Opisthorchis viverrini: Detection by polymerase chain reaction (PCR) in human stool samples
(Elsevier, 2008)A polymerase chain reaction (PCR) assay was evaluated for detection of Opisthorchis viverrini eggs in the stool specimens of light and heavily infected individuals in Khon Kaen province of Thailand. A total of 75 fecal ... -
Bacterial production, glucosidase activity and particle-associated carbohydrates in Dona Paula bay, west coast of India
(Elsevier, 2008)Size-fractionated bacterial production, abundance and Alpha - and Beta - glucosidase enzyme activities were studied with respect to changes in hydrography, total suspended matter (TSM), chlorophyll a, particulate organic ... -
Use of Fourier Transform Infrared (FTIR) spectroscopy to study cadmium-induced changes in Padina tetrastromatica (Hauck)
(Libertas Academica, 2008)The aim of this study is to adopt the approach of metabolic fingerprinting through the use of Fourier Transform Infrared (FTIR) technique to understand changes in the chemical structure in Padina tetrastromatica (Hauck). ... -
Investigation of a method for predicting AUV derivatives
(Elsevier, 2008)The paper addresses the problem of autonomous underwater vehicle (AUV) modelling and parameter estimation as a means to predict the dynamic performance of underwater vehicles and thus provide solid guidelines during their ... -
Variability in biological responses influenced by upwelling events in the Eastern Arabian Sea
(Elsevier, 2008)This study documents the result of field observations from the southeastern Arabian Sea during onset, peak and late phases of summer monsoon. The pronounced variations in phytoplankton standing stock (chlorophyll a), primary ... -
Observational evidence for remote forcing of the west India coastal current
(American Geophysical Union, 2008)Circulation in the north Indian Ocean is influenced by both local and remote wind forcing. So far, however, determining the contribution of these two forcing mechanisms at a location has been possible only in numerical ... -
Anti-plagiarism certification be an academic mandate
(American Society for Information Science and Technology, 2008)The analysis from 4,000 odd pages taken from various search engines, for measuring the document similarity depicted interesting results. Two keywords were presented to the documents and calculated the number of such ... -
Growth and proximate composition of the Chaetoceros calcitrans f. pumilus under different temperature, salinity and carbon dioxide levels
(Blackwell Publishing, 2008)The marine diatom Chaetoceros calcitrans f. pumilus has been examined for its potential source as live feed in aquaculture. The present study investigated eíects of temperature (20,25 and 30 degrees C), salinity (25 and ... -
Structure and isostatic compensation of the Comorin Ridge, north central Indian Ocean
(Royal Astronomical Society, 2008)Bathymetry, gravity and magnetic data (about 9200 l km) of the Comorin Ridge, north central Indian Ocean were investigated using the transfer function and forward model techniques to understand the mode of isostatic ... -
Integrated coastal area management: The case of India
(Capital Publishing, 2008)Typical developing nations like India have accelerated activities in the field of industries, shipping, ports, fishing, mining, urbanisation and tourism. All these affect the coastal areas. Coastal zone takes the brunt of ... -
Abiogenic origin of petroleum hydrocarbons: Need to rethink exploration strategies
(Current Science Association, 2008)The origin of petroleum hydrocarbons is a matter of debate since its discovery. During last several decades it is firmly believed that the origin of petroleum hydrocarbons is 'biogenic' due to chemical similarity between ... -
Marine-derived fungi as a source of proteases
(NISCAIR, CSIR, 2008)Microbial enzymes have continued to assist diverse reactions as biocatalysts. Marine derived microbes offer a prospective resource for such enzymes. In this study thirteen fungi were isolated from marine organisms (soft ... -
Spatial variations in time-integrated plankton metabolic rates in Sagami Bay using triple oxygen isotopes and O2:Ar ratios
(American Society of Limnology and Oceanography, 2008)Plankton metabolic rates, such as rates of gross, net community production and community respiration, were measured in the surface waters using triple oxygen isotopes and O2 : Ar ratios. The 17 delta anomaly showed clear ... -
Veeravalli Venkata Ranga Varadachari (01 July 1925- 04 August 2007)
(INSA, 2008)The extent of the involvement of VVR in the multi-disciplinary research activities concerning physical oceanography individually and in collaboration with his research students and associates at the institutional level ... -
First evidence of tumor-like anomaly infestation in Copepods from the central Indian Ridge
(NISCAIR, CSIR, 2008)To investigate the distribution and abundance of mesozooplankton in the Indian Ocean, zooplankton sampling was conducted along the Central Indian Ridge (CIR) from the equatorial waters to 8 degrees S latitude. Of the seven ... -
Enhancement of vertebrate cardiogenesis by a lectin from perivitelline fluid of horseshoe crab embryo
(Birkhäuser Basel, 2008)Cardiac myocytes are the first cells to differentiate during the development of a vertebrate embryo. A wide variety of molecules take part in various steps in this process. While exploring biologically active molecules ... -
Recently studied sedimentary records from the eastern Arabian Sea: Implications to Holocene monsoonal variability
(The Society of Earth Scientists, 2008)Deep insight into exact mechanism(s) controlling past monsoonal variability on inter-annual to millennial time scales is a pre-requisite for developing predictive capability of monsoon on timescales relevant to human life. ... -
