Abstract
We use new Hubble Space Telescope (HST) images of nine Green Pea galaxies (GPGs) to study their resolved structure and color. The choice of filters, F555W and F850LP, together with the redshift of the galaxies (z ∼ 0.25), minimizes the contribution of the nebular [O iii] and Hα emission lines to the broadband images. While these galaxies are typically very blue in color, our analysis reveals that it is only the dominant stellar clusters that are blue. Each GPG does clearly show the presence of at least one bright and compact star-forming region, but these are invariably superimposed on a more extended and lower surface brightness emission. Moreover, the colors of the star-forming regions are on average bluer than those of the diffuse emission, reaching up to 0.6 magnitudes bluer. Assuming that the diffuse and compact components have constant and single-burst star formation histories, respectively, the observed colors imply that the diffuse components (possibly the host galaxy of the star formation episode) have, on average, old stellar ages (>1 Gyr), while the star clusters are younger than 500 Myr. While a redder stellar component is perhaps the most plausible explanation for these results, the limitations of our current data set lead us to examine possible alternative mechanisms, particularly recombination emission processes, which are unusually prominent in systems with such strong line emission. With the available data, however, it is not possible to distinguish between these two interpretations. A substantial presence of old stars would indicate that the mechanisms allowing large escape fractions in these local galaxies may be different from those at play during the reionization epoch.

Abstract
The first radial alignment between Parker Solar Probe and Solar Orbiter spacecraft is used to investigate the evolution of solar wind turbulence in the inner heliosphere. Assuming ballistic propagation, two 1.5 hr intervals are tentatively identified as providing measurements of the same plasma parcels traveling from 0.1 to 1 au. Using magnetic field measurements from both spacecraft, the properties of turbulence in the two intervals are assessed. Magnetic spectral density, flatness, and high-order moment scaling laws are calculated. The Hilbert–Huang transform is additionally used to mitigate short sample and poor stationarity effects. Results show that the plasma evolves from a highly Alfvénic, less-developed turbulence state near the Sun, to fully developed and intermittent turbulence at 1 au. These observations provide strong evidence for the radial evolution of solar wind turbulence.
L’écriture comme génétique et politique du quotidien : l’exemple du cahier de bord en éducation spécialisée
Authors: Contini Jean-Christophe 
Published: May 2021

Contrairement aux idées reçues qui circulent dans le sens commun, les éducateurs spécialisés utilisent de nombreux supports graphiques dans le cadre de leur pratique professionnelle. Ces écrits mineurs soutiennent la communication nécessaire au travail d’équipe dans le cadre de l’institution de la vie quotidienne et contribuent dans le même temps à la fabrication du quotidien institutionnel, favorisant de la sorte une réflexivité et une génétique de l’agir qui se caractérise par la mise en œuvre d’une authentique politique indigène, une gouvernementalité de soi et des autres produite en équipe. La singularité du micro-lien social que constitue ce quotidien justifie dès lors d’en étudier les écritures mineures et ordinaires, peu connues, difficiles d’accès et souvent délicates à lire.

Alors qu’ils font l’expérience de la difficile articu­lation entre travail et apprentissage, pourquoi et comment les aider à rédiger leur mémoire de fin d’études par un dispositif d’accompagnement psychosociologique ? Les réflexions ici proposées rendent compte des problèmes auxquels ces alternants ont affaire pour rédiger un mémoire mixte, à savoir un mémoire de recherche fondé sur le travail et l’enquête conduits dans l’organisation qui les emploie.
Les Lumières : hier, aujourd'hui, demain

Peut-on baser une analyse économique de la finance sur une présomption de rationalité des acteurs des marchés financiers ? La théorie de l’efficience des marchés a été un utile point de départ, mais elle doit être repensée pour mieux rendre compte des crises financières ou des déviations des prix des actifs par rapport à leur fondamentaux. Cette contribution passe en revue trois voies amendant cette vision et ayant fait l’objet de nombreuses recherches ces dernières décennies : les bulles financières (la surévaluation des actifs par rapport à leur valeur intrinsèque), la théorie de l’agence (distinguant rationalité individuelle et rationalité collective), et l’économie comportementale
Variété des excitations dans les groupes
Authors: Chapelier Jean-Bernard 
Published: May 2021

