The thermal–chemical conversion method has significant potential for the recovery of organic matter present in sewage sludge (abbreviated as SS), offering broad market prospects. In this study, a novel approach is proposed preparation composite adsorbent, named SS-EP, derived from co-pyrolysis residue and Enteromorpha prolifera. An orthogonal experiment was designed to investigate performance r...

PURPOSE To study the safety, technical efficacy, and histopathology of the ethylene vinyl alcohol copolymer (EVAL) embolic mixture in an animal model. METHODS Microcatheterization of the rete was performed in 29 swine. The clinical, angiographic, and histopathologic consequences of superselective injection of the two principal embolic mixture components (EVAL and dimethyl sulfoxide [DMSO]) we...

Processes controlling preservation and accumulation of organic matter (OM) in marine sediments are highly sensitive towards both natural anthropogenic impacts. Thus, the sedimentary OM is considered a key proxy for characterization recent past environments . Along Peruvian continental margin (PCM), high primary production an intense oxygen minimum zone (OMZ) favor sediments. Spatial variations ...

This paper dealt with the controlled release of two kinds of drugs, 5-fluorouracil (5-FU) and hydrocortisonum (Hydro.) and loaded poly(ethylene-vinylalcohol) (EVAL), which composed 5-FU/EVAL and Hydro./EVAL matrix systems. The results were analyzed using the pseudo-steady-diffusion models coupled with the fundamental concepts of percolation theory. The percolation thresholds for the two systems...

Rock salt represents a potential host rock formation for the final disposal of radioactive waste. The interactions between indigenous microorganisms and radionuclides, e.g. uranium, need to be investigated to better predict the influence of microorganisms on the safety assessment of the repository. Hence, the association process of uranium with two microorganisms isolated from rock salt was com...
