Application, design and operation of constructed wetland systems: case studies of systems in the Gdańsk region, Poland
PublikacjaDifferences in operation result from physical, chemical and biological conditions, which directly influence transformations in the whole aquatic-matrix-plants environment. Depending on the quantity of inflowing organic matter load and the rate of biochemical processes, the contaminations could be removed or/and retuned in the system. From this point of view the facility should be designed and operated in such way that the highest...

Stability studies of selected polycyclic aromatic hydrocarbons in different organic solvents and identification of their transformation products
PublikacjaGłównym problemem w laboratoriach analitycznych jest konserwacja próbek i ekstraktów przeznaczonych do analizy. Rozpatrując procesy degradacji z analitycznego punktu widzenia i związanej z tym wiarygodności uzyskiwanych wyników pod uwagę należy wziąć wpływ procesów degradacji w badanym elemencie środowiska na poziom stężenia składników śladowych; wpływ tych samych procesów na poziom składników śladowych w już pobranych próbkach...

Spectroscopic studies of Nb-doped tricalcium phosphate glass-ceramics prepared by sol-gel method
PublikacjaCalcium-phosphate based glasses and glass-ceramics play a crucial role in the tissue engineering development. Apart from their high biocompatibility and excellent ability to undergo varying degrees of resorbability1, they exhibit relatively high bioactivity and due to that they are commonly used as bone and dental implants. A substantial research effort is devoted to improve calcium-phosphate materials physico-chemical properties...

Evidence of the impact of sport policies on physical activity and sport participation: a systematic mixed studies review
PublikacjaParticipation in sport contributes to increased physical activity (PA) levels. Increasing PA is a public health concern due to its recognised impact on health outcomes. International policy actors such as the Council of Europe, the World Health Organisation (WHO) and the International Society for Physical Activity and Health (ISPAH) have recommended that ‘sport for all’ is promoted both for public health and as a basic right. This...

Studies on treatment of bitumen effluents by means of Advanced Oxidation Processes (AOPs) in basic pH conditions
PublikacjaThe paper presents the results of studies on chemical treatment of effluents from production of bitumen of petroleum origin. Due to the presence of sulfide ions, the pH of these effluents is strongly alkaline. Several Advanced Oxidation Processes (AOPs) were studied, including the use of hydroxyl and sulfate radicals oxidants, the hydrodynamic cavitation as well as sonocavitation. The best processes allow to obtain 45% reduction...

Numerical Studies on Propellers in Open Water and behind Hulls aiming to support the Evaluation of Propulsion Tests
PublikacjaA RANS based numerical analysis of propellers can contribute considerably to our understanding of propeller/hull interaction. It may also allow for a review of scaling procedures on results from experimental fluid dynamics (EFD). Using various RANS codes (Fluent, CFX, STAR-CCM+ and FreSCo+) on common test cases the authors first focused on propeller open water (POW) calculations. Next we simulated the propeller hull interaction...
