Abstrakt: Serotonin 5-HT1A and 5-HT7 receptors play an important role in the pathogenesis and pharmacotherapy of depression. Previously identified N-hexyl trazodone derivatives, 2-(6-(4-(3-chlorophenyl)piperazin-1-yl)hexyl)-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one hydrochloride (7a·HCl), with high affinity for 5-HT1AR and 2-(6-(4-([1,1′-biphenyl]-2-yl)piperazin-1-yl)hexyl)-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one hydrochloride (7b·HCl), a dual-acting 5-HT1A/5-HT7 receptor ligand, were prepared with a new microwave-assisted method. The protocol for the synthesis of 7a and 7b involved reductive alkylation under a mild reducing agent. We produced the final compounds with yield of 56–63% using ethanol or 51–56% in solvent-free conditions in 4 min. We then determined the 5-HT7R binding mode for compounds 7a and 7b using in silico methods and assessed the preliminary ADME and safety properties (hepatotoxicity and CYP3A4 inhibition) using in vitro methods for 7a·HCl and 7b·HCl. Furthermore, we evaluated antidepressant-like activity of the dual antagonist of 5-HT1A/5-HT7 receptors (7b·HCl) in the forced swim test (FST) in mice. The 5-HT1AR ligand (7a·HCl) with a much lower affinity for 5-HT7R compared to that of 7b·HCl was tested comparatively. Both compounds showed antidepressant activity, while 5-HT1A/5-HT7 double antagonist 7b·HCl showed a stronger and more specific response.]]>

<![CDATA[Lighting of pedestrian and pedestrian-driving routes in a housing estate as a source of light pollution]]> Tue, 29 Nov 2022 11:00:48 +0100 Ściężor, Tomasz
rodzaj: artykuł w czasopiśmie
Abstrakt: This paper is devoted to the extremely important issue of lighting pedestrian and pedestrian-driving routes within a housing estate. Both aspects are discussed with regard to the safety of route users and the potential impact on the natural environment through the phenomenon of light pollution. It was found that most of the outdated high-pressure sodium lamps present in the analysed Podwawelskie housing estate in Kraków do not fulfil their basic purpose, which is to sufficiently illuminate the ground below. Nevertheless, the light of these lamps does not make a noticeable contribution to the basic form of light pollution, which is the city's sky glow. It has been suggested that it would be best to replace these types of lamps with LED lighting, which has already been partly done. The LED lamps provide lighting that is sufficient to ensure the safety of residents. However, their improper installation may cause glare for pedestrians or residents of neighbouring houses. Additionally, their light reflected from an excessively bright pavement makes a significant contribution to the artificial sky glow. Solutions are proposed that minimise the negative impact of this lighting on the environment while ensuring comfort for the residents of the estate, which is in line with the principles of sustainable development.]]>
<![CDATA[Investigating urban form, and walkability measures in the new developments. The case study of Garnizon in Gdansk]]> Mon, 28 Nov 2022 14:12:38 +0100 Poklewski-Koziełł, Damian; Dudzic-Gyurkovich, Karolina; Marmolejo Duarte, Carlos

Abstrakt: Sustainable transport choices are gaining much attention as they may support the global shift towards reducing the carbon footprint and developing more energy-efficient cities. The relation between urban form and sustainable transport has been discussed by academics and practitioners and there is a consensus that specific parameters of urban form can encourage walking and discourage car use. Following global recommendations on sustainable development, countries take steps towards strengthening pedestrian accessibility by implementing spatial characteristics of walkable neighbourhoods, but also by mobility and urban design strategies. This issue, however, is not properly recognised in countries with short experience in sustainable urban development, such as former socialist countries. In Poland no studies on walkability-related parameters of urban form have been carried out, hence the knowledge in this field is limited. This paper aims to address this gap by providing evidence of a newly built urban district located in Gdansk, Poland. We present the Polish case with three examples of new urban districts from Western Europe, that are designed as sustainable and walkable environments. The methodology is based on the descriptive case study. It includes characteristics of design parameters namely the components of the “walkability index” as well as mobility solutions and urban design guidelines. The results show the current position of Garnizon development in relation to the Western European cases with regard to the existing post-communist legacy and allow for indicating differences and possible shortcomings. Additionally, the study results can be discussed in the context of improving the quality of the housing environment in Poland through pedestrian-oriented development strategies.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Due to the widespread occurrence and the potential threat to the environment, plastic materials are currently a growing problem of environmental protection in the world. Plastics whit dimensions not exceeding 5 mm are called microplastics. One of the main sources of microplastics in the aquatic environment are municipal wastewater treatment plants. The paper presents the results of research on the presence of microplastics in leachate from sludge processing at a large municipal wastewater treatment plant. The leachate was divided into the leachate produced in the processes of sludge thickening and dewatering. The analysis of the isolated microplastics included a physical analysis, which focuses on determining size, shape, and color of the isolated material. The next step was the chemical identification of the microplastic, where the type of polymer of the tested material was confirmed by means of Attenuated Total Reflection Fourier Transform Infrared. Among the isolated microplastic particles, almost a half was identified as fragments, and a smaller amount was confirmed for the presence of foil, fibers, foams and granules. The identified particles were plastic materials, including polypropylene, polyethylene, polystyrene or poly(terephthalate). Based on the results of the conducted research, the mass of microplastics in leachate was characterized and determined.]]>

