    Opis:
    It is widely accepted that purinergic signaling is involved in the regulation of functions of all known tissues and organs. Extracellular purines activate two classes of receptors, P1-adenosine receptors and P2-nucleotide receptors, in a concentration-dependent manner. Ecto-enzymes metabolizing nucleotides outside the cell are involved in the termination of the nucleotide signaling pathway through the release of ligands from their receptors. The pancreas is a central organ in nutrient and energy homeostasis with endocrine, exocrine and immunoreactive functions. The disturbances in cellular metabolism in diabetes mellitus lead also to changes in concentrations of intra- and extracellular nucleotides. Purinergic receptors P1 and P2 are present on the pancreatic islet cells as well as on hepatocytes, adipocytes, pancreatic blood vessels and nerves. The ATP-dependent P2X receptor activation on pancreatic β-cells results in a positive autocrine signal and subsequent insulin secretion. Ecto-NTPDases play the key role in regulation of extracellular ATP concentration. These enzymes, in cooperation with 5'-nucleotidase can significantly increase ecto-adenosine concentration. It has been demonstrated that adenosine, through activation of P1 receptors present on adipocytes and pancreatic islets cells, inhibits the release of insulin. Even though we know for 50 years about the regulatory role of nucleotides in the secretion of insulin, an integrated understanding of the involvement of purinergic signaling in pancreas function is still required. This comprehensive review presents our current knowledge about purinergic signaling in physiology and pathology of the pancreas as well as its potential therapeutic relevance in diabetes.

    Opis:
    Ecto-purines and ecto-pyrimidines are present in the extracellular space of the central nervous system (CNS). Together with P1 and P2 receptors and nucleotides metabolizing ecto-enzymes, they make signaling system involved in neurotransmission, the modulation of sensory signals, including pain stimuli conduction, and the induction of apoptosis and necrosis of the cells. Purines and pyrimidines have a dual effect: positive (neuroprotective) of nucleosides, and negative (pro-inflammatory and pro-apoptotic) of nucleotides. Adenosine-5'-triphosphate (ATP) in the CNS triggers the pro-inflammatory reactions, predominantly by activation of the P2X7 receptor, which results in production and release of pro-inflammatory cytokines. In contrast to ATP, adenosine acts generally as an anti-inflammatory agent and plays an important role in neuroprotection. Currently, it is believed that the initiation of CNS diseases, including mental disorders, is caused by any imbalance between the concentration of ATP and adenosine in the extracellular space. Genetic tests provide also the evidence for the participation of purinergic signaling in psychiatric disorders. It is believed that any action leading to the effective increase of adenosine concentration: activation of nucleotide metabolizing ecto-enzymes (mainly NTPDases - nucleoside triphosphate diphosphohydrolases), inhibition of adenosine deaminase and/or adenosine kinase activity as well as therapies using P1 receptor agonists (adenosine or its analogues) might be beneficial in therapy of psychiatric disorders.

    Opis:
    High-quality thin Si layers obtained from the solution by epitaxial lateral overgrowth (ELO) can play a crucial role in photovoltaic applications. The laterally overgrown parts of the layer are characterized by a lower dislocation density than that of the substrate. The height and width of the layer depend on several factors, such as the technological conditions of liquid phase expitaxy (LPE), growth temperature, cooling rate and the geometry of the system (mask filling factor). Therefore, it is crucial to find the optimal set of technological parameters in order to obtain very thin structures with a maximum width (high aspect ratio). This paper presents a computational study of Si epilayer growth on a line-pattern masked silicon substrate from Si-Sn rich solution. To solve this problem, a mixed Eulerian-Lagrangian approach was applied. The concentration profile was calculated by solving the two-dimensional diffusion equation with appropriate boundary conditions. The growth velocity was determined on the basis of gradients of concentration in the border of the interface. Si interface evolution from the opened window was demonstrated.

    Ten to 16 ethanol-soluble carbohydrate components were identified in the seeds of six Mexican wild lupins. The analysed carbohydrates included: monosaccharides, disaccharides, cyclitols, galactosyl cyclitols and raffinose family oligosaccharides. Stachyose and sucrose were the main carbohydrate component in the Lupinus montanus, L. rotundiflorus, L. exaltatus, L. mexicanus and L. elegans seeds. Only trace quantities of verbascose were detected in Lupinus mexicanus seeds. The analysed seeds accumulated 38 to 78 mg/g d.m. carbohydrates. The raffinose family oligosaccharides constituted 41 to 85.2% of the identified carbohydrate component pool. The analysed Lupinus seeds contained 3 to 8 unidentified carbohydrate components.

