality Indicators â€Å"In health care as in other arenas, that which cannot be measured is difficult to improve. Providers, consumers, policy makers, and others seeking to improve the quality of health care need accessible, reliable indicators of quality that they can use to flag potential problems, follow trends over time, and identify disparities across regions, communities, and providers. (Guide to Prevention Quality Indicators: Hospital Admission for Ambulatory Care Sensitive Conditions, 2007, p 4) There are a number of measures that have been developed or defined by various organizations, measures that are utilized to determine, adjust and/or improve healthcare quality. One such organization has developed and implemented quality indicators (QI) to assist providers, policy makers, and researchers in the analysis of data to identify variations in the qualit y of either inpatient or outpatient care; the Department of Health and Human Services Agency for Healthcare Research and Quality (AHRQ). The AHRQ’s aim is to improve the quality, safety, efficiency and effectiveness of healthcare and does so through researching: quality improvement and patient safety, outcomes and effectiveness of care, clinical practice and technology assessment, health care organization and delivery systems, primary care including preventive services, healthcare costs and sources of payment. The indicators defined by the AHRQ are used to measure various aspects of health care quality based upon hospital administrative data. The quality ndicators or QIs are grouped into four modules: ? Prevention Quality Indicators (PQI) – used to identify ambulatory care sensitive conditions (ACSC) which are â€Å"preventable hospitalizations† or conditions for which good outpatient care can potentially prevent the need for hospitalization, or for which early intervention can prevent complications or more severe disease. Despite these indicators being based upon hospital inpatient data, PQIs pro vide insight into the quality of healthcare outside the hospital setting. For example, a diabetic patient may be hospitalized for complications associated with diabetes if their condition is not sufficiently monitored, if they do not receive proper patient education or if they do not manage their condition. Even though other factors outside of the healthcare system may result in hospitalization such as patient failure to follow treatment recommendations, or poor environmental conditions, PQIs are a good beginning point for assessing the quality of healthcare within a community and â€Å"serve as a screening tool rather than as definitive measures of quality problems. They can provide initial information about potential problems in the community that may require further, more in-depth analysis. † (AHQR, (2007), p 2) Despite the strengths of these indicators, there are a few weaknesses that should be considered. First, differences in socioeconomic status have been shown to explain a large part of the variation in some PQI rates across areas. The intricacy of the relationship between socioeconomic status and PQI rates makes it difficult to delineate how much of the relationships are due to true difficulties in access to care in potentially underserved populations, or due to other characteristics, unrelated to quality of care, that vary by socioeconomic status. â€Å"For some of the indicators, patient preferences and hospital capabilities for inpatient or outpatient care might explain variations in hospitalizations. In addition, environmental conditions that are not under the direct control of the health care system can substantially influence some of the PQIs. For example, the COPD and asthma admission rates are likely to be higher in areas with poorer air quality. † (AHRQ, p 17). Second, the question of whether effective treatments in outpatient settings would reduce the overall incidence of hospitalizations has not been adequately addressed. The degree to which the reporting of admission rates for ACSC may result in changes in ambulatory practices and admission rates also is unknown. Patients may be admitted who do not clinically require inpatient care or patient may not be admitted who would benefit from inpatient care. Inpatient Quality Indicators (IQI) reflect quality of care inside hospitals including inpatient mortality for medical conditions and surgical procedures and comprises three types of measures: ? Volume Measures are indirect measures of quality based upon evidence suggesting that hospitals performing more of selected inpatient procedures may have better outcomes for those procedures. Volume indicators shows the numb er of admissions in which these procedures were performed. ? In-hospital mortality indicators measure death rates for selected common surgical procedures or medical conditions. Utilization indicators focus on the volume of selected procedures for which research has suggested issues of overuse, underuse, or misuse. The weakeness of these indicators is that they are based upon data which is collected for billing pruposes and not research or measuring quailty. Dispite the insight that may be offered from these indicators, they should not be used as a decisive source of information on the quality of health care. At least three limitations of administrative data warrant caution: ? Coding differences across hospitals. Some hospitals code more thoroughly than others, making â€Å"fair† comparisons across hospitals difficult. ? Ambiguity about when a condition occurs. Most administrative data cannot distinguish unambiguously whether a specific condition was present at admission or whether it occurred during the stay (i. e. , a possible