background and aims: osteoarthritis is one of the most common arthritis in elderly. we evaluated to compare the effect of topical application of eugenia caryophylata extract and topical diclofenac in primary knee osteoarthritis.methods: this randomized double-blind clinical trial study was carried out upon 105 patients with primary knee osteoarthritis. patients were selected randomly and divide...

To address the challenge of optimizing placement actuators on an asymmetric spacecraft continuum system, this paper develops a rigid–flexible electromechanical coupling dynamic model that integrates interactions among rigidity, flexibility, and effects. The is constructed using ordinary differential equations partial (ODE–PDEs) considers effects installation position physical characteristics (m...

this paper presents the effects of different amounts of reclaimed asphalt on fatigue life of asphalt mixtures. central composite method was used to design of experiments based on response surface method (rsm). binder type (pen 60/70 and pen 85/100), reclaimed asphalt pavement (rap) content (25, 50 and 75%) and loading strain (150, 250 and 350 micro strain) were selected as independent variables...

background optimal use of the clinical examination aids physicians in identifying patients at risk for meningitis. the low specificity of the meningeal signs may be due to the presence of cervical arthritis and spondylosis. one of the most sensitive maneuvers in the diagnosis of meningitis is jolt accentuation of headache. patients and methods a descriptive research was performed on suspected a...

Tooth root crack is considered as one of the crucial causes of failure in the gearing system and it occurs at the tooth root due to an excessive bending stress developed in the root region. The modern power transmission gear drives demand high bending load capacity, increased contact load capacity, low weight, reduced noise and longer life. These subsequent conditions are satisfied by the aid o...

The main goal of the present study is testing asymmetric risk pricing and comparing it with pricing of traditional risk measures in Tehran Stock Market. Accordingly, a sample consisting of 101 companies listed in Tehran Stock Market during 2002-2013 went under investigation. In order to test asymmetric risk pricing, regression model of panel data was applied. The results revealed a positive and...

The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...

in this study to determine whether spine stiffness is predictive of clinical results after lumbar spinal fusion for spinal stenosis, a total of 78 patients were measured intraoperatively with kocher clamp manual distraction technique to determine motion segment stiffness then spinal fusion was performed for any loose segment. ‎statistical analysis revealed that stiffness measurement correlate w...

spherical equivalent (se) has not been linked to increased cardiovascular morbidity. methods: 132 hungarian twins (age 43.3±16.9 years) underwent refraction measurements (huvitz mrk-3100 premium autorefractokeratometer) and oscillometry (tensiomed arteriograph). results: heritability analysis indicated major role for genetic components in the presence of right and left se (82.7%, 95%ci, 62.9 to...

The design of intersecting nodes in high-rise oblique mesh structures is a critical issue. existing research on the meshes mainly focuses plane and monotonic axial compression loads. cannot consider contribution node’s out-of-plane angle floor beam to stiffness actual structures. In this paper, numerical analysis using ABAQUS was conducted investigate mechanical performance space (OMSIN) under ...
