Colleges need to dissect the idea of email collaborations among instructors and students and progressively strong use of the internet as learning AIDSs is required among educators. Presentation Apparently instructors in conventional vis-à-vis college classs do non do rise to and viable use of the internet and web assets as guidance and larning AIDSs in the schoolroom. Contrasted with online classs. which are naturally web based securing destinations. the conventional college schoolroom has non profited by or exploited the web assets offered by new and immature the internet engineerings. This exploration analyzes the use of the internet and other interne devices at Winthrop University. The exploration is guided by the undermentioned research requests: Extra the undermentioned speculations arae tried: Writing Review Data and conveying building especially the figuring machine and the Internet. has affected numerous Fieldss and features of the general public including the field of guidance. The acknowledgment of building into guidance has brought about separation obtaining which is characterized as a ‘planned educating/learning experience that utilizes a wide range of engineerings to make researchers a ways off and is intended to advance student cooperation and confirmation of learning’ ( Greenberg. 1998. p. 36 on Akkoyunlu A ; Soylu. 2006 p. 44 ) . A mainstream kind of separation securing is on-line larning which is ‘the utilization of the internet to dish larning stuffs ; to interface with the substance. educator and different researchers. also, to get support during the learning methodology. so as to get cognizance ; to assemble individual essentialness ; and to abandon the larning experience’ ( Khan. 1997 on Akkoyunlu A ; Soylu. 2006 p. 44 ) . Online procurement has b ecome famous especially for working students. for the individuals who have family unit and kids and for the individuals who need to be taken a crack at unconventional school yet land separation confines them. Online obtaining has gotten all the more overall for occupied adults as it non only wipes out obstructions of separation and clasp however next to the despotic capacity of the instructor. The essential preferred position of online obtaining is that it offers an opportunity to larn without the limitations of clasp or area. providing flexibleness to larn at some random clasp and topographic point ( Cincinnati. 2007 ) . This implies online procurement plans are available every minute of every day for anybody took a crack at the arrangement consequently it is truly fitting even with occupied people ; understudies can break down at whatever point they have free clasp. This sort of procurement is extremely beneficial to vocation situated people who wish to encourage their guidance however do non hold sufficient clasp for conventional obtaining. Online procurement other than offers continuous scrutiny ; that is breaking down is non influenced when understudies needed to travel another topographic point or to modify an occupation. not at all like in conventional securing where students need to reassign to the closest school from spot or work. Besides. web based larning takes out inefficient clasp. stuffs and assets ( Cicognani. 2000 ) that is basic with conventional procurement. Web based larning disposes of movement cut from work or spot to class. Learning stuffs and assets are accessible online ; the internet is used to introduce quality talks that utilization picture. sound and sight and sound as securing apparatuses ( Harvard University. 2007 ) . Such learning AIDSs help do talks simpler to be comprehended. Online securing is ordinarily favored by more seasoned students and experts since it dispenses with the dictatorial capacity of and power per unit regions from the educators. Understudies can make their ain securing habits ; they become increasingly self-governing and answerable for their ain procurement ( Cincinnati. 2007 ) . Understudies do non hold to cover actually with their educators each piece great similarly as with the guidelines and approach of the physical school along these lines going progressively comfortable with breaking down. Understudies can other than pass on with their educators and even with individual students through electronic mail or gathering gave by on-line obtaining plans. Web obtaining permits adult researchers the flexibleness to locate their ain technique of larning without being forced on by an instructor. Hypotheses of adult guidance have ceaselessly underscored the use of fitting plans to run into the single requests of researchers. A portion of the trademarks of adult guidance. as featured by Lin. Cranton A ; Bridglall ( 2005 ) are independency. self-sufficiency and responsibility for securing. While the internet larning plans ordinarily encourage association among researchers and educator. the adult researchers in a general sense have full authority over their ain guidance. completing assignments and take separating in on-line medications on their ain undertaking. Web larning shifts the point of convergence from the instructor and spots the researcher at the focal point of larning encounters. As such adult researchers advantage well from the internet obtaining. In late mature ages a figure of colleges have been offering on the web and separation guidance possibilities. To ease students’ dish to college explicit data, for example, class stuff. instructors and different students. these colleges have made commonsense grounds. which are exceptionally dependent on the internet and web assets for usefulness. Chalkboard and WebCT are a couple of bundle organizations that structure. convey. what's more, keep up on-line classs. They have practical experience in capablenesss, for example, release sheets. confabs. electronic mail. what's more, listservs which are vital to online classs. In any case. like the online schoolroom. the internet can be an utile device in the customary schoolroom to uplift student procurement. Orchestrating to Pettijohn ( 2000 ) . the internet can loan essentially to bettering the schoolroom experience. The internet contains an abundance of data assets which are non confined by clasp or interminable ( Salend. Duhaney. Anderson A ; Gottschalk. 2004 ) and. in any case. it has been accounted for that college understudies depend rather, all things considered, on the internet. using it rather frequently. in this way instructors ought to happen methods of coordinating the internet into their classs ( Hiemstra A ; Poley. 2007 ) . Since the coming and quick expansion of the internet and the internet devices. explore laborers have been attempting to examine the similar effectivity of the conventional web missing or web restricted college schoolroom against a reasonable schoolroom which grasps the capablenesss offered by the internet. Numerous foundations. for example, Troy University and Winthrop University. hold gave the alternative of on the web/separation guidance choices to intrigued understudies. because of understudy planning alterations. the changing idea of the Fieldss in guidance. what's more, increment utilization of the internet building. These colleges have understood that. so as to exploit the new down to earth commercial center for college guidance. their classs and plans must reflect and fit in with the most up to date inclinations and the wants of the new purchaser base. This examination surveys how great conventional college classs are adjusted and keeping up with modifying designing. Appraisal of colleges and the nature of the plans that they offer should be an on-going system which will take to and illuminate modifications and advancements. Along these lines the discoveries of this overview will be somewhat applicable to college leaders. instructors. understudies and different partners in guidance in helping to flexibly a stage for bettering student comfort. open introduction. enrolling and answerability at colleges. Past research has mulled over comparable issues. breaking down instructors’ use of one or other web assets in determined classs. Duran. Kelly and Keaten ( 2005 ) gave an account of a review breaking down the use of electronic mail among educators and their understudies. The researchers’ end was to occur out the general frequence of understudy/educator email cooperations. the frequence of instructor started email connections. the reason for student starting connection with instructors. the reason for instructors beginning association with understudies and the perceptual encounters of educators regarding the use of this mechanism for pass oning with students. 259 instructors from two colleges finished polls which. on investigation. uncovered that understudies imparted rather regularly with educators through electronic mail yet instructors were less successive in

