According to the characteristics of low-carbon steel pitting acoustic emission signal, one new characteristic analysis-WICA is proposed. The main idea of WICA is that based on the independent component analysis blind source separation technology as well as the wavelet transformation decomposition technology, proposed determines the low-carbon steel pitting source number according to the energy ...

There is accumulating evidence that virus-like particles (VLPs) recombinantly produced in Saccharomyces cerevisiae (S. cerevisiae) are characterized by low structural stability, and that this is associated with reduced antigenicity and immunogenicity. However, little attention has been devoted to methods of improving the quality of the VLPs. Here, we investigated the effect of carbon source con...

Structural and mechanical properties of diamond-like carbon films deposited by an anode layer source, Thin Solid Films 517 (2009) 6502. spectroscopy of diamond-like carbon films deposited by an anode layer source, Diamond Relat. Mater. 17 DLC films deposited at room-temperature by reactive magnetron sputtering and by an anode layer source – a comparative study, Relation between structural/topol...

3-Dehydroshikimic acid is a hydroaromatic precursor to chemicals ranging from L-phenylalanine to adipic acid. The concentration and yield of 3-dehydroshikimic acid microbially synthesized from various carbon sources has been examined under fed-batch fermentor conditions. Examined carbon sources included D-xylose, L-arabinose, and D-glucose. A mixture consisting of a 3:3:2 molar ratio of glucose...

The application of carbon dioxide as natural refrigerant in commercial refrigeration systems has attracted higher interest in recent years for its promising energy efficiency and ecological sustainability. This paper presented the development of a low side scroll compressor for the bottle cooler application in the trans-critical cycle. Experimental tests were performed in two different temperat...

microbial cells are producers of natural polymers present in plant cells. production of pullulan (an extracellular microbial polysaccharide) by aureobasidium pullularia pullulans (p. pullulans) was studied under fermentation conditions, and kinetic parameters were determined. pullulan formation obeyed a growth and non-growth associated term. phb (polyhydroxybutyrates) an intracellular biopolyme...
