Исследовано влияние двух факторов на контур линии поглощения молекулы водяного пара в смеси с гелием, аргоном, криптоном и ксеноном: зависимости коэффициентов уширения g и сдвига центра линии d от скорости va поглощающей молекулы Н2О (эффект ветра) и изменения скорости Н2О при столкновении с указанными атомами. Для исследования выбраны три линии поглощения молекулы Н2О из полосы n1 + n2 + n3 с различными вращательными квантовыми числами начального квантового состояния. Показано, что наиболее сильно эффект ветра проявляется при взаимодействии молекулы Н2О с атомами аргона, криптона и ксенона. Результаты работы могут быть использованы при анализе спектров поглощения водяного пара в смеси с одноатомными газами.

The influence of two factors on the contour of an absorption line of water vapor molecule in a mixture with helium, argon, krypton, and xenon is studied: the dependence of the broadening coefficients g and shifting coefficient d on the velocity va of the absorbing H2O molecule (wind effect) and the change in the velocity of H2O upon collision with these atoms. Three absorption lines of H2O molecule from n1 + n2 + n3 band with different rotational quantum numbers of the initial quantum state were chosen for the study.

Authors: Batieieva Nataliya , Kyzim Petro , Hryshko Artem
Published: June 2024

Background and Study: The modern type of competitive activity of qualified athletes of acrobatic rock and roll is undergoing contradictory changes in the content of the competitive program “Acrobatics” of the category “Main class contact style” due to an increase in the static performance of acrobatic elements, their number in combinations, where a loss of dynamics in the implementation of the competitive program is observed, which contradicts the definition of “rock and roll” as a dance where the acrobatic elements performed are the emotional, culminating accents of the dance figures. The main purpose of the study is to identify the patterns of the evolutionary process of the content of competitive programs of qualified acrobatic rock and roll athletes.
Material and methods. As a result of the study, a comparative analysis of video materials of the final part of the competition was carried out: the final of the Ukrainian Championship in the category “Basic class contact style” (2010) 6 pairs (n=12); final of the Ukrainian Championship in the category “Basic Contact Style Class” (2023) – 6 pairs (n=12); final of the World Championship category “Basic freestyle class” (2011) –7 pairs (n=14); final of the World Championship category “Basic freestyle class” (2020) – 7 pairs (n=14).
Results. During the analysis of viewing video materials of the final part of the Ukrainian and World Championships, structural changes were identified that affected the percentage of components of the competitive program “Acrobatics” in the category “Basic class contact style”, where acrobatic elements and their combinations with a large number of their components become a priority in the competitive program in relation to the structure of the competitive program “Acrobatics” of the category “Main class free style”.
Conclusions. The evolutionary process of the content of the competitive program in acrobatic rock and roll has been identified, which is carried out due to changes in the Competition Rules, the implementation of new achievements of choreographic different styles of dance figures and the search for extreme, optimally adjusted motor actions in performing complex (high-risk) actions, which in the future involves changes and differentiation of the components of the educational and training process of qualified acrobatic rock and roll athletes.

Introduction: Physical education has many skills to learn, one of which is the long jump skill. The long jump is a branch of athletics learning which is generally less attractive to students, facts on the ground explain that students are not happy with athletics lessons, and students are not serious about taking part in lessons.

Aim: This study aims to develop play activities in physical education learning long jump hanging style based on the CGFU-PM515 concept for elementary school students. The implementation of this activity is made in a circuit so that it can be played individually or in groups in an interesting and fun way.

Method: This development research applies the 4D development model by Thiagarajan with the following steps: (1) Define, (2) Design, (3) Develop, and (4) Disseminate. The developed play activities consist of four types of activities based on their benefits in learning the long jump long jump style, in addition to making it easier to recognize the playing activities being developed, the researcher innovates by giving the name of the letter in each type of activity as follows: "A" for the type of prefix activity , "R" for the type of repulsion activity, "G" for the type of hovering activity, and "O" for the type of landing activity. So that this playing activity can also be called the name "ARGO" playing activity.

