Application of Peracetic Acid for Biological Foam Elimination in the SBR Bioreactor
PublikacjaPrzedstawiono wyniki wstępnych badań nad zastosowaniem kwasu nadoctowego (PAA) do likwidacji piany biologicznej, spowodowanej przez bakterię nitkowatą Microthrix parvicella. Wykazano, że okresowe zraszanie powierzchni piany małymi dawkami kwasu nadoctowego (rzędu kilkudziesięciu ml 1% roztworu PAA/na 1 m2 piany o grubości 1 cm) powoduje niemal natychmiastwy zanik piany, wytworzonej na powierzchni osadu czynnego w bioreaktorze...

A Monte Carlo Strategy to simulate Positrons and Positronium in biological Materials
PublikacjaWe present an algorithm for Monte Carlo simulations of positron tracks in biological materials. The algorithm takes into account the cross-section data for elastic and inelastic collisions between positrons and molecules and processes like direct annihilation, ionization and positronium formation. In the case of positronium formation, the algorithm considers the interactions of positronium with molecules. The algorithm can be used...

Synthesis and biological activity of mycophenolic acid-amino acid derivatives
PublikacjaIn search of new immunosuppressants, mycophenolic acid (MPA) was coupled with amino acid methyl esters followed by hydrolysis to analogs bearing free carboxylic groups. The obtained compunds were tested in vitro as growth inhibitors of lymphoid cell line (Jurkat) and human peripheral blood mononuclear cells (PBMC) from healthy donors. According to obtained results recovering of free carboxylic group increased their activity. Additionally,...

Biological and mechanical research of titanium implants covered with bactericidal coating
PublikacjaThe paper concerns the biological and mechanical properties of titanium implants with an antibacterial coating. The Ti13Zr13Nb alloy samples were coated with hydroxyapatite (HAp) coatings using the electrophoretic deposition technique (EPD). Subsequently, the surface of the samples was modified with silver, copper, and nickel nanoparticles by the immersion method. Different titanium sample types (i.e. HAp-only and nanometals-enriched...

Design, synthesis, and biological evaluation of tetrahydroquinolinones and tetrahydroquinolines with anticancer activity
PublikacjaColorectal cancer (CRC) is the most commonly diagnosed cancer in Europe and the United States and the second leading cause of cancer related mortality. A therapeutic strategy used for the treatment of CRC involves targeting the intracellular levels of reactive oxygen species (ROS). In this study, we synthesized a series of novel tetrahydroquinolinones and assessed their ability to inhibit CRC growth and proliferation by evoking...

The Occurrence and Role of Tetrasphaera in Enhanced Biological Phosphorus Removal Systems
PublikacjaThe application of enhanced biological phosphorus removal (EBPR) in wastewater treatment plants (WWTPs) has commonly been utilized worldwide. However, the optimum efficiency has not been realized over the past decades, prompting many studies and publications. The limitations, especially comprehension of the abundance and actual potential of polyphosphate-accumulating organisms (PAOs), are not fully understood. Recently identified...

Real-Time Volatilomics: A Novel Approach for Analyzing Biological Samples
PublikacjaThe use of the ‘omics techniques in environmental research has become common-place. The most widely implemented of these include metabolomics, proteomics, genomics, and transcriptomics. In recent years, a similar approach has also been taken with the analysis of volatiles from biological samples, giving rise to the so-called ‘volatilomics’ in plant analysis. Developments in direct infusion mass spectrometry (DI-MS) techniques have...

Deregulation of the labour markets in the countries of Central and Eastern Europe — selected issues
PublikacjaThe countries of Central and Eastern Europe in the 1990s pursued the transformation processes which were to result in introducing systemic changes and building market economies. It was a process requiring adjustment of the regulatory and system framework to the requirements of the EU. One of the areas covered by the changes was the labour market. The reforms related to the functioning of national labour markets necessitated taking...

Global value chains and labour markets – simultaneous analysis of wages and employment
PublikacjaThis study examines the overall effect of global value chains (GVCs) on wages and labour demand. It exploits the World Input–Output Database to measure GVC involvement via recently developed participation indices (using both backward and forward linkages) and the relative GVC position using three-stage least squares regression. We find that the relative GVC position is negatively correlated with wages and employment and that the...
