Aim of study: This study aimed to improve some physical, mechanical properties, and fire resistance wood-plastic composites (WPCs) with short glass fiber reinforcement (SGFR). Materials Methods: The WPCs were reinforced different ratios (SGF). effect on the water absorption (WA), thickness swelling (TS) as physical flexural strength, modulus elasticity, tensile strength properties determined. p...

This paper describes an efficient 3-D positioning method of SAR image only using ephemeris data and a single control point. The proposed method is applied to RADARSAT-1 SGF images of which ephemeris information is not accurate enough to directly use for the dynamic geometric modeling. The RMSE of the 3-D model by using a single CP (Control Point) is 43.86m, while that of traditional method usin...

From two corpus studies into varieties of clausal coordination in English (Meyer, 1995 and Greenbaum & Nelson, 1999), it is known that the incidence of clausal coordinate ellipsis (CCE) is about two times higher in written than in spoken language. We present a treebank study into CCE in written and spoken Dutch and German which confirms this tendency. Moreover, we observe considerable differenc...

The present paper describes development of a polysaccharide based compression coated tablets of secnidazole for colon delivery. Core tablet containing secnidazole was compression coated with various proportions of guar gum, xanthan gum and chitosan, either alone or in combinations. Drug release studies were performed in simulated gastric fluid (SGF) for 2 h followed by simulated intestinal flui...

Objective(s): In a new approach, following the development in metal oxide chemistry, the ibuprofen as low water soluble nonsteroidal anti-inflammatory drug diffused into synthetic sol-gel derived nano porous g-alumina by an impregnation method in order to increase the solubility and control the drug release in physiological environment. Methods: Sol-gel m...

Lecture notes written in the spirit of Feynman lectures on quantum mechanics. Feynman extensively uses Stern-Gerlach filters to describe basic principles of QM using thought experiments with polarized electron beams. We add the discussion on the EPR paradox, hidden parameters and Bell inequalities. This is not meant as an introductory text from quantum mechanics. It is rather a supplement to be...

Multiple-unit-type oral floating hollow microspheres of 5-fluorouracil (5-Fu) were developed using modified solvent evaporation technique to prolong gastric residence time, to target stomach cancer, and to increase drug bioavailability. The prepared microspheres were characterized for micromeritic properties, floating behavior, entrapment efficiency, and scanning electron microscopy (SEM). The ...

The xanthan/chondroitin sulfate (X/CS) hydrogels, obtained by a crosslinking technique, were evaluated in vitro and in vivo as matrices for theophylline release. The influence of pH of simulated physiological media on the X/CS swelling behaviour at 37 ̊C was investigated. The hydrogels theophylline loading degree was evaluated by near infrared chemical imaging (NIR-CI) technique and confirmed al...
