in this research, different concentrations of xanthan and lepidium perfoliatum seed gums (0.1, 0.2 and 0.3%) were used to improve the quality and shelf-life of chiffon cake. for this purpose, specific gravity and apparent viscosity of batter, and the volume, specific volume, moisture, sensory and texture properties, crumb and crust color were examined. to investigate the effect of gums on the s...

When interactive real-time applications are developed with very large volume data, the use of lossy compression is often inevitable. Lossy compression schemes generally encode data without consideration of the purpose of visualization that is actually performed, which often results in inefficient compression. In this paper, we present a new method for classifying voxels according to their impor...

The specific volume of dry protein is of interest in the interpretation of electron micrographs of protein molecules. A pycnometer with helium gas as the fluid is described and measurements on dry powders of lysozyme, ovalbumin, bovine serum albumin, and fibrinogen are reported. The values obtained exceed those from determinations on solutions by an average of 1.4 per cent when the latter measu...

Thermoplastic starch (TPS)/wood composites were prepared from starch plasticized with 36 wt% glycerol. The components were homogenized by dry-blending, extruded and injection molded to tensile bars. Tensile properties, structure, deformation, water adsorption and shrinkage were determined as a function of wood content, which changed between 0 and 40 vol% in 7 steps. The modification of TPS with...
