2014 Starting from the Liouville equation we derive equations for density and concentration fluctuations in two-component polymeric liquids. An exact expression for the interdiffusion coefficient is obtained. As examples we consider mixtures of labelled molecules and the case of polymers solved in a low molecular weight liquid. The relation of the general formula to two widely used approximate ...

OBJECTIVE To validate a Chinese version of the Diabetes Distress Scale (CDDS). RESEARCH DESIGN AND METHODS The CDDS was derived using forward-backward translation and administered in 189 Chinese type 2 diabetic patients with evaluation of its psychometric properties. RESULTS On the basis of principal-component analysis, three factors of the 15-item version of the CDDS (CDDS-15) accounted fo...

we present a model and propose an approach to compute an approximate solution of fully fuzzy linear system $(ffls)$ of equations in which all the components of the coefficient matrix are either nonnegative or nonpositive. first, in discussing an $ffls$ with a nonnegative coefficient matrix, we consider an equivalent $ffls$ by using an appropriate permutation to simplify fuzzy multiplications. t...

Wheat is an important crop of India. Precise estimates of evapotranspiration can be obtained by multiplying crop coefficients to reference evapotranspiration using readily available climatic data. PenmanMonteith equation is adopted world wide as the most reliable and accurate method for computing reference evapotranspiration. The Food and Agriculture Organization (FAO) presented crop coefficien...

Nude mice each attached to a respirator to avoid pulmonary uptake were exposed in a glass exposure chamber to 200, 1000 or 3000 ppm of benzene, toluene or tetrachloroethylene (perclene) for 2, 4 or 6 h. The animals were killed at the end of the study and the amount of each solvent retained in the whole body was determined by gas chromatography. Skin absorption rates were calculated from the amo...

In this paper, we present an approach to measure the transliteration similarity of English-Hindi word pairs. Our approach has two components. First we propose a bi-directional mapping between one or more characters in the Devanagari script and one or more characters in the Roman script (pronounced as in English). This allows a given Hindi word written in Devanagari to be transliterated into the...

Anxiety effects on the Trail Making test (TMT), a test often used for screening for cognitive impairments, were examined in a sample of cocaine abusers in drug abuse treatment programs. A mixed race sample of 4306 subjects was drawn from electronic files of data from the Drug Abuse Treatment Outcome Study (DATOS). The DATOS was a naturalistic, prospective cohort study that collected data from 1...

This paper describes the development and evaluation of an on-road procedure, the Driving Observation Schedule (DOS), for monitoring individual driving behavior. DOS was developed for use in the Candrive/Ozcandrive five-year prospective study of older drivers. Key features included observations in drivers' own vehicles, in familiar environments chosen by the driver, with start/end points at thei...
