Background: The present study assesses the frequency of injury in Europe’s top-level judokas, during competitions, and defines risk factors. Methods: members EJU Medical Commission collected data over period 2005 to 2020 using Injury Registration Form at top judoka tournaments. Results: Over 15 years study, 128 competitions with 28,297 competitors were included; 699 injuries registered. Of all ...
Abstract. Given a doubling measure μ on R, it is a classical result of harmonic analysis that Calderón-Zygmund operators which are bounded in L(μ) are also of weak type (1, 1). Recently it has been shown that the same result holds if one substitutes the doubling condition on μ by a mild growth condition on μ. In this paper another proof of this result is given. The proof is very close in spirit...
A change in subtask order in the psychological refractory period (PRP) paradigm increases the effect of stimulus onset asynchrony (SOA) on the second response. We used a paradigm with cued, randomly determined subtask order to test the hypothesis that this SOA by order switch overadditivity reflects order control, via "copying" stimulus order. In Experiments 1a and 1b, overadditivity was eviden...
this paper is analysing the role of economic reforms on the labour market in iranian industry in economic reform period (1990-2005), and in turn, it is comparing it with closed economic period (1979-1989). in order to do the above comparative analysis, the manufacturing industry has been categorized based on hecksher-ohlin and gause methodology. accordingly, we have some industrial groups, incl...
The present study examines a long-term statistical trend analysis of Total Ozone Content (TOC) data from the AURA satellite for latitudes 60° and S. A methodology eliminating strong dependence on season has been applied by introducing relative deviation average monthly TOC climatological average. presents comparisons trends zonal values its values. In addition, standard error both parameters is...
Although dual-task interference is ubiquitous in a variety of task domains, stop-signal studies suggest that response inhibition is not subject to such interference. Nevertheless, no study has directly examined stop-signal performance in a dual-task setting. In two experiments, stop-signal performance was examined in a psychological refractory period task, in which subjects inhibited one respon...
The standard bottleneck model of the psychological refractory period (PRP) assumes that the selection of the second response is postponed until the first response has been selected. Accordingly, dual-task interference is attributed to a single central-processing bottleneck involving decision and response selection, but not the execution of the response itself. In order to critically examine the...
We generalize the classical Cayley-Dickson doubling process starting with a quaternion algebra over a field F by allowing the scalar in the doubling to be an invertible element in the algebra. We investigate the resulting eight-dimensional algebras over F and show that they are division algebras for all scalars chosen in D outside of the base field F , if D is a division algebra.
