Teachers can influence the complex process of learning in education, in general, and in second/foreign language (L2) learning in particular. In this light, understanding the factors influencing teachers’ pedagogical success can help L2 teachers achieve more effective teaching. This study then investigated the role of spiritual intelligence (SI) in L2 teachers’ pedagogical success. In so doing, ...

Subtle structural details of siliceous zeolites are probed by using two-bond scalar (J) coupling constants to characterize covalently bonded Si–O–Si site pairs and local framework order. Solid-state two-dimensional (2D) Si{Si} NMR measurements and first-principles calculations of J(Si–O–Si) couplings shed insights on both the local structures of siliceous zeolites Sigma-2 and ZSM-12, as well as...

background: ultrasmallsuperparamagnetic iron oxide (uspio) nanoparticles are used as blood pool contrast agent for magnetic resonance angiography and perfusion imaging. our aim in this study was to investigate the effect of the two coating types of iron oxide nanoparticles on the relationship between nanoparticles concentration and signal intensity (si) in t1-weighted mr images.   methods : dif...

Thermally induced phase transformation of Si-III/Si-XII zones formed by nanoindentation has been studied during low temperature 200 T 300 °C thermal annealing by Raman microspectroscopy and transmission electron microscopy. Two sizes of spherical indenter tips have been used to create substantially different volumes of phase transformed zones in both crystalline c-Si and amorphous silicon a-Si ...

AIM In order to search for new biological activities of Kampo medicines and their constituent plant extracts, we investigated whether they protect the cells from the cytotoxicity induced by UV irradiation and human immunodeficiency virus (HIV) infection. MATERIALS AND METHODS Anti-UV/HIV activity (SI value) was evaluated as the ratio of the CC(50) (concentration that reduced the viable cell n...

In order to study the effects of different salinity levels on turnip (Brassica rapa L.), an investigation was conducted at Yasouj University, Iran, in 2010. The effects of four salinity levels including 1.92, 9.87, 19.6 and 21.94 ds m-1 (20:1 ratio of NaCl: CaCl2 in Hoagland solution) on germination, vegetative and maturity stages of turnip (Baherghan landrace) were investigated. The results re...

Aluminum and silicon are usually abundant in the soil and most plants are affected by them. Therefore, in the present study, the effect of the interaction of Si (0 and 2 mM) and low concentrations of Al (0, 50, 100, and 150 µM) on some physiological parameters of Zea mays var. Merit were investigated and were analyzed by cluster heatmaps for better interpretation of results. Results showed that...

Analyzing variations in silicon (Si) isotopes can help elucidate the biogeochemical Si cycle and Si accumulation processes of higher plants. Importantly, the composition of Si isotopes in higher plants has yet to be studied comprehensively and our knowledge of the distribution of Si isotopes in higher plants lags behind that of Si isotopes in marine organisms, such as diatoms. In the present st...

background:  nowadays mri examinations have been widely used in clinical applications for many diagnoses. the use of contrast agent in mri improves lesion detection and characterization and causes more accurate diagnosis.  objectives: the aim of this study was comparing to optimal dose of magnevist contrast agent in modified t1w se (spin echo), t1w fse (fast spin echo) and t1w gre (gradient ech...
