Water pollution is one of the greatest challenges around the world. Nanocomposite
membranes are a promising modified version of traditional polymeric membranes for water …

(1) Different methods have been applied to fabricate polymeric membranes with non-solvent
induced phase separation (NIPS) being one of the mostly widely used. In NIPS, a solvent or …

Sirtuins are evolutionarily conserved proteins that use nicotinamide adenine dinucleotide
(NAD+) as a co-substrate in their enzymatic reactions. There are seven proteins (SIRT1-7) in …

Objective: Spontaneous pneumomediastinum is characterized by the presence of interstitial
air in the mediastinum without any apparent precipitating factor. The purpose of this study is …

The objective of this study was to evaluate the necessity of measuring both assimilable
organic carbon (AOC) and biodegradable dissolved organic carbon (BDOC) as indicators of …

W'hereas, at sea level, S for fixed N can be ex-pressed as an exponential function of sec&
(which is proportional to the slant thickness of the atmosphere), at 4200 m we findthat S (for …

Two distribution systems, one treating water by ozonation and another treating water by
nanofiltration in parallel with lime softening, were monitored for bacterial growth. Both …

Organic solvents, such as N-methyl-2-pyrrolidone (NMP) and dimethylacetamide (DMAc),
have been traditionally used to fabricate polymeric membranes. These solvents may have a …

Intracellular ion channels are essential regulators of organellar and cellular function, yet the
molecular identity and physiological role of many of these channels remains elusive. In …

In this work, we propose an inexpensive laboratory practice for an introductory physics
course laboratory for any grade of science and engineering study. This practice was very …
