    Opis:
    Badanie efektywności funduszy inwestycyjnych jest zjawiskiem dość często obserwowanym. Jednak tego typu analizy w zdecydowanej większości dotyczą funduszy akcji czy obligacji. Wydaje się, że fundusze nieruchomościowe z uwagi na to, że są stosunkowo młodym produktem na polskim rynku finansowym oraz z powodu diametralnie innego celu inwestycji powinny być przedmiotem szerokich badań. Celem prezentowanego opracowania było zbadanie efektywności wybranych funduszy inwestycyjnych lokujących swoje aktywa na polskim rynku nieruchomości w latach 2014–2016. W trakcie badań empirycznych przeanalizowano cztery wybrane fundusze inwestycyjne za pomocą relatywnych oraz bezwzględnych miar efektywności. Wyniki analizy ukazały, że większość funduszy inwestycyjnych działających na rynku nieruchomości osiągały słabe rezultaty, co może wynikać z braku umiejętności i wiedzy zarządzającego funduszem oraz złej polityki inwestycyjnej.
    The examination of the effectiveness of investment funds is a frequently observed phenomenon. However, such analyses largely concern stock and bond funds. It appears that due to their relatively young age as products on the Polish financial market and the radically different objective of investment real estate funds should be subject to extensive research. The aim of the presented study was to investigate the effectiveness of selected investment funds with assets in the Polish real estate market in 2014–2016. Throughout the course of empirical research four selected investment funds were examined using relative and absolute measurements of effectiveness. Analysis of data showed that the majority of investment funds operating on the real estate market actually achieved poor results. This may be due to a lack of prior knowledge and expertise of manager presiding over the fund, but also due to bad investment policies.

    Opis:
    The main goal of article is to investigate the Warsaw Stock Exchange market reaction to announcements in connection with planned dividend payouts. The research sample comprises 45 entities listed on the Warsaw Stock Exchange between 2017 and 2021. The analysis uses the simple rate of return and the buy-and-hold excess return. Regression analysis shows that change in DPR does not fully explain the share price changes. Nonetheless, the weak market reaction to dividend payment announcements may lead to the conclusion that Polish stocks already take into account information about dividend payouts.
    Głównym celem artykułu jest zbadanie reakcji rynku na ogłoszenia w związku z planowanymi wypłatami dywidendy. Próba badawcza obejmuje 45 podmiotów notowanych na Giełdzie Papierów Wartościowych w Warszawie w latach 2017–2021. W analizie wykorzystano prostą stopę zwrotu oraz nadwyżkową stopę zwrotu typu buy-and-hold. Analiza regresji wskazuje, że zmiana wskaźnika DPR nie wyjaśnia w pełni zmiany cen akcji podmiotów objętych analizą. Niemniej jednak słaba reakcja rynku na komunikat o wypłacie dywidendy może prowadzić do wniosku, że polskie akcje już uwzględniają informacje o jej wypłacie.

    This study is dealing with the difference of radiation chemical yields of single and double strand breaks induced in plasmid DNA by photons inside and outside of the soft X-ray water window, i.e., in the wavelength range from 2.28 nm to 4.88 nm. Photons were generated by various plasma sources providing nanosecond and sub-nanosecond pulses of extreme ultraviolet, soft X-ray and X-ray radiation. DNA strand breaks were determined by agarose gel electrophoresis. Higher radiation chemical yields of both single and double strand breaks were found using picosecond and nanosecond sources of extreme ultraviolet and X-ray radiation.