Purposes Types Examples Importance View All Back To Top The term  theory  is used with surprising frequency in everyday language. It is often used to mean a guess, hunch, or supposition. You may even hear people dismiss certain information because it is only a theory. It is important to note as you study psychology and other scientific topics that a theory in science is not the same as the colloquial use of the term. What Is a Theory? To the average layperson, the word theory means something of a guess. It might be true, or it might not be. But the word has a very different meaning in the realm of science when researchers are talking about empirical research that is back by scientific evidence. While the parlance of everyday language suggests that a theory is just a hunch, it is important to understand that the word has a very different meaning in science. In science, a theory is not merely a guess. A theory is based on a  hypothesis  that is backed by evidence. A theory is a fact-based framework for describing a phenomenon. A theory presents a concept or idea that is testable. Scientists can test the theory through empirical research and gather evidence that supports or refutes it. Scientific American listed theory as one of their seven most misused scientific terms.?? It is these misconceptions about the terms meaning that leads people to dismiss topics such as evolution and climate change as merely theories despite an abundance of overwhelming scientific evidence. A scientific theory presents an explanation about some aspects of human behavior or the natural world which is supported through repeated testing and experiments.  This means that scientists have repeated these experiments and replicated these findings. They have also collected evidence that supports the theory. Many different researchers have gathered evidence that supports the theory. Purpose of a Psychology Theory In psychology, theories are used to provide a model for understanding human thoughts, emotions, and behaviors. A psychological theory has two key components:It must describe a behaviorIt must make predictions about future behaviors Throughout  psychologys history, a number of theories have been proposed to explain and predict various aspects of human behavior. Some of these theories have stood the test of time and remain well-accepted today. Others have not held up under close scientific scrutiny and may have been rejected altogether or only partially accepted by researchers today. Each theory has helped contribute to our knowledge base of the human mind and behavior. Some theories such as  classical conditioning  are still well-accepted today.?? Others, like Freuds theories, have not held up so well and have been mostly replaced by new theories that better explain human development. The overall strength of a scientific theory hinges on its ability to explain diverse phenomena. What makes a theory so different from a mere guess or hunch is that a theory is testable. As new evidence and research are added, a theory may then be refined, modified, or even rejected if it does not fit with the latest scientific findings. Types Different of Psychological Theories There are many psychology theories, but most can be categorized as one of four key types: Developmental Theories Theories of development provide a framework for thinking about human growth, development, and learning. If you have ever wondered about what motivates human thought and behavior, understanding these theories can provide useful insight into individuals and society. Developmental theories provide a set of guiding principles and concepts that describe and explain human development. Some developmental theories focus on the formation of a particular quality, such as  Kohlbergs theory of moral development.?? Other developmental theories focus on growth that happens throughout the lifespan, such as  Eriksons theory of psychosocial development. Grand Theories Grand theories are those comprehensive ideas often proposed by major thinkers such as  Sigmund Freud,  Erik Erikson,?? and  Jean Piaget. Grand theories  of development include  psychoanalytic theory,  learning theory, and  cognitive theory. These theories seek to explain much of human behavior but are often considered outdated and incomplete in the face of modern research. Psychologists and researchers often use grand theories as a basis for exploration but consider smaller theories and recent research as well. Mini-Theories Mini-theories describe a small, very particular aspect of development. A mini-theory might explain relatively narrow behaviors, such as how self-esteem is formed?? or early childhood socialization. These theories are often rooted in the ideas established by grand theories, but they do not seek to describe and explain the whole of human behavior and growth. Emergent Theories Emergent theories are those that have been created relatively recently and are often formed by systematically combining various mini-theories. These theories often draw on research and ideas from different disciplines but are not yet as broad or far-reaching as grand theories. The  sociocultural theory  proposed by theorist  Lev Vygotsky  is a good example of an emergent theory of development.?? Examples Some of the best-known theories of psychology focus on specific branches within psychology. Some of these include: Behavioral Theories Behavioral psychology, also known as behaviorism, is a theory of learning based on the idea that all behaviors are acquired through conditioning. Advocated by famous psychologists such as John B. Watson and B.F. Skinner, behavioral theories dominated psychology during the early half of the twentieth century.?? Today, behavioral techniques are still widely used in therapeutic settings to help clients learn new skills and behaviors. Cognitive Theories Cognitive theories of psychology are focused on internal states, such as motivation, problem-solving, decision-making, thinking, and attention. Such theories strive to explain different mental processes including how the mind processes information. Humanistic Theories Humanistic psychology theories began to grow in popularity during the 1950s.?? While earlier theories often focused on abnormal behavior and psychological problems, humanist theories instead emphasized the basic goodness of human beings. Some of the major humanist theorists included Carl Rogers and Abraham Maslow. Personality Theories Personality psychology looks at the patterns of thoughts, feelings, and behavior that make a person unique. Some of the best-known theories in psychology are devoted to the subject of personality including the trait theory of personality, the big 5 theory of personality, and Eriksons theory of psychosocial development.?? Social Psychology Theories Social psychology is focused on helping us understand and explain social behavior. Social theories are generally centered on specific social phenomena, including group behavior,?? prosocial behavior, social influence, love and much more. Why Theories Matter In your  psychology courses, you may find yourself questioning how necessary it is to learn about different psychology theories, especially those that are considered inaccurate or outdated. However, all of these theories provide valuable information about the history of psychology, the progression of thought on a particular topic and a deeper understanding of current theories. By understanding how thinking has progressed, you can get a better idea not only of where psychology has been, but where it might be going in the future. Studying other scientific theories provides a background in what researchers understand about how the natural world works. A solid scientific education can help you make a better sense of what researchers mean when they talk about scientific research as well as improving your understanding of how scientific explanations for behavior and other phenomena in the natural world are formed, investigated, and accepted by the scientific community. While the debate continues to rage over hot topics such as climate change and evolution, it is worthwhile to study science and the theories that have emerged from such research, even when what is often revealed might come as a harsh or inconvenient truth. As Carl Sagan once explained, It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring. A Word From Verywell Much of what we know about human thought and behavior has emerged thanks to various psychology theories. For example, behavioral theories demonstrated how conditioning can be used to learn new information and behaviors. Some theories have fallen out of favor, while others remain widely accepted, but all have contributed tremendously to our understanding of human thought and behavior. By learning more about these theories, you can gain a deeper and richer understanding of psychologys past, present, and future.

