Estimation of hydraulic parameters in coastal aquifers is an important task in groundwater resource assessment and development. An attempt is made to estimate these parameters using geoelectrical data in combination with pore-water resistivity of existing wells. In the present study, 29 resistivity soundings were analysed along with 29 water samples, collected from the respective dug wells and boreholes, in order to compute hydraulic parameters like formation factor, porosity, hydraulic conductivity and transmissivity from coastal region of north Sindhudurg district, Maharashtra, India. The result shows some parts of the study area reveal relatively high value of hydraulic conductivity, porosity and transmissivity. Further, a negative correlation is seen between hydraulic conductivity and bulk resistivity. The hydraulic conductivity is found to vary between 0.014 and 293 m/day, and the transmissivity varied between 0.14 and 11,722 m2/day. The transmissivity values observed here are in good correspondence with those obtained from pumping test data of Central Ground Water Board. These zones also have high aquifer thickness and therefore characterize high potential within the water-bearing formation. A linear, positive relationship between transverse resistance and transmissivity is observed, suggesting increase in transverse resistance values indicate high transmissivity of aquifers. These relations will be extremely vital in characterization of aquifer system, especially from crystalline hard rock area.

UNSTRUCTURED DattaMeghe Institute of Medical Sciences has been declared as Deemed to be University [DMIMS (DU)] under section 3 of UGC Act, 1996 in the year 2005. The University examinations are conducted as per the rules, regulations and guidelines issued by the various Apical councils of India from time to time. The first University exam was conducted in the year 2006. DMIMS (DU) has initiated various reforms by its own in assessment and evaluation process based on needs. For any system to thrive, it needs to be constantly upgraded and critically evaluated. Therefore, a study is undertaken with this in mind and thereby aimed at evaluation and validation of the assessment and evaluation reforms formulated and implemented at DMIMS (DU) since its inception (year 2006).Need analysis for the assessment and evaluation reforms will be carried out on the basis of feedbacks and reports received from respective stakeholders (Students, Faculty and External examiners) from time to time. Outcome analysis of the Feedbacks and reports will be done subsequently after the implementation of the assessment and evaluation reforms. Further based on the outcome analysis, reforms will be validated into following parameters: Objectivity, Responsiveness, User friendliness, Residual component (not covered in above 3 parameters)and a satisfactory index will be derived. If satisfactory index for reform is 100%, it will be concluded that reforms are well received and good to excellent in nature. Total 33 assessment and evaluation reforms have beenimplemented since year 2006. These reforms will be categorised into Pre-Examination (n=18), On Site Examination (n=05) and Post Examination (n=10), and in each category, they will befurther classified into academic (Total =15) and administrative (Total = 18) on the basis of their domain for the ease of structuring and implementation.All the 33 reforms will be validated on the basis of defined parameters. They will be found satisfactory.

This chapter covers extremes of temperature conditions, physiological effects, and prevention. All deaths caused by exposure to hot and cold temperature extremes are preventable when proper measures are taken. Described in this chapter are the effects of extreme heat and extreme cold on the health of members of the public, particularly older people and young people, and workers employed in various workplace settings. The differences between heat stress and heat strain are also discussed, as are various regulations governing exposure to temperature extremes. The nature and magnitude of heat- and cold-related conditions and symptoms are described in detail. Final sections of the chapter address various assessment and evaluation tools as well as prevention and control measures. In addition, an appendix describes the hazards related to hyperbaric and hypobaric environments and adverse health effects.
