Abstract

Wave fields, both measured and forecast during the very severe cyclone Phailin, are discussed in this communication. Waves having maximum height of 13.54 m were recorded at Gopalpur, the landfall point of the cyclone. The forecast and observed significant wave heights matched well at Gopalpur with correlation coefficient of 0.98, RMS e rror of 0.35 m and scatter index of 14%. Forecasts were also validated in the open ocean and found to be reliable (scatter index < 15%). The study also revealed the presence of Southern Ocean swells with a peak period of 20-22 sec hitting Gopalpur coast along with the cyclone-generated waves.

Abstract

Personal hygiene is the process of maintaining cleanliness. Failure to maintain adequate personal hygiene can result in illnesses of all kinds. Poor hand-washing practices increase the likelihood of contracting contagious illnesses such as influenza and food-borne illnesses like Salmonella infection. Multipurpose herbal wash is expected to be proven more economical compared to conventional products as the customer may get the desired effect by buying one container of bodywash which can act as a shampoo also. Formulated herbal wash preparations were evaluated for physical parameters like colour, fragrance and chemical parameters like pH, percent of solids contents, viscosity, surface tension, dirt dispersion, cleaning action, foaming ability and foam stability, antimicrobial activity, anti fungal activity and results shown that all were in the accepted limits. Combination of neem and tulsi was found to be effective, easier to produce stable herbal wash formulation. It is having good foaming characters and anti bacterial as well as anti fungal activity. So it can be suitable for both skin and hair care compared to other synthetic preparations.

Abstract

For present population ragi is the major food as it is considered as the power house of health benefits. The production of ragi is coming down slowly due to the climatic factors like temperature and drought. Breeding of selected genotypes with increased thermotolerance is therefore, one of the most vital objective in crop improvement programme. Temperature induction response (TIR) technique has been developed to identify thermotolerant lines. 24 ragi genotypes has been tested using temperature induction response (TIR) technique. Ragi seedlings were exposed to gradual increase in temperature range of 32-48°C for 5hrs and later subjected to the lethal temperature of 54°C for 2 hrs. These treated seedlings were allowed to recover at 30°C and 60% relative humidity for 2 days. After recovery per cent survival, per cent reduction of ischolar_main growth and per cent reduction of shoot growth was calculated. Among 24 ragi genotypes VR900, Indaf 8 and Udurumalliga were found resistant with low per cent reduction of ischolar_main and shoot growth and the genotypes VR 1138, CO-7 and OUAT-2 were found susceptible with high per cent reduction of ischolar_main and shoot growth. By using this TIR technique it is easy to identify thermotolerant lines from a large range of population at the seedling level itself.

Abstract

A simple, Robust, stability indicated method was developed for the estimation of Abiraterone by RP-UPLC technique. Chromatographic conditions used are, stationary phase SB C8 100 x 3.0 mm, 1.8. Mobile phase 0.01N NaH₂PO₄: Acetonitrile in the ratio of 60:40v/v and flow rate were maintained at 0.3 ml/min, detection wave length was 235 nm, and column temperature was set to 30^oC. System suitability parameters were studied by injecting the standard six times and results were well under the acceptance criteria. Linearity study was carried out between 25% to150 % levels, R² value was found to be as 0.999. Precision was found to be 0.6 for repeatability and 1.1 for intermediate precision. LOD and LOQ are 0.09μg/ml and 0.27μg/ml respectively. Degradation studies of Abiraterone were done, in all conditions and it is within the acceptable range.

Abstract

Wave-power generation could be a feasible solution to the huge power requirements of a country like India having a long coastline. The present study provides details of wave characteristics and wave power potential during different seasons along the Indian coast using wave observations. Seasonal average of significant wave height (Hs) was computed near the coastal areas of India from the measured data. Hs varied in the range 1.62–1.95 m and 1.38–1.39 m along the west and east coastal areas respectively, during summer monsoon. These high waves generate high wave power (>20 kW/m) along the east and west coastal areas of India. The seasonal average of wave power obtained was high (12–19 kW/m) off the west coast of India, suggesting that the west coastal areas are suitable for power generation during summer monsoon. This study highlights that the average wave power is high (12–19 kW/m) during summer monsoon along the west coast and insignificant (<2 kW/m) during non-monsoon. Thus the present study suggests employing a to hybrid arrangement of power generation using solar and ocean wave energies to solve the problem of energy deficit near the coastal areas of India.
