Stress Management: COVID-19 - Psychological and Spiritual Context.

Any crisis (personal or collective) brings along an in-built stress. It cripples people from living a normal life; sometimes it leads people to the extreme condition of permanent damage. The COVID-19 situation has brought in unexpected misery - victimizing millions of people.

Two-scale multi-model ensemble: is a hybrid ensemble of opportunity telling us more?

In this study we introduce a consisting of air quality models operating at both the global and regional scale. The work is motivated by the fact that these different types of models treat specific portions of the atmospheric spectrum with different levels of detail, and it is hypothesized that their combination can generate an ensemble that performs better than mono-scale ensembles. A detailed analysis of the hybrid ensemble is carried out in the attempt to investigate this hypothesis and determine the real benefit it produces compared to ensembles constructed from only global-scale or only regional-scale models.

Wear Behavior of Aluminium Metal Matrix Composite Prepared from Industrial Waste.

With an increase in the population and industrialization, a lot of valuable natural resources are depleted to prepare and manufacture products. However industrialization on the other hand has waste disposal issues, causing dust and environmental pollution. In this work, Aluminium Metal Matrix Composite is prepared by reinforcing 10 wt% and 20 wt% of wet grinder stone dust particles an industrial waste obtained during processing of quarry rocks which are available in nature.

Evaluation of extracts of the root of Seidenfia rheedii (Sw.) Szlach. for antibacterial activity.

In the present investigation, aqueous, ethanol and petroleum ether, ethanol (1:1) root extracts of Seidenfia rheedii were tested against 12 different human pathogenic bacteria for antibacterial activity. It was found that ethanolic extracts inhibited the growth of all the bacterial strains tested whereas moderate antibacterial activity was associated with petroleum ether, ethanol (1:1) root extracts. The aqueous extract did not show antibacterial activity.

ANTIMICROBIAL SCREENING OF LEAVES OF Memecylon umbellatum.

The present study includes antimicrobial activity of Memecylon umbellatum Alcoholic extract showed maximum antibacterial activity Staphylococcus aureus. (gram positive) and it also showed antibacterial activity against gram negative bacteria and also alcoholic extract alone showed slight antifungal activity.

ANTIBACTERIAL ACTIVITY OF STEM EXTRACTS OF TINOSPORA CORDIFOLIA (Willd) Hook. f & Thomson.

The antibacterial activity of the aqueous, ethanol and chloroform extracts from the stems of Tinospora cordifolia  was studied using disc diffusion method against Escherichia coil, Proteus vulgaris, Enterobacter faecalis, Salmonella typhi (Gram-negative), Staphylococcus aureus and Serratia marcesenses (Gram-positive). Results suggest that the ethanolic extract has significant antibacterial activity against tested bacteria. The present study justifies the claimed uses of Tinospora cordifolia  in the traditional system of medicine to treat various infectious diseases.
