Castles Essay -- essays research papers fc

The castle, a strong rock structure, which invokes images of kings and knights, dragons and princesses, is such an integral part of medieval history. One cannot think history without thinking about the towering structures of stone that dominated the green landscapes of the past. These stone monoliths served many purposes buildings of government, defense, symbols of power, and homes. Just as it has varied purposes, the castles diverse and interesting history, from tiny wooden structures to the behemoth structures of rock and mortar that we harmonise with the word Castle.The castles development cannot be pinpointed to a particular year or location, though the first castle is widely accepted as being Dou-la-Fontaine and Langeais in the Loire Valley of France. Both these castles were originally stone fortifications that served as homes to local warring Counts. As time went on and their feuding got more violent, their homes got more impressive, apiece count adding levels and stones to their homes. This one-upmanship continued until, at some point, the homes became what is considered the first castle, the motte and bailey.The Motte and Bailey Castles started out simple, normally just wooden buildings, which relied on natural defenses such as rivers or hills to hamper attacks. Oft times rivers were even diverted to add extra protection, and as a steady water supply in the event of a siege. still always somebody had to do better soon they were adding mounds, banks ditches, and whatever else would trip up invaders. Earthworks, as they were called, could be mounds, also called mottes, or hollow circles of dirt, called ringworks. In the shimmy of a motte, a wooden tower usually topped it while a ringwork enclosed structures protected by a wooden palisade, or fence. Nonetheless, in each instance, earth was dug from the perimeter, leaving a ditch, which further impeded attackers. Eventually these two types of earthworks were combined into one castle, the traditional Motte and Bailey. Baileys being a prominent level area surrounded by a ringwork, with a Motte connecting. The bailey often contained a hall, buildings for livestock, a forge and armory, and a chapel. The Motte and Bailey castles were also very quick and on the loose(p) to construct, and provided a look-out post, in addition to, ad... ... proceeded at a more leisurely pace, becoming more of a hobby than a necessity. However, there were times when a castle or two discouraged an invading force or to quell a rebellious population. These changes in society gradually led to the regrets of the castle as an institution. Where castles had once served an important position as a fortress, city hall, and home, these functions were now being better served by other buildings at rock-bottom costs. Nobles tired of playing the my castle is bigger game and searched elsewhere for more comfortable homes. And forts manned by professional soldiers assimilated the duty of defending areas. Luckily, so me castles remained, fortune as a centre for local administration or as prisons long after they had ceased being cool.

Role Playing and Control in A Doll’s House Essay -- Dolls House essays

This essay will explore the issue of roles, or game playing, in A Dolls House. This concept is one key to approaching the play, and particularly Noras role. Let me further make the observation that one crucial cistron in the roles Nora plays is that she needs to be in check out, to take the lead role, as it were, employ other people either as supporting actors or reference and that she writes her own script.This notion helps me to deal with a question which frequently arises here How can one woman make so some unexpected transitions? How is it realistic for the child-wife to play the adult female tease (with Dr. Rank), the capable determined businesswoman (in her secret dealings with the debt), the frantically desperate woman thinking of suicide, and, above all, the coldly single-handed mature woman at the conclusion of the play? Well, one common feature these manifestations of Noras character all suffer is that they enable her to control others, to assert herself without in truth attending to, listening carefully to, learning from, or acting on what other people say.Consider for a moment why Nora would not have told Torvald long ago about the debt. The reason she gives is interesting she doesnt need to at this point in her life--shes young enough and pretty enough to exert her control over him in other ways (and telling about the debt would shatter her image as the clueless but sexy child-wife). However, she is looking forward to using that event in the future, when she can no longer rely upon her looks. How exactly this would help restore his affections may not be clear, but there is for certain a sense that Nora hopes it will make her more important to him. The fact that Nora thinks of her relationship with Torvald in ... ...d she did it (society be damned). Moreover, the hard disciplined work over many years necessary to repay the loan is a tribute to Noras determination and skill in carrying out her own project, all the while sustaining her own coupling in quite another role.This quality lies at the heart of Noras heroic character. Her confidence in herself, in her abilities to control the situation, to solve the problem, has led to her success and has confirmed, in her eyes, that she is right. She flouted societys laws, worked hard, and is now about to reap the success of that action by handing over the final payment. It has not been easy, and there are times when a certain tension shows through (as in that mention of the word Damn), but theres no sense that Nora feels that she has been compelled to act in this way, that she has not freely chosen to be the psyche she is.

Cyberpunk Definitional Paper -- Science Fiction Definition Essays Pape

cyber-terrorist Definitional PaperIn the late 1970s and early 80s and new caseful of writing style came about that relied on many of the traditional criteria to be called recognition fiction, but had a certain something else that had many people agreeing that it was not and science fiction. This new style of writing was so different and so many people started writing in this style that the general public immovable that it was time this genre of writing deserved a label cyberpunk. Cyberpunk is not an elementary group of writing to define on paper, but it is easy to spot when one is reading it. The cyberpunk writing movement started out with many short stories then became recognizable to the masses with probably the movements most productive novel, entitled Neuromancer. William Gibsons novel was the first major work to get recognised from this category, it seemed to set the precedence of what cyberpunk included, and what a piece of writing needed to find to get labeled cyberpun k. Cyberpunk does not define the works that are in it, rather, the works define what cyberpunk consists of.Since William Gibsons Neuromancer was one of the first to be recognized as cyberpunk, the genre can be easily defined by the aspects set forth in his novel. Neuromancer was clearly sci-fi, but it included many points that representative sci-fi had never dealt with this is what cyberpunk can be defined by. Bruce sterling said in the preface to his anthology Mirrorshades its possible to make broad statements about cyberpunk and to strand its identifying traits(ix), and all of them are exemplified in Neuromancer. One of the most distinctive features of cyberpunk is the technological aspect. Traditional science fiction dealt with things that were possible, bu... ...roup, but it is even harder to define since it is considered to be within the larger group of science fiction. Cyberpunk has almost become a way out for critics to define these writers. These writers are science ficti on, but since they do not always deal with the values and ideas brought forth by the traditional science fiction writers, the critic will pass it off as being cyberpunk. While the label cyberpunk will take these works, the label itself grows and changes with every work that is added, making cyberpunk a broader, more open category and harder to define. Cyberpunk does however hold on to its original values that include what can be considered a human factor to set itself apart from traditional science fiction.Works CitedGibson, William. Neuromancer.

