Published: March 2023

Background: Myopia, or nearsightedness, affects a large percentage of the population and is typically identified in those under the age of 20. Having myopia makes it difficult to see far away. While you have no issue seeing nearby items, such as those used to indicate aisles in a grocery store, you may have trouble seeing further away ones, such as road signs. Objective: In this study our main goal is to evaluate the distribution of iris colour and its relationship to myopiain Bangladeshi patients. Method: This cross-sectional study was carried out at tertiary hospital from March 2020 to December 2021, researchers from several fields and sessions worked together on a single unified study. There were a total of 100 people, with a best corrected visual acuity (BCVA) of 6/6, and ages ranging from 11 to 25 years old. Patients were limited to no more than six hours of television every day. All three degrees of myopia (mild, moderate, and severe) were covered. Results: During the study, 51% belong to 10-15 years followed by 35% belong to 16-20 years and 14% belong to 21-25 years. In addition, among patients mild 55%, moderate 21%, and severe 24% myopia. Screen time, significantly associated with myopia. 40% who had screen time was 1-2 hours had severe level myopia. Followed by 45% who had screen time was 2-4 hours had severe level myopia and 50% who had screen time was 4-6 hours had severe level myopia. 66% who had mid-level myopia had grade I Irish color. Followed by 56% who had moderate level myopia had grade I Irish color and 50% severe level myopia had grade I Irish color. 66% who had simple myopia had grade I Irish color. Followed by 55% who had curvatural myopia had grade I Irish color. Conclusion: Darker iris color was linked to higher myopia-related refractive errors, even when other known myopia-related risk variables were taken into account.

This study was conducted to evaluate the presence and concentration of Oxytetracycline and Penicillin G residues in raw cow and Fermented milk consumed in Maiduguri, Northeastern Nigeria. A total of 172 (86 raw and 86 fermented) milk samples were randomly collected from different milk selling points in Maiduguri. A Spectrophotometer ultraviolet visible spectrum machine was used to detect and quantify the oxytetracycline and penicillin G residues in the milk samples. All samples (raw and fermented milk) tested positive for oxytetracycline and penicillin G residues with a mean residual concentration of 36 µg/L and 20 µg/L in raw and fermented milk respectively for oxytetracycline while the mean residue concentration of penicillin G is 649 µg/L and 397 µg/L in raw and fermented milk respectively. However, the oxytetracycline residues detected were all below the Maximum Residue Level (MRL) standards of 100 µg/L, while the penicillin G residue detected were all above the maximum residue standard of 5 µg/L. The maximum and minimum residue for oxytetracycline detected in raw milk was 79 and 10 (µg/L) respectively while the maximum and minimum residue detected in fermented milk was 42 and 9 (µg/L) respectively. The maximum and minimum residue detected for penicillin G residue in raw milk was 1993 and 767 (µg/L) respectively while the maximum and minimum residue detected in fermented milk was 288 and 164 (µg/L). This study revealed the presence of both oxytetracycline and penicillin G residues in raw and fermented milk consumed in Maiduguri. However, oxytetracycline residues detected in this study were found to be within the acceptable limits, while the penicillin G residues were highly above the MRL standard set by CODEX.

Published: March 2023

Background: Late-onset Pompe disease (LOPD) is a rare, progressive neuromuscular condition typically characterized by weakness of skeletal muscles, including those involved in respiration and diaphragmatic dysfunction. Individuals with LOPD typically eventually require mobility and/or ventilatory support.

Objectives: This study aimed to develop health state vignettes and estimate health state utility values for LOPD in the United Kingdom.

Methods: Vignettes were developed for 7 health states of LOPD with states defined in terms of mobility and/or ventilatory support. Vignettes were drafted based on patient-reported outcome data from the Phase 3 PROPEL trial (NCT03729362) and supplemented by a literature review. Qualitative interviews with individuals living with LOPD and clinical experts were conducted to explore the health-related quality-of-life (HRQoL) impact of LOPD and to review the draft vignettes. Vignettes were finalized following a second round of interviews with individuals living with LOPD and used in health state valuation exercises with people of the UK population. Participants rated the health states using the EQ-5D-5L, visual analogue scale, and time trade-off interviews.

