Xylitol is an important product of xylan valorization — the main hemicellulose of birch and aspen wood. Xylitol is obtained by direct hydrogenation of xylose. In present study, the xylose was obtained by acid hydrolysis of birch wood xylan. The industrial catalyst for the xylitol production process is Raney nickel. Pyrophoricity, tendency to sintering, Ni leaching and contamination of the product are actual problems of its use. We have developed new supported ruthenium catalysts based on mesoporous silicate SBA-15 doped with zirconia. The proposed method of modification of SBA-15 by doping with zirconia improves the hydrothermal stability. The deposited Ru is present in the form of highly dispersed RuO2 particles and is distributed evenly. The catalysts are stable, safe and environmentally friendly. Their high catalytic activity allows the process to be carried out in very mild conditions – in pure water at 70 °C and a pressure of 5.5 MPa H2. While the catalysts provide 96-99% selectivity for xylitol. The introduction of the developed catalysts into the xylitol production might reduce the product purification cost of and the process energy consumption, thereby improving ecological and economic indicators of deep chemical processing of plant raw materials.
Decision support based on performance data using the analytic hierarchy process without expert judgement
Authors: Gavião Luiz Octávio , Lima Gilson Brito Alves , Garcia Pauli Adriano de Almada , Teixeira Leandro da Silva
Published: January 2024

Goal: This article proposes a decision model based on the Analytic Hierarchy Process that allows carrying out the evaluation of alternatives in a multicriteria problem, without expert judgement.
Design / Methodology / Approach: The algorithm is based on AHP. The novelty is the transformation of a performance data matrix into pairwise evaluation matrices, instead of using experts’ judgement.
Results: The algorithm was applied in a defense procurement problem for the choice of a light 4x4 vehicle for amphibious operations. The results allowed ranking the 17 models based on catalog data.
Limitations of the investigation: the algorithm depends on the availability of catalog data, not always available in open sources in the defense industry.
Practical implications: Decision support involves several activities in Operations Management and AHP has been frequently applied to solve problems in this sector. The proposed algorithm allows performing deterministic or probabilistic evaluations, depending on the degree of uncertainty and precision involving the systems’ performance data. These assessments are composed of scenarios to facilitate decision making.
Originality / Value: AHP typically uses experts for pairwise judgments. However, human judgment is subject to outcomes that involve bias and cognitive distortions. Few studies have modeled the AHP without experts, even so they used human judgment in some part of the process. The approach proposed here does not require human judgment and returns two different results, based on the database precision. This new approach gives decision makers a different perspective and can alter the final choice.
Development of software for information-measuring Systems for frequency analysis of binary-quantized Signals
Authors: Mashkov Andrey V.
Published: January 2024

The article discusses the methodology and design template for a complex of structurally, functionally, informationally and metrologically compatible software modules that implement algorithms for calculating estimates of the PSD power spectral density based on binary-signed analog-stochastic quantization with reduced multiplicative complexity. Algorithmic support makes it possible to calculate PSD estimates by the method of averaged modified periodograms and by the correlogram method using time correlation windows based on a discrete-event representation of the results of binary-sign analog-stochastic quantization. This approach made it possible to perform integration operations analytically, which eliminates the methodological error caused by performing these operations in digital form. In addition, the multiplication operations degenerate into procedures that basically require the execution of logical operations and simple arithmetic operations of summing and subtracting the values of the correlation windows, which significantly reduces the complexity of estimating the PSD.

Published: January 2024

The paper considers the problem of a microgrid output inverter selecting, when information about operating conditions is uncertain. The following factors are considered as sources of uncertainty in information about operating conditions: the possibility of the load increasing in the area, for which the microgrid is being designed, the prospects for its integration into the local power supply system, based on the microgrid, operating in the given region, as well as possible changes in the element base due to import substitution.