Abstrakt: Cooperation of an university and a private company resulted in developing of composite skeleton made of spruce wood of C24 class and polymer flexible adhesive, being innovative solution investigated during a project in Poland. Structural elements were constructed using flexible adhesive layers made of special two component polyurethanes of 3 mm thickness and installed in prototype timber houses. Carried out research on this innovative solution indicated that flexible bonding of wood can be applied in civil engineering practice. Following this idea, new research was carried out at Cracow University of Technology in Poland focusing on parametric analysis of flexible bonding using in structural connection of Douglas Fir wood (Pseudotsuga Carriere) and flexible polyurethane Sika PS. Tested specimens were constructed in form of beams with three various flexible adhesive thicknesses of 1 mm, 2 mm and 4 mm. The beam specimens were tested in bending under elevated temperatures of 20, 40, 60 and 80 Celsius degrees, resulting in load capacity and deflection measurements. Nonlinear behavior of tested flexible adhesives provided advantageous stress concentration reduction and even stress redistribution along the bond-line. Basing on the obtained results, various specimens numerical modeling of the innovative system. Finite Element Method numerical models were calibrated using experimental results and analysis allowed to visualize phenomenon of structural flexibility, which manifested promising properties in behavior of structural elements made of wood and flexible adhesives. Carried out research is aimed on developing of new wood-adhesive technology, more advantageous than classical systems using stiff and very thin layers of adhesives.]]>

Abstrakt: Tradycyjne systemy dostarczania substancji aktywnej wiążą się z ograniczeniem terapeutycznego działania leku. Spowodowane jest to m.in. dystrybucją danej substancji w całym organizmie oraz szybkim jej uwolnieniem skutkującym krótkotrwałym działaniem leku. Rozwiązaniem tych problemów jest stosowanie odpowiednich nośników substancji aktywnej. Odpowiednio zaprojektowany nośnik umożliwia dostarczenie substancji aktywnej w sposób kontrolowany. Zapewnia to transport leku do określonego miejsca oraz jego uwolnienie w przedłużonym czasie. W pracy otrzymano nośniki polimerowe na bazie chitozanu i żelatyny modyfikowane zawiesiną nanosrebra oraz ekstraktem roślinnym Hypericum perforatum. Materiały otrzymano w procesie polimeryzacji w polu promieniowania mikrofalowego.

Abstrakt: Although artificial neural networks are widely used in various fields, including mining and mineral processing, they can be problematic for appropriately choosing the model architecture and parameters. In this article, we describe a procedure for the optimization of the structure of a convolutional neural network model developed for the purposes of metallic ore pre-concentration. The developed model takes as an input two-band X-ray scans of ore grains, and for each scan two values corresponding to concentrations of zinc and lead are returned by the model. The whole process of sample preparation and data augmentation, optimization of the model hyperparameters and training of selected models is described. The ten best models were trained ten times each in order to select the best possible one. We were able to achieve a Pearson coefficient of R = 0.944 for the best model. The detailed results of this model are shown, and finally, its applicability and limitations in real-world scenarios are discussed.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Sustainable rainwater management is made possible, among others, by nationwide and local policies and regulations that create economic incentives. This article analyzes how existing economic instruments in Poland motivate property owners to make investments that manage rainwater on their own properties. Two types of investments were analyzed: bioswales as one of the lowest-cost green infrastructure measures in construction and operation, and the rainwater harvesting solution that uses rainwater to irrigate greenery. Simulation of this type of investment was undertaken in response to existing economic incentives – obtainable discounts of national and municipal rainwater drainage fees and municipal subsidy programs for rainwater management from three cities of different sizes selected from the Greater Poland province. Analyses were carried out for three types of development: different intensity, sealing of the land, and number of residents. The financial profitability of the investment was evaluated by determining the payback period, NPV, and benefit–cost ratio, taking into account the possible discounts in fees and investment subsidies in the variant analyses. It was shown that the incentive function of national fees for rainwater drainage is low, and that the incentive function of municipal fees and subsidies is higher, depending on the design of the fee (rates and discounts) and subsidy (directions and level of subsidies) systems.]]>

Abstrakt: Due to the presence of actuator disturbances and sensor noise, increased false alarm rate and decreased fault detection rate in fault diagnosis systems have become major concerns. Various performance indexes are proposed to deal with such problems with certain limitations. This paper proposes a robust performance-index based fault diagnosis methodology using input–output data. That data is used to construct robust parity space using the subspace identification method and proposed performance index. Generated residual shows enhanced sensitivity towards faults and robustness against unknown disturbances simultaneously. The threshold for residual is designed using the Gaussian likelihood ratio, and the wavelet transformation is used for post-processing. The proposed performance index is further used to develop a fault isolation procedure. To specify the location of the fault, a modified fault isolation scheme based on perfect unknown input decoupling is proposed that makes actuator and sensor residuals robust against disturbances and noise. The proposed detection and isolation scheme is implemented on the induction motor in the experimental setup. The results have shown the percentage fault detection of 98.88%, which is superior among recent research.]]>

Abstrakt: We present a group of seven new advanced symmetric iodonium salts bearing two benzylidene-based chromophores. This is the first example of the use of a double bond in the structure of a symmetric iodonium salt. Such an improvement ensures excellent absorbing properties in the UV-A and visible range, representing a significant advance over the commonly used diaryliodonium salts. New symmetric iodonium derivatives effectively photoinitiate cationic polymerization using light-emitting diodes (LEDs) with no additives. Thus, they can act as one-component photoinitiators even in visible light, where common diaryliodonium salts remain inactive. They can be used in advanced applications such as three-dimensional (3D) VAT printing using an LCD printer. In addition, it was possible to study in detail substituent effects on the properties of the new iodonium salts due to the easily modifiable structure of the benzylidene chromophore. The research described represents a significant advance in the development of iodonium salts.]]>

At large transverse momentum of gluons we match the so-obtained distribution to the logarithmic derivative of the collinear gluon distribution. We check our approach by calculating the proton structure function FL (x, Q 2) finding good agreement with HERA data.]]>

