Rice is only second to wheat as a major food for Iranians. It has to be dried for processing and/or storing due to excessive moisture content after harvesting. In most parts of Iran, rice is sun-dried by spreading it on the ground under solar radiation which leads to excessive losses such as attacking birds and rodents, grain contamination, wind and rainfall hazards, as well as thermal and mois...
Because most shrinkage-reducing admixtures (SRAs) significantly reduce the surface tension of a cement paste pore solution, they will naturally influence all physical properties and processes that are dependent in some way on surface tension. Such properties include internal relative humidity, capillary stresses, and freezing point depression, all via the Kelvin equation and its variants (Kelvi...
Amphiphilic phospholipids were used to direct the formation of biocompatible, uniform silica nanostructures in the presence of Saccharomyces cerevisiae and bacterial cell lines. The cell surfaces organize multilayered phospholipid vesicles that interface coherently with the silica host and help relieve drying stresses that develop with conventional templates. These host structures maintain cell...
Abstract Ship-induced wave wash affects the hydromorphological and ecological state of rivers through various mechanisms. The direct proximity riverbank is usually most exposed, as hydrodynamic stresses are highest in these shallow water areas. Contrary to steady almost still, natural flow conditions (i.e., no waves anthropogenic source), shoaling breaking ship increase by orders magnitudes, ha...
This study presents the development of a method for washcoating Ni/boehmite gels, prepared by sol–gel process, onto surface commercial ceramic monolith. Indeed, cordierite monolith in honeycomb shape was used as substrate Ni/Al2O3 deposition. An experimental assembly made order to apply coating on surface. Different suspensions were with various viscosities, and multiple parameters tested withd...
Given the increasing commercial and clinical relevance of probiotic cultures, improving the technological robustness of what are often process-sensitive cultures is an important biological goal. The nisin-controlled expression system was used to direct the heterologous expression of the listerial betaine uptake system BetL in the probiotic strain Lactobacillus salivarius UCC118. Following nisin...
several methods are available to produce haploid plants. one of the most efficient methods is especially microspore culture. stress as a triggering factor is essential for embryogenesis induction in microspores. in the first experiment, the effect of different thermal stresses including cold treatments and heat stress and the control were evaluated. in the second experiment, the effect of 2,4-d...