The Better Angels Of Our Nature - 1209 Words

Today, in a social media ridden world where there’s no communication gap, allows news from around the world to be delivered to us in matter of seconds. Almost every day we hear about a shocking act of violence, whether it’s a terrorist bombing, a senseless rape or a gruesome murder. These tragedies makes us wonder, â€Å"What is the world coming to?† However, we forget to realize that in fact today’s world is much more peaceful compared to how dangerous life was thousands of years ago. As pinker stated, â€Å"Brutality was once woven into the fabric of daily existence† (2). Therefore, in order to understand the violence we witness today, it’s important to acknowledge how bad the world was in the past. In this paper, just as pinker did in his book â€Å"The Better Angels of our Nature†, I will also argue that violence has decreased tremendously over the centuries by using numerous evidence and statistical data. The Pacification process, Civilizing process, and other sanctions throughout millenniums are just some of the changes that resulted in the decline of violence throughout history. In his book â€Å"The Better Angels of our Nature†, Pinker uses works from Homeric Greece, evidence from The Old Testament, and early modern Europe to support his claim that after a millennia of bloody violence, human kind is entering a peaceful existence.

Social Media is Not the Mother of Narcissism Essay

Here’s a question, how often do you check your social media profile’s notification? Based on a research conducted, it is revealed that, Facebook users around the world logged into their account approximately 42,000 years of human time each day (Gutierrez, 2013). An article written by The New York Times stated that the current generations are becoming narcissistic and it is believed that social media are among the plausible factors that promotes it (Quenqua, 2013). However, how true can this statement be? Many researches have proven that social media is not the main cause of narcissism. It has been demonstrated via the real role of social media, the co-relation between social pressure and narcissism, the failure to conclude acceptance of†¦show more content†¦Despite their actions, they will not feel a sense of empathy towards the people they hurt because narcissistic individuals think the victims deserved it for stopping them from achieving their goals. Surprisi ngly, narcissistic individuals are always felt threatened by other people from their surroundings. Due to that, they are likely to respond to any perceived threats in an exaggerated way (Narcissism, 2008). Hence, narcissism is not exactly a trait you would probably found great in an individual. Throughout the years, numerous of researches are conducted to see the connections between social media (namely, Facebook) and narcissism. University of Michigan conducted a research to find the relationship between social media and narcissism. For the first part of the study, the researchers recruited approximately around 486 college undergraduate students with the median age of 19. Meanwhile, 93 adults, mostly white females, with an age mean of 35 years old, were asked by the researchers to complete an online survey for the second part of the study. Participants have to answer questions about their social media use and a personality assessment to measure their level of narcissism (Swanbrow, 2013).

Disconnected in an Interconnected World Free Essays

Disconnected in an Interconnected World Danielle Searle In a world filled with interactivity and interconnectedness, how is it possible to be so disconnected from the people who live the closest you? Peter Lovenheim’s article, â€Å"Won’t you be my Neighbor,† discusses this very ideal. After a terrible murder-suicide occurred in Lovenheim’s neighbor he was forced to asked him-self do I really know who lives next me? Lovenheim realized he didn’t and decided to something about it. He decided he was going to sleepover neighbor’s homes in order to get to know them better. We will write a custom essay sample on Disconnected in an Interconnected World or any similar topic only for you Order Now What Lovenheim should have taken into account is that, not everyone cares to â€Å"connect,† with his or her neighbors; others may simply just not have the time. And finally with the technology today, our â€Å"neighborhood† has grown to be more then the surrounding blocks near our home. Since when does living next door to someone automatically mean they have to be involved in your life? Lovenheim claims that, â€Å"Property lines isolate us from the people we are physically closets† to: our neighbors. (Lovenheim, 2008) When in reality it’s people that isolate themselves from other people. We all have freedom of choice. Just because you share an address, doesn’t mean you have anything in common with your neighbors. Starting a relationship with a person just because they live next door, is almost as idiotic as befriending someone just because they have a lot of money. Time is a huge factoring in life. People have to choose how much time to spend on different aspects of their lives based on priority, so sometimes time to make friends with neighbors is probably extremely low. Lovenheim asks, â€Å" Why is it that in an age of cheap long-distance rates, discount count airlines, and the Internet we often don’t know the people who live next door. † (Lovenheim, 2008) The answer to that question is that people are busy. For example a full time student, who also works, might not have a lot of time to get chummy with her neighbors. Or even a doctor who works the night shift at the hospital, or a new mom that’s focused on her newborn. Lastly, back in the day, your neighbors may have been important people in your life because they were all you knew. Most women stayed at home, so befriending neighbors wasn’t so shocking. Therefore it makes sense that in the 1950s neighborhood ties were way stronger. (Lovenheim, 2008) Today, with most men and women working there is even less likely of chance to get to know your neighbors.

