Assembly of Lipopolysaccharide in Escherichia coli Requires the Essential LapB Heat Shock Protein
PublicationHere, we describe two new heat shock proteins involved in the assembly of LPS in Escherichia coli, LapA and LapB (lipopolysaccharide assembly protein A and B). lapB mutants were identified based on an increased envelope stress response. Envelope stress responsive pathways control key steps in LPS biogenesis and respond to defects in the LPS assembly. Accordingly, the LPS content in ΔlapB or Δ(lapA lapB) mutants was elevated, with...

Generalized regression neural network and fitness dependent optimization: Application to energy harvesting of centralized TEG systems
PublicationThe thermoelectric generator (TEG) system has attracted extensive attention because of its applications in centralized solar heat utilization and recoverable heat energy. The operating efficiency of the TEG system is highly affected by operating conditions. In a series-parallel structure, due to diverse temperature differences, the TEG modules show non-linear performance. Due to the non-uniform temperature distribution (NUTD) condition,...

Sensitive Demonstration of the Twin-Core Couplers including Kerr Law Non-Linearity via Beta Derivative Evolution
PublicationTo obtain new solitary wave solutions for non-linear directional couplers using optical meta-materials, a new extended direct algebraic technique (EDAT) is used. This model investigates solitary wave propagation inside a fiber. As a result, twin couplers are the subject of this study. Kerr law is the sort of non-linearity addressed there. Because it offers solutions to problems with large tails or infinite fluctuations, the resulting...

Instrument detection and pose estimation with rigid part mixtures model in video-assisted surgeries
PublicationLocalizing instrument parts in video-assisted surgeries is an attractive and open computer vision problem. A working algorithm would immediately find applications in computer-aided interventions in the operating theater. Knowing the location of tool parts could help virtually augment visual faculty of surgeons, assess skills of novice surgeons, and increase autonomy of surgical robots. A surgical tool varies in appearance due to...

Investigation of praseodymium and samarium co-doped ceria as an anode catalyst for DIR-SOFC fueled by biogas
PublicationThe Pr and Sm co-doped ceria (with up to 20 mol.% of dopants) compounds were examined as catalytic layers on the surface of SOFC anode directly fed by biogas to increase a lifetime and the efficiency of commercially available DIR-SOFC without the usage of an external reformer. The XRD, SEM and EDX methods were used to investigate the structural properties and the composition of fabricated materials. Furthermore, the electrical...

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...

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,...

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...

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...

Experimental study of the variations of the freezing points of ionic liquids in water
PublicationTemperatura zamarzania czystych soli alkiloimidazoliowych zawiera się w przedziale od - 70ºC do - 90ºC zależnie od długości podstawinika alkilowego oraz od rodzaju anionu. Celem niniejszej pracy jest znalezienie odpowiedniej metody pomiaru zmian temperatury zamarzania chlorku 1-metylo-3-oktyloimidazolu w wodzie. Wynik przeprowadzonych badań pozwolił na sporządzenie fragmentu diagramu fazowego dla wodnego roztworu chlorku...

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....

Chapter 21. Investigation on sorption of 1-methyl-3-octylimidazolium chloride on sewage sludge in wastewater treatment
PublicationNiniejsza publikacja stanowi opis zjawiska sorpcji chlorku 1-metylo-3-oktylo imidazolu w wysuszonym osadzie czynnym pochodzącym z oczyszczalni ścieków. Uzyskana w toku badań izoterma sorpcji potwierdza wielowarstwową adsorpcję długołańcuchowych cieczy jonowych. Stosunkowo wysoki współczynnik podziału KD wynika z pH w jakim prowadzony był eksperyment oraz wysokiej zawartości węgla organicznego w sorbencie (50,49%) i potwierdza,...