Results: Twelve individuals living with LOPD and 2 clinical experts were interviewed. Following the interviews, 4 new statements were added regarding dependence on others, bladder control problems, balance issues/fear of falling, and frustration. One hundred interviews with a representative UK population sample were completed. Mean time trade-off utilities ranged from 0.754 (SD = 0.31) (no support) to 0.132 (SD = 0.50) (invasive ventilatory and mobility support–dependent). Similarly, EQ-5D-5L utilities ranged from 0.608 (SD = 0.12) to -0.078 (SD = 0.22).

Discussion: The utilities obtained in the study are consistent with utilities reported in the literature (0.670-0.853 for nonsupport state). The vignette content was based on robust quantitative and qualitative evidence and captured the main HRQoL impacts of LOPD. The general public rated the health states consistently lower with increasing disease progression. There was greater uncertainty around utility estimates for the severe states, suggesting that participants found it harder to rate them.

Conclusion: This study provides utility estimates for LOPD that can be used in economic modeling of treatments for LOPD. Our findings highlight the high disease burden of LOPD and reinforce the societal value of slowing disease progression.

Published: March 2023

Background: Hepatitis C virus (HCV) infection and its treatments are associated with significant symptoms, side effects and impact on patients functioning. The Hepatitis C Symptom and Impact Questionnaire version 4 (HCV-SIQv4) was developed according to FDA Patient Reported Outcomes (PRO) Guidance, for evaluating chronic HCV infection and its treatment. Objectives: This study evaluated the psychometric properties and clinically important change (CIC) thresholds of the measure. Methods: PRO data were pooled from three Phase IIb and III trials evaluating interferon-free simeprevircontaining regimens for treatment of chronic HCV infection. Scale range adequacy, reliability, validity, responsiveness and CIC thresholds were assessed incorporating knowledge of the appropriate measurement model. Results: Data from 437 patients were analyzed. Stage of liver disease was associated with symptom severity and functioning at baseline. Reliability was acceptable (test-retest ICC ≥0.7) for most scores except the Gastrointestinal and Integumentary domains. Convergent validity was observed between HCV-SIQv4 scores and concurrent measures of conceptual similarity. Greater symptom severity and worse impact scores were associated with liver cirrhosis, depression, severe fatigue and health limitations. Patients who achieved SVR12 had better outcomes than those failing to. HCV-SIQv4 symptom and domain scores were responsive to changes in health state (effect sizes ≥0.5). Exploratory thresholds for change in scores indicating a clinically important improvement and worsening were HCV-SIQv4 Overall Body System Score (BSS), 8 and 8; Constitutional BSS, 10 and 10; Gastrointestinal BSS, 5 and 5; Psychiatric BSS, 8 and 8; Neurocognitive BSS, 8 and 8; and Integumentary BSS, 5 and 5. Conclusions: The HCV-SIQv4 offers reliable, responsive assessments within HCV clinical development. CIC thresholds are now available to aid score interpretation.

This article presents a theoretical analysis of the features of modern physical training of future specialists and ways of supporting the motor activity of student youth. It is justified that the activation of students for independent physical exercises should use a variety of innovative physical culture and health technologies, modern forms and methods of learning - integrated classes, interactive forms of learning, the use of information and communication technologies, innovative approaches to assessing somatic health. It has been proven that the effectiveness of students' independent work is quite low, it is accompanied by increased time costs, both of students for its implementation, and of teachers for monitoring its implementation. Methodical support of the educational process plays an important role in increasing the productivity of students, during independent work. Currently, the process of development and introduction into pedagogical practice of a more advanced method of physical education, which covers the physiological, psychological, social and pedagogical aspects and ensures the improvement of the quality of educational work, activates the cognitive activity of students, develops their mental and physical abilities, is of particular importance. At the same time, an important role is assigned to the formation of students' abilities and skills of independent work. It has been established that it is possible to achieve a health-improving effect in the process of independent performance of physical exercises only by observing the main principles: systematicity, gradualness, adequacy and versatile orientation of training.In this way, the proposed technology of training cadets for independent classes in physical culture and health activities should be complex with the use of a large number of means and methods of influencing the personality. Involvement of cadets in independent classes in physical culture and health activities involves the application of a complex of educational influences, the development of a program of classes, the ratio of training tools, the dosage of loads and is a means of forming the need for systematic physical education classes in student youth based on the creation of ideas about a healthy lifestyle.
INTERPRETATION OF THE PHENOMENON OF SPEAKING COMPETENCE IN THE CONTEXT OF A POLYCULTURAL ENVIRONMENT
Authors:   Ferenc Rákóczi II Transcarpathian Hungarian Institute, Chopak Yeva
Published: March 2023

