Morphological Characteristics of Genital Organ-Associated Lymphoid Tissue in the Vaginal Vestibule of Goats and Pigs
Authors: Chuluunbaatar Tsolmon , Ichii Osamu , Masum Md. Abdul , Namba Takashi , Kon Yasuhiro
Published: January 2023

Mucosa-associated lymphoid tissue (MALT) is a specialized form of peripheral lymphoid tissue (LT), which is found on mucosal surfaces exposed to the environment. However, morphological data of these tissues in farm animals are scarce. This study investigated the gross anatomical and histological features of genital organ-associated lymphoid tissues (GOALTs) in the vaginal vestibule (VV) of healthy, non-pregnant, adult goats and pigs. Their VVs were composed of stratified squamous, non-keratinized epithelium, and various-sized dark-blue hematoxylin-positive spots were observed in whole-mount specimens, which were diffusely distributed throughout the mucosal surfaces. These spots were histologically identified as LTs and consisted of lymphatic nodules (LNs) or diffuse lymphoid tissue (DLTs). Both LNs and DLTs contained B cells, T cells, macrophages, dendritic cells, plasma cells, and high endothelial venules. Only the numbers of B cells were significantly higher in both the LNs and DLTs of pigs compared to goats. Furthermore, the surface of the VV epithelium covering the LTs was partially disrupted with a large intercellular space containing abundant connective tissue fibers with numerous lymphocytes. In conclusion, GOALTs in the VV appear to be common local immunological barriers in both examined animals. This knowledge is crucial for understanding the structures and disorders of female reproductive organs in farm animals.

Published: January 2023

With digital information technology based on limited data, disaster simulation review is an important guideline for analyzing disaster mechanisms, planning post-disaster reconstruction, and improving defense capability. Taking the “7.20” flash flood in the Wangzongdian river basin as a research area, a hydrological-hydrodynamic model was established using limited measured data. The results showed that the extreme rainstorm caused flooding in mountainous areas and the collapse of subgrade water damming, and the high-level flood quickly flowed into Wangzongdian Village in a short distance, which was the main cause of this serious disaster. Considering the collapse due to the congestion of the upstream bridge, the simulated flood flow in Wangzongdian Village reached 782 m3/s, which was basically consistent with the post-disaster survey results, with a relative error of only +8%. The modeling strategy proposed in this paper is applicable in the review of sudden heavy rainstorms and flash floods and can provide technical guidance for future flash flood simulation review analysis in other areas.
Environmentally Realistic Waterborne Atrazine Exposure Affects Behavior in Poecilia latipinna
Authors: MacLaren R. David
Published: January 2023

The present study examined the effects of environmentally realistic exposure to atrazine (ATZ) on the behavior of sailfin mollies, Poecilia latipinna. ATZ is one of the most commonly used pesticides in the US and a known endocrine disrupting chemical (EDC). The behavior of sailfin mollies is well documented in the scientific literature. Moreover, they are ecologically important indicators of environmental health, widely distributed among the mangroves along the Gulf Coast of the Southeastern US where significant amounts of ATZ are introduced via runoff and storm water drainage from coastal households, businesses, and farms. Four sets of experiments designed to assess ATZ’s impact on various aspects of male and female reproductive behavior, aggression, anxiety, and boldness were conducted following 12 weeks of exposure to 1 or 15 ppb water-borne ATZ, along with a no-exposure control group. Results indicated that the behavior of ATZ-exposed individuals differed from those of controls: ATZ exposure affected which stimulus fish (a male vs. a female) subject females preferred to associate with while also affecting female strength of preference for males of larger body size and their sexual receptivity to conspecific males in general. ATZ-exposed males also showed reduced overall responsiveness to conspecific stimuli and directed significantly less aggression toward their mirror image compared with controls. Finally, ATZ exposure affected multiple aspects of male and female behavior that are often used as proxies for boldness and anxiety. Overall, ATZ exposure resulted in alterations across a variety of behaviors attributed to sexual receptivity, mate choice and motivation to mate, aggression, as well as boldness and anxiety. These ATZ-induced behavioral changes may adversely affect the long-term health of natural populations exposed to similar, environmentally realistic concentrations and add to a growing body of empirical data demonstrating substantial fitness consequences of exposure to sublethal concentrations of this known EDC.

