A Case Report on Damage to School Buildings During the 2015 Nepal Earthquake and Reconstruction Strategy
Authors: Paudyal Youb Raj , Bhandary Netra Prakash
Published: June 2023

The 2015 Nepal Earthquake (Mw7.8) affected more than 9,000 schools in the country. Damage distribution in the 14 most-affected administrative districts shows that the construction practices were an important determent for the level of damage extended. Use of improper construction materials, lack of construction supervision, and non-compliance with the existing building codes during design and construction probably contributed to the severe damage of most of the school buildings. Preliminary damage assessment results show that in the most-affected districts, about 86% schools were affected by the earthquake and about one million students were out of their schools for a long time. The damage survey data indicate that about 30% classrooms collapsed, about 13% classrooms sustained major damage, and about 17% classrooms sustained minor damage within the 14 districts. Such evidence of loss and damage in the earthquake disasters provides an opportunity to learn lessons for the future preparedness and to encounter the disaster challenges. Based on the damage analysis data and experience of reconstruction process after the 2015 Nepal Earthquake, this paper highlights the steps to be considered during reconstruction strategy planning for school buildings after an earthquake disaster.

Published: June 2023

Gamification, which is the implementation of game elements in non-game situations such as the educational sector, has received its popularity in recent years due to its positive impact on the teaching and learning process. The manipulative nature of gamification is often criticized as it traps students in a reward loop, diminishing the positive effect as time elapses. However, major studies ignored the depth of gamification and thus, the purpose of the study is to identify the effect of gamified depth on students’ intrinsic motivation and performance levels. This study uses a quasi-experimental approach that involves a total of 117 undergraduate students separated into control (n=57) and experimental (n=60) groups. Then they are exposed to two gamified platforms, Kahoot! for shallow gamification and Classcraftfor deep gamification respectively throughout 4 weeks. The study utilizes the Intrinsic Motivation Inventory (IMI) to measure the changes that occur within students’ intrinsic motivation level over the study and an achievement test is given at the final lesson. T-tests and regression analysis were used to test the hypothesis of this study. The results showed that deep gamification does increase learners’ intrinsic motivation level, but shallow gamification decreases. Anyhow, students who use the shallow gamified learning environment have a higher performance than those in a deep gamified environment. Students’ language mastery, interest, attitude, and familiarity with technology are presumed to affect the outcome of the studies. Distinct subjects and age groups are recommended for future studies to develop a proper gamified depth framework in the educational sector.

The thermometric video image (VTM) can guide the search for distant metastases, once the vascular architecture is known, identifying, by segmentation, the tumor thermal impression and a similar pattern at a distance. Thus, suspicious areas can be better investigated, improving the postoperative prognosis. In this study, it was possible to observe the assertive capacity of video thermometry in identifying distant metastases and breast tumors in female dogs, not palpable or visible to the naked eye, in relation to conventionally used techniques. It was also possible to identify textures with anatomical limits, from emboli to early formations of carcinomas, adenocarcinomas and adenomyoepithelioma. It was also possible to find non-neoplastic changes such as dermatitis, lipoma, hyperplasia and breast cysts. it can be concluded that the video thermometry (VTM) technique was capable of identifying distant metastases from the primary tumor and other benign alterations with great precision. However, for this to be possible, it is essential that the processing be carried out by SaMD (Software as a Medical Device), with tools capable of identifying patterns and thermal signatures, just like the algorithm, thus increasing the efficacy of the technique.
Mathematical modeling of neuro-immune processes in epileptogenesis
Authors:   , Batulin Danylo
Published: June 2023