Abstrakt: Modelowanie to graficzna reprezentacja procesów w organizacji z wykorzystaniem dostępnych reguł i zasobów, dlatego ważne jest, aby do opisu modeli procesów, decyzji i oprogramowania używać uniwersalnego i kompleksowego standardu. Dostępne różne notacje do projektowania systemów informatycznych mogą zawierać nieścisłości oraz problemy związane z integracją różnych notacji i zachowaniem spójności pomiędzy nimi. Aby temu zapobiec istnieje potrzeba zdefiniowania nowej metodyki modelowania systemu biznesowego. Dzięki czemu zostanie osiągnięta wspólność metodyk na podstawie wyodrębnionych wspólnych cech diagramów. Mając to na uwadze jako główny cel badań wskazano możliwość integracji notacji OMG do projektowania systemów informatycznych z użyciem następujących notacji: UML, BPMN, DMN i CMMN. W pracy dokonano analizy dostępnej literatury opisującej aktualny stan wiedzy o notacji BPMN oraz przedstawienie problemów i niedociągnięć związanych z tym tematem.]]>

Abstrakt: PolyUrethane Flexible Joints (PUFJ) and Fiber Reinforced PolyUrethanes (FRPU) have been manifested their high efficiency in bonding and strengthening of structural elements for last years, assuring simultaneous transfer of high loads and high deformations. They can be used in structural and non structural bonding of various structural materials as concrete, masonry and wood. Many research and in situ applications confirmed they innovative and unique characteristics in civil engineering. PUFJ and FRPU systems are considering now as testing products in frame of a MEZeroE project (MEZeroE - measuring envelope products and systems contributing to the next generation of healthy nearly-zero-energy buildings) funded by European Commission in Horizon 2020 program. PUFJ and FRPU are proposed as new structural and non structural bonding systems or joints in wood constructions, mainly in envelopes of nearly-zero-energy buildings. PUFJ system can be applied as injection or prefabricated laminates creating wood-to-wood, wood-to-concrete or wood-to-masonry bonds. They can form thin or thick flexible adhesive bondlines with adjusted properties. FRPU system is dedicated quick repair intervention or strengthening as it uses high strength fibers and flexible polyurethane matrix for externally bonded composites. Special polyurethanes using in PUFJ and FRPU can work safely under various loads (strong winds, earthquakes) and manifest stable properties in elevated temperatures. They are dedicated to bonding of CLT panels, where they can replace steel connectors, providing thermal and humid problems and pure resistance to cyclic loads. In the paper, properties of PUFJ and FRPU systems are presented with examples of connections, planned to be tested at Cracow University of Technology in a Pilot Measurement and Validation Line (PM&VL) of the MEZeroE project. Presented connection solutions bond wood elements with other wood, concrete and masonry elements, providing advantageous hydro-thermal properties.]]>

Abstrakt: Perovskite nanomaterials with highly stable and bright emission were requested for white light emitting diodes (LEDs). In this paper, superior thin CsPbBr3 nanoplates (NPLs) with an average thickness of 1.9 nm were synthesized via solvothermal reactions. A bright blue-emitting peak at 455 nm with a photoluminescence (PL) quantum yield of 89 % was observed. The high PL efficiency was kept after storing for 90 days at ambient condition. This supplied an efficient approach to solve the problem of low PL efficiency and poor stability of blue-emitting perovskite nanocrystals. The thickness of CsPbBr3 NPLs was adjusted by changing preparation conditions. The PL peak wavelength of CsPbBr3 NPLs was adjusted in a region of 455–465 nm. Through dynamic anion exchange promoted cation exchange reactions, Mn ions were introduced in the lattice of CsPbBr3 NPLs to generate bright orange emitting to create dual-luminescent CsPbBr3:Mn NPLs. A white emitting sample with a color coordinate of (0.304, 0.325) was finally fabricated using bright CsPbBr3:Mn NPLs and green-emitting CsPbBr3 nanocrystals. This work broadened the application of perovskite for display and lighting.]]>

Rentgenograficzne badania składu fazowego potwierdziły, że głównym składnikiem produktów kalcynacji jest hydroksyapatyt. Zawartość fosforu w produktach po kalcynacji utrzymuje się na poziomie zbliżonym do stężenia tego pierwiastka w typowych surowcach fosforowych, co potwierdza celowość wykorzystania odpadów z przemysłu mięsnego jako substytutu surowców fosforowych. Badania morfologii popiołów otrzymanych w różnych temperaturach wykazały, że temperatura kalcynacji nie wpływa w sposób istotny na ich własności. We wszystkich przypadkach otrzymano produkt drobnokrystaliczny, o zbliżonym kształcie i wielkości ziaren. Jedynie popioły kalcynowane w 1223K charakteryzowały się lekko nadtopionymi krystalitami.]]>

Abstrakt: Here we present a combined experimental and ab initio lattice dynamics study of the semiconducting β phase of FeSi2. A polycrystalline β-FeSi2 film was prepared on Si(111) and single-crystalline, self-assembled β-FeSi2 nanorods were grown on Si(110) by molecular beam epitaxy. Both types of nanostructures were obtained by annealing of precursor structures, an epitaxial Fe film in the case of the film and high-aspect-ratio α-FeSi2 nanowires in the case of the nanorods. The morphology and crystalline structure of the samples were investigated by reflection high-energy electron diffraction, atomic force microscopy, as well as x-ray diffraction and x-ray absorption spectroscopy. The Fe-partial phonon density of states (PDOS) was obtained from nuclear inelastic scattering. The PDOS of the film was investigated in the temperature range of 296 K down to 11 K and shows an excellent agreement with the ab initio calculations. In the PDOS of the nanorods, a shift in the number of states in the main features and an additional vibrational mode at 20 meV are observed. While the first effect can fully be explained by the specific orientation of the β-FeSi2 unit cell on the Si(110) surface, the second effect is attributed to the formation of an α-FeSi2 interlayer at the β-FeSi2/Si interface. Furthermore, the thermoelastic properties of the film show a harmonic behavior in the investigated temperature range. For the nanorods, no significant deviation from the film is observed, except for a small decrease of the sound velocity.]]>

