in this study, the effects of strength and direction of the magnetic field on lid-driven cavity flow in the whole range of magnetic field strength variations, which already used in practice up to present (0 to 10 tesla), are studied. the governing equations, including conservative equations of momentum, continuity and magnetic field equations were solved numerically. momentum and continuity equ...

background: hydatidosis it is a zoonotic disease which is caused by the larval stages of different species of the tapeworms (cestoda) of genus echinococcus. currently, the surgery is most definitive method of treatment for hydatid cyst, but always there is the risk of leakage or rupture during the surgery, therefore it is considered unreliable method. methods: protoscoleces of hydatid cysts wer...

Static and alternating magnetic field effects are introduced from the viewpoint of radical-radical interaction. Since the effect of magnetic field is much smaller than that of the electric field, the magnetic field dependence is a very sensitive measurement of the interaction between radicals. The low-field peak on the magnetic field effects and the spin-correlated radical pair polarization of ...

polyhydroxyalkanoates (phas) are naturally occurring polyester that can be accumulated in bacterial cells as a carbon and energy storage compound. they are metabolized by many microorganisms. these biopolymers accumulate in microbial cells under stress conditions such as limitation of nitrogen, phosphate, sulfur, oxygen, and excess carbon source. currently, phas have attracted increasing intere...

Semiconductor Research Corporation under contract no 2008-KJ-1871 Abstract—The magnetic field in an electron cyclotron resonance plasma processing system was characterized using IEEE standard measurement practices. We discuss methods for a low-cost Hall-effect sensor array construction, calibration, and measurement collection to meet or exceed available standards. Utilizing standard measurement...

During the last years improvements in magnetic field measurement technology of conventional, i.e. permanent magnet based insertion devices (IDs), made significant progress and pushed the capabilities of synchrotron light sources. For superconducting IDs similar developments are now needed to perform precise measurements of local magnetic fields and field integrals. We follow this aim within our...

In this work, structural and magnetic properties of LaMnO3+δ compound prepared by citrate precursor method and annealed in presence of oxygen are investigated. The structural characterization of LaMnO3+δ by X-ray powder diffraction and using X’pert package and Fullprof program is evidence for a rhombohedral structure (R-3c space group) confirmed by FTIR measurement. The magnetic measurements sh...

1 Contribution of NIST, an agency of the US government; not subject to copyright in the United States Abstract Knowledge of the magnetic field is required to determine the quadratic Zeeman bias of a cesium frequency standard. The small magnetic fields (C-field) used in PARCS (PARCS is the primary atomic reference clock in space project), may have sufficient inhomogeneity that it is not practica...
