Published: March 2020

AbstractIntroductionGraft-versus-host disease (GVHD) is a common and serious complication after allogeneic stem cell transplantation (allo-SCT). However, a similar syndrome has been reported after autologous stem cell transplantation (ASCT) as well.Case reportA 61-year-old female diagnosed with immunoglobulin (Ig) G lambda multiple myeloma completed 10 cycles of bortezomib, thalidomide, and dexamethasone (VTD) and 2 cycles of cyclophosphamide, thalidomide, and dexamethasone (CTD). High-dose of melphalan (200 mg/kg) was given as conditioning, followed by an infusion of 2.5 × 106 CD34+ cells/kg. Three months later, she received her second ASCT. On Day +25 after tandem ASCT, the patient developed a maculopapular, itchy skin rash, which covered her face, trunk, and limbs. A skin biopsy was in line with the diagnosis of GVHD. The other organs were not involved. Treatment with systemic and local corticosteroids (CSs) resulted in the improvement of skin lesions, but the CSs were slowly tapered due to toxicity. In the following weeks, she developed symptoms of liver and gut involvement, which were resistant to steroids. The introduction of other immunosuppressive agents failed to achieve a response. As a consequence, she had cytomegalovirus (CMV) reactivation, as well as pancytopenia, and eventually, she died of infectious complications.ConclusionsGVHD after ASCT remains a rare but life-threatening complication with poor prognosis.

AbstractIntroductionSystemic mastocytosis (SM) with an associated hematological neoplasm (SM-AHN) constitutes about 40% of all patients with SM. AHN commonly includes myeloid neoplasms and chronic myelomonocytic leukemia (CMML) is seen in about 30% of these patients.Case reportA 67-year-old male presented to hematologist with fatigue and significant weight loss. Abdominal ultrasound and computed tomography (CT) detected hepatosplenomegaly, abdominal lymphadenopathy, and ascites. He was anemic with leukocytosis and eosinophilia. Trephine biopsy showed > 30% of spindle-shaped mast cells. TheKITD816Vmutation was present. Serum tryptase level was elevated to 62 ng/mL. The patient was diagnosed with aggressive SM and received six cycles of cladribine with partial response. Three years later, he developed severe anemia. Eosinophilia and monocytosis (5.6 × 109/L) were demonstrated in blood film. Hepatosplenomegaly and abdominal lymphadenopathy were also present. Trephine biopsy did not demonstrate the presence of spindle-shaped mast cells, but dysplasia in erythroid and myeloid lineages was evident. The histological result of lymph node biopsy as well as blood and bone marrow findings were in line with CMML. He received hydroxyurea, but he transformed soon into fatal acute monocytic leukemia.ConclusionsThe prognosis of SM-AHN depends on AHN component. Leukemic transformation of AHN component may occur in a proportion of patients.
Effect of Pulse Shape and Duration on Dynamic Response of a Forging System
Authors: Trąbka Arkadiusz 
Published: March 2020

Abstract
Forging hammers are machines whose operation causes negative effects both at the place of their foundation (the soil settlement) and in their surroundings (e.g., vibrations propagating to the other devices, noise, etc.). Knowledge of the parameters characterizing the time history of the force that arises as a result of impact of a ram on a shaped material is of fundamental importance for the correct analysis of both the structure of the hammer and its impact on the surroundings. In the paper, the effect of the shape and duration of a pulse load on the dynamic response of a hammer-foundation forging system was assessed. An analytical method of description of the forces that arise as a result of impact of the ram on the forged material, using different forms of pulses was presented. The forces defined in this way as loads in a mathematical model of three degrees of freedom forging system were used. The equations of motion derived from d’Alembert’s principle were solved numerically in the Matlab program. The analyses for eight forms of the pulse loads with the same pulse sizes but different durations were performed. The results in the graphs were presented. It was found, among other things, that a greater impact on the maximum displacement, velocity and acceleration of each component of the hammer-foundation system as well as on the maximum forces transmitted to the soil has the duration of a pulse than its shape.
Mixed Boundary Value Problem for an Anisotropic Thermoelastic Half-Space Containing Thin Inhomogeneities
Authors: Sulym Heorhiy , Pasternak Iaroslav , Smal Mariia , Vasylyshyn Andrii 
Published: March 2020

