The Interstellar 7 Li / 6 Li Ratio

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...

Traffic measurement provides critical real-world data for service providers and network administrators to perform capacity planning, accounting and billing, anomaly detection, and service provision. In many measurement functions, statistical methods play important roles in system designing, model building, formula deriving, and error analyzing. One of the greatest challenges in designing an onl...

LI-YORKE CHAOTIC GENERALIZED SHIFT DYNAMICAL SYSTEMS

‎In this text we prove that in generalized shift dynamical system $(X^Gamma,sigma_varphi)$‎ ‎for finite discrete $X$ with at least two elements‎, ‎infinite countable set $Gamma$ and‎ ‎arbitrary map $varphi:GammatoGamma$‎, ‎the following statements are equivalent‎: ‎ - the dynamical system $(X^Gamma,sigma_varphi)$ is‎ Li-Yorke chaotic;‎ - the dynamical system $(X^Gamma,sigma_varphi)$ has‎ an scr...
