Le pouvoir des jeunesses
Authors: Marmone Giordano 
Published: January 2020

Plutôt que de tenter de saisir les « jeunes » et la « jeunesse » au travers de catégories jugées universelles, il paraît plus fructueux d’examiner les productions locales des catégories d’âge. Chez les Samburu, pasteurs du Kenya septentrional où l’âge est à la base du classement des individus et d’une organisation sociopolitique égalitariste, la jeunesse est « inexistante » et la formation à l’autorité politique fait partie des compétences tôt inculquées, au même titre que les tâches économiques. C’est dans le cadre très particulier de l’apprentissage musical et des rivalités qu’il suscite pour tenir la position de soliste, que dans certains cas se dégagent les aptitudes au leadership. L’activité musicale, avec sa capacité à mettre en valeur les personnalités éminentes dès l’âge de l’incirconcision, occupe, dans ce parcours d’affirmation de pouvoir au niveau individuel, une place tout à fait centrale. Membre d’une société parfois qualifiée de « gérontocratique », le jeune samburu apparaît en réalité comme le protagoniste d’un processus autogéré de fabrication d’une autorité politique personnelle bien plus précoce qu’imaginé auparavant.
Un grin de jeunesse ?
Authors: Dessertine Anna 
Published: January 2020

À partir d’une étude ethnographique dans un village malinké au nord-est de la Guinée, cet article propose de poser la question de ce qui fait jeunesse en contexte rural ouest-africain. Il s’intéresse aux rassemblements de jeunes hommes autour d’un thé, les grins, pour montrer en quoi la jeunesse est avant tout relationnelle et qu’elle se déploie dans des pratiques spécifiques selon que les individus interagissent au sein d’une même classe d’âge (kari), avec des individus de génération différente, au village ou en migration, notamment dans les mines d’or artisanales de la région. Il s’agira d’analyser dans un premier temps les jeux statutaires qui se déroulent dans les grins et dans lesquels ces hommes rejouent quotidiennement les statuts d’aîné et de cadet dans des interactions entre individus qui se considèrent comme des pairs. Dans un second temps, ce travail s’intéressera aux relations induites par ces rassemblements, d’une part avec celles et ceux qui n’y participent pas, étant donné que ces réunions ont lieu à la vue de tous dans les cours centrales des résidences ; et, d’autre part, dans un contexte d’intensification des mobilités locales dans les mines d’or artisanales de la région.
Étudiants, sitters, nouchi et bakoroman

Dans un premier temps, cette contribution propose successivement le compte rendu de trois ethnographies portant sur des « jeunes », au Burkina Faso (Jacinthe Mozzocchetti, 2008, Être étudiant à Ouagadougou : itinérances, imaginaire et précarité), en Gambie (Paolo Gaibazzi, 2015, Bush bound : Young men and rural permanence in migrant West Africa) et en Côte d’Ivoire (Sasha Newell, 2012, The modernity bluff : Crime, consumption and citizenship in Côte d’Ivoire). Dans un second temps, un rapprochement comparatif est proposé entre ces trois ouvrages, visant à formuler quelques hypothèses sur les contours implicites de « la jeunesse » qui s’y dessinent. Décliné dans des thématiques récurrentes telles que la mobilisation politique, l’attente et la mobilité, il permet de faire apparaître que, loin de n’être qu’une question d’âge, la jeunesse se présente comme une catégorie implicitement masculine, qui n’est désignée comme telle que lorsqu’elle acquiert une certaine visibilité sociopolitique et une force de frappe oppositionnelle. Enfin, à partir des recherches de l’auteure auprès de jeunes vivant dans la rue au Burkina Faso — les bakoroman —, cet article se clôt sur le constat de l’intrusion récente de la catégorie « jeune » sur la scène politique burkinabè, au point qu’une retranscription dans la langue véhiculaire semble en train de s'imposer sous la graphie « zenna ».

