Authors: Guarnizo-Franco Anderson , Martínez-Yepes Pedro Nel
Published: September 2021

La hidrólisis ácida es un método de pretratamiento que ha sido empleado para aumentar la accesibilidad de la biomasa frente a un ataque enzimático en los procesos que conllevan a la obtención etanol. Por tal motivo, el efecto de hidrólisis ácida sobre la biomasa lignocelulósica del raquis de banano Cavendish Valery fue investigado. Usando el parámetro de severidad combinada (CS), que involucra la variable temperatura, tiempo y pH, se observó como varió el contenido de materia seca, celulosa, holocelulosa, hemicelulosa, azúcares reductores y 5hidroximetilfurfural (HMF). Los resultados registran el momento en que se logra una mayor concentración de azúcares reductores y una producción despreciable de HMF cuando la CS es de 2,67 (170 ºC, 40 min y 1% de ácido sulfúrico). Además, en estas condiciones, el material muestra una avanzada degradación de hemicelulosa, mientras que no se evidenció el mismo efecto sobre la celulosa.

Published: September 2021

Remote sensing of solar-induced chlorophyll fluorescence (SIF) provides new possibilities to estimate terrestrial gross primary production (GPP). To mitigate the angular and canopy structural effects on original SIF observed by sensors (SIF
obs
), it is recommended to derive total canopy SIF emission (SIF
total
) of leaves within a canopy using canopy interception (

i

) and reflectance of vegetation (

R

V

). However, the effects of the uncertainties in

i

0

and

R

V

on the estimation of SIF
total
have not been well understood. Here, we evaluated such effects on the estimation of GPP using the Soil-Canopy-Observation of Photosynthesis and the Energy balance (SCOPE) model. The SCOPE simulations showed that the

R

between GPP and SIF
total
was clearly higher than that between GPP and SIF
obs
and the differences in

R

(

Δ

R

) tend to decrease with the increasing levels of uncertainties in

i

and

R

. The resultant

Δ

R

decreased to zero when the uncertainty level in

i

0

and

R

V

was ~30% for red band SIF (RSIF, 683 nm) and ~20% for far-red band SIF (FRSIF, 740 nm). In addition, as compared to the TROPOspheric Monitoring Instrument (TROPOMI) SIF
obs
at both red and far-red bands, SIF
total
derived using any combination of

i

0

(from MCD15, VNP15, and CGLS LAI products) and

R

V

(from MCD34, MCD19, and VNP43 BRDF products) showed comparable improvements in estimating GPP. With this study, we suggest a way to advance our understanding in the estimation of a more physiological relevant SIF datasets (SIF

Authors: Tuoyo Diamond O. , Opone Festus C. , Ekhosuehi N.
Published: September 2021

This paper presents a new generalization of the Topp-Leone distribution called the Topp-Leone Weibull Distribution (TLWD). Some of the mathematical properties of the proposed distribution are derived, and the maximum likelihood estimation method is adopted in estimating the parameters of the proposed distribution. An application of the proposed distribution alongside with some well-known distributions belonging to the Topp-Leone generated family of distributions, to a real lifetime data set reveals that the proposed distribution exhibits more flexibility in modeling lifetime data based on some comparison criteria such as maximized log-likelihood, Akaike Information Criterion [AIC=2k-2 log⁡(L) ], Kolmogorov-Smirnov test statistic (K-S) and Anderson Darling test statistic (A*) and Crammer-Von Mises test statistic (W*).

