Rare, endangered and protected plant species of synanthropic flora of the Kampinos National Park (Central Poland)
Authors: Kirpluk Izabella , Bomanowska Anna
Published: May 2024

The aim of this paper is to present the rare, endangered and protected plant taxons growing in the synanthropic habitats of the Kampinos National Park. The research was conducted on agricultural fields (still maintained) and in ruderal habitats in over a dozen abandoned villages in the Kampinos Forest. Among species considered to be endangered are: Agrostemma githago, Asperugo procumbens, Atriplex rosea, Camelina microcarpa, Centunculus minimus, Filago arvensis, Fumaria officinalis, Gagea pratensis, Holosteum umbellatum, Myosurus minimus, Pulicaria vulgaris and Radiola linoides. To the category of rare plant species belong: Anthemis ruthenica, Arabis glabra, Arnoseris minima, Chenopodium ficifolium, Ch. pedunculare and Euphorbia peplus. Species protected by law, found during the study, include: Epipactis helleborine, Jovibarba sobolifera and Helichrysum arenarium. According to our observations some of the segetal plant species, for example Filago arvensis, Centaurea cyanus and Papaver rhoeas, have tendencies to habitat change. These plant species move from agricultural fields to ruderal habitats. In the Kampinos Forest’s synanthropic habitats the species from seminatural non-forest habitats such as Sedum sexangulare, Eryngium planum, Cerastium semidecandrum, find their place.

In this paper, we solve the question completely raised by Feng Qi and Dongkyu Lim in paper “Monotonicity properties for a ratio of finite many gamma functions” published in Advances in Difference Equations and get some properties about ratios of finitely many gamma functions such as complete monotonicity, logarithmically complete monotonicity, the Bernstein function property, null point and extreme value.
Some new uniqueness and Ulam–Hyers type stability results for nonlinear fractional neutral hybrid differential equations with time-varying lags
Authors: Dien Nguyen Minh
Published: May 2024

This paper deals with some qualitative properties of solutions to nonlinear neutral hybrid differential equations connected to ψ-Caputo fractional derivative with time-varying lags. First, we demonstrate the problem possesses a mild solution uniquely where the source function may have temporal singularities. Second, in some cases, we indicate that the problem possesses a unique mild solution under some weaker conditions than the previous one. Third, we also obtain a result on a global mild solution for the problem. Finally, the results are further enriched by studying a new type of Ulam–Hyers stability for the main equation. The main results are obtained by applying the nice inequality, first proposed and proven in this paper. Some befit examples are given to justify the applicability of the main results.
Weighted 1MP and MP1 inverses for operators
Authors: Mosić Dijana , Marovt Janko
Published: May 2024

The main aim of this paper is to extend the concepts of the 1MP and MP1 inverses defined for rectangular complex matrices. We present the weighted 1MP and MP1 inverses for a bounded linear operator between two Hilbert spaces as two new kinds of generalized inverses. The notions of the weighted 1MP and MP1 inverses are new in the context of rectangular complex matrices too. We establish a number of characterizations and some representations of the weighted 1MP and MP1 inverses. Several operator equations are solved applying the weighted 1MP and MP1 inverses. A special case of one of these equations is the normal equation which is related with the least-squares solution. As consequences of our results, we obtain new properties of the 1MP and MP1 inverses.
Operator Bohr-type inequalities
Authors: Sababheh Mohammad , Conde Cristian , Moradi Hamid Reza
Published: May 2024

The classical Bohr inequality for scalars was extended to the non-commutative case of Hilbert space operators in the literature. The sole goal of this article is to discuss the operator Bohr inequality and present some of its new variants. This includes fresh reverses and refinements of this inequality with applications towards an operator’s real and imaginary parts, not to forget the new discussion of different domains of the parameters. One further application towards the operator Dunkl-Williams inequality will be presented too. While the new results are interesting, we emphasize that the approach used to explore these inequalities differs from the existing literature methods for this context.
Exploring innovative food in a developing country: Edible insects as a sustainable option
Authors: Boustani Nada Mallah , Guiné Raquel P. F.
Published: May 2024

