Published: June 2021

Abstract
We present a general synthesis of transition metal difluorides (TMF2)–carbon nanocomposite films by magnetron co-sputtering the Fe/Co and polytetrafluoroethylene (Teflon) targets. The composites consist of binary TMF2 (TM = Fe, Co) nanoparticles with a crystallite size of ∼8 nm immersed in a carbon matrix. The antiferromagnetic nature of TMF2 nanoparticles with the Néel temperature T
N of 40 K (TM = Co) and 78 K (TM = Fe) is confirmed. The ability to create the sputter-deposited TMF2–carbon nanocomposites may not only allow for possible energy applications but also provide a platform for investigating the particulate disordered antiferromagnets.

Model-Model Pembelajaran Pondok Pesantren dalam Meningkatkan Kemampuan Membaca Kitab Kuning Santri
Authors: Muzammil Muzammil , Prastika Lindi 
Published: June 2021

Kitab-kitab Islam klasik biasanya dikenal dengan istilah kuning yang terpengaruh oleh warna kertas. Kitab-kitab itu ditulis oleh Ulama zaman dulu yang berisikan tentang ilmu keislaman seperti Fiqih, Hadits, Tafsir maupun tentang Akhlaq. Ada dua esensinya seorang santri belajar kitab-kitab tersebut disamping mendalami isi kitab maka secara tidak langsung juga mempelajari bahasa Arab sebagai kitab tersebut. Oleh karena itu seorang santri yang telah tamat belajarnya di pesantren cenderung memiliki pengetahuan bahasa Arab. Hal ini menjadi ciri seorang santri yang telah menyelesaikan studinya di pondok pesantren, yakni mampu memahami isi kitab dan sekaligus juga mampu menerapkan bahasa kitab tersebut menjadi bahasanya.
Santri adalah orang yang menerima ajaran-ajaran Islam dari para Kiyai dan para Kiyai juga belajar Islam dari guru-gurunya yang sanadnya terhubung sampai Rasulullah SAW.

Published: June 2021

Sorghum is being produced primarily as a food grain throughout the world. It is one of the major traditional food crops in Ethiopia. However, the productivity of the crop is very low and poor seed quality is one of the major determinants. An experiment study was conducted in laboratory and glasshouse to evaluate the effect of seed priming on seed quality parameters of three sorghum varieties:(Muyra-I, Muyra-II and Fendisha) with different storage of one year and two years using different priming agents with different soaking time for each priming agent (1.0mM KNO3, 1mM NaCl and distilled water for 72, 48 and 12 hours respectively) in 2012 at Haramaya University Seed laboratory. Completely randomized design in 2 x 3 x 4 factorial arrangement with three replications was used to carry out the germination and vigor tests. The priming concentrations and durations were based on previous work, which was effective in hydro and osmo-conditioning of sorghum seed. In the experiment, seed priming increased germination percentage (GP), Mean Germination Time (MGT) and improved seedling shoot (SSL) and root length (SRL), seedling dry weight (SDW) and seedling vigor indices in all varieties of both storage durations compared to their respective control. Priming with NaCl and KNO3 showed positive response followed by hydropriming for all varieties of different storage duration. When treated with sodium chloride, almost all the varieties of each storage year demonstrated an increase in germination and the degree of increment was higher for Muyra-I(__) and Fendisha (___), the lowest being for Muyra-II which was significantly lower for both storage year. In case of mean germination time Fendisha exhibited better with hydropriming for older seeds (___) and with KNO3 for newer seeds(___) while Muyra-II and Muyra-I showed better with KNO3 (____) for older seeds and with hydropriming for newer seeds. Responses of varieties for the remaining parameters were intermediate. Therefore, sorghum seed priming with osmo-media and water can compensate storage deterioration of sorghum seeds in addition to significantly improving the seed germination and vigor quality parameters

« Enfants d’ailleurs ». La protection de l’enfance à l’épreuve des migrations juvéniles internationales
Authors: Marmié Cléo 
Published: June 2021

Depuis les années 1990, la protection de l’enfance, dans ses modalités publiques, humanitaires et militantes, se voit mise à l’épreuve par l’intensification des flux migratoires juvéniles. À la fois étrangers et mineurs , désignés par la catégorie des « mineurs non accompagnés » ( mna ), les jeunes qui migrent « seuls » brouillent les contours de l’aide à l’enfance et perturbent les dispositifs de prise en charge traditionnels. Cette contribution interroge les effets de leur désignation comme groupe catégoriel et spécifique de l’enfance en danger sur les représentations et les pratiques de protection. Elle cherche à saisir, dans un contexte d’internationalisation des droits de l’enfant et de durcissement du contrôle migratoire, les reconfigurations de la protection de l’enfance, caractérisées par une tension entre une éthique du prendre soin et une injonction paradoxale au tri et au contrôle.

