The modern environment is characterized by a sharp increase in information flows that need to be processed in order to keep up with the development of science and education. Information flows are growing so fast that it is becoming increasingly difficult to process them using traditional methods. Simulator training, close to real conditions, meets the requirements of consolidating knowledge based on visual thinking and practicing decision-making skills in the operational management of the fleet. This allows you to consolidate knowledge and make optimal management decisions.

Such structures are stored in long-term memory and are easily reached if necessary, which contributes to the memorization of a large amount of information.

Many women spend a third of their lives in postmenopause, and it’s a given that sexual life must go on after menopause since its benefits were vastly proven. A number of factors influence sexuality in postmenopause: the age at which menopause sets in, how menopause sets in, physical and mental state, quality of sexual life in perimenopause and the quality and duration of the relationship with the partner. The hypoestrogenism that characterizes menopause leads to a decrease in libido, to changes in the genital apparatus (vaginal atrophy, dyspareunia) or other changes (hot flushes, impaired urination, depression), which negatively affect sexual health. Assessing sexual dysfunction is not easy. The interplay between the types of factors that predispose, precipitate and maintain sexual dysfunction requires preparation on the part of the clinician in identifying the elements of interest and indicating appropriate therapy. Research on the quantification of sexual dysfunction in women has led to the development of various scales or questionnaires to assess the impact of menopausal-related changes on sexual function and quality of intimate life. The ultimate goal of the clinician is to find an optimal method of treatment that will improve the condition and enhance the quality of sexual life. The available knowledge about menopausal sexuality may still be the tip of the iceberg in both medical practice and society and further research and information campaigns are greatly needed.
O contrato de seguro e a garantia de riscos decorrentes de caso fortuito, força maior e eventos imprevisíveis no direito brasileiro

Bridging the Gap: Categorizing Gravitational-wave Events at the Transition between Neutron Stars and Black Holes
Authors: Farah Amanda , Fishbach Maya , Essick Reed , Holz Daniel E. , Galaudage Shanika
Published: June 2022

We search for features in the mass distribution of detected compact binary coalescences which signify the transition between neutron stars (NSs) and black holes (BHs). We analyze all gravitational-wave (GW) detections by the LIGO Scientific Collaboration, the Virgo Collaboration, and the KAGRA Collaboration (LVK) made through the end of the first half of the third observing run, and find clear evidence for two different populations of compact objects based solely on GW data. We confidently (99.3%) find a steepening relative to a single power law describing NSs and low-mass BHs below

, which is consistent with many predictions for the maximum NS mass. We find suggestions of the purported lower mass gap between the most massive NSs and the least massive BHs, but are unable to conclusively resolve it with current data. If it exists, we find the lower mass gap’s edges to lie at

. We reexamine events that have been deemed “exceptional” by the LVK collaborations in the context of these features. We analyze GW190814 self-consistently in the context of the full population of compact binaries, finding support for its secondary to be either a NS or a lower mass gap object, consistent with previous claims. Our models are the first to accommodate this event, which is an outlier with respect to the binary BH population. We find that GW200105 and GW200115 probe the edges of, and may have components within, the lower mass gap. As future data improve global population models, the classification of these events will also improve.

Gamma-ray bursts (GRBs) are classified into long and short events. Long GRBs (LGRBs) are associated with the end states of very massive stars, while short GRBs (SGRBs) are linked to the merger of compact objects. GRB 200826A was a peculiar event, because by definition it was an SGRB, with a rest-frame duration of ∼0.5 s. However, this event was energetic and soft, which is consistent with LGRBs. The relatively low redshift (z = 0.7486) motivated a comprehensive, multiwavelength follow-up campaign to characterize its host, search for a possible associated supernova (SN), and thus understand the origin of this burst. To this aim we obtained a combination of deep near-infrared (NIR) and optical imaging together with spectroscopy. Our analysis reveals an optical and NIR bump in the light curve whose luminosity and evolution are in agreement with several SNe associated to LGRBs. Analysis of the prompt GRB shows that this event follows the E
p,i–E
iso relation found for LGRBs. The host galaxy is a low-mass star-forming galaxy, typical of LGRBs, but with one of the highest star formation rates, especially with respect to its mass (

These findings support theoretical predictions that events produced by collapsars can be as short as 0.5 s in the host frame and further confirm that duration alone is not an efficient discriminator for the progenitor class of a GRB.
Gaia May Detect Hundreds of Well-characterized Stellar Black Holes