complication). ? Limitations in ICD-9-CM coding. The codes themselves are often not specific enough to adequately characterize a patient’s condition, which makes it impossible to perfectly risk-adjust any administrative data set, thus fair comparisons across hospitals become difficult. In short, the AHRQ IQIs are a valuable tool that takes advantage of readily available data to flag potential quality-of-care problems. (AHRQ, 2007, p 18) ? Patient Safety Indicators (PSI) measures harm or adverse effects resulting from healthcare services. These indicators are defined on two levels; provider level indicators which measure preventable ill effects by patients who received care and the adverse effects within the same hospitalization, and area level indicators. Area level indicators measures all cases of preventable ill effects that occurred within a specific area. Pediatric Quality Indicators (PDI) like PSIs include provider level and area level indicators to identify potentially preventable complications but as they apply to pediatric patients, that is those under the age of 18 years. The measures and indicators developed by AHRQ are not exclusive nor do any of the indicators alone provide a complete quality assessment of healthcare systems. However, these QIs take adv antage of existing data and data collections systems in place in order to develop areas of improvement and some bases of comparison between healthcare organizations, standards, benchmarks, etc. Once areas of improvement have been identified by QI, the job of addressing those identified shortcomings may begin. Methods abound which addresses improving quality, such as Six Sigma, Total Quality Management, etc.. These may be employed within a healthcare setting with as much success as doing so in a manufacturing plant. Conclusion This paper sought to examine one side of the healthcare triad, quality. The other two being cost and access. However, by no means should one presume that quality or any of the three is more critical than the other. In fact, improving healthcare quality will effect the cost of healthcare, which in turn will effect access to that quality healthcare. Just as, effecting cost will impact quality and access. Admittedly, this paper fails to address in detail the intricate relationship between these three factors – but acknowledges the existence of this relationship. Improving quality requires a clear definition of â€Å"health care quality† . Ideally, this definition is based upon identifiable and measurable scientific indicators but without disregarding other indicators such as patient satisfaction. Once a definition has been formulated, indicators or measures may be developed and employed to identify areas of improvement and to then address those short falls in quality. References Beers, M. H.

Transesterification Fossil Oils into Biodiesel

Question: Discuss about the Transesterification for Fossil Oils into Biodiesel? Answer: Introduction Transesterification is the process to convert the fossil oils into Biodiesel. Biodiesel and fossil diesel are fall into same category of fuel. It is produced from straight vegetable oil, waste cooking oil , animal fats and tallow. Biodiesel transesterification represents the heart of any biodiesel manufacturing plant. It involves various complex set of chemical actions and heat transfer mechanism. There are several reactors which performs these operations. Each of the factors has their own advantages and disadvantages. In manufacturing unit the continuous transesterification is more preferable than batch processes. Because, the contineus processes give product quality, low capital and low operating costs per unit. The continuous stirred-tank reactors are the most popular continuous flow reactors in the manufacturing sectors. The primary objective of this report is to design and prototype a transesterification reactor to convert canola oil to biodiesel Furthermore, this report design a heat exchanger, storage tank and pump including the technical design as well as decision on the controls to use and instrumentation. Section 1 Process description: Once sodium hydroxide dissolved in methanol to make methoxideand react with canola oilthat pumped from the storage tank passes through heat exchanger into the reactor as the transesterification reaction occurs at condition 60and 4 bar. In the process of transesterification the reaction of lipid and alcohol forms esters and a byproduct namely glycerol. On the other hand the process displaces one alcohol from an ester. This process is called alcoholysis. This reaction is reversible and as a result of this an excess of alcohol forces the equilibrium in product side. The ratio of alcohol to lipid in the equilibrium is 3:1. However, this is increased to 6:1 to increase the product yield. The transesterification procedure has of three phases. The first step is the conversion of triglycerides to diglycerides, the next phase represents the transform of diglycerides into monoglycerides, and finally the last phase puts monoglycerides into glycerol. Each step yields one ester molecule from each glyceride. The reactions are reversible. The equilibrium helps to produce glycerol and fatty acid esters. Section 2 Storage Tank: The storage tank is used to store pure conola oil. The tank loads various discharged material by the transporters.Since moist increase spoilage risk tank must be protected from atmospheric moisture as moisture raises enzymatic and biological activity that leads to mold growth(Canada, 2003). The tank must be heated enough to prevent freezing. Flow diagram Construction material: Schweitzer, 1991recommends the carbon steel must be used in 25C