The complete mitochondrial genome of the Arctic fairy shrimp Branchinecta paludosa (Müller, 1788) (Anostraca, Branchinectidae) from Sirius Passet, North Greenland
Authors: Kihm Ji-Hoon , Jo Euna , Park Tae-Yoon , Kim Bo-Mi
Published: October 2022

Here we report the complete mitochondrial genome of the Arctic fairy shrimp, Branchinecta paludosa (Müller, 1788) (Anostraca, Branchinectidae), which was collected in the High Arctic of North Greenland. A complete 16,059 bp mitochondrion of B. paludosa was sequenced and assembled with the Illumina next generation sequencing platform. The B. paludosa mitogenome contains 13 PCGs, 22 tRNAs and 2 rRNA genes that are commonly observed in most metazoans and shows the conserved gene arrangement pattern of Anostraca. Our results of the phylogenomic analysis are consistent with the previous phylogenetic relationship, based on nuclear 18S ribosomal DNA. The B. paludosa mitogenome will be useful for understanding the geographical distribution and phylogenetic relationship of anostracans.
FPGA Implementation of Fast Binary Multiplication Based on Customized Basic Cells
Authors: Al-Nounou Abd Al-Rahman , Al-Khaleel Osama , Obeidat Fadi , Al-Khaleel Mohammad
Published: October 2022

Multiplication is considered one of the most time-consuming and a key operation in wide variety of embedded applications. Speeding up this operation has a significant impact on the overall performance of these applications. A vast number of multiplication approaches are found in the literature where the goal is always to achieve a higher performance. One of these approaches relies on using smaller multiplier blocks which are built based on direct Boolean algebra equations to build large multipliers. In this work, we present a methodology for designing binary multipliers where different sizes customized partial products generation (CPPG) cells are designed and used as smaller building blocks. The sizes of the designed CPPG cells are 2×2, 3×3, 4×4, 5×5, and 6×6. We use these cells to build 8×8, 16×16, 32×32, 64×64, and 128×128 binary multipliers. All of the CPPG cells and the binary multipliers are described using the VHDL language, tested, and implemented using XILINX ISE 14.6 tools targeting different FPGA families. The implementation results show that the best performance is achieved when cell 3×3 is used and Virtex-7 FPGA is targeted. The binary multipliers that are designed using the proposed CPPG cells achieve better performance when compared with the binary multipliers presented in the literature. As an application that utilizes the proposed multiplier, a Multiply-Accumulate (MAC) unit is designed and implemented in Spartan-3E. The implementation results of the MAC unit demonstrate the effectiveness of the proposed multiplier.

Authors: FalvoJr Venilton , Marcolino Anderson da Silva , Duarte Filho Nemésio Freitas , OliveiraJr Edson , Barbosa Ellen Francine
Published: October 2022

The popularity of mobile devices in all social classes has motivated the development of mobile learning (m-learning) applications. The existing applications, even having many benefits and facilities in relation to the teaching-learning process, still presents problems and challenges, es- pecially regarding the development, reuse and architectural standardization. Particularly, there is a growing adoption of the Software Product Line (SPL) concept, in view of research that investigates these gaps. This paradigm enables organizations to explore the similarities and variabilities of their products, increasing the reuse of artifacts and, consequently, reducing costs and development time. In this context, we discuss how systematic reuse can improve the development of solutions in the m-learning domain. Therefore, this work presents the design, development and experimental evaluation of M-SPLearning, an SPL created to enable the systematic production of m-learning applications. Specifically, the conception of M-SPLearning covers from the initial study for an effective domain analysis to the implementation and evaluation of its functional version. In this regard, the products have been experimentally evaluated by industry software developers, pro- viding statistical evidence that the use of our SPL can speed up the time-to-market of m-learning applications, in addition to reducing their respective number of faults.
L’éducation à l’entrepreneuriat des adultes en reprise d’études : un défi pour l’enseignant
Authors: Makaya Christian
Published: October 2022

