Published: March 2023

O objetivo do estudo foi analisar a tendência temporal e fatores associados à participação nas aulas de educação física de estudantes de Pernambuco. Estudo de tendência temporal composto por três levantamentos de abrangência estadual. Foram entrevistados 4.207 estudantes em 2006, 6.264 em 2011 e 6.002 em 2016, por meio do questionário “Global School-based Student Health Survey” (GSHS). O desfecho foi a participação nas aulas de Educação Física e as exposições foram as informações sociodemográficas. A análise bivariada foi realizada mediante  teste Qui-quadrado e as análises multivariadas por regressão logística binária. Observou-se um aumento na prevalência de participação nas aulas de Educação Física (2006: 35%, 2011: 74% e 2016: 81,2%) destacando o aumento significativo no sexo masculino Δ% (2006-2016) = 123,5%. Ser do sexo masculino, estudar no período integral e ser filho de mães que estudaram, independente do tempo de estudo foi associado a maior participação nas aulas de educação física, assim como residir nas regiões do Agreste, Sertão e Sertão do São Francisco. Apesar do aumento na participação nas aulas de Educação Física em Pernambuco, a garantia deste componente curricular deve ser fortalecida, levando em consideração os grupos de risco para que aumente a participação nas aulas desses grupos.

A Convex Programming Framework for Information Design Under Realistic Human Behavior

Platform markets and services typically have additional relevant information in comparison with their users. Information design studies how the sharing of this information can be leveraged by the platform to influence user behavior and obtain desirable outcomes. Previous research has studied information design assuming that the users act to maximize their expected utility, but this assumption does not always hold in reality. Instead, people often exhibit biases and deviations from expected utility maximization. In “Persuading Risk-Conscious Agents: A Geometric Approach,” Anunrojwong, Iyer, and Lingenbrink study information design with “risk-conscious” agents whose utility functions may depend nonlinearly on their beliefs. They provide a convex programming approach for solving for the optimal persuasion mechanism and establish their structural properties in different settings. They illustrate their approach in an application involving the sharing of waiting-time information in a queueing system. Overall, this work contributes to the study of information design under realistic models of human behavior.
The Fundamental Recruitment Error: Candidate-Recruiter Discrepancy in Their Relative Valuation of Innate Talent vs. Hard Work
Authors: Dai Xianchi , Si Kao
Published: March 2023

Innate talent and orientation toward hard work are highly important personal attributes with respect to workers’ productive capabilities. In this research, we identify a discrepancy between job candidates and recruiters in their relative valuation of these two attributes. Although innate talent is valued relatively more by job candidates than recruiters, the opposite is true for orientation toward hard work. We propose that the discrepancy is rooted in a misalignment of the fundamental motivations of the two parties in the job market. In seven studies (four preregistered), which include randomized trial experiments and quasi-experiments and use real life recruiters and job seekers (across a total of 112 industries) as participants, we provide evidence of the current effect and its underlying mechanism. Studies 1A–1C demonstrate the negative consequence of the discrepancy on job market efficiency, showing that it can lead candidates to adopt impression management strategies that lower their chance of getting the job. Studies 2A and 2B show that full-time workers consider career potential to be associated with both innate talent and hard work but position performance to be more strongly associated with hard work than innate talent. Finally, Studies 3A and 3B indicate that candidates are relatively more career-focused, whereas recruiters are relatively more position focused and that this difference in their relative focus mediates the current discrepancy. Implications of the present research for both job candidates and recruiters are discussed.

Calibration of spatially modulated snapshot imaging polarimeter based on phase-shift interferometry
Authors: Tang Jinfeng , Jia Chenling , Zhang Jin , Jiang Ming , Pan Yangliu , Jiang Siyue , Hu Baoqing , Cao Qizhi , Jin Mingwu
Published: March 2023

The snapshot imaging polarimeters (SIPs) using spatial modulation have gained increasing popularity due to their capability of obtaining all four Stokes parameters in a single measurement. However, the existing reference beam calibration techniques cannot extract the modulation phase factors of the spatially modulated system. In this paper, a calibration technique based on a phase-shift interference (PSI) theory is proposed to address this issue. The proposed technique can accurately extract and demodulate the modulation phase factors through measuring the reference object at different polarization analyzer orientations and performing a PSI algorithm. Using the snapshot imaging polarimeter with modified Savart polariscopes as an example, the basic principle of the proposed technique is analyzed in detail. Subsequently, the feasibility of this calibration technique was demonstrated by a numerical simulation and a laboratory experiment. This work provides a different perspective for the calibration of a spatially modulated snapshot imaging polarimeter.
Heterogeneous integration of a III–V quantum dot laser on high thermal conductivity silicon carbide
Authors: Koscica Rosalyn , Wan Yating , He William , Kennedy M. J. , Bowers John E.
Published: March 2023

