Nonstoichiometric GeSixOy glass films and many-layer structures based on them were obtained by high-vacuum electron beam vapor deposition (EBVD). Using EBVD, the GeO2, SiO, SiO2, or Ge powders co-evaporated deposited onto a cold (100 °C) p+-Si(001) substrate with resistivity ρ = 0.0016 ± 0.0001 Ohm·cm. The as-deposited samples studied Fourier-transformed infrared spectroscopy, atomic force micr...
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
Conceptual models of aquifer systems can be refined and complemented with geophysical data, and they can assist in understanding hydrogeological properties such as groundwater storage capacity. This research attempts to use geoelectrical methods, Electrical Resistivity Tomography and Induced Polarization parameters, for mapping the subsurface in alluvial fans and to demonstrate its applicabilit...
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
abstract objective: evaluating the usefulness of the triple test score (tts) in breast lesions. materials and methods: medical records of 100 cases were evaluated and tts was calculated based on of physical examination, mammography and fine-needle aspiration cytology findings. the diagnostic value of tts was assessed according to histopathology results. results: of the 23 lesions with score of ...
Abstract An electrical resistivity survey was carried out using the pole–pole configuration around Sayanokami spring area in northern part of Ito Campus (Kyushu University, Fukuoka, Japan) to study groundwater aquifer and its characteristics. A Code Division Multiple Transmission (CDMT) system used. The CDMT transmits 24 currents simultaneously measures potential responses with monitoring actua...
abstract listening is a key and main tool in second language skill and its development is of prime concern to teachers and learners. furthermore, the application of technology in language classrooms has become more commonplace in the last fifty years. computer and the internet have made foreign language materials easy to access and use. so, the present study is an attempt to examine the effec...
abstract: one of the most visited & important spaces in different countries by tourist are urban areas. the old tehran which major part is located in district 12 is historical showcase of the capital, but, its hiidden cultural attraction is not used as it should be. this thesis occasionally engage in studying the efficacy of correct installation of travel guide boards in welfare & easily acc...
A network of long-period magnetotelluric and magnetovariational data (124 sites) in the period range 9—16 to 2500—6400 s made it possible explore geoelectric structure Erth’s crust upper mantle most Dniester-Bug adjacent megablocks Ukrainian shield. Based on resistivity cross-sections along profiles (with 2D inversion), a three-dimensional matrix was created for territory limited by coordinates...
Magnetic island equilibria resulting from reconnection in magnetohydrodynamic (MHD) simulations are explored in a two-dimensional slab geometry. Magnetic islands are evolved to finite amplitude with a nonzero resistivity. The resistivity and flows are then set to zero and the system is allowed to relax toward equilibrium. A y-type singular current layer in the equilibrium state is identified fo...