Authors: Zhou Runjuan , Sun Yingke , Chen Wenyuan , Zhang Kuo , Shao Shuai , Zhang Ming
Published: January 2023

In order to control the discharge of regional total pollutants in the region and improve the ability of water environment management and decision making, a multi-objective decision-making optimization model of water pollution load allocation was constructed, which took into account economy and fairness. The model takes the maximum environmental benefit and the minimum weighted comprehensive Gini coefficient as the objective function and takes into account the uncertainty and multi-objectives of the model, which is conducive to promoting economic development and ensuring the fairness of regional water pollutant discharge. A method based on Monte Carlo simulation coupled with a genetic algorithm was designed to obtain the optimal solution set through multiple simulation optimization. This model is applied to Anhui Province to solve the allocation optimization problem of total pollutant reduction in the 13th Five-Year Energy Conservation and Emission Reduction Plan. After the optimization of water pollution load distribution, the comprehensive Gini coefficients of COD and NH3-N are reduced by different ranges. The comprehensive Gini coefficient after COD optimization decreased by 2.4–4.6%, and the comprehensive Gini coefficient after NH3-N optimization decreased by 25.1–32.5%, which verified the feasibility and rationality of the model in the optimal allocation of the total discharge of regional water pollutants. The model takes into account uncertain subjective and objective factors that have an important impact on water pollutant discharge targets and decision variables, thus optimizing the total emissions of the entire regional control unit in both space and time.

The Bednja River is the longest river flowing with its full course exclusively through Croatia and one of the largest right tributaries of the Drava River, which belongs to the Danube River basin. Due to the variety of habitats present within the course of the Bednja River, as well as older literature reports, it can be expected that this river harbors a high number of freshwater fish species and would likely benefit from conservation and preservation efforts. We compiled and analyzed the existing literature data on the Bednja River fish communities and performed field investigations at various localities on this river in order to describe the current structure of its freshwater fish fauna and monitor changes induced by human activities. Our results corroborate the presence of a rich and diverse fish community. Moreover, with 36 native species, the Bednja River harbors one of the richest fish communities in Croatia as well as in the Danube basin. Unfortunately, modifications of the native fish community were evident in the form of local extinctions, reductions in the population abundance of several native species and the presence of non-native species. Habitat degradation and fragmentation were identified as the most serious threats provoking negative effects on the native fish populations, followed by predatory and competitive effects of invasive species.

Published: January 2023

The high affinity of iron-based byproducts for anion removal can facilitate wastewater treatment using membranes functionalized with such byproducts. In this study, a low-cost functional ceramic membrane (LFCM) based on waste cast iron (WCI) was fabricated and applied to remove selenium from aqueous solutions. The effect of roasting (1250 °C) on the raw material properties was analyzed by X-ray diffraction and specific surface area measurements. Upon roasting, zero-valent iron (Fe0) present in WCI was oxidized to hematite (Fe2O3), while the specific surface area of WCI increased from 2.040 to 4.303 m2/g. Raw WCI exhibited the highest Se(IV) and Se(VI) removal capacity among the prepared materials, and Se(IV) could be removed faster and more efficiently than Se(VI). The selenium removal properties of the synthesized LFCM were similar to those of WCI. This membrane could simultaneously and efficiently remove Se(IV) and turbidity-causing substances through filtration. The results are expected to provide insights into the fabrication of ceramic membranes using industrial byproducts for the removal of ionic contaminants from wastewater.

Published: January 2023

Recently, increasing attention has been paid to heavy metals in sludge. However, limited literature could be found on the distribution characteristics of heavy metals in sludge and their potential risks. In this study, sludges from wastewater plants in Jiangsu Province (China) were selected for the investigation of heavy metal loadings, showing that typical heavy metal levels were in the order of Zn > Cu > Cr > Ni > Pb > As > Hg > Cd, ranging from 154 to 2970 mg/kg, 28 to 1150 mg/kg, 10 to 136 mg/kg, 9 to 262 mg/kg, 0 to 79 mg/kg, 12.1 to 41.6 mg/kg, 0.67 to 19.50 mg/kg and 0.21 to 2.77 mg/kg, respectively. Analysis of the typical heavy metal distribution in sludge indicated that Hg, Zn and Cu were obviously influenced by the degree of industrial intensity and exploitation of human activities, while Ni, Cd, Pb, As and Cr were more evenly distributed. Effects of sewage sources and wastewater-treatment processes on heavy metal levels implied that different industrial wastewaters resulted in different metal contents, but the distribution of Ni, Cd, Pb, As and Cr in different treatment processes was similar. Furthermore, Hg and Cd had the strongest ecological risk, with their levels reaching severe, suggesting that sludge was not recommended for agricultural reuse in this study.

