The planet Mars Essay Example for Free

The planet Mars Essay The atmosphere above the surface of Mars is about 100 times less dense than the atmosphere of Earth. The Martian atmosphere is dense enough to support a weather system that includes clouds and winds. According to experts, Mars roller coaster-like weather is more chaotic and unpredictable than scientists first thought. At times, the sky can appear pink and cloudless, filled with windblown dust raised from the rusty Martian surface. Tremendous dust storms sometimes rage over the entire planet. Most of the dust storms occur during the perihelion when Mars is closest to the sun. In addition, the dust storms continue to dominate the atmosphere and climate during the aphelion when Mars is furthest from the sun. Perihelion and aphelion occur every Mars year, which equals two Earth years. (Mars Atmosphere, 2002) Mars is much colder than Earth. The average temperature on Mars is about -80  °F (-60  °C).Temperatures at the Martian surface vary from as low as about -195  °F (-125  °C) near the poles during the winter to as much as 70  °F (20  °C) at midday near the equator. (Mars Science, 2000) These shifts in climate are caused by three factors: Mars thin atmosphere, its elliptical orbit around the sun, and strong climatic interactions between dust and water ice clouds in the atmosphere. Mars atmosphere is so thin that it weighs less than 1 percent of Earths atmosphere. Because Mars atmosphere is so paper-thin and there are no oceans to store up heat from the sun, the planets temperatures respond more quickly and intensely to surface changes and atmospheric heating by the sun. There are also much larger annual changes in sunlight falling on Mars than on Earth, because Mars distance from the sun varies by 20 percent in its orbit around the sun every two years. (Mars Science, 2000) Mars has many of the kinds of surface features that are common on Earth. These include plains, canyons, and volcanoes. Overall, craters occur throughout the surface of Mars, while they are rare on Earth. In addition, fine-grained reddish dust covers almost all the Martian surface. Many regions of Mars consist of flat, low-lying plains. Most of these areas are in the northern hemisphere. They may be so smooth because they were  built up from deposits of sediment. There is evidence that water once flowed across the Martian surface. The water would have tended to collect in the lowest spots on the planet and thus would have deposited sediments there. Near the equator of Mars, there are is a string of canyons known as Valles Marineris. Scientists believe that they were formed by the crust of the surface being stretched and ultimately split. Volcanoes appear throughout the planet. Many of these volcanoes resemble volcanoes that are in Hawaii. Their slopes rise gradually and they are referred to as shield volcanoes. They were formed from eruptions of lavas that can flow for long distances before solidifying. (The Surface of Mars, 2002) Martian craters are similar to craters on Earths moon. The craters have deep, bowl-shaped floors and raised rims. Some large craters have central peaks that form when the crater floor rebounds upward after an impact. Much of the surface of the southern hemisphere is extremely old, and it contains many craters. Other parts of the surface, especially in the northern hemisphere, are younger and thus have fewer craters. (Mars, 2002) References The Surface of Mars. (2002). Canyons and plains. [Online].

