conclusions our results demonstrated the antimicrobial properties of frog skin as a wound dressing, which has antimicrobial effects per se. this biological dressing shows promise as an effective biological wound dressing insofar as not only is it capable of resisting microbes and accelerating wound healing but also it is cost-effective and easy to use. results in the microbial studies, the bact...

  According to statistics released by agricultural insurance fund (AIF) less than 4 million acres out of 90 million acres has been covered by Pastures Insurance. This observation along with several facts motivated authors to study possible barriers which Pastures Insurance has been encountered in practice. The research population included all the experts in agricultural insurance fund. Small po...

A new Row-by-Row Dynamic Source-line Voltage control (RRDSV) scheme is proposed to reduce the active leakage as well as the stand-by leakage in SRAM. By dynamically controlling the source-line voltage of cells row by row, the cell leakage through inactive cells can be reduced by two orders of magnitude. Moreover, the bit-line leakage through pass transistors can be completely cut off. This leak...

We investigate the motion of suspended particles past a single line of equally spaced cylindrical posts that is slanted with respect to the driving force. We show that such a line of posts can fractionate particles according to their size, with small particles permeating through while the larger particles are deflected by the steric barrier created by the posts, even though the gaps between pos...

Core-shell nanoparticles consisting of silica as core and surface-grafted poly(dimethylsiloxane) (PDMS) as shell with different diameters were prepared and used as heterogeneous nucleation agents to obtain CO2-blown poly(methyl methacrylate) (PMMA) nanocomposite foams. PDMS was selected as the shell material as it possesses a low surface energy and high CO2-philicity. The successful synthesis o...

background: dielectric barrier discharge (dbd), a source of non-thermal plasma, is used in surface decontamination. objective: to study the effect of dbd plasma treatment, we evaluated the effect of plasma exposure time on inactivation of bacillus subtilis. results: applying the dbd plasma to the culture of b. subtilis caused complete sterilization of the surface without any thermal effects. in...

shiga toxins (stxs) are bacterial virulence factors produced by shigella dysenteriae serotype 1 and escherichia coli strains. stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. additionally, stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. the inflammatory cyto...

barrier properties are one of the most important factors in the edible film. in this study, edible mungbean films were prepared containing (0%, 15%, 30%, 45%) concentrations of rosemary aqueous extract. then the effect of rosemary was investigated on colorimetric and barrier properties (water vapor permeability, oxygen permeability). rosemary extract increased the absorption of color in the vis...

in this research, high oxygen-barrier films were organized based on low-density polyethylene (ldpe)/ ethylene vinyl alcohol (evoh)/ polyethylene-grafted maleic anhydride (ldpe-g-ma) compatibilizer. the effects of 10–30 wt. % evoh and 0–10 wt. % ldpe-g-ma loadings on the properties of final films were evaluated. the morphology of specimens was observed by using scanning electron microscopy (sem)...

introduction: development of brain edema following focal cerebral ischemia exacerbates primary ischemic injury. blood brain barrier (bbb) opening is an important part of edema named as vasogenic brain edema. in this study, quantitative alterations of bbb permeability is experimentally evaluated using transient focal cerebral ischemia in the rat. methods: two groups of male rats (ischemic and sh...
