Effect of inductor types and shapes on the characteristics of an inorganic EL driven by wireless power transfer
Authors: Sato Daiki , Kitawaki Taisei , Wani Koichi , Yamamoto Shin-ichi 
Published: April 2022

Abstract
A wireless power transfer (WPT) circuit was developed for an inorganic electro-luminescent (EL) device. When transmission and receiver circuits are both in resonant mode, low operating voltage of 30 V was enough to achieve the EL luminance as high as 180 cd m−2. As for the transmission and the receiver coils, different types and shapes are studied to clarify those effects on the EL luminance and transmission efficiency. Solenoid coils generally presented higher luminance than other types. Polygonal solenoid coils resulted in even higher luminance and transmission efficiency than circular solenoids. A spiral or a spider coil, in which air core area is much smaller than the solenoid coil, was found to be less sensitive to coil displacement. The difference in EL performances with the variation of coils suggests the possibility of further improvement the WPT system.
Satisfaction of the producers and orange production trends in the main Brazilian citrus belt
Authors: Guerreiro Neto Gerônimo , Fernandes Figueira Sérgio Rangel 
Published: April 2022

O objetivo deste trabalho foi avaliar a satisfação dos produtores quanto ao cultivo da laranja-doce (Citrus sinensis) e as tendências da produção, no principal cinturão citrícola brasileiro – nos estados de São Paulo e Minas Gerais (Triângulo Mineiro / sudoeste de Minas Gerais). Foram entrevistados 260 produtores de 922 propriedades estratificadas [até 20.000 árvores (pequenas), de 20.001 a 100.000 (médias), e mais de 100.000 árvores (grandes)]. A análise com 93% de nível de confiança e 5% de erro amostral mostrou que 92% das propriedades são próprias, 28% são irrigadas, 61% têm menos de 20 mil árvores, e 81% são cultivadas há mais de 20 anos; além disso, 45% dos produtores desejam plantar a cultivar ‘Pera Rio’, e 53% dos produtores desejam utilizar o portaenxerto citrumelo ‘Swingle’. As regiões preferidas para plantio são Avaré, Triângulo Mineiro e São José do Rio Preto. Os maiores receios quanto à produção de laranja no cinturão citrícola são os fatores climáticos adversos, em seus setores norte e noroeste, e os problemas fitossanitários em seus setores sudoeste, sul e centro. Apesar da redução do número de propriedades com laranja nas últimas décadas, essa tendência pode ser atenuada pela satisfação com a cultura principalmente da parte dos maiores produtores. Isso pode ser confirmado pela decisão de estabelecer novos plantios em 69% (grandes), 48% (médias) e 36% (pequenas) das propriedades.

Published: April 2022

O objetivo deste estudo foi fazer um reconhecimento dos saberes etnobotânicos das comunidades tradicionais de plantas alimentícias não convencionais (Panc), bem como uma caracterização de seus compostos bioativos, para garantir a segurança nutricional e a segurança alimentar. As análises foram feitas para determinar os compostos fenólicos, carotenoides e atividade antioxidante das diferentes espécies de Panc encontradas nas Unidades de Produção Familiar (UPF), das famílias participantes da Associação Escola Família Agrícola da Região Sul (Aefasul). Os resultados da pesquisa indicaram que 62% das famílias entrevistadas já tinham ouvido falar sobre Pancs e, entre as indicações, 355 foram apontadas como sendo eventualmente consumidas pelas famílias entrevistadas, dentre as quais se destacaram as espécies: Ananas bracteatus, Butia odorata, Eugenia uniflora, Psidium cattleianum e Syagrus romanzoffiana. Em relação aos compostos bioativos encontrados, destaca-se o teor de carotenoides, com 119.840 μg β-caroteno g-1 nas folhas de Tropaeolum majus, e os teores de compostos fenólicos, com equivalente em ácido gálico (EAG) de 186,02 g 100 g-1 em suas flores. Os compostos bioativos encontrados nas Pancs levam-nos a inferir elas apresentam grande potencial nutricional e econômico. Todavia, são necessárias mais pesquisas, assim como diferentes métodos de análise, para confirmar resultados e fornecer maior evidência científica sobre essas propriedades e garantir a segurança nutricional e alimentar.

