The Theory of Constraints (TOC) is a powerful new management philosophy that recognizes system constraints limit the performance of a system and proposes a set of concepts to manage the constraints. TOC management philosophy (i) suggests the goal of an organization is to make money without violating certain necessary conditions such as customer satisfaction and employee satisfaction and securit...

Hybrid composites have been drawing the attention of researchers in field because their high flexibility to tailor properties through fibers hybridization. The behavior hybrid is dependent on nature, amount, processing parameters, among other each reinforcing fiber and polymeric resin. glass fiber/vegetable reinforced polymer combine performance synthetic with ecological appeal vegetable ones. ...

Meloidogyne incognita race 1, M. javanica, M. arenaria race 1, M. hapla, and an undescribed Meloidogyne sp. were analyzed by comparing isozyme phenotypes of esterase, malate dehydrogenase, phosphoglucomutase, isocitrate dehydrogenase, and alpha-glycerophosphate dehydrogenase. Isozyme phenotypes were obtained from single mature females by isoelectric focusing electrophoresis. Of these five isozy...

We consider the focusing energy-critical nonlinear Schrödinger equation iut + ∆u = −|u| 4 d−2 u in dimensions d ≥ 5. We prove that if a maximal-lifespan solution u : I × Rd → C obeys supt∈I ‖∇u(t)‖2 < ‖∇W‖2, then it is global and scatters both forward and backward in time. Here W denotes the ground state, which is a stationary solution of the equation. In particular, if a solution has both ener...

Observation of the microcirculation of the hamster cheek pouch by intravital microscopy revealed five steps of neutrophil migration from the venules after topical application of leukotriene B(4) to the microvasculature: rolling along the venular wall (Step 1), adhesion to it (Step 2), disappearance from the vascular lumen (Step 3), presence between the endothelial cells and the subendothelial b...

soil compaction as a global problem and a multi-dimensional and complex process involving the interaction of climate, soil mashyn- plant- known to have a significant economic and environmental impacts and to sustainable agriculture is an intractable problem.for in order to assess compaction effect on nitrogen mineralization process in soil in form of factorial completely randomized design with ...

prostate-specific antigen (psa) was purified to homogeneity from human seminal plasma by ion-exchange chromatography on a cm-sephadex c-50 and by gel filtration on a sephacryl s-200 column. a single 33-kda protein band appeared in sds-page. high pressure liquid chromatography (hplc) of the purified protein produced a single peak, while isoelectric focusing demonstrated the presence of five diff...
