Clean drinking water. It is something that the public has pretty much taken for granted for the past hundred years. The public has little idea and, perhaps understandably, little interest, in the many people and agencies struggling daily to ensure that drinking water remains uncontaminated. But our environment is changing, new pathogens are emerging, drinking water systems are aging, and govern...

The flow rate of water through carbon nanotube (CNT) membranes is considerably large. Hence, CNT membranes can be used in nanofluidic applications. In this work, we performed a molecular dynamics (MD) simulation of the introduction of water into CNTs in the CNT membranes, especially in vertically aligned CNT forests. The results showed that the Knudsen number (Kn) increased with an increasing v...

Serum levels of alpha1-antitrypsin (alAT) were measured by radial immunodiffusion and phenotypes were determined by electrofocusing in acrylamide gel in 39 patients with hepatocellular carcinoma (HCC) positive for serum hepatitis B surface antigen (HBsAg), 41 patients with HCC negative for serum HBsAg, and 160 ageand sex-matched hospital controls. There was no difference between the control ser...

in this study, a three–layer artificial neural network (ann) model was developed to predict the pressure gradient in horizontal liquid–liquid separated flow. a total of 455 data points were collected from 13 data sources to develop the ann model. superficial velocities, viscosity ratio and density ratio of oil to water, and roughness and inner diameter of pipe were used as input parameters of t...

Brexit may have dominated the 2019 general election campaign, but it wasn't only issue at stake. The political parties published wide-ranging manifestos, while their appeals also rested on established ideological reputations. This article analyses content of manifestos and uses latest Manifesto Project estimates to explore movement in British party system. It reports changing policy emphases Co...
