Anchovy fillets that had undergone osmotic dehydration and response surface methodology (RSM) were used to determine the influence and optimal values of the process variables. Also the optimal processing conditions were determined in order to reduce the solid gain and water loss ratio (SG/WL) and firmnessfor the anchovy fillets. A three-levelcentral composite rotatabledesign (CCRD) involving th...

biodegradation of phenanthrene (phe) was studied in aqueous culture to demonstrate the potential of the mixed culture in degrading high concentration of phe. the experiments were conducted to monitor biodegradation of phenanthrene for duration of 6 days. biodegradation of phe was successfully achieved in low and middle concentration by the isolated mixed culture. a full factorial central compos...

Heat exchangers are one of the most important devices of mechanical systems in modernsociety. Most industrial processes involve the transfer of heat and more often they requirethe heat transfer process to be controlled. A heat exchanger is the heat exchanged betweentwo media, one being cold and the other being hot. There are different types of heatexchanger, but the type which is widely used in...

the reduction of fe2o3 powder at the top layer by the volatiles from high volatile (hv) bituminous coalat the bottom layer of a multilayer powder geometry including a separating alumina layer was studied.the simultaneous effects of the alumina layer thickness, time, temperature and the weight of coal onthe amount of reduction and coal devolatilization were studied by implementing a rotatable ce...

This aim of this study was to assess the hydrolysis reaction of the biomass of Chlorella pyrenoidosaandSpirulinasp. LEB 18,using commercial proteases that act in different pH ranges, to obtain protein hydrolysates with promising application in food or food supplement, improving functional and nutritional food properties. Threecentral composite study designs were carried out for each microalga (...
