Opis:
The paper deals with the testing of composite materials based on aluminium and polymer microparticles. The aim of the research was to determine an influence of a content of a microparticle filler on mechanical properties of the polymer particle composite and adhesive bonds (material structural carbon steel S235J0). A preparation of adhesive bonds and a process of testing of the adhesive bonds were in accordance with the standard CSN EN 1465. The adhesive bond strength was increased when adding the aluminium and polymer powder filler. The adhesive bond strength increase was the highest at the adhesive bond with the adhesive in the form of the composite (15 g of the filler : 100 g of the matrix). The adhesive bond strength increase was 14.3% (13.68 ± 0.43 MPa). Adhesive bonds evinced an adhesive type of a fracture surface. By adding the filler in a form of microparticles there was a change of the failure type on adhesive-cohesive and a cohesive type. Fracture surfaces and an adhesive bond cut was examined with SEM (scanning electron microscopy) using a microscope MIRA 3 TESCAN.

Different analytical formulae have been described in the literature to modify response of Geiger-Müller (G-M) detectors. In this work, improvement of a previously proposed dead time correction formula was investigated. A set of experimental data of a decaying source was the basis of the analysis. A general agreement is seen with the experimental data. The result was compared with those obtained by the original work. Numerical aspects were also examined.

Opis:
The paper investigates the effects of degreasing, surface preparation methods in adhesive bonding and con adhesive joint strength. Five types of degreasing agents were used in the study: acetone, extraction naphtha, Ultramyt, Wiko and Loctite 7061. The degreasing operation was performed by three methods: rubbing, spraying and immersion. Strength tests were performed on single-lap adhesive joints of hot-dip galvanized metal sheets made with Loctite 9466 adhesive according to the above variants of surface preparation. The experimental results demonstrate that adhesive joint strength is significantly affected by the applied degreasing agent. Moreover, the method of application of the degreasing agent is crucial, too. The results of strength testing reveal that the most effective degreasing method for hot-dip galvanized metal sheet adhesive joints is spraying using extraction naphtha. Thereby, degreased samples have the highest immediate strength and shear strength. The use of extraction naphtha is also effective in combination with degreasing by rubbing; however, it is not effective when used in combination with immersion, as reflected in the lowest strength results.

Opis:
Dead time parameter of Geiger-Müller (G-M) counters causes a great uncertainty in their response to the incident radiation intensity at high counting rates. As their applications in experimental nuclear science are widespread, many attempts have been done on improvements of their nonlinear response. In this work, response of a G-M counter system is optimized and corrected efficiently using feed forward artificial neural network (ANN). This method is simple, fast, and provides the answer to the problem explicitly with no need for iteration. The method is applied to a set of decaying source experimental data measured by a fairly large G-M tube. The results are compared with those predicted by a given analytical model which is called hybrid model. The maximum deviation of the corrected results from the true counting rates is less than 4% which is a significant improvement in comparison with the results obtained by the analytical method. Results of this study show that by using a proper artificial neural network structure, the dead time effects of G-M counters can be tolerated significantly.

Opis:
The magnetic field and beat-treatment dependences of the ultrasound velocities at constant magnetic field (CH) and at constant magnetic induction (cB) and magnetomechanical coupling were investigated in Fe62.5Co6Ni7.5Zr6Cu1Nb2B15 alloy strips in an as-quenched state and after annealing above the Curie temperature. After annealing above 350oC (up to 390oC) the magnetomechanical coupling coefficient (k) was three times higher than that for asquenched state (0.10-012), i.e. k = 0.32-0.37. The minimum values of the cH (= 3.6 km/s) were observed after annealing in the temperature range from 350 to 390oC at 75-100 A/m. There are equal or somewhat higher values of bias field for the minimum of the cH than in some other iron-rich amorphous alloys. Effect de was very small for as-quenched samples. When the samples reached the magnetic saturation, the domain structure vanished and then the Hooke's law was valid, i.e. EH = EB = E, where E was then material constant, known as Young's modulus and then the ultrasound velocities are also material constant.

The paper investigates the compression strength of samples of regenerative polymer mass RM 101 Resimetal Metal Repair Pasta manufactured by Rendor. The effect of weather conditions on selected mechanical properties of the tested mass is examined. The samples are subjected to seasoning at room temperature, in an environmental chamber, and in a thermal shock chamber. The samples for strength testing are made according to the adopted method. It has been observed that the samples seasoned at room temperature have the lowest strength, while the highest strength is exhibited by the samples subjected to seasoning in an environmental chamber at a temperature of 70°C and humidity of 95%. In addition, the paper compares the strength properties of regenerative polymer masses manufactured by Chester Molecular, Belzona, and Unirep, as well as of the widely used epoxy compound Epidian 57 mixed with the Z-1 curing agent with those of the Rendor mass. The properties of the above masses are obtained from the available literature.

