Nicaragua Essays - Nicaragua, Republics, Managua,

Nicaragua Have you ever wanted to go to a place during our winter season that is warm or hot most of the year? Well, most people choose Florida, or California. But, why not go out of the country this winter and try the largest country of Central America, Nicaragua. I did lots of research on Nicaragua, and I hope you learn as much as I did. To begin my report, I will give you some brief history. The first inhabitants of Nicaragua were the Nicaro Indians. This way of life was blended with Spanish settlers when they first came. The name of this tribe was from a great Indian chief, whose name was also Nicaro. This chief was so famous that the country of Nicaragua was also gotten from his name. Next, I will tell you about the land of Nicaragua. It is located in Central America, and is the largest country there. It is on the continent of North America. Nicaragua is 50,193 square miles (130,000 square kilometers). Honduras borders Nicaragua in the north, and it is bordered by Costa Rica on the south. There are two oceans that border Nicaragua. On the east, there is the Carribean Sea and on the west is the Pacific Ocean. Nicaragua has many different types of land forms. There are mostly volcanoes, some active, behind the coastal plains and along the Pacific border. The active volcanoes cause some danger to the coastal cities, but there haven't been any serious accidents. The largest volcano in Nicaragua, the Santiago Volcano, lies south of Nicaragua's capital city. Lots of steam rises from the little holes that surround the volcanoes. East of these volcanic regions are the Central Highlands. This part of Nicaragua is rainy and has some evergreen and deciduous forests dotted around. The forest's floors are flat, not hilly like some other regions. Very few people live in this forest-like place. There are also some lakes in Nicaragua. One lake, Lake Nicaragua, is the largest one in Nicaragua and Central America. The other lake is Lake Managua. Both of the lakes are joined by the Tipatapa River. The Carribean coast is called Mosquito, or Miskito after the small Indian group who lived there. Most Nicaragu ans live there. Although most people live in the Mosquito area, the majority of Nicaraguans say that Matagalpa is the nicest and coolest place to live. Some say that this suburban region is so nice because the sun always shines, but it is less humid than the other Nicaraguan cities and towns. The hottest place in Nicaragua is in the East. It is always hot and wet, but is perfect for growing bananas. There are many rainy places in Nicaragua, and as a result, most of Nicaragua has tropical rainforests. The rainforests are homes to many types of insects and animals. There are many, but I will only name a few. Mammals such as monkeys, alligators, and snakes are the main wildlife. There are billions and billions of (no typing error, just exaggeration) insects from ?A' to ?Z', such as red ants, mosquitoes, and even a striped house fly called the zebra fly! The wild fowl, such as parrots, toucans, macaws, humming birds, and vultures fly through the air. Fur-bearing creatures like the coyote and grey and red fox, roam the evergreen forests and are even sometimes kept as pets. The least likely place you'd find any animals is the small desert area in the west. This is the driest part of Nicaragua. This place even has a dry winter and hot summer season, and the summer season is hotter of the two. As I said before, the most rain falls in the East. The average was about 100-300 inches a year. Almost all the rain that falls to make up the 100-300 average falls in the east. Now I will get away from the land (finally) and tell you some things about the people of Nicaragua. The main ethnic group in Nicaragua is the mixture of European and Indian decent, or Mestizoes. 5% are of American Indian decent, and 17% are European. 99% of the population's skin color is black. The main religion was Christianity, beginning in the early 1500's when the Spanish missionaries

All friends shall Taste the Wages of their Virtues, and all Foes the Cup of their Deserving Essay Example

