Low-frequency passive seismic (LFPS), discussed in recent years, has emphasized a strong correlation between the spectral properties and the presence of hydrocarbon reservoirs. While the theoretical background supporting this phenomenon is still debated, its application has been popular in Indonesia and exposes broad possibilities for exploration. In this study, we conducted a survey at an oil field in Central Java, Indonesia, investigating the case of using this technique as a direct hydrocarbon indicator (DHI). In spatial and temporal measurements, we examined the hydrocarbon-related energy above the reservoir boundary based on several attributes of passive seismic recordings: polarization, power spectral density (PSD), and vertical-to-horizontal spectral ratio (VHSR). We address some issues: (1) the anomalies are not always vertically polarized, so the use of VHSR is unlikely to be reliable; and (2) the anomalies are getting amplified during days, so in anomalies mapping, normalizing the amplification requires calibration. Regardless, LFPS is still applicable in quantifying hydrocarbon-related energy. We recommend using PSD as a primary spectral attribute for DHI. In addition, it is also critical to synchronize the measurements at different sites to obtain an unbiased quantification of hydrocarbon-related energy.
Little Samaritan Brothers: Crowdsourcing Voter Surveillance
Authors: Ben-David Anat
Published: January 2024

Voter surveillance for digital campaigning is perceived as enacted from above. Political parties are “all-seeing actors” combining access to the Voters’ Registry with digital tools to maximize voter turnout. At the same time, new forms of lateral surveillance emerge as citizens voluntarily participate in the data collection process to help political parties achieve their electoral goals. This article examines the reconfiguration of the concepts of crowdsourcing and political participation through the use of voter-surveillance applications. Theoretically, it explores how crowdsourced voter surveillance (CVS) builds on the emancipatory rhetoric of political participation and crowdsourcing while relying on social, technical, and political surveillance infrastructures. Empirically, it maps the information flows and knowledge hierarchies afforded by Elector, a CVS app used by the Likud party in the Israeli election of March 2020. The findings indicate that contrary to the logic of crowdsourcing as democratizing knowledge and participation, CVS cultivates controlled individuals and normalizes lateral surveillance as a ritualistic and desired form of political participation. The article therefore describes the type of political action that CVS constructs as Little Samaritan Brothers: citizens who collectively resign their rights and the rights of their peers for the party’s success.
Radiative cooling: arising from practice and in turn serving practice
Authors: Zhang Quan , Rao Zhonghao , Ma Rujun
Published: January 2024

Radiative cooling, as a renewable cooling technology, is expected to mitigate growing global warming. However, the barrier when promoting radiative cooling from the laboratory to practice is still a blind spot and needs to be discussed right now. Here, on the basis of review for brief history, we propose a developing thread that the studies on radiative cooling arise from practice and in turn serves practice at the end. This perspective orderly elaborates fundamental limit in theory, realization of spectral-selective materials, practice on criteria for cooling performance, challenges and corresponding possible solutions in practice, and focusing on serving practice. We hope that the criticism for our own opinion could trigger researchers to deeply consider how to make achievement of radiative cooling better serving practice in the future.
Predictors of diagnosed cardiovascular diseases and their spatial heterogeneity in Lagos State, Nigeria
Authors: Addie Oluwaseun , John Taiwo Olalekan
Published: January 2024

Cardiovascular diseases (CVDs) persist as the foremost global cause of death despite persistent efforts to comprehend the risk factors associated with them. Low- and middle-income countries (LMICs) are disproportionately affected, bearing a high burden of CVD morbidity and mortality. Nevertheless, the intricate socio-spatial landscape that could yield new insights into CVD incidence within LMICs like Nigeria has not received sufficient attention. This study aimed to determine the predictors of CVDs in a megacity in one of the LMICs and investigate their spatial heterogeneity. The study acquired and appropriately geocoded hospital records of patients clinically diagnosed with CVDs between 2008 and 2018 from a tertiary healthcare facility. Stepwise regression and geographically weighted regression were employed to identify predictors of CVDs and investigate their patterns. The study’s findings revealed that gender emerged as the primary predictor of diagnosed CVDs. Consequently, the study underscores the importance of focusing on the female population in efforts to control and prevent CVDs while advocating for the formulation and implementation of spatially sensitive policies and interventions.