Result: The data obtained from this research is in the form of quantitative data, from the data then tested the validity and practicality tests. Test the validity of the products developed by looking at the suitability of several aspects including: (1) Compatibility with basic competencies gets a high validity level with a score of 0.97, (2) The accuracy of the material gets a high validity level with a score of 0.9, (3) Encouraging curiosity has a moderate level of validity with a score of 0.77. Then for the practicality test the results were 96% and based on the criteria for giving a practicality value the results were stated to be very practical.

Conclusion: So it can be concluded that the play activities developed are very interesting, in accordance with learning objectives, and effective for elementary school students.

Published: June 2024

Discrepancies between ICRP phantoms and real patients lead to disparities on patient-dose estimations. This paper aims to compare distribution of dose in organs of male/female individualized-phantoms and ICRP reference phantoms. The absorbed dose estimation was performed using the EGSnrc Monte Carlo code and a parallel source algorithm. In this work were used an individualized-phantom for a man (1.73m/70.3kg) and another for a woman (1.63m/60.3kg) and the male and female ICRP reference phantoms. The comparison of the absorbed dose from each phantom gender was performed using the relative error. The results were expressed in terms of conversion coefficients to brain, lungs, liver and kidneys. The greatest absolute relative error between the organs of the patient-specific and the reference phantom was 22.92% in the liver and 62.84% in the kidneys, respectively for man and woman. There are errors that cannot be disregarded. This paper shows the need for a specific study for each patient or for the population of each country, since there are different body types, which affects the distribution of the organ doses.

Published: June 2024

123I is a radionuclide used for diagnosis in nuclear medicine. Its production in Radiopharmacy Centers poses a risk of external and internal exposure to the workers involved in this practice. Controlling this type of exposure through individual monitoring is necessary to estimate the magnitude of occupational doses. The In Vivo Monitoring Laboratory (LABMIV-IRD) develops techniques aimed at meeting the demand for in vivo monitoring of workers. This paper describes the calibration of a HPGe detection system for monitoring 123I in thyroid geometry in occupationally exposed individuals (OEI). In order to obtain the calibration curve in Efficiency (cps/dps) vs Energy (keV), it is used a thyroid-neck phantom containing a certified activity of 166mHo homogeneously distributed. Based on the calibration curve it is calculated the specific calibration factor for the quantification of 123I in the thyroid. The sensitivity of the technique is evaluated by determining the minimum detectable activity (MDA), minimum detectable intake (MDI) and minimum detectable effective dose (MDED). It was obtained a calibration factor of (0.0079 ± 0.0001) cps/dps, a MDA of 5Bq, a MDI of 2.78x106 Bq and a MDED of 3.23x10-1 mSv. The technique is sufficiently sensitive for in vivo measurement of 123I in the thyroid and is suitable for the monitoring of workers occupationally exposed to this radionuclide in  radiopharmaceutical production plants.

Background and Aims: Early gastric cancers (EGCs) after Helicobacter pylori (H. pylori) eradication often appear as reddish depressed lesions (RDLs); the same features are also appeared in benign stomachs after eradication. We compared clinic-pathological and endoscopic features of benign and neoplastic RDLs after H. pylori eradication.
Methods: 228 neoplastic RDLs after H. pylori eradication were studied. All lesions were divided into neoplastic RDLs (differentiated carcinoma or adenoma, n=114) and benign RDLs (n=114) according to the histology. Clinical and pathological characteristics were compared in neoplastic and benign groups. Endoscopic diagnostic yields using the white light (WL) endoscopy, chromoendoscopy (CE) using indigo carmine dye and the magnifying endoscopy with narrow-band imaging (ME-NBI) were also evaluated in relation to the pathological diagnosis.
Results: Size of neoplastic RDLs was larger than that of benign RDLs (p<0.01). Sensitivity, specificity and accuracy for predicting pathological types of RDLs was 70.1%, 52.6% and 61.4% for the WL, 65.8%, 63.1% and 65.4% for the CE, while the ME-NBI scored better with the 88.6%, 88.6%, 99.1% and 93.9% of sensitivity, specificity and accuracy. The accuracy of the ME-NBI was 99.9% (113/114) in the benign RDLs and 89.4% (101/114) for the neoplastic RDLs. Undiagnosed neoplastic RDLs using the ME-NBI were associated with more differentiated tumors such as adenoma and well-differentiated adenocarcinoma (tub1) and the presence of an unclear demarcation line.
Conclusions: ME-NBI is useful to diagnose RDLs after H. pylori eradiation, while some of neoplastic lesions are difficult to diagnose using the ME-NBI.