All friends shall Taste the Wages of their Virtues, and all Foes the Cup of their Deserving Essay Example All friends shall Taste the Wages of their Virtues, and all Foes the Cup of their Deserving Essay All friends shall Taste the Wages of their Virtues, and all Foes the Cup of their Deserving Essay Essay Topic: Literature Throughout King Lear, characters judge and put each other on trial. Gloucester and Lear both misjudge their children, who seem to possess better judgement. Cordelia has the measure of her sisters and Goneril and Regans assessment of their father is acute and accurate. They see how full of changes his age is and Edmund knows exactly how to take in his gullible relatives, whom he despises for being overlooked, due to his being conceived in the lusty stealth of nature and his bastardy status. It seems that good judgement is not the preserve of those with good intentions. The working of human justice reflects Lear and Gloucesters faults. The trials that occur in the play are all flawed. Lears love-test is ill conceived and has disastrous consequences. Goneril may claim to love [Lear] more than word can wield the matter beyond what can be valued, rich or rare and Regan does proclaim to be of that self mettle as [her] sisterAndalone [she does] felicitate in [his] dear highness love. Yet it is Cordelia, Lears youngest, who says nothing, that does truly love her lord. In Act 2, the trial of Kent for plain speaking is an excuse for Cornwall and Reagan to exercise power in an arrogant way. Lears mock trial of Goneril and Regan is presided over by a lunatic and attended by a fake madman and a court jester, his all-licensed fool, his boy. The trial is a parody of the love-test in act one scene 1. It highlights the absurdity of Lears actions in the aforementioned scene, where Lear is mad. It also undermines all other trials carried out by authority figures in King Lear. Gloucesters blinding is an appalling example of human injustice, it is not he who deserves such a misfortune, he has sent the lunatic Kingto Dover, which in his mind is still serving his old King and is thus not treacherous. Cornwall and Regan pervert the law to satisfy their own craving for revenge. It is possible to see the battle between the French and the English forces as another trial, which has dire consequences. Cordelia is hanged in prison and Lear dies. Some see Cordelias death as the greatest injustice in the play. Human judgement and the justice system look extremely fallible when the curtain goes down on act 5. This point is reinforced by the examples of natural or poetic justice that we see in the play. In act 5 scene 3, Edgar takes the law into his own hands when he challenges Edmund. This is wild justice at work. However, as the reader, we accept the outcome of the duel as appropriate. Edmund deserves to die; Edgar states, if [his] speech offend a noble heart, thy arm may do thee justice. We see poetic justice at work elsewhere; Cornwall is turned on and killed by his own servant, Goneril and Regan are destroyed by their jealous lust, Regan has a full-flowing stomach, and Oswald meats a sticky end when Edgar hast slain him, yet once dead, the ever loyal servant of Goneril, Oswald, will not be missed by anyone, he is but an extension of his Mistress, who is herself is a hideous person. The thorniest question about justice concerns Gloucester and Lear. The necessity for their death, it can be said, is questionable. Some may say that a rather harsh kind of justice is at work here. Edgar suggests this when he says to Edmund the dark and vicious place where thee he got cost him his eyes. Gloucester pays very dearly for his sins (although some Elizabethans believed that blinding was the appropriate punishment for adultery). Lear also pays for his sins, Cordelia is taken from him immediately after he recognises her merits, this is too much for the already maddened King, his poor fool is hanged meaning his daughter, as it was a term of endearment. Yet this term indeed remembers Lears other favourite, his Fool. This double reference leads us to believe that Lear has lost his two dearest. We can now ask, is this not justice enough? Lear has now lost all that originally was dear to him, and all that he was taught was dear to him during his moments of madness. Although his judgement has been restores, it is too late for the monarch Lear. King Lear is also concerned with social justice. Lear and Gloucester both consider this topic carefully and seem to reach radical conclusions. Gloucester calls upon the heavens to distribute wealth more evenly; while Lear considers the lives of poor naked wretches he paid so little attention to. In Act 4, Lear rages against corrupt members of the judiciary and seems to sneer at himself when he says a dogs obeyed in office. At the end of the play we are presented with two new agents of justice, Albany, and Edgar. We accept the justice of their actions in Act 5 Scene 3. But human judgement still looks faulty. Albany has been overwhelmed by events and Edgars bitter words about Gloucesters death seem callous. Surely nobody in King Lear is morally impeccable? Perhaps Shakespeare wants us to remain uncomfortable about justice.

Economic Background of Tesco Case Study Example | Topics and Well Written Essays - 1500 words

