Because of its exceptional qualities, aluminium composites are frequently employed in aircraft applications. Aluminium alumina composite was manufactured in-situ using the AA-6061 T6 matrix alloy and 3 %age, 6 %age (Nichrome) powder. Optical metallography, Image Analysis, and micro hardness tests were used to assess the in-situ composites. The specimens then liquid preheated at 550 °C for 3 hours and then aged at 180 °C for 7 hours to improve the durability in mechanical characteristics. In comparison to the as cast samples, the heat-treated samples showed significantly higher mechanical properties. AA-6061 T6 matrix composite reinforced with in-situ alumina particle with TiC was also studied for grain refining. The Al-4.5 % Ti-1.5 % C master alloy has been shown to be an effective grain refiner.

Plain carbon steel is the cheapest and most readily available metal in Nigeria for agri-tech processing equipment. It is used for its low cost and ease of access. They are, however, vulnerable to corrosion due to their use in a corrosive medium, such as fluid extracted from cassava tubers. The corrosion resistance of heat-treated mild steel and Chromium-plated mild steels used as tools in the cassava processing environment was investigated in this study. The untimely failure of this material while in service is caused by malignant ions found in food and raw farm products, which attack the steel components, causing gradual failure of the processing machinery. According to the findings of this study, annealed mild steel materials, whether coated or uncoated, are preferred. The study results revealed that the control annealed mild steel sample has the lowest corrosion rate of 0.027 mm/yr, while the corrosion rates of the heat-treated hardened, normalized, and tempered samples increase by 0.054, 0.067, and 0.10 mm/yr, respectively. The effect of coating time on the amount of chromium deposition was reflected in chromium-plated heat-treated samples that were heat-treated for 10 to 20 minutes at 5 minutes intervals. The corrosion rate was lowest in annealed chromium-plated samples, with an average grain size of 118.46 um and a corrosion rate of 0.04 mm/yr. According to the findings of this study, annealed mild steel materials, whether coated or uncoated, are preferable for use in the cassava processing operation.

Three forms of Saccharum munja had been utilized for a comparison among uptake of chromium metal from aqueous media. Scanning electron microscope characterization of sorbents revealed microporous and tubular structure in modified nanomaterial. Fourier transform infrared analysis explored different surface attaching ionic groups like hydroxyl, carbonyl also nitro groups, responsible for metal uptake from solution. Experiments on concentration factor suggested maximum percent sorption capacity of 89.65 by hematite loaded Saccharum munja biochar. Adsorption equilibrium data implication on isotherms and error functions favored experimental findings. Calculation of two forms of different isotherms for example Dubinin-Radushkevich, Langmuir, Temkin and Freundlich isotherm supported adsorption experiments with high R2>0.9 values for all sorbents. Error analysis indicated favorable results by five errors but chi-square test error values were minimum in both linear data and non-linear data. Kinetic modeling results indicated high rate of adsorption as shown by their large R2 value and closely related k, Qe and h values. Thermodynamic results showed that biosorption reactions were endothermic and spontaneous. These results also suggest that hematite loaded nanomaterials are good biosorbents for chromium metal uptake in minimum concentration and high output. Desorption study was essential for recovery of nanomaterial to be used again and again in experiments.

Authors: Yussif Ben Kudus , Imoro Ibrahim
Published: March 2022

Socio-phonetically, the study seeks to investigate the realization of RP phonemes /r/ and /l/ among Asante English speakers in Ghana focusing on the level of education of participants. Using stratified proportion of 1:1:1 for a total of 30 participants, each of the educational groups (Basic, Secondary and Tertiary) consisted of 10 participants who lived and studied in Kumasi, Ghana. The data was analysed using acoustic and auditory tool (PRAAT 6104) and followed by Analysis of Variance (ANOVA) using SPSS version 20. The study revealed that the phoneme /r/ can be realized as [r], [l] and linking [r] while the phoneme /l/ is realized as clear [l], dark [?] and linking [l]. The findings indicated that participants level of education significantly impact their choice of specific variants of /r/ and /l/. The study also revealed that the nonstandard realization of the phoneme /r/ as [l] is dominant among basic school children but significantly reduces as they progress from basic through tertiary education.
Society Versus the Desires of Women in Madame Bovary and Grihadaha: The Scandalous Woman Conundrum
Authors: Hasan Md , Ahsan Mohsina , Saiyara Naziba
Published: March 2022