Effect of Vegetation on Slope Stability

Effect of Vegetation on Slope Stability 5.1 Introduction Incorporating the vegetation effect in slope stability has been used for many years in geotechnical engineering. The vegetation effect on slope stability usually ignored in conventional slope analysis and it is considered as a minor effects. Although the vegetation effect on slopes qualitatively appreciated after the pioneer quantitative research. The vegetation cover is recognized in urban environment and it is generally utilized along transportation corridors such as highways and railway, river channels, canals, mine waste slopes and artificially made sloping ground. There are some remedial techniques for soil stabilizations in civil engineering practice such as geosynthetic reinforcement or soil nailing are often used at slopes at great expense, but now many parts of the world considered sustainable alternative methods such as using the vegetation cover or soil bioengineering in civil engineering applications. This method reduces the cost and local labour force and it is environmental friendly method. The vegetation cover, the roots draw out moisture from soil slopes through evapo-transpitation leads to shrinking and swelling in soil. After prolonged wet and dry period, it is possible to foam cracks at dry period due to reduction of moisture content from vegetation covers. 5.2 Influence of vegetation The vegetation effect influence on soil slopes, generally classified into two types, they are mechanical and hydrological effects. The hydrological effect is responsible for soil moisture content, increasing the evapo-transpiration and resulting increasing the soil matric suction. Water is removed from the soil region in several ways, either evaporation from the ground surface or by evapo transpiration from vegetation cover. The process produces upward flux of the water out of the soil. The mechanical effects from the vegetation root responsible for physical interaction with soil structure 5.2.1 Hydrological effects The influence of vegetation cover in soil moisture content in different ways. The rain water evaporates back to atmosphere ultimately reduce the amount of water infiltrate into the soil slope. The vegetation roots extract moisture from the soil and this effects leads to reducing the soil moisture content. The reduction in moisture content in soil, it will help to increase the matrix in unsaturated soil or decrease the pore water pressure condition in saturated soil. Both of this action ultimately improves the soil stability. The vegetations moisture reduction ability is well recognized. The root reinforcement is most important factor, it is generally considered in vegetation effects on slope analysis, thought the recent studies shows the importance of hydrological effects on slopes by Simon Collision (2002). They studied the pore water pressure and matric suction in soil over for one cycle of wet and dry cycle under different vegetation covers. This result shows the significant effec ts of vegetation hydrological effects are soil structure. 5.2.2 Mechanical effects The vegetations root matrix system with high tensile strength can increase the soil confining stress. The soils root reinforcement is described with roots tensile test and adhesional properties. The additional shear strength of soil is given by the plant root bound together with the soil mass by providing additional apparent cohesion of the soil. The slope contain large trees need to consider the weight of the tree. The additional surcharge to the slope may give from larger trees. This surcharge increases the confining stress and down slope force. The surcharge from larger trees could be beneficial or adverse condition depending of the location on soil slope. If the trees located slope toe, the slope stability will be improved due to additional vertical load. On the other hand, if the trees located at upper surface of the slope, hence overall stability reduced due to vertical down slope force Furthermore, the wind loading to larger trees increasing the driving force acting on the slope. In the wind load is sufficiently large it may create the destabilizing moment on the soil slope from larger trees. Larger trees roots penetrate deeper strata and act as stabilizing piles. The effects of surcharge, wind loading and anchoring usually considered only larger trees. 5.3 Vegetation effects on soil slope numerical study In this parametric study, the effect of vegetation on the stability of slope has been investigated using the SLOPE/W software tool. In this study only consider the parameter root cohesion known as apparent root cohesion (CR). This coefficient incorporated with Mohr-Coulomb equation. 5.3.1 Model geometry 20 m 10 m 20 m 10 m 20 m Figure 5. 1 Slope geometry à ¯Ã‚ Ã‚ §Ãƒ ¯Ã¢â€š ¬Ã‚  Ãƒ ¯Ã¢â€š ¬Ã‚ ½Ãƒ ¯Ã¢â€š ¬Ã‚  20 kN/m3 c = 15 kPa à ¯Ã‚ Ã‚ ¦Ãƒ ¯Ã¢â€š ¬Ã‚ ½Ãƒ ¯Ã¢â€š ¬Ã‚  20 °In this parametric study 10 m height 2:1 homogenous slope (26.57 °) is used to investigate the vegetation effect on stability analysis, as shown in Figure 5.1.