Abstrakt: The early and accurate detection of COVID-19 is vital nowadays to avoid the vast and rapid spread of this virus and ease lockdown restrictions. As a result, researchers developed methods to diagnose COVID-19. However, these methods have several limitations. Therefore, presenting new methods is essential to improve the diagnosis of COVID-19. Recently, investigation of the electrocardiogram (ECG) signals becoming an easy way to detect COVID-19 since the ECG process is non-invasive and easy to use. Therefore, we proposed in this paper a novel end-to-end deep learning model (ECG-COVID) based on ECG for COVID-19 detection. We employed several deep Convolutional Neural Networks (CNNs) on a dataset of 1109 ECG images, which is built for screening the perception of COVID-19 and cardiac patients. After that, we selected the most efficient model as our model for evaluation. The proposed model is end-to-end where the input ECG images are fed directly to the model for the final decision without using any additional stages. The proposed method achieved an average accuracy of 98.81%, Precision of 98.8%, Sensitivity of 98.8% and, F1-score of 98.81% for COVID-19 detection. As cases of corona continue to rise and hospitalizations continue again, hospitals may find our study helpful when dealing with these patients who did not get significantly worse.]]>

Abstrakt: In this work, the efect of functionalized hydroxyapatite (HAp-g-PEG) on the thermal degradation behaviour and fammability of polyoxymethylene copolymer (POM_C) was investigated. Organic–inorganic hybrid additive, obtained by grafting of poly(ethylene glycol) on HAp surface using 1,6-hexamethylene diisocyanate as a linker, has been incorporated into POM matrix through an extrusion process. TG analyses show that the incorporation of HAp-g-PEG into POM_C leads to the signifcant improvement in the thermal stability of the polymer matrix. This is an important fnding as POM, being an engineering polymer, sufers from a relatively low thermal stability that limits processing options to develop advanced composite materials. Based on TG results kinetic parameters of the thermal degradation process using Friedman isoconversional method and nonlinear regression method have been calculated; an increase in activation energy of POM degradation process after incorporation of HAp-g-PEG has been found. Thermoanalytical analyses (TG-FTIR/MS) show that incorporation of HApg-PEG has no signifcant efect on the composition of the thermal degradation products. Flammability investigations showed small efect of HAp-g-PEG 600 on the burning time and rate, however, there was a signifcant reduction in the amount of dripping during the material’s burning process.]]>

rodzaj: rozdział/fragment książki
Abstrakt: Architects try to pass for innovators. Novelty and the negation of memorised shapes have always been part of the artists’ activities. But can architecture and art change eternally? There are moments in art when recalling familiar shapes, though in new scales and other colours, is considered a path to novelty. Duchamp showed the artists the possibility of using a new path to uniqueness. However, his games with objects were sometimes unsightly, which is a somewhat questionable path in architecture addressed to a mass audience. Thus, familiar shapes appear in contemporary architecture and the slightly earlier one presented in a different, more innovative way. Novelty does not necessarily arise through the negation of the ‘old’. Architects want to create works that resemble nothing, yet are embraced by the public. This is a dilemma for the creators: they want to be avant-garde, but investors require them to build a form suitable for advertising. Perhaps this will be a rediscovered path for the emergence of other unknown architecture.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Lignin, a highly aromatic macromolecule building plant cells, and cellulose are two of the most commonly occurring natural polymers. Lignosulfonate is a grade of technical lignin, obtained as a by-product in the paper and wood pulping industries, a result of the used lignin isolation method, i.e., sulfite process. In this work, sodium lignosulfonate is used as a starting material to manufacture sulfonamide derivatives of lignin in a two-step modification procedure. Since this direction of the lignin modification is rather rarely investigated and discussed, it makes a good starting point to expand the state of knowledge and explore the properties of lignosulfonamides. Materials obtained after modification underwent characterization by FTIR, SS-NMR, WAXD, SEM, and TGA. Spectroscopic measurements confirmed the incorporation of dihexylamine into the lignin structure and the formation of lignosulfonamide. The crystalline structure of the material was not affected by the modification procedure, as evidenced by the WAXD, with only minute morphological changes of the surface visible on the SEM imaging. The obtained materials were characterized by improved parameters of thermal stability in relation to the raw material. As-prepared sulfonamide lignin derivatives with a potential application as a filler in biopolymeric composites may become a new class of functional, value-added, sustainable additives.]]>

Literature research and the analysis of implementation prove that social ideas, the negation of historicizing forms and traditional urbanism as an emanation of oppression were at the source of the avant-garde movements of the 20th century. Following the strangeness of the form, for a hundred years the social sensitivity was lost. An analysis of the recent architectural awards proves the rejection of the mainstream of star architecture. As a result, it cannot be proved whether this means the death of the avant-garde.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The main novelty of this study is producing Ultra High-Performance Self Compacting Mortar (UHPSCM) incorporated Recycled Steel Fibre (RSF) from waste tires. For this purpose, different mix compositions including 0%, 1%, and 3% RSF content in terms of volume were proposed. Self-compacting ability was assessed using mini-cone tests, while nondestructive testing has been used to evaluate the effect of RSF inclusion on the compaction of UHPSCM constituent materials. Mechanical performances were investigated using compression and unnotched flexural tests. Residual flexural strength in both service limit state (SLS), ultimate limit state (ULS), and two equivalent flexural strengths were evaluated under notched flexural tests and analysed using statistical approaches. Concrete Damage Plasticity (CDP) has been employed for the analysis behaviour of developed mortars under different loadings. Additionally, an element deletion approach was used to evaluate the fracture of UHPSCM under compression and flexural loadings. The experimental results showed that adding 1% and 3% of RSF resulted in decreasing workability by 3% and 22%, respectively. Improving compressive strength by 16% and 22% and flexural by 7% and 8% were noticed in the case of samples with 1% and 3% fiber, respectively, in 28 days. In spite of the significant improvement of post-cracking behaviour of samples with 3% of RSF, this behaviour was insignificant for the samples with 1% of RSF. However, with less amount of fibre inclusion, brittle failure can be altered to ductile failure. Moreover, the behaviour of the tested specimens under different loadings was successfully predicted using Finite Element (FE) simulations.]]>