This thesis presents a first-of-its-kind phenomenological framework that formally describes the development of acquired epilepsy and the role of the neuro-immune axis in this development. Formulated as a system of nonlinear differential equations, the model describes the interaction of processes such as neuroinflammation, blood- brain barrier disruption, neuronal death, circuit remodeling, and epileptic seizures. The model allows for the simulation of epilepsy development courses caused by a variety of neurological injuries. The simulation results are in agreement with ex- perimental findings from three distinct animal models of epileptogenesis. Simula- tions capture injury-specific temporal patterns of seizure occurrence, neuroinflam- mation, blood-brain barrier leakage, and progression of neuronal death. In addition, the model provides insights into phenomena related to epileptogenesis such as the emergence of paradoxically long time scales of disease development after injury, the dose-dependence of epileptogenesis features on injury severity, and the variability of clinical outcomes in subjects exposed to identical injury. Moreover, the developed framework allows for the simulation of therapeutic interventions, which provides insights into the injury-specificity of prominent intervention strategies. Thus, the model can be used as an in silico tool for the generation of testable predictions, which may aid pre-clinical research for the development of epilepsy treatments.

Background: Intravenous immunoglobulin (IVIG) replacement therapy is increasingly in demand. This study focused on the characteristics of IVIG usage and associated factors toward the frequency status of IVIG among patients in Hospital Kuala Lumpur. Methods: A retrospective cross-sectional study was performed on patients who received IVIG in Hospital Kuala Lumpur. Data were extracted from the request forms for IVIG recorded in the Pharmacy Department from January 2018 until December 2019. Chi-squared test and t-test analysis were used for statistical analysis, and a P-value of < 0.05 was considered significant. Results: A total of 482 patients received IVIG in Hospital Kuala Lumpur. There were 243 (50.4%) females and 228 (47.3%) males with median age of the patients was 27 years old. The highest indications for IVIG among all patients were hypogammaglobulinemia and other deficiency states in 127 patients (26.3%). The most common indication for one-off treatment in adults was hypogammaglobulinemia and other deficiency states, 35%; whereas in paediatrics, it was Kawasaki disease, 20.3%. The highest indication for regular therapy among adult patients was chronic inflammatory demyelinating polyneuropathy (23.4%), while in paediatrics it was sepsis (31.1%). The clinical category was associated with the frequency status of IVIG usage in both adult and paediatric cohorts with P = 0.004 and P = 0.017, respectively. Conclusion: There were significant differences between the indication of one-off treatment and regular therapy among adult and paediatric patients. A national guideline on the prescription of IVIG for patients is instantly needed to help clinicians in prescribing IVIG appropriately.

Background: Low back pain (LBP) is a common musculoskeletal disorder that affects people of all ages. This study investigates the effects of the addition of hands-on procedures to McKenzie exercises on patients with LBP and derangement syndrome. Methods: Forty-eight female patients were randomly assigned to either the experimental group or control group. All the patients in both groups underwent McKenzie exercises, transcutaneous electrical nerve stimulation (TENS) and education for 35 min/session–45 min/ session, with three sessions/week for 2 weeks. Hands-on procedures were added to the McKenzie extension exercises only for the patients in the experimental group. A visual analogue scale (VAS), the Oswestry disability index (ODI), back range of motion (BROM) and body diagrams were used to measure pain, functional disability, BROM and the centralisation of symptoms, respectively. Results: The mean values of VAS, ODI and BROM significantly improved after the interventions in both groups (P < 0.05), whereas the results of repeated measures ANOVA and Mann-Whitney U tests showed statistically non-significant differences between the two groups (P > 0.05). Conclusion: The addition of hands-on procedures to McKenzie exercises, TENS and education significantly alleviated back pain and functional disability and improved the back mobility and centralisation of symptoms in patients with LBP and derangement syndrome; however, these measures did not result in any significant additional benefits for such patients.

