The Poisonwood Bible By Barbara Kingsolver - 1124 Words
In the novel The Poisonwood Bible, written by Barbara Kingsolver, the reader is introduced to the Price family, Baptist missionaries who are attempting to ââ¬Å"Christianizeâ⬠the country of Congo, more specifically the village of Kilanga. As the story progresses, the family realizes that they are not changing the Congo; instead, the Congo is changing them. The development of the characters within the novel is due to the instrument of cruelty. Although distasteful to regard it as such, cruelty motivates the development and choices of its subjects, whether politically, culturally, or socially. Rendering itself as a main theme throughout the book, different aspects of cruelty are illustrated through the interactions of the Price family, internally and externally, as well as the overall relationship between the ââ¬Å"white menâ⬠and Congo, or more generally the continent of Africa. If one extends their outlook unto Africa, the novel demonstrates the disgraceful actions that the continent endures. Deemed as the ââ¬Å"white menâ⬠by the villagers, the countries of Belgium and the United States are the main abusers to this land. By utilizing their military power, both countries take advantage of the weakened state of Africa and manipulate the present government to favor their liking. As their efforts are met with immediate backlash from the public, the countries attempt to validate their selections. They have their ââ¬Å"puppetâ⬠Mobutu, the selected president, urge the ââ¬Å"US advisors to hold electionsâ⬠¦Show MoreRelatedThe Poisonwood Bible By Barbara Kingsolver1352 Words à |à 6 Pagessuccessful.

The Dark Side of Social Media - Free Essay Example
Sample details Pages: 3 Words: 881 Downloads: 10 Date added: 2019/04/10 Category Society Essay Level High school Tags: Social Media Essay Did you like this example? If one observes the people around them in most any public setting, chances are, many have their eyes gazing in a sort of hypnotic trance, being absorbed into the glow of their phone screens. Our modern society has become disturbingly dependent on the various forms of technology, one of which, being social media. Social media has completely transformed the way we connect with others, almost to where we no longer need to communicate with anyone in person. Donââ¬â¢t waste time! Our writers will create an original "The Dark Side of Social Media" essay for you Create order Why take the time out of our busy schedules to have a face-to-face conversation when one could accomplish nearly the same thing through a smartphone? That is the alarming mindset that many people have adapted to, especially the younger generation, and it is the very thing that makes social media so dangerous. Although it can be a great way to stay in touch with old friends, or keep up with important information, there are several negative factors of social media that interfere with having authentic social experiences, and more people should be aware of these potential harms. The addictive properties of social media are one of these negative factors. When most people think of addiction, images of drugs or alcohol come to mind, along with their dangerous physical and mental effects. Some may not consider social media to be a real addiction because it does not present itself in the same manner as other common substances. However, repeatedly engaging in anything despite its negative cons equences could still be considered a form of addiction. Though it may not be especially life threatening, the compulsive use of social media is still worth some concern. According to an article discussing this topic, the chemicals in our brain are to blame for some of social medias addictive properties. When one receives a notification on their phone, the brain is flooded with the chemical dopamine, causing feelings of happiness. the brain enjoys this rush of dopamine and causes one to check their phone again and again in order to re-create that rewarding feeling. The article states that 72% of teens sleep with their phones nearby, 60% text while doing homework, and 72% feel pressure to respond to notifications immediately. These statistics show the strong association one makes between social media and pleasure, and how difficult it can be resist checking those notifications. Even if it is something as insignificant as a like on Instagram or a comment on Facebook (Carro). Another factor equally as concerning, is that social media may cause a decrease in social skills. As a result of its addictive properties, it seems as though more people are becomin g overly comfortable with communicating through social media instead of talking in person. Out of one thousand teenagers ages thirteen to seventeen, 61% prefer talking online instead of in person (Loveland). Although some may say social media is overall more convenient, could interacting too much through technology damage a teens social development? With this idea in mind, researchers from UCLA conducted a recent study to test pre-teens ability to interpret non-verbal cues, which is a crucial factor of good communication and social skill. For 5 days, half of the children were sent to a nature camp that lacked access to any screen-based media. They were then compared to the other half of the participants who continued with their normal use of media, which averaged over four hours per day. Both groups took a pre- and post-test that required them to read emotions from photos and videos containing no audio. The results showed significant improvements with reading non-verbal cues in the group that was removed from social media. The control group, however, showed little to no improvements. This study is an excellent example of how social media may be more of a barrier in socialization rather than a positive source of interaction. As a result of all these negative factors discussed, social media may also have the potential to be harmful to ones mental health. The addictive properties, combined with the lack of social connection, could spiral in to a loop of isolation. This can be risky for anyones mental state, especially that of an unsecure teenager. Psychologist Ethan Kross and others conducted a study on the mental well-being of Facebook users. The results confirmed there is indeed a link between mental health problems, and social media. The researchers write, Facebook provides an invaluable resource for fulfilling the basic human need for social connection. Rather than enhancing well-being, however, these findings suggest that Facebook may undermine it (Kross et al.). Overall, there are few inventions tha t have affected our lives as profoundly as social media. It is assumed that teens will continue to successfully adapt to their environment as they always have in the past. However, I think its possible that the very quality that makes teens so adaptable also makes them vulnerable. Social media undoubtedly has an abundance of positive uses that have been a great advance in technology. But without being cautious, it can manipulate one into spending more of their time aimlessly scrolling online instead of interacting with others. This is what causes the confusion between a real, meaningful connection and an artificial, digital one. It is important that everyone, especially teens, should be more aware of the gimmicks of social media, and the potentially harmful affects it has on their wellbeing.

