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

Development of a Scale to Measure the Marketing Behaviour of Vegetable Farmers

Marketing behaviour is the attitude and/or conduct of a person towards marketing activities. Marketing decisions made by the farmer are based on factors such as commodity, quantity and quality of produce, distance from market, transportation facilities, risk bearing ability, innovativeness, etc. The study of marketing behaviour of the farmer could help in promoting inclusive markets with the direct participation of farmers leading to better profit margins. In the present study a scale was developed to measure the marketing behaviour of vegetable farmers. The items generated rated for relevance by expert judges and after item selection; it was administered to respondents for scoring. This was followed by factor analysis using principal component analysis. The scale was standardized after reliability testing using Cronbach's alpha and scale validation using content analysis. The final scale covered seven dimensions, viz., production oriented decisions, planning orientation, farm enterprise management, enterprise planning, technology oriented marketing, market based production preferences and quality oriented production with 27 statements

Stakeholder Analysis for Farmer- inclusive Value chain Development in Mango

Mango is being cultivated over a substantial area in Palakkad District of Kerala state. Being one of the significant agricultural commodity value chains existing in Kerala, the mango value chain of Palakkad district needs urgent attention to improve its performance. The study highlights the stakeholder analysis and SWOC matrix analysis of the mango sector. Stakeholders were asked to identify the strengths, weaknesses, opportunities and challenges in the mango sector. Based on the highest score obtained, four strategic options viz., enhancing value addition and product development, promotion of branding, educating the farmers on building competitiveness and increasing export potential by addressing quality parameters were identified

1-Naphthylazo derivatives of some 1,3-dicarbonyl compounds and their Cu(II), Ni(II) and Zn(II) complexes

The coupling of diazotized 1-aminonaphthalene with 1,3-dicarbonyl compounds (acetylacetone, methylacetoacetate and acetoacetanilide) yielded a new series of bidentate ligand systems (HL). Analytical, IR, 1H-NMR and mass spectral data indicate that the compounds exist in the intramolecularly hydrogen bonded keto-hydrazone form. With Ni(II), Cu(II) and Zn(II), these potential monobasic bidentate ligands formed [ML2] type complexes. The IR, 1H-NMR and mass spectral data of the complexes are consistent with the replacement of the chelated hydrazone proton of the ligand by a metal ion, thus leading to a stable six-membered chelate ring involving the hydrazone nitrogen and the hydrogen bonded carbonyl oxygen. The Ni(II) and Zn(II) chelates are diamagnetic, while the Cu(II) complexes are paramagnetic. In the metal complexes of the naphthylazo derivatives of acetylacetone and methylacetoacetate, the acetyl carbonyl is involved in coordination, whereas in the chelates of the naphthylazo derivative of acetoacetanilide, the anilide carbonyl is bonded with the metal ion

An Appraisal of the Marine Fisheries of Karnataka and Goa

Karnataka, on the West coast, plays an important role in the fisheries development of India and has a prominent place in the country's fisheries map, It has a shelf area of 25000 Sq. Km. and a coastline of 270 Km, about 1/22 of the country's coastline. The State's contribution to the total marine fish production in the country is of the order of ^.0%. The State has two coastal districts, namely Dakshin Kannada and Uttar Kannada. The lengths of coastline of both the districts are almost the same. Many rivers such as the Nethravathi, the Saravathi and the Kali flow into the Arabian sea and render the inshore area rich in nutrients

Bioactive extract of mycelia biomass of Ganoderma lucidum protects doxorubicin induced cardiomyopathy

Cardiotoxicity induced by anticancer drug; doxorubicin (DOX) is a limiting factor for its prolonged use in chemotherapy. No effective drug is currently available to prevent DOX induced cardiomyopathy. Ganoderma lucidum is highly valued medicinal mushroom used in traditional medicine. Mycelia biomasses are considered as alternate sources of mushroom bioactive compounds. We examined the effect of bioactive extract of G. lucidum mycelia biomass (GLME) to prevent cardiotoxicity induced by DOX in rats using a cumulative dose 18 mg/kg body wt. GLME was administered to animals at doses of 250 and 500 mg/kg body wt. once daily for five days prior to DOX administration and continued for three more days. Animals were sacrificed 24 h after the last dose of drug. Activities of creatine kinase (CK), lactate dehydrogenase (LDH), endogenous antioxidant status, oxidative stress markers, electrocardiograph (ECG) and haematological parameters were evaluated. DOX administration drastically elevated CK, LDH, myocardial peroxidation and oxidative stress and significantly lowered endogenous antioxidant activity. GLME administration attenuated elevated levels of CK, LDH and oxidative stress and also ameliorated alterations in haematological and ECG parameters. Results revealed that bioactive extract of G. lucidum mycelia imparted significant protection against DOX induced cardiomyopathy suggesting the potential therapeutic significance of G. lucidum mycelia bioactives to alleviate DOX induced cardiomyopathy
