| Abstract | This study was designed to evaluate the EM effects of mobile phone on rats' brain. 23 female Wistar Albino rats weighing 120-150 g were divided into two groups. In the first group, test animals that consist of 9 rats were exposed to mobile phone 2/spl times/30 min/day during four weeks. The specific gravity values of rats' brain were assessed in 5 of them and the blood-brain barrier activity were tested in 4 of them. The results were compared with control animals that they were kept in the same condition without exposing to radiation. It was not observed any apparent difference between control and test group results. The second group that consists of 6 rats was used to investigate the temperature effect of mobile phones on brain. They were exposed by mobile phone and helix antenna fed by 900 MHz, 2 W, RF signal generator for 6 min. The temperature variation was recorded by fluoroptic thermo probes in the subcutane and 2 mm deep under duramater at the upper part of the ear. After each exposure, 5 min intervals were applied to provide thermal equilibrium in brain tissue. The maximum temperature increases is 0.31/spl deg/C in the brain and 0.93/spl deg/C in the subcutane. SAR values were obtained from the measured temperatures for different EM fields. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
