Abstract This study investigated the performance of jute stick charcoal (JSC) as a biosorbent for removal hexavalent chromium [Cr(VI)] from an aqueous solution. The batch adsorption experiment was conducted by influencing various experimental conditions like contact time (5–240 min), pH (2–8), initial Cr(VI) concentration (10–100 mg/L), and JSC dose (2–10 g/L). result shows that maximum (99%) f...
BACKGROUND In this study, we aimed to investigate the ability of transvaginal Doppler ultrasonography in predicting in vitro fertilization (IVF) outcome in women undergoing this procedure. MATERIALS AND METHODS In this prospective observational study, 65 infertile women underwent IVF procedure in Isfahan, during 2013-2014, were studied. The pulsatility index (PI), resistive index (RI) and pea...
To determine which is the best anthropometric index among body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR) and waist to height ratio (WHtR) in type 2 diabetic patients, we examined the relationship between these indices and cardiovascular risk factors using partial correlation analysis, chi-square test, logistic regression analysis and Receiver Operator Characteristic (...
The kinetic study of methylene blue (MB) adsorption using acid-activated spent tea (AAST) as an adsorbent from aqueous solution with the aim of comparing linear and non-linear regression analysis methods was performed at varying initial MB concentrations (10-100 mg/l). Hence, spent tea leaves, which were activated using concentrated sulfuric acid, were prepared. The physicochemical characterist...
BACKGROUND Demographic changes have led to an increase in the number of elderly frail persons and, consequently, systematic geriatric assessment is more important than ever. Frailty Indexes (FI) may be particularly useful to discriminate between various degrees of frailty but are not routinely assessed due, at least in part, to the large number of deficits assessed (from 30 to 70). Therefore, w...
OBJECTIVE To study the correlation between third-trimester serum ferritin concentration and hemoglobin and red cell indices to select the best hematologic characteristic to identify women who need iron therapy. METHODS In a prospective study, blood was drawn from pregnant women with hemoglobin above 10 g/dL, and thalassemia trait excluded at booking, at 28-30 weeks' gestation to study the cor...
Many approaches have been proposed for monitoring the eutrophication of Case 2 waters using remote sensing data. Semi-analytical algorithms and spectrum matching are two major approaches for chlorophyll-a (Chla) retrieval. Semi-analytical algorithms provide indices correlated with phytoplankton characteristics, (e.g., maximum and minimum absorption peaks). Algorithms’ indices are correlated wit...
Early detection of water stress is critical for precision farming for improving crop productivity and fruit quality. To investigate varying rootstock and irrigation interactions in an open agricultural ecosystem, different irrigation treatments were implemented in a vineyard experimental site either: (i) nonirrigated (NIR); (ii) with full replacement of evapotranspiration (FIR); or (iii) interm...
OBJECTIVE Many state trauma registries contain work-related information but are underutilized for occupational injury research/surveillance. We assessed three methods of identifying work-related injuries in the Washington State Trauma Registry (WTR). METHODS State-designated trauma facilities report traumatic injuries meeting specific inclusion criteria to the WTR. The WTR reports from 1998 t...
BACKGROUND Bone marrow examination may be required to discriminate causes of thrombocytopenia as hypoproductive or hyperdestructive. However, this procedure is invasive and time consuming. This study assessed the diagnostic value of Mean Platelet Volume (MPV), Platelet Distribution Width (PDW) and Platelet Large Cell-Ratio (P-LCR) in discriminating causes of thrombocytopenia as hypoproductive o...
