The impacts of war and innovation on the prophetically calamitous sort Essay The prophetically calamitous sort focuses on topic of expectation of debacle or notice of ruin in future, including across the board annihilation and demolition. A dangerous atmospheric devation can be a genuine case of prophetically catastrophic situation. Truth be told man fears himself and all the more so what he has made. War is a debacle of man’s activities that has consistently effectsly affected his life. With progression of innovation, war has taken a step higher as is the damaging impacts which are to be accounted by modern weapons utilized. This is contrasted with the dread of divine beings as in the Greek culture of fifth century in Athens (Ford 72). In those time one couldn't resist the divine beings and prevail in their undertakings in light of the fact that guided by hubris, one met destiny the individual in question was ordained, as delineated in the old style scholarly works. Heavenly powers The divine beings spoke to the celestial forces controlling destiny of man. Sophocles presents these forces of the divine beings in sensationalized play in the account of a man accidental drawing nearer to the miserable destiny he has been all along battling relentlessly to maintain a strategic distance from. The youngster Oedipus is destined to an illustrious couple, Jocasta and Laius yet a dismal prediction deny this kid the imperial childhood. Outcasted to be slaughtered Oedipus is safeguarded and raised by Corinth King. As he grows up the issue of his genuine guardians comes up and Oedipus looks for the prophets to know reality with regards to his folks (Markantonatos 26). The journey to know his genuine guardians in Corinth takes him to prophet Delphi who revealed to him he would murder his dad and lay down with his mom. Oedipus leaves Corinth however in transit murders a more interesting his dad in light of his pride and obliviousness. Had he been aware of what the prophet had let him know? He ought to have evaded all encounters like that at the junction and would not have capitulated to executing. His examination to know the enemy of King Laius embodies the stature of his numbness as he blames Tiresias for lying for the benefit of Creon, his incredible adversary for authority of Thebes (Markantonatos 39). Oedipus reproaches Tiresias for his absence of sight however it turns out, he himself is ignorant concerning reality. At the point when reality occurs to him he is irate to such an extent that he gouges out his eyes. The hubris and hamartia are accomplished is this play as Oedipus, through his pride and obliviousness, guided sovereignty to realize reality prompts his destiny, and draws the perusers compassion. In spite of the fact that the perfect forces are accused for what befallen Oedipus quite a bit of his obliviousness is ascribed to hubris which presents to him the calamity that comes upon on him. In Oedipus at Colonus, Sophocles delineates the finish of the deplorable hero’s life and his mythic ramifications for Athens. Oedipus experiences the change from a miserable bum, outcasted from his city as a result of his deeds, into a character of huge force, capable of expanding divine favors. Markantonatos (39) advises us that the play communicates the Greek folklore conviction of heavenly powers that characterize the fate of man. Oedipus and Antigone look for shelter in Athens after they are exiled from Thebes. A contention emerges in Thebes where Creon and Eteocles, Oedipus’ child need Oedipus to return in Thebes to favor them to keep away from a revile anticipated by the prophet. Oedipus welcomes Polynices with the scourge of shared fratricidal murder. As the play parts of the bargains been satisfied for Polynices and Eteocles are occupied with fight where the prediction of the revile is satisfied as they execute one another (Ford 51). The impacts of war for this situation prompted the demise of siblings and revile completes the entire family. As indicated by Ford (59) the divine beings in antiquated Greek culture of fifth century B. C were dreaded due to the impact over the lives of the individuals for predetermination could be molded in the discipline of ones sins and the discipline went ahead ones life and generally at the stature of achievement which was all the more humiliating. On reacting to the lives of the characters in Oedipus at Colonus shows war has on welcomed deplorable consequences for the life of man. Because of his war-like mentalities, Oedipus murders his dad and the revile is satisfied in his life where he moves from elegance to grass and his ancestry likewise falls due to war. This in spite of the fact that point on the heavenly powers at work, war has been brought by the characters hubris and hamartia which adds to destroying impacts on their lives in satisfaction of the forecasts of the prophets. War and the powerful powers in prophetically catastrophic type have by and large added to the fiascoes that influenced the Greek society. Man can just wonder about the miracles and fears brought by the celestial powers at work yet war is his creation and can be kept away from by selecting to understand the current issues genially. Had Oedipus been quiet after the oracle’s Delphi forecast, he would have discovered reality that the expected guardians in Corinth were not his genuine guardians. His