Nicotine is an alkaloid obtained from the leaves of the tobacco plant, and it is the main constituent of tobacco smoke. This review opens with physical and chemical properties of nicotine and with general considerations about the methods for determining nicotine and its metabolite cotinine. It summarises the data about acute and long-term toxicity of nicotine and also reviews its metabolism and...

The combination of epigallocatechin gallate (EGCg, a main constituent of tea catechins) with penicillin showed synergism against 21 clinical isolates of penicillinase-producing Staphylococcus aureus. Besides binding directly to peptidoglycan, the inhibition of penicillinase activity by EGCg is responsible for the synergism. EGCg inhibited the penicillinase activity in a dose-dependent fashion, ...

Whey is a by product in the process of cheese production. Composition and characteristics of whey are depending on the production technology of the end product and on the quality of the used milk. Liquid whey consists approximately 93% of water and contains almost 50% of total solids present in the milk of which lactose is the main constituent. Lactose is the main constituent of whey while prot...

Main idea: Emotion extraction from text based on Affect Analysis Model. The model was designed based on the compositionality principle, according to which we determine the emotional meaning of a sentence by composing the pieces that correspond to lexical units or other linguistic constituent types governed by the rules of aggregation, propagation, domination, neutralization, and intensification...

An implication of the spontaneous chiral symmetry breaking in QCD is that at low energy and resolution there appear quasiparticles-constituent quarks and Goldstone bosons. Thus, light and strange baryons should be considered as systems of three constituent quarks with confining interaction and a chiral interaction that is mediated by Goldstone bosons between the constituent quarks. We show how ...

once ds is abandoned in the minimalist framework and structure building is carried out by merge, multiple root syntactic objects in a single derivational step are not only allowed in principle, but must indeed be employed in some derivations in order for the extension condition to be satisfied. the crucial aspect of this theoretical model is that it permits instances of sideward movement, where...
