We discuss the observational status of the interstellar lithium isotopic ratio and its significance with respect to the galactic evolution of lithium. Based on invited talks given at: ESO/EIPC Workshop on “Light Elements Abundances”, Isola d’Elba, Italy, May 22–28, 1994 ESO Workshop on “Science with the VLT”, Garching, Germany, June 28 – July 01, 1994 IAU General Assembly, Joint Discussion 11, ...

Intestinal bacteria play a key role to change the properties of drugs or herbal components, including therapeutic role, toxicity and pharmacokinetic behaviour. The present study aims to investigate the role of intestinal bacteria in changing the inhibitory potential of herbal components towards drug-metabolizing enzymes (DMEs) through comparing the inhibition of UDP-glucuronosyltransferase (UGT...

It has been predicted that dilepton production may be used as a quark-gluon plasma probe. We calculate the rapidity distributions of thermal dileptons produced by an evolving quark-gluon plasma assuming a longitudinal scaling expansion with initial conditions locally determined from the hadronic rapidity density. These distributions are compared with Drell-Yan production and semileptonic charm ...

Recent studies have demonstrated that many galaxy clusters have luminosity functions (LFs) which are steep at the faint end. However, it is equally clear that not all clusters have identical LFs. In this paper we explore whether the variation in LF shape correlates with other cluster or environmental properties.

Complexes of benzo-15-crown-5 macrocycle with Li+ and Cs+ ions were investigated by 7Li and 133Cs NMr in a number of nonoqueous solutions. The resulting 1:1 complex with Li+ ion was found to be much more stable than that with Cs+ ion. With the exception of pyridine solutions the stabilities of the complexes varied inversely w...

This study is about Complexes of Li doped silicon carbide nanotube with Thymine and Cytosine ingas phase and aqueous solutions. Li doped silicon carbide nanotube and its pyrimidine nucleobasecompounds were first modeled by Quantum mechanical calculations in gas phase and in water.Calculated binding energies indicated the stronger ability of thymine to functionalize silicon carbidenanotube than ...

to compare the effects of topiramate versus valproate sodium as an add-on therapy to a combination of lithium and risperidone (li+ris) on body weight and serum lipid profile in children and adolescents with bipolar disorder.in a single-blind randomized clinical trial, thirty children and adolescents with bipolar disorder type i in the manic or mixed phase, treated with the combination of li+ris...

the granites south of mashhad are located in the north-east of iran and occur in the suture zone between the binalud and kopeh dagh areas. these s-type granites are peraluminous with an upper triassic age and include intersecting pegmatites. these pegmatites are homogenous and show simple mineralogical combinations which include k-feldspars (microcline and orthoclase), plagioclase, quartz, mica...

This numerical study demonstrates that Doppler redshift exists in the reflected spectrum of a few-cycle pulse, propagating through a dense medium. It manifests itself in two different forms, a sharp low-frequency spike (LFS) located at the red edge of the reflected spectrum and a relatively broader redshift near the carrier frequency. With the variation of the laser and medium parameters, the d...
