    Opis:
    W pracy scharakteryzowano siedlisko przyrodnicze źródliska wapienne ze zbiorowiskami Cratoneurion commutati (kod siedliska Natura 2000: 7220) zlokalizowane w granicach obszaru Natura 2000 Ostoja Gorczańska PLH120018, w górnej części doliny potoku Jamne. Opisano roślinność oraz podstawowe parametry siedliskowe takie jak: wysokość n.p.m., ekspozycja, nachylenie terenu, nasłonecznienie, rodzaj podłoża, sposób przepływu wody oraz wydajność wypływu (szacunkowo). W miejscach gdzie była możliwość poboru wody określono jej temperaturę, pH, przewodność elektrolityczną (PE), zawartość wapnia i magnezu (metodą absorpcyjnej spektrometrii atomowej (ASA)). Badane źródliska to obiekty o niewielkich powierzchniach (0,7–80 m2), cechujące się dużym zróżnicowaniem pod względem intensywności wytrącania się martwicy wapiennej, a także stopnia wykształcenia roślinności.
    The study gives a detail characteristic of a hard water springs habitat with the communities of Cratoneurion commutati (habitat code of Nature 2000: 7220), localized within Nature 2000 protected area Ostoja Gorczańska PLH120018, in an upper part of the valley of Jamne creek. The vegetation is described along with the main habitat parameters, namely: altitude, exposition, slope gradient, insolation, type of bedrock, water flow regime and the spring outflow efficiency. The temperature, pH, electrical conductivity were measured in the field, the concentrations of Ca and Mg in spring water were measured by Atomic Absorption Spectroscopy (AAS). The investigated headwater areas are small (0.7–80 m2) and highly differentiated by the intensity of calcareous tufa precipitation and the degree of plant cover development.

    We present the results of processing of age-momentum correlation spectra that were measured for glycerol by the gamma-induced positron spectroscopy facility. Our research has shown that the shape of experimental s(t) curve cannot be explained without introduction of the intermediate state of positronium (Ps), called quasi-free Ps. This state yields the wide Doppler line near zero lifetimes. We discuss the possible properties of this intermediate Ps state from the viewpoint of developed model. The amount of annihilation events produced by quasi-free Ps is estimated to be less than 5% of total annihilations. In the proposed model, quasi-free Ps serves as a precursor for trapped Ps of para- and ortho-states.

    Opis:
    First results in the field of synthesis and research of the multicomponent (Ti-Zr-Hf-V-Nb)N nanostructured coatings are presented in the paper. Influence of processes of spinodal segregation and mass-transfer on single-layered or multilayered crystal boundary (second phase) forming were explored. Superhard nanostructured coatings were investigated before and after annealing at the temperature 600°C using unique methods (slow positron beam, proton microbeam particle induced X-ray emission-μ, Rutherford backscattering-analysis, scanning electron microscopy with energy dispersive X-ray spectroscopy, X-ray diffraction analysis was performed using DRON-4 and nanoindentor). Diffraction spectra were taken point-by-point, with a scanning step 2Θp=0.05 to 0.1°. We detected that positron trapping by defects was observed on the nanograins boundaries and interfaces (vacancies and nanopores which are the part of triple and larger grain's boundary junction). The 3D distribution maps of elements obtained by the proton microbeam (particle induced X-ray emission-μ) together with the results obtained by slow positron microbeam gave us comprehensive information about physical basis of the processes, connected with diffusion and spinodal segregation in superhard coatings.

    Opis:
    Results of structure, phase composition, physical and mechanical properties and tribological properties investigations of nitride high-entropy coatings (TiZrHfVNb)N are presented in the paper. Proton microbeam (μ-PIXE), X-ray diffraction method, including method of X-ray strains measurements, energy dispersive X-ray spectroscopy and scanning electron microscopy analysis, microhardness testing and nanoindentation were used. Thermal annealing (t=600°C) influence on defect profiles, structure and element distribution in the coatings was investigated. It was found that thermal treatment of coatings leads to changing of defect profiles and to element redistribution. Also we can say that it influences less on grain size changing. Investigated (TiZrHfVNb)N coatings demonstrate high values of hardness and excellent wear resistance.

    Opis:
    In this investigation positron annihilation, photoluminescence and electron paramagnetic resonance techniques are employed to gain insight in the compensation of CdTe doped with the halogen Cl. We will demonstrate that the high resistivity of CdTe:Cl cannot be explained by the interaction between the shallow effective mass type donor Cl on Te site and the doping induced shallow acceptor complex, a Cd vacancy paired off with a nearest-neighbour Cl atom (A centre). From electron paramagnetic resonance investigations we conclude that the mid gap trap, often detected by electrical methods in CdTe, is not the isolated Cd vacancy.

    Positron lifetime and pressure-volume-temperature experiments were performed as function of T (100-485 K) and P (10$\text{}^{-5}$ Pa-500 MPa) on a fluoroelastomer. From positron annihilation lifetime spectroscopy, analyzed with LT9.0 assuming a dispersion in the e$\text{}^{+}$ (τ$\text{}_{2}$) and o-Ps (τ$\text{}_{3}$) lifetime, the mean, 〈v$\text{}_{h}$〉, and the width (standard deviation), σ$\text{}_{h}$, of the hole size distribution were calculated. The pressure-volume-temperature data were analyzed using the Simha-Somcynsky hole-lattice theory to estimate the specific hole free volume V$\text{}_{f}$. From a comparison of V$\text{}_{f}$ with 〈v$\text{}_{h}$〉 the specific hole number, N'$\text{}_{h}$, is estimated. The data from thermal expansion and pressure experiments show complete agreement when taking into account the compressibility of the occupied volume.