L’étude de l’excitation en fonction des âges montre un lien constant en excitation motrice et présence de remarques associatives (verbales ou imagées). Leurs rapports varient : à la latence, l’activité motrice domine et le thérapeute doit faire un effort pour ne s’intéresser qu’aux associations parallèles et intervenir à ce niveau ; à la préadolescence, le sujet est plus facile à traiter car il y a une alternance entre les deux principes (désorganisation-réorganisation) ; à l’adolescence, c’est l’aspect verbal des associations libres qui domine. Le psychothérapeute pris dans les associations groupales doit entendre ce qui est en jeu et non être pris dans le chaos de l’excitation.
« L’institution merveilleuse » comme traitement… de l’excitation d’un groupe d’enfants
Authors: Sanahuja Maria de la Almudena , Bernard Alexandra , Franquin Aude 
Published: May 2021

Notre expérience clinique au sein d’un foyer d’accueil et d’hébergement d’urgence nous a permis d’observer que le trauma des enfants accueillis laisse des traces bruyantes ou insidieuses au sein de l’habitat institutionnel. Ces enfants aux forces pulsionnelles destructrices attaquent autant le groupe des soignants que les murs de l’institution. En parallèle, le groupe de professionnels peut en venir à fonctionner en miroir de la population accueillie. Dans ce cadre, le phénomène groupal vient mettre en exergue un phénomène de co-excitation exacerbée, devenant très vite difficile à contenir. La souffrance des enfants qui devient par contamination aussi celle de l’institution, traduit un inconscient groupal en perte de contenance. Il amène le besoin urgent pour le clinicien de restaurer les contenants abîmés. La proposition de recours à un outil de médiation innovant dénommé « l’institution merveilleuse » pourrait ainsi intervenir comme une aide à la relance de la fonction thérapeutique.

Published: May 2021

Background One of the efforts made to return people with severe mental illness to the community is to prepare with sufficient skills so then they can return to a productive life. The purpose of this study was to develop a vocational social rehabilitation model to increase the independence of the instrumental activity of daily living (ADL) among people with severe mental illness. Design and methods The study was conducted in 2 stages. Phase 1 used an observational design with a cross sectional approach. It was conducted at the Menur Mental Hospital from March to July 2020. The population of this study were all people with severe mental illness with a psychotic degree scoring ≥30. The total sample was 100. The data was analyzed using the Partial Least Square. The second phase was carried out by compiling modules from strategic issues and conducting expert consultations. Results The results of phase 1 showed that the instrumental ADL independence was directly influenced by perceived behavior, memory phase, motivation phase, skills and intention. Additionally, it is indirectly influenced by socio-demography, mental illness severity, attitude towards behavior, subjective norm, perceived behavioral control, attention, retention, motor reproduction, motivation and skill. The results of the phase 2 carried out were used to compile modules based on the stages of vocational rehabilitation consisting of determining eligibility, preparatory counseling, implementing rehabilitation, evaluation and ongoing support. Conclusion The vocational social rehabilitation model is related to the independence of the Instrumental ADL among people with severe mental illness.

Background:
With acute obstruction due to rectal or recto-sigmoid cancer, the safety and success of deploying self-expandable metal stents has been controversial. The aim of this systematic review was to synthesize the existing evidence on the outcomes and complication rates of stent placement in these patients.

Methods:
We performed a literature search of PubMed by using appropriate keywords, and manual reference screening of included articles was done. The article screening, data extraction, and quality assessment was done by four independent reviewers. A meta analyses was performed for the main outcome measures: technical and clinical success and complication rates.

Results:
We identified 962 articles in the search. After applying inclusion and exclusion criteria, we included 32 articles in the meta-analysis. The pooled technical success rate across 26 studies that reported it was 97% [95% confidence interval (CI): 95%-99%] without evidence of significant heterogeneity (I
2= 0.0%, P = 0.84), and the clinical success rate across 26 studies that reported it was 69% (95% CI: 58%-79%) with evidence of significant heterogeneity (I
2= 81.7%, P < 0.001). The pooled overall complication rate across the 32 studies was 28% (95% CI: 20%-37%) with evidence of significant heterogeneity (I
2= 79.3%, P < 0.001).