Vegetation cover plays a significant role in slope stability analysis. The root cohesion experiments from various researchers over the past three decades results are shown in Table 5.1. In this research only consider the grass and shrubs root reinforcement. The apparent root cohesion range is 1 kPa to 5 kPa. If we consider the bigger trees in slopes need to consider its weight for slope stability calculations. The Table 5.2 shows the factor of safety analysis results for different root cohesion for different depths. Figure 5. 4 Different root cohesion (CR ) values for factor of safety for different root depths The analysis carried out with the software tool SLOPE/W. The graph shows the influence of vegetation cover i.e. root cohesion (CR) and its root depth (hR). The soil slope without any vegetation cover (CR = 0 kPa), the factor of safety is 1.570. This result shows the vegetation cover applied entire surface. The factor of safety linearly increase when increase with the root cohesion and root depth.

Structure and Aerodynamics of SAAB 340 Series Aircraft

Structure and Aerodynamics of SAAB 340 Series Aircraft The following report will contain information on the SAAB 340 series aircraft in regards to its structure, aerodynamics, propulsion, operation and safety throughout its history (1970s-2017) Introduction The SAAB 340 is a regional aircraft series designed by the Swedish aerospace manufactures with the desire to explore commercial airliners with 30-40 passengers in the 1970s, originally named the SAAB 340A. The plane was selected to run with GE turboprop engines due to their inherent fuel economy compared to a turbofan or turbojet engines. The SAAB 340B was the first development of the SAAB 340A, the newer aircraft had more powerful engines, a larger tail plane and the crafts range and take-off weight where increased. The SAAB 340s ceased production in 1998 with lack of interest from airliners and hence profits reduced. The SAAB 340 has many renditions the most common being the 340A, 340B, 340B plus including carbo, corporate and commercial interior designs. Of note is that originally SAAB AB and Fairchild (an American company) co designed the 340, having the original name of the SF340, Fairchild designed wings, wing mount nacelles and empennage. The SAAB 340 can be defined as a monoplane with a tractor engine setup. It has a tricycle wheel layout and a conventional tail. The wings are dihedral, low mount, tapered and cantilevered from the fuselage with a single spar. Some of these are further investigated below. It would also be of note to mention the SAAB 340B (most common variant of SAAB 340s) has seating typically for 34 passengers where their weight with baggage is 214lbs, a fact sheet with the aircraft data and statistics will be attached in the appendix. Structure and Construction The SAAB 340 uses common and unusual structural components during its 40+ year service, some of the features which has characterised the aircraft is its single spar wing design, cable strengthen tail plane and a metal bonded skin. These structural components used by SAAB AB to maintain the range of their aircraft whilst also increasing range and payload. The SAAB 340 uses a single spar wing which inserted behind the leading edge which allows for the complexity of the wing to be reduced compared to a multi spar wing. This is beneficial in the construction of a regional aircraft due to the reduced in cost in regards to the difficulty in which it is to design and then build a multi spar wing. The single spar also allows for more free space in the wing interrupted only by the ribs which are designed to have holes in them to reduce weight and allow for usable space (fuel and control surface actuators) in the aircraft, see figure 3 in the appendix. The single spar in the tapered wing also allows for a slender trailing edge of the aerofoil which can be further explored in the aerodynamical section of this report. The SAAB 340 uses a unique feature for a commercial airliner to use, a cable was installed from the top of the empennage to another, the unique design will be further explored below however the cable installed on the 340A is a unique structural component using the cables tension to give the wing added structural rigidity. The newer 340B and B plus dont have the cable installed, which may be due to lighter and stronger longerons or ribs or better engineered surfaces like metal bonding which is used to cover over 40% of the aircrafts external surfaces. The use of metal bonding in its surface skin reduces weight and increases the structural integrity of the aircraft. This increased rigidity in the surface allows for the aircraft to be designed with less internal bracing and material weight. By