L’impact de l’hétérogénéité des profils d’apprenants sur la gestion et l’animation des dispositifs d’éducation à l’entrepreneuriat a été peu abordé dans la littérature. Les enseignants semblent peu préparés à cet enjeu, d’autant plus si leurs apprenants sont des adultes en reprise d’études. À travers une étude qualitative autour de deux formations à la création et la reprise d’entreprises accueillant une diversité d’apprenants adultes, nous cherchons à identifier les postures, stratégies et outils mis en œuvre par des enseignants en entrepreneuriat pour s’adapter à ce défi. Cette étude nous conduit à caractériser l’influence multidimensionnelle de la diversité des apprenants sur l’animation d’un cours d’entrepreneuriat ainsi qu’à identifier des actions permettant à l’enseignant de mieux s’adapter à ce défi. Nos travaux visent à permettre aux enseignants en entrepreneuriat de se préparer à une meilleure gestion des classes hétérogènes et contribuent ainsi à apporter une réponse pratique à l’un des effets de la massification de l’éducation entrepreneuriale.
Le Titre IX : s’appuyer sur le droit anti-discrimination pour lutter contre les violences sexuelles en milieu universitaire aux États-Unis
Authors: Mniai Soukayna
Published: October 2022

Cet article met en lumière comment le Titre IX de la loi sur l’enseignement supérieur de 1972, qui interdit toute discrimination fondée sur le sexe dans le domaine éducatif, a servi de point d’appui aux luttes contemporaines contre les violences sexuelles aux États-Unis. Le grand intérêt du Titre IX a été de créer des recours autres que la justice pénale pour les personnes victimes de violences sexuelles dans le cadre de leurs études. Mais il rencontre des limites dans sa mise en œuvre institutionnelle. Soukayna Mniai conclut sur la nécessité de mettre l’accent sur ses aspects préventifs plutôt que punitifs.

Published: October 2022

Dans le sillage de la mort de George Floyd et des manifestations antiracistes historiques qu’elle a suscitées aux États-Unis et à travers le monde, s’est diffusé le mot d’ordre d’abolition de la police. À quoi renvoie concrètement cette revendication ? Comment comprendre l’ampleur, la radicalité et le surgissement soudain de ces mobilisations états-uniennes et des idées apparemment nouvelles qu’elles charrient ? À partir de la recension de l’ouvrage Abolir la police , du collectif Matsuda, Shaïn Morisse revient sur l’actualité de ces enjeux de part et d’autre de l’Atlantique.
Comprendre la plasticité des dynamiques migratoires vers les États-Unis : entre pratiques territoriales et verticalisation des frontières
Authors: Salord Michelle
Published: October 2022

Les mobilisations et contre-mobilisations sociales aux États-Unis ne peuvent être pensées sans les migrations – à la fois économiques, politiques et culturelles – qui les suscitent ou les nourrissent. Dans cet article, l’anthropologue Michelle Salord propose de prendre du recul pour saisir à la fois l’ancienneté des flux migratoires reliant la Mésoamérique aux États-Unis ainsi que leurs transformations contemporaines, marquées notamment par la verticalisation des frontières et le renforcement des dispositifs sécuritaires qui les entourent.
Les quatre leviers de la redistribution
Authors: Guillaud Elvire , Zemmour Michaël
Published: October 2022

Nous étudions la redistribution monétaire en décomposant analytiquement quatre leviers : taux d’imposition, progressivité de l’impôt, taux de transferts sociaux, degré de ciblage des transferts. L’analyse porte sur 22 pays de l’OCDE, pour un ensemble de 67 observations, étalées dans le temps de 1999 à 2013. Nous nous appuyons sur les micro-données du Luxembourg Income Study sur le revenu des ménages, que nous complétons par l’imputation de données fiscales non observées. Notre analyse montre que la fiscalité produit un effet redistributif supérieur à celui des transferts en espèces (hors pensions de retraite) dans la plupart des pays. L’effet plus ou moins redistributif des transferts sociaux dépend davantage de leur niveau moyen que d’une différence de ciblage. En revanche c’est à la fois le taux d’imposition et la progressivité qui expliquent l’effet redistributif du système fiscal. Enfin, on observe une incompatibilité entre forte progressivité et haut niveau de prélèvements obligatoires.
Chronique de jurisprudence de la Cour africaine des droits de l’homme et des peuples (2021)
Authors: Burgorgue-Larsen Laurence , Sognigbe-Sangbana Muriel
Published: October 2022

La jurisprudence de la Cour africaine est marquée par une confirmation des nombreux standards posés tant dans le champ procédural que substantiel, les contentieux systémiques concernant le Bénin et la Tanzanie étant une des explications de cet état de fait. La Cour aurait pu aborder de nouvelles questions, notamment en matière de droits économiques et sociaux, dans des affaires portées notamment contre le Mali ; toutefois, sa jurisprudence restrictive ne lui permit pas de le faire. Sur le front consultatif, on relèvera la présence de deux avis, l’un seulement ayant été déclaré recevable, démontrant l’importance des contours restrictifs de la compétence personnelle de la Cour.
Le regard de la Cour européenne des droits de l’homme sur le formalisme excessif de la Cour de cassation de Belgique
Authors: Berbuto Sandra
Published: October 2022

