Stress conditions have been found to change the susceptibility of hosts or their offspring to infection. The usual method of testing at just one parasite dose level does not allow conclusions on the distribution of susceptibility. To better understand the epidemiology and evolution of host-parasite systems, however, knowledge about the distribution of host susceptibility, the parameters that ch...
BACKGROUND The fractional concentration of exhaled nitric oxide (FeNO) is a biomarker of airway inflammation that has proved to be useful in investigations of genetic and epigenetic airway susceptibility to ambient air pollutants. For example, susceptibility to airway inflammation from exposure to particulate matter with aerodynamic diameter < =2.5 μm (PM2.5) varies by haplotypes and promoter r...
Although the long-neglected field of human susceptibility to environmental toxicants is currently receiving renewed attention, there is only scant literature on factors influencing susceptibility to heavy metals. Genetic factors may influence the availability of sulfhydryl-containing compounds such as glutathione and metallothionein, which modify the distribution and toxicity of certain metals....
this study was intended to analyze the listening tapescripts of the elementary and pre-intermediate levels of total english textbooks from the pragmatic dimension of language functions and speech acts in order to see whether the listening tasks are pragmatically informative or not. for this purpose, 8 conversations from the two books were selected randomly, and then, the two pragmatic models of...
چکیده در این پایان نامه ضمن معرفی توزیع وایبل، برآوردگر درستنمایی ماکزیمم و بیز پارامتر مقیاس توزیع وایبل با داده های سانسور شده را با استفاده از توزیع پیشین جفری و توزیع پیشین جفری تعمیم یافته تحت توابع میانگین مربع خطا و میانگین درصد خطا محاسبه و با یکدیگر مقایسه شده اند. در پایان ضمن مقایسه کارایی برآوردگرها نتیجه می شود که پارامتر برآورد شده توزیع وایبل بدست آمده از روش بیز با توزیع پیشین ...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