incorporating the structural benefits of an aluminium bonded skin into the aeroplane, SAAB AB and the Engineers can best maximise the range, interior space and payload. The SAAB 340 is made up of common modern aircraft parts and features, the fuselage and wings are made from aluminium ribs, spars, longerons and stringers which although not unique take advantage of the lightness of aluminium and its structural strength compared to a point 3% carbon steel or an expensive composite equivalent. The SAAB AB engineers therefore had to make the most of cheaper but most effective materials to keep costs lows for consumers of the regional aircraft but still have a light and fuel efficient aeroplane to make regional distance with 30-40 passengers as per the original design specifications. The structural aspects of the aircraft are important in making the SAAB 340 maximise its space and payload, the engineers therefore had to combine techniques like tension in cables and intelligently designed wings which will minimise weight but still comply with complex fluid flow around the fuselage and aerofoils as well as can be keep passengers safe and comfortable. Aerodynamics The SAAB 340, like all modern aircraft, is designed to minimise drag whilst maximising lift. The SAAB AB aircraft uses intelligent and mandatory aerodynamics and aerodynamical systems on their aircraft; a unique tail plane, parabolic nose and fuselage shape and the wings shaping plus engine integration. The SAAB 340 has a conventional empennage, where the vertical stabilizer has two parts, highlighted in figure 4 of the appendix. SAAB AB has incorporated this design in the 340 and their 2000 series aircraft. The two stages in the vertical stabiliser helps to create a more stable and streamlined laminar flow structure around the stabiliser and hence allows for the rudder to be more effective in controlling the airflow around it. The SAAB 340 has a typical airliner style parabolic nose cone which leads into a straight circular fuselage (minus the V shape wing mount nacelles on the bottom of the aircraft, shown on figure 6). The parabolic nose cone is highly efficient in having the air flow move around the aircraft without inducing large quantities if air resistance and drag. Further SAAB AB have slimmed the rear of the plane into a point, typical of modern airliners in an effort to have the air flow coming off the aircraft in a low drag streamlined structure. The SAAB 340 uses a tapered, cantilevered, dihedral wing (as mentioned above) and has an equally cantilevered dihedral horizontal stabiliser both of which have aerodynamic features of no winglets, small cross sectional height as well as the wings having been integrated with the engine. The lack there of winglets on the SAAB 340 highlights how the engineers have been able to reduce the mixing of air from the top and bottom of the aerofoil. The usual effect of winglets will create a barrier, not allowing for the high and low speed air flow to create drag and vortexes. SAAB AB have been able to sculpt their aerofoils so that the need for a winglet has been reduced, a technique used by Boeing, on the 747 for example. The SAAB 340 has also integrated their GE turboprop engines into the wing design. This is seen in figure 6 of the document particularly in the front view, where the engine has been slotted into the wing and has allowed for the turboprop to be elegantly and aerodynamically efficiently positioned to reduce the drag which can occur from having an engine hang off the wing. This fitted setup also gives the operational functionality of the aircraft as the retractable undercarriage is also integrated into the engine area. This innovative solution for SAAB AB engineers has allowed for the aircraft to have a retractable undercarriage but keep stability on a runway, giving the SAAB 340 aerodynamically efficient flight and hence fuel efficient flight too. The SAAB 340B+ differs from the 340B due to its extended wingtips which allows for it to be more aerodynamically efficient in more humid environments and to be able to take off on shorter runways, this variation in wing design of the different models gives the aircraft additional enhancements is rural and regional areas where the flying environment isnt ideal. Propulsion The SAAB 340 uses GE turboprop engines with a 4-propeller prop from Dowty Rotol or Hamilton Sundstrand, differences in noise given in figure 5 of the appendix. The SAAB 340B uses the GE CT7-9B, pictured in figure 6 of the appendix, which has an 1870 shp rating [5]. Figure 8 a cutaway of the CT7-9B turboprop [6] The turboprop engine used by the 340 is highly efficient engine with high range for its size. The engine can fly a maximum 470nm with a maximum total weight in