Antimicrobial Activity of Marine Sponge Clathria indica (Dendy, 1889)
(Pleiades Publishing, 2011)Sponges are sessile filter feeders that have developed efficient defense mechanisms against foreign invaders such as viruses, bacteria or eukaryotic organisms. Antimicrobial peptides are known as major components of the ... -
Recruitment of mud clam Polymesoda erosa (Solander, 1876) in a mangrove habitat of Chorao Island, Goa
(Universidade de São Paulo, Instituto Oceanográfico, 2011)Habitat-specific settlement success results either from active habitat selection or differential mortality after non-selective settlement. The mud clam Polymesoda erosa (Solander, 1876) is an ecologically and economically ... -
Maritime archaeological studies in India
(Oxford, 2011)India with more than 7000 km long coastline and about 5000 years old maritime history is dotted with several ancient ports. Marine archaeological research during last two and half decades has revealed a number of sites ... -
Ocean, Spreading Centre
(Springer, 2011)A midocean ridge, an underwater mountainous feature, extends for a length of about 65,000 km as a single continuous body in the global oceans. It is a window to the Earth's interior, through which magma is continuously ... -
A multi-method approach for the study of lanthanum speciation in coastal and estuarine sediments
(Elsevier, 2011)Two independent analytical methods (sequential extraction and kinetic extraction methods) were applied in order to understand the distribution and speciation of La in the coastal and estuarine sediments from the central ... -
Screening marine organisms for antimicrobial activity against clinical pathogens
(NISCAIR (CSIR), 2011)Bacterial resistance to existing antibiotics has led to the search for new therapeutic agents. With this aim, we have evaluated antimicrobial activity of extracts prepared from forty species of marine organisms belonging ... -
Objective mapping of observed sub-surface mesoscale cold core eddy in the Bay of Bengal by stochastic inverse technique with tomographically simulated travel times
(NISCAIR (CSIR), 2011)Present study consists the acoustic characteristics of a sub-surface cold core eddy observed (below the mixed layer between depths of 50 and 300m, with a diameter of about 200 km having temperature drop of 5 Degree Celsius ... -
Fine-scale responses of phytoplankton to freshwater influx in a tropical monsoonal estuary following the onset of southwest monsoon
(Indian Academy of Sciences, 2011)In May of 2007, a study was initiated by the National Institute of Oceanography (NIO), Goa, India, to investigate the influence of monsoonal rainfall on hydrographic conditions in the Mandovi River of India. The study was ... -
Reconstruction of Antarctic climate change using ice core proxy records from the coastal Dronning Maud Land, East Antarctica
(Geological Society of India, 2011)Antarctic ice core records have provided unprecedented information on past climatic changes and forcing factors on decadal to millennial timescales. The glaciochemical and stable isotope records of a shallow ice core from ... -
Assessing the effect of leachate of copper slag from the ISASMELT process on cell growth and proximate components in microalgae, Chlorella vulgaris (Beijerinck)
(Taylor & Francis, 2011)Dumping or disposal of huge quantities of slag (containing significant amounts of heavy metals) generated during matte smelting and refining of copper (Cu) is likely to result in environmental toxicity. Detailed chemical ... -
Measurement and modeling of bed shear stress under solitary waves
(Elsevier, 2011)Direct measurements of bed shear stresses (using a shear cell apparatus) generated by non-breaking solitary waves are presented. The measurements were carried out over a smooth bed in laminar and transitional flow regimes ... -
Biosynthesis, asymmetric synthesis, and pharmacology, including cellular targets, of the pyrrole-2-aminoimidazole marine alkaloids
(The Royal Society of Chemistry, 2011)The pyrrole-2-aminoimidazole (P-2-AI) alkaloids are a growing family of marine alkaloids, now numbering well over 150 members, with high topographical and biological information content. Their intriguing structural complexity, ... -
Distribution of putative virulence genes and antimicrobial drug resistance in Vibrio harveyi
(Springer, 2011)The marine-estuarine bacterium Vibrio harveyi is an important pathogen of invertebrates, most significantly, the larvae of commercially important shrimp Penaeus monodon. In this study, we analyzed V. harveyi isolated from ... -
Role of alkaline-tolerant fungal cellulases in release of total antioxidants from agro-wastes under solid state fermentation
(North Carolina State University, 2011)The alkaline-tolerant marine-derived fungus Chaetomium globosum was tested for the production of enhanced levels of cellulases and free phenolics under highly alkaline conditions using agro wastes (cotton seed, sugar cane ... -
Role of conspecific cues and sugars in the settlement of cyprids of the barnacle, Balanus amphitrite
(The Zoological Society of London, 2011)Gregarious settlement in barnacle is attributed to the settlement-inducing protein complex of cuticular glycoprotein, arthropodin. In this study, we characterized arthropodin protein complex (APC) from crude protein extracts ... -
Ocean iron fertilization
(TERI Press, 2011)In 2009 and 2010, an Indo-German scientific expedition dusted the ocean with iron to stimulate the biological pump that captures atmosphereic carbon dioxide. Two onboard scientists tell the story of this controversial ... -
Distribution and abundance of macrobenthic polychaetes along the South Indian coast
(Springer, 2011)Macrobenthic polychaetes play a significant role in marine benthic food chain. A study was carried out to observe the abundance and diversity of soft bottom macrobenthic polychaetes along the South Indian coast, along with ... -
Reactivity studies of eta sup (6)-p-cymene ruthenium(II) carboxylato complexes towards azide some neutral ligands
(The Indian Chemical Society, 2011)Mono and di-nuclear eta sup (6)-p-cymene ruthenium(II) complexes containing carboxylato ligand of formulation [(eta sup (6)-p-cymene)Ru(pa)Cl] and [{(eta sup (6)-p-cymene)RuCl}2 (mu-LL)] [where, pa = O sub (2)CC sub (6)H ... -
Wave transformation at select locations along the Indian coast through measurements, modelling and remote sensing
(2010)Influence of sea breeze on wind sea generation along the west coast of India is dominant during premonsoon season. The superimposition of these wind seas with pre-existing swells results in complex sea states, which makes ... -