Hal ini dilakukan agar fokus sasaran kewilayahan dan sinergitas program pembangunan infrastruktur dapat tercapai.Â Â
A BL Lacertae Object at a Cosmic Age of 800 Myr
Authors: Koptelova Ekaterina , Hwang Chorng-Yuan 
Published: April 2022

Abstract
We report the discovery of the BL Lacertae object FIRST J233153.20+112952.11 at redshift >6 using near-infrared spectroscopy and broadband observations in the infrared, submillimeter, and radio wavelengths. The detection of the continuum break at ∼0.92 μm in the near-infrared spectrum of FIRST J233153.20+112952.11 provides an approximate redshift of 6.57, corresponding to an age of the universe of ∼800 Myr. The rest-frame UV/optical spectrum of FIRST J233153.20+112952.11 shows no emission lines detected with equivalent width >1.5 Å. The nondetection of the C iv
λ1549 broad emission line constrains the luminosity of the accretion disk to be ≲1045 erg s−1, which corresponds to the radiatively inefficient accretion regime of BL Lacertae objects. The spectral index of the rest-frame UV/optical continuum, α

ν,opt = 1.43 ± 0.23, is consistent with the expected spectral index of the synchrotron emission spectrum of the relativistic jet. The flat radio continuum (α

ν,r
≈ 0) in a rest-frame frequency interval of 7–23 GHz is similar to that of the typical BL Lacertae objects and also consistent with originating from the synchrotron jet emission. The rest-frame UV/optical and radio fluxes of FIRST J233153.20+112952.11 show significant (15%–40%) variations. The shortest recorded rest-frame timescale of these variations is ∼8 days. Assuming the local scaling relation between the radio luminosity and black hole mass, the 5 GHz radio luminosity of FIRST J233153.20+112952.11, 1.6 × 1033 erg s−1 Hz−1, suggests a billion solar mass central supermassive black hole.
Inrêvable et néo-contenant narratif en thérapie familiale
Authors: Benghozi Pierre 
Published: April 2022

Dans la clinique psychanalytique des « pathologies de contenant généalogique », le processus narratif en thérapie familiale psychanalytique permet l’émergence d’un néocontenant narratif. Dans cet article, l’auteur part d’une séquence de thérapie familiale psychanalytique pour présenter les notions de remaillage narratif des contenants familiaux effractés. Le néo-contenant narratif a une fonction thérapeutique d’étayage et de reprise du contenant généalogique démaillé, troué ou déchiré. C’est l’expression, au niveau topique du préconscient groupal, d’une corêverie groupale famille-thérapeutes. Cette approche témoigne d’une créativité alternative par rapport à la clinique du refoulement et de l’interprétation. Elle suppose une nouvelle posture psychanalytique, celle de l’accueil et de l’étayage. L’auteur l’illustre avec un exemple mobilisant un objet médiateur narratif.
Ariès : entre histoire, philosophie sociale et connaissance ordinaire des enfants
Authors: Garnier Pascale 
Published: April 2022

L’ouvrage d’Ariès, L’enfant et la vie familiale sous l’ancien régime , a ouvert un nouveau champ de recherche dans le domaine des sciences sociales, emportant un large succès public, en même temps que sa thèse d’une « découverte de l’enfance » suscitait de nombreuses critiques scientifiques. L’objectif de cet article est d’analyser un vaste corpus de ces critiques pour comprendre les opérations historiographiques mises en jeu par l’historien afin de donner une histoire à l’enfance. Nous en soulignons ici deux principales dimensions, d’une part, l’importance d’une philosophie sociale privilégiant un ordre domestique qui favorisait un mélange des âges ; d’autre part, la construction de l’enfance comme un ensemble d’attributs différenciés de ceux impartis aux adultes, à partir d’une connaissance ordinaire, de sens commun, des enfants. L’analyse ouvre ainsi une perspective heuristique pour comprendre les tensions qui traversent aujourd’hui les classements d’âge.
La parentalité pendant les années d’école maternelle : le point de vue de mères et de pères de CSP+ en REP
Authors: Picart Anne-Gaëlle , Bergonnier-Dupuy Geneviève 
Published: April 2022

