Paradox, cybernetics and infinite poetry
Authors: Doyle Kate
Published: June 2024

How can absence make presence become? The question turns a usual notion of form inside out; it subverts normative habits in drawing distinctions. If we adapt the models of time by which we might consider such things (and not-things), the relational terms of form can shift. Two lines of inquiry are pursued in this article. The first is an investigation of form and its relation to time. The second is an exploration of paradox in describing forms of art. Both are cybernetic in their framework and approach. The ‘Hastig’ (‘Hastily’) movement of Robert Schumann’s 1839 piano work Humoreske is the form that serves as site for the two inquiries to intertwine. Its construction presents a paradox through which form and time may be called into question. In considering Schumann’s composition as a re-conceiving of form and time, an idea emerges; art can make us aware of the constraints and possibilities of our models and our experiences of paradox in living with them.
Papiro de Derveni, col. XIV: Cronos ou Urano?
Authors: Schiappa de Azevedo Maria Teresa
Published: June 2024

A coluna 14 do Papiro de Derveni exemplifica um conjunto de questões interpretativas que este comentário alegórico ao mais antigo poema órfico conhecido levanta. Procuramos analisar aqui: 1) dificuldades de sobreposição linguística em textos de épocas diversas, como mostra o vocabulário (ekthroiskein, aidoion); 2) excessos interpretativos que o comentador não evita, ao trazer para o plano cosmogónico dados e eventos da teogonia subjacente ao poema. Daí resulta uma linguagem ambígua, que acrescenta novos “enigmas” a um poema já de si enigmático. Assim acontece com “o grande feito” (meg’ erexen), tradicionalmente associado a Cronos, que em 14.8 se atribui a Urano, como as regras da gramática comprovam. Interpretação que se complementa pelo entendimento da forma aphairethenai como voz media e não passiva.
Eugénio de Andrade - sob o signo de Kronos
Authors: António Hörster Maria
Published: June 2024

Em foco colocou-se a questão da passagem do tempo e dos seus reflexos na obra de Eugénio de Andrade. Particular interesse mereceu a motívica e sua eventual evolução ou renovação ao longo do tempo. Entre os aspectos considerados encontram-se, enquanto traços das épocas mais tardias, a ecfrasis, a exploração de relações intertextuais ou a actividade de tradução. Entre a multiplicidade dos intertextos convocados na obra do poeta, deu-se algum destaque ao legado grego.
Szeged, az iskolaváros.
Authors: Fizel Natasa
Published: June 2024

Tanulmányom fókuszában az a kérdés áll, hogy Szeged esetében a dualizmus időszakában milyen események vezettek az iskolavárossá váláshoz, valamint, hogy Szeged város lakossága a 20. század elején mennyire volt egységes abban az elképzelésben, hogy a település fejlődésének egyik útja az iskolavárosként való kiteljesedés, azaz az egyetemi várossá válás.
A szociálisprobléma-megoldás, a megküzdési stratégiák és az asszertív kommunikáció egyéves drámaalapú fejlesztése 10-11 évesek körében
Authors: Balogh-Pécsi Anett
Published: June 2024