County lines: The exploitation of vulnerable members of society
Authors: O’Hagan Andrew , Edmundson Charles James
Published: June 2024

The transport of class A drugs from a urban centre to a coastal or rural location, where a profitable drug market has been identified, is known as county lines. A network of dedicated mobile phone lines are used to coordinate these operations. Through these processes, criminal groups are able to transition into nationwide organisations, moving drugs across one or more police boundary in order to maximise profit. These groups exploit vulnerable people, including children, to move drugs into identified areas, often taking control of their houses. This is achieved using intimidation, coercion and extreme violence. Activities of county lines groups have a highly detrimental effect on vulnerable people and the local communities in which they operate. Criminally exploited individuals are at high risk of drug addiction, sexual abuse and criminal conviction. The recent upsurge in UK crime coincides with the rise in numbers of county line groups since their emergence in 2015. The way that these groups do not hesitate to use extreme violence to intimidate individuals has led to an increase in knife crime and a high number of drug related homicides over the past year. It is vital that vulnerable individuals are safeguarded and that time is taken to identify those at risk. Intervention at an early stage can prevent gang recruitment, exploitation and serious injury or trauma.

Published: June 2024

Introduction: Currently, there is a large part of the adult population affected by a stroke or cerebrovascular accident, and it is the second cause of death and the first cause of acquired disability.1 The high incidence of stroke pathology and the dependency caused by hemiplegia make gait retraining necessary as the main objective in order to recover the patient's autonomy in terms of functionality in activities of daily living and social inclusion.2 Material and Methods: In this study we present the case of a 46-year-old male patient diagnosed with hypertensive hemorrhagic stroke in the left basal ganglia with right hemiparesis. The objective of this study is to objectively analyze gait using portable devices and indicate the appropriate rehabilitation treatment in patients with acquired brain damage. We objectively analyze gait using portable devices and indicate the appropriate rehabilitation treatment in the patient affected by acquired brain damage. As portable devices we use the Bgait mobile application and superficial electromyography to measure neuromuscular involvement. Results: Functionally, the patient presents a significant increase in the capacity of the walking without the need for support products, reaching a community speed without Limitations after opportune treatment based on assessment using portable devices. Conclusion: We think that carrying out the study of gait using portable devices with the incorporation of new technology such as mobile applications, easy to apply in clinical practice, demonstrates the objective values allowing for a precise evaluation.

Published: June 2024

The objectives of this study were to evaluate changes in the lung parenchyma in systemic sclerosis (SS) using ultrasonography; associate this findings with the clinical criteria and high-resolution computed tomography (HRCT). Methods: Thirty SS outpatients of two public hospitals in Brazil and ten healthy subjects underwent pulmonary ultrasound (US) examination, evaluating pulmonary parenchyma alterations in 14 intercostal spaces. The B-lines, structures indicative of pleural septal thickening, when present, were graded by a simplified score. HRCT of lung carried out previously were correlated with lung ultrasound. Results: Changes in pulmonary parenchyma seen by the US in such population were the B-lines, present in 96.67% of the patients. The classification of pulmonary US in this group was normal in 16.67%, mild in 30%, moderate in 36.67% and marked in 16.67% of the cases. Pulmonary US sensitivity in this study was 93% and specificity 77%. Patients with SS in the diffuse form had a higher number of B-lines than those in limited form. Correlation between pulmonary US and the number of B-lines was positive r=0.95; (p<0.001). HRCT scans with reports of pulmonary fibrosis presented more B-lines, r=0.54; (p=0.006). In the correlation between the semiquantitative US lung score and the ACR / EULAR Classification Criteria 2013, there was significant agreement (p = 0.010). Conclusion: The pulmonary parenchyma changes in SS identified through the US in this work were the B-lines. Pulmonary US with semiquantitative B-line score presented high sensitivity for interstitial lung disease (ILD) investigation. The manifestation of diffuse pulmonary parenchymal disease seen by the pulmonary US of this population was compatible with the results of previous studies.

