in chapter one we will describe definitions and preliminary results to provide the global context of our own results to be presented in detail in the subsequent chapters in chapter two we consider degree-one maps of the circle and we study their rotation set. our main result in this chapter says that if the map is topologically mixing then its rotation interval is nontrivial (that is, not reduc...
the purpose of the present work is to establish a one-to-one correspondence between the family of interval type-2 fuzzy reflexive/tolerance approximation spaces and the family of interval type-2 fuzzy closure spaces.
in this paper, we introduce a satisfaction function (sf) to compare interval values on the basis oftseng and klein’s idea. the sf estimates the degree to which arithmetic comparisons between two intervalvalues are satisfied. then, we define two other functions called lower and upper sf based on the sf. weapply these functions in order to present a new interpretation of inequality constraints wi...
in this paper, we introduce the notion of $m$-fuzzifying interval spaces, and discuss the relationship between $m$-fuzzifying interval spaces and $m$-fuzzifying convex structures.it is proved that the category {bf mycsa2} can be embedded in the category {bf myis} as a reflective subcategory, where {bf mycsa2} and {bf myis} denote the category of $m$-fuzzifying convex structures of...
background: prolongation of qt interval is one of the most important abnormalities in cardiovascular system of cirrhotic patients. the aim of this survey was determination of propranolol effect on frequency adjusted qt interval (qtc). materials and methods: thirty six cirrhotic patients (m/f=20/16, mean age:56 â± 3.8 years) and 40 healthy age and sex matched controls (m/f=25/15, mean age: 58 â±...
ramadan fasting is one of the most important religious duties of muslims, that its effect on the heart has not been determined yet. our objective was to evaluate the effect of ramadan fasting on ventricular repolarization as assessed by qt interval, corrected qt interval, qt dispersion or corrected qt dispersion. sixthy healthy subjects aged 20 to 35 years were dispersion included in this study...
حوضه ی رسوبی کپه داغ در شمال و شمال شرقی ایران قرار گرفته و سازند خانگیران یکی از مهمترین سازندهای پالئوژن این حوضه میباشد. به منظور مطالعه این سازند ناودیس چهل کمان واقع در غرب شهر سرخس، شرق حوضه ی رسوبی کپه داغ انتخاب گردیده است. این سازند در برش مورد نظر دارای 136 متر ضخامت بوده و لیتولوژی آن شامل تناوبی از مارن به رنگ سبز زیتونی و مارن آهکی به رنگ زرد کرمی می باشد. مرز زیرین آن با سازند چهل...