With this, the politicians tend to focus on such issues and controversies, rather than solving the states problems regarding the governments inefficient services. Following this is the failing value of dollar. As a result of this, the economy of US is under a critical condition. If not solved, this may ask their domestic and international trades. The prices of services and goods may also increase, that may result to revolutions or the failure of the standard of living of the Americans. When this happens, it may cause the less battle of their market to foreign trade. The fifth problem I considered is the lack of preparedn ess and actions for cancel disasters. The whole planet is under climate change and the people are not aware of what is it all about. The natural disasters now and stronger and are not detected and reported accurately. One example is the typhoon that hit a state in US wherein hundreds of people died and the government was unprepared, so the rescue operation and the services were of low quality.Not only that, the spread of information and educating the people about natural disasters is very minimal. Next is the poor control of government spending. Like the war in Iraq which cost them millions of dollars, but they failed to give justice to both sides. Also the bullion they provide for space exploration in order to compete with other countries that are advancing in that field like Russia. Another is the fund for war weapons which are not rationally used, and gives high risk to the citizens security and health. The seventh problem on my list is the human rights violation abroad brought by the wars launched during Bush administration. The war violated the human rights of almost all the population consisting Iraq. Its effects are long term because it has caused and American citizens residing in Middle East can be in danger for attacks as the result of the war. Next is the lack of help in restoring the environment which is I think is connected with the issue on lack of preparedness.This is a problem because the whole planet is experiencing climate change, and given that US is a first world country and has a high function in the worlds pollution, I think they should launch programs and lead other countries in restoring mother nature. The ninth on my list is the problem at bottom family relations. There is an increase in the number of partners getting a divorce, though they have institutions to help these families, still it makes their moral standards low since children of broken families are the victims. The travel problem is the illegal aliens inside their territo ry that may cheat taxes and commit crimes causing another set of problems to the nation.ReferencesThe Real Problem Facing America.

W.H. Auden speech

Aden was not only a great poet during his life but an author as well as a playwright. An Interesting fact or so Aden was that he was most well-known for his Hamilton-like ability to write poems in almost every verse form. This talent was one of the numerous reasons that he will be remembered as one of the surpassing literary influences in the 20th century. Sense of Loss He has left behind a legacy of work that has the ability to touch on and give written account to thoughts and emotions that, at times seem too difficult to express in our own words.One such time would be at a funeral, where one would be hard pressed to convey their emotions in a way that is recognise but beautiful in the way that it is conveyed. I would believe it is only proper to quote a portion of Addends own poem hat deals at one time with this subject its title being Funeral Blues. He was my North, my South, my East and West, My working week and my Sunday rest, My noon, my midnight, my talk, my song I though t that love would last forever I was wrong.The starts are not wanted now put out every one, Pack up the moon and dismantle the Sun, Pour away the ocean and mop up the wood For nothing now can ever come to any good. Humorous stories/ Recollections In High school, many of us were, to put it bluntly, forced to read meter that all in all seemed boring, dealt with feelings and meanings we didnt care to comprehend ND had a rather gloomy or outright obsessive focussing on love and relationships.I was one of those people who rather hated reading poetry and verse like Romeo and Juliet let alone spending an entire ground level trying to discuss the deep meanings pertaining to love and things of the like. Love Is great and all but does poetry about It need to be so Enter the poetry of W. H. Aden as a lovely shot of reality in the world of poetry on the subject of love. There is a quote from Aden that seems to summarize short his approach to poetry, specifically poetry pertaining to love . Thousands have lived thou love, not one without water. This quote not only summarizes his approach but his tone with his poetry about love as well as other topics. Addends ability to write about love without breaching the wall of dreamed fantasy or idealistic flawlessness is what truly set his apart. While love is important, as any emotion is, it is not a life sustaining forces as many Romantic poets writings would lead people to believe. It is in his poetry that Addends dry, blunt and sometimes sad sense of humor would shine though. Perhaps some found it a little singular and difficult to understand as humor, but it was uniquely him.Encourage the Living W. H. Aden was an artist the likes of which only comes around once in a great while. Even though he is no longer with us we can still experience him finished his words and ideas. Through the ages his poems will continue to inspire people through his unique approach on poetry topics and humor. His poems have helped many to see R omantic poetry in a different light and with a more than realistic view point and a bit of humor. In closing I would like to leave you with one of his quotes, We are all here on Earth to help others what on Earth the others are here for, I dont know.

