We microscopically and mechanically evaluated the femurs of rats subjected to hindlimb unloading (tail suspension) followed by treadmill training. Female Wistar rats were randomly divided into five groups containing 12-14 rats: control I (118 days old), control II (139 days old), suspended (tail suspension for 28 days), suspended-released (released for 21 days after 28 days of suspension), and ...

Yarn tension during manufacturing has a large influence on the processing efficiency, yarn properties, and hence on fabric characteristics. In this work the dynamic tension two-for-one twister was investigated and the effect of various parameters the dynamic were studied. A test set-up unit was built to simulate the Two-for-one twister, so the effect of spindle speed, winding velocity feed pack...

Individuals that maintain pair bonds over multiple breeding attempts are often able to improve reproductive success compared to conspecifics that switch partners. However, the behavioral mechanisms driving this ‘mate familiarity effect’ are still largely unknown. We investigated whether long-standing pairs in the long-lived, socially monogamous Steller’s jay improved their coordination of movem...

Kelps are a clade of morphologically diverse, ecologically important habitat-forming species. Many kelps live in wave-swept environments and are exposed to chronic flow-induced stress. In order to grow and survive in these harsh environments, kelps can streamline (reducing drag coefficient) to avoid drag or to increase attachment and breakage force to tolerate it. We aimed to quantify the drag ...

This study aimed to predict life satisfaction based on psychological tenacity and dimensions of perfectionism in patients with coronary heart disease. To achieve the purpose of this study and testing its hypotheses, 200 people with coronary heart disease refered to Golsar hospital of Rasht, during the summer and fall of 2015 were selected.The metohd used in this study for sampling was available...

STUDY DESIGN An in vivo study on the effects of an agent for scar prevention in a dog laminectomy model. OBJECTIVE To examine the anti-adhesion properties of a thrombin-based hemostatic gelatin (FLOSEAL; Baxter International Inc., Deerfield, IL). SUMMARY OF BACKGROUND DATA Postlaminectomy dural adhesion sometimes causes symptomatic problems. Although a new type of hemostatic agent, a thromb...

In order to determine the relationship between fiber properties of yarn quality in article, experiments were conducted using a passive method mathematical planning and regression equation was obtained for each optimal parameter. Based on experiments, it found that decrease micronaire, an increase tensile strength, length uniformity, leads specific strength yarn, coefficient variation number bre...

a special class of cubic graphs are the cycle permutation graphs. a cycle permutation graph pn(α) is defined by taking two vertex-disjoint cycles on n vertices and adding a matching between the vertices of the two cycles.in this paper we determine a good upper bound for tenacity of cycle permutation graphs.

In this note, we show that one of the arguments used by Moazzami for computing the tenacity of the third Harary graph is wrong and then improve the proof. © 2014 Published by Elsevier B.V.

Fiber-reinforced composite materials have many advantages in various engineering applications when compared to traditional such as glass, metals, ceramics and unreinforced plastics. Recently, textile-reinforced composites are increasingly used industries including aerospace, construction automotive. This study aims investigate the geometric characteristics of three-dimensional (3D) woven prefor...