Today's consumers are becoming more aware of what they eat and the benefits that a healthy diet can provide. Edible insects (EIs) have recently been proposed as a sustainable, protein-rich alternative food source. Consumers' adoption of insects as part of their diet may be influenced by their awareness of this source of food. In this context, the current study investigated the level of knowledge about EI in a developing country, with the goal of understanding how Lebanese people perceive EI as food, as well as whether there are any sociodemographic or socioeconomic differences in their knowledge and motivation to accept EI as food. This was a cross-sectional study conducted using a questionnaire survey of 357 Lebanese participants. Basic descriptive statistics were employed to analyze the data, which were supplemented with statistical tests such as ANOVA for comparisons between three or more groups with post hoc to examine any group differences and Cronbach's alpha to assess internal scale reliability. The search for differences according to sociodemographic and socioeconomic characteristics showed significant differences between age groups and levels of education. Additionally, the results showed that the items used to assess the EI dimensions scale have a very high internal consistency, with the lowest being nutritional aspects (α = 0.669) and the highest being health effects (α = 0.797). This work is relevant because it highlights the EI food dimensions that influence people’s acceptance in Lebanon, which is facing social and economic crises while highlighting many age inequalities and education level differences. Based on the findings, individual EI dimensions were discovered, allowing for strategies deployment to effectively improve knowledge and eventually respond to a Sustainable Development Goal objective even in a nation where this is not a traditional practice.
Genotype by environment interaction and performance stability of common bean (Phaseolus vulgaris L.) cultivars grown in Dawuro zone, Southwestern Ethiopia
Authors: Daemo Berhanu Bilate
Published: May 2024

The performance of most crop genotypes varies significantly depending on their genotype–environment interactions. Providing information on high-yielding and well-adapted common bean genotypes in a given environment is crucial for small-holder farmers to boost their productivity. A field trial was conducted at the Gendo and Wara locations over two consecutive seasons to understand genotype–environment interactions on grain yield and to identify and select common bean genotypes that were better adapted and had high yield potential for production. Ten genotypes were evaluated for their performance using a randomized complete block design with three replications. The AMMI and GGE models were used to identify superior genotypes regarding their mean grain yield performance. The AMMI analysis of variance results showed that grain yield was significantly (p ≤ 0.05) influenced by genotype–environment interactions. This shows that genotypes varied in grain yield mean performance across environments, indicating the possibility of selecting suitable genotypes with specific and broad adaptability. The sum of squares factor indicated that grain yield variation was contributed by the genotype (61.0%), followed by the environment (29.80%) and the genotype–environment interaction effect (9.20%) of the total variation. The AMMI and GGE biplot analysis results showed that SER-119 and SER-125 were identified as the best genotypes regarding their mean grain yield performance. Additionally, the genotype selection index analysis result indicated that SER-119 and SER-125 were stable and consistently exhibited high mean performance in all evaluated settings. Therefore, SER-119 and SER-125 are prime candidates for production in various agroecologies suitable for common bean cultivation in Dawuro zones. The use of tools like GGE biplots and AMMI analysis helped visualize the genotype–environment interactions, aiding in the selection of appropriate genotypes for both specific and wide adaptability.

This study pioneers the synthesis of porous Ag/ZnO nanosheets, focusing on their role as a catalyst in Knoevenagel condensation. Notably, these nanosheets display exceptional catalytic efficacy and captivating antibacterial properties. The research delves into the Ag/ZnO catalyst’s recyclability and proposes a potential reaction mechanism, marking the first comprehensive exploration of Knoevenagel condensation on porous Ag/ZnO nanosheets. Key findings underscore the successful synthesis of coumarin derivatives using various o-hydroxy benzaldehyde and 1,3-dicarbonyl compounds, with nano-Ag/ZnO serving as a catalyst via a monomode microwave-assisted approach. X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), Transmission Electron Microscopy (TEM) and UV–Vis spectroscopy were used in conjunction with other physicochemical methods to characterize the synthesized catalytic samples. The method boasts advantages such as high product yields, brief reaction durations, and the ability to reuse the catalyst for multiple cycles. The Ag/ZnO nanosheets, functioning as an acid catalyst, activate carbonyl groups and facilitate their interaction with methylene-containing active molecules. In addition, antibacterial activity assessments demonstrate the superior effectiveness of Ag/ZnO nanocomposites compared to ZnO nanosheets against Staphylococcus aureus germs. This multifaceted study not only advances catalytic synthesis but also unveils promising biological applications of porous Ag/ZnO nanosheets.