The MEK lubricant and de

Introduction A lubricant’s de-waxing process involves removal of paraffinic hydrocarbons so as to improve the pour point of the feed stock. The pour point of oil is the lowest temperature in which oil can flow, pour or move when refrigerated or cooled without disruption under certain fixed conditions.Advertising We will write a custom research paper sample on The MEK lubricant and de-waxing method specifically for you for only $16.05 $11/page Learn More De-waxing produces high yields of products of improved quality base oils. Waxes require isomerization for their conversion into lubricant base oils. De-waxing processes create pure un-branched hydrocarbon chains without either aromatic contents or unwanted hetero-atoms in gas to liquid (GTL) processes (Gary Handwerk, 2001).During the de-waxing process, the solvent is subjected to a mixture of the waxy oil. In the catalytic de-waxing mechanism, wax components are reduced in the reaction to recapture the de-waxed oil molecules. A de-waxing process involves prior solvent extraction before the process is done. Heavy gas and oil from a refinery that is usually at very high temperatures is usually the feed stream. The gas is usually at high temperatures of 95 degrees Fahrenheit. This fact allows the feedstock not to crystallize. Shock treatment can cause formation of small crystals by the wax which would block the filter cloth during filtration process hence lowing wax recovery (Speight, 2010). The solvent is usually of equal temperature with the wax stream. It is then filtered through rotary filters. The primary rotary filter separates the stream into de-waxed oil or wax solvent stream. The de-waxed oil stream undergoes heat integration and continues to solvent recovery process. The wax or oil stream proceeds to the secondary filter. Here, it is separated into mostly solvent and wax with 3wt% oil content. The oily wax is de-oiled by re-melting to release trapped oil. The final fil tering step is the tertiary filter. It separates waxes into hard and soft ones. Soft wax is recycled and hard one is re-slurred and purified to food grade wax. De-waxing products can be categorized into two: 1. Base oil which is used to make lube oil for automotive and industrial lubricants and for production of automatic transmission fluids.2. Food grade wax which is used to produce sealants. Crayons, cosmetics, foods and candles are also produced from this wax. Lubricants’ oil de-waxing methods Lubricant manufacturers may use either catalytic or urea de-waxing or solvent waxing. During the catalytic de-waxing process, there is usually selective removal of lighter non- normal hydrocarbons and also an even removal of normal paraffin. Urea de-waxing is normally used to produce low pour points using urea.Advertising Looking for research paper on chemistry? Let's see if we can help you! Get your first paper with 15% OFF Learn More This process of de-waxing is good for recovering refrigeration and transformer oils because no refrigeration is required. It is important to include a desirable solvent because urea has no MEK properties. The viscosity of the oil has negative results in its contact between oil and urea. Difficulties are encountered during filtration, hence the addition of solvents. MSDW’s process This process uses a two-stage cascade system. It is shaped like a selective de-waxing catalyst in the second stage (Fleig, 2005). This system is highly flexible and functions with hydrogen pressures between 27 to 207 bars. The waxy oil and the hydrogen are mixed and then heated. They are then directed to the top of the de-waxing reactor. Downstream, the by-products which are basically low sulfur distillate, high-octane, naphtha and hydrogen-rich recycled gas are separated from the lube base oil (Pujado Jones, 2006). Propylene- acetone’s de-waxing process Propylene and acetone is the solvent mixture in this process. This proces s is adaptable to de-waxing plants that utilize propane instead of MEK (Fahim, Al-ShhafElkilani, 2009).Crystallization as a process is complex as it is usually determined by the rate of cooling of crystals. High and low cooling has an impact of the speed of the crystallization process and the quality of formed crystals. Propane is widely available as a byproduct in refineries and therefore its utilization is easier. This process leads to production of elements with low pour points, low refrigeration loads and reduced filter usages. Industrial technological research should focus on creation of catalysts that enhance the de-waxing of propylene and acetone instead of overreliance on products like propane. This fact would ensure that the performance of the solvent raw materials in this process is enhanced. MEK de-waxing method Methyl Ethyl Ketone (MEK) is an anti-oil solvent and thus dissolves little wax at low temperatures. It is a wax precipitating agent. Toluene is an oil solvent tha t dissolves the oil. At low temperatures, it maintains fluidity. A combination of major solvents is used in solvent de-waxing. MEK has become the most commonly used anti solvent in modern times but over reliance on it could lead to possible depletion of raw materials used in making it and consequent production of counterfeit products in the market. Industrial experts have advised that more research should be done to create new anti-oil solvents to complement the use of MEK. Nature of MEK de-waxing MEK has a poor solvent power and selectivity of paraffinic elements. It precipitates the wax leaving the de-waxed base oil. Studies have shown that the combination of toluene and MEK solvents in de-waxing processes causes an optimum wax precipitation of 40-75 v %. With increased MEK, the oil’s viscosity index increases but the solid point is maintained.Advertising We will write a custom research paper sample on The MEK lubricant and de-waxing method specifically for you for only $16.05 $11/page Learn More Process of MEK Flow diagram shows a de-waxing process The solvents used in this process are MEK and toluene which are mixed with the wax or oil stream feed. The feedstock is usually of high