Performance-based outcomes such as the T-Test, Edgren Side Step Test (ESST), and Illinois Agility Test (IAT) have been used to assess agility in athletes and nonathletes; however, the reliability and validity of these tests have not been established. The purpose of this study was to establish the reliability and convergent construct validity of the ESST, T-Test, and IAT in young, nondisabled, p...

OBJECTIVE This study evaluated the pelvic ring fractures and injuries in patients admitted to and treated at this ward between August, 2012 and January, 2014. METHODS 66 patients were submitted to treatment protocols according to their age, gender, skin color, injury mechanism, location of the trauma, classification of their injuries, emergency intervention, associated injuries, injured side ...

Using aggregate data from the General Social Survey (GSS), 1974-1996, Lynn (1998) claims that the Black-White intelligence difference in the United States has not been narrowing over time. We replicate Lynn's analysis and challenge his conclusion by identifying several methodological problems. By analyzing changes in Black-White differences in the GSS vocabulary test across survey years, rather...

Performance of the echo canceller can be conventionally measured by putting white Gaussian noise into the echo canceller system. However, white Gaussian noise is not adequate as the test signal, since the performance may depend on the characteristics of input test signal, and the characteristics of the white Gaussian noise differ from those of real spoken language. This paper describes characte...

Analysing hair cortisol concentrations (HCCs) is a minimally invasive way to retrospectively assess long-term stress, and its application in studies of animal welfare stress has attracted considerable interest. However, not only stress-related effects but also hair-specific characteristics external influences can affect HCCs interfere with the interpretation results. Thus, it was aim this study...

FSW material flow and phase transformation were studied at the interface of dissimilar welding of Al 6013 to Mg. Defect free butt weld was obtained when aluminum and magnesium test plates were placed in the advancing side and retreating side respectively, and the tool was placed 1 mm off the weld centerline into the aluminum side. In order to understand how the materials flow during FSW, steel ...
