there are different processes to form new words in every language, including compounding, derivation, inflection, etc. in compounding, two lexical stems form a compound. in derivation and inflection, new words are coined by affixation or some phonetic changes. this kind of affixation is applied on the simple or compound stem. here our compound stem is a bound compound stem, consisting of a noun...
To provide a framework for component-based technology, we combine the bottom-up analysis of three specific systems with top-down conceptual models of interaction. CORBA/OpenDoc, COM/OLE/ ActiveX, and Java/JavaBeans concretely illustrate emerging principles of component and document design, such as the events-properties-methods model. They support components with visual, interactive listening me...
superset exercise is a mode of strength training characterized by limited rest intervals between sets. our study aims to investigate plasma ck, igf-i, and gh responses to reverse and compound supersets. fourteen trained men (bmi= 23.25±2.59; age= 24±2.32) participated in our study. subjects were designated to two groups of 7 each, and a cross design was used in exercise performance. exercises w...
Achillea tenuifolia Lam (Asteraceae) afforded a methanolic extract from which after fractionation in solvents with different polarities two known flavones 3’, 5- dihydroxy- 4’, 6, 7- trimethoxy flavone (eupatorine, compound 3), 5- hydroxy- 3’, 4’, 6, 7- tetramethoxyflavone (compound 4), besides stearic acid (compound 1 ), lupeol (compound 2), daucosterol (β- sitosterol 3-O- β- D- glucopyranosid...
A New Approach to Simultaneously Enhancing Heavy Oil Recovery and Hindering Asphaltene Precipitation
A new chemical compound is developed at Petroleum University of Technology to enhance the recovery of the free imbibition process and simultaneously hinder asphaltene precipitation. The compound is tested on heavy oil samples from Marun oil field, Bangestan reservoir. The effects of the chemical compound on viscosity, hydrocarbon composition, and average molecular weight of the heavy oil are in...

The charge-transfer (CT) together with the polarization energy appears at second and higher orders in symmetry-adapted perturbation theory (SAPT). At present there is no theoretically compelling way of isolating the charge-transfer energy that is simultaneously basis-set independent and applicable for arbitrary intermolecular separation. We argue that the charge-transfer can be interpreted as a...
A new bacterial nitroreductase has been identified and used as a biocatalyst for the controllable reduction of a variety of nitroarenes with an electron-withdrawing group to the corresponding N-arylhydroxylamines under mild reaction conditions with excellent selectivity (>99%). This method therefore represents a green and efficient method for the synthesis of arylhydroxylamines.
In the reaction between equimolar amounts of horseradish peroxidase and chlorite, the native enzyme is oxidized directly to Compound II (Hewson, W.D., and Hager, L.P. (1979) J. Biol. Chem. 254, 3175-3181). At acidic pH but not at alkaline values, this initial reaction is followed by oxidation of Compound II to Compound I. The highly pH-dependent chemistry of Compound II can be readily demonstra...