The Consequences Of Global Warming - 1579 Words
The Consequences of Global Warming What does someone think of when the topic of global warming is presented? They might think of the earth warming, or the sun burning up, but do they think of the affects this issue has caused our Mother Earth or think about what they do on a day-to-day basis as being the prime contributor to this environmental problem? Do they realize or even worry about the next generation dying because of the various factors of global warming? Some may think of global warming as a tale or publicly over-rated, but what they do not realize is that global warming has become one of the top three environmental problems of the century.

Forced Air Induction Essay Example For Students
Forced Air Induction Essay The Garret Aviation VNT-25 The idea of forced air induction by turbine, orturbo, is not new and has its mass production roots in WWII fighter planes. What is new, however, is its application to passenger automobiles. Unlike a nearconstant high RPM fighter engine, an automobile requires wide-open throttle (WOT)power availability throughout its entire operating range. Previous automotiveturbo applications acted like an on-off power switch with a five second delay,decreasing drivability, rather than providing the smooth linear powerband of anormally aspirated engine. Because the turbine is in a fixed position in theexhaust stream, it was plagued with sometimes uncontrolled production from thecompressor at high engine speeds, commonly referred to as boost creep, and asignificant decrease fuel economy versus a similar, but naturally aspiratedengine. The Garret Aviation produced VNT-25 solved all of these problems withits innovative Variable Nozzle Turbine. Hands down it is the most advanced turboever mass-produced and it was the first of its kind on production cars. One ofthe most talked about problems with turbo charged engines is the lengthy time ittakes for the turbo itself to accelerate to operational speeds. This is commonlyreferred to as turbo lag or turbo spool up time. Under WOT, turbo lag results ina seemingly underpowered engine that suddenly comes to life as a delayed tiremelting rush of acceleration. Previously, turbo lag was limited by decreasingthe size of the turbo itself. This resulted in lower rotating mass and moreimportantly, a smaller cross sectional area, which accelerated exhaust gasses atlower engine speeds. Although the turbo is able to spool quicker due to itssize, for the same reason its ability to move and compress large amounts of airefficiently is significantly reduced. Inherently a smaller turbo will produceless maximum horsepower than if it were replaced by larger turbo on the sameengine. Previous turbochargers also used a fixed position turbine that poweredthe centrifugal compressor directly. Because the turbine is located directly inthe exhaust stream, the turbine is a huge exhaus t restriction. This restrictioncreates a constant exhaust backpressure that decreases fuel economy even whenthe turbo is not in use. At high engine speeds, the restriction creates enoughpressure in front of the turbine (back pressure) that the wastegate can nolonger limit turbine power by bypassing the exhaust around the turbine. Theresult is that turbo compresses more air into the engine than is wanted. Forexample, a turbo was set to produce a maximum 12psi boost pressure, but during aperiod of sustained wide open throttle high engine speeds the turbo is nowproducing 14.5psi of boost and still rising. This unwanted phenomenon is calledboost creep. The VNT-25 solves all of these problems with an innovative turbinecalled a Variable Nozzle Turbine. Rather than a fixed turbine the VNT-25 uses aring of 12 moveable paddles aligned around a central, but very small turbinewheel. The entire exhaust charge is then directed to the small turbine by thepaddles. Moving the paddles varied the cro ssectional area that the exhaust mustpass through. When the paddles are nearly closed the exhaust is acceleratedtowards the turbine wheel to increase power. Decreasing the crossectional areaof flow accelerates normally slow, low engine speed, gasses and nearlyeliminates turbo lag while allowing a large and efficient compressor wheel forexcellent maximum engine power. Opening the paddles allowed the exhaust to flowslower and bypass the turbine to limit power. This unique arrangementsignificantly reduced backpressure, greatly improved fuel economy, and allowsexcellent control turbine power at sustained high engine speed, without the useof a bulky external wastegate. The Garret VNT isnt without its drawbacks. Inhigh performance applications it is a turbo that has little to be desired. Theengineers of this turbo, in their effort to reduce turbo lag as much aspossible, kept the compressor and turbine as small as possible. The smaller sizeof the turbine and the compressor decreases the si ze and therefore the weight ofthe turbo internals. Keeping the weight as light as possible reduces rotationalinertia to an absolute minimum, which results in a much more responsive turbo. .u94ad880034e0b7c3fd70f54b37de133d , .u94ad880034e0b7c3fd70f54b37de133d .postImageUrl , .u94ad880034e0b7c3fd70f54b37de133d .centered-text-area { min-height: 80px; position: relative; } .u94ad880034e0b7c3fd70f54b37de133d , .u94ad880034e0b7c3fd70f54b37de133d:hover , .u94ad880034e0b7c3fd70f54b37de133d:visited , .u94ad880034e0b7c3fd70f54b37de133d:active { border:0!important; } .u94ad880034e0b7c3fd70f54b37de133d .clearfix:after { content: ""; display: table; clear: both; } .u94ad880034e0b7c3fd70f54b37de133d { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u94ad880034e0b7c3fd70f54b37de133d:active , .u94ad880034e0b7c3fd70f54b37de133d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u94ad880034e0b7c3fd70f54b37de133d .centered-text-area { width: 100%; position: relative ; } .u94ad880034e0b7c3fd70f54b37de133d .