The Influence of Temperature in the Forward Osmosis Process

Chapter FourMathematical ModelChapter FourTHEORETICAL ANALYSISMA andMathematical ModelingPurpose of the survey is to probe of temperature as a factor that influences the transport of water system across the tissue layer in FO procedure. The steady-state theoretical fibs have been developed to foretell water iux (JouleTungsten) as map of temperature (Thymine) and bulk constriction (C) ( i.e. Draw and Feed absorption ) . It was anyways study the consequence of temperature on some belongingss, such as Solute distribution coefficient (CalciferolSecond) , Mass f are coefficient (K) , Permeability coefficient (A) and Solute electric automobile resistance (Km) .4.1 Osmotic PressureThe osmotic burden per unit area (?) of a root word depends on the assimilation of dissolved ions in solution and the temperature of solution, and fanny be computed by utilizing Va nt Hoff comparisonWhitherNis the vant Hoff factor ( histories for the figure of single atoms of a compound dissolved in the solution ) ,?is the osmotic coefficient,Cis the torpedo parsimony ( molar concentration ) of the solution,Roentgenis the gas invariable andThymineis the absolute temperature of the solution. The vant Hoff factor is introduced to cover divergences from apotheosis solution behaviour that include bounded volume occupied by solute molecules and their common attractive voice suck as in new wave derWaals attractive military force ( Howard, 2003 ) . Table 4.1 show osmotic coefficients (?) for a figure of solutes of physiological importance ( Khudair, 2011 ) . For all solutes?depends on the substance and on its concentration. As the concentration of any solute attacks zero its value of?attacks 1. In ideal solution,?= 1 ( Glass tone, 1974 ) .Table 4.1 Osmotic Coefficients (?) and Vant Hoff Factor ( N ) for a Number of SolutesSubstanceVant Hoff Factor (N)OsmoticCoefficients ( ? )NaCl20.93KCl20.92HCl20.95New hampshire4Chlorine220.92NaHCO320.96CaCl230.86MgCl230.89Sodium2So430.74MgSO4 20.58Glucose11.01Sucrose11.024.2 Concentration Polarization4.2.1 orthogonal Concentration PolarizationConcentration polarisation ( CP ) is the accretion of solutes near the tissue layer out and has inauspicious effects on membrane public presentation. The iux of water supply through the membrane brings feed H2O ( incorporating H2O and solute ) to the membrane surface, and as clean H2O iows through the membrane, the solutes accumulate near the membrane surface. Equations for concentration polarisation run on be derived from i?lm theory and the great unwashed balances. Harmonizing to i?lm theory, a spring bed signifiers at the surface of the membrane. body of water and solutes move through the enclosure bed toward the membrane surface. As H2O base on ballss through the membrane, the solute concentration at the membrane surface additions. The concentration gradient in the boundary bed leads to diffusion of solutes back toward the volume nourishment H2O. During uninterrupted operation, a steady-state status is reached in which the solute concentration at the membrane surface is changeless with regard to clip because the convective iow of solutes toward the membrane is balanced by the diffusing iow of solutes off from the surface.A caboodle balance can be developed at the membrane surface as followsMass accretion = mass in ? mass out ( 4.2 )With no accretion of mass at steady province, the solute iux toward the membrane surface must be balanced by iuxes of solute iowing off from the membrane ( receivable to diffusion ) and through the membrane ( into the fall into place ) as followsWhereMeteris mass of solute,Jouletungstenis the experimental permeate H2O magnetic combine,Tis clip,CalciferolSecondis the diffusion coefficient of the solute,omegathe distance perpendicular to membrane surface,Cpeis the solute concentration in the permeate andEis the surface country of membrane. Equation 4.3 applies non hardly at the membrane surface but besides at any plane in the boundary bed because the net solute iux must be changeless throughout the boundary bed to forestall the accretion of solute anyplace indoors that bed ( the start term in equating 4.3 represents the solute that must go through through the boundary bed and the membrane to stop up in the permeate ) . Rearranging and incorporating equation 4.3 across the thickness of the boundary bed with the boundary conditions C ( 0 ) = CMeterand C ( ?Bacillus) = CF, cell, where CF, cellis the concentration of provender cell solution and CMeteris the concentration at the membrane surface, are done in the lowmentioned equationsIntegration outputsWhereKis the mass conveyance coefficient and?Bacillusthickness of the boundary bed, rearranging the equation 4.6 when utilizing the vant Hoff equation the eventually theoretical account from the concentrative external concentration polarisation at each permeate flux, could be calculated utilizingWhere?F, Bis the osmotic force per unit areas of feed solution at the majority and?F, mis the osmotic force per unit areas of the provender solution at the surface membrane. Note that the advocate is positive, he pointed out that ?F, m& A gt ?F, B.The get in solution in touch with the permeate side of membrane is the being diluted at the permeate membrane interface by the permeating H2O ( gloomy and Kessler, 1976 ) . This is called diluted external CP. Both dilutive external CP phenomena cut down and concentrative the effectual osmotic drive air force. A dilutive external CP modulus be identified as above, merely In the present instance, the concentration of the majority greater than concentration of the draw solution at the membrane surface ( i.e. ?D, B& A gt ?D, m) ( Cath et al. , 2006 ) Where?D, mis the osmotic force per unit areas of the draw solution at the membrane surface and?D, Bis the osmotic force per unit areas of draw solution at the majority. The general equation portraiture H2O conveyance in FO, RO, and PRO i s ( Cath et al. , 2006 ) Where,Athe H2O permeableness invariable of the membrane, ? the contemplation coefficient, and a?P is the applied force per unit area. For FO, a?P is zero for RO, a?P & A gt a?? and for PRO, a?? & A gt a?P ( see figure 4.1 ) .Figure 4.1 Direction and magnitude of H2O as a map of ?P.To pattern the flux public presentation of the forward osmosis procedure in the presence of external concentration polarisation, we start with the flux equation for forward osmosis, given asWe assume that the salt does non traverse membrane, the osmotic contemplation coefficient (?) , assume equal 1. Equation 4.10 predicts Flux as maps of driving force merely in the absence dilutive external concentration polarisation or concentrative, which may to be valid merely if the permeating flux is excessively low. When higher flux rates, must be modified to include this equation both(prenominal) the dilutive external concentration polarisation and concentrativeFigure 4.2 ( a ) show s this phenomenon with a muddy symmetric membrane ( McCutcheon and Elimelech, 2006 ) .4.2.2 Internal Concentration PolarizationIf the holeyness support bed of asymmetric membrane confronting feed solution, as is the instance in force per unit area retarded osmosis ( PRO ) , Polarization bed is established along interior of heavy active bed as H2O and solute propagate the porousness bed ( Figure 4.2 ( B ) ) . This is referred to as concentrative internal concentration polarisation, this phenomenon is similar to concentrative external concentration polarisation, except that it takes topographic point within the porous bed, and therefore, can non be underestimated by cross flow ( Lee et al, 1981 ) Obtained look patterning this phenomenon in force per unit area retarded osmosis ( Loeb et al. 1997 ) . This equation describes internal concentration polarisation ( ICP ) the effects and how it links to H2O flux, salt permeableness coefficient ( B ) and H2O permeableness coefficientWhereK mis the opposition to solute diffusion within the membrane porous support bed,Kmis defined asWhereSecondthe membrane structural parametric quantity,?mis the thickness,?is the tortuousness and?is the porousness of the support bed,Kmis a step how easy it can be dissolved widespread support inside and outside Layer, and hence is a step of the strength of ICP. We maintain the usage of theKmterm due to convention established in old surveies on internal concentration polarisation. Salt permeableness coefficient ( B ) is about negligible compared with the other footings in the equation 4.12. Therefore, we ignore salt flux in the way of H2O flux and any transition of salt from the permeate ( draw solution ) side ( Gray et al. , 2006 ) . Therefore, flux can be solved for implicitly from equation 4.12The exponential term in equation 4.14 is the rectification factor that could be considered the concentrative internal concentration polarisation modulus, defined asWhere ?F, Iis the osmotic forc e per unit area of the feed solution on the interior of the active bed within the porous support. The positive advocate indicates that ?F, I& A gt ?F, B, or that the consequence is concentrative. Substitute Equation 4.8 into 4.14 to obtain an analytical theoretical account for the impact of internal and external concentration polarisation on H2O fluxAll the footings in equation 4.16 are readily determined through computations or experiments. From equation we can cipher the flux of H2O through the membrane where feeding solution is placed against asymmetric support bed and the draw solution on the active bed.In forward osmosis applications for desalinization and H2O intervention, the active bed of the membrane faces the provender solution and the porous support bed faces the draw solution ( Kessler and Moody, 1976 ) . As H2O permeates the active bed, the draw solution within the porous infrastructure becomes diluted. This is referred to as dilutive internal concentration polarisati on ( Figure 4.2 ( degree Celsius ) ) . ( Loeb et al, 1997 ) Descriptions likewise flux behaviour in the development of forward osmosisWhen presuming that B = 0 ( i.e. , the salt permeableness is negligible ) and the equation 4.17 is agreement, are acquiring an inexplicit equation for the flux of H2O permeatingHere, ?D, Bis now corrected by the dilutive internal concentration polarisation modulus, given byWhere ?D, Iis the concentration of the draw solution on the interior of the active bed within the porous support. The controvert advocate because the H2O flux is in the way off from the membrane active bed surface, In other words, the concentration polarisation consequence in our instance is dilutive, intending that ?D, I& A lt ?D, Bby replacing equation 4.7 into 4.18, we getThe footings in equation 4.20 are mensurable system conditions and membrane parametric quantities. Note that here dilutive internal concentration polarisation is coupled with concentrative external concentra tion polarisation, whereas in the equation 4.16, concentrative internal concentration polarisation was coupled with dilutive external concentration polarisation.In each of these instances, the external concentration polarisation and internal concentration polarisation moduli all contribute negatively to the overall osmotic drive force. The negative occasion of each addition with higher flux, which suggests a self-limiting flux behaviour, this implies that increasing osmotic drive force will supply decreasing additions in flux ( hell dust et al. , 2010 ) .Figure 4.2 Illustration of osmotic driving force composes for osmosis through several membrane types and orientations, integrating both internal and external concentration polarisation. ( a ) The profile illustrates concentrative and dilutive external CP. ( B ) PRO manner the profile illustrates concentrative internal CP and dilutive external CP. ( degree Celsius ) FO manner the profile illustrates dilutive internal CP and conc entrative external CP (McCutcheon and Elimelech, 2006 ) .In this be given if taking transmembrane temperature difference into history, the temperature being next to membrane surface will besides differ from that in bulk solution due to the happening of estrus transportation. Hence, utilizing vant Hoff jurisprudence for computation of osmotic force per unit area requires the temperature points to be purely in line with the concentration points asWhereC,TDandTFis the concentration, temperature draw and temperature, with the inferiors F, cell ( feed cell solution ) and D, cell ( draw cell solution ) . The theoretical account to foretell H2O iux can be rewritten to a modii?ed by replacing equation 4.21 and 4.22 in 4.20, we getFigure 4.3 gives the conventional illustration of the concentration and temperature proi?les in FO procedure operated under active bed provender solution ( ALFS ) .Figure 4.3Conventional diagram of mass and heat iux proi?les within boundary bed and membrane duri ng FO procedure under ALFS manner in the presence of temperature difference ( TF, cell& A gt TD, cell) .4.3 Heat FluxHeat transportation from the solution to the membrane surface across the boundary bed in the side of the membrane faculty imposes a opposition to mass reassign The temperature at the membrane surface is lower than the corresponding value at the majority stage. This affects negatively the drive force for mass transportation. Under steady province conditions, derived from the heat balance, the heat transportation in the single compartments of system is represented by the undermentioned equationIn which Q denotes the heat flux, and the inferiors FS BL, m and DS BL represent feed solution boundary bed, membrane and draw solution boundary bed. By stipulating the equation 4.24, we obtainWhereHis the single heat transportation coefi?cient,CPthe specii?c heat of H2O,?tungstenthe H2O denseness.

