زمینه و هدف: امروزه با استفاده از تکنولوژی ارتباطی مودم بی سیم(wi-fi)، می توان تبادل اطلاعات کرده و یا به اینترنت وصل شد، که این کار با استفاده از پرتوهای ریزموج (میکروویو) 4/2 گیگا هرتز انجام می شود. با توجه به گسترش روزافزون استفاده از این تکنولوژی و خطرات احتمالی بر بافت های موجود زنده، نگرانی در مورد زیان های احتمالی آن نیز رو به افزایش است. هدف اصلی این مطالعه بررسی اثرات زیستی زمان مواجه...
in this paper we formulate and prove some xed and common xed pointtheorems for self-mappings dened on complete lower transversal functionalprobabilistic spaces.
“hedayat al-motealemin fi teb”, written by abobakr ebn ahmad akhaveini in the fourth century, (ah) is his only book left to the present time. from historical prospective, it is, by far, the first medicine book written in farsi. today, there are only three copies of the book kept in badlyan libraries of oxford, fateh library of istanbul and malek library of tehran. the reviews done on the three ...
Introduction: Common viola, scientifically called viola odorata, has had many therapeutic applications since long ago. In Traditional Persian Medicine (TPM) sources, it has a cool and wet nature and is used for different diseases. Due to the low side effects and numerous beneficial effects of violet, this review study was conducted to evaluate Viola Odorata from the Persian medicine sources' pe...
Introduction: Use of wireless devices have been increasing during the last three decades in the world. Health risks caused by exposure to these appliances has become a public concern. The purpose of this study was to investigate the effects of exposure to Wi-Fi on DNA breaks and oxidative stress parameters. Methods:16 male mice divided in 2 groups; experimental (exposed) (n=8) and the control ...
این مطالعه در سال 1389 در قالب یک طرح کاملاً تصادفی با سه تیمار آبیاری کامل (FI) و آبیاری ناقص ریشه در دو سطح 75% (PRD75) و %55 (PRD55) و با سه تکرار جهت تعیین روند تغییرات EC و دما در محدوده ریشه گیاه ذرت در مزرعه پژوهشی دانشگاه علوم کشاورزی و منابع طبیعی ساری انجام شده است. نتایج حاکی از وجود یک رابطه خطی با ضریب همبستگی بالا بین میزان EC و دمای خاک با تغییرات رطوبت و یک رابطه نمایی بین تغییرا...
background: the use of devices emitted microwave radiation such as mobile phones, wireless fidelity (wi-fi) routers, etc. is increased rapidly. it has caused a great concern; the researchers should identify its effects on people's health. we evaluated the protective role of vitamin c on the metabolic and enzymatic activities of the liver after exposure to wi-fi routers. material and methods: 70...
background: wi-fi allows electronic devices such as laptops to exchange data or connect to a network resource. the main goal of this study was to assess the bioeffects of short term exposure to 2.4 ghz microwave radiation emitted from a common wi-fi router on sperm quality. materials and methods: male wistar rats were divided into 7 groups; i, sham exposed 4 h/day for 7days at 30 cm from the r...
Super Wi-Fi is a Wi-Fi-like network built upon TV white spaces (TVWS) exploiting cognitive radio (CR) techniques. Super Wi-Fi is expected to achieve larger coverage than today’s Wi-Fi thanks to its superior propagation characteristics, while suffering from smaller bandwidth compared to Wi-Fi (6–8 MHz versus 20 MHz) which limits its network capacity. Therefore, it has been a common belief that S...
