    Opis:
    Research background: In the distributive analysis, the constant relative inequality aversion utility function is a standard tool for ethical judgements of income distributions. The sole parameter ? of this function expresses a society?s aversion to inequality. However, the profession has not committed to the range of ?. When assessing inequality and other welfare characteristics, analysts assume an arbitrary level of ?, common to all countries and years. This assumption seems unjustified. Purpose of the article: This paper aims to estimate the parameter ? for each country and year individually using datasets from the Luxembourg Income Study Database in all available years, which dates back to the 1970s. Methods: We utilise the method of estimating ?, which assumes the generalised beta of the second kind distribution of incomes. The estimator of ? is derived from the mathematical condition of the existence of the social welfare function.  Findings & value added: We have elaborated an ?atlas? of  388 estimates of ? for 55 countries across time. Inequality aversion is country-year specific, with a minimum of 0.97 and a maximum of 3.8. Ninety per cent of all estimates are less than 2.5. Inequality aversion is negatively correlated with income inequality, but it is independent of economic development. Thus, inequality aversion appears as an additional dimension of the classical inequality-development relationship. This article contributes to solving a fundamental problem of Welfare Economics: directly measuring the social utility of income (welfare) function. The estimates of ? for 55 countries imply a complete knowledge of these countries' constant relative inequality aversion utility functions.

    Opis:
    Fulfilling the binding national, EU and other international regulations and requirements on climate and energy implies significant growth of renewables share in the total mix of energy production in Poland. Low-temperature geothermal energy extracted with the use of the ground source heat pumps (GSHP) is an efficient and reliable source for space heating, cooling and seasonal thermal energy storage and recovery, thus it contributes to reduction of low emissions and improvement of air quality. GSHP effectiveness is to a high degree determined by local geological and hydrogeological settings, therefore identification of natural properties of the subsurface is crucial for appropriate design and subsequent operation of the GSHP installations. The thermal conductivity λ of rocks and soils, a key geothermal parameter, depends on such features as the mineral composition of rocks and soils, their texture and water content. Relevant geological data is retrieved from thematic databases, atlases and serial maps and can be gathered in a unitary database with a uniform structure to enable spatial analysis with the use of GIS techniques. Reclassification of lithological properties into geothermal parameters and subsequent calculations of λ values (W/m·K) of rock and soil types can be made using a specific algorithm. The results of these calculations enables computation of four spatial layers of average geothermal conductivity coefficient λ (W/m·K), respectively for the depth intervals of 0-40, 41-70, 71-100 and 101-130 metres b.g.l.

    Opis:
    The aim of this paper was to investigate the corrosion resistance of Mg66Zn30Ca4 and Mg68Zn28Ca4 metallic glasses and evaluate the ability of this amorphous alloy use for medical applications as biodegradable medical implants. Taking into account the amount of Mg, Zn, Ca elements dissolved in multielectrolyte physiological fluid (MPF) from Mg66+xZn30-xCa4 (x=0.2) alloys the daily dose of evolved ions from alloys components was determined. Additional goal of the paper was determination of corrosion rate (Vcorr) and amount of hydrogen evolved from amorphous magnesium alloys in simulated environment of human body fluids during 24h immersion and during electrochemical tests. Corrosion studies were done in the multielectrolyte physiological fluid (MPF) at 37°C. The amount of hydrogen evolved [ml/cm2] and corrosion rate Vcorr [mm/year] of amorphous Mg66Zn30Ca4 and Mg68Zn28Ca4 alloys were compared. The work also presents characterization of Mg-based bulk metallic glasses structure in the form of 2 mm thickness plates. Samples structure was analyzed by means of X-ray diffraction. Fracture and surface morphology of magnesium alloy samples were identified using scanning electron microscopy.

    Opis:
    The ability of magnetic nanoparticles and their aggregates to form larger structures or new materials is primarily based on the interactions between individual particles. The article analyzes the behavior of spherical nanoparticles Fe3O4 placed in an aqueous base solution as a result of their mutual interactions, i.e. repulsive (electrostatic forces) and attractive (van der Waals forces and dipolar magnetic forces) for the full range of parameter values. Considering the application of magnetic aqueous suspensions in industry or environmental research, the presented method allows for a preliminary selection of the parameters of the dispersed material and the solution so as to obtain a suspension with the desired properties.

    Opis:
    Fossil vertebrate remains from the Keuper unit in the vicinity of the village of Krasiejów have been analyzed for almost two decades. However, the main goal of these works was focused mainly on large vertebrates. Here the authors present the first description of microvertebrate fossils from that site. The collection of around 5,000 specimens is mainly comprised of teeth and scales. The most numerous remains belong to osteichthyans: dipnoans (Ptychoceratodus and cf. Arganodus), palaeoniscids, semionotids, redfieldiids and chondrichthyans, such as Lonchidion sp., which is the first indisputable record of that genus in the Upper Triassic of Poland and the first shark at the Krasiejów locality. Tetrapod fossils consist of temnospondyl amphibians, rhynchocephalian lepidosauromorphs and archosauromorphs. Among them, temnospondyl amphibian remains are the most numerous and are represented mostly by Metoposaurus. However, on the basis of diversity in tooth morphotypes, the occurrence of other taxa cannot be excluded. Rhynchocephalians are composed of 7 fragmentary jaw morphotypes with dentition, which could indicate high taxonomic diversity (cf. Planocephalosaurus, cf. Diphydontosaurus and cf. Clevosaurus). The most varied fossil group was assigned to the archosauromorphs. The authors can distinguish at least 19 teeth morphotypes, which show similarities to the dentition of: protorosaurians (cf. Tanystropheidae), pseudosuchians (cf. Protecovasaurus, cf. Revueltosaurus), early crocodylomorphs and basal sauropodomorph dinosaurs. The first occurrence of a theropod dinosaur and cynodonts at the Krasiejów locality is also recorded. However, their remains are very rare. These new records show a high taxonomic diversity at the Krasiejów locality that contributes to our deeper understanding of Late Triassic ecosystem of Poland.

    Opis:
    Introduction: The prevalence of obesity in Poland and worldwide is constantly rising. High effectiveness of bariatric surgery has been proven in literature. It is recommended that bariatric procedures should be done by highly qualified surgeons with the appropriate, up-to-date medical equipment. Aim: The purpose of the study is to establish Polish recommendations and standards for the use of medical equipment for bariatric surgery centers. Materials and methods: The review of the present recommendations of the worldwide organizations and societies (including EAES, IFSO, SAGES) and guidelines was made. On the basis of current literature and authors’s clinical experience we proposed standardized protocol for bariatric surgical equipment. Conclusions: Relevant equipping of bariatric surgery centers and implementation of standardized perioperative and surgery protocols will result in significant improvements in bariatric treatment. This will ensure patients safety, a shorter length of hospital stay and considerably reduce the risk of morbidity. Moreover, it will contribute to the efficacy of the bariatric and metabolic surgery procedures, in accordance with the highest globally accepted standards.
