the rheological behavior of feedstocks used in powder injection molding technology influences strongly on the final properties of the products. powder loading is one of the important factors that have a great distribution on rheological behaviors. by using the gas atomized spherical 316l stainless steel powder and the binder of 55% paraffin wax+ 40% polyethylen+ 5% stearic acid, four kinds of f...

Cuticular wax deposition and composition affects drought tolerance and yield in plants. We examined the relationship between wax and dehydration stress by characterizing the leaf cuticular wax of tree tobacco (Nicotiana glauca L. Graham) grown under periodic dehydration stress. Total leaf cuticular wax load increased after each of three periods of dehydration stress using a CH2Cl2 extraction pr...

‘Golden Delicious’ apples (Malus domestica Borkh) were pressure-infiltrated at harvest with a 4% CaCl2 solution either without prior heat treatment or following 4 days at 38C. Examination of the apple surfaces from both treatments by low-temperature scanning electron microscopy revealed that heat treatment changed the pattern of epicuticular wax. The epicuticular wax of nonheated fruit exhibite...

Abstract Values of energy supply and demand vary within the same timeframe are not equal. Consequently, to minimise amount wasted, there is a need use various types storing systems. Recently, one can observe trend in which phase change materials (PCM) have gained popularity as that store an excess heat energy. In this research, authors analysed paraffin wax (cheese wax)’s capability PCM materia...

The aim of this study was to investigate the release characteristics of matrix (non-disintegrating) granules consisting of diltiazem hydrochloride (model drug) and glyceryl behenate (a wax matrix forming polymer) for sustained release application using sintering technique. The granules of diltiazem hydrochloride-wax matrix were prepared by melt granulation technique. This was formed by triturat...

OBJECTIVES To investigate whether the wax moth larva, Galleria mellonella, is a suitable host for assessing the in vivo efficacy of antistaphylococcal agents against Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) infections. METHODS Wax moth larvae were infected with increasing doses of S. aureus to investigate the effect of inoculum size on larval survival. In addition, inf...

Wax monoesters are synthesized by the esterification of fatty alcohols and fatty acids. A mammalian enzyme that catalyzes this reaction has not been isolated. We used expression cloning to identify cDNAs encoding a wax synthase in the mouse preputial gland. The wax synthase gene is located on the X chromosome and encodes a member of the acyltransferase family of enzymes that synthesize neutral ...

models were poured by using type 3 dental stone (Giludur, BK Giulini). Thereafter, wax patterns of epitheses (Figure 2) were prepared by using dental wax (Cavex Set Up Wax, Cavex) based on cast models and photographs of healthy ears. After the trial of wax patterns on patients in terms of marginal fit and anatomical localization, cast models were molded (Figure 3). The molds were then placed in...

Cuticular waxes act as a protective barrier against environmental stresses. In the present study, we investigated developmental and genotypic variation in wax formation of cabbage lines, with a view to understand the related morphology, genetics and biochemistry. Our studies revealed that the relative expression levels of wax biosynthetic genes in the first-formed leaf of the highest-wax line r...