    Opis:
    Neuroblastoma is the most common extra-cranial solid tumor of childhood and it is characterized by the presence of a glycosphingolipid, GD2 ganglioside. Monoclonal antibodies targeting the antigen are currently tested in clinical trials. Additionally, several research groups reported results revealing that ganglioside-specific antibodies can affect cellular signaling and cause direct cytotoxicity against tumor cells. To shed more light on gene expression signatures of tumor cells, we used microarrays to analyze changes of transcriptome in IMR-32 human neuroblastoma cell cultures treated with doxorubicin (DOX) or a mouse monoclonal antibody binding to GD2 ganglioside 14G2a (mAb) for 24 h. The obtained results highlight that disparate cellular pathways are regulated by doxorubicin and 14G2a. Next, we used RT-PCR to verify mRNA levels of selected DOX-responsive genes such as RPS27L, PPM1D, SESN1, CDKN1A, TNFSF10B, and 14G2a-responsive genes such as SVIL, JUN, RASSF6, TLX2, ID1. Then, we applied western blot and analyzed levels of RPS27L, PPM1D, sestrin 1 proteins after DOX-treatment. Additionally, we aimed to measure effects of doxorubicin and topotecan (TPT) and 14G2a on expression of a novel human NDUFAF2 gene encoding for mimitin protein (MYC-induced mitochondrial protein) and correlate it with expression of the MYCN gene. We showed that expression of both genes was concomitantly decreased in the 14G2a-treated IMR-32 cells after 24 h and 48 h. Our results extend knowledge on gene expression profiles after application of DOX and 14G2a in our model and reveal promising candidates for further research aimed at finding novel anti-neuroblastoma targets.

    Opis:
    Air pollution has become a mass phenomenon, a major and global problem of modern society, affecting billions of people and environment. People are exposed to various levels of pollutants not just in the outdoor environment, but also in indoors. The quality of life and well-being of employees can be increased by incorporating ornamental plants in the work environment. Among the great variety of plants species able to remove/reduce indoor air pollutants Dracaena deremensis, Sansevieria trifasciata and Ficus elastica were hereby investigated. Their ability to remove chemical pollutants was evaluated in real-life conditions and the changes induced by the environmental stress on the structure and biochemical composition of the plants leaves were evidenced by the Fourier transform infrared spectroscopy. The most pronounced concentration decrease was noticed for the CO₂ (58.33% removed concentration), whereas the mean value of the removed concentration of other chemical pollutants was of ≈ 25%. The Fourier transform infrared spectra analysis revealed that, although the plants are subjected to the chemical pollutants action, they maintain the structure by adjusting their metabolism. A decrease in the overall protein contribution in the amide bands and an increase of the bands assigned to polysaccharide vibrations, illustrate the consequences of the pollution action. Moreover, the chlorophyll presence is evidenced in the IR spectra of all samples by the bands around 1040, 1445, 1620, and 1735 cm^{-1}. The results show that the Fourier transform infrared spectra are an important source of information for the rapid characterization of the chemical structure of the biological systems under environmental stress.

    Opis:
    The main objective of the presented study was to characterize the high (HAS) and low affinity (LAS) binding sites of ketoprofen (KP) in human serum albumin (HSA) structure with the use of spectrofluorescence and proton nuclear magnetic resonance spectroscopy. In vitro fluorescence analysis was used to estimate the effect of KP on the HSA fluorescence. The association constants $K_{a} [M^{-1}]$ of KP-HSA complex in the HAS were determined with the use of Scatchard, Klotz, and Hill analysis. The quenching $K_{Q} [M^{-1}]$ constants were determined on the basis of the Stern-Volmer equation. Binding of ketoprofen to plasma protein was also studied with the use of 8-anilinonapthalene-1-sulfonic acid (ANS) and 5-dimethylaminonaphthalene-1-sulfonic acid (DNSA) as the fluorescence probes in IIIA and IIA subdomains of HSA, respectively. To estimate the cooperativeness in proteins Hill's coefficient $n_{H}$ was used. The analysis of proton nuclear magnetic resonance spectra of KP in the presence of HSA allows us to observe the interactions between aromatic rings of the drug and the rings of amino acids located in the hydrophobic subdomains of the protein on the basis of the changes of chemical shifts Δ σ [ppm] of drug protons resonances. Moreover the $K_{a}$ constants $[M^{-1}]$ of KP-HSA complex in the LAS were determined.