excess of 29000lb (take off) on under 6000lb of fuel. The two engines can thrust the SAAB 340B and B Plus at 283 knots at an altitude of 25000 feet. Further information on range and payload is in figure 9 of the appendix. The SAAB 340 has used different engines over the years, originally running CT7-5A2 turboprops the change to a CT7-9B led to an increase in the SHP of the engines, more power, and an increase in fuel efficiency. More so, it is of current note that the SAAB 340B has had recent engine and propeller failures with REX region airlines in Australia. The failure of a Turboprop engine on the 23rd of march 2017 and a propeller falling off mid-flight on the 17th of march 2017. However due to intelligent engineering on behalf of SAAB AB the two planes could fly on one of the turboprops and make a safe emergency landing. Thus, highlighting both the aerodynamic design quality of the aircraft and how the GE CT7-9B engine can still power the aircraft with only half available thrust. Operation Requirements The SAAB 340 requires a runway, crew and a form of refuelling at destination/departure. Due to the SAAB 340s design the aircraft has been deliberately constructed with regional and rural travel in mind where infrastructure is low and basic hence the 340 has built in facilities such as stairs and extra additions for the craft to cope and work in weather of the extremes and on runways made of gravel and dirt. The SAAB 340B has extras such as the gravel pack and longer wingtips which allow for it to operate in humidity and heat without larger runways or advanced asphalt airports [8]. The SAAB 340B requires, at SL with optimal flaps and at ISA, a runway of 4220ft (1.3km) however at less optimum environments the runway needed can be 6690ft (2.02km). The SAAB 340 does require 2 pilots and one flight attendant can be also apart of the crew. Die to the small seating numbers the SAAB 340 doesnt have room for more than one attendant. The floor plan is shown below highlighting where the crew is stationed on a typical 340 layout. Figure 10 SAAB 340 layout as intended by SAAB AB [4] Safety Record The SAAB 340 has a rather good incident record with only four flights ending in fatalities, however this is considered four times to many. The below table makes note of the four fatal incidents of the SAAB 340 [9] Fatal Incidents Year Airline and Flight Fatalities Reason 1994 KLM city hopper 433 3 The Engine Stalled and the Aircraft struck the ground, the Aircraft broke upon impact 1998 Formosa Airlines 13 The Aircraft has electrical faults and the Crew was disorientated, the plane crashed in the ocean 2000 Crossair 498 10 The Aircraft banked to steep causing a spiral dive and resulted in the aircraft crashing 2011 SOL LÃ ­neas AÃ ©reas 5428 22 The Aircraft whilst flying at FL179 began to pick up ice accretion and by the time the plane descended to FL140 the ice was to server causing the crash The SAAB 340 has had successfully operated for many years with only few fatal accidents which is a testament to the engineering behind the aeroplane however aircraft isnt without incident. Most recently Australian regional aircraft carriers Rex regional airlines has had two engine issues. Firstly, on the 17th of march 2017 the propeller fell off the turboprop engine, followed by the 23rd where the engine on the starboard side came up with warnings causing it to land. These two recent examples showcase how even in extreme circumstances where 50% of the planes engines have been rendered useless the pilots can fly the regional airliner safely to an airport to land. Some other notable instances of the SAAB 340B having mid-air issues include a recent Western Air plane crash at Grand Bahama International Airport where following take off the plane experienced issues with its undercarriage and was forced into an emergency landing where the undercarriage then gave way, the intelligent design of fuselage floor and turboprop-wing integration allowed for the plane to stop without causing any major injuries to the passengers [11]. Conclusion The SAAB 340 series was designed in the 1970s as a cost effective and effect aircraft for SAAB AB to explore commercial aviation, this venture led to one of the most successful regional airliners with more units being sold than any other during its 40-year service history. The structural, aerodynamic and propulsion features although common place in aviation demonstrate the design of the 340 as a simple and effective flyer. The 340 series has basic crew and infer structure requirements however this has allowed for it to fly from city to city and onto the county without changing the undercarriage. Coupled with it relative susses in terms of safety the SAAB 340 is a proven reliable aircraft.