Published: June 2022

Detection of black holes (BHs) with detached luminous companions (LCs) can be instrumental in connecting the BH properties with their progenitors since the latter can be inferred from the observable properties of the LC. Past studies showed the promise of Gaia astrometry in detecting BH–LC binaries. We build on these studies by (1) initializing the zero-age binary properties based on realistic, metallicity-dependent star formation history in the Milky Way (MW); (2) evolving these binaries to current epoch to generate realistic MW populations of BH–LC binaries; (3) distributing these binaries in the MW, preserving the complex age–metallicity-Galactic position correlations; (4) accounting for extinction and reddening using three-dimensional dust maps; and (5) examining the extended Gaia mission’s ability to resolve BH–LC binaries. We restrict ourselves to detached BH–LC binaries with orbital period P
orb ≤ 10 yr such that Gaia can observe at least one full orbit. We find that (1) the extended Gaia mission can astrometrically resolve ∼30–300 detached BH–LC binaries depending on our assumptions of supernova physics and astrometric detection threshold; (2) Gaia’s astrometry alone can indicate BH candidates for ∼10–100 BH–LC binaries by constraining the dark primary mass ≥3 M
⊙; and (3) distributions of observables, including orbital periods, eccentricities, and component masses, are sensitive to the adopted binary evolution model and hence can directly inform binary evolution models. Finally, we comment on the potential to further characterize these BH binaries through radial velocity measurements and observation of X-ray counterparts.

Here we present a detailed study of the broadband noise in the power density spectra of the black hole X-ray binary MAXI J1820+070 during the hard state of its 2018 outburst, using Hard X-ray Modulation Telescope observations. The broadband noise shows two main humps, which might separately correspond to variability from a variable disk and two Comptonization regions. We fitted the two humps with multiple Lorentzian functions and studied the energy-dependent properties of each component up to 90–150 keV and their evolution with spectral changes. The lowest-frequency component is considered as the subharmonic of the quasiperiodic oscillation component and shows a different energy dependence compared with other broadband noise components. We found that although the fractional rms of all the broadband noise components mainly decreases with the energy, their rms spectra are different in shape. Above ∼20–30 keV, the characteristic frequencies of these components increase sharply with the energy, meaning that the high-energy component is more variable on short timescales. Our results suggest that the hot inner flow in MAXI J1820+070 is likely to be inhomogeneous. We propose a geometry with a truncated accretion disk and two Comptonization regions.
Spectral-line Survey of the Region of Massive Star Formation W51e1/e2 in the 4 mm Wavelength Range

Published: June 2022

We present the results of a spectral-line survey of the W51e1/e2 star-forming region at 68–88 GHz. 79 molecules and their isotopologues were detected, from simple diatomic or triatomic molecules, such as SO, SiO, and CCH, to complex organic compounds, such as CH3OCH3 or CH3COCH3. A number of lines that are absent from the Lovas list of molecular lines observed in space were detected, and most of these were identified. A significant number of the detected molecules are typical for hot cores. These include the neutral molecules HCOOCH3, CH3CH2OH, and CH3COCH3, which are currently believed to exist in the gas phase only in hot cores and shock-heated gas. In addition, vibrationally excited C4H and HC3N lines with upper-level energies of several hundred Kelvins were found. Such lines can arise only in hot gas with temperatures on the order of 100 K or higher. Apart from neutral molecules, various molecular ions were also detected. Some of these (HC18O+, H13CO+, and HCS+) usually exist in molecular clouds with high visual extinctions. Potential formation pathways of complex organic molecules and hydrocarbons, along with nitriles, are considered. These formation routes are first discussed in the context of laboratory experiments elucidating the synthesis of organic molecules in interstellar ices in cold molecular clouds, followed by sublimation into the gas phase in the hot core stage. Thereafter, we discuss the predominant formation of hydrocarbons and their nitriles in the gas phase through bimolecular neutral–neutral reactions.
Three-dimensional General-relativistic Simulations of Neutrino-driven Winds from Rotating Proto-neutron Stars

