Seawater intrusion promotes the salinity of groundwater, and it poses a great environmental impact on a global scale. The present study was carried out to determine the hydrogeochemical processes and influence of seawater intrusion in the coastal aquifers using geophysical, geochemical, and stable isotope techniques. The true resistivity value ranges from 0.5 to 8008.5 Ω-m which has been measured using vertical electrical sounding (VES) based on the Schlumberger method. About 33 groundwater samples were collected during post-monsoon (POM) (January 2012) and pre-monsoon (PRM) (June 2012) seasons from open and bore wells and were analyzed for major ions and stable isotopes...

INTRODUCTION: The anatomy of the cochlea forms the basis for a successful cochlear implantation. Cochlear duct length (CDL) is defined as the length of the scala media as measured from the middle of the round window to helicotrema. Preoperative measurement of CDL is particularly important when precise intracochlear electrode array placement is desired. It can be done both histologically and radiologically. Preoperative high-resolution computed tomography (HRCT) scan which forms an integral part of cochlear implant workup is a useful tool to calculate CDL using 3D reconstructions...

Attitudinal differences toward wildlife have important implications for conflict management and when the species in question have strong cultural and religious associations, conflict mitigation becomes a challenging endeavor. We investigated farmers' attitudes toward two different crop-raiding macaque species, the rhesus macaque in northern India, and the bonnet macaque in southern India. Apart from regional differences in attitudes, we also assessed temporal changes in attitude toward the rhesus macaque. We carried out household surveys using a semistructured questionnaire to collect data...

A SIR epidemic model is analyzed with respect to identification of its parameters, based upon reported case data from public health sources. The objective of the analysis is to understand the relation of unreported cases to reported cases. In many epidemic diseases the ratio of unreported to reported cases is very high, and of major importance in implementing measures for controlling the epidemic. This ratio can be estimated by the identification of parameters for the model from reported case data. The analysis is applied to three examples: (1) the Hong Kong seasonal influenza epidemic in New York City in 1968-1969, (2) the bubonic plague epidemic in Bombay, India in 1906, and (3) the seasonal influenza epidemic in Puerto Rico in 2016-2017...

On 17 February 1968, Bombay surgeon Prafulla Kumar Sen transplanted a human heart, becoming the fourth surgeon in the world to attempt the feat. Even though the patient survived just three hours, the feat won Sen worldwide acclaim. The ability of Sen's team to join the ranks of the world's surgical pioneers raises interesting questions. How was Sen able to transplant so quickly? He had to train a team of collaborators, import or reverse engineer technologies and techniques that had been developed largely in the United States, and begin conversations with Indian political authorities about the contested concept of brain death...

Passenger modes in India include walking, cycling, buses, trains, intermediate public transport modes (IPT) such as three-wheeled auto rickshaws or tuk-tuks, motorised two-wheelers (2W) as well as cars. However, epidemiological studies of traffic crashes in India have been limited in their approach to account for the exposure of these road users. In 2011, for the first time, census in India reported travel distance and mode of travel for workers. A Poisson-lognormal mixture regression model is developed at the state level to explore the relationship of road deaths of all the road users with commute travel distance by different on-road modes...

Tobacco use is one of the main preventable causes of mortality and morbidity worldwide. The global disease burden due to tobacco use is huge with projected mortality of eight million lives per year by 2030. Metabolic syndrome (MS) is defined as a constellation of cardiovascular and endocrine risk factors such as insulin resistance, obesity, raised blood pressure, and abnormal lipid profile. The relationship between tobacco use and MS has been well established. Also, the causal association between tobacco use and development of individual components of MS is well established...