Background: Regular physical activity and proper nutritional intake are crucial for bone health. However, it is unclear if this health benefit is maintained after the removal of these stimuli. This study investigated the combined effects of aerobic dance exercise and honey supplementation, followed by their subsequent cessation on bone metabolism markers and antioxidant status in females. Methods: Forty-eight young female college students were assigned into four groups: i) 16S (16 weeks of sedentary activity); ii) 8E×8S (8 weeks of exercise followed by 8 weeks of sedentary activity); iii) 8H8S (8 weeks of honey supplementation followed by 8 weeks of sedentary activity) and iv) 8E×H8S (8 weeks of combined exercise and honey supplementation followed by 8 weeks of sedentary activity). Blood samples were collected from the participants prior to the intervention, at week 8 and at week 16 for the analysis of bone metabolism markers and antioxidant status. Results: At the mid test, bone speed of sound (SOS) (P < 0.01), serum alkaline phosphatase (ALP) (P < 0.001) and serum osteocalcin (P < 0.01) were significantly higher in the 8E×H8S group as compared to 16S group. After 8 weeks of cessation of exercise and honey supplementation, bone SOS was also significantly higher (P < 0.001) in the 8E×H8S group as compared to 16S group. In addition, the serum total calcium (P < 0.001), serum ALP (P < 0.01), total antioxidant status (TAS) (P < 0.01) and glutathione (GSH) (P < 0.01) in the 8E×H8S group were significantly higher at the post-test as compared to their respective pre-test values. Conclusion: These findings demonstrate that there was improved maintenance of the beneficial effects induced by 8 weeks of combined exercise and honey supplementation on bone properties and the antioxidant status after 8 weeks of cessation of exercise and honey supplementation as compared to exercise and honey supplementation alone.

Background: Tuberculosis (TB) is a communicable disease which contributes to a major cause of ill health. Worldwide, it is one of the leading causes of death from a single infectious agent. Objectives: The study aimed to describe the epidemiology and factors associated with TB mortality in Manjung district, Perak, Malaysia. Methods: All confirmed TB cases from 2015 to 2020 registered in Manjung district under Sistem Maklumat Tibi (MyTB) were included. Factors associated with TB mortality were analysed by using simple and multiple logistic regression analysis. Results: A total of 742 TB cases were included in the analysis, from which 121 cases (16.3%) died before completing their treatment. The highest death was reported in 2020 (25.7%) and the lowest in 2019 (12.9%). From multiple logistic regression analysis, age 45 years old–64 years old (adjusted OR = 3.62; 95% CI: 1.38, 9.54), > 65 years old (adjusted OR = 8.67; 95% CI: 3.17, 23.74), non-Malaysian (adjusted OR = 5.18; 95% CI: 2.04, 13.14), cases notified by government hospitals (adjusted OR = 6.78; 95% CI: 3.04, 15.09), HIV-positive status (adjusted OR = 8.60; 95% CI: 3.58, 20.67) and HIV testing not offered/unknown (adjusted OR = 2.58; 95% CI: 1.18, 5.62) were significantly associated with TB mortality. Conclusion: This study found that TB patients who were 45 years old and above, positive HIV, late diagnosis and are foreigners had a higher risk for TB mortality. Early diagnosis, optimised screening and close monitoring should be practised to reduce TB mortality.

Essential thrombocythemia is a form of myeloproliferative syndromes, essentially characterized by the frequency of thrombotic, hemorrhagic and vasomotor complications. Despite the rarity of myocardial infarctions resulting from this pathology, the prognosis remains pejorative given the complexity of the therapeutic management. We report the case of a 70 years old patient with cardiovascular risk factors: well-balanced diabetes, untreated dyslipidemia, and obesity. Admitted for the management of an acute coronary syndrome with anterior ST segment shift overextended at H7 of pain, thrombolysis at H8 with failure. Not initially explored given the high thrombotic and hemorrhagic risk, linked to a thrombocytosis at 1200000/mm3 discovered fortuitously. An etiological assessment was launched confirming essential thrombocythemia, and the patient was put on an antiplatelet agent and a cytoreducer. Coronarographic exploration was recommended after the significant reduction in the platelet count, objectifying an angiographically normal coronary network. The diagnosis of myocardial infarction on resolved thrombus complicating essential thrombocythemia was retained. In the light of this observation, we discuss the difficulties of management related to this pathology and we expose our experience for the management and attenuation of the thrombotic and hemorrhagic risk.

