The relevance of the study is due to fact that loading granulated polymer material into working hopper extruders mainly carried out manually from bags by production operators. capacity hoppers limited with a significant height bulk material, an increase in static pressure occurs lower layers, which leads formation vaults, uneven supply cylinder and deterioration quality products. Since work pro...

The paper considers the problem of nding points of maximum loadability which are closest (in a local sense) to the power system operating point. This optimization problem leads to a set of equations which describe such critical points. Not all solutions of this set of equations are critical points. The paper therefore explores the nature and characteristics of solutions. A two stage algorithm i...

Cohesin is a conserved ring-shaped multiprotein complex that participates in chromosome segregation, DNA repair, and transcriptional regulation [1, 2]. Cohesin loading onto chromosomes universally requires the Scc2/4 "loader" complex (also called NippedBL/Mau2), mutations in which cause the developmental disorder Cornelia de Lange syndrome in humans [1-9]. Cohesin is most concentrated in the pe...

Abstract Object of research is build-up compressed–bent and eccentrically compressed columns on yielding nonlinear – deformable shear bracings. Purpose the development a numerical method for calculation columns, allowing to take in account influence deflection elastic axis bar increment bending moment from action longitudinal compressive force dependence between forces deformations Problem-solv...

The proximal duodenal mucosa, exposed to frequent pulses of gastric acid, is functionally "leaky", increasing the importance of defense mechanisms such as the mucus gel layer, cellular acid/base transporters, bicarbonate secretion, and mucosal blood flow. Our laboratory has used a unique in vitro perfused microscopic system to measure thickness of the adherent mucus gel (MGT), intracellular pH ...

1 Ouabain was administered at a loading dose of 3 jg/kg followed by an infusion at a rate of 1 jig kg-1 min-' in order to produce severe dysrhythmia in dogs within 60 minutes. Similarly, digitoxin at a loading dose of 9 jg/kg followed by an infusion at a rate of 3 ,ug kg-' min-' was administered to compare its effect with that of ouabain. 2 During the 60 min experimental period, the plasma conc...

PURPOSE The purpose of this study was to evaluate various core designs on stress distribution within zirconia crowns. MATERIALS AND METHODS Three-dimensional finite element models, representing mandibular molars, comprising a prepared tooth, cement layer, zirconia core, and veneer porcelain were designed by computer software. The shoulder (1 mm in width) variations in core were incremental in...
