Patrick Henry essays
Patrick Henry essays Patrick Henry was a lawyer patriot, orator and was a symbol for the the American fight for liberty and self government. Patrick Henry was born in 1736 in Hanover County, Virginia 1736 and died in 1799. He was educated in a country school and in a school kept by his father. Henry tried merchandising and farming, but lost money at both. He then turned his mind to the study of law, and was admitted to practice in 1760. Three years later he won reputation by the management of a famous law case, known as the Parson's Cause. At that day the clergymen of Virginia, like those of England, were entitled to salaries from public funds. Their salaries were given in part in the currency of the day, namely tobacco. In 1764 he moved to Louisa county, Virginia, where, as a lawyer, he argued in defense of broad voting rights before the House of Burgesses. The following year he was elected to the House and soon became its leading radical member. He instilled the point that a king who vetoed a good and helpful law made by a locally elected representative body was not a leader to his people. Patrick Henry had been called a traitor who committed treason in his struggle against the Stamp Act. In 1774 he represented Virginia in the First Continental Congress where he continued in the role of firecracker. At the start of the revolution, he returned to his native state and lead militia in defense of V irginia's gunpowder store, when the royal Governor spirited it aboard a British ship. Henry forced the Governor Lord Dunmore to pay for the power at fair price. In March 1775 Patrick Henry told colonists to arm themselves in the war against England, speaking the immortal words: I know not what course others may take; but as for me, give me liberty or give me death Henry's call to arms was returned with a warrant on his head placed by the King of England. Henry responded with the remark a Quaker in religion but ...

How to Name Ionic Compounds
How to Name Ionic Compounds Ionic compounds consist of cations (positive ions) and anions (negative ions). Ionic compound nomenclature or namingà is based on the names of the component ions. In all cases, ionic compound naming gives the positively charged cation first, followed by the negatively charged anion. Here are the principal naming conventions for ionic compounds, along with examples to show how they are used: Roman Numerals in Ionic Compound Names A Roman numeral in parentheses, followed by the name of the element, is used for elements that can form more than one positive ion. There is no space between the element name and the parenthesis. This notation is usually seen with metals since they commonly display more than one oxidation state or valence. You can use a chart to see the possible valences for the elements. Fe2 Iron(II)Fe3 Iron(III)Cu Copper(I)Cu2 Copper(II) Example: Fe2O3 is iron(III) oxide. Naming Ionic Compounds Usingà -ous and -ic Although Roman numerals are used to denote the ionic charge of cations, it is still common to see and use the endings -ous or -ic. These endings are added to the Latin name of the element (e.g., stannous/stannic for tin) to represent the ions with lesser or greater charge, respectively. The Roman numeral naming convention has wider appeal because many ions have more than two valences. Fe2 FerrousFe3 FerricCu CuprousCu2 Cupric Example: FeCl3 is ferric chloride or iron(III) chloride. Naming Ionic Compounds Usingà -ide The -ide ending is added to the name of a monoatomic ion of an element. H- HydrideF- FluorideO2- OxideS2- SulfideN3- NitrideP3- Phosphide Example: Cu3P is copper phosphide or copper(I) phosphide. Naming Ionic Compounds Usingà -ite and -ate Some polyatomic anions contain oxygen. These anions are called oxyanions. When an element forms two oxyanions, the one with less oxygen is given a name ending in -ite and the one with more oxygen are given a name that ends in -ate. NO2- NitriteNO3- NitrateSO32- SulfiteSO42- Sulfate Example: KNO2 is potassium nitrite, while KNO3 is potassium nitrate. Naming Ionic Compounds Using hypo- and per- In the case where there is a series of four oxyanions, the hypo- and per- prefixes are used in conjunction with the -ite and -ate suffixes. The hypo- and per- prefixes indicate less oxygen and more oxygen, respectively. ClO- HypochloriteClO2- ChloriteClO3- ChlorateClO4- Perchlorate Example: The bleaching agent sodium hypochlorite is NaClO. It is also sometimes called the sodium salt of hypochlorous acid. Ionic Compounds Containing bi- and di- Hydrogen Polyatomic anions sometimes gain one or more H ions to form anions of a lower charge. These ions are named by adding the word hydrogen or dihydrogen in front of the name of the anion. It is still common to see and use the older naming convention in which the prefix bi- is used to indicate the addition of a single hydrogen ion. HCO3- Hydrogen carbonate or bicarbonateHSO4- Hydrogen sulfate or bisulfateH2PO4- Dihydrogen phosphate Example: The classic example is the chemical name for water, H2O, which is dihydrogen monoxide or dihydrogen oxide. Dihydrogen dioxide, H2O2, is more commonly called hydrogen dioxide or hydrogen peroxide.