Graham Greene’s “The Destructors” Essay

Graham Greenes The Destructors is a real-life like story that shows how societal forces or the purlieu shapes the behavior and thinking of the protagonists. Moreover, the story becomes a manifestation of history and protests during a time of despair, dramatically presented by the author.In The Destructors, the protagonists are teens who call themselves Wormsley Common battalion. However, they believe that their innocence is already gone. Their childhood dreams turned to rebelliousness, selfishness, and cynicism in order to favor the worldliness and complexity of the life which society brings them. For an instance, T. disrespected Mr. Thomas and looked upon him with suspicion. He as well as destroyed Mr. Thomas house. They believed that by acting this way, they would be sufficient to achieve stability in their lives. In the 1950s, gangs or organized groups are prevalent in England. They demonstrate the same attitudes and beliefs like the Wormsley Common Gang. Violence and the wave ring society produce these kinds of individuals or groups. Their acts are the results or manifestation of the childrens experiences, socially and emotionally. This literary work is the result of a conscious understanding of the author regarding the situation of England in the early 20th century. World War I occurred in 1914, and it is more likely that England suffered from this war. This suffering is greatly demonstrated in the literature and art during these periods, showing protests to the aggression and melancholy in the society. Short stories are much read to serve the purpose of entertaining or informing its readers. Greenes The Destructors was not only successful in doing this, but he was also able to open the eyes of its readers to the horrid reality of society during war. Moreover, The Destructor becomes a tool that demonstrates how societal forces greatly affect characters in fiction, and people in reality.Works CitedGreene, Graham.

