A double-stranded RNA (dsRNA)-specific modification activity from Xenopus oocytes and human cells dsRNA modifier) converts adenosine residues present in dsRNA to inosines. The function of the dsRNA modifier is unknown, although it has been suggested that it may be part of the cellular antiviral response. We investigated the relationship between the activity of the dsRNA modifier, viral infectio...

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...

background: the dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...

handling of endodontic sealers is greatly dependent on their elasticity and flow ability. we compared the viscoelastic properties of three root canal sealers.ah plus (dentsply, de trey, konstanz, germany), endofill (dentsply hero, petrópolis, rio de janeiro, brazil) and ah26 (dentsply, de trey, konstanz, germany) were mixed according to the manufacturers' instructions. the resulted pastes were ...

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...

In this paper we investigate the transient shear rheology of a polypropylene containing long fibers (2.75 to 11 mm, L/D > 150) and short fibers (1 mm, L/D < 50). The objectives of this work are to determine the relationship between stress growth and relaxation behavior of fiber orientation and determine the feasibility of extending Doi’s theory for the rheology of rod-like molecules to fiber re...

However, the use of the term parahemorheology has been criticized, because the prefix para implies that the rheology of fluids and structures in the perivascular spaces is secondary and less important than that of the vessel-blood organ. It is also imprecise, once it does not refer to the fluids and structures being considered. By contrast, the term perihemorheology implies the rheology of flui...

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...
