Biogeochemistry of metals in aquatic sediments is strongly influenced by bioturbation. To determine the effects of biological transport on cadmium distribution in freshwater sediments, a bioturbation model is explored that describes the conveyor-belt feeding of tubificid oligochaetes. A stepwise modelling strategy was adopted to constrain the many parameters of the model: (i) the tubificid tran...

In this study, the effect of pretreatment and solid-state fermentation (SSF) on tempeh protein content has been studied. Pretreatment SSF are important processes for producing high-quality tempeh. Based results analysis using a UV-Vis spectrophotometer at ?max = 540 nm, it is known that both cause reduced content. causes total (w/w) to decrease rapidly from 1.05% 0.82%, while dissolved 0.57% 0....

Abstract Background A lot of factors contribute to the breeding Anopheles mosquitoes, especially vectors malaria parasites. This indirectly contributes transmission these The physicochemical parameters associated with population larvae were studied for period twelve months in five selected communities Akure North Local Government area Ondo State. study was carried out understand relationship be...

Alexandria Governorate contracted an international company in the field of municipal solid waste management for the collection, transport and disposal of municipal solid waste. Construction and operation of the sanitary landfill sites were also included in the contract for the safe final disposal of solid waste. To evaluate the environmental impacts associated with solid waste landfilling, leac...

this study illustrates the process of removal of chromium from chrome tanning waste-water by fly ash which was drive from chrome shaving dust. this experiment was carried out in a batch process with laboratory prepared adsorbent samples and chrome tanning water collected from local tanneries. the influence of various factors likes adsorbent doses, contact time, and initial concentration of chro...

Solid lipid nanoparticles (SLN) have been reported to be an alternative system to emulsions, liposomes, microparticles and their polymeric counterparts for various application routes since the early 1990s due to their advantages. Solid lipid nanoparticles colloidal drug carrier system gained a lot of popularity among researcher as colloidal drug carriers for incorporating hydrophilic or lipophi...
