Abstract

Erosion has been a dominant geological process. Erosion of the continental crust removes surface layers bringing hotter regions closer to the surface. Eroded surface layers also have larger radiogenic heat production. Effects of both these on the thermal evolution of crust have been earlier modelled analytically with the help of an advection-diffusion equation model. These processes lead to raising thermal gradient near the surface initially and decreasing later on ,depending on the rate of erosion. The changes in the thermal structure of the near surface region would lead to generation of thermal stresses, changes in the depth of brittle-ductile transition and lateral mass transport below this transition depth. Analytical models developed to quantify thermal effects due to erosion have been summarised and some numerical results, applicable to the south Indian region, are presented.

Keywords

Erosion, Thermal Models, Surface Stress, Lower Crustal Flow, Orogenic Complexity.

Abstract

Pb isotope data were obtained for galena specimens from 5 sulphide occurrences within the Chotanagpur Gneissic Complex (CGC) in eastern Bihar, where the host rock occurs as enclaves within the CGC. Based on galena Pb isotope composition, an attempt has been made to suggest a Proterozoic event of sulphide mineralization related to Precambrian crustal evolution. An age range 1650 to 1700 Ma seems reasonable for the Bihar galena.

Abstract

The thermal structure of Carlsberg Ridge in the northwest Indian Qcean is discussed using the plate model with realistic thermal boundary condition at the ridge axis, which includes the effects of adiabatic cooling, magmatic crystallization and solidification. The elastic and brittle layer boundaries as predicted by the model are shallower when compared with results from earlier studies using gravity-bathymetry data across the ridge and seismicity at the axis of the ridge. In order to explain the observed anomalous structure, we consider hydrothermal circulation as resulting in additional heat loss. This is incorporated in the thermal model by presenting lower temperature in the shallow regions at the axis where fluid flows could occur. The resulting thermal structure explains the observed elastic thickness and brittle layer thickness.

Keywords

Abstract

Desert, comprising one-third of the Earth's surface, was a synonym for 'no life' as it supports very less or no life due to nutritional stress and extreme weather. Microbial autotrophic biochemistry is the principal source of carbon in arid environment, but understanding of these processes in arid ecosystem is limited. Emerging molecular tools have identified associations of phototrophic and chemolithoautotrophic communities often termed as 'biological soil crust' or 'microbiotic crust'. They are the sole sources of carbon and nitrogen, collectively providing soil stability to support vegetation. Here the curiosity arises, whether this phenomenon could be exploited in deserts for carbon sink using microbial community intelligence. By following the precipitation event under regulated nutrient supply that promotes the soil microbial intelligence for autotrophy would enrich soil carbon and nitrogen which in turn support plant growth in desert. Additionally, bioaugmentation of rhizobacteria could enhance the process. This will enable us to refine and formulate our strategies to exploit CO₂-fixing microorganisms in such niches vis-a-vis supporting the carbon sink using microbial community intelligence.

Abstract

Studies conducted on the bionomics of the pteromalid parasitoid, Trichomalopsis apanteloctena Crawford indicate that the reproductive ability of the parasitoid is hindered by the male during oviposition period. The hindrance was caused by the male either by chasing for mating or by antennal encounters during oviposition. The mean fecundity of the female in the presence of male was lower and in the absence it is higher. The mean sex ratio was higher in isolated females than those females that were mixed with male.

Abstract

There may be so many negative consequences of stress for human beings and dissatisfaction among employees happens to be one of the major problems. It indicates negative feelings that individuals have regarding their jobs or its facets. On the other hand, social support is assumed to be mitigating the relationship between negative aspects of the work environment and job satisfaction. Job stress is said to be associated with job dissatisfaction as well as experience of strain. In view of the above, this study examined the role of job stress and social support in job satisfaction. The sample consisted of 30 school teachers from different school of Varanasi (U.P.). The job stress, job satisfaction and social support scales were administered on the participants. The responses of the participants were converted into scores for statistical analyses. The scores of participants on the scales were correlated. The findings revealed that job stress led to increased job satisfaction. It is against the proposed hypothesis and it appears as if the social support received by the participants is a factor behind it. Two of the four dimensions of social support were found to exert positive impact on job satisfaction but the other two dimensions were not found to be correlated with it. The findings are thoroughly discussed and interpreted.

