Abstract

Changing a problem’s representation is a crucial process when solving insight problems. Recently, Laukkonen and Tangen (2017) found that observing ambiguous figures such as a Necker Cube before solving problems can increase insight frequency. In our research, we extended their procedure by including measures of feelings of insight (e.g., confidence and pleasure). This approach allowed us to test the replicability of relationships between perceptual switching and insight frequency in terms of both accuracy of problem solutions and insight phenomenology. The research took the form of two studies using two different samples (NA = 68 and NB = 198) using online platforms. Our results consistently showed no effect of prior Necker cube perception on accuracy. However, we found a significant difference in self- reported insight (1 - non-aha! experience to 5 – a very strong aha! experience) in our Sample B study. The results suggest the possibility that viewing ambiguous figures may not have a triggering effect on insight problem-solving performance but that it may trigger stronger insight experiences when solving insight problems.

Abstract

The aim of the present study is to investigate the relationship between explicitation and directionality in simultaneous interpreting. Given that explicitation in this mode of interpretation is often triggered by the constraints inherent in the process of interpreting, it has been hypothesized that explicitating shifts might be more frequent in retour, which is considered to be more demanding. The study is both product- and process-oriented, relying on recordings and transcripts of interpreting outputs as well as retrospective protocols. The participants in the study were 36 advanced interpreting students. The analysed forms of explicitation range from cohesive explicitation (e.g. adding connectives, reiteration, etc.), through substituting nominalisations with verb phrases and disambiguating lexical metaphors, to inserting explanatory remarks. The present paper is aimed to be a pilot study for a larger project in progress.

Abstract

The aim of the study study was to model, with the use of a neural network algorithm, the significance of a variety of factors influencing the development of hearing loss among industry workers. The workers were categorized into three groups, according to the A-weighted equivalent sound pressure level of noise exposure: Group 1 (LAeq < 70 dB), Group 2 (LAeq 70–80 dB), and Group 3 (LAeq > 85 dB). The results obtained for Group 1 indicate that the hearing thresholds at the frequencies of 8 kHz and 1 kHz had the maximum effect on the development of hearing loss. In Group 2, the factors with maximum weight were the hearing threshold at 4 kHz and the worker’s age. In Group 3, maximum weight was found for the factors of hearing threshold at a frequency of 4 kHz and duration of work experience. The article also reports the results of hearing loss modeling on combined data from the three groups. The study shows that neural data mining classification algorithms can be an effective tool for the identification of hearing hazards and greatly help in designing and conducting hearing conservation programs in the industry.

Abstract

The impact of the noise radiated from merchant ships on marine life has become an active area of research. In this paper, a methodology integrating observation at a single location and modelling the whole noise field in shallow waters is presented. Specifically, underwater radiated noise data of opportunistic merchant ships in the waters of Zhoushan Archipelago were collected at least one day in each month from January 2015 to November 2016. The noise data were analyzed and a modified empirical spectral source level (SSL) model of merchant ships was proposed inspired by the RANDI-3 model (Research Ambient Noise Directionality) methodology. Then combining the modified model with the realistic geoacoustic parameters and AIS data of observed merchant ships, the noise mappings in this area were performed with N×2D of Normal Mode calculations, in which the SSL of each ship was estimated using the modified model. The sound propagation at different receiving positions is different due to the shielding effect of islands and bottom topography. The methodology proposed in this paper may provide a reference for modelling shipping noise in shallow waters with islands and reefs.

Abstract

Luffa cylindrica M. Roem, is commonly called sponge gourd or Egyptian cucumber. In September 2018, several plants showing symptoms of powdery mildew were observed in some fields at different locations in Egypt. Identification and pathogenicity tests indicated that the causal fungus of powdery mildew disease of luffa cylindrica was Podosphaera xanthii. Results of surveyed luffa plants grown at different field localities of northern Egypt, for powdery mildew disease incidence revealed that the maximum record (57.33%) of disease occurrence was recorded in some fields belonging to Beheira governorate followed by, Alexandria and Sharqia (53.67% and 48.00%, respectively). Meanwhile, fewer occurrences were observed in Kafer El-Sheekh governorate (45.33%). We applied biocontrol agents as a foliar spray against powdery mildew in vitro and under field conditions. The effects of some essential oils, organic acid and bioproducts were also studied. All treatments significantly reduced P. xanthii compared to untreated plants. Chaetomium globosum and Saccharomyces cerevisiae alone or grown on rice straw and/or bagas showed highly reduced disease incidence compared to the other treatment. From the present study it could be suggested that the usage of biocontrol formulated on rice straw might be used as an easily applied, safe and cost effective control method against powdery mildew diseases.

