ovarian hemangiomas are benign and rare tumors of female genital tract with less than 60 reported cases in the literature. a 38- yr- old woman was admitted to be’sat hospital, tehran, iran in 2012, due to severe abdominal pain. ultrasound evaluation revealed a 6 cm left ovarian cystic mass and serum tumor markers were normal. then, left salpingo-oophorectomy was performed for the patient. micro...

The study of the stability of differential equations without its explicit solution is of particular importance. There are different definitions concerning the stability of the differential equations system, here we will use the definition of the concept of Lyapunov. In this paper, first we investigate stability analysis of distributed order fractional differential equations by using the asympto...

In this paper the substantiation of the method of full averaging for fuzzy differential inclusions is considered. These results generalize the results of [17, 20] for differential inclusions with Hukuhara derivative and of [18] for fuzzy differential equations.

background: nodular hidradenoma or clear cell hidradenoma is a rare adnexal tumor arising from the eccrine glands. case report: a 60-year old female presented to the surgical out-patient clinic with complaints of breast lump of one year duration. fine needle aspirate (fna) of the lump yielded fluidly aspirate mixed with hemorrhage. on giemsa-stained smears, a possibility of benign cystic lesion...

in this study, a generalization of the theory of involute-evolute curves is presented for ruledsurfaces based on line geometry. using lines instead of points, two ruled surfaces which are offset in the senseof involute-evolute are defined. moreover, the found results are clarified using computer-aided examples

in previous studies we first concentrated on utilizing crisp simulationto produce discrete event fuzzy systems simulations. then we extendedthis research to the simulation of continuous fuzzy systems models. in this paperwe continue our study of continuous fuzzy systems using crisp continuoussimulation. consider a crisp continuous system whose evolution depends ondifferential equations. such a ...

introduction: it has been suggested that calculation of differential renal function (drf) using 99mtc-dmsa may lead to overestimation of the function of an obstructed kidney. the aim of this study was to evaluate the effect of diuretic administration on the determination of drf using 99mtc-dmsa scintigraphy in patients with dilated pelvis. methods: thirty three patients, aged from 2 months to 6...
