Of Man And Manta
Of Man and Manta is a trilogy of science fiction novels written by Piers Anthony. It consists of the three books: ''Omnivore'' (1968), ''Orn'' (1970), and ' (1975). ''Omnivore'' has as its frame the investigation of the deaths of eighteen travelers from Earth to the distant planet Nacre. Nacre is seen through the eyes of three surviving scientist-explorers: Cal, Veg, and Aquilon. The planet Nacre's dominant species are fungi, including the intelligent ''mantas''. The mantas are soft-bodied creatures capable of high speeds and flight, superficially resembling manta rays. They are carnivores who farm the one extant herbivore species by protecting them from the voracious omnivore species. The planet is notable for its thick atmosphere, which allows flight to be performed with less energy, and permits the existence of air-borne phytoplankton. The herbivores eat the plankton, and the omnivores eat anything they can. The human characters' diets play an important role in their intera ...

Offshoring Research Network
The Offshoring Research Network is an international network of researchers and practitioners studying organizations in their transition to globalizing their business functions, processes and administrative services. The ORN conducts annual surveys tracking global sourcing strategies, drivers, concrete implementations and plans across all business functions and processes. The ORN is managed by Duke University, The Fuqua School of Business, Center for International Business Education and Research (CIBER). Offshoring, according to the ORN, refers to the process of sourcing business functions or processes supporting home-based or global operations from a foreign country, either through wholly owned organizational units (captive offshoring/ shared services) or external service providers (offshore outsourcing). History and current objectives The ORN project was launched in 2004 by the Center for International Business Education and Research (CIBER) at Duke University, The Fuqua S ...

Olfactory Receptor Neuron
An olfactory receptor neuron (ORN), also called an olfactory sensory neuron (OSN), is a sensory neuron within the olfactory system. Structure Humans have between 10 and 20 million olfactory receptor neurons (ORNs). In vertebrates, ORNs are bipolar neurons with dendrites facing the external surface of the cribriform plate with axons that pass through the cribriform foramina with terminal end at olfactory bulbs. The ORNs are located in the olfactory epithelium in the nasal cavity. The cell bodies of the ORNs are distributed among all three of the stratified layers of the olfactory epithelium. Many tiny hair-like non-motile cilia protrude from the olfactory receptor cell's dendrites. The dendrites extend to the olfactory epithelial surface and each ends in a dendritic knob from which around 20 to 35 cilia protrude. The cilia have a length of up to 100 micrometres and with the cilia from other dendrites form a meshwork in the olfactory mucus. The surface of the cilia is cover ...

Olympic Route Network
An Olympic route network (ORN) and Paralympic route network (PRN) is a network of dedicated roads linking venues and other key sites in a host city during Olympic and Paralympic games to ensure that athletes and officials get to events on time. Roads that are part of the network have 'games lanes' which are reserved for accredited games vehicles and on-call emergency vehicles. For the 2012 Olympic and Paralympic Games, a route network came into effect under the London Olympic Games and Paralympic Games Act 2006 which gave the Olympic Delivery Authority temporary powers to take over traffic management measures during London 2012. The ORN and PRN were first introduced for the 2000 Sydney Olympics as a result of problems at the Atlanta Olympics The 1996 Summer Olympics (officially the Games of the XXVI Olympiad, also known as Atlanta 1996 and commonly referred to as the Centennial Olympic Games) were an international multi-sport event held from July 19 to August 4, 1996, in ...

Oran Es Sénia Airport
Ahmed Ben Bella Airport ( ar, مطار أحمد بن بلة), formally Es-Sénia Airport is an airport located 4.7 nm (8.7 km) south of Oran (near Es Sénia), in Algeria. History During World War II, La Sénia Airport was first used by the French Air Force as a military airfield, first by the Armée de l'Air, and after June 1940, by the Armistice Air Force (french: link=no, Armée de l'Air de Vichy) of the Vichy government. During the Operation Torch landings in 1942, La Sénia was one of the primary objectives of the assault on Oran on 9 November. A paratroop task force was to be directly seize La Sénia, with an armored task force to thrust inland to insure the capture of the field. Just after daylight, eight Albacore dive bombers from H.M.S. ''Furious'' and six Hurricane fighter escorts from each of the two auxiliary carriers swung back over La Sénia airfield in broad daylight to be greeted by strong antiaircraft fire and Vichy fighters. The airfield was attacked in r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithine
Ornithine is a non-proteinogenic amino acid that plays a role in the urea cycle. Ornithine is abnormally accumulated in the body in ornithine transcarbamylase deficiency. The radical is ornithyl. Role in urea cycle L-Ornithine is one of the products of the action of the enzyme arginase on L-arginine, creating urea. Therefore, ornithine is a central part of the urea cycle, which allows for the disposal of excess nitrogen. Ornithine is recycled and, in a manner, is a catalyst. First, ammonia is converted into carbamoyl phosphate (). Ornithine is converted into a urea derivative at the δ (terminal) nitrogen by carbamoyl phosphate synthetase. Another nitrogen is added from aspartate, producing the denitrogenated fumarate, and the resulting arginine (a guanidinium compound) is hydrolysed back to ornithine, producing urea. The nitrogens of urea come from the ammonia and aspartate, and the nitrogen in ornithine remains intact. Ornithine is not an amino acid coded for by DNA, that is, ...

Osteoradionecrosis
Osteoradionecrosis (ORN) is a serious complication of radiation therapy in cancer treatment where radiated bone becomes necrotic and exposed. ORN occurs most commonly in the mouth during the treatment of head and neck cancer, and can arise over 5 years after radiation. Common signs and symptoms include pain, difficulty chewing, trismus, mouth-to-skin fistulas and non-healing ulcers. The pathophysiology of ORN is fairly complex and involves drastic changes to bone tissue as a result of DNA damage and cell death caused by radiation treatment. Radiation therapy targeting tumor cells can affect normal cells as well, which can result in the death of bone tissue. Advances in radiation therapy have decreased the incidence of ORN, estimated at around 2%. Certain risk factors including the size and location of tumor, history of smoking or diabetes, and presence of dental disease can affect the chances of developing ORN. Osteoradionecrosis is difficult to prevent and treat. Current preventio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