Opis:
In mid-scale and large five axis overhead gantry type milling machines, the vertical z-slide (ram) often constitutes one of the most sensitive and critical components regarding stiffness, structural vibrations and thermal influences. During machining, the z-slide is loaded by (quasi-) static process and drive forces, transient acceleration forces, periodic excitations by the tool engagement, as well as by thermal effects resulting from altering ambient conditions, heated chips, cooling lubricant and power losses in drives, guides and bearings. Deflections, thermal deformations and vibrations of the z-slide lead to geometric machining errors and inacceptable surface location errors at the workpieces. Furthermore, instable cutting conditions and regenerative chatter limit applicable material removal rates and, thus, productivity. In this work, a newly developed hybrid material structure for an exemplary z-slide, involving metal parts and mineral cast, is introduced. Structural optimization methods as well as process simulation techniques were applied in order to derive the final design solution. The integration of active cooling circuits for thermal stabilization is investigated and the use of fibre optical strain sensors is analysed with respect to a state monitoring of the machine tool component.

Opis:
Semiconductor microcavities are monolithic multilayer heterostructures grown by molecular beam epitaxy. They allow the confinement along the growth axis of both photons between the Bragg reflectors and excitons in quantum wells. If the exciton-photon coupling matrix element is large enough compared to the line width, the system is said to be in the strong coupling regime. In that case a quantum well exciton couples to another discrete state: the photon mode of a planar microcavity with the same in-plane wave vector, to give rise to quasi-stationary states named cavity polaritons. In this regime, the Fermi golden rule does not hold any more and the optical properties, linear or nonlinear, are strongly related to polariton features. A review of the optical properties of CdTe-based microcavities operating in the strong coupling regime is given in this paper. The strength of the exciton-photon coupling, dynamic optical properties, and relaxation processes along polariton dispersion curves will be discussed, as well as stimulated emission of cavity polariton luminescence.

Opis:
Recent demand for powering small sensors for wireless health monitoring triggered activities in the field of small size efficient energy harvesting devices. We examine energy harvesting in an aluminium beam with a piezoceramic patch subjected to kinematic harmonic excitation and impacts. Due to a mechanical stopper applied, inducing a hardening effect in the spring characteristic of the beam resonator, we observed a broader frequency range for the fairly large power output. Impact nonlinearities caused sensitivity to initial conditions and appearance of multiple solutions. The occurrence of resonant solution associated with impacts increased efficiency of the energy harvesting process.

Opis:
Gonads of V. pusilla at various growth stages were examined with standard histological methods. The first gonial cells appeared at the stage of 3.3 whorls: few and poorly developed gonad vesicles contained fine mitotically dividing cells and cells in meiotic prophase, with the first growing oocytes in the peripheral parts of the vesicles. At 4-whorl stage the oocytes entered vitellogenesis and increased in volume. In subadult individuals the oocyte volume and the gonad volume increased considerably; besides the advanced vitellogenic oocytes new oocytes appeared, the number of spermatids increased and the first spermatozoa were observed. The gonad of pre-reproductive adults contained numerous late-vitellogenic oocytes, young growing oocytes and many spermatozoa. In post-reproductive individuals there were no mature oocytes, spermatozoa were few, but the presence of young oocytes and mitotically dividing cells indicated resumption of gamete production.

Opis:
A human-modified environment may provide a favourable habitat for acclimation of invasive species. The resulting new niche is often unavailable for the native fauna and, consequently, can be successfully inhabited by alien invaders. This is also due to relatively low competition for food resources and space. New species inhabiting heated waters are being reported increasingly often. Recently, the presence of an Asiatic clam, Corbicula fluminalis (O. F. Müller, 1774), was confirmed in the lower course of the Odra River. This is the second taxon of the genus Corbicula found in Poland, in Western Pomerania, in a heated channel.

Opis:
We give a review on the properties and applications of M-estimators with redescending score function. For regression analysis, some of these redescending M-estimators can attain the maximum breakdown point which is possible in this setup. Moreover, some of them are the solutions of the problem of maximizing the efficiency under bounded influence function when the regression coefficient and the scale parameter are estimated simultaneously. Hence redescending M-estimators satisfy several outlier robustness properties. However, there is a problem in calculating the redescending M-estimators in regression. While in the location-scale case, for example, the Cauchy estimator has only one local extremum this is not the case in regression. In regression there are several local minima reflecting several substructures in the data. This is the reason that the redescending M-estimators can be used to detect substructures in data, i.e. they can be used in cluster analysis. If the starting point of the iteration to calculate the estimator is coming from the substructure then the closest minimum corresponds to this substructure. This property can be used to construct an edge and corner preserving smoother for noisy images so that there are applications in image analysis as well.

