the present study seeks to determine the effect of explicit instruction of metacognitive strategies on iranian high school students’ reading comprehension ability. it also attempts to investigate the relationship between the learners reading comprehension and metacognitive strategies. furthermore, the study investigates whether iranian efl female high school students are high, medium, or low me...
The Coulomb dissociation (CD) of 8B has emerged as a landmark testing ground of the very method of CD for measuring the cross section of the low-energy 7Be(p, γ )8B direct capture (DC) reaction. Recent claims of evidence of slope difference between CD and DC results are critically examined. We include all relevant RIKEN2 data and all previously published DC data, and we examine the extracted so...
Range suitability and its grazing capability are the most important criteria in rangeland analysis and monitoring. Determination and monitoring of factors affecting on range suitability and diagnosis of them are important .All range ecosystem components affect range suitability. Which among them physical and vegetational factors, forage production, water resources and sensitivity to erosion wer...
this research is a study on indicators of listening instruction in iranian english as a foreign language (efl) curriculum at guidance school and high school educational levels. this thesis aims at determining: a) the indicators of listening instruction at guidance school and high school efl curriculum. b) the indicators of listening instruction in irans guidance school and high school efl curri...
INTRODUCTION High tibial osteotomy remains a useful procedure for delaying total knee arthroplasty for young patients with unicompartimental medial osteoarthritis of the knee. The tibial posterior slope is essential for both ligament function and knee kinematics. Even though many articles were published in the literature, the long term influence of open wedge high tibial osteotomy on the poster...
correct estimates of the risk of erosion at improve land management advice plays an important role. in this study, erosion risk zoning in the kan basin with area about 20571 ha in the northwest of tehran by using the experimental model mpsiac and geographic information system (gis) were investigated and by using the base maps and gis, layers of information were prepared. after collecting, prepa...
soil slopes are sometimes curved in plan rather than being straight. this curvature,especially when it is convex, decreases the bearing capacity of the slope. finite element methodhas been used here in this research to investigate the reducing effect of curvature on bearingcapacity of a slope. failure of soil has been assumed to be according to mohr-coulomb criteria;but the flow rule of the soi...
Intelligent Forecasting Method for Slope Stability Estimation by Using Probabilistic Neural Networks
The purpose of this article is to demonstrate the application of probabilistic neural networks (PNNs) as a classification tool in the slope stability estimation. PNNs are applied to estimate slope stability according to the slope geometric shapes and soil mechanical parameters. Unlike other neural network training paradigms, PNNs are characterized by high training speed and their ability to pro...
Astracantha adscendens is an endemic species in Iran growing on alpine and above alpine timberline habitats on the Zagross Mountain Range. These habitats are characterized by steep slopes, heavy snowfalls and long ice formation periods. The present study was carried out in Chelgerd, Bakhtiari, and Fereidan, Isfahan. Slopes, elevation above sea-level, and magnetic north azimuth were measured. Th...