and canona fluid must be added in the process. Because, the corrosion of these materials are less. PID Sizing: The size of the oil storage tank is determined using the above mentioned relations and is as represented in the table (E.1) Cost of the tank Section 3 Heat exchanger: The heat exchanger used in this section of biodiesel process will be selected here. In choosing the heat exchangers, various factors should be considered for each application. These factors include operating temperatures of the exchanger, fouling, pressure and pressure drop of the exchanger, utility stream characteristics, process stream and capital cost of the operation. These factors play important role in selecting the best heat exchanger. Table (6.18) represents the applicability of different heat exchangers [Van Den Berg , 2000]. Type Advantages Disadvantages Operating ranges Tube and Shell Flexible procedure, robust and easy to maintain Sometimes not economical for low pressure Tube-side 1400 bar Shell side 300 bar -270C to 1600C Air cooler Larger heat loads, Free utility ( air ) Economical for process fluid at low temperature 470 bar, process fluid up to 500c Double pipe High pressures possible , cheap construction, easy to maintain Poor heat transfer coefficient expensive for large duties Tube-side 1400 bar and 100-160 c Frame and Plate Lower areas needed, High effectiveness factor, compact Not appropriate for carbon stell, limited to below 30 bar 30 bar and -40 to 170c The above table shows that the tube and shell exchanger is the most suitable in this context. The next decision is to be taken after the selection of shell and tube heat exchangers is the necessary fluid required on tube side or on shell side. The table shown below represents few measures for the fluid allocation. Factors Solution Fouling When the fouling fluid on tube side, the fouling is reduced by higher available velocity Temperature On the tube side hottest liquid is placed on the tube construction more expensive material is placed Operating pressure The fluid with high-pressure is placed on tube side high pressure shell is more expensive than high pressure tube Pressure drop Fluid with lowest variation in temperature should be allocated to tube side where it gets highest heat transfer coefficient. Construction material Carbon steel PID Control of heat exchanger: The most equipment configuration of heat exchangers are shown above. The utility stream flow rate controls the product outlet stream temperature. So, by controlling utility flow rate the output temperature can be monitored. The above table shows how the free forward control is applied considering the flow to the exchanger at cascade outlet temperature Design Procedure : The amount of heat transfer across a surface is given by the below mentioned equation: Determining the surface area required for the specified duty with the available temperature difference is the primary importance of the design of the exchanger. The heat coefficient is measured by the equation as mentioned below: The dimensions of the reactor vessel are determined in regards of the above mentioned equation, and the results are shown the table below: Section 4 Pumps : Pumps can be classified into two categories. These are dynamic pumps and positive displacement pumps. The example of dynamic pump is centrifugal pump whereas, the example of positive displacement pump is reciprocating and diaphragm pumps. The major benefits of centrifugal pumps are as mentioned below (Peters and Timmerhaus, 1991): - The pumps are cheap and have simple constructional structure - The pumps are useful for liquid with large amount of solids à ¢Ã¢â€š ¬Ã‚ ¨ - costs of Maintenance of these pumps are much lower than those of other pumps. Miscellaneous Pressure Losses: The turbulence is generated by obstruction in the flow. So, the process of pipe fitting drops the pressure of pipeline the process creates turbulence by bends, eklbows , reduction or enlargement of sections etc. Construction material Flow diagram Control of Pumps: The rate of flow of the pumped streams are regulated to get a specific amount of pressure of streams. This stream enters into the reactor and exists from the reactor in the process of pumping. The pumps are designed to be operated under constant speed. There are pumps of various variable speeds. But, these pumps are very expensive. Apart from this, the pump control system ranges from single hand-operated pumps to various highly advanced pumps like automatic flow control, pump speed control etc. The factors important for control system choice are pump type and drive type. Such as in centrifugal pump by changing either the speed or the valve setting the output can be controlled. PID Pump sizing Section 5 Reactor Design: A general reactor design procedure is outlined below: Collect the thermodynamic and kinetic data based on the side reactions and desired reaction. Collect the data of physical property which are required for the design Identify the predominant mechanism for rate controlling: Kinetic, mass or heat transfer. Make an initial selection of the conditions of reactor to give the desired yield and conversion. Estimate its performance after sizing the reactor. Select material suitable for construction create preliminary mechanical design for the reactor. Cost the proposed design, capital and operating. Transesterification Process: The final step of obtaining Fatty Acid Methyl Ester (FAME) by reacting with alcohol such as methanol and Ethanol with triglyceride molecules is knows as transesterification. For transesterification process , an alkaline catalyst NaOH ( sodium hydroxide) to elevate the reaction at STP and to