Natural products – Discover their challenge and beauty Natural products have always been among the most fascinating objects of the practicing chemist. In fact, in many definitions of chemistry the isolation, purifi cation and structural elucidation of natural products plays a central role. The his t[r]

PART 1 THE BASIC UNITS CÁC BÀI KHÓA CƠ BẢN UNIT 1: CHEMISTRY AND ITS BRANCHES Chemistry is the science of substances of their structure, their properties, and the reactions that change them into other substances. The study of chemistry may be divided into the following branches: General chemist[r]
Substantial deviations from purchasing power parity (PPP) occur in the short run: the same basket of goods generally does not cost the same everywhere at all times. • These shortrun failures of the monetary approach prompted economists to develop an alternative theory to explain exchange rates[r]
In the past three decades there have been major advances in our understanding of the chemistry and function of nutritional components. This has been enhanced by rapid developments in analytical techniques and instrumentation. Chemists, food scientists and nutritionists are, however, separated by div[r]

The paper is an overview on an algebraic approach to domains of linguistic variables and some first applications to show the applicability of this new approach. In this approach, each linguistic domain can be considered as a hedge algebra (HA for short) and based on the structure of HAs, a notion of[r]
We establish formulas for computingestimating the Fr´echet and Mordukhovich coderivatives of implicit multifunctions defined by generalized equations in Asplund spaces. These formulas are applied to obtain conditions for solution stability of parametric variational systems over perturbed smoothbound[r]
Bioassay guided fractionation led to the isolation of a new triterpene glycoside, holothurinogenin B (1) along with three known compounds, holothurin B (2), holothurin A (3), and holothurin A2 (4), from the methanol extract of the Vietnamese sea cucumber Holothuria scabra. Their structures were dedu[r]
Several optimization schemes have been known for convex optimization problems. However, numerical algorithms for solving nonconvex optimization problems are still underdeveloped. A progress to go beyond convexity was made by considering the class of functions representable as differences of convex f[r]

Crystalline perovskite La0,67−xLi3xTiO3 with x = 0.06, 0.11 and 0.15 were prepared by solid-state-solution reactions at 1350◦C from TiO2, La2O3 and Li2CO3. Crystalline structure of these compounds was analyzed by XRD method. The ionic conducting property of La0.67−xLi3xTiO3 was characterized on Auto[r]