A system of criteria and a methodology for optimal selection have been developed, based on a combination of multi-vector optimization approaches and the hierarchy analysis method. The quality criterion of generated energy, the criterion of reliable operation in conditions of information uncertainty and the criterion of economic indicators were cho- sen as vector criteria. The total number of scalar criteria that are components of the specified vector criteria is seven. At the first stage of selection, an algorithm is used for expert assessment of the importance of vector criteria and their scalar components, as well as values of these criteria for compared alternatives, using of the hierarchy analysis method. At the second stage of selection, considered inverters are ranked according to a global criterion, calculated based on results of the first stage. The technique is demon- strated by choosing between three well-known schemes of autonomous inverters: a voltage inverter with PWM-shaping of the output curve, a current inverter with a variable struc- ture and a group multilevel inverter based on a universal source of levels, when they are operating in autonomous or integrated into the system of other microgrid modes. The de- scribed selection technique can be used, when other microgrid conversion equipment de- vices are selecting.
Kodyfikacja prawa kanonicznego z 1983 roku. W 25-lecie promulgowania przez Jana Pawła II nowego Kodeksu Prawa Kanonicznego
Authors: Góralski Wojciech
Published: January 2024

The Catholic Church, while discharging – from the very beginning – its religious mission in the world, governs itself with its own legal order. Initially, but for a relatively short period of time, the Christians sought for the principles of their Christian life exclusively in the Revelation. There came however the epoch in which the guidelines for these principles were derived also from the provisions that were ever more frequently issued by the Church authorities. Since the propotion of these provisions systematically grew there appeared a natural tendency, continued throughout centuries, to compile the Church law collections. The tendency toward the inroduction of unification among the accumulating norms reached its climax in the Decretals of Gregory IX (1234). On the other hand the Corpus Iuris Canonici, composed of six original collections, and annouced by Pope Gregory XIII in 1582 was not awarded the status of official collection. It was only in the 20th century that there came to being the appropriate circumstances for the creation of the codification in the modern sense. These circumstances enabled Pope Pius X to embark upon the codification undertaking. The latter was completed by Pope Benedict XV's publication of the Code of Canon Law in 1917. In 1963, Pope John XXIII, while following the line launched by aggiornamento of Vatican Council II, initiated the revision of the Code of canon law. To reach that goal he appointed a special commission of cardinals, supported by the collegium of consultants (experts in canon law). The labour over the revision and simultaneously the codification of canon law, undertaken after the Council ended its sessions, were a long and complex process. There participated in it also the consulting agencies such as inter alia the episcopates of particular countries as well as the departments of theology and canon law of Church Universities. While preparing the new Code of canon Law, the codifiers took into consideration the recommendations and directives issued by Vatican Council II as well as the rich post-Council legislation. What however made up the major source for the discussed undertaking was the Code of Canon Law of 1917, this being the expression of faithfulness toward the canonical tradition. The codification work of Pope John XXIII was continued by Popes Paul VI and John Paul I but it was only John Paul II who managed to bring the work to an end. After almost 20 years of the codifiers' arduous labour the Polish Pope announced the new Code of canon law. This was done on the 25th of January 1983 (the Code being in effect from the 27th of November of 1983). The ceremonious presentation of the Code, made with the participation of the supreme legislator in the Church, took place on the 3rd of February of the same year.

Study on stress distribution and extrusion load threshold of compressed filled rock joints
Authors: Wang Pengpeng , Du Shigui , Li Gan , Luo Zhanyou
Published: January 2024

The distribution of stress and the normal extrusion load threshold in weak interlayer are crucial for direct shear test of filled rock joints, but there is a lack of theoretical research in this area. First, an analytical solution for stress distribution was derived using a semi-inverse method. Then, it is compared by the numerical simulation method. Finally, the influence of the width and thickness of weak interlayer on the extreme values of stress components was analyzed, and the distribution pattern of the normal extrusion load was discussed. The results show that under the same conditions, the analytical solution and the numerical simulation results are in good agreement. The maximum horizontal stress in the weak interlayer decreases with increasing width and increases with increasing thickness, while the change of the minimum is opposite. The normal extrusion load increases first and then decreases along the width direction of the weak interlayer. By comparing the normal extrusion load with the empirical value, the mechanism of extrusion failure in the weak interlayer is revealed.
Experimental study of improving hot mix asphalt reinforced with carbon fibers
Authors: Rasheed Sozan S. , Nsaif Maha H. , Abduljabbar Ahmed S.
Published: January 2024