produce FAME and glycerol after step by step conversion as shown below. [7] Figure 1: Transesterification Process Transesterification term represents the important class of organic reactions whereas, an ester of represent the transfer into another through interchange of the alkoxy moiety. The transesterification process is called alcoholysis when the original ester does chemical reaction with an alcohol,. Various industrial process use the Transesterification Process. This reaction happens by the mixture of reactants and it is an equilibrium reaction. The catalyst accelerates the reaction and increases the temperature. To obtain the high amount of esters the alcohol ahs to be used in excess amount. In the presence of alcohol and a catalyst with glycerol, the reaction transforms the transforming triglyceride into fatty acid alkyl esters. The stoichiometric ratio of the reaction is 6:1. The reaction is inherently endothermic. The overall reaction scheme can be shown below: Type of reactor: Three are batch reactors, semi continuous flow reactors and continuous flow reactors are three types of reactors are used in biodiesel production. The batch process is cost effective. It requires much less initial capital and investment in infrastructure. The process is flexible. Variations in feedstock type, composition and quantity are available in this process. Low productivity, more intensive labor, larger variation in product quality and energy requirements are major drawbacks of this process. The batch process and semi continuous process are similar in most of the aspects except in the one case. In this process the producer starts the reaction in lesser volume than the vessel can hold and then continues to add ingredients until it is full. Continuous-stirred Tank Reactor (CSTR) will be used in this purpose. In CSTR, any materials is easy and free to enter and exit. The conditions do not change with time which will make our process conditions constant and not always changing which is easier to handle and control.The productsare removed continuously and the reactants are entered into the reactor continuously.The conditions of entering and exit streams are the same. CSTR are well mixed, the contents have uniform and equal properties such as the temperature, densityand pressure. The volume of CSTR are usually at constant volume. There are stirrers called agitators inside CSTR to mix well the reactants and catalyst. A CSTR can act as loop reactor when heated. The pressurized fluid is inserted into the system to facilitate the stirring or the agitators for higher heat and mass transfer rates. Design Methods of Chemical Engineering The Kinetics The Table 2.6 represents the set of transesterification reactions considering the simulation of the primary transesterification reactor. The In the Table 2.8 it is showing the values of rate constant and the equilibrium constant. The two factors limit the reactor temperature and controls it to not go beyond a certain limit. These are the instability of the evaporation and the increased rate of byproducts formation. Configuration of Reactor: For the transesterification reaction a jacketed continuously stirred tank reactor is appropriate. It is required to operate it continuously for 8150 hours per day. The reactor helps to operate the transesterification reactions and helps the suspension of finely suspended solids. This process creates suspension by agitation. As recommended by Bassel, (1990), the ratio between the height of the liquid and the diameter of the reactor is 2:1. The reactor must be 90% full. The heating efficiency of the reactors must be adjusted properly to attain reaction times and short heating. The care should in the whole operation as the jacket is joined with the heating tube across its length. Construction material: The constructional material consists of three portions. These are the vessel of the reactor, Jacket of the reactor and reactor agitator. The vessel of Reactor: The reactor vessel in the process of transesterification process must be kept under 60c temperature and moderate pressure. Schweitzer, 1991, and Hermann Ludewig, 1971 has recommended to use the stainless steel 316 for construction of this vessel Jacket of Reactor: According to Hermann Ludewig, 1971, the use of carbon steel must be used when the water heating is required. Reactor agitator : According to Hermann Ludewig, 1971, high-grade steel must be used as some corrosive reactant. Stainless steel 316 is best for this purpose. Size of the reactor: The mixing intensity represents the amount and proportion of mixing of alcohol and triglyceride (TG) in the reaction. The phases of the mixing are very important. In most of the cases the mechanical mixing procedure is followed to fasten the reaction process and increase the contact between the particles. This process increases the transfer arte of the mass. This procedure has its origin in the eighties. Thus the variation in mixing intensities in the reaction can change the kinetics of the transesterification reaction.The Rqynolds number helps to access the mixing intensity. In the fluid dynamics, the ratio of inertial forces to viscous forces is represented by NRe (dimensionless number) in fluid dynamics. The following equation represents the NRe. Here n represents the rotational speed of the impeller, Da represents the impeller diameter, and and represent the fluid density and viscosity. Noureddini and his team investigated on the effect of Reynolds number on the transesterification reactions. The reactor is sized using the previous relations, and the Table (E.1) summarizes the results of the sizing of the reactor. Mixer design: The mixer