cells by the rapid release of gas pressure was examined under yarious conditions of pressure, temperature, treatment time and water content of the cells. Wet cells of baker's yeast were completely destroyed, after the microorganisms had been saturated with C02 gas at 40eC and 40 atm for more than 3h when the pressure was suddenly discharged. On the other hand, dry cells were poorly kil}ed even ...

In the content of this study, non-linear consolidation behavior of unsaturated soils was investigated. In this respect a non linear differential equation for consolidation has been proposed. This proposed differential equation and its solutions enlighten both the diffusive characteristics and the time rate of settlement of soils. Besides, this study also enables to perform the matric suction ca...

While water is known to significantly reduce the strength of rocks, there remains a paucity data on water-weakening gypsum. Here, we quantify in natural gypsum facies from Monferrato (Italy) by performing experiments nominally dry, oil-saturated, and water-saturated samples. Uniaxial conventional triaxial revealed significant as well strong strain-rate dependence uniaxial compressive strength. ...

in order to study the effect of irrigation on fatty acid composition, oil and protein content of sunflower cultivars included azargol, allstar, alison and euroflor, an experiment was conducted at experimental field of the agricultural faculty of bu-ali sina university in 2007. treatments were arranged on split plot based on randomized complete block with three replications. the irrigation treat...

Natural biopolymers from plant sources contain many impurities (e.g., fat, protein, fiber, natural pigment and endogenous enzymes), therefore, an efficient purification process is recommended to minimize these impurities and consequently improve the functional properties of the biopolymer. The main objective of the present study was to investigate the effect of different purification techniques...

Feeding dairy cows a ration containing whole flax seeds (linseed), flax (linseed) oil or milled, extruded or micronized linseed has five beneficial effects on the fat profile of cow’s milk: (1) increasing the content of alpha-linolenic acid (ALA); (2) increasing the content of conjugated linoleic acid (CLA); (3) decreasing the omega-6/omega-3 ratio; (4) decreasing the overall saturated fat cont...

[1] In this study, we evaluate the use of ground‐penetrating radar (GPR) to investigate the effects of bacterial activity in water saturated sand. A 90‐day laboratory‐scale controlled experiment was conducted in a flow‐through polycarbonate sandbox using groundwater from the Kansas River alluvial aquifer as inoculum. After 40 days of collecting baseline data, bacterial growth was stimulated in ...

Preventing plastic shrinkage cracks improves the durability of concrete. This is because serve as pathways by which corroding agents can penetrate Freshly cast concrete a saturated mixture reactive and non-reactive materials. As water moves out mass used in hydration process, free reduces. Eventually, be considered to unsaturated. In this research project, viability using soil content sensors m...
