Removal of cyclohexane vapors from air in biotrickling filters: Effects of gas mixture composition and circular economy approach
PublicationThis work presents results of investigations on biotrickling filtration of air polluted with cyclohexane co-treated in binary, ternary and quaternary volatile organic compounds (VOCs) mixtures, including vapors of hexane, toluene and ethanol. The removal of cyclohexane from a gas mixture depends on the physicochemical properties of the co-treated VOCs and the lower the hydrophobicity of the VOC, the higher the removal efficiency...

The comparison of cytotoxic and genotoxic activities of glucosinolates, isothiocyanates, and indoles
PublicationChemopreventive properties of Brassica vegetables are attributed mainly to their characteristic compounds—glucosinolates (GLs) and their main hydrolysis products—isothiocyanates (ITCs) and indoles. In this study, we compared antiproliferative activity (MTT test in HT29 cells) and genotoxic effects (comet assay in HT29 cells and restriction analysis in a cell-free system) of three GLs (sinigrin (SIN), glucotropaeolin (GTL), and...

Fast Collaborative Graph Exploration
PublicationWe study the following scenario of online graph exploration. A team of k agents is initially located at a distinguished vertex r of an undirected graph. At every time step, each agent can traverse an edge of the graph. All vertices have unique identifiers, and upon entering a vertex, an agent obtains the list of identifiers of all its neighbors. We ask how many time steps are required to complete exploration, i.e., to make sure...

ECT image analysis methods for shear zone measurements during silo discharging process
PublicationW pracy przedstawiono wyniki pomiarów zmian koncentracji piasku bezkohezyjnego zachodzących w cylindrycznym modelu silosu opróżnianym grawitacyjnie, w którym występowały silne efekty dynamiczne. Pomiary wykonano z zastosowaniem tomografii pojemnościowej. Badania przeprowadzono dla zróżnicowanego zagęszczenia początkowego piasku oraz różnego stopnia szorstkości ścian. Szczegółowej analizie poddano zmianę koncentracji materiału sypkiego...

The influence of selenium addition during seeds' germination on the biological properties of obtained sprouts
PublicationSelenium plays a vital role in human body, because in the form of aminoacids (Se-methionine, Se-cysteine) it is found in the active centres of over 25 enzymes, including those regarded as 'cytoprotective'. Unfortunatelly, its daily intake in Poland and other European countries is lower than predicted by dietary recommendations. The consequences of selenium deficiency in diet might be severe, including higher susceptibility to cardio-vascular...

Curing characteristics, mechanical and thermal properties of reclaimed ground tire rubber cured with various vulcanizing systems
PublicationGround tire rubber was thermo-mechanical reclaimed at 120 °C using a co-rotating twin screw extruder. The effect of vulcanizing system type on curing characteristics, static mechanical properties (tensile strength, elongation-at-break, hardness and resilience), dynamic mechanical properties and thermal properties of reclaimed ground tire rubber was investigated. Reclaimed rubber was cured using different types of vulcanization...

Plasma-Based Deposition and Processing Techniques for Optical Fiber Sensing
PublicationPlasma-based techniques are widely applied for well-controlled deposition, etching or surface functionalization of a number of materials. It is difficult to imagine fabrication of novel microelectronic and optoelectronic devices without using plasma-enhanced deposition of thin films, their selective etching or functionalization of their surfaces for subsequent selective binding of chemical or biological molecules. Depending on...

Na skrzyżowaniu, czy na rondzie
PublicationOd pewnego czasu obserwuję polaryzację poglądów na temat roli uniwersytetu. Jest ona widoczna zarówno w środowisku akademickim, jak i w jego otoczeniu. Oto kilka przykładów: Wyznawcy krajowych ram kwalifikacji (krk) okopali się na swoich stanowiskach i nie przyjmują do wiadomości opinii znaczącej części środowiska akademickiego, która widzi w krk wyłącznie biurokratyczne uciążliwości. Na szczęście ci pierwsi dostrzegli już pewne...

Studies on removal of Zn(II), Cd(II) and Pb(II) ions in polymer inclusion membrane transport with calix[4]-crown-6 derivatives
PublicationZbadano selektywność procesu wydzielania jonów cynku(II), kadmu(II) i ołowiu(II) z wodnych roztworów azotanowych zawierających równomolową mieszaninę tych trzech metali (cMe= 0,01 M) w procesie transportu przez polimerowe membrany inkluzyjne (PIM) przy użyciu w roli przenośników jonów pochodnych kaliks[4]-korony-6. Membrany typu PIM syntezowano z trójoctanu celulozy (nośnik), eteru o?nitrofenylopentylowego (pastyfikator) i pochodnych...

Process Control of Biogas Purification Using Electronic Nose
PublicationNowadays, biogas produced from landfills and wastewater treatment plants or lignocellulosic biomass is important sustainable and affordable source of energy. Impurities from biogas stream can cause a serious odor problem, especially for residents of areas immediately adjacent to production plants. Therefore, biogas pre-treatment is necessary to protect engines that convert biogas into energy and in order to increase the specific...