Dans l’affaire qui donne lieu à l’arrêt commenté, la Cour européenne a, dans un premier temps, rayé de son rôle des requêtes introduites par des justiciables belges qui invoquaient une atteinte au droit à un tribunal en raison du formalisme excessif de la Cour de cassation. En effet, le gouvernement belge avait, par le biais d’une déclaration unilatérale, reconnu une violation de l’article 6 de la Convention, ce qui a entraîné cette radiation. Cependant, la Cour de cassation, saisie ensuite d’une demande de réouverture de la procédure, a estimé ne pas être liée par cette déclaration et a refusé d’y réserver suite. Les justiciables ont porté à nouveau leurs doléances devant la Cour européenne qui a, par l’arrêt du 21 septembre 2021, constaté que le droit d’accès à un tribunal n’avait pas été garanti.
Salduz n’a (toujours) pas dit son dernier mot : quelques nouveaux enseignements de la Cour européenne quant au droit à l’assistance d’un avocat lors de l’enquête pénale
Authors: Beernaert Marie-Aude
Published: October 2022

Au printemps 2022, la Cour européenne des droits de l’homme a prononcé trois arrêts qui méritent de retenir l’attention s’agissant du droit à l’assistance d’un avocat lors de l’enquête pénale. S’ils s’inscrivent tous les trois dans la droite ligne de la jurisprudence désormais bien établie de la Cour, ils ouvrent aussi un certain nombre de perspectives nouvelles en la matière.

Authors: Khammahawong Konrawut , Chaipunya Parin , Kumam Poom
Published: October 2022

An inertial Mann algorithm will be presented in this article with the purpose of approximating a fixed point of a nonexpansive mapping on a Hadamard manifold. Any sequence that is generated by using the proposed approach, under suitable assumptions, converges to fixed points of nonexpansive mappings. The proposed method is also dedicated to solving inclusion and equilibrium problems. Lastly, we give a number of computational experiments that show how well the inertial Mann algorithm works and how it compares to other methods.
Mathematical analysis of a COVID-19 model with different types of quarantine and isolation
Authors: Al-Yahyai Maryam , Al-Musalhi Fatma , Elmojtaba Ibrahim , Al-Salti Nasser
Published: October 2022

A COVID-19 deterministic compartmental mathematical model with different types of quarantine and isolation is proposed to investigate their role in the disease transmission dynamics. The quarantine compartment is subdivided into short and long quarantine classes, and the isolation compartment is subdivided into tested and non-tested home-isolated individuals and institutionally isolated individuals. The proposed model has been fully analyzed. The analysis includes the positivity and boundedness of solutions, calculation of the control reproduction number and its relation to all transmission routes, existence and stability analysis of disease-free and endemic equilibrium points and bifurcation analysis. The model parameters have been estimated using a dataset for Oman. Using the fitted parameters, the estimated values of the control reproduction number and the contribution of all transmission routes to the reproduction number have been calculated. Sensitivity analysis of the control reproduction number to model parameters has also been performed. Finally, numerical simulations to demonstrate the effect of some model parameters related to the different types of quarantine and isolation on the disease transmission dynamics have been carried out, and the results have been demonstrated graphically.
Product outsourcing policy for a sustainable flexible manufacturing system with reworking and green investment
Authors: Bachar Raj Kumar , Bhuniya Shaktipada , Ghosh Santanu Kumar , AlArjani Ali , Attia Elawady , Uddin Md. Sharif , Sarkar Biswajit
Published: October 2022

Production of defective products is a very general phenomenon. But backorder and shortages occur due to this defective product, and it hampers the manufacturer's reputation along with customer satisfaction. That is why, these outsourced products supply, a portion of required products for in-line production. This study develops a flexible production model that reworks repairable defective products and outsources products to prevent backlogging. A percentage of total in-line production is defective products, which is random, and those defective products are repairable. A green investment helps the reworking process, which has a direct impact on the market demand for products. A classical optimization solves the profit maximization model, and a numerical method proves the global optimal solutions. Sensitivity analysis, managerial insights, and discussions provide the highlights and decision-making strategies for the applicability of this model.
Threshold behaviour of a stochastic SIRS $ \mathrm {L\acute{e}vy} $ jump model with saturated incidence and vaccination
Authors: Zhu Yu , Wang Liang , Qiu Zhipeng
Published: October 2022