GESTÃO DE ESTOQUE: REVISÃO DE LITERATURA DA UTILIZAÇÃO DA METODOLOGIA JUST IN TIME COMO DIFERENCIAL COMPETITIVO
Authors: da Cruz Sacramento Andressa
Published: September 2021

This paper presents a literature review of the use of the Just in Time methodology as a competitive differential in companies that seek to control and manage their stocks using this tool. The Just in Time philosophy has undergone several changes throughout its development process by Toyota Motor Company. The first concept was to increase profits. To do so would have to increase the selling price. Thinking about market competitiveness this reasoning would not hold for long and was soon rethought to something more logical and that could please customers in business. Coming to the conclusion that minimizing costs would increase profits. The first surveys pointed the direction from where to begin modifications in the production process, which would be in improving the flow. From this observation began the Just in Time production system that proposes: zero inventory, reduced process time, quality, production on demand, eliminate losses and defects, automate processes and identify standardized operations. The objective research goes through book searches referring to inventory management, materials management, production planning and control among others described in the references. Thus, the work studied the emergence and evolution of the Just in Time methodology and its evolution the advantages and disadvantages of implementation and the understanding of pull production
DESAFIOS DO TRANSPORTE DE GLP PARA O ESCOAMENTO DO POLO URUCU DURANTE A VAZANTE DA BACIA AMAZÔNICA
Authors: LUIZ DO CARMO JORGE , BRAGUEZ ARAGAO MARCIO
Published: September 2021

Urucu Pole is an oil complex located in a remote area of the Amazon rainforest. There are no pipelines to transport oil and liquefied petroleum gas (LPG) production to consumer markets. The LPG produced on site is transported by a fleet of specialized vessels. The navigability conditions of rivers are strongly influenced by the periods of annual flood and ebb. This paper analyzes the logistical challenges of waterway transport for the relief of LPG from the Urucu Pole during the drought in the North of the country and in the countries bordering the state of Amazonas, a period in which the water levels of the Amazon basin drop dramatically, greatly restricting the safe navigation in the region.

AUXÍLIO EMERGENCIAL - IMPACTOS NA RENDA E NO ICMS
Authors: Gevano Rios Ponte Antonio
Published: September 2021

The literature has shown that public policy programs based on social protection for the most needy, provide a reduction in income inequalities, as long as these policies bring neutrality to fiscal policy, that is, they do not increase the public deficit. The instruments of social protection, especially those of direct income transfer to the most needy, may result in an increase in consumption by the poorest classes, and consequently an improvement in tax revenue, especially in the collection of ICMS, consumption tax . So, we intend to show here that emergency aid, which is a temporary income transfer program implemented by the Federal Government to mitigate the impact of the economic crisis resulting from the COVID-19 pandemic, had direct implications for the economy; especially in improving the income of the most needy and a return, in part of the benefit, to the revenues of the States, in the form of taxation. Said Emergency Aid minimized the drop in collection, or even maintained the collection levels of ICMS, the most important tax of the States, which contributed to the revenue of these federated entities. As a result of the fiscal problems caused, Emergency Aid heated the economy and boosted consumption in order to keep the state ICMS tax collection at even higher levels, in many states, compared to the pre-pandemic period. The objective is to outline an empirical strategy to measure the impact that the emergency aid had on the collection of ICMS, that is, to measure the sensitivity of the variation of the ICMS of the States due to the injection of resources of this transfer program.
Análisis de costo efectividad de la educación de pacientes con diabetes tipo 2 por pares
Authors:   , González Lorena
Published: September 2021