Heat accumulation prevents semiconductor lasers from operating at their full potential. This can be addressed through heterogeneous integration of a III–V laser stack onto non-native substrate materials with high thermal conductivity. Here, we demonstrate III–V quantum dot lasers heterogeneously integrated on silicon carbide (SiC) substrates with high temperature stability. A large T0 of 221 K with a relatively temperature-insensitive operation occurs near room temperature, while lasing is sustained up to 105°C. The SiC platform presents a unique and ideal candidate for realizing monolithic integration of optoelectronics, quantum, and nonlinear photonics.

Published: March 2023

Cr:Colquiriites (Cr:LiCAF, Cr:LiSAF, and Cr:LiSGaF) are well-known for
their broad emission bands in the near-infrared region. Unfortunately,
due to their relatively weak thermomechanical strength, average powers
from Cr:Colquiriite lasers have been so far limited to sub-5 W level
in continuous-wave operation at room temperature. In this study, the
promise of cryogenic operation, which shows significant power
scalability in Yb-based systems, is investigated in detail for
Cr-doped Colquiriite crystals in terms of the temperature dependence
of the fluorescence lifetime and emission cross-section
(σ
e
) in the 78-618
K range. The lifetime measurements showed that the fluorescence, as
well as the radiative lifetimes of Cr:Colquiriites are temperature
dependent. The emission cross-section measurements revealed that while
cooling the crystals from 300 K to 78 K, the peak
σ
e
in
E||c polarization increases moderately for all crystals:
from around 1.3 × 10−20
cm2 to 1.6 × 10−20
cm2 in Cr:LiCAF, from around
4.5 × 10−20 cm2 to
6.3 × 10−20 cm2 in
Cr:LiSAF and from around
3.1 × 10−20 cm2 to
3.95 × 10−20 cm2 in
Cr:LiSGaF. We provide analytical formulas describing the measured
temperature dependence of all relevant quantities such as
fluorescence/radiative lifetime, peak emission wavelength, peak
emission cross-section, and emission full-width at half-maximum.
Overall, the reported results constitute a solid basis for the
modeling of Cr:Colquiriite-based laser and amplifier systems,
especially for the assessment of their potential at cryogenic
temperatures.

Authors: Thummar Ruturaj , Dhadhal Dharmendra , Mishra Vivekanand
Published: March 2023

The ideal way to approach a modern communication system that needs to be improved and used for high data rate transmission is with DWDM. In this study, we employ DWDM communication systems with 64 channels, different data speeds, and a dispersion compensation method. The pulse enlargement effect of transmitted light in the optical fiber is constrained by the dispersion reimbursement approach. DCF brought are simulated, analysed, and done to explore the sixty-four channels DWDM machine using DCF for NRZ modulation format at varied Bit Rate with several energy tiers to resolve the dispersion effect. The suggested method for 10 to 40 Gbps uses an NRZ modulation technique with an erbium doped fibre amplifier (EDFA) over a single mode fibre transmission distance of 40 to 160 km and a dispersion compensation fibre of 8 to 32 km (DCF). The developed model's performance is measured in terms of Quality factor, Bit Error Rate (BER), Eye Height, and Threshold at two input energy levels from an optical power source over the 0.625 Tbps to 2.5 Tbps communication capacity.
Donate Yourself: An AR trail exploring the future of organ, tissue and body data donation
Authors: Pitsillides Stacey , Boddington Ghislaine , VindiŠ Tadej
Published: March 2023

