Les effluents industriels issus des activités textiles présentent une grande charge polluante difficilement biodégradable et qui a des impacts non négligeables sur l’environnement et l’Homme. Leur décontamination par les procédés conventionnels biologiques ou physiques est souvent inefficace et nécessite par conséquent le recours à des procédés d’oxydation avancée dont l’électrocoagulation. Dans le présent travail, nous avons étudié l’élimination par électrocoagulation du bleu de méthylène, modèle de colorant synthétique textile, en utilisant des électrodes de fer et d’aluminium. L’étude des paramètres pouvant influencer l’élimination par électrocoagulation du bleu de méthylène tels que le pH, la durée de l’électrolyse, la densité de courant et la nature de l’anode a montré que les meilleurs traitements sont obtenus avec un effluent de pH égal à 7 pendant 4 heures d’électrolyse à une densité de courant de 3,75 A/cm2 en utilisant l’électrode de fer. Dans ces conditions, le pourcentage d’élimination du bleu de méthylène dans les eaux atteint 80,1%. Des électrodes en fer seraient donc plus intéressantes pour l’élimination du bleu de méthylène, comparativement à des électrodes en aluminium.Mots clés : Electrocoagulation, fer, aluminium, effluents industriels, bleu de méthylène.

English Title: Study of operator parameters in electrocoagulation for the treatment of a synthetic textile effluent: example of methylene blueIndustrial effluents from textile activities have a large polluting load that is difficult to biodegrade and which has significant impacts on the environment and on humans. Their decontamination by conventional biological or physical processes is often ineffective and therefore requires the use of advanced oxidation processes including electrocoagulation. In the present work, we investigated the electrocoagulation removal of methylene blue, a synthetic textile dye model, using iron and aluminum electrodes. The study of the parameters of EC which can influence the elimination of methylene blue in wastewater, such as the pH, the duration of the electrolysis, the current density and the nature of the anode showed that the best treatment are obtained with a pH effluent equal to 7, for 4 hours of electrolysis with an iron electrode at a current density of 3.75 A / cm2. Under these conditions, the percentage of elimination of methylene blue in water reaches 80.1%. Iron electrodes would therefore be more advantageous for the removal of methylene blue, compared to aluminum electrodes.Keywords: Electrocoagulation, iron, aluminum, industrial effluents, methylene blue.

A study was carried out with the objective of evaluating the microbiological and physicochemical quality of surface water in the Nkolafamba subdivision, Center Region of Cameroon. Five sampling points were selected based on several criteria. The bacteria isolated were Mesophilic Aerobic Heterotrophic Bacteria (BHAM), bacteria that were witnesses to faecal contamination and Pseudomonas. Some abiotic parameters were measured using the usual techniques. The results show that some physicochemical parameters such as temperature was almost constant around 25 °C during the study period. There is also a pH which tended towards neutrality pH de (7,04 ± 1,03 U.C). However, it was noted that the stations are quite oxygenated (63,96%). Bacteriological analyzes revealed that an average value of 5.17 units (logUFC / 100mL) was recorded for BHAM. Overall, the abundances of total coliforms averaged 4.18 units (logUFC / 100mL). The waters of Nkolafamba also harbor a pathogenic microflora, with bacteria such as P. aeruginosa P. pasteurella, the abundance of which can sometimes reach 5,462 units (log CFU / 100mL). These germs can be the cause of eye infections or septicemia on users of these waters. These waters have a high bacterial load, and the microbiological pollution observed is predominantly animal. Some abiotic parameters such as pH, electrical conductivity, Suspended Solid (SS), nitrates and turbidity have influenced the distribution of these germs. The degradation of the quality of these waters is favoured by their proximity to sources of pollution, the runoff of contaminated water in the stations. These waters, without any treatment, are not recommended for human consumption according to the standards of the World Health Organization.Keywords: Abiotic variables, faecal coliforms, faecal streptococci, pathogenic bacteria, rivers.