A tanulmányban egy 10-11 évesekkel (n = 18) végzett kontrollcsoportos (n = 28) fejlesztés eredményeit ismertetjük. A kommunikációfókuszú fejlesztőprogram célja a szociálisprobléma-megoldás, a megküzdési stratégiák és az asszertív kommunikáció fejlesztése volt drámapedagógiai módszerekkel. A program elején és végén három kérdőívet töltöttek ki a diákok (Assertiveness Questionnaire, AQ, Erickson és mtsai, 2016; Balogh-Pécsi és Kasik, 2020; Social Problem-Solving Inventory–Revised, SPSI–R, D’Zurilla és mtsai, 2002; Kasik és mtsai, 2010; Ways of Coping Questionnaire, WCQ, Folkmann és Lazarus, 1988; Rózsa és mtsai, 2008), mindegyik megfelelő megbízhatósági mutatókkal rendelkezett. Az egyéves, 18 alkalomból, kéthetente 90 perces foglalkozásból álló program a kísérleti csoportban három területen eredményezett jelentős változást. A feltételezésünkkel ellentétben a racionalitás mint problémamegoldó stílus nem erősödött, ugyanakkor jelentősen csökkent az impulzív, érzelemközpontú megoldói stílus és az elkerülő-menekülő megküzdési stratégia, valamint nőtt a konfrontálódás mint megküzdési stratégia gyakorisága. Mindhárom terület esetében jelentős magyarázóerővel bír az asszertív kommunikáció. Az eredmények alapján az egyéves csoportos fejlesztés hatékony módja néhány olyan problémamegoldói stílusnak és megküzdési stratégiának, amelyek a hazai vizsgálatok alapján a serdülőkorban számos életvezetési nehézséget okozhatnak, vagy alkalmazásuk kevésbé hatékony megoldáshoz vezet.
(Yet another) way to prove the Pythagoras’ theorem
Authors: Kumar K S Ajay
Published: June 2024

This article attempts a new way of proving the Pythagoras’ theorem. For centuries, people have used diverse tools such as combinatorics, calculus, geometry, algebra and trigonometry to come up with hundreds of different ways to prove the theorem. The contributors who have shown these new ways have been equally varied and diverse - ancient mathematicians, modern academic and recreational mathematicians (including Miss E A Coolidge, a blind girl), philosophers, high-school students, a former chief economist of the World Bank, and even a former president of the United States. Here, I use some geometry, trigonometry and algebra to prove the theorem. The reason why I even tried looking for one more way to prove it is probably best paraphrased by the character Lisa Simpson (from The Simpsons) - I guess the hunt was more fun than the catch.
ADDRESSING THE IMPACT OF FIBROMYALGIA ON FEMALE SEXUAL FUNCTION, ITS CLINICAL AND THERAPEUTIC IMPLICATIONS: AN INTEGRATIVE REVIEW
Authors: Grunbaum Sergio
Published: June 2024

Fibromyalgia (FM) is a very common rheumatic syndrome characterized by chronic musculoskeletal pain, accompanied by complex symptoms including sexual and reproductive disorders, urinary symptoms, depression, sleep disorders, psychological changes and irritable bowel syndrome. Sexual dysfunction (SD) is defined as the inability to participate in sexual activity satisfactorily and the prevalence reaches 40% among women. Fibromyalgia is directly related to sexual dysfunction, and the main factors responsible for the change in sexual function in these women come from pharmacological, physical and psychological changes. This study aims to verify the impact of fibromyalgia on female sexual function, its clinical and therapeutic implications according to scientific studies found in the literature over the last ten years. An integrative literature search was carried out in the LILACS, PubMed and SciELO databases, combining the words and descriptors fibromyalgia and female sexual dysfunction. The articles were selected by reading the title, abstract and full text respectively. At the end of the selection process, 13 articles were included. Studies show that fibromyalgia has a negative impact on female sexual function. Taking into account the general context of fibromyalgia disorders, especially the negative impact they have on female sexual functioning, we can emphasize the extreme importance of physiotherapy in women's health to treat such sexual dysfunctions in women with fibromyalgia, providing them with a better quality of life.

Authors: Sakovych O. O. , Antoniuk Ya. O. , Humeniuk A. F. , Zhebel V. M.
Published: June 2024