Abstrakt: Constant dentistry development causes a need for modern biomaterials with advanced properties. Commonly used titanium-based implants although characterized by satisfying durability, biocompatibility and bioinertness do not meet all the requirements for novel medical devices. Nowadays, the most attractive implants must meet such requirements as biocompatibility, bioactivity and susceptibility to biodegradation which are unobtainable for these Ti-derived ones, thus magnesium biomaterials are considered as the metallic medical devices of latest generation. However, unmodified Mg implants undergo uncontrolled biocorrosion and may mismatch with bone tissue formation. Therefore, development of Mg-based biomaterials of controlled properties is a priority. Anodic modification is a promising technique for metallic materials modification to increase their biological responses and applicability in biomedical areas. In this paper, a successful modification of Mg implants has been carried out via high-voltage anodization process resulting in the preparation of novel biomaterials with interesting properties and high potential in dental applications. Superficial oxidation was confirmed by XRD and XRF analyses. Surface morphology was investigated by SEM microscopy proving suitable for cells adhesion microstructure. In vitro incubation study showed that the biomaterials promote apatites’ formation due to highly porous morphology and locally increased pH enhancing biomineralization via calcium and phosphates ions migration, adsorption and crystallization. Biodegradation tests proved increased resistance to hydrolysis in simulated body fluids due to the surface passivation. Further investigation on biocorrosion revealed improved tolerance to human body conditions. Finally, cell culture study carried out on L929 mouse fibroblasts confirmed superior to native magnesium biocompatibility showing a high potential of newly developed implants in the field of dentistry.]]>

Abstrakt: The paper discusses contemporary city blocks and hybrid housing whose uniqueness may predestine them as present-day architectural avant-garde. The research analyses selected iconic examples of multifamily architecture whose experimental approach to shaping form and communal spaces may indicate their avant-garde character. The temporal scope covers buildings constructed after 2000. The territorial scope focuses on the area of Western culture in the broadest sense (Europe, USA). The examples described here have a distinctive and original spatial idea to show the main directions of transformation and introduce typologically new, often one-off, solutions with a prototypical design approach. Thanks to contemporary engineering, technological and material possibilities, even the boldest visions can find grounds to realise works that go beyond the usual patterns, offering a pretext to consider them avant-garde. The research findings indicate significant features that should shape the present-day architectural work that aspires to be avant-garde. ]]>

rodzaj: rozdział/fragment książki
Abstrakt: The paper presents the possibility of producing foamed geopolymer materials with various foaming agents. Geopolymer is an amorphous aluminosilicate polymer made from the synthesis of silicon (Si) and aluminum (Al), geologically obtained from minerals. Geopolymers contain long chains (copolymers) of aluminum–silicon and aluminum, stabilizing metal cations, most often sodium, potassium, lithium or calcium, and bound water, in addition, there are usually various mixed phases: silicon oxide, unreacted aluminosilicate substrate, and—sometimes—crystallized aluminosilicates of the type zeolite. Most methods of geopolymer synthesis come down to one process: The fine and dried pozzolanic materials are mixed with an aqueous solution of a suitable silicate with the addition of a strong base—usually concentrated sodium or potassium hydroxide. The resulting paste behaves like cement. Fly ash from the Heat and Power Plant in Skawina (Poland) was used as a precursor for the production of geopolymer. The activation process was performed with a 10-molar solution of sodium hydroxide NaOH in combination with a solution of sodium silicate. The foaming agents were perhydrol, aluminum powder, and the Sika® Lightcrete-400 foaming saucer—an organic surfactant for the production of low-emission, lightweight, porous concrete. The produced foamed geopolymer materials were subjected to strength and thermal conductivity tests. The properties of the foams are related to the used foaming agent, but it is not the only factor affecting the quality of the materials. In the production of samples, the crucial factors are mixing the materials, the amount of the added additive, and the temperature of the geopolymerization process.]]>

Abstrakt: Chitosan, a natural biopolymer, is an ideal candidate to prepare biomaterials capable of preventing microbial infections due to its antibacterial properties. Electrospinning is a versatile method ideally suited to process biopolymers with minimal impact on their physicochemical properties. However, fabrication parameters and post-processing routine can affect biological activity and, therefore, must be well adjusted. In this study, nanofibrous membranes were prepared using trifluoroacetic acid and dichloromethane and evaluated for physiochemical and antimicrobial properties. The use of such biomaterials as potential antibacterial agents was extensively studied in vitro using Staphylococcus aureus and Escherichia coli as test organisms. The antibacterial assay showed inhibition of bacterial growth and eradication of the planktonic cells of both E. coli and S. aureus in the liquid medium for up to 6 hrs. The quantitative assay showed a significant reduction in bacteria cell viability by nanofibers depending on the method of fabrication. The antibacterial properties of these biomaterials can be attributed to the structural modifications provided by co-solvent formulation and application of post-treatment procedure. Consequently, the proposed antimicrobial surface modification method is a promising technique to prepare biomaterials designed to induce antimicrobial resistance via antiadhesive capability and the biocide-releasing mechanism.]]>

