To detect Streptococcus pneumoniae colonization, the nasopharynx is sampled using a swab placed in skim milk-tryptone-glucose-glycerol (STGG) transport medium, and then the swab specimen or STGG medium is cultured or subjected to PCR. We evaluated the effect of swab composition and compared the sensitivities of detection of culture and PCR using swabs and swab-containing medium. Calcium alginat...

A flexible azobenzene side-chain liquid crystalline (SCLC) polyester architecture employed for reversible optical storage is described. The modular design allows four structural parameters to be individually modified. These parameters: ithe methylene side-chain spacer length, iithe substituent on azobenzene, iiithe methylene main-chain segment length, and ivthe polyester molecular mass, all inf...

BACKGROUND The operative control of noncompressible hemorrhage is the single largest impact that could be addressed in reducing the mortality on the battlefield. Laprotomy pads, traditionally used for hemorrhage evacuation, are made of woven cotton, and, while effective, their use requires a substantial amount of space and adds weight. This poses no concern in traditional operating rooms but is...

The present paper reports a detailed study on heat and moisture vapour transmission characteristics of different types of multilayered fabric ensembles. Two sets of multilayered fabrics have been prepared. In first set, two types of carded web produced from acrylic and polyester fibres with five different areal densities in each fibre type have been used as middle layer. In second set, differen...

introduction: conventional technology of sugar production from sugar beet roots consists of the next subsequent steps: sugar beet slicing, thermal denaturation of the sliced beet roots followed by diffusion in hot water at 70–75 _c, purification of extracted juice by lime, concentration of purified juice and crystallization. the diffusion process is one of the most important steps that effect o...

In this study, 2 types of polymers were mixed, namely polyester and vinylester called polyester-vinylester blend (PVB) as the test workpiece. The experiments carried out testing surface quality hole, roughness (R a ), hardness alteration (SHA) after drilling. effects spindle speed ( n ) & feedrate f cutting-edge angle K r PVB composition P%V% tested. results showed that factor most influenc...

Alkaline pre-extraction and hydrothermal hydrolysis were carried out with eucalyptus chips. Two methods were used to determine and calculate the extraction yield of five-carbon sugars. One is an indirect method, based on the difference of pentosan content between the chips before and after pre-extraction. The other method is to directly measure the content of five-carbon sugars in the extractin...