    Opis:
    Inconel 718 is a precipitation hardenable nickel-iron based superalloy. It has exceptionally high strength and ductility compared to other metallic materials. This is due to intense precipitation of the γ’ and γ” strengthening phases in the temperature range 650-850°C. The main purpose of the authors was to analyze the aging process in Inconel 718 obtained in accordance with AMS 5596, and its effect on the mechanical properties. Tensile and hardness tests were used to evaluate the mechanical properties, in the initial aging process and after reheating, as a function of temperature and time respectively in the ranges 650°-900°C and 5-480 min. In addition, to link the mechanical properties with the microstructure transmission microscopy observations were carried out in selected specimens. As a result, factors influencing the microstructure changes at various stages of strengthening were observed. The authors found that the γ’’ phase nucleates mostly homogenously in the temperature range 650-750°C, causing the greatest increase in strength. On the other hand, the γ’ and δ phases are formed heterogeneously at 850°C or after longer annealing in 800°C, which may weaken the material.

    Opis:
    Hybrid speciation within the genus Elymus is analyzed and discussed. The supposed hybrid origin of Elymus x mucronatus between Elymus repens and Elymus hispidus was tested. In this aim, pollen viability and AFLP variation of putative progenitors and progenies from two natural populations were studied. Pollen fertility of hybrids ranging from 0 to 91.95% (average 59.50%) indicates the occurrence of F1 hybrids and backcross hybrids. Seven EcoRI/MseI AFLP primer combinations generated a total of 477 AFLP fragments (300 polymorphic) for 48 parental and hybrid individuals. UPGMA and principal coordinates analysis of the AFLP data set show that hybrids are closer to E. hispidus than to E. repens and suggest unidirectional introgression towards E. hispidus. AFLP fragments of the hybrid taxon were additively inherited from the parental species and no hybrid-specific bands were identified. AFLP analysis validates the hybrid status of E. ×mucronatus. Populations in which E. repens, E. hispidus and their hybrids co-occur still progress from early hybridization stages of F1 hybrids to an advanced hybridization stage of a well-established hybrid swarm. E. ×mucronatus is potentially self-sustaining by predominant vegetative reproduction by rhizomes and partial fertility leading to the development of mature seeds. We propose to consider Elymus ×mucronatus as a new species of hybrid origin in the Polish flora.

The analysed carbohydrates included: monosaccharides, cyclitols, galactosyl cyclitols, raffinose family oligosaccharides, lichnose family oligosaccharides, kestose family oligosaccharides. The analysed vegetative tissues accumulated from 447 to 139 mg/g d.m. soluble carbohydrates in Colobanthus quitensis, Deschampsia antarctica respectively. The raffinose family oligosaccharides constituted 53.3% in Colobanthus quitensis of the identified soluble carbohydrate component pool. Vegetative tissues accumulated starch in Colobanthus quitensis 20.6 mg/g d.m. and 261.6 mg/g d.m. in Deschampsia antarctica. Anatomical and ultrastructural observations of vegetative part of Colobanthus quitensis and Deschmpsia antarctica revealed the presence of various ergastic materials in intercellular spaces, cell walls and protoplasts. Various parts of these plants contain insoluble, PAS positive polysaccharides in intercellular spaces and in cell walls. Chloroplasts of analysed tissues contained starch. Less starch was visible in young, growing parts of shoots of Colobanthus quitensis and Deschmpsia antarctica, more starch appears in mature, differentiated parts.

    The aim of the study was to assess the thermal properties of polyester (PET) woven fabrics with unmodified (PET/AC) and flame-retardant modified (PET/AC/FR) polyacrylic coatings, before and after 1, 5, 10 & 15 washes. Differential scanning calorimetry DSC and thermogravimetric TG/DTG analyses were carried out in order to investigate the thermal processes. To evaluate the effects of the modifications and washing treatment, the scanning electron microscopy SEM/EDS technique was used. The flame-retardant modification caused that the melting enthalpy and the initial thermal degradation temperature decreased and the thermal degradation heat increased. The washing of PET/AC and PET/AC/FR fabrics caused an increase in the melting enthalpy by approximately 12% and 63% and a decrease in thermal degradation heat by about 2% and 15%, respectively. It was found that the flame-retardants were rinsed out from the coating after the fifth wash.
    Celem pracy była ocena właściwości termicznych tkaniny poliestrowej (PET) z powłoką poliakrylową, niemodyfikowaną (PET/AC) i modyfikowaną środkami trudnopalnymi (PET/AC/FR), przed i po 1, 5, 10 i 15-krotnym praniu. Do badań zastosowano techniki analizy termicznej: różnicową kalorymetrię skaningową DSC i termograwimetryczną TG/DTG oraz analizę mikroskopową SEM/EDS. Modyfikacja środkami trudnopalnymi spowodowała, że entalpia topnienia i temperatura początkowa rozkładu termicznego są niższe odpowiednio o około 11,3 J/g i 44,2 °C, a ciepło rozkładu termicznego wzrosło o około 44,6 J/g. Pranie tkanin PET/AC i PET/AC/FR spowodowało odpowiednio wzrost entalpii topnienia o około 12% i 63% oraz zmniejszenie ciepła degradacji termicznej o około 2% i 15%. Stwierdzono, że środki trudnopalne zostały wypłukane z modyfikowanej powłoki po piątym praniu.

