| Abstract | In this paper, the Pennes bioheat equation with a thermoregulatory model is used for numerical modelling of local peak temperatures as well as the body core temperature elevation in a realistic human body model for plane-wave exposures at frequencies 39, 800 and 2400 MHz. The electromagnetic power absorption is solved numerically using the FDTD method and the resulting temperature rise is solved from the bioheat equation for various different combinations of modelling parameters, such as the skin blood flow rate, models for vasodilation and sweating, and clothing and air movement. The results show that ignoring the thermoregulation and the blood temperature increase is a good approximation when the local 10-g averaged specific absorption rate is smaller than 10 W $kg^{−1}.$ The most dominant thermophysiological factors affecting the peak temperature rises are related to the modelling of the tissue blood flow and its temperature dependence, while the body-core temperature rise is dominantly affected by the modelling of the sweating response. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