The Japanese Bureaucracy :: Japan Politics Government Essays Papers

The Japanese Bureaucracy Japanese bureaucracy has a large power towards Japanese politics. In 1955, Liberal Democratic Party is established and controlled Japanese politics as the government ruling party until 1994. This year is when Social Democratic Party of Japan took a position as the government ruling party. Still the constitution of bureaucratic politics in Japan was not changed even though a different type of political party was leading the government. However, Liberal Democratic Party began to take a government ruling position again since 1996 when Hashimoto became a Prime Minister of Japan until the resignation during this summer due to incapable deal with Asian economic crisis. In "In Defense of Japanese Bureaucracy", Peter F. Drucker argued that American policy towards Japan during Asian economic crisis are dubious even though intelligent people such as American policy makers, Japanese scholars are made with their knowledge that are related to the nature of Japanese government that is bureaucratic system. The reason is that American could not assume in a right way because American tried to defend Japanese bureaucratic system totally and this is very rare that Japan depends totally on bureaucratic system all over the world as a developed country. According to Drucker, still this is a universal custom in all developed countries including the United States. The main questions about Japanese bureaucracy are why Japan is still continuing bureaucratic politics and how Japanese bureaucracy is working. Also, how Japanese bureaucracy is different from those in the West and how Japanese bureaucratic system reflects towards all over the world as one of major powers. Japanese bureaucracy had less control of business and the economy than Europeans' counterparts in 1970s because between in the late 1960s to early 1970s, Japanese bureaucracy is failed to comply with high technology of information system. Japanese bureaucracy is failed again in the late 1980s due to the pop of "bubble" economy in Japan. The necessity to care about Japanese bureaucracy is that Japan is the second largest economic power all over the world and from this fact, the position of Japan is very important in world politics. Japan has a large influence towards world politics and economy. On the contrary, Japanese bureaucracy is successful in economically due to using protectionism. For example, the United States took a position as liberalism that is also called free trade, but Japanese government created the Ministry of International Trade and Industry and let them to control most of the foreign trade among nations.

Gertrude Stein Essay -- Biography Essays

Gertrude Stein Gertrude Stein is one of the most celebrated authors and patrons of the arts. She encouraged, influenced and aided many literary and artistic figures through her support, investment and writings. Stein was born on February 3, 1874 into upper middle class surroundings in Allegheny, Pennsylvania. When she was 3 years old the family moved to Vienna and then on to Paris before returning to America in late 1878. Gertrude and her brother Leo became very close although he was two years her senior. They found like interests and became devoted allies through much of their early lives. Stein was eight years old when she made her first attempt at writing. Reading became an obsession for her beginning with Shakespeare and books on natural history.[2] In school she was fascinated with the structuring of sentences. She once said, â€Å""I suppose other things may be more exciting to others...I like the feeling the everlasting feeling of sentences as they diagram themselves.[3]" In 1904 she moved in with her brother Leo at 27 Rue de Fleurus which would become the meeting place of many writers, artists, critics and people drawn by her reputation. Her brother and she also began collecting paintings by Renoir, Gaughain, Picasso (who later painted her portrait), Cezanne, Baraque, Matisse and others[4]. The â€Å"Salon,† as their home came to be called, had paintings literally covering every wall. They had dinner parties every Saturday night and the â€Å"Salon† became a sanctuary for artists and writers. It became so popular that Stein had to begin writing late at night after all the other guests had departed. Her literary and artistic judgments were revered, and her chance remarks could make or destroy reputations.[5] A... ...bdominal pains which would be diagnosed as colon cancer a few months later. She was rushed to the hospital on July 19, 1946 and made her will on the 23rd leaving the bulk of her estate to Alice. On the 27th before being wheeled into emergency surgery her last words were spoken to Alice. "What is the answer? ...without a reply, "In that case...what is the question[11]?"

Which level of government should take the lead?