This research paper attempts a comparative study between Sarat Chandra Chattopadhaya’s novel Grihadaha and Gustave Flaubert’s Madame Bovary. The exploration involves a comparative analysis of the dreams and desires of the female protagonists in relation to the social and cultural norms of the times in which the novels are set with an intention to evaluate how the respective societies treat these women. Initially, both texts were closely read and analyzed separately for better understanding. Then the texts were read comparatively to identify the similarities and the differences. The study led to the discovery that be it the conservative Bengali society or the comparatively lenient French society, the pursuit, and fulfillment of the dreams and desires of women are always restricted in favor of patriarchy. Men enjoy privileges that are not offered to women and societies are often inherently hypocritical and unjustifiable.

“Our Voices Matter”: The Learner Profile of UTech, Jamaica Students and Implications for a Virtual Self-Access Learning Centre
Authors: Telfer Daidrah , Stewart-McKoy Michelle , Burris-Melville Tashieka , Alao Maribel
Published: March 2022

Since the establishment of the Self-Access Learning Centre (SALC) at the University of Technology, Jamaica (UTech, Ja.), students, particularly those enrolled in academic writing modules, have been utilising it to improve their communicative competence. However, the centre has recently encountered various challenges, chief among which are the lack of resources and restricted access to students, pushing the centre to the brink of obsolescence. This led to a revisioning of the centre, a central part of which is the creation of a virtual learner-driven SALC that focuses on the key areas in English and writing that students find challenging. For such a centre to be effective, it needs to be founded on students’ demographic, psychographic and behavioural traits.

Using the results of a cross-sectional survey of 278 UTech, Ja. students, we present a learner profile of the typical student and the implications of such a profile for the creation of the virtual SALC. The results reveal that the typical student is teacher-dependent, extrinsically motivated and possesses low levels of academic exertion, low capacities for independent work and high levels of technology consumption. Based on this profile, heavy use of images, games and gamification elements, auto-rated activities, and interactive tutorials are central to the VSALC.

Sustainable Integrative Framework for Biodiversity Conservation and Pastoralists’ Resilience to Impact of Climate Change in Northern Tanzania Rangelands
Authors: Joseph Laurent
Published: March 2022

This study aimed at developing a sustainable integrative framework for biodiversity conservation and pastoralists’ resilience to impacts of climate change (SIBCPRF) The SIBCPRF was developed after assessing the impacts with a high rate on the pastoralists in northern Tanzania rangelands. The study used different approaches and methods for data collection: exploration of secondary information, observation, household survey, structured interview and focus group discussion. The sample included 312 respondents. The study revealed that climate change has impacted the biodiversity and pastoralists’ livelihoods in many ways like shortage of water, death of livestock, the rise of conflicts, and migration. In turn, the study discovered that the pastoralists have been adapting and resilient to the impact of climate change by adopting various strategies like control of animal reproduction, use of by-laws, use of ingaron system (enclosure of a place for some time), and migration from one place to another with livestock for the search of pasture and water. However, the strategy seems to have shortcomings such as to cause of conflict with neighbours, farmers, separation of families, and death of livestock due to a long walk distance. The study concludes that it is important for the pastoralists’ communities to resilient and adapt to impacts of climate change so as to conserve the biodiversity and for their well-being. This can only be done if there is a clear tool guiding them on how to sustainably resilient and adapt. It is from this perspective the SIBCPRF was developed to properly address the highest-rated impacts of climate change during dry seasons. The SIBCPRF to climate change developed considered Ecosystem-based Approach (EbA), Impact Specific Approach (ISA), and the Enclosure System (ES). The formulation of SIBCPRF assumes that it is the role of each community to address climate change risks by implementing the appropriate strategies and plans provided to them (pastoralists).

