Pulsed laser driven modifications of one Cl monolayer (ML) chemisorbed on Si(100) are studied by time of flight mass spectrometry (TOF) of the desorbed molecules, Auger electron spectroscopy @ES) of the modified surface, and Cl depth profile analysis by secondary ion mass spectrometry (SIMS). The experimental conditions are that of surface melting. Evidence of Cl diffusion to the bulk during su...

UDP-glucuronosyltransferase (UGT) is highly expressed in the small intestine and catalyzes the glucuronidation of small molecules, which may affect the oral bioavailability of drugs. However, no method of predicting the in vivo observed fraction of absorbed drug (F(a)F(g)) affected by UGT has yet been established. Here, we investigated the relationship between F(a)F(g) and in vitro clearance of...

Let K be an imaginary quadratic field and f an integral ideal. Denote by Cl(f) the ray class group of f. For every non-trivial character χ of Cl(f), we show that L(1, χ)/π is transcendental. If f = f, then complex conjugation acts on the character group of Cl(f). Denoting by Ĉl(f) + the orbits of the group of characters, we show that the values L(1, χ) as χ ranges over elements of Ĉl(f) + are l...

the character of the intermolecular interactions in cl2-hx (x =f, cl and br) complexes has been investigated by means of the second-order möller–plesset perturbation theory (mp2) and the density functional theory (dft) calculations. the results show that there are two types of lowest interaction potential equilibrium structures in the interactions between cl2 and hx: x∙∙∙cl type geometry and hy...

Ultra-high-pressure (UHP) eclogites and ultramafites associated fluid inclusions from the Western Gneiss Region, Norwegian Caledonides, have been analysed for F, Cl, Br I using electron-probe micro-analysis, time-of-flight secondary ion mass spectrometry neutron-irradiated noble gas spectrometry. Textures of multi-phase in cores silicate grains indicate formation during growth host crystal at U...

   In This research the effect of fluorine and chlorine substituents on the electronic and opticalproperties of pentacene molecule have been investigated based on density functional theory as implemented in SIESTA code. The results show thatthe full replacement of hydrogen atoms with fluorine and chlorine in pentacene molecule, leads to ...

A fullerene is any molecule composed entirely of carbon, in the form of a hollow sphere.Naphazoline is a sympathomimetic agent with marked alpha adrenergic activity. It is a vasoconstrictor with a rapid action in reducing swelling when applied to mucous membrane. It acts on alpha-receptors in the arterioles of the conjunctiva to produce constriction, resulting in decreased congestion. It is an ...

Abstract. In this paper, the authors defined a multifunction F : X → Y to be upper (resp. lower) weakly α-continuous if for each x ∈ X and each open set V of Y such that F (x) ⊂ V (resp. F (x) ∩ V 6= ∅), there exists an α-open set U of X containing x such that U ⊂ F(Cl(V )) (resp. U ⊂ F−(Cl(V ))). They give some characterizations and several properties concerning upper (lower) weakly α-continuo...

A series of new tetrasubstituted imidazoles 2-phenyl-3-(1, 4, 5-triphenyl-1H-imidazol-2-yl)-1H-indole derivatives substituted with –F, Cl, Br, I,-OCH3 and -NHCOCH3 were synthesized using a multicomponent reaction. The compounds were obtained in good yields by easy workup and with high purity