A stochastic SIRS system with $ \mathrm {L\acute{e}vy} $ process is formulated in this paper, and the model incorporates the saturated incidence and vaccination strategies. Due to the introduction of $ \mathrm {L\acute{e}vy} $ jump, the jump stochastic integral process is a discontinuous martingale. Then the Kunita's inequality is used to estimate the asymptotic pathwise of the solution for the proposed model, instead of Burkholder-Davis-Gundy inequality which is suitable for continuous martingales. The basic reproduction number $ R_{0}^{s} $ of the system is also derived, and the sufficient conditions are provided for the persistence and extinction of SIRS disease. In addition, the numerical simulations are carried out to illustrate the theoretical results. Theoretical and numerical results both show that $ \mathrm {L\acute{e}vy} $ process can suppress the outbreak of the disease.

Authors: Petrov Pavel , Kuyumdzhiev Ivan , Malkawi Rami , Dimitrov Georgi , Bychkov Oleksii
Published: October 2022

When delivering digitalization of educational services, a specific administration plan should be established, designed for maximum access, quick recovery from failure, and lowering the length of time it is unavailable, all while guaranteeing good security performance. It should include responsibilities such as providing dedicated servers for digitizing educational services, increasing security by using encryption and security-compliant network protocols, and database administration. To speed up the digitization of educational services, it is recommended that all databases be placed on a single server that will serve as the publisher, and that separate databases be distributed to three different servers that will act as the subscribers.

Published: October 2022

Nowadays the threat of cyber-attacks is increasing as more organizations undergo digital transformation. Therefore, organizations need to take proactive measures to mitigate the cyber threat to avoid further loss to their business. To mitigate cyber risk effectively, organizations need to employ competent people in the IT security team to implement effective security controls. But there is a shortage of cyber security talent or professionals in the job market and to produce talents in the cyber security field requires extensive effort in education and training. A good cyber security education program should have to date curriculum and provide practical experience. To achieve this, the program must be supported by a cyber security lab equipped with various software, equipment, and tools used by a real professional in the industry. Therefore, this paper proposed a model of a cyber security lab equipped with honeypot and SIEM systems to enhance the quality of cyber security education. The cyber security lab based on the model was deployed at Universiti Teknologi MARA (UiTM) and used for teaching and learning activities. The honeypot will provide student experience analyzing the behaviour of hackers while the SIEM system will aggregate the logs data of the Campus Network Firewall in real-time. To evaluate the effectiveness of the proposed lab model, a functional test and a survey was conducted. The survey result shows that majority of the respondent agreed that the cyber security lab improve their teaching and learning experience while taking the cyber security subject.

Conclusions can provide important references to expand the research scope and content of TPACK, promote the professional development of civil engineering teachers in universities, and help them enrich information knowledge structure.
Circulation et contrôle de la parole dans les couvents dominicains (XIIIe-XIVe siècle)
Authors: Polo de Beaulieu Marie Anne
Published: October 2022

Pour comprendre la genèse et l’application d’un usage idéal dominicain des pratiques langagières, il importe de le replacer dans un contexte paradoxal entre vie active (promouvant une parole exemplaire et efficace) et vie contemplative (valorisant le silence). Héritiers de la tradition monastique de la garde de la langue et acteurs d’un essor sans précédent de la prédication au peuple, les Dominicains doivent devenir les « nouveaux maîtres de la parole », tout en se gardant des péchés de langue, particulièrement étudiés au xiiie siècle. Ils se donnent comme modèles d’éloquence saint Dominique mais aussi les premiers frères de leur Ordre, tout en promulguant une règlementation stricte de la parole à l’intérieur de la communauté qui circule de manière plus verticale qu’horizontale. On verra que des paroles provenant de l’extérieur de la clôture pénètrent dans les couvents, via la mise à l’écrit de sources orales dans les recueils d’exempla et via des échanges de lettres chez certaines moniales dominicaines
Les biches comme mères dans l’exégèse médiévale
Authors: Girault Clémentine
Published: October 2022

