A highly effective photochemical system for complex treatment of heavily contaminated wastewaters.

Significant efforts have been committed to the research and development of many advanced oxidation processes, including photocatalytic oxidations with titanium dioxide or the hydrogen peroxide and ferrous/ferric ion (H2O2/Fe2+(Fe3+)/UV (photo-assisted Fenton) process. This study reports the development of a novel photochemical system for complex treatment of heavily contaminated wastewaters based on the use of UV-C light and H2O2. Special attention was focused on the technology employed, including the reactor design, process controls, and performance optimization.

Prepulse inhibition of the acoustic startle reflex and oculomotor control.

Prepulse inhibition and the suppression of reflexive saccades on the antisaccade task are thought to tap inhibitory function. Reports of a lack of association between these measures suggest that they reflect different facets of inhibition. This study aimed to reexamine this relationship in a large sample and investigate the association of prepulse inhibition with oculomotor tasks that require inhibition of a reflexive saccade with lower concurrent processing demands than antisaccades, namely the oculomotor delayed response and fixation with distractors tasks.

[New recommendations for nutritional requirements for the Czechoslovak population].

The authors present new recommended energy and nutrient allowances for the population of CSFR. The allowances are defined for 29 physiological groups, incl. 11 groups of children and adolescents and 18 groups of adults (productive age and more advanced age groups).

[Trends in lipid consumption in the Czechoslovak population].

The health status of our population is not satisfactory, an important part in this respect is played among others also by nutrition. The authors submit information on changes in the energy, protein and fat consumption of the Czechoslovak population during the period between 1936 and 1987. The increase in fat consumption is due in the first place to the increased consumption of meat, milk, eggs and fats.