En general, las metas de tratamiento en personas con DMT2 pocas veces se alcanzan y la calidad de atención no es la adecuada para prevenir el desarrollo de complicaciones, generando un gran impacto socioeconómico y un creciente problema de salud pública. La educación a través de pares con DM, complementaria al control y tratamiento de la enfermedad, es una alternativa a la estrategia tradicional de educación de personas con DMT2, para mejorar la calidad de atención y disminuir el impacto socioeconómico de la enfermedad. Esta estrategia logra resultados de efectividad no inferiores a la educación tradicional. Sin embargo, para que los decisores del sistema de salud adopten esta estrategia, es necesario demostrar no sólo su eficacia sino también su costo-efectividad. Lamentablemente, la evidencia actual de costo-efectividad de la educación a través de pares respecto de la educación tradicional, es escasa. El objetivo del trabajo se centró en evaluar la costo-efectividad de la educación de pacientes con DMT2 educados, durante un año, por un equipo profesional en salud (educación tradicional) versus educación y apoyo impartida por un par con DM (educación de pares). Se realizó un análisis de costo efectividad en base a un estudio clínico retrospectivo desarrollado en la ciudad de La Plata, sobre 199 personas con DMT2, organizados en 2 grupos, uno que recibió educación tradicional (ET) y otro que recibió educación a través de personas con DM (pares). Se consideró el cambio en HbA1c como el indicador primario de efectividad; y otros indicadores secundarios: glucemia en ayunas, IMC, PAS y PAD. Se estimó el costo directo de cada estrategia en base a los recursos utilizados en el estudio clínico, y se evaluaron tres escenarios de costos para la estrategia de educación de pares. Se realizó un análisis de sensibilidad univariado para evaluar la robustez de los resultados. Como resultados, en la estrategia educativa tradicional, el costo por unidad de % de HbA1c descendido fue de $2.621; en la estrategia de educación a través de pares fue de $1. 508, $1.779 y $2.071, para cada uno de los tres escenarios considerados E1, E2 y E3 respectivamente. Por cada $100 invertidos se logra descender 0,04% de HbA1c con la estrategia de educativa tradicional, y 0,07% en E1, 0,06% en E2 y 0,05% en E3. El análisis de sensibilidad univariado demostró que los resultados obtenidos son robustos. En el presente trabajo la estrategia educativa a personas con DMT2, complementaria al control y tratamiento de la enfermedad, a través de pares es costo efectiva respecto a la estrategia de educación tradicional.

Published: September 2021

El COVID-19, conocido popularmente como coronavirus, ha sido uno de los fenómenos mediáticos más relevantes desde principios de 2020. Uno de los efectos más notorios de su rápida expansión en España fue la cancelación del Mobile World Congress (MWC). Se trata de un foro global que reúne anualmente a las principales empresas tecnológicas del mundo y se define, en materia de agenda empresarial, como uno de los principales eventos anuales del sector. Según las estimaciones realizadas por la empresa organizadora GSMA, la previsión de asistentes al evento, previo a los resultados conocidos, era de más de 100.000 personas, contando tanto los asistentes de las empresas participantes como el público en general. Pese a ello, el pasado 12 de febrero y refiriéndose a las sucesivas cancelaciones de las empresas patrocinadoras y participantes por motivos de salud pública, la organización del MWC decidió cancelar el evento. Se analizan en este trabajo 125 noticias de los dos principales periódicos económicos en España y a través de una metodología basada en el análisis del contenido se comprueba el impacto del Congreso objeto de este estudio. En el periodo estudiado se concluye que las noticias sobre el Congreso Mundial de Móviles no fueron tan relevantes para estos medios de comunicación como sí lo fueron los efectos del covid-19.

PV solar energy is the upcoming king of the energy source in the world, which is the fastest growing, most available, sustainable, clean, and environmentally friendly renewable energy. The essential characteristic of PV solar energy is generating the maximum power at mid-day. At the same time, the energy demand is high during the daytime. Due to this, PV solar energy replaces the conventional energy demand at peak periods. The sun is the source of PV solar energy, and it changed into electricity directly by using solar cells, which are made from semiconductor materials called silicon. Therefore, PV solar energy plays a crucial role in providing usable energy, and as well as reducing carbon dioxide emissions. However, the solar energy generation systems not achieved the desired efficiency yet, because of many unsolved problems like weather conditions, losses, materials made by and so on. The aims of this paper is to review the current literature on the improvement of the PV solar energy generation system's overall performance. First, to figure out the existing challenges, like environmental factors and natural phenomena that affect the PV solar modules efficiency. Then it presents the techniques that are used to enhance the PV solar modules overall performance. Finally, to propose the best ways and techniques to improve the PV modules efficiency and suggest to further studies.

