    707-715Tropical cyclones are form of intense storms which are common in the Bay of Bengal (BOB) and known for their damage potential to human and natural resources especially in the coastal parts of India, Bangladesh and Myanmar. A two-way effect is prominent between BOB’s sea surface temperature (SST) and these cyclonic events. On one side, BOB’s high SST favours formation of cyclones and on the other side it itself gets affected whenever cyclone occurs. The later part along with circulation patterns has been simulated here with the help of high resolution Regional Ocean Modeling System (ROMS) for 'MALA' cyclone. Remote sensing instrument Quick Scatterometer (QuikSCAT)-derived daily wind components are used as atmospheric forcing conditions for ROMS simulations. ROMS circulation is found highly sensitive towards QuikSCAT wind forcing and reveal an anticlockwise rotation with high magnitude currents due to cyclone passage. Near surface as well as deeper isotherm and isohaline surfaces show high degree of spatial variability and overall indication of upwelling happening on near track area. It is found that mixed layer depth reduces at the storm centre due to intense upwelling but increases far away from it because of high winds. Due to intrusion of bottom high saline water and reduction of temperature, density increases from its initial value which affects water column stability from surface to even below 150 m depth

    Effect of nano materials in geopolymer concrete

    SummaryIn general, cement based concrete can be replaced by low calcium fly-ash based geopolymer concrete regarding the adverse effect of the manufacture of ordinary Portland cement on environment. Nowadays, nano technology has an important role in the field of construction industries. It has been seen that several properties of cement based concrete are affected by different nano materials. As low calcium fly-ash based geopolymer concrete is an alternate option for cement based concrete, nano materials may also have some influence on it. An experimental program has been taken up on low calcium fly-ash based M25 grade geopolymer concrete having 16 (M) concentration of activator liquid. Different percentage of nano materials viz. nano silica, carbon nano tube, titanium di-oxide were also used to investigate the effect of nano materials on geopolymer concrete. Geopolymer concrete with 1% titanium di-oxide shows appreciable improvement in compressive strength although pH remains almost same in all cases

    Design and Development of a Public Health Information Service Model for Rural Inhabitants of Balasore District of Odisha: A Case Study

    Get PDF
    Introduction: The government of India has started concentrating on developing rural health infrastructure to provide primary health care services to most of the rural population, which had been by and large remained neglected. Though the government provides healthcare facilities to rural people, they are not effectively reaching them. The purpose of the study is to explore the public health information services, which ascertain the information needs of the Balasore district's rural inhabitants, and to develop an integrated Public Health Information Service (PHIS) model for health communication that promotes public health. Methods: A survey was conducted with the help of a structured questionnaire developed to gather information regarding public health communication infrastructures and services rendered by the medical officers, rural inhabitants, and the librarians of the medical college and public libraries of the Balasore district of Odisha. Results: The authors found a situation that demands an assessment of a suitable PHIS model to fulfill the health information requirement of the rural inhabitants of the Balasore district of Odisha. Conclusion: This integrated public health information service model is conceptualized and is based on the suitability of health information exchange for rural people

    Fuzzy Clustering-Based Ensemble Approach to Predicting Indian Monsoon

    Get PDF
    Indian monsoon is an important climatic phenomenon and a global climatic marker. Both statistical and numerical prediction schemes for Indian monsoon have been widely studied in literature. Statistical schemes are mainly based on regression or neural networks. However, the variability of monsoon is significant over the years and a single model is often inadequate. Meteorologists revise their models on different years based on prevailing global climatic incidents like El-Niño. These indices often have degree of severity associated with them. In this paper, we cluster the monsoon years based on their fuzzy degree of associativity to these climatic event patterns. Next, we develop individual prediction models for the year clusters. A weighted ensemble of these individual models is used to obtain the final forecast. The proposed method performs competitively with existing forecast models