Authors: Alshehry Azzh Saad , Yasmin Humaira , Khammash Ahmed A. , Shah Rasool
Published: January 2024

This study demonstrates the use of fractional calculus in the field of epidemiology, specifically in relation to dengue illness. Using noninteger order integrals and derivatives, a novel model is created to examine the impact of temperature on the transmission of the vector–host disease, dengue. A comprehensive strategy is proposed and illustrated, drawing inspiration from the first dengue epidemic recorded in 2009 in Cape Verde. The model utilizes a fractional-order derivative, which has recently acquired popularity for its adaptability in addressing a wide variety of applicable problems and exponential kernel. A fixed point method of Krasnoselskii and Banach is used to determine the main findings. The semi-analytical results are then investigated using iterative techniques such as Laplace-Adomian decomposition method. Computational models are utilized to support analytical experiments and enhance the credibility of the results. These models are useful for simulating and validating the effect of temperature on the complex dynamics of the vector–host interaction during dengue outbreaks. It is essential to note that the research draws on dengue outbreak studies conducted in various geographic regions, thereby providing a broader perspective and validating the findings generally. This study not only demonstrates a novel application of fractional calculus in epidemiology but also casts light on the complex relationship between temperature and the dynamics of dengue transmission. The obtained results serve as a foundation for enhancing our understanding of the complex interaction between environmental factors and infectious diseases, leading the way for enhanced prevention and control strategies to combat global dengue outbreaks.

Published: January 2024

The corrosion process of Q345 steel in simulated industrial atmospheric surroundings using NaHSO3 as the corrosion medium was performed. Corrosion weight loss, X-ray diffraction (XRD), electron probe microanalysis (EPMA), laser scanning confocal microscopy (LSCM), and scanning electron microscopy (SEM) were utilized to investigate the corrosion behavior of Q345 steel samples at various corrosion times. The results indicate that, in the industrial atmospheric acceleration system, the corrosion law of Q345 steel follows an exponential function model and that as the corrosion period lengthens, the rate of corrosion declines steadily. γ-FeOOH, α-FeOOH, Fe3O4, Fe3O2, and FeO make up the majority of the corrosion products on the surface of rust layer, and the rust layer structure is generally loose in the first stages of corrosion. As the corrosion time lengthens, the corrosion products transform from needle-like to cluster-like and the rust layer will become thicker. In addition, there is a segregation of the elements Cr, S, and O in the rust layer of Q345 steel.
Study on the properties of branched-chain alkyl glycoside nonionic surfactant and anionic surfactant in a mixed system
Authors: Li Jiahao , Bai Liang , Yang Xiuquan , Qi Yunqin , Zhou Yuan , Wu Zhiyu , Qin Ziyu
Published: January 2024

The surface activity, intermolecular interactions and thermodynamic parameters of a mixture of a nonionic surfactant (branched-chain alkyl glycoside (IG-10)) and an anionic surfactant (alcohol ether carboxylic acid (90H)) were investigated and the wetting, emulsifying and foaming properties of the mixed system were also evaluated. The results show that there is a mutual attraction at the mixed micelles and gas/liquid interfaces formed by the two surfactants. The thermodynamic parameters show that the formation of mixed micelles from two different surfactants is a non-ideal process. In terms of application performance, the wetting ability and foaming properties of the mixed system showed good synergistic effects, with the wetting time of the mixed system being shorter than that of the two single surfactant systems and the foam stability being weaker than that of the single system. The best emulsifying capacity was obtained when the mass fraction of 90H was 50 %.

