Photocatalytic and photochemical degradation of aniline using concentrated solar radiation

The photocatalytic and photochem. degrdns. (PCD) of aniline using concd. solar radiation were studied. The photochem. reaction takes place on the surface of the catalyst material. Therefore, the adsorption behavior of aniline on the catalyst was also studied. The rates of aniline degrdn. in the case of the photocatalytic process were compared with the photochem. method. The effects of the presence of anions and cations, which are commonly present in industrial wastewaters, are reported. A plausible explanation for the anomalous behavior of HCO3- and CO32- is given. The effect of pH on the PCD of aniline was also studied

Not AvailableThe Indian frogfish distributed from East Africa and the Persian Gulf east to India and Sri Lanka is a truly marine species. Frogfish of the family Antennariidae is distinguished by the presence of three well-developed dorsal spines, laterally-directed eyes, largemouth and laterally compressed body. There are no reports of the occurrence of frogfishes in river Narmada. The present study confirms the occurrence of Indian frogfish in the Narmada estuary Gujarat, India, as the first record.ICAR-CIFR

A REVIEW PAPER ON NANO-EXPLOSIVE MATERIAL

New explosive materials (EMs) are the key to great advances in microscale energydemanding systems as actuation part, igniter, propulsion unit, and power. Nanoscale explosive materials (nEMs) particularly offer the promise of much higher energy densities, faster rate of energy release, greater stability, and more security nEMs could therefore give response to microenergetics challenges. This paper provides a some review of current research activities in nEMs for microenergetics application

Not AvailableThe present study confirmed the occurrences of Walton’s mudskipper Periophthalmus waltoni Koumans 1941 under the family Gobiidae as the first kind of record from the estuarine region of river Narmada of Gujarat, India. A total of 21 specimens were collected with the size ranging from 124 to 145 mm and from 10.7 to 26.2 g, respectively, from Jageshwar fishing sites during the monsoon period (July–September 2019). Walton’s mudskipper was reported to be found in countries like Iran, Iraq, Oman and Pakistan, but its availability in Indian waters is questionable. The present findings confirmed the occurrences of the species in the Narmada estuary, Gujarat, India drainage to the Arabian Sea.ICA

Not AvailableThe diversity of finfish in river Narmada and its tributaries in central and western India has been reviewed. We could compile a total of 196 species from both freshwater and brackish water habitats, under 14 orders, 51 families, and 126 genera. The order Cypriniformes represented the highest diversity with 78 species (i.e., 39.8%) followed by Perciformes (47 species), Siluriformes (32 species), Clupeiformes (15 species), etc. As per the IUCN Red List category, the maximum number of species are under Least Concern (129), followed by Not Evaluated (36), Near Threatened (14), Data Deficient (11), Vulnerable (4), and Endangered (2). The species Tor khudree and Tor putitora were found Endangered in the system. Out of 196 finfish species, 77 are food fishes, 33 having both ornamental and food fish value, 21 are truly ornamental value, and 31 as sports fishes. Habitat wise distribution of the fishes indicates that 79 species are truly freshwater and 3 species are truly marine, while 58 species range between freshwater and brackish water habitats, 21 between brackish water and marine habitats and 35 species range from freshwater to marine habitats. This review presents up-to-date information on finfish biodiversity of river Narmada. It will help in making appropriate conservation and management planning of fisheries in this river.Not Availabl

Not AvailableA study was carried out to investigate the macrobenthic invertebrate community structure from the river Tapti from July 2017 to January 2020. A total of 49 taxa belonging to 2 phyla, 5 class, 17 orders, 26 families, and 31 genera were recorded from 13 sites of the river Tapti. Phylum Mollusca (58%) was the most dominant group followed by Arthropoda (42%) in the community structure. The species Tarebia lineatea and Bellamya bengalensis were the most abundant among the Gastropoda, Parreysia favidens and Corbicula striatella among the Bivalvia, and Caenis sp. and Chironomus sp. and among the Insecta. The frequency and relative frequency of the species revealed that the most dominant species was Bellamya bengalensis from the class Gastropoda. The data generated in the present study will be act as baseline information and would be useful in future studies for interpretation of the health of the Tapti river.ICAR-CIFR