We explore the effects of rapid rotation on the properties of neutrino-heated winds from proto-neutron stars (PNS) formed in core-collapse supernovae or neutron-star mergers by means of three-dimensional general-relativistic hydrodynamical simulations with M0 neutrino transport. We focus on conditions characteristic of a few seconds into the PNS cooling evolution when the neutrino luminosities obey

erg s−1, and over which most of the wind mass loss will occur. After an initial transient phase, all of our models reach approximately steady-state outflow solutions with positive energies and sonic surfaces captured on the computational grid. Our nonrotating and slower rotating models (angular velocity relative to Keplerian Ω/ΩK ≲ 0.4; spin period P ≳ 2 ms) generate approximately spherically symmetric outflows with properties in good agreement with previous PNS wind studies. By contrast, our most rapidly spinning PNS solutions (Ω/ΩK ≳ 0.75; P ≈ 1 ms) generate outflows focused in the rotational equatorial plane with much higher mass-loss rates (by over an order of magnitude), lower velocities, lower entropy, and lower asymptotic electron fractions, than otherwise similar nonrotating wind solutions. Although such rapidly spinning PNS are likely rare in nature, their atypical nucleosynthetic composition and outsized mass yields could render them important contributors of light neutron-rich nuclei compared to more common slowly rotating PNS birth. Our calculations pave the way to including the combined effects of rotation and a dynamically important large-scale magnetic field on the wind properties within a three-dimensional GRMHD framework.
Invasive Drosophila suzukii outnumbers native controphics and causes substantial damage to fruits of forest plants
Authors: Bühlmann Irene , Gossner Martin
Published: June 2022

Impacts of biological invasions are diverse and can have far-reaching consequences for ecosystems. The spotted wing drosophila, Drosophila suzukii, is a major invasive pest of fruits, which negatively affects fruit and wine production. However, little is known about the ecological impact of this fly species on the ecosystems it has invaded. In this study, we investigated the use of potential host plants by D. suzukii at 64 sites in different forest communities in Switzerland from mid-June to mid-October 2020. We examined more than 12,000 fruits for egg deposits of D. suzukii to assess its direct impact on the plants. We recorded symptoms of fruit decay after egg deposition to determine if D. suzukii attacks trigger fruit decay. In addition, we monitored the drosophilid fauna with cup traps baited with apple cider vinegar, as we expected that D. suzukii would outnumber and potentially outcompete native controphics, especially other drosophilids. Egg deposits of D. suzukii were found on the fruit of 31 of the 39 potential host plant species studied, with 18 species showing an attack rate > 50%. Overall, fruits of Cotoneaster divaricatus (96%), Atropa bella-donna (91%), Rubus fruticosus corylifolius aggr. (91%), Frangula alnus (85%) and Sambucus nigra (83%) were attacked particularly frequently, resulting also in predicted attack probabilities that varied among forest communities. Later and longer fruiting, black fruit colour, larger fruit size and higher pulp pH all positively affected attack rates. More than 50% of the plant species showed severe symptoms of decay after egg deposition, with higher pulp sugar content leading to more severe symptoms. The high fruit attack rate observed was reflected in a high abundance and dominance of D. suzukii in trap catches, independent of forest community and elevation. Drosophila suzukii was by far the most abundant species, accounting for 86% (81,395 individuals) of all drosophilids. The abundance of D. suzukii was negatively associated with the abundance of the native drosophilids. Our results indicate that the invasive D. suzukii competes strongly with other frugivorous species and that its presence has far-reaching ecosystem-level consequences. The rapid decay of fruits attacked by D. suzukii leads to a loss of resources and may disrupt seed-dispersal mutualisms through the reduced consumption of fruits by dispersers such as birds.

Le bricolage comme protestation : les squatteurs réhabiliteurs et la politique du logement à Berlin Ouest pendant les années 1980
Authors: Kreis Reinhild , Robin Guillaume
Published: June 2022

Au début des années 1980, des centaines de personnes en Europe occidentale ont eu recours à un moyen inhabituel pour protester contre leurs conditions de logement et la politique du logement : ils ont rénové de leurs propres mains des maisons vides qu’ils avaient occupées auparavant. L’étude de cas de Berlin-Ouest montre ces « squatteurs d’immeubles » comme des « bricoleurs en guise de protestation ». La pratique artisanale dans la lutte pour les maisons des années 1980 a attiré l’attention du public sur les dysfonctionnements et a démontré en même temps des solutions. La politique, le public et les spécialistes ont été contraints de se pencher sur l’entraide en tant que solution aux problèmes d’urbanisme.
Les acteurs de la mobilité urbaine à Mexico : Les interdépendances au cœur des processus d’intégration
Authors: Tanikawa Obregón Kei
Published: June 2022

