Optical densities before bleaching and final Lin curves of planewave phase holograms recorded in Agfa—Gevaert 8E75HD emulsions were measured for various combinations of developers (AAC, Pyrogallol and Catechol) and bleaching agents (R-9 and EDTA). To characterize the processing, the square…

An analytical approximate technique for conservative nonlinear oscillators is proposed. This method is a modification of the generalized harmonic balance method in which analytical approximate solutions have rational form. This approach gives us not only a truly periodic solution but…

The bibliographic impact factor (BIF) of Thomson Scientific is sometimes not a valid scientometric indicator for a number of reasons. One major reason is the strong influence of the number of “source items” or “articles” for each journal that the…

Triathlon is considered an endurance sport composed by the individual disciplines of swimming, cycling and running which are generally completed in this sequential order. It has been suggested that triathlon performance can be predicted by maximal oxygen uptake (VO2max). However,…

Voltammetry and FTIR–ATR techniques have been employed to investigate polyphenol films formed on platinum surfaces by electrochemical oxidation of phenol. The media used in the electropolymerization were aqueous carbonate solutions, with and without Na2S. The polymeric films created are not…

This paper describes a multisensorial robotic system to automatically construct metallic structures. Two robots must work cooperatively in the same workspace to perform the task. The robots are automatically guided using visual and force sensor information. A new time-independent visual…

The successfulness of students at school is influenced by how the knowledge is attained. Family, media and the same age groups largely contribute to it. The recent Hungarian practice of home training is not so much attractive. A family is…

Although the anthropometric profiles of Olympic athletes, as a group, are well known, there is still a need for specific reference data for each sport given that each discipline has its own characteristics. This study has been designed considering the…

The way the coach act the most during the development of the game is meanwhile verbal behaviour directed to their players (Moreno et al., 2000), being it influenced by his own cognitions, motivations, and emotions, together with players behaviours and…

Very few studies exist on biomechanics of rhythmic gymnastic. Four leaps of an experienced high
level (national competition) rhythmic gymnast athlete (16yo, 175 cm height, 50 kg weight) were analyzed
in order to provide firsts descriptive data of these movements,…
