the relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
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...
15 صفحه اولResonant Alfvén waves in coronal arcades driven by footpoint motions
X-ray spectroscopy performed from different astronomical spacecrafts has shown that the solar corona is structured by magnetic fields having the shape of loops and arcades. These structures are formed by stretching and reconnection of magnetic fields, and remain stable from days to weeks. Also, sporadic or periodic brightenings of such structures have been detected in UV and soft X-ray observat...
متن کاملassessing political stability and instability in central asia and caucasus; case study, azerbaijan and kyrgyzstan
منطقه ی آسیای مرکزی وقفقاز به عنوان منطقه ای تاریخی و به دلیل دارا بودن ذخایر عظیم هیدرو کربنی از اهمیت ویژه ای برخوردار است. کشورهای این منطقه از عوامل عمده ی بی ثباتی نظیر عوامل جغرافیایی، اقتصادی، امنیتی، اجتماعی و سیاسی رنج می برند. پس از فروپاشی اتحاد جماهیر شوروی کشورهای منطقه از نعمت استقلال ناخواسته ای برخوردار شدند که مشکلات فوق را برای آن ها چندین برابر می کرد. در این روند برخی از این...
15 صفحه اولWave heating of coronal arcades driven by toroidally polarised footpoint motions Stationary behaviour in dissipative MHD
Westudy the heating of 2-D coronal arcades by linear resonant Alfvén waves that are excited by photospheric footpoint motions of the magnetic field lines. The analysis is restricted to toroidally polarised footpoint motions so that Alfvén waves are excited directly. At the magnetic surfaces where Alfvén waves, travelling back and forth along the loop-like magnetic field lines, are in phase with...
متن کاملQuiet Sun coronal heating: statistical model
Recent observations of Krucker & Benz (1998) give strong support to Parker’s hypothesis (1988) that small scale dissipative events make the main contribution to quiet Sun coronal heating. They also showed that these small scale events are associated not only with the magnetic network, but also with the cell interiors (Benz & Krucker, 1998). Taking into account in addition the results of the ana...