Patient-specific implant (PSI) is a personalized approach to reconstructive and esthetic surgery. This is particularly useful in maxillofacial surgery as well as prosthodontics, in which restoring the complex three-dimensional (3D) contour can be quite challenging. In certain situations, the best results can only be achieved with implants custom made to fit a particular need. Among the various alloplastic materials, polyether-ether ketone (PEEK) has emerged as an attractive option for the PSI. Significant progress has been made over the past decade in the design and manufacture of maxillofacial PSIs using additive manufacturing (AM) technology. This paper gives a brief review of Patient Specific Implants, its manufacturing, indications and materials used in maxillofacial surgery.

Published: June 2023

The goal of the research was determination of the level of annual tritium intake in the air from coastal plants of Lake Kyzyltash in 2021 and compliance of tritium content in the air of the coastal area of Lake Kyzyltash in 2021 with radiation safety standards. In the period May-September, 2021, a study of coastal plants near Lake Kyzyltash, a technological reservoir of the Mayak Production Association, was conducted. Within 100 m from the lakeside, humidity level of plants ranged from 41% to 87%, tritium volume activity level in the water of plants and transpiration water varied from 96 Bq/l to ~8.0 kBq/l and from 64 Bq/l to ~9.0 kBq/l, correspondingly. Based on the Cheddock scale, rank correlations between tritium volume activity and: time from the beginning of a vegetation period (weak reverse); distance from the lakeside (marked reverse); humidity of the plants (moderate positive), were revealed. To predict tritium intake in the air in the form HTO during the post-vegetative period, exponential decrease models of humidity and tritium volume activity in the plants with time were developed. The estimates of general periods of semi-decrease in humidity and tritium volume activity in the water of the plants, were 262 and 64 days, correspondingly. Total annual HTO intake in the air in 2021 from coastal plants was 6.92 E+11Bq, with contribution 0.35% of annual tritium intake from Lake Kyzyltash surface. The plants from the zone 0…~5m contribute 81.8% of total annual intake from coastal plants of Kyzyltash Lake (5.66E+11Bq). Annual HTO intake from the plants of Lake Kyzyltash coastline (0…~5m) only, was 5.66E+11Bq and was consistent with tritium release in 2021 from the Kursk Nuclear Power Plant (5.32E+11Bq), and tritium intake from all coastal plants of Lake Kyzyltash – with release from the Leningrad Nuclear Power Plant (6.90E+11Bq). In the course of two expeditions, if there were no precipitations, the mean HTO volume activity in the air of Lake Kyzyltash coastal areas was ~60 Bq/ m3, which is ~30 times less than permissible volume activity in the inhaled air for population 1.9E+3Bq/m3,according to NRB-99/2009. In the case of a hypothetical residence on the lakeside of Lake Kyzyltash in 2021 and a permanent level of tritium volume activity in natural environments, an annual committed effective dose of internal radiation conditioned by inhalation of super-heavy water vapor, will be 31 μSv/year for a critical group of children aged 1-2 years and 8.7 μSv/year for adult residents, according to NRB-99/2009. These estimates are conservative as far as they do not take into account the ice-free period during which there is practically no evaporation of water from Lake Kyzyltash surface and intake from plants.

The Quality Index Method (QIM) provides a quick and accurate quality assessment. It makes it possible to calculate preserving time and establish the freshness of sea food. This article introduces a quality assessment program based on the QIM scheme and quality index (QI) for the Jinga shrimp.

The research included Jinga shrimps (Metapenaeus affinis L.), a commercially valuable aquatic species widely distributed throughout the Vietnamese coast. The input data included the changes in appearance and sensory profile of sampled shrimps during 20 days of storage at 0–4°C in ice water.