Macro- to nanoscale mineral relationships in surficial cobalt-arsenic-bearing mine tailings of the Cobalt Mining Camp, Northeastern Ontario, Canada
Authors: Courchesne Brittaney , Schindler Michael , Lussier Aaron J. , Mykytczuk Nadia
Published: March 2022

Arsenates, which correspond to the majority of known arsenic (As)-bearing minerals, control the mobilization of As in contaminated soils, sediments, and fluvial environments as well as in tailings and mine waste piles. Additionally, arsenate-bearing Fe-(hydr)oxides are of particular significance for the control of As mobility, as they are among the most thermodynamically stable minerals under near-neutral to alkaline pH conditions. However, in the surficial (upper 30 cm) alkaline mine tailings at the Cobalt Mining Camp in Northeastern Ontario, Canada, these phases only occur in trace amounts. This study attempts to understand this unusual mineralogical feature through an investigation of the relationships between nano- and macroscale mineralogical and geochemical features at two tailings sites (A and B) at the Cobalt Mining Camp. Sixty samples from two depth profiles (0–30 cm; i.e., one sample per centimeter) were collected at the two sites, analyzed for their major and minor chemical elements, and characterized for their mineralogical composition at the nano- to centimeter scale. The tailings material at both sites is predominantly composed of minerals of the amphibole, chlorite, and feldspar groups, as well as carbonates (calcite and dolomite). Minor phases are Co-Fe-Ni-Zn-sulfarsenides and -arsenates. The tailings material at site B contains, on average, higher concentrations of As, Co, Sb, and Zn and lower concentrations of Fe than the material at site A. Secondary (scanning electron microscope) and transmission electron microscopy studies indicate that the alteration of primary sulfarsenides to secondary arsenates may proceed in the following sequence: (1) the formation of Fe-hydroxide and -arsenate mineral surface coatings on sulfarsenides; (2) the downward mobilization of Co-Ni-Zn-arsenate and (FeOHCO3)aq species; (3) replacement of earlier-formed scorodite by Co-Ni-Zn-arsenates; (4) the precipitation of Co-Ni-Zn-arsenates on the surfaces of silicates; and (5) neoformation of Fe-rich hydroxy-interlayered minerals at greater depth, partly replacing earlier-formed Co-Ni-Zn-arsenates. These processes result in layers enriched in As, Co, Sb, and Zn (increase in Co#) and enriched and depleted in Fe (increase and decrease in Fe#) in tailings material at both sites. The TEM studies further indicate that Co-Ni-Zn-arsenates precipitate initially as nanoparticles on the surface of scorodite and detrital silicates and subsequently coarsen through Oswald ripening. The mineralogical-geochemical features depicted in this study provide a better understanding of the geochemical behavior of Co, Fe, and As in alkaline tailings and may assist in the interpretation of mineral-microbial community associations and the development of effective bioleaching strategies for the strategic element cobalt.
Palaeogene glendonites from Denmark

Pristinely preserved mineral pseudomorphs called glendonites, up to 1.6 m long, from the Palaeogene strata of Denmark allow detailed crystallographic characterisation and add to the understanding of the transformation of the precursor mineral, ikaite (CaCO3·6H2O), to calcite, which constitutes the glendonite. We describe Danish pseudomorphs after ikaite from two localities and formations: the Early Eocene Fur Formation and the Late Oligocene Brejning Formation. This detailed study highlights that key aspects such as morphology and mode of occurrence of these ancient glendonites are identical to those of their parent mineral ikaite, when it grows in marine sediments. Systematic distortion of the angles in glendonite and marine sedimentary ikaite relative to the ideal ikaite symmetry may arise due to the incorporation of organic matter into the crystal structure, and we demonstrate the similarity between modern and ancient ikaite formation zones in the marine sedimentary realm with respect to organic matter.
Ameliorative Potentials of Justicia Carnea and Cnidoscolus Aconitifolius on the Fecundity of Chloramphenicol-Induced Lymphoma Rats
Authors: Minaopunyea Onyegeme-Okerenta Blessing , Chimeziea Omeje Henry
Published: March 2022