Using hot asphalt mixtures (HMAs) is very common in flexible pavement construction due to its mechanical properties of durability, water resistance, and riding comfort. It proved to substantially reduce the applied stresses from vehicular traffic to subgrade. However, these types of pavements can undergo different types of distress such as cracks and rutting, which could be the result of weak mixing of the asphalt mixture and/or increasing traffic volumes. Therefore, the need to improve the mechanical properties of hot mix asphalt mixtures using different additives and modifiers was raised. Different materials have been recently used to reinforce asphalt concrete. For the construction of road pavements, using fibers in a HMA has emerged as a significantly more appealing option due to their strengthening properties. The alteration of asphalt binder is expected to benefit from carbon fibers (CFs) more than other types of fiber. In this study, an experimental study is carried out to investigate the effects of adding CFs to the asphalt mixtures with grades of (40–50) which comply with the Iraqi specifications. Twelve Marshall specimens were tested for stability and flow, 24 specimens for moisture failure testing, and two specimens for the rutting resistance of the asphalt mixture. The optimum bitumen content of 5.0% was used to prepare all the specimens. Different percentages of CFs by weight of asphalt (0, 0.2, 0.4, and 0.6%) were implemented to study the performance of paving mixtures. The way to mix the disperse the CFs homogeneously is by dry state (after separating the fibers manually) for 10 min, and then the asphalt was added; the mixture was heated to 165°C and mixed for at least 20 min. The results showed that the optimum properties of the HMA were reached by adding 0.4% CF to the HMA. Marshall stability was increased by 48%, the flow was decreased by 23%, and in addition, rut depth was reduced by 50%. The unit weight and the percentage of air voids in the mix were maintained and, along with other mix properties, are preserved within acceptable limits. Moreover, the indirect tensile strength has increased by 88.6%. Furthermore, moisture susceptibility reached 88%. Therefore, the addition of 0.4% CFs improved the performance of HMA at a high temperature of 60°C, which is close to the paving temperature in Iraq, by reducing the rutting of the asphalt mixture, which is considered the most dangerous tiling problem in Iraq. By improving the performance characteristics of asphalt mixture, the durability of the pavement will increase, and the riding will be more comfortable.

The aim of this study is to address the growing concern about microplastics in the ocean and their potential harm to human health through ingestion. The MPs issue is largely a result of the increasing demand for electronic devices and their components. To tackle this challenge, the research aimed to develop a green polymer electrolyte that used glycerol as a plasticizing agent to improve ionic conductivity. The polymer host included chitosan and polyvinyl alcohol and was composed of sodium acetate. To evaluate the performance of the polymer electrolyte, various analytical techniques were used, including impedance and electrochemical studies. The ionic conductivity of 7.56 × 10−5 S·cm−1 was recorded. The dielectric property study confirmed the ionic conduction process in the system and revealed the existence of non-Debye type relaxation, as indicated by asymmetric peaks of tanδ spectra. The alternating conductivity exhibits three distinguished regions. The polymer electrolyte was discovered to be electrochemically stable up to 2.33 V and capable of storing energy as a non-Faradaic electrochemical double-layer capacitor (EDLC). The cyclic voltammetry pattern is a leaf like shape. The EDLC was able to be charged and discharged up to 1 V, and it showed cyclability and could be used in low-voltage applications.
Effect of sinusoidal pulsating speed enhancement on the mixing performance of plastics machinery
Authors: Liu Tianlei , Dong Tianwen , Liu Bangxiong
Published: January 2024