In ascertaining which between the federal government and the state and local government can best address the problems facing this nation, it is important that the pressing problems of the United States of America be identified first. Evidently, the most pressing problems of our nation today include job creation and economic growth, the war in Iraq, health care and social security, energy and the cost of gas, terrorism, illegal immigration and environment and global warming.When it comes to addressing the problem of job creation and economic growth, the lead should not be taken by any of the two levels of government since both the federal as well as the state governments must share the burden of dealing with the same. At the state or local level, intrastate commerce must be readily addressed. While interstate commerce must be facilitated by the federal government.The federal government however must be permitted to take the lead in addressing the problems of the war in Iraq, terrorism, illegal immigration energy and the cost of gas and the environment and global warming as these problems substantially involves foreign policy works that only the federal government is empowered to do. These problems require immediate attention and may oftentimes necessitate instant action which may only be delivered by the national government.On the other hand, the problems of health care and social security must be addressed by the state and local governments for the identification as well as the cure to these problems can best be addressed locally. It is within the realm of the power of the state and local governments to make measures to attend to the problems of health care and social security. Discuss the Davis Administration and how it affected the writing of the 1876 Texas Constitution.Governor Samuel Jackson Davis’ administration was perhaps the most controversial and unpopular one in Texas history. This may be because even his assumption to office was in the first in stance questionable. The backbone of his administration was the Texas Constitution of 1869 which provided for the centralization of power into the Governor’s Office and the expansion of governmental power. Davis’ term lengthened from the original two years to four years and his salary was significantly increased.Davis was able to have control over local state officials because of the vast appointing and removal powers granted to him by the constitution. The Davis administration was also criticized for levying unreasonably high taxes and incurring lavish government expenditures. Aside from his control over the State Police, the Constitution also empowered Davis to take charge of the State Militia which he both used to maintain law and order and compel local officials whenever they refused or failed to obey.His unpopularity was bolstered by immense corruption coupled with his declaration of martial law in some counties. Texans have always preferred decentralization, chea per government spending and abhorred the coercive force of the state police and the state militia and the declaration of martial rule. That is why in December of 1873, Texans replaced Governor Davis with a Democrat in the person of Richard Coke and subsequently rewrote their constitution.Texans promulgated the Constitution of 1876 which, up to this time, remains to be the fundamental organic law of Texas. It provided for shorter terms and lower salaries of elected officials, obliteration of voter registration, local control of schools, low taxation and less government expenditure. Although the governor was given the power to appoint, fill vacancies, and enforce the laws of the land, he was not given control over local or other elected state officials. The 1876 Texas Constitution vastly differed from its predecessor constitution. References: Longley, Robert. â€Å"Federalism: National Vs. State Government.†Ã‚   (2008). April 28, 2008 .

Spanish Language and Latin America

1 International Baccalaureate History of the Americas HL Required Summer Reading Study Guide Born in Blood and Fire: A Concise History of Latin America By John Charles Chasteen Foreign Affairs November/December 2000 states: Born in Blood and Fire is a briskly written yet sophisticated introduction to Latin America that will be greatly welcomed by non-specialists and experts alike. Chasteen paints on a very broad canvas, but he succeeds in capturing with enviable conciseness the major ingredients of Latin America's uniqueness and complexity.Especially welcome is his graceful integration of Brazil into the overall picture, which general histories of Latin America often lack. He first takes the reader from the European conquest through the colonial consolidation by Spain and Portugal before looking at the role of indigenous communities in the new order imposed by the Europeans and African slavery's social and cultural consequences. He then follows with the independence movements and the uneven attempts at nation-building in the nineteenth century; race, ethnicity, religious and liberal ideologies, and the roles of key individuals are also covered.Chasteen concludes with the recent return to economic liberalism, this time in the context of open elections, continuing poverty, and social exclusion of large segments of the population. A stellar performance! Summer Reading Directions: The answers to these questions should be well thought out, typed, 12 point font, single spaced, New Times Roman. The completed review sheet is a summer long process that is not designed and should not be attempted at the last minute.
