Microbiological and biological aspects of wastewater tretment plant Wschód in Gdańsk Operation.
PublikacjaW pracy wykazano, iż w oczyszczalni Wschód w Gdańsku, pracującej w zmodyfikowanym systemie UCT, zanieczyszczenia bakteriologiczne ze ścieków są usuwane w granicach od 92% do ponad 99%, a zanieczyszczenia parazytologiczne niemal całkowicie. Pomimo tego odpływy są nadal dość znacznie zanieczyszczone bakteriologicznie o czym świadczy liczba bakterii wskaźnikowych oraz okresowa obecność bakterii z rodzaju Salmonella. Ustalono, iż...

The impact of sediment, fresh and marine water on the concentration of chemical elements in water of the ice-covered lagoon
PublikacjaThe common use of chemical elements by man has been contributing to their extraction for centuries. As a consequence, they have been directly or indirectly introduced into the biogeochemical cycle. In the framework of many conventions, mining and processing of elements are currently subject to many restrictions. However, their large load that has already been deposited in the soil and bottom sediments can be remobilised and...

Professional activity, gender and disease-related emotions: The impact on parents' experiences in caring for children with phenylketonuria
PublikacjaIntroduction: Clinical management of rare diseases often fails to acknowledge the challenges faced by caregivers.Whilst management of phenylketonuria (PKU) may not be considered as dire as other conditions, most studiesprimarily concentrate on clinical issues, dietary adherence, or the quality of life of the PKU patients, leavingcaregivers in the background. The aim of the study was to evaluate the psychosocial...

Impact of Low Switching-to-Fundamental Frequency Ratio on Predictive Current Control of PMSM: A simulation study
PublikacjaPredictive current control algorithms for permanent magnet synchronous (PMSM) drives rely on an assumption that within short intervals motor currents can be approximated with linear functions. This approximation may result either from discretizing the motor model or from simplifications applied to the continuous-time model. As the linear current approximation has been recognized as inaccurate in case when the drive operates with...