Numerous vibration-assisted methods have been adopted to solve problems in polymer processing, but the introduction of vibration fields is typically done on small extruders or injectors in school laboratories and industrial research rooms, which profoundly limits the application of vibration technology. The purpose of this study is to put forward a simple vibration excitation method for all scale extruders or injection molding machines. To recover the mixing performance of that excitation method, a numerical investigation was carried out using the CFD software ANSYS POLYFLOW 19.2, and the analysis and comparison were made between the mixing performance of a simplified screw element with and without a sinusoidal pulsating speed field. The results showed that not all dynamic states with the superimposed excitation field have better mixing performance than the steady state without any pulsating field. Nevertheless, the introduction of a pulsating speed field under certain parameters setting can indeed enhance the stretching rate, reduce the separation scale, increase the mixing efficiency, and lower the screw force. These findings are of great importance and provide valuable references for the development and application of vibration-assisted molding technology in plastics machinery.

A planar graph as a topological model of a traditional fairy tale
Authors: Nazarov Nazarii
Published: January 2024

The primary objective of this study was to propose a functional discrete mathematical model for analyzing folklore fairy tales. Within this model, characters are denoted as vertices, and explicit instances of communication – both verbal and non-verbal – within the text are depicted as edges. Upon examining a corpus of Eastern Slavic fairy tales in comparison to Chukchi fairy tales, unforeseen outcomes emerged. Notably, the constructed models seem to evade establishing certain connections between characters. Consequently, instances where the interactions among fairy tale characters would result in a non-planar graph structure are notably absent. To put it differently, the models refrain from incorporating sub-graphs delineated by the Kuratowski theorem governing planar graphs, specifically the minimal non-planar graphs Κ5 and Κ3,3. Remarkably, even in more extensive texts featuring a larger cast of characters, connections that would yield a non-planar graph pattern are consistently avoided. This leads to the formulation of a hypothesis positing that traditional folk tales adhere to a “planar narrative” design – an identifiable narrative variant characterized by inherent limitations in complexity. This design, in turn, appears deeply entrenched within the societal framework of the cultures that produced these folk narratives.
Kinetics and thermodynamics of unimolecular dissociation of n-C3H7I
Authors: Bystrov Nikita , Emelianov Alexander , Eremin Alexander , Yatsenko Pavel
Published: January 2024

The present work expands previous studies on the kinetics of the n-C3H7I unimolecular decomposition and the thermodynamic properties of n-C3H7I and i-C3H7I molecules, by providing combined experimental and theoretical data on the rate constant for reaction of n-C3H7I + Ar ⇌ n-C3H7 + I + Ar, as well as thermodynamic data for iodopropane isomers, calculated based on the density functional theory. The n-C3H7I dissociation rate constant has been precisely determined in shock-tube experiments by applying atomic resonance absorption spectrometry (ARAS) at the resonance transition wavelength of atomic iodine (183.0 nm) in a temperature range from 830 to 1230 K at a pressure of 3–4 bar. The resulting expression is presented in the Arrhenius form: k
1st = 1.17 × 1013exp(−191.4 kJ mol−1/RT) (s−1). Theoretical RRKM/ME calculation of the temperature- and pressure-dependent rate constant and channel branching ratio have been based on quantum chemical calculations and were performed over a wide range of thermodynamic conditions (T = 300–2000 K, p = 10−4 to 102 bar). Additionally, the thermochemistry of the reactions of n-C3H7I dissociation and isomerization has been calculated on B3LYP/cc-pVTZ-PP level of theory. Thermodynamic data, which are provided in NASA polynomial format, are in a better agreement with the available experimental data and previous theoretical estimates.