resentment at the intersection made him execute his genuine dad in spite of the way that it had been forecasted that he slaughter his dad (Markantonatos 60). Had he controlled his displeasure would he have stayed away from the satisfaction of the prediction on him? Much is accused on the divine forces of man’s predetermination yet what is clear is man drives himself to his destiny. Is it conviction that leads man to his devastation or is it totally with respect to the otherworldly powers? Man can on his part forestall what is befalling him by practicing alert and attempting control his activities that carry fiasco to him. Impacts of war and innovation The impacts of war and innovation in the realm of writing are sensationalized in sci-fi which makes man scared of his own creation. On the planet today numerous wars are being encountered that effectsly affect the lives of individuals. As indicated by Wells and MacAdam (37) the innovation of man has prompted the assembling of the most complex weapons the world has ever seen. Instances of these weapons utilized against humanity have created tragic and mass passings that have stunned the world and might take numerous years to overlook the Holocaust of Jews and the Hiroshima. In real portrayal of these impacts in prophetically catastrophic class has left man think about what the innovation and war can bring to man: mass passings and impacts that undermine man’s presence. This has been exemplified sci-fi books and created in motion pictures that have been contacting and exciting to the mystic of man. The War of the Worlds H. G. Wells’ The War of the World is a showstopper abstract work itemizing the impacts of innovation and war on man. The book brings out subtleties of the British open country and a city under attack and Wells prevails in the manner he delineates the arrangement of occasions in the drama disaster which is fun yet leaves the peruser with something to consider. The epic relates the importance of attack and for this situation outsider from different planets. The outsiders are more equipped than individuals could have envisioned with deadly weapons that compromise life on earth. Presumption is to be faulted for additional outsiders land on earth and more destruction increments brought about by the outsiders (Wells and MacAdam 40). The picture portrayed by the storyteller of individuals escaping the city is truly stunning for it focuses with the impacts of war which are anticipated to cause dislodging of individuals and decimation of properties. Because of exercises of war mental soundness is lost and the world goes distraught over the impacts floating ashore. Everything is in free for all as individuals attempt to fend off the hazard undermining people’s lives, and luckily the outsiders surrender to presentation to normal earthbound microbes. Translation of The War of the Worlds In prophetically catastrophic class, the work predicts the result of future occurrences that effectsly affect lives of the individuals. The War of the Worlds predicts the utilization of modern weapons that can cause mass passings as portrayed by the intrusion. It may not occur as anticipated however the proceeded with progression of innovation on weapons we may in future experience wars that utilize these weapons, carrying devastation to similar individuals who made similar weapons (Wells and MacAdam 28). Therefore man must be concerned not of the old divine beings and the powerful powers as delineated in the traditional Greek plays, but since of his activities to make weapons by means of the cutting edge innovation. Supranational concessions to the expansion of weapons of mass pulverization are today being fixed to stay away from the wars these weapons might be utilized. In any case, for to what extent will these understanding hold before defaulters rise and these weapons arrive because of fear based oppressors? To what extent before countries begin ascending against one another? These are the feelings of dread man has of weapons he has made and what impacts they can have to the world. In the Greek culture, man stressed over the divine beings and how they influenced his life, yet man today is progressively stressed of the wars and innovation that has empowered him make weapons which effectsly affect life (Wyndham and Francis 98). Not to state that divine beings don't impact his life yet essentially in light of the fact that he has comprehended his activities are to be faulted for the tenderness and maudlinness occurring for on him. The Day of the Triffids John Wyndham sci-fi delineates an existence where man needs to battle against the chances to overcome the truth that is eliminating people into annihilation. A plague is out to wipe humankind and just two individuals are staying normal on the world: Bill and Josella. The people group is being eaten up to annihilation by mix of the triffids which are meat eating man made plants that can walk, talk and are in upheaval to take up the world from man. Truth be told the seeds of the plants have spread far and wide after a plot to take them from Russian research center (Wyndham and Francis 81). Bill at last meets Josella whom they had been isolated however need to fend off the triffids which are ending up being flexible. Wyndham epic is about what may be clarified as the obstructing fate of human race behind