Strategic Management Essay Example | Topics and Well Written Essays - 1000 words - 6
Strategic Management - Essay Example Primark has been a retailing giant in the fashion industry that has over a few years been successful. Some of its strategies have over the years included effective marketing to specific targets across Europe. Primarkââ¬â¢s target market is mostly the fashion sensitive age group which is basically people with the age below thirty five years of age. They also deal mostly with brand names that are minor, which translates to cheap quality fashionable trends. They have maintained their market by providing the same product of the same quality at a lower price than their competitor provide. This accompanied with the effective management of response and delivery mechanisms has ensured that Primark has maintained its competitive and reliability position in the European market. Their computerised warehouse controls and an effective efficient distribution networks has made sure that Primark stays top notch in customer satisfaction. With the current technological capability, social life has b een incorporated with the business aspect of running things. Companies have been compelled to adapt social media and the use of the internet to provide their services. Marketing and advertising have been forced to tap into the high usage of internet to make a large profit. With just under three billion people using the internet and over two billion people using smart phones, companies have resolved to a paradigm shifts. Some retail and distributing stores have moved from slightly depending on the internet to full dependence of the internet for all their services. Companies like Amazon and eBay who are also giant retailers have completely depended on online shoppers successfully for their sales. Primark has been reluctant to adapt to this marketing and sales strategies but has just kept the traditional walk in stores. This habit is however facing a challenge as more people change their shopping habit coupled with the various technological products that arise in the market. With Prima rkââ¬â¢s main target being people who are below thirty-five years of age, they are bound to adjust and shift into providing online shopping solutions for their clients. This is because it is estimated that the highest number of internet users are people who are below the age of thirty five years. This brings Primark head to head in confrontation and demand from its customers. With the global penetration of internet use, coupled with the increase in the use of mobile devices especially smart phones also creates the necessity to Primark of adoption an online shop. The demand in the usage of these solutions provides a huge market in the retail sector. Another factor that might make it inevitable for Primark to adopt the online retail shop is the use of social media marketing and internet marketing. Over one, half of Europeââ¬â¢s population has one or two active social media accounts. The usage of mobile phones and tablets has been very addictive and convenient at the same time. A large number of people rarely get the time to walk around, let alone spend time with their families. Online jobs and jobs that demand regular travelling or jobs which have squeezed time schedules create least chances for shopping to the affected people. This drives away all the interested clients that might have purchased the said products. Providing such clients with an alternative shopping model enables them to purchase the products online at any time. This not only stops the retailer from losing

International Monetary Economics Essay Example | Topics and Well Written Essays - 1500 words
International Monetary Economics - Essay Example One of the main fields of research which has attracted the attention of the researchers worldwide is the exchange rate and the trade balance relationship (Liew, Lim & Hussain, 2003, p.1). The elasticity model which is one of the most important models of balance of trade throws light on the prevalence of theoretical relationship between trade balance and rates of exchange of a nation (Stucka, 2004, p.22). There are a number of ways in which exchange rates can influence the trade balance of nations which provides valuable inputs to the nationââ¬â¢s policy makers to undertake exchange rate policies like devaluation policies etc in order to being about balance in the nationââ¬â¢s foreign trade. Devaluation increases the prices of foreign currencies making imports more expensive in the home nation till the foreign suppliers reduce their prices in order to compensate (International monetary economics-a, n.d., p.4). The reason why countries devaluates is to attain a competitive positi on in comparison to its competitors through the reduction of prices of