Empowerment and the quality of superior-subordinate relationships in the international business environment
Authors:   Poznań University of Economics and Business, Poland, Stefańska Magdalena , Grabowski Gabriel ,   Poznań University of Economics and Business, Poland
Published: January 2024

The aim of this paper is to identify and explore nature of superior-subordinate relationship and the different uses of empowerment in organizations where employees and managers are of different nationalities. The hypothesis formulated in the study was that a correct relationship fosters empowerment, but this is conditioned by whether or not the work environment is an international one. The research was conducted using the CAWI technique on a non-randomly selected sample of 277 respondents, and confirms a positive correlation between empowerment and the quality of relationships, and also between empowerment and the type of relationship. Moreover, the perception of relationships is modified when an international working environment is considered. In all models, the formal relationship proves to be an irrelevant factor in the use of empowerment. As far as the origin of the superior is concerned, when the superior is a foreigner, the quality, and not the type of the relationship, is the crucial factor. However, an informal relationship becomes important when there are no foreigners. This may cause certain threats in a situation where the company expands internationally.

Authors: Booth Natalie , Ngwube Alexander , Appavu Brian , Shah Sanjay , Abruzzo Todd
Published: January 2024

Sickle cell disease (SCD) is a chronic hematologic disorder which causes progressive cerebral arteriopathy beginning in childhood. As a result, arterial ischemic stroke is a major cause of morbidity and mortality in SCD, and SCD is a leading cause of childhood stroke worldwide. Allogenic hematopoietic stem cell transplant (HSCT) may be curative for individuals with SCD. Long-term outcomes and effects are currently being studied. In this report, we describe a child with SCD who presented with arterial ischemic stroke at 6 years of age and was found to have a severe form of cerebral large vessel arteriopathy by catheter-directed angiography. The patient initially underwent revascularization surgery by indirect superficial temporal artery to middle cerebral artery bypass, and 1 year later, he underwent curative HSCT. Approximately 3 years after HSCT, repeat catheter-directed angiography revealed a striking reversal of cerebral large vessel arteriopathy. This article reveals a previously unrecognized and potentially beneficial effect of HSCT that may ameliorate cerebral large vessel arteriopathy and improve cerebrovascular health for children with SCD.
The influence of powdery mildew (Sawadaea bicornis (Wallr.) Miyabe) on chlorophyll fluorescence in Norway maple (Acer platanoides L.) seedlings

Published: January 2024

The article presents the results of research on impact of Sawadaea bicornis (Wallr.) Miyabe on the state of photosynthetic apparatus in Acer platanoides L. seedlings using a technique of chlorophyll fluorescence induction (ChlF) measurement, which at the present time can be implemented through the use of biosensors. The research was conducted in September 2022 in the territory of the Botanical Garden of Oles Honchar Dnipro National University. To diagnose a violation of the native chlorophyll photosynthesis in fresh leaves of A. platanoides, a portable fluorometer “Floratest” was used (selected spectral range for fluorescence intensity measurement was 670–800 nm). The research was carried out on fresh leaves of Norway maple seedlings both not unaffected and affected with powdery mildew. Analysis of the data obtained indicates a high sensitivity of the parameters of chlorophyll fluorescence induction to damage by the disease regardless of environmental conditions of local growth of A. platanoides seedlings. The high informativeness of induction changes in chlorophyll fluorescence in the structural organization of chloroplasts in Norway maple leaves determined by the parameters Fo, Fm, Fv, Fv/Fо, Fv/Fm, (Fm–Fst)/Fst, (Fp–Fо)/Fv was revealed. This study demonstrated the effectiveness of using the studied chlorophyll fluorescence parameters to detect severe stress in Norway maple seedlings caused by powdery mildew exposure when the fungus affects more than 50% of the leaf blade area. It is further necessary to conduct dynamic studies throughout the growing season to determine the effectiveness of using these parameters to detect mild stress in the early stages of infection. Therefore, our research showed that the method of induction of chlorophyll fluorescence using the “Floratest” device allows you to quickly determine the general condition of the plant by evaluating photosynthesis, which is the main life process. Analysis of chlorophyll fluorescence parameters is a powerful and effective tool for determining the effect of a parasitic fungus on a plant.
Transformation of vegetation under the conditions of the impact of military actions on the natural environment in Ukraine: A review
Authors: Fedenko V. S.
Published: January 2024