They were used to construct a QIM scale, which was applied to other shrimp samples at different storage time to evaluate the relationship between the QI score and the storage time. After that, the QIM scale was tested on ten random shrimp samples to verify its shelf-life predictive power. This study managed to establish a correlation equation between the QI scores and the storage time with the coefficient of R2= 0.97. This correlation proved highly reliable as verified by comparing the predicted and actual best shelf life of Jinga shrimps stored in ice water for 8–10 days.

The QIM program provides a practical and effective science-based tool that delivers fast and reliable results for customers, fishermen, food traders, and aquacultural enterprises.

Authors: Saldivia Paredes Manuel Alexis , Yaeger Jaramillo Paz Lourdes
Published: June 2023

La rodilla es una de las articulaciones sinoviales más grandes del cuerpo y una de las más complejas en su morfología y biomecánica. Se constituye por el punto de contacto de estructuras óseas, cartilaginosas, ligamentosas, vasculares y musculares que al funcionar de manera integrada permiten otorgar una capacidad extensora, flexora y leve rotación. El equino se caracteriza por disponer de un mecanismo de bloqueo patelar conocido como sistema recíproco patelar, la cual tiene como finalidad permitir generar una resistencia patelar al momento de ser posicionada, generando una mayor distribución del peso corporal a nivel de la articulación fijada, lo cual permite que la otra extremidad pélvica pueda descansar en una posición de relajación y semiflexión del pie. El objetivo del siguiente estudio fue realizar una descripción morfológica de las estructuras anatómicas macroscópicas, que participan en la conformación de la articulación de la rodilla del equino y como ellas pueden permitir una funcionalidad biomecánica particular. Para ello se realizaron disecciones de ocho rodillas de equinos conservados y las descripciones óseas fueron de diez rodillas ya trabajadas por medio de osteotecnia en el laboratorio de anatomía veterinaria, de la Universidad San Sebastián, sede de la Patagonia.

Published: June 2023

Los ambientes de producción animal presentan factores que afectan directa o indirectamente las condiciones de vida, nutrición, reproducción o el crecimiento de diferentes especies animales, así como propicia el desarrollo bacteriano dando lugar a infecciones por microrganismos de importancia mundial en salud pública, como lo es Escherichia coli bacteria con potencial de virulencia y resistencia que conllevan al difícil control y tratamiento en producción, y a la circulación de cepas entre especies animales y el hombre. El objetivo de la revisión fue describir genes de virulencia y su patogenicidad expresados por Escherichia coli, que circulan con mayor prevalencia en los ambientes de producción en diferentes especies animales. Se realizó una revisión sistemática de la literatura en las bases de datos Medline, Lilacs, ScienceDirect, PubMed, Acopas, SciELO y Dialnet, se realizó una búsqueda utilizando una combinación de palabras claves validadas en español e inglés (gen, Escherichia coli, food chain, animal production, virulence, poultry, pathogenicity, cattle diseases, microbial drug resistance). Se identificó que las variaciones de Escherichia coli (serotipos) presentan mecanismos de virulencia relacionados con la generación de patologías graves en animales jóvenes como la producción de colibacilosis con altos potenciales en la producción de toxinas, adhesinas y citotoxinas encargadas del daño celular, muerte y pérdidas económicas a los productos; debido a ello las medidas preventivas toman un papel fundamental en el cuidado de los animales para la generación de productos con calidad e inocuidad.

This paper aims to assess the psychometric quality of the Spiritual Intelligence Self-Report Inventory (SISRI), a scale adapted to measure leaders' spiritual intelligence (SI) from the perspective of Brazilian and Portuguese workers. This scale initially measures an individual's spiritual intelligence, and its adaptation opens up the opportunity to perceive the leader's SI from the point of view of his work team. In order to compare possible cultural differences, the research was carried out in hospital organizations in two countries: Brazil and Portugal. The Total sample is 434 workers. The statistical results indicate that the adapted SISRI is a reliable instrument that can measure the leader's spiritual intelligence. The four-factor structure is supported, as well as the construct´s invariance and convergence are maintained. As for cultural differences, it was observed that Brazilian workers have higher scores in the leader's total spiritual intelligence score, specifically in the Existential Critical Thinking (CET) and Awareness Expansion (CSE) dimensions.