Conclusion:
The use of rectal stents in obstructing rectal or recto-sigmoid tumors seems to be technically feasible. A high rate of technical success, however, does not always translate into clinical success. A considerable complication rate is associated with this approach. Randomized controlled trials are needed to compare the outcomes of rectal stent placement with those of surgery.

Published: May 2021

Background:
Modified radical mastoidectomy is the mainstay in the treatment of a case of unsafe CSOM. In order to reduce the side effects of an open matoid cavity, many methods to obliterate the cavity have been devised.

Aims & Objectives:
Cavity obliteration was done to study the efficacy of mastoid cavity obliteration

Material and Methods:
We carried out cavity obliteration with hydroxyapatite in 20 patients and compared the results with non obliteration. Results: We observed that in addition to reduction in size of cavity, there is better epithelisation and hence faster healing of the mastoid cavity. There is also a significant improvement in hearing status of the patients.

Conclusion:
Modified Radical Mastoidectomy followed by cavity obliteration with hydroxyapatite granules has numerous advantages compared to leaving the cavity as such.

Published: May 2021

The study assessed the histological changes in the structure of gills and liver of juvenile Heterobranchus longifilis after exposure to varying sub-lethal concentrations of Dichlorvos. The fish, 120specimenswith mean weight of 47.33±2.31g and total length 10.67±0.58cm were selected and used for the experiment. Test fish were treated with concentrations of 0.00, 0.01, 0.015 and 0.02mg/l of Dichlorvos representing treatments T1, T2, T3 and T4 respectively. The study was carried out in a static renewal bioassay system. Fish samples were stocked in plastic bowls of 75litre capacity and the exposure period was7 days. All analyses were done using standard methods. The results showed prominent changes in the gills which included: partial epithelia lifting, hyperplasia, heavy degeneration changes, oedema, congestions and vacuolization. Changes in the liver included: congestion with sub-massive necrosis, liver parenchymal cell prominent with fatty/glycogen degeneration, hepatocytes and enlargement of portal tract. Histopathological changes on the two tissues increased with concentration of dichlorvos with severe damages observed at higher concentrations. This study showed that the use of dichlorvos as pesticides, which often find their way into the aquatic system, may have negative effects on fish. Thus, the use of organic pesticides should be encouraged.

Published: May 2021

The study investigated effects of graded levels of garlic (Allium sativum) powder supplemented diets on the growth performance of Clarias gariepinus juveniles. Five treatments comprising of twelve C. gariepinus juveniles of mean weight 7.52±0.00g per treatment were used in the study. Fish in each treatment was fed twice daily with experimental diets formulated with different inclusion levels of garlic powder at 0%, 1%, 2%, 3% and 4%; designated as control, T1, T2, T3 and T4 respectively. Fish were fed at 5% of their body weight and feeding trial lasted for 56 days. Analysis of the physico-chemical parameters of culture water was also carried out. Collected data were analysed and results showed that water temperature ranged from 27.0 to 28.5oC, pH ranged between 7.58 and 7.79, dissolved oxygen levels varied from 6.20 to 6.50mg/l, while ammonia content was observed to be between 2.33 and 2.73mg/l. Fish fed 3% garlic inclusion diet had the highest mean weight gain (MWG) of 40.63±30.04g, percentage weight gain (PWG) of 541.73% and specific growth rate (SGR) of 2.79±0.00%/day when compared with those on other treatments. The least PWG (345.25%) and SGR (1.95±0.00) were observed in the control and fish fed 1% garlic inclusion diets. However, MWG values were similar (p > 0.05) in T1 and T4. Fish fed diets with 2% garlic inclusion had the highest FCR (3.22±0.04) while the least value (2.29±0.03) was observed in T3. Results of the crude protein contents of treated fish carcass increased in all dietary treatments. Inference from this study indicated that incorporation of garlic meal in fish diets at 3% inclusion level improved growth performance and proximate composition of C. gariepinus juveniles.

