conclusions primary scec is a rare and highly aggressive tumor. however, prognosis is poor and long-term survival is exceptional. crt could be an appropriate alternative to operation. patients and methods this brief report was carried out by reviewing the medical records of 22 patients with newly histologically proven scec that were treated between 2000 and 2010 at 2 tertiary academic hospitals...

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.

voltage fluctuation is one of the important types of power quality aspects originated from heavy fluctuating loads. this phenomenon can influence the behavior of induction motors, produce excessive vibration and increase the ohmic losses. in this paper a simplified model to evaluate the electrical characteristics of three phase induction motors under voltage fluctuation conditions will be prese...

an explanatory survey was carried out in 2008 to investigate the relationship between entrepreneurial orientation (eo), environmental factors, human capital and organizational characteristics vs. entrepreneurial performance among entrepreneurial firms in iranian agricultural sector. data were obtained from a sample of 120 iranian agricultural establishments, using an interview-oriented question...

municipalities in developing countries spend the highest proportion of their annual budget on unsatisfactory solid waste management service. until recently, solid waste management services in ethiopia were mainly the responsibilities of municipalities, which culminated in inadequate service provision. thus, the integration of micro and small enterprises (mses) by the government has recently bei...

in this paper, a numerical solution procedure is presented for the forced vibration of a piezoelectric nanowire under thermo-electro-mechanical loads based on the nonlocal elasticity theory within the framework of timoshenko beam theory. using hamilton’s principle, the nonlocal governing differential equations are derived. the governing equations and the related boundary conditions are discreti...

desmoplastic small round cell tumor (dscrt) is a rare variant of sarcoma with a highly aggressive behavior. it usually affects abdominal cavity and has a male predominance. its correct diagnosis and treatment is sophisticated and requires an experienced multidisciplinary team. hereby we present a 25 yrold man from kerman province in 2013 with abdominal mass and ascites who underwent sonograghy ...

dear editor, abdominal aortic aneurysm is often asymptomatic, less recognized, and causes considerable mortality and morbidity, if missed. the incidence varies from country to country and the occurrence is influenced by modifiable (smoking, coronary heart disease, hypertension, dyslipidemia, and prolonged steroid therapy) and non-modifiable risk factors (increasing age, male gender, and positiv...