Published: June 2024

Currently, in agricultural production, to ensure that it is not a source of greenhouse gases, without affecting the healthy growth of Phaseolus vulgaris, it is necessary to apply NH4NO3 at 70% since previous studies indicate that values ​​of 100 to 80% are uptake by the plant (data not showed) and generate N2O in addition to contaminating surface and underground water. An alternative solution is to apply NH4NO3 70% and inoculate the seeds with microbial consortia that optimize this nitrogen fertilizer. The objective of this research was to analyze the response of P. vulgaris to Pichia norvegensis, Saccharomyces cervesiae and Xanthobacter autotrophicus NH4NO3 at 70%. The experiment was carried out with a randomized block design; the response variables: germination percentage, days of emergence, phenology: plant height (PH), root length (RL) and biomass: aerial/radical fresh weight (AFW/RFW) aerial and radical dry weight (ADW/RDW) of P. vulgaris. All the experimental data were analyzed by ANOVA/Tukey HSD (P<0.05). The results showed a positive effect of P. norvegensis and X. autotrophicus with 94% germination of P. vulgaris seeds; at seedling stage registered 37.48 cm of PH, 18 cm of RL, 1.96 g of FAW, 1.55 g of RFW, 0.24 g ADW and 0.14 g RDW, all this numerical values ​​statistically were different, compared to 70.7% germination, 28.8 cm PH, 10.66 RL, 0.82 g AFW, 0.29 g RFW, 0.12 g ADW and 0.03 g RDW in P. vulgaris not inoculated with P. norvegensis or X. autotrophicus fed with 100% NH4NO3 , used as relative control (RC). These results support that it is feasible to use interactions between yeasts and endophytic bacteria, such as P. norvegensis and X. autotrophicus to activate and improve the physiological capacity of P. vulgaris root to increase NH4NO3 70% uptake, which prevents the release of greenhouse gases associated with global warming, loss of fertility and contamination of surface and groundwater.
Clarification of the genesis of deposits of Qala Suite of the Hovsan-Zykh area by methods of stratigraphic and lithofacies analysis based on 3D seismic and Well Logging data (Absheron oil and gas bearing region, Azerbaijan)

Published: June 2024

The major share of oil, gas and gas condensate produced in Azerbaijan comes from deposits of the Lower Pliocene Productive Series. In this relation, a detailed study of the struc- ture of the Productive Series (PS) deposits and the conditions of their formation is of great practical importance. For this purpose, new, highly data-rich methods of analysis have been widely used in recent years: seismic and sequence stratigraphy. The prediction of non-anticlinal traps and reservoirs in conditions of sharp facies variability of deposits is an urgent problem facing these methods. In recent years, various methods of facies analysis have also been widely used, which allows us to reconstruct the facies conditions and sedimentation conditions of sand bodies and clay de- posits of the PS in the absence or limitation of core material. In this connection, the focus of the work was on studying the conditions of formation of sandy reservoir bodies and clayey screen rocks of fluvial-deltaic and coastal-marine genesis within the Productive Series of the Qala Suite, which is promising from the point of view of oil-bearing capacity, according to both seismic survey and well logging data. The object of the study was the Hovsan-Zykh area, located 20 km east of Baku, in the southern coastal part of the Absheron Peninsula. The industrially significant oil bearing capacity in this area is associated with the deposits of the Qala Suite Productive Series. In order to study the formation conditions of the Qala Suite deposits based on seismic data, paleostructural constructions, as well as seismic stratigraphic and seismic facies analysis of 3D seismic data were performed. Seismic stratigraphic complexes were identified in the section of the study area, and various facies types were defined and analyzed within the Qala Suite strata. Sequence-stratigraphic analysis was performed on the basis of well logging data within the studied formation. In the process of research, the method of logging facies was also applied, which allows lithologic and facies diagnostics of sediments based on well logging data. Taking into consid- eration the new seismic and reinterpreted well data, the deposits in the eastern and western parts of the Hovsan field are divided into individual objects. In the area under study, the deposits of the Qala Suite are represented by alternating interbeds of clayey and sandy rocks and are subdivided into three strata: QaS-1, QaS-2, and QaS-3. Sedimentation conditions for all three units of the Qala Suite are similar, only the paleorelief and the amount of transported material differ, which affected the size and location of the formed traps. According to earlier researches, the boundaries for all deposits in the Qala Suite of the field were determined conditionally due to the lack of more detailed seismic surveys at that time.
Characteristic of the scree formation process and influence on the development of floods in Nakchivan Autonomous Republic
Authors: Gurbanov Giyas H. , Mardanov İlham İ. , Gurbanov Ali K.
Published: June 2024

