Microwave absorbing materials are usually designed to solve protection against electromagnetic interference in wireless communication systems and high frequency circuit mechanisms. In this research polystyrene (PS) nanocomposites containing various nano-fillers were successfully synthesized. The novelty of this work is comparing of three various nanostructures: non-metallic conductive graphene ...

There are two common methods for preparing animal tissues for oxygen uptake studies; namely, the “slice technique” and the “mince technique.” In the former method the tissues are cut into thin slices about 0.3 mm. thick, care being taken to damage the tissues as little as possible. In the latter method no precautions are taken to avoid damage to the tissues, which are either run through a mecha...

The number of mitochondria per cell varies substantially from cell line to cell line. For example, human HeLa cells contain at least twice as many mitochondria as smaller mouse L cells. This protocol starts with a washed cell pellet of 1-2 mL derived from ∼10⁹ cells grown in culture. The cells are swollen in a hypotonic buffer and ruptured with a Dounce or Potter-Elvehjem homogenizer using a ti...

For planar laser diagnostics, a most uniform beam profile is highly desirable for two reasons: first, subsequent corrections for an inhomogeneous intensity distribution are time consuming and prevent on-line engineering assessment and second, temporal fluctuations cannot be corrected anyway. However, in general for combustion and flow diagnostics pulsed laser sources are used to achieve a high ...

The priority task of the milk processing industry is in reducing specific energy consumption fat dispersion while simultaneously ensuring a high emulsion. One possible ways to solve this problem by developing and implementing little-studied jet homogenizer slot type. In it, homogenization occurs method separate feeding cream, which allows creating maximum difference between speeds skim necessar...
