Background: Many studies have showed that electromagnetic field decrease anxiety. In this study the objectives: effect of Electromagnet Fields in Low Frequency in Induced Anxiety by formalin. Methods: 32 male mice with weight (30 grams) were classified in 4 groups (n=8), and received Histamine (5mg/kg IP injection) 3classes of every group exposed to electromagnetic field (emfs) with25, 50, 75 H...
This article aims to examine the Ṣūfī interpretation of story prophet Jesus in Qurʾān. The fate Jesus, who came world a miraculous way, resulted similar way. fact that verses Qur’an mention Jews wanting kill him (as well as other verses) do not state what his ultimate was has been focus much discussion. interpretations made by Ṣūfīs, put forward different method Islamic tafsīr tradition terms t...
Today there are different vibration isolators used in industries according to the weight and excitation frequency of the machines which have vibration. One of them is Air Spring which is in two types: Convoluted air spring and membrane air spring. Convoluted air springs are used to control vibrations in low frequency (usually lower than 10 Hz) and the membrane ones are used in high frequenc...
Background and Objective: Use of extremely low frequency magnetic field) ELF-MF (has been reported in increasing blood sugar, cholesterol, triglyceride and reduction of withdrawal syndrome signs of morphine. Since pain is one of the main considerations and usually analgesic drugs are not very useful and have side effects, therefore, the present project was carried out using formalin test to eva...
introduction: the effects of electromagnetic fields on biological organisms have been a controversial and also interesting debate over the past few decades, despite the wide range of investigations, many aspects of extremely low frequency electromagnetic fields (elf/emfs) effects including mechanism of their interaction with live organisms and also their possible biological applications still r...
In this paper, multivariate calibration methods of partial least squares (PLS) and principle component regression (PCR) were investigated in simultaneously determination of hydrazine (HZ) and acetylhydrazine (AHZ). The aforementioned methods are based on formation of the silver nanoparticles (AgNPs) from the reaction of HZ and AHZ with Ag+ ions as oxidizing agent in the presence of citrate ions...
Sound is an effective exogenous factors which affecting human brain processing mechanisms. This research was quasi experimental study that was carried out among 70 students to evaluate the effect of sound frequency on human noise annoyance. Noise annoyance degree was measured during exposure to sound at various frequencies of 500, 1000, 2000, 4000 and 8000 Hz. Sound.exe software was used to det...
