The filamentary structure of a sunspot penumbra is believed to be magnetoconvective in origin. In the outer penumbra there is a difference in inclination of up to 30 Y40 between the magnetic fields associated with bright and dark filaments, and the latter fields plunge downward below the surface toward the edge of the spot.We have proposed that these fields are dragged downward bymagnetic pumpi...
Due to the necessity to achievement of heat pump manufacturing technology as an important step in the development of geothermal systems, a heat pump is designed, manufactured and analyzed in different operating conditions. The heat pump is water to water type which is extensively used for heating buildings in winter. A sample of a heat pump from a famous manufacturer is selected to dissemble an...
The magnetization dynamics in magnetic double layers is affected by spin-pump and spin-sink effects. So far, only the spin pumping and its effect on the magnetic damping has been studied. However, due to conservation of angular momentum this spin current also leads to magnetic excitation of the layer dissipating this angular momentum. In this Letter we use time resolved magneto-optic Kerr effec...
We discuss the aspects of axion-like-particles (ALPs) searches with Light-Shining-through-Wall (LSW) experimental setups consisted two radio-frequency cavities. compare efficiencies three which involve cavity pump modes and external magnetic fields. Additionally, we sensitivity dependence both on relative position cylindrical cavities their radius-to-length ratio.
BACKGROUND The diagnosis of peri-procedural myocardial infarction is complex, especially after the emergence of high-sensitivity markers of myocardial necrosis. METHODS In this study, patients with normal baseline cardiac biomarkers and formal indication for elective on-pump coronary bypass surgery were evaluated. Electrocardiograms, cardiac biomarkers, and cardiac magnetic resonance imaging ...
In this paper, a simulation-based method is proposed for optimal placement of vibration sensors for the purpose of fault detection in a centrifugal pump. The centrifugal pump is modeled to investigate the effect of vane tip fault on fluid flow patterns numerically. Pressure pulsations are investigated at different locations at the inner surface of the pump before and after the presence of the f...

Apexes of commercial pyramidal silicon scanning microscopy tips were magnetically functionalized by means of local focused electron beam induced deposition. High aspect ratio supertips and local tip coatings with varying apex diameters can be produced by varying exposure time, beam current, and scan mode. The carbonyl precursor Co2(CO)8 was used as source of magnetic metal. Tip performance was ...
background and objectives: pseudomonas aeruginosa (pa) is one of the most important causes of nosocomial infections and has an intrinsic resistance to many antibiotics. among all the resistance-nodulation-division (rnd) pumps of p. aeruginosa, mexab-oprm is the first efflux pump found to target multiple classes of antibiotics. this study was aimed to evaluate the expression level of genes expre...
