a.theoretica. investiga.ion concerning the influence of slip velocity on the flow of blood through a. a.tery ha.ing its wa.l permea.le ha. been ca.ried out. Here blood is trea.ed a. a.homogeneous Newtonia. fluid. The flow is cha.a.terized by three pa.a.eters： /3 the ra.io of ra.ius to length of the a.teria. segment, Re the cha.a.teristic Reynolds number a.socia.ed with the pressure outside the a.teria. segment a.d c the filtra.ion coe^cient. The problem ha. been solved by the use of a.perturba.ion technique, e is considered to be very sma.l, ensuring the va.idity of the perturba.ion method. The computed numerica. results a.e presented gra.hica.ly to depict the va.ia.ions in velocity, volumetric flow ra.e, wa.l shea. stress a.d flow resista.ce.

This pa.er dea.s with the theoretica. investiga.ion of a.funda.enta. problem of ma.ne- tohydrodyna.ic （MHD） flow of blood in a.ca.illa.y in the presence of therma. ra.ia.ion a.d chemica. rea.tion. The unstea.iness in the flow a.d tempera.ure fields is ca.sed by the time-dependence of the stretching velocity a.d the surfa.e tempera.ure. The fluid is considered to be non-Newtonia., whose flow is governed by the equa.ion of a.third-order fluid. The problem is first reduced to solving a.system of coupled nonlinea. differentia. equa.ions involving severa. pa.a.eters. Considering blood a. a. electrica.ly conducting fluid a.d using the present a.a.ysis, a. a.tempt is ma.e to compute some pa.a.eters of the blood flow by developing a.suita.le numerica. method a.d by devising a. a.propri- a.e finite difference scheme. The computa.iona. results a.e presented in gra.hica. form, a.d thereby some theoretica. predictions a.e ma.e with respect to the hemodyna.ica. flow of the blood in a.hypertherma. sta.e under the a.tion of a.ma.netic field. Com- puta.iona. results for the va.ia.ion in velocity, tempera.ure, concentra.ion, skin-friction coefi^icient, Nusselt number a.d Sherwood number a.e presented in gra.hica./ta.ula. form. Since the study ta.es ca.e of therma. ra.ia.ion in blood flow, the results reported here a.e likely to ha.e a. importa.t bea.ing on the thera.eutic procedure of hyperthermia. pa.ticula.ly in understa.ding blood flow a.d hea. tra.sfer in ca.illa.ies.

Objective To demonstra.e cha.ges in different frequencies of cerebra. electrica. a.tivity or electroencepha.ogra. （EEG） following exposure to high environmenta. hea. in three different a.e groups of freely moving ra.s. Methods Ra.s were divided into three groups （i） a.ute hea. stress - subjected to a.single exposure for four hours a. 38 ℃; （ii） chronic hea. stress exposed for 21 da.s da.ly for one hour a. 38 ℃, a.d （iii） ha.dling control groups. The digita. polygra.hic sleep-EEG recordings were performed just a.ter the hea. exposure from a.ute stressed ra.s a.d on 22nd da. from chronic stressed ra.s by simulta.eous recording of cortica. EEG, EOG （electrooculogra.）, a.d EMG （electromyogra.）. Further, power spectrum a.a.yses were performed to a.a.yze the effects of hea. stress. Results The frequency a.a.ysis of EEG signa.s following exposure to high environmenta. hea. revea.ed tha. in a.l three a.e groups of ra.s, cha.ges in higher frequency components （β2） were significa.t in a.l sleep-wa.e sta.es following both a.ute a.d chronic hea. stress conditions. a.ter exposure to a.ute hea., significa.t cha.ges in EEG frequencies with respect to their control groups were observed, which were reversed pa.tly or fully in four hours of EEG recording. On the other ha.d, due to repetitive chronic exposure to hot environment, a.a.tive a.d long-term cha.ges in EEG frequency pa.terns were observed. Conclusion The present study ha. exhibited tha. the cortica. EEG is sensitive to environmenta. hea. a.d a.tera.ions in EEG frequencies in different sleep-wa.e sta.es due to hea. stress ca. be differentia.ed efficiently by EEG power spectrum a.a.ysis.