The negative consequences of various types of military activity on physical disturbances and chemical pollution of the environment are systematized. Factors of chemical pollution include potentially toxic elements, energetic compounds (explosives, fuels) and chemical warfare agents. According to the systematization of the available data on the long-term impact of military exercises and military actions on the territories of different countries on soil pollution, metal compounds dominate among potentially toxic elements, and organic pollutants dominate among energetic compounds. The combination of physical violations with multicomponent chemical pollution creates a specificity of the negative impact of the consequences of military activity on the natural environment compared to other anthropogenic factors. The following directions of research into the problem were noted: detection, distribution and ecotoxicology of chemical pollutants in natural environments, impact on biodiversity and vegetation dynamics, phytoremediation to reduce the level of chemical pollution, ecological and physiological factors of plant tolerance, degradation and detoxification of organic pollutants in plants. The tolerance of plants to the residues of explosive substances of various classes occurs due to the general pathways of biochemical transformation, which ensure the detoxification of organic xenobiotics. Taking into account the current state of the problem, literary data on the directions of research into the impact of military actions in Ukraine on the environment and the transformation of vegetation are summarized. Among these areas, the following were noted: assessment of damage caused by armed aggression to the natural environment; environmental monitoring of combat action; analysis of pollution of the natural environment; transformation of vegetation. Destructions of the natural environment as a result of combat action led to significant changes in vegetation, which are associated with ruderalization and adventization. The role of ruderal (including invasive) plants common in the flora of Ukraine under conditions of chemical pollution of habitats is analyzed. Increased tolerance of invasive plant species to high levels of metals and organic pollutants can be used for phytoremediation of disturbed areas, but will create a competitive advantage for more intensive spread compared to native species and new risks to phytodiversity.
The impact of the Botanical Garden of Oles Honchar Dnipro National University reconstruction on the soil aggregate structure
Authors: Golovnya A. V.
Published: January 2024

The reconstruction factor can significantly affect changes in soil cover. Physical soil properties changes are one of the main reasons for some plant species disappearance and the existing communities disintegration. The variation of soil aggregate structure in the areas affected by the reconstruction and in the areas without such within the Botanical Garden of Oles Honchar Dnipro National University has been studied. It is established that on all sample polygons there is a predominance of content of microfractions (less than 0.25 mm in size). But in the polygons affected by reconstruction, the proportion of microfractions is markedly higher compared to polygons without reconstruction. The sample polygon a, on which the reconstruction was carried out, differs significantly from the others in the lowest content of macrofractions, as well as mesoaggregates of size 7–10, 5–7 and 3–5 mm. At the same time, the highest content of fractions of 1–2, 0.5–1 and 0.25–0.5 mm is observed in this polygon. On polygons that were not affected by reconstruction (polygons c and d), there is a predominance of mesoaggregates 2–3 and 3–5 mm compared to polygons that were reconstructed (polygons a and b). The discriminant analysis made it possible to differentiate the polygons by the aggregate structure pacularities. By the peculiarities of the aggregate structure, the canonical root 1 separates polygon a from all other polygons, and the canonical root 2 opposes polygon b to polygons c and d. Root 1 correlates with the content of aggregates from 3 to 10 mm in size, while root 2 correlates with the content of micro-aggregates and aggregates from 0.25 to 0.5 mm in size. The influence of the reconstruction of the Botanical Garden of Oles Honchar Dnipro National University noticeably affected the aggregate structure of the soil reconstructed polygons, leading to a marked increase in microaggregates and a corresponding decrease in mesoaggregates, favorable for the growth of phytocenosis.

