Analysis of non-pharmaceutical interventions and their impacts on COVID-19 in Kerala.

In the absence of an effective vaccine or drug therapy, non-pharmaceutical interventions are the only option for control of the outbreak of the coronavirus disease 2019, a pandemic with global implications. Each of the over 200 countries affected has followed its own path in dealing with the crisis, making it difficult to evaluate the effectiveness of measures implemented, either individually, or collectively. In this paper we analyse the case of the south Indian state of Kerala, which received much attention in the international media for its actions in containing the spread of the disease in the early months of the pandemic, but later succumbed to a second wave.

Differential bleaching of corals based on El Niño type and intensity in the Andaman Sea, southeast Bay of Bengal.

The Andaman coral reef region experienced mass bleaching events during 1998 and 2010. The purpose of this study is to investigate the role of the El Niño in the coral reef bleaching events of the Andaman region. Both Niño 3.

Impact of Coastal Pollution on Microbial and Mineral Profile of Edible Oyster (Crassostrea rivularis) in the Coastal Waters of Andaman.

The impact of coastal pollution was studied using edible oysters, Crassostrea rivularis as an indicator at two sites viz., North Wandoor (NW) and Phoenix Jetty (PJ) in Port Blair, Andaman. The hydrographic parameters showed that nitrite, nitrate and phosphate concentration were less and dissolved oxygen were more at NW compared to PJ.

Effect of sub-lethal concentration of endosulfan on lipid and fatty acid metabolism of spotted murrel, Channa punctatus.

The spotted murrel, Channa punctatuswere exposed to sub-lethal concentration of endosulfan (8.1 microg l(-1)) for 12, 24, 48, 72 and 96 hrto elucidate the impact of pesticide on fatty acid composition of liver and muscle. After endosulfan exposure, fish from each control and experimental tanks were randomly sampled anesthetized, sacrificed and then the liver and muscle were dissected out for lipid and fatty acid (FA) profile.

Tropical storm off Myanmar coast sweeps reefs in Ritchie's Archipelago, Andaman.

The reefs in some islands of Andaman and Nicobar suffered severe damage following a tropical storm in the Bay of Bengal off Myanmar coast during 13-17 March 2011. Surveys were conducted at eight sites in Andaman, of which five were located in the Ritchie's Archipelago where maximum wind speeds of 11 m s(-1) was observed; and three around Port Blair which lay on the leeward side of the storm and had not experienced wind speeds of more than 9 m s(-1). Corals in the shallow inshore reefs were broken and dislodged by the thrust of the waves.
