Hyd-based CSIR NGRI to develop landslide, flood warning system for Himalayas

Hyderabad-based CSIR- National Geophysical Research Institute (CSIRNGRI) has launched an Environmental Seismology (ES) group to develop a landslide and early flood warning system for the Himalayan region based on real- time monitoring. CSIR – NGRI said this would enable crucial warning several hours prior, which will save precious human lives and property in the future. This also has important implications for the planning of infrastructural … Continue reading Hyd-based CSIR NGRI to develop landslide, flood warning system for Himalayas

Solar DC Cooking System, a step towards green &amp pollution free India

CSIR-CMERI on 23rd September, 2021, Taking a small step in realising the dream of a ‘Pollution-Free India’, the CSIR-CMERI has developed a Solar DC Cooking System. In the distinguished presence of Swami Somatmanandaji Maharaj, Ramakrishna Mission Ashrama, Asansol, and Tapas Banerjee, Chairman, Asansol Durgapur Development Authority, Government of West Bengal, Prof. Harish Hirani, Director, CSIR-CMERI, handed over the newly developed Solar DC Cooking System to … Continue reading Solar DC Cooking System, a step towards green &amp pollution free India

River winds and pollutant recirculation near the Manaus city

Local atmospheric recirculation flows (i.e., river winds) induced by thermal contrast between wide Amazon rivers and adjacent forests could affect pollutant dispersion, but observational platforms for investigating this possibility have been lacking. Here we collected daytime vertical profiles of meteorological variables and chemical concentrations up to 500 m with a copter-type unmanned aerial vehicle during the 2019 dry season. Cluster analysis showed that a river-forest recirculation … Continue reading River winds and pollutant recirculation near the Manaus city

UAV reveals substantial but heterogeneous effects

Understanding how herbivores shape plant biomass and distribution is a core challenge in ecology. Yet, the lack of suitable remote sensing technology limits our knowledge of temporal and spatial impacts of mammal herbivores in the Earth system. The regular interannual density fluctuations of voles and lemmings are exceptional with their large reduction of plant biomass in Arctic landscapes during peak years (12–24%) as previously shown … Continue reading UAV reveals substantial but heterogeneous effects

A doubling of stony coral cover on shallow forereefs

To better understand the decline of one of earth’s most biodiverse habitats, coral reefs, many survey programs employ regular photographs of the benthos. An emerging challenge is the time required to annotate the large volume of digital imagery generated by these surveys. Here, we leverage existing machine-learning tools (CoralNet) and develop new fit-to-purpose programs to process and score benthic photoquadrats using five years of data … Continue reading A doubling of stony coral cover on shallow forereefs

Weak impact of microorganisms on Ca, Mg-bearing silicate weathering

Assessment of the microbial impact on mineral dissolution is crucial for a predictive understanding of basic (Ca, Mg bearing) silicate weathering and the associated CO2 consumption, bioerosion, and CO2 storage in basaltic rocks. However, there are controversies about the mechanism of microbial effect, which ranges from inhibiting via nil to accelerating. Here we studied diopside interaction with the heterotrophic bacterium Pseudomonas reactants and the soil fungus Chaetomium brasiliense using a combination … Continue reading Weak impact of microorganisms on Ca, Mg-bearing silicate weathering

Tuber yield and water efficiency of early potato varieties

This study aims to determine the effects of differences in variety and irrigations levels on potato yield (appropriate humidity, temperature, shading the plants from the sun if necessary) on potato yield in greenhouse conditions. Functions of potato production with respect to water use were developed for five dates of measurements of plant growth, in relation to the various vegetation phases. On the basis of potato … Continue reading Tuber yield and water efficiency of early potato varieties

Nanosilica modified with polyaspartic acid as an industrial circulating

Given the special performance of nanosilica with its small size, large specific surface area and high surface activity, nanosilica containing reactive amino group (denoted as SiO2–NH2) and polysuccinimide were allowed to take part in polymerization reaction to afford SiO2–NH2modified polyaspartic acid (denoted as SiO2–NH2/PASP), a potential polymer scale inhibitor with good water solubility for industrial circulating water. The scale inhibition performance of the as-prepared SiO2–NH2/PASP … Continue reading Nanosilica modified with polyaspartic acid as an industrial circulating

Influence of storms on the emission of pollutants from sewage into waters

Fig: Arrangement of rain gauges and storm overflows on the sewage network in the area of the considered catchment. OS-1 ÷ 3—overflow structures; 1–6—rain gauges; STP—sewage treatment plant. During heavy precipitation, chemical and biological pollutants from urban and agricultural areas enter the waters from storm overflows as a result of infiltration and inflow, as well as via uncontrolled outflows from water treatment plants. Infiltration and inflow of … Continue reading Influence of storms on the emission of pollutants from sewage into waters

Decreased Coloured Dissolved Organic Matter Build-up and Nutrients

A team of researchers at CSIR-National Institute of Oceanography (CSIR-NIO), Goa, studied the variations of Coloured Dissolved Organic Matter (CDOM) in the Mandovi Estuary, Goa — “During Spring Inter-Monsoon: A Comparison with COVID-19 Outbreak Imposed Lockdown Period”. One of the chemical parameters of importance is the Dissolved Organic Matter (DOM) in the water, which is the largest reservoir of organic carbon in the aquatic environment. … Continue reading Decreased Coloured Dissolved Organic Matter Build-up and Nutrients
