f-Cycles - a new approach to providing fast service recovery at low backup capacity overhead
PublikacjaW artykule zaproponowano klasowy algorytm doboru tras przeżywalnych, wykorzystujący autorską koncepcję f-Cykli ochronnych. Celem podejścia było zminimializowanie wartości czasu odtwarzania uszkodzonych strumieni ruchu. Cel ten został osiągnięty poprzez dostosowanie wielkości obszaru ochrony w zależności od klasy usług. Badania symulacyjne pokazały, że wykorzystując autorką koncepcję f-Cykli ochronnych, możliwe jest również jednoczesne...

PublikacjaInhibitory polimeryzacji mikrotubul wykazują preferencyjną toksyczność wobec komórek mitotycznych. W ramach tego projektu badaliśmy czy oporność komórek ludzkich białaczek na inhibitor mikrotubul, winkrystynę, prowadzi do zmian w regulacji progresji cyklu komórkowego. Nasze wyniki wskazują, że oporności na winkrystynę towarzyszą zmiany w długości fazy G2 i M w nieobecności i obecności inhibitora wrzeciona mitotycznego, nokodazolu....

Effectiveness of various types of coating materials applied in reinforced concrete exposed to freeze–thaw cycles and chlorides
PublikacjaThis study assesses the durability of coated and uncoated concrete surfaces protected with four different coating materials: water-soluble (BW), solvent-based (BR), mineral (MI), and epoxy (EP). The durability assessment includes evaluating the absorption rate of water, pull-off adhesion strength, and coating material thickness. Concrete samples were subjected to immersion in regular water and a 7% urea solution, followed by...

Spectral Analysis of Capital Markets
PublikacjaIn this paper the problem of cycles existence in capital markets is addressed. A spectral analysis algorithm, which reduces signal-to-noise ratio, is proposed to derive cycle periodograms for the yield function of DJIA, WIG~20, and NIKKEI 225 indices. Peaks of the the periodograms provide premises to postulate the existence of some possible cycles. The 3.5 year periodicity in all 3 indices, which can be related to Kitchin cycle...

Application of Bladder Acellular Matrix in Urinary Bladder Regeneration: The State of the Art and Future Directions
PublikacjaConstruction of the urinary bladder de novo using tissue engineering technologies is the “holy grail” of reconstructive urology. The search for the ideal biomaterial for urinary bladder reconstruction has been ongoing for decades. One of the most promising biomaterials for this purpose seems to be bladder acellular matrix (BAM). In this review we determine the most important factors, which may affect biological and physical properties...

A shear stress micromodel of urinary tract infection by the Escherichia coli producing Dr adhesin
PublikacjaIn this study, we established a dynamic micromodel of urinary tract infection to analyze the impact of UT-segment-specific urinary outflow on the persistence of E. coli colonization. We found that the adherence of Dr+ E. coli to bladder T24 transitional cells and type IV collagen is maximal at lowest shear stress and is reduced by any increase in flow velocity. The analyzed adherence was effective in the whole spectrum of physiological...

Nanoparticle Tracking Analysis of Urinary Extracellular Vesicle Proteins as a New Challenge in Laboratory Medicine
PublikacjaUrinary extracellular vesicle (uEV) proteins may be used as specific markers of kidney damage in various pathophysiological conditions. The nanoparticle-tracking analysis (NTA) appears to be the most useful method for the analysis of uEVs due to its ability to analyze particles below 300 nm. The NTA method has been used to measure the size and concentration of uEVs and also allows for a deeper analysis of uEVs based on their protein...
