Studying the Effects of Heat and Cold Shock on Cell wall Microstructure and Survival of Some LAB in Milk
In this study we investigated the effect of heat shock (42-45°C for 5, 10, 15, 20, 25, 30 minutes) cold shock (4, 0, -5, -10 and -20°C for 2h) on cell wall Microstructure of LAB. Cell wall Changes and micro -damage behavior of LAB under the impact of heat and cold shock was studied by optical microscope and Transmission Electron Microscope (TEM). Treatment of LAB with heat and cold shock had si...
متن کاملEFFECTS OF CU AND SOLUTION HEAT TREATMENT ON THE MICROSTRUCTURE AND HARDNESS OF IN-SITU ALUMINIUM MATRIX COMPOSITE CONTAINING AL4SR PHASE
This study was undertaken to investigate the effects of Cu and solution heat treatment on the microstructure and hardness of cast Al-Al4Sr metal matrix composite. Different amounts of Cu (0.3, 0.5, 1, 3 and 5 wt.%) were added to the composite. Specimens were heat treated at 500 °C for 4 hours followed by water quenching. Microstructural studies were assessed by the use of optical microscope, sc...
متن کاملFluidity Onset Analysis in FG Thick-Walled Spherical Tanks under Concurrent Pressure Loading and Heat Gradient
In this paper,fluidity onset analysis in FG thick-walled spherical tanks under concurrent pressure loading and heat gradient has been presented. Designing thick-walled spherical tanks under pressure as tanks holding fluids under heat loads with high heat gradients require new approaches. Under high internal pressure and high temperature, the tank enters the plastic stage in a part of its thickn...
متن کاملThe Separation of Ferritin and Haemosiderin for Studies in the Metabolism of Iron.
1. Ferritin and haemosiderin in diluted tissue cannot be quantitatively separated by centrifugation unless the pH is brought below 6. 2. These iron-storage substances can be separated from one another and from haemoglobin by ion-exchange chromatography on CM-cellulose, when good recoveries of total tissue iron are obtained. 3. The ferritin fraction has been identified by its solubility, its app...
متن کاملNear-field heat transfer in a scanning thermal microscope.
We present measurements of the near-field heat transfer between the tip of a thermal profiler and planar material surfaces under ultrahigh vacuum conditions. For tip-sample distances below 10(-8) m, our results differ markedly from the prediction of fluctuating electrodynamics. We argue that these differences are due to the existence of a material-dependent small length scale below which the ma...