Authors: Brûlé Emilie , Zhou Xiang , Wang Ying , Buddle Evan R S , Ongaro Luisina , Loka Mary , Boelen Anita , Bernard Daniel J
Published: January 2024

Objective

Loss of function mutations in the insulin receptor substrate 4 (IRS4) gene cause a rare form of X-linked congenital central hypothyroidism in boys and men. Affected individuals show decreased thyroid-stimulating hormone (TSH) secretion. Members of the IRS family canonically act as scaffold proteins between tyrosine kinase receptors and downstream effectors. How loss of IRS4 affects TSH synthesis or secretion is unresolved. We therefore assessed IRS4’s role in the hypothalamic–pituitary–thyroid axis of Irs4 knockout mice.

Methods

We generated two global Irs4 knockout mouse lines harboring either two or four base-pair deletions that result in frameshifts and loss of most of the IRS4 protein.

Results

Under normal laboratory conditions, Irs4 knockout males did not exhibit impairments in pituitary expression of TSH subunit genes (Tshb or Cga) or in the thyrotropin-releasing hormone (TRH) receptor. Additionally, their serum thyroid hormone, triiodothyronine (T3) and thyroxine (T4), and hypothalamic Trh expression levels were normal. When Irs4 knockouts were rendered hypothyroid with a low-iodine diet supplemented with propylthiouracil for 3 weeks, their serum TSH increased similarly to wild-type males.

Conclusion

Overall, Irs4 knockout mice do not exhibit central hypothyroidism or otherwise appear to phenocopy IRS4 deficient patients. Compensation by another IRS protein may explain euthyroidism in these animals.

Published: January 2024

Malgré la richesse de la littérature consacrée à “La Chanson de Roland”, les recherches sur le style du poème ne sont pas nombreuses.Le but de ce travail est de définir et d’analyser un de ses procédés stylistiques et notamment l’épithète. Ainsi, du point de vue linguistique et stylistique nous considérons l’épithète comme une unité syntaxique d’attribution, de prédication, d’apposition à valeur affective qui sert à caractériser les personnes et les choses dans l’oeuvre littéraire. Selon leur valeur expressive on peut les diviser en groupes. Nous avons choisi la classification de A. Véselovski qui est basée sur les oeuvres épiques. L’auteur distingue deux groupes d’épithètes: les épithètes tautologiques et les épithètes explicatives (ce dernier groupe est plus intéressant du point de vue linguistique et stylistique). L’analyse de l’épithète de “la Chanson de Roland” a prouvé encore une fois l’interdépendance et la corrélation de tous les procédés stylistiques dans l’oeuvre littéraire où l’épithète est l’un des moyens d’expression à valeur affective.
Der lit. Flussname Nemunas und das lit. namas “Haus” (Einige Bemerkungen zur Etymologie)
Authors: Balaišis Vytautas
Published: January 2024

Straipsnyje parodoma, kad K. Būgos Nemuno etimologija patikimiausia. Nemuno vardas vedamas iš lyties *nemus. Ji sietina su lot. nemus “krūmas, šilas, šakos, ganykla, medis”. Bandoma parodyti, kad kilmės atžvilgiu Nemunas nėra pelkinė upė, kaip nurodoma Pokorny žodyne, bet šilo upė.Siūloma namo etimologiją kildinti iš tos pačios lyties kaip ir Nemunas – iš *nemus. J. Endzelyno hipotezė, pagal kurią namas kilęs iš *damas, įvykus disimiliacijai junginyje *damą daryti, laikoma abejotina. Pirminė idc. šaknies *dom- reikšmė buvo ne namas, bet socialinė žmonių struktūra ir jos santykis su šeimininku (plg. gr. despotis “namų šeimininkas”). Vėliau *dom- reikšmė buvo išplėsta žemei, namo vietai ir apskritai namui žymėti. Lietuvių kalbos žodžiai dimstis, apydėmė atspindi pirminę idc. *dam- reikšmę. Baltai susikūrė naują žodį, pavadindami namą pagal statomą medžiagą (šakos, medžiai – nemus).Nemunas ir namas yra kilę iš tos pačios idc. šaknies *nem-, kuri yra daugiareikšmė. Viena iš reikšmių yra “imti” (plg. lat. nemt, vok. nehmen). Imti tai reiškia gauti iš gamtos naudą, skinant šakas bei lapus – nemus. Tai viena iš seniausių reikšmių. Nemunas yra šilais, krūmais tekanti upė (Būga), o namas būtų iš šakų pastatyta pirmykštė pastogė.