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u94ad880034e0b7c3fd70f54b37de133d .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u94ad880034e0b7c3fd70f54b37de133d .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u94ad880034e0b7c3fd70f54b37de133d:hover .ctaButton { background-color: #34495E!important; } .u94ad880034e0b7c3fd70f54b37de133d .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u94ad880034e0b7c3fd70f54b37de133d .u94ad880034e0b7c3fd70f54b37de133d-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u94ad880034e0b7c3fd70f54b37de133d:after { content: ""; display: block; clear: both; } READ: A Room Of One's Own Essay Because the exducer, that is the compressor, is of a compressor type,operational speeds are very high. It is not unlikely for a VNT to reach maximumoperational speeds of 173 thousand revolutions per minute even though resting orcruise speed of the turbine is only 2000-6000 RPMs. It is thislatency of the turbo to accelerate to operating speeds that is referred to asturbo lag. Although the small size of the turbine is ideal for a moderateperformance car, its size is a handicap in racing situations. Inherent with asmall compressor is its ability to quickly reach operating boost pressure. Thisdoes not come with out a penalty. Effectively this small compressor tradesefficiency for speed. As any gas is compressed the temperature of it rises. Smaller compressors will tend to heat the compressed air more than would alarger turbo for a given pressure. Bernoullis principal states that as a gas iscompressed the temperature increases as the volume decreases. The inefficiencyof the VNT at pressures over 15 pounds per square inch increases the temperatureof the gas more than it is possible for it to compress, or decrease the volume. The result is that the increase in boost pressure is inversely proportional tothe volume of air moved. As the compressor works to decrease the volume of air,the rise in temperature works to increase the volume. Eventually the volume ofair is expanded by heat more than it can be compressed. The point at which thishappens is referred to as the stall speed. Because a larger turbo, although slowto respond, is much more efficient at higher pressures it will result in a muchcooler charge at a given pressure. A smaller compressor also cannot move largequantities of air at high pressures as would a larger turbo be able to. The sizeof the VNT, although ideal for 12psi as it was intended for, suffers greatly inhigh performance applications from stall speed of psi. The turbine also suffersfrom a small and compact A/R ratio. The A/R is the ratio at which the turbine orcompressor housing is cast. The A/R is the ratio at which the volume of thehousing as gasses enter the housing to the volume it e xits. For instance, thesize of connection on the intake side of the compressor is two and one quarterinches inside diameter and has a volume of 323 cubic centimeters until itreaches the compressor. The exit side is also two and one quarter inches insidediameter and contains a volume of 155ccs. The volume of each path to thecompressor is misleading and cannot be determined from the diameter of the exitor intrance alone. The intake passage is a direct and simple path to thecompressor cartridge. The exit, however, is fluted from the from a very wide andnarrow, almost rectangular, passage at the side of the compressor to a standard2 inch inside diameter round pipe fitting. This fluted shape insures that thespeed of the compressed charge is kept relatively high. The high speed maintainsthat the compressed charge is kept away from the compressor. If it were allowedto back up near the compressor, the compressor would have to work much harder tomove the already dense air. The result would b e that the clready compressed airwould be further compressed and heated. Although the small inlet and outletsizes contribute to increased velocity With the introduction of the GarretVNT-25 it is now possible for a small displacement turbo charged engine tooperate and perform nearly identical to a much larger engine. The ON/OFF switchof turbo power is gone and is now replaced by the safer, smoother, and much morelinear acceleration comparable to naturally aspirated engines of much largerdisplacement. A VNT-25 equipped engine also has the potential to, and usuallydoes, produce much more power than engines twice its size. However, withdisciplined drivers, it does not loose the fuel economy characteristics inherentwith small, normally aspirated engines when the turbo is not in use. The VNT-25combines the responsiveness of a small turbo with the efficiency and performanceof a much larger turbocharger. Simply stated, the VNT-25 is the idealturbocharger. It allows great power almost no tur bo lag, great responsiveness,retains engine and compressor efficiency, and allows excellent turbine controlfrom boost creep. BibliographyRalph C.