The Secret to Writing a College Admissions Essay That Stands Out from the Crowd

The Secret to Writing a College Admissions Essay That Stands Out from the Crowd If youre in the process of writing a college admission essay, youve already had a taste of the anxiety these types of assignments can cause. While choosing each word carefully, your mind probably spins with a series of questions: Will this essay keep me from getting in? Will they find it boring? Does it stand out from the crowd?Added to that anxiety are the often complex, or just plain strange, questions that many colleges will ask, like Do you believe we are alone? or How do you feel about Mondays? Whether the question is strange or difficult, overly simplistic or not even applicable to your lifeâ€"here are some quick tips on the secret to writing a college admissions essay that stands out from the crowd of other essays the admissions committee will read along with yours.Less is moreMany colleges will give you a word count maximum but for the ones where a word count minimum is given, dont take that as an invitation to write over 800 words. The admissions committee who will be readin g your essay(s) will also be reading a stack of other essays, and will not want to spend more time reading yours than necessary. Keep it concise to maintain their interest without taking up a lot of their time.Uniqueness countsThe key to writing an essay that stands out from the others is to be as unique as possible. While this might be a difficult task for many soon-to-be college freshmen, its worth your time and effort to think of somethingâ€"anythingâ€"that makes you unique compared to the others. Maybe its a travel experience, a family history, a goal, a way that you think or something youve done?Dont cover everythingIf youve led an especially busy life as a high school student, dont try to cover everything youve done. Pick the highlightsâ€"the activities that were the most rewarding or the most impressiveâ€"and stick to those few things. If you write about 20 different activities within the span of a 500-700 word essay, your writing will inevitably appeared scattered and unorga nized. Its simply impossible to write about that many topics with that limited of a word count and keep it organized.Be controversialMany people falsely assume that you should avoid topics such as religion, politics and the like in college entrance essays, but this couldnt be farther from the truth. Although you should avoid soapboxes and topics that might be against school philosophy (if applying to a religious-oriented school), voicing your stance and providing reasonable arguments for it and against it shows that you know how to think logically and coherently about important topicsâ€"a trait that you will need to succeed as a college student.Avoid mistakes in grammar, punctuation and spellingWhile this should be obvious, you would be amazed at how many students submit essays with glaring grammar, punctuation and spelling mistakes. The main reason for this is they depend on their word processors spelling/grammar check, which will not catch many of the mistakes that a flesh and blo od editor would catch. Submitting an essay with these types of mistakes is a guaranteed way to get your application rejection. The admissions committee will believe (and rightly so) that if you have errors on what should be an example of your best work, your daily work in college will have even more errors. When they compare an essay with errors to an essay without them, and have to choose between the two, its obvious which one they will choose. And it wont be yours.Be accurateI am consistently amazed at the number of college admissions essays I receive that refer to particular works or authors, and then get those titles and author names wrong. While a good editor will hopefully catch such errors, its impossible for an editor to know about every topic and every author. For this reason, beyond the mistakes that can be made with spelling, punctuation and grammar, a big mistake that many applicants make is inaccuracy of information. When referring to a particular author who was an infl uence on your life and choices, be sure to get the name of the author and title of the work right. When discussing theories, research, or any topic for that matter, be sure that you are completely accurate in the context and use of this information. Otherwise, youll seem as if you dont know what youre talking about and are just throwing out information that youve neither studied nor learned.Be descriptiveWhen youre discussing something that youve accomplished or situations in which youve excelled, be descriptive because it lends a sense of credibility and humaneness to what you are saying. This is not to say that you should overload an essay with adjectives and adverbs, but adding details like this will make your writing more exciting and more vividâ€"two traits that admissions committees love in an essay.Be likeableThis one is perhaps the most important, as long as your grammar, spelling and punctuation are correct. When an admissions committee reads an essay written by a student w ho has excelled much in their high school years but seems pedantic, stuffy and just plain boring, that student still has a chance of being denied admission. College is as much about social interactions as it is about academics. If you fail to show that you can be likeable and fit in well with the college community, you have missed an opportunity to make your essay stand out from the rest.

Essay on Arnold Friend - 669 Words

Arnold Friend Arnold Friend is a seductive man, or should I say ArN OLD FrIEND with a dark appearance hiding something deeper, something evil? Arnold, posing as a teen-age boy, is none other than the devil himself, which shows in his words and actions, and in his physical traits. From the very beginning of, Joyce Carol Oates, Where are you going, Where Have you been? a certain number of religious references are interspersed throughout.

He is a short man who in order to stand erect; he must push his shoulders back. At one point, Friend removes his glasses, and reveals his eyes which #8230;were chips of broken glass that catch the light#8230; (Oates 474). Friend has a mask-like face that stops when it reaches his neck, almost as if it is painted on to his head. Whenever Friend speaks, his words seem to come out in a singsong style sounding as if he were repeating the lyrics of a song. There are two specific details in this story that lead someone to believe Friend is an evil man. The first one is the way his boots turn almost as if his foot is not even in it. Marie Urbanski states that his feet resemble the devils cloven hooves, which explains why his feet do not fit into the boots properly (403). The other detail is the fact that Friend has a muscular neck. Often times this suggest the reptillian, as does the fact that he slid rather than stepped out of the car (Urbanski 403). In this last statement, Friend is being portrayed as a snake, which is often meant to be a symbol of evil, or the devil himself.

