Description of the Country: The United States of America (USA) commonly referred to as the United States (U.S.) or America, It is a federal republic composed of 50 states. The federal district of Washington, D.C., five major territories and various possessions the territories are scattered about the Pacific Ocean and the Caribbean Sea. United States is a federal republic country which has fifty states including five major territories and various outlying islands. The territories were separated from Pacific Ocean and the Caribbean Sea.
Geography of the country: The geographical sense, is the contiguous United States, the state of Alaska, the island state of Hawaii, the five insular territories of Puerto Rico, Northern Mariana Islands, U.S. Virgin Islands, Guam, and American Samoa, and minor outlying possessions. The United States shares land borders with Canada and Mexico and maritime borders with Russia, Cuba, and the Bahamas in addition to Canada and Mexico. At 3.8 million square miles and with over 320 million people, the country is the world's third largest by total area. The United States is the world's third or fourth largest nation by total area (land and water), ranking behind Russia and Canada and just above or below China the populated territories of Puerto Rico, American Samoa, Guam, Northern Mariana, and US Virgin Islands together cover 9,185 square miles.
Status of economy, research and development: The United States is the world's largest national economy in nominal terms and second largest according to purchasing power parity (PPP), representing 22% of nominal global GDP and 17% of gross world product (GWP). The relative increase in R&D and basic research of foreign nations as compared to the U.S. can (in some ways) work to the advantage of U.S. industry. The U.S. trading position in technology-oriented services remains strong as evidenced by the continued surplus in trade of computer software and manufacturing. The U.S. dollar is the currency most used in international transactions and is the world's foremost reserve currency The United States has a mixed economy The United States has been a leader in scientific research and technological innovation since the late 19th century. University of Chicago economists agreed, calculating in 2014 that workers in research and development add $5 to the GDP for each dollar they earn but finance industry workers cause the GDP to shrink by $0.60 for every dollar they are paid.
Jacob "Jack" Kevorkian was an American pathologist, euthanasia activist, painter, author, composer, and instrumentalist. Eighteenth century medicine was more sophisticated. In 1991, Heinz Hoenecke of the USA founded the volunteer organization called Pathologists. The first national pathology informatics conference in the USA took place in 1983 in Ann Arbor, Michigan, entitled Automated Information Management in the Clinical Laboratory (AIMCL).Pathology, through an abundance of autopsies, played an increasingly important role in this development. Many pathologic observations were published in textbooks and Pathology journals. From early days of the twentieth century to the present the pace of discovery and change has accelerated still more. Ongoing advances in the fields of fixation, embedding, cutting, immunohistochemical staining, molecular methods, microscopy, and image processing have continued to yield better diagnostic tools, and new, better, more precise diagnoses. Many new journals have appeared to report these findings, including sub-specialty journals covering the broadest reaches of pathology.