This article explores how communication and interaction design were used in the augmented reality experience, Donate Yourself. It aims to demystify some of the ethical and personal concerns around the donation of organs, tissue and body data for scientific and medical research. The research finds different modes of provoking thought around a central question: can augmented reality be used to open debates on who has access to our biological and digital traces beyond death? Taking into account how COVID-19 has made the public deeply reconsider their biological and data bodies, the paper documents and contextualizes the making of Donate Yourself, which was created in collaboration with interactive design collective body>data>space and scientists from the Human Cell Atlas project (HCA). In doing so, it explores the contested histories of human tissue in research and contemporizes these relations by looking at the way HCA members use and care for human tissue and data in their work. A range of methods that were used to capture diverse public attitudes and ethical concerns about donation using participatory approaches included: the co-creation of design probes with HCA scientists, online workshops, qualitative interviews, a documentation zine and public maker jam. These methodological lenses, and the data they produce, were used to construct a non-linear narrative and digital bricolage that is experienced as a hybrid public walking tour. Five themes were generated for the augmented reality experiences: care, trust, immortal, consent, future. This triangulation of science, technology and the arts was materialized in a webAR walking trail that ran during November 2021, which was accessed by the public via QR codes as part of the larger One Cell At A Time online exhibition, funded by the Wellcome Trust.

Published: March 2023

Background and Aim: In several countries, two Entamoeba porcine species, Entamoeba suis and Entamoeba polecki (subtype 1 and 3), have been detected using molecular methods and identified pathogenicity associated with enteritis. However, globally, Entamoeba infection prevalence in pigs is extremely limited. This study aimed to coprologically and genetically examine pig parasites to estimate prevalence of Entamoeba in three pig farms in East Java, Indonesia.

Materials and Methods: Hundred porcine fecal samples (Landrace) were collected from three East Javan farms in well-known swine industry regions. Fecal samples were examined under microscope after sugar-flotation centrifugation, and molecular species and subtype identification were performed using polymerase chain reaction (PCR) and primer pairs targeting small-subunit ribosomal RNA.

Results: Microscopy examinations identified parasites in 89/100 fecal samples; Entamoeba spp. cysts were the most frequent in these samples. Polymerase chain reaction showed that 58 samples were comprised of mixed Entamoeba suis and Entamoeba polecki, 22 E. suis alone, and nine E. polecki alone infections. Epolec F6–Epolec R6 primers successfully amplified E. polecki ST1–4 subtypes, while Epolecki 1–Epolecki 2 amplified only the E. polecki ST1 subtype. Entamoeba polecki ST1-specific primers successfully detected the ST1 subtype in 19/67 E. polecki positive samples.

Conclusion: Entamoeba spp. prevalence in Indonesian pigs was previously shown to be high. On coprological examination of East Javan pigs, we detected high Entamoeba spp. levels, in which we genetically identified as E. suis (80.0%), E. polecki (67.0%), and E. polecki ST1 (19%).

A Deficiência Auditiva (DA) no recém-nascido pode ocasionar comprometimento em diferentes esferas de sua vida, como por exemplo, no desenvolvimento da linguagem, alterações da fala, comprometimentos educacionais ou emocionais, dentre outros. A identificação das alterações auditivas pode permitir que as famílias recebam informações e apoio, no intuito de evitar atrasos significativos no desenvolvimento da criança com DA. Neste contexto, tem-se a Triagem Auditiva Neonatal, também conhecida como Teste da Orelhinha, que permite a detecção de possíveis alterações auditivas em neolactantes e lactantes, possibilitando o diagnóstico da perda auditiva antes do terceiro mês de vida e a intervenção antes dos seis meses de idade. Para isto, é necessário que se tenha um sistema que possa acompanhar a criança com suspeita de DA, desde a sua triagem. Embora a triagem seja obrigatória por lei, após o Teste da Orelhinha, os dados relativos à criança, acabam se perdendo. A ausência de dados sistematizados não permite uma tomada de decisão dos gestores sobre o assunto. A fim de contribuir com esta problemática, este artigo apresenta uma plataforma web que permite o acompanhamento das crianças com suspeita de DA. Esta ferramenta está em fase de validação e posterior uso experimental em duas maternidades.
Evolution of the Lamellar Pearlite Structure of Rail Steel under Tension
Authors: Aksenova K.V. , Gromov V.E. , Ivanov Yu.F. , Vaschuk E.S. , Porfiriev M.A.
Published: March 2023

In this paper, the properties of rail steel subjected to fracture under uniaxial tension deformation are studied. Mechanical properties of rail steel, defective substructure of lamellar pearlite, and fracture surface of rail steel are investigated using methods of modern physical materials science.

