We prove a certain Riemann-Roch type formula for symmetric powers of Galois modules on Dedekind schemes which, in the number field or function field case, specializes to a formula of Burns and Chinburg for Cassou-Noguès-Taylor operations. Introduction Let G be a finite group and E a number field. Let OE denote the ring of integers in E, Y := Spec(OE), and Cl(OYG) := ker(rank : K0(OEG) → Z) the ...

Let X be a completely regular Hausdorff space, E a Hausdorff topological vector space, CL(E) the algebra of continuous operators on E, V a Nachbin family on X and F ⊆ CVb(X,E) a topological vector space (for a given topology). If π : X → CL(E) is a mapping and f ∈ F , let Mπ(f)(x) := π(x)f(x). In this paper we give necessary and sufficient conditions for the induced linear mapping Mπ to be a mu...

Dynamical properties of F –water and Cl –water hydrogen bonds in aqueous solution have been studied by ab initio QM/MM molecular dynamics simulations, in which the whole first hydration sphere of the anion was treated at Hartree–Fock level using respe ies as lvat D95V+, 6-31+G and D95V++ basis sets for F , Cl and water, and shifts in the corresponding bending and stretching frequenc ing the ion...

Xylometazoline is a drug which is used as a topical nasal decongestant. It is applied directly into the nose, either as a spray or as drops. Xylometazoline is an imidazole derivative which is designed to mimic the molecular shape of adrenaline. It binds to alpha-adrenergic receptors in the nasal mucosa. Due to its sympathomimetic effects, it should not be used by people with high blood pressure...

As one of the youngest back-arc basins, evolutionary behavior magmatic volatiles in Eastern Manus Basin has been poorly studied. Recently, apatite received widespread attention for its powerful function recording information on volatiles. In this paper, by determining major element compositions and primary volatile abundances (F, Cl, SO3) apatites dacite, we analyze before magma eruption Basin,...

In the title compound, C(23)H(17)Cl(2)F(3)N(2)O(3), the mol-ecular conformation is significantly strained: atoms O, C(=O) and C attached to the central benzene ring deviate from its plane by 0.118 (2), 0.139 (2) and 0.174 (2) Å, respectively. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into chains along [110]. The crystal packing exhibits short inter-molecular Cl⋯F [2.9840 (16)...

a novel podand based anion receptor bearing benzimidazole motifs as recognition sites was designed and synthesized by reaction of 1,7-bis(2'-methylbenzoate)-1,4,7-trioxaheptane and phenylenediamine. the binding properties of anionic guest with this receptor were studied using uv-vis and fluorescence spectroscopy. these studies revealed that this receptor exhibit selective recognition towards f- ...

BACKGROUND Cutaneous leishmaniasis (CL) is a major health problem in many parts of Iran, although diagnosis of CL especially in the endemic area is easy, but treatment and management of the disease is a global dilemma. Diagnosis of CL in non-endemic area is not as simple as in endemic foci. In this study, the status and the proportions of CL induced by Leishmania major and L. tropica among CL s...

In this paper, the effect of halogen compounds on tetrahedrozoline with nanosized fullerene was investigated. First, the structures of Tetrahydrozoline on a fully vectorized nanoclay were optimized with halogen compounds on carbon 69 (R-X: X = F, Cl, Br; R = C60-Tetrahydrozoline-C69-). Then orbital calculations were performed using NBO technique, and structural parameters and bipolar moments of...
