STATEMENT OF THE PROBLEM The stability of orthodontic treatment depends on preserving the patient's pretreatment arch form and arch size during and after treatment. PURPOSE This investigation was aimed to study the size and shape of Iranian mandibular dental arch and evaluate the correlation of their average dental arch with commercially available preformed rectangular nickel-titanium arch wi...
we present an application of the dual gabor frames to image processing. our algorithm is based on finding some dual gabor frame generators which reconstructs accurately the elements of the underlying hilbert space. the advantages of these duals constructed by a polynomial of gabor frame generators are compared with their canonical dual.
we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
A Retroesophageal Right Subclavian Artery as the Last Branch of the Aortic Arch- In Vivo Case Report
Three major arteries normally originate from the aortic arch. Variations of the aortic arch branches are observed in some cases. Rare variation of the aortic arch branches is originated from the retroesophageal right subclavian (RRS) artery as the last branch of the aortic arch. Variation of artery is possibly associated with the variation of the recurrent laryngeal nerve. This research p...
Purpose: Several variations of aortic arch have been reported yet. In present study another variation of aortic arch was reported. Right subclavian artery arises from posterior surface of the distal end of the aortic arch. Case Report: we present a variation of an aorticarch in which right subclavian artery arisesfrom posterior surface of the distal end of the aortic arch and passing behind eso...
The relationship between corresponding upper buccal cusp distance (IBD) and Gothic arch width, inter - condylar width (ICW) and inter-upper canine distance (ICD) in an Iranian population Dr. H.

dental arch form is one of the most important characteristics of dentition. however, this dimension usually receives less attention in diagnosis or treatment planning and orthodontic patients are traditionally classified with regard to their sagittal characteristics. the objectives of this study were to investigate if a relationship exists between the dental arch width (transverse dimension) an...
introduction: the persian squirrel (sciurus anomalus) is the only member of the sciuridae family found in the middle east. some people maintain them as pets, thus their referrals to veterinary hospitals has been increased recently. several morphological studies have been carried out mainly on the arch of aorta and its branches in common rodents, small mammals, and domestic animals but there are...
We report a case of a 32-week-gestation male who presented initially with symptoms suggestive of an interrupted aortic arch. The absence of a VSD prompted further investigations, including a CT angiogram, which revealed that he had an extensive thrombus in his aorta. He underwent a successful aortic thrombectomy with arch repair on cardiopulmonary bypass support. In view of the extensive thromb...