L’étonnement : un vecteur didactique en formation professionnelle
Authors: Thievenaz Joris , Piot Thierry 
Published: June 2021

Alors qu’en philosophie la démarche d’étonnement est depuis toujours considérée comme le préalable de tout acte de pensée et de production de nouveaux savoirs, cette notion demeure curieusement à l’écart du champ de la formation. Nous montrons dans cette contribution comment « susciter et accompagner l’étonnement » constitue pourtant un puissant levier didactique permettant d’encourager l’émergence de nouveaux apprentissages chez l’apprenant. Il s’agit d’étudier plus spécifiquement les usages concrets qui découlent de cette notion. Nous inscrivons pour cela cette réflexion dans une approche pragmatiste de l’expérience (Dewey, 1938) et appuyons nos propos sur des études de cas issues de dispositifs d’accompagnement d’élèves-stagiaires lors du débriefing du retour de stage en Institut de Formation en Soins Infirmiers (IFSI).
Quelles dimensions didactiques dans quelques travaux empiriques se réclamant de la didactique professionnelle ?
Authors: Métral Jean-François 
Published: June 2021

La didactique professionnelle exprime une visée didactique dans sa dénomination. Or plusieurs auteurs font le constat que la dimension didactique serait en fait limitée dans les travaux empiriques dans ce champ de recherche. Dans ce texte, nous utilisons les propositions de Jean-Louis Martinand pour caractériser une didactique afin d’analyser des travaux empiriques significatifs en didactique professionnelle et montrons comment ils abordent et traitent des problématiques propres aux didactiques : étude du point de vue des contenus ; question de la référence et de la transposition didactique ; approche épistémologique et obstacles à l’apprentissage.
Proof of Laugwitz Conjecture and Landsberg Unicorn Conjecture for Minkowski norms with -symmetry
Authors: Xu Ming , Matveev Vladimir S. 
Published: June 2021

AbstractFor a smooth strongly convex Minkowski norm$F:\mathbb {R}^n \to \mathbb {R}_{\geq 0}$, we study isometries of the Hessian metric corresponding to the function$E=\tfrac 12F^2$. Under the additional assumption thatFis invariant with respect to the standard action of$SO(k)\times SO(n-k)$, we prove a conjecture of Laugwitz stated in 1965. Furthermore, we describe all isometries between such Hessian metrics, and prove Landsberg Unicorn Conjecture for Finsler manifolds of dimension$n\ge 3$such that at every point the corresponding Minkowski norm has a linear$SO(k)\times SO(n-k)$-symmetry.
Youth clubs’ contributions towards promotion of Sexual and Reproductive Health Services in Machinga District, Malawi
Authors: Muula Adamson , Lusinje Alinafe C. , Phiri Chetimila , Majawa Prisca 
Published: June 2021

Background: In Malawi more than 50% of the population are young people less than 24 years old. Adolescents and young people face a lot of sexual and reproductive health (SRH) challenges such as unplanned and early pregnancies, sexually transmitted infections (STIs) including HIV and AIDS and abusive intimate relationships. Provision of SRH services through Youth clubs is one strategy that has potential to contribute to addressing the SRH challenges. We conducted a study in Machinga district, southern Malawi to assess the contributions of youth clubs towards promotion of SRH services.Methods: A cross sectional study was conducted in 2014 among youths aged 15 – 24 years. The participants were drawn from Machinga boma and Liwonde Township. We used both quantitative and qualitative methods. Quantitative data were collected using questionnaires, while Focus Group Discussions (FGDs) and Key informant interviews were used to collect qualitative data. Quantitative data were analysed by estimating proportions and Chi square tests while thematic content analysis was used for qualitative data. The study was approved by University of Malawi’s College of Medicine Research and Ethics Committee (COMREC).Results: Frequently offered services in youth clubs were HIV and AIDS education reported by 48.4% of the study participants, STI education (16.7%), family planning(16.7%) and life skills education (9.7%). On service utilisation there was no association between attendance to youth clubs and HIV Testing Counselling (χ2 =0.76, p=0.4) and there was no association between attendance to the youth clubs and family planning utilisation (χ2 =3.1, p=0.3). Condom use was the most used contraceptive method among the study participants. Misconception, accessibility and poor attitude of health workers were some of the factors reported as contributing to low utilisation of family planning methods. All youth club participants, reported by 89 study participants and only 29.4% of club non-attendees had adequate SRH knowledge. The services provided by health workers to youth clubs reported by study participants were HIV and AIDS education, HIV testing and counselling (HTC) and condom distribution.Conclusion: Our findings highlight the need of youth clubs to promote SRH services.Efforts should be made to ensure that the identified challenges are dealt with to ensure effective participation of youth clubs.

Published: June 2021

Background: Comminuted femoral shaft fractures are complex to treat because of increased risk of limb length discrepancies and mal-rotation deformities. Currently the interlocking intramedullary nail using image intensifiers is a suggested treatment for comminuted femoral shaft fractures. This study aimed to evaluate the short-term outcome of patients with closed comminuted femoral shaft fracture treated with locking intramedullary SIGN nail without image intensifiers at Muhimbili Orthopaedic Institute (MOI) in Tanzania.Methods: A prospective hospital base study was conducted on patients with closed comminuted femoral shaft fractures admitted at MOI from March 2011 to February 2012. A total of 91 adult patients (18 to 84 years) were enrolled in the study. Of the total patients, 80 (88%) patients were male, 11 were lost to follow-up, and 80 patients completed follow-ups of 18 weeks post operatively. Structured questionnaires and checklist forms were used to collect information. Operations were carried out either by antegrade or retrograde SIGN nail. Post operatively control radiographs, the lower limb length and mal-rotation deformities were assessed.Results: Comminuted femoral shaft fracture accounted for 20.3% of all adult femoral shaft fractures admitted at MOI. Deep wound infection occurred in 2.5%. Shortening of 2-3cm was seen in 3.8% of the patients. No patient had shortening of more than 3cm. External rotation deformity of more than 20 degrees occurred in 6.3% of the cases. Internal rotation deformity of more than 15 degrees was seen in 7.9%. Knee flexion of less than 90 degree was encountered in 7.5% of patients. By 18th week 95% of the patients had callus formation. Conclusion: SIGN nail appears to be an effective treatment for comminuted femoral shaft fractures in settings where image intensifiers and fracture tables are not readily available. They have excellent to good outcomes in rate of callus formation, limb length and limb alignment outcomes.
