Un modelo perfeccionado de la pipeta de Andreasen
Authors: Margarit Adrian
Published: November 2022

El autor que está llevando a cabo una investigación acerca de los procedimientos modernos para la medición de la finura de los cementos, ha introducido un perfeccionamiento en la conocida Pipeta de Andreasen, instrumento ya clásico, que utiliza el método de sedimentación para efectuar los análisis granulométricos de los cementos. Gracias a la adición de un aspirador adecuado, las extracciones periódicas que hay que hacer se logran con toda precisión y seguridad aparte de una mayor comodidad para el operador. Da también, a continuación una idea de la aplicación que en la investigación llevada a cabo en aquél Instituto se hace de este aparato para el estudio comparativo entre los procedimientos de determinación a base del Turbidímetro" de Wagner y del Permeabilimetro de Blaine, que se deben extender en un futuro próximo a los fluorómetros y a otros métodos aún más nuevos, destinados en principio a sustituir con ventaja a los anticuados métodos de determinación a base de tamices que aún so hallan en vigor en la mayoría de los países.

Nuevas técnicas para el estudio del fraguado de los aglomerantes hidráulicos
Authors: Calleja J.
Published: November 2022

En el presente trabajo se trata de establecer experimentalmente las diferencias entre los comentos aluminosos y los portland en cuanto a su comportamiento frente a una nueva técnica que ya fue descrita (1) (2), para determinar el tiempo de fraguado (principio, fin e intervalo), basada en las variaciones de resistencia eléctrica de pastas confeccionadas con dichos cementos.
Los resultados experimentales conducen a la conclusión de que esta técnica no puede ser aplicada al cemento aluminoso, al menos en la misma forma en que lo es para el portland, debido a que muy verosimilmente existo una superposición parcial de los procesos de fraguado y endurecimiento en el caso del cemento aluminoso.

Édito - L’autorité et le pouvoir éducatifs à l’épreuve des politiques d’éducation
Authors: Roelens Camille , Mierzejewski Stéphan
Published: November 2022

Ce dossier aborde la question de la recomposition des rapports de pouvoir et d’autorité au sein du système scolaire en interrogeant dans leur globalité les relations à l’œuvre entre les différents acteurs de l’institution scolaire chargés de définir, encadrer et mettre en œuvre les politiques publiques censées répondre aux défis du temps. En se centrant sur les personnels de direction, d’encadrement ou de formation, et en faisant valoir la multiréférentialité des sciences de l’éducation et de la formation, les textes de ce dossier se saisissent de cette question à la racine en envisageant les implications à l’échelle la plus globale et les incidences professionnelles les plus pratiques et quotidiennes. Saisies à partir de la situation de celles et ceux qui, dans le système éducatif, sont censés l’incarner au premier chef, les conditions et modalités concrètes de métamorphose de l’autorité institutionnelle révèlent alors combien l’exercice des responsabilités correspondantes est mis à l’épreuve par les politiques publiques contemporaines dites de responsabilisation et le lot d’incertitudes et d’injonctions paradoxales qu’elles charrient.
Rapports de force et crise de l’autorité dans le mouvement Freinet entre 1945 et 1968 : quand l’horizontalité questionne la verticalité
Authors: Riondet Xavier
Published: November 2022

Peut-on diriger et doit-on impulser une direction dans un mouvement pédagogique qui, lui-même, remet en question certaines formes d’autorité ? Pour répondre à cette interrogation, ce texte aborde la question des rapports de pouvoir et de la crise de l’autorité dans le cadre du développement du Mouvement Freinet entre 1945 à 1968. Cet article montre comment, structurellement, le contexte institutionnel de la pédagogie de cette époque rend nécessaire ce travail de direction et de coordination, alors que, conjoncturellement, le fait que les relations sociales entre adultes et entre adultes et enfants connaissent des mutations significatives vient remettre en question cette nécessité et la possibilité d’incarner une tradition.
La direction d’école primaire, une question de pouvoir ?
Authors: Roaux Cécile
Published: November 2022