temperature; about 95Â °Farenheit therefore, the solvent added should have corresponding temperature. The solvent of the same temperature is again added. This fact prevents shock treatment. The mixture is then filtered through the rotary filters which separate the stream into de-waxed oil or wax solvent stream. Process variables MEK is highly preferred because of its distinct anti-oil solvent characteristic. All the other solvents have almost similar properties but MEK or toluene combination is the most commonly used one in refineries. High solvent as opposed to oil use improves the process of filtration. A high solvent facilitates faster crystal growth reducing the viscous nature of the varied streams. At 100 wt. % MEK, there is a significa nt wax recovery. High cooling rates have been reported to form undesirable wax that is hard to filter since it blocks the filters. Surface pressure exchanger The heat exchanger is used for crystallization of the wax. The process involves the use of the mid of the heat exchanger, the heated stream flows inside as the coolant flows on the outside. Wax crystals form slowly as the stream cools (Prestoris, 2004).Advertising Looking for research paper on chemistry? Let's see if we can help you! Get your first paper with 15% OFF Learn More The fact shows that there is usually poor heat conduction between the waxy feed and the coolant due to the formation of wax crystals. The surface heat exchanger contains scraper blades which are usually inconstant rotation (Gary et al, 2007). Their rotation removes clogged wax inside the pipe. This fact allows formation of more wax crystals. Figure 1 shows a surface heat exchanger Vacuum rotary filter Vacuum rotary filters are drums with a vacuum inside them covered by cloth. This fact prevents entry of the wax into the drum as the oil seeps in. This process removes any oil that might have been left in the wax. As the drum rotates, the scrapers remove the wax. It is deposited into a collection basin where it is re-slurred and re-melted with more solvent. It is used in separation of aromatic impurities and naphthalene by precipitation or dissolving of the components. Filters’ process operation In its operation; liquid is sent to tube units set below a drum. The drum cycles th rough the liquid and the vacuum pulls the solids away from the liquid into the drum pre-coat system. The liquid sucked through the filter causes the solid to stick to the outer surface of the drum. Figure 2 shows a vacuum rotary filter Maintenance and protection of the system Maintenance and protection of the system has to involve the maintenance of the various filters. The oil or the coolant filters has to be changed after every 500 hours so that they can clean away the contaminants. The oil separator has to be changed with change in oil for it to separate oil from air effectively. The drive belt has to be changed after 800 hours for effective performance. Other equipments used in this process include chillers with heat exchangers which gradually lower the temperature of the mixed stream of solvent and wax or oil to allow crystallization to take place. The others are the de-waxed oil and slack wax evaporators. Features of the vacuum rotary filters Their features include drum, val ve, drum deck, filter cloth, internal piping, agitator and the tank. These features are small in size and structure to facilitate faster operation. They are powerful and suffer low labor intensity making them easy to operate. The drum is supported by the trunnion which is set at the end of valve. It helps in formation of the vacuum cell at the bearing end. The valves are used to regulate the cycle sequence. Each portion is exposed to the vacuum, the dead zone and the blow. The valve contains adjustments blocks and fixed forms which creates the drying ratio in the filtration process. The internal piping can be single or double row piping to facilitate the channeling of the filtrates, steam and waste. The drum deck is separated into compartments waved to the vacuum or the rotating drum. The filter cloth acts as the cake tied to the drum face and it’s made from propylene or polyester. The agitator suspends the sludge material as the tank houses the drum and the agitator. Vacuum and rotary filters’ process variables The process variables in rotary filtration involve temperature, pressure, solid content and particle size and distribution (Parkas, 2003). The variables define the present status of the process. The temperature is usually maintained high with operational temperatures going as high as 2000C. High temperatures are required for distillation, evaporation and thermal breakdown. Pressure is crucial and is maintained at 6 bars with the pressure filters taking different timing like 10 minutes for cake application and 8 hours for polishing. The solid contents take about 50% or more of the weight with the particle distribution being 1 to 2 microtones. Chillers These equipments are heat exchangers which gradually lower the temperature of the mixed stream of solvent and wax or oil to allow crystallization to take place (Lum, 2011). They are specially designed to scrap out the wax deposits in the heat exchanger surface so as to have efficient heat tr ansfer. Chilling involves direct heat transfer. Evaporators The evaporator is used in recovery of the solvent from the de-waxed oil and wax. Components include the motor which rotates the evaporating flask, vapor duct that channels the sample, vacuum system that reduces pressure, water bath for heating the sample and the condenser that acts as a coolant. Solvent recovery system The solvent recovery system supplies parts and services for recycling equipment, wastewater treatment and washing of parts. The process reduces the cost of disposing solvents and waste water charges. The solvent recovery system involves the following process as shown in the diagram. Solvent used The solvent de-waxing stem involves MEK, toluene, propane benzene ,methylene chloride, ethylene dichloride, sulfur dioxide and cyclohexane.MEK is used in industries in the dissolution of wax at low temperatures.

