Stopping manoeuvre of high speed vessels fitted with screw and waterjet propulsion

Concern about the increase in high-speed vessel traffic necessitates steps to bring out safety guidelines in order to regulate and improve their manoeuvrability. The stopping abilities of vessels ranging from medium speed containerships to high-speed vessels have been estimated. Assuming a straight contour track, the stopping distances have been checked against the known stopping criteria of IM

Determinants of current ratios: a study with reference to companies listed in Bombay stock exchange

Current ratio measures the liquidity and margin of safety that companies maintain in order to allow for the inevitable unevenness in the flow of funds. The present study examines the trend and determinants of current ratios of listed companies in India using panel least square with fixed and random effect. The analysis is based on data collected from 219 companies of Bombay Stock Exchange 500 index. The study evaluated the determinants of current ratios and trend in sector wise as well as sample taken as a whole. The result of the study shows current ratio is showing a negative trend in last decade. Receivable days, payable days, inventory days and size of the firm are the major determinant of current ratio. Inventory turnover does not have any impact for determine current ratioKey words: current ratio, liquidity, panel least square, inventory turnover, receivable days

Consumers’ Perception regarding Service Quality in Aviation Sector in Agartala

This paper intend to identify the factors affecting the consumer perception (when people chooses the services by compulsion not by choice) regarding the service quality among three domestic airlines namely Spice Jet, Indigo and Kingfisher, service providers in Agartala and to identify the most important factor in case of each domestic airlines. For achieving this objective a questionnaire was framed according to SERVPERF model and data from 110 subjects. Factor analysis and then regression analysis was carried out for extracting the factors and identifying the most important factor. We found that among the three airline service providers the number of factors loaded is different. Additionally, in case of Spice Jet and Indigo ‘assurance’ and in case of Kingfisher ‘safe and promptness’ factor is found to be most important factor

Textural evolution and phase transformation in titania membranes: Part 1. -unsupported membranes

Textural evolution in sol–gel derived nanostructured unsupported titania membranes has been studied using differential scanning calorimetry (DSC), differential thermal analysis (DTA), thermal gravimetry (TG), X-ray diffraction (XRD) and N2 adsorption. The anatase-to-rutile phase transformation kinetics were studied using the Avrami model. The precursor gel had a surface area of ca. 165 m2 g–1, which after heat treatment at 600 °C for 8 h reduced to zero. Undoped titania-gel layers transformed to more than 95% rutile after calcination at 600 °C for 8 h. The causes of surface-area reduction and pore growth were anatase crystallite growth and the enhanced sintering of rutile during transformation. Lanthanum oxide was identified as a suitable dopant for shifting the transformation temperature to ca. 850 °C. Lanthanum oxide doped titania showed an improved stability of porous texture compared to that of the undoped titania membranes

Lipoprotein-Associated Phospholipase A2, Vascular Inflammation and Cardiovascular Risk Prediction

Circulating lipoprotein-associated phospholipase A2 (Lp-PLA2) is a marker of inflammation that plays a critical role in atherogenesis; its inhibition may have antiatherogenic effects. Studies from the West of Scotland Coronary Prevention Study (WOSCOPS), Monitoring Trends and Determinants in Cardiovascular Diseases (MONICA) and Rotterdam cohorts have shown that Lp-PLA2 is an independent predictor of coronary heart disease (CHD), and the association is not attenuated upon multivariate analysis with traditional risk factors and other inflammatory markers. Studies in subjects with coronary artery disease (CAD) have also shown associations between Lp-PLA2 and cardiovascular risk. At least two recent studies have shown that Lp-PLA2 is a risk predictor for stroke. Overall, epidemiological studies suggest that measurement of Lp-PLA2 in plasma may be a useful in identifying individuals at high risk for cardiovascular events

Separation and Staging Mechanisms for the Indian SLV-3 Launch Vehicle

A unique separation and jettison system for the ascent fairing and a staging system for the apogee motor of the first Indian satellite launch vehicle are described. Design features, development problems, and mission constraints are discussed in addition to the solutions adopted. A qualification summary is included for each system, and flight results obtained from SLV-3 launches are described