Cet article propose d’examiner comment la transformation du « référentiel » éducatif fragilise la position des directeurs d’école en France et pose la question de leur pouvoir. Si les responsabilités de ces derniers se sont accrues, se rapprochant de celles des chefs d’établissement du second degré, l’école primaire reste marquée par une division du travail éducatif et un patriotisme de corps pour préserver l’autonomie des acteurs dans la classe. À partir d’une enquête par questionnaire évoquant la question du statut des directeurs d’école, sera étudiée la coupure idéologique entre enseignants et directeurs, qui a pour effet d’assigner ces derniers à un travail dévalorisé, les plaçant en marge du fonctionnement de l’école dont ils sont pourtant seuls responsables. Notre cadre d’analyse est celui de la sociologie des organisations et des systèmes.
Pression temporelle et situation de porte-à-faux. Regard socio-didactique sur les positionnements professionnels des conseillers pédagogiques de circonscription - « tuteurs terrain »
Authors: Mierzejewski Stéphan , Zaid Abdelkarim
Published: November 2022

Cet article aborde la problématique générale du dossier, en l’envisageant du double point de vue de la pression temporelle et des contradictions structurelles qui caractérisent l’évolution des missions de conseiller pédagogique de circonscription. Chargés du tutorat des fonctionnaires-stagiaires de l’enseignement primaire dans de nombreuses académies, les positionnements professionnels de cette catégorie spécifique d’acteurs expriment la profonde ambivalence des politiques de formation enseignantes françaises qui, sous couvert d’accompagnement des parcours, contribuent à asseoir des logiques de contrôle dont les effets formatifs peuvent être très éloignés des objectifs officiellement assumés. L’approche socio-didactique développée permet d’en examiner les incidences au plus près de l’activité d’accompagnement des conseillers pédagogiques de circonscription. Les auteurs s’appuient à cette fin sur huit entretiens exploratoires, ainsi que sur de nombreuses observations directes.
Conceptions intuitives des notions de justice et de liberté : résultats d'une étude au collège dans le cours d'enseignement moral et civique
Authors: Sander Emmanuel , Marcoux Géry , Wyss Anouchka , Naud Stéphanie , Scheibling-Sève Calliste , Gros Hippolyte , Gvozdic Katarina
Published: November 2022

Le développement de la pensée critique en tant que compétence transversale est devenu un enjeu éducatif dans de nombreux pays. Plus encore, il semble, aujourd’hui, crucial de préparer les élèves, en tant que membres déjà actifs de la société et citoyens de demain, à porter un regard critique, au sens d'avoir une opinion éclairée, sur les valeurs proposées par la société dans laquelle ils sont insérés. En France, il existe un programme d’enseignement moral et civique qui a pour ambition de servir cet ob-jectif. Cependant, il apparaît de plus en plus clairement que les conceptions intuitives peu-vent entraver la réflexion et les prises de décisions quant aux questions de société. Dans ce cadre, améliorer ses connaissances des conceptions existantes de notions essentielles en éducation citoyenne telles que la justice et la liberté devrait permettre d’aller au-delà de ces idées premières et de faire évoluer les perspectives, favorisant ainsi le développement de l’esprit critique. C’est l’objet de l’étude sur lequel porte cet article.
Perceptions of the HIV counselling and testing programme by patients in a rural regional hospital in South Africa
Authors: Orisakwe Emeka , Ochiogu Stella , Ocholla Peter
Published: November 2022

Background: Human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) have become a major public health challenge worldwide in the past few decades. The impact is felt in all sectors in South Africa, as in other parts of sub-Saharan Africa. Several health-related approaches have been adopted to facilitate an understanding of and reduction in the risk factors associated with HIV and AIDS. Following the demonstration of underperformance by the new voluntary counselling and testing (VCT) guidelines in South Africa, otherwise referred to as HIV counselling and testing (HCT), in providing practical suggestions on ways to optimally engage clients to ensure that testing for HIV is being performed, an evaluation to ascertain other patient-influencing factors on healthcare worker-initiated HCT was needed. Thus, the aim of this study was to describe patients’ perceptions of the benefits of and barriers to HCT, and their willingness to test.Method: One hundred and seventy-two patients referred for HCT were randomly selected over a three-month period. Data were collected by a research assistant using the modified standardised World Health Organization/ Health Global Access Project (HGAP) questionnaire.Results: The majority of the participants demonstrated a good perception of the benefits of and barriers to HCT, and most reported good self-efficacy with regard to protecting themselves against HIV infection and preventing the acquisition thereof. However, only 74% were confident enough to test for HIV, while 28% reported being reluctant to notify their partners of their status if they tested positive, and 38% reported fear of healthcare workers showing discrimination as a barrier to HCT.Conclusion: Despite excellent perceptions of the HCT programme, a significant association between participants’ perceptions of HCT and their willingness to test for HIV was not reported (p 0.05).
Pharmacotherapy during pregnancy, childbirth and lactation: points and principles to consider (a 2015 update)
Authors: Schellack G. , Schellack N. , Kriel M.
Published: November 2022

