PROBLEM To explore the roles of leptin, monocyte chemotactic protein (MCP)-1, and tumour necrosis factor (TNF)-α in the peritoneal fluid (PF) in the pathogenesis of endometriosis-associated infertility. METHOD OF STUDY Leptin, MCP-1, and TNF-α levels in the PF from 28 infertile women with endometriosis (study group), 23 women with fallopian-associated infertility (controls), and 24 women with...
The particle filter (PF) is a novel technique that has sufficiently good estimation results for the nonlinear/non-Gaussian systems. However, PF is inconsistent that caused mainly by loss of particle diversity in resampling step and unknown a priori knowledge of the noise statistics. This paper introduces a new modified particle filter called adaptive unscented particle filter (AUPF) to overcome th...
an artificial neural network (ann) was used to analyse the capillary rise in porous media. wetting experiments were performed with fifteen liquids and fifteen different powders. the liquids covered a wide range of surface tension ( 15.45-71.99 mj/m2 ) and viscosity (0.25-21 mpa.s). the powders also provided an acceptable range of particle size (0.012-45 μm) and surface free energy (25.54-...
BACKGROUND In clinical settings, it is important for health care providers to measure different aspects of functioning in older adults with joint pain and comorbidity. Besides the use of distinct measures, it could also be attractive to have one general measure of functioning that incorporates several distinct measures, but provides one summary score to quantify overall level of functioning, fo...
Assessment of the diet adaptation period is critical for feeding experiments in ruminants to have significant changes concerned parameters. An vitro trial was conducted investigate impact sampling at different time periods (day 0, 11, 21, and 60) determine feed treatment over ruminal fermentation parameters crossbred Karan-Fries cattle (Bos taurus) Murrah (Bubalus bubalis) heifers. Two types to...
It is a major challenge to elevate the thermoelectric figure of merit ZT of materials through enhancing their power factor (PF) and reducing the thermal conductivity at the same time. Experience has shown that engineering of the electronic density of states (eDOS) and the energy filtering mechanism (EFM) are two different effective approaches to improve the PF. However, the successful combinati...
The main goal of this paper is to present some experimental results regarding power factor (PF) and current total harmonic distortions (THDi) of some very common loads on low voltage a.c. lines i.e. the power supply of computers, monitors and TV sets. The causes of some unexpected values are investigated and some physically meaningful explanations are delivered. The impact of the output current...
When the input inductor operates in discontinuous current mode (DCM), Cuk converter can automatically achieve power factor correction (PFC) function with only a simple voltage control loop. However, conventional PFC suffers from high intermediate capacitor because of lack feedback and relatively low (PF). In this paper, using variable which varies transient rectified is proposed to enhance PF r...
Various commutation techniques, such as forced commutation, ignition angle control, and symmetrical have been developed to improve the input power factor harmonic level. However, all of these techniques will produce only one pulse per half cycle converter current, consequently, lowest order is third harmonic. A comparative study active filter converters between single PWM control has investigat...
Alternatively activated macrophages (M2 macrophages) are involved in tissue remodeling and fibrosis, but their effects on peritoneal fibrosis (PF) induced by high glucose peritoneal dialysate have yet to be fully established. In this study, PF was induced in male Sprague-Dawley rats by intraperitoneal injection with Lactate-G4.25% dialysate (20 ml/rat/day) for 4 weeks. Control rats were given a...