Published: September 2021

The study was conducted to identify superior D. edulis trees using phenotypic characters (fruit and seed size) as the criteria to select candidate trees for subsequent multiplication through vegetative propagation. Five D. edulis compound trees were randomly selected within Onne community in Eleme LGA Rivers state in a preliminary effort to assist households in the selection and multiplication of desirable tree phenotypes. Seeds were extracted by softening fruit with warm water at 57oC. Fruit and seed length (mm), breadth (mm), and thickness (mm) were taken using veneer caliper. Size of fruit and seed was calculated as: length × breadth × thickness. The experiment was a completely randomized design in its layout and data analysis was carried out using analysis of variance and regression after a normality test was conducted using Shapiro-Wilk. The results showed that highest mean fruit size (79.38 ± 3.99 mm) was recorded in tree 3 and the lowest was tree 5 (29.60 ± 1.48 mm): while, highest seed size (34.78 ± 2.47 mm) was recorded in tree 3 and the lowest in tree 4 (15.58 ± 0.99 mm). Highest within tree fruit size variability was recorded in tree 1 (24%) and the lowest in tree 4 (12%): while the highest within tree seed size variability was recorded in tree 2 (28%) and the lowest in tree 5 (15%). There was however a significant difference in fruit and seed size between the trees. Pairwise comparison showed that tree 1 was not significantly different from tree 2 in fruit and seed size. There was a significant positive correlation between fruit and seed size among the trees. This implies that selection for large fruit size automatically selects for large seeds size. Large fruited trees can therefore be multiplied from these trees using vegetative propagation.
Spectral Extremal Results for Hypergraphs
Authors: Hou Yuan , Chang An , Cooper Joshua
Published: September 2021

Let $F$ be a graph. A hypergraph is called Berge $F$ if it can be obtained by replacing each edge in $F$ by a hyperedge containing it. Given a family of graphs $\mathcal{F}$, we say that a hypergraph $H$ is Berge $\mathcal{F}$-free if for every $F \in \mathcal{F}$, the hypergraph $H$ does not contain a Berge $F$ as a subhypergraph. In this paper we investigate the connections between spectral radius of the adjacency tensor and structural properties of a linear hypergraph. In particular, we obtain a spectral version of Turán-type problems over linear $k$-uniform hypergraphs by using spectral methods, including a tight result on Berge $C_4$-free linear $3$-uniform hypergraphs.
Selection of efficient ships according to the criterion of marginal price at the feasibility study
Authors: Vasileva Oksana Y. , Nikulina Marina V. Nikulina , Platov Juri I. Platov
Published: September 2021

The article deals with the problem of selecting efficient ships by the feasibility study in which brake power, main dimensions, payload, speed and fuel consumption are determined. The necessity of using the proposed selection at the initial stage of the ship's design is justified; the problems that arise at the present time are denoted. The purpose of the article is to propose a criterion for the selection of efficient vessels, "tied" to the operating conditions, based on the marginal cost of the ship. A method for its determination is presented. At the same time, annual revenues and operating costs should be determined by modern methods of business planning for the operation of the fleet. When searching for the parameters of the ship, the optimal fuel consumption is determined. The rest of the costs can be found according to the coefficients "tied" to the fuel consumption and calculated on the basis of existing prototypes. The results of calculations by the proposed method are shown; its merits and opportunities for improvement are noted with the availability of relevant information. The conclusion is made about the convenience and applicability of the proposed option for selecting efficient ship for the feasibility study based on optimization methods for determining the parameters of vessels under conditions of a high level of use of information technologies.