Published: May 2024

There is interest in optimizing peptide receptor radionuclide therapy (PRRT) for the management of metastatic neuroendocrine neoplasms (NEN). The addition of stereotactic body radiation therapy (SBRT) may provide synergistic benefits by targeting specific sites of disease that may represent areas of tumor heterogeneity. Little is known about the efficacy or potential toxicity of this approach; understanding the outcomes of patients treated with these two modalities in a sequential fashion will provide insights into the appropriateness of embarking on a combined therapy strategy. An institutional retrospective review of 21 patients with NEN treated with sequential PRRT and SBRT (64 targets) was performed. Median overall survival and progression-free survival were 19.6 months and 12.8 months, respectively. Median time to local recurrence at the SBRT site was not reached, with rates at 12 and 24 months of 1.8% and 5.9%, respectively. The toxicity profile remains favorable. Given the safety and efficacy of sequential SBRT and PRRT, further trials evaluating a concurrent treatment approach may be warranted.

How old is too old to fight in boxing? Age is not just a number
Authors: K Sethi Nitin
Published: May 2024

Professional boxing is a physically demanding combat sport. In boxing every punch thrown to the head is thrown with the intention of winning by causing a knockout (KO). As a result, concussive head injuries are common in boxing. Traumatic subdural hematoma remains the most common cause of boxing related mortality. As older boxers (age greater than 40) enter the ring, concern is raised for their neurological health. How old is too old to fight in boxing? Should there be a cut-off age beyond which boxers should not be allowed to compete professionally?

Authors: Adinata Rangga Satria , Hanami Yuliana
Published: May 2024

Adolescents spend a lot of time at school because schools are centers of activity for them. Thus, it is normal for students to feel supported, comfortable, and connected to all components of the school. These feelings can make students think of themselves as part of their school or known as school belongings. This research was conducted to explore what factors can affect school belonging and to find the factors that have the most meaningful influence on school belonging for high school students in Indonesia. This research used a qualitative approach with a generic qualitative approach, and consisted of five participants who were 10th and 11th grade high school students attending schools in Bandung. Data analysis uses reflexive thematic analysis. The results of the study revealed that four themes could affect school belonging for students at school, including relationships with school members, adequate learning facilities and infrastructure, students' participation in extracurricular activities, and the match between students' interests and their school majors. On the other hand, it was found that peers were a factor that consistently influenced students' school belongings because it is consistently mentioned by every subject in this study.
Representaciones de la Patagonia en la prensa argentina de los años treinta. Cronistas, reporteros y escritores viajeros en el periodismo masivo y comercial
Authors: Juárez Laura
Published: May 2024

La prensa masiva y popular de los años treinta constituye una de las zonas en las que se retoman y actualizan distintas representaciones de la Patagonia y el sur argentino. Efectivamente, en las publicaciones de ese entonces puede constatarse una renovada presencia de viajeros y periodistas que reescriben el territorio patagónico: González Tuñón y Arturo Mom, en Crítica; Roberto Arlt en El Mundo, Soiza Reilly en Caras y Caretas y artículos diversos aparecidos en la revista femenina El Hogar. El presente trabajo selecciona algunas de estas colaboraciones y analiza cómo se reconfiguran allí diversos imaginarios y «saberes» sobre la Patagonia para cristalizarse en la reelaboración escrita de ciertas figuras principales: la Patagonia como espacio promisorio, pero alejado y distante, al que es preciso argentinizar, y la Patagonia y el sur como territorio maravilloso, terreno propicio para lo aventurero y lo abyecto, aquello opuesto al orden de lo convencional. En esta reconfiguración, además de que los textos entran en un diálogo fluctuante con ciertos proyectos estatales de ese entonces (de los que también se distancian) y con una amplia biblioteca, es crucial el impacto de las formas de intervención de la prensa comercial y su búsqueda de impacto eficaz sobre el público lector.

This work proposes the optimisation of the ultrasound assisted extraction (UAE) for total phenolic content (TPC) from potato peels (PP). The optimised extract was obtained using ethanol 20% (v/v) for 30 min at 40 °C, and it was found to be rich in total phenolics (45.03 ± 4.16 mg GAE/g DM) and flavonoids (7.52 EQ/g DM) and exerted a good antioxidant effect with IC50s of 125.42 ± 2.78, 87.21 ± 7.72, and 200.77 ± 13.38 μg mL−1 for DPPH, phosphomolybdate, and FRAP, respectively. PP were used for the fresh cheese formulation, and this supplementation did not impact its physicochemical properties; however, the phenol content and antioxidant capacity of formulated cheeses were improved. PP-enriched fresh cheese presented a good acceptability, even better than the control.