Cet article rend compte d’une recherche visant à éclairer ce qui se joue en termes de parentalité à l’entrée de l’enfant dans l’univers scolaire. 34 entretiens ont été effectués auprès de mères et de pères, majoritairement de CSP+, dont les enfants fréquentent une école maternelle publique dans un quartier parisien situé en réseau d’éducation prioritaire (REP). Les résultats montrent que, si tou·te·s sont engagé·e·s dans une course au temps quotidienne, appliquant un planning « au cordeau », ce sont surtout les femmes qui organisent la vie familiale. Concernant l’école, les mères paraissent focalisées sur l’expérience actuelle de l’enfant tandis que les pères anticipent avec appréhension son passage au collège, dès l’école maternelle. Enfin, les femmes, plus encore que les hommes, témoignent d’une parentalité réflexive, basée sur la compréhension de soi et de l’enfant et engageant la responsabilité personnelle.
Les contributions de la Chine au financement et à la réalisation des infrastructures en Afrique
Authors: Aurégan Xavier 
Published: April 2022

En Afrique, si les besoins en infrastructures sont incommensurables, les besoins en financement le sont tout autant. Parmi les principaux bailleurs de fonds, la Chine et ses acteurs ont la particularité de pouvoir construire en Afrique l'infrastructure qu'ils financent. Cet article explore plusieurs sources statistiques nationales, régionales et internationales pour évaluer la contribution des acteurs chinois au financement et à la réalisation des infrastructures africaines. Notre étude démontre qu’ils interviennent principalement par le biais des prestations de services, que leurs interventions ne sont pas différentes de celles des autres et qu’elles sont majoritairement orientées vers les transports en Afrique de l'Ouest. Dans ce contexte, la Chine et ses représentants reproduisent-ils un modèle de développement inégal ? Classification JEL : F5, N4, N73, O1
L’accès aux produits financiers formels et le genre en Afrique de l’Ouest : quels sont les facteurs discriminants ?
Authors: Loaba Salamata 
Published: April 2022

Cet article identifie les facteurs socio-économiques qui expliquent la différence d’accès aux produits financiers formels entre hommes et femmes. Un modèle probit et la méthode de décomposition d’Oaxaca-Blinder sont utilisés sur un échantillon de 6 392 observations de la base de données Findex (2017). Les résultats indiquent une différence d’accès à un compte, expliquée (82 % pour le compte formel, 70,9 % pour le compte mobile money ) par le plus faible niveau d’études des femmes par rapport à celui des hommes, leur faible participation au marché du travail, leur faible niveau de revenu et leur accès limité au téléphone mobile.

Accès à l’électricité et déforestation dans les pays en développement
Authors: Bakehe Novice Patrick 
Published: April 2022

Cet article s’intéresse à l’effet de l’accès à l’électricité sur la déforestation à partir d’un échantillon de 87 pays en développement pour la période 1990- 2015. Nos résultats montrent que l’amélioration de l’accès à l’électricité réduit le taux de déforestation. Toutefois, en divisant l’échantillon en trois groupes de pays, nous trouvons qu’il n’y a pas d’impact significatif de l’accès à l’électricité sur la déforestation en Afrique subsaharienne. Ce dernier résultat peut être expliqué soit par le prix de l’électricité qui ne permet pas aux populations de gravir l’« échelle énergétique », soit par l’effet-rebond qui rend l’activité agricole plus attrayante.

Dramatique personnelle de la quête d’immédiateté de Dieu
Authors: Nussbaumer Jacques 
Published: April 2022

Analyser la question de l’immédiateté de Dieu en regard avec le développement du fondamentalisme permet de clarifier les modalités de cette « immédiateté », mais aussi d’interroger les institutions ecclésiales et académiques sur leur capacité à en rendre compte d’une manière qui réponde aux besoins vitaux de la foi. Partant de la quête contemporaine d’immédiateté de Dieu, cet article explore les ressources de l’approche dramatique et de la grammaire trinitaire tant pour exposer les impasses de certaines quêtes spirituelles que pour ouvrir un chemin d’intelligibilité propre à l’existence chrétienne.
Topography-Guided FS-LASIK With PAE Algorithm and Sirius Tomography Data for Correction of Myopia and Myopic Astigmatism
Authors: Yuan Yifei , Zhang Yu , Sun Tong , Sun Xiaoxiao , Zhao Xiaorui , Chen Yueguo 
Published: April 2022

PURPOSE:
To compare the clinical outcomes after topography-guided and femtosecond laser–assisted laser in situ keratomileusis (FS-LASIK) planned with the Phorcides Analytic Engine (PAE) algorithm system and Sirius tomography data for correction of myopia and myopic astigmatism when the ocular residual astigmatism (ORA) was great or not.