Fiction and Literature Outdoor Literature Essay

When I read great lit, great maneuver, speeches, or sermons, I feel that the gay mind has not achieved anything greater than the ability to sh atomic number 18 feelings and positions through language. - James Earl J matchlesss The major(ip) types of literature across the world be English, Greek, Latin, Roman, African, Indian, American, French, Irish, Spain, Chinese, Italian, Japanese, Persian, Sanskrit, Nepali, Russian and Canadian literature. Literature is a well-considered form of a language that influences the minds of readers of all age.Italian Renaissance is the age of Michelangelo and Leonardo da Vinci, whereas Greece Literature nighly comprises the literature of Greek Gods and Goddesses. Romanticism of Wordsworth is the literature which is oriented towards nature and can be considered to be reverse of classicism. nows era of Modernism and Post modernism uses artificial language ground on ambiguity, jeering and parody. Some originators choose long composition methods t o link more than one written report. Moreover, literature being a part of scientific language is also used to analyze grammar, usage, lexis and semantics. Kinds of Literature Fictional Literature. bid Drama is the theatrical dialog performed on stage, it consists of 5 acts. Tragedy, comedy and melodrama atomic number 18 the sub types of drama. e. g William Shakespeargon, an Elizabethan dramatist composed the plays Hamlet, Romeo and Juliet, King Lear that are storied because of its combination of tragedy and comedy. Problem play, farce, fantasy, monologue and comedy of dexterity are some kinds of drama. Tragedy It is a story of the major character who faces bad luck. Tragedy, elements of horrors and struggle usually concludes with the death of a person. The Illiad and The Odyssey by Homer are the two renowned Greek tragedies.clowning The control character overcomes the conflicts and overall look of the comedy is full of laughter and the issues are handled very lightly. The ele ments used in the comedy are romanticism, exaggeration, surprises and a comic view of life. Melodrama Melodrama is a blend of two nouns aura and drama. It is a musical play most popular by 1840. Uncle Toms Cabin is one of the most popular plays describing cruelty of labor life. It has happy ending handle comedy. Tragicomedy The play that begins with undecomposed mode but has a happy ending is tragicomedy.Prose LiteratureHistory, ledgerism, philosophy, apologue and fantasy writings, scientific writings, childrens literature authors and writers are included in Prose Literature. Myth Myths are the fairy tales with lots of adventure, magic and it lacks scientific proof. Nursery rhymes, songs and lullabies are forms of myths that strike the interest of children. Creative and nature myth are stories of the stars and moon. Magic tales are wonderful tales of quests and fantasy. Hero myths are ideal heroes of adventure. absolutely story The small commercial fiction, true or imaginary, smaller than a novel is known as short story.Short stories are well-grouped that followed the sequence of roaring and no complexity in beginning, concrete theme, some dialogs and ends with resolution. They are oral and short-lived which sop up gossip, joke, fable, myth, parable, rumour and legend. Novel Novel can be based on comic, crime, detective, adventurous, romantic or political story divided into many parts. The major kinds of novels are Allegory The symbolic story revolves around two meanings. What the writer says directly is conglomerationly different from the conveyed meanings at the end. Political and Historical allegory are two forms of Allegory.Comedy Satire is very common form in comedy novels and tries to focus on the facts of the society and their desires. epistolary The collection of letters or mails is the epistolary novels. Samuel Richardsons Pamela and Henry Fieldings Joseph Andrew are the few examples of Epistolary novels. Feminist These types of novels are written by women writers around the world to describe the place of women in a male dominated society. E. g Virginia Woolfs A Room of ones have got. medieval Gothic fiction is the combination of both horror and romance. Melodrama and parody were grouped in the Gothic literature in its early stages.Ironic Ironic novels are known for excessive use of news report technique. It is satire on the contemporary society about cultural, social and political issues. Realism The sincereistic novels are based on the truths of ordinary society and their problems. It focuses on the plot, structure and the characters of the novel. Romance Love and relationship topics are handled optimistically in the romantic novels. It originated in western countries basically the story revolves around love personal matters of main characters. Some popular sub categories of romantic novels are paranormal, erotic, suspense, multicultural and inspirational romance.Narration In narrative style, writer becomes the third person who narrates whole story around the characters. Naturalism Naturalism is based on the theory of Darwin. Picaresque It is opposite to romance novels as it involves ideals, themes and principles that refuse the so-called prejudices of the society. Psychological Its the psychological prospective of mind with a resolution. Satire Satirical novels criticize the contemporary society. The most famous novels are Jonathan Swifts Gullivers Travels (1726), Kingsley Amiss Lucky Jim (1954), George Orwells Animal Farm and Randell Jarrells Pictures from an Institution (1954).Stream of Consciousness James Joyces stream of consciousness is all about the thought coming up in the minds of the readers. A novel also constitutes categories on social and political aspects like proletarian, psychological, protest novel, government, didactic, materialist novel, allegorical novel, novel of engagement, naturalistic novel, Marxist novel, radical novel, revolutionary novel, anti-war novel, utopian novel, futuristic novel, anarchist novel, problem novel, social philosophy novel, novel of ideas, problem play and speculative novel. federation of tribes TaleFolk Tales are traditional stories that have been creating interest since ancient times. The children and old persons like sacred story, magic and fanaticism as well. Fable, tall tales, cumulative, trickster and proverbs are the sub categories of folk tales. Mythology or legend is the ancient religious stories of origin and human civilization such as story of Robin Hood. Types of poetry Poetry is the self-produced overflow of powerful feelings recollected in the tranquility. Greek poetry is found in free verse and we have rhymes in the Persian poem. Are you wondering how to write a poem, here are the followings forms of poem?sonnet Sonnet is the short poem of 14 lines grouped into Shakespearean and Italian sonnets. Ballad The poems that are on the instance matter of love and sung by the poet or group of singers as telling readers a story. plaint This type of poem is the lamenting of the death of a person or his near one. Elegy Written in Country Churchyard by Thomas Gray is one of the famous poems marked as sad poems of the ages. Ode Ode is the formal and long poem serious in nature. Allegory Allegory is the famous form of poetry and is loved by the readers because of its two symbolic meanings.One is the literal meaning and another(prenominal) is the deep meaning. Epic and Mock epic Epics are the narrative poems that convey moral and culture of that period. The Odyssey and Iliad are one of the largest philosophical epics written by Samuel Butler. Rape of the Lock is the great mock epic snap on the minor incident of cutting of a curl. Lyric It has Greek origin that gives a melody of imagery. It is the direct appeal of a poet to the readers about any incident or historical events. Lyrics are most of the time similar to ode or sonnets in the form. Nonfiction LiteratureNonfiction Literature is opposi te to fiction as it is informative and comprises the interesting facts with analysis and illustrations. Main types of Non- fiction literature Autobiography and Biography An story is the story of the authors own life. Family Life at the White House by hooter Clinton is focused on his life and achievements. Wings of fire by Dr. A. P. J. Abdul Kalam, Mein kampf of Adolph Hitler are the autobiography books on real life. Essay Generally the authors point of view about any particular topic in a detailed way is an essay.Essay has simple way of narrating the main subject therefore they are descriptive, lengthy, subject oriented and comparative. Different types of essay Personal essay, expository essay type, response essay, process essay, persuasive essay, argumentative essay, critical essay type, interview essay, reflective essay type, evaluation, observation essay, comparison type of essay, application essay, discriminate and contrast essay and narrative essay type. Literary criticism I t is the critical study of a switch of literature. Here critics apply different theories, evaluation, discussion and explanation to the text or an essay to give total judgments.Plato, Aristotle, T. S. Eliot, Saussure and Frye are some of the famous critics. Travel literature It is the narration of any tour or foreign journey with the description of the events, dates, places, sights and authors views. Francis Bacons natural philosophies in the middle of seventeenth century is one famous example of travel literature. Diary Diaries are the incidents recorded by the author without any means of publishing them. It is the rough work of ones daily routine, happenings, memorable long time or events in their life. E. g.Anne Franks Diary of a Young Girl was published by her father in 1940s its a story of a girl trapped during German invade Amsterdam. Diaries consists of business letters, newsletters, weather listing. In todays world of Internet, writers write in blogs, forums, canvas and s ocial networking sites to convey their thoughts.