The increase in the prevalence of cardiovascular disease has caused a rapid increase in the risk of developing heart failure. For many years, chronic heart failure (CHF) has occupied one of the leading positions in the structure of cardiac and all-cause mortality worldwide, resulting in not only negative social, but also economic effects. To optimize the timely detection of this pathological condition, laboratory biomarker-based diagnostics of heart dysfunction is widely used along with echocardiographic examination. Brain natriuretic peptide (BNP) is currently considered one of the most well-known and informative biochemical markers in heart failure.
The aim of the work was to cover the results of current scientific research according to the principles of evidence-based medicine regarding the use of BNP and its precursor NT-proBNP for the diagnosis of CHF, prognosis and monitoring of the treatment effectiveness. To achieve this goal, an analysis of literary sources published in scientometric databases such as ScienceDirect, Web of Science, Google Scholar, PubMed, Scopus for the period 2013–2024 was carried out.
Conclusions. BNP and NT-proBNP have been found to be informative markers for the early diagnosis of chronic heart failure and can also be recommended for dynamic assessment of patients’ condition and the effectiveness of their treatment. It is proposed to continue the research on clarifying the threshold diagnostic levels of the biomarkers in patients with chronic heart failure and comorbid conditions such as type 2 diabetes mellitus, obesity, as well as in consideration of their sex, age, racial and ethnic characteristics, which in the future would promote the optimization of timely diagnosis, selection of appropriate treatment and improvement of further prognosis.

Authors: Ovcharenko M. O. , Verbytskyi Ye. Yu. , Radchenko T. M. , Kazakov V. Ye. , Chumakova I. O.
Published: June 2024

Aim. To discuss the functional properties of melatonin which plays a key role in the expression of psychopathological disorders following traumatic brain injury (TBI).
The influence of melatonin on neurochemical changes, which may lead to various mental disorders, has been analyzed. Specifically, its impact on asthenia, cognitive impairments, emotional instability, and insomnia, which are among the main symptoms accompanying TBI in the chronic phase, has been examined. The importance of studies on melatonin as a neurotransmitter and its role in the circadian rhythm regulation, which is often impaired as a consequence of TBI, has been emphasized. The mechanisms underlying these disorders may be related to dysfunction of the hypothalamus and interhemispheric interactions. Melatonin may influence the recovery processes after TBI, reducing inflammation and providing optimal conditions for tissue regeneration. It opens up new possibilities for the development of therapy aimed at reducing the impact of trauma consequences on patients. Earlier studies have also indicated the option of using melatonin as an antioxidant, which can protect brain tissue from further damage caused by recovery processes after injury.
Studies on pharmacological modulation of the melatonin system could be useful for developing new methods for treatment and prevention of mental disorders associated with TBI. Examining the action of melatonin receptor antagonists and agonists can help to choose optimal treatment strategies aimed at correcting disorders arising as a result of trauma. It holds promise for faster and more complete recovery of mental health in TBI patients.
Conclusions. Considering the significance of melatonin in regulation of physiological processes, further studies may enrich understanding of its role, ensuring the development of more effective treatment methods. Given the safe profile of melatonin and its availability as a supplement, supportive studies in this direction have the potential to positively impact clinical practice.

Authors: Kobza I.I. , Nesterenko I. R.
Published: June 2024

The aim was to assess the long-term outcomes of the left renal vein reimplantation in case of nutcracker syndrome.
Materials and methods. The study included 56 patients with critical stenosis of the left renal vein who underwent left renal vein reimplantation from May 1999 to August 2023. 10 patients were operated on between 1999 and 2013, that provided an opportunity to study long-term outcomes in the period from 7 to 21 years (a retrospective part). 46 patients underwent the surgery between 2018 and 2023 (a prospective part).
Results. According to the long-term outcome analysis of the left renal vein reimplantation conducted in the period from 3 months to 21 years, all the patients reported a gradual regression of clinical symptoms, namely, resolution of pain syndrome, hematuria, proteinuria, erectile dysfunction, dyspeptic phenomena. Ultrasonography detected a statistically significant increase in the left renal vein diameter from 1.90 ± 0.87 mm to 7.50 ± 0.76 mm (p = 0.0123) in the aorto-mesenteric segment after the surgery and a statistically significant decrease in the peak systolic velocity from 187.30 ± 2.95 cm/sec to 38.70 ± 0.76 cm/sec (p = 0.0178) in this area. A statistically significant decrease in the left gonadal vein diameter from 6.60 ± 1.30 to 4.20 ± 0.84 mm (p = 0.0118) after the surgery was noted and a decrease in the left kidney parenchymal thickness from 2.20 ± 0.46 to 1.60 ± 0.54 mm (p = 0.0123) was observed.
Conclusions. Reimplantation of the left renal vein has been proven to be an effective treatment for critical stenosis of the left renal vein.