goods produced domestically below the level which is compatible with the purchasing power parity (International monetary economics-b, n.d., p.5). ... This would be followed by a critical analysis through the presentation of a critical literature on the above aspects through which it tries to present the impacts of exchange rates adjustments on the balance of payments of nations. The monetary approach This approach is based on the fact that the disequilibrium in the balance of payments is based on the monetary disequilibrium which is the difference between the amount of money that individuals want to hold and the amount of money that the monetary authorities supply. In case the people want to hold more money, which exceeds the amount supplied by the Central Bank, then this would be met by a greater money inflow from abroad (Malik, 2006, p.2). The elasticity approach As per the views of Marshall, trade deficits lead to devaluation. Exports become more attractive in other nations. On the other hand the imports are made costlier in the domestic nation and this leads to the squeezing of the import bills. Trade deficits are thus elimina ted in the process (Sharan, 2011, p.121). The traditional approach The traditional approach deals more with the current account or the trade balance of nations. However, the approach does not consider the other components of the international accounts other than the current account. The balance of payments goes up along with the current account. However, since 1960s and the 1970s the traditional views have changed after studies emphasizing on factors determining the capital account flows (Arize, 2000, p.35). Critical Analysis Previous research reveals the importance of exchange rate fluctuations as a tool for international monetary regime. The comparison for seven of the largest non

Inca Empire Essay -- essays research papers fc
We know from history many various civilizations. Civilizations like Sumerian (4000 BC), Egyptian (3000 BC), Minoan (2000 BC), and Babylonian (1700 BC). Later, the Greek civilization, throughout the Macedonian empire, ranged as far east as northern India and as far south and west as Egypt. Then Romans were the rulers of the whole area from Constantinopole, to Palestine and North Africa to Britain. After centuries, the Vikings, people from what is now Norway, Sweden, and Denmark, established colonies in northern France, Sicily, England, and Ireland. During the 13th century AD, Mongols created a vast empire in Central Asia and the Mongol Empire controlled the expanse of territory from the Ural mountains in Russia to the Pacific Ocean. The same period of time another great civilization, called Ottoman Turks, was taking over most of North Africa, the Middle East, and the Balkan Peninsula. In America, Incas were the rulers of the largest native empire. Near the end of the 14th century the Inca empire began to expand from its initial base in the Cuzco region of the southern Andes, mountains of South America. Incasââ¬â¢ expansion ended with the Spanish invasion led by Francisco Pizarro in 1532. The Incas were the greatest indigenous civilization of the Americas. Within 100 years they had build a powerful empire, stretching the entire length of the Andeas, at a distance of more than 5,500 km. It was probably the greatest empire of its time life anywhere in the world, if we imagine that they had built a road system that extended some 30,000 to 40,000 km, unrivaled until the invention of the automobile, they possessed great skills in medicine, and they had a fully controlled social, political, and economical organization, although they lacked basic concepts such as the written language, the wheel, the steel, and the horse. In common with other Andean cultures, the Incas left no written records. Their history and their culture are known chiefly from the oral traditions preserved through the generations by official ââ¬Å"memmorizersâ⬠and from the written records composed from them after the Spanish conquest (Inca 375). The official language of the Inca Empire was the Quechua language. Eventhough the Spanish destroyed most Quechua cities and religious centers when they conquered the Inca Empire, many aspects of their way of life survive. There are about 10 million people in Per... ...of the Andes, and many thousands of tourists every year go there to see the impressive stone architecture the Incas erected among spectacular scenery. Because of records made by early Spanish and native chroniclers, we also know more about the Incas than about any earlier culture of the Andes. And, fortunately, through documentary research and archaeology, we continue to learn even more about the Incas and their achievements, such as their great road system, impressive architecture, elaborate ceremonies, and more.

