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...
Study on heat and moisture vapour transmission characteristics through multilayered fabric ensembles
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...
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...
olyester and vinyl ester resinbased linings are known for their solvent and chemical resistance. The different resins in these linings have broad resistance ranges, with acid resistance being a major strength. Some of the specific resins resist 1 or more chemicals or types of chemicals better than other resins, so systems often are finetuned by the choice of resin for a particular chemical envi...
Current work presents the first investigation on Mode II fracture toughness of room temperature curable acrylic Elium® resin and toughened Elium®IM with 10% weight acrylonitrile butadiene styrene (ABS) particle different thermoplastic fabrics like Ultra-high molecular polyethylene (UHMWPE), polypropylene (UHMWPP), polyester. The testing methodology using doublers, performance under loading unde...
The cell biological mechanism controlling the regeneration of renal tubules in renal failure after application of stem/progenitor cells is subject of actual research. Unsolved issues are the integration of stem/progenitor cells in a diseased organ environment, the differentiation into epithelial tissue and the formation of tubules in a spatial environment. Following this therapeutic strategy ne...
