A. Carl Leopold
Aldo Carl Leopold (December 18, 1919 – November 18, 2009) was an American academic and plant physiologist, son of Aldo Leopold, a noted ecologist. He is known for his research on soybeans which led to techniques allowing insulin to be dried and later processed into an inhalable insulin. Early life and education Aldo Carl Leopold was born to Aldo Leopold, a noted ecologist and employee of the United States Forest Service, and Estella Leopold in Albuquerque, New Mexico as the 4th of 5 children. Career Leopold received a bachelor's degree in botany from the University of Wisconsin in 1941. He enlisted in the Marines during World War II and served in the Pacific as defense counsel in courts-martial for soldiers who were charged with being AWOL. After his discharge, Leopold received MS and PhD degrees in plant physiology from Harvard University, studying under Kenneth Thimann. He worked briefly for the Hawaiian Pineapple Company, and then joined the faculty of Purdue University ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albuquerque
Albuquerque ( ; ), ; kee, Arawageeki; tow, Vakêêke; zun, Alo:ke:k'ya; apj, Gołgéeki'yé. abbreviated ABQ, is the most populous city in the U.S. state of New Mexico. Its nicknames, The Duke City and Burque, both reference its founding in 1706 as ''La Villa de Alburquerque'' by Nuevo México governor Francisco Cuervo y Valdés''.'' Named in honor of the Viceroy of New Spain, the 10th Duke of Alburquerque, the city was an outpost on El Camino Real linking Mexico City to the northernmost territories of New Spain. Located in the Albuquerque Basin, the city is flanked by the Sandia Mountains to the east and the West Mesa to the west, with the Rio Grande and bosque flowing from north-to-south. According to the 2020 census, Albuquerque had 564,559 residents, making it the 32nd-most populous city in the United States and the fourth largest in the Southwest. It is the principal city of the Albuquerque metropolitan area, which had 916,528 residents as of July 2020, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbohydrate
In organic chemistry, a carbohydrate () is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula (where ''m'' may or may not be different from ''n''), which does not mean the H has covalent bonds with O (for example with , H has a covalent bond with C but not with O). However, not all carbohydrates conform to this precise stoichiometric definition (e.g., uronic acids, deoxy-sugars such as fucose), nor are all chemicals that do conform to this definition automatically classified as carbohydrates (e.g. formaldehyde and acetic acid). The term is most common in biochemistry, where it is a synonym of saccharide (), a group that includes sugars, starch, and cellulose. The saccharides are divided into four chemical groups: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides and disaccharides, the smallest (lower molecular wei ...

Plant Physiologists
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

21st-century American Botanists
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emperor, a ...

American People Of German Descent
German Americans (german: Deutschamerikaner, ) are Americans who have full or partial German ancestry. With an estimated size of approximately 43 million in 2019, German Americans are the largest of the self-reported ancestry groups by the United States Census Bureau in its American Community Survey. German Americans account for about one third of the total population of people of German ancestry in the world. Very few of the German states had colonies in the new world. In the 1670s, the first significant groups of German immigrants arrived in the British colonies, settling primarily in Pennsylvania, New York and Virginia. The Mississippi Company of France moved thousands of Germans from Europe to Louisiana and to the German Coast, Orleans Territory between 1718 and 1750. Immigration ramped up sharply during the 19th century. There is a "German belt" that extends all the way across the United States, from eastern Pennsylvania to the Oregon coast. Pennsylvania, with 3.5 milli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purdue University Faculty
Purdue University is a public land-grant research university in West Lafayette, Indiana, and the flagship campus of the Purdue University system. The university was founded in 1869 after Lafayette businessman John Purdue donated land and money to establish a college of science, technology, and agriculture in his name. The first classes were held on September 16, 1874, with six instructors and 39 students. It has been ranked as among the best public universities in the United States by major institutional rankings, and is renowned for its engineering program.

Randy Wayne (biologist)
Randy O. Wayne is an associate professor of plant biology at Cornell University. Along with his former colleague Peter K. Hepler, Wayne established the role of calcium in regulating plant growth. Their 1985 article ''Calcium and Plant Development'' was awarded the "Citation Classic" award from ''Current Contents'' magazine. They researched how plant cells sense gravity through pressure, the water permeability of plant membranes, light microscopy, as well as the effects of calcium on plant development. Wayne authored two textbooks, including ''Plant Cell Biology: From Astronomy to Zoology'' and ''Light and Video Microscopy''. Attempting to explain photosynthesis and gravitropism, Wayne has developed and promoted a fringe theory of light and gravity based on a concept of "binary photons". This concept is inconsistent with relativity and modern physics as a whole. Education Wayne completed his undergraduate studies in Botany at the University of Massachusetts. He earned an M. ...

Land Ethic
A land ethic is a philosophy or theoretical framework about how, ethically, humans should regard the land. The term was coined by Aldo Leopold (1887–1948) in his ''A Sand County Almanac'' (1949), a classic text of the environmental movement. There he argues that there is a critical need for a "new ethic", an "ethic dealing with human's relation to land and to the animals and plants which grow upon it".Leopold, A. 1949. ''A Sand County Almanac''. pp. 203. Oxford University Press, New York. Leopold offers an ecologically-based land ethic that rejects strictly human-centered views of the environment and focuses on the preservation of healthy, self-renewing ecosystems. ''A Sand County Almanac'' was the first systematic presentation of a holistic or ecocentric approach to the environment. Although Leopold is credited with coining the term "land ethic", there are many philosophical theories that speak to how humans should treat the land. Some of the most prominent land ethics include t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