    Opis:
    Objective: To examine the association between TYMS 2R3R polymorphism and DPYD [IVS]14+1G>A mutation by comparing healthy subjects with colorectal cancer (CRC) patients in the Mexican population. Method: Genotyping of the 2R/3R was performed by polymerase chain reaction (PCR) and [IVS]14+1G>A mutation by real-time PCR analysis. Results: The observed frequencies of the TYMS 2R3R polymorphism and the -[IVS]14+1G>A mutation in DPYD did not indicate an increased risk for CRC (p>0.05). However we observed an association of the 2R/2R (OR 3.08, 95% CI 1.66-6.08, p=0.0017) and heterozygous (OR 1.98, 95% CI 1.32-2.97, p=0.0012) genotypes as risk factors when comparing controls and CRC patients that were also tobacco consumers. An association between the genotype and the disease was evident. The distribution of the 2R/2R genotype and hematological toxicity (adjusted OR 2.26, 95% CI 1.54-4.45, p=0.0259), heterozygous (2R/3R) with tumor stage III-IV (OR 1.81, 95% CI 1.11-2.94, p=0.020) and 2R/2R-2R/3R in non-chemotherapy response CRC patients with hematological (OR 2.3, 95% CI 1.21-4.4, p=0.014) and gastric toxicities (OR 3.11, 95% CI 1.18-8.2, p=0.035) confirmed that this factor may significantly contribute to the CRC susceptibility. Conclusion: TYMS 2R3R polymorphism and the -[IVS]14+1G>A mutation in DPYD was not associated with susceptibility to CRC. However, the 2R/2R and 2R/3R genotypes of TYMS polymorphism could significantly contribute to hematological and gastric toxicity in CRC patients in this sample population.

    Opis:
    CHARACTERIZATION OF THE ORDER BY ELECTRON DIFFRACTION: In the case of a solid with a local atomic order, we can consider only a statistical description of atomic positions. For a homogeneous phase, this description is given by the two-site occupancy correlation function, the three-site occupancy correlation function, ... etc. The local atomic order is investigated by experiments in which the solid is bombarded with a well-collimated monoenergetic beam of particles (here electrons). Starting from a model describing the force law between an electron and an atomic scatterer and from a model of the solid describing the distribution of atoms in space, a computation of elastically backscattered intensities can be carried out. The latter depends on geometrical parameters which are determined in such a way that one gets the best agreement between the results of calculation and the measurements. This work aims to provide the way of proceeding to calculate the diffuse intensity. The main difficulty in this task appears when we undertake to treat the problem of multiple scattering. We provide here a detailed description of a calculation corresponding to the case of the backscattering of electrons at a single crystal surface covered with a partially disordered atomic layer. Assuming that the coverage in adatoms is small and these adatoms are weak scatterers, we can neglect the multiple scattering events inside the layer. This simplifying assumption leads to an expression of the diffuse intensity in terms of: the Fourier transform on the 2D surface lattice of the pair correlation function; the renormalized transition matrices of the different kinds of adatoms.

    We performed small angle X-ray scattering and rheological experiments in order to analyze the aggregation and denaturation processes of hen egg white lysozyme initiated by the presence of ethanol molecule. At low ethanol concentrations (below 60% (v/v)) we did not observe any change of the radius of gyration of lysozyme and no drastic changes in viscosity of the protein solution. With the increase in ethanol concentration up to the final concentration of 85% (v/v) the viscosity of protein solution dramatically increased. For high ethanol concentration a pseudoplastic behavior of lysozyme solution was observed, indicating a process of aggregation and reorientation of the protein molecules. Similar effects were observed in small angle X-ray scattering experiments. We assume that the analysis of the aggregation processes of the hen egg white lysozyme could contribute to our understanding of the mechanism of lysozyme amyloid formation.

The samples were in the form of rods with diameters of d=1.5 mm, 1 mm and 0.5 mm. It was shown that for the alloys with x=0.08 the significant magnetic hardening with the decrease of sample diameter was observed. For d=0.5 mm the coercive field equals 2.46 T and the maximum energy product $|JH|_{max}$=77.2 kJ/$m^{3}$.

    Opis:
    Temperature studies in the range 300 800 K of amorphous Fe80Nb6B14 alloy using Mössbauer spectroscopy are presented. It is shown that at a temperature close to 700 K iron clusters with non-collinear magnetic structure are formed. The observed magnetic permeability enhancement effect in the annealed at elevated temperatures alloy, which takes place in amorphous phase, is due to the strong ferromagnetic exchange between Fe clusters via the amorphous matrix and reduction of internal stresses.