3D modelling of historic buildings based on integrated data from airborne and terrestrial laser scanning
Authors: Kwoczyńska Bogusława , Nowak Kinga , Woźniak Krzysztof
Published: May 2024

Currently, the modelling of historic buildings is most often performed on the basis of data obtained by terrestrial laser scanning. It ensures both the speed of information acquisition and the high accuracy of the final elaboration. However, there are situations in which the terrain layout or the structure of the building limits the possibility of obtaining full information on its shape. In such situations, the solution is to integrate data from various measurement devices. In the case of creating a full 3D model of large buildings, one of the ways to supplement the data, especially the roof of the building, is to use data from airborne laser scanning. The research used the integration of airborne laser scanning data with data recorded with the Leica ScanStation P40 terrestrial laser scanner. Combined point clouds were used for 3D modelling of two different historic buildings in Krakow. Modelling was performed with the Bentley CAD software and in Leica Cyclon 3DR and 3DReshaper. The accuracy of data integration was determined and the advantages and disadvantages of using the above-mentioned software for 3D modelling of architectural objects were shown. The result of the study is a 3D model of St. Florian’s Gate and the Palace of Art in Krakow.
Application of a method for the multidimensional assessment of the current state of polish health resorts on the example of piwniczna and Krynica-Zdrój
Authors: Olczak Barbara , Furtak Natalia , Król Angelika
Published: May 2024

The presented research concerns a multi-faceted assessment of the existing condition of selected Polish health resorts. The aim of the research was to apply the above-mentioned evaluation in the context of possibilities to improve the condition of the space, attractiveness, and functioning of Polish spas that have been struggling with a number of problems of a political and economic nature, which originated in World War Two. Although intended to improve the functional environment of health resorts, the Health Resort Act contains provisions perceived as barriers to the development of health-related and other associated functions that are necessary for the appropriate operation of health resorts. This leads to a conclusion that the function – however deeply rooted in Polish culture – requires a new approach to health resort functioning in today’s circumstances. The new approach should be founded on a deep, careful, and detailed diagnosis of the condition of health resorts in Poland, which will perhaps enable the application of a multi-faceted assessment of the existing condition (MCSA). MCSA is modelled on a method developed in the 1970s in the United States of America by a landscape architect and spatial planner Ian McHarg. The main idea behind the development and application of this assessment method is to facilitate decision-making for planning, design, and investment activities, with a particular focus on local government. The case study carried out by the authors concerns two Polish health resorts located in the Małopolskie Voivodeship.
Application of TLS and UAV data integration to model specific objects
Authors: Kwoczyńska Bogusława , Gudz Paweł
Published: May 2024

Contemporary measurement techniques facilitate the rapid and highly precise development of three-dimensional models of any spatial object. Terrestrial laser scanning (TLS) stands as one of the most precise methodologies. Nevertheless, instances arise wherein restrictions imposed by the terrain configuration or infrastructure design impede the acquisition of comprehensive information regarding its geometry. In such scenarios, the optimal resolution lies in the integration of data sourced from diverse measurement instruments. In the context of working with large objects, the optimal approach to capturing comprehensive data, particularly pertaining to the upper parts, involves utilising an unmanned aerial vehicle (UAV). The high resolution of images acquired at a low altitude enables the generation of a point cloud with remarkable accuracy, delivering a satisfactory outcome. When it comes to the modelling of special objects, such as brine graduation towers, the selection of suitable software that facilitates the creation of realistic three-dimensional models is of paramount significance. The study utilised the integration of data acquired from a low altitude using the DJI Air 2S Fly More Combo unmanned aerial vehicle. Diverse mission types were employed, and the data was subsequently recorded using a terrestrial Leica ScanStation P40 laser scanner. The research was conducted on a brine graduation tower situated above the Nowa Huta reservoir in Kraków. The tower’s dimensions necessitated the incorporation of TLS and UAV data. This study analyses three 3D models of the brine graduation tower in Nowa Huta. The models were generated using various computer programmes, namely MeshLab, Agisoft Metashape, and Cyclone 3DR, each of which demonstrated specific capabilities and suitability for modelling a special object like a brine graduation tower. The accuracy of the constructed three-dimensional model of the tower was determined by comparing sections that were measured in the field on the structure between photographic points marked by discs and the equivalent points on the model. Eighteen sections were measured, yielding a mean error of 0.039 m.
Conceptual design for a calligraphy park in the hospital and park complex in Kobierzyn
Authors: Baster Przemysław , Topa Karolina
Published: May 2024

