The Gdańsk University of Technology is a technical university in Gdańsk-Wrzeszcz, and one of the oldest universities in Poland. It has nine faculties and with 41 fields of study and more than 26 thousand undergraduate, as well as about 400 doctoral students. It currently employs 2500 people, including 1200 academic teachers. The rector of the university is professor Henryk Krawczyk.Some degree courses and various specialisations are taught in English. Moreover, some of the courses offered by GUT are unique in Poland, for instance ones in Construction Chemistry, Nanotechnology, Geodesy and Cartography, as well as Engineering of Natural Resources. Students have access to specialist laboratories, lecture theatres with multimedia facilities, a library with 1.2 million volumes and various sports facilities. Undergraduates can also join one or more of 60 student science or language societies as well as other organisations. During the recent years, Gdańsk University of Technology has made many changes, both preserving the tradition of a technical university and being open for economic and social demands. University is now facing transformation: from a digital university into a SMART university, realizing new international projects and innovative incentives. Great emphasis is placed on maintaining high education quality standards – GUT is the second Polish institution of higher education to hold the prestigious ECTS Label. GUT is also the first and only Polish university to be a member of the CDIO Initiative, founded by the Massachusetts Institute of Technology in collaboration with Chalmers University of Technology in Sweden. CDIO aims to provide an education for engineers that enables them to “Conceive, Design, Implement and Operate” pro-industrial technological systems.Active member of a number of university networks and associations, e.g. Baltic Science Research , Baltic University Network and the Baltic Sea Region University Network.

Toxoplasma gondii is a parasitic protozoan which is the cause of toxoplasmosis. Although human toxoplasmosis in healthy adults is usually asymptomatic, serious disease can occur in the case of congenital infections and immunocompromised individuals. Furthermore, despite the exact recognition of its etiology, it still presents a diagnostic problem. Diagnosis of toxoplasmosis is mainly based on the results of serological tests detecting anti-T. gondii-specific antibodies in the patient's serum sample. The specificities and sensitivities of serology tests depend mostly on the diagnostic antigen(s) used. Most of the commercial serological kits currently available are based on Toxoplasma lysate antigens (TLAs). In recent years, many studies showed that recombinant antigenic proteins of T. gondii may be an alternative source of antigens which are very useful for the serodiagnosis of toxoplasmosis. This article presents a review of current studies on the application and usefulness of different T. gondii recombinant antigens in serological tests for the diagnosis of human toxoplasmosis.

Physical Review A - Atomic, Molecular, and Optical Physics | Year: 2016

We consider a Dirac one-electron atom placed in a weak, static, uniform magnetic field. We show that, to the first order in the strength B of the external field, the only electric multipole moments, which are induced by the perturbation in the atom, are those of an even order. Using the Sturmian expansion of the generalized Dirac-Coulomb Green function [R. Szmytkowski, J. Phys. B 30, 825 (1997)JPAPEH0953-407510.1088/0953-4075/30/4/007; J. Phys. B 30, 2747 (1997)JPAPEH0953-407510.1088/0953-4075/30/11/023], We derive a closed-form expression for the electric quadrupole moment induced in the atom in an arbitrary discrete energy eigenstate. The result, which has the form of a double finite sum involving the generalized hypergeometric functions 3F2 of the unit argument, agrees with the earlier relativistic formula for that quantity, obtained by us for the ground state of the atom. © 2016 American Physical Society.

Earthquake Engineering and Structural Dynamics | Year: 2010

The phenomenon of earthquake-induced structural pounding has attracted the researchers' attention for several years now. The aim of this paper is to show the results of two experiments concerning interactions between elements made of different building materials, such as steel, concrete, timber and ceramic. The first experiment was conducted by dropping balls from different height levels onto a rigid surface, whereas the second one was focused on pounding-involved response of two tower models excited on a shaking table. The results of the impact experiment show that the value of the coefficient of restitution depends substantially on the prior-impact velocity as well as on the material used. Based on these results, the appropriate formulations have been suggested to be applied in the numerical simulations. The results of the shaking table tests show a considerable influence of the material used for colliding elements on the behaviour of structures during earthquakes.

This paper reports an evaluation of the accuracy of the discrete Green's function (DGF) formulation of the finite-difference time-domain (FDTD) method. Recently, the closed-form expression for the DGF and its efficient numerical implementation were presented, which facilitates applications of the DGF in FDTD simulations of radiation and scattering problems. So far, the accuracy of the DGF formulation of the FDTD method has been rather marginally treated in the literature. Moreover, although windowing has been reported as an efficient method of DGF waveform truncation and a remedy for stability issues, the accuracy and usability of this technique have not yet been fully evaluated. In this paper, previously unrevealed accuracy limitations of the DGF formulation of the FDTD method are demonstrated in several numerical tests. Specifically, the truncation errors are compared for the most frequently applied windowing functions, with the best performance shown for the Hann's window. © 2012 IEEE. Source

The problem of cancellation of strong, potentially nonstationary, echoes in noise radars and passive radars utilizing digital transmissions is considered. The proposed solution is a multi-stage procedure. Initial clutter estimates, obtained using the least mean squares (LMS) algorithm, are refined using specially designed filters, matched to spectral densities of targets and clutter. When the postprocessing filters are noncausal, the performance of the proposed canceler is improved compared to the solution based on causal filters. © 1991-2012 IEEE. Source
