In the present paper, we presented the study of complaints on thirteen (13) different health symptoms faced by inhabitants living near mobile tower – Global System for Mobile Communication (GSM 900) and those inhabitants living in the area where there is no mobile tower. The study was conducted in two different localities in Aizawl in the year 2014. For the study, questionnaires were conducted in both the localities. Power densities were measured in different places in both the localities. Frequency spectrum was taken in each locality. Health complaints between the two localities were compared. It was found that power density is much higher in the area where there is mobile tower than the area where there is no mobile tower. Inhabitants living near mobile tower are having more health complaints than those inhabitants living in the area where there is no mobile tower. Responses from inhabitants who participated in the questionnaire from both the localities were statistically analysed and compared by performing Kruskal Walli’s t-test. Out of the thirteen (13) different symptoms studied it was found that the comparisons are statistically significant with p < 0.05 in six (6) symptoms. Women were statistically more affected (p < 0.05) than

Abstract

The energy band structure and the optical response of the filled skutterudite CeRu4As12 have been studied using the full-potential linearized augmented plane wave (FP-LAPW) method within the local density approximation (LDA). The analysis of the region close to the Fermi energy level suggests the narrow band gap (0.18 eV) semiconducting nature of the material. The new approach of the exchangecorrelation functional called the modified Becke Johnson potential used in the treatment of the material gives an enhanced band gap value of 0.2 eV. The elastic parameters are also estimated at the ambient condition, which indicates the brittle nature of the studied material. The study of the optical spectra suggests the metallic behavior of the material in the far infrared region, which indicates that it acts as an opaque material with superluminal behavior in the ultraviolet frequency.