In our study, it was aimed to create a new drug delivery system by loading the chemotherapeutic drugs into exosome vesicles. This system act as a Trojan horse to targeting GBM cancer. Exosomes were isolated from the T-98G cell line and characterized. Exosomes were encapsulated with Temozolomide. Then, the effectiveness of this new delivery system was evaluated by using MTT, LDH, TAC, TOS, GR.
MTT results show a dose-dependent decrease in the TMZ and Exolimer+TMZ groups. But this rate decreased significantly in the Exolimer+TMZ groups. The lowest viability was observed at the Exolimer+TMZ 800 ng/ml concentration. Our results in LDH, GR, TAS and TOS analyzes shows correlation with MTT.
Based on this study, we think that targeting the exosome to cancer by combining with special molecules and nanotechnology will bring a new perspective to cancer treatment.

We report the discovery of a new, chemically distinct population of relatively high-metallicity ([Fe/H] > −0.7) red giant stars with super-solar [N/Fe] (≳+0.75) identified within the bulge, disk, and halo of the Milky Way. This sample of stars was observed during the second phase of the Apache Point Observatory Galactic Evolution Experiment (APOGEE-2); the spectra of these stars are part of the seventeenth Data Release (DR 17) of the Sloan Digital Sky Survey. We hypothesize that this newly identified population was formed in a variety of progenitors, and is likely made up of either fully or partially destroyed metal-rich globular clusters, which we refer to as globular cluster debris (GCD), identified by their unusual photospheric nitrogen abundances. It is likely that some of the GCD stars were probable members of the Gaia–Enceladus–Sausage accretion event, along with clusters formed in situ.
Outward Migration of Super-Jupiters
Authors: Dempsey Adam M. , Muñoz Diego J. , Lithwick Yoram
Published: September 2021

Recent simulations show that giant planets of about 1 M
J migrate inward at a rate that differs from the type II prediction. Here we show that at higher masses, planets migrate outward. Our result differs from previous ones because of our longer simulation times, lower viscosity, and boundary conditions that allow the disk to reach a viscous steady state. We show that, for planets on circular orbits, the transition from inward to outward migration coincides with the known transition from circular to eccentric disks that occurs for planets more massive than a few Jupiters. In an eccentric disk, the torque on the outer disk weakens due to two effects: the planet launches weaker waves, and those waves travel further before damping. As a result, the torque on the inner disk dominates, and the planet pushes itself outward. Our results suggest that the many super-Jupiters observed by direct imaging at large distances from the star may have gotten there by outward migration.

Data returned from the Cassini–Huygens mission have strengthened Enceladus, a small icy moon of Saturn, as an important target in the search for life in our solar system. Information gathered from Cassini to support this includes the presence of a subsurface liquid water ocean, vapor plumes and ice grains emanating from its south polar region, and the detection of essential elements and organic material that could potentially support life. However, several outstanding questions remain regarding the connectivity of plume material to the ocean and the composition of the complex organic material. Herein we introduce Tiger, a mission concept developed during the 2020 Planetary Science Summer School at NASA’s Jet Propulsion Laboratory. Tiger is a flyby mission that would help further constrain the habitability of Enceladus through two science objectives: (1) determine whether Enceladus’s volatile inventory undergoes synthesis of complex organic species that are evidence for a habitable ocean, and (2) determine whether Enceladus’s plume material is supplied directly from the ocean or if it interfaces with other reservoirs within the ice shell. To address the science goals in a total of eight flybys, Tiger would carry a four-instrument payload, including a mass spectrometer, a single-band ice-penetrating radar, an ultraviolet imaging spectrograph, and an imaging camera. We discuss Tiger's instrument and mission architecture, as well as the trades and challenges associated with a habitability-focused New Frontiers–class flyby mission to Enceladus.
Matching Species Names Across Biodiversity Databases: Sources, tools, pitfalls and best practices for taxonomic harmonization
Authors: Grenié Matthias , Berti Emilio , Carvajal-Quintero Juan , Winter Marten , Sagouis Alban
Published: September 2021

