One of the primary assumptions in most optimal pricing methods is that the production cost is a non-increasing function of lot-size. This assumption does not hold for many real-world applications since the cost of unit production may have non-increasing trend up to a certain level and then it starts to increase for many reasons such as an increase in wages, depreciation, etc. Moreover, the prod...

Methane is the second most important greenhouse gas (GHG) after carbon dioxide. Amount of methane emission from energy sector is increasing day by day with various activities. In present work, various sources of methane emission from upstream, middle stream and downstream of oil & gas sectors are identified and categorised as per IPCC-2006 guidelines. Data were collected from various oil & gas ...

The objectives of this study were to partition corn grain into three digestible fractions and to measure the rate of disappearance of these fractions in vitro. Seventeen corn grain samples with varied fiber concentrations were extracted with either 80% ethanol or neutral detergent to obtain estimates of the pool size and digestion kinetics of the A, B1, B2, and C fractions. The carbohydrate sol...

The purpose of this study was to investigate the effects of warm and cold physical as well as chemical processing methods on the nutritive value of barley grains by gas production technique. The processing methods included milling, steam flaking, extruding and soaking up the grain in water containing 1.00% citric acid, 1.00% propionic acid and 0.01 M sulfuric acid. Two-hundred mg of milling sam...

introduction energy is one of the most important commodities that make up a large proportion of international trade. among all the countries in the world, iran is known as semi-industrial developing country which is rich in energy such as non-renewable energy in particular fossil fuel. use of energy affects the environment in various forms of pollution. in the agricultural sector, the fao repor...

Fluxes through intrahepatic glucose–producing metabolic pathways were measured in normal humans during overnight or prolonged (60 h) fasting. The glucuronate probe was used to measure the turnover and sources of hepatic UDP-glucose; mass isotopomer distribution analysis from [213 C 1 ]glycerol for gluconeogenesis and UDP-gluconeogenesis; [U13 C 6 ]glucose for glucose production (GP) and the dir...

The Genetic Programming (GP)[1] is one of the novel evolutionary computation which is applied to complicated structure problems. The most important feature of GP is that individuals in GP are represented by the tree structure. The expression ability of tree structure is very flexible, and this is why GP is expected to solve many difficulties of Genetic Algorithms (GAs). However, the analysis of...

Fluxes through intrahepatic glucose-producing metabolic pathways were measured in normal humans during overnight or prolonged (60 h) fasting. The glucuronate probe was used to measure the turnover and sources of hepatic UDP-glucose; mass isotopomer distribution analysis from [2-13C1]glycerol for gluconeogenesis and UDP-gluconeogenesis; [U-13C6]glucose for glucose production (GP) and the direct ...

Due to its excellent effect of surface subsidence reduction, the overburden-separation grouting (OSG) technology has been widely applied green mining. However, OSG changes mine pressure, and resultant gas emission in stope remains unclear. Therefore, with 22301 working face Tunlan Coal Mine as an example, overburden deformation stress distribution absence presence were studied through numerical...

We consider a gas of fermions at zero temperature and low density, interacting via a microscopic two body potential which admits a bound state. The particles are confined to a domain with Dirichlet (i.e. zero) boundary conditions. Starting from the microscopic BCS theory, we derive an effective macroscopic Gross-Pitaevskii (GP) theory describing the condensate of fermion pairs. The GP theory al...