rodzaj: materiały konferencyjne w książce
Abstrakt: Infill structures consisting of reinforce concrete (RC) frame and masonry infill walls are very popular structures, especially in seismic areas. In such structures, RC skeleton plays load-bearing role and infill walls play significant role as secondary elements stiffening the entire building during earthquakes, when they are in good shape and structural condition. Their damages lead to reducing of stiffness and thus to reducing of seismic resistance of RC frame structures with infills. They should also be resistant to cyclically repeating earthquakes to reduce economic losses. In this paper, innovative solutions protecting infill structures are presented with results of their examination on a shake table, and especially damage and stiffness parameters changing with repeating seismic excitations are discussed. Their analysis confirmed that these introduced anti-seismic solutions based on flexible bonding are able to protect infill structures against serious damage and failure (in-plane or out-of-plane) and protect RC columns against damages under repeating strong seismic action, assuring safe level of load bearing capacity. Obtained results indicate that these antiseismic solutions can be used efficiently in damaged or newly constructed infill structures in seismic areas.]]>
<![CDATA[Seismic performance of the polymer flexible joints in rc frames with various infill wall aspect ratios]]> Mon, 21 Nov 2022 09:18:32 +0100 Akyildiz, A. Tugrul; Kwiecień, Arkadiusz
rodzaj: materiały konferencyjne w książce
Abstrakt: Earthquakes affect buildings in variety of ways. Among those, infill wall failures constitute a high proportion of the total visible damages in multi-story constructions, which can be easily observed even under low or moderate intensity earthquakes. The failures occur as a result of the interaction forces emerging at the interfaces of surrounding frame and walls, and mainly attributed to the brittle intrinsic characteristics of the materials. In order to overcome this challenge, an innovative solution aiming to mitigate damages on the structural components of the infilled RC buildings from the hazardous effects of seismic motions is investigated. The solution proposes to use a material called Polyurethane PM as the flexible joint between different structural members i.e., infill walls and concrete frames, in reinforcedconcrete (RC) buildings. The material has high ductility features that allow deformability capacity to reach remarkable levels. Thus, earthquake induced lateral displacement demands on the structural systems can be satisfied by means of dissipating the seismic energy up to the high drift levels, which is a crucial point from the earthquake engineering perspective. In this study, performance of the aforementioned PolyUrethane Flexible Joint (PUFJ) is examined in single-bay and single-story RC frames with different width-height infill wall aspect ratios. Three dimensional models are created numerically in the finite elements method (FEM) environment and gradually increasing monotonic horizontal loads are imposed on the top-beam level of the frames. For the comparison purposes, Stiff (STF) type of frames are also created which represent the traditional mortar joint implementation between the frame and infill walls. Moreover, as a reference, analyses on the BareFrame (BF) systems are conducted, too. The results are evaluated in terms of the stiffness and strength status of the frames as a whole system and besides, performances of the different materials are discussed on the individual component level.]]>

rodzaj: materiały konferencyjne w książce
Abstrakt: The study presents innovative anti-seismic protection systems using PolyUrethane Flexible Joints (PUFJ) at the frame-infill interface and bonding of glass fiber meshes to the weak masonry substrate to form Fiber Reinforced PU (FRPU) as an emergency repair intervention. Due to the possibility of using the systems in existing and newly built structures in areas of increased risk of seismic excitations, the authors made an attempt to define the life cycle scenarios of these systems in terms of the possibility of extending the service life of these structures. The definition of the construction life cycle scenarios and the estimation of the corresponding investment costs and costs related to the operation and decommissioning of a given system were based on the approach presented in the ISO 15686 standard package "Buildings and constructed assets", part 2 – Service life prediction procedures and part 5 – Life cycle costing. The simulations covered a total of five variants of the systems application: (i) prefabricated PUFJ at 4 interfaces (in newly constructed buildings), (ii) injected PUFJ at 3 interfaces (improvement of existing buildings) and application of FRPU as a quick emergency or strengthening system (for buildings damaged by earthquakes) in variants (iii) at infill diagonals, (iv) at infill edges, and (v) as combination of the systems presented above (according to requirements). The cost analysis also took into account the potential impact of changes in the value of money over time and an increase in the production costs of building materials.]]>

Abstrakt: The analysis of the KMA (Krakow Metropolitan Area) area was carried out with respect to the available transport means and services. All types of the transport means (public, private, motorized, non-motorized) were taken into account as well as services allowing to plan the trip. Then the survey questionnaire on travel behavior, the use of innovative services and readiness to use the MaaS was carried out among inhabitants of the area. Basing on the analysis and the survey results the assumptions on the implementation of MaaS in KMA were proposed. Elaborated assumptions to implementing MaaS in KMA area relate, inter alia, to the functioning basis of the service, means of transportation to which it should apply as well as additional services and payment systems (packages and "pay-per-use" method). The entity responsible for establishing the service as well as stakeholders of this process were pointed out. All assumptions were made according to the paradigm of the sustainable mobility. The developed assumptions to implementing Mobility as a Service can be used by the public and private entities to establish the service in urban areas. The procedure applied in the research, due to the generally available methods and information, is universal and may be applied to similar analyses for other areas.]]>

Abstrakt: W artykule opisano rezultaty badań architektonicznych i konserwatorskich wykonanych w związku z organizacją muzeum i biblioteki w klasztorze w Mogile. Odkryto m.in. nieznaną polichromię Stanisława Samostrzelnika. Malowidło przedstawiające Chrystusa jako Salvator Mundi umieszczono na podłuczu gotyckiego okna na parterze przeoratu, w którym umieszczono bibliotekę. Pozostałe elementy wystroju włączono do ekspozycji i udostępniono zwiedzającym. Porównanie odkrytej polichromii z pozostałymi malaturami Samostrzelnika w Mogile pozwoliło na hipotezę dotyczącą ich programu ikonograficznego, który wpisuje się w etos cysterskiego życia zakonnego i może stanowić element tożsamości muzeum. Klasztorna sceneria tworzy tło dla ekspozycji, która w ciszy i skupieniu prowadzi przez historię duchowego i artystycznego rozwoju zakonu cystersów.

rodzaj: artykuł w czasopiśmie
Abstrakt: The paper presents the reconstruction of the vault in the tower of the Basilica of the Assumption of the Blessed Virgin Mary in Gdańsk. The issue was discussed in the context of research on the geometry of Gothic vaults. The research problem was to determine the spatial structure of the vault on the basis of small remnants and in the absence of unambiguous documentation. Historical and bibliographic sources as well as the technical documentation were analyzed. On this basis, several models of virtual vaults with various geometries were developed. Theoretical models were compared with the remnants of the vault (presented in the form of laser scanning documentation) to find the best solution. This allowed to confirm the validity of the approach based on strict reference to traces as opposed to prioritising idealised theoretical models. Moreover, the research on the geometry of Gothic vaults presented in this paper shows the necessity of continuous studies in this field, which may be used in conservation works.]]>

