    Opis:
    Objective. We examined the personality correlates of accident-proneness of auto-rickshaw drivers in the Indian city of Ranchi. Methods. This was a cross-sectional study in which 50 male drivers aged 18-50 years, selected randomly from a list of licensed auto-rickshaw drivers in Ranchi, were assessed with a Hindi version of Cattell's 16 Personality Factors (l6-PF) Questionnaire. Results. There was a significantly higher frequency of breaking rules, crossing speed limits, substance use and a trend towards a higher frequency of carrying extra persons (i.e., more than recommended) in accident-prone drivers. There was significant negative correlation of accident-proneness with 16-PF factors such as reasoning, rule consciousness, apprehension and emotional stability. Conclusion. Personality characteristics with lower scores of reasoning, rule consciousness, apprehension and emotional stability are common in commercial auto-rickshaw drivers with high accident-proneness.

    Opis:
    The increasing industrialization and development in the field of transport sector of the world have led to a steep rise for the demand of petroleum products. Petroleum fuels are obtained from limited reserves of foreign countries. Presently our country is facing the problem of foreign exchange due to the import of crude oil. Hence, it is necessary to look for alternative fuel, which can be produced from available raw material within the country. In the present investigation, the bio-diesel produced from the jatropha seeds have been considered as a potential alternative for running the compression ignition engines. The different blends of bio-diesel and conventional diesel have been tested on the engine. The experimental data obtained for various concentrations of bio-diesel blends have been compared with base line data of conventional diesel. Significant improvement in engine performance has been observed due to the use of bio-diesel. Acceptable thermal efficiencies of the engine have been obtained with different blends of bio-diesel and diesel. It has been observed that 20% of jatropha oil can be substituted for diesel without any engine modification and preheating of the blends.

    Opis:
    A plastic bonded explosive (PBX) in the form of a sheet explosive was formulated with 1,3,5-trinitro-1,3,5-triazinane (RDX) dispersed in a polymeric matrix of a thermoplastic linear polyurethane and a 50/50 wt.% eutectic mixture of energetic plasticizers, viz., bis(2,2-dinitropropyl)formal (BDNPF) and bis(2,2-dinitropropyl)acetal (BDNPA) was used to increase the performance of the sheet explosive in terms of its velocity of detonation (VOD). The sheet explosives were prepared by a rolling process. Natural rubber (ISNR-5) based sheet explosive was taken as the standard composition. The study showed that the BDNPF/A based sheet explosive has a velocity of detonation of 7850 m/s, which is about 900 m/s higher than the standard composition. Thermal analysis of the sheet explosive formulations was performed using differential scanning calorimetry (DSC).

    Opis:
    The paper describes the noise monitoring data acquired from the pilot project on the establishment of National Ambient Noise Monitoring Network (NANMN) across seven major cities in India for continuous noise monitoring throughout the year. The annual average Lday (06–22 h) and Lnight (22–06 h) values observed in year 2011–2014 for the 35 locations under study in which 14 locations are in commercial zone, 5 in Industrial, 7 in residential and 9 in silence zones are described. The long-term noise monitoring shows that ambient noise levels have marginally increased for 29 sites (82.9%) since past four years. The present study is focused on evaluation and analysis of environmental noise pollution at 35 noise monitoring sites in seven major cities of India and shall be instrumental in planning for the noise abatement measures for controlling the noise pollution in these sites.

    Opis:
    In the present paper, 2,4-dinitroanisole (DNAN) has been evaluated as a melt cast explosive in comparison to the widely used 2,4,6-trinitrotoluene (TNT). The detonation failure diameter of a bare DNAN charge is greater than 100 mm and about 44 mm with 1.5 mm steel confinement. Comparative studies of two sets of formulations were carried out. The first set comprised formulations containing 60% of NTO, FOX-7, HMX or RDX and 40% of DNAN or TNT. The second set comprised formulations containing 30% of NTO, FOX-7, TATB or RDX and 70% of DNAN or TNT. The studies were mainly concentrated on characterization of the formulations, which included determination of the sensitivity parameters and the velocity of detonation (VOD). The study confirmed that DNAN and DNAN-based formulations are relatively insensitive compared to TNT and the analogous TNT-based formulations respectively. The rate of the detonation reaction of DNAN is enhanced in the presence of the high energy ingredients RDX, HMX, FOX-7 and NTO to varying degrees. The VODs of the FOX-7/TNT and RDX/TNT formulations match closely with the proportions of FOX-7 and RDX under study. The VOD and shock sensitivity of the FOX-7/DNAN formulations decrease rapidly compared to the RDX/DNAN formulations, with increases in the proportion of FOX-7 or RDX. The combinations of NTO with TNT, and NTO with DNAN, are more shock insensitive than TNT or DNAN alone. NTO-based compositions are more insensitive than FOX-7-based compositions.