Alors que l’on trouvait dix biches dans le texte hébreu, la traduction de l’Ancien Testament en latin par saint Jérôme n’en conserve que trois : celles qui étaient associées à un faon (Jb. 39, 1 ; Pr. 5, 19 et Jr. 14, 5). Les théologiens, suivant le commentaire de Bède, trouvent dans le verset des Proverbes un support fécond pour des analogies mariales, ecclésiales et conjugales, faisant de la biche un modèle de maternité. Celui-ci culmine au xiie siècle sous l’influence du culte de la Vierge. Parallèlement, une autre tradition exégétique inspirée de Grégoire le Grand voit dans la douleur des biches parturientes de Job et Jérémie un parallèle avec celle des prédicateurs et apôtres. Cette association a priori surprenante avec des personnages masculins éclaire en fait la construction fluide du genre au Moyen Âge. Enfin, l’évolution du motif de l’analogie biche-Christ, dans les textes comme dans les images, permet d’appréhender la façon dont les biches perdent progressivement leur ambivalence et se féminisent à la fin de la période.
Le serin amoureux
Authors: Amborg Jens
Published: October 2022

Cet article interroge la co-construction des concepts de race, de sexe et de reproduction dans l’histoire naturelle et l’élevage des animaux au xviiie siècle. L’analyse porte sur l’article « Serin des Canaries » de l’Histoire naturelle de Buffon. Il s’agit, dans un premier temps, d’examiner la signification sociale et culturelle de l’élevage de ces oiseaux à Paris au xviiie siècle, particulièrement populaire parmi les femmes aisées. Dans un deuxième temps, l’analyse se focalise sur l’article de Buffon pour montrer comment les descriptions scientifiques des différences sexuelles chez les animaux conduisent à la naturalisation des différences humaines, à travers ce que nous appelons un « cercle anthropocentrique de naturalisation ». Dans un troisième temps, nous montrons comment les deux catégories de sexe et de race sont construites l’une par rapport à l’autre dans l’histoire naturelle de Buffon et dans l’élevage des animaux de l’époque.
Abeilles, fourmis et brigandes
Authors: Carli Maddalena , Petrizzo Alessio
Published: October 2022

Au sein de la production de Cesare Lombroso, La Femme criminelle, ouvrage consacré à la criminalité féminine qu’il publie avec Guglielmo Ferrero en 1893, marque le moment où le criminaliste italien intègre de façon systématique l’univers animal dans ses explications de la déviance. Il mobilise alors une théorie générale de l’évolution centrée sur la féminité. L’article interroge le fonctionnement de ce dispositif sur le plan théorique et via un exemple précis : les brigandes. Il suggère que les stratégies textuelles et visuelles de représentation, notamment de virilisation dont ces femmes font l’objet sont étroitement liées à la théorie de la « supériorité primitive de la femelle » et de l’indistinction entre les sexes chez les espèces animales « inférieures ». Paradoxalement, l’atavisme des criminelles les rapproche donc des qualités des hommes, en reprenant de façon perverse le chemin évolutif que la « femme normale », « homme arrêté dans son développement », a interrompu.
Un débat historiographique
Authors: Amborg Jens , Kaibara Tomohiro , Sebastiani Silvia
Published: October 2022

Ce bilan historiographique porte sur la nouvelle conception du sexe qui se dessine au siècle des Lumières et ses liens avec le développement d’un type inédit de rapports entre humains et animaux dans les espaces métropolitains et coloniaux. Depuis une trentaine d’années, l’histoire des émotions et l’histoire des sciences de l’homme ont contribué à éclairer les conditions historiques dans lesquelles s’est constitué le paradigme anthropologique des Lumières. L’article identifie un certain nombre de thématiques – la domestication, l’émergence de l’animal de compagnie, la pratique de l’élevage sélectif – dont l’étude a permis de reconfigurer les approches du genre. En portant une attention nouvelle aux relations entre genre et animalité, ces travaux ont apporté une contribution décisive à la compréhension des débats savants et politiques des Lumières sur les frontières de l’humain et le binôme nature-culture.
Sœur Gertrude : une complicité de génocide
Authors: Bour Juliette
Published: October 2022

Entre avril et mai 1994, au couvent de Sovu au Rwanda, plusieurs milliers de Tutsi sont assassinés par des miliciens avec la complicité de la mère supérieure des lieux, sœur Gertrude. En 2001 à Bruxelles, la cour d’assises la juge et la condamne pour son implication dans les massacres. À partir des archives des transcriptions du procès, l’article revient sur la façon dont s’exerçait son autorité au sein du couvent au moment du génocide. Sa défense adopte une stratégie genrée et cherche à éloigner la sœur de la possibilité même de l’engagement dans la violence. Mais les témoignages des victimes attestent l’intégration de la religieuse aux réseaux politiques locaux et la manière dont elle a mobilisé les ressources à sa disposition pour exclure de la sphère de protection du couvent les Tutsis s’y étant réfugiés.