    Opis:
    CuO nanoflakes were successfully synthesized by microwave irradiation, using copper(II) sulphate and sodium hydroxide (NaOH) as the starting materials and ethanol as the solvent. The CuO nanoflakes were characterized by using techniques such as X-ray powder diffraction, field emission scanning electron microscopy, and UV-visible absorption spectroscopy, Fourier transform infra-red spectroscopy. The synthesized CuO nanoflakes were found to have morphology like nanoflakes with narrow size distribution and high purity. Moreover, the synthesized CuO nanoflakes were used as an efficient catalyst for synthesis of a series of dihydropyridine derivatives. Optimization studies with different catalysts and solvents reveal that CuO nanoparticle in the water/ethanol mixture is efficient catalyst/solvent system for the synthesis of dihydropyridine derivative.

    Opis:
    The way of functioning of commercial banks remained unchanged over the years – from the institutions involved in the distribution of financial products and services turned into organizations aspiring to the title of socially responsible entities. This means that its activities include the interests of many groups, such as customers, employees, shareholders, local communities and contractors. The result is those banks that want to be recognized as socially responsible, take numerous initiatives in areas not related to the sale, such as protection of the environment, voluntary or society. The directions of banks’ activity are determined by the key values, formulated in the mission, which defines the core of the organization and lets them stand out from the competitors. Institutions socially responsible also in this area should take into account the concept of CSR by pointing to various interest groups and taking various forms of activity. The aim of the publication is to analyse the content of the missions of selected commercial banks from the perspective of the various levels of responsibility and groups of interest. The article hypothesized that not all of the analysed commercial banks include in their missions the idea of corporate social responsibility, and those that do are limited to specific areas of action and specific stakeholder groups. The analysis was conducted on the basis of the contents available on the websites of the 10 largest financial institutions in Poland in terms of assets.

    Opis:
    Strong spin-selective effects have been recently observed in both photoemission and electrical transport experiments in biomolecular systems, opening fascinating possibilities for interfacing semiconductor and biomolecular systems to create highly efficient spintronics devices. From the theoretical and experimental point of view there are strong suggestions that molecular chirality is playing a crucial role. In this study we extend a previously formulated model (R. Gutierrez, E. Díaz, R. Naaman, G. Cuniberti, Phys. Rev. B 85, 081404 (2012)) describing the linear propagation of a charge with spin along the axis of a helical charge distribution. We explore different parameter regions and show that a strong negative spin polarization as observed in the previously mentioned experiments can be obtained with reasonable values of both the electronic coupling elements and the helical field induced spin-orbit interaction.

    Opis:
    The adsorption of horse spleen ferritin on gold surface is studied with null ellipsometry and scanning electron microscopy. The high sensitivity and in situ advantage of ellipsometry make it very attractive for studies of ultrathin biomolecular layers. The influence of pH and protein concentration in solution on the adsorption kinetics was interpreted using ex situ scanning electron microscopy shots and computer modeling of the system "prism-gold film-adsorbed layer-solution". It seems that the first fast stage comprises nucleation process occurring at active sites and the following slow multistage process of a protein film growth. The data about adsorption kinetics of protein and the structure of the adsorbate layers obtained in this study enable understanding of such processes in real biological system, e.g. the protein adsorption on blood vessels and tissues in pathological processes.

    Opis:
    Biomolecular recognition is an open scientific problem, which has been investigated in many theoretical and experimental aspects. In that sense, there are encouraging results within Resonant Recognition Model (RRM), based on the finding that there is a significant correlation between spectra of the numerical presentation of amino acids in the primary structure of proteins and their biological activity. It has been found through an extensive research that proteins with the same biological function have a common frequency in their numerical spectra. This frequency was found then to be a characteristic feature for protein biological function or interaction The RRM model proposes that the selectivity of protein interactions is based on resonant energy transfer between interacting biomolecules and that this energy, electromagnetic in its nature, is in the frequency range of $10^{13}$ to $10^{15}$ Hz, which incorporates infra-red (IR), visible and a small portion of the ultra-violet (UV) radiation. In this paper, the quantum mechanical basis of the RRM model will be investigated using the solution in the simplified framework of Hückel-like theory of molecular orbits.

