Thermal ALD deposited Al2O3 films on silicon show marked difference in surface passivation quality as a function of annealing time (using rapid thermal process). An effective and quality passivation is realized in short anneal duration (~100s) which is reflected in the low surface recombination velocity (SRV <10 cm/s). The deduced values are close to the best reported SRV obtained by high therm...

Myocardial Perfusion Imaging (MPI) is a non-invasive modality with proven diagnostic and prognostic utility in coronary artery disease. We present case of Transthyretin Amyloid Cardiomyopathy (ATTR-CM) where MPI findings were vastly different from Transthoracic Echocardiogram (TTE) Cardiac Magnetic Resonance (CMR). A 78-year-old gentleman presented atypical chest pain to rule out ischemic heart...

Background: Previous studies have shown that morphine consumption during pregnancy may delay embryo development or cause abnormal nervous system function .The most attention of research focuses on the embryo, whereas it was not attended to the placenta as an important organ which is affected by opioides. The present study focused on the effect of maternal morphine consumption on development of ...

To explore the possibility of using graphene based biosensor, adsorption of hydrogen peroxide on graphene has been investigated using density functional theory. The electronic properties of defect free and defective graphene in the presence of different number of hydrogen peroxide have been studied. The graphene with the most stable configuration defect named as SW defect is considered. The hig...

bifid cardiac apex is a rare anomaly of human hearts. we report of the case of a 34-year-old man with a previous history of ventricular septal defect (vsd) and subvalvular pulmonary stenosis. he had undergone pulmonary commissurotomy and vsd closure 22 years before he was referred to our center for evaluation of progressive dyspnea. transthoracic echocardiography revealed atrial septal defect (...

although carbon nanotubes (cnt) have been employed as reinforcements in nanocomposites, presence of nano scale defects such as stone-wales and vacancy defects in carbon nanotubes (cnt) weakens the mechanical properties of these materials. in this paper the effects of defects in cnts on nanocomposite elastic behavior are investigated using molecular dynamics. stiffness matrices of cnt and nanoco...

in this paper, we proposed a novel structure for designing all optical filter based on photonic crystal structure. in designing the proposed filter, we simply employed a point defect localized between input and output waveguides as wavelength selecting part of the filter. the initial form of this filter is capable of selecting optical waves at =1560 nm, the transmission efficiency of the filte...

conclusions along with the technological advancement, different materials are employed according to the size of the cranium defect and the age of the case. the application of split costa cranioplasty for the small cranium defects in the region of patient’s face is the method with the least possibility of complications, and its cosmetic and functional results are quite promising. introduction os...

we have performed density functional theory (dft) calculations to investigate the properties of defect in arepresentative armchair model of silicon nanotubes (sints). to this aim, the structures of pristine and defective(5,5) sints have been optimized and the properties such as bond lengths, total energies, binding energies,.formation energies, gap energies, and dipole moments have been evaluat...
