Programming Geometry as a Creative Play with Architectural Form
PublicationIn the twenty-first century "programming" is the key word that opens unprecedented opportunities for design and materialization of geometrically complex architectural objects. From the digital designer perspective programming geometry can be seen as a creative play with a form and a process of generation/exploration as well as the possibility of applying the computing power as a co-designer in the process of finding solutions for...

In vitro biodegradation of bacterial nanocellulose under conditions simulating human plasma in the presence of selected pathogenic microorganisms
PublicationThe Biodegradability of bacterial nanocellulose (BNC) was assessed based on a change in its properties under conditions simulating human plasma in the presence or absence of the pathogens Staphylococcus aureus, Candida albicans and Aspergillus fumigatus. It was shown that the dry mass of BNC did not change during 6 months of incubation, except for samples stored in the presence of moulds, where the dry mass reduced by 40 %. The...

The Effect of Sodium Tetrafluoroborate on the Properties of Conversion Coatings Formed on the AZ91D Magnesium Alloy by Plasma Electrolytic Oxidation
PublicationMagnesium and its alloys are widely used in many areas because of their light weight, excellent dimensional stability, and high strength-to-weight ratio. However, the material exhibits poor wear and corrosion resistance, which limits its use. Plasma electrolytic oxidation (PEO) is an effective surface modification method for producing ceramic oxide layers on Mg and their alloys. The influence of the additions of sodium tetrafluoroborate...

Trailing-Edge Separation Control of a NACA 0015 Airfoil Using Dielectric-Barrier-Discharge Plasma Actuators
PublicationThis paper presents a part of the works conducted in the Plasmaero European project (task 3.1), where the trailing-edge flow separation of a NACA 0015 airfoil has been controlled using four different dielectric barrier discharge (DBD) actuator types at three institutions across Europe. The results show that it is possible to enhance the aerodynamic performance of aircraft at speeds up to 40 m/s. Dielectric-barrier-discharge vortex...

Structural changes of bacterial cellulose due to incubation in conditions simulating human plasma in the presence of selected pathogens
PublicationBacterial nanocellulose (BNC) is a natural biomaterial with a wide range of medical applications. However, it cannot be used as a biological implant of the circulatory system without checking whether it is biodegradable under human plasma conditions. This work aimed to investigate the BNC biodegradation by selected pathogens under conditions simulating human plasma. The BNC was incubated in simulated biological fluids with or...

The Effect of Posaconazole, Itraconazole and Voriconazole in the Culture Medium on Aspergillus fumigatus Triazole Resistance
PublicationTriazoles are the only compounds used as antibiotics in both medicine and agriculture. The presence of triazoles in the environment can contribute to the acquisition of azole resistance among isolates of Aspergillus fumigatus. The objective of this study was to investigate the effect of A. fumigatus exposure to triazoles on susceptibility to these compounds. Seventeen triazole-resistant and 21 triazole-sensitive A. fumigatus isolates...

Charakterystyka oporności Klebsiella pneumoniae New Delhi na karbapenemy
PublicationBakterie Klebsiella pneumoniae New Delhi, posiadające gen oporności na karbapenemy (blaNDM) zostały po raz pierwszy wyizolowane w 2008 roku w Szwecji od pacjenta wcześniej hospitalizowanego w Indiach. Bakterie te szybko rozprzestrzeniają się po całym świecie, a od 2011 roku występują również w Polsce. Stanowią one wysokie ryzyko epidemiologiczne, ponieważ gen oporności na karbapenemy przekazywany jest pomiędzy bakteriami poprzez...

Różnicowanie C. albicans i C. dubliniensis w oparciu o polimorfizm genu syntazy homocytrynianowej z wykorzystaniem metody PCR RFLP
PublicationNajczęstszym czynnikiem etiologicznym zakażeń wywołanych przez drożdżaki z rodzaju Candida jest C. albicans. Gatunek ten posiada bardzo zbliżone cechy fenotypowe do C. dubliniensis co często wiąże się z błędną identyfikacją. Skutkuje to wtórnym zakażeniem wywołanym przez współwystepujący gatunek C. dubliniensis, który nabywa oporność na flikonazol stosowany w terapii C. albicans. Celem badań była konstrukcja układu diagnostycznego...

On the Nonlinea Distortions of Sound and its Coupling with Other Modes in a Gasesous Plasma with Finite Electric Conductivity in a Magnetic Field
PublicationNonlinear phenomena of the planar and quasi-planar magnetoacoustic waves are considered. We focus on deriving of equations which govern nonlinear excitation of the non-wave motions by the intense sound in initially static gaseous plasma. The plasma is treated as an ideal gas with finite electrical conductivity permeated by a magnetic field orthogonal to the trajectories of gas particles. This introduces dispersion of a flow. Magnetoacoustic...
