David Lederman
David M. Lederman was an American aerospace engineer, entrepreneur, author, and humanitarian. He is noted for founding Abiomed, the company that developed AbioCor, the first fully implantable artificial heart. Biography Lederman was born in Bogota, Colombia to Israel Joseph Lederman and Rifka Lederman on May 26, 1944. His parents were immigrants who escaped the Nazis in Poland.

Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization. Spanish is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pancreatic Cancer
Pancreatic cancer arises when cell (biology), cells in the pancreas, a glandular organ behind the stomach, begin to multiply out of control and form a Neoplasm, mass. These cancerous cells have the malignant, ability to invade other parts of the body. A number of types of pancreatic cancer are known. The most common, pancreatic adenocarcinoma, accounts for about 90% of cases, and the term "pancreatic cancer" is sometimes used to refer only to that type. These adenocarcinomas start within the part of the pancreas that makes digestive enzymes. Several other types of cancer, which collectively represent the majority of the non-adenocarcinomas, can also arise from these cells. About 1–2% of cases of pancreatic cancer are neuroendocrine tumors, which arise from the hormone-producing neuroendocrine cell, cells of the pancreas. These are generally less aggressive than pancreatic adenocarcinoma. Signs and symptoms of the most-common form of pancreatic cancer may include jaundice, ye ...

Gaza Strip
The Gaza Strip (;The New Oxford Dictionary of English (1998) – p.761 "Gaza Strip /'gɑːzə/ a strip of territory under the control of the Palestinian National Authority and Hamas, on the SE Mediterranean coast including the town of Gaza...". ar, قِطَاعُ غَزَّةَ ' , he, רצועת עזה, ), or simply Gaza, is a State of Palestine, Palestinian Enclave and exclave, exclave on the eastern coast of the Mediterranean Sea. The smaller of the two Palestinian territories, it borders Egypt on the southwest for and Israel on the east and north along a border. Together, the Gaza Strip and the West Bank make up the State of Palestine, while being under Israeli-occupied territories, Israeli military occupation since 1967.

Artificial Heart
An artificial heart is a device that replaces the heart. Artificial hearts are typically used to bridge the time to heart transplantation, or to permanently replace the heart in the case that a heart transplant (from a deceased human or, experimentally, from a deceased genetically engineered pig) is impossible. Although other similar inventions preceded it from the late 1940s, the first artificial heart to be successfully implanted in a human was the Jarvik-7 in 1982, designed by a team including Willem Johan Kolff, William DeVries and Robert Jarvik. An artificial heart is distinct from a ventricular assist device (VAD; for either one or both of the ventricles, the heart's lower chambers), which can be a permanent solution also, or the intra-aortic balloon pump – both devices are designed to support a failing heart. It is also distinct from a cardiopulmonary bypass machine, which is an external device used to provide the functions of both the heart and lungs, used only for a ...

Bogotá
Bogotá (, also , , ), officially Bogotá, Distrito Capital, abbreviated Bogotá, D.C., and formerly known as Santa Fe de Bogotá (; ) during the Spanish period and between 1991 and 2000, is the capital city of Colombia, and one of the largest cities in the world. The city is administered as the Capital District, as well as the capital of, though not part of, the surrounding department of Cundinamarca. Bogotá is a territorial entity of the first order, with the same administrative status as the departments of Colombia. It is the political, economic, administrative, and industrial center of the country. Bogotá was founded as the capital of the New Kingdom of Granada on 6 August 1538 by Spanish conquistador Gonzalo Jiménez de Quesada after a harsh expedition into the Andes conquering the Muisca, the indigenous inhabitants of the Altiplano. Santafé (its name after 1540) became the seat of the government of the Spanish Royal Audiencia of the New Kingdom of Granada (cre ...

AbioCor
AbioCor was a total artificial heart (TAH) developed by the Massachusetts-based company AbioMed. It was fully implantable within a patient, due to a combination of advances in miniaturization, biosensors, plastics and energy transfer. The AbioCor ran on a rechargeable source of power. The internal battery was charged by a transcutaneous energy transmission (TET) system, meaning that no wires or tubes penetrated the skin, reducing the risk of infection. However, because of its size, this heart was only compatible with men who had a large frame. It had a product life expectancy of 18 months. AbioCor was surgically introduced into 15 total patients, 14 of them during a clinical trial and one after FDA approval. However, due to insufficient evidence of its efficacy, AbioMed abandoned further development of the product. History AbioMed began development of the AbioCor device in the 1990s, beginning animal studies in 1998 in preparation to demonstrate readiness for formal clinical ...

Aerospace Engineering
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, Air propulsion, avionics, materials science, stru ...