Economic Background of Tesco - Case Study Example As a group its turnover is 28 billion per year and even as a leader it continues to build market share because of its winning strategy.( Corporate Watch, 2004). In this paper we aim to get an insight into Tesco's economic strategy and analyse the different problems it currently faces and might encounter in the future. We also aim to present plausible solutions to tackle the stated problems. Tesco has an insatiable appetite for space, and relentlessly pursues the best new sites. When it comes to just number of stores and locations, Tesco leaves its rivals standing. In the 1960s, Tesco was buying up literally hundreds of grocery stores and small grocery chains around the country. It introduced 'Home 'n' Wear' departments into larger stores to carry higher-margin non-food merchandise, including clothing and household items, and opened its first 40,000ft 'superstore' in Crawley, Sussex. In 2002, it stunned experts and the competition by buying T&S, a chain of 850 convenience stores across the country. The deal doubled the group's store count in the UK at a stroke. The scale of it allowed them to capture quite an increase in market share, and they really caught the rest of the industry off guard. Learning from its past mistakes, Tesco diversified its level of products and prices to appeal to all income brackets in the same store. Tesco offers three distinct ranges of own-brand products, from Value to Finest, priced to attract all types of shoppers to its stores. Therefore in spite of its humble beginnings as a 'thrifty' store, Tesco now has more upmarket customers than M&S and Waitrose put together attracting 15 million customers per week to its stores comprising of the high and low income customer segments. Investing in Growth, Diversification and Expansion-Thinking Big: Tesco has multiplied its power and standing by reaching far and wide both in terms of diversification and expansion in terms of products and locations. It has expanded its grocery retailing at home in UK by finding innovative and energetic in finding ways to expand, such as making a large-scale move into the convenience-store sector, which the major supermarket chains have traditionally shunned. Tesco has found stunning success in its diversification to non-food business. In 1974, in a deal with Esso, Tesco began to open petrol stations on the grounds of its superstores. The idea was successful and by 1991 Tesco was the country's largest independent petrol retailer: it now accounts for 12.5% of all petrol sold in the UK. (Corporate Watch,2004).By late 2004 it was widely regarded as a major competitive threat to traditional high street chains in many sectors, from clothing to consumer electronics to health and beauty to media products. Tesco sells an expanding range of own-brand non- food products, including non-food Value and Finest ranges. Tesco has pioneered the concept of retail services. Tesco has taken the lead in its sector in

The Analysis of the Niagra Movement Essay Example for Free

The Analysis of the Niagra Movement Essay After reconstruction African American were still trying to recover from the inequality and the lack of education in the southern states. The nadir period was the time were African Americans aimed at eliminating racial discrimination, equal job opportunities, and improving their political power. The thirteenth, fourteenth, and fifteenth amendment, reconstruction, plessy vs. Ferguson, and radical republicans were all factors that helped black folks advance in society. Booker T.Washington and W.E.B Dubois were to powerful civil rights activist who had two different views on the status of African Americans. The Declaration of Principles of the Niagara movement and Booker T.Washington’s Atlanta Exposition address that were two documents which explained the views of African Americans in the states. This paper will argue that the Atlanta exposition Address was a way to keep peace between the white and black race and that the Niagara Movement was a prime example of principles blacks work so hard to achieve. In the Atlanta Exposition Address Booker T Washington stated that African Americans should deal with accommodation and work on their industrial education. Also he stated that black folks should work and submit to white political power and eventually you will receive a basic education in a moment of time .He also proved us with a fact that states â€Å"We have proven our loyalty to you in the past† .This statement basically explains how African Americans were trusted to take care of the elderly and children .Africans took care of whites from birth to death .Sitting by a elder beside when death has struck. The loyalty of blacks should never be factors because they have been loyal for decade’s .Booker also argue that during reconstruction the advancement of blacks struck way to fast. You can’t expect to get the things you want immadiately you have to start from the bottom to get to the top .Meaning if you adjust to industrial education then you can receive basic edu cation. It is important to stay humble, loyal, and to contribute to the south industries stated Washington. In the Declaration of Niagara Movement the idea of the African American race to have equal education, political power, brotherhood and no racial discrimination was the main ideas .W.E.B Dubois stated that the black race should not submit to inequality and should protest for equal rights. Suffrage economic opportunity ,Civil liberty duties and education are all issues African Americans wanted and felt they had worked so hard and fought in wars for .Dubois states that to be racial prejudice hurts brotherhood and to segregate black men is unchristian and disgraceful. The bible talks about how you should be kind to your neighbor and be kind to others. When white folks so called they Christians the way they treated blacks was unchristian like and it made them question their relationship with god. Booker T .Washington wrote the Atlanta Exposition Address to explain industrial education as a representative of the Negro race during the nadir period. He approaches the southern whites as someone who wants a friendship between the two races .In the address Booker gave a great description of industrial education in relations to African Americans. When he uses the term us he is referring to the white and black race as a whole. When using me he refers to his own race .W.E.B Dubois Declaration of Principles was addressed to the members of the conference known as the Niagara Movement, Which assembled in an annual meeting in buffalo New York. His declaration was to end racial discrimination and to crown brotherhood .It was important for Dubois to let his people understand that accommodation and racial segregation was not something they were going to settle for .How can you fight for your countries when you don’t have rights in the states. After reconstruction ended African Americans went back to being segregated all that they had worked so hard for was gone .They lost political power, segregation was enforced, and a wide spread of violence on the black race had occurred .After Andrew Johnson was impeached radical republicans took over .At this time African Americans believed that since they didn’t get what they wanted immadiately they should work on themselves and accept inequality in hopes of a better future. Accommodation was a tragedy used to explain how industrial education was a good way to help blacks grow as a race. During the industrial education the philposher Booker T.Washingtion helped establish Tuskegee University which helped black learn how people how to be barbers, nurses, cooks, hair stylist etc jobs white folks didn’t want. The Atlanta Exposition Address was a state of address to show the struggle of the race and how blacks are willing adjust to industrial education in hopes of basic education. Even thou a lot of African Americans believed in accommodation it was some felt that accommodation it was some who felt that they deserve rights and quality immediately .The Niagara movement believed in protest and thought inequality was unconstitutional .The Movement believed that the economic life was a big social issues and affect most lower class families . Not having job avaliblites forced blacks to move up north .As blacks wanted to adjust and move in political powers they still faced segregation and unfair jobs. People of the Niagara movement believed that the United States should aid common school education. That trade school only to keep you in the slavery mind set. Having pride in your nation that all men were created equal and free but still blacks fought in war field and still got hunged by southern states soldiers. It made African Americans feel as if they were still being treated as a second-class citizen and no rights. The Declaration of Pringles was a document that declared to white folks that blacks were tired of inequality and boycotting riots were their only option left. The Atlanta Exposition Address and The Declaration Of prinples of the Niagara movement where two documents written by to civil rights activist who had two different views of African Americans fate in the states.Accomodation an d boycotting were two stragies presented in the documents. It is important that whites understand that equal rights,education,and jobs were things blacks had the desire to want and was going to gain eventually .This paper argues that the Address document was just a way to keep peace between two races. You can’t keep peace if one race is adjusting to the other .This document argued a good point that you have to start from the bottom to get to the top. During the reconstruction black folks were put in political office and congress .African Americans advanced really quickly in a few years and it was a lot to take in .A Booker T. Washington tragedy was logical but didn’t help blacks with their education, jobs, and civil rights. However the prinples of the Niagara was well written prime example of black people wanted .In the document education ,jobs, freedom ,and civil liberty were discussed and well discussed in the way African Americans wanted .During the nadir period African American were tired of inequality and felts as if they should have a basic education and quality like blacks. This document was a basic outline of what African Americans wanted and how they were no longer accepting inequality.

