The properties of thermal emission of hot bodies is a central topic in Modern Physics [1]. The dependence of the Planck’s law only on the body temperature T but not on its material properties make pirometry a universal pyrometric technique [2]. The blackbody emission consists of unpolarized, incoherent radiation for bodies whose size is larger than the typical thermal wavelength, λT = hc/kBT, w...

In the infrared spectrum, two contributions to shadows exist: one part is reflective shadows resulting from occlusion of instantly reflected infrared rays, and the other part is thermal (IR) shadows occurring through occlusion of irradiance in the past. The realization of thermal shadows requires a thermal balance calculation in four-dimensions (three-dimensional geometry in one-dimensional tim...

We have produced 5 x 5 pixel arrays of microcalorimeters using bulk micromachining. Analysis of our data provides the thermal conductivity parameters of SixNy I p m thick membranes at 100 mK. Moreover wefind that the thermal transport at 100 mK in Si beams, with dimensions 1.25 mm x 0.35” x 35pm (length x height x width) is dominated by ballistic phonons with a mean free path of 110 pn. These t...

Neuropathic pain involves injury or alteration of the normal sensory and modulatory nervous systems to produce a set of symptoms that are often difficult to treat. Previous study indicates that saffron has anti-inflammatory properties that may be mediate by neurotransmitter system. In this study we determine the role of cannabinoids receptors in peripheral and central effects of Crocin on behav...

AIMS The present report describes a novel coronary fractional flow reserve (FFR) system which allows FFR assessment using a rapid exchange microcatheter (RXi). METHODS AND RESULTS The RXi microcatheter is compatible with standard 0.014" coronary guidewires facilitating lesion negotiation and FFR assessment in a wide range of coronary anatomies. In case of serial lesions, a microcatheter would...

tumefactive fibroinflammatory lesions (tfls) are rare idiopathic benign fibrosclerosing lesions that clinically simulate a malignancy. tfls are seen more frequently in males between 10 and 74 years of age. the usual site of involvement is the head and neck region, but rarely the extremities may be involved. coexisting fibrosclerotic processes have been reported including retroperitoneal fibrosi...

statement of problem: failure of endodontic treatment is determined on the basis of radiographic findings and clinical signs and/ or symptoms of the treated teeth. purpose: the purpose of this study was to determine endodontic treatment failure in relation to various factors influencing it in teeth with periapical lesions (clinically and radiographically). materials and methods: teeth which had...

introduction: chronic sclerosing sialadenitis is a relatively uncommon disorder of the salivary gland. because of its clinical similarity to a salivary gland neoplasm, this condition has been known as kuttner tumor and is classified as a tumorlike lesion. case report: this is the first reported case of bilateral kuttner tumor of the submandibular glands in iran. it was initially diagnosed as a ...

Description : Myelopathy is the term designated to all chronic cord lesions regardless of their etiologic origins which may be vascular, inflammatory, nutritional deficiency, post-radiation etc ... but the term myelopathy is more restrictive and should be reserved for a chronic cord lesion resulting from the reduction in the dimensions of the cervical spinal canal of which the main etiology is ...
