Introduction:MAMMI is a dedicated PET based on high resolution detectors placed close to the breast. In this study, we presented a GATE model for the simulation of MAMMI scanner and model its performance of the MAMMI based on an adaptation of the NU 4-2008 NEMA standard.  Methods:A detailed of geometry MAMMI system that uses scintillation crystals coupled...

“The urban researches in Iran aren't applicable to the real challenges of Iran’s cities”. In order to examine the mentioned hypothesis, “existing problems of Iran’s cities” and “Iran’s urban researches” are compared by means of the urban news and research journals. The framework analyze method [a kind of qualitative research method] has been used to analyze the data in the form of axial-themati...

chordomas are low-grade malignant tumors of bone that occur almost exclusively in the axial  skeleton. chordomas are rare in children and adolescents and comprise

In order to achieve integrated condition in the girth welding of high pressure natural gas transmission pipelines, the weld zones and its surrounding area should have good mechanical properties. Residual stresses are an important defect especially in the girth welding of the pipeline. In this study, two API X70 steel pipes (with spiral seam weld) of 56 inches outside diameter and 0.780 inch wal...

BACKGROUND Smoking is one of the main environmental risk factors involved in several rheumatic diseases according to ACR 2014, it is included among the risk factors for severe axial spondyloarthritis. OBJECTIVES The objective is to study the association between smoking and the activity of the disease, the functional impact and the severity of the axial spondyloarthritis. METHODS It is a tra...

Jasmonates are oxygenated lipids (oxylipins) that control defense gene expression in response to cell damage in plants. How mobile are these potent mediators within tissues? Exploiting a series of 13-lipoxygenase (13-lox) mutants in Arabidopsis (Arabidopsis thaliana) that displays impaired jasmonic acid (JA) synthesis in specific cell types and using JA-inducible reporters, we mapped the extent...

in this paper, the modified euler-bernoulli beam model is presented to examine the influence of surface elasticity and residual surface tension on the critical force of axial buckling of nanotubes in the presence of rotary inertia. an explicit solution is derived for the buckling loads of microscaled euler beams considering surface effects. the size-dependent buckling behavior of the nanotube d...

The main purposes of the present work are devoted to the investigation of the free axial vibration, as well as the time-dependent and forced axial vibration of a SWCNT subjected to a moving load. The governing equation is derived through using Hamilton's principle. Eringen’s nonlocal elasticity theory has been utilized to analyze the nonlocal behaviors of SWCNT. A Galerkin method based on a clo...

total calcium with overt bone disease is hard to explain. The history of constipation, nocturia and polyuria, albeit mild, do suggest hypercalcaemia and it may be that the ionized calcium was elevated without the total calcium being raised. There are many points of similarity in the patient reported here with the case reported by Mather in 1953. His patient was a 39-year-old woman who had devel...