Authors: Sobral Ana Paula Barbosa , Oliveira Aline Rangel de , Lima Adalberto da Cruz , Silva Guilherme dos Santos , Fonseca Patrick Fernandes Ribeiro da
Published: October 2022

The objective of this work is to carry out a literature review on indicators for emergency and urgent healthcare units aimed to identify the main measures within the context of healthcare services. A search was conducted on the Scopus and PubMed databases using two strategies aimed to conduct research on studies about indicators for emergency and urgent healthcare units. This work allowed identifying the main indicators used in the context of emergency and urgent medical services, which are length of stay, left without being seen, national emergency department overcrowding scale, among others. In addition, it was found that such indicators provide suitable and viable means to assess, review, and display the quality of health systems. It was found in some studies that the use of indicators is used only as a measure whose value is monitored by systems, but it does not lead managers to an action plan.
Lean Practices and Assistive Technology in Emergency Care Units (UPA)
Authors: Ramos José Ricardo Souza , Braz Ruth M. Mariani , Pinto Sergio Crespo da Silva , Teixeira Adriana Melo , Zeferino Ana Carolina Sanches
Published: October 2022

This chapter deals with the application of lean and inclusive practices in order to mitigate the problems of the healthcare system in emergency care units (UPAS), especially when dealing with people with disabilities. The lack of qualified professionals, endless waiting queues causing overcrowding, waste, lack of supplies, and equipment are, among others, common “pathogenic” examples in the UPAS. The combination of practices and methods to combat waste and add value derived from Lean healthcare with the assistive technologies are fundamental for the adequacy of accessibility and improvement of care for people with disabilities. These practices provide mobility and autonomy to these patients, allowing their inclusion, improving their self-esteem and quality of life. The objective of this study was to investigate what is known about facilities and difficulties in the use of auxiliary devices, lean and inclusive methods, and practices to improve the care of people with disabilities in UPAS.
The Method of Applying Knowledge Management to Lean in Emergency Care Units
Authors: Barbosa Christiane Lima , Lima Adalberto da Cruz , Silva Maria Helena Teixeira da , dos Reis Milena Estanislau Diniz Mansur , Cosenza Harvey José Santos Ribeiro
Published: October 2022

This chapter analyzes Lean interventions in emergency care units (ECUs) with a focus on learning theory and knowledge management. The use of data served to understand the effectiveness of Lean methodology in transforming knowledge in ECUs. The method was a systematic and descriptive ex-post survey in the Lean project database, quantitative, and qualitative analysis aiming to establish relationships between the foci. The virtual platform is an effective tool for dissemination and generates reliable answers for analysis and decision making. The benefits of interventions through the use of Lean tools are unquestionable, visible, and useful for the daily life of the units. However, the internalization of the Lean culture for permanence and improvements is a point of attention as well as the content, form, and conduction of the actions. Committed people, management by processes, Lean flows, shared information, and agile communication are guarantees for the transformation and consolidation of the improvements.
Dialogues Between the National Humanization Policy and Lean Methodology
Authors: Silva Maria Helena Teixeira da , Amaral Laryssa Carvalho de , Silva Nilra do Amaral Mendes , Santos Gabriel Nascimento , Nascimento Stephanie D´Amato , Barbosa Christiane Lima
Published: October 2022

This chapter is the result of a project signed between the Universidade Federal Fluminense and the Ministry of Health in 2019 and executed in 2020. Its objective was to identify intersections of ideas between the national humanization policy (PNH) and the Lean methodology. The path used was to seek ideas in the Lean methodology similar to the ideas present in the principles of the PNH. These intersections are understood as opportunities for actions that consider both the reduction of waste and the strengthening of aspects of the humanization of health. The authors identified seven common ideas: focus on the customer, the importance of the collective as a space for transforming work, the importance given to the workplace, shared management of processes, user inclusion, transversality of both, acting in the way of thinking about work. The conclusion is that such coincidences exist and are opportunities to deepen the dissemination of the principles and guidelines of the PNH through the actions of the Lean methodology and vice versa.
The Murder of Sophie Toscan du Plantier and Its Implications for the Study of Media and Crime
Authors: O'Mahony Shane
Published: October 2022

