Badania nieniszczące mostu jako podstawa do oceny jego stanu na potrzeby realizacji przejazdu ponadnormatywnego
PublicationZagadnieniami związanymi z analizą możliwości realizacji przejazdów ponadnormatywnych przez obiekty mostowe zajmują się zespoły inżynierskie i naukowe na całym świecie. Wiele z analiz udaje się wykonać przy użyciu standardowych i typowych metod. Jest jednak grupa obiektów, dla których wymagane jest podejście indywidualne. Dla nich dopiero zaprojektowanie i zrealizowanie indywidualnie dobranego planu badawczego jest jedyną możliwością...

Low temperature broad band dielectric spectroscopy of multiferroic Bi6Fe2Ti3O18 ceramics
PublicationIn the present research the tool of broadband dielectric spectroscopy was utilized to characterize dielectric behavior of Bi6Fe2Ti3O18 (BFTO) Aurivillius-type multiferroic ceramics. Dielectric response of BFTO ceramics was studied in the frequency domain (Δν=0.1Hz – 10MHz) within the temperature range ΔT=-100°C – 200°C. The Kramers-Kronig data validation test was employed to validate the impedance data measurements and it was found...

Identification and properties of the psychrophilic bacterium Desulfolatea psychrophila single-stranded DNA binding proteins
PublicationTo study the biochemical properties of SSB from Desulfolatea psychrophila (DpsSSB), we have cloned the ssb genes obtained by PCR and have developed Escherichia coli overexpression systems. The gene consists of an open reading frame of 426 nucleotides encoding SSB protein of 142 amino acids with a calculated molecular mass of 15.6 kDa and it is the smallest known bacterial SSB protein indentified to date. The amino-acid sequence...

Model tests of cast-in-place piles formed by using different types of auger
PublicationModel tests are still a popular research tool used to observe and determine the mechanisms of pile-soil interaction. Due to the significant scale effect, the results of model tests performed in the 1g system can only be analysed from the qualitative side. This article describes and presents the results of 1g pile model tests carried out for comparative purposes. There were tested the effectiveness and efficiency of various types...

High-performance graphene-based biosensor using a metasurface of asymmetric silicon disks
PublicationIn recent years, optical biosensors widely applicable for medical applications, have received much attention. In this paper, we propose a high-performance polarization-insensitive optical biosensor based on a graphene-dielectric metasurface. The metasurface consists of an asymmetric dielectric disk array that supports a high Q-factor Fano resonance. The provided sharp Fano resonance results in an enhanced light-matter interaction...

Multiple output CMOS current amplifier
PublicationIn this paper the multiple output current amplifier basic cell is proposed. The triple output current mirror and current follower circuit are described in detail. The cell consists of a split nMOS differential pair and accompanying biasing current sources. It is suitable for low voltage operation and exhibits highly linear DC response. Through cell devices scaling, not only unity, but also any current gains are achievable. As...

Reconfiguring Minimum Dominating Sets in Trees
PublicationWe provide tight bounds on the diameter of γ-graphs, which are reconfiguration graphs of the minimum dominating sets of a graph G. In particular, we prove that for any tree T of order n ≥ 3, the diameter of its γ-graph is at most n/2 in the single vertex replacement adjacency model, whereas in the slide adjacency model, it is at most 2(n − 1)/3. Our proof is constructive, leading to a simple linear-time algorithm for determining...

Performance Analysis of A Photovoltaic-Thermal Integrated System
PublicationW artykule przedstawiono analizę energetyczną i egzergetyczną układu zintegrowanego PV/T. Straty egzergii występują zawsze w układach, w których procesy zachodzą ze zmianą temperatury i są proporcjonalne do wzrostu entropii systemu. Analiza egzergetyczna pozwala zlokalizować miejsce, wielkość i źródło termodynamicznej nieefektywności i ta informacja, trudna do pozyskania w inny sposób (np. przez analizę energetyczną) jest przydatna...

METHOD OF ROUTING SHIPS SAILING IN DEDICATED ENVIRONMENT
PublicationThe method for determining the suboptimal route of sailing vessels operating in a restricted area of the sea are proposed in the paper. The dynamics of the environment including weather conditions and speed characteristics of ships sailing are considered. As optimiza-tion criterion, measure sailing time T, and the number of maneuvers performed ω, are taken into account. An heuristic algorithm, and the appropriate application routing...

Diagnostyka toksoplazmozy u kobiety ciężarnej, płodu i noworodka — stan obecny i nowe możliwości
PublicationW artykule opisano problem toksoplazmozy, skutki oraz obecną diagnostykę. Przedstawiono metody serologiczne pozwalające wykryć pierwotne zarażenie T. gondii u kobiet ciężarnych oraz szereg technik pośrednich i bezpośrednich wykorzystywanych w celu potwierdzenia bądź wykluczenia toksoplazmozy wrodzonej u noworodka. Ponadto wskazano potencjalne możliwości w diagnostyce toksoplazmozy, jakie niosą za sobą nowe techniki (np. 2D Western-blotting),...

High yield expression and single step purification of Toxoplasma gondii SAG1, GRA1, GRA7 antigens in Escherichia coli.
PublicationPraca przedstawia metodę uzyskiwania antygenów rekombinowanych Toxoplasmagondii o wysokiej czystości, które można zastosować w immunodiagnostyce. Antygeny T. gondii eksprymowane w komórkach E. coli zawierały polihistydynowedomeny fuzyjne na końcu N i C białka. Pozwalało to na jednoetapowe oczyszczanie białek metodą chromatografii metalopowinowactwa na złożu Ni2+ -IDA-Sepharose. Immunoreaktywność antygenów rekombinowanych...

Dissociation energies of protonated water clusters
PublicationRelative abundances of positively ionized water clusters formed in a low-pressure electrical discharge as function of reduced electric field were obtained by using drift cell and quadrupole mass spectrometer. It was noticed that some clusters say with n = 4 were more abundant than others, at comparable drift conditions. Dissociation energies have been derived from equilibrium conditions for relative clusters abundances. The Hartree-Fock...