The influence of forest and vegetation conditions on the taxonomic characteristics and vital state of the common oak (Quercus robur L.) was analyzed. The research was conducted on four experimental plots in the Yatsevo tract: in the thalweg (CL3) and on the lower third of the slope (CL2) of the southern exposure of the mouth part and in the thalweg (CL3) and the upper third of the slope (CL1-2) of the same exposure in the middle part of the gully. In the thalweg of the middle part of the gully, a linden-pack oak forest with elm grows, the density of this stand (1700 pcs./ha) is the largest among the studied phytocoenoses. On the rest of the experimental plots, elm-pack oak forests grow with a density of 917 to 1150 pcs./ha. The average values of the main taxonomic parameters (height, diameter, cross-sectional area, and reserve) practically do not differ in Q. robur plants growing in the thalweg (CL3) and the lower third of the slope (CL2) of the mouth part of the tract. These indicators in thalweg plants (CL3) of the middle part of the gully are the highest among all experimental variants, and in individuals of the upper third of the slope (CL1-2) - are the lowest. In all studied hygrotopes, healthy trees prevail, with weakened individuals taking the second place by the number of individuals. The vital status index (Ln) shows that the thalweg stands in both the mouth and middle parts of the gully are healthy (Ln 86.3 and 84.3, respectively). The stands of the lower third of the slope (CL2) of the mouth part of the tract and the upper third of the slope (CL1-2) of the middle part are somewhat weakened (Ln 76.9 and 76.7). The pathologies of the crown and trunk of Q. robur trees in the experimental plots were analyzed. It was found that hygromesophilic conditions (CL3) are preferable for the formation of healthy stands.

Measuring the third mission of European Universities: A systematic literature review
Authors: Haj Taieb Sirine
Published: January 2024

In recent years, policymakers and academics have shown interest in understanding how universities could drive regional innovation. Universities are not solely focusing on research and education as their primary missions but are also asked to participate in the development of their regions. This has compelled universities to forge what is called a third mission, encompassing all social and economic activities of universities. Several attempts have been made to evaluate this concept, aiming to highlight the evolving role of universities and their relevance to policy and society. In this vein, this paper showcases existing attempts that aim to measure the impact of the third mission in European universities. This study consists of a systematic literature review studying journal articles published between 2001 and 2021. The purpose of this paper is to enumerate the existing measurements of the third mission and identify the different tensions related to it. This study shows that the literature encompasses three approaches for assessing the third mission. First, some studies incorporated the third mission into the overall evaluation of university performance. Second, other investigations aimed to capture this concept as a whole. Finally, several studies evaluated individual dimensions of the third mission independently.
A NANOFLUID COUPLE STRESS FLOW DUE TO POROUS STRETCHING AND SHRINKING SHEET WITH HEAT TRANSFER

Published: January 2024

The analysis of current work portrays the exact solution of couple stress fluid flow with heat transfer. Three varieties
of nanoparticles are placed inside the flow to achieve better thermal conductivity. A porous sheet inside the fluid flow is considered to yield new results of the study. With the use of similarity variables, the controlling partial differential equations of the issue are converted into ordinary differential equations. Analytical analysis is used to determine the domain and solution of the momentum and energy equations in terms of the Laguerre polynomial. In addition, skin friction and Nusselt number are also verified using nondimensional different controlling parameters, such as thermal radiation, the couple stress fluid parameter, solid volume fractions, mass transpiration, and so on, to verify the results of this work. The present work is very good argument with a previously published paper, and it also covers many industrial applications, namely entropy generation, polymer production, automotive cooling systems, and microelectronics.
Archaeological landscape of the Warta valley in the Częstochowa region of Mirów
Authors: Młodkowska-Przepiórowska Iwona , Koj Jacek
Published: January 2024

The authors report the issues of cultural landscape and archaeological landscape in the Warta valley near Wyczerpy and Mirów, the districts of Czestochowa. The cultural landscape is defined as an anthropogenic fragment of geographical space, creating a specific structure, manifesting itself with regional marked individuality. Whereas, the archaeological landscape is defined as a cultural landscape, in which the dominant elements are archaeological sites (objects). The resources of archaeological cultural assets forming the archaeological landscape of the valley of the Warta river are presented on the attached cartographic material. There are short information notes inserted giving the basic literature concerning the most valuable and important archaeological sites (settlements, cemeteries, strongholds) from various periods (from the Bronze Age to the Middle Ages). At the end, feasible actions aimed at preserving and documenting the landscape and archaeological heritage of the discussed part of the Warta valley are presented, as well as initiatives that have already been taken in the field of spatial planning and development of the area.

