The United States of America (USA), commonly referred to as the United States (U.S.) or America, is a federal republic composed of 50 states, a federal district, five major territories and various possessions. The 48 contiguous states and Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is in the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The territories are scattered about the Pacific Ocean and the Caribbean Sea. At 3.8 million square miles (9.842 million km²) and with over 320 million people, the country is the world's third or fourth-largest by total area and the third most populous. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States are also extremely diverse, and the country is home to a wide variety of wildlife.

Mercedes-Benz Actros

The Mercedes-Benz Actros is a heavy duty truck introduced by Mercedes-Benz in 1995. It is normally used for long-distance haulage, heavy duty distribution haulage and construction haulage. It is available in weights starting at 18 tonnes and is powered by a V6 or V8 cylinder diesel engine with turbocharger and intercooler. Daimler Trucks/Lorries launched the version II of the Actros in 2002, and the version III in 2007.

Engine

The Mercedes Benz Actros is equipped with two types of engines. The OM 501 LA-541 and the OM 502 LA-542. The OM 501 is a 12-litre V6, and has outputs ranging from 310 HP to 460 HP. The engine management system employed by this engine is the PLD (Pumpe Leitung Duese-German abbr) which incorporates single plug-in pumps for each cylinder supplying fuel under pressure (up to 1,600 bar) to the injection valves. A control unit MR monitors all engine operating conditions via several sensors and varies the injection pressure to suit each operating condition.

Mexican–American War

A war between the U.S. and Mexico spanned the period from spring 1846 to fall 1847. The war was initiated by the United States and resulted in Mexico's defeat and the loss of approximately half of its national territory in the north. In the U.S. the war is termed the Mexican–American War, also known as the Mexican War, the U.S.–Mexican War or the Invasion of Mexico. In Mexico names for the war include Primera intervención estadounidense en México (United States' First Intervention in Mexico), Invasión estadounidense a México ("United States' Invasion of Mexico"), Guerra de la Invasión estadounidense, and Guerra del 47 ("The War of 1847").

After its independence in 1821 and brief experiment with monarchy, Mexico became a republic in 1824, characterized by considerable instability, so that when the U.S. initiated the conflict with the Centralist Republic of Mexico, Mexico was ill-prepared to respond. The war with the U.S. followed in the wake of decades of Indian raids in the north of Mexico, which Anglo-American migration to the Mexican province of Texas was aimed at buffering. Anglo-Americans and some Mexicans revolted against the Mexican government in the 1836 Texas Revolution, creating a republic not recognized by Mexico, which still claimed it as its national territory. The 1845 expansion of U.S. territory with its annexation of Texas escalated the dispute between the U.S. and Mexico into open war.

Politics of Mexico

The Politics of Mexico take place in a framework of a federal presidential representative democratic republic whose government is based on a congressional system, whereby the president of Mexico is both head of state and head of government, and of a multi-party system. The federal government represents the United Mexican States and is divided into three branches: executive, legislative and judicial, as established by the Political Constitution of the United Mexican States, published in 1917. The constituent states of the federation must also have a republican form of government based on a congressional system as established by their respective constitutions.

The executive power is exercised by the executive branch, which is headed by the President, advised by a cabinet of secretaries that are independent of the legislature. Legislative power is vested upon the Congress of the Union, a two-chamber legislature comprising the Senate and the Chamber of Deputies. Judicial power is exercised by the judiciary, consisting of the Supreme Court of Justice of the Nation, the Council of the Federal Judiciary and the collegiate, unitary and district tribunals.