Tensile strength is found to vary from 1247 to 1335 MPa, and the fracture strain of the samples changes from 0.22 to 0.26. The deformation of the rail steel is accompanied by the process of breaking the ferrite plates into fragments by low angle boundaries along with the significant increase in the scalar dislocation density to 7.9-1010 cm-2 (the scalar dislocation density of the original rail steel is 3.2 -1010 cm-2). Also, there is a formation of internal stress fields appearing in the form of bend extinction contours. The sources of stress fields are identified. It is revealed that cementite plates are fractured by cutting and dissolution with subsequent transfer of carbon to ferrite plates by moving dislocations and formation of round-shaped nanodimensional (8.3 nm) round shaped particles of tertiary cementite. It is shown that the dissolution of cementite plates is accompanied by fragmentation (into coherent scattering regions with an average size of 9.3 nm).
Macroscopic Spatio-Temporal Patterns of Localized Plastic Flow Development under Tension of Fe-Cr-Ni Alloys
Authors: Barannikova S.A. , Iskhakova P.V.
Published: March 2023

This study examines the patterns of macroscopic inhomogeneity and localization of plastic flow in Fe-Cr-Ni polycrystals subjected to uniaxial tension. By varying the test temperature, the deformation curves can be altered, allowing us to explore the behavior of the material under different conditions. The stress-strain diagrams obtained from the samples reveal the areas of elastic deformation, plastic flow, and fracture. To experimentally study plastic flow, we used speckle photography to accurately reconstruct the displacement vector fields and calculate the components of the plastic distortion tensor. The results showed that plastic flow is localized at all stages of the process for test temperatures of+65, +24, and -60 °C. The forms oflocalization are entirely determined by the dependence of the strain hardening coefficient on the deformation during the relevant stage of the process. An analysis of the spatial distributions of local shifts and local rotations was conducted. We observed spatially periodic structures that can be interpreted as autowave processes and explained in terms of the concept of self-organization of the plastic flow process.
Deterministic Interpretation of the Malus Law and Correlation in Experiments with Entangled Photons
Authors: Гончаров Александр Иванович
Published: March 2023

This paper examines a local deterministic model of an experiment involving correlated photons. The experimental setup involves a source that emits two linearly polarized photons in each act, two two-channel analyzers, and detectors included in the coincidence scheme. The orientation angle of the photon polarization plane is a random variable with a uniform distribution, and it is the same for simultaneously emitted photons. The model presented here is a generalization of the “naive example of hidden variable theory” described in A. Aspect's article ‘Bell's Theorem: The Naive View of an Experimentalist.

In our model, the outcome of the photon interaction with the analyzer (hit in one of the two channels) is uniquely determined by the angle between the photon polarization plane and the analyzer axis and is described by a step function. The difference in our model is that the step function contains a large number of segments of different lengths. The location and lengths of the segments are set so that the probability of a photon hitting a specific channel of an ideal analyzer, determined by averaging the outcomes over small neighborhoods of angles, approaches the Malus law when the maximum length of a segment decreases. This ensures that the classical model is self-consistent.

When ideal analyzers are used, the absolute value of the correlation coefficient of detector readings mainly does not exceed the values from Aspect's ‘naive example’. However, when analyzers with absorption are used, the calculated correlations for some orientations of the analyzers exceed the quantum mechanical values. Key words: linear polarization of photons, Malus law, entangled photons, correlations, hidden parameters.
Recognition of Synthesized Intermetallic Interlayers at the Interface in Ti@Al "Core — Shell" Nanoparticles Based on Computer Molecular-Dynamic Simulation
Authors: Jordan V.I. , Shmakov I.A.
Published: March 2023

The paper presents the results of applying a new method, previously developed by the authors, based on precalculated sets of 3D distributions of a matter density. The method is designed to recognize the spatial 3D distributions of the synthesized intermetallic compounds in the volume of a nanoparticle. A set of 3D distributions of a matter density in the volume of a cubic Ti@Al core — shell nanoparticle corresponds to a set of successive time points. It is calculated based on the results of the computer molecular dynamics simulation of self-propagating high temperature synthesis in the nanoparticle. Computational experiments are performed using the LAMMPS software package. Based on the obtained results, thermal and microstructural analyses are performed, confirming the multistage mechanism for the formation of intermetallic phases during the SHS reaction in the Ti-Al reaction medium. The sets of 3D distributions of the matter density and 3D distributions of synthesized intermetallic compounds in the volume of a nanoparticle corresponding to the sequence of time points are calculated. The paper shows the advantage of the method for recognizing 3D distributions of synthesized intermetallic compounds, proposed by the authors, over the methods of similar analysis built into the OVITO software package.
On the Geometry of Almost Quasi-Para-Sasakian Manifolds Equipped with a Canonical N-Connection
Authors: Galaev S.V. , Kokin E.A.
Published: March 2023