Синтаксическая модель NVN2 prep. N3 как средство выражения посессивнocти
Authors: Григалюнене Йоне
Published: January 2024

The purpose of this paper is to propose an analysis for the construction NVN2 prep. N3 which may be called possessive because a part-whole relation is necessarily implied between N2 and N3. An attempt is made to specify the circumstances under which the subject of the action (expressed by the of touching) coming into contact with a part of an object may be said to be contacting with the whole of it.The present paper also touches upon the problem of the notion of object. At present there is no adequate linguistic theory of object. We propose an interpretation according to which the grammatical object in the construction discussed is regarded as the true object of the action and therefore it cannot be considered irrelevant to “deep syntax”.An attempt has been made here to revise and enlarge the list of verbs used in the said construction.
Cancellous bone tissue remodelling: mathematical modelling
Authors:   Perm National Research Polytechnic University, Kichenko Alexander
Published: January 2024

Bone tissue is a heterogeneous, anisotropic material and consists of compact and cancellous bone tissues. The structure of cancellous bone tissue in different parts of the skeleton is not the same. It conforms to Wolff’s law: it aims to become optimal for the loading which acts on the corresponding bone; the bone remodelling by means of osteosynthesis and resorption mechanisms. The modern problems of biomechanics demand research of the history of formation of bone structures in the course of time at both physiological and pathological loadings. The mandible is one of the most liable to external and internal bone changes. It is liable to physiological changes that occur during the ontogenesis of the organism. Very often, one has to deal with pathological changes caused by incorrect loading of different regions of bone tissue due to dysfunction of a dentition, a temporomandibular joint and so on. For example, the Popov–Godon’s syndrome which connects with tooth loss is accompanied by pathological remodelling of the surrounding bone tissue. Thus, the mathematical modelling of the cancellous bone tissue behavior in the human maxillodental system is one of the topical problems of biomechanics and medicine. Structural features of cancellous bone tissue can be described by means of the fabric tensor. This is possible to implement if there is both a constitutive relation which connects the stress tensor, the fabric tensor, and the strain tensor, and kinetic equations which describe the evolution of the fabric tensor and bone density. The phenomenological Cowin’s equations are chosen and analyzed in detail as such ones. An initial boundary value problem of the cancellous bone tissue remodelling is stated. The solution of this problem allows us to trace changes in the stress-strain state at the trabecular structure formation according to Wolff’s law. The effective numerical algorithm allows us to solve the problem is developed. This algorithm is implemented as a complex of problem-oriented programs. Verification of the model and identification of its parameters are carried out. All numerical calculations are performed using the ANSYS software. Trabecular bone tissue evolution is demonstrated on the set of model examples when the stress–strain state is changed. The results demonstrate different character of influence of changes of loading conditions on the process of structure formation, which follows from Wolff’s law.

The main objective of the research was to study the stress-strain state in biotechnical systems formed in the performance of corrective osteotomies of the first metatarsal bone. The hallux valgus is a common pathology in humans. The incidence of this pathology in females is up to 64 and 25% – in males. Surgical reconstructive treatment remains an urgent problem in modern orthopedics. The situation is caused by unsatisfactory results of treatment. In addition, there is a question about the admissibility of the load in the early postoperative period in patients with quantitative individual assessment. This assessment can be performed using biomechanics. The paper presents methodology for assessing the bone-screw system when performing corrective osteotomies of the first metatarsal bone based on biomechanical methods. The technique allows us to perform a comparative analysis of various methods of osteotomy for a particular patient. In this study, Chevron and Scarf osteotomy with displacement of bone fragments by 1/3 and 2/3 with different variants of their fixation were examined. To solve this problem, personalized geometric models of the first metatarsal bone were built on the basis of computed tomography data using 3D Slicer and SolidWorks systems. Also models of implants were built. The finite element analysis was carried out in the Ansys Workbench software. The focus was on analyzing the stresses that occur on the plantar surface of the first metatarsal bone head during walking. An assessment of the maximum allowable shear of bone fragments for the normalization of deformities of the forefoot was carried out. The developed technique allows us the choice of an osteotomy variant with the justification of the possibility of simultaneous surgery on both feet for a particular patient.
Effects of cement thickness joint of the transdental implant with the tooth tissue on its adhesion properties. Numerical-experimental study
Authors:   Lomonosov Moscow State University, Dzhalalova Margarita , Stepanov Alexander ,   A.I. Evdokimov Moscow State Medical Stomatologic University
Published: January 2024