Abstrakt: Hydroxyapatite (HAp) constitutes a significant inorganic compound which due to its osteoinductivity, osteoconductivity as well as the ability to promote bone growth and regeneration is widely applied in development of biomaterials designed for bone tissue engineering. In this work, various synthesis methodologies of HAp based on the wet precipitation technique were applied, and the impact of pH of the reaction mixture, the concentration of individual reagents as well as the type of stirring applied (mechanical/magnetic) on the properties of final powders was discussed. Spectroscopic methods (Fourier transform infrared, Raman) and X-ray diffraction allowed to verify the synthesis parameters leading to obtaining calcium phosphate with 96% HAp in phase which indicated higher homogeneity of obtained powder (93.4%) than commercial HAp. Powders' morphology was evaluated using microscopic techniques while specific surface area was determined via Brunauer–Emmett– Teller analysis. Particle size distribution, porosity of powders, and stability of HAp suspensions were also characterized. It was proved that synthesis at pH = 11.0 using mechanical stirring resulted in calcium phosphate with a high phase homogeneity and homogeneous pore size distribution (6–20 nm). Moreover, obtained HAp powder showed 71.8% more specific surface area than commercial material—that is, 110 m3/g for synthetic HAp and 64 m3/g in the case of commercial powder—which, in turn, is significant in terms of its potential application as carrier of active substances. Thus it was demonstrated that by applying appropriate conditions of HAp synthesis it is possible to obtain powder with properties enhancing its application potential for medical purposes.]]>

Abstrakt: This paper proposes an approach to the comprehensive adaptation of prefabricated panel-block buildings, many of which were built before 1989, to climate change and the requirements of people with special needs while alleviating Modernist planning deficiencies. The proposal targets panel-block technologies of Eastern Bloc countries, and its application is demonstrated based on the Polish W-70/Wk-70 system but can be applied to any other prefabricated housing. The large-scale use of such systems in Central and Eastern Europe after the Second World War, coupled with their service life being far longer than initially expected, means that they form sizeable parts of these regions’ housing stocks, which are often energy-inefficient and are hard to replace with new development. We propose a novel, structured approach to identifying buildings from this group using Geographic Information Systems (GIS), urban and social analysis, and Multi-Criteria Decision-Making support methods (MCDM) for comprehensive thermal retrofitting, combined with remodelling to address crucial deficiencies in accessibility and public space renewal. Our approach can aid in extending the utility of panel-block buildings in preparation for their eventual replacement. The model presented includes an energy audit of buildings, proposing measures to reduce their energy consumption. It is proposed to retrofit the mechanical ventilation and change the heating system to a significant share of renewable energy supply by applying the current method. This would allow the users to save up to 80% of their current energy consumption and related Greenhouse Gas emissions.]]>

Abstrakt: Starting from the definition of net zero emission as the key to understanding climate change, this short overview article shows the reader that the only way to accelerate the green revolution is not through a focus on green materials, but through a broad public-private programs of education and demonstration about the need for reinvesting in the next generation of retrofitted buildings. To this end, re-thinking the way we retrofit residential buildings is necessary. A trend towards holistic design with integrated design process (IDP) introduced a different pattern of thinking that now has been reinforced by the need to modify ventilation and indoor air flow pattern to confine SAR-coV spread in habitable space. Thus, integrated control of heating, cooling air movement and humidity and leads to a merger of new technology with building automatics and open new horizons for environmental quality management in buildings. This essay deals with renovation of new building as this is a single, most important and easiest way to reduce carbon emissions.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: The search for clouds in satellite images is a challenging subject which still attracts a lot of attention due to the amount and quality of data, which is growing at a tremendous pace, the development of satellite techniques and methods, inexpensive equipment, and automation of satellite imaging processes. This paper presents a new approach to the assessment of cloudiness based on the use of the theory of moments with invariants. The values of moments with invariants, determined on the basis of the available cloudiness maps, create a new, valuable set of data, which are the geometrical parameters of the scene representing the cloud cover. In further research, the obtained data sets will be used in machine learning methods, deep machine learning methods, etc. The method is used for different conditions, including different angular positions of the Sun and time periods. The effectiveness of the method is checked on the basis of comparing the entropy results of the input maps after subtracting clouds masked by various methods. The obtained results additionally indicate the potential of the moments method as a support for the existing methods of estimating cloudiness over the sea surface.]]>

