The low-energy behavior of the astrophysical S-factor for E1 direct radiative captures a(p,γ)b leading to loosely bound final states (b=a+p) is investigated. We derive a first-order integral representation for S(E) and focus on the properties around zero energy. We show that it is the competition between various effects, namely the remnant Coulomb barrier, the initial and final centrifugal barr...

thin films of binary bi 0 -teo and bi 0 -v 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. the optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a perkin-elmer uv/vis spectrophotometer. it is found that the value of n=3/2 in the davis-mott equation is best fitted for the fundamental absorption edge for the...

BACKGROUND Lopinavir/ritonavir (LPV/r) is an effective and commonly used protease inhibitor in HIV-infected adolescents. Previous data showed high plasma concentrations of LPV in Thai patients. This study determined the pharmacokinetic (PK) parameters of a low-dose LPV/r tablet (70% of standard dose) in HIV-infected Thai adolescents. METHODS A total of 24 adolescents on LPV/r-containing HAART...

We consider the Turing degrees of prime models of complete decidable theories. In particular we show that every complete decidable atomic theory has a prime model whose elementary diagram is low. We combine the construction used in the proof with other constructions to show that complete decidable atomic theories have low prime models with added properties. If we have a complete decidable atomi...

BACKGROUND Beriberi is endemic in South-east Asia. Diagnosis is based on clinical findings, but correlation of clinical features with blood thiamine concentrations is uncertain. OBJECTIVES To investigate in tachypnoeic Cambodian infants the correlation between whole blood thiamine diphosphate (TDP) concentrations, clinical findings and blood TDP levels after therapy. METHODS Infants hospita...

Selenium (Se) at high concentrations can cause toxic effects in plants, whereas at low concentrations it enhances resistance to certain abiotic stresses. The possible mechanisms of the Se-enhanced tolerance of plants to salinity stress remain elusive. In this work, effect of Se supplementation at 0, 0.1, 1 and 10 mg l-1 sodium selenate was studied in Lallemantia iberica plants subjected to salt...

OBJECTIVE The study aimed to assess the possible systemic effects of intratympanic dexamethasone (IT-Dex) on the hypothalamic-pituitary-adrenal (HPA) axis, inflammation, and bone metabolism. DESIGN A prospective cohort study including 30 adult patients of a tertiary referral ENT clinic treated with 9.6 mg IT-Dex over a period of 10 days was carried out. METHODS Effects on plasma and salivar...

the adsorption ability of miswak (salvadora persica l.) waste was investigated for the removalof common heavy metals; pb(ii), cu(ii), ni(ii) and cd(ii), from aqueous systems. the miswak mainlyconsists of saponins, tannins, silica and resin, which are accounted for the removal of heavy metal ions fromaqueous systems. the effects of various parameters, such as solution ph, contact time, initial c...