The article examines the question of what multicultural education is and how to introduce it into the higher education system. Interest in multicultural education, on the one hand, is caused by significant social processes, certain shifts in worldview, awareness of the peculiarities and perspectives of time, awareness of the importance of global problems for the fate of civilizations, interaction with modern society, development of value orientations. On the other hand, the discussion of the problem of multicultural education is the result of the modern humanitarian scientific process. In this sense, the analysis of the starting point of multicultural education is one of the most important tasks of the methodology of scientific knowledge. To study the problem of multicultural education, we chose the method of explanation, since explanation is one of the main operations of the subject's cognitive activity. Our research was guided by the fact that the interpretation of culture should take place in a philosophical space. This is because this concept is primarily fundamental in philosophy, and all sub-disciplines of cultural studies are intended to be purely empirical and factual. In addition, philosophy lacks diversity in approaches to the interpretation of culture, since the analysis of culture takes place in a completely different context, that is, to build a theoretical model of culture, or at least to explain its background and preconditions. In particular, we chose a phenomenological direction. Accordingly, we consider culture as a phenomenon. Reflections on culture as a phenomenon led to the desire to direct one's research into a plane containing a specific context of reflection on cultural problems. multicultural education takes place when a specific individual seeks to understand one or another system of values and behavior. Along with understanding the value systems of other cultures, multicultural education involves the imprint of one's own cultural systems. Multicultural education is successful when integration of culturally distinct (different) value systems and cooperation between domestic and foreign cultures is achieved. This interpretation of multicultural education reveals the multifaceted nature of this phenomenon and is characterized by a high degree of interdisciplinary.

Published: March 2023

The prerequisites for the emergence of clipness are clarified: acceleration of the pace of life, development, implementation, spread of ICT, constant growth of requirements for the relevance and speed of receiving, use, storage, assimilation and disposal of information, diversification and increase of multidimensionality, virtuality and access to information, multitasking, commercialization of mass media, activation of communication in social networks, etc. An analysis of the definitions of “clip” and “blip” was conducted and it was proposed to consider them as synonyms. The negative (loss of desire to learn new things; fragmentation, inconsistency of thinking style and way of life; inconsistency and inadequacy in decision-making; reduced reflection; susceptibility to manipulation and influences; reduced ability to analyze and synthesize; anti-intellectualism and plagiarism; mass ignorance of young people and the phenomenon of proud enthusiasm by one’s own ignorance; absolute conviction of one’s rightness; “virtual drug addiction” and Internet addiction; lack of rational principles and clear logic, haste in conclusions, formation of mosaicism, and fragmentation of perception and impressions; violation and denial of any rules and norms; language minimalism, etc.) and positive (develops creative abilities; contributes to the formation of the body’s protective reaction to information overload; is one of the forms of human-information relations; gives dynamism to the epistemological component of human activity and opens up new perspectives for it; enables multifaceted, multivariate, multidimensionality, multitasking, etc., causes an ambiguity of approaches, gives rise to an informationally adapted personality; replenishes the language with new words and expressions; promotes mobility and sociability, expands freedom of choice, independence of a person, etc.) features of clipness. It is noted that ICT addiction leads to depression, suicide, sleep disorders, and cyberbullying. The iGen has been found to: feel unhappy, lonely, not growing up, not dating, less sexually active, not driving, not working, etc. The “clip” type of consciousness and thinking is analyzed compared to the norm, anomie and genius. It is emphasized that for modern society, “clipness” is the norm and a manifestation of genius, because Learners (Students) and Teachers are interested in constant changes, quickly react to the demands of the labor market, as well as development and implementation of innovations when information prevails.

The development of Ukraine and its integration into the European space have a significant impact on the educational policy and practice of our state. This especially applies to ensuring the right of children with special educational needs to study. Therefore, one of the priority directions of the development of the national education system is the search for effective ways of including children with special educational needs in the educational environment, ensuring their socialization and social integration. Insufficient attention is paid to finding effective ways to include preschool children with special educational needs in an inclusive educational environment to ensure their socialization and social integration. Taking into account the fact that the preschool education institution is the first link of education in Ukraine, within which the socialization of the child is carried out, it is important to understand the peculiarities of the social integration of the preschooler in the general educational space and to apply scientifically based, effective and age-appropriate means of social integration to ensure it. The article analyzes general and special psychological and pedagogical literature on the concept of "social integration"; the essence of the process of social integration of children of younger preschool age with general underdevelopment of speech is determined. The criteria and indicators of social integration of children of younger preschool age are substantiated, the methodology of researching the level of social integration of children of the specified age group is described, the features of social integration of children of younger preschool age with general underdevelopment of speech are outlined on the basis of a qualitative analysis of the results of a diagnostic study regarding each of the competencies of children of younger preschool age, and also compared the level of social integration of children of younger preschool age with typical development with the level of social integration of children of younger preschool age with general underdevelopment of speech.