The territory of the Nakhchivan Autonomous Republic has complex geological-geo- morphological and other natural features. The large amount of fall in a very short distance, the diversity in geological conditions and climate elements cause the wide spread of slope processes, including slaking and screen materials. The analysis of researched literature materials, as well as field expedition materials conducted and collected in 2018-2023 shows that the mass of scree materials, as well as their geomorphological characteristics, differ sharply from lowland to highland and from northwest to southeast. For example, while the most erosion was observed on the southwestern slopes of the Kapicik, Gamigaya, Gazangoldag, Yaglidara, Ayichingil, Demirlidag peaks, Eshshekmeydani pass, Kukudag, Kecheldag, Agdaban peaks, avalanche activity was weakly developed on the northern slopes of these peaks. Despite the accumulation of a large amount of alluvial materials in the upper part of the highlands, they hardly participate in the formation of floods. However, in the middle and low mountainous belt, they act as a catalyst for floods. Such danger exists for all river basins of the autonomous republic. However, the fact that the slopes of the northwestern part are less inclined compared to the slopes of the southeastern part significantly reduces this danger. Catastrophic floods in Ordubad, Ganza, and Kotamchay basins have become commonplace every 3-5 years. The activity of slaking and scree formation process and flood formation because of this makes the study of the cause of it an important issue. A geomorphological stress map of the area was drawn up with the joint analysis of the horizontal and vertical division of the terrain, as well as surface inclination angles. At this time, the results of the studies carried out in previous years were analyzed. The square of weak stress area is (1) 1262,622 km2; square of moderately stressed area (2) 1514,791 km2; square of tense territory (3) 1319,102 km2; square of high voltage area (4) 778.4616 km2; The area of the anomalously stressed area (5) is 627,034 km2. The analysis of the map allows us to show the main distribution areas of debris-fall materials, as well as to determine the areas that lead to the development of other dangerous exo dynamic processes such as avalanches, rock falls, landslides, floods, etc.
Cartographic water protection level DRASTIC-index-based modelling of the Senonian aquifer within the boundaries of Poromiv village, Volyn region

Published: June 2024

The research was conducted within the village of Poromiv, Volodymyr district, Volyn region. In the settlement, there are 82 wells intended for drinking water supply, the depth of which varies from 70 to 90 m. Wells reach the Senonian aquifer level. The aquifer has been used for long-term monitoring of water conditions contained in the Quaternary horizon, which in cross-section precedes the Senonian aquifer. The availability of data makes it possible to study the vertical and horizontal migration of chemical elements along the geological profile within the studied territory. By correlation-regression models, which took into account the location factors of the studied wells relative to the main sources of pollution, as well as the peculiarities of the geological and geomorphological structure of the studied territory, we selected 5 model wells. Selected study points represent the chemical composition of groundwater formed within the terrace northwest of the village and south-east of the loess highland. Senonian aquifer waters within the boundaries of the Novovolynsk coal-mining district, to which the village of Poromiv belongs, are characterized by a high content of iron and ammonium ions. Given the fact that we are investigating the economic and household complex of a rural settlement, we determined the phosphate content in groundwater. The general chemical composition of groundwater was also analyzed. The territories with the least protected groundwater horizons were determined using the DRASTIC model. Methods for assessing the vulnerability of groundwater are available in foreign literature. However, in the national literature, a concept of “natural protection” of the considered element of the environment is used. Therefore, during DRASTIC-based calculations,we used the concept of “natural protection” of groundwater. Accordingly, the calculation of scores was carried out from the point of view of assessing the level of protection, not the vulnerability of groundwater. As such, we ascertained insufficient protection of aquifers from technogenic load in the central and north-eastern parts of the village.