Abstract
The paper presents a rigorous and straightforward approach for obtaining the 2D boundary integral equations for a thermoelastic half-space containing holes, cracks and thin foreign inclusions. It starts from the Cauchy integral formula and the extended Stroh formalism which allows writing the general solution of thermoelastic problems in terms of certain analytic functions. In addition, with the help of it, it is possible to convert the volume integrals included in the equation into contour integrals, which, in turn, will allow the use of the method of boundary elements. For modelling of solids with thin inhomogeneities, a coupling principle for continua of different dimensions is used. Applying the theory of complex variable functions, in particular, Cauchy integral formula and Sokhotski–Plemelj formula, the Somigliana type boundary integral equations are constructed for thermoelastic anisotropic half-space. The obtained integral equations are introduced into the modified boundary element method. A numerical analysis of the influence of boundary conditions on the half-space boundary and relative rigidity of the thin inhomogeneity on the intensity of stresses at the inclusions is carried out.
Stress Concentration at Load-Carrying Fillet Welded Cruciform Joints Subjected to Tensile and Bending Loads
Authors: Molski Krzysztof L. 
Published: March 2020

Abstract
This article presents numerical finite element method (FEM) analysis of the stress concentration at toes and crack-like faults in load-carrying fillet welded cruciform joints with transversal slits resulting from non-fused root faces. Potential fatigue damage of such joints subjected to cyclic tensile and bending loads appears in the form of fatigue cracks starting from the weld roots or toes. The aim of this article is to find qualitative and quantitative relationships between geometrical parameters of the load-carrying fillet welded cruciform joint subjected to tensile and bending loads and the stress concentration at weld toes and roots. The results of the analysis represented by the stress concentration factors (SCFs) and the stress intensity factors KI and KII are shown in the form of tables, graphs and mathematical formulas, which may be applied for fatigue assessment of such joints.
Shaping the Parameters of Cylindrical Belt Surface in the Joint Area

Published: March 2020

Abstract
Most of the industrial machines use round-shaped drive belts for power transfer. They are often a few millimetres in diameter, and made of thermoplastic elastomer, especially polyurethane. Their production process requires the bonding step, which is often performed by butt welding, using the hot plate method. The authors have undertaken to design an automatic welding machine for this purpose. Consequently, it is required to carry out a process analysis of hot plate welding, which entails describing the dependency between technological parameters (temperature, pressure force, time) and the quality of the joint, especially the outer surface of the belt around the weld. To analyse this process in a proper way, it is necessary to describe the physical phenomena that occur in the material, during particular operations of the hot plate welding process. One of the most troublesome phenomena occurring during the welding process is removing of the flash. These round rings, placed around the weld, which remains after the joining process, are unacceptable in the finished component. The authors took an effort to design the necessary equipment for removing of the flash after welding, using some simple parts that cut off excessive material. The paper shows the three possible solutions for flash removal. They were verified experimentally, and afterwards, the best solution was chosen. Additionally, a number of analytical calculations were carried out in order to determine the maximum force value required for this operation. Results of the analytical calculations were compared with experimental results.

Published: March 2020

Abstract
Non-linear, dynamic, non-stationary properties characterize objects of the iron ore beneficiation line. Therefore, for their approximation, it is advisable to use models of the Hammerstein class. As a result of comparing the three models of Hammerstein: simple, parallel and recursive-parallel, it was shown that the best result for identifying the considered processes of magnetic beneficiation of iron ore by the minimum error criterion was obtained using the Hammerstein recursive-parallel model. Hence, it is recommended for the identification of beneficiation production objects.
Modelling Methodology of Piston Pneumatic Air Engine Operation
Authors: Szpica Dariusz , Korbut Michal 
Published: March 2020

Abstract
The article presents a mathematical model describing the operation of a piston pneumatic air engine. Compressed air engines are an alternative to classic combustion solutions as they do not directly emit toxic exhaust components. In the study, a modified internal combustion piston engine was adopted as pneumatic engine. The mathematical model was divided on the two subsystems, that is, mechanical and pneumatic. The mechanical subsystem describes a transformation of compressed air supply process parameters to energy transferred to the piston and further the conversion of the translational to rotary motion; in turn, in the pneumatic part, the lumped elements method was used. Calculations were carried out using the Matlab-Simulink software, resulting in the characteristics of external and economic indicators. The presented mathematical model can be ultimately developed with additional elements, such as the intake or exhaust system, as well as timing system control.
Effect of acryloylation on superabsorbency of starch copolymers
Authors: Mohammed Aliyu Danmusa , Hassan Yusuf 
Published: March 2020

Abstract
Starch is acryloylated and copolymerised without incorporating any vinyl monomer such as acrylic acid or acrylonitrile monomers to produce a superabsorbent copolymer. Fenton’s initiation system was used to produce polyacryloylated starch ester with varying degree of substitution. The copolymer from starch ester exhibited improved solubility, and an impressive water, saline, and solvents uptake. The superabsorbency of the samples is affected by the number of acryloyl groups on starch backbone. The starch ester with degree of substitution 0.8 had the highest water absorbency (102 g/g) in this experiment. Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and thermogravimetric (TGA) analyses were used to characterize the products.

