This study investigated the effects of soluble organic matters on membrane fouling characteristics, using silt density index (SDI) and modified fouling index (MFI) to evaluate the fouling potential. Experimental results demonstrated that humic acid had significant effects on membrane fouling indexes. When its concentration was in the range of 0.01-0.05 mg/L, the SDI(15) and MFI were 2.9-3.9 and...

Late Holocene paleoclimate records from coastal regions are important for understanding long-term variability of hurricane activity. Here we present a nearly 4000-year record of severe storm landfalls and environmental changes based on organic geochemical proxies (OGPs) preserved in sediment cores from two coastal lakes in northwest Florida. Our analysis shows that there are significant variati...

Niche membrane technologies, such as organic solvent nanofiltration (OSN), offer considerable energy and operation cost reduction compared with conventional separation methods. However, despite their many advantages, industrial implementation is hindered by small specialized datasets, which hinders the development of more advanced prediction In this study, we developed a medium-throughput syste...

soil compaction is one of the most prevailed limitations for crop growth. the use of organic matters as fertilizer on agricultural soils can reduce the effects of soil compaction and provide the nutrients for the plants. so, a factorial experiment was carried out in a randomized complete blocks design with three replications. the first factor was the source and amount of organic fertilizer (far...

Context. Hot corinos are compact regions around solar-mass protostellar objects that very rich in interstellar Complex Organic Molecules (iCOMs). How the abundance of these molecules is affected by environmental physical conditions still an open question. More specifically, addressing this point key to understand our own chemical origins since Solar System formed a large cluster low- high-mass ...

Renewable energy from lipid removed microalgal residues (LRμARs) serves as a promising tool for sustainable development of the microalgal biodiesel industry. Hence, in this study, LRμAR from Ettlia sp. was characterized for its physico-biochemical parameters, and applied to various pretreatment to increase the biodegradability and used in batch experiments for the production of volatile fatty a...

How does a redistribution of trade gains affect welfare when income inequality matters? To answer this question, we extend the [1] model to unionized labor markets and heterogeneous workers. As redistribution schemes, we consider unemployment benefits that are financed either by a wage tax, a payroll tax or a profit tax. Assuming that welfare declines in income inequality, we find that welfare ...