    The paper refers to phase stability of the $(Fe_{80}Nb_{6}B_{14})_{0.9}Tb_{0.1}$ bulk nanocrystalline alloys prepared using the vacuum suction casting technique. The samples were in the form of rods with diameters d=2, 1.5, 1 and 0.5 mm. Heating up to 900 K reveals structural changes that occur at temperatures above 680 K (DSC and M(T) measurements). The phase analysis, using Mössbauer spectra, indicates the decrease of $Tb_{2}Fe_{14}B$ and increase of Fe content in the samples after the heat treatment. The most stable is the alloy with d=1 mm, where the formation of α-Fe phase was not observed. The decrease of d causes significant hardening i.e. coercive field increases from 0.57 T to 2.66 T for d=2 mm and d=0.5 mm, respectively.

    Cryptocurrencies like Bitcoin are offering new avenues for economic empowerment to individuals around the world. However, they also provide a powerful tool that facilitates criminal activities such as human trafficking and illegal weapons sales that cause great harm to individuals and communities. Cryptocurrency advocates have argued that the ethical dimensions of cryptocurrency are not qualitatively new, insofar as money has always been understood as a passive instrument that lacks ethical values and can be used for good or ill purposes. In this paper, we challenge such a presumption that money must be ‘value-neutral.’ Building on advances in artificial intelligence, cryptography, and machine ethics, we argue that it is possible to design artificially intelligent cryptocurrencies that are not ethically neutral but which autonomously regulate their own use in a way that reflects the ethical values of particular human beings – or even entire human societies. We propose a technological framework for such cryptocurrencies and then analyse the legal, ethical, and economic implications of their use. Finally, we suggest that the development of cryptocurrencies possessing ethical as well as monetary value can provide human beings with a new economic means of positively influencing the ethos and values of their societies.

    Opis:
    Financial exclusion can be considered one of the important problems at the average level of socioeconomic development, which includes, among others, Poland. It consists in the presence of difficulties in accessing and/or using financial products and services on the main market that are suitable for the needs of individuals, and prevents them from leading a normal life in society. Due to its own characteristics and the trends in financial markets, this phenomenon is closely linked to the issue of the digital divide. Accordingly, it can be seen that solutions leading to the reduction of the financial exclusion are based on tools using information technology innovations and modern technologies. One of the methods recognized as the most effective in this area is financial education, which is aimed largely at children and adolescents, which justifies additionally the choice of such tools. It was equally important to determine the extent to which modern instruments are preferred in comparison to traditional ones. The aim of this paper will be the analysis of the solutions based on modern technologies that are used in actions taken to prevent financial exclusion in selected EU countries, including Poland. The structure of the paper is as follows: the first part will present the problem of financial exclusion (identifying groups particularly at risk), then it will review methods of preventing and combating financial exclusion, with particular emphasis on modern ICT tools, and the final part will indicate the possible directions and barriers facing the solutions that may lead to a reduced level of financial exclusion of individuals. The method made use of indepth analysis of the literature and a review of existing solutions, which financial institutions provide on the Web.

    Electron paramagnetic resonance and magnetic susceptibility measurements were performed for two $La_3Ga_{5.5}Ta_{0.5}O_{14}$ single crystals doped with 1.96 at.% of Sm³⁺ ions and 3.8 at.% of Er³⁺ ions. Two magnetically inequivalent sites were found to be responsible for the electron paramagnetic resonance spectra of Sm³⁺ ions. Both sites reveal a low (at least C₂) symmetry with $g_{x}$~0.46, $g_{y}$~0.46 and $g_{z}$~0.52. The symmetry of isolated erbium ions is higher than C₂. From electron paramagnetic resonance and magnetic susceptibility experiments it results that the ground state of Er³⁺ ions is Γ⁶ or Γ⁷. Below 51 K electronic transitions within Γ⁶ doublets take place. Between 51 and 60 K, Γ⁶ to Γ⁷ transitions dominate, while above 60 K mainly transitions within Γ⁷ doublet are active.