El brillo del planeta Venus, el tercer objeto más brillante después del sol y la luna, empezó a notarse en el firmamento. Parecía una tarde cualquiera, 25 de agosto de 1609. El sol comenzó a declinar y la noche a surgir. Galileo estaba emocionado, lo único que quería era apuntar su telescopio hacia el cielo y seguir aprendiendo acerca de la revolución de las esferas celestes. Estaba convencido de que el universo era mucho más impresionante de lo que aparecía delante la experiencia ordinaria.
Galileo Galilei (1564-1642) era consciente de las limitaciones de su visión natural; sin embargo, tenía claro que su mente no estaba encadenada al entorno. Sabía que podía agudizar la mirada con el telescopio, instrumento que se convirtió en el medio para acceder a un mundo nunca visto. Un universo que siempre había estado frente a sus ojos, pero que había permanecido oculto hasta el momento.

Lack of proper handwashing by healthcare providers is the major vector for the spread of nosocomial pathogens in healthcare settings. A cross-sectional study was conducted among 128 community healthcare providers (CHCPs) in the Kurigram district of Bangladesh to investigate predictors of handwashing before and after clinical care encounters. Data were collected between November and December 2019 via a paper-and-pen based survey using a semi-structured questionnaire. CHCP's pre-care handwashing with soap/antiseptic hand cleaner was predicted by a higher level of education (Unadjusted/Crude odds ratio (COR) = 7.16, 95% CI 2.39–21.40, p = 0.000 and COR = 9.58, 95% Confidence Interval (CI) 3.28–27.92, p = 0.000, bachelors and masters, respectively), lengthier service (COR = 6.90, 95% CI 1.40–34.17, p = 0.015 and COR = 7.8, 95% CI 1.49–40.98, p = 0.015, 5–8 and >8 years, respectively), and presence of handwashing facility (COR = 4.48, 95% CI 1.34–14.95, p = 0.015). However, post-care handwashing was also associated with a higher level of education (COR = 13.36, 95% CI 1.54–115.63, p = 0.019, masters) and availability of soap (COR = 17.73, 95% CI 5.03–59.73, p = 0.000), as well as by male sex (COR = 3.14, 95% CI 1.01–9.79, p = 0.049). Implementation of an effective training program on hand hygiene combined with improved access to handwashing stations and adequate supply of soap or antiseptic hand cleaner is required to improve both pre-and post-care clinical encounter handwashing practices among CHCPs.

With rapid urbanization in recent years, the frequency of extreme rainfall events has increased in major cities around the world during the flood season, and the social and economic losses caused by heavy rainfall are becoming increasingly serious. The results show that (1) the overall duration of rainfall exhibits a downward trend, and the overall spatial performance gradually decreases from east to west. (2) The mountainous areas are prone to light and moderate rainfall events; the plains are more prone to rainfall events at levels above moderate rain, especially rainstorms and heavy rain events; the probability of light and moderate rainfall events in the suburbs is close to that of the urban areas, but the probability of rainfall events at levels above heavy rain is less than that of the urban areas; the probability of rainfall events of all levels in the outer suburbs is higher. (3) Increase in rainfall in urban areas compared to the southern suburbs is greater. (4) With increasing urbanization, the built environment in the mountainous areas and plains has continued to grow, and the original underlying surface conditions have changed.
New developments in the processing of metallic alloys for achieving exceptional superplastic properties
Authors: Wang C.T.
Published: June 2023

