(0.47 °C/decade and 0.38 °C/decade, respectively) have increased significantly in the NW; consequently, this region has been warmed by 0.27 °C/decade. The increase in temperature and decrease in WS may cause a decrease in rainfall in the NW region. Humidity changes are not significant except in the ...

Clay minerals are significant indicators that can be used to identify sources and transport patterns of both fluvial and marine sediments. The Ganges, Brahmaputra, and Surma-Meghna (SM) rivers are the most important rivers of the Bengal Basin (BB), loading a large amount of sediments from the Himala...

Abstract Lead (Pb) is a widely occurring heavy metal employed in industrial products and hence released into the environment, causing several environmental health risk concerns. This study comprehensively surveyed the literature on Pb contamination in different agricultural foods and food products c...

Heavy metals (Sc, Cr, Co, Ni, Cu, Ga, Ge, Nb, Mo, Cd, In, Hf, Ta, W, Tl, Pb, Bi, Th, and U) in the surface sediments of the Ganges-Brahmaputra-Meghna (GBM) river system of the Bengal Basin (BB) were measured to evaluate the heavy metal contamination and anthropogenic influence. The average concentra...

The interaction between water vapor and natural/anthropogenic airborne particles deposits a massive amount of trace elements in the ecosystem. As the principal source region of the Indian monsoon originated from the Bay of Bengal, atmospheric trace elements in Bangladesh have impacted atmospheric we...

There is a recognized need for the evaluation of the physico-chemical properties of municipal wastewater before discharging into rivers, canals, ponds, agricultural fields and/or further uses. Since physico-chemical parameters beyond its standard or safe limit may cause a substantial damage to the r...

This study aimed to understand the sources and transport mechanism of organic matter (OM) in the Ganges-Brahmaputra-Meghna (GBM) river system in Bangladesh. We conducted analyses of total organic carbon (TOC), total nitrogen (TN), their stable isotopes (δ13C and δ15N), and sediment grain size. The r...

Metal pollution in sediment from construction areas raises ecological and health concerns, yet source-based sediment pollution in Bangladesh remains understudied. Our investigation focused on fifteen locations in the Kohelia River and the coastal regions near the Matarbari projects (Matarbari Power ...

Abstract The overall performance of gas reservoirs and the optimization of production, as well as its sensitivity analysis, are affected by several factors such as reservoir pressure, well configuration and surface facilities. The Habiganj well no. 06 (HBJ-06) is one of the significant gas-producing...

Threshed grain contains impurities which should be removed as soon as possible after harvesting and certainly before storage. A clean grain has esteem value, improves storability, reduces price penalties, and improves milling quality. Traditionally farmers use wind or fan to remove foreign matter fr...

This study aimed to develop lightweight building blocks using Expanded Polystyrene (EPS) with varying percentages, assess their properties, including density, water absorption, porosity, and compressive strength, and evaluate the unit cost of the blocks. The heat-passing rate of the blocks was also ...

The existing BRRI Hydro-tiller was tested at BRRI West byde to find out the causes of frequent tearing of the hydro-tiller chain. Its capacity was found 0.023 ha/hr. The reason associated with the fault of hydro-tiller chain tearing was identified i.e. thickness of the chain was not sufficient to be...