Published: June 2024

The article considers the implementation of the ecosystem approach in the implementation of activities related to water use on the South Bug River in the area of the Oleksandrivskyi Reservoir. The relevance of the research topic is determined by the implementation of the Tashlyk Pumped Storage Power Plant construction project related to the increase in the level of the Oleksandrivskyi Reservoir. Methodological principles of ecosystem mapping and assessment of ecosystem services based on MAES ecosystem mapping typology and international classification of ecosystem services to the group level (CICES V5.1). Mapping of ecosystems in part of the South Bug River basin (within Voznesensky district) was carried out and the percentage distribution of the main types of ecosystems was estimated. The main valuable ecosystem services of the Southern Bug River in the area of the Oleksandrivskyi Reservoir are identified as supporting services: biotic (fishery use of the reservoir), abiotic surface drinking water, water for irrigation, water for industrial purposes and energy, regulating and supporting services, including life cycle support, habitat and gene pool protection, food chain preservation, self-purification, as well as cultural services, including rafting, leisure, recreation, whitewater rafting, eco-tourism, sport fishing, education and science. Approaches to its economic evaluation are presented. The results of the assessment of the economic value of the complex of ecosystem services of the Oleksandrivskyi Reservoir are presented, namely: the value of the ecosystem service of providing fish products (calculated by the method of direct monetary valuation), the value of the regulatory service, based on the method of replacing the lost self-cleaning service of the river, as well as the assessment of the cultural ecosystem service by the conditional valuation method by surveying tourist agents. Based on the economic costs of compensating for the assessed ecosystem services, the economic inexpediency of implementing the project to complete the Tashlyk Pumped Storage Power Plant and raise the reservoir level is shown, i.e., such planned activities are environmentally unjustified and unprofitable.
Hydrodynamic mechanism for dynamical structure formation of a system of rotating particles
Authors: Martynov Sergey I. , Tkach Leonilla Yu.
Published: July 2024

Based on the hydrodynamic mechanism, which takes into account the interaction of all particles, a numerical simulation of the formation of a dynamical structure in a viscous fluid was carried out. This structure is a result of the collective dynamics of rotating particles in the fluid. It is supposed that the particles have a magnetic moment and are driven into rotation by an external variable uniform magnetic field. The results of numerical modeling of collective dynamics are presented for three initial structures that can be formed by interacting dipole particles in the absence of an external magnetic field. Such equilibrium structures are a straight chain, a closed chain, and a periodic structure in the form of a flat system of particle chains. The rotation of particles sets the surrounding fluid in motion, whose flow creates hydrodynamic forces and moments that move the particles. The collective dynamics of a system of rotating particles leads to the formation of a new dynamical structure from the original one, and this new structure has its own characteristic features for each case considered. A qualitative comparison of the results of the dynamics for a particles’ system set in motion due to the action of an external moment or an external force is carried out. The proposed hydrodynamic mechanism for the formation of a dynamical structure as a result of the collective dynamics of a rotating particles’ system can be used to control structure formation in a liquid-particle system.
Perkembangan Makna Bahasa Arab

Published: June 2024

Arabic is a language rich in meaning, the richness of meaning of each sentence makes Arabic the language of literature and science. Each word in Arabic can be interpreted with more than one meaning. And Every meaning of an Arabic sentence can change the form by adding meaning, reducing meaning, or changing the structure of the form of the sentence. The nature of the change is a sign of the dynamism of a language resulting from human culture. The development of the meaning of Arabic is due to the existence of Language change as a necessity for the development of thinking, science, and the state of the human being in situations and conditions when interacting that are unlikely to be in the same state. And other factors that cause such changes occur in all linguistic structures of the Arabic language namely phonology, morphology, syntax, semantics and lexicon.

