Caring for Pressurized Tissues

زخم های فشاری، یکی از عوارض ناخواسته درمانی بوده و اکثراً با درک هوشیاری و مراقبت بموقع قابل پیشگیری است. امروزه زخم های فشاری یا زخم بستر یکی از مسائل بغرنج درمانی محسوب می شود و این مسئله تا حد زیادی مربوط به این واقعیت است که، تعداد بسیاری از بیماران سالخورده از بیماری های جدی و حاد جان سالم بدر برده ولی به علت سالخوردگی و پاتولوژی عوامل چندگانه بیشتر در معرض ابتلاء به زخم های بستر می باشند.

Continuous flow separations in microfluidic devices.

Biochemical sample mixtures are commonly separated in batch processes, such as filtration, centrifugation, chromatography or electrophoresis. In recent years, however, many research groups have demonstrated continuous flow separation methods in microfluidic devices. Such separation methods are characterised by continuous injection, real-time monitoring, as well as continuous collection, which m...

A Supercritical Fluid Chromatograph for Physicochemical Studies

A supercritical fluid chromatograph has been designed and constructed to make physicochemical measurements, while retaining the capability to perform chemical analysis. The physicochemical measurements include diffusion coefficients, capacity ratios, partition coefficients, partial molar volumes, virial coefficients, solubilities, and molecular weight distributions of polymers. In this paper, t...

Pressurized Structure Technology for Uavs

There is a critical need to improve the performance and utility of unmanned aerial vehicles (UAVs). Several areas of UAV performance need to be improved for the next generation of UAVS to be used successfully in expanded future combat roles. For example current time aloft is only on the order of an hour or two for electric-powered UAVs. The current generation of UAVs lacks vertical takeoff and ...