The quantity and quality of ecological data have rapidly increased in the last decades, bringing ecology into the realm of big data. Frequently, multiple databases with different origins and data characteristics are combined to address new research questions. Taxonomic name harmonization, i.e., the process of standardizing taxon names according to common sources such as taxonomic databases (TD), is necessary to properly combine multiple databases using species names. In order to be able to develop proper data matching workflows, TDs and tools using them need to be clearly and comprehensively described. But this is rarely the case. Common problems users have to deal with are: poorly described taxonomic concepts behind biological databases, lack of information when TDs are actively updated, and details regarding where the primary source of taxonomic information comes from (e.g., secondary TDs taking information from primary TDs). In addition, software to access these TDs is not always advertised, partly redundant, or developed with incompatible standards, creating additional challenges for users. As a result, taxonomic name harmonization has become a major difficulty in ecological studies. Researchers face a jungle of primary and secondary TDs with a diversity of tools to access them and no clear workflow on how to practically proceed. As a consequence, it is hard for users to know which TD, tool and workflow will fit the task at hand and lead to the most robust results when combining different biological datasets.

Here, we present an overview of major TDs as well as an extensive review of R packages to access TDs, and to harmonize taxa names. We developed an R Shiny web application summarizing meta-data and linkages among TDs and R packages (Figs 1, 2), which users can explore to learn about general features of TDs and tools and how they are linked among one another. This is particularly helpful to assist users when deciding on the TDs and tools that best fit the tasks and data at hand and to develop more informed workflows for taxonomic name harmonization. Finally, from our review and using the Shiny app, we were able to provide general best practice principles to harmonize taxonomic names and avoid common pitfalls.

To our knowledge, this study represents the most exhaustive review of TDs and R tools for taxonomic name harmonization. Our intuitive Shiny app can help make practical decisions when harmonizing taxonomic names across multiple datasets. Finally, our proposed workflows, based on conservative guideline principles (e.g., making sure incompatible taxonomic hypotheses are not combined together), provide a hands-on approach for taxonomic harmonization, which focuses on the quality of the end results while maximizing the number of species correctly matched.

Liberté d’expression, humour de résistance et surmois féroces
Authors: Landa Eva
Published: September 2021

Ce texte essaye d’apporter une contribution psychanalytique à quelques questions sur la liberté d’expression et son enseignement à l’école, soulevées par l’assassinat du professeur Samuel Paty. Parmi les aspects examinés : le retournement victimaire de la censure religieuse en « sensibilités religieuses blessées » (Jeanne Favret-Saada) ; le fantasme de séduction à l’œuvre dans les rumeurs qui précèdent l’attentat ; les croyances animistes à propos du pouvoir des images ; la distinction entre l’humour raciste et l’humour de résistance ; le surmoi féroce, élément hors dessin et pourtant présence inquiétante.
Notre identification à Freud
Authors: Grinberg León
Published: September 2021

En tant qu’analystes, nous avons introjecté des images de nos analystes et superviseurs, ainsi que celle de Freud comme concepteur de l’analyse ; ces images nourrissent notre « fonction psychanalytique de la personnalité ». L’identification à Freud modèle cette fonction, implique une éthique de la science et de la vérité sur soi-même, une curiosité pour le psychisme, une capacité d’intuition, une créativité de la pensée. Les auteurs vraiment innovants, comme Klein ou Bion, témoignent d’une identification authentique, créative et mature à Freud, qu’il faut bien distinguer d’une soumission à la lettre et d’une pseudo-identification. Cette position implique un difficile travail d’élaboration, un renoncement à l’omnipotence de l’analyste, une acceptation de la douleur psychique, et non une acceptation dogmatique aveugle aux apports de Freud. L’auteur souligne, à l’instar de Freud puis de Bion, que l’ insight et la recherche de vérité sont essentiels dans ce processus de survie et de croissance psychique que l’analyse a pour visée.
De guerre en guerre, les temporalités anachroniques du travail de la mémoire
Authors: de la Genardière Claude
Published: September 2021