AbstractEclosion times and rates ofRhagoletis tabellaria(Fitch) (Diptera: Tephritidae) and its parasitoid waspUtetes tabellariae(Fischer) (Hymenoptera: Braconidae) held at different chilling durations were determined in the laboratory. Adult fly and wasp longevity were also determined. Adult female and male flies fromR. tabellariapuparia chilled for 195 days at 4.8 °C and then held at 23.2 °C eclosed on average earlier thanU. tabellariaereared fromR. tabellariapuparia.Rhagoletis tabellariaalso eclosed significantly earlier from puparia chilled for 150 days than 120 days at 2.7 °C, butU. tabellariaeeclosion from the two treatments did not differ significantly.Rhagoletis tabellariaeclosion rates were greater with longer chill durations, butU. tabellariaeeclosion rates perR. tabellariapuparium did not differ among chill durations. NoR. tabellariaeclosed from nonchilled puparia held at 20–22 °C, but at least 18.8% of nonchilledU. tabellariaeeclosed. Female and maleR. tabellariaon average survived 52.1 and 83.3 days, respectively, while female and maleU. tabellariaesurvived 37.7 and 28.7 days, respectively. Results indicate diapause and developmental traits ofR. tabellariamay be more dependent on chilling durations and less flexible than those ofU. tabellariae, a wasp that appears adapted to flies in theR. tabellariaspecies complex.

Published: January 2020

As concepções formativas que subsidiam teoricamente o Estágio Supervisionado Curricular Obrigatório das licenciaturas de Educação Física têm constituído um polêmico campo de debate, sobretudo quando remetem à discussão da relação entre teoria e prática. Tendo como base a Teoria Crítica da Escola de Frankfurt, este artigo analisa o modo como a relação entre teoria e prática é discutida nas produções científicas da pós-graduação stricto sensu que tematizam o estágio. A crítica imanente e os princípios da dialética negativa de Theodor Adorno embasaram a análise dos dados e possibilitaram a compreensão das contradições existentes nas propostas conciliadoras entre teoria e prática, que prometem resolver os problemas da formação de professores e da parceria entre universidade e escola, sob o invólucro da criticidade.

Published: January 2020

Bonding technology namely as “sew free” technology is usually applied for joining the pieces of sportswear and leisure clothing. Influence of the thermal ageing duration on the peeling strength of woven fabric and knitted materials bonded at 150°C temperature for 10 s, 20 s, 30 s, and 40 s durations with two polyurethane films of 0.175 mm and 0.127 mm thicknesses has been investigated in this research. Based on the research results it was shown that the peeling strength of the textile bonds is dependent on material type and bonding duration, but it is not highly affected by the ageing at 45°C temperature for 150 min, 300 min, and 450 min. During concluding it may be stated that ageing at 45°C temperatures is not main factor influencing the bond quality during its exploitation in high temperature environment.

Published: January 2020

Nowadays, virtual try-on is an irreplaceable technology in fashion industry, so it is very important to prove virtual try-on matching with the real garments. Therefore, the aim of this research was to compare garment fit using virtual try-on and scanning technologies. For this reason, garment visual appearance and distance ease between straight fit dress and mannequin in respect to fabrics properties were investigated. Women mannequins in different sizes were scanned by 3D scanner VITUS Smart XXL without and with the real straight fit dresses made from five different woven fabrics. Fabrics mechanical properties were defined by KES-F. Scanned mannequins were covered with the same size and fabric virtual dresses by Modaris 3D (CAD Lectra). Distance ease of virtual and scanned garments was compared in bust and waist cross-sections. It was defined that distance ease values at bust girth of real and virtual dresses differed till 29.9 % (1.16 cm), while at waist varied from 7.3 % (0.51 cm) to 47.3 % (4.30 cm) because of wrinkles in this area. Generally, appearance of the virtual dresses was similar to real dresses with some differences in garment shape fluency, however by increasing of the mannequin size, similarities decreased. It was assumed that very high shear rigidity G could not be very well reflected in 3D CAD system, therefore differences between virtual and real dresses appearance occurred. The general appearance and form of bust and waist cross-sections of virtual dresses with fabric 03 had less similarities comparing with real dresses due to high G value. So, comparative study showed that the accuracy of virtual try-on was quite useful comparing to real garments, if shear rigidity of fabrics was lower than 1.6 N/m*º and tensile strain in warp direction was higher than 1.80 %.
Hydriding and Dehydriding Features of a Titanium-Added Magnesium Hydride Composite
Authors: CHOI Eunho , SONG Myoung Youp 
Published: January 2020

