background: the consumption of low quality foods is common in low socioeconomic areas; and according to epidemiological studies, the density of nutrients often proves the quality of diet. this study aimed to compare the density of macronutrients and micronutrients in various parts of tehran. methods: this was a cross-sectional study performed from september to december 2007 in all the 22 dist...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
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...
Facial skin cancer is common, and its treatment affects patient's health-related quality of life (HRQoL), as demonstrated by patient-reported outcome measures (PROMs). In this study, we anglicise validate the novel FACE-Q Skin Cancer Module for UK population. Anglicisation followed international guidance cross-cultural adaptation. Cognitive interviews were performed, producing a reconciled harm...
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 ...
first principle calculations were performed using density functional theory within the local spin density approximation (lsda) to understand the electronic properties of au(100)+tbt system and compare the results with au(100) and bulk au properties. band structure, the total dos and charge density for these materials are calculated. we found that the homo for au(100)+tbt becomes broader than au...
objective(s): adsorption of immucillin-a (bcx4430) molecule on the pristine and n-doped tio2 anatase nanoparticles were studied using the density functional theory (dft) calculations. the adsorption energy analysis indicated that tio2+immucillin-a complexes including oc-substituted tio2 have higher adsorption energy than the complexes with ot substituted tio2, thus providing more stable configu...
we have performed density functional theory investigations on the adsorption properties of ammonia molecule on the undoped and n-doped tio2 anatase nanoparticles. we have geometrically optimized the constructed undoped and n-doped nanoparticles in order to fully understand the adsorption behaviors of ammonia molecule. for tio2 anatase nanoparticles, the binding site is preferentially located on...
in nigeria, crowded housing is one of the housing stresses that bother policy-makers and housing authorities.this study examines the crowding levels in seven marital status categories among the occupants of lagos state development and property corporation’s apartments. the focus is on the capacity of an apartment’s internal spaces to meet the sleeping needs of households in different marital ar...
