(Elsevier, 2008-10-23)Experimental observations show that for the gas phase isomerization of protonated molecules, a third body can transport a proton from a high-energy site to a lower energy-site of the substrate, thereby catalyzing the ...

(SPRINGER HEIDELBERG, 2008-03)The bronchial tree of most mammalian lungs is a good example of an efficient distribution system whose geometry and dimensions of branched structures are important factors in determining the efficiency of respiration. Small ...
-
(ELSEVIER, 2010)The existence and uniqueness of pseudo-almost periodic solutions to general neutral integral equations with deviations are obtained. For this, pseudo-almost periodic functions in two variables are considered. The results ...

(John Wiley and Sons Ltd, 2017)© 2017 John Wiley & Sons, Ltd. Using the existence of integrable bi-almost-periodic Green functions of linear homogeneous differential equations and the contraction fixed point, we are able to prove the existence of almost ...
-
(1987)The ground state potential energy curves of alkaline-earth monohydride ions have been investigated. A pseudopotential formalism including a corepolarization potential has been used. For the valence correlation energy a ...

(2016)This paper introduces a mathematical model of control for an animal epidemic outbreak in an ideal farm. What has been considered for this is poultry, aquaculture or livestock affected by an infectious disease (without ...
-
(BioMed Central, 2017)Background: Amylases are used in various industrial processes and a key requirement for the efficiency of these processes is the use of enzymes with high catalytic activity at ambient temperature. Unfortunately, most ...

(1992)Two isoenzymes of ATP-diphosphohydrolase (apyrase) were extracted and purified from S. tuberosum var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were 1.0 (apyrase B) and ca 15.0 (apyrase A). They were ...

Putative ClC-2 chloride channel mediates inward rectification in Drosophila retinal photoreceptors (SPRINGER, 2005-10)We report that Drosohhila retinal photoreceptors express inwardly rectifying chloride channels that seem to be orthologous to mammalian CIC-2 inward rectifier channels. We measured inwardly rectifying Cl- currents in ...