    Opis:
    The article presents the impact of viscosity of fuel on its atomization, which constitutes an important element of controlling the quality of the fuel-air mixture in compression ignition and direct injection engines. An experiment has been made using a three-hole atomizer of an engine with nominal power of 110 kW and revolutions n = 2800 min-1. Fuel was delivered by a PRW-2M injection pump intended for testing injectors. Fuel was sprayed in the atmospheric air. Three petroleum product liquids used for the experiment had a viscosity of, respectively, 3.93, 16.73 and 36.41 mm2/s. The fuel droplet size in a spray was determined by the laser diffraction method by means of a Spraytec STP 5929 analyzer. The quantity adopted for comparative purposes was the Sauter Mean Diameter D32. The results confirmed that a change of fuel viscosity within the range recommended by ship engine manufacturers has a strong impact on the size of sprayed fuel droplets. Shipowners have a limited choice of low sulphur fuel grade (up to 0.1% S), which forces the engine room personnel to use currently available fuels. Depending on the supplier, marine fuels may vary in viscosity and, according to the recommendations of engine manufacturers, they do not require heating. The increase in the size of the droplets injected into the fuel combustion chamber may affect the quality of the fuel-air mixture, increase of fuel consumption and a greater content of harmful exhaust constituents.

    The testing of cooperative transport systems is challenging because of their complexity and distributions. With TTCN3 a standard based procedure is available for specifying, executing and evaluating the testing of distributed systems such as cooperative transport systems. In the paper a standard, model and tool based solution for the testing of distributed cooperative transport systems is introduced. Based on the TTCN3 semantic, a specific model based approach for dealing with the complexity of the necessary distributed test systems was developed. With the help of some practiceoriented examples from the traffic sector this approach is presented.

    Opis:
    We here establish a new mammaliaform genus and species, Galulatherium jenkinsi (Mammalia), from the Upper Cretaceous Galula Formation in the Rukwa Rift Basin of southwestern Tanzania. This represents the first named taxon of a mammaliaform from the entire Late Cretaceous of continental Afro-Arabia, an interval of 34 million years. Preliminary study of the holotypic and only known specimen (a partial dentary) resulted in tentative assignation to the Gondwanatheria, a poorly known, enigmatic clade of Late Cretaceous–Paleogene Gondwanan mammals (Krause et al. 2003). The application of advanced imaging (μCT) and visualization techniques permits a more detailed understanding of key anatomical features of the new taxon. It reveals that the lower dentition consisted of a large, procumbent lower incisor and four cheek teeth, all of which were evergrowing (hypselodont). Importantly, all of the teeth appear devoid of enamel. Comparisons conducted with a range of Mesozoic and selected Cenozoic mammaliaform groups document a number of features (e.g., columnar, enamel-less and evergrowing teeth, with relatively simple occlusal morphology) expressed in Galulatherium that are reminiscent of several distantly related groups, making taxonomic assignment difficult at this time. Herein we retain the provisional referral of Galulatherium (RRBP 02067) to Gondwanatheria; it is most similar to sudamericids such as Lavanify and Bharratherium from the Late Cretaceous of Madagascar and India, respectively, in exhibiting relatively simple, high-crowned, columnar cheek teeth. Other features (e.g., enamel-less dentition) are shared with disparate forms such as the Late Jurassic Fruitafossor and toothed xenarthrans (e.g., sloths), here attributed to convergence. Revised analyses of the depositional context for the holotype place it as having lived sometime between the late Turonian and latest Campanian (roughly 91–72 million years ago). This enhanced geochronological context helps to refine the palaeobiogeographical significance of Galulatherium among Cretaceous mammals in general and those from Gondwanan landmasses specifically.

    Opis:
    A second specimen of the Australian cimolodontan multituberculate Corriebaatar marywaltersae from the same locality (Flat Rocks) as the holotype and previously only known specimen, reveals far more anatomical information about the species. The new specimen, composed of most of a dentary containing a complete p4 and alveoli for the lower incisor and the lower first and second molars, exhibits a suite of features consistent with allocation of Corriebaatar to Cimolodonta and further confirms the presence of multituberculates on Gondwana during the Mesozoic. The revised (older) age of the Flat Rocks locality to latest Barremian (mid-Early Cretaceous) establishes C. marywaltersae as the oldest currently known cimolodontan. This has profound biogeographic implications for the distribution of multituberculates on Gondwana as well as globally, particularly in light of the fact that Corriebaatar appears to be a relatively derived member of Cimolodonta.

    Opis:
    Single source MOCVD techniques were used to prepare perovskite films with metallic conductivity (CaRuO$\text{}_{3}$, LaNiO$\text{}_{3}$, La$\text{}_{0.5}$Sr$\text{}_{0.5}$CoO$\text{}_{3}$ and (La,Pr)$\text{}_{0.7}$(Sr,Ca)$\text{}_{0.3}$MnO$\text{}_{3}$). Structural and electrical properties of the epitaxial layers on the coherent substrates are close to that of the films grown by pulsed laser deposition and magnetron sputtering. Peculiarities of the growth occur on the worse matched substrates, such as a mixture of two orientations, each aligned in the plane of the interface (LaNiO$\text{}_{3}$/MgO) and variant structures in the films on yttrium stabilized zirconia. X-ray diffraction of the films indicates pseudocubic lattice for all R$\text{}_{1-x}$A$\text{}_{x}$MO$\text{}_{3}$ films in spite of the distortions in the bulk material. The dependence of metal-insulator transition in R$\text{}_{1-x}$A$\text{}_{x}$MnO$\text{}_{3}$ on the nature of R and A and film-substrate lattice mismatch was studied.