Compare and Contrast Death of a Naturalist, An Advancement of Learning

Compare and Contrast Death of a Naturalist, An Advancement of Learning and The Early Purges. In this essay I am going to discuss ‘Death of a Naturalist’, ‘An Advancement of Learning’ and ‘The Early Purges’ by Seamus Heaney. I will focus on the similarities and differences between these poems in terms of what they are about, their language and themes. The first out of the three poems by Heaney that I have studied is ‘Death of a Naturalist’. This poem is about Heaney as a young child, exploring a field. He comes across frogspawn and remembers when his teacher would tell him about how the â€Å"Daddy frog was called a bull frog†, â€Å"and how the mammy frog laid hundreds of little eggs and this was frogspawn†. Heaney then writes about when he used to steal the frog spawn and put it into a jam jar for school, and how he would watch them grow into tadpoles. When he finishes describing what he did, Heaney starts a new stanza. The mood changes in stanza in this stanza. Heaney describes the frogs as angry, and that they were croaking in a way he had never heard; â€Å"The air was thick with a bass chorus.† Heaney claims in the poem, that the frogs were angry at him for stealing the frogspawn when he was younger. Heaney â€Å"sickened, turned and ran.† The second poem entitled â€Å"An Advancement of Learning†. This poem is about Heaney taking a walk along an embankment and coming across a rat that was crawling out of the river. Heaney writes â€Å"I turned down the path in cold sweat†. However he comes across another rat. Heaney claims that the rat was staring at him, â€Å"insidiously listening†. He describes the rat having â€Å"raindrop† eyes. Heaney stares back at the rat – â€Å"forgetting how he used to panic† when he lived on a farm. The rat â€Å"... ... In conclusion, the main similarities between the three poems are in the language used. By this I mean that of particular phrases such as war words and the usage of similes and alliteration and the fact that they are all about animals and fear. The main differences are that â€Å"The Early Purges† is a different structure to the other two poems. I have learnt about parts of Seamus Heaney’s childhood and his coping with fear. I have also learnt different techniques to use in poems, for example alliteration. I have enjoyed the excitement Heaney builds up in each poem. My favourite poem is â€Å"An Advancement of Learning† because I can understand and picture everything Heaney describes. Also it is my most preferred poem due to the fact I can relate to confronting a fear and not having a path to turn to and then the fear swam away from me, so I can relate to the story.

