this paper tries to systematically survey, with taking theoretical view on geomorphic basin and its changes into account. the purpose of this research is to determine the balance and stability of geomorphic basins from the past to present and then to future. consequently, it tries to determine the balance between energy and input-output materials for example (rainfall , solar radiation, tectoni...

this paper employs a multivariate dynamic conditional correlation garch model, which is developed by engle (2001, 2002), to detect the timing and nature of changes in the comovement between iranian output and prices for the periods after iran–iraq war , known as imposed war . the results showed that there is a weak correlation between output and prices after imposed war and  varies periodically...

OBJECTIVE To determine accurately the relative output factors, defined as the ratio of the nominal dose rate for a given collimator to that of the 60-mm collimator. This is particularly important for radiosurgical treatment of functional disorders, such as trigeminal neuralgia, in which a single large radiation dose is delivered to the target with a small collimator, such as the 5-mm collimator...

The purpose of this study was to assess the cultural invariance of the Extended Objective Measure of Ego-Identity Status (EOM-EIS) Questionnaire across three ethnic groups (African-Americans, Caucasians, and Latinos). The total sample consisted of 289 undergraduates from a comprehensive doctoral university in the Southeastern United States. Results of the chi-squared test of goodness-of-fit ind...

Abstract. The article focuses on economic productivity and have stressed the theory of marginal utility (productivity). In modern researches such aggregate indicators as a total factor multifactor prevail. Total Factor Productivity is measured by combining effects all there sources used in production goods services (labour, capital, materials, energy, etc.) dividing it into output. Multifactor ...

A technique used to assess relative performance in a multiple input–output framework is data envelopment analysis (DEA). In basic DEA models, an entitymay show its best performanceby selecting input and output factor weights different from those selected by the other entities in thesample. Hence, when usingbasic DEAmodels, divergence of weighting schemesacross the assessedentitiescannot beruled...

where i, j, and t are firm-, industry-, and time-specific subscripts. Yit is the output of firm i in year t in the form of total sales, and Y j is the corresponding geometric mean in industry j. xit denotes the use of factor z. We consider three factors of production, labor, capital, and material input costs. Labor input is measured by the total wage bill, capital by gross fixed assets, and mat...

To find out if atrial natriuretic factor plays a part in the control of urine output during the initiation alone or throughout postnatal diuresis in neonates with respiratory distress syndrome, atrial natriuretic factor concentrations and clinical and renal variables were measured prospectively three times during the first three days of life in 13 premature infants. Atrial natriuretic factor co...

Synthetic gene regulatory networks show significant stochastic fluctuations in expression levels due to the low copy number of transcription factors. When a synthetic gene network is allowed to regulate a downstream network, the response time of the regulating transcription factors increases. This effect has been termed "retroactivity". In this article, we describe a method for estimating the r...