Justicia carnea and Cnidoscolus aconitifolius were tested for their capacity to ameliorate the fecundity of chloramphenicol-induced lymphoma in rats. Seventy male Wistar rats weighing an average of 128g were randomly divided into 14 groups of five rats each. Group 1 was provided with commercial rat diet and water on a daily basis. For 28 days, rats in groups 2-14 received 250mg/kg bodyweight chloramphenicol by oral intubation. Group 2 received no therapy and is thus referred to as the negative control group. The remaining groups (3–14) received aqueous leaf extracts of J. carnea (ALEJC) (Groups 3-6), C. aconitifolius (ALECA) (Groups 7–10), or a combination of both extracts (Groups 11–14) at dosages of 500mg/kg, 1000mg/kg, 1500mg/kg, and 2000mg/kg, respectively, for 28 days. After anaesthesia with ether, blood was drawn from the retro-orbital venous plexus to determine the activities of oxidative stress indicators such as superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and glutathione (GSH). The testes were dissected for histological inspection and the semen were collected for analysis. The results indicated a significant (p0.05) increase in weight across groups, as well as a reduction in sperm volume, viability, and motility in group 2 animals as compared to group 1. SOD and GSH levels increased significantly, but MDA levels increased in a non-significant (p>0.05) manner. The results indicated that the extracts had a beneficial impact on infertility associated with excessive chloramphenicol exposure.

Araştırmaya dâhil edilen dokümanların incelenmesi sonucunda 9. sınıf düzeyi kimya dersi konularına yönelik toplam 338 yanlış kavrama belirlenmiştir. Bu yanlış kavramalar analiz edildiğinde en sık yanlış kavramanın “Atom ve Periyodik Sistem” ünitesi ve bu ünite altında anlatılan “atom” kavramıyla ilgili olduğu sonucu elde edilmiştir. Araştırmaya ait bulguların, yanlış kavramaların oluşumunun engellenmesi ve dolayısıyla bilimsel bilginin doğru yapılandırılması açısından alana önemli katkılar sağlayacağı düşünülmektedir. Ayrıca çalışma sonuçları, kimya öğretmenleri ve öğretmen adaylarının 9. sınıf kimya konularındaki yanlış kavramalardan haberdar edilerek öğrencilerinde bu yanlış kavramaların oluşmaması için önlem almaları konusunda da yardımcı olabilir.
A Murchison Widefield Array Search for Transmissions from the 4M Spacecraft, On Board the Chang’e 5-T1 Booster, Prior to its Predicted Collision with the Moon

Using the Murchison Widefield Array we searched for, and did not detect, 145.980 MHz transmissions from the 4M spacecraft attached to the Chang’e 5-T1 rocket booster. This object was predicted to collide with the Moon on 2022 March 4. We observed for a ten minutes period on 2022 March 1, achieving noise levels of ∼4 Jy in a 10 kHz bandwidth. The expected signal level of a nominally operational transmitter would be ∼7500 Jy. Thus, we conclude that the transmitter was inactive (or operating at less than 5 mW) in the days before the predicted impact with the Moon, which is reasonable given that the nominal mission life of 4M was approximately 8 days in late 2014. A detection would have allowed 4M and its host booster to be tracked to near the point of collision, which was not possible using optical telescopes due to the event occurring in daytime.

Ce chapitre propose un témoignage à quatre mains de deux intervenants-chercheurs nouvellement intégrés par le centre de recherche ISEOR après respectivement 6 mois et 20 mois de stage. Ils nous proposent le récit des premiers mois de leurs intégrations, leurs surprises et les spécificités des méthodes de travail du centre de recherche. Il y est détaillé en particulier l’apprentissage de l’exemplarité, la recherche du point d’équilibre entre l’autonomie et la concertation ainsi que leur analyse du processus d’intégration et de ses effets.