Published: March 2020

Abstract
In 32 lakes, 19 watercourses and 11 estuaries located along the southern Baltic coast (NW Poland) taxa of Potomogeton and Stuckenia genera were determined on the basis of 981/0.1 m2 plant samples. Environmental factors affecting them were identified on the basis of 212 water samples and 272 sediment samples. Twenty-one Potamogeton taxa were found, including four hybrids and two Stuckenia species. Twenty-one pondweed species occurred in lakes, thirteen in watercourses and ten in estuaries. There were significant differences in environmental factors in particular types of water bodies (p<0.001) except for the content of organic and mineral matter and of humic acids in the sediment.
There was a statistically significant difference (p<0.001) between the environmental factors affecting Potamogeton and Stuckenia, respectively, within each of the waterbody types studied. In lakes, Potamogeton occupied poorer habitats than Stuckenia, with lower conductivity, redox, PAR intensity, concentration of bicarbonates, calcium and chlorides and lower calcium content in the sediment. In watercourses, Potamogeton occurred in less coloured and less oxygenated waters than Stuckenia, but richer in CO2 and chlorides, better insolated and flowing faster. It also occupied less alkaline sediment, but of higher conductivity. In estuaries, Potamogeton occurred in waters with a relatively low concentration of chlorides and calcium than Stuckenia, lower pH and conductivity, but more coloured and, consequently, with lower PAR. C&RT analysis showed mineral concentration (Ca2+, Cl−, HCO3
−) in the water, its conductivity, colour and flow to be the highest-ranking environmental factors affecting pondweeds.
Application of morphometric study to discriminatePteridium aquilinum(L.) Kuhn subsp.pinetorum(C. N. Page & R. R. Mill 1995) J. A. Thomson in Poland
Authors: Zenkteler Elżbieta , Nowak Oskar 
Published: March 2020

AbstractPteridium aquilinumsubsp.pinetorumis one of two morphologically distinct taxa of the genusPteridiumidentified in Poland. In order to confirm their distinctively recognizable morphology, nine features defining each of these taxa were subjected to a morphometric analysis. These features, including taxonomic characters of vegetative structures, were measured or counted for their most comprehensive descriptions. The measurements were also expressed as ratios of two characters (length of the first and second pairs of leaflets) to prevent the size of fronds from influencing the results. Unique features of bracken, such as: frond and pinnae shape and orientation; basal pinna structure; ultimate segment of pinnae and pinnula shape and size; frond expansion sequencing; frond lamina texture, shape and pubescence were treated descriptively. Canonical discriminant analysis was employed for a morphometric study of quantitative characters. On their basis, two taxa –P. aquilinumsubsp.aquilinumandP. a.subsp.pinetorumwere determined.

Published: March 2020

Abstract
Phytosociological and physicochemical studies of endangered habitats of swamp and peat-bog areas were carried out in the Lower Silesian Forest complex (Western Poland), in the vicinity of Węgliniec village. The total of 63 phytosociological relevés were made and three syntaxonomic units were distinguished as associations (Cicuto-Caricetum pseudocyperi, Typhetum latifoliae, Phragmitetum australis) and two as communities (with Sphagnum girgensohnii and with Juncus effusus). Using the phytoindication method, it was found that among four analysed habitat parameters (L – light availability, F – humidity, R – soil pH, N – soil nitrogen), only nitrogen content did not play a significant role in shaping the composition of these phytocoenoses. Physicochemical studies of surface waters using high performance liquid chromatography (HPLC) method indicated, among others, a higher level of nitrogen compounds in some samples. Concentrations of mineral substances dissolved in water usually exceeded limit values for class II waters. Species composition of phytocoenoses and values of parameters recorded in neighbouring surface waters indicated that mutual interactions of these habitat components clearly existed there.
Rethinking the Implications of Transformative Economic Innovations: Mapping Challenges of Private Law
Authors: Kiršienė Julija , Kelley Christopher , Kiršys Deividas , Žymančius Juras 
Published: March 2020

