Bleached holograms are one of the most interesting techniques used to produce phase holograms of high quality on photographic emulsions. Of particular interest is the method of fixation-free rehalogenating bleaching. Using Kogelnik's coupled-wave theory we shall obtain information about the…

The redox process undergone by the electrochemically synthesized poly(2,2-dithiodianiline), poly(DTDA), has been examined in
acetonitrile-water mixtures by electrochemical and spectroscopic techniques. The spectroscopic properties of this material are equivalent to those exhibited by the chemically synthesized one. The polymeric structure…

This paper presents a multiagent recommendation system (RecMAS) able to coordinate the interactions between a user agent (AgUser) and a set of commercial agents (AgComs). It provides a useful service for monitoring changes in the AgUser’s beliefs and decisions based…

To validate clinically an algorithm for correcting the error in the keratometric
estimation of corneal power by using a variable keratometric index of refraction (nk) in a normal healthy population.

Since the changing of the political and economic system in 1989-1990 in Hungary, volunteer movements have appeared all over the country. Volunteers of different ages and socioeconomic backgrounds are engaged in a wide range of activities, wishing to add values…

The aim of this study was to analyse the evolution of critical velocity and critical
stroke rate during 12 weeks of training in age group swimmers. Fourteen age group
male swimmers took part in this investigation. The evaluation took place…

Performing Arts Medicine is a broad field that includes the study of medical conditions and injuries incurred by dancers, instrument musicians and vocalists. Musicians' playing-related health problems have focused more and more the interest of scientists, researchers, physicians, physiotherapists and,…

The role of the nebulizer on the sodium chloride interferent effects in ICP-AES was investigated. Three different pneumatic nebulizers coupled to a cyclonic spray chamber were investigated: a V-groove (VGN) and two new pneumatic concentric nebulizers specifically designed to work…

The aim of the present study was to analyze the relationship among general throwing tests, with a medicine ball, and throwing velocity tests with and without opposition in different groups of handball players, thus analyzing the influence of technique and…

Phase equilibrium data regression is an unavoidable task necessary to obtain the appropriate values for any model to be used in separation equipment design for chemical process simulation and optimization. The accuracy of this process depends on different factors such…
