in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
the present study investigates the effect of different exposure densities on third grade iranian junior high school (ijhs) students’ efl development and retention. it also attempts to explore whether there is any differential performance due to type of post-exposure assessment tasks (recognition vs. written production). performances of five groups of learners receiving equal amount of exposure ...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
background: some coincidental disorders with migraine have been introduced that may have role in its pathogenesis or aggravation. in this study we determined the relative frequency of hyperlipidemia as a coincidental disorder in patients affected by migraine. methods: a total of 102 migraine-affected patients according to international headache society (his) criteria and 103 control subjects ad...
the intake of antioxidants intake has been reported to be inversely associated with the incidence of coronary artery disease. to clarify the possible role of lipophilic antioxidants in prevention of atherosclerosis, we investigated the effects of lycopene on the susceptibility of low-density lipoprotein (ldl) to oxidative modification. in this study, “lycopene” was added to plasma and incubated...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
the present study investigated the possibility of replacing salamon with modified shotor diluent (msd) and egg yolk (ey) with low density lipoprotein (ldl) for chilled storage of ram semen. good quality semen (>80% progressive forward motility (pfm) of sperm) from 3 fertile rams was collected using an artificial vagina and pooled for each experiment. low density lipoprotein was extracted from f...
مقدمه:بیماری پریودنتال یک عفونت مزمن لثه است که در بافت های احاطه کننده دندان ایجاد و باعث از دست رفتن دندان می شود. بعلاوه این بیماری می تواند سبب تغییر در فیزیولوژی سیستمیک شود .فردی با التهاب مزمن، مستعد پیشرفت وسیع تخریب بافت و کاهش ظرفیت ترمیم بافتی می باشد. مطالعات مختلف ارتباط بین پریودنتیت ، هایپرلیپیدمی c-reactive protein, و fasting blood sugarرا نشان داده است. این مطالعه با هدف تأثیر ...
background: serum lipids abnormalities have been observed in various forms of cancers including acute leukemia. investigators report decreased total cholesterol and hdl, and elevated triglyceride in leukemic patients. limited studies had been performed to discover the correlation between abnormal lipids profile and disease activity in leukemic patients in iran. this study was done to evaluate t...
abstract probiotic products highly affect the health of consumers by reducing the risk of heart attacks and improving of desirable microflora in intestinal tract. in this study the effect of yogurt (500g/d for 3 wk) enriched with either bifidobacterium bifidum or lactobacillus acidophilus on the level of cholesterol, low density lipoprotein (ldl) and high density lipoprotein (hdl) of serum and ...
