On the Use of Selected 4th Generation Nuclear Reactors in Marine Power Plants
PublicationThis article provides a review of the possibility of using different types of reactors to power ships. The analyses were carried out for three different large vessels: a container ship, a liquid gas carrier and a bulk carrier. A novelty of this work is the analysis of the proposal to adapt marine power plants to ecological requirements in shipping by replacing the conventional propulsion system based on internal combustion engines...

Effect of Thermal Treatment and Erosion Aggressiveness on Resistance of S235JR Steel to Cavitation and Slurry
PublicationS235JR steel is used in many applications, but its resistance to the erosion processes has been poorly studied. To investigate this resistance, cavitation, and slurry erosion tests were conducted. These tests were carried out at different erosion intensities, i.e., different flow rates in the cavitation tunnel with a system of barricades and different rotational speeds in the slurry pot. The steel was tested as-received and after...

Minute and diverse in fossil sticky stuff: Tanytarsini (Diptera: Chironomidae) from early Eocene Indian Cambay amber
PublicationWe here present a pioneering systematic review of fossil dipterans of the tribe Tanytarsini (family Chironomidae) discovered in Indian amber from Cambay. The specimens examined belong to five species: Gujaratomyia miripes, Stempellina stebneri sp. nov., Stempellinella pollex sp. nov., Tanytarsus forfex sp. nov. and Tanytarsus ramus sp. nov., which are described. All species belong to the oldest known Tanytarsini and come from the...

Searching for Solvents with an Increased Carbon Dioxide Solubility Using Multivariate Statistics
PublicationIonic liquids (ILs) are used in various fields of chemistry. One of them is CO2 capture, a process that is quite well described. The solubility of CO2 in ILs can be used as a model to investigate gas absorption processes. The aim is to find the relationships between the solubility of CO2 and other variables—physicochemical properties and parameters related to greenness. In this study, 12 variables are used to describe a dataset...

Antimicrobial molecular nanocarrier–drug conjugates
PublicationMany antimicrobial drugs are poorly active against pathogenic microbes causing intracellular infections, such as Mycobacterium tuberculosis or Plasmodium falciparum. On the other hand, several known antimicrobial agents are not effective enough because of their limited cellular penetration. A common feature of both challenges is the inability of an active agent to cross the biological membrane(s). One of the possible approaches...

Coastal cliff erosion as a source of toxic, essential and nonessential metals in the marine environment
PublicationDue to the rising environmental awareness, emissions and releases of pollutants, including metals, have been considerably reduced in the last decades. Therefore, the remobiliza-tion of natural and anthropogenic contaminants is gaining importance in their biogeochemical cycle. In the marine coastal zone, this process occurs during the erosion of a shore, especially the most vulnerable cliffs. The research was conducted in the...

Sorption of ionic liquids
PublicationCiecze jonowe przyciągają rosnącą uwagę a zakres ich potencjalnych zastosowań nieustannie się rozszerza. Aby ciecze jonowe mogły spełniać nie tylko wymagania technologiczne ale również wymagania odnośnie ochrony środwiska, ich oddziaływanie z poszczególnymi jego elementami powinno zostać poznane. Niniejsza publikacja zawiera szerokie studium literaturowe dotyczące oddziaływań cieczy jonowych z glebą. Ponadto przedstawiono wyniki...

Comparison of the Effects of Conventional and Alternative External Carbon Sources for Enhancing of the Denitrification Process
PublicationFood industry effluents are considered a potential alternative for methanol when seeking external carbon sources to enhance denitrification in municipal wastewater treatment plants (WWTPs). The aim of this study was to determine the immediate effects of dosing different carbon sources on the denitrification capability of process biomass from the "Wschod" WWTP in Gdansk (northern Poland). Five carbon sources, including settled wastewater,...

Rapid test for ionic liquids toxicity evaluation
PublicationW literaturze przedmiotu dostępne są dane na temat toksyczności cieczy jonowych, szczególności tych mających zastosowanie przemysłowe, gdzie toksyczność wyrażana jest jako EC50 mierzone względem konkretnego organizmu np. Vibrio fischeri, Daphnia magna itp. Z uwagi na taksonomiczne zróżnicowanie osadu czynnego nie jest możliwe bezpośrednie wnioskowanie na temat toksyczności cieczy jonowych w stosunku do osadu czynnego na podstawie...

Ionic liquids - greener solvents or environmental threat?
PublicationZe względu na niemierzalnie niską prężność par ciecze jonowe były uważane za 'zielone rozpuszczalniki'. Ich zastosowanie w technologiach (bio)chemicznych przynosi korzyści nie tylko ekologiczne ale również ekonomiczne. Niemniej jednak zanieczyszczenie środowiska poprzez przedostanie się cieczy jonowych do gleb i wód gruntowych wraz ze ściekami/odciekami przemysłowymi lub w wyniku przypadkowych rozlewów stanowi realne zagrożenie....