Authors: Ishchenko M. S. , Rudenko K. V. , Lazoryshynets V. V. , Vitkovskyi Yu. I. , Tregubova M. O. , Danchenko P. A.
Published: June 2024

Hypertrophic cardiomyopathy (HCM) is a prevalent genetic heart disease with a worldwide prevalence. Its estimated incidence in young individuals is approximately 1 case per 500 population. HCM in adults can be clinically diagnosed through visualization, either via 2D echocardiography or cardiac magnetic resonance (CMR) imaging, where the maximum thickness of any left ventricular (LV) segment, measured in end-diastolic phase, is 15 mm in the absence of other hypertrophy causes.
Aim. To demonstrate the role and diagnostic capabilities of CMR as a powerful diagnostic tool for detecting and evaluating sudden cardiac death (SCD) risk factors in patients with HCM.
Materials and methods. From January 2022 to September 2023, 236 CMR examinations were conducted and analyzed at the Diagnostic Radiology Department of Amosov National Institute of Cardiovascular Surgery in patients with suspected HCM. All examinations were performed on a magnetic resonance tomograph “Toshiba Vantage Titan 1.5T” until May 2023, and “Canon Vantage Orian 1.5T” from May to September 2023, with ECG and respiratory synchronization as well as intravenous injection of gadolinium-based contrast agent (Gadovist 1.0) at a dose of 0.1 mL/kg body weight. Statistical and mathematical data processing was performed by using the Statistica 6.0 (StatSoft Inc., USA) application package.
Results. The mean age of the examined patients was 41 ± 28 years, there were 142 male (60 %) and 94 (40 %) female patients. Symmetric non-obstructive HCM was identified in 39 patients (16.5 %) and 184 patients (78.0 %) had asymmetric obstructive HCM. Apical HCM was diagnosed in 4 patients (1.5 %), and midventricular HCM – in 9 patients (4.0 %) including one patient with a combination of midventricular and apical forms.
Risk factors for SCD were identified in 60 patients (25.4 %) with myocardial thickness exceeding 30 mm, 8 patients (3.3 %) with apical aneurysm, 4 patients (1.6 %) with reduced LV systolic function (LV ejection fraction <50 %), and 164 patients (69.4 %) with pathological late gadolinium enhancement.
Conclusions. CMR is a modern, high-precision and powerful diagnostic method that plays a key role in identifying and assessing SCD risk factors in patients with HCM. CMR helps to identify HCM patients at high SCD risk who may benefit from preventive measures such as implantable cardioverter-defibrillator therapy.

Authors: Bowers Patrick , Graydon Kelley , Ryan Tracii , Lau Jey Han , Tomlin Dani
Published: June 2024

This study presents a scoping review of research on artificial intelligence (AI)- driven virtual patients (VPs) for communication skills training of healthcare students. We aimed to establish what is known about these emergent learning tools, to characterise their design and implementation into training programmes. The preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews framework was consulted. Searches occurred in six online databases to capture relevant articles from 2014 to 2024. Eight articles from five disciplines met inclusion criteria. A variety of design approaches, creation tools and VP appearances exist. Educational considerations such as consultation of educational theory, curricular integration and provision of feedback was overall lacking. Neutral to positive evaluations of satisfaction and acceptance of the VPs were provided by most students. Emerging literature suggests AI-driven VPs are increasingly being utilised for communication skills training, although their effectiveness is not established. Careful consideration of technological design features, educational theory and evidence regarding communication skill development should occur by clinical educators wishing to include AI-driven VPs in their training programmes. Further empirical research involving key stakeholders is needed to learn more about this technology.
 