    Opis:
    The aim of this study was the reinterpretation of the published and unpublished Late-Pleistocene and Holocene pollen and diatom diagrams of deposits from the sedimentary basins of the Southern Baltic Sea and the correlation of the distinguished biostratigraphic units with lithological parameters, seismostratigraphic units. Chronostratigraphic subdivision of the Late Pleistocene and Holocene was also made. To facilitate the correlation and reinterpretation of the results of biostratigraphic (palynological and diatom) analyses, new unified and simplified diagrams were drawn using the POLPAL software. Such diagrams were constructed for all the sites under comparison, even for those of no numerical data. In such cases, the published diagrams were scanned and their percentage values were the basis for new diagrams. A review and reinterpretation of biostratigraphic data show an almost complete lack of palynological documentation and diatom diagrams for the Late Pleistocene period and poor documentation for the Early Holocene. Middle and Late Holocene Baltic muds have the best biostratigraphic documentation and radiocarbon dating, which greatly facilitates their location on the geological time scale. Among the Southern Baltic postglacial sediments three lithostratigraphic units were identified. They differ in their lithological features reflecting the conditions prevalent in the sedimentary basin during deposition. It should be noted that these units meet no formal criteria for distinguishing lithostratigraphic units. Similarly, within the Late Pleistocene and Holocene sediments of Southern Baltic deep-water basins, three main seismostratigraphic complexes have been identified. The integrated analysis of seismoacoustic profiles, lithological profiles of cores and reinterpretated biostratigraphic data allow a correlation of the bio-, litho- and seismostratigraphic units with chronostratigraphic units and Baltic evolutionary phases.

    The issues related to the emission of atmospheric pollutants during the provision of energy supply services and the circulation of household waste in settlements are considered. The ways of air pollution by toxic compounds and the formation of greenhouse gases with existing methods of waste heat treatment are analyzed. The issues of reducing the content of toxic emissions in combustion products are studied on the basis of a numerical experiment by means of computational fluid dynamics (CFD). The combustion processes in the power boiler TP-14A (E 220/100) are considered and adequate boundary conditions for the processes of aerodynamics, heat transfer and combustion of gas fuel are determined. The temperature, velocity and concentration fields in the furnace of the investigated boiler have been determined. According to the results of the calculations performed, the formation of chemical underburning and nitrogen oxides is predicted.

    Opis:
    Functionalised magnetic nanoparticles composed of $Fe_3O_4$ particles stabilised by sodium oleate and subsequently modified with dextran (MFDEX) were prepared by the co-precipitation method. Their morphology and particle size distribution were observed by scanning electron microscopy and photon cross correlation spectroscopy. In order to confirm the modification of magnetite surface with dextran physical techniques, including infrared spectroscopy, thermal analysis, and magnetic measurement, were used. Finally, the effect of MFDEX on amyloid fibrillar aggregates of human insulin and hen egg white lysozyme, typical amyloidogenic proteins, was investigated. In vitro interaction of MFDEX with protein amyloid fibrils resulted into destruction of amyloid aggregates. The anti-amyloid activity makes MFDEX of potential interest as therapeutic agent against amyloid-related diseases.

    Opis:
    In both theory and practice, it is emphasised that engaging in CSR actions brings many benefits to companies. One of the commonly listed advantages is more trust from investors, which enables the achievement of superior returns from securities issued by socially responsible firms. The paper endeavours to investigate whether this benefit can be also noticed among businesses in the Polish index of socially responsible companies RESPECT. The study involves firms included in the RESPECT index from its inception (November 2011) to the end of 2015. The authors compared the RESPECT index with selected Polish market indices between 2009 and 2015. Empirical studies, based on an analysis of returns, risk, dividend yields and shareholder structure, facilitated the assessment of the attractiveness of investments in the shares of socially responsible businesses against the background of other firms quoted on the Warsaw Stock Exchange.

    Opis:
    The dynamics of the lattice relaxation processes were investigated using a reflection of a high energy electron diffraction analysis system during growth by molecular beam epitaxy of ZnTe/Cd$\text{}_{1-x}$Ζn$\text{}_{x}$Te/Cd$\text{}_{0.5}$Mn$\text{}_{0.5}$Te buffers on GaAs substrates. The variation of the lattice parameter recorded by the high energy electron diffraction during the growth was later confirmed by an analysis of high resolution transmission electron microscopy images. We report also on an observation of oscillations of the lattice parameter during the deposition of several first layers of ZnTe on CdTe.

