As plasma membranes of animal cells are known to be asymmetric, the transmembrane lipid asymmetry, being essential for many membranes' properties and functions, should be properly accounted for in model membrane systems. In this paper, we employ atomic-scale molecular dynamics simulations to explore electroporation phenomena in asymmetric model membranes comprised of phosphatidylcholine (PC) an...

In apparent, the intension is removal of chromium using cow dung as low cost adsorbents from the industrial wastewater. Chromium (Cr) is one of the most toxic substances and is introduced into the environment through a variety of industrial activities. In order to remove the chromium from the contaminated water there are lot of methods available, even though they are not in natural way. In the ...

The Grímsvötn volcanic eruption, from 21 to 28 May, 2011, was the largest eruption of the Grímsvötn Volcanic System since 1873, with a Volcanic Explosivity Index (VEI) of magnitude 4. The main geochemical features of the potential environmental impact of the volcanic ash-water interaction were determined using two different leaching methods as proxies (batch and vertical flow-through column exp...

Water solubility is an important characteristic of a chemical in many aspects. However experimental definition of the endpoint for all substances is impossible. In this study quantitative structure-property relationships (QSPRs) for negative logarithm of water solubility-logS (mol L(-1)) are built up for five random splits into the sub-training set (≈55%), the calibration set (≈25%), and the te...

When the conditions of a competitive market are simulated in a game, the number of people deciding to enter each round approaches the game-theoretic equilibrium after a few rounds. This occurs even when there is no communication between players, and the only feedback on each round relates to the number of entrants. However, in real markets entry is generally too high, resulting in too many star...

Although mouse development is regulative, the cleavage pattern of the embryo is not random. The first cleavage tends to relate to the site of the previous meiosis. Sperm entry might provide a second cue, but evidence for and against this is indirect and has been debated. To resolve whether sperm entry position relates to the first cleavage, we have followed development from fertilization by tim...

The title compound (systematic name: 2,6-dimethyl-1H-pyridin-4-one hemihydrate), C7H9NO·0.5H2O, has a single planar mol-ecule in the asymmetric unit with the non-H atoms possessing a mean deviation from planarity of 0.021 Å. There is also half of a water mol-ecule present in the asymmetric unit. In the crystal, infinite (001) sheets are formed by N-H⋯O and O-H⋯O hydrogen bonds.

Assuming asymmetric information over farmer profits and zero transaction costs, prior literature has suggested that when regulating nonpoint source water pollution, a tax on management practices (inputs) can implement full-information allocations and is superior to a tax on estimated runoff. Using mechanism design theory under asymmetric information, this paper shows that under the same assumpt...

This is the first report on the asymmetric transfer hydrogenation (ATH) of dibenzo[b,f][1,4]oxazepine compounds in the presence of an (R,R)-Ru-Ts-DPEN complex. The developed catalytic asymmetric protocol provides biologically active 11-substituted-10,11-dihydrodibenzo[b,f][1,4]oxazepines with excellent conversion (up to >99%) and high enantioselectivity (up to 93% ee) in water as an environment...

The City of Merida, in the State of Yucatán, obtains its drinking water primarily from three well fields located in the periphery of the city. In addition, there are water supply wells within the city. Water from the public water supply contains lead, cadmium, chromium in excess of the Mexican Drinking Water Norm. The following organic contaminants have also been identified in the ground water ...
