wastewater. Colored effluents are associated with the production and use of dyes, the
presence of dyes in aquatic systems has become ...
Energy is one of the limiting parameters for the economic growth of one nation. Energy could be
generated from various sources and biogas can be one among to be mentioned. Biogas production
is a key technology in the ...
Natural fish bones, that are known to have unique adsorption capacity, have been used in
the present work for removal of heavy metals, copper, and lead, from wastewater. The
effects of solution pH, adsorbent dose, ...
The main objective is to investigate the utilization of waste polyethylene bags for the
manufacturing of non-load bearing Hollow Concrete Blocks (HCB) partially replacing
the sand volume and analyzing ...
Due to urbanization, the storage of short wave radiation in the impervious surfaces and
the reduction of cooling service of vegetated areas awing to its depletion leads to an
elevated heat in urban area. Similarly ...

The gut microbiota of fish plays a key role in many biological processes of their host.
However, there is lack of understanding of gut microbial dynamics of the Nile tilapia
(Oreochromis niloticus L. 1758) under ...
Even though maize is a staple crop in Ethiopia, an ineffective postharvest management
system results in a considerable postharvest loss. This loss occurs along the value chain
from harvest to storage. This study ...
