Astronaut Dr. Bernard Harris, Jr. Biography

Astronaut Dr. Bernard Harris, Jr. Biography Its no surprise that there are doctors who have served as NASA astronauts. They are well-trained and particularly suited to study the effects of space flight on human bodies. Thats exactly the case with Dr. Bernard Harris, Jr., who served as an astronaut aboard several shuttle missions beginning in 1991, after serving the agency as a flight surgeon and clinical scientist. He left NASA in 1996 and is a professor of medicine and is CEO and Managing Partner of Vesalius Ventures, which invests in healthcare technologies and related companies. His is a very classic American story of aiming high and reaching amazing goals both on Earth and in space. Dr. Harris has often spoken about challenges that we all face in life and meeting them through determination and empowerment.   Early Life Dr. Harris was born on June 26, 1956, the son of Mrs. Gussie H. Burgess, and Mr. Bernard A. Harris, Sr. A native of Temple, Texas, he graduated from Sam Houston High School, San Antonio, in 1974. He received a Bachelor of Science degree in biology from the University of Houston in 1978 before following that up with a doctorate in medicine from Texas Tech University School of Medicine in 1982. Beginning a Career at NASA After medical school, Dr. Harris completed a residency in internal medicine at the Mayo Clinic in 1985. He joined the NASA Ames Research Center in 1986, and focused his work on the field of musculoskeletal physiology and disuse osteoporosis. He then trained as a flight surgeon at the Aerospace School of Medicine, Brooks AFB, San Antonio, Texas, in 1988. His duties included clinical investigations of space adaptation and the development of countermeasures for extended duration space flight. Assigned to the Medical Science Division, he held the title of Project Manager, Exercise Countermeasure Project. These experiences gave him unique qualifications to work at NASA, where ongoing studies of the effects of spaceflight on the human body continue to be an important focus. Dr. Harris became an astronaut in July 1991. He was assigned as a mission specialist on STS-55, Spacelab D-2, in August 1991, and later flew on board Columbia for ten days. He was part of the payload crew of Spacelab D-2, conducting more research in the physical and life sciences. During this flight, he logged over 239 hours and 4,164,183 miles in space. Later, Dr. Bernard Harris, Jr. was the Payload Commander on STS-63 (February 2-11, 1995), the first flight of a new joint Russian-American space program. Mission highlights included the rendezvous with the Russian Space Station, Mir, operation of a variety of investigations in the Spacehab module, and the deployment and retrieval of Spartan 204, an orbiting instrument that studied galactic dust clouds (such as those where stars are born).  During the flight, Dr. Harris became the first African-American to walk in space. He logged 198 hours, 29 minutes in space, completed 129 orbits, and traveled over 2.9 million miles. In 1996, Dr. Harris departed NASA and received a masters degree in biomedical science from the University of Texas Medical Branch at Galveston. He later served as Chief Scientist and Vice-president of Science and Health Services, and then as Vice President, SPACEHAB, Inc. (now known as Astrotech), where he was involved in business development and marketing of the companys space-based products and services.

The Many Forms of Plurals

The Many Forms of Plurals The Many Forms of Plurals The Many Forms of Plurals By Mark Nichol Plurals take many (sometimes curious or counterintuitive) forms. Here is an outline of how to form various types of plurals according to the word form or ending: For words ending in: nonsibilant, or voiceless, consonants: add -s (dogs). voiced, or sibilant, consonant blends: add -es (riches). vowels: add -s (knees). -f: delete -f and add -ves (loaves) or -s (chiefs). -x: add -es (foxes). -y: delete -y and add -ies (bodies). For words of Latin or Greek origin ending in: -a: add -s or -e, depending on context (formulas/formulae). -ex: add -es or delete -x and add -ces, depending on context (indexes/indices). -ies: leave as is (species). -is: change to -es (axis). -ma: add -s or -ata, depending on context (stigmas/stigmata). -um: add -s (aquariums), delete -um and add -a (curricula), or either depending on context (mediums/media). -us: delete -us and add -i (alumni), -ii (radii), -era (genera), or -ora (corpora), or leave -us and add -es (octopuses) or use another form, depending on context (cactuses/cacti). Types of irregular forms include: ablaut, or mutated, plurals, with changes in the midst of a word (tooth/teeth; louse/lice). identical singular and plural forms (deer, spacecraft). -en and -ren endings (oxen, children). Some words have more than one plural form, one of which may be archaic (cows/kine) or reserved for a distinct meaning (dice/dies). One problematic category is in referring to fish in general and specific varieties of fish in particular: â€Å"Look at all the fish!† but â€Å"Gars are long, slender, predatory fishes.† Also, some types are given a distinct plural form (sharks, barracudas), though for others, the plural form is identical to the singular one (salmon, sturgeon). Plurals of letters, numbers, or abbreviations are generally formed simply by adding -s, although occasionally, the otherwise incorrect use of an interceding apostrophe is warranted (â€Å"Mind your p’s and q’s†). Usually, however, pluralizing names of letters requires no special treatment, especially when the letter is italicized, as here: â€Å"There are five es in beekeeper.† Initialisms and acronyms also require only an -s: â€Å"Many NGOs are headquartered here,† â€Å"It’s like having two NASAs.† The singular forms of some words are, because they end in s include gyros, kudos, and biceps (as well as triceps and quadriceps). The plural forms are the same, although the latter examples are also pluralized by adding -es. For other words, the original singular has been supplanted by a plural form used in both cases (alga by algae; graffito by graffiti). Want to improve your English in five minutes a day?