design represents the type of mixer to be selected. The selection is done according to the guidelines specified of Ulrich, 1984. The measurements of the agitation system should be as specification provided in the guidelines by Geankopolis, 1993,pp. 144. Jacket selection The factors considered to select the type of jacket are as mentioned below: - The Cost à ¢Ã¢â€š ¬Ã‚ ¨ - The heat transfer rate à ¢Ã¢â€š ¬Ã‚ ¨ - The Pressure à ¢Ã¢â€š ¬Ã‚ ¨ The table below represents various jacket types and their characteristics considering these above mentioned three factors, Coulson and Richardson, 1999. à ¢Ã¢â€š ¬Ã‚ ¨ Type Remarks Spirally and baffled jackets High heat transfer rate. Dimple jacket Used up to 20 bar. Simple and not baffled Lowest cost and used up to 10 bar. Half pipe jacket High heat transfer rate, and used for high pressures up to 70 bar. The jacket is sized by the some relations, and the results of jacket summarizes in Table (E.1) summarizes Vessel support design: The vessel support method requires to consider below mentioned factors: The shape, size of the vessel and weight of the vessel, à ¢Ã¢â€š ¬Ã‚ ¨ To design the temperature and pressure of the vessel.à ¢Ã¢â€š ¬Ã‚ ¨ Vessel location and arrangement à ¢Ã¢â€š ¬Ã‚ ¨ The fittings of internal and external portion of the vessel and attachments.à ¢Ã¢â€š ¬Ã‚ ¨ The table shown below represents the various supports and their characteristics, Coulson and Richardson, 1999. Support types Remarks Skirt Appropriate for vertical columns Saddle Appropriate for horizontal vessels A skirt, in cylindrical shape, made of plain carbon steel is used to support the reactor and the highest dead weight load occurs when the vessel is full. Control of reactor: Because the process is continuing. The feed of the reactor needs to be constant within certain limits. The feed consists of two main components: oil and methanolxide. The methnoaloxide stream is kept constant and is measured by a flow control acting on a valve in the feed stream. A flow constant is attached and acts on the input of the amount of oil. The amount of the methanoxide and oil are now fed in the right amounts to get the desired ratio in the reactor. Also, the reaction is endothermic and quite an amount of heat is needed but the temperature must be continuously kept at 60c. the amount of heat needed is controlled by a temperature controller. The reactor controlled by a level controller which acts on a valve attached to the outgoing stream. This done to ensure the residence time in the reactor. Startup and shutdown Considering the above mentioned factors , the Transesterification reactor start-up needs to consider three things. These are as getting ambient temperature to steady operating temperature. Setting the process flow rates from zero to their steady state values and controlling the operation to reach the desired equilibrium state rate. Similarly the shutting down involves to stop the flow and to let the ambient temperature to cool down. But, sometimes stopping the reactant flow into the system, without controlling other important aspects, can lead to the explosion. So, the shut down process as well as the start up process requires detailed thought, planning and analysis. Cost of the reactor Section 6 Utilities: The biodiesel plant makes use of different utilities such us steam, water and electricity. Most of the steam is low pressure steam. Reason for selection and other options: The heating processes uses steam and the cooling is carried out by air and cooling water. All electricity is produced outside battery lirnits, no steam is used in the design to generate power. Further it isn't necessary to use a refrigerant to cool or condense any one of the streams. Major users The pieces of equipment using a lot of electricity are reactor, heat exchanger and pump. These three instruments together use almost 23% of the total electricity consumption of the plant. The major users of steam are heat exchangers and users of water is jacket of the reactor. Possibilities of future reduction: Heat integration is a part of the design which isn't applied. There are great opportunities to reduce the consumption of utilities by heat integration. Section 7: Hazard and Operability Analysis (HAZOP): The Hazard and Operability Analysis (HAZOP) identifies hazard and operability problems of the industry. It investigates the deviation of the operation of the plants from the intended design. The HAZOP result represents the inevitable problems occur in the course of production. The main aspect of HAZOP problem is to identify the problems and the firm should not dwell on the problems which are not apparent in the analysis. HAZOP is concerned about the safely of the operation and hazards represents the operational problems which degrades the performance of the plant. It also affects the product quality, production rate nad profit. Hence, the insights of individual engineers who work in the plant is very important to make the overall efficiency of the plant high. In the present discussion, the main trancesterification reaction was chosen as the subject of HAZOPs study. The reason for is the importance of the reaction in the Biodiesel plant. To measure the intensity and probability of hazardous operation a Hazard Matrix was created. To analyze the hazardous effects of unit operation few factors have been chosen. These factors are flows, pressure, and temperature of the reactor. These factors determine the possible deviation which could lead to definitive hazards the possible causes, consequences for each deviation has been identified and the researcher also provided the recommendation for each aspect. The matrix is shown below.