Abstract
This article participates in mapping existing legal implications stemming from contemporary innovation. The article relies on a case analysis of artificial intelligence, drones and blockchain, to reflect a majority of the underlying legal issues to which many emerging innovations might contribute, and it attempts to map them into different categories of challenges – liability, privacy, and property. It concludes by pinpointing three main reasons behind the identified legal implications: the growing “consciousness” and autonomy of emerging technologies, the growing availability of transformative innovations to the broad public and the development of participatory models in economy and other social spheres, including law, and the tendency for transformative innovations to function in regulatory uncertainty. As a means to cope with challenges generated by technological progress, the article leans towards a process-focused approach that promotes embedding values in the early stages of technological development.
Strengthening Judicial Cooperation in Civil Matters Between the EU and Neighboring Countries: The Example of Ukraine and the Baltic States
Authors: Izarova Iryna 
Published: March 2020

AbstractJudicial cooperation between EU Member-States and Ukraine is still at a basic level. The EU-Ukraine Association Agreement does not prove an appropriate approach, and their relations are regulated mostly with the bilateral agreements. The Baltic states and Ukraine, which are the focus of this research, are deeply engaged by their close geographical location, common historical issues and friendly relations, and seek further development of their relations. This should be accompanied by mutual judiciary trust and therefore by the corresponding evolution of bilateral relations proper to this trust. The following types of judicial cooperation in civil matters were chosen as objects of this research: recognition of Baltic States’ courts’ judgments in Ukraine, as well as service of documents and taking of evidence in Ukraine. The conclusions consist of several proposals related to deeper judicial cooperation between Member-States and third countries, illustrated by the example of the Baltic States and Ukraine, in light of the right to fair trial and mutual trust in the judiciary.
Comparison of Block Maxima and Peaks Over Threshold Value-at-Risk models for market risk in various economic conditions
Authors: Szubzda Filip , Chlebus Marcin 
Published: March 2020

Abstract
The aim of the presented study was to assess the quality of VaR forecasts in various states of the economic situation. Two approaches based on the extreme value theory were compared: Block Maxima and the Peaks Over Threshold. Forecasts were made on the daily closing prices of 10 major indices in European countries, divided into two groups: emerging countries (Bulgaria, Czech Republic, Lithuania, Latvia, Poland, Slovakia and Hungary) and developed countries (England, France and Germany). Three states of economic situation were analysed: the pre-crisis (2007), the crisis (2008) and the post-crisis (2009) period as out-of-sample. The main conclusion obtained is the too slow process of adapting static EVT-based forecasts to market movements. While in the pre-crisis period the results were satisfactory, in the period of crisis VaR forecasts were too often exceeded.
Obesity around Retirement Age: International Comparison Using SHARE
Authors: Pertold Filip 
Published: March 2020

Abstract
In this article, we aim to explain international differences in socio-demographic structure of population among people around retirement age. We further test if transition into retirement is an important factor for obesity. Using Survey of Health, Ageing and Retirement in Europe (SHARE) data, we first document that the Czech Republic has a significant and increasing trend in body mass index (BMI) and obesity (BMI > 29.99) for both men and women aged 50–70 years compared to other countries. Men have much higher level of BMI in comparison to many other European countries, whereas BMI of women is comparable to Estonia and Slovenia. However, we show a little evidence that underlying structure of Czech population with respect to education, occupation, health, age, and so on may explain increasing trend as well as higher level of obesity when compared to other European countries. Furthermore, we show that the transition into retirement is not associated with an increase in BMI. Using fixed effect model, we found that the obesity is directly related to increasing trend in obesity already before entering the retirement.

Abstract
There is a significant lack of data for the biological parameters of beluga or great sturgeon, the largest fish in the Caspian Sea. The age, growth and fisheries indices for the stock status of beluga was investigated in the south Caspian Basin of Iran between 1990 and 2011. Fork lengths ranged between 113-420 cm and weights from 8.0 to 725.0 kg. The growth parameters were L

∞
= 440 cm, K = 0.027 year−1, t

= − 5.8 years. The age at first capture (t

c
) was 13.1 years. The long-term age composition data showed age up to 63 years, and the ages 12-19 years comprised 76.7% of the total catch. The generation length was 33 years. The values of “KF” were close to 1 or >1, indicating that beluga sturgeon is in a favorable condition in the southern Caspian Sea. The length distribution showed that 24.2% of the catch is comprised of juveniles. Based on the age structure and age at first maturity, recruitment and growth overfishing occurred in beluga stocks. Therefore, increased length or age at first capture in future fishery policies should be implemented. The mega-spawners represented 4.4% of the fish captured and revealed an unhealthy population structure.