The hospital and park complex in Kobierzyn is one of the few sites of its kind both in Poland and in Europe. It was designed at the beginning of the 19th century according to the idea of a city-garden. Although there are currently plans for its complete revalorisation, the paper presents the author’s design concept of expanding the hospital park with the area of the neighbouring former arable fields, which, according to the authors, meets contemporary realities and needs. The designed park - together with the neighbouring manor buildings - is harmoniously incorporated into the whole of the hospital-park complex, forming a coherent spatial composition. The design guidelines and solutions are adapted to the existing compositional axes, Art Nouveau aesthetic canons, buildings, trees and even the water reservoir. The project incorporates the design principles of Polish calligraphic parks established at the turn of the 19th and 20th centuries, whose compositional rules dominated Polish garden art for several decades and continue to resonate today. This little-known style crowned the development of 19th-century garden art of free forms - the apparent naturalness of the forms was in fact a space fully subordinated to the designer’s efforts. It was also the first composite style that combined geometric and free forms, leaving its mark on contemporary works and continuing to fascinate today with its compositional principles. The project proves the timelessness of these principles and the desirability of employing historical solutions in landscape design.
Recovery of Discrete-Time Signal Based on the Moving Average Model and Estimation of the Samples Correlation in Forward and Reverse Forecasting
Authors: Yakimov Vladimir
Published: May 2024

The article discusses the development of mathematical support for the recovery of the values of discrete-time sequence samples obtained as a result of uniform sampling of a continuous signal. The recovery problem of discrete-time sequence samples is solved for a signal that can be considered stationary or stationary at least in a broad sense (quasi-stationary). The development of mathematical support for the recovery of the values of signal samples was carried out on the basis of constructing a moving average model and estimating the correlation of signal samples over time with forward and reverse forecasting. Estimates of the signal correlation function necessary to recover sample sections with lost values are calculated from samples with known values. Correlation function estimates can be calculated regardless of the location of the recovery area when the condition of stationarity of the signal is met. The obtained estimates of the correlation function samples can be used for both forward and reverse forecasting. Moreover, even if it is necessary to recover several problem sections, it is enough to calculate only once the sample of correlation function estimates necessary for their restoration. The resulting mathematical solution to the problem became the basis for the development of algorithmic support. Test tests and functional checks of the algorithmic support were carried out on the basis of simulation using a signal model representing an additive sum of harmonic components with random initial phases. The simulation results showed that the calculation of estimates of the lost sample values is carried out with a fairly low error, both in forward and reverse forecasting, as well as when they are used together. In practice, the choice of a sequence recovery algorithm based on forward or reverse forecasting will be determined based on the actual conditions of its processing. In particular, if previous samples with known values are not enough to carry out forward forecasting, then the reverse forecasting procedure is implemented and vice versa. The developed algorithmic support can be implemented in the form of metrologically significant software for digital signal processing systems.
Classification of Spatial Temporal Patterns Based on Neuromorphic Networks
Authors: Gundelakh Filipp , Stankevich Lev
Published: May 2024

This work is devoted to the problems of developing neuromorphic classifiers of spatiotemporal patterns, as well as their application in neurointerfaces. Classifiers of spatiotemporal patterns based on neural networks, support vector machines, deep neural networks, and Riemannian geometry are considered. A comparative study of these classifiers is carried out in the plane of the accuracy of multiclass recognition of electroencephalographic signals showing time-dependent bioelectrical activity in different areas of the brain during the imagination of different movements. It is shown that such classifiers can provide an accuracy of 60-80% when recognizing from two to four classes of imaginary movements. A new type of classifier based on a neuromorphic network, based on the biosimilar neurons built on the Izhikevich model, is proposed. The network processes input spike sequences and generates pulse streams of different frequencies at the outputs. The network is trained using the Supervised STDP algorithm based on labeled information containing examples of the correct recognition of the required pattern classes. The recognized pattern class is determined by the maximum frequency of the output sequence. The neuromorphic classifier showed an average classification accuracy of 90% for 4 classes of imaginary commands and a maximum of 95%. By modeling the robot control task in the virtual environment it is shown that such accuracy is sufficient for the effective use of the classifier as part of a non-invasive brain-computer interface for non-contact control of robotic devices.
Norm Violations and Behavioral Spillovers: Evidence From the Lab and The Field
Authors: Goerg Sebastian J. , Himmler Oliver , König Tobias
Published: May 2024

This paper explores the contagion effects of norm-violating behavior across decision situations.Through a series of laboratory and field experiments, we empirically establish the conditions under which norm-breaking behavior in one decision situation leads individuals who observe this to violatennorms in other, distinct decision situations. Our laboratory findings show that these spillover effects are more pronounced when the norms underlying the decision situations are perceived to be similar. However, spillovers can also affect decision situations governed by relatively dissimilar norms if the observers of norm violations have had the opportunity to first violate the same norm as the observed violator themselves. In an accompanying field experiment, we underscore the economic importance of norm similarity for spillover effects. When workers are exposed to information about celebrities evading taxes, they exhibit significantly higher rates of workplace theft than those in the control group, yet this exposure does not negatively affect work morale.