Complexometric Determination of Water Hardness

Complexometric Determination of Water Hardness Abstract: Create a standardized EDTA solution for use as a titration solution to determine the hardness of water from a single random sample. Introduction: Using a calibrated EDTA solution to determine water hardness from a random sample. Essentially the Na2EDTA solution reacts one to one with the mineral content of a sample of tap water and by use of a standardized solution a ppm estimation can be obtained for the hardness of water.Current knowledge in this area is well understood and procedures used follow generally accepted guidelines. Method: First the calibration was completed using an approximately . 7340g Na2EDTA/500mL solution. A 1. 000g/L calcium ion solution was used as the primary standard with approximately 3mL of ammonium chloride as a buffer and Erichrome Black T as the indicator solution. Three titrations were performed to ensure accuracy of the molarity of the Na2EDTA solution. The 1. 000g/L calcium ion solution had to be converted to M so 1g/L/100. g=. 009990M calcium ion solution. Titration 1: 10. 00mL CaCO3; . 00999MCaCO3X. 0100L= . 0000999mol CaCO3 . 0000999mol EDTA/. 002507L = . 00398M Na2EDTA Titration 2: 10. 00mL CaCO3; . 00999MCaCO3X. 0100L= . 0000999mol CaCO3 . 0000999mol EDTA/. 02339L = . 004271M Na2EDTA Titration 3: 9. 95mL CaCO3; . 00999MCaCO3X. 0100L= . 0000994mol CaCO3 . 0000994mol EDTA/. 02367L = . 004196M Na2EDTA Since the first titration is so far out from the other two it was thrown out giving an average result of . 04233M Na2EDTA Sample B was used in this experiment with at 25mL and three titrations were performed to ensure accuracy with the same buffer solution (appx 3mL ammonium chloride @ pH10). A magnetic stirrer and standard burette were used in the procedure with a read accuracy to . 01mL. Eriochrome Black T was the indicator solution. Results: Titration 1: 12. 52mL Na2EDTA; . 00423M Na2EDTA x . 01252L = . 0000530 mol . 0000530mol/. 02496L = . 00212M hardness Titration 2: 12 . 19mL Na2EDTA; . 00423M Na2EDTA x . 01219L = . 0000516 mol . 0000516mol/. 2499L = . 00206M hardness Titration 1: 12. 23mL Na2EDTA; . 00423M Na2EDTA x . 01223L = . 0000517 mol .0000517mol/. 02505L = . 00206M hardness (. 00212M+. 00206M+. 00206M)/3 = . 00208M Discussion: The results are very consistent however the website for checking the data is no longer valid. Provided that the titration solution was calibrated properly the results from the experiment to determine the hardness of water should be accurate with a margin of consistency between samples vs. average hardness @ 1. 89% at most for any of the three samples.