La materia retórica en el «Tesoro» de Covarrubias
Authors: Luján-Atienza Ángel-Luis
Published: July 2024

Debido a su carácter enciclopédico el Tesoro de la lengua castellana ofrece una buena muestra del estado de las diversas disciplinas en la época de su redacción. En este trabajo se estudiará de manera sistemática cómo es tratada la materia retórica en la obra de Covarrubias y cómo este tratamiento corresponde a la realidad de esta disciplina a principios del siglo XVII. En este estudio observamos cómo el proceso de poetización de la retórica es patente en la especial atención que Covarrubias dedica a la elocutio, y se hace un seguimiento de las fuentes que, aparte de ser las clásicas latinas (principalmente Cicerón y Quintiliano), vienen muchas veces mediadas por la obra de Ambrosio Calepino, como ya habían detectado otros estudiosos.
Integration of Genetic Algorithm and Hedge Algebras in controlling mechanical machining robots
Authors: Khoi Phan Bui
Published: June 2024

Robot applications in mechanical processing have become popular. The critical issue when applying robots in mechanical processing is ensuring accuracy. Usually, robot control is based on dynamic models. This method has difficulty accurately determining the system's dynamic model because the robot has a complex structure. Besides, dynamic factors such as cutting force, friction force and machining conditions constantly change. Robot control based on Hedge Algebras gives excellent and reliable results. The critical factors that determine the quality and reliability of the Hedge Algebra controller are the Control Law, the method of Denormalization, and the determination of the Physical Value Domain. The construction of the Control Law and Denormalization is based on expert knowledge. Determining the physical value domain is problematic because it requires many experiments. This article introduces the method of applying genetic algorithms to find the appropriate physical value domain for the controller based on Hedge Algebras. The article presents a robot controller based on Hedge Algebras to do this. Numerical experiments with a mechanical machining robot verify the results.
An E-Learning Innovative Approach for Mathematical Argumentative Thinking
Authors: Albano Giovannina , Iacono Umberto Dello , Mariotti Maria Alessandra
Published: June 2024

This paper concerns the design of a specific computer-based educational environment fostering students’ shift from argumentation to proof in geometry. In particular, we focus on the language difficulties that such a shift might present and on the need for suitable interventions
to overcome them. In this respect, we designed a specific device, named Digital Toolkit for Proof (DTP), based on the use of suitable digital tiles, to promote the transition from colloquial register to literate register, used in mathematical communication. We discuss the findings of the experimentation
involving 14-15 years old students from high school who conjecture and prove within the designed environment. The analysis presented shows how the DTP device can promote the emergence of new formulation of justifications that make explicit references to geometric theory. However, the DTP device
also shows the occurrence of new specific language issues highlighting difficulties hidden by the use of the colloquial register.
(Dis)Continuity and Feedback in Using a Duo of Artefacts for Robust Constructions: The Case of Pre-Service Mathematics Teachers Using Paper-and-Pencil and Dynamic Geometry
Authors: Bozkurt Gülay , Uygan Candas
Published: June 2024

This paper focuses on pre-service mathematics teachers’ geometrical construction processes while using a duo of artefacts, namely the paper-and-pencil environment (PPE) and a dynamic geometry system (DGS). The participants of this case study were two pre-service mathematics
teachers, who had limited DGS experiences in solving geometry tasks. The data were collected through task-based interviews in which the participants were asked to complete angle bisector construction first with PPE and then in DGS, using together with the PPE to support the development of
their construction strategies in DGS. Data analysis was carried out to examine (dis)continuities that the pre-service teachers faced while connecting the duos and the feedback received during such process. Findings indicated that the pre-service teachers had difficulties in comprehending (1)
the concept of robustness of the construction and (2) the dependency relationships between the objects in DGS, which created discontinuities for them to differentiate between a static representation on paper and dynamic representation in DGS. In this, the use of duos and the feedback different
artefacts generated – i.e., direct manipulation feedback, evaluation feedback and tool operation feedback from the DGS, and strategy feedback scaffolded by the interviewer –, promoted their conception of angle bisector construction.
Helpful and Hindering Features of GeoGebra: Understanding What Affords Conceptual Understandings of Definite Integrals Among Pre-Service Middle Grades Mathematics Teachers
Authors: Bullock Emma P. , Webster Joseph S. , Jones Dustin L.
Published: June 2024

