the construct of self-efficacy has received increasing attention in research over the past two decades. many studies have been carried out 1.3 significance of the study this study has pedagogical implications since improving students’ self- efficacy and autonomy is important for promoting actual performance on classroom academic tasks. in academic settings, it has been shown that self-effi...
BACKGROUND Obesity is a risk factor for end-stage renal disease. Renal hyperfiltration, defined as an abnormally high glomerular filtration rate (GFR), is a link in the causal chain between diabetes and chronic kidney disease. Whether obesity is associated with hyperfiltration in the non-diabetic general population, remains unresolved due to a lack of consensus regarding the definition of hyper...
AIMS Episodes of increased air pollution are associated with increases in hospital admissions for cardiovascular disease. Even modest acute phase responses are associated with increased risk of coronary heart disease. The study investigates whether induction of an acute phase response by exposure to air pollution may contribute to cardiovascular pathology. METHODS AND RESULTS A prospective co...
The purpose of this study of school-age children was to estimate prevalence and interrelationships of overweight, central adiposity, and hypertension. It included 1,070 children in kindergarten through sixth grade (67% Hispanic, 26% African American, mean age = 8.9 years). Measures included body mass index (BMI), waist circumference (WC), systolic and/or diastolic hypertension identified by mea...
Previous studies have reported inconsistent associations between maternal serum ferritin concentrations and the risk of spontaneous preterm birth (sPTB). The aim of the present study was to examine the association between Fe biomarkers, including serum ferritin concentrations, and the risk of total ( 75th percentile ( ≥ 43 μg/l) (OR 1.49, 95% CI 1.06, 2.10) and >90th percentile ( ≥ 68 μg/l) (OR...
Future fire weather conditions under climate change were investigated based on the Fire Weather Index (FWI), Initial Spread (ISI) and threshold-specific indicators in Greece. The indices calculated from datasets derived high-resolution validated simulations of 5 km. dynamical downscaled with WRF model driven by EC-Earth output for historical (1980–2004) future periods, two Representative Concen...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
Birth Size Distribution in 3,705 Infants Born toMothersWith Type 1 Diabetes A population-based study
RESEARCH DESIGN AND METHODS—This was a population-based cohort study of 3,705 infants of type 1 diabetic mothers (1,876 boys), with a gestational age of 28–43 weeks, born in Sweden between 1998 and 2007. BW and BL were retrieved from the Medical Birth Registry and expressed as SD scores (SDS). Ponderal index (PI) was calculated as BW in g/length in cm. A BW.90th and a PI,90th percentile was def...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
Abstract:Introduction: Racial and environmental differences in communities leading cause of differences in serum lipids. It can be said this study aimed in assessing percentile curves of serum lipid profile about 6-18 years old students of Birjand.Method: The present cross-sectional study was done on 4168 students of Birjand aged 6-18 years. They were classified into three age groups 6-10 and 1...