Abstract

Present study was conducted to examine the role of life satisfaction and positive-negative affectivity in well-being among special school educators. Sixty eight special school educators (31 male and 37 female) aging between 26-55 years constituted the sample of the study. They are employed at different schools devoted to educate physically and mentally challenged children. The participants were administered Pandey's positive and negative affect schedule (PANAS), Dtener's satisfaction with life scale and mental health continuum-short form(MHC-SF). The correlational approach was used to see the relationship which revealed that life satisfaction and positive-negative affectivity jointly predict well-being among special school educators. Further analysts indicated that life satisfaction was slightly but positively correlated with positive affectivity, whereas it correlated with negative affectivity negligibly.As regards gender difference, male and female spectal educators did not differ significantly m positive-negative affectivity and life satisfaction. The results are thoroughly discussed and interpreted and implications of the findings are underlined.

Abstract

Temperature dependent physical properties such as ultrasound velocity, density, compressibility and the molar volume are measured for different compositions of water-glycerol mixture. These data are further used to investigate the excess velocity (C^xs), excess adiabatic compressibility (κ_S^xs) and the excess molar volume (V^xs). C^xs at room temperature is found to be positive and exhibits maximum around the concentration of glycerol, x_g≈0.65. C^xs depends strongly on temperature and even becomes negative in the dilute limit of concentration at a temperature, 60°C. κ_S^xs is negative exhibiting maxima at room temperature. The excess volume is found to be positive. These results have been used to analyze the surface properties as well as the nature of interaction between molecules in the mixture.

Keywords

Ultrasonic Velocity, Adiabatic Compressibility, Excess Velocity, Excess Compressibility, Excess Molar Volume.

Abstract

Studies in India and abroad also have revealed that mental health is shaped by the wide-ranging characteristics (including inequalities) of the social, economic and physical environments in which people live and operate. Poor mental health experienced by individuals is a significant cause of so many psychological, social and health problems. In view of it, the present research aimed at examining the differential effects, if any, of socio-economic conditions on women' mental health. A sample of 200 women belonging to Low (n=60), Moderate (n=80) and High (n=60) socio-economic status were selected for data collection. The purposive random sampling method was used in data collection. Their age ranged from 27 years to 55 years. They were administered Socio-economic Status scale (Pandey & Singh, 1997) and Mithila Mental Health Inventory (Kumar & Thakur, 1986). MMHSI provides global as well as dimensional scores - i.e., egocentrism, alienation, extraversion, emotional unstabiltiy and social nonconformity. Data obtained were subjected to descriptive and inferential statistics and socio-economic condition emerged as a potential determinant of mental health of women. The three SES groups differed significantly in experiencing mental health problems. The women from poor socio-economic background appeared to be the worst sufferers from the point of view of their mental health problems. The results are thoroughly discussed in the light of other empirical studies. Besides, implications and limitations of the present study and suggestions for future researches are also underlined.

Abstract

The purpose of this study was to compare the bronchial asthma patients with normal control participants. A group of 50 asthmatic outdoor patients with age range of 40-55 years was purposively sampled. Only those patients were selected who had not gone under long term treatment. The patients belonged to Jaunpur district (U.P. India). A group of 100 normal subjects was also sampled for the comparison purpose. The personality characteristics of both the groups were measured with 16PF questionnaire. The two groups differed significantly on A, C, F, L, N, O, Q1, Q2 and Q3 personality factors. This suggests that bronchial asthma patient group possess different personality constellation as compared to the normal participants. Results are thoroughly discussed and implications are also highlighted.

Abstract

Ground-based observations of Neptune are quite limited. Using early imaging technique, the existence of considerable wind in the Neptunian atmosphere was detected. Using Voyager-2 measurements detailed features of atmospheric processes were reported. After Uranus encounter, the Voyager-2 altitude control system was improved that permitted closer scanning of Neptune and Triton. Extensive searches for new satellites were made and several new satellites were discovered. Considerable amount of methane and hydrogen are present in the Neptunian atmosphere. The condensable were found to enhance by a factor of ten relative to hydrogen and helium abundances in Sun's atmosphere. Some of the details of Triton's ionosphere are also shown. Solar wind interacts with the Neptune's ionized region and forms magnetosphere.