Abstract

This paper attempts to find out what is the role of competitive environment in shaping the sensitivity of growth in banking to the business cycle. To answer this question, we apply a large set of individual bank level data including over 8000 banks operating in more than 100 countries. This study uses the growth of assets, loans, deposits and leverage as proxies of bank growth and Lerner index as a proxy for the competitive environment. The analysis shows that decreased competition is associated with increased procyclicality of bank growth. However, in a perfectly competitive environment the growth turns out to be countercyclical. This effect differs between high- and lowincome countries. A perfectly competitive environment is associated with countercyclical growth in high-income countries. The opposite result is found for low-income countries. Our results for Central Eastern European countries show that increased competition is associated with enhanced procyclicality of growth.

Abstract

Magnesium aluminate spinel (MgAl2O4) is an important refractory material of magnesia origin. It is formed by the reaction of magnesium and aluminum oxides. In this study, TiO2 was added to magnesite waste and alumina (Al2O3) powders in different proportions and the mixtures were sintered at different temperatures after shaping. The aim of this study was to produce spinel economically by recycling waste materials. Therefore, titanium dioxide (TiO2) added magnesium aluminate spinel was produced and the products obtained were characterized by XRD and SEM-EDS analyses. In addition, bulk density, apparent porosity and microhardness values were measured and the effects of TiO2 additive on magnesium aluminate properties were examined. The better values were determined in samples doped 4 wt.% TiO2 at the sintering temperature of 1400°C.

Abstract

Recently, transition metal oxides, which exhibit favorable catalytic abilities, have also been investigated as a material for the detection of hydrazine (N2H4). It has been reported that mixed metal oxides usually offer a higher electrochemical activity than binary oxides. In this work, a TiO2–Fe2O3 coupled system is presented as an enhanced material with major applications in electrochemical detectors. The electrochemical behavior of glassy carbon electrodes modified with TiO2–Fe2O3 in the absence and presence of hydrazine was evaluated via cyclic voltammetry (CV). Experimental results also suggest that the formation of the TiO2– Fe2O3 coupled system enhances electrochemical catalytic performance in N2H4 detection. The modification TiO2 + 2 mol% Fe2O3 provides good analytical performance of detection (0.13 mM) and quantification limits (0.39 mM). The presented coupled system provides the premise for a suitable material for a stable and sensitive N2H4 sensor.

Abstract

Desmopathy of the collateral ligaments of the equine interphalangeal joint is caused by a combination of factors, including hoof shape, excessive loading and ground surface. This complex problem poses a diagnostic challenge due to the non-specificity of perineural analgesia and the limitations associated with the most popular imaging methods such as radiography and ultrasonography. The aim of this study was to retrospectively determine the prevalence of desmopathy of the collateral ligaments of the equine distal interphalangeal joint in Poland between 2016 and 2019, and to establish the frequency and type of the associated pathologies. Desmopathy of the collateral ligaments of the distal interphalangeal joint was diagnosed in 14% of 152 horses examined by magnetic resonance imaging (MRI). In 64% of the cases, other changes were observed in the equine digit, and in 36% of the cases, desmopathy was the only diagnosed problem. Desmopathy of the collateral ligaments is not a frequently reported pathology in the distal part of the equine limb. The diagnostic difficulties described in this article suggest that considerable caution should be exercised when formulating the final diagnosis, prognosis and treatment options.

Abstract

This is the first study to identify 23 protein spots corresponding to 13 proteins in mitochondria isolated from rabbit epididymal spermatozoa. In the group of protein spots identified in stress-induced samples, the abundance of 20 protein spots increased, whereas the abundance of three protein spots (GSTM3, CUNH9orf172, ODF1) decreased relative to the control. The results of this study provide valuable inputs for future research into the molecular mechanisms implicated in pathological processes during oxidative stress (OS).