Published: March 2023

The article highlights the organization of self-directed learning of chemistry among pupils as one of the ways to enhance education quality in the conditions of distance learning. Today’s education aims to provide equal conditions and access to quality education to all. In this regard, it is crucial to organize self-directed learning which depends on both the pupil’s personality and the elements of the external system. The article specifies the teacher’s main objectives in terms of managing self-learning: a) to involve pupils in independent cognitive activities; b) to provide emotional support for pupils; c) to create a winning situation by applying individual assessment standards, as well as enabling examination of the obtained results by both the teacher and the pupils. Besides, the article formulates the principles for self-directed learning of chemistry among pupils: self-determination, openness, links between self-learning and practice, visualisation, proactivity, adaptability and interactivity. Importantly, one should take into consideration the specifics of the subject itself. It refers to the scale of the material, abstractness, as well as the leading role of tasks. The main components of managing self-directed learning of chemistry are as follows: “the system of problems” (a set of specially selected chemistry problems, standard and non-standard both in terms of solution and content) and “the level of independence” (how involved the pupils are in determining the goal and choosing the ways to achieve it). A detailed analysis of how today’s education develops and is updated allows one to discover the conditions for effective self-directed learning of chemistry among pupils. They are the following: focusing on the creative nature of educational activity; building individual educational paths; using the latest technologies under the needs of the educational process. Finally, the article clarifies the three levels of managing self-directed learning of chemistry among pupils: internal management (following the curriculum); internal self-management (following the pupil’s internal motives); external management (performed by the teacher in case of supplementing and correcting internal management).

A solid financial plan considers all the variables that can affect your financial future, such as your current income, savings, expenses, and expected future income. So you try to match your savings and investment decisions with your long-term and short-term financial goals. Financial planning is crucial when it comes to saving taxes. We should have a stable savings rate because the financial markets always oscillate between inflation and deflation. Financial planning is not adequate without considering tax implications.Effective tax planning can reduce our tax burden. Taking advantage of all tax breaks, allowances, returns and exemptions while ensuring that your investments match your long-term goals is the best way to do this.

Authors: Kullian Neema C. , Ally Juma S. , Magemo Award
Published: March 2023

Postnatal care (PNC) refers to the care given to the mother and the newborn from the time of delivery until six weeks of age. Despite attempts, postnatal care (PNC) delivery still falls short of meeting mothers’ and newborns’ needs. With approximately 90% of mobile phone users coming from underdeveloped nations, there is more room for improved maternal and neonatal health interventions. With the aid of mobile technologies, this study attempts to boost PNC adoption. Studies showed that the case study area, Tanzania, had little evidence of PNC intervention frameworks and mobile applications. First, it was determined which factors affected how well health systems handled postpartum care (PNC). Data were gathered from health facilities at every level in Mbeya, Tanzania. Following the examination of descriptive statistics, postpartum women had lower levels of satisfaction with the advice given to them by healthcare professionals regarding clinical attendance (mean = 2.81). After giving birth, postpartum mothers who remained in the medical centre longer had an 85% lower likelihood of being happy with the health system. Higher educated postpartum women had less favourable sentiments about PNC delivery. The findings pointed to the necessity of raising PNC awareness in order to enhance both health worker performance and the well-being of a mother and her newborn. These findings were used to create a framework that also included PNC performance indicators from the WHO and services that might help the mother and the health worker. Using JavaScript’s React native technology and the SQLite database engine, the Afya Mama mobile application was created. This study is of considerable importance to communities in Tanzania as a whole as it improves the uptake of PNC
Optimal Placement of PMUs in Smart Grid for Voltage Stability Monitoring using AMPSO and PSAT
Authors: Babu Palepu Suresh , Reddy Dr. M Damodar
Published: March 2023