Water issues in the Middle East
There are several factors that have caused such high demand in the Middle East. The water level is a lot shorter than most places and is increasing all the time. The region suffers from droughts every few years. The development of water resources is not making any progress factors such as cost, dealing with neighbouring countries which all delay the progress. Farming results in the highest level of water consuming at 80% leaving 20% for the Middle East. Cities such as Amman in Jordan ration its piped supplies; tankers deport the water which costs more than the poor can pay. The level of population growth is also increasing, which results in rising standards of living increasing the demand of water. The regions water is constantly in dispute. The regions water is spilt which results in confrontation and disagreements. ââ¬ËWater Wars' are improbable as three of the disputed river basins due to the uneven military powers are not equal. Egypt and Israel are downstream, Turkey is upstream and Iraq and Syria are also downstream. MAP SHOWING THE ROUTE OF THE EUPHRATES RIVER The Turkish purpose to use the water for an irrigation project in south-eastern Anatolia, this project will result in Syria's and Iraq's share of the Euphrates by 40% and 60%. This scheme is planned to revitalise the economy of the south east of the country. Eventually 22 dams in the Tigris and Euphrates rivers will provide irrigation and hydroelectric power to transform the local economy. They hope to gain the support from European companies, but in 2002 companies where forced to withdraw from the project, nevertheless Turkey has still continued to develop the dam. The dam will provide a clear positive outcome to the Middle East region. The water will be stored in the dam reducing the water flow, gradually allowing water through to the areas. The dam will provide jobs to the local community; this development will help the poorer citizens. Long term profit and economical issues may increase over the years as its helping the future for the water problems in the Middle East. Migrants will move into the area which may vary to a positive or negative outcome. The dam's main function is to provide hydro-electric power, which is more environmentally friendly. This will provide electricity to communities located around the Middle East. The energy provided is eco friendly and is reliable without using precious fossil fuels. With the new dam created larger business may move into the area, providing primary products to be distributed to other countries. This may provide more business to trade with the countries, developing the countries economical distributions. Although smaller business may lose money and go out of business resulting unemployment. The land used to create the dam, has resulted in angry local people. The local people have now received compensation funds. The amount of money put into the dam has been lost to local people, especially the few powerful landlords who each stand to collect huge compensation funds. Changes in rivers cycles will be vastly effected, rivers will lose millions of mà ¯Ã ¿Ã ½ of water being irrigated into cities located downstream from the upstream contributories. The Agriculture use dropped in all the area's creating a regional water market resulting for people paying for the water use. One example is the Yarmouk River which has a mean discharge of 400 million mà ¯Ã ¿Ã ½ a year, and provides almost half of Jordan's surface-water resources. The water in this river, after allowing some 17million mà ¯Ã ¿Ã ½ a yr for downstream users in the neighbouring countries providing agricultural water needs in the Jordan valley. This example has improved in the water use; this is similar situation to other rivers in the Middle East. Discharge is evenly distributed but resulted in higher levels of Agriculture. Area's downstream have resulted in less water being transported and reduced. Syria dam prevents water flowing restricting water flow to places such as Baghdad. Syria and Iraq have agreed to work together, after problems with bombing back in 1979. The political consequences have resulted in countries signing with each other separating themselves which could lead to future wars. Water extraction from the Euphrates has resulted in the government gaining a profit for charging them for the use of the water. This has also lead to the negative sentiment and response from the poorer citizens. Escalating growth of rising business increasing in the regions resulted in higher proceeds in the area. The government had to make a decision and verdict to their own areas to what they felt was overall best towards the people and for the future. Reponses won't be positive either way but never less the decision were what was felt most paramount and preeminent at the time.

Zion National Park Geology
