abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
the significance of the study of deixis was then mentioned. the purpose of the present study from the outset was to provide a comprehensive overview of all kinds of deixis in persian, describing and defining each in true while considering them structurally and semantically. chapter two consisted of two main parts. a review of the english studies in this respect, besides presenting persian liter...
هدف: این مطالعه به مقایسه میزان اثربخشی دو روش متداول درمان بیماری all دوران کودکی در مرکز طبی کودکان انجام شده است. روش مطالعه: این مطالعه به صورت یک بررسی مشاهده ای (observational) از نوع طولی (longitudinal) و به صورت کوهورت گذشته نگر (historical cohort) انجام شده است. حجم نمونه مورد بررسی شامل 246 کودکی بود که طی سالهای 1370 تا 1386 در مرکز طبی کودکان با تشخیص all بستری شده و تحت درمان قرار...
: لوکمی شایع ترین بدخیمی در کوکان است. لوکمی لنفوبلاستیک حاد 25% بدخیمی های کودکان وتقریبا 75% لوکمی های کودکان را شامل می شود. مهمترین عامل تعیین پیش آگهی اتخاذ درمانی متناسب با ریسک می باشد که با توجه به ویژگی های بالینی مورفولوژیک، ایمونوفنوتیپ و سیتوژنتیک تعیین می گردد. هدف از این مطالعه تعیین ایمونوفنوتیپ و ترانسلوکاسیون کروموزومی بیماران کمتر از 15سال مبتلا به لوکمی بیمارستان امیرکبیر ارا...
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
Three hypotheses that could account for deficits in the retrieval of category information in Alzheimer's disease (AD) were evaluated: abnormal organization, class- or category-specific vulnerability, and limitation by general factors, such as decreased processing speed. Relative to 18 elderly control subjects, 18 patients with AD produced fewer items in a category fluency task and had longer re...
According to the "embodied cognition" theory and the "sensory-motor model of semantic knowledge": (a) concepts are represented in the brain in the same format in which they are constructed by the sensory-motor system and (b) various conceptual categories differ according to the weight of different kinds of information in their representation. In this study, we tried to check the second assumpti...
In [ l ] the Makhoul Conjecture Challenge was published. To answer was the question whether or not the location of the peak of a digital stable all-pass filter lies in [0, 2p-11, where p is the order of the all-pass filter. In this paper we construct numerous counter-examples, prove a new theorem stating that there is at least an upper bound on the order of p3’2 for the location of the peak, an...