Published: June 2021

The switched reluctance motor (SRM) is among the special purpose electric machine family. It is simple in construction and avoids use of magnet so it is cheap to manufacture. The magnetic characteristics and simulation of three phase 12/8 switched reluctance motor (SRM) for enhanced starting torque is presented. The motor was analyzed using finite element technique (FET) and it was improved by focusing on the impact of important geometrical parameters on torque and efficiency. From the simulated results, the motor attained maximum efficiency of 91.7% at a speed of 1648.6 rpm and recorded a maximum torque of 321.1 Nm at a speed of 34.4 rpm. The magnetic flux lines and densities were also recorded. The maximum and minimum magnetic flux lines of the motor as observed were 1.2x10-3 Wb/m and -8.5x10-4 Wb/m respectively while the respective values of the maximum and minimum magnetic flux density of the motor were 3.8x10-1 T and 2.11x10-9 T. The results show that most of the field energy is confined within the motor and also concentrated in the air gap region of the motor. Dynamic analysis of the motor was performed for 0.02 s at a damping coefficient of 0.71 μNms/rad. The results showed that the motor has lower torque ripple. The preference to use this type of motor where high speed operation and better starting torque are needed has been highlighted in this study.

A pergunta que orienta toda nossa reflexão é por que não fizemos antes, nem ainda, essa ponte direta com Freire? Deixamos para o leitor inferir a(s) resposta(s) a partir da leitura do mundo e da palavra, conforme nos ensina Paulo Freire.
Against the factory school of modern times: the need of a paradigmatic rupture
Authors: Sousa Jesus Maria 
Published: June 2021

Despite the accelerating change at all levels of life, demanding a plethora of new intelligent systems, formal education continues to resemble a box, created during Industrial Revolution and only modestly changed since. The technicist curriculum and the public school remain a modernist project, boxing in students and constraining their imaginations.
It is not worth investing in intelligent technologies if education is not taken into account, creating new flexibilities for people’s behaviours and attitudes. A paradigm shift in the area of education and teacher education is a must.
The aim of this presentation is to share my concern about the inadequacy of the “black-and-white” mental organisation caused by the knowledge boundaries of various disciplines in hierarchical order, characteristic of the modernist curriculum implemented at schools, and the real need for a global and interdisciplinary methodological approach focused on the greatest problems of humanity.
On reflection: The role, mode and medium of the reflective component in practice as research
Authors: Green Michael Cawood , Williams Tony 
Published: June 2021

A key criterion in the recognition of practice as research is the inclusion of some form of critical self-reflection as a component of the creative project. This requirement that some form of complementary/supplementary discourse is necessary to establish the research status of creative practice is currently the subject of scrutiny and contestation across a number of disciplines. Noting how much work has been done in this area within the doctoral degree in Creative Writing in Australia, this paper explores some of the problematic areas in the formal recognition of practice as research within the UK’s research structures and processes. It argues that the scholarly rubric expected of the reflective component is not always the most appropriate medium through which creative work may be recognised as research. It considers tensions implicit in the dual role of supplementary discourses: that of documenting practice for institutional purposes and that of articulating and generating new knowledge about practice. The disciplinary placing of Creative Writing in the UK context also complicates its relation to other forms of practice as research. This paper argues that the recognition of a wider range of modes and media for supplementary discourses would allow the generation of new and different knowledge about creative practice, and make that knowledge differently available to researchers.

Bringing a new life to the world is a wonder to every mother. Experience faced by pregnant mothers vary from one pregnancy to another pregnancy. There is a vast amount of information available on the Internet and printed materials. Yet, this knowledge is too complex or lengthy and very few applications provide customized information to pregnant mothers. In a time where smart phones have become a necessity in our life, a mobile app is one of the easiest ways to obtain prenatal information. Hence, we have developed a mobile application to help pregnant mothers. This application includes an artificial intelligence (AI) based chatbot. AI chat bot communicates and guides the mother in a way that creates the illusion as if they are talking to their unborn child. The Spiral Model was used as the development methodology and the application was developed in an environment of continuous integration and deployment with GIT personal repository. This application was implemented using React Native and the Node.js. Chat bot was created with Dialogflow agent and integrated with the firebase through the Google cloud functions. Some existing applications were studied to identify the features and limitations of current pregnancy care mobile applications. This solution is realistic and successful and it has an upgradable model of growth. The rapid development of the Internet and mobile devices in the world has changed people's lifestyles. This mobile app will be helpful for pregnant mothers living in rural as well as in metropolitan areas alike and can enhance education and health.