Abstract. The process of superplasticity has a long history dating back to the early experiments of Pearson conducted in the U.K. in 1934. Since that time, superplasticity has become of increasing importance because of the recognition that superplastic forming provides a simple procedure for the processing of complex and curved parts for use in a wide range of industrial applications. The fundamental requirement for superplastic flow is a small grain size typically smaller than ~10 µm. These fine grains were achieved traditionally through the use of appropriate thermo-mechanical processing which provided a procedure for developing microstructures having grain sizes of the order of a few micrometers. Over the last two decades the processing procedures have been further developed through the use of techniques based on the application of severe plastic deformation (SPD) where it is possible to achieve ultrafine-grained materials with grains sizes in the submicrometer or even the nanometer range. Early SPD experiments were conducted using the processes of equal-channel angular pressing or high-pressure torsion but more recently a new and improved technique was developed which is known as tube high-pressure shearing (t-HPS). Experiments show that t-HPS provides a capability of producing exceptional superplastic elongations with, for example, an elongation of ~2320% in a Bi-Sn alloy when tested at a strain rate of 10-4 s-1 at room temperature. This report examines these recent developments with an emphasis on the potential for improving the superplastic capabilities of metallic alloys.
Mechanical and microstructural analysis of Ti-6Al-4V material in a wide range of superplastic forming conditions
Authors: Sancho A.
Published: June 2023

Abstract. In order to accurately define the superplastic forming (SPF) conditions of Ti-6Al-4V material, an understanding of the stress-strain behaviour, the initial microstructure, and their evolution during superplastic deformation are required. Ti-6Al-4V material with microstructure beneficial for SPF was superplastically tested according to the ASTM E2448 standard considering a wide range of forming conditions in terms of temperatures (750°C – 830°C) and strain-rates (seven strain-rates ranging from 5∙10^(-5) s^(-1) to 〖5∙10〗^(-2) s^(-1)) – some of the tests of the 3x7 matrix are considered “extreme” conditions from an SPF point of view. The material showed improved superplastic behaviour, which was evident from the stress levels and strain-rate sensitivity values as estimated from the flow curves obtained for the different conditions. In comparison with other commercial alloys or results from similar analyses published in the last decades, low stress values and high strain-rate sensitivity (m) values were obtained despite the low temperatures and high strain-rates used in this analysis. The tests were interrupted when 0.5 true strain (65% engineering strain) was achieved followed by quenching, as this was the maximum local strain achieved when forming the component of interest. Samples did not show any sign of premature necking or failure, with the exception of the two most “extreme” cases. Particularly for the lower strain-rates (below 10^(-4) s^(-1)), some level of material hardening associated with a minimum grain growth was observed in the flow curves. In contrast, a noticeable material softening was observed for the higher strain-rate conditions (above 5∙10^(-3) s^(-1)), associated with the microstructural changes occurring due to dynamic recrystallization. These higher strain-rates led to formation of submicron-sized grains, which could have helped in the superplastic response of the material under these strain-rate conditions. Intermediate strain-rates (5∙10^(-4) s^(-1) and 10^(-3) s^(-1)) showed a different type of response in terms of microstructural behaviour (and flow curve outline) depending on the testing temperature. A negligible amount of cavitation was observed in the samples tested under extreme conditions.

Published: June 2023

Abstract. In this paper, the forming process research of the front opening and closing mechanism hatch for multiple units was carried out, and the industrial grade 5083 aluminum alloy was selected as the original material. The uniform rapid superplastic forming process combined with hot stamping and direct-reverse superplastic forming was used to form the hatch body skin, the cold stamping and argon arc welding process were used to produce the connection support, and the hatch integral part was obtained by argon arc welding finally, which solved the problem of poor environmental protection and high ratio of traditional FRP hatch and high precision forming of the large complex thin-walled structural part that cannot be achieved by the traditional forming process. After process research and development, finite element analysis, and forming tests, the aluminum alloy hatch with good forming quality was successfully manufactured. The ultimate thinning rate of the part was 23.8%, the overall wall thickness was evenly distributed, the deviation of shape was controlled within 1 mm, and the mechanical properties met the relevant technical requirements.
