In this study, two natural waxes, beeswax (BW) and sunflower wax (SFW), are combined with their hydrolyzed variants to deliberately alter the waxes’ composition. The properties of produced oleogels different inclusion levels (4%, 8%, 12%, 16% w/w) investigated after defined intervals (2 days, 7 3 weeks, months). To do so, gels monitored via penetrometry, microscopy, calorimetry. Although not sh...

STATEMENT OF PROBLEM Situations may arise in dental laboratories that could result in a time lapse between preparing the wax pattern of the removable partial denture framework and its casting into the cobalt-chromium alloy. PURPOSE This study investigated the effect of storage time of the wax pattern before casting and the influence of the palatal major connector design on the accuracy of its...

pomegranate is native to subtropical regions of iran. losses of horticultural products are a major problem in the postharvest chain. in this experiment, six different wrapping (polyethylene and paper covering), chemical (calcium chloride and wax) and thermal (4 °c and outdoor) treatments were applied on the fruits of pomegranate cv shirin kolbad and some physicochemical properties were measured...

This report contains the results of attempting to improve on the results of Scott R. Sawyer and Alan M. L’Esperance research paper “Investigation of Paraffin Wax as an Energy Storage Medium Within a Shell-and-Tube Heat Exchanger.” The overall goal of the paper mentioned was to investigate the usefulness of wax as an energy storage medium. Scott R. Sawyer and Alan M. L’Esperance determined that ...

Marinobacter hydrocarbonoclasticus DSM 8798 has been reported to synthesize isoprenoid wax ester storage compounds when grown on phytol as the sole carbon source under limiting nitrogen and/or phosphorous conditions. We hypothesized that isoprenoid wax ester synthesis involves (i) activation of an isoprenoid fatty acid by a coenzyme A (CoA) synthetase and (ii) ester bond formation between an is...

succinate contained increasing amounts of wax as the specific growth rate decreased from 0.7h-I to 0.12h-I. The wax composition also varied with dilution rate, samples having a high wax content had palmitic acid and palmityl alcohol as major components. In continuous culture with succinate limitation and excess of nitrogen, the bacteria contained only small amounts of waxes, which increased sli...

The capacity of developing countries for citrus fruits exportation is limited by the lack of adequate storage techniques. In studying this problem citrus sinensis Osbeck was treated with, a locally developed bemul-wax, calcium chloride dip, and a combination of the two. The treated fruits were assessed during four month low temperature storage (7.0 ± 3.0 o C; 9094% RH.) for their biochemical an...

most consumers prefer natural coatings to the chemical ones to act as an enhancement of storage quality of fruits. in this research, quality of thomson oranges coated with chitosan-clay nano composite edible coating plus fungicide-wax chemical coating was compared with a non-coated sample during storage for a period of 3 months through a factorial design (3×4). orange samples were kept in a col...