Abstract

Morphometric attributes of 705 stromatoporoid specimens from a number of exposures from the Silurian of Podolia (Ukraine) and the Devonian of the Holy Cross Mountains (Poland), representing a wide array of shallow water carbonate sedimentary environments, have been analysed. Taken into account were such parameters as: general shape of the skeleton, shape of the final growth form (living surface profile), upper surface character, latilaminae arrangement, burial ratio and type of initial surface. A number of new ratios has been introduced, designed mainly to improve the mapping of the outlines of the stromatoporoids upper surfaces. All studied specimens were treated as belonging to one group, and relations between particular attributes were tested. The results were analysed in terms of potential environmental factors influencing stromatoporoid morphometric features. Most of the distinguished attributes are common in the studied group and occur in various combinations, with an important exception of parameters designed to reflect the shape of the skeleton’s upper surface, which are distinctly predominated by convex variants. This indicates that surface concavity was a highly undesired feature among stromatoporoids. Upper surface convexity is interpreted herein as a response to the hazard of clogging of the animals pores by tiny sediment particles suspended in the bottom turbid water layer. Common low burial ratios of final living surface profiles and the occurrence of specimens with a smooth upper surface but a non-enveloping latilaminae arrangement are other reflections of this phenomenon. Burial by sediments and redeposition were also important factors governing stromatoporoid development. No direct arguments indicating photosensitivity of stromatoporoids can be deduced from the presented results. The hitherto postulated allometric tendency among stromatoporoids of starting growth as laminar forms and later adopting consecutively higher profile shapes has not been confirmed here. On the contrary, a tendency for gradual elimination of very high profile forms with increasing stromatoporoid size has been observed. The final shape of a stromatoporoid skeleton was always an effect of a combination of various agents.

Abstract

The article presents the results of research concerning the effect of anthracite dust with 10%, 20%, 30%, 40% and 50% content in composites with a polypropylene matrix on selected properties. Hardness was examined with the Shore’s D method; stiffness, tensile strength as well as (MFR) Melt Flow Rate and (MVR) Melt Volume Rate of the investigated material were evaluated; wettability of the obtained material was also determined. Surface and volume resistivity were also investigated; the thermal properties of the filler were determined by thermogravimetric analysis (TGA). It was found that the investigated polypropylene composites filled with anthracite dust are hydrophobic materials and the composite hardness and stiffness are growing along with the volumetric increase of anthracite. It was noted that anthracite reinforces the material to a limited extent.

Abstract

The main aim of the study is an assessment of models suitability for steel beams made of thin-walled cold-formed sigma profiles with respect to different numerical descriptions used in buckling analysis. The analyses are carried out for the sigma profile beam with the height of 140 mm and the span of 2.20 m. The Finite Element (FE) numerical models are developed in the Abaqus program. The boundary conditions are introduced in the formof the so-called fork support with the use of displacement limitations. The beams are discretized using S4R shell finite elements with S4R linear and S8R quadratic shape functions. Local and global instability behaviour is investigated using linear buckling analysis and the models are verified by the comparison with theoretical critical bending moment obtained from the analytical formulae based on the Vlasow beam theory of the thin-walled elements. In addition, the engineering analysis of buckling is carried out for a simple shell (plate) model of the separated cross-section flange wall using the Boundary Element Method (BEM). Special attention was paid to critical bending moment calculated on the basis of the Vlasov beam theory, which does not take into account the loss of local stability or contour deformation. Numerical shell FE models are investigated, which enable a multimodal buckling analysis taking into account interactive buckling. The eigenvalues and shape of first three buckling modes for selected numerical models are calculated but the values of critical bending moments are identified basing on the eigenvalue obtained for the first buckling mode.

Abstract

The article sets the signposts of a theft in history, as it charters the way the discipline of Philosophy has been narrated as a ‘western’ system of thought. We follow the global sources of Philosophy and establish how better knowledge and education can develop, once the myths of the past are overcome.

Abstract

Approximately 30 million tons of tailings are being stored each year at the KGHMs Zelazny Most Tailings Storage Facility (TSF). Covering an area of almost 1.6 thousand hectares, and being surrounded by dams of a total length of 14 km and height of over 70 m in some areas, makes it the largest reservoir of post-flotation tailings in Europe and the second-largest in the world. With approximately 2900 monitoring instruments and measuring points surrounding the facility, Zelazny Most is a subject of round-the-clock monitoring, which for safety and economic reasons is crucial not only for the immediate surroundings of the facility but for the entire region. The monitoring network can be divided into four main groups: (a) geotechnical, consisting mostly of inclinometers and VW pore pressure transducers, (b) hydrological with piezometers and water level gauges, (c) geodetic survey with laser and GPS measurements, as well as surface and in-depth benchmarks, (d) seismic network, consisting primarily of accelerometer stations. Separately a variety of different chemical analyses are conducted, in parallel with spigotting processes and relief wells monitorin. This leads to a large amount of data that is difficult to analyze with conventional methods. In this article, we discuss a machine learning-driven approach which should improve the quality of the monitoring and maintenance of such facilities. Overview of the main algorithms developed to determine the stability parameters or classification of tailings are presented. The concepts described in this article will be further developed in the IlluMINEation project (H2020).