Published: May 2024

The focus of this study was to investigate the causes of variance in assessed rateable values from the point of view of property rating assessors. Valuation is the foundation of property rating administration. The correctness of the assessed rateable values significantly impacts other components of rating administration. The rateable value is considered to be correct when the variance in the valuations of a rating authority and objector is within an acceptable margin of variance. Purposive sampling method was adopted among registered estate surveyors and valuers in Kwara State, Nigeria. This study adopted qualitative research approach. The qualitative data were obtained from an interview survey with 8 valuers, which content analysis was employed to analyze the data.  Findings showed that experience in rating valuation, valuers’ negligence, unrealistic valuation assumption and integrity of the valuers were the causes of variance in rating valuation. Other factors identified are comprehensiveness of the law, the explicitness of the law, absence of quality control, absence of a professional sanction, availability of market indices and clients’ influence. The findings could have practical usefulness on rating authority, estate surveying and valuation regulatory board and the assessor. This could avail the stakeholders of the requisite information on the root causes of variance in assessment and possible ways of correcting such variances. The correction could pave way for the role of valuation in rating administration.

Advantages and disadvantages of digital reading: technical university students’ perspective
Authors: Nikolaeva Natalja , Inozemtseva Kira , Lezhneva Ekaterina
Published: May 2024

The article considers implementation of the state strategy for digital transformation of the Russian education, in particular, the integration of digital reading in the educational space of technical universities. It determines the ongoing scientific discussions about digitalization and its impact on such cognitive processes as perception, interpretation, and assimilation of information by university students. Reading is fundamental to learning and education. Therefore, it is relevant to analyze digital reading in the academic environment including its learning potential, as well as advantages and disadvantages. Although many domestic and foreign authors have written about digital reading, there is a lack of empirical studies analyzing the impact of modern technologies on readers’ perceptions of digital resources. Our article aims to fill this gap. The goal is to determine the technical university students’ attitudes towards digital reading, its advantages and disadvantages. We also identify methods for enhancing the use of digital reading in the university’s educational environment. Our pedagogical research employs such empirical methods as questionnaires, pedagogical observation, and interviews in the form of free frontal discussion. Quantitative and statistical analyses are used to process and interpret the obtained data. The novelty consists in digital reading as a new educational technology and the readers’ attitude towards it. The study involves 1st to 3rd year students from Bauman Moscow State Technical University (n = 222). The data obtained do not only identify the students’ assessments of the digital integration in the Russian higher education, but also outlines ways to optimize the use of digital technologies in the educational process. The study shows that the shift from traditional print media to digital reading has both advantages and disadvantages. It requires students to communicate with interactive multimodal texts on digital media, which can affect their cognitive, emotional, volitional, and physical development. This places special demands on the competence of university teachers.

Charcoal fines are co-products of the wood carbonization process, unwanted because they reduce the gravimetric yield of the main product, charcoal. It can be produced due to the carbonization process, during the storage and transport of charcoal. Pelletizing charcoal fines increases the energy density of this material, producing a homogeneous fuel with lower moisture content, enabling burning in equipment with high energy efficiency, in addition to desirable properties in energy products such as high fixed carbon content and low moisture content. This study evaluated the effect of moisture content and drying time on the production of black pellets from charcoal fines bound with rice starch (Oryza sativa) on the physicochemical and mechanical characteristics. Black pellets were produced using two proportions of water (10 or 20%) and a drying time of 4 or 6 hours. Black pellets were evaluated for their proximate analysis, elemental composition, moisture content, size, apparent density, calorific value and energy density. The addition of water did not affect the content of volatile matter, ash, and fixed carbon, while the treatment with addition of 20% water and four hours of drying showed a higher moisture content (3.34%). The addition of water allowed for better heat conduction and particle arrangement, producing pellets with a durability greater than 98%. The better arrangement promoted by the addition of 20% water also increased the density of the pellets, resulting in greater energy density. Black pellets can be considered an alternative for residential heating, with T3 treatment (20% - 4h) with a high energy density and better performance in terms of desirable properties for use and commercialization according to the standard EN 14961-6.

