سازه های دریایی به دلیل اهمیت راهبردی حمل ونقل دریایی از جمله کلیدی ترین بناها، در مجموعه ساخت وساز کشوری می باشند. بشر با احداث بنادر و سازه های ساحلی در حقیقت باعث تغییر در الگوی جریانات ساحلی و به تبع آن تغییر در الگوی رسوب گذاری می شود. به واسطه جابجایی رسوبات ساحلی، مسئله رسوب گذاری سواحل و فرسایش در سواحل مطرح می گردد که هر یک از این پدیده ها، کاربری تأسیسات و سازه های ساخته شده در دریا ر...
Abstract To avoid formation of the photo-inactive δ -phase formamidinium-cesium lead triiodide, copper or germanium was added to perovskite compounds stabilize photoactive α -phase. It found that substitution by (Ge) (Cu) provided stabilization in present work. The first-principles molecular dynamics calculations indicated displacements formamidinium molecules were suppressed Ge doping. X-ray d...
Post-synthetic modifications of nucleic acids have long been known to affect their functional and structural properties. For instance, numerous different chemical modifications modulate the structural organization, stability or translation efficiency of tRNAs and rRNAs. In contrast, little is known about modifications of poly(A)RNAs. Here, we demonstrate for the first time that the two well-stu...
Introduction: One of the main goals of public health is reducing the disability-related age in elderly. On the one hand, older women especially in the low social and economic class, more experience chronic diseases and disabilities therefore, it is important to be identified women at risk in order to improve their health according to their needs. Since the concept of health in elderly depends o...
Individual cells from a genetically identical population exhibit substantial variation in gene expression. A significant part of this variation is due to noise in the process of transcription that is intrinsic to each gene, and is determined by factors such as the rate with which the promoter transitions between transcriptionally active and inactive states, and the number of transcripts produce...
conclusions aerobic exercise program improved the quality of life as well as the physiological indicators. physical activities can be used as both appropriate model and nonpharmaceutical approach to prevent and cure some diseases. background studies show that lack of exercise and physical activity during childhood and teenage years is directly related to different diseases in adulthood. objecti...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
Background & objectives: Vitamin D deficiency and poor sleep quality are important factors in health disorders and are common among women. The aim of this study was to investigate the effect of physical activity on vitamin D levels and improving sleep quality in women. Methods: This descriptive-analytical study was conducted on active and inactive women (85 individuals in each group), aged 30...
Introduction: The rapid growth of the elderly population and the sedentary and mechanical lifestyle of the present age, on the other hand, double the physical, psychological, social and economic problems in old age and affect the quality of life of individuals. Therefore, this study aimed to investigate the relationship between physical activity and various dimensions of quality of life in the ...