In previous experimental investigations, adhesion strength was studied with a static tensile load of dental cement joints of an individual milled transdental implant with hard tissues of the tooth root. At the second stage, the effect of artificially formed roughness of the implant surface on the adhesive properties of the cement joint implant– tooth was studied. The implants were sandblasted with alumina pellets of sizes 50, 150, 250 microns – the artificial roughness was the best when processed with granules of 250 microns. In the present work, the next stage of research is presented – the effect of the thickness of the cement joint “transdental implant – cement – dentin tooth” on its adhesive properties. Before milling samples of transdental implants on a digital model, the intra-root part of the implant was reduced by 20, 50, and 100 μm, sandblasted with alumina powder of 250 μm grain and fixed to a removed tooth on cements that have worked best in previous studies. All tests were carried out on an Instron 5900 experimental setup. Zirconia implants were considered in combination with the two most effective cements Fuji-1 and Multilink-N (with the highest adhesion-strength characteristics). As a result of experiments, the combination of zirconia material with Fuji-1 cement turned out to be much better than with Multilink-N cement. A computer simulation of the process of drawing a prototype of a zirconium implant from a tooth root sample with different thicknesses of cement film: 20, 50 and 100 μm was carried out. A satisfactory qualitative and quantitative agreement was obtained between the results of three-dimensional numerical analysis and experiment: with a decrease in the thickness of the cement film from 100 to 20 μm, an improvement in the properties of the adhesive compound is observed, and a thickness of 50 μm can be considered optimal.

There is no doubt that the mechanical effect on the so-called bioactive points and areas may be extremely useful and leads sometimes to a complete cure for various ailments. The existence and benefits of a reflex therapy are absolutely indisputable. Indeed, from ancient times to the present, the unique experience and empirical knowledge about the meridians connecting the points of influence and the skin with all body systems have been accumulated in the depths of Eastern medicine. Until now, the physical nature of the meridians is unknown and has not been explained by anyone, that’s why the reflex therapy stands apart from standard medicine and is practiced as a semi-legal occupation, despite its obvious benefits and effectiveness. In this paper, an attempt was made to reveal the physical nature of the meridians and, thereby, legalize this ancient and extremely necessary discipline. The authors propose a coherent hypothesis, the main idea of which is the statement that if there is even a slightest wound, the nervous system will immediately send the impulse to increase the blood supply to this spot, in other words, a special address appears, the fresh blood directs that way and causes the healing. The mechanism of redistribution of blood flow is that there is a certain low-frequency modulation of the heart rate, which leads to a local increase in blood flow, as impact zones are characterized by certain reductions in time with the modulations. The corresponding organ in the body also has a similar address (i.e. a certain frequency), and therefore an intensified blood flow rushes there too, providing a vital effect on this organ. As a result, the supported organ more effectively fights the disease. This, in short, is the mechanism of recovery that nature has in place in the presence of heart rhythm modulations that can be made manageable. Naturally, by saturating the blood with exposure agents, we will obtain an increase in their effectiveness due to local penetration directly into the painful area.

Published: January 2024

It is often impracticable to employ safety-valves for the protection of pressure vessels used for chemical processing. The bursting disc or rupture diaphragm, a dome of metal foil which will burst when the safe working pressure of a vessel is exceeded, is a particularly suitable form of safety device for process equipment. To function effectively, however, the foil disc must possess a combination of chemical und metallurgical properties which for some purposes only the platinum metals can provide. The selection and use of these metals for bursting discs is discussed in this article.

