fixed myocardial defects in both stress and rest images, could be artifactual as a result of soft tissue attenuation. to increase specificity and identify the false positive results, we used gated technique to evaluate the wall motion and wall thickening as an index to differentiate real ischemic lesions from artifactual defects. 93 patients were studied. in 46 patients (48.8%) fixed perfusion ...

among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
in this thesis we will present three topics. we define approximate fixed points in fuzzy normed spaces. also we obtain some necessary and sufficient conditions on the existence of? -fixed points for ? > 0. at the continue some results about approximate fixed points for a class of non-expansive maps on g-metric spaces are obtained and we define approximate fixed points in partial metric spa...
Brlek et al. conjectured in 2008 that any fixed point of a primitive morphism with finite palindromic defect is either periodic or its palindromic defect is zero. Bucci and Vaslet disproved this conjecture in 2012 by a counterexample over ternary alphabet. We prove that the conjecture is valid on binary alphabet. We also describe a class of morphisms over multiliteral alphabet for which the con...
Soft-tissue attenuation artifacts generally appear as fixed perfusion-scan defects. Gated 99mTc-tetrofosmin SPECT may help differentiate myocardial infarction (MI) from artifacts, as fixed defects with decreased function (wall motion and thickening) probably represent MI, whereas attenuation artifacts represent preserved function. Methods: Ungated stress and gated rest 99mTc-tetrofosmin SPECT w...
UNLABELLED Soft-tissue attenuation artifacts generally appear as fixed perfusion-scan defects. Gated (99m)Tc-tetrofosmin SPECT may help differentiate myocardial infarction (MI) from artifacts, as fixed defects with decreased function (wall motion and thickening) probably represent MI, whereas attenuation artifacts represent preserved function. METHODS Ungated stress and gated rest (99m)Tc-tet...
conclusions excellent esthetic and functional results achieved; total treatment duration was about 72 months. case presentation this is a case report about the successful orthodontic treatment of a patient with mild hemifacial microsomia (hfm), using a non-surgical orthopedic and orthodontic treatment approach. the aim of this approach was to make the best noninvasive modality to treat hfm. a 7...
ترمیم asd primum درافراد با رنج سنی متفاوت معمولا در برگیرنده عوارض کوتاه مدت و تاخیری می باشد. مابصورت مطالعه توصیفی و گذشته نگر در صدد تعیین نتایج جراحی با تکنیک اصلاح شده در بیماران با نقص (partial a-v canal defect)sdprimum در مراکز جراحی قلب کرمانشاه از سال 1373 تا مهرماه 1380 می باشیم.
