This paper describes the measurement techniques of emissions from UWB devices discussed in ITU-R task group (TG) 1/8 to study the compatibility between ultra-wideband (UWB) devices and radiocommunication services. This paper also provides the background idea behind the measurement methods, as the final output of the discussion, i.e. ITU-R Recommendation, will not contain any citations to the re...
We have grown TiO2 and AlN under ultra high vacuum and high pressure conditions and studied their structures with using AES and SEM techniques. The obtained results show that an amorphous film of TiO2 and AlN could be formed on silicon substrate. Furthermore, TiO2 and AlN are high – K dielectric materials and they can thus be replaced to ultra thin gate oxide film.
introduction: in the kindling-induced seizure model, low and repeated electrical or chemical stimulations, can elevate the neural network excitability and induce epileptiform seizures. opioid receptors are widely distributed in different areas of the brain. on the other hand, morphine has paradoxical effects and induces elevation or alleviation of the pain sensation and excitability, at differe...
زمینه و هدف: همگام با پیشرفت های علمی اخیر در زمینه درمان زخم، پانسمان های مدرن با بهره گیری از تکنولوژی و دانش روز طراحی و تولید شدند. چنین پانسمان هایی می توانند با حفظ و کنترل رطوبت زخم در کنار سایر شرایط، محیط مناسب ی را برای درمان مرطوب زخم فراهم نمایند. هدف از این مطالعه تعیین تاثیر دو روش پانسمان خشک و مرطوب بر بهبود زخمهای سوختگی بوده است. روش بررسی : این پژوهش نیمه تجربی و روش نمونه ...
introduction and objective: alport’s syndrome (hereditary nephritis with deafness) is a familial uncommon disease that ultra-structural studies are gold standard method of its diagnosis. materials and methods:we studied 26 iranian patients suspicious of alport’s syndrome by electron microscopy. we examined 19 men and 7 women (male to female ratio was 2.7) and the average age was 1.5 years (with...
