Molecular dynamics calculations of collision-induced absorption in a gas mixture of neon and krypton.

We continue the development of the in-house molecular dynamics software package SpaCIAL and test it for the computation of the collision-induced absorption coefficients for a neon (Ne) and krypton (Kr) gas mixture. An apodization procedure for the dipole autocorrelation function is implemented and tested. We also carry out a statistical study of the convergence rate with respect to ensemble size.

Collision-induced absorption in Ar-Kr gas mixtures: A molecular dynamics study with new potential and dipole data.

We have implemented a scheme for classical molecular dynamics simulations of collision-induced absorption. The program has been applied to a gas mixture of argon (Ar) and krypton (Kr). The simulations are compared with accurate quantum dynamical calculations.

Contraceptive use by Palestine refugee mothers of young children attending UNRWA clinics: a cross-sectional follow-up study.

Background: UNRWA introduced family planning services in 1994 as an integral part of its expanded maternal and child health-care programme. The main objective of UNRWA's family planning programme is to promote the health of mothers, children, and their families. The aim of this follow-up study was to assess contraceptive practices in the target population 5 years after the 2010 follow-up study and to identify future programme needs.

Consumption hazards of cattle liver infected with Fasciola spp.: II. Experimental study on rats.

This study evaluated and revealed the consumption hazards of cattle liver infected with Fasciola spp. and revealed its effects on the serum estimation of liver enzyme (ALT) on experimental rats. A total of42 Wister albino rats were classified into 7 groups.

Multiproperty empirical isotropic interatomic potentials for CH4-inert gas mixtures.

An approximate empirical isotropic interatomic potentials for CH4-inert gas mixtures are developed by simultaneously fitting the Exponential-Spline-Morse-Spline-van der Waals (ESMSV) potential form to viscosity, thermal conductivity, thermal diffusion factors, diffusion coefficient, interaction second pressure virial coefficient and scattering cross-section data. Quantum mechanical lineshapes of collision-induced absorption (CIA) at different temperatures for CH4-He and at T = 87 K for CH4-Ar are computed using theoretical values for overlap, octopole and hexadecapole mechanisms and interaction potential as input. Also, the quantum mechanical lineshapes of collision-induced light scattering (CILS) for the mixtures CH4-Ar and CH4-Xe at room temperature are calculated.

Contributions of multipolar polarizabilities to the isotropic and anisotropic light scattering induced by molecular interactions in gaseous methane.

The binary isotropic and anisotropic collision-induced light scattering spectra of gaseous methane at room temperature are analyzed in terms of a recent ab initio intermolecular potential and interaction-induced pair polarizability trace and anisotropy models, using quantum line-shapes computations. The translational spectra at relatively low frequencies are determined largely by the effects of bound and free transitions. At intermediate frequencies the spectra are sensitive to both the attractive part of the potential and the short-range part of the polarizability trace and anisotropy.

The influence of naringin on the oxidative state of rats with streptozotocin-induced acute hyperglycaemia.

The effect of various doses (0, 10, 20, 40, or 80 mg/kg body weight) of naringin (a citrus flavonone) was studied on streptozotocin (STZ)-induced hyperglycaemic rats to evaluate the possible hypoglycaemic and antioxidant activity of naringin in diabetes. In comparison to the normoglycaemic group the treatment of rats with a single dose of STZ (65 mg/kg body weight) only revealed a significant increase (P < 0.05) in plasma hydrogen peroxide (H2O2) by 230%, increased the thiobarbituric acid reactive substances (TBARS) as index of the lipid peroxidation level by 69%, while total antioxidant activity was decreased by 36%, with a consistent significant decrease (P < 0.

The role of porto-systemic shunts in the specific humoral immune response in patients with schistosomal hepatic fibrosis.

The present study was devoted to elucidate the role of collaterals (porto-systemic shunts) in the specific humoral immune response to schistosomal soluble egg antigen (SEA) in patients with schistosomal hepatic fibrosis (SHF). Twenty five patients with SHF with collaterals, ten patients with SHF without collaterals and twenty healthy control subjects constituted the material of this study. In vivo and in vitro tests for humoral immunity to SEA included serum immunoglobulins estimation, immediate intradermal test, indirect haemagglutination test and determination of B lymphocytes count in peripheral blood.