Research Investigation: commedia dell’arte masks Essay

According to italian theatre historians, such as Roberto Tessari, Ferdinando Taviani, and Luciano Pinto, Commedia dell’arte, which literally translated as improvised comedy, developed as a response to the political and economic crisis of the 16th century in Italy and, as a consequence, became the first entirely professional form of theatre [1]. It is believed that the use of mask in commedia dell’atre originated in 1570 with Andrea Calmo, the actor and author who was inspired by the venetian carnivals of the time. She created Pantaloon who is the one of the most famous characters of commedia dell’arte today. She went on to create the spanish captain ‘Il Capitano’. Although her characters were initially unmasked, Andrea wished that the spirit of the Italian carnival ( which celebrates the epiphany [2] ) would be represented in her plays and therefore she introduced the masks and thus created the commedia dell’arte that we know today. [3] The carnival of venice. [1] Records of commedia dell’arte performances date back as early as 1551, where they were acted by professionals outside on temporary stages with costumes and masks. But as it was so popular with the nobles, many performances were also done indoors at court for the amusement of nobles. [4] After it became famous with the nobles the troupes began to move to france where many play writes such as Moliere were inspired to move their written works towards comedy.[5] Commedia dell’arte started to become popular outside Italy in the beginning of the seventeenth century. As the ‘tipo fisso’ (fixed stereotypes) soon became satiric references to the Italian parliament and to the typical Italian person it became one of the most popular comic theatre genres in the 17th and 18th century. [6] There are several reasons for the use of masks in commedia dell’atre. Primarily, as this type of theatre has fixed characters but is essentially improvised, the masks are used so that the audience was able to identify the characters. As commedia dell’arte was performed by different travelling companies, this meant that they would have different costumes, yet the masks would retain all the information needed to recognise a specific character. [7] Also as these performances were mainly on the streets or by the road, there would not really be a stage nor seating for the audience this made it difficult for everyone to see everything from the same angle or height. With the masks, all the audience could observe the emotions or actions that were being portrayed.[8] Commedia dell’arte masks were traditionally made of leather and only covered half of the actor’s face. They were like this so that the actor was able to project his voice and made certain noises that he could not do with a full mask. The masks were made to fit the face of a given actor because he or she would generally act out the same character for his/her entire career. Commedia dell’arte masks tend to have large, broad feature which are distinct to each character. For example on the character Zanni, the nose is very large. It is said that the larger the nose is, the stupider the Zanni represented tends to be. Zanni [2] Zanni [3] As I have said before, commedia dell’arte characters were based on ‘tipo fisso’ (a certain stereotype). Some of them have changed there name or personality over time for example Zanni, who is characterised as short of wit and always without money. Zanni has several masks that represent him which have changed over time with the fashion. Which all mean different things for example the Brighella mask which represents that poor and starving and hopeless side of Zanni and the Pucinella mask which represents the side which is also poor but although he is stupid he is able to outwit many. Many of the characters had a stereotypical opposite for example the stereotypical opposite of Zanni is represented with the well known character Pantalone (Pantaloon) who is typically arrogant and rich and who is always dealing with people who are trying to take his money away from him. Pantalone [4] Although most of the commedia dell’arte characters wore masks, there were few that were never masked. For example Isabella. Who was most famously acted by the famous actress Isabella Andreini. Also the lovers who were mostly the daughters and sons of the old and rich such as Pantalone or The Captain did not wear masks. This is because they were just there to bring the satiric comedy of romance and love to the performance. They were there to make the performance more light. And therefore did not have a specific characteristic apart from being completely in love with their character. [10] Commedia dell’arte masks were useful in the sense that although the the costumes and stage changed in fashion over time, The masks stayed basically the same. In this way the audience could appreciate and recognise the character and still enjoy new ways of the typical story being presented. In many schools such as Jaques Lecoq’s international school of theatre in paris, commedia dell’arte masks are used as a learning instrument for aspiring actors. Jaques Lecoq, was born in 1921 started off as a sports teacher and then moved on to acting with his partner, Gabreielle Cousin. He moved to Italy for eight years in 1948 where he discovered Commedia dell’arte. Together with the sculptor, Amleto Sartori, they developed the neutral mask. When Lecoq moved back to Paris he devoted the remainder of his life to teaching at his school. Jaques Lecoq [5] His school offers several courses that work on understanding and working with the body through the use of masks. His philosophy was that in order to become a good actor, you needed to use the Neutral masks to discover your body, movement, balance and space. He also believed that the typical half masks of commedia dell’arte, played an important role in improvisation and to work on character types therefore he integrated both into his courses [11].