Pregnancy, childbirth and lactation pose unique challenges in terms of drug therapy. The pregnant mother and her unborn child are exceptionally vulnerable from a physiological, clinical and ethical standpoint. This warrants careful consideration with respect to a number of important aspects, which could firstly influence the decision to opt for drug therapy, and secondly, could influence the specific agent selected for each indication. The US Food and Drug Administration has introduced changes to the content and format of information presented in prescription drug labelling to assist healthcare providers when assessing benefit versus risk, and in the subsequent counselling of pregnant woman and nursing mothers who need to take medication. This change came into effect at the end of June 2015. This article provides an overview of these important aspects.
HIV in acute care: a review of the burden of HIV-associated presentations to an Emergency Department
Authors: Naicker B. , Maharaj R. C.
Published: November 2022

Objective: To determine the burden of human immunodeficiency virus (HIV) disease and co-infection on a district-level Emergency Department (ED) in KwaZulu-Natal. Methods: A retrospective chart review was conducted of the case notes of adult medical patients who presented to the ED over a three-month period. Patients presenting with HIV disease and its complications were identified. Patient demographics, disease presentation and severity, investigations and procedures undertaken, and disposition of patients in the HIV-positive cohort were assessed.Results: 428 of the 861 (49.7%) medical patients presenting to the ED were HIV positive. Some 37% of patients did not know their HIV status. In the HIV-positive cohort, the median age of presentation was 37 years, with almost equal male-to-female distribution. Of the patients seen, 57.5% were referred and 68% of patients presented after hours. In total, 80% of patients were triaged as yellow code. The predominant systems involved were the respiratory and central nervous systems, with pulmonary tuberculosis, community-acquired pneumonia and meningitis being the most common diagnoses. X-rays and laboratory testing were the most common investigations requested. Lumbar punctures, pleural paracentesis and pericardiocentesis were common emergency procedures performed. The majority (89.3%) of patients were admitted to the medical ward. Of the HIV-positive patients, 33% were on anti-retroviral therapy. ED mortality was 1.9%.Conclusion: In South Africa, very little is known about the ED’s ability to cope with the HIV epidemic. This study highlights the significant impact HIV places on the resources of an ED. Strengthening of the primary health care system with a more aggressive approach to HIV testing and ARV initiation may contribute positively to reducing the burden of HIV emergencies and co-morbidities presenting to the ED.MeSH: Human Immunodeficiency virus (HIV); Emergency Department, South Africa, opportunistic infections; HIV testing
Lung function decline is accelerated in South Africans with cystic fibrosis
Authors: Masekela R. , Olorunju S. , Green R. J. , Magidimisa N. T.
Published: November 2022

Background: Poor nutritional status has been shown to be associated with a significant decline in lung function in patients with cystic fibrosis. There are few data published on the lung function decline and the effects of nutritional status in cystic fibrosis (CF) in South Africa. Aim: To assess anthropometric parameters (weight, height, body mass index Z-score) in relation to lung function parameters in CF patients. Methodology: A retrospective chart review of clinical records of participants over the age of five years attending the CF clinic at Steve Biko Academic Hospital from 2005 to 2010. Results: Twenty files were reviewed for lung function, anthropometric measurements, gender and CF-causing mutations. For anthropometric measurements the average changes were –0.8, –0.5 and 2.0 for weight, BMI and height Z-scores, respectively. A decline in FEV1 of –25.3 (95% CI 39.4; –13.3) over the five-year period was noted, with an average decline of 5.3% per year. For FEF25-75, the average change was –22.4 (95% CI-34.6; –10.2) with a decline of 4.5% per year. Using multivariate analysis, the FEV1 was found to be significantly influenced by: age –3.96 (95% CI –7.4; –0.5); p = 0.03, weight 1.8 (95% CI –3.4; –0.9); p = 0.04, BMI Z-score 4.3 (95% CI 5.3; 23.3); p = 0.02 and gender (p = 0.02). The FEF25-75 was significantly influenced by BMI Z-score and gender. Conclusion: The average lung function decline per year for FEV1 was higher than that seen in developed countries. The decline in FEV1 was related to gender, age, weight and BMI. The decline in FEF25-75 was affected only by BMI Z-score and gender.
South Africa has joined a global initiative for Family Medicine advocacy
Authors: Von Pressentin Klaus , Hoedebecke Kyle , Pinho-Costa Luís
Published: November 2022