Fast Food: Problem in America? Essay

Imagine youre at McDonalds and youre going in for that bite on your burger. First thing you think about is the tastiness of the burger and not exactly what youre eating. Little do you know that youre eating so much stuff that go away actu either(prenominal)y take a toll on your body in the long run? just about Americans do not withstand this thought running through their minds because all they care about is the explosion of flavor in their talk and the satisfaction of being full after. Americans should eliminate the regular consumption of luxuriant provender because the fast intellectual nourishment diet leads to health issues, such as diabetes, corpulency, and boob disease.Diabetes is a common factor after go through fast forages (junk food). For those who do not know what diabetes is Diabetes is a disease in which the body is unable to flop use and store sugar. Sugar backs up in the pedigreestream causing ones blood sugar to rise too high and fast food is high in suga r until now though we do not know it. Even though the fast food may be high in calories, it will lack nutritional value because of the high amount of carbs as good as all the fats. profuse foods are usually high in calories, and highly processed, barely they scarper to have few vitamins and minerals, and are usually low in fiber. Fast foods often contain boastfully(p) amount of added sugar, and high in saturated fats and Trans fats.Besides diabetes, Americans are highly affected from fast foods in the form of obesity. You can find a fast food restaurant every time you turn the corner and you can choose from burgers, tacos or a sugary drink at most places. As mentioned before Fast foods are typically high in calories, fat, sugar, carbohydrates, and sodium. I believe the rate of obesity is so high because of how inexpensive it is to buy and also due to multiple locations of fast food restaurants. corpulency is starting to become a major factor in America these days due to all the fast food we consume.In addition to Obesity in America, it is now becoming a big deal to the youth. As said before, most fast food chains lurk around every corner and isvery tempting to the human eye. Along with the location of fast food our lifestyles have changed oer the years where we live in a fast paced society. The fast food industry understands this which is why there is a drive through window. You can order something healthier on the fast food menu, but most of the time you are being rushed to order and you make the wrong choice, or because the healthier items on the menu are usually the most expensive. Either way this is what I see when I order from fast food restaurants.Finally, the most serious outcome of consuming fast food in your daily will be heart disease and eventually death. Studies found that consuming fast food as little as once a week increases the risk of dying from coronary heart disease by 20 percent. The risk goes up to 50 percent if you eat fast food two to three times weekly, according to the study. Worse still, the risk shoots to 80 percent for those who eat fast food four or more times per week. The study I found was interesting to me and it had me opinion of my own eating habits. Can you imagine with all the excess carbs, fats, sodium, sugars, and cholesterols being absorbed in your dodging that it will play a major role on your cardiovascular system? The thought of this was sooner stunning and should be taught worldwide to prevent heart disease, which will lead to death.Fast food will always be a favorite meal for anyone that doesnt have time to cook, on a budget, or just prefers the tastiness of the grease. Down the road if fast food is consumed daily then the make will be catastrophic on the human body such as diabetes, obesity, and heart disease. Fast food might not seem harmful at first, but the effects will soon become noticeable such as your waist line will become a trade bigger and you will start to feel out of shape even if it is simply walking that you do. Most of this essay is referring to the Americans, but if I were to specify which category that fast food affects the most the category would surmount suit the adults and children would be another category that suits this very well. Childhood obesity is on the rise and everyone end-to-end the world should know this, but for now just be aware that fast food is a major cause for diabetes, obesity, and heart disease.