This paper introduces the Affording Understanding Conceptual Framework as a way for mathematics teacher educators to analyze student’s perceptions of a digital math tool’s helpfulness (e.g., GeoGebra) versus the instructor’s perceptions when seeking insights into
how a lesson design could be improved. An example of this action research process is provided using GeoGebra to help pre-service middle grades mathematics teachers (MGMTs) develop their conceptual understandings of definite integrals. Findings showed that the pre-service MGMTs noticed four
categories of what they considered to be primarily helpful features: “Ease of Use,” “Pictorial Representation,” “Colored,” and “Slider/Dynamic Movement” types. While the pre-service MGMTs all described these as helpful, the content of their comments
showed that there was a material difference in how they viewed the “Ease of Use” type from the other three suggesting ways in which the lesson could be revised to be more effective.
Computerized Technology as a Tool for Accelerating the Discovery of Geometrical Conservation Properties
Authors: Weissman Shula , Stupel Moshe
Published: June 2024

We present an investigative activity that was set as part of a course of pre-service teachers of mathematics. The emphasis in the course was set on the importance of using the computerized technological tool for teaching the subject. The activity focused on investigating interesting
geometrical conservation properties which are not known to the students, and even to many who study the field. An evaluation was made of the students’ ability to prove these properties using different mathematical tools and to produce generalizations by extending the tasks.
Conquering the LANTITE: Exploring Digital Mathematics Instruction & Test Taking Strategies using a Cognitive Multimedia Framework Based Portal
Authors: Vanderburg Robert M. , Gibson Nicholas , Cowling Michael A.
Published: June 2024

In 2015, all Australian education ministers agreed that from 1 July 2016 the Government would initiate the Literacy and Numeracy Test for Initial Teacher Education (LANTITE), designed to verify that all prospective teachers could demonstrate the literacy and numeracy skills required
in their profession. The LANTITE quickly became another hurdle for educators and could be the most influential gatekeeper ever implemented in Australian Initial Teacher Education (ITE) programs. Institutions, therefore, instigated support programs to help their students pass the LANTITE. This
paper describes once such intervention which is modelled on the Cognitive Theory of Multimedia Learning and is designed for a context where students were placed at a distance and required self-learning approaches. This digital mathematics portal showed a significant improvement in students'
ability to pass the LANTITE. The paper also identifies a set of guidelines for future portals, allowing students to measure their knowledge, using flexible picture and video resources, providing the ability to flexibly absorb content in small chunks, and giving students effective testing strategies
in addition to content knowledge. Future work will look at how these strategies can be implemented and extended, specifically, for students who have a history of failing the test in the past.
Investigation of Effect of Resin Content on the Stress Relaxation of poly (epichlorohydrin-co-ethylene oxide) based Elastomer
Authors: Aksüt Davut
Published: June 2024

In this study, the effect of C9/C10 aromatic hydrocarbon resin (Novares TL 100) and resin amount on the curing and thermo-mechanical properties of poly(epichlorohydrin-co-ethylene oxide) based elastomer mixtures was investigated. In the prepared mixtures, the curing parameters of mixtures that did not contain resin and mixtures containing resin in different proportions were examined. When examining the curing parameters, it was observed that with increasing resin content, the pre-curing time (ts2) and optimum curing time (t90) increased and the curing rate decreased. Moving mold rheometer studies showed that as the amount of resin increased, cross-link formation reactions were delayed or negatively affected. Additionally, temperature scanning stress relaxation tester (TSSR) studies were conducted to evaluate the effect of the resin on the creep behavior, service temperature, and cross-link density of the prepared vulcanizants. TSSR studies were carried out in two stages: first after curing and then after removing the resin from the vulcasinates by soaking the test samples in toluene. TSSR data showed that resin amounts exceeding 5 phr, the creep behavior of poly(epichlorohydrin-co-ethylene oxide) based elastomers, clearly showed that it negatively affects the service temperature and cross-link density.
