The article presents results of the development and research a hyperspectral imaging spectrometer for analyzing borehole fluids in real operating conditions spectral range from 0.35 microns to 2.1 microns. A mathematical model an algorithm identifying fluid by composition percentage content based on image analysis are developed.

micro-electro-mechanical systems (mems) are combination of electrical and mechanical components in micron dimensions. in recent years, holding, actuating methods and handling of mems components such asmicrogripper, microsensors and etc. have been deeply studied. microgrippers for handling, positioning andassembling of micro components are very useful so that for clamping need actuation created ...

BACKGROUND The optimal particle size of a beta 2 agonist or anticholinergic aerosol in patients with severe airflow obstruction is unknown. METHODS Seven stable patients with a mean forced expiratory volume in one second (FEV1) of 37.9% of the predicted value inhaled three types of monodisperse salbutamol and ipratropium bromide aerosols with particle sizes of 1.5 microns, 2.8 microns, and 5 ...

The mechanism for the preferential distribution of emboli to cerebral arterial borderzone regions, known to cause some watershed infarcts was studied. We hypothesized that emboli of a specific size range are selectively directed to the arterial borderzones due to the tendency of emboli to bypass the small arterial branches which emerge proximal to major borderzones. To test this hypothesis we p...
