objective: the study aimed to evaluate the effectiveness of laparoscopic ovarian drilling (lod) on ovulation and restoration of menstrual cycles andpregnancy. materials and m ethods : this cross sectional study was conducted on 81 consecutive polycystic ovarian syndrome (pco) patients whom were referred to avesina infertility clinic during 2003-2006. exclusion criteria were tubal and male fac...
Abstract Nowadays, bypassing agents such as recombinant activated factor VII (rFVIIa) and activated prothrombin complex concentrates (aPCC) are used to treat bleeding episodes in the Hemophilia patients with inhibitors. AryoSeven® is an Iranian biogeneric rFVIIa with homogeneity of efficacy and the nature to NovoSeven in a comparative trial. The current clinical trial aimed to evaluate the cost...
Direct torque control (DTC) is a fast and simple torque control method for induction motor without speed sensor. Conventional AC-DC-AC converter has a large DC link capacitor and low power factor in the input power line. In the matrix converters the DC link capacitor can be reduced and the unity input power factor can be obtained. In this paper a new method for direct torque and stator flux con...
A microwave domain characterization approach is proposed to determine the properties of high quality factor optical resonators. This approach features a very high precision in frequency and aims to acquire a full knowledge of the complex transfer function (amplitude and phase) characterizing an optical resonator using a microwave vector network analyzer. It is able to discriminate between the d...
In this paper, we have proposed a shell type dielectric microsphere resonator in order to enhance its quality factor. In this work we have assumed that the radius of dielectric microsphere is 12μm and that the interior metal layer radius is 11.5μm. We have obtained analytic equations for Vector potentials, characteristic equation, quality factor, resonance frequency and resonance location of TE...
Background: If a managers try for further income or productivity so they must attentive their staff incentive. One of the most issue in the management process is that managers can distinguish strength of staff but they can't determine their weakness . ACHIEVE model present seven factors ( ability, clarify, help, incentive , evaluation, validity , environment ) that effective to staff performanc...

Operating a device at high power and high frequency is a major problem because wall losses greatly reduce the efficiency of the device. In the present communication, authors analytically analyzed the dependence of ohmic/RF efficiency, the fraction of output power with respect to the total power generated, of gyrotron cavity structure on the conductivity of copper for the second harmonic TE0,6 m...
Worldwide, haemophilia is the most common hereditary bleeding disorder. The incidence of haemophilia B, however, is considerably less than haemophilia A and consequently appears to have received less attention in the research literature. This article aims to summarise the available evidence documenting the patient and economic burden associated with haemophilia B and current methods of disease ...