A new development in lubricants’ de-waxing processes The industry is facing a lot of development with respect to technological advancement. Nowadays, there is greater use of the skill in solvent extraction. Industries are producing edible vegetable oil from oil seeds and protein units that are nutritious and economically viable. Capital investment is prioritized. The industry is making efforts in investment and money making through incorporation of various ideas in respect to this industry. The food industry also applies the PEG-NaCl system to fragment small molecules like nucleic acids and peptides. Informati on on DNA purification is important in generating biotechnological purified genetically material. Conclusion The MEK lubricant and de-waxing method have proven to be useful industrial components (Favennec, 2001). More research should be done to improve their performance in industrial processes. The government should allocate more funds to safeguard industrialists from fraudulent people who sell counterfeit products hence reducing the marketability of the MEK lubricant. The de-waxing method has also proved to be a resourceful one and scholars should devise easier ways of understanding the solvent extraction system, heat exchanger and the functioning of the filters because it is important considering that health and ethical standards have to be adhered to.

Organism essays

Organism essays Every organism at one time or another has to learn to adapt to a new environment. This is why evolution of organism is needed in order to survive changes to its environment, such as the case of the flightless birds. For one reason or another over a period of 100,000 years the need for wings was unnecessary to their survival. There could be many reasons why the birds evolved to be more adaptable to their environment. A small population of birds would have to replenish and start a new population. In all populations there are great reproductive potential to replace numbers and expand the number of population. After their population grew there would be a leveling off of the population once it reached a stable size. The birds' population would become stable due a lack of food to support every bird in the population, along with predators helped to contribute to keeping the population stable. After being on the island a while the birds' population would start showing a variation in differen t traits. Such things as color, wing size and overall size may vary, due to predators and the terrain of the environment. Eventually the birds evolved to the point where the use of their wings was no longer needed, as a necessity to survive. The adaptation could have been because flying itself took to much energy, so to conserve food they didn't fly too much. The bird's food also could have been close to the ground and there was no need to really fly. Another thing could have been that it was hard for predators to catch the birds if they stayed in think under brush or traveled along the ground. For whatever reason the birds didn't need their wings this trait was passed of from generation to generation. The reason this trait was passed on was because it helped the survival of these individual birds. They were able to reproduce and pass these traits through heredity. ...

Monopolies and Oligopolies Essay Example | Topics and Well Written Essays - 500 words

Monopolies and Oligopolies - Essay Example However, this competitor does not fit the definition of close substitute and has difficulty entering the market. Apple has recently introduced the Windows Operating System on its machines and has reinforced Windows as a monopoly. Consumers are tied to Windows for practical reasons as well as the piece of mind that familiarity brings and they can find no close substitute. When consumers can find no close substitute and are locked into a data processing system, it allows Microsoft to charge whatever the market will bear. In the Microsoft model, they have priced their software at the level that will produce the greatest returns without effecting demand. This has allowed them to optimize their pricing based not on demand, but as price setters. This is another indication that they are a monopoly. People will no sooner switch from Windows than they would buy a rhinestone engagement ring as a substitute for a DeBeers diamond, no matter what the cost. The fact that they have a barrier to entry, can set the price on their own terms, and have a consumer base that will not accept a substitute makes Microsoft one of the largest monopolies in the history of the world Similar

Mario Escobar, Matias Ramos, and Stephanie Solis - Assignment Example The paper tells that Matias Ramos, who was not eligible, for in-state tuition and his parents. They were not able to rise for his fees struggled hard until he was able to complete his four-year course in college. Stephanie Solis too had financial difficulties when she enrolled to UCLA. She decided to become a housecleaner; she made cardboard boxes and tutoring which helped her save money that enabled her to get through UCLA. The Langston Hughes poem, â€Å"A Dream Deferred† reflects a dream, which achievement is by hard work. The poem relates to the stories of Matias Ramos, Mario Escobar, and Stephanie Solis since their dreams were achieved through a tough struggle and hardships. In the poem, the dream is a load that is so heavy to bear and can not let one go a milestone to achieving the desired goals in life. The dream in the poem is full of pain, sorrow, and hardships that are not worthy to bear and can only be achieved by one who can only live the hard way out. As in the ca se of Mario Escobar who after surviving the El Salvador's brutal civil war where he lost his parents, he never gave up but struggled the hardest way out to achieve his dreams. The same applies to Stephanie Solis and Matias Ramos whose dreams were like a heavy load that had no signs of exploding, but through struggle, they are at the top of their dreams.

Media’s Role In Body Images Essay -- Media Advertisements Advertising

Media’s Role In Body Images Authors can effectively get their point across by using different rhetorical techniques. In the two articles that I will examine, the authors mainly used a pathos appeal. Authors use pathos to get a social and emotional application across to the reader. Another rhetorical technique that is used by many authors is ethos. Ethos is a technique that can be used by an author saying that since they are perhaps a doctor or may have belonged to a certain organization for a long time, then they know more about a topic than somebody who may not have had the same moral values or interests. Logos, or the logic that the reader may conclude from the author, is an additional rhetorical technique that is commonly used by authors. These three appeals are the best way for an author to get his point of view across to the reader. Authors that are writing about the same topic might not use the same appeals, nor may they use identical appeals in the same way. Consequently, Colleen Thompso n author of Society and Eating Disorders and David Butler author of Slim Pickings are both getting the idea that society and the media play a role in the behavior of how people feel about their bodies, but they use different appeals to get their points across. The two articles, written by Thompson and Butler, deal with the issue of how people, especially females, deal with the media’s role concerning weight issues. As the year 2000 rolled in, actresses’ and models’ body weight decreased, and their waiflike bodies became more noticeable in the public’s eyes. Many little girls grow up idealizing the people in the public eye, giving them the idea that they must look a certain way, which is not a healthy way.... ...ns where you can find out about weight loss & fitness. Thompson has links that can help out people. She has a bunch of icons to click on; for example, if you want to know signs of problems you can click on signs, or if you want to get help you can click on either getting help or therapists. Even though Thompson’s article is less appealing to the eye, she has more icons that can help someone better understand problems that are associated with media and weight loss. Butler and Thompson’s article’s are very informative, and help people to better understand the problem’s people are faced with today. Even though both authors use different techniques to get the reader to better understand how they feel about their topic, the reader can learn from both papers. I feel that these two authors used very good techniques, and they are both respectable papers.