MODELING OF THREE-LAYER FLOWS WITH NON-UNIFORM EVAPORATION BASED ON THE EXACT SOLUTION OF CONVECTION EQUATIONS
Authors: Laskovets Ekaterina V.
Published: January 2024

Mathematical modeling of three-layer convective flows of two liquids and a gas-vapor mixture in a horizontal channel is based on the exact solution of the Navier-Stokes equations in the Boussinesq approximation. Thermocapillary interfaces are assumed to be non-deformable. The inhomogeneous mass transfer of the light liquid to the upper layer is considered. The Soret and Dufour effects are taken into account in the upper layer, and the gas flow rate is given. The influence of thermal load and flow geometry on the main characteristics of the flow was studied using the example of the waterâbenzineâair system. It is shown that the Soret effect has an impact on the nature of the flow. The influence of the effect of thermodiffusion, changes in the longitudinal temperature gradients, and thicknesses of the layers of the system on the dew point is revealed.
Some issues about the behaviour of external pre-stressed steel–concrete composite beams
Authors: Moscoso Alvaro Wayar , Tamayo Jorge Palomino , dos Santos Sánchez Bárbara , Morsch Inácio Benvegnu
Published: January 2024

A numerical experiment is performed to evaluate the behaviour of externally pre-stressed steel–concrete composite beams (EPSCCBs) up to their ultimate stages, considering second-order effects, tendon material and friction at tendon–deviator locations. The tendon force evolution with loading and slip at the steel–concrete interface is explored. A three-dimensional finite-element model is used to include all these aspects. The idea is to deconstruct the project of eight experimental EPSCCBs with different tendon profiles, considering the above-mentioned issues. The main findings indicate that the inclusion of second-order effects is essential for predicting the stress paths near the collapse loads and slip demands at the steel–concrete interface, while external tendons made of carbon fibre-reinforced polymer (CFRP) can be used as a substitute for classical steel ones, as they presented similar behaviours. The largest tendon force increments occurred for the CFRP tendons compared to other tendons made of glass, aramid and basalt fibre-reinforced polymers. Furthermore, it was found that a friction coefficient between 0.2 and 0.4 at the tendon–deviator interface better matches the available experimental tendon force evolution with loading. This finding seems to counteract the common assumption of using a null friction coefficient as suggested in other works.
From the history of the Society for the Promotion of Regional Culture 1932–1939
Authors: Dziwoki Julia
Published: January 2024

The first period of the activity of the Society for the Promotion of Regional Culture in Częstochowa was the time of a huge work done and the implementation of all the assumptions of the Founding Meeting. We managed to create the Museum of Regional Collections, inspire others to collect monuments and protect the fauna and flora of the Częstochowa region. Most importantly, the periodical publishing house “Ziemia Częstochowska” was initiated, which fills the gap and becomes a contribution to the preparation of the Encyclopedia of Częstochowa. Such active activity of the Society was interrupted first by the death of the president, Wacław Płodowski, and then by the outbreak of World War II on September 1, 1939, which forced the Board to suspend its activities. It seems, however, that the research directions set out in the Foreword by Kazimierz Kühn to the first volume of Częstochowa Land, as in the spiritual testament, are still being implemented.

Including common motives, themes related to presenting the intricate fate of a man who is situated in a closed space that is unreal. The determinant of the work of both artists is the grotesque, and the aesthetics of ugliness associated with it. The examples presented are to reveal the current correspondence of the works of the Sanok artist with the work of Witkacy.
Education of Physics Teachers in Częstochowa – from Teaching Study to the University
Authors: Głowacki Marian
Published: January 2024

The following paper presents evolution of physics teachers’ education in Częstochowa on consecutive academies. The first one is half-high Teaching Study, focused on training physics teachers for elementary schools. Next consecutive academies, preparing physics teachers for primary and high schools at university level, are Higher Teaching School, Higher School of Education. Jan Długosz Academy and Jan Długosz University in Częstochowa. Education mode for teachers is constituted by school system and the place teaching physics takes in it; that is why we start with historical draft of school system after 1945, and then consequent education forms in Poland and Częstohowa, as well as physics teachers’ education from Teaching Study to Jan Długosz University in Częstochowa.