Criminologists have often highlighted how the news media tends to disseminate simplified and stigmatised narratives to represent violence against women. Furthermore, these narratives often interweave with class-based fears, sensationalism, and mythology. However, recently, several authors have begun to examine the potential of new media sources (podcasts, documentary series, social media) to subvert these narratives. Drawing on a case study examining the murder of Sophie Toscan du Plantier in West Cork, Ireland (December 1996), the current chapter examines the ways in which three recent new media examinations of the case subvert and reinforce these narratives. The chapter demonstrates that while the new media sources foreground the victim's biography and background, give voice to her family, and situate the case within broader social and political contexts, they also reinforce class-based stereotypes relating to deserving and undeserving victims and problematically focus on the mythical elements of the case for entertainment purposes.
Corpus Delicti?

Corpus delicti, or body of evidence, is a fundamental to criminal prosecutions. This contribution takes a more literal perspective by exploring the ‘no-body murder'. Body disposal is not a single event; it is a complex process that dynamically responds to social and environmental circumstances. This contribution explores the legislative response to no-body murders through the Prisoners Act 2020 and presents six dimensions explaining non-disclosure of location of victim remains. Four high-profile no-body cases are presented, demonstrating the complexities inherent in searching for the long-term missing, presumed dead. This chapter focuses on the offender deposition strategy, the operational response, and environmental dimensions that explain prisoner non-disclosure and the failures to detect clandestine depositions.

The article presents the results of studies of the rheological properties of liquid geocement composite materials for protection against electromagnetic fields. It has been established that an increase in the concentration of a mixture of functional iron-containing fillers from 15 to 60 wt. % in the speed range from 0.1 to 1 rpm contributes to an increase in dynamic viscosity values from 100,000 to 550,000 cP. It’s noted that with an increase in the spindle speed from 15 to 35 RPM, the values of dynamic viscosity lie in the range of 8860-3442 cP. With the same concentration changes, the plastic viscosity of the liquid composite material in the speed ranges from 10 to 25 rpm changes, respectively, to 1064.5 cP, 3096 cP, 25462 cP, which is 1.04, 3, 03 and 24.9 times exceeds the value of the plastic viscosity of the original geocement paint. It is shown that at low shear rates from 0.02 to 0.3 l/s and an increase in the concentration of the filler mixture from 0 to 60 wt. % shear forces increase sharply on average from 21.2 to 252 dynes/cm2. Increase in shear rate from 0.315 to 7.35 1/s. Shear forces gradually increase from 76 to 252 dynes/cm2. It is shown that when the content of a functional filler with a concentration of 15% liquid composite material can be applied to the substrate by pneumatic spraying; with a concentration of 30% - with a brush or roller; with a concentration of 45 to 60% using a spatula. The total shielding coefficients of the electromagnetic field of industrial frequency by layers of a mixture with a thickness of 0.22-0.25 mm with a shielding substance content of 15-60% (by weight) for geopolymer paint is up to 8.6; shielding coefficients of the electromagnetic field of microwave frequencies up to 7.9. In the presence of filler up to 60%, the reflection coefficient of the electromagnetic field of ultrahigh frequency does not exceed 0.34, while the reflection coefficient of ultramagnetic waves of ultrahigh frequency as estimated at 0.20, and the experimentally measured one is 0.22-0.23.

Computational prediction of damage in cement-based composites, as steel fibre reinforced ones, under mechanical, thermal, etc. loads, manifested as creation of micro-fractured zones, followed by potential initiation and evolution of macroscopic cracks, is a rather delicatematter, due to the necessity of bridging between micro- and macro-scales. This short paper presents a relatively simple approach, using certain extension of the finite element technique, open to possible generalizations. Such model admits proper verification of its existence andconvergence results, from the physical and mathematical formulation up to software implementation of relevant algorithms. Its practical applicability is documented on computational examples.