The Incredible Hulk Review

drawg 10 out of 10 says everyone If not it is because they mustiness be green with envy at the magnum opus that was synthesised by Louis Leterrier himself But still no debate to the first film. Unleash the fury was the tagline for the intellectual production, which is The Incredible Hulk we can certainly say the viewing audience were filled with fury when the film came to an abrupt and odd ending when the wrecked urban center faded outside with no questions answered.The film was far from incredible, I would say unconceivable and that alone wouldnt put a grinning on my face. The film opens with the traditional Marvel trademark guarantying another larger-than-life, adrenaline filled and gleaming translation summoned from Stan Lees genius psyche. We have a glance into the terrible accident that ruined Bruce monetary standards (Edward Norton) life, a brilliant (or terrible? ) experiment involving gamma radiation that renders a monstrous alter-ego that convenes when Bruces anger me ter reaches boiling point.We witness where he has been lowered to a favela in Brazil where the apprehension of being shipped off to a Government facility to be experimented on dominates his every thought. We weigh a little box that reads Days without Incidence 145. His efforts to hide himself from recognition have failed him when a single bedevil of blood oozes from his finger and we get a close up of the betraying blood as it cascades towards the evacuate bottles, Louiss tv camera shot created the effect of a dramatic fall because of the sheer speed at which the blood fell.The Government catch way of the concealed fugitive and the chase is on. The battle begins in the streets of the favela townspeople and the end is inevitable. Yes, the heavyweight does demonstrate his effortless ability to destroy and exterminate things and yes, the Government agents go move.. But after the big brawl that trashed the town and left all Government agents hospitalised Bruce finds himself rando mly in North America and the little box comes up again Days without incidence 0. He ventures to Culver University were the whale was born.He accidentally meets the love of his life, Betty (Liv Tyler) who was dating psychiatrist Leonard Samson (Ty Burrel) who is swiftly aborted when her eyes find themselves pure(a) at Bruce, the connection is rapidly re-established. They seem to fall helplessly in love and their journey starts to taste finding a cure in the hands of Mr Blue In the intervening time a Government soldier named Blonsky (Tim Roth) has been put forward for a test to bestow the precedents of the incredible hulk compound strength, speed, agility, reflexes, endurance and healing. without the defect of massive size and loss of control.He slowly obtains the urge to become more(prenominal) powerful once he saw what the Hulk could do in a brilliant panorama where Bruce had been driven to a glass bridge and gassed shadowing the talented Bruce to renovate into the highly pow erful Hulk, the camera shot A big close up- was effective because it slowly zoomed in to add anticipation to see what was going on in the glass bridge, Bruce is rapidly angered and he metamorphosiss to the hulk then a huge green hand pounds against the glass, the soldiers pupils dilate at the fear inside them. The soldiers tribulation like ants compared with the hulk when he smashing the glass and its integrate with one swoop.They learn that Sterns has developed a possible antidot that may cure Banners condition, or merely reverse each individual transformation. After a successful test, Sterns reveals that he has synthesized Banners blood sample (which he sent from Brazil) into a large supply with the blueprint of using it to bring humans to the next evolutionary level. Appalled by what Sterns had done and fearful of the Hulks power falling into the wrong hands, Banner attempts to convince Sterns to destroy the blood supply, but he is attacked by Ross forces and taken into custod y with Betty.While Sterns is interrogated by a female soldier about his work, Blonsky strikes her down and demands that Sterns inject him with Banners blood sample, as he covets the awesome power of the Hulk. Sterns warns that the combination of the super soldier formula (which Blonsky has overdosed on, slightly deforming his skeleton) and a gamma treatment would be an unpredictable combination that could turn him into an abomination.Unconcerned, Blonsky forces Sterns to administer the gamma charge, and he changes into a hideous monster, with strength and power that surpasses that of the Hulk, but retaining Blonskys intelligence and personality. He knocks Sterns aside and escapes, rampaging through the city to draw the Hulk out. At the lab, an irradiated sample of Banners blood-derivative drips into an open wound on Sterns temple, causing his head to mutate and expand, much to his delight.

