    Opis:
    The aim of this study is to show the ethical aspects of the so-called normative accounting theory (NT), with particular emphasis on the ethical and normative theory (EN) important for the development of accounting as a science, taking into account its social function. Attention is focused on the so-called axiological layer with regard to the methodological foundation (pragmatic methods and related metascience) regarding the work of theorists in Western Europe. Although in the years 70s shall be considered as unscientific and begin the process of domination positive theory of accounting. It seems that in the twentyfirst century takes rebirth specific ethical and social topics in accounting. The importance and usefulness of ethics in accounting due to turbulent environment changes of accounting and social needs, as well as changes within the science.

    Opis:
    Optical spectroscopy gives a simple means to follow the evolution of the surface composition during ion beam sputtering. This is illustrated by three examples: air oxidised metals (Al and Cu), various CuAl alloys and the $Cu_{98}Be_2$ alloy. Several time scales are distinguished, corresponding to different processes: the elimination of surface contaminants, the removal of the corroded layer. The implications for the use of ion beam optical spectroscopy in surface analysis are discussed.

    Jednym z celów unijnej polityki jest stworzenie dla obywateli Unii, oprócz stabilnych warunków rozwoju ekonomicznego, także ochrony ich od zagrożeń jakie niesie współczesna cywilizacja degradująca środowisko naturalne. Hałas, zanieczyszczenia spalinami, a ostatnio także rozwój urządzeń emitujących promieniowanie elektromagnetyczne są zagrożeniami, które wymagają ujęcia ich we wspólne ramy prawne, które umożliwiają ograniczenie skutków już na etapie projektowania urządzeń i obiektów inżynieryjnych. Konsekwentne działania instytucji unijnych i rygorystyczne egzekwowanie nowych i systematycznie rosnących w swoich wymaganiach standardów technicznych przynosi po latach widoczne efekty, jak np. radykalne obniżenie szkodliwości spalin emitowanych przez pojazdy drogowe.

    Opis:
    Secondary ion mass spectrometry depth profile analyses were performed on two sets of 4H-SiC(0001) substrate samples implanted with phosphorus. Both sets were processed under the same conditions. We implanted the samples with 100 keV (10¹¹-10¹⁴ cm¯²) phosphorus ions through the thin chemical vapor deposition deposited silicon dioxide stopping mask in order to obtain an ultra-shallow implantation profile. After phosphorus implantation, secondary ion mass spectrometry depth profile analysis was performed on the first set of samples and the second set was subjected to thermal oxidation procedure at 1200°C in order to create a dielectric layer. The aim of the oxidation process was formation of the silicon dioxide layer enriched with phosphorus: the element, which is considered to be suitable for trap density reduction. Ion implantation parameters as well as oxidation and chemical etching procedures were examined for the proper incorporation of phosphorus into the subsurface structure of the silicon oxide. Secondary ion mass spectrometry depth profile analysis was performed with Physical Electronics 06-350E sputter ion gun and QMA-410 Balzers quadrupole mass analyser. The analytical parameters such as: 1.7 keV Ar⁺ ion beam digitally scanned over 3×3 mm² area and ion erosion rate of 1.4 nm/min and sampling rate of 0.3 nm, were suitable for samples oxidized after ion implantation.

    Opis:
    The following article constitutes a critical edition, translation and philological analysis of Isa 49–50 based on Coptic manuscript sa 52 and other available manuscripts in the Sahidic dialect. The first part outlines general information about the section of codex sa 52 (M 568) that contains the analysed text. This is followed by a list and brief overview of other manuscripts featuring at least some verses from Isa 49–50. The main part of the article focuses on the presentation of the Coptic text (in the Sahidic dialect) and its translation into English. The differences identified between the Sahidic text and the Greek Septuagint, on which the Coptic translation is based, are illustrated in a tabular form. It includes, for example, additions and omissions in the Coptic translation, lexical changes and semantic differences. The last part of the article aims to clarify more challenging philological issues observed either in the Coptic text itself or in its relation to the Greek text of the LXX.

    The differences in the Rutherford backscattering angular spectra measured for 100 keV hydrogen atoms H$\text{}^{0}$ and protons H$\text{}^{+}$ backscattered from Si crystal are reported and analysed. It was shown that the H$\text{}^{0}$ atom beam is better channelled in the pure crystal and is much more sensitive to the crystal surface coverage, particularly Au layer than the H$\text{}^{+}$ ion beam. The deep crystal regions seem to strengthen this differences.