Implications for practice or policy:

Students may find benefit from having opportunities to use AI-driven VPs for communication skill development.
Developers could avoid some criticisms of AI-driven VPs by carefully addressing technical issues
Educators should consult evidence on educational and communication theories when utilising AI-driven VPs.
Researchers should consider increasing the involvement of key stakeholders in the design and evaluation of communication skill focused AI-driven VPs.
Zasoby użytków rolnych w Polsce w latach 2010–2020
Authors: Głębocki Benicjusz , Kacprzak Ewa , Koliński Krystian
Published: June 2024

W artykule przedstawiono zmiany zachodzące w zasobach użytków rolnych w Polsce w latach 2010–2020. Szczególną uwagę zwrócono na identyfikację zmian w rozmieszczeniu użytków rolnych. Analizę przeprowadzono na 3 poziomach – krajowym, wojewódzkim i gminnym, a jej podstawą były dane Głównego Urzędu Geodezji i Kartografii w Warszawie (GUGiK). Stwierdzono, że postępuje proces kurczenia się zasobów użytków rolnych (ubyło 498,3 tys. ha), a jego dynamika zwiększyła się w porównaniu z pierwszym dziesięcioleciem XXI w. (2000–2010 ubytek 369,4 tys. ha). To przede wszystkim konsekwencja rozwoju społeczno-gospodarczego kraju. Użytki rolne traktowane są głównie jako swoisty rezerwuar gruntów pod inwestycje i z tego względu zapewne nadal zmniejszać się będą ich zasoby. Mając na uwadze bezpieczeństwo żywnościowe, a także szeroką paletę funkcji, jakie pełnią użytki rolne w środowisku przyrodniczym, niezbędne jest odpowiedzialne gospodarowanie użytkami rolnymi i prowadzenie monitoringu ich zasobów oraz zmian zachodzących w strukturze użytkowania ziemi.
Complex Temporalities, Poetic Niches, and Insular Moments: The Poetry of Sepp Mall
Authors: Siller Barbara
Published: June 2024

The South-Tyrolean author Sepp Mall, born in 1955, is renowned for his intricate artistic poems. For the writer, composing poetry is a practice of deceleration: an act of both reducing speed and slowing down. Similarly, he describes the process of reading poems as a practice of standing still, of reflecting, and as a highly attentive practice of perceiving and sensing (Mall, 2022). The following article brings Mall’s long poem “Unwirkliches Blau (Rondo)” (Unreal blue [Rondo]) from his most recent poetry collection Holz und Haut (Wood and skin) into focus, and discusses in which ways the poem opens up novel spaces of perception regarding time by seizing alternate temporalities – in other words, non-human-centred temporalities, as suggested by the poem itself. These spaces of perception manifest as utopian niches in the sense of deep, small, and secluded chronotopes of imagination and perception, which brim with transformative potential as they offer a means of widening one’s perception of temporalities.

Published: June 2024

Atherosclerosis (AS) is a chronic inflammatory disease that leads to the formation of atherosclerotic plaques in arterial walls, which can eventually result in cardiovascular diseases. It has been confirmed that the imbalance in the polarization of M1-type pro-inflammatory and M2-type anti-inflammatory macrophages in AS plaques is closely related to plaque instability and the development of cardiovascular diseases like AS-related heart and cerebrovascular diseases. Triptolide (TP) is a promising drug for the treatment of AS due to its anti-inflammatory and anti-proliferative effects. However, its poor solubility and lack of specificity limit its clinical application. We developed a targeted delivery system for TP to M1-type macrophages using mesoporous polydopamine (MPDA) nanospheres modified with the LyP-1 peptide. We then observed the performance of this targeted delivery system and explored its regulatory effects on macrophage polarization in AS. The results showed that the LYP-1-modified MPDA-TP delivery system had an average encapsulation rate of 66.5%, a drug loading capacity of 4.5%, and an average diameter of 250 nm. It exhibited excellent targeting ability and drug release rate towards target cells. LYP-MPDA-TP was capable of inhibiting the proportion of M1 macrophages induced by oxidized low-density lipoprotein stimulation in mouse macrophages, promoting apoptosis in M1-type macrophages significantly, and demonstrating a significant inhibitory effect on AS in experimental animals. The LYP-1 peptide-modified MPDA delivery system provides a new approach for TP treatment of AS and an important theoretical basis and methodological reference for the design of targeted delivery systems for anti-AS nanoparticles.
Enhanced Image-Based Malware Multiclass Classification Method with the Ensemble Model and SVM
Authors: Haile Melaku Bitew , Walle Yelkal Mulualem , Belay Abebech Jenber
Published: June 2024

