This study developed probabilistic models to determine the initiation time of growth of Pseudomonas spp. in combinations with NaNO2 and NaCl concentrations during storage at different temperatures. The combination of 8 NaCl concentrations (0, 0.25, 0.5, 0.75, 1, 1.25, 1.5, and 1.75%) and 9 NaNO2 concentrations (0, 15, 30, 45, 60, 75, 90, 105, and 120 ppm) were prepared in a nutrient broth. The ...
The correlation between molecular changes and microstructural evolution of rheological properties has been demonstrated for the first time in a mixed anionic/zwitterionic surfactant-based wormlike micellar system. Utilizing a novel combination of DLS-microrheology and Raman Spectroscopy, the effect of electrostatic screening on these properties of anionic (SLES) and zwitterionic (CapB) surfacta...
To determine whether age-related changes in salt preferences occur over the lifespans of spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY), the same animals of each genotype were tested as juveniles, and as young and older adults. Taste preference ratios for NaCl and KCl, at concentrations from 0.001 to 1.0 M, were calculated using 24-hour, two-bottle preference tests of each sa...
This study developed probabilistic models to determine the initiation time of growth of Pseudomonas spp. in combinations with NaNO 2 and NaCl concentrations during storage at different temperatures. The combination of 8 NaCl concentrations (0, 0.25, 0.5, 0.75, 1, 1.25, 1.5, and 1.75%) and 9 NaNO 2 concentrations (0, 15, 30, 45, 60, 75, 90, 105, and 120 ppm) were prepared in a nutrient broth. Th...
the purpose of this study was to investigate how english language teachers in mashhad who teach students in the pre-university cycle perceived the impact of the efltee on their teaching. the target population was nearly all pre-university english language teachers in seven districts of mashhad in the scholastic year 2008/2009. a survey questionnaire which consisted of (36) likert type items, wa...
To investigate the effects of saline stress on seed germination, ion distribution, and organic solutes changes of sunflower (Helianthus annuus L.), in the present study, seeds and 3-week-old seedlings were subjected to a series of external NaCl concentrations (5–200 mmol). The results showed that high salinity (200 mmol) remarkably inhibited the germination of seed and delayed germination time ...
The equilibria of methane and carbon dioxide clathrate hydrates were measured in presence a pure-quartz porous sand, with without NaCl. Two different salt concentrations tested: 0.030 0.037 wt%. Results compared phase equilibrium data already present literature for these species. Despite salt, the medium was found to promote process, mainly increased surface/volume ratio improved heat transfer....
the present paper investigates how far ideologies can be tease out in discourse by examining the employed schemata by two ideologically opposed news media, the bbc and press tv, to report syria crisis during a period of nine months in 2011. by assuming that news is not a valuefree construction of facts and drawing on micro structural approach of schema theory, for the first time in discours...
iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
Background and Aim: The aim of the present study was to investigate the effect of Garlic extract on cortical spreading depression (CSD) specifications as underlying mechanism of aura and subsequent pain in migraine in rats' neocortical slices. Materials and Methods: In this experimental study, CSD was induced in rats' somatosensory cortical slices using two models as follows: first, after KCl m...