Designated as Utahs first national park in 1909, Zion is a breathtaking display of nearly 275 million years of geologic history. Its colorfulà sedimentary cliffs, arches and canyons dominate the landscape for over 229 square miles and are a sight to behold for geologists and non-geologists alike. Colorado Plateau Zion shares a similar geologic background as the nearby Bryce Canyonà (~50 miles to the northeast) and Grand Canyon (~90 miles to the southeast) National Parks. These three natural features are all part of theà Colorado Plateauà physiographic region, a large, elevated layered cake of sedimentary deposits encompassing much of Utah, Colorado, New Mexico and Arizona. The region is remarkably stable, showing little of the deformation that characterizes the bordering Rocky Mountains to the east and theà Basin-and-Rangeà province to the south and west. The large crustal block is still being uplifted, meaning that the area is not immune to earthquakes. Most are minor, but a 5.8 magnitudeà quake caused landslides and other damage in 1992. à The Colorado Plateau is sometimes referred to as the Grand Circle of National Parks, as the high plateau is also home to Arches, Canyonlands, Captiol Reef, Great Basin, Mesa Verde and Petrified Forest National Parks.à Bedrock is easily exposed along much of the plateau, thanks to the arid air and lack of vegetation. The undeformed sedimentary rock, dry climate and recent surface erosionà make this area one of the richest troves of Late Cretaceous dinosaur fossils in all of North America. The entire region is truly a mecca for geology and paleontology enthusiasts. The Grand Staircaseà On the southwestern edge of the Colorado Plateau lies the Grand Staircase, a geologic sequence of steep cliffs and descending plateaus that stretches south from Bryce Canyon to the Grand Canyon. At their thickest point, the sedimentary deposits are well over 10,000 feet.à In this image, you can see that the elevation decreases in steps moving south from Bryce until it reaches the Vermillion and Chocolate Cliffs. At this point, it begins a gradual swell, gaining several thousand feet as it approaches the North Rim of the Grand Canyon. The lowermost (and oldest) layer of sedimentary rock exposed at Bryce Canyon, the Dakota Sandstone, is the top (and youngest) layer of rock at Zion. Similarly, the lowest layer at Zion, the Kaibab Limestone, is the top layer of the Grand Canyon.à Zion is essentially the middle step in the Grand Staircase.à Zions Geologic Story Zion National Parks geologic history can be broken down into four main parts: sedimentation, lithification, uplift and erosion. Itsà stratigraphic column is essentially a working timeline of the environments that existed there over the past 250 million years. The depositional environments at Zion follow the same general trend as the rest of the Colorado Plateau: shallow seas, coastal plains and sandy deserts. Around 275 million years ago, Zion was a flat basin near sea level. Gravel, mud and sand eroded down from nearby mountains and hills and was deposited by streams into this basin in a process known as sedimentation. The immense weight of these deposits forced the basin to sink, keeping the top at or near sea level.à Seas flooded the area during the Permian, Triassic and Jurassic periods, leaving carbonate deposits and evaporites in their wake.à Coastal plain environments present during the Cretaceous, Jurassic and Triassic left behind mud, clay and alluvial sand.à Sand dunes appeared during the Jurassic and formed on top of each other, creating inclined layers in a process known as crossbedding. The angles and inclines of these layers show the direction of the wind during the time of deposition. Checkerboard Mesa, located in the Canyonlands Country of Zion, is a prime example of large-scale horizontal cross-bedding.à These deposits, separated as distinct layers, lithified into rock as mineral-laden water slowly made its way through it and cemented the sediment grains together. Carbonate deposits turned into limestone, while mud and clay turned into mudstone and shale, respectively. The sand dunes lithified into sandstone at the same angles at which they were deposited and are still preserved in those inclines today.à The area then rose several thousand feet, along with the rest of the Colorado Plateau, during the Neogene period. This uplift was caused by epeirogenic forces, which differ from orogenic forces in that they are gradual and occur over broad regions of land. Folding and deformation are not normally associated with an epeirogeny. The thick crustal blockà that Zion was sitting on,à with over 10,000 feet of accumulated sedimentary rock,à remained stable during this uplift, tilting only slightly to the north.à Zions present day landscape was created by the erosional forces that resulted from this upheaval. The Virgin River, a tributary of the Colorado River, established its course as it traveled quickly down newly steepened gradients towards the ocean. Faster moving streams carried larger sediment and rock loads, which quickly cut away at the rock layers, forming deep and narrow canyons.à Rock Formations at Zion From top to bottom, or youngest to oldest, the visible rock formations at Zion are as follows:à Formation Period (mya) Depositional Environment Rock Type Approximate Thickness (in feet) Dakota Cretaceous (145-66) Streams Sandstone and conglomerate 100 Carmel Jurassic (201-145) Coastal desert and shallow seas Limestone, sandstone, siltstone and gypsum, with fossilized plants and pelecypods 850 Temple Cap Jurassic Desert Cross-bedded sandstone 0-260 Navajo Sandstone Jurassic Desert sand dunes with shifting winds Cross-bedded sandstone 2000 at max Kenyata Jurassic Streams Siltstone, mudstone sandstone, with dinosaur trackway fossils 600 Moenave Jurassic Streams and ponds Siltstone, mudstone and sandstone 490 Chinle Triassic (252-201) Streams Shale, clay and conglomerate 400 Moenkopi Triassic Shallow sea Shale, siltstone and mudstone 1800 Kaibab Permian (299-252) Shallow sea Limestone, with marine fossils Incomplete