Magnesium has excellent hydrogen-storage properties except low hydriding and dehydriding rates. In the present work, titanium (Ti) was chosen as an additive to increase the hydriding rate of Mg and the dehydriding rate of MgH2. 15 wt.% Ti was added to MgH2 by milling in hydrogen (reactive mechanical grinding). The hydriding and dehydriding features of the Ti-added MgH2 composite (named 85 MgH2 + 15 Ti) were investigated. At the first cycle (n = 1), 85 MgH2 + 15 Ti absorbed 2.96 wt.% H for 2.5 min and 5.51 wt.% H for 60 min at 593 K in 12 bar H2, having an effective hydrogen-storage capacity of 5.51 wt.%. β-MgH2, γ-MgH2, TiH1.924, MgO, and MgTi2O4 were formed during reactive mechanical grinding. Reactive mechanical grinding of MgH2 with Ti is believed to create imperfections, produce cracks and clean surfaces, and decrease particle sizes. The phases formed during reactive mechanical grinding and their pulverization during reactive mechanical grinding are believed to make these effects stronger. Since the γ-MgH2 phase is believed to be decomposed at n = 1, the existence of the γ-MgH2 phase in the milled sample does not contribute to the improvement of the sorption behavior of Mg.

Published: January 2020

In the present research, the structural, the relative stable, and the electronic properties of AlnLin (n = 2 – 12) clusters were investigated by density functional theory (DFT). By comparing the calculated values of Al2 and Li2 dimers with experimental ones, the reliability of the proposed method was proved. Furthermore, by considering the values of average binding energy (Eb), vertical ionization potential (VIP), vertical electron affinity (VEA), fragmentation energy (△E), second-order energy difference (△2E), HOMO-LUMO (HL) gap, and chemical hardness (η) were calculated. It was found Fragmentation energy, second-order energy difference, VIP, VEA, the chemical stability and HOMO-LUMO gap exhibit odd-even oscillatory behaviours along with cluster size and have extreme values at n = 5 revealed Al5Li5 cluster yielded excellent stability. Those can be well explained by the density of states (DOS) that Li and Al atoms with stronger covalent bonds. Therefore, Al5Li5 cluster can be used as an ideal candidate for calculating Wilson parameters of Al-Li alloys.

The objective of this research was to study the effects of modified atmosphere, associated with masterpack transport packaging, and refrigerated storage time on the quality characteristics of pork loin cuts. Cuts of pork loin were packaged in trays, covered with poly(vinyl chloride) film. The trays were placed in a masterpack (MP), containing three gas compositions: A) 75% O2 : 25% CO2, B) 50% O2 : 50% CO2 or C) 100% CO2, and stored at 2 °C. Samples were taken after 1, 8, 15, and 22 days of storage, and evaluated for numerous shelf life traits. The development of Psychrotrophic aerobic bacteria and Pseudomonas spp. was found from the 15th day of storage. There was a significant treatment effect for some of the considered parameters, such as pH (P < 0.05) and color [L* (P < 0.07), a* (P < 0.07) and b* (P < 0.01)]. There was a significant interaction (P < 0.01) for the TBARS values. It can be concluded, from the microbiological point of view, that the use of modified atmospheres containing 25% to 100% CO2 promotes the conservation of meat for up to 15 days of storage under refrigeration. From the point of view of color, atmospheres containing 75% O2 : 25% CO2 and 50% O2 : 50% CO2 ensure the color of packaged pork meat when stored at 2 °C for up to 15 days. From the point of view of lipid oxidation, packages with 100% CO2 are recommended for storage periods of more than 15 days, whereas those with 75% O2 : 25% CO2 are recommended for storage periods of up to 8 days.
Physicochemical characterization of Gozitan Honey
Authors: Attard Everaldo , Mizzi Joseph 
Published: January 2020