Malware has become one of the biggest risks to security due to its rapid expansion. Therefore, it must be quickly detected and removed. While convolutional neural network (CNN) models have expanded to include ensemble and transfer learning approach from previous individual CNN architectures, relatively few studies have compared how well these approaches perform when it comes to malware family detection. A small number of malware varieties have been the focus of several research efforts’ studies. In this study, both of these issues were resolved. We present our own ensemble model for the classification of malware diseases into 34 types. We merge the Microsoft malware dataset with the Malimg dataset to increase the number of malware families identified by the model. To reduce training time and resource consumption, the suggested model utilized the most significant malware features, which are chosen based on the Least Absolute Shrinkage and Selection Operator method, for the purpose of classifying the malware classes. The experimental findings demonstrate that the ensemble model’s accuracy is 99.78%. Based on the experimental results, we conclude that the model will help with real-world malware classification tasks.
Hydroxyapatite biomaterials: a comprehensive review of their properties, structures, clinical applications, and producing techniques
Authors: Ahmed Lana O. , Omer Rebaz A.
Published: June 2024

Before employing a biomedical material in medical applications, a researcher must possess comprehensive knowledge regarding its chemical, physical, biological, structural, and mechanical properties. Hydroxyapatite (HAp, Ca10(PO4)6(OH)2) is a vital constituent of the calcium orthophosphate group. The material exhibits good dielectric and biological compatibility, diamagnetic behavior, thermal stability, osteoconductivity, and bioactivity. Additionally, it has a Ca:P molar ratio of 1.67. Because HAp has a chemical composition that is quite similar to normal bone and teeth, it has the potential to be used as a material for implant implantation in fractured portions of the human skeletal system. Many ways for generating HAp nanoparticles have been found as a result of the increasing usage of HAp in medicine. The conditions under which HAp is generated determine its physical and chemical properties, crystalline structure, and form. This study provides detailed information on the HAp’s characteristics and manufacturing procedures, as well as revealing the structure and its properties.
Friendshoring in global production networks: state-orchestrated coupling amid geopolitical uncertainty
Authors: Kalvelage Linus , Tups Gideon
Published: June 2024

In an era of multiple crises and geopolitical uncertainty, the need to deal with heightened risk drives states to locate strategic global production networks (GPNs) in geopolitically aligned states, a trend known as friendshoring. In this paper, we contribute to the literature on the role of geopolitics in GPNs by exploring why and how states engage in friendshoring. To this end, we distill from the literature three geopolitical imperatives that, in addition to more conventional GPN imperatives, drive strategic coupling dynamics: reducing risk exposure, (de-)weaponizing supply chains, and maintaining extraterritorial influence. States and state-linked institutions respond to these imperatives by actively “pushing out” new inter- and extra-firm relations in GPNs which often includes previously neglected regions in the global periphery – even when regional assets require substantial transformation. To achieve this, states orchestrate efforts at extraterritorial de-risking, outward-oriented network brokering, and extraterritorial institution-building to actively alter the coupling conditions. By applying our framework to qualitative research on the Chinese soybean GPN in Tanzania and German-led green hydrogen investments in Namibia, we demonstrate how GPN friendshoring relies on both coercion or incentivization orchestrated by the state.
Are Corporations Responding to Civil Society Pressure?
Authors: Rieger Annika
Published: June 2024

