mobile luminal mass of aortic arch is an unusual finding in patients with peripheral embolization. to search the source of these emboli, aortic arch mass should be considered. to our knowledge, transesophageal echocardiography (tee) can be a useful modality to demonstrate the nature and exact location of the mass. this report is illustrative of a large mobile aortic arch mass, histologically th...

paragangliomas are tumors that originate from extra-adrenal medullary neural crest derivatives. they are rarely located in retroperitoneal space. these tumors are often discovered incidentally during imaging studies performed for other reasons.periampullary cancers include adenocarcinomas arising from the pancreas, ampulla of vater, duodenum or distal common bile duct. the exact site of origin ...

in this work we consider conjugacy of elements and parabolic subgroups‎ ‎in details‎, ‎in a new class of artin groups‎, ‎introduced in an earlier work‎, ‎which may contain arbitrary parabolic subgroups‎. ‎in particular‎, ‎we find‎ ‎algorithmically minimal representatives of elements in a conjugacy class‎ ‎and also an algorithm to pass from one minimal representative to the others‎.

One of the risks distinguishes urban projects from other projects is to purchase of property obstacles. The matter is of more significance in large projects. Issues with regard to possessing property obstacles, lack of accurate layout drawings for underground facilities and following probable changes in designs make it vital to have specific studies on risk management of such projects. So thi...