The international #1WordforFamilyMedicine initiative serves to explore the identity of family physicians and allows the international Family Medicine community to collaborate on advocating the discipline. South African family physicians provided 42 responses via a social media and online survey. Two “word cloud” images were created based on two icons recognised as being truly South African around the world – the national flag and former president Nelson Mandela. The #1WorldforFamilyMedicine initiative was promoted by the World Organization of Family Doctors across the globe to help celebrate World Family Doctor Day on 19 May 2015. To date, over 70 images have been created in 50 different countries on six continents. The images represent family physicians’ love for their profession and the community they serve. It is hoped that this initiative will help to inspire current and future Family Medicine and primary care providers.
Analgesia for acute pain
Authors: Van Rensburg R.
Published: November 2022

Acute pain is known to every person universally, and the management of pain is one of the biggest industries in the world today. There are many and varied options to achieve analgesia, but if not used for the correct indication, if not initiated effectively, or if the intervention causes unacceptable side-effects, it can lead to suboptimal pain relief and potentially dire outcomes. Knowledge of the pathways involved in pain perception, and how these pathways can be targeted with various modalities is required to obtain adequate analgesia. This article provides an overview of the available evidence-based therapeutic options for acute pain management.
Additional considerations for gastro-oesophageal reflux disease
Authors: Marais A.
Published: November 2022

Gastro-oesophageal reflux disease (GORD) is a common condition worldwide. It is characterised by numerous upper gastrointestinal tract symptoms, but patients mainly present with heartburn and regurgitation. Various causes have been linked to the pathophysiology of GORD. Some of them are well known, while others are less frequently implicated. Oesophageal inflammation is the result of the inadequately managed suppression of gastric acid caused by the retrograde flow from the stomach through the lower oesophageal sphincter, which may result in complications, including stricture formation, Barrett’s oesophagus, erosive oesophagitis and adenocarcinoma. The incidence per region and country varies significantly, and is dependent on the population demographics. GORD is responsible for an impaired general health score in affected individuals, and has a negative impact on economic productivity in society. Treatment may range from unscheduled self-medication to complicated laparoscopic surgery. This article describes some of the associated factors, revised definitions and the role of surgery in the management of GORD.

Dijital medyada etkileşimi ve katılımcı kültürü talep eden bir eğlence deneyimi yaratmak amacıyla kurgulanan mecralar-arası hikâye anlatımı transmedya anlatı olarak nitelendirilmektedir. Buna göre, hikâye mümkün olduğu kadar çok ve farklı medya platformunda anlatılmaktadır ve hikâyeye ait bilgilerin tümünü barındıran tek bir mecra yoktur. Kasıtlı olarak boşlukların bırakıldığı ve bu eksiklikleri tamamlamaya çalışan hayranların katılımı ile genişleyen transmedya hikâye evreninde, çevrimiçi ve çevrimdışı dünya veya kurgusal dünya ile gerçek dünya birbirinin içine geçmektedir. Bu çalışmada, Valorant adlı dijital oyun için hayranların ürettiği görsel ve yazılı içerikler, “yakınsama”, “katılımcı kültür” ve “kolektif zeka” kavramlarıyla ilişkili olarak ve transmedyanın yedi ilkesine göre durum çalışması metodolojisi kullanılarak analiz edilmektedir. Bulgulara göre yakınsama, kolektif zeka ve katılımcı kültür sayesinde ortaya konan hayran performansı, transmedyanın yayılabilirlik, derine inebilirlik, çeşitlendirilebilirlik, dünya inşa etme ve performans ilkeleri ile örtüşmektedir. Sonuç olarak, kolektif zeka ve katılımcı kültür, hayranların transmedya hikâye evrenine kültürel ve sanatsal içerik üretimleriyle katkıda bulunmasını sağlamaktadır.