À l’occasion d’une recherche faite aux archives de l’armée de l’air concernant la carrière de son père militaire, Claude de la Genardière s’est trouvée confrontée à nouveau à l’anachronisme des processus psychiques mobilisés et à leur capacité à rééclairer après coup les fondements et la dynamique de l’engagement psychanalytique. Elle montre comment le choix d’en avoir rendu compte lors d’un séminaire rassemblant historiens et psychanalystes a déplacé le regard sur les enjeux politiques liés aux guerres, notamment à la guerre d’Algérie. C’était bien un acte politique de sa part que de s’y être risquée.
L’acceptabilité sociale au Québec : nouvel instrument normatif d’action publique
Authors: Simard Louis
Published: September 2021

Au cœur des débats et controverses concernant les politiques publiques environnementales et les grands projets d’infrastructure et d’aménagement, l’acceptabilité sociale (AS) s’est institutionnalisée au Québec au fil des ans, en lien direct avec les notions de participation publique et de développement durable. Condition de plus en plus nécessaire à l’action publique, l’AS peut être comprise comme un nouvel instrument de type normatif afin d’articuler démocratie participative et démocratie représentative et ayant de fortes implications tant en termes de justice procédurale que distributive. Dans cet article, nous souhaitons répondre à quatre questions afin de mieux comprendre et analyser l’AS pour l’action publique : 1) comment définir l’AS et l’aborder de manière théorique ? Il est proposé de conceptualiser la notion à la manière de travaux sur les instruments d’action publique ; 2) quelle trajectoire a-t-elle connu au fil du temps ? Nous y répondons à travers l’analyse du corpus des rapports du Bureau d’audiences publiques sur l’environnement (BAPE) ; 3) qu’en disent les acteurs ? Nous rendons compte des similitudes et des différences des témoignages des professionnels de la participation publique (PPP) et ; 4) quelle est la portée de cette nouvelle norme sur les projets et les décisions ? De premiers constats sont proposés sur la base de trois études de cas importants et récents. Ces quatre réponses permettent, sous différents angles, d’apporter un éclairage nouveau et porteur à partir de l’expérience québécoise en matière d’AS.
Les acteurs, les actrices et leur conception de l’EPS : une force dialectique
Authors: Renaud Jean-Nicolas , Gomet Doriane
Published: September 2021

L’historiographie de l’éducation physique s’est déployée depuis près de quatre décennies. Des méthodes aux incidences sur la formation, cette histoire de la discipline n’a cessé de mettre en jeu le travail des acteurs et actrices. Aussi, la place de celles et ceux qui influent sur la trajectoire l'EPS s’accroît et le jeu des concours n’a fait qu’augmenter l’attention portée aux personnages dans la dynamique globale. Une biographie devient heuristique au regard de l’évolution de l’impact de ses apports au sein de la discipline. Mais l’histoire même de l’individu est affectée par la réception de ses idées par la discipline. Au final, ce double jeu permet à un personnage de se transformer en personnalité. Ce préambule cherche donc à placer le travail de C. Vivier comme une grille de lecture pour appréhender l’ensemble des articles qui vont suivre dans les deux numéros spéciaux de la revue STAPS . Il s’ensuit l’étude de P.-A. Lebecq, Y. Morales, J. Saint-Martin et N. Bazoge sur Pierre Seurin. La fin du modèle médical s’inscrit également dans le travail de S. Laffage-Cosnier sur le Dr Fourestier. Ce premier numéro spécial s’achève avec le couple De Rette. La présentation du père de la République des Sports, sous la plume de C. Polycarpe et J.-J. Dupaux, montre la confrontation de Jacques De Rette aux inerties de son temps. Son épouse Suzanne, décryptée par Loïc Szerdahelyi, porte paradoxalement, et en écho, les habits de cette inertie. Une complexité de l’histoire de l’EPS se trouve ainsi captée en cinq articles et quatre personnages...
Le Dr Max Fourestier ou le chant du cygne de l’ère médicale en éducation physique scolaire
Authors: Laffage-Cosnier Sébastien
Published: September 2021