Abstract

Currently, the possibilities offered by measurement techniques allow development of both cities in the form of 3D models as well as models of small and large architecture objects. Depending on the needs, the scale of an examined object or the intended use of the final product, geodesy finds readymade measurement methods. If one wants to work out a 3D model of a building object in detail, the most accurate way is to use laser scanning technology. However, there are situations in which limitations resulting from the terrain layout or the structure of the building preclude to obtain full information about its shape. In such situations, the solution is to integrate data from various measurement devices. If creating a full 3D model of large buildings, the best choice to complete data, especially the roof of the object, is to use an unmanned aerial platform, because the resolution of images made on a low altitude is good enough to obtain a satisfactory effect in the form of a point cloud. The research used integration of data obtained at low altitude from two unmanned aerial vehicles, Fly-Tech DJI S1000 and DJI Phantom 3 Advanced – using various types of missions – with data recorded with the Leica ScanStation P40 terrestrial laser scanner. The data was integrated by giving them a common coordinate system – in this case the 2000 system, for the grid points measured in the field with the GNSS technique, and the use of Cyclone, Metashape and Pix4D software for this purpose. Combined point clouds were used for 3D modelling of the sacred object with Bentley CAD software. The accuracy with which data integration was performed and errors resulting from the use of various measurement techniques were determined. The result of the study is a 3D model of the Church of Our Lady of Consolation, located in Krakow at the Sportowe estate.

Abstract

The paper discusses an occurrence or latent reactions in the direction perpendicular to the movement of the suspension systems in vibratory machines supported by parallel leaf springs. These reactions occur despite an apparent lack of any forces acting in that direction and may - for long machine bodies - reach values comparable with the exciting force of the vibrator. Analytical relationships allowing for estimation of the value of reactions were derived. The obtained results were verified by means of the Geometric Element Method as well as by the performed experiments.

Abstract

This paper presents the unique value of Kengo Kuma’s idea of rooted architecture that results from an innovative approach to the environment. This idea could be the basis for a new paradigm of an architecture befitting of our times, in which the natural environment is degraded. The study was based on an analysis of texts by and on Kuma, supported by references to a selection of his projects. The features of rooted architecture in Kuma’s idea as well as the organicity of rooted architecture, its presentation in Japanese and Western tradition and its radical nature are discussed. The results of this study are: an indication of the link between rooted and organic architecture in Kuma’s original approach, the unique value of the idea of rooted architecture as a new approach to the environment, and the presentation of this idea as a design method based on an interrelation between a place and the human body.

Abstract

To reduce the recoil and improve the stability of small arms, a muzzle brake compensator is attached to the muzzle of the barrel. This device uses the kinetic energy of the powder gas escaping from the bore after the bullet is fired. In this paper, the authors present the determination of the thermo-gas-dynamic model of the operation of a muzzle brake compensator and an example of calculating this type of muzzle device for the AK assault rifle using 7.62x39 mm ammunition. The results of the calculation allowed for obtaining the parameters of the powder gas flow in the process of flowing out of the muzzle device, as well as the change in the momentum of the powder gas's impact on the muzzle device. The model proposed in the article provides the basis for a quantitative evaluation of the effectiveness of using the muzzle device in stabilizing infantry weapons when firing.

Abstract

The paper investigates and analysis sacred eye-catchers in Transylvanian gardens and parks. Interpretation of visual connections defined by landscape features with a sacred meaning (crypts, chapels, crosses, thumbs etc.) are the present study’s main purpose. The analysis of the visual connections on a landscape scale comprises the examination of outstanding visual elements (eye-catchers) that are decisive in the case of historic landscapes, gardens and parks, and among these in the case of castle gardens, manor houses and demesnes as well. In these cases the relationship between a manor garden and the surrounding landscape is the result of a conscious shaping of the environment. The sights which determine forcefully the historicity of the landscape are the results of enduring cultural influences over time. Although only just a very few of these former landscape connections persist, their preservation represents a public interest. The investigated eye-catchers – as outstanding landscape elements – determine in a decisive way the structure of garden landscapes in Transylvania. The sentimental, then romantic trends prevailing in the 19th century in many cases expected that outstanding buildings also become important parts of the gardens. The study proves the landscape compositional role and importance of the sacred features situated within the manor gardens, or outside the gardens, in the surrounding landscape, representing a visual entity with the castle garden ensemble.
