Previous studies on HTS coils can be put into two categories: tape surface coils and thin-film surface coils[1-4]. In this study, we build a whole new Bi2Sr2Ca2Cu2O3 (Bi-2223) superconducting volume coil (length of 8 cm) designed for the mice whole body imaging at Bruker 3T MRI system. The HTS volume coil has 2.3 folds higher S/N than that of the HTS volume coil at 300K for the mice body screen...
the ability of composing a coherent and extended piece of writing in second language is considered as a fundamental factor to convey information and ideas of learners through the academic issues. although learners may achieve a perfect academic writing skill through assigning the l2 tasks in content based instruction, but demonstration of their abilities may be related to their ability in l1 es...
We describe the use of a transverse field RF surface coil that improves 1.5 T proton MR spectroscopy in the human calf. A 2-element figure-of-eight (FO8) transverse field RF surface coil (diameter 2R=10 cm; separation between the two linear current elements 2s=1cm) and a circular loop (CL) coil of equal diameter where built and tested with proton PRESS spectra at 1.5 T. The H PRESS spectra obta...
Transcranial magnetic stimulation (TMS) is a non-invasive neurom odulation technique used to treat various neurological disorders, including major depression. Since the cerebellum complex structure connected almost throughout central nervous system, TMS has gained popularity in field of cerebellar neurostimulation and promises stimulate activity non-invasively. The coil material play significan...
Transcranial magnetic stimulation (TMS) is a neuromodulation technique that noninvasively depolarizes neurons in the brain. During TMS, pulse (or multiple pulses) of time-varying field (H) delivered to brain using specialized coils. The quadruple butterfly coil (QBC) novel design shows increased focality induced electric over standard figure-of-eight (FoE) coil. Using 50 different head models c...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Previously we proposed an eccentric figure-eight coil that can cause threshold stimulation in the brain at lower driving currents. In this study, we performed numerical simulations and magnetic stimulations to healthy subjects for evaluating the advantages of the eccentric coil. The simulations were performed using a simplified spherical brain model and a realistic human brain model. We found t...
deposite the different criticisms on contrastive analysis it has been proved that the results of it(when processed)can be usuful in a tefl environment,specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims. the consonants,vowels,stress and intonation of the twolanguages are described by the same model-ta...
Intermittent theta burst stimulation (iTBS) over the dorsomedial prefrontal cortex (DMPFC) has shown promise in open-label trials of depression. In this randomized, double-blind, sham controlled trial we evaluate iTBS DMPFC for anhedonia, avolition, and blunted affect patients with schizophrenia or Active was delivered 1200 pulses per session, twice daily ten weekdays at target intensity an ang...