Abstrakt: Research over several years has shown that municipal engineering is an important source of humic substance formation (HS). Effluents from municipal landfills and digested sludge, due to high concentrations of organic pollutants, including HS and inorganic pollutants, are discharged to a biological treatment plant, where their largely non-biodegradable pollutants constitute a burden on the activated sludge and generate problems related to wastewater treatment. To demonstrate that humic substances, primarily soluble acids, are the carriers of micro-pollutants, their isolation was carried out from samples taken at different municipal management sites. The following analyses were performed: elemental composition, and the content of inorganic micropollutants, including heavy metals. In addition, the sorption affinity of pure HS to selected pharmaceuticals was investigated. The sorbed pharmaceuticals were Diclofenac and Estrone. HS commonly found in municipal engineering have been shown to be carriers of inorganic and organic micropollutants, including pharmaceuticals. Based on the study data, surface water’s primary source of micropollutants is treated municipal wastewater and fulvic acids are the transfer agent. To demonstrate the locations of HS occurrence within municipal engineering and the micropollutants they carry, their isolation was carried out from samples taken at different municipal management sites. Fulvic acids were studied due to their high mobility. Extraction was carried out according to the method recommended by the International Humic Substances Society (IHSS) with the author’s modification. The following analyses were performed: elemental composition (N, C, O, and H); the content of inorganic micropollutants, including heavy metals; and the IR spectrum. In addition, the sorption affinity of pure HS to selected pharmaceuticals was investigated. The sorbed pharmaceuticals were Diclofenac and Estrone. The study confirmed the occurrence of HS in municipal landfill effluents, activated sludge, excess and digested sludge effluents, and treated wastewater. At the same time, HS commonly found in municipal engineering have been shown to be carriers of inorganic and organic micropollutants, including pharmaceuticals.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: There are many causes of heart failure, one of them being valvular heart disease. In this case, the stage and type of the disease can significantly affect the hemodynamic parameters of the left ventricle of the heart. In turn, these parameters can significantly influence the mode, type and strategy of clinical treatment. The aim of the study was to analyze and map the hydrodynamic conditions of the heart using a hybrid-digital model of the circulatory system. Methods: The tests performed using the circulatory system model allowed for the simulation of the failure of both heart’s left ventricle and a set of arteries in the systemic circulation. Furthermore, the changes in hemodynamic parameters for valvular anomalies at various heartbeats were obtained. Results: The results suggested that a higher heartbeat should be sustained in such cases of complex mitral-aortic anomalies in the clinical practice. When observing low aortic pressures, heartbeat should be increased to compensate for the valvular insufficiencies. Conclusions: Extending the already conducted research could result in constituting a wide database for clinicians who are treating the insufficiency of the left ventricle of the heart. Moreover, the information included in this paper may be used for a comparison of the clinical anomalies, which facilitates a correct diagnosis. The test-stand used in the research can be applied to predict the anomalies of the circulation system for a quick and precise analysis of a clinical anomaly of a patient without physical presence.]]>

rodzaj: artykuł w czasopiśmie
Abstrakt: Characteristics of both surface and groundwater as well as water treatment itself determine properties of sludge produced as a by-product of technological processes. However, most of the currently available literature data and research focuses rather on the evaluation of water treatment processes, comparing the quality of raw water and the quality of water after treatment. The sludge produced at the water treatment plant, presented in the research, is the most environmentally sensitive by-product of the water treatment processes, that is, volumetric and contact coagulation with the use of coagulants. The chemical composition of the produced sludge varies, depending on the raw water quality and the type and amount of chemical reagents dosed. Two types of coagulants were dosed to the system over the period (year) of sludge sampling. They were: an aqueous solution of a mixture of polyaluminium chloride and a mixture of aluminum sulphate hydroxychloride and a complex solution of aluminum hydrochloride. Therefore, it is very important for the plant operators, to accurate determine the chemical composition of the sludge, especially in terms of the presence of metals in water. In the article, the authors offered an innovative approach in order to assess contamination of a coagulation sludge with selected metals. The work summarized several years of research conducted at the water treatment plant, which obviously increased the application value of the work. The authors described the principles the water treatment processes and tried to assess their effectiveness with a qualitative analyzes of sludge generated at particular stages of water treatment. The sludge was analyzed with qualitative methods of X-ray crystallography, that is, X-ray fluorescence and X-ray diffraction. Additionally, the laboratory and technological conditions required to proceed with these methods were presented. The methods, more accurate than in conventional laboratory, allow for a better determination of the metals presence in the sludge.]]>

Abstrakt: Thermal waste treatment plants are an answer to the important problem of waste neutralization on the one hand, while inspiring various emotions in society due to their impact on their planned or existing sites on the other. The primary benefit from incinerating waste is the ability to reuse it as fuel to produce energy. The objective of the research presented in this paper was to assess the production potential of eco-incinerators and to investigate the potential impact that the operation of a thermal waste treatment plant can have on its surroundings. To this end, the study included analyses in three problem groups: urban planning, balance calculations and the numerical modeling of fouling spread. The area subjected to the analyses was a district of a model city with a plant at the center. The goal of the CFD modeling was to determine the spread of gaseous pollutants (CO, CO2, SO2, NOx) produced as a result of the incineration of municipal waste in the incineration plant, to get their approximate mass fraction values at a distance of 1 km from the smokestack outlet. The spread of gaseous pollutants in CFD modeling was simulated using the k-epsilon RNG model. It is noticeable that the largest mass fraction of the given gases has carbon dioxide, which is also characterized as a 1.5 times heavier gas than the air. The paper also presents thermal calculations that present the performance of the entire thermal waste treatment plant, which depends on the final use of the energy it produces.]]>

As-prepared WP@NC nanocomposites revealed enhanced electrocatalytic hydrogen evolution reaction (HER) activities in both of acidic and alkaline electrolytes with Tafel slopes of 73 and 85 mv/dec, respectively. Furthermore, WP@NC nanocomposites instead of noble metal co-catalysts were loaded on superior thin g-C3N4 nanosheets (CN) by thermal polymerization at different temperature. In the case of without Pt, the photocatalytic hydrogen generation rate of CN/WP@NC heterojunctions prepared using optimized conditions reached 1217.6 μmol g−1 h−1, which was ∼196 folds of pure g-C3N4 nanosheets. This is ascribed to that N-doped carbon layers on WP improved the separation and transfer efficiency of photogenerated charge carriers. Interestingly, the carbon layers improved the chemical stability and corrosion resistance to ensure enhanced photocatalytic hydrogen generation in simulated seawater. In addition, the sample revealed outstanding light-assisted elimination capability of 4-nitrophenol (4-NP) because of the selective hydrogenation reaction to 4-aminophenol and photodegradation reaction of 4-NP. Under visible light irradiation, the removal efficiency using CN/WP@NC reached 99% within 10 min. The kinetic constant (0.443 min−1) was 17.8 times of that of g-C3N4 nanosheets. This work supplied an efficient method to fabricate bi-functional noble-metal-free catalyst towards clean energy production and environment remediation.]]>
