Euglena gracilis is able to synthesize adenosine triphosphate under anaerobic conditions through a malonyl-independent fatty acid synthesis leading to wax ester fermentation. Mitochondrial fatty acid synthesis uses acetyl-CoA and propionyl-CoA as C2- and C3-donors for de novo synthesis of even- and odd-numbered fatty acids, respectively. Euglena's wax ester fermentation has only been described ...

Paraffin melting is widely used in the fields of phase change materials energy storage, gathering and transportation pipe-line paraffin removal, etc. Analysis mechanism influencing factors circular tube deeply has important guiding significance for improving heat storage capacity by changing structure material device ensuring safe crude-oil pipe-line. A double distribution lattice Boltzmann mod...

The depletion of non-renewable energy sources and negative effects towards the environment push research widespread adoption renewable such as solar energy. main drawback panels is that temperatures above 27°C will result in an efficiency drop 0.1-0.5%/°C. In previous studies, usage photovoltaic thermal (PVT) systems was mainly for purpose heating water, warming buildings, drying crops. This fo...

Abstract Background Browning spot (BS) disorders seriously affect the appearance quality of ‘Huangguan’ pear and cause economic losses. Many studies on BS have mainly focused physiological biochemical aspects, molecular mechanism remains unclear. Results In present study, structural characteristics with were observed via scanning electron microscopy (SEM), water loss brown spots evaluated, tran...

Most reservoir fluids contain heavy paraffinic compounds that may precipitate as a solid or solid like material called wax if the fluid is cooled down. Wax precipitation is a phenomenon of considerable importance in oil industry. An increase in aggregation results in enhanced oil viscosity. This however causes significant negative effects on production, transportation and processing of crude oi...

Potassium chloride (KCl) is a highly water soluble substance which is usually used to prevent hypokalemia. Oil in water disperse phase encapsulation method was used to prepare KCl loaded microcapsules using beeswax and carnauba wax as a hydrophobic matrix. The morphology and characteristics of KCl loaded microspheres were studied using scanning electron microscopy (SEM), photon correlation spec...

investment casting is a versatile manufacturing process to produce high quality parts with high dimensional accuracy. the process begins with the manufacture of wax patterns. the dimensional accuracy of the model affects the quality of the finished part. the present study investigated the control and optimization of dimensional deviations in wax patterns. a mold for an h-shaped wax pattern was ...