    Opis:
    Celem niniejszego artykułu jest dokonanie syntetycznej analizy prawnoporównawczej wybranych aspektów obowiązkowego raportowania krajowych schematów podatkowych w Polsce i Portugalii w związku z implementacją dyrektywy Rady (UE) 2018/822 z dnia 25 maja 2018 r. zmieniającej dyrektywę 2011/16/UE w zakresie obowiązkowej automatycznej wymiany informacji w dziedzinie opodatkowania w odniesieniu do podlegających zgłoszeniu uzgodnień transgranicznych1 (tzw. dyrektywy DAC-6). Uzasadnieniem takiego porównania jest objęciem obowiązkiem raportowania – poza schematami transgranicznymi – również schematów krajowych, co nie występuje w pozostałych krajach Unii Europejskiej (UE)2. Regulacje polskie – mimo wprowadzenia kryterium kwalifikowanego korzystającego – powodują w praktyce konieczność o wiele częstszego raportowania niż regulacje portugalskie, które nie mają takiego ograniczenia. Zwrócono szczególną uwagę na problem zawężenia zakresu tajemnicy zawodowej adwokatów, które w przypadku Portugalii jest o wiele bardziej ingerujące w ten zawód zaufania publicznego. W tym opracowaniu zastosowano metodę formalno-dogmatyczną i prawno-porównawczą do analizy przepisów dyrektywy, ustaw oraz pozostałych aktów prawnych. Zweryfikowano, które przepisy są efektywniejsze pod kątem celów wyznaczonych w dyrektywie 2018/822 oraz które wprowadzają mniejsze ograniczenia tajemnicy zawodowej. Uwzględniono również cele polskiego ustawodawcy wprowadzającego obowiązki w zakresie MDR3, w tym jego uzasadnienie konieczności istnienia takich obowiązków, nawet gdyby nie było dyrektywy 2018/822. Należy rozważyć de lege ferenda podwyższenie kary dla osób, które kierują dużymi podmiotami w Portugalii (np. będącymi częścią międzynarodowych spółek kapitałowych), a które nie raportują schematów podatkowych, oraz obniżenie kar dla pozostałych podmiotów w Polsce.
    The aim of this paper is to present a synthetic legal and comparative analysis of selected aspects of the obligatory reporting of domestic tax schemes in Poland and Portugal in connection with the implementation of the EU Directive DAC-6. The rationale for such a comparison is the extension of the reporting obligation beyond cross-border schemes to domestic schemes, which is not present in other EU countries. Despite the introduction of the qualified beneficiary criterion, the Polish regulations result in much more frequent reporting in practice than the Portuguese regulations, which do not have such a restriction. Particular attention has been paid to the problem of the narrowing of the scope of professional secrecy of lawyers, which in the Portuguese case is much more intrusive into this profession of public trust. This article uses a formal-dogmatic and legal-comparative method to analyse the provisions of the Directive, laws and other legislation. The article is used to verify which provisions are more effective in terms of the objectives of these regulations in the context of the DAC-6 Directive and which introduce less restrictions on professional secrecy. The objectives of the Polish legislator introducing MDR obligations were also taken into account due to his justification of the need for MDR even if there was no DAC-6 directive. Consideration should be given de lege ferenda to introduce a higher penalty for persons managing large entities in Portugal, e.g. those being part of international capital companies that do not report tax schemes, and lowering penalties for other entities in Poland.

    Opis:
    Positron annihilation lifetime spectroscopy has shown to be a powerful tool to study the nanostructures of porous materials. Positron emission tomograph is a device allowing imaging of metabolic processes e.g. in human bodies. A newly developed device, the Jagiellonian PET will allow positron annihilation lifetime spectroscopy in addition to imaging, thus combining both analyses providing new methods for physics and medicine. In this contribution we present a computer program that is compatible with the Jagiellonian PET software. We compare its performance with the standard program LT 9.0 by using positron annihilation lifetime spectroscopy data from hexane measurements at different temperatures. Our program is based on an iterative procedure, and our fits prove that it performs as good as LT 9.0.