    The authors own computer software, based on the Ueshima mathematical model with taking into account the back diffusion, determined from the Wołczyński equation, was developed for simulation calculations. The applied calculation procedure allowed to determine the chemical composition of the non-metallic phase in steel deoxidised by means of Mn, Si and Al, at the given cooling rate. The calculation results were confirmed by the analysis of samples taken from the determined areas of the cast ingot. This indicates that the developed computer software can be applied for designing the steel casting process of the strictly determined chemical composition and for obtaining the required non-metallic precipitates.

    Purpose: This study presents the residual stress analysis for the twist extrusion (TE) process after the experiment and numerical simulation and the analysis of the crystallographic texture changes and changes in hardness before and after the TE process for an RSA-501 aluminium alloy (Al; Mg5%; Mn1.5%; Sc0.8%; Zr0.4%). Design/methodology/approach: Crystallographic textures were obtained with the PANAlytical Empyrean X-ray diffractometer. The stresses were measured by applying the X-ray method with the use of using the PROTO iXRD diffractometer. Findings: The use of severe plastic deformation processes in the mass of the material leads to a significant change difference in the stress distribution in the workpiece and a change in texture compared to the reference material. The stress distribution in the sample cross-section and stress values varied and depended on the stage of the twisting process to which the surface was subjected. The highest stress (about 600 MPa) appears at the peaks of the front surface when exiting the twist area die TE. Higher stress values at the edges of the specimen are caused by friction (deformation) of the material against the die surface. The TE process strengthened – the highest crystallographic texture background level was 49%. Practical implications: The conducted tests and the obtained results allow the determination of the process parameters and critical areas of the sample by carrying out a numerical simulation. Originality/value: Microhardness increases due to the TE process and the largest values were observed at the edges. This phenomenon is confirmed by the numerical simulation results presented in this paper.

    Opis:
    The article presents research results of the introduction of powdery activated carbon to the existing technological system of the groundwater treatment stations in a laboratory, pilot plant and technical scale. The aim of the research was to reduce the content of organic compounds found in the treated water, which create toxic organic chlorine compounds (THM) after disinfection with chlorine. Nine types of powdery active carbons were tested in laboratory scale. The top two were selected for further study. Pilot plant scale research was carried out for the filter model using CWZ-30 and Norit Sa Super carbon. Reduction of the organic matter in relation to the existing content in the treated water reached about 30%. Research in technical scale using CWZ-30 carbon showed a lesser efficiency with respect to laboratory and pilot-plant scale studies. The organic matter decreased by 15%. Since filtration is the last process before the individual disinfection, an alternative solution is proposed, i.e. the second stage of filtration with a granular activated carbon bed, operating in combined sorption and biodegradation processes. The results of tests carried out in pilot scale were fully satisfactory with the effectiveness of 70–100%.

W skali laboratoryjnej przebadano 9 rodzajów pylistych węgli aktywnych, z których dwa najlepsze wytypowano do dalszych badań. Badania w skali półtechnicznej realizowano na filtrze modelowym z zastosowaniem węgli: CWZ-30 i Norit Sa Super. Obniżenie materii organicznej w stosunku do jej dotychczasowej zawartości w wodzie uzdatnionej wynosiło ok.30%. Badania w skali technicznej z zastosowaniem węgla CWZ-30 wykazały nieco mniejszą skuteczność w odniesieniu do badań laboratoryjnych i badań w skali półtechnicznej. Obniżenie zawartości materii organicznej wyniosło ok. 15%. Ponieważ ostatnim procesem jednostkowym przed dezynfekcją jest filtracja, zaproponowano alternatywne rozwiązanie – drugi stopień filtracji ze złożem granulowanego węgla aktywnego, pracującego w połączonych procesach sorpcji i biodegradacji. Rezultaty badań zrealizowanych w skali półtechnicznej były w pełni zadowalające – skuteczność 70–100%.