Spatial planning performance indicators are related to sustainability. This approach combines quantitative and qualitative data to see the sustainability of regional spatial planning based on land and policies. This study aims to: (1) Analysis of the sustainable development index (IPB) and (2) Analysis of causal conditions of spatial planning performance assessment per regencies/municipalities based on IPB. The approach used is IPB, geographic information system, multi-value qualitative comparative analysis and literature study. The highest score of IPB is Bandung Municipality. The income per capita, education and welfare of the Municipality of Bandung are higher than in other regions. Considering the distribution of IPB scores and their constituent variables, subsequent analysis shows the need to differentiate between regencies and municipalities. Regional sustainability in this regency offers high compatibility between spatial planning policies and forest area status policies have extensive vegetation cover and small land-use diversity. Whereas in urban areas, it shows the opposite. This article can answer the sustainability of spatial planning policies and differentiate between regencies and municipalities—the use of mvQCA is a new approach to spatial planning evaluation.

The work is devoted to the assessment of the quality of drinking water selected from different types of water supply sources. The description of the problem of water pollution is given, the relevance of the research is substantiated. The sources of water sampling are indicated: centralized water supply system, underground water and water machines "Vodorobot". A brief description of the research methods used is given: titrimetric, potentiometric and inversion-voltammetric. The results of determining the following quality indicators are presented: hardness, oxidizability, content of nitrates and heavy metals – copper, lead, cadmium. Excess of permissible values of hardness, oxidizability, concentration of nitrates, lead and cadmium in a number of water samples was found. The possible reasons for the discrepancy of these indicators with the normative values are considered. An explanation is given for the excess of the values of the oxidability of samples of tap and ground water. The negative effects of high concentrations of nitrates and heavy metals on the human body are described. The features of heavy metals contributing to their migration in groundwater are listed. Special attention is paid to the causes of excessive lead content in water samples from water vending machines. It is established that the most common pollutants of the studied waters are organic compounds and lead ions. It was revealed that groundwater containing more than two ecotoxicants is more polluted. The authors note that there is currently no unambiguous answer to the question of a source containing water of satisfactory quality.

Relevance of the research topic is due to the global trend towards the development of clean energy, in particular, the utilization of carbon dioxide. Recently, electrocatalytic reduction of carbon dioxide has been considered as a promising way to utilize carbon resources and produce sustainable fuels. Due to the limited energy efficiency, uncontrolled selectivity, low stability, and uncertain mechanisms of electrocatalytic CO2 reduction, there are still many complex problems to be solved. In this regard, current research in the field of electroreduction of CO2 is relevant. Sustainable and cheap catalysts need to be developed for the electroreduction of carbon dioxide. This paper presents a review on sodium pectate with manganese as a catalyst in the carbon dioxide reduction reaction. It was experimentally proven that sodium pectate with manganese exhibits catalytic properties in carbon dioxide reduction as the overvoltage was reduced by 400 mV. The stability of this complex was also tested for some time, the current for 8 hours increases, which means that sodium pectate with manganese can maintain its catalytic activity in the carbon dioxide reduction reaction for a long time. In the future, this complex can replace other more expensive catalysts.

Atmospheric pollution with carbon dioxide is a serious environmental threat to the climate of our planet. We can find a way to solve it using the method of electrochemical reduction of CO2. This article presents the research results during which data were obtained on the formation of an iron-containing nanostructured surface of a glassy carbon electrode using the methods of electrochemical deposition and scanning electron microscopy, during which it was concluded that the longer the pectate complex with iron is deposited on the surface of the working electrode, the greater number of particles formed on its surface. The catalytic properties of the PG-NaFe complex in water were also tested using cyclic voltammetry when the solution is saturated with carbon dioxide. It was experimentally proved that the iron-containing complex PG-NaFe exhibits catalytic activity for the carbon dioxide reduction reaction in the course of this research. Method for the deposition of a sodium pectate complex with iron on the surface of a glassy carbon electrode without the use of expensive components was proposed based on the analyzed data.

This article describes the development and application of the approach of using a zeroing neural network (ZNN) to solve problems of optimizing carbon footprint emissions using the example of a system approach model.The described model is an integrated optimization problem based on a model previously developed by other authors and the method of zeroing neural networks. The optimization problem, which is described by the objective function representing the minimization of carbon emissions and restrictions, is complex. To solve this problem, an approach based on the use of zeroing neural networks was developed. The developed model is an improved version of the original model.In this work, we are developing an energyoriented production planning framework that takes into account economic indicators such as demand satisfaction and economies of scale. However, we do not calculate the associated production costs. In fact, it is necessary to find an important compromise between reducing emissions and production costs. Accordingly, energy-oriented production planning can be viewed as a multi-purpose optimization task in which decision makers try to optimize their decisions in terms of a set of goals, such as minimizing total emissions versus minimizing total costs.