Mg/Al bilayer thin films were successfully deposited by using D.C. magnetron sputtering technique. To study the effect of hydrogenation on structural, optical and electrical properties of Mg/Al thin films, the hydrogenation of the annealed thin films was done under different hydrogen pressure (15, 30 & 30psi). The structural properties of the films were investigated by Raman spectroscopy and decrease in intensity of Raman peaks with increasing hydrogen pressure was observed; this typically confirms the existence of hydrogen in Mg/Al thin films. The thin film is of semiconducting nature and it was found that the electrical conductivity of the film decreases with increasing hydrogen pressure applied. In the hydriding kinetics of the films, it was seen that the resistivity increased along with hydrogen absorption time. Eventually, it attains the equilibrium stage indicating the hydrogen absorption in the thin films. The rate of absorption of hydrogen increases with the pressure of hydrogen over different time ranges and decreases with the absorption of hydrogen over time.

Plant extracts have become an essential renewable resource and eco-friendly for many applications by using corrosion inhibition. In this study, the inhibitive activity of water concentrates of the Acacia nilotica with 0.5M H2SO4 stock solution at different concentrations, was studied using the Gravimetric Method. To know the improved impact on the consumption of mild steel, extracts of the plant were characterized by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM). SEM confirmed the formation of a protective layer on the surface of mild steel. Different techniques like UV-Visible and weight-loss analysis were studied to detect the organic natural compounds in the extract. Langmuir isotherm was fitted well for this study with a correlation coefficient (R2) of 0.999.

This article presents the results of a study on the effect of carbon nanosized additives on the structure and properties of cement-based materials. The use of a carbon black dispersion as an alternative to an expensive dispersion of carbon nanotubes is proposed. Based on the experimental data, it is proven that the introduction of carbon black particles into the composition of the cement matrix in an amount of 0.2% by the weight of cement leads to an increase in strength of the cement stone, in both compression and bending, by 21% and 8%, respectively. This increase is compatible with the results obtained when cement matrix was modified with a dispersion of carbon nanotubes.IR spectral and thermal analysis of the modified cement matrix, as well as the study of its microstructure, confirm the formation of a dense net of cement hydration products, including low-basic calcium silicate hydrates and secondary nanosized globular thaumasite formations that contribute to the compaction of the material structure and the following increase in strength.

Applications of harmless fluid derivative for the sustenance of carbon steel in corrosive environments are more appropriate for environmental sustainability and safety of personnel. Admixture of grapefruit and lemongrass distillates was assessed for their protective performance on plain carbon steel within 0.5 M of H2SO4 and HCl solution through weight loss analysis and optical macroscopy studies. Results shows the plant extracts effectively stifled corrosion in both acids with inhibition value range (lowest to highest) of 98.65%-99.5% in H2SO4 solution and 96.31%- 98.39% in HCl. PCS in H2SO4 and HCl electrolyte at 0% extract concentrate were 5.330 mm/y and 2.701 mm/y. Inclusion of the distillate to the electrolyte significantly reduced the corrosion rates in both acids to midpoint values of 0.0448 mm/y and 0.072 mm/y at 240 h of test. The oil extract strongly adsorbed unto the steel surface by means of chemisorption with midpoint Gibbs free energy value above -44 Kjmol-1 signifying strong covalent bonding. The extract adsorption aligned with Langmuir and Frumkin adsorption isotherms with interaction coefficient above 0.9. Optical images of steel surface without inhibitor showed a severely corroded morphology and significant reduction in thickness. The protected steel substantially differs the earlier observation due to the presence of the oil extract which passivated the steel exterior.

Published: October 2022

The catastrophe failures of the underground water pipelines, made by Fe-alloys have been largely reported in Nepal, mostly due to the unwanted electrochemical interactions in the interfacial regions between the aggressive soils and external pipe surfaces. To cope with such pipe corrosion, this study was put forward a novel probabilistic approach for the proximate analysis of the corrosive grade of soils to the pipes with the improvement of the previously practiced ASTM, AWWA, and NACE classifying methods. In this non-deterministic approach, four corrosive groups were firstly classified based on the quantitative data of 6 soil properties, which were further classified into ten sub-corrosion groups by considering the sum of the cumulative point of each soil sample. The proximate soil analysis of twenty-four samples of the Sanagaun-Imadol (SNG-IDL) and Kantipur (KNT) housing areas of Lalitpur metropolitan (Kathmandu Valley) was performed to evaluate their corrosion conditions and to draw a corrosive soil mapping. The results of such proximate analysis under the probabilistic approach disclosed that ~ 92% of the total 24 soils of the study areas belonged to five specific sub-corrosion groups, which are considered the members of two corrosion groups, i.e., less and mildly corrosion groups.
