investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (lhr) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].the engine had different operating conditions...

The principle of conventional magnetic recording is that magnetic fields are applied parallel to the plane of the magnetic medium. As described in this paper, the invention and development of a new method of placing the magnetized information perpendicular to the plane of the magnetic recording medium is presented. The yield in the mass production of high-density hard disk drives (HDDs) for per...

Electrolyzed reduced water (ERW) has attracted much attention because of its therapeutic effects. In the present study, a new culture medium, which we designated Water medium, was developed to elucidate the effects of ERW on the lifespan of Caenorhabditis elegans. Wild-type C. elegans had a significantly shorter lifespan in Water medium than in conventional S medium. However, worms cultured in ...

Gonococcal infections can no longer be considered exclusively urogenital but it is difficult in a busy routine laboratory to identify gonococci from non-genital sites, especially if other commensal neisseria are present. Unfortunately, conventional serum agar sugars sometimes give equivocal results. A fermentation medium is described for the identification of gonoccoci. On preliminary testing t...

A biphasic culture medium suitable for cultivation and sporulation of Clostridium perfringens, C. botulinum, and C. sporogenes was devised. The medium designed for use in a disposable, compartmented, plastic film container contained peptones, yeast extract, minerals, an anion exchange resin, and glucose in 4% agar as the solid phase and (NH(4))(2)SO(4) and 0.1% agar as the liquid phase. With th...

A radiometric method to determine the MIC of ansamycin (LM427) for Mycobacterium avium complex clinical isolates has been developed. It is based on a comparison of the conventional growth curve determination and the radiometric detection of growth (growth index) in the same liquid medium (7H12 broth). This new method requires less time and labor than does a conventional determination of MIC in ...

Non-conventional architectures that enable optimizing the power consumption in a second-order or an equivalent second-order scheme are proposed. The solutions exploit the significant difference in power consumption of comparators and OTAs that makes it advantageous to use more comparators to replace an OTA. Moreover, the use of op-amp time-sharing is discussed. For this a conventional second or...

The species of Lactobacillus are widely present in many natural environments that areimportant in fermented processes. Among these species some belong to the lactic acid bacteria group that areuseful in fermented food. One of the species of lactobacilli group such as L. plantarum provides health benefits,but their identification is one of the main issue. In order to proceed with this project, c...

INTRODUCTION Agricultural producers are exposed to a number of different health risks associated with their work environment. AIM The objective of the study was to assess the degree of colonization by fungi in terms of quantity and in terms of variety of species the samples taken from the settled dust from combine threshing of rye cultivation from organic and conventional farms in the Provinc...

S. aureus ID (bioMérieux, La Balme Les Grottes, France) is a new chromogenic agar medium designed to enable the isolation of staphylococci and the specific identification of Staphylococcus aureus. S. aureus produces green colonies on this medium due to production of alpha-glucosidase. To evaluate this medium, a total of 350 wound swabs were cultured onto S. aureus ID, CHROMagar Staph. aureus, a...