A prática clínica durante a formação em psicologia é realizada muitas vezes em clínicas-escola, e conhecer características da clientela atendida é fundamental para o aprimoramento do atendimento. Objetivou-se levantar o perfil de pacientes atendidos numa clínica-escola, nas modalidades infantil, adolescente, adulto, casal e família de uma clínica-escola de psicologia localizada no Rio Grande do Sul.  Realizou-se um levantamento de perfil de 667 prontuários de pacientes infantis, adolescentes, adultos e de casal e família atendidos, entre os anos de 2011 a 2017, investigando dados sociodemográficos, tipo de avaliação inicial conduzida, número de sessões, teoria utilizada, quem encaminhou, motivo da busca, hipótese diagnóstica e razão do término do atendimento. Identificou-se características específicas destas variáveis conforme a faixa de idade e tipo de atendimento. Houve um expressivo número de prontuários com dados incompletos, dificultando a análise dos dados. Um melhor controle das informações dos prontuários permite um conhecimento mais detalhado do perfil atendido em clínicas-escola.
Capital psicológico: relações entre desenho do trabalho, engajamento e intenção de rotatividade
Authors: Hokama Erica , Martins Maria do Carmo Fernandes
Published: January 2024

Este estudo investigou as relações entre capital psicológico, desenho do trabalho, engajamento e intenção de rotatividade. Trata-se de um estudo quantitativo e de corte transversal com 268 participantes. Utilizou-se como Instrumentos: a) Questionário de Desenho do Trabalho, b) Escala de Capital Psicológico, c) Escala de Engajamento no Trabalho de Utrecht, d) Escala Intenção de Rotatividade e e) Questionário de dados sociodemográficos. Análises de regressão apontaram que fatores do desenho do trabalho e capital psicológico são fatores preditivos de engajamento no trabalho e de intenção de rotatividade. Os resultados indicaram ainda que desenho do trabalho e capital psicológico se relacionavam positivamente com engajamento no trabalho e negativamente com intenção de rotatividade. Revelaram também que capital psicológico é um fator supressor na relação entre especialização e engajamento no trabalho e modera a relação entre solução de problemas e intenção de rotatividade. Ademais, fatores do desenho do trabalho (características da tarefa e do trabalho, características sociais e o contexto do trabalho) e capital psicológico explicam engajamento no trabalho e intenção de rotatividade. São destacadas a originalidade do estudo, suas colaborações teóricas e aplicadas ao contexto de trabalho, destacando-se suas limitações.

Published: January 2024

O presente estudo investigou o impacto da indução de estereótipo e a influência da desaprovação na memória de crianças. Participaram 40 pré-escolares (23 meninas, entre 4 e 6 anos (M= 62,7 meses, DP=8,03) e 36 escolares (17 meninas), entre 7 e 8 anos (M=95,4 meses, DP= 6,21) que receberam a visita de um “cientista” que realizou uma demonstração de ciências. As transmissões do estereótipo e desaprovação foram realizadas através de vídeos. Entrevistas foram realizadas para avaliar a memória das crianças acerca do evento. Os principais resultados indicam que crianças escolares recordaram mais informações acuradas que crianças pré-escolares. Ademais, existe uma relação positiva entre recordação de memórias acuradas e produção de memórias relativas ao estereótipo, que é moderada pela idade dos participantes.  A principal contribuição é a investigação empírica do impacto que a faixa etária exerce na acurácia dos relatos de memória, e na relação entre memória acurada e falsas memórias.
