this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
In this paper we present a new class of operators based on Trapezoid Fuzzy numbers such as Trapezoid Fuzzy Prioritized Weighted Mean (TFPWM) operator, Trapezoid Fuzzy Prioritized Weighted Geometric Average (TFPWG), Trapezoid Fuzzy Prioritized Weighted Harmonic Average(TFPWH) operators to solve multiple attribute group decision making (MAGDM) problems. Unlike other (MAGDM) techniques here the at...
background: ototoxic chemicals can impair the sense of hearing and balance. in the past decades, the ototoxicity of solvents and their interaction with noise have become evident. this study has been carried out in the shoe manufacturing factory in tehran (iran) with the aim of evaluating the combined effects of noise and toluene on the workers' hearing. materials and methods: this cross-se...
the present study is an attempt to investigate the potential impact of inspirational quotes on improving english abstract vocabulary recall. to achieve this goal, a multiple choice language proficiency test of 60 items including vocabulary and grammar component was administered to a sample of 63 second-semester male and female students whose age ranged between 17 to 22 and they were studying en...
In this paper, we study the two weight commutators theorem of Riesz potential on an arbitrary homogeneous group H dimension N. Moreover, in accordance with results Euclidean space, acquire quantitative weighted bound group.
BACKGROUND Triolein emulsion infusion into the brain produces transiently increased vascular permeability. OBJECTIVES The purpose of this study was to find the minimum percentage of triolein emulsion required for studying vascular permeability with minimal brain edema. MATERIALS AND METHODS Sixty healthy cats were divided into six groups according to the concentration of emulsified triolein...
We compared the short-term magnetic resonance imaging (MRI) evolution of new multiple sclerosis (MS) lesions enhancing after single dose (SD) (0.1 mmol/kg) or triple dose (TD) (0.3 mmol/kg) gadolinium-DTPA (Gd) to explore possible differences in the pathological substrates of acute MS lesions. Brain MRI scans were obtained at baseline and every 4 weeks for a 3-month period in 18 relapsing-remit...
introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
In this paper, we characterize the bonudedness and compactness of weighted composition operators from weighted Bergman spaces to weighted Bloch spaces. Also, we investigate weighted composition operators on weighted Bergman spaces and extend the obtained results in the unit ball of $mathbb{C}^n$.
BACKGROUND AND PURPOSE It has previously been demonstrated that comparison of signal intensity (SI) between selected brain structures on T1-weighted images enables distinction between the absence or presence of hypoxic-ischemic (HI) brain injury in young infants. The aim of the present study was to assess whether this method of brain structure T1-weighted SI comparison also enables prediction o...
