hat EWS is being used as a decision aid but is not a true severity of illness score. Other, non-EWS data are needed for earlier detection and for prioritizing access to critical care.Assessment of land use/land cover change (LULCC) and its effects on the natural environment are important in policy decision making for sustainable environment. This study investigated and assessed the environmental impacts of artisanal and small-scale mining operations on environmental degradation resulting from such activities in selected host communities (Akoko Edo, Ijero and Ilesa). Vegetation, water, built-up expansion and land surface temperature dynamics were examined and analysed using appropriate indices for the years 1987, 2002 and 2017. A gradual decrease in the normalised difference vegetation index (NDVI) values was observed across Akoko Edo and Ijero Ekiti with a corresponding change in the highest NDVI values while Ilesa witnessed a higher NDVI value in 2017 relative to the previous years. The majority of the normalised difference water index (NDWI) values for 2017 appear to be above 0 in all the host communities. Mean land surface temperature (LST) values are in the order 24.63 °C (1986) less then 25.26 °C (2002) less then 26.32 °C (2017) for Ijero Ekiti study area while mean LST values are in the order 24.30 °C (1986) less then 24.46 °C (2002) less then 25.82 °C (2017) in Ilesa study area. Modified Normalized Difference Water Index (MNDWI) seemed a more reliable indicator as the index was able to enhance the water surfaces more clearly as indicated in the case of Akoko Edo study area. Due to its high heat capacity, high land surface temperatures were experienced over urban areas and uncultivated bare land during all the periods of study. The study showed that changes in land covers have affected the normal functioning of the habitats through urbanisation. Adequate natural resource management is therefore necessary to ensure sustainable development through effective policy formulation.As a common heavy metal, chromium and its compounds are widely used in industrial applications, e.g., leather tanning, electroplating, and in stainless steel, paints and fertilizers. Due to the strong toxicity of Cr(VI), chromium is regarded as a major source of pollution with a serious impact on the environment and biological systems. The disposal of Cr(VI) by biological treatment methods is more favorable than traditional treatment methods because the biological processes are environmentally friendly and cost-efficient. This review describes how bacteria tolerate and reduce Cr(VI) and the effects of some physical and chemical factors on the reduction of Cr(IV). The practical applications for Cr(VI) reduction of bacterial cells are also included in this review.The present study assessed the impact of fingerling stocking of Indian major carps (Gibelion catla, Labeo rohita, and Cirrhinus mrigala) on fish yield in 24 small reservoirs of Central India. The time series data on fish stocking and yield were collected from the State Fisheries Department, Govt. of Chhattisgarh, for the year 2008 to 2016. The fish yield increased significantly (p less then 0.05) from 87.11 to 379.13 kg/ha/year due to stocking indicating significant impact on fish production. The relationships between area, stocking density, and fish yield of reservoirs were also assessed. Stocking had a significant positive impact on fish yield (t test, p less then 0.05). The important water quality parameters were also studied to have a conspicuous picture of eco-hydrological characteristics of these selected small reservoirs. The study forms a baseline for the small tropical reservoir fisheries of Central India (Chhattisgarh state) and suggests regional strategies for sustainable fisheries enhancement and management, employment generation, and nutritional security of a large number of fish-eating population.The increasing use of nanoparticles and their many applications increases the likelihood of their presence in the environment. This possibility of presence necessitates the study of the effect of these substances on aquatic species. In this research, CoWO4 nanoparticles were synthesized by the ultrasonic method. Various conditions in the synthesis process were investigated to obtain the appropriate size of the nanoparticles. After selecting the optimum particles, these nanoparticles were used to investigate their effect on the growth of Dunaliella salina. GS-9674 For this purpose, the algal cells were subjected to three different concentrations of nanoparticles (15, 30, and 60 mg/L). The study results on algae growth parameters showed that these parameters depend on the value of nanoparticles. At 15 and 30 mg/L concentrations of the nanoparticles, numbers of cells, specific growth, biomass, and pigments showed a significant boost compared to the mentioned parameters of the control treatment. Measurement of malondialdehyde (MDA) showed that this parameter was directly related to the increase in the concentration of nanoparticles. At 60 mg/L of the nanoparticles, the MDA level was higher than the control and other treatments. This increase reflects the destructive effect of the nanoparticles on algal cells. Finally, the results showed that algae could be useful for studying the environmental effects of nanoparticles and their safety.In view of the significance of transportation management and logistics in the economic concept and raising the productivity of production systems, well-timed procurement of perishable materials and goods is determined as a pivotal prerequisite for economic and environmental development. Since the perishable goods produced must be made delivered to consumers as early as possible on account of the limited lifespan, thus, the vulnerability of these products is extremely high, owing to the high cost of transportation as well as the environmental impacts. So that solves this problem, this study represents a problem of dynamic green vehicle routing of perishable products in green traffic conditions that optimizes the total cost for a dynamic transportation network and minimizes environmental influences, and increases customer satisfaction. The introduced model is implemented in light of time windows as a trustworthy solution for monitoring the dynamic logistics process and attaining instantaneous information on the basis of the green traffic situation and travel duration, which is commonly known by the Logit function.
