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. In this paper we will study the influence of the…

Fixation-free rehalogenating bleaching is an interesting for the production of phase holograms. The shrinkage of the emulsion is reduced in comparison with other bleaching methods (reversal bleaching or rehalogenating bleaching with fixation). In this paper we present experimental results for…

Industrial wastewater with a high value of CDO (Chemical Demand of Oxygen e. g. - 100 000 mg.l-1) was treated by electrolysis. The pH, temperature and anode material of the electrolysis process have been optimized. It was shown that the…

Photopolymers are studied as holographic recording materials for recording computer-generated phase holograms. The recording was performed using a holographic copying process, in which the master is produced by means of a high resolution graphic device. To our knowledge it is…

Bleaching is one of the most widely used techniques in the production of phase holograms of high quality on photographic emulsion, particularly in rehalogenating techniques without a fixation step. These techniques were very well understood when Agfa 8E75 HD emulsion…

As a way of forecasting future evolution of inequalities in disease burden and mortality, trends in preventive health behaviours by social class were examined. Using the Spanish National Hearth Survey from 1987 to 1997 the evolution of the Health Practices…

Se identifican en fracciones de membranas plasmáticas aisladas de células ascíticas AS-30D de hepatocarcinoma de rata, tres glicoproteínas de 125 kDa, 115 kDa y 105 kDa (gp125, gp115 y gp105) que son adenililadas utilizando ATP como sustrato. Esta adenililación es…

This paper analyzes the efforts made by the Telefonica Group (the main Spanish firm in the telecommunications sector) to evolve from a bureaucratic culture to another oriented towards total quality and the customer. The need for this change came as…

The purpose of this pilot study was to develop and examine the psychometric properties of the Diabetic Care Teacher Support Questionnaire, a 31-item self-report instrument to assess diabetic children’s perceptions of the diabetes specific support received from their teachers at…

The aim of this pilot study was to develop and assess the preliminary psychometric properties of the Health Professional Support Questionnaire for diabetic children, an instrument to assess the perceived support from the health professional (doctor or nurse) attending children.…