This paper introduces the concept of an almost quasi-para-Sasakian manifold, which differs from the previously known quasi-para-Sasakian structure in that it is not a normal structure. Instead, it possesses a weaker property called almost normality, similar in properties to integrable tensor structures. Several examples are given, including an almost quasi-para-Sasakian structure defined on the distribution of zero curvature of a sub-Riemanni-an manifold of contact type.

An extended connection with skew-symmetric torsion is defined on an almost quasi-para-Sasakian manifold, which is unique and defined using an intrinsic connection and an endomorphism that preserves the distribution of an almost (para-)contact manifold. The paper proves that the extended connection is a metric connection, and it is also demonstrated that an almost quasi-para-Sasakian manifold can be an n-Einstein manifold with respect to an extended connection with skew-symmetric torsion, provided certain conditions are met.
Cluster Partitions Optimization Using the Latent Class Analysis Technique
Authors: Dronov S.V.
Published: March 2023

The paper explores the formation of a cluster partition using a system of bundles of vectors. Each object is represented by a vector with coordinates corresponding to its characteristic factors. The study focuses on the principles of changes in the total density of these bundles when objects move from one cluster to another. Based on the findings, an algorithm is proposed to reduce the total intracluster variance of the initial cluster partition.

The proposed algorithm is based on a modern technique for analyzing latent classes. This technique emphasizes that the forming factors of objects within each cluster should be highly correlated. Since the number of forming factors is arbitrary, the algorithm replaces this requirement with the maximum possible proximity of object factor vectors to the average vector within each cluster. The degree of this closeness is referred to as the tightness of the cluster vector bundle.

The paper also introduces a new method for quantifying clusters in the improvable clustering constructed using the proposed algorithm. A practical example of the algorithm's application to process medical data is presented. The study discusses the reasons for the dependence of the algorithm's outcome on the choice of initial cluster partition.
Eigenvalues of Ricci Operator of Four-Dimensional Locally Homogeneous Riemannian Manifolds with Nontrivial Isotropy Subgroup
Authors: Klepikov P.N. , Rodionov E.D.
Published: March 2023

The topology of Riemannian manifolds can be linked to the eigenvalues of curvature operators, which was demonstrated in the works of J. Milnor, V.N. Berestovsky, V.V. Slavkii, E.D. Rodionov, and Yu.G. Nikonorov. J. Milnor studied the eigenvalues of the Ricci curvature operator of left-invariant Riemannian metrics on Lie groups, and identified possible signatures of the Ricci operator for three-dimensional Lie groups. O. Kowalski and S. Nikcevic later resolved the problem of prescribed spectrum values of the Ricci operator on three-dimensional metric Lie groups and Riemannian locally homogeneous spaces. D.N. Oskorbin, E.D. Rodionov, and O.P. Khomova also obtained similar results for the one-dimensional curvature operator and the sectional curvature operator. A.G. Kremlev and Yu.G. Nikonorov investigated the fourdimensional case and studied the possible signatures of the Ricci curvature of left-invariant Riemannian metrics on Lie groups. In this study, we aim to solve the problem of prescribed eigenvalues of the Ricci operator on locally homogeneous Riemannian manifolds with a nontrivial isotropy subgroup.
A Criterion for Mapping Homogeneity
Authors: Polikanova I.V.
Published: March 2023

The paper proposes a definition of a homogeneous mapping based on the concept of a group action. This definition can be used to describe generalizations of the concept of "homogeneous function," including positive, absolute, limited homogeneity, lambda-homogeneity, and homogeneous distributions. The main result is as follows: if a group acts on the set of assignments and values of the mapping, and acts commutatively on the set of values, then the mapping is homogeneous with respect to these actions if and only if the homogeneity condition is satisfied for the generating set of this group.