10 Fascinating Facts About Fireflies and Lightning Bugs

10 Fascinating Facts About Fireflies and Lightning Bugs Fireflies or lightning bugs are from the family Coleoptera:Lampyridae, and they may well be our most beloved insect, inspiring poets and scientists alike.  Most importantly to remember, fireflies are neither flies nor bugs. Fireflies are actually beetles and there are 2,000 species on our planet. Here are other interesting facts about fireflies. The Flight of Fireflies Like all other beetles, lightning bugs have hardened forewings called elytra, which meet in a straight line down the back when at rest. In flight, fireflies hold the elytra out for balance, and rely on their membranous hindwings for movement. These traits place fireflies squarely in the order Coleoptera. Fireflies Are the Worlds Most Efficient Light Producers An incandescent light bulb gives off 90 percent of its energy as heat and only 10 percent as light, which is something you know if youve ever touched one thats been turned on for a while. If fireflies produced that much heat when they lit up, they would incinerate themselves. Fireflies produce light through an efficient chemical reaction called chemiluminescence that allows them to glow without wasting heat energy. For fireflies, 100 percent of the energy goes into making light; and accomplishing that flashing increases the firefly metabolic rates an astonishingly low 37 percent above resting values. Fireflies are bioluminescent, which means they are living creatures that can produce light. That trait is shared with only a handful of other terrestrial insects, such as click beetles and railroad worms. The light is used to attract prey and members of the opposite sex, and warn off predators. Lightning bugs taste bad to birds and other potential predators, so the warning signal is a memorable one to those that have sampled before. Fireflies Talk to Each Other Using Light Signals Fireflies dont put on those spectacular summer displays just to entertain us. Youre actually eavesdropping on the firefly singles bar. Male fireflies cruising for mates flash a species-specific pattern to announce their availability to receptive females. An interested female will reply, helping the male locate her where shes perched, often on low vegetation. Fireflies Are Bioluminescent Throughout Their Life Cycles We dont often see fireflies before they reach adulthood, so you may not know that fireflies glow in all life stages. Bioluminescence begins with the egg and is present throughout the entire lifecycle. In fact, all firefly eggs, larvae, and pupae known to science are capable of producing light. Some firefly eggs emit a faint glow when disturbed. The flashing part of fireflies is called a lantern, and the flashing is controlled by the firefly using neural stimulation and nitric oxide. The males often synchronize their flashes with one another during courtship, a capacity called entraining (responding to an external rhythm) once thought only possible in humans, but now recognized in several animals. Colors of firefly lights range widely among different species, from yellow-green to orange to turquoise to a bright poppy red. Fireflies Spend Most Their Lives As Larva The firefly begins life as a bioluminescent spherical egg. At the end of the summer, adult females lay about 100 eggs in soil or near the soil surface. The worm-like larva hatches out in three to four weeks and throughout the fall hunts prey using a hypodermic-like injection strategy similar to bees. Larvae spend the winter below ground in several types of earthen chambers. Some species spend more than two winters before pupating, in late spring, and they emerge as adults from their pupa after a period of 10 days to several weeks. Adult fireflies live only another two months, spending the summer mating and performing for us before laying eggs and dying. Not All Adult Fireflies Flash Fireflies are known for their blinking light signals, but not all fireflies flash. Some adult fireflies, most notably those that inhabit the western areas of North America, dont use light signals to communicate. Many people falsely believe that fireflies dont exist west of the Rockies since flashing populations are rarely seen there...but they do. Firefly Larvae Feed on Snails Firefly larvae are carnivorous predators, and their favorite food is escargot. Most firefly species inhabit moist, terrestrial environments, where they feed on snails or worms in the soil. But a few Asian species use gills to breathe underwater, where they eat aquatic snails or other mollusks. Some species are arboreal, and their larvae hunt tree snails. Some Fireflies Are Cannibals We dont know much about what adult fireflies eat. Most dont seem to feed at all, while some are believed to eat mites or pollen. We do know what Photuris fireflies eat, though- other fireflies. Photuris females enjoy munching on males of other genera. These well-known Photuris femme fatales use a trick called aggressive mimicry to make meals of other fireflies. When a male firefly of another genus flashes its light signal, the female Photuris firefly replies with the males flash pattern, suggesting she is a receptive mate of his own species. She continues luring him in, closer and closer, until hes within her reach. Then her meal begins. Adult female Photuris fireflies are also kleptoparasitic and can be seen feeding on a silk-wrapped Photinus species firefly (occasionally even one of its own kind) hanging in a spiders web. Epic battles can occur between the spider and the firefly. Sometimes the firefly can hold off the spider long enough to consume the silk-wrapped prey, sometimes the spider cuts the web and her losses, sometimes the spider catches the firefly and the prey and gets them both wrapped up in silk. Firefly Luciferase Is Used in Medical Research Scientists have developed remarkable uses for firefly luciferase in the research lab. Luciferase is the enzyme that produces bioluminescence in fireflies. It has been used as markers to detect blood clots, to tag tuberculosis virus cells, and to monitor hydrogen peroxide levels in living organisms; hydrogen peroxide is believed to play a role in the progression of some diseases, like cancer and diabetes. Fortunately, scientists can now use a synthetic form of luciferase for most research, so the commercial harvest of fireflies has decreased. Firefly populations are decreasing, and the search for luciferase is just one of the reasons. Climate change and modern construction have resulted in the loss of firefly habitats, and light pollution depresses the ability for fireflies to find mates and reproduce. Some Fireflies Synchronize Their Flash Signals Imagine thousands of fireflies lighting up at precisely the same time, over and over, from dusk to dark. This simultaneous bioluminescence, as it is called by scientists, occurs in just two places in the world: Southeast Asia and Great Smoky Mountains National Park, right here in the U.S. North Americas lone synchronous species, Photinus carolinus, puts on its light show in late spring each year. The most spectacular show is said to be the mass synchronous display of several Pteroptyx species in Southeast Asia. Masses of male fireflies congregate in groups (called leks) and in unison emit rhythmic courtship flashes. One hotspot for ecotourism is the Selangor River in Malaysia. Lek collective courting happens occasionally in American fireflies, but not for long periods. In the American Southeast, male members of the blue ghost firefly (Phausis reticulate) glow steadily as they fly slowly over the forest floor searching for females from about 40 minutes after sunset until midnight. Both sexes emit a long-lasting, nearly continuous glow in the forested regions of Appalachia. Annual tours to see the blue ghosts can be joined at state forests in South and North Carolina between April and July. Sources Buschman, Lawrent L.

