The primary spermatocytes of Drosophila virilis have been shown to undergo an approximate 300-fold increase in volume and to possess an abundance of ribo somes in the cytoplasm (Ito 1960). These ribosomes are probably involved in the biosynthesis of the various materials needed for this tremendous volumetric increase. Olivieri and Olivieri (1965) have demonstrated that RNA synthesis occurs in s...

the biological, biochemical and immunological It has been proved lately that lysosomes are conditions that prepare the organic susceptibility involved in the mechanism of morphologic which facilitates or impairs the growth of changes, catabolic disorders , autolytic pro­ M. leprae. This paper is a partial attempt to cesses, necrosis , and infections and inflammatory unveil the pathogenic mechan...

This report summarizes some useful data on the transport characteristics of gas mixtures which are required for detection of charged particles in gas detectors. The requirements for high luminosity tracking are stringent and different at low and high momenta, representing a compromise between a fast gas mixture, small diffusion properties and having a small Lorentz angle, but high primary ioniz...

Within the framework of the theory of interacting classical and quantum gases it is shown that the atomistic constitution of gases can be understood as a consequence of (second) quantization of a continuum theory of gases. In this note this is explained in some detail for the theory of non-relativistic interacting Bose gases, which can be viewed as the second quantization of a continuum theory ...

In case of typical chemical gas sensors reacted by gas adsorption on surface of an active layer, it is difficult to detect some gases which have low chemical adsorption energy like inert gases. In this paper, we report a gas sensor using carbon nanotube(CNT) array as electron emitters for the purpose of detecting these gases. Specifically, sensors were fabricated with applications of glass patt...

In this study, some characteristics of a Mather type Plasma Focus (PF) device such as a discharge current, pinch time, ion flux and hard x-ray intensity has been investigated simultaneously in argon and nitrogen gases separately for various operating gas pressures and charging voltages of capacitor bank. It was observed that pinch phenomena was energy and pressure dependent in current sheath as...

Despite 180 years of theory on magnetism, it appears that the practice of calculating forces on magnetic media is ambiguous, as illustrated by a recent article by Casperson [1]. Potentially troubling issues include: Which field B or H should be used? Should the total field be used, or only the external field? And if the latter, what is meant by “external”? Can/should effects of magnetization cu...

Biotrickling filters (BTFs) are becoming very potential means to purify waste gases containing multiple VOC components, but the removal of the waste gases by BTF has been a major challenge due to the extremely complicated interactions among the components. Four biotrickling filters packed with polyurethane foam were employed to identify the interactions among four aromatic compounds (benzene, t...