The paper deals with comparative analysis of the main abiotic factors and phytoplankton taxonomic characteristics in various ecosystems of the Dnieper River, including the head cascade Kyiv Reservoir and the natural Dnieper estuary. Investigations were carried out in summer seasons of 2014-2020. The studied water bodies differ significantly in their physical, geographic, climatic, hydrological, and hydrochemical characteristics. However, they have some common features: both water bodies are large highly productive lentic ecosystems with similar morphometric parameters. As regards phytoplankton taxonomic diversity, the similarities include the same rank distribution of leading divisions and high species richness of summer phytoplankton. A number of differences has also been observed: a higher share of Bacillariophyta in the reservoir and higher shares of Cyanobacteria and Miozoa in the estuary; higher species richness of phytoplankton in the Dnieper estuary compared to the Kyiv Reservoir; a large number of species, occurring only in one of the studied ecosystems - 75 species in the Kyiv Reservoir and 88 species in the Dnieper estuary. The obtained data can serve as a background for assessing an adverse effect of the Russia's military aggression and arising hazards for the Dnieper ecosystems
of Ukraine.
DERIVATIVE-BASED SHAPLEY VALUE FOR GLOBAL SENSITIVITY ANALYSIS AND MACHINE LEARNING EXPLAINABILITY
Authors: Duan Hui , Okten Giray
Published: May 2024

We introduce a new Shapley value approach for global sensitivity analysis and machine learning explainability. The method is based on the first-order partial derivatives of the underlying function. The computational complexity of the method is linear in dimension (number of features), as opposed to the exponential complexity of other Shapley value
approaches in the literature. Examples from global sensitivity analysis and machine learning are used to compare the method numerically with activity scores, SHAP, and KernelSHAP.
The Cultural Roots of Gender Bias and Horizontal Hostility in the Workplace
Authors: Yanıkoglu Özge
Published: May 2024

A healthy workplace is an environment where everyone can work peacefully with both sexes, regardless of their roles as leaders, subordinates, or colleagues. Unfortunately, achieving this ideal remains elusive, and the situation is more challenging for women, due to their underrepresentation in many industries. Studies have revealed that especially women in management positions are subject to biased evaluations by their subordinates, colleagues, and managers. A deep understanding of the cultural underpinnings is essential to fully grasp the existence, prevalence and influence of gender bias in the workplace. Thus, this study aims to impartially investigate the cultural factors that may shape employees' preferences for the gender of their managers, alongside exploring potential biases towards managerial gender from a cultural standpoint. To achieve the research goals, an open-ended survey was administered to 302 professionals in Istanbul. The results indicate a prevalent bias against female managers by individuals of both genders. Moreover, the study uncovers that women are prone to harboring more prejudiced views towards their female peers and superiors. These insights are analyzed through a cultural lens, and recommendations for management are proposed.

Antecedentes: Los periodos de sequía en el Desierto Sonorense aumentan el interés por cultivos con baja huella hídrica. Stenocereus thurberi es una alternativa, incluyendo beneficios económicos para los pobladores.
Hipótesis: La propagación vegetativa de tallos con areolas diferenciadas de Stenocereus thurberi con fines productivos, mostrará una alta supervivencia tomando en cuenta los patrones estacionales, actividad metabólica y asimilación de CO2, reflejando así la adaptabilidad, resistencia y productividad de la especie.
Especie de estudio: Stenocereus thurberi.
Sitio de estudio y fechas: Hermosillo, Sonora, México; 2014.
Métodos: Se evaluó supervivencia de tallos propagados vegetativamente, producción de calor metabólico (CM) de areolas reproductivas, intercepción de luz diaria integrada (LDI) y asimilación instantánea de CO2.
Resultados: Los tallos mostraron una supervivencia del 100 %, crecimiento vegetativo anual de 9.3 ± 0.6 cm y producción de 2.0 ± 0.8 frutos por tallo. La mayor cantidad de LDI se registró en mayo (27.2 mol m-2 d-1) y el lado oeste (23.4 mol m-2 d-1). Las areolas reproductivas mostraron mayor producción de CM en mayo con 2 µW mg-1 peso seco (ps) y el mayor gasto energético con 1,759.6 kJ mol-1. La menor tasa respiratoria en areolas fue en junio con 0.003 nmol mg-1s-1 mg-1 ps. Las tasas de mayor asimilación de CO2 se presentaron en marzo, septiembre y octubre con 6.3, 3.8 y 6.5 µmol CO2 m-2s-1, respectivamente.
Conclusiones: Es posible reproducir vegetativamente pitayas a partir de tallos con areolas reproductivas diferenciadas con fines productivos, promoviendo un cultivo eficiente con bajo consumo de agua y potencial económico.
Disiplinlerarası restorasyon çalışması: Hasankeyf Kalesindeki tarihi Küçük Saray'ın yerinde yükseltilmesi
Authors: Sevgi Serap
Published: May 2024