Efficient energy use is critical for a growing nation like India. The smart grid (SG) idea enables the creation of a highly dependable electricity system that optimizes existing resources. The Indian electricity grid as it now exists needs fundamental modifications to satisfy increasing demand and to make the system more intelligent and dependable. Since the past several decades, power system stability has been seen as a significant challenge to power system researchers and utilities. With a not many strategically placed Phasor Measurement Units (PMUs), it may be feasible to observe the power system stability of the network. This article suggests an optimum location for PMUs, considering the effect of power system stability-related serious situations. The disturbances have been prioritized according to their voltage stability boundary (the gap among the stand case working and nose points). Changes in the voltage stability tolerance due to shifting load conditions were also considered in the crucial contingency determination. PMUs were inserted in the system based on Adaptive Mutated Particle Swarm Optimization (AMPSO) findings for the intact system and crucial contingency scenarios on the basis of voltage stability. The effectiveness of the suggested PMUs placement strategy was determined by examining nose curves produced with PMUs data and pseudo-observations under increasing demands to nose curves calculated offline using continuation power flow data. Using the software tool Power-System Analysis Toolbox (PSAT), case studies were conducted on a conventional IEEE14 bus system and a realistic 246 bus Indian Power Grid system.
ISM Band 2.4 GHz Wearable Textile Antenna for Glucose Level Monitoring
Authors: Ghodake Asha , Hogade Balaji
Published: March 2023

Wearable technology has recently attracted much interest for various uses. An essential component of the wearable system is the wearable antenna. Textile and non-textile materials have both been used to create wearable antennas. Textile antennas are very useful and widely used nowadays, particularly in body-worn applications monitoring health parameters. Fabricated using microstrip technology, textile antennas have various benefits, including small size, lightweight, simple fabrication, and ease of wear. In this study, a microstrip antenna is created utilizing a substrate made of jeans. It works between 2.4 to 2.5 GHz in the ISM (industrial, scientific, and medical) band. High-frequency structure simulator (HFSS) software was used to simulate two antennas, one with an incomplete and the other with a complete ground plane. Wearable antennas can protect the body from the impacts of RF radiation by utilizing the entire ground plane principle. Results from a vector network analyzer were obtained for the fabricated antenna (VNA). This antenna's main function is to track blood glucose levels. Blood's dielectric characteristics change when blood sugar levels fluctuate, affecting the antenna’s output frequency. There are two ways to monitor glucose levels. One method requires placing a finger on an antenna patch, while the other involves fixing an antenna to a person's arm and detecting the output frequency fluctuation. The antenna's resonant frequency raises in reaction to increased blood glucose levels. Therefore, these textile antennas are a great choice for non-blood sample monitoring of blood glucose levels.

Brushless DC (BLDC) motors have a wide range of applications in these modern days, such as electric vehicles, industrial robots, washing machines, pumps, and blowers. The brushless DC motors have many advantages when compared to induction motors and conventional DC motors, such as better speed control, noiseless operation, high efficiency, less maintenance, and a long life. Along with these benefits, there is one major disadvantage known as cogging, which causes undesirable effects in the motor such as noises and vibrations. BLDC motors have been widely used in automation and industrial applications due to their attractive features. There are certain parameters to be considered while designing a BLDC motor, such as its dimensions, number of windings turns, type of magnetic materials used, required torque, output current, slot-to-depth ratio, efficiency, temperature rise, etc.

Uso de Anticonvulsivantes Profiláticos na Hemorragia Subaracnóide: Existe um Padrão?
Authors: Marcondes Freitas João Ricardo , Martins de Araujo Marcio
Published: March 2023

A hemorragia subaracnóide aneurismática (HSA) é considerada causa importante de morte e sequelas neurológicas. A taxa de mortalidade desta doença pode alcançar 50% nos primeiros dois meses após sangramento do aneurisma encefálico. Apesar dos avanços científicos o resultado do tratamento não mudou nos últimos anos. Os medicamentos anticonvulsivantes são utilizados rotineiramente para tratamento profilático em pacientes vítimas de HSA. De acordo com a pesquisa ministrar anticonvulsivante antes da realização cirúrgica em pacientes de baixo risco, em curto prazo, pois seu uso contínuo apresenta efeitos colaterais, demonstra efetividade. Porém não há evidencias suficientes para justificar sua utilização na prevenção primária e secundária de convulsões após uma hemorragia subaracnóide. A heterogeneidade fisiopatológica dos pacientes afetados pela HSA, a ausência de investigações farmacocinéticas satisfatórias para avaliar doses ótimas, e o momento para a administração reforçam a necessidade de mais estudos para se traçar um modelo pré-clínico terapêutico.

