Increasing efficiency and decreasing cost are the main purposes in the design of the power generation systems. In this study two hybrid systems: solid oxide fuel cell (SOFC)-gas turbine (GT) and SOFC-GT-steam turbine (ST); are considered. Increasing the SOFC input temperature causes thermodynamics improvement in the hybrid system operation. For this purpose, using two set of SOFC reactants heat...

Probably the most common approach in the industry, particularly for frozen blocks, is to drill and probe. This doesn’t really measure “freeze time”, but it does tell the operator what the approximate core temperature is at the end of the freezing cycle. “Temperature Measurement and Fish”, the Torry Advisory Note of J.Graham (1977), gives a good account of these practices. The procedure for dril...

In this work, two types of solvents ethanol or water were used in preparation of the LaFeO3 catalysts by citrate sol gel method. The obtained samples were subjected to various calcination temperatures in order to study the catalytic activity and stability for methanol electro-oxidation by XRD, cyclic voltammetry and chronoamperometry. The crystallinity of the LaFeO3 ph...

Determination of the type of precipitated calcium sulfate in mixing two incompatible injection and formation waters was studied experimentally in this work at two temperatures of 26oC and 80oC. Here the SEM, EDX and XRD techniques have been used to inspect the temperature effects on the morphology, type, and size of the precipitated calcium sulfate crystals. The result...

of reduced glutathione was detected and this decrease was fo11owed by a decrease in leyels of glucose 6-phesphate. When twigs that contained depressed leyels of reduced glutathione and glucose-6-phosphate were transferred to 40C, oyercompensation for the decrease in reduced glutathione and glucose-6-phosphate occurred and the resultant surplus appeared to reflect the metabolic dysfunction in th...

objective(s) physiological changes in the body may be utilized as potential triggers for controlled drug delivery. based on these mechanisms, stimulus-responsive drug delivery has been developed. materials and methods in this study, a kind of poly (n-isopropylacrylamide-acrylamide) membrane was prepared by radical copolymerization. changes in swelling ratios and diameters of the membrane were i...

The development of cephalopods early life stages is strongly influenced by environmental variables, especially temperature. Octopus tehuelchus (d'Orbigny, 1834) an Atlantic Patagonian fishery resource currently being studied as a new species for cultivation; however it not known how temperature modulates its stages. In this work, egg masses were artificially incubated at 13 and 16 °C under cont...