Ilısu Barajı ve HES projesi rezervuar alanında kalan Tarihi Hasankeyf yerleşiminin "Aşağı Şehir" denilen Dicle Nehri'nin iki kıyısındaki anıtları ve baraj maksimum su kotu (+527,86 m.) üzerinde kalan "Yukarı Şehir" diye anılan "Hasankeyf İç Kale Bölgesi'nin kayaç zemini, baraj gölünde biriken sudan doğrudan, üzerindeki tarihi anıtlar ise dolaylı şekilde etkilenmektedir. Kale bölgesinin zemini ve Küçük Saray'ın üzerine inşa edildiği kaya bloğunda; jeoteknik incelemeler, laboratuvar testleriyle desteklenerek kayaçların özellikleri incelenmiştir. Mevcut durumda ıslanma-kuruma ve donma-çözünme etkisiyle yamaçlardaki kayaçlarda kopmalar nedeniyle, baraj gölünde birikecek suyun kuru formasyondaki bu kayaçlara olumsuz etkileri olacağı belirlenmiştir. Kalenin kayaçlarının dolayısıyla üzerindeki kültür varlıklarının korunması için güney, kuzey ve doğu yönündeki vadilere, baraj maksimum su kotuna kadar doğal malzemelerle dolgu yapılarak, suyun kireç taşı kayaçlarda oluşturacağı aşındırıcı etki ve iç bölgelere sızıntılar azaltılmıştır. Küçük Saray'ın (12-13.yüzyıl) zemin kotunun, Kale çevresine yapılan koruma dolgusundan aşağı kalması nedeniyle, çevresine ters baraj sistemi yapılarak anıt yerinde korunmuştur. Ancak su seviyesi +524,00 kotuna ulaştığında baraj gölünden su sızıntıları anıtın çevresinde birikerek göllenmiş ve restorasyonu yapılan anıtta yeni bozulmalara oluşmuştur. Anıtın tekrar suya maruz kalması mimari ve yapısal bütünlüğüne zarar vereceğinden mevcut yerinde 6, 00 metre yükseltilmesine yönelik mimari koruma, yapısal güçlendirme ve yerinde yükseltme uygulaması disiplinler arası bütüncül bir çalışmayla gerçekleştirilmiştir.
Analyzing correlations between approaches to analyzing decision-making styles

Descriptive decision-making theories center on the analysis of individuals' decision-making styles (DMSs). Different approaches have been used to study DMSs, but this study focuses on two approaches: those of (1) Scott & Bruce and (2) Rowe. Scott & Bruce categorizes DMSs into rational, intuitive, dependent, avoidant, and spontaneous, whereas Rowe delineates them into analytical, behavioral, conceptual, and directive. Previous studies have independently used these approaches to identify dominant DMSs or to establish correlations between DMSs and various personal characteristics. In this study, both DMS approaches were concurrently used to examine their correlations. The sample comprised 263 students, and correlation analyses were conducted on the entire dataset and its subsets while considering different characteristics (i.e. students' gender and study program, and the data collection timeframe). Multivariate correlation, along with descriptive statistics, was employed to investigate the correlation between the two approaches. The analysis revealed a positive correlation between the behavioral and dependent styles and a negative correlation between the avoidant and analytical styles. Additionally, the examination of the dominant and submissive styles indicated a significant connection between the analytical and rational DMSs. Overall, the two approaches exhibited weak connectivity. For a more comprehensive understanding of decision-makers' behavior and enhanced predictive capabilities, the concurrent application of the two approaches is imperative.

Published: May 2024

There is a large number of sources devoted to the American style options. On the other hand, the American futures contracts are understudied in the scientific literature. This motivated us to examine these instruments in comparison to the relevant options. Their optimal boundaries are obtained and a finite difference scheme is applied to the pricing problem. We consider separately the long and short positions.
