Experiments show high-speed spinning of many synthetic bers is accompanied by the partial crys-tallization of the initially amorphous melt. This crystallization is induced by some combination of the extensional ow, molecular orientation and extension, and temperature dependence. The crystallization of the material couples back to aaect the ber rheology, through a process of stress-hardening. Re...

the aim of this study was to design the strategic orientations model of market, brand and entrepreneurship in the food industry in iran.  the organizational decisions are not formed  in a vacuum but in the economic and cultural environmental context of each country, they are much influenced by many different factors. this study is of applied type and was conducted in two stages. first after an ...

The purpose of the current study was to investigate the contribution of upper and lower arm torsion to grasp orientation during a reaching and grasping movement. In particular, we examined how the visuomotor system deals with the conflicting demands of coordinating upper and lower arm torsion and maintaining Donders' Law of the upper arm (a behavioral restriction of the axes of arm rotation to ...

today, market orientation plays a vital role in determining customers’ needs and success of organizations. market orientation has also influenced various organizations’ measures including innovation. therefore the aim of this research is to study the role of market orientation in innovation of bodybuilding clubs of golestan province. the population of this study comprised all 170 managers of bo...

Many phenomenological models of the responses of simple cells in primary visual cortex have concluded that a cell's firing rate should be given by its input raised to a power greater than one. This is known as an expansive power-law nonlinearity. However, intracellular recordings have shown that a different nonlinearity, a linear-threshold function, appears to give a good prediction of firing r...

Creep strength of oriented orthopyroxene single crystals was investigated via shear deformation experiments under lithospheric conditions [P (pressure) = 1.3 GPa and T (temperature) = 973–1,373 K]. For the A-orientation (shear direction [001] on (100) plane), the samples have transformed completely to clinoenstatite and much of the deformation occurred after transformation. In contrast, for the...
