Background: In food industry, carotenoids are used as food colorants conferring yellow to red color. This research was designed to study on lipid and β-carotene production by Rhodosporidium diobovatum cultured with different Carbon to Nitrogen (C/N) ratios. Methods: R. diobovatum was cultured in a medium containing 40 g/l glucose (as the carbon source) and different C/N ratios (20, 50, and 80)...

De novo interpretation of tandem mass spectrometry (MS/MS) spectra provides sequences for searching protein databases when limited sequence information is present in the database. Our objective was to define a strategy for this type of homology-tolerant database search. Homology searches, using MS-Homology software, were conducted with 20, 10, or 5 of the most abundant peptides from 9 proteins,...

In a time when modern production has become exposed to strict market demands, in terms of increasing quality, shortening the processing time and reducing the cost of the final product, laser processing has become a necessity in almost all manufacturing industries. Each laser manufacturer, including the Swiss company Bystronic, gives recommended cutting parameters for certain types of materials....

correct estimation of water inflow into underground excavations can decrease safety risks and associated costs. researchers have proposed different methods to asses this value. it has been proved that water transmissivity of a rock joint is a function of factors, such as normal stress, joint roughness and its size and water pressure therefore, a laboratory setup was proposed to quantitatively m...

Today’s ultrasound imaging systems produce better images and display more information than it was possible to display 30 years ago. Similarly, performance criteria for ultrasound imaging systems and the tools used to make these measurements have evolved, and have become more complex. This presentation will informally discuss a few examples of the evolution of ultrasound imaging systems and perf...

27 Using projective and objective measures, effects of rock music on emotion were investigated. Sixty students were randomly assigned to three conditions: hard rock, soft rock, and no music. One group listened to hard rock music while taking a projective test with five ink blots and an objective test with an Emotional Assessment Scale (EAS). The same procedure was used for the second group whil...

Fractures play an important role in steam production from geothermal reservoirs. It has been a challenge for a long time to characterize materials with a high density of fractures such as The Geysers rock. Experimental data showed that the capillary pressure curves of The Geysers rock are very different from that of Berea sandstone. Methods to characterize the difference between the two have be...

In this article we investigate homological aspects of a skew complete intersection R, i.e. polynomial ring modulo an ideal generated by sequence regular normal elements. We compute the derived braided Hochschild cohomology R relative to and show its action on ExtR(M,N) is noetherian for finitely R-modules M N respecting braiding R. When parameters defining are roots unity use define support the...
