In this context, the question of discipline in the classroom and classroom management have become extremely topical. The question of discipline/indiscipline and mainly the negative behaviour of pupils in the classroom have become, besides other issues like the teachers' social status or financial rewards for their work, one of the severe issues which teachers have to deal with in many countries. The second part of our research project VEGA No. 1/0223/16 was focused on implementing the programme selection process for managing classroom discipline suitable for our country. This article deals about preventive programs as a way to optimise classroom discipline

Modified Photobioreactor for Biofixation of Carbon Dioxide by Chlorella vulgaris at Different Light Intensities

The performance of a modified bioreactor inside a light enclosure for carbon dioxide biofixation by Chlorella vulgaris was investigated. The influence of different light intensities on the CO2 biofixation and biomass production rates was evaluated. The results showed that the photon flux available to the microalgal cultures can be a key issue in optimizing the microalgae photobioreactor performance, particularly at high cell concentrations. Although the optimal pH values for C. vulgaris are in the range of 6–8, cell growth can take place even at pH 4 and 10. Batch microalgae cultivation in the photobioreactor was used to investigate the effect of different light intensities. The maximum biomass concentration of 1.83 g L−1 was obtained at a light intensity of 100 μmol m−2s−1 and under aeration with 2 L min−1 of 2 % CO2-enriched air