In most cases, the assignment sets and value sets of mappings are vector spaces, and the multiplicative group of the main field or its subgroup acts as an acting group. Therefore, it is important to know their generating sets. For example, for the multiplicative group R+ of positive real numbers, these are numerical intervals, possibly with excluded null sets. Thus, it follows that the homogeneity of a function, understood traditionally, is guaranteed by the fulfillment of the homogeneity condition for any numerical interval from R+. This fact was previously only established for differentiable functions using the well-known Euler identity for homogeneous functions.
Symmetric Ricci Flows of Semisymmetric Connections on Three-Dimensional Metrical Lie Groups: An Analysis
Authors: Khromova O.P. , Balashchenko V.V.
Published: March 2023

The study of Ricci flows, which describe the deformation of (pseudo) Riemannian metrics on a manifold, and their solutions, Ricci solitons, has garnered much attention from mathematicians. However, previous studies have typically focused on manifolds with Levi-Civita connections. This paper breaks new ground by considering manifolds with semisymmetric connections, which also include the Levi-Civita connection. Metric connections with vector torsion, or semisymmetric connections, were first studied by E. Cartan on (pseudo) Riemannian manifolds. Later, K. Yano and I. Agricola studied tensor fields and geodesic lines of such connections, while P.N. Klepikov,

E.D. Rodionov, and O.P. Khromova considered the Einstein equation of semisymmetric connections on three-dimensional locally homogeneous (pseudo) Riemannian manifolds. Because the Ricci tensor of a semisymmetric connection is not symmetric in general, we focus on studying the symmetric and skew-symmetric parts of the Ricci tensor. Specifically, we investigate symmetric Ricci flows on three-dimensional Lie groups with J. Milnor's left-invariant (pseudo) Riemannian metric and E. Cartan's semisymmetric connection.

Prediction of the output power of photovoltaic module using artificial neural networks model with optimizing the neurons number
Authors: Mohammad Abdulrahman Th. , Hussen Hasanen M. , Akeiber Hussein J.
Published: March 2023

Artificial neural networks (ANNs) is an adaptive system that has the ability to predict the relationship between the input and output parameters without defining the physical and operation conditions. In this study, some queries about using ANN methodology are simply clarified especially about the neurons number and their relationship with input and output parameters. In addition, two ANN models are developed using MATLAB code to predict the power production of a polycrystalline PV module in the real weather conditions of Iraq. The ANN models are then used to optimize the neurons number in the hidden layers. The capability of ANN models has been tested under the impact of several weather and operational parameters. In this regard, six variables are used as input parameters including ambient temperature, solar irradiance and wind speed (the weather conditions), and module temperature, short circuit current and open circuit voltage (the characteristics of PV module). According to the performance analysis of ANN models, the optimal neurons number is 15 neurons in single hidden layer with minimum Root Mean Squared Error (RMSE) of 2.76% and 10 neurons in double hidden layers with RMSE of 1.97%.  Accordingly, it can be concluded that the double hidden layers introduce a higher accuracy than the single hidden layer. Moreover, the ANN model has proven its accuracy in predicting the current and voltage of PV module.

Rola czasopism „Червоний шлях” i „Життя й революція” w procesie tworzenia ukraińskiej translatologii w latach 20 i 30. XХ wieku
Authors: Rysicz-Szafraniec Julia
Published: March 2023

Artykuł porusza zagadnienia z historii ukraińskiej translatologii, mianowicie roz- woju tej nauki w zakresie teorii, praktyki oraz krytyki przekładu w latach 20. i 30. XX stulecia. Główną hipotezą rozprawy jest twierdzenie o znaczącej roli czasopism w procesie stanowienia ukraińskiej translatologii jako nauki. W tym celu przeanalizowano krytyczne i teoretyczne teksty, które ukazały się na łamach miesięczników „Червоний шлях” (1923–1936) i „Життя й революція” (1925–1934) oraz podliczono opublikowane w nich przekłady tekstów literackich. W wyniku badań wyłoniły się kolejne perspektywistyczne wątki badań nad zawartym w danych źródłach materiałem przekładoznawczym.
Koncepcja Iwana Franki dotycząca pochodzenia paremii: przejście międzygatunkowe
Authors: Szymkiw Jaryna
Published: March 2023

