- How people react to a fire alarm has been studied in retrospect as well as in experiments. In the present study, the choice of exit was examined with respect to the distance to exits and open or closed emergency exit. The second part deals with some communication aspects regarding identification of signs. It is shown that the subjects prefer a familiar ordinary cash exit even if the distance to that exit is longer than to the nearest emergency exit. However, if the emergency exit is open and the subjects can see the outside, an emergency exit becomes more attractive and most of the subjects choose the emergency exit. The understanding of signs important in a fire evacuation situation is very good. Copyright © 1999 John Wiley & Sons, Ltd.

- The influence of selected sulphonamides such as sulphacetamide (SCM) and ptoluenesulphonamide(p-TSA) on the Anammox process was investigated. The short-term (14-hour) and long-term (90-day) exposure of mixed Anammox culture to SCM and p-TSA wasapplied. The aim of long-term exposure study (conducted in continuous-flow bioreactors) was toinvestigate a long-term influence of sulphonamides on Anammox process and on adaptation ofAnammox culture to sulphonamides. The batch test performances resulted in the N-removal ratefor non-acclimated and acclimated Anammox culture. The experiments were carried out atsulphonamides concentration of: 10, 20, 40, 80, 100 and 1000 mg/dm3. The results confirmed thatboth sulphonamides inhibit the Anammox process, however, the effect is more evident in the caseof SCM. The higher the sulphonamides concentration, the stronger inhibition of microorganisms’activity was observed.
