Solar variability and global climate change
Title: Solar variability and global climate change
Authors: Dubey, S.C.
Abstract: Present study consists
solar influence on global climate change, including the physics of solar
variability. Climate change is a long-term change in the weather patterns over
periods of time that may range from decades to thousands of years. The basic
components that influence the Earth’s climatic system can occur externally
(from extraterrestrial systems) and internally (from ocean, atmosphere and land
systems). Total solar irradiance (TSI) has been monitored continuously from
space since 1977. Long-term solar irradiance variations might contribute to
global warming over decades or hundreds of years. According to TSI variation
trends in recent decades, the Sun has contributed a slight cooling influence
but our globe is warmed up continuously. It is indication for a dangerous
period and high awareness about global warming is
most essential. Adverse
impact of climate change and global warming in our ecosystems and challenges in
near future along-with perspective role of solar influences in recent climate
change have been discussed in the present study.
Biodegradation of diesel using microbes from a clam (Meretrixmeretrix) shell
Title: Biodegradation of diesel using microbes from a clam (Meretrixmeretrix) shell
Authors: Mhatre, B A.; Kunde, R.
Abstract: Present study consists
the potential ability of microorganisms present on clam (Meretrixmeretrix)
shells to degrade diesel. Counts of crude oil degrading bacteria in oil
polluted soil fortified with Meretrixmeretrix shells were higher than
that of unfortified soil. Microorganism isolated from the Meretrixmeretrix shells
was found to be Bacillus subtilis, which is seen to have potent lipase
activity, thus capable of degrading diesel and releasing carbon dioxide. This
study show that
shells efficiently degrade diesel and can help in bioremediation of oil
Occurrence of Vibrio parahaemolyticus in marine fish and shellfish
Title: Occurrence of Vibrio parahaemolyticus in marine fish and shellfish
Authors: Anjay; Das, S.C.; Kumar, A.; Kaushik, P.; Kurmi, B.
Abstract: Vibrio parahaemolyticus is a marine
bacterium that causes seafood borne gastroenteritis and traveler’s diarrhea in
humans, after consumption of contaminated raw or partially cooked fish or shell
fish. In this study a total of 224 marine fish and shellfish samples were
screened that included 34 of Bhetki (Lates calcarifer), 40 of Parse (Liza
parsia), 40 of Pabda (Ompok pabda), 30 of Pomfret (Pampus
chinensis), 38 of Lote fish (Harpodon nehereus) and 42 of Tiger
prawn (Penaeus monodon). V. parahaemolyticus was identified by
biochemical characterization and polymerase chain reaction (PCR) targeting the toxR
gene. Out of 224 samples, V. parahaemolyticus could be isolated and
biochemically characterized from 170 (75.9 %) samples including L.
calcarifer 31 (91.2%), L. parsia 28 (70.0%), O. pabda 30
(75.0%), P. chinensis 22 (73.3%), H. nehereus 28 (73.7%) and P.
monodon 31 (73.8%). All the positive isolates were further confirmed by PCR
amplification of target gene, toxR.