An Explanation of Buffering in C++

An Explanation of Buffering in C++ Buffer is a generic term  that refers to a block of computer memory that serves as a temporary placeholder. You might encounter the term in your computer, which uses RAM as a buffer, or in video streaming where a section of the movie you are streaming downloads to your device to stay ahead of your viewing. Computer programmers use buffers as well. Data Buffers in Programming In computer programming, data can be placed  in a software buffer before it is processed. Because writing data to a buffer is much faster than a direct operation, using a buffer while programming in C and C makes a lot of sense and speeds up the calculation process. Buffers come in handy when a difference exists between the rate data is received and the rate it is processed.   Buffer vs. Cache A buffer is temporary storage of data that is on its way to other media or storage of data that can be modified non-sequentially before it is read sequentially. It attempts to reduce the difference between input speed and output speed. A cache also acts as a buffer, but it stores  data that  is expected to be read several times to reduce the need to access slower storage.   How to Create a Buffer in C++ Usually, when you open a file, a buffer is created. When you close the file, the buffer is flushed. When working in C, you can create a buffer by allocating  memory in this manner: char* buffer new char[length]; When you want to free up the memory allocated to a buffer, you do so like this: delete[ ] buffer; Note: If your system is low on memory, the benefits of buffering suffer. At this point, you have to find a balance between the size of a buffer and the available memory of your computer.

Design of Heat Transfer for a Chemical Reactor Assignment

Design of Heat Transfer for a Chemical Reactor - Assignment Example The instrumentation part includes putting in place the correct system such as closed loop control system, sensors and pneumatic valves for control of flow rate and temperatures. Much appreciation goes out to all the persons responsible in several ways for the success of this research, mostly to those who have made me gain much more than what the scholastic aspects of the course could have accorded. Much gratitude also goes to my lecturer for the basic knowledge he has provided in class. Production of Acrylic acid starts with propylene being partially oxidized in a fluidized -bed reactor. Propylene is broken down to acrolein in the process of getting catalytic gas at an oxidation stage. This takes place in presence of oxygen gas. The fluidized-bed reactor includes a packed-bed with a stirred tank that creates continuous flow reactors. It must posses some good characteristics of both heat and mass transfers. Substrates moves upwards through the bed which is immobilized with enzyme at high velocity which moves the particles up leading to though mixing. The reactor is normally used in highly exothermic reactions because it clears local hot-spots simply because of the mass and heat characteristics the fluidized -bed reactor has. The substrates are normally catalytic material where chemical reactants are given support. After achieving some optimum speed the reactor gets into a stage where the force of the fluid in the solids becomes enough to make a balance between the fluid and the solid materials. The contents of the bed-reactor begin to expand and swirl about in a manner equivalent to a agitated tank or a boiling pot of water after passing this level. This is where the reactor becomes a fluidized bed (Coulson, Richardson & Sinnott,1993). Pressure and temperature conditions in the process changes regarding the mode of reaction going on. Putting the fluidized-bed reactor in the higher section with higher temperatures and pressure than other areas provides good results since it promotes the needed reaction. The vapor velocity influences the rate of circulation for the catalyst. The velocity for the catalyst in inversely
