The aims of this study were to analyze the relationship between maximum isometric strength levels in different upper and lower limb joints and serve velocity in competitive tennis players as well as to develop a prediction model based on this information. Twelve male competitive tennis players (mean ± SD; age: 17.2 ± 1.0 years; body height: 180.1 ± 6.2 cm; body mass: 71.9 ± 5.6 kg) were tested ...

Digital templating with external calibration markers is the standard method for planning total hip arthroplasty. We determined the geometrical basis of the magnification effect, compared magnification with external and internal calibration markers, and examined the influence on magnification of the position of the calibration markers, patient weight, and body mass index (BMI). A formula was der...

OBJECTIVE To examine psychometric properties of the Self-Care Inventory-revised (SCI-R), a self-report measure of perceived adherence to diabetes self-care recommendations, among adults with diabetes. RESEARCH DESIGN AND METHODS We used three data sets of adult type 1 and type 2 diabetic patients to examine psychometric properties of the SCI-R. Principal component and factor analyses examined...

Implicitly or explicitly, much innovation policy treats investments in research and development (R&D) as the main input to innovation. A large body of literature studies has challenged this, highlighting role external sources based on learning by doing, using interacting (DUI). Nonetheless, there been limited empirical how firm-internal activities promote DUI affect innovation, important such a...

We have used combinations of subcellular fractionation, specific cytochemical tracers, and quantitative immunoadsorption to determine when, where, and in which intracellular structure internalized asialoglycoproteins (ASGPs) are segregated from their receptor. All membrane vesicles containing the receptor (R+ vesicles) were quantitatively immunoadsorbed from crude microsomes with Staphylococcus...

OBJECTIVE To conduct the first meta-analysis evaluating the internal and external validity of the sluggish cognitive tempo (SCT) construct as related to or distinct from attention-deficit/hyperactivity disorder (ADHD) and as associated with functional impairment and neuropsychological functioning. METHOD Electronic databases were searched through September 2015 for studies examining the facto...

The problem of indexing multidimensional objects is considered. First, a classification of existing methods is given along with a discussion of the major issues involved in multidimensional data indexing. Second, a variation to Guttman’s R-trees (R+-trees) that avoids overlapping rectangles in intermediate nodes of the tree is introduced. Algorithms for searching, updating, initial packing and ...