Ce chapitre explore deux pistes d’évolution possible et souhaitable dans le secteur de la formation professionnelle en France, par des convergences normatives et des articulations de normes. La première se situe dans un plan systémique appréhendant un temps long, ce qui permettrait de concilier le parcours de vie d’un salarié. La seconde est dans un niveau plus opérationnel se fondant sur une recombinaison d’ingénierie articulant le capital humain et le capital économique. La cohérence du parcours de vie pourrait être améliorée en faisant converger les métiers des Opérateurs de compétences (Opco) et des Groupes de protection sociale (GPS) en imaginant créer des Groupes opérant sur le Parcours de Vie (GPV). Puis il s’agit de concevoir une expérimentation Région/Opco visant à explorer l’unification simultanée du capital économique et du capital humain.

Dans la décennie 1980 les réformes mises en œuvre par les bailleurs de fonds internationaux dans les pays subsahariens ont consisté généralement à transplanter des méthodes de management considérées comme universelles. Le recours à la méthode socioéconomique, par la prise en compte des spécificités du contexte, a permis de rendre les réformes plus appropriées et plus acceptables. Après l’examen des problèmes posés par les réformes, la présentation de quelques activités mises en œuvre dans le respect des valeurs très proches de celles de l’ISEOR montre comment le management socioéconomique peut être un levier d’action pour les pays du Sud.

L’entreprise est un corps social soucieux de sa survie, avant même de viser une rentabilité ou une croissance. Son organisation comme ses choix seront influencés par cet impératif. Les menaces contre cette survie, telles que le risque croissant d’attaque informatique, étant peu mesurables ex ante par les décideurs, engendrent une incertitude qui nuit à une allocation optimale des ressources, et causent en cela des coûts cachés. Au surplus, la simple éventualité d’une telle attaque, pesant de manière diffuse sur les processus et la fonction décisionnelle de l’entreprise, abaisse sa performance et sa cohésion.

Le traitement amiable et judiciaire des entreprises en difficulté est en France un domaine très peu connu dans le monde de l’analyse socio-économique. Pourtant, il est un moment où l’on priorise la recherche des coûts cachés tout d’abord par une restructuration sociale toujours urgente, inévitable et indispensable (article L.631-17 du Code de Commerce) puis ensuite par un enrichissement des tâches des salariés qui restent pour conduire à des gains très importants de productivité (+ 30% en moyenne).

Depuis un demi-siècle, les « connaissances scientifiques et techniques » étaient d’une rare abondance. Pourtant, l’humanité en est venue à mettre en péril ses conditions réelles de survie ! Les pensées économiques et de gestion ont-elles quelque chose à voir avec ce fiasco ? Ou avec une si grave absence de politique générale ? Comment discerner des pistes d’une pertinence retrouvée, à élaborer en commun ?

Nous soutenons que l’approche socio-économique de la gestion (SEAM) est extraordinairement efficace pour améliorer la performance organisationnelle, en grande partie grâce à ses stratégies de collaboration couplées à des méthodes de recherche organisationnelle hautement rigoureuses. Nous analysons les méthodes de collaboration de l’intervention socio-économique à travers notre propre vision du « storytelling d’ensemble ». En utilisant cette grille de lecture, nous trouvons des preuves de cinq (5) formes de storytelling d’ensemble pertinentes pour l’intervention socio-économique.

Ce chapitre analyse l’écosystème organisationnel actuel dans lequel les êtres humains opèrent. Elle place l’être humain au centre de l’action, sous l’hypothèse que s’il travaille dans des conditions de confiance, de liberté d’agir et de pouvoir, il deviendra l’agent de changement dont l’entreprise a besoin pour faire face aux défis d’aujourd’hui. La conclusion la plus importante est que le modèle de gestion socio-économique, comme l’agilité organisationnelle, est constitué de concepts de gestion nés et développés dans des contextes volatils, incertains, complexes et ambigus.
Les césariennes non nécessaires et la violence obstétricale au Mexique : une visibilité et des résonances croissantes
Authors: Márquez Murrieta Alicia
Published: March 2022