Previous research in the world-society tradition associates improvements in nation-level environmental outcomes with greater civil society integration. However, research in the world-systems tradition indicates these improvements depend on a nation’s position in the global political-economic hierarchy. To test whether these patterns are present at the organizational level, I estimate a multilevel model using corporate emissions data from the Carbon Disclosure Project and include interactions between world-system position and three measures of civil society integration: number of NGOs, proportion of corporations with climate-management incentives, and number of corporate UN Global Compact signatories. I find that the relationship between civil society pressure and corporate emissions varies with a nation’s position in the world-system. The NGO measure is associated with greater emissions in non-core nations, possibly due to means–ends decoupling or corporate greenwashing. The climate-incentives measure is associated with less corporate-level emissions in the core and more emissions in non-core nations, possibly due to successful regulation in the core leading to ecologically unequal exchange. I argue that reducing corporate emissions requires accounting for increasingly complicated macro-sociological contexts, as corporations are pressured by and incorporated into world society and participate in patterns of unequal exchange in the world-system.

The creation and optimisation of memristor models with different topologies and physical mechanisms have received increasing attention in recent years. Memristors, known for their unique resistive switching mechanism, have garnered significant interest as promising components for next-generation computing. However, to effectively design and test memristor-based circuits, it is crucial to have a mathematical representation of the experimentally determined current-voltage characteristics of memristors. This paper proposes a model and conducts an analysis that offers insights into memristor technology, beginning with its characteristics and extending to simulations involving various parameters. The proposed model and its dependency on temperature are implemented using MATLAB. The model captures changes in current characteristics concerning the fundamental voltage without using any window functions. Thus, it accurately represents the variation in memristance with temperature, contributing to a more precise and observed modelling approach.
Niveles de razonamiento proporcional y micromundos. Un estudio en telesecundaria unitaria
Authors: Lugo Lugo Carlos Alberto , García-Torres Erika , Palmas Pérez Santiago Alonso
Published: June 2024

[Objective] Proportional reasoning is a type of complex thinking that involves recognizing comparisons such as the covariation between magnitudes and multiple comparisons. The aim of this study was to analyze proportional reasoning of students from unitary tele-secondary education using the levels proposed by Karplus (1983) through a microworld like GeoGebra. In the microworld, students can explore and construct meanings about mathematical objects. [Methodology] Four activities were designed in GeoGebra, which were administered to 18 students from a unitary tele-secondary school, an educational modality in Mexico. [Results] It was found that participants are at initial levels that correspond to additive, qualitative, or erroneous structures to justify their procedures. The more complex levels of proportional reasoning, related to the use of ratios and constants of proportionality, were achieved when students interacted with each other and with the microworld. The reasoning levels are not mutually exclusive, as students can reason differently depending on the situation and the software's capabilities. [Conclusions] The use of microworlds in exploring proportional reasoning enables actions that cannot be carried out with pencil and paper, providing opportunities to interact with moving constructions.

Для изучения особенностей магматизма коллизионных зон наиболее информативным является позднеколлизионный тектоно-магматический этап, с которым связан наибольший объем и разнообразие образующихся магматических ассоциаций. В данной работе гранитоидный и базитовый позднеколлизионный магматизм рассматривается на примере раннекаледонских магматических комплексов Западного Сангилена (Тувино-Монгольский массив). Приводятся результаты геохронологических, петрографических, петрогеохимических и минералогических исследований пород комбинированной дайки Сайзырал и салических даек. На рубеже ~ 485 млн лет, наряду с формированием массивов высококалиевых гранитоидов, происходит внедрение и становление комплекса гранитоидных и минглинг даек. Минглинг дайка Сайзырал сформировалась при совместном внедрении и смешении основных и кислых магм в зону пониженного давления в пределах Эрзинской тектонической зоны на среднекоровом уровне глубинности. Взаимодействие контрастных магм протекало в два этапа. На первом этапе в процессе транспорта контрастной смеси происходило интенсивное механическое смешение и привнос в базиты LIL, HFS элементов, Th и U из гранитоидов, что привело к изменению геохимических характеристик базитов. На втором этапе совместная кристаллизация магм сопровождалось гравитационным осаждением более плотных основных магм и образованием на контакте контрастных пород узких зон переходного состава.