Lab Report: Blood Pressure Essay

The woozy feeling when standing up too quickly. After going for a run, feeling as if one more beat and the heart would project itself out of the chest. Or quite the opposite and being in a very relaxed state. These are all changes one experiences at some time or another. What causes the different feelings and how each variable affects pulse rate and blood pressure has many wondering. Because of this curiosity, an experiment was performed to get some answers. The purpose of the experiment is to see how different variables affect pulse rate and blood pressure. Before starting the experiment, self educating on background information was a necessity in order to obtain a full understanding of what exactly was going to be performed. What is blood pressure and how does it work? â€Å"As the heart beats, the heart pushes blood through a network of blood vessels called arteries. As the blood travels through the arteries, it pushes against the sides of these blood vessels and the strength of this pushing is called blood pressure.† (Blood Pressure UK) After getting the basic definition of what blood pressure is, it was learned that when blood pressure is taken the first number that is said is the systolic blood pressure level or the highest level that is reached when the heart is squeezing. The second number that is read is the diastolic pressure level or the lowest level when the heart is relaxing, which is measured in mm Hg. (Blood Pressure UK) Moving on to pulse rate, also known as heart rate. It is known that pulse rate is the number of times the heart beats in one minute. (Gordon) Pulse is lower at rest and increases when higher activity is performed, like exercise. (Gordon) Pulse is taken by putting the tips of the index finger and middle finger onto the palm side of the opposite wrist below the base of the thumb. (Gordon) By pressing lightly with fingers, one could feel the blood pulsing beneath the fingers. (Gordon) After counting for ten seconds, the number of beats felt is multiplied by six to get the heart rate per minute. (Gordon) Normal pulse is between sixty and a hundred beats per minute. (Gordon) Posture Changes, Exercise, and Cognitive Stressor are the three variables to be tested. First, the focus will be on posture changes. More specifically, reclining for three minutes. It is hypothesized that both, arterial pressure and pulse rate, will decrease because the heart doesn’t have to work as hard to distribute blood to the body. Normally it takes more effort to deliver blood to the body is erect. After reclining for three minutes and standing up quickly, it is hypothesized that pulse rate will decrease because the act of standing takes a good amount of blood that travels down into the legs causing less stroke volume for the ventricle to pump. Once standing for three minutes, it is hypothesized that the arterial pressure and pulse rate with both increase. As it is increasing, it will also be recognized that the arterial pressure and pulse rate will return to baseline. Once data is collected from the variable of posture changes, exercise will be the next variable to look at. Immediately after exercising, it is hypothesized that arterial pressure and blood pressure will increase. It is thought because the body is performing high activity, it means that the heart has to work faster to be able to successfully perform venous return which then increases stroke volume and as a result increases cardiac output. Not only will the arterial pressure and pulse rate increase, it will be at its max range. Two minutes after exercise, it is hypothesized that the arterial pressure and pulse rate will decrease. Because the body is starting to calm down and come back down to resting, the heart doesn’t need to produce as high of stroke volume therefore decreasing the cardiac output. Focusing on the last variable of cognitive stressor, the subject will have to spell a list of words forwards and backwards. It is hypothesized that while doing this, the subject arterial pressure and pulse rate will increase. This is to be thought because while the subject is spelling the words the mind will be under a lot of stress therefore causing acts of anxiety or nervousness to arise, making the heart beat faster than normal. Procedure: â€Å"For procedures, refer to Lab 6, Activity 2, in the Anatomy and Physiology Lab Manual.† Discussion/Conclusion: To start off the experiment, a baseline was needed in order to be able to compare the different variables through out the experiment. The subject was instructed to sit and relax quietly while the blood pressure cuff and pulse plethysmograph were placed properly. After the blood pressure was taken and analyzed, it was found that the subject’s blood pressure was 122/64 mm Hg and a pulse rate of 60 bpm. Now that the baseline was obtained, continuing with the changing variables could take place. Starting with the variable of postural changes, the subject first reclined for three minutes. After the two minutes, the subjects blood pressure and pulse rate was taken and gave a reading of 120/52 mm Hg and 60 bpm. Looking back at the hypothesis, it was hypothesized that after reclining for three minutes the arterial pressure and pulse rate will both decrease. Cross referencing the given data with the hypothesis, it was found that the results didn’t fully match with the hypothesis. The blood pressure did, in fact, decrease due to the relaxation state that the subject was in. On the other hand, the pulse rate stayed the same. Reflecting on that and looking at the variables in the environment, it could be said that the subject wasn’t in a state of full relaxation. The subject was instructed to recline on a cold lab table with other subjects and groups in the room. It is possible that the discrepancy in this experiment was the environment in which the subject was instructed to recline and relax. After reclining, the subject was instructed to stand up quickly. Right when the subject stood up, blood pressure and pulse rate were recorded. It was collected that the subject’s blood pressure was 132/58 mm Hg and pulse rate of 62 bpm. Relating back to the hypothesis, it was said that the arterial pressure and the pulse rate would decrease. The results obtained and the hypothesis did not match. Further dissecting why the data didn’t match the hypothesis, it was discovered that because the subject stood up very quickly, 500 mL or more travels down into the legs. It was thought, due to that reason it would mean less stroke volume for the ventricle to pump. Looking at it from a different angle, because the amount of blood that travels to the legs, it actually causes the heart to work more rapidly to evenly transport regular amounts of blood through out the body causing the arterial pressure and the pulse rate to increase. Once the subject was standing for three minutes, the reading of the blood pressure was 130/52 mmHg and the pulse rate was 64 bpm. Comparing to the hypothesis, it was said that the arterial pressure and pulse rate would increase trying to bring the body back to baseline. Looking at the results, the blood pressure, in fact, decreased and the pulse rate increased, making the results partially confirm the hypothesis. Because it didn’t completely confirm the hypothesis, it could be said that the subjects body wasn’t able to get the body completely back to baseline in three minutes. It may have taken a few more minutes in order for the body to get back to a regular state. After those variables were explored, the next variable tested was exercise. Instead of there being only one subject, two subjects were used. Subject #1 was a well conditioned subject, someone who works out on a regular basis and already has endurance. Subject #2 was someone who was poorly conditioned, who never does strenuous activity. Before any physical activity, a baseline was required so there was data that can be compared. The well conditioned subject’s baseline was an arterial pressure of 118/70 mmHg and pulse rate of 61 bpm. The poorly condition subject’s baseline read as arterial pressure 122/44 mmHg and pulse rate of 60 bpm. Both subjects were instructed to exercise for five minutes, which consisted of running up and down the stairs. Immediately after exercising, the reading of the arterial pressure and pulse rate were taken. The well conditioned subject’s arterial pressure read 162/62 mmHg and pulse rate of 76 bpm. The poor conditioned subject’s arterial pressure read 139/60 mmHg and pulse rate 80 bpm. The hypothesis was confirmed that immediately after exercising, the arterial pressure and pulse rate would increase. Not only would it increase, but it would be at a max range. The venous return increased due to the increase in skeletal muscle activity. Increasing venous return, increases stroke volume, which then increases cardiac output. One minute after exercising, the subjects arterial pressure and pulse rate were recorded. Subject #1’s arterial pressure was 138/70 mmHg and pulse rate was 74 bpm. Subject #2’s arterial pressure was 134/65 mmHg and 76 bpm. The hypothesis was confirmed that the arterial pressure and pulse rate would decrease but still higher than baseline. As you see reflected in the â€Å"Results† section above, two and three minutes after exercising the blood pressure and pulse rate decreased, further confirming the hypothesis. The third and final variable tested was cognitive stressor. The subject was instructed to read 12 spelling words forwards and backwards at five second intervals. Before, just like any experiment a baseline needed to be obtained. After the reading was recorded, the first test began. The subject had to spell a series of words, as this was happening, the subject was hooked up to iWorx which is a system that reads blood pressure and pulse rate. Once the test had ended, the data was analyzed and it was found that the hypothesis of the pulse pressure and blood pressure increasing did not apply to the first part of the test. The subject’s blood pressure had decreased while the pulse pressure increased. The discrepancy was thought to be that the subject was very comfortable in spelling words therefore the blood pressure decreased but the pressure from spelling in front of other people may have caused the pulse rate to increase. The subject then spelled a series of words backwards, this further confirmed the hypothesis that the blood pressure and pulse pressure would increase. The focus on spelling the words backwards correctly and the pressure of people watching the subject caused the increase in blood pressure and pulse pressure. Throughout this experiment, it was interesting to see how to different variables in every day life can effect ones blood pressure and pulse rate. For the most part, each hypothesis was confirmed. The hypotheses that weren’t confirmed, it was an obvious discrepancy that explained why the experiment didn’t work out as planned. What can be taken from this experiment is that one can maintain a certain level of arterial pressure and pulse rate by the activity that is performed. Arterial pressure and pulse rate are very sensitive and can change at any moment. It is good to be knowledgable on what factors effect blood pressure and pulse rate; also on how it effects your body.

