OBJECTIVE To determine the prevalence of overweight and obesity among adolescents in five Arab countries, relative to age and sex. METHODS A multistage stratified random sampling technique was used to select the secondary school students from five Arab countries (Kuwait, Libya, Palestine, Syria and United Arab Emirates). The total sample was 3302 (1584 males, 1718 females). Weight and height ...

BACKGROUND It is assumed that doctor-patient relationship plays an effective role in patients' satisfaction, medication adherence, and health outcomes since exploring different aspects of this relationship, such as addressing medication adherence, has rarely been investigated. Therefore, the main aim of the present study was to assess the impact of patients' satisfaction derived from communicat...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...

A cross-sectional study design and multistage sampling procedures were employed to select households for this study. Administrative areas were randomly selected ...
Background: Athletes’ use of androgenic-anabolic steroids (AASs) is a significant health problem. This study aimed to determine factors associated with AAS in male bodybuilders by applying the theory planned behavior (TPB). Methods: Using multistage random sampling procedure, this descriptive-analytical cross-sectional was performed on 429 athletes participating gyms Qom, Iran, 2019. The data c...
This paper presents the performance of a classifier built using the stackingC algorithm in nine different data sets. Each data set is generated using a sampling technique applied on the original imbalanced data set. Five new sampling techniques are proposed in this paper (i.e., SMOTERandRep, Lax Random Oversampling, Lax Random Undersampling, Combined-Lax Random Oversampling Undersampling, and C...
Abstract We1 develop Conditional Random Sampling (CRS), a technique particularly suitable for sparse data. In large-scale applications, the data are often highly sparse. CRS combines sketching and sampling in that it converts sketches of the data into conditional random samples online in the estimation stage, with the sample size determined retrospectively. This paper focuses on approximating p...
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
