Research in abstract argumentation typically pertains to finite argumentation frameworks (AFs). Actual or potential infinite AFs frequently occur if they are used for the purpose of nonmonotonic entailment, so-called instantiation-based argumentation, or if they are involved as modeling tool for dialogues, n-person-games or action sequences. Apart from these practical cases a profound analysis ...

Purpose The purpose of this study was to characterize the relation between corneal hydration and stiffening effects of the UVA/riboflavin collagen crosslinking treatment and to investigate how artificially swelling the cornea prior to this treatment procedure affects tensile property improvement. Methods Porcine corneas were collagen crosslinked in vitro at different hydration levels using a ...

We have investigated Ca(2+)-involving cell signaling, plasma membrane potentials and conductances and callose formation during early stages of pollination of papillae of Brassica napus. Using fluorescence imaging of calcium green-1, we found that application of a range of pollen types and controls all rapidly produced small localized peaks in papillar cytoplasmic [Ca2+]. This response was more ...

calcium aluminates (ca) are the most important hydraulically setting cements used for preparing refractory castables, because they develop high strength at very early ages after placements.  the anhydrous phases of this kind of cements are ca, ca2 and traces of c12a7 and alpha-alumina. the major hydraulic phase in all of the ca cements including ciment fondue is ca. once hydrated, it starts to ...

the current methods for treatment of cancers are inadequate and more specific methods such as gene therapy are in progress. among different vehicles, cationic liposomes are frequently used for delivery of genetic material. this investigation aims to prepare and optimize dotap cationic liposomes containing an antisense oligonuclotide (asodn) against protein kinase c alpha in non-small cells lung...

The hydration of mantle rocks occurs at mid-ocean ridges, in subduction zones and ophiolites where it strongly modifies the properties oceanic lithosphere. nanostructure reaction products is poorly constrained, but very important, as controls fluid transport during solid volume increase, influences phase reactivity further fluid/rock interaction low temperature. We image contacts between olivin...

The hydration of polar and apolar groups can be explained quantitatively, via the random network model of water, in terms of differential distortions in first hydration shell water-water hydrogen bonding angle. This method of analyzing solute induced structural distortions of water is applied to study the ice-binding type III thermal hysteresis protein. The analysis reveals subtle but significa...

background: despite almost the three decades passed since the chemical attacks of iraqi’s army against the iranian troops, some veterans are still suffering from long-term complications of sulfur mustard (sm) poisoning, including certain skin complaints specially dryness, burning, and pruritus. we thus aimed to evaluate the skin’s water and lipid content in patients with a disability of >25% du...

this study assesses the kinetics of hydration of pulverised fuel ash and metakaolin cement pastes and compares how the rate of reaction affects the pore-characteristics and resistance to ionic ingress. the degrees of hydration for the different mixtures were evaluated, both as a function of the calcium hydroxide content and with respect to the chemically combined water contents. the reaction ra...

CONTEXT Currently, the literature on hot yoga is lacking, and there is still much to understand regarding the safety of these practices. However, one point of safety often emphasized is hydration during the practice of hot yoga. AIM The aim of this study was to examine hydration encouragement by hot yoga instructors and hydration behaviors and related outcomes by hot yoga participants. METH...