Archives of the Congregation of Propaganda Fide in Rome
Authors: Kopiec Jan
Published: January 2024

The documentation resources of the offices of the Holy See are not only among the most abundant, but their importance is linked to their wide resonance in the overall activity of the papacy. Almost from the beginning of the living activity of the Church, all documents were highly valued in the papal center The papal chancellery, which collects received-but also issues-many documents, was for centuries under the special care of designated papal officials. Above all, the purpose of this care was the documentary value of the various privileges and concessions granted by the Holy See. From the beginning, the Congregation had its seat in Rome, near the famous Piazza de España. Its premises also housed the archives. Until today the Congregation's files constitute a separate group, not included in the central Vatican Archives, although it is officially connected with it; the researchers and searchers who want to use the collections of the Congregation are bound by the same requirements as those worked out for the main Vatican Archives. For several years, the collections documenting the activities of the Congregation have been located in a newly built building on Gianicolo Hill, not far from the Vatican. It is our moral duty to disseminate information about the resources of the Congregation for the Evangelization of Peoples, one of the papal agencies for fulfilling the obligation to proclaim the Good News to the whole world.

Authors: Sterczewska Iwona
Published: January 2024

Mieczysława Biegańska was born on April 2, 1866 in Gołaszewo in the Włocławek poviat. She was the daughter of Eng. Henryk Rezenfeld and Ludwika née Płaska. She started her education in Warsaw and continued in Krakow. In 1880, she moved with her parents to Częstochowa. She worked as a teacher in a female salary, where she taught Polish. In 1885, she married a doctor, Władysław Biegański. The fruit of this marriage were two daughters Halina Płodowska (doctor of philosophy) and Ludomir Wanda Królikowska (doctor of chemistry). Together with her husband, she was involved in social activities, including She belonged to the Knowledge Promotion Society, the Polish Touring Society and the board of the School Care Society in Częstochowa. She was among the organizers of the Industry and Agriculture Exhibition in Częstochowa in 1909, and in the years 1915-1917 she was the only woman to teach at self-education courses in Częstochowa. After her husband's death, she continued his works. She took care of, among other things, the organization of the public library in Częstochowa, to which she donated over 100 publications from her husband's collection. In 1918, she was elected to the board of the Polish National Electoral Organization. She published her husband's biography and wrote a sketch about Cyprian Norwid. She died on June 3, 1954 in Częstochowa.

The use of assistive technology to minimise educational learning barriers for learners with cerebral palsy
Authors: Botha Soené , Mihai Maryke Anneke
Published: January 2024

Cerebral palsy (CP) poses unique challenges in education because of motor impairments and communication difficulties. Assistive technology (AT) offers innovative solutions to address these barriers and create inclusive learning environments. In this article, we examine the use of assistive technology in minimising learning barriers for learners with cerebral palsy. We conducted semi-structured interviews with educators teaching at a CP school and learners who have been diagnosed with CP and observed lessons. The findings illustrated that learners with CP experience many barriers to learning, but with the use of AT by learners and educators, these barriers can be minimised. Recommendations include more training for learners and educators in the use of AT and a more supportive environment. More research is needed on the training programs needed to educate learners and educators on AT and how educators can use AT to bring about transformation in their lessons.
Enhancing pedagogy for teaching visual arts in the South African Foundation Phase classroom: A collaborative endeavor
Authors: de Kock Mari , Marais Elma , Botha Carolina
Published: January 2024