La catégorie de « violence obstétricale » existe depuis plusieurs années sur la scène juridique et publique au Mexique. Parmi les pratiques relevant de ce domaine, l’augmentation du recours à la césarienne nourrit depuis des décennies une réflexion sur le genre de considérations qui poussent à favoriser une intervention chirurgicale au détriment de l’accouchement par voie basse, et provoque des controverses dans plusieurs scènes publiques. Sont ici analysés des articles écrits par des spécialistes dans deux revues mexicaines Salud Pública de México et Género y Salud en Cifras . Le but est d’observer, à partir de cette analyse, l’évolution des conceptions des césariennes au cours des dernières décennies et de comprendre les questionnements sur l’augmentation de ces actes et les motifs (médicaux et non médicaux) qui ont sous-tendu cette décision, de repérer les profils des femmes concernées et l’émergence progressive du discours sur le risque à subir ce type d’intervention. On constate que la recherche sur l’augmentation du nombre de césariennes a effectivement gagné en importance, surtout celle portant sur les critères non médicaux, mais aussi que les deux revues analysées rattachent rarement leurs réflexions à la catégorie de « violence obstétricale ». Entre autres choses, nous avons pu remarquer l’amplification graduelle du discours sur le risque, ainsi que la mise en place d’une approche consistant à inclure, parmi les facteurs de risque pour l’accouchement, le fait d’être candidate à une césarienne sans justification médicale précise.
On the number of solutions of two-variable diagonal sextic equations over finite fields
Authors: Hu Shuangnian , Feng Rongquan
Published: March 2022

Let $ p $ be a prime, $ k $ a positive integer, $ q = p^k $, and $ \mathbb{F}_q $ be the finite field with $ q $ elements. In this paper, by using the Jacobi sums, we give an explicit formula for the number of solutions of the two-variable diagonal sextic equations $ x_1^6+x_2^6 = c $ over $ \mathbb{F}_q $, with $ c\in\mathbb{F}_q^* $ and $ p\equiv1({\rm{mod}} \ 6) $. Furthermore, by using the reduction formula for Jacobi sums, the number of solutions of the diagonal sextic equations $ x_1^6+x_2^6+\cdots+x_n^6 = c $ of $ n\geq3 $ variables with $ c\in\mathbb{F}_q^* $ and $ p\equiv1({\rm{mod}} \ 6) $, can also be deduced.

In the context of the COVID-19 global pandemic and the health measures derived from it, emergency online learning (EOL) became the only possible alternative to be able to continue the training process in the university context. The general ob-jective of the present research is to know the perceptions and evaluations of stu-dents at a Chilean public university about the "emergency" online learning pro-cess that occurred in the context of the COVID-19 pandemic. Based on several previous works related to online learning (OL), an instrument (questionnaire) was developed and implemented with the participation of 117 students. The re-search is quantitative-descriptive and had the following specific objectives: (1) To determine the attitude of university students towards EOL; (2) To characterize the learning experience of students in online modality; (3) To know about the availa-ble resources of students for EOL; and (4) To validate the developed questionnaire through a factor structure analysis. In general, the results show that students are proficient in the aspects related to self-management of learning, but have a low level of motivation for EOL and suffer a deficit in aspects related to interac-tion with others (teachers and peers). These results provide a first approximation of Chilean students' perceptions of EOL and allow us to identify several aspects that should be improved by professors and university authorities. This research was financially supported by the German Academic Exchange Service (DAAD as part of the project “Praxispartnerschaften zwischen Hochschulen und Un-ternehmen in Deutschland und in Entwicklungsländern ab 2017” (Project Nr. 57334905).
Identifiable Challenges as Global Complexities
Authors: Policek Nicoletta
Published: March 2022

Discourses on globalization and violence often fall short on understanding the gender aspects of different forms of violence. This is particularly the case for stateless women and girls, faced with the existing institutionalized systems of social and legal protection which do not account for them, making them almost invisible. Subsequently, this contribution claims that the assessment of vulnerability, and likely responses, are linked to power and identity at the global levels. Furthermore, such responses are shaped by the structure of agency and associated power structures in society. Unequal power structures are likely to lead to unequal patterns of neglect, or perverse responses that protect entrenched interests aligned with existing structures of identity or influence. In this way, the “vulnerability of stateless identity” can itself be a source of heightened anxiety and fear.
