Gravity-induced sagging can amplify variations in goniometric measurements of the contact angles of sessile drops on super-liquid-repellent surfaces. The very large value of the effective contact angle leads to increased optical noise in the drop profile near the solid-liquid free surface and the progressive failure of simple geometric approximations. We demonstrate a systematic approach to det...

This paper deals with light sources in computer graphics. Different kinds of light sources and different types of solutions generally used are first described. Then, a new solution for directionally dependent light sources based on Noé and Péroche’s model[NP00] is proposed to avoid drawbacks of bilinear interpolation. The use of singular integrals with locally supported functions allows a fast ...

Introduction: Clinical evidence suggests that hamstring tightness influences lumbar pelvic rhythm and shortened increase the risk of injury to spine. Objectives: To determine association with tilt in standing position, trunk, range motion during forward bending among sewing machine operators Methods: A descriptive cross-sectional study was conducted 169 aged 18-55 years using passive knee exten...

INTRODUCTION One of the most important hand functions is thumb opposition, which results from flexion, abduction and axial rotation at the carpometacarpal, metacarpophalangeal and interphalangeal joints [1]. The thenar muscles, innervated by the median nerve, are critical for coordinated thumb movements. It is commonly observed that thumb opposition is impaired with median neuropathy [2]. The c...

The polarity of polyurethane coats was studied on the basis of the goniometric method for determination of wetting angle values, on the basis of calculated surface free energy (SFE) values by the van Oss-Good and Owens-Wendt methods, and on the basis of polarity measurements with the use of the (1)H NMR spectra. Test polyurethanes were synthesised in the reaction of methylene diphenyl 4,4'-diis...

The purpose of the study was to evaluate the influence of Fluori-Methane spray as a method of affecting passive range of motion measured at the right hip joint. Subjects were 30 normal volunteers randomly divided into an experimental group and a control group. A special table was constructed to position and stabilize each subject for monitoring the right lower extremity's resistance to side-lyi...

OBJECTIVE This study is designed to further characterize Limited Joint Mobility (LJM) of the hand using quantitative goniometric measurements among Black Africans with Type 2 diabetes mellitus and non-diabetes. METHODS Seventy-six patients with Type 2 diabetes and 63 normal controls matched for age and gender were purposively selected. Visual clinical examination and quantitative goniometric ...