Reduction of deficiency of macro- and microelements in foodstuffs (in particular, iodine and fluorine) of ecologically impoverished regions is possible in the development of new products. In this regard, dietary supplements have been introduced into the recipes of meat, fish, vegetable, cereal and curd dishes. The combination of the main raw materials and additives, the functional properties of the products have been studied, and the optimal organoleptic, structural-mechanical, and rheological properties have been established. Additive "Mobi-lux Universal", containing heme iron, organic calcium and iodine, enrich a wide group of products with minerals by creating protein-vegetable combined compositions. Recipes have been developed and technologies have been substantiated for “Morskie” fish cakes, “Pikantny” meat steak, “Raduzhny” fruit and curd dessert, fruit mousses, and “Appetitnaya” rice casserole with apples. The results of a study of the nutritional value of specialized food products based on meat, fish, vegetable, fruit, cereal products and cottage cheese, enriched with the Mobi-lux Universal complex functional additive, vegetable and fruit powders, are presented. More than 20 dishes have been developed and included in corrective diets for schoolchildren. It has been established that the maximum enrichment of meat and fish products is carried out with vitamins: Betacarotene, B6, B12, as well as macro- and microelements: iron, iodine, calcium, sodium, magnesium and fluorine. Protein-containing fish and meat dishes, due to the included additive, make up for 15% of the daily deficiency in these nutrients (iodine, calcium and iron). Dessert, mousse and casserole - to dishes-sources of bio-organic iodine, calcium and iron. This will fully balance the diet of students in the category of 7-11 years old. The developed dishes were tested in the production conditions of catering establishments of educational organizations.

A field survey of synchronized fireflies (Pteroptyx tener Olivier) was conducted in Kuala Sepetang, Perak. It involved sampling efforts for six months, from November 2021 to April 2022. A total of 10 sampling stations were selected along 5.63 km from the upstream to the downstream of the river. A sweep net was used for sampling at each station, and the net was swept for two minutes. Such sampling was replicated twice at each station. At the same time, collecting vegetation samples was done by taking the leaves, flowers, fruits, tree trunks, and roots. For species identification, collected specimens were taken to the Laboratory of the School of Biological Sciences, Universiti Sains Malaysia (USM). From this survey, a total of 111,622 individuals were recorded. This species has been observed on Rhizophora mucronata, Rhizophora apiculata, and Sonneratia caseolaris. The distribution and abundance of fireflies in the sampling area were undocumented prior to this study. This study is being conducted to understand Pteroptys tener’s distribution in Malaysia better and to add knowledge about the undocumented area of Kuala Sepetang. By adding an undocumented location for this species, this study can contribute to and expand the knowledge of the distribution and occurrence of fireflies in Malaysia, particularly in Perak.
The Influence of Fe on Grain Refinement of Recycled A 356 Alloy Initially Refined by Al-5Ti-1B Master Alloy
Authors: Chowwanonthapunya Thee , Peeratatsuwan Chaiyawat
Published: November 2022

This research investigated the effect of Fe on the grain refinement of the recycled A 356 alloy refined by Al-5Ti-1B master alloy using macrostructure examination and chemical composition analysis. Results showed that as recycling number increased, the grain refining performance of Al-5Ti-1B master alloy decreased, particularly in the subsequence recycling process. The decreased concentration of titanium and boron were responsible for the degraded grain refining effect in the recycled A356 alloy. Appropriate concentration of the residual iron in recycled A356 provided the grain refining effect which can compensate the degraded grain refining performance of Al-5Ti-1B master alloy. It is suggested that adding the additional Al-5Ti-1B grain refiner and an intentionally added iron of 0.3 wt. % should be a practical alternative to maintain the grain refining efficiency of recycled A356 alloy.

HIGHLIGHTS

Significant concern of the recycling process of A356 alloy is the degradation of the grain refining performance of Al-5Ti-1B grain refiner

The role of Fe on the grain refinement of Al-5Ti-1B grain refiner in the recycled A356 alloy is doubtful

The concentration reduction of titanium and boron was responsible for the degradation of the grain refining efficiency

Appropriate concentration of the residual Fe in recycled A356 alloy provides the grain refining effect

Adding the additional Al-5Ti-1B grain refiner and an intentionally added Fe of 0.3 % wt is suggested to be a practical alternative to maintain the grain refining efficiency of recycled A356 alloy