La gouvernance de la mobilité urbaine se structure autour d’interdépendances entre acteurs à travers des systèmes socio-techniques complexes. Qu’ils soient publics ou privés, formels ou en marge d’une organisation étatique, les services de transport urbain se heurtent à une cohabitation territoriale et créent ainsi des relations de dépendance réciproques. À l’aune des projets de modernisation du secteur, l’intégration et l’unification des systèmes de transport constituent un horizon balisé des politiques publiques. Les interdépendances entre acteurs (opérateurs et régulateurs) apparaissent alors au cœur des processus de numérisation. Le projet « Mobilité Intégrée » mis en place par l’organisme en charge de la mobilité de la ville de Mexico ( secretaria de movilidad ou SEMOVI) en 2019, constitue un observatoire privilégié pour étudier les interdépendances au sein d’un jeu d’acteurs particulièrement éclaté. Ce travail s’appuie sur des enquêtes de terrain menées début 2021. L’article identifie les interdépendances entre acteurs comme une clé de lecture fondamentale dans la compréhension des politiques et projets d’intégration des systèmes de transport. Il met en évidence les limites de l’organisation sociale et politique face aux défis techniques et aux promesses du numérique. Enfin, il questionne la mise en place d’une mobilité intelligente et son articulation avec le concept de Mobility as a Service (MaaS) dans un contexte de mobilité urbaine fragmentée.

Cette question est au cœur de la gouvernance du territoire de Salé pour organiser le schéma postérieur d’aménagement, de développement durable et d’équité entre les différents citoyens de cette ville. Le développement territorial se mesure sur la valeur ajoutée économique, sur des modes de gestion performant, par l’agencement des différentes communes de la ville selon le modèle d’équilibre territorial dans l’objectif d’égalité à vocations territoriales conciliables, afin de réussir les passages de la rétrospective à la prospective de la ville de Salé de demain. Les ajustements, fondés par la vision d’espaces et de localités communes, voire collectifs dans la ville, sont exigeants en actions et de reconfiguration des urbanités courante par d’autres modalités de gestion et de gouvernance de la ville en vue de créations d’emplois, ces impulsions admettent de dévoiler des éloignements et des adaptations entre les différents intervenants dans la ville, le capital immatériel diversifié, l’accroissement de modes de vie et de la population vivante à Salé et le résultat social en général de la ville. Cet article traite de certains enjeux proposés par l’émergence d’espaces et de lieux publics, voire communautaires, pour la valorisation du patrimoine de la ville de Salé dans une perspective de gouvernance intelligente et de rééquilibrage des mesures économiques et sociales en faveur de la population de la ville de Salé. Deux logiques principales et leur confrontation peuvent nous aider à expliciter notre problématique, sur la base des deux axes suivants : Pratiques et acteurs de gouvernance ; Moyens d’administration et de gestion territoriale de salé ; Salé, centralités organisées autour de l’économie et l’emploi.
Contextes historique, politique et économique de la création architecturale néo mauresque en Algérie 1900-1930
Authors: Chalabi Amina , Lazri Youcef
Published: June 2022

Le début du XX e  siècle a connu un changement radical de politique constructive française en Algérie, marqué par l’abandon progressif de l’architecture néo-classique qui régnait depuis plus d’un demi-siècle, laissant place à une tendance plus humaniste, basé sur la réinterprétation du vocabulaire locale dans des constructions modernes. Cette nouvelle politique est venue rompre avec soixante-dix années d’austérité néo-classique, et dont les traces définissent l’une des grandes lignes d’arabisance observable aujourd’hui ; l’architecture néo mauresque ; un style architectural à portée orientaliste qui était déclaré jusqu’aux années trente style officiel. Comme tout style officiel est à questionner, nous avons essayé, dans la présente étude, d’identifier les origines de sa création, et de cerner les différents contextes dans lesquels il a émergé. Cela à travers une étude historique qui vise une meilleure compréhension de cette fleuraison esthétique qui constitue aujourd’hui un modèle pour des constructions contemporaine à forte connotation identitaire.
Reconstruire et se reconstruire : l’âpre épreuve des poilus de retour dans les régions libérées
Authors: Domain Magali
Published: June 2022