In this article, we report on the pedagogy of a cohort of South African Foundation Phase teachers in the praxis of visual arts. We used participatory action learning and action research (PALAR) as paradigm and methodology and data was generated collaboratively through arts-based strategies such as photovoice, visual journaling, and reflexive group conversations. We analysed the data using an inductive analysis approach. The data indicated a set of extrinsic and intrinsic barriers experienced by the participants in the praxis and pedagogy of visual arts in a South African context. We provide recommendations for Foundation Phase teachers, school management teams, and governmental Departments of Education. This study contributes to the field of arts education by highlighting the plight of generalist teachers having to teach visual arts without sufficient training or support. We create opportunities for arts educators to contribute to the experiences of these teachers.
Trends and insights on multiple intelligences in Islamic schools: A bibliometric analysis
Authors: Kadis Kadis , Imron Ali , Mustiningsih Mustiningsih , Sumarsono Raden Bambang
Published: January 2024

In this comprehensive study, we explore the intersection between Multiple Intelligences (MI) theory and Islamic educational systems, employing bibliometric tools like Descriptive analysis and Author Network Visualization to reveal the intricate contours of academic collaboration and research in this domain. An increasing trend in publications and cross-cultural collaborations, particularly involving the United States, Indonesia, and Turkey, underscores the global relevance of integrating modern psychological theories like MI with Islamic education. Through citation and keyword analysis, we highlight a significant divergence between research on Islamic schools and MI, as well as an emerging interest in applying MI in religious educational contexts. Furthermore, our research identified a seriously alarming gap in the academic literature at this intersection, emphasizing the need for future exploration. In synthesizing the findings, we conclude that the fusion of MI with Islamic pedagogy offers a robust approach to holistic learning in recognizing individual intelligence domains and fostering growth. The integration of these two fields promises to redefine education by melding traditional religious teachings with contemporary insights, creating a pathway for enhanced student understanding, progressive policy formulation, and innovative pedagogical strategies.
An economic analysis of productivity in organ transplantation in Brazil just before and after the COVID-19 pandemic
Authors: Alexandre Marinho
Published: January 2024

We evaluate the productivity of the Brazilian states and the Federal District in transforming potential organ donors into actual donations in the years immediately before and after the COVID-19 pandemic (2019-2022). The Brazilian National Health System (SUS) which is one of the largest public transplant systems in the world, provides full coverage of all costs involved in organ donation, transplants, and post-transplant. We applied Ordinary Least Squares Regression in data from 2019-2022 and the results indicate that there is significant room for improvement in terms of converting potential donors into actual donors. The number of donors with organs transplanted decreased during the pandemic as the productivity of the transplant was affected, although it seems that the structure of the Brazilian transplant system and its technology were not significantly affected permanently.
Application of (bio) chemical engineering concepts and tools to model genetic regulatory circuits, and some essential central carbon metabolism pathways in living cells. Part 4. Applications in the design of some Genetically Modified Micro-Organisms (GMOs)
Authors: Gheorghe Maria
Published: January 2024

In the first part of this work, the general Chemical and Biochemical Engineering (CBE) concepts and rules are briefly reviewed, together with the rules of the control theory of Nonlinear Systems (NSCT), all in the context of (i) deriving deterministic Modular Structured Kinetic Models (MSDKM) to describe the dynamics of metabolic processes in living cells, and (ii) of Hybrid Structured Modular Dynamic Models (HSMDM) (with continuous variables, linking the cell-nano-scale MSDKM state variables to the macro-scale state variables of the bioreactor dynamic model). Thus, in the HSMDM model, both prediction quality and its validity range are improved. By contrast, the current (classical/default) approach in bioengineering practice for solving design, optimization, and control problems based on the math models of industrial biological reactors is to use unstructured Monod (for cell culture reactor) or simple Michaelis-Menten (if only enzymatic reactions are retained) global kinetic models by ignoring detailed representations of metabolic cellular processes. By contrast, as reviewed, and exemplified in the second part of this work, an accurate and realistic math modelling of the dynamic individual GERMs (gene expression regulatory module), or genetic regulatory circuits (GRC), and cell-scale CCM (central carbon metabolism) key-modules can be done by only using the novel holistic ’Whole-Cell Of Variable-Volume’ (WCVV) modelling framework, under isotonic/homeostatic conditions/constraints introduced and promoted by the author. An example was given in the same Part 2 for the case study of a dynamic model for the oscillating glycolysis coupled with the Tryptophan (TRP) oscillating synthesis in the E. coli cells.