A microbiota intestinal tem sido alvo de muitos estudos, principalmente pela relação que estabelece com a homeostase do organismo. A disbiose desses microrganismos está associada a distúrbios metabólicos como diabetes, dislipidemia e obesidade. A obesidade é um dos grandes problemas de saúde pública devido a suas comorbidades, e as cirurgias bariátricas apresentam-se como alternativa terapêutica para essa condição. Métodos: Foi realizada revisão sistemática nas bases de dados Pubmed, Scielo e Lilacs em artigos originais utilizando os descritores: bariátrica/ cirurgia bariátrica, e, microbiota/ microbioma/ bacteria/ flora e seus sinônimos em inglês e espanhol. Resultados: de um total inicial de 1387 artigos, 8 foram utilizados para esse estudo, por serem condizentes com a proposta aventada. Conclusão: As cirurgias bariátricas modificam a microbiota intestinal principalmente em relação ao Filo Proteobacteria. São necessários novos estudos clínicos acerca do tema de modo a se estabelecer a influência e modificação de microbiota pós cirurgia bariátrica.

Published: March 2023

Gehäuse aus der hochfesten Aluminiumlegierung EN AW-7075 versprechen eine Leistungssteigerung von paraffinbasierten Dehnstoffaktoren (DSA). Gegenüber Stahlgehäusen folgt eine höhere Wärmeleitfähigkeit und somit verkürzte Reaktionszeiten. Der geringere E-Modul und die höhere Elastizitätsgrenze vergrößern zudem die Stellwege. Diese Eigenschaften werden anhand numerischer Untersuchungen überprüft. Eine Ergebnisvalidierung sowie eine Diskussion der Herausforderungen in der Fertigung werden ebenfalls diskutiert.

 

Housings made of high-strength aluminum alloy EN AW-7075 suggest an increase in the performance of paraffin wax phase change actuators. Compared with steel housings, this results in higher thermal conductivity and thus shorter response times. The lower Young‘s modulus and the higher yield strength the more the actuator stroke will increase. These properties are verified by numerical investigations. A validation of results as well as a discussion of challenges in manufacturing are also presented.

Published: March 2023

Bei der Serienproduktion von Blechbauteilen können schwankende Blecheigenschaften zu zeitintensiven Anlaufphasen und erhöhten Ausschussraten führen. Ein Lösungsansatz, um diesen Herausforderungen zu begegnen, besteht in der Veränderung der Platinenlage vor dem Umformvorgang. Vor diesem Hintergrund wird in diesem Beitrag der Qualitätseinfluss der Platinenlage auf das Tiefziehergebnis untersucht. Hierfür wurden experimentelle sowie numerische Untersuchungen durchgeführt, um den Einfluss der Platinenlage auf das Umformergebnis bewerten zu können.

 

In series production of sheet metal components, fluctuating sheet metal properties can lead to time-consuming start-up phases and increased scrap rates. One approach for overcoming these challenges is to change the blank position before the forming process. Against this background, this paper investigates the quality influence of the blank position on the deep-drawing result. Experimental and numerical investigations were carried out to evaluate the influence of the blank position on the forming result.

Reduktion der Krümmung bei rollgeformten Profilen/Improved straightness for roll-formed profiles - Reduced profile defects due to partial rolling
Authors: Güngör Burcu , Kilz Johannes , Groche Peter
Published: March 2023

Ein wesentliches Qualitätsmerkmal von rollgeformten Profilen ist deren geometrische Exaktheit. Die Schwierigkeit liegt folglich in der Vermeidung von Profilfehlern, die bei Rollformprozessen aufgrund des erfahrungsbasierten Rüstvorgangs häufig auftreten und die Profilqualität wesentlich beeinflussen. Diese Arbeit zeigt numerisch und experimentell, wie sich die Dehnungsverteilung durch partielles Auswalzen des Profilbodens verändert und wie sich dadurch Profilfehler reduzieren lassen.

 

An essential quality feature of roll-formed profiles is their geometric accuracy. Therefore, it is difficult to avoid profile errors, which frequently occur in roll forming processes due to the experience-based setup process. This paper shows both numerically and experimentally how partial rolling of the section bottom changes the strain distribution and how profile errors can thus be reduced.