Une étude comparée du célèbre roman de Roland Dorgelès, Le Réveil des morts (Albin Michel, 1923) et du roman plus confidentiel de J.-H. Louwyck, La Nouvelle Épopée (Plon, 1925) nous plonge dans la période de la reconstruction des régions du Nord dans l’immédiat après-guerre. En suivant les parcours très différents de deux soldats de retour des tranchées, Dorgelès et Louwyck évoquent les souffrances physiques et psychologiques de vainqueurs qui ont bien du mal à s’extraire de l’atmosphère d’un conflit dont les traces sont omniprésentes autour d’eux, du fait des ruines et des paysages ravagés qu’il a engendrés. Les conditions de vie déplorables des sinistrés sont également évoquées tandis que l’angoisse d’un possible oubli du sacrifice consenti par leurs camarades combattants étreint les deux héros.
Écriture journalistique, roman et poésie dans trois œuvres de Roland Dorgelès : Sur la route mandarine , La Caravane sans chameaux et Chez les beautés aux dents limées
Authors: Leroy Christian
Published: June 2022

Dans ses premiers reportages en Asie et au Proche Orient, Sur la route mandarine , La Caravane sans chameaux et Chez les beautés aux dents limées , Roland Dorgelès met en avant les exigences de véracité du métier de reporter. Les poussant à un principe de démystification généralisé, il s’affronte à nouveau à l’angoisse et à la mort. Il ne pourra en triompher que par un repli sur un romanesque initialement refusé. Mais cette tension est elle-même dépassée par l’entrée via le rêve dans l’univers de la poésie qu’illustrent traductions de chants annamites ou arabes, citations de poètes français, et véritables poèmes en prose.
The generalized 4-connectivity of folded Petersen cube networks
Authors: Ge Huifen , Zhang Shumin , Ye Chengfu , Hao Rongxia
Published: June 2022

The generalized $ \ell $-connectivity $ \kappa_{\ell}(G) $ of a graph $ G $ is a generalization of classical connectivity $ \kappa(G) $ with $ \kappa_{2}(G) = \kappa(G) $. It serves to measure the capability of connection for any $ \ell $ vertices. The folded Petersen cube network $ FPQ_{n, k} $ can be used to model the topological structure of a communication-efficient multiprocessor. This paper shows that the generalized 4-connectivity of the folded Petersen cube network $ FPQ_{n, k} $ is $ n+3k-1 $. As a corollary, the generalized 3-connectivity of $ FPQ_{n, k} $ also is obtained and the results on the generalized 4-connectivity of hypercube $ Q_n $ and folded Petersen graph $ FP_k $ can be verified. These conclusions provide a foundation for studying the generalized 4-connectivity of Cartesian product graphs.
L’archéologie classique et l’archéologie du bâti
Authors: Marc Jean-Yves
Published: June 2022

L'étude de l'archéologie grecque et romaine a le plus souvent été le fait d'une collaboration entre architectes et archéologues, en particulier dans le cadre des grandes fouilles de la fin du XIXe siècle et du premier tiers du XXe siècle (en Méditerranée orientale mais aussi en Afrique du Nord), du fait de la rencontre de la tradition ancienne des « envois de Rome » et de la naissance de l'archéologie universitaire. Les grandes publications monographiques, qu'elles concernent l'architecture monumentale ou l'architecture domestique, conjoignaient en général une analyse très précise des vestiges (par des relevés pierres à pierres à des échelles très grandes), des propositions de restitution, des études sur les techniques de construction ou le décor architectural et des conclusions typo-chronologiques. La création de l'IRAA du CNRS à la fin des années cinquante, qui a permis d'institutionnaliser cette collaboration et de l'étendre aux travaux menés sur le territoire métropolitain (Orange, Arles, Alésia, etc.), n'a pas entraîné de formalisation ni de théorisation des méthodes employées. Pas plus d'ailleurs que l'émergence de l'archéologie du bâti chez les médiévistes : la part prise par les architectes dans nos publications l'explique peut-être en partie. C'est plutôt la révolution numérique qui a forcé les historiens de l'architecture classique, qu'ils soient architectes ou archéologues, à se poser la question du relevé, du dessin, de la représentation, etc.
Le chevet de l’abbatiale de Saint-Gilles-du-Gard : l’apport du relevé à l’étude d’un chantier monumental dans le Sud de la France à la fin du XIIe siècle
Authors: Hartmann-Virnich Andreas , Hansen Heike , Echtenacher Götz
Published: June 2022

