Background: Assessment of AMH cut-off levels in serum and in follicle fluid (FF) for patients with (group 2, n=34) and without (group1, n= 96) endocrinological risk factors, such as ovarian hyperstimulation syndrome (OHSS) and polycystic ovary syndrome (PCOS), is clinically useful in optimising the treatment protocol. Materials and Methods: AMH was analysed in serum and FF of 130 infertile pati...

The dynamics of a one-dimensional slowly modulated, nearly monochromatic localized wave train in deep water is described by a one-dimensional soliton solution of a twodimensional nonlinear Schrödinger (NLS) equation. In this paper, the instability of such a wave train with respect to transverse perturbations is examined numerically in the context of the NLS equation, using Hill’s method. A vari...

The aim of this study was to assess the effect of filtering techniques on the time-domain analysis of the ECG. Multi-lead ECG recordings obtained from chronic atrial fibrillation (AF) patients after successful external cardioversion have been acquired. Several high-pass filtering techniques and three cut-off frequency values were used: Bessel and Butterworth four-pole and two-pole bidirectional...

Objective: The present this study aimed to determine the proper cut-off points for waist circumference (WC), Waist to height ratio (WHtR) and body mass index (BMI) for early predicting of metabolic syndrome among inactive college students. Materials and Methods: In this cross-sectional study, 126 males (age 20.33±1.71) and 63 females (age 20.36±1.72) with inactive lifestyle parti...

By using a Wiener-Hopf approach, an analytical description is derived of the scattered field of a harmonic sound wave coming out of an open ended annular duct (a semi-infinite cylinder inside of which, coaxially, is a doubly infinite hub), submerged in a subsonic, coaxial, uniform mean flow. The possibility of vortex shedding from the pipe exit edge is included. Explicit expressions are given f...

background: risk of malignancy index (rmi) is the best method for discriminating benign and malignant pelvic masses. the aim of this study was to determine the rmi for preoperative evaluation of pelvic mass. methods: this study was performed on 182 women with adenexal mass referred to yahyahnejiad hospital of babol university of medical sciences in iran from 2007 to 2009.the sensitivity, specif...

In the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. Since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. Different goals may be used for determining optimum cut-off grade. One of...

Substantial variability is seen when thickness measurements using conventional ultrasonic time of flight are carried out on rough surfaces; this makes it difficult to estimate corrosion rates the mechanism leads surface roughness. It has been shown that guided wave cut-off frequencies (through resonance frequencies) can be done at much lower than gauging for same minimum resolution. The frequen...
