an amoniumvanadate plus sodium molybdate mixed modifier graphite furnace atomic absorption spectrometric method has been developed for determination of traces of lead in drinking water. the concentration of lead in the sample is obtained by direct comparison to linear working graph prepared from aqueous standards in the modifier medium, the results indicate the better performance of the propose...

Noun compounds, consisting of two nouns (the head and the modifier) that are combined into a single concept, differ in terms of their plausibility: school bus is a more plausible compound than saddle olive. The present study investigates which factors influence the plausibility of attested and novel noun compounds. Distributional Semantic Models (DSMs) are used to obtain formal (vector) represe...

Event nouns can lexically encode eventive information. Recently these nouns have generated considerable scholarly interest. However, little research has been conducted in their morphological and syntactic structure, qualia modification, event representing feature, and information inheritance characteristics. This study has these main findings. 1) Morphologically, the modifier and the head is ei...

To control the dispersibility of surface-modified nanoparticles in fluid, it is important to evaluate affinity between and solvents elucidate effect surface modification on at molecular level. In this study, chain length modifier solvent work adhesion Wadh was investigated for carboxylic acid-modified Al2O3/n-alkane interface by dynamics simulations using phantom-wall method. Here, we adopted h...

The importance of promising composites in modern materials science is constantly increasing. use various fillers or additives associated with their influence not only on the defining properties composite, but also physical and mechanical characteristics material. In this case, distribution additive its wetting a polymer play an important role. problem highlighted article different copper-contai...

In this paper, we perform a complete analysis of the kinetic behavior of the general modifier mechanism of Botts and Morales in both equilibrium steady states and non-equilibrium steady states (NESS). Enlightened by the non-equilibrium theory of Markov chains, we introduce the net flux into discussion and acquire an expression of the rate of product formation in NESS, which has clear biophysica...

For the management of fractured large pores in high-water-bearing reservoirs, general approach is to use transfer dissection and sealing. Conventional regulators have a limited regulating radius can only produce blocking near-well zone, which not ideal. Deep technology expand action substantially improve effect. The existing deep-dissection agent system has problems such as high cost poor effec...

The object of research is the hydrophobization a coating based on styrene-acrylic copolymer and cellulose acetate butyrate with pyrogenic silicon dioxide. hydrophobicity or hydrophilicity surface depends mainly chemical structure its roughness. A relief hydrophilic will be wetted much more easily than flat same material, vice versa – an increase in roughness hydrophobe accompanied by pronounced...

Plant and animal fibers are getting recognition from researchers academicians as a potential reinforcement for polymer composites due to their ecofriendly nature sustainability. In the present study, fabrication has been carried out on Jute Vetiver fiber reinforced Epoxy using hand lay-up technique with varying mass of in epoxy matrix modifier graphite which fixed by weight. The mechanical (ten...