La place des médecins en éducation physique scolaire depuis la fin du XIX e  siècle est bien réelle. De nombreux universitaires ont déjà publié des travaux qui révèlent le rôle et l’influence de la médecine au sein de ce champ de l’éducation. Le Dr Max Fourestier fait sans aucun doute partie des derniers médecins qui marquent de leur empreinte la sphère de l’EPS. En 1950, Max Fourestier met en place le mi-temps pédagogique et sportif à l’école Gambetta de Vanves qui articule les activités intellectuelles le matin et les activités physiques l’après-midi. Ainsi, l’enjeu majeur de cette étude consiste à montrer que les innovations scolaires de Vanves ont, d’un côté, mis en valeur une riche imbrication des conceptions dynamique, quantitative et normative de la santé explicitées par Georges Canguilhem, mais de l’autre, ont paradoxalement participé à la mise à l’écart et à la diminution symbolique du rôle du médecin en EPS dans un contexte de profondes restructurations administratives. Au final, il s’agira de s’interroger sur la symbolique de cette chute qui semble aller de pair avec la fin de l’ère dite médicale de l’éducation physique scolaire.

A study on vector variational-like inequalities using convexificators and application to its bi-level form
Authors: Pany Gayatri , Mohapatra Ram N.
Published: September 2021

This paper deals with the weak versions of the vector variational-like inequalities, namely Stampacchia and Minty type under invexity in the framework of convexificators. The connection between both the problems along with the link to vector optimization problem are analyzed. An application to nonconvex mathematical programming has also been presented. Further, the bi-level version of these problems is formulated and a procedure to obtain the solution involving the auxiliary principle technique is described in detail. We have shown that the iterative algorithm with the help of which we get the approximate solution converges strongly to the exact solution of the problem.

The purpose of this study was to assess the overall survival of patients with HGG using a nomogram which combines the optimized radiomics with deep signatures extracted from 3D Magnetic Resonance Images (MRI) as well as clinical predictors. One training cohort of 168 HGG patients and one validation cohort of 42 HGG patients were enrolled in this study. From each patient's 3D MRI, 1284 radiomics features were extracted, and 8192 deep features were extracted via transfer learning. By using Least Absolute Shrinkage and Selection Operator (LASSO) regression to select features, the radiomics signatures and deep signatures were generated. The radiomics and deep features were then analyzed synthetically to generate a combined signature. Finally, the nomogram was developed by integrating the combined signature and clinical predictors. The radiomics and deep signatures were significantly associated with HGG patients' survival time. The signature derived from the synthesized radiomics and deep features showed a better prognostic performance than those from radiomics or deep features alone. The nomogram we developed takes the advantages of both radiomics and deep signatures, and also integrates the predictive ability of clinical indicators. The calibration curve shows our predicted survival time by the nomogram was very close to the actual time.
Improving the oxidative stability of breadsticks with ginkgo (Ginkgo biloba) and ginseng (Panax ginseng) dried extracts
Authors: Hammad K.S.M. , Morsy N.F.S. , Abd El-Salam E.A.
Published: September 2021

Recently, there has been a growing interest in the use of natural antioxidants instead of synthetic ones. The aim of this work was to determine the effect of ginkgo and ginseng dried extracts as natural antioxidants on the stability of lipids in breadsticks over 55 days of storage at room temperature compared to butylated hydroxytoluene. Ginkgo and ginseng dried extracts were incorporated individually into breadstick formulae at levels of 0.5 and 1% to enhance its oxidative stability in storage. The increases in peroxide, p-anisidine and Totox values in the oil phase of the samples during storage were monitored. The changes in hydroperoxide, trans fatty acid and aldehyde contents were investigated by Fourier transform infrared spectroscopy. The sensory analysis was performed to evaluate the perceptible changes occurring during storage. The results indicated that the oxidation of oil in breadstick samples can be retarded by enriching the breadstick formula with dried ginseng extract at a 1% level.