    Opis:
    Ti/TiN multilayer films with a few multilayer periods and a total sub-μm thickness were deposited on AISI 304 stainless steel substrates by ion coating deposition technique. To investigate the effect of hydrogen treatment on the corrosion behavior of the multilayers, some of the samples were hydrogen treated after deposition of the first and/or the second Ti interlayer. $\text{}^{14}N(d,\alpha_1) \text{}^{12}C$ nuclear reaction and the Rutherford backscattering spectrometry were used to obtain the atomic composition profiles and thickness of Ti/TiN layers. Nuclear reaction analysis confirmed the presence of two separable TiN layers of comparable thickness on the surface and in depth of the two-period multilayers. These techniques were used to determine the thickness of individual Ti and TiN layers and revealed that the stoichiometry of TiN layers was approximately Ti:N=1:1. Hydrogen depth profile in the prepared samples was obtained by elastic recoil detection analysis. It was found that a remarkable volume of hydrogen was uptaken by the Ti layer in the hydrogen treated samples. The TiN (200) diffraction peak in the X-ray diffraction pattern was observed with different intensities depending on the sample preparation parameters. The corrosion behavior of the multilayers was studied by means of potentiodynamic polarization in 0.5 M NaCl solutions. It was found that the hydrogen treatment of Ti interlayer could potentially improve the corrosion properties of the Ti/TiN layers.

    Opis:
    The magnetocaloric effect anisotropy in the $Ni_{49.6}Mn_{27.6}Ga_{22.8}$ single crystal was investigated. In the examined alloy the structural phase transition and magnetic transition occur at room temperature and around 370 K, respectively. The magnetic entropy change, at those two temperatures, was determined on the basis of isothermal and isofield curves, recorded at fields up to 1200 kA/m (1.5 T) with temperature steps of 2.5 and 5 K. Although the calculated values of magnetic entropy change are relatively small, ≈0.7 J/(kg K), an anisotropy of the magnetocaloric effect is observed with a magnetic field applied along the main crystallographic directions of the single crystal. The magnetic entropy change at the structural phase transition depends on the orientation. The weakest magnetocaloric effect occurs when the field is applied along [1 0 0] direction whereas the highest magnetocaloric effect value is reached along [0 0 1] direction, which is an easy magnetization axis. Such behaviour can be explained with the high magnetocrystalline anisotropy of the martensitic phase. The magnetic entropy change value, at the structural phase transition, obtained for the polycrystalline specimen, is close to that for the [0 0 1] single crystal direction.

    In the paper the design and application of a time-of-flight low energy ion scattering instrument built into an UHV complex deposition and analytical apparatus is described. A special attention is aimed at demonstrating the ability of time-of-flight low energy ion scattering to analyse near-to-surface layers of thin films prepared both ex situ and in situ. It is shown that the broadening of peaks in time-of-flight low energy ion scattering spectra can be attributed to multiple scattering and inelastic losses of ions in deeper layers. As a result of that, the peak width of ultrathin films depends on their thickness.

    Opis:
    The results of X-ray diffraction studies on structural changes in the near-surface layers in the NiTi alloy caused by nitrogen-ion implantation with the energy E = 50 keV and the fluence D = $10^{18} cm^{-2}$ are presented. X-ray diffractometry, using the Philips diffractometer type X'Pert in the Bragg-Brentano geometry, was used to identify the phase composition of NiTi alloy. For layer by layer analysis of structural changes in the near-surface layers, the D8 Discover Bruker diffractometer with polycapilar beam optics was used. The ion-implanted NiTi alloy in the near-surface layer exhibits five phases: the dominating austenite phase, two martensitic phases and a small amount of the $Ni_4Ti_3$ and NTi phases. Along with the decreasing thickness of the near-surface layer investigated in material an increasing fraction of the $Ni_4Ti_3$ and NTi phases was observed. With the thickness of this layer about 340 nm, besides still existing the austenite, $Ni_4Ti_3$ and NTi phases, only one martensitic phase is present in the alloy. Further decrease of the thickness of the near-surface layer to about 170 nm leads to the increasing fraction of the $Ni_4Ti_3$ and NTi phases.

    Opis:
    Although U.S. women’s contributions to farming are vital, scholarship on U.S. female farmers is limited, especially in the U.S. South. Twelve women farmers in the Southern United States were interviewed about their experiences and opportunities in production agriculture. This study offers further nuance of the sociological and theoretical complexity and interpretive power of difference feminism and intersectionality, focusing on region and place, to a concept we call Southern Rural Feminism. Participants promote women’s equality yet acknowledge gender differences between the binary gender categories of men and women, where the uniqueness of a woman’s touch offers value to the agriculture industry. Nearly all participants’ everyday life in southern agriculture was grounded in the participants’ Christian faith, and some women used Christianity to explain gender dynamics. Within the context of the traditional rural southern culture, all women experienced differential gendered treatment in the industry, from welcomed gentlemanly behavior and gendered slights to more severe discrimination and harassment. Despite widespread gender problems, findings suggest most women do not view systematic gender oppression in the industry, do not adhere to feminist labels, and are cautiously optimistic about the future of female farmers. Incorporating theoretical discussions of Southern Rural Feminism is vital given U.S. Southern Farm Women’s restricted material access to land, and full participation in production agriculture, a field with tremendous gender inequities.