W artykule została przeanalizowana geneza przysłów i porzekadeł – jedno z naj- mniej zbadanych zagadnień paremiologii. Podkreślono, że przedstawiony problem rzadko pojawia się w polu naukowych zainteresowań folklorystów ukraińskich i zagranicznych. Jednak największy wkład w rozwiązanie tajemnicy pochodzenia paremii miał Iwan Franko, który w podstawowym trzy- tomowym korpusie Galicyjsko-ruskie przypowieści ludowe (ukr. Галицько-руські народні приповідки) najpełniej przedstawił sposoby uzupełniania funduszu przysłów. Według koncepcji badacza jednym z najbardziej wydajnych sposobów jest tzw. przejście międzygatunkowe, kiedy obszerniejsze gatunki zostają zredukowane do lakonicznej formuły słownej przypowieści (ukr. приповідки). Praca ujawnia, że Iwan Franko udowodnił ścisłe połączenie przysłów i porzekadeł z dowcipem, baśnią i opowiada- niem ludowym. Na podstawie konkretnych przykładów odzwierciedla się trudną pracę analityczną, jaką wykonał autor zbioru aforyzmów ludowych, starając się prześledzić pochodzenie każdego egzem- plarza. Dzięki systematycznej pracy Iwana Franki w zakresie genezy paremii udało się uwypuklić ten aspekt badań folklorystycznych na nowym poziomie i potwierdzać ścisłe korelacje międzygatunkowe, poprzez które ujawnia się niewidzialna substancja mądrości ludowej.
„Wszelka inność – wewnątrz”: problem niepełnosprawności w powieści "(Nie)widzialni" Iwana Bajdaka
Authors: Hajduk Switłana
Published: March 2023

Artykuł poświęcony jest problematyce osób z niepełnosprawnością we współczesnej literaturze ukraińskiej. Celem artykułu jest zwrócenie uwagi na specyfikę ujęcia problemu Innego, w szczególności osoby z zespołem Tourette’a, obecnej w powieści (Nie)widzialni współczesnego ukra- ińskiego pisarza Iwana Bajdaka. Zaakcentowano bezpośredni związek niepełnosprawności (zespołu Tourette’a) autora z jego powieścią. Zauważono, że obecność w powieści bohaterów z niepełnospraw- nością nacechowana jest kondycją fizyczną samego autora, który przy ich pomocy stara się nie tylko demonstrować własne wartości i wytyczne, lecz także skłaniać ludzi i społeczeństwo do akceptacji Innego jako odmiennego. Wszakże pragnienie zrozumienia, miłości i wsparcia osób z niepełnospraw- nością napotyka trudności z powodu stereotypów w społeczeństwie, w którym często nie ma miejsca dla głównego bohatera Adama, ponieważ dla ludzi pozostaje on Innym, Obcym lub, jak pisze autor na początku powieści, „Nie takim”. Ponadto powieść ma pomóc osobom niepełnosprawnym zrozu- mieć siebie i Innych, a co najważniejsze, zaakceptować swoją wyjątkowość i nauczyć się siebie kochać.
Investigation into a multiple input/output bifurcated biochemical reaction with substrate inhibition in a real CSTR based on Cholette’s model
Authors: Yang Chane-Yuan , Tsai Ding-Chi , Chien Yu-Shu
Published: March 2023

CSTR operations entailing high nonlinearity and complexity such as multiple input and output steady-states present a real challenge to chemical engineers and process designers. The input multiplicity in chemical reactions leads to control probems such as process instability and low efficiency. Therefore, it is of critical importance to predict and avoid the multiplicity regions during reactor operation. Since the bifurcation analysis of biochemical processes with nonideal mixing has been carried out by the authors in the previous publication (Yang, C. Y., D. C. Tsai, and Y. S. Chien. 2021. “The Strategy Developed for High Conversion and the Multiplicity Problems of Biochemical Reaction in a Real CSTR with Cholette’s Model.” International Journal of Chemical Reactor Engineering 19: 1245–70), the goal of the present work is to use Sturm’s method, Routh stability criteria and the discriminator roots method with the tangent analysis method to derive the input multiplicity conditions in substrate inhibition in a real CSTR based on Chollete’s model. Four kinetic schemes are used in the analysis as examples to show that all three methods can precisely obtain the bifurcation starting point for the input multiplicity. In addition to the multiple input steady-states, the start-up diagram obtained by the discriminator root method is of critical importance to avoid operating in the input multiplicity regions.