The best source of information about the specific features of magmatism in collision zones is the late collisional tectono-magmatic stage, which is associated with the largest volume and diversity of the resulting magmatic associations. In this paper, granitoid and mafic late collisional magmatism is considered using the example of Early Caledonian igneous complexes of Western Sangilen (Tuva–Mongolian massif). Results of geochronological, petrographic, petrogeochemical, and mineralogical studies of the rocks of the Saizyral mingling dike and salic dikes are presented. Approximately ~485 Ma, high-potassium granitoid massifs formed simultaneously with the intrusion and occurrence of a complex of granitoid and mingling dikes. The Saizyral mingling dike resulted from the joint intrusion and mixing of basic and silicic magmas in a low-pressure region within the Erzin shear zone at a middle crust depth level. Interaction of contrasting magmas is comprised of two stages. The first stage occurs during the transport of a contrast mixture and comes down to intensive mechanical mixing and the introduction of LIL and HFS elements, as well as Th and U from granitoids into the mafic rocks. This changes the geochemical characteristics of the mafic rocks. The second stage is when the joint crystallization of magmas is accompanied by gravitational sedimentation of denser mafic magmas and the formation of narrow zones of intermediate composition at the contact of contrasting rocks.

Reverse design and additive manufacturing technologies are fast ways to develop customised products. In this study, furniture protective foot covers were taken as the design object. Using flexible filaments of polylactic acid (PLA) and the development process of reverse design to additive manufacturing, the protective foot covers were designed and manufactured to fit the shape of the chair feet. Furniture protective foot covers have high practical value. They have a certain buffering effect, avoiding the damage caused by the collision of furniture feet with the ground when moving furniture; secondly, they reduce the noise generated by the collision of furniture feet with the ground, creating a quiet and comfortable home environment. According to the finite element simulation results, the maximum stress value of the European-style chair installed with protective foot covers was decreased by 90.8% in the case of vertical fall, which verifies that the protective foot covers have an obvious buffering effect. Noise test results show that the noise of the European-style chair installed with protective foot covers was decreased by 51.0%, which verifies that the protective foot covers have an obvious quieting effect.

The Sika Deer is a valuable and traditional animal that has been used for its medicinal properties for over 2,000 years in China, making its first appearance in the Shennong's Classic of the Materia Medica during the Han Dynasty. Modern research has shown that the main by-products of Sika Deer are rich in a variety of active ingredients, including free amino acids, peptides, chondroitin sulphate, prostaglandins, phospholipids, hormones, biogenic amines, inorganic elements, etc. The effects of Sika Deer are extremely wide-ranging. Its efficacy is also extremely wide, such as the prevention and treatment of cardiovascular disease, physical fitness, delay aging, enhance immunity. From human consumption of venison and blood treatment of disease, has been a history of thousands of years, deer products have been basically formed. Deer products have basically formed a system and scale that can be used for food or medicine. Deer products refer to the products and products of various deer species of the deer family, with antlers, blood, whips, tires, bones and meat as raw materials are widely used in food, medicine, health food and other industries. In recent years, there have been many researches on the chemical composition analysis, pharmacological effects and clinical effects of the main by-products of deer, and the main by-products of deer have shown good medicinal value and have a broad market prospect. The biological effects of antler, fetus, heart, blood and whip were reviewed to summarize their biological effects and to improve the social, economic and biological values of Sika deer. And biological value of the plum blossom deer, so as to provide theoretical references for subsequent research.
