Data contained in a 1982 paper were analyzed in terms of relevance odds of common items retrieved by searching any two content-bearing search fields. While the 1982 study compared the relative retrieval performance of 7 search fields, the present study shows that duplicate documents retrieved by the use of terms from any two of the fields would have higher odds of being judged relevant than tho...

Cooperative activation of striated muscle by calcium is based on the movement of tropomyosin described by the steric blocking theory of muscle contraction. Presently, the Hill model stands alone in reproducing both myosin binding data and a sigmoidal-shaped curve characteristic of calcium activation (Hill TL (1983) Two elementary models for the regulation of skeletal muscle contraction by calci...

abstract the aim of this survey is to compare utilization systems (cooperative, private and governmental) methods of energy consumption in soybean production and the evaluation of energy inputs effect in yield of soybean in moghan. for this purpose, the information were collected from 54 private farmers, 14 cooperative members farmers and 14 agro-industry units by questionnaire method. the maxi...

We formulate the massive overlap fermions on anisotropic lattices. We find that the dispersion relation for the overlap fermion resembles the continuum form in the low-momentum region once the bare parameters are properly tuned. The quark selfenergy and the quark field renormalization constants are calculated to one-loop in bare lattice perturbation theory. We argue that massive domain wall qua...

We present an approach for finding the overlap area between two ellipses that does not rely on proxy curves. The Gauss-Green formula is used to determine a segment area between two points on an ellipse. Overlap between two ellipses is calculated by combining the areas of appropriate segments and polygons in each ellipse. For four of the ten possible orientations of two ellipses, the method requ...

abstract a quantitative framework of combination of liner programming and cooperative game theory was used in this study to analyze and model cooperative contracts in production based on rural households' resources cooperation in firoozabad plain. revenues and costs in cooperation game theory have important rule to get agreement. transaction cost function was used in cooperative costs accountin...

this study aims at investigating the effect of using cooperative learning (jigsaw2) and traditional learning on the reading comprehension achievement. in the present study, experimental research model consisting of pre-test, post-test with a control group was applied. the sample of the study consisted of 64 participants in grade three in bonab high schools. to determine the effect of cooperativ...

despite various efforts towards empowerment of cooperatives in iran, much in agreement with this concept and strategies can not be observed. the purpose of this descriptive study was to investigate the solutions to empowering production cooperatives. the delphi technique was employed to do this study. the target population consisted of specialists in national provincial and specialists (n=15). ...
