Objective: The Objective of this study was to determine the intrarater reliability of chest expansion at three different anatomical landmarks using a cloth tape measure among healthy peoples. Materials and Methods: 120 healthy male and female volunteers were evaluated on two occasions in different days. The measures consisted of chest expansion measurement at axilla, fourth intercostals and xip...

Many studies that demonstrate an increase in airway smooth muscle in asthmatic patients rely on the assumption that bronchial internal perimeter (P(i)) or basement membrane perimeter (P(bm)) is a constant, i.e., not affected by fixation pressure or the degree of smooth muscle shortening. Because it is the basement membrane that has been purported to be the indistensible structure, this study ex...

or 4, must be added to the urinometer reading to bring it to the true specific gravity. The estimation of chlorides can be done volumetrically with standard silver nitrate solution and potassium chromate as indicator; this method is sufficiently accurate for the purpose. The standard silver nitrate solution is made by dissolving 29.235 grammes of pure and dry crystals of silver nitrate in a lit...

JavaScript has grown to be among the most popular programming languages. However, performing change impact analysis on JavaScript applications is challenging due to features such as the seamless interplay with the DOM, event-driven and dynamic function calls, and asynchronous client/server communication. We first perform an empirical study of change propagation, the results of which show that t...

This study aims to determine the prevalence of health personnel with normal weight central obesity and to investigate whether this group had higher cardiovascular disease (CVD) risk factors than those of the people with normal weight and without central obesity. A waist-to-height ratio was calculated as waist circumference (at umbilical level) in cm divided by height in cm. The central obesity ...

Additive isotonic regression attempts to determine the relationship between a multi-dimensional observation variable and a response, under the constraint that the estimate is the additive sum of univariate component effects that are monotonically increasing. In this article, we present a new method for such regression called LASSO Isotone (LISO). LISO adapts ideas from sparse linear modelling t...

An important part of statistical analysis, perhaps the most important part, is the identification and quantification of sources of variation. For example, in a t-test the variation between groups is compared with variation within the groups to see if the former can be explained by the latter alone. The main tool for measuring variation is the standard deviation (SD), although it is sometimes us...

Economists often study consumers’ aggregate behavior across markets choosing from a menu of differentiated products. In this analysis, local demographic characteristics can serve as controls for market-specific heterogeneity in product preferences. Given rich demographic data, implementing these models requires specifying which variables to include in the analysis, an ad hoc process typically g...

BACKGROUND The incidence of hypertension (HTN) has increased rapidly in the Sudan in the last few years. The aim of this study was to determine the prevalence of uncontrolled HTN and the risk factors associated with it in Sudanese adults. METHODS This study was cross sectional. Data were collected using structured questionnaires filled in during interviews with subjects visiting referral clin...