Policy Profile Of Senator Richard Lugar The Following Report Will Atte

Policy Profile of Senator Richard Lugar The following report will attempt to provide a brief, yet concise policy profile of Indiana Republican Senator Richard Lugar. Beginning with a short biographical review, the profile will proceed and concentrate on Senator Lugar's major areas of public policy concern; Foreign Affairs, Agriculture, and in part, his 1996 Presidential Campaign which encompasses a myriad of issues, both foreign and domestic. It would be impossible to include every aspect of Senator Lugar's political career and personal life within the scope of this paper. Instead, emphasis will be placed on the most important and critical points of his tenure in American politics, at the federal level. However, in the conclusion of this text a rational explanation will be offered to give insight concerning Senator Lugar's motivations and tendencies to act in the way he does. Biographical Background Richard Green Lugar was born in Indianapolis, Indiana, on April 4, 1932. Attending Sh ortridge High School he excelled academically and was the class Valedictorian. After graduation, Dick Lugar (as he is commonly known) attended Denison University, in Ohio, and met his future wife Charlene Smeltzer. In 1954 Lugar received his degree from Denison and went on to be a Rhodes Scholar at Pembroke College on the campus of Oxford University, in England. Richard and Charlene were married in September, 1956, and now have four sons and six grandchildren. After completing studies at Oxford, Dick Lugar went to the American Embassy in London, England and promptly enlisted in the Navy as an intelligence briefer and was responsible for giving intelligence reports to 'high brass', including the President of the United States, Dwight D. Eisenhower. Along with Senator Lugar's political achievements, he has occupied positions in the private sector, as well as a stint in the United States Navy. As a young man Richard Lugar worked at, and managed the family businesses, a farm, and a food machinery firm started by his Grandfather over 100 years ago, Thomas L. Green Both are located in the Indianapolis area. In 1964, Lugar obtained his first political office with the Indianapolis School Board. He then went on to win the Mayoral bid in 1968, and served two terms at the head of city government in Indianapolis. Senator Lugar's next stepping stone in politics would be a failed attempt for the office of United States Senator in 1974, losing to incumbent Birch Bayh, father of the current Indiana Governor, Evan Bayh. Suprisingly, Lugar lost the election by only 75,000 votes, quite an accomplishment considering the incumbency factor. Lugar ran for the Senate again in 1976 and captured the seat from Democratic incumbent Vance Hartke. Senator Lugar has since been reelected two times (in 1988, he won by an overwhelming 68% percent of the total vote) and is currently in the midst of a campaign for President of the United States where he faces eight other challengers for the Repu blican nomination. Other achievements by Lugar that are worth mentioning are: His selection to the vice-presidency of the National League of Cities in 1970. He was appointed chairman, of the Republican Senatorial Campaign Committee for the 98th Congress. Served as chairman for the Senate Committee on Foreign Relations from 1985 to 1987. He is currently the chairman of the Senate Committee on Agriculture, Nutrition, and Forestry. Senator Lugar also serves on the Senate Select Intelligence Committee, and Foreign Affairs sub-committees; Western Hemisphere and Peace Corps Affairs, International Economic Policy, East Asian and Pacific Affairs, Trade, Oceans and Environment. (101st, 486-489; 102nd,485-488; Directory,1399; Miller, 95') Foreign Affairs Senator Richard Lugar is acknowledged to be one of the pre-eminent national leaders in the realm of foreign policy. Some have even claimed that he is in reality a "shadow Secretary of State", being recognized around the globe for his involvem ent with international politics. Lugar's involvement and membership to key Senate Foreign Affairs sub-committees, and being the chair of the full committee for one session of Congress shows his willingness and diligence to be involved in this policy area. Note, however, Senator Lugar was forced out of the chairmanship and did not voluntarily leave. (101st Congress, 486) Lugar has four principle premises for good foreign policy. They are as follows:

Essay on Several Different Papers part 3Essay Writing Service Essay on Several Different Papers part 3 Essay on Several Different Papers part 3Essay on Several Different Papers part 2Week 7 Decision making processThe decision making process is very important for the successful business development but often this process confronts substantial challenges, especially when family members come into business together and fail to decide their responsibilities and determine the essence of the decision making process. In this regard, referring to the case of the retail clothing store, run along with a family member, it is possible to recommend to determine exactly how decisions are made within the company and who exactly takes what decisions.First of all, the decision making process should be collective that means that both family members take decisions. However, their authority should not overlap that means that they should take decisions on different issues. For instance, one family member is responsible for suppliers and