The issue of the equivalence physical parameters working medium in heat-treatment zone fish and meat products is solved by organizing uniform high-speed fields area, which ensured corresponding design. aerodynamic characteristics a double-sided centrifugal blower fan with vertical arrangement drive shaft spiral scroll two outlet openings, outlines were carried out according to design square rul...

Psoriasis is a chronic, relapsing, cutaneous condition with a I%-2% prevalence in thegeneral population. About 40% of psoriafics report that psychosocial stress significantly exacerbates their condition. However, the clinical characferistics of the subgroup of psoriatic patients who are stress reactors have not been delineated. At a practical clinical level if is fherefore difficult to implemen...

n this paper, a mathematical model has been derived to predict the granulation time of anaerobic sludge in UASB reactors. In the proposed model, some physical, chemical and biological parameters affecting the granulation phenomena have been considered. To validate the model, 12 pilot-scale experiments in 4 UASB reactors are carried out and the results are discussed here. The reactors are starte...

Factors contributing to the proliferation resistance of CANDU reactors are examined, from the point of view of both intrinsic design features (related primarily to fuel cycle details and operational requirements), and extrinsic measures (primarily IAEA safeguards). It is shown how the technical features of CANDU reactors and fuel cycle, in most cases derived from the fundamental physics of heav...

BACKGROUND During strategic planning of a biogas plant, the local availability of resources for start-up and operation should be taken into consideration for a cost-efficient process. Because most bioethanol/sugar industries in Brazil are located in remote areas, the use of fresh cattle manure from local farms could be a solution for the inoculation of the biogas process. This study investigate...

Abstract: In this paper, we investigate the non-cooperative reaction-diffusion model of nuclear reactors subject to the homogeneous Neumann boundary condition. By establishing appropriate Lyapunov functions, we prove the global stability of the unique positive constant equilibrium solution.

Background: Persistent thyroglossal duct leads to a fibrous cyst formation named thyroglossal cyst which is the most common form of congenital cyst and usually located in the midline neck below the hyoid bone. Rarely the thyroglossal cyst is associated with thyroid cancer. Although the Sistrunk procedure is often considered adequate, currently there is no clear consensus on the optimal manageme...

A 63-year-old man presented with painless jaundice, loss of appetite and significant weight loss. Cross-sectional imaging showed a diffusely enlarged pancreas, with no significant fat stranding and a hypodense rim on computed tomography, which appeared hypointense on T2-weighted magnetic resonance imaging. There was a narrowed pancreatic duct and features of common bile duct narrowing in the re...

Inertial migration of neutrally buoyant particles in a square duct has been investigated by numerical simulation in the range of Reynolds numbers from 100 to 1000. Particles migrate to one of a small number of equilibrium positions in the cross-sectional plane, located near a corner or at the center of an edge. In dilute suspensions, trains of particles are formed along the axis of the flow, ne...

introduction extra-hepatic bile duct injuries in children following blunt abdominal trauma are rare; early diagnosis and treatment are imperative for a good outcome. the purpose of this report is to describe the management of problems encountered in children with bile duct injuries following blunt abdominal trauma. case presentation a three year-old girl presented with obstructive jaundice and ...
