Środki masowego przekazu w życiu polonijnym
PublikacjaW kształtowaniu tożsamości współczesnej emigracji polskiej ważne miejsce odgrywają środki masowego przekazu. Powstają one zarówno w kraju wychodźstwa, jak i generowane są przez czynniki emigracyjne. Media polonijne pełnią istotną rolę w kształtowaniu tożsamości współczesnej emigracji polskiej. Powszechny jest pogląd, że stan mediów, w tym zwłaszcza prasy polonijnej odzwierciedla kondycję intelektualną i ekonomiczną emigracji polskiej....

Diving boldly into COVID‐19 contaminated wastewater: Eyes at nanotechnology‐assisted solutions
PublikacjaSeveral studies have been directed to find scalable, swift, accurate, and cost-effective strategies for detecting, monitoring, and treating coronavirus disease 2019 (COVID-19). Indeed, the lack of a fast and practical method for detecting the infected regions makes decision-making challenging to combat the critical pandemic-struck situations. The probable ‘wrong’, or rather inadequate, decisions not only have a boomerang effect...

Applications of Tensor Analysis in Continuum Mechanics
PublikacjaA tensor field is a tensor-valued function of position in space. The use of tensor fields allows us to present physical laws in a clear, compact form. A byproduct is a set of simple and clear rules for the representation of vector differential operators such as gradient, divergence, and Laplacian in curvilinear coordinate systems. The tensorial nature of a quantity permits us to formulate transformation rules for its components...

Znaczenie Internetu w rozwoju mass mediów mniejszości polskiej w krajach nadbałtyckich
PublikacjaWpływ Internetu na szeroko pojęty rozwój mass mediów mniejszości polskiej należy uznać za ograniczony i przejawiający się zróżnicowanym tempem oraz zakresem w odniesieniu do poszczególnych mediów i republik. Tylko na Litwie wszystkie, główne mass media zostały wprowadzone do Internetu, a na Łotwie jedynie audycja radiowa. Internet stanowi platformę dla przekazów tradycyjnych i jego pojawienie się nie doprowadziło do powstania mediów...

Spectral measurement of birefringence using particle swarm optimization analysis
PublikacjaThe measurement of birefringence is useful for the examination of both technical and biological objects. One of the main problems is that the polarization state of light in birefringent media changes periodically. Without the knowledge of the period number, the birefringence of a given medium cannot be determined reliably. We propose to analyse the spectrum of light in order to determine the birefringence. We use a Particle Swarm...

Application of the Fractional Fourier Transform for dispersion compensation in signals from a fiber-based Fabry-Perot interferometer
PublikacjaOptical methods of measurement do not require contact of a probe and the object under study, and thus have found use in a broad range of applications such as nondestructive testing (NDT), where noninvasive measurement is crucial. Measuring the refractive index of a material can give a valuable insight into its composition. Low‑coherence radiation sources enable measurement of the sample’s properties across a wide spectrum, while...

Modelling of elastic wave propagation in a bolted joint using a thin layer of shell elements
PublikacjaThere are many mathematical models describing the propagation of elastic waves through the imperfect boundary of two media. They were successfully applied to modelling of high frequency bulk waves and their interaction with local defects. On the other hand, the existing literature models of bolted connections ignore the aspect of imperfect connection between elements. Therefore, this paper presents the concept of application of...

Synthesis and biological evaluation of novel analogues of batracylin with synthetic amino acids and adenosine: an unexpected effect on centromere segregation in tumor cells through a dual inhibition of topoisomerase IIa and Aurora B
PublikacjaIn the search for new anticancer agents we designed and synthesized batracylin derivatives with linking synthetic amino acid side chains of different lengths and adenosine. Unexpectedly, we have found that in water and the culture media adenosine–amino acid–BAT conjugates form supramolecular structures and this prevents these compounds from entering cells. Consequently, these compounds exerted no biological activity when tested...