delivery of products to the clothing store, while another is responsib le for sales, human resources and public relations of the company (Masterson Picton, 2004). In such a way, they should distribute different areas of their responsibility between each other. Thus, both family members will participate in the decision making process and will play an important part in this process. At the same time, such decision making model will be effective because family members will distribute their functions and will focus on their specific fields (Breneman Taylor, 2006). As a result, they will not waste their time and efforts on other fields that will maximize their effectives in those areas, which they are responsible for.On the other hand, such decision making model will decrease the risk of conflicts. As each family member is responsible for his/her fields only, then they do not intersect and they do not have the pretext and cause for the conflict. They just concentrate on their own work and decisions.Nevertheless, the proposed model does not mean that there will be no conflicts at all. On the contrary, conflicts still are likely to occur because they comprise a natural part of any business. In such a situation, the prevention of conflicts is particularly important because conflicts can deteriorate the organizational performance. The conflict prevention and resolution should involve consultations between the two family members. What is meant here is the fact that they should find consensus to take the right decision that meets the vision of each family member. They should learn to compromise to make effective and fast decisions. For instance, if family members face a conflict over funding of the new promotional campaign or singing a contract with a new supplier, they should weigh both options and select the one that matches the current needs of the company, its mission, vision and marketing strategy. Therefore, if the company lacks supplies, the new supplier should be signed, while if the company has low sale rates, the company should rather invest into the promotion of its products and brand.Thus, the conflict prevention is very important, while the resolution of conflicts should involve the close interaction and communication between both family members running the store. In this regard, the distribution of responsibilities and functions and, therefore, decision making processes will decrease the risk of conflicts and help the company to develop successfully.

Hospitality as a performance Essay Example | Topics and Well Written Essays - 3000 words

Hospitality as a performance - Essay Example For, in the hospitality industry, there are no takes or retakes; once performed, there in no turning back. This makes the job of these personnel extremely difficult and mentally tough. We see that one often needs to present themselves in different ways in varying situations. The front office men and women are well-dressed and offer a glowing countenance every time a customer walks up to them, whether they like or not. A bartender may not be having the best of days, yet he/she will have to offer the kindest smile in the world, every time a stranger asks for a drink. A waiter or waitress may be having the worst day in their life, still they offer a towel or remark politely, " Its OK Sir, I'll have it cleaned up immediately," when a customer throws up or spills a drink over the table. Welcome then to the hospitality industry, where all sorts of roles are played out day-in, day-out to keep their customers happy. Most often, these roles come with a script, a fixed message. Considering the magnitude of personal involvement, the pressure to perform remains utmost important in organisations such as the hospitality and other service industries. Organisational Behaviour in Hotels and Restaurants are monitored to such an extent that unless the personnel perform to industry standards, they are most likely to lose business and name. Personal relations remain high on their agenda. A study of the industry suggests that performance is based on strong HR policies. One could study the following to understand the impact of personal supervision to understand the following: Why is it a work in some organisations pleasurable, and torturous in others Why is it difficult to motivate employees to work hard How can one person persuade a group to work as a team Which is the best way of designing an organisational structure Can one persuade his/her boss to listen to their ideas (Guerrier, 2004). Motivation remains the biggest factor in making people perform. One can never get away from the fact that, man has and will continue to be fascinated by rewards and appreciation. Many hotels have come forward to openly recognize the best performer in the various departments of their hotel to encourage others to perform. Hotel personnel are stage performers, and to get the best out of them, there is nothing like showing the bait. 'Role playing' is what is enacted by these personnel right through their career in the hotel. The same may not be the case in real life, as their life at home or with friends. Similarly, Gorden Rumsay runs a program called, 'hell kitchen.' For outsiders, the feeling may be one of terror or bullish. He wants to be a perfectionist, and goes about shouting and screaming at his staff, with the occasional use of four-letter words to get his staff to perform. This may be his way to get the best from his staff. However, his staff and others around him may think of h im to be arrogant and