METHODS:
In this retrospective study, a total of 163 eyes with myopia and myopic astigmatism (99 patients) were included. Eyes with myopic astigmatism and high ORA of 0.75 diopters (D) or greater were assigned to the high ORA group and the others to the low ORA group. All surgeries were performed by topography-guided FS-LASIK planned with a PAE algorithm system. PAE took anterior and posterior corneal negative cylinder of the 5-mm zone from the Sirius combined topography and tomography. Refractive and visual outcomes, vector analysis, and corneal aberrations were compared between the two groups.

RESULTS:

At 6 months postoperatively, the uncorrected distance visual acuity of 20/16 or better was measured in 59% of eyes in the high ORA group and 66% of eyes in the low ORA group (
P
= .307). Postoperative corrected distance visual acuity, manifest refractive spherical equivalent, refractive astigmatism, target induced astigmatism, surgically induced astigmatism, and difference vector were similar between the two groups (
P
> .05). The postoperative corneal astigmatism was significantly higher in the high ORA group (
P
= .008), and the high ORA group over-corrected astigmatism with the rule and showed a higher correction index (
P
= .003) compared with the low ORA group.

CONCLUSIONS:
Topography-guided FS-LASIK with PAE algorithm and Sirius combined topography and tomography data for correction of myopia and myopic astigmatism achieved the predicted surgical outcomes and there was a tendency to have a similar clinical outcome for PAE when the ORA was great or not. However, the PAE with high ORA overcorrected astigmatism with-the-rule and showed a higher correction index compared with the low ORA group.

Management of Anterior Stromal Necrosis After Polymethylmethacrylate ICRS: Explantation Versus Exchange With Corneal Allogenic Intrastromal Ring Segments
Authors: Kozhaya Karim , Mehanna Carl Joe , Jacob Soosan , Saad Alain , Jabbur Nada S. , Awwad Shady T. 
Published: April 2022

PURPOSE:
To evaluate management of keratoconic eyes with anterior stromal necrosis overlying the intracorneal ring segment (ICRS), by either ICRS explantation alone or exchange with corneal allogenic intrastromal ring segments (CAIRS).

METHODS:
Among 643 Intacs SK (Additional Technology, Inc) inserted at one institutional center, 16 eyes (15 patients) with overlying spontaneous anterior stromal necrosis were identified. Data included size of stromal defect and refractive and topographical findings before ICRS insertion, before anterior stromal necrosis, and 6 months after intervention.

RESULTS:

The 10-year incidence of anterior stromal necrosis after femtosecond laser–assisted ICRS insertion was 5.5%. Eight eyes underwent ICRS removal only and 8 eyes had ICRS exchanged with CAIRS. In the first group, CDVA worsened from 0.14 before melt to 0.28 logMAR after removal (
P
= .10), simulated keratometry (SimK) and maximum axial keratometry (Kmax) increased from 44.73 to 46.34 diopters (D) (
P
= .14) and from 49.23 to 52.26 D (
P
= .14), respectively, and coma worsened from 0.87 to 1.52 D (
P
= .02). In the CAIRS group, CDVA of 0.16 before melt improved to 0.11 logMAR postoperatively (
P
> .99), and topographic indices stabilized with SimK, Kmax, and coma mildly altering from 45.31 to 45.44 D (
P
> .99), from 49.25 to 49.64 D (
P
> .99) and from 0.87 to 0.81 D (
P
> .99), respectively. Whether the ICRS were explanted or exchanged, the visual and topographic mean values were better than those reported before ICRS implantation, whereas higher order aberrations in eyes without CAIRS regressed to levels before ICRS insertion. At the site of melt, thinnest residual stromal thickness averaged 327 µm with ICRS removal and 490 µm with CAIRS. Eyes with larger melt areas resulted in less optimal results with CAIRS implantation.

CONCLUSIONS:
Early experience in the management of anterior stromal necrosis by exchange of polymethylmethacrylate ICRS with CAIRS seems to avoid stromal thinning and confer better visual and topographic results, which were more pronounced with thicker segments. The benefit of CAIRS in large stromal melts needs to be investigated.
