Opis:
The metal oxide layers were deposited onto the surface of NiTi shape memory alloy using sol-gel method. Single-, double- and triple-layers were obtained from a colloidal solution containing the precursor of zirconium tetrabutoxide and titanium tetrabutoxide, and annealed at 300°C for 1 h in argon. Phase composition was determined by grazing incidence X-ray diffraction. Surface roughness of the metal oxide layers were determined by atomic force microscopy. Surface morphology and thickness of the obtained layers were studied by scanning electron microscopy. It was found that all obtained layers revealed a composite structure, and were characterized by low surface roughness and thickness parameters. A homogeneous structure of the metal oxide layers deposited onto the surface of the medical NiTi alloy was ascertained only for double- and triple-layers.

Opis:
This article presents the research on corrosion resistance of Zn-Al-Mg coatings with varying aluminium and magnesium content. Aluminium and magnesium were added directly to the zinc bath at 10:1 rate. There was found more than sixfold increase in corrosion resistance of zinc coatings with aluminium content at the level of 4% of weight and magnesium content at the level of 0.4% of weight. In contrast to the amounts applied in the literature, such content of these alloy additives in the zinc bath limits to a significant extent the amount of intermetallic phases in zinc coatings obtained from such baths. This, in consequence, results in high resistance to corrosion with simultaneous retention of high plasticity of these coatings.

Opis:
In an emergency situation, imitation of strategies of neighbours can lead to an order-disorder phase transition, where spatial clusters of pedestrians adopt the same strategy. We assume that there are two strategies, cooperating and competitive, which correspond to a smaller or larger desired velocity. The results of our simulations within the Social Force Model indicate that the ordered phase can be detected as an increase of spatial order of positions of the pedestrians in the crowd.

Opis:
The article presents the results of air temperature measurements inside a basement, outside it and in the ground adjacent to the building. The results and their analysis reveal that indoor thermal conditions develop differently in rooms with earth-contact structures. Intermittent heating exerts an important influence on the shaping of temperature conditions in a basement and its vicinity.

Opis:
After developing a Resonance Chiral Lagrangian (R χ L) model to describe hadronic τ lepton decays, the model was confronted with experimental data. This was accomplished by using a fitting framework that was developed to take into account the complexity of the model and to ensure numerical stability for the algorithms used in the fitting. Since the model used in the fit contained 15 parameters and there were only three one-dimensional distributions available, we could expect multiple local minima or even whole regions of equal potential to appear. Our methods had to thoroughly explore the whole parameter space and ensure (as well as possible) that the result is a global minimum. This paper is focused on the technical aspects of the fitting strategy used. The first approach was based on a re-weighting algorithm published in article Shekhovtsova et al. and produced results in about two weeks. A later approach, with an improved theoretical model and a simple parallelization algorithm based on Inter-Process Communication (IPC) methods of UNIX system, reduced computation time down to 2–3 days. Additional approximations were introduced to the model, decreasing the necessary time to obtain the preliminary results down to 8 hours. This allowed us to better validate the results, leading to a more robust analysis published in article Nugent et al.

Opis:
The internal alpha particle beam of the heavy ion cyclotron operated by the Heavy Ion Laboratory (HIL) of the University of Warsaw has a maximum energy of 32 MeV and currently an intensity of up to 1 pμA. This beam is used by the HIL-University of Silesia collaboration for the production of research quantities of $\text{}^{211}At,$ $\text{}^{72}Se//\text{}^{72}As$ and $\text{}^{43,44}Sc$ radioisotopes. The produced activities are transported to the Institute of Nuclear Chemistry and Technology in Warsaw where research on therapeutic and imaging radiopharmaceuticals based on these radioisotopes is pursued.