Honey quality is clearly defined in the EU Directive 2001/110/EC, and by Codex Alimentarius (Codex Stan 12-1981) and the International Honey Commission (IHC, 2002). Our investigation aimed to characterize the physicochemical properties of honey produced on a small island, Gozo which is situated near Malta. Ten randomly collected honey samples were analysed for moisture content, pH, free acidity, water insoluble content, hydroxymethylfurfural (HMF) content and total phenolic compounds. Moisture content, pH, free acidity, water insoluble content, and HMF content were within the range specified in standards but the electrical conductivity was generally higher than 0.800 mS cm-1. This may be the result of the relatively high atmospheric and soil salinity on this small island. All the samples analysed were within the 40 mg kg-1 HMF limit, which is an indicator of honey quality. The total phenolic compounds, which represent some of the constituents derived from the nectar and pollen obtained during foraging, ranged between 236.555 and 294.209 GAE kg-1 honey. Principal Component Analysis showed the properties of polyfloral honey samples obtained from the southern part of the island to be different from those obtained from the northern part.

Background: Endometriosis is a gynecological disorder characterized by the presence of ectopic endometrium outside the uterus. It is a multi-factorial disease, where different processes facilitate the implantation and survival of ectopic endometrial tissue.
The Aim: This study aims to evaluate the levels of the expression patterns of mitogen-inducible gene 6 (Mig-6) in eutopic and ectopic endometrial tissues of endometriosis patients and their relevance to the levels of phosphorylated extracellular signal-regulated kinase 1/2 (pERK1/2) and redox status.
Methods: Relative gene expression levels of Mig-6 and the levels of pERK1/2 were assessed in endometrial tissues of control group and in both eutopic and ectopic endometrial tissues of endometriosis patients .Serum levels of total protein thiols and total protein carbonyls were also assessed in endometriosis and control groups.
Results: Relative gene expression levels of Mig- 6 showed significant lower values in endometriosis group as compared to control group, and they were associated with significant increase in pERK 1/2 levels and altered redox status.
Conclusion: These data, signified a significant role of downregulated Mig-6 expression, and activated ERK 1/2 signaling in the pathogenesis of endometriosis. Moreover, it suggested that oxidative stress indicated by high protein carbonyls level contributes to the pathogenesis of endometriosis and that protein thiols have a defensive role against oxidative stress.

The agricultural sector occupies an important economic and social position in Morocco. In this sense, in recent years our country has adopted a new strategy for the agricultural sector called the "Green Morocco Plan". This plan is based on two pillars, the first is that which provides agriculture with high added value, high productivity, and competitiveness, the second is that which offers solidarity-based agriculture, based on the fight against poverty, increasing the income of small farmers, particularly in disadvantaged areas (such as unfavourable stock areas, mountains or oases, plains and plateaus in semi-arid regions).
In our present study, we are particularly interested in the project to convert 760 ha of cereal crops into olive groves in the province of Tetouan. On the one hand, all stages of olive tree planting in cereal crops were monitored, as well as a comparison of yields, area, income, productivity and employment before and after the project was carried out. And on the other hand, an analysis of the various positive (social, economic and environmental) and negative (ecological) impacts of the project on the rural population in the province of Tetouan and on the environment in general. On the contrary, this project encountered several constraints, including natural, economic and social constraints.

Published: January 2020

Nigeria as a nation operates a federal structure of government, ‘Federalism’ refers to the existence in a country of more than one level of government, each with different expenditure responsibilities and taxing powers. The major aim of this work is to assess the impact of fiscal federalism and government expenditure on economic growth in Nigeria.
Secondary data employed in this work was collected from the Central Bank of Nigeria's (CBN) Statistical Bulletin, CBN Annual Report and Statement of Accounts, National Bureau of Statistics (NBS) and The World Bank Group for years 2000, 2017 and 2018 and part of 2019, respectively. The data covers the period, 1990-2017 on an annual basis. Ordinary Least Square (OLS) was used to estimate multiple regression model where Gross Domestic Product (GDP) as dependent variable and independent variables were interest rate, inflation rate, exchange rate, growth rate of share of federal government from the Federation account, growth rate of share of state government from the federal account, growth rate of share of local government from the Federation account. The results obtained from the regression shows that there exists a positive relationship between the economic growth and share of federal revenue, state government revenue, exchange rate and interest rate from the federation account and economic process in Nigeria. From the above result, it can, therefore, be concluded that a policy to maintain macroeconomic stability by controlling the rate of inflation within the reasonable limit is required to promote economic growth.
