abstractthis study aimed to determine the relationship between l2 learners' autonomy and their cognitive style focusing on reflectivity. it was conducted with 140 iranian m.a. efl learners from department of english at islamic azad university of najafabad. in order to have a homogeneous sample, the second version of quick placement test (qpt) was administered. then, 85 lower and 50 higher profi...

Surface reflectivity effects on coherent backscattering have been studied by using variable-reflectivity mirrors at the sample surface. Photon-transport parameters obtained from coherent backscattering were found to be significantly improved by using current theoretical models for samples with high surface reflectivity.

results three hundred patients were eligible for the study. after 1 month, 62% of patients (186 patients) reported good pain relief [95% confidence interval (ci) 0.53, 0.7]; 8.6% (26 patients) reported excellent pain relief (95% ci 0.07-0.09); 20. 4% (61 patients) reported poor pain relief (95% ci 0.18-0.22), and 9% (27 patients) reported no pain relief (95% ci 0.08-0.099). the average pain num...

A method for producing a radar-reflectivity map of the polar regions of the Moon or a planet from polar orbit with only the frequency shift of the reflected signals is described and simulated. A Radon transform of the reflectivity is obtained during multiple passes over the pole. Inversion of this Radon transform enables a map of radar reflectivity to be synthesized.

SUMMARY OF BACKGROUND DATA The association between the facet tropism and the development of lumbar disc herniation has been studied; however the results remain controversial. OBJECTIVE To determine the association between the facet tropism and the development of lumbar disc herniation. STUDY DESIGN A cross-sectional study. MATERIAL AND METHOD MRI of 34 patients with lumbar disc herniation...

OBJECTIVE To study the characteristics of the reflectivity of the cystoid spaces and serous retinal detachment (SRD) on spectral-domain optical coherence tomography (SD-OCT) and the correlation with fluorescein findings in diabetic macular edema (DME). DESIGN Retrospective, observational, cross-sectional study. PARTICIPANTS Consecutive 134 eyes of 114 patients with clinically significant ma...

BACKGROUND AND PURPOSE The prevalence of facet joint signal change in acute/subacute lumbar vertebral body compression fractures is unknown. We hypothesized that facet joint signal change on MR imaging is more common in facet joints associated with an acute/subacute lumbar compression fracture than those associated with normal vertebral bodies or ones that have a chronic compression fracture. ...