Du chœur de l’abbatiale de Saint-Gilles-du-Gard, endommagé puis démonté en plusieurs phases du XVIe au XIXe siècle, il ne subsiste aujourd’hui que les premières assises d’une majeure partie de son pourtour, et des fragments d’élévation autour du célèbre escalier en vis dont la voûte en berceau hélicoïdal, prototype éponyme de la « vis de Saint-Gilles », valut à cette partie du fameux édifice d’être sauvée de la destruction. Un relevé pierre-à-pierre intégral des vestiges dans le cadre d’un projet collectif de recherche, combinant approche graphique manuelle, tachéométrie laser, photogrammétrie 3D et orthophotographie, donna lieu à une étude très détaillée de cet ouvrage insigne qui fut mis en chantier vers la fin du XIIe siècle. En transposant une synthèse unique d’illustres modèles des XIe et XIIe siècles à l’échelle de l’architecture gothique contemporaine, le concepteur inconnu de l’ouvrage entreprit la mise en œuvre du plus vaste chevet roman à déambulatoire et chapelles rayonnantes de l’architecture romane, resté inachevé. L’analyse du monument, complétée au niveau des fondations partiellement dégagées au cours de deux campagnes de fouilles préventives par de précieuses observations sur les substructions, a révélé un grand nombre d’indices, souvent trop discrets pour se révéler au premier abord, dont la synthèse met en relief les contours et le déroulement d’un chantier bien organisé, et les traces – rarement observables et constatées – du procédé de transposition du plan théorique sur le terrain à bâtir. L’étude archéologique démontre en effet que le temps investi dans la traduction graphique des données récoltées et des mesures prises par le geste du relevé in situ qui les rend perceptibles, et l’étude méthodique intégrale des surfaces murales imposée par cette démarche, sont le prix à payer pour obtenir et comprendre des informations essentielles en vue d’une approche du processus constructif et de la relation ou l’écart entre la réalisation et le projet immatériel.
Observer et documenter les parements et revêtements muraux : photographie et enregistrement du visible et de l’invisible

La photographie et l’appareil photo comme outils d’observation dans le visible et dans l’invisible sont souvent peu employés en archéologie. Là où l’archéologie se focalise sur les applications liées à la photogrammétrie, la communauté des archéomètres travaille sur des techniques in situ sans pour autant exploiter pleinement la photographie et ses possibilités, comme le témoigne la dernière publication du réseau CAI-RN1, intitulée : Instrumentation portable : Quels enjeux pour l'archéométrie ? traitant des méthodes analytiques mises en œuvre in situ2.Cet article a pour vocation d’exposer les différentes possibilités offertes par un simple appareil photo numérique pour l’étude et l’observation du patrimoine bâti. En effet, une fois son capteur défiltré, l’appareil photo est capable de capter une large gamme du spectre électromagnétique (longueurs d’onde comprises entre 300 à 1000 - 1200 nm), soit les rayonnements optiques dans l’ultraviolet (< 380 nm), le visible (380 - 700 nm) et l’infrarouge (> 720 nm). De plus, c’est un outil qui permet de réaliser des images à différentes échelles : macroscopique (avec des objectifs 1:1), mais aussi microscopique (en y adaptant des objectifs de microscope). Il est à noter que ce type d’étude et d’appareillage est aujourd’hui répandu dans d’autres domaines spécifiques de l’archéologie comme la préhistoire et la tracéologie3, mais reste marginal pour les études du bâti. Cet article tend ainsi à dresser un panorama à partir d’exemples d’applications, mais n’est pas exhaustif quant aux possibilités et aux techniques pouvant être utile à l’archéologie. Il vise à répondre spécifiquement à des questionnements propres au bâti. L’objectif principal ici, est donc de pouvoir apporter quelques informations pour pouvoir s’équiper facilement, avec un coût relativement bas et du matériel polyvalent.