Successful Ti₂AlN monocrystalline growth was observed on GaN and Al₂O₃ substrates by annealing sputter-deposited Ti, Al and TiN layers in Ar flow at 600°C. The phase was not seen to grow when the layers were deposited on Si (111) or when the first layer on the substrate was TiN. N-type GaN samples with Ti₂AlN layers showed ohmic behaviour with contact resistivities in the range 10¯⁴ Ωcm².

    Opis:
    PbTe and its solid solution (Pb,Cd)Te containing 2% of CdTe and PbTe grown by self-selecting vapour growth technique were investigated by inelastic X-ray scattering using synchrotron radiation. The ID28 beamline at ESRF with the incident photon energy of 17794 eV and the energy resolution of 3 meV was applied for that purpose. The measurements were performed at room temperature along [001]-type high symmetry direction in the Brillouin zone. In spite of a very low energy of phonon branches they can be determined by inelastic X-ray scattering with a high accuracy. The transversal acoustic phonon dispersion obtained by inelastic X-ray scattering corresponds well to those resulting from inelastic neutron scattering measurements and ab initio calculations. Apart from expected structures corresponding to the bulk phonons an additional scattering related to the crystal surface properties was observed in the inelastic X-ray scattering spectra. The analysis performed with the use of secondary ion mass spectroscopy technique demonstrated a presence of a thin oxide layer at sample surfaces.

    Opis:
    Thin film series consisting of Ti, V, TiO₂ and V₂O₅ layer with different layer geometries, sequences and thicknesses have been prepared by the sputtering technique. The hydrogen depth profile of selected films upon hydrogen charging at 1 bar and/or hydrogenation at pressure up to 102 bar was determined by using secondary ion mass spectrometry and nuclear reaction analysis using a N-15 beam. The highest hydrogen storage with a concentration up to 50 at.% was found in the pure Ti and Ti-contained layer, while it amounts to around 30% in the metallic Ti-V-Ni layer. Hydrogen can diffuse through the TiO₂ layer without accumulation, but can be stored in the VO₂ layer in some cases. Hydrogen can remove the preferential Ti orientation in the films and induce a complete transition of V₂O₅ into VO₂ in the films.

    Opis:
    The underwater acoustic communication (UAC) operating in very shallow-water should ensure reliable transmission in conditions of strong multipath propagation, significantly disturbing the received signal. One of the techniques to achieve this goal is the direct sequence spread spectrum (DSSS) technique, which consists in binary phase shift keying (BPSK) according to a pseudo-random spreading sequence. This paper describes the DSSS data transmission tests in the simulation and experimental environment, using different types of pseudo-noise sequences: m-sequences and Kasami codes of the order 6 and 8. The transmitted signals are of different bandwidth and the detection at the receiver side was performed using two detection methods: non-differential and differential. The performed experiments allowed to draw important conclusions for the designing of a physical layer of the shallow-water UAC system. Both, m-sequences and Kasami codes allow to achieve a similar bit error rate, which at best was less than 10−3. At the same time, the 6th order sequences are not long enough to achieve an acceptable BER under strong multipath conditions. In the case of transmission of wideband signals the differential detection algorithm allows to achieve a significantly better BER (less than 10−2) than nondifferential one (BER not less than 10−1). In the case of narrowband signals the simulation tests have shown that the non-differential algorithm gives a better BER, but experimental tests under conditions of strong multipath propagation did not confirm it. The differential algorithm allowed to achieve a BER less than 10−2 in experimental tests, while the second algorithm allowed to obtain, at best, a BER less than 10−1. In addition, two indicators have been proposed for a rough assessment which of the detection algorithms under current propagation conditions in the channel will allow to obtain a better BER.