Global Warming And Climate Change Essay - 1399 Words

One of the biggest debated issues today is that of anthropogenic global warming or climate change. People will argue that the earth goes through a natural cycle of warming and cooling. While this is somewhat true, the majority of what we are seeing currently is something beyond natural causes; something caused by humans. Humans produce a massive amount of waste, and air pollution is no exception. The amount of greenhouse gas emissions has only continued to rise due to population growth- which leads to an increased demand for resources, products, and industrialization. Greenhouse gases are a global issue with very potential harmful effects on ecosystems, biodiversity, the environment and the well-being of people worldwide. What is unknown to most is that livestock’s contribution to the environmental issues are massive, and its influence to the solution is just as substantial. Many people would name transportation as the biggest contributor to air pollution and greenhouse gas emissions, but it s actually beaten by animal agriculture by a long shot. Two environmental advisers to the World Bank, Robert Goodland and Jeff Anhang, wrote a 19-page report on the topic. Through their research, they claim that livestock and their byproducts account for at least 32,000 million tons of carbon dioxide (CO2) per year, or 51 percent of all worldwide greenhouse gas emissions.

Membrane Physiology Essays - Membrane Technology, Membrane Biology

Membrane Physiology Introduction The cell membrane is a fluid structure that is made up of phospholipids and proteins. Its main function is to allow osmosis and diffusion to occur in a cell. It protects a cell from taking in molecules that are too large and other chemicals that are not permeable without energy being used. The cell membrane is considered to be selectively permeable because it does not allow the non-fat soluble chemicals and the larger molecules in, but it does allow fat soluble chemicals and small molecules to pass into the cell. In order for the larger molecules and non-fat chemicals to enter the cell protein channels and energy are needed. In this lab you will see the cell membrane working. The experiment will show the Osmosis of water and a sucrose solution. Osmosis is net movement of water molecules from a high to low concentration until equilibrium is reached. In other words, Osmosis is the diffusion of water. Through the diffusion of water Isotonic solutions may occur. This is where both sides of the membrane have an equal amount of water. There may also be a Hypertonic solution. That is where the membrane has more water and the concentration will move down a gradient causing the membrane to shrink. Another solution that may occur is a Hypotonic solution. This type of solution allows the water molecules to pass through the cell membrane into the solution causing the cell to increase in size. Diffusion of dye in agar and water will be studied in this lab. Diffusion is the movement of a concentration from a high gradient to a lower gradient until area is at same level. We will also study the permeability of the cell membrane when different solutions are used inside and outside of the cell. In this lab, we will observe the changes taking place during the diffusion of dye through agar gel and through water. We will determine what type of solution is formed when placing the mock cell membrane in different levels of solution. We will calculate the rate at which the dye diffuse d and plot the findings in a chart to show the different rates each cell changed. Hypothesis In Part A of the lab the cell membrane of bags 2 through 4 will gain mass because of the use of sucrose solution in the cell. The water will move through the dialysis tubing to form equilibrium between the membrane and outer concentration. Bag 5 will be a Hypertonic solution, the water is at a high gradient and the solution surrounding the cell is at a low concentration gradient, causing the bag to shrink. Bag 1 will have an Isotonic solution. In Part B of the lab, the potassium permanganate will diffuse faster in water then in the agar gel. In Part C of the lab, the solutions in the bag and the solutions around the bag will be the same after the testing is done. Starch, chloride, protein, and sulfate ions will be found in both areas tested. Materials and Methods See the attached sheets for materials and methods used. Results Part A: In bag 1 the mass changed 1/10 of a gram. In bag 2 the mass changed 4.4 grams. In bag 3 the mass changed 6.3 grams. In bag 4 the mass changed 8.3 grams, and in bag 5 the mass changed to a negative 6.0 grams. Part B: The methylene blue diffused through the agar gel a total of 4.5 mm and the potassium permanganate diffused 10.5 mm. The potassium permanganate diffused through the water a total of 15 mm. Part C: The solutions in the bag contained starch, which caused the solution to turn black. Sulfate ions and proteins were not found. Chloride ions were found in the solution, the solution turned into an orange-milky color. The solutions in the beaker contained no starch. There were sulfate ions found, which caused the solution to have white particles floating in it. Chloride was found in the solution, the solution turned into a yellow color. The beaker also contained proteins, the color of the solution turned to a violet color. Discussion and Conclusion The findings for Part A backed up my hypothesis. Bags 2 through 4 did have a Hypotonic solution. The 5th
