this study was performed from february to april 2006; several visits were made to abattoirs in the north of iran for hypoderma spp infestation. necropsy inspection of slaughtered and skinned animals were carried out by examination of the inner skin surface and subcutaneous tissues. warbles were isolated by squeezing nodules from subcutaneous tissues. in the case of abscess presence, aseptic sam...

endoscopic retrograde cholangiopancreatography (ercp) is widely used for the diagnosis and treatment of biliary and pancreatic tract disease. perforation is a rare complication of it, but it is associated with high rate of mortality, an overall mortality rate of 1.0-1.5%. here, a case of massive subcutaneous emphysema following ercp was reported without an obvious retroperitoneal or peritoneal ...

The MAX IV 3 GeV storage ring, currently under construction, pursues the goal of low electron beam emittance by using a multi-bend achromat magnet lattice, which is realised by having several consecutive magnet elements precision-machined out of a common solid iron block, 2.3-3.4 m long. With this magnet design solution, instead of having 1320 individual magnets, the MAX IV 3 GeV storage ring i...

INTRODUCTION We aimed to show the spread of local anesthetic following an ultrasound-guided, double-injection technique of a carotid sheath block before carotid endarterectomy. METHODS The study included 15 patients scheduled for elective carotid endarterectomy. The carotid sheath block was performed after ultrasound-guided localization of the carotid bifurcation (level C4-C6) at the posterio...

The uniform verification problem for parameterized systems is to determine whether a temporal property is true for every instance of the system which is composed of an arbitrary number of homogeneous processes. We consider some aspects of the inductionbased technique which assumes the construction of finite invariants of such systems. An invariant process is one which is greater (with respect t...

One of the most common forms of chronic pain is back pain. Until now, nothing has been known about the influence of visualizing one's own back on pain perception at this site. We tested 18 patients with chronic back pain and 18 healthy controls, by implementing online video feedback of the back during painful pressure and subcutaneous electrical stimuli over the trapezius muscle. Pain threshold...

in this paper we define a new type of rings ”almost powerhermitian rings” (a generalization of almost hermitian rings) and establish several sufficient conditions over a ring r such that, every regular matrix admits a diagonal power-reduction.