The Probiotics, Lactobacillus Acidophilus and Saccharomyces cerevisiae in Diets of Clarias gariepinus Improve Feed Utilization and Growth
Authors: Enyidi U.D 
Published: May 2021

The study evaluated effects of incorporating different proportions of probiotics, Lactobacillus acidophilus (LAC) and Saccharomyces cerevisiae (SAC) in diets of Clarias gariepinus for improved growth and feed utilization. Six isonitrogenous (34% protein) diets were compounded with varying probiotic inclusion ratios (LAC: SAC) as followed: F1 (0:25%); F2 (25:0%); F3 (15:10%); F4 (10:15%); F5 (5:20%) and F6 (12.5:12.5%). The diets were mixed, preconditioned and steam pelleted at 100oC. Fish (average weight 35.16 ± 2.32g) were stocked at 15 fish per 80-liter aquarium tank and fed the experimental diets ad libitum for 60 days. Results showed that catfish fed with F2 (25% LAC and 0% SAC) had the best feed conversion ratio of 1.72±0.04, specific growth rate, 5.00±0.24 %/day, average weight gain 19.13±0.04g, final weight 56.46±0.08g and protein efficiency ratio of 0.59±0.02. Fish fed F1 (25% SAC and 0% LAC) achieved about half the growth and nutritional parameters of those fed diet F2. Growth performance increased with increasing inclusion level of LAC. However, fish fed F6 had a better specific growth rate than other mixtures except for those in F2 group. It could be inferred that reduced inclusion of SAC seemed beneficial to catfish.

Published: May 2021

The study was carried out to examine the influence of socio-economic characteristics on profitability of fish farmers in Owerri North LGA of Imo State. The study considered cost incurred and returns accrued on fish production in the area. Also, the relationship between the revenue derived from fish farming and various factors affecting fish production were determined. Standard procedures were adopted in all experimental analyses. One hundred and ten (110) fish farmers were randomly selected within the study area and used for the work, and data were collected using a well-structured questionnaire. Collected data were analysed using descriptive statistics such as percentages and inferential statistics (multiple regression at p<0.05) as well as cost and return analysis. Results showed that average annual income of a fish farmer was ₦6,269,886 while the profitability index was 1.89. Thus, indicating that, for every one-naira (₦1.00) investment made in fish farming in Owerri North LGA, ₦1.89 was returned to the farmer as net income. The study further showed that sex and years of farming experience were statistically significant and positively correlated (R2=0.8570; p<0.05) with net farm returns. On the other hand, age of the farmer, education attainment and marital status were negatively correlated and not significant. It is therefore recommended that people should engage in fish farming in the area as it is a profitable venture.

VOCALIZAÇÃO DA LATERAL PALATAL EM COMUNIDADES ARAPIRAQUENSES
Authors: Gomes dos Santos Ronaldo , Tenório Brunna de Oliveira , Santos Jeylla Salomé Barbosa dos 
Published: May 2021

Neste trabalho apresentaremos um fenômeno linguístico nomeada vocalização da lateral palatal, abordando como esta variação ocorre nos seguintes fatores sociais: sexo, idade e escolaridade, baseado em falantes de Arapiraca-AL, usando os áudios do banco de dados alagoano da Universidade Federal de Alagoas-UFAL, fundamentado nossa pesquisa em Labov, Tarallo, Mussalim e Bagno. Diante dessa análise foi possível perceber que o apagamento do som consonantal por um vocálico nesses casos não tem relação com escolaridade ou de sexo que se policia mais que o outro ao pronunciar as palavras que ocorre essa variação. Nosso objetivo assim como o da sociolinguística é corrigir o dito “errado” pela gramatica normativa, e estudar os motivos dessa variação. Pensando o porquê desse fenômeno ser comum em sociedades desfavorecida, porém pensando esse fenômeno sem preconceito já que pensamos em um lugar de fala onde a língua é livre, pois não falamos o que escrevemos, já que a emissão do som vocálico é mais fácil, por isso faz-se menos esforço para pronunciar palavras. O falante descarta as dificuldades na articulação do som, causando assim essa variação. Mas o português não-padrão é logico, bem estruturado e segue as tendências naturais da língua. Nesse caso o preconceito linguístico é desnecessário e irrelevante. Mostrando que a linguagem é um sistema de signos socializados, ou seja, seus elementos só adquirem significado quando inseridos em contextos de inter-relação, pois cada signo por si só não possui significado relevante. Quando se estuda e compreende esses conceitos, nosso ouvido fica mais sensível a língua falada, respeitando suas variações e seus falantes.
