The influences of several operating factors on the viscosity of the Isfahan refinery waxy crude oil sample are studied through conducting some rheological shear rotational tests. The Taguchi design method is adopted to determine the impact of factors such as shear rate, temperature, cooling rate, wax content, and asphaltene content on the viscosity of the waxy crude oil. The results show that t...

the dried aerial parts of scutellaria lateriflora l. (family labiatae), have been used for many years as a domestic remedy for epilepsy, hysteria, and nervous tension states. although several phytochemical investigations have been made regarding the constituents present in this species (i. e. flavonoids, iridoids), none has been recorded concerning the cuticular wax. using thin-layer chromatogr...

BACKGROUND Wax gourd is a widely used vegetable of Cucuribtaceae, and also has important medicinal and health values. However, the genomic resources of wax gourd were scarcity, and only a few nucleotide sequences could be obtained in public databases. METHODOLOGY/PRINCIPAL FINDINGS In this study, we examined transcriptome in wax gourd. More than 44 million of high quality reads were generated...

STATEMENT OF PROBLEM Metal-ceramic crowns are most commonly used as the complete coverage restorations in clinical daily use. Disadvantages of conventional hand-made wax-patterns introduce some alternative ways by means of CAD/CAM technologies. PURPOSE This study compares the marginal and internal fit of copings cast from CAD/CAM and conventional fabricated wax-patterns. MATERIALS AND METHO...

The aim of this study was to use a detailed rheological characterization to gain new insights into the gelation behavior of natural waxes. To make a comprehensive case, six natural waxes (differing in the relative proportion of chemical components: hydrocarbons, fatty alcohols, fatty acids, and wax esters) were selected as organogelators to gel high-oleic sunflower oil. Flow and dynamic rheolog...

Wax-based additives have been widely used in asphalt pavement for their preferable environmental benefits. However, poor compatibility between wax-based warm mix and easily leads to precipitation of wax cracking pavement. Plasma treatment can effectively modify the surface various materials. This study applies plasma improve properties improvement binder. Compatibility two different wax-base bi...
