Glutathione S-transferase, catalase, superoxide dismutase, glutathione peroxidase, and lipid peroxidation as a biomarkers of oxidative stress in snails: A review
(University of Modena and Reggio Emilia, 2016)Antioxidant defense plays a crucial role in the response of an organism to pollutants. Several processes stimulate the production of free radicals or deplete the antioxidant defense, which if not regulated properly, may ... -
Glycolipids from the red alga Chondria armata (Kutz.) Okamura
(Oxford University Press, 2006)Three distinct fractions containing polar glycolipids (PF1–3) were isolated from the chloroform soluble fraction of crude methanolic extract of red alga Chondria armata (Kütz.) Okamura on gel chromatography over Sephadex ... -

(IEEE Singapore Section Secretariat, 2006)Development and implementation of a real-time reporting and Internet-accessible sea level gauge is described. The paper addresses the application of mobile communication technology and particularly the use of General Packet ... -
Grade distributions in manganese nodules of Central Indian Ocean Basin
(Current Science Association, 1989)Data concerning to geological setting physical characteristics and bulk chemical composition of the nodules sampled from CIOB were stored in the Computer Data Bank of this Institute. Bulk chemical composition of nodules, ... -
Grain size analysis of sediments from the northern Andaman Sea: Comparison of laser diffraction and sieve-pipette techniques
(Coastal Education and Reserch Foundation, 2006)A comparison has been made of sand, silt, and clay percentage of 118 samples from the Ayeyarwady continental shelf, northern Andaman Sea, measured by the sieve-laser diffraction technique and by classical sieve-pipette ... -
Grain size distribution and annual variation along the beaches from Poompuhar to Nagoor, Tamilnadu, India
(Allied, India, 2005)Systematic sedimentological investigations have been carried out along the central coast of Tamil nadu (India) for a stretch of 35 km from Poompuhar to Nagoore. Sediment samples had been collected in Dec. 2003, 2004 and ... -
Grain size studies on the nearshore sediments of Jaigad, Ambwah and Varvada Bays, Maharashtra
(Geological Society of India, 1997)Bivariate plots of the textural parameter data suggest overlapping environments, such as river/beach to JB, beach/dune/river to AB and dune/beach to VB sediments. -
Granulometric analyses of pelites using a sedigraph: Examples from a Volcano-sedimentary environment
(Geological Society of India, 1993)This article presents granulometric data of pelites (less than 40 microns) of mixed composition from a volcano-sedimentary environment. The sedigraph serves as an useful tool in the analyses of silt-clay fraction of marine ... -
Graphic pattern of foraminiferal dominance in nearshore region of central west coast of India
(Indian Association for Limnology and Oceanography, 1979)Within the inner neritic zone (0-55 m depth) along the central west coast of India, some foraminiferal groups such as @iAmmonia, Elphidium, Trochammina, Bulimina, Bolivina, Nonion, Nonionella@@ and Florilus@@ individually ... -
Grapnel stone anchors from Saurashtra: Remnants of Indo-Arab trade on the Indian coast
(The Society for Nautical Research, 2004)Stone anchors have been used as a primary source of information on ancient navigation by marine archaeologists since long. These anchors used by ancient mariners are often noticed underwater at various places across the ... -