Erste Hilfe für Originale im Notfall

Published: June 2021

Vielen ist noch der Brand in der Anna-Amalia-Bibliothek Weimar oder der Einsturz des Stadtarchivs Köln in Erinnerung. Unvorhergesehene Wassereinbrüche, Feuer oder sogar ganze Gebäudeeinstürze können wertvolle Bestände von Kultureinrichtungen beschädigen und im schlimmsten Fall sogar vernichten. Viele Objekte des Kölner Archivs sind bis auf Briefmarkengröße zerfetzt worden, geborgene Bände der Anna-Amalia Bibliothek derart verkohlt und verblockt, dass an ein Blättern nicht mehr zu denken ist.
Solche Katastrophen lassen sich nicht vorhersagen und kommen immer unangekündigt – und sie zeigen eindrücklich, wie notwendig es ist, sich auf Notfälle vorzubereiten und zu wappnen, um ein schnelles Handeln zu ermöglichen.

Segurança e a qualidade de vida encontram-se entre os maiores problemas da agricultura contemporânea. O uso de EPI ainda representa a principal estratégia para atenuar os riscos aos quais os trabalhadores agrícolas estão expostos. Entretanto, os EPI raramente são avaliados quanto a sua eficiência ergonômica ou aceitação de conforto por parte dos usuários. O objetivo desta pesquisa foi delinear atributos e especificações técnicas para conceber um conjunto de EPI que atendesse simultaneamente aos requisitos de segurança, conforto e usabilidade no plantio do abacaxi. A associação parcial dos métodos AET e QFDse mostrou bastante adequada para o desenvolvimento de artefatos de proteção.

The essence of the concept "creative thinking" is considered, and its working definition is formulated. Special attention is given to the identification of pedagogical foundations of future teachers' creative thinking development, which accounting will promote the increase of the efficiency of the considered process. Future teachers' creative thinking development is advantageously realized in the course of students’ vocational training, during which it is necessary to rely not only on mental development regularities knowledge (theoretical thinking, creative thinking peculiarities, sustained attention, imagination, and integration of memory) and students' individual characteristics (maturity of motivation to creative activities, the maturity of speech, volitional powers) but also on the competently organized didactic process (training to work with the concepts and their use, application of the system of creative tasks, developing the ability to overcome intellectual difficulties).
Results of students’ activity studying on the basis of creative tasks have shown that creative thinking skills development depends on the students' thinking orientation in the processing of the received educational information; Also, creative thinking skills development depends on students' subjective attitude towards tasks, that is going to be helpful them during the educational process.
This study aims to examine the essence of the concept of "creative thinking" and identify pedagogical foundations for its development in future teachers.
The following methods of scientific and pedagogical research are used to achieve the objectives: the methods of theoretical research: the analysis of psychological and educational literature; methods of empirical research: students' activity products' studying, observation, conversation, pedagogical experiment.

Published: June 2021

Background: Malignant melanomas of the oral cavity are rare tumours. The diagnosis of mucosal melanoma can be difficult especially when it presents itself in its amelanotic form.
Methodology: An electronic search was carried out on Pubmed and Medline database to find studies addressing this question published between Jan 2001 and April 2020. Multiple studies are done to determine the staining and positivity of the above mentioned three markers were found. A total of 4 studies were finally selected for this review which tried to determine the efficiency of these three markers in the diagnosis of oral mucosal melanomas.
Results: The patient’s data that stained positive S100, HMB45 and Melan A from 4 studies were selected.
Conclusion: S100 continues to remain the most sensitive marker for melanoma with its promising ability in diagnosing the desmoplastic variant. The lack of specificity is still a drawback of S100.