Racial Disparities in the American Criminal Justice System: Rates of Incarceration of Blacks vs. Whites No Equal Justice in the American Criminal Justice System Shawn Y. Williams Troy University-Fort Benning CJ 5571 Probation, Pardon, Parole Instructor’s: Dr. Ronald Craig April 28, 2007 Abstract Racial inequality is growing. Our criminal laws, while facially neutral, are enforced in a manner that is massively and pervasively biased. My research will examine the U.S. criminal justice policies and how it has the most adverse effect on minorities. According to the Justice Department’s Bureau of Justice Statistics, out of a total population of 1,976,019 incarcerated in adult facilities, 1,239,946 or 63 percent are†¦show more content†¦Less is known about the extent of discrimination at the arrest stage, in part because underlying rates of criminal activity by race cannot be easily assessed. Some evidence comes from comparing the race distribution of offenders derived from victims’ surveys with the racial composition of individuals arrested for the same crime. Two studies have found that these distributions are roughly comparable for many violent crimes. African Americans constitute 12% of the U.S. population, 13% of the drug using population and fully 74% of the people sent to prison for drug possession. Studies have shown that minorities are subject to disparate treatment at arrest, bail, charging, plea bargaining, trial, sentencing, and every other stage of the criminal process. These disparities accumulate so that African Americans are represented in prison at seven times their rate in the general population; rates of crime in African American communities is often high, but not high enough to justify the disparity. The resentment destabilizes communities and demeans the entire nation. (Justice, 2004) Human Rights Watch research shows that in every state, the proportion of blacks in prison exceeds, sometimes by a considerable amount, their proportion in the general population. In Minnesota and Iowa, blacks constitute a share of the prison population that is twelve times greater than their share of the state population.