A participação feminina no mercado de trabalho vem crescendo nas últimas décadas. Advoga-se que quando mulheres exercem cargos de importância corporativa, como nos conselhos de administração de companhias de capital aberto, há resultados positivos em relação à performance empresarial. No presente estudo, utiliza-se a Teoria da Agência como fundamentação teórica, que tem por objetivo geral investigar a relação entre a participação feminina no conselho de administração e a performance empresarial das empresas listadas na B3 S.A., no período de 2012 a 2017. Para tanto, foi feita uma pesquisa descritiva, de natureza quantitativa, com a aplicação de testes estatísticos de Análise de Correspondências (Anacor) e a estimação de um modelo por Regressão Linear Múltipla de mínimos quadrados ordinários, de dados em painel de efeitos fixos e método generalizado dos momentos com estimador de Arellano-Bond. Os resultados da Anacor mostraram uma correspondência positiva entre a participação feminina e as dimensões de performance empresarial. Quanto às regressões, os resultados não indicaram relação estaticamente significativa entre a presença de mulheres no conselho de administração e os resultados financeiros e operacionais das empresas e o valor de mercado.

Este estudo verificou a influência do CEO Power na probabilidade de sobrevivência das empresas brasileiras no mercado de capitais, considerando o período de 2010 a 2018. A amostra final foi composta por 803 observações de empresas não financeiras ativas na Brasil, Bolsa, Balcão (B3). O método utilizado foi o modelo de Regressão Logística (Logit), o qual utiliza uma variável dependente binária, utilizada nesse estudo para classificar as empresas com maior e menor probabilidade de sobrevivência. O CEO Power (variável de interesse) foi analisado a partir de 4 dimensões do poder, sendo: poder estrutural (Power_Estrut), poder de propriedade (Power_Prop), poder especialista (Power_Esp) e poder de prestígio (Power_Prest). Além dessas foram inseridas variáveis de controle como: tamanho da empresa (Tam), idade do CEO (Ida), alavancagem (Ala), e lucratividade (Lucrat). Os resultados evidenciaram que o Power_Estrut influencia negativamente na probabilidade de sobrevivência das empresas, diminuindo a chance de sobrevivência da empresa em 29,6%, enquanto que para o Power_Prop e Power_Esp, os resultados mostraram que quando o CEO é um dos 5 principais acionistas da empresa ou quando possui formação na área de negócios, a probabilidade de sobrevivência das empresas aumentam em 147,4% e 42,3%, respectivamente. Diante disso, conclui-se que tais resultados são interessantes pois revelam que mesmo em um cenário em que a maioria das empresas possui alta concentração de propriedade (brasileiro), o CEO Power pode ser determinante para a sobrevivência das empresas, ou seja, pode revelar que esses profissionais interferem de alguma forma no desempenho organizacional e na continuidade das firmas.

Authors: Mashifana Tebogo , Sillanpää Mika
Published: June 2022

Waste generation and management in industries is a major problem worldwide. In this study, granulated blast furnace slag (GBFS), fly ash (FA) + cement (CM), and de-silicated foundry sand (DFS) based geopolymers were developed and their leachability studied. The elemental composition showed that the raw materials studied had the highest compositions in SiO2 and Al2O3, which are the constituents desired for the formation of a geopolymer. The GBFS geopolymer had the highest unconfined compressive strength (UCS) of 30.977 MPa, followed by the FA + CM geopolymer with 16.704 MPa. The DFS geopolymer recorded the lowest strength. The mineralogy of GBFS geopolymer showed the presence of an amorphous phase which consisted predominantly of grossite. The FA + CM-based geopolymer had an amorphous and crystalline phase predominated by sillimanite. The DFS-based geopolymer consisted mainly of sodium silicate hydrate. The leaching tests showed that the concentrations of the elements in the leachates were all below the regulatory limits. All of the developed geopolymers were considered environmentally friendly. This study showed that GBFS geopolymer and fly ash + CM-based geopolymers have good durability and leaching behavior, with DFS-based geopolymers possessing poor durability but good leaching behavior. The studied geopolymers are suitable for use as building wall materials and paving bricks without compromising and polluting the environment.

Published: June 2022

Alumina is the most promising ceramic armor material and SHPB testing is typically used to investigate dynamic deformation behaviour and ballistic mechanisms. In this research the effect of the incident wave shaping technique on the stress equilibrium state during testing was analysed. The compressive strength of alumina ceramic materials was evaluated under high strain rate compressive loads of 1200-1800/s. The SHPB compression strength was found to increase with decreasing grain size to a maximum of 3.80±0.25 GPa, and the ceramic materials studied exhibited high strain-rate sensitive mechanical properties due to crack tip inertia effects.