The Future of the Chinese Communist Party Essay Example | Topics and Well Written Essays - 500 words

The Future of the Chinese Communist Party - Essay Example The essay "The Future of the Chinese Communist Party" analyzes the future of the Chinese Communist Party that faces a major hurdle of the unresolved tension between the economic and political reforms. Though the party still maintains extensive political power with an aim of exercising its controls in the major sectors in the country. If the state wants to ensure that the policies that it pledged at the Plenum come to a realization, it must reduce its role. Schuman observes that a well-functioning economic system must have banks that function properly, for instance, the government must set clear lending decisions. State corporations must operate within the healthy political framework away from political interferences to allow for the flourishing of the private sector. David Shambaugh observes that the C.C.P needs to encourage particular policies that promote competition such as liberalization of prizes. Such policies would mean that the politicians sit back and observe how the market regulates resources. Zhao et al. note the rising tussle between the economic reformists and the authoritarian party leaders leads to some of the fatal problems noted by Barmà ©. If CCP is to succeed, it must let go of the reins of control in areas where it  is not welcome. The second challenge facing the party is the lack of accountability on sensitive issues that face its people. There are several occurrences that emphasize on this point as observed in the communist country. Among the grievances is the prevalence of income inequality.

Fed Undertakes QE3 with $40 Billion Monthly Mortgage Backed Securities Assignment

Fed Undertakes QE3 with $40 Billion Monthly Mortgage Backed Securities Purchase - Assignment Example My understanding is that the essay seeks to address the purchase of mortgage securities by the Fed; therefore the reason behind this purchase should come out before how the purchase was undertaken. The economic meltdown should first be explained, followed by the initial two quantitative easing programs and finally the QE3. The effects of the QE3 should then be addressed thereafter. The reasons behind the failure of the previous two QEs should also be stated so that the factors that led to the undertaking of the QE3 can be clearly illustrated. The essay should be a roadmap leading the reader to an inevitable conclusion, not properly ordering your ideas could obscure the meaning of the essay. After reading the essay, one can clearly see the efforts of the Fed in jump starting the economy after the economic downturn and that these efforts seem to be finally working. The paper however leaves one with the question of whether the Fed’s undertaking will work in the long run. Although the program has proved to be fruitful since its announcement, the QE3’s limitations and misgivings should also be included in the essay. In this aspect, the paper does not seem to be complete, as the aftermath of the program, both in the short term and long term, is an area that could be expanded upon. Although the essay is persuasive as it is detailed, the source of the information is not given, which brings about doubt as to the accuracy of this information due to the lack of evidence. The works cited during the writing of the paper should be stated at the end of the

Bell Hooks Class Matter Essay Example | Topics and Well Written Essays - 750 words

Bell Hooks Class Matter - Essay Example Regardless of these movements, classism continues to exist in society and many authors are trying to create awareness by discussing the topic. This essay analyses classism in contemporary America as discussed by Bell Hooks in her novel, ‘Where We Stand: Class Matters’. The essay has further discussed measures that can be taken to counter socioeconomic oppression that is brought about by classism. Bell Hooks discusses the theme of classism in contemporary America by addressing issues concerning racism, gender and white-supremacist ideologies. Hooks introduces the book by discussing her poor upbringing. Her story is that of transformation from modest roots upper class echelons. Through Hooks’ biographical narrative, we are able to comprehend her beliefs concerning racism, classism and gender bias. Classism is a dominant theme through the novel, and has been highlighted by racism since racism is used in society to propagate classism. In contemporary America, whites are generally of a higher class while African-Americans and other non-whites are generally considered of being of a low class. Hooks discusses how whites from various classes try their best to assist African –Americans and non-whites of a lower class so that they are able to maintain the status quo (Mahony & Zmroczek 46). Gender has been discussed by the author in association with the theme of classism. Hooks has explained the role that gender has played in the society in various capacities. In her initial tale, Hooks explains about her patriarchal family, her serious relationship and the liberation movement of women. Hooks asserts that patriarchal exists in various homes and classism/ racism exist in many movements of women. When Hooks combines these issues, she concludes that white women are generally victimized by the social system and the general population (Mahony & Zmroczek 46). Hooks has asserted that almost American neighborhoods have undergone class and racial segregation
