PURPOSE To report the distribution of iris conicity (steepness of the iris cone), investigate associated factors, and test whether pseudophakia allows the iris to sink back. METHODS A population-based cross-sectional study was carried out. Ophthalmological examination including objective refraction, biometry, noncontact tonometry, and Scheimpflug imaging (Pentacam®, Oculus) was performed incl...

INTRODUCTION Obesity has been considered a chronic subclinical inflammation. High sensitivity C-reactive protein (hs-CRP) and fibrinogen are increasingly associated with cardiovascular risk. OBJECTIVES To evaluate the ability of anthropometric and body composition indicators in discriminating higher levels of hs-CRP and fibrinogen. METHODS 130 men (20-59 years) were assessed, having measure...

There has been a lot of research on ellipse fitting and measuring ellipticity of a set of points. However, when the shape is primarily hyperbolic or parabolic, there are no existing methods to measure such properties. This paper describes the first known methods of measuring conicity, hyperbolicity and parabolicity of a set of points. After finding the best conic fit, we measure the correspondi...

Background: Obesity is a coronary risk factor associated to myocardial infarction although waist to-hip-ratio has shown higher predictive power. Objective: The aim of this study was a Receiver Operating Characteristic anthropometric analysis in infarcted males to identify the strength of association for simple measurements, obesity and indicators such as, waist to-hip-ratios, waist to-height-r...

Conicity is an important characteristic that helps the railway vehicle to steer itself down track. However during operation, conicity tends change inconsistently due frictional contact at wheel-rail interface. Safety, reliability and ride comfort which are utmost importance for journey adversely affected changes in level beyond certain limit. Several techniques have been employed monitoring hea...

Gallium nitride (GaN) wires are used to build up capacitive flexible piezoelectric sensors dedicated to structural health monitoring applications. These slightly cone-shaped nanowires with a hexagonal cross section are grown on sapphire substrate by Metal Organic Vapor Phase Epitaxy (MOVPE); their length (L) can vary from few microns up to hundreds of microns, while the conicity angle (alpha) e...