    Opis:
    Flame retardants (FRs) that have an adverse effect on human and the environment have been subject to regulation since 1972. However, FRs emerging as a replacement, are not proving to be fully environmentally safe. Water and sediment contamination by FRs, including organophosphorus (OPFRs) and novel brominated (NBFRs) ones, is a matter of major concern. Due to their common usage, many release sources, and relatively high mobility, they pose a threat to aquatic organisms and ecosystems. This review summarises studies on the OPFRs’, and NBFRs’ simultaneous occurrence in water and corresponding sediment. The main sources of occurrence and routes of entry of FRs into the environment are presented. The newest reports on the ecotoxicity of selected FRs had been summarised in order to bring the matter to attention. The research revealed that although great efforts had been made to study the occurrence of OPFRs and NBFRs in water and sediment separately, there is a lack of research on their occurrence in both media in the same area. Although major efforts have been made to study the ecotoxicity of OPFRs, there are some deficiencies for the NBFRs. Considering their relatively high ecotoxicity, further studies should be conducted on joint ecotoxicity, which may cause synergistic or antagonistic effects.

    Background. Physalis peruviana L. fruit contains nutritional and bioactive compounds of immense importance to public health and represents a potential ingredient for the development of functional foods and beverages. Objective. This study aimed to determine the chemical and nutritional composition as well as the antioxidant capacity of the P. peruviana L. fruit grown in Peru in three areas of the Central Andean region. Material and methods. Proximal and physicochemical analyses and estimation of mineral content, vitamin C, total carotenoids, total polyphenols, and antioxidant capacity (2, 2-diphenyl-1-picrylhydrazyl [DPPH] and 2, 2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) [ABTS] assays) were performed using standardized methods. Results. The fruits were collected from three regions of the Peruvian Andes (Ancash, Cajamarca, and Cusco). The results showed that the content of potassium (306.54–327.60 mg/100 g) and iron (12.93–14.47 mg/kg) was prominent. The Physalis fruit had high levels of vitamin C (47.20–52.20 mg/100 g), total polyphenols (68.17–83.40 mg equivalents of gallic acid/100 g), and carotenoids (1.12–1.73 mg β-carotene/100 g). Higher values for antioxidant capacity were obtained with the ABTS method (896–1003.33 μmol Trolox/100 g) than with the DPPH method (290–309 μmol Trolox/100 g). Conclusions. This study confirms that the P. peruviana fruit has properties that could provide important health benefits and that it could be used for the development of functional foods and food supplement.

    Opis:
    Analizując treść Listu Arysteasza do Filokratesa, można zauważyć, że zawiera on wiele wątków filozoficznych. Przede wszystkim na uwagę zasługuje określenie Prawa Mojżeszowego jako „wysoce filozoficzne”. Autor Listu wykazał, że w niczym nie ustępuje ono greckiej tradycji filozoficznej, gdyż podobnie jak grecka filozofia, tak i Prawo daje możliwość osiągnięcia cnoty. Stąd zgłębiający Prawo, znający jego treść, kierujący się jego wskazaniami to człowiek szlachetny, który w pełni zasługuje na miano filozofa. Studiowanie Prawa, kierowanie się nim oznacza zatem uprawnianie filozofii. Proprium, które wybrzmiewa z Listu, to stałe odwoływanie się do Boga Starego Testamentu jako źródła wszelkiego dobra i swego rodzaju „normy”.   
    Analyzing the content of the Letter of Aristeas to Philocrates, one can notice that it contains many philosophical threads. First of all, the description of the Mosaic Law as “very philosophical” deserves particular attention. The author of the Letter showed that the Law is in no way inferior to the Greek philosophical tradition, because, like Greek philosophy, the Law gives the possibility of achieving virtue. Hence, a person who studies the Law, who knows its content, and is guided by its norms is a noble man who fully deserves to be called a philosopher. Studying the Law, being guided by it, therefore, means practicing philosophy. The proprium that resounds in the Letter is a constant reference to God of the Old Testament as the source of all good and a “norm” of its kind.

    Opis:
    Computational examinations of the flow field in an open channel having a single Backward- -Facing Step (BFS) with a constant water depth of 1.5 m were performed. The effects of the expansion ratio, and the flow velocity along the reattachment length, were investigated by employing two different expansion ratios of 1.5 and 2, and eight various flow velocities of 0.5, 1, 2, 3, 4, 5, 7.5 and 10 m/sec in the Computational Fluid Dynamic (CFD) simulations. Commercially available CFD software, ANSYS FLUENT, was used for calculations. The simulation outcomes were verified using experimental results. Moreover, analyses were performed by using two equation turbulence closure models, K-ε family (standard, RNG and realizable), and K-ω family (Wilcox’s and SST K-ω). The analyses have revealed that the reattachment length increases with an increase in the expansion ratio, the flow velocity and the Reynolds number. The results obtained for two expansion rates and eight different flow velocities have shown insignificant differences between one turbulence closure model and the others. Furthermore, it was observed that both velocity and expansion ratios have an effect on the reattachment zone size.