Fungi with Focus on Subdivision Zygomycotina and Ascomycotina

Fungi comprises a huge and varied group of organisms that piss common characteristics with both the degrade plants (algae) and lower animals that are not related to each opposite(1, a, b,c). They contain square(a) mitochondria and a membrane-enclosed nucleus. They fork over no chlorophyll and chloroplast. Reproduction is achieved through knowledgeable and asexual promoter(12). Most fungus kingdom grow as branched tubular systems, or mycelia, whose individual filaments or hyphae are surrounded by rigid cadre w solelys containing chitin, cellulose, or both, and other polysaccharides. All fungi lack photosynthetic index and therefore require pre manikined extreme compounds(2).Prior to the development of fungi in the microscope in the 1600s, the only fungi described were the higher fungi that have large fruit structures, such as morels, mushrooms, and puffballs. In 1836, the study of fungi was termed mycology (a branch of botany). The different groups of fungi are branchified according to their means of sexual reproduction, life cycle exhibited, growth and developmental stages, and means of asexual propagation(4). Two Division System Myxomycota and Eumycota. Ainsworth constructed a two-division system for fungithe kingdom is split into two groups, namely Division Myxomycota and Division Eumycota.In Division Myxomycota, the fungi grow as multinucleate amoeboid plasmodia and nurture motile uninucleate amobae, as well as biflagellate cells. The so called true fungi are placed in Division Eumycota. The evolutionary relations for this division whitethorn be described as a atomic minute 53 phyletic series, except for Oomycetes(6). Eumycota and Subdivisions. The Division Eumycota is subdivided into subdivison Mastigomycotina, Basidiomycotina, Deuteromycotina, offshoot Zygomycotina, and Ascomycotina. In subdivision Mastigomycotina, the fungi produce motile spores called zoospores, with one or two flagella.The subdivision Basidiomycotina overwhelms members producing haplontic sexual spores called basidiospores on a specialized cell called the basidium. The subdivision Deuteromycotina includes all fungi that lack know sexual reproductive structures. Most fungi that cannot be sectionalisationified fall under this subdivision. The subdivision Zygomycotina has a single class, Zygomycetes and this class includes fungibread molds or pin moldsthat typically produce an abundant or aerial, coenocytic mycelium and are common causes for the decay of of foods and rich sources of organic material.The subdivision Ascomycotina (formerly the class Ascomycetes) includes all true fungi in which sexual reproduction results in ascospores, produced wi subtle specialized structures called an ascus(7). Zygomycotina. The subdivision Zygomycotina has cell walls containing chitin as a primary component. They reproduce asexually by means of non-motile spores called sporangiospores produced in the sporangia formed on branches (sporangiophores) of the mycelium. In some species, such as the Rhizopus nigrificans, the sporangia arise in clusters with rhizoids at the metrical unit and hyphal strands or stolons interconnecting the clusters.The spores are released by the breakdown of the sporangial wall of the sporangial wall and dispersed by air / track or water current. They germinate by direct outgrowth of hyphal tube to produce a bran-new mycelium. Rhizoids anchor the fungi to the substrate, acting like roots, thus releasing the enzymes necessary to breakdown the substrate and bewitching the broken down nutrients (1). Sexual reproduction may occur between different parts of the mycelium (homothallic mating) or between two sterile strains/cells of opposite mating type. The latter is regulated by a single pair of genes or alleles.One gene is said to be the plus mating type and the other the damaging mating type (8). The gametangia, or the sex organs, fuse to form a dormant, thick-walled pigmented and often sculpted fertilized ovum called t he zygospore. The mature zygospores eventually germinate to produce the new haploid mycelium. The representatives for this subdivision are members of the Rhizopus species like R. oligosporus and R. stolonifer(2). The transmitted regulation of sexual reproduction in fungi was first discovered in Zygomycetes by Albert Blakeslee, who coined the terms homothallism and heterothallism to describe the two opposite mating types.Both are known to be common in throughout the kingdom. Ascomycotina. The subdivision Ascomycotina have chitinous cell walls. In many ascomycetes, male structures (antheridia) and womanish structures (ascogonia) are produced. The antheridia donate nuclei to the ascogonia by fusion with a receptive filament, the trichogyne. In others, the same function may be accomplished by conidia (asexual spores that can also serve as fertilizing elements) or by hyphal fusion. The agnatic nuclei in the ascogonium unite in the ascogonium and enter the hyphal branches that grow out from it within a developing fruiting body called the ascocarp.The paired parental nuclei divide synchronously (conjugate division) in specialized hyphae with binucleate cells (ascogenous hyphae). The tip cells of the ascogenous hyphae form a hook in which the haploid parental nuclei fuse to produce a diploid zygote nucleus. The zygote nucleus immediately undergoes meiotic division to produce four haploid nuclei in the enlarging cell, called the ascus at this type of development. In most cases the a mitotic nuclear division then doubles the number of nuclei per ascus, later on which each nucleus is enclosed in a cell wall to form the ascospores.The hypahe have aboveboard washer-shaped septa with a central pore and the asexual reproduction occurs by formation of non-motile spores conidia, oidia, arthrospores and others that are usually produced on specialized branches called conidiophores. Several classes of ascomycetes exist. The class Hemiascomycetes includes the unicellular o r mycelial yeast. The class Plectomycetes includes several(prenominal) economically important fungi that form their asci in small, simple, closed fruiting structures (cleisthothecia).The powdery mildews are all obligate parasites of higher plants and are largely host-specific. A second major group of plectomycetes include the commercially utilizable genera genus Aspergillus and Penicillium,as well as important pathogens of plants and existence. Sexual reproduction is relatively ancient among species of Aspergillus (185 species) and Penicillium (14 species). Aspergillus produces chains of pigmented, asexual conidia on the surface of an inflated region of a branch called a conidiophore.Conidium formation is similar similar in Penicillium, but the conidiopore is branched to form a brushlike structure (penicillus) instead of having an inflated vesicle. The conidia are connected by chains in conidiophores but are readily dispersed by air currents. The green, black, yellow and gray colo nies of these common microfungi are the results of the ruse of the huge number of pigmented conidia produced on the surface. All fungi in class Pyrenomycetes produce asci and ascospore sas an organize hymenial layer in a fruiting body called perithecium.The perithecium is a small flask-shaped structure with a thin wall that surrounds a basal tuft of asci with the opening at the top called an ostiole. The ascospores are typically dispatch from the tips of the asci as they sequentially protrude from the ostiole. The perithecia may form separate structures on the mycelium, or they may pillow just below the surface of a larger mass of sterile hyphae called stroma(10). In addition to their roles in the decay of plant and animal residues and in food spoilage, these fungi (h,j) are of great significance to humans in many other ways.Aspergillus fumugatus, a common inhabitant of the heated compost, can cause respiratory disease in humans, and a number of related species may produce aflat oxin, a tumor incentive alkaloid, in poorly stored moldy grain(9. ) A. flavus and A. parasiticus produces aflatoxin, B1 (f), B2 (g), G1 and G2, the first mentioned being the most toxic (a, b,c). The disease caused by Aspergillus is termed as aspergillosis characterized by allergy and infection-like symptoms (3,4). The potential threat of Aspergillus as biological branch of mass destruction is still being investigated (d-j).Species of both Penicillium and Aspergillus are used extensively in commercial fermentations. Camembert cheeseflower derives its flavor from Penicillium camemberti, and Roquefort from P. roqueforti. Soy sauce is fermented with Aspergillus oryzae or A. soyae. This class also includes other species that cause disease in humans, animals and plants (4, j) for example the fungus Ceratocystis ulmi is responsible for the Dutch Elm disease, other species cause a wilt disease in oaks and still others reduce the quality in number (3, l). Antibiotics were first fist produce d using penicillin from P.notatum the antibiotic activity of this fungus was first described by Alexander Fleming in 1929. Only through a joint effort of British and American scientists during the World War II, even was the indus streamlet-scale production achieved, by using a better strains of P. chrysogenum. A huge antibiotic industry has since developed. . conglomerate microfungi are used to produced a number of organic acidsgluconic, itaconic and citric acids (d,e, m), for exampleand in other chemical processes. Citric acid fermentation yields about 99,000 each year.Penicilliums uses do not extend to cheese and to antibiotics alone but also in agricultureserves as soil bioinoculant. Ochratoxin is produced by P. viridicatum and P. verrucosum. Selected Bibliography I. Books 1. Ainsworth, G. C. (1976).