Two empty shells of the Asian clam Corbicula fluminea were recorded on left bank of Vistula river in Warsaw (52°17’07”N, 20°59’42”E) on 29 June, 2016 (photo 4). Altogether, 19 paired and 76 single empty valves were collected during following surveys of left and right banks of the river and two oxbows within city limits in July and August 2016. A total of 8 live bivalves were collected from the river bed and the oxbow at the depth of about 40 cm. The largest empty shell was 31.6 mm wide and 29.1 mm long. The live specimens measured 9.4-22.5 mm in width and 8.3-25.2 mm in length. The records of the Asian clam Corbicula fluminea in Warsaw document spreading of this invasive species down the Vistula River from the upper part of the river.

Opis:
Experiments on feeding rate of Deroceras reticulatum (O. F. Müller) and damage caused by this slug to oilseed rape and other plant species were carried out under laboratory conditions. No-choice tests were conducted on 20 plant species at the growth stage of 2–3 leaves. The percentage of plant damage was assessed in consecutive days of the slug feeding and the consumption index (C.I.) was calculated for each plant species and for slugs of known weight. The slug feeding rates varied significantly between the examined plant species. Papaver argemone, Sisymbrium officinale and Erigeron canadensis were the most sensitive to the slug feeding, Geum urbanum, Seneico vulgaris, Epilobium palustre and Impatiens roylei – the least so.

Opis:
The aim of the present investigation was to check the ability of experimentally farmed Helix aspersa (O. F. Müll.), raised in conditions enabling rapid growth and successful reproduction, to modulate their antioxidant defence system during enforced aestivation. The aestivation induced increase in activity of total and selenium-dependent peroxidase in the kidney and foot but did not evoke increase in activity of catalase, glutathione transferase and concentration of reduced glutathione. Moreover, the aestivation did not induce lipid and protein peroxidation, estimated as concentrations of thiobarbituric acid and carbonyl protein groups, respectively. H. aspersa farmed under favourable or natural conditions are able to modulate their antioxidant defence system in response to oxidative stress following transition from the experimental aestivation to active state.

Opis:
In the paper, Detonation of Hope, translated by Wiktoria Wojtyra, Frank M. Raddatz attempts to explain the origins of Heiner Müller’s late texts, renowned for their non-dialogue characteristics that have become the basis for the post-dramatic theater. However, this basis has been corrupted by the capitulation to violence now deeply integrated onto it. Furthermore, in Hamletmachine, Müller utilized post-utopian aesthetics as a manifestation of the thwarted hope of the end to violence in history. This fundamental structure of his narrative of violence is preceded by the long struggle against violence and the possibility of overcoming or eradicating it entirely. A profound shock ensues from a sensitization stemming from the regulation of violence set against a pandemic. However, this only succeeds until the moment in which the fight against bestiality will give way for a new desire for violence. History, it turns out, becomes a cul-de-sac as represented by the renaissance of the ice-age which marks a farewell to a utopian world free of violence. At the same time fails an alliance of art and politics. The same alliance, that on behalf of The Absolute Other once hammered out the historical expectations horizon.

Opis:
For the production of synthetic bio-fuel the use of green biomass enables additional resources of raw material supplementary to the commonly used dry material. An electroporation assisted drying process gives the opportunity of a more efficient dewatering than only pressing and subsequent drying. Experiments showed a lower relative humidity of the pressed material after electroporation compared to pressing the raw material only. Moreover, the drying process of the electroporated material was much shorter. This is because the pores formed in the cell membranes foster a better extraction of water during pressing and enhance the diffusion process during the drying process. The paper presents exemplarily the experimental results for green rye. For the electroporation-assisted drying process the electric contact to the plant material has to be established by means of the juice inside the plants only rather than adding additional water. Hence, for experiments in larger scale, the existing electroporation device KEA-MOBIL has been equipped with a new combined electroporation reactor and press. The reactor has a plate electrode system, whose upper electrode additionally serves as a piston to apply mechanical force to extract juice for a good electrical contact between plant material and the electrodes. A two-stage Marx generator serves as a pulse source. To reduce the insulation distance to the walls of the shielding cabin the Marx generator is operated in ground symmetric configuration. The device has been designed for a batch-wise throughput of 50 kg/h. An automatic feeding device enables the alternating use of two test vessels. The device has been tested on-site on a farm with green rye and grass.

