one of the main principles of resistance economy, is to support domestic production and limiting imports, especially in sectors where there is the possibility of import-substituting production .this requires adjustment of exact trade policies,and to achieve this, identifying the structure of imports demand function and also price and income elasticity of import demand is necessary.this necessit...

PURPOSE To elucidate preventive effects of high molecular weight hyaluronan (HMWHA) on the joint capsule of immobilized knees in rats. MATERIALS AND METHODS Unilateral knee joints of rats were immobilized with an internal fixator. Either 50 μl of HMWHA (Im-HA group) or 50 μl of saline (control group) was administered intra-articularly once a week after surgery. Sagittal sections were prepared...

In cognitive networks, the cognitive radio users can share spectrum resource with the primary user while ensuring the normal communication of primary user. In addition, next generation wireless systems needs to provide flexible transmission rate to each terminal. In this paper, a utility-based game-theoretic model is proposed to study the joint power and rate control problem in spectrum underla...

BACKGROUND Disruption of the lymphatic circulation through breast carcinoma-associated axillary lymph node dissection, with or without radiation therapy, reportedly is the most common cause of lymphedema in developed countries. There is no cure for breast carcinoma-associated lymphedema. Although intermittent pneumatic compression (IPC) has been acknowledged as a potential component of the mult...

To optimize the cost and performance of complex cloud services under dynamic requirements, workflows and diverse cloud offerings, we rely on different elasticity control processes. An elasticity control process, when being enforced, produces effects in different parts of the cloud service. These effects normally evolve in time and depend on workload characteristics, and on the actions within th...

Elasticity is the foundation of cloud performance and can be considered as a great advantage and a key beneNt of cloud computing. However, there is no clear, concise, and formal deNnition of elasticity measurement, and thus no ePective approach to elasticity quantiNcation has been developed so far. Existing work on elasticity lack of solid and technical way of deNning elasticity measurement and...

Optimal load of mobile robots, while carrying a load with predefined motion precision is an important consideration regarding their applications. In this paper a general formulation for finding maximum load carrying capacity of flexible joint mobile manipulators is presented. Meanwhile, overturning stability of the system and precision of the motion on the given end-effector trajectory are take...

Anorexia nervosa (AN) is associated with gut and non-gut symptoms e.g. orthostatic intolerance and fatigue syndromes. Elsewhere, joint hypermobility has been found in non-anorexic populations who have gut symptoms, orthostatic intolerance or fatigue syndromes. We therefore postulated that joint hypermobility may be a feature of AN.Patients from an inpatient Eating Disorders Unit and their first...