Published: June 2022

The thermal management processes for PhotoVoltaic (PV) cooling applications, increase PV systems’ overall efficiency and yield to a maximized power generation. Accordingly, this paper investigates recent PV thermal management methods, which involve the use of Phase Change Material (PCM) under the back of PV modules. Compared to other cooling methods (such as air and water based methods) PCM based techniques show less need for maintenance, are environment-friendly, and have a longer life cycle. Since PCM are diverse in nature, and many methods exist to guide their selection procedure, this paper begins by revealing different types of PCM, which are found to be as Organic, Inorganic, Eutectic and Commercial PCM, with the characteristics of each. After acknowledging different PCM natures, a selection process is established based on either the melting temperature, latent heat, or thermal conductivity of PCM. Results have shown that Commercial PCM are the best option followed by Organic PCM, due to their improved chemical aspects when compared with Inorganic and Eutectic PCM. Concerning PCM selection criteria, the easiest yet sufficient process is based on the melting temperature method, due to the simplified calculations when compared to other thermic quantities. At the end, future work recommendations are declared, related to PCM lifecycle assessment and cooling/heating cycles effects on PV entropy.

Published: June 2022

Recently, several types of nanomaterials gained attention as promising nanoadsorbents to remove dyes from wastewater such as layered double hydroxides (LDHs). In this work, Fe-Zn-Co-Ni LDH was developed by the basic co-precipitation method. In order to emphasize and characterize the developing of this quaternary LDH, six techniques (x-ray diffraction (XRD), scan electron microscope (SEM), Fourier transforms infrared (FTIR), transmission electron microscope (TEM), zeta potential measurements) have been investigated. The LDH was studied for the uptake of anionic dye, methyl orange (MO), under numerous adsorption factors such as solution pH, contact time, dye initial concentration and adsorbent dosage, and. The XRD data states that the crystallite size of MO@LDH (93.1 nm) is increased compared with that of LDH (12.7 nm) owning to the adsorption of MO onto LDH surface. Two new peaks have appeared for the MO@LDH owning to the bending vibrations of the MO functional groups C-N and C-H. The highest adsorption capacity for the prepared MO@LDH was 418 mg/g and it reached the equilibrium state at 60 min. The adsorption kinetic was obeyed to the pseudo-first order model. Additionally, the LDH showed a positive antibacterial effect towards both Gram-negative and Gram-positive bacteria.

Published: June 2022

Ocular nerve palsies are among the most common cranial neuropathies in neurological practice. Nerves can get affected anywhere along their path from the brainstem to the orbit. There can be isolated involvement of multiple cranial nerves together. The etiologies differ according to the type of presentation. The steps toward the diagnosis need to be strategically planned and must be based on clinical localization. It is crucial to make proper localization to plan further investigations and thus treatment of the etiology. This review covers the approach toward the diagnosis, etiologies involved, and management of ocular cranial neuropathies.

Background and Purpose:

We aimed to explore the characteristics, clinical features, predictors of seizure, and associated clinical outcomes in patients with cerebral venous thrombosis (CVT).

Methods:

We enrolled patients with CVT from January 2014 to July 2020. Prospectively patients were recruited from December 2018. We analyzed predictors of seizures and associated good functional outcomes (modified Rankin Scale, mRS: 0–2) using multivariable logistic regression.

Results:

We enrolled 153 patients with CVT in which 77 (50%) had presented with a seizure. The median age was 31 years (IQR 16-46), and the majority were men (73.2%). Focal to bilateral tonic-clonic was the most common seizure type (27%), followed by generalized seizures (22%). None of the patients had status epilepticus. Antiseizure medications (ASM) were used in 71% of patients at diagnosis, 42% having received them prophylactically. Supratentorial parenchymal involvement was seen in 72% of seizure patients compared to 38% in those without, and superior sagittal sinus was most commonly involved. Percentage of patients who achieved good clinical outcome (mRS 0-2) at 3 months did not vary significantly between both groups. The only predictor for seizures with CVT was the presence of a parenchymal lesion (OR-3.75, 95% CI 1.79-7.85), whereas seizure occurrence (OR- 12.55, 95% CI- 1.53-102.59) was associated with statistically significant risk for recurrent seizures, by multiple logistic regression analysis. Seizure occurrence was not associated with adverse functional outcomes.

Conclusion:

Seizures at presentation occurred in 50% of patients with CVT which was associated with a parenchymal lesion in the brain. There was no association between seizure at presentation and clinical outcome.