The overall performance of this distributed, layer based architecture called SLAte can be increased by installing additional servers to adapt to the demands of the monitored resources and users. Another important aspect is to offer a uniform global view on all data which are stored distributed to provide an easy access for users or visualisation tools. Additionally we discus the impact of these uniform access layer on scalability.

Opis:
In Cepaea hortensis (O. F. Müller), the shell lip (peristome) is usually white. In most areas the lip colour allows us to reliably distinguish this species from C. nemoralis (Linnaeus) in which the lip is usually dark brown. Populations polymorphic for lip colour are rare and occur only locally. Here I report on populations of C. hortensis containing dark-lipped individuals in north-western Poland and in north-central Germany. The frequency of dark-lipped individuals ranged from 3% to 31%. It was common in brown and pink shells, but occurred only sporadically in yellow shells. No selective factors promoting dark-lipped C. hortensis are evident. The occurrence of this phenotype is likely to reflect random events.

In order to advance modern information technologies, progress in both the fabrication of magnetic nanostructures and of complex materials, from which small magnetic entities - like the skyrmions present in MnSi - emerge and in developing measurement techniques are desired. Here the sensor-based stray field detection using tailor-made micro-Hall magnetometers has proven to be a versatile tool for studying the magnetization reversal of individual magnetic nanostructures, domain wall motion in thin films, as well as the local stray field close to macroscopic samples. In this article we demonstrate that the local stray field can be used to accurately map out the B-T phase diagram of MnSi and serve as a guidance for simultaneously-performed electronic transport measurements. The presented study also serves as a proof-of-principle experiment for future combined investigations of electronic transport and magnetization focusing on electrically-contacted magnetic nanostructures.

Heavy-ion bombardment of thin ferromagnetic, polycrystalline films can induce substantial changes of their magnetic and microstructural properties. Since we first identified this effect in 50-150 nm thick Fe and Ni films irradiated with Xe-ions, we made a systematic search for the influence of various film and implantation parameters on the orientation and degree of the magnetic anisotropy and how these parameters correlate with the microstructure of the films. Several analyzing methods, such as Rutherford backscattering, magneto-optical Kerr effect, X-ray diffraction, magnetic force microscopy, $\text{}^{111}$In perturbed angular correlation, and conversion electron Mössbauer spectroscopy, were employed in the investigation.

The paper is devoted to the investigation of the single-electron excitation spectrum, effective exchange interaction and dielectric susceptibility of the Muller model for high-temperature superconductivity. It is shown that the interaction with the anharmonic vibration mode leads to the additional splitting of the electron bands and their narrowing. The sign of the effective exchange interaction between electrons depends on the local state of the vibration subsystem. The electron and pseudospin (lattice) contributions to the transverse dielectric susceptibility are investigated.

Opis:
In a 4f-3d ferrimagnet the molecular field (a net value expressing the relevant exchange interactions) can be determined from high-field magnetization measurements. If the applied field is high enough, it breaks the ferrimagnetic ground state and drives the system towards ferromagnetic order via non-collinear intermediate phases. Magnetization curves of $Er_2Fe_{17}$ singe crystal were measured along the [100] crystallographic direction in magnetic fields up to 50 T. An unfixed sample, free to rotate, was measured as well. The magnetization measured along the easy magnetization direction shows jumps at 37.5 and 44 T. The first jump was used for the determination of the molecular field (66.4 T). This agrees with the data for the unfixed sample where a kink in the magnetization at 33.5 T yields a molecular field of 65.7 T. The obtained values are in a good agreement with literature data.

Opis:
Familial infections with Trichomonas tenax (O.F. Müller, 1773), Dobel, 1939. Aim of the study was to research familial occurrence of Trichomonas tenax and relationship between infection with the protozoan and both a state of parodontium and hygiene of oral cavity. The study involved 10 families (22 individuals). Trichomonas tenax was found in 16 patients. Simultaneously izolates of protozoans were examined with the methods of molecular biology. The study showed the dependence of infection with Trichomonas tenax on both bad hygiene of oral cavity and occurrence of pathological lesions in the paradontium.

Opis:
Susceptibility of 18 winter wheat (Triticum aestivum L.) cultivars to damage by Deroceras reticulatum (O. F. Müll.) and Arion lusitanicus Mabille was estimated in laboratory conditions. For each slug species six experiments, two with seeds, two with seedlings at stage 07–12 BBCH and two with seedlings at stage 10–13 BBCH, were performed. The susceptibility to feeding of the two slug species differed between the cultivars; the two slugs differed in their preferences to some of the cultivars. The Nadobna cultivar was the most severely damaged by both species. The cultivars Jawa and Nutka were the least damaged by D. reticulatum and A. lusitanicus, respectively.