The treatment of wastewater is an expensive and energy-extensive practice that not only ensures the power generation requirements to sustain the current energy demands of an increasing human population but also aids in the subsequent removal of enormous quantities of wastewater that need to be treated within the environment. Thus, renewable energy source-based wastewater treatment is one of the recently developing techniques to overcome power generation and environmental contamination issues. In wastewater treatment, microbial fuel cell (MFC) technology has demonstrated a promising potential to evolve as a sustainable approach, with the simultaneous recovery of energy and nutrients to produce bioelectricity that harnesses the ability of electrogenic microbes to oxidize organic contaminants present in wastewater. Since traditional wastewater treatment has various limitations, sustainable implementations of MFCs might be a feasible option in wastewater treatment, green electricity production, biohydrogen synthesis, carbon sequestration, and environmentally sustainable sewage treatment. In MFCs, the electrochemical treatment mechanism is based on anodic oxidation and cathodic reduction reactions, which have been considerably improved by the last few decades of study. However, electricity production by MFCs remains a substantial problem for practical implementations owing to the difficulty in balancing yield with overall system upscaling. This review discusses the developments in MFC technologies, including improvements to their structural architecture, integration with different novel biocatalysts and biocathode, anode, and cathode materials, various microbial community interactions and substrates to be used, and the removal of contaminants. Furthermore, it focuses on providing critical insights and analyzing various types, processes, applications, challenges, and futuristic aspects of wastewater treatment-related MFCs and thus sustainable resource recovery. With appropriate planning and further studies, we look forward to the industrialization of MFCs in the near future, with the idea that this will lead to greener fuels and a cleaner environment for all of mankind.

Authors: Hua Guowei , Wang Shijie , Xiao Meng , Hu Shaohua
Published: January 2023

Dam safety is considerably affected by seepage, and uplift pressure is a key indicator of dam seepage. Thus, making accurate predictions of uplift pressure trends can improve dam hazard forecasting. In this study, a convolutional neural network, (CNN)-gated recurrent neural network, (GRU)-based uplift pressure prediction model was developed, which included the CNN model’s feature extractability and the GRU model’s learnability for time series correlation data. Then, the model performance was verified using a dam as an example. The results showed that the mean absolute errors (MAEs) of the CNN-GRU model were 0.1554, 0.0398, 0.2306, and 0.1827, and the root mean square errors (RMSEs) were 0.1903, 0.0548, 0.2916, and 0.2127. The prediction performance was better than that of the particle swarm optimization–back propagation (PSO-BP), artificial bee colony optimization–support vector machines (ABC-SVM), GRU, long short-term memory network (LSTM), and CNN-LSTM models. The method improves the utilization rate of dam safety monitoring results and has engineering utility for safe dam operations.
Impacts of Spatiotemporal Gaps in Satellite Soil Moisture Data on Hydrological Data Assimilation
Authors: Mohammed Khaled , Leconte Robert , Trudel Mélanie
Published: January 2023

Soil moisture modeling is necessary for many hydrometeorological and agricultural applications. One of the ways in which the modeling of soil moisture (SM) can be improved is by assimilating SM observations to update the model states. Remotely sensed SM observations are prone to being riddled with data discontinuities, namely in the horizontal and vertical spatial, and temporal, dimensions. In this study, a set of synthetic experiments were designed to assess how much impact each of these individual components of spatiotemporal gaps can have on the modeling performance of SM, as well as streamflow. The results show that not having root-zone SM estimates from satellite derived observations is most impactful in terms of the modeling performance. Having temporal gaps and horizontal spatial gaps in the satellite SM data also impacts the modeling performance, but to a lesser degree. Real-data experiments with the remotely sensed Soil Moisture Active Passive (SMAP) product generally brought improvements to the SM modeling performance in the upper soil layers, but to a lesser degree in the bottom soil layer. The updating of the model SM states with observations also resulted in some improvements in the streamflow modeling performance during the synthetic experiments, but not during the real-data experiments.

Published: January 2023

Leakages in distribution networks reach more than 30% of the water supplied, entailing important risks for the water infrastructure with water contamination issues. Therefore, it is necessary to develop new methods to mitigate the amount of water wastes. This study proposes to seek new sources of information that can help for a more sustainable water use. Hence, an analysis of the network is presented, showing the hydraulic behavior during leaks occurrence, placing emphasis on how these events affect and modify water quality parameters, such as water age and chlorine concentration. The study enhances that water quality data can be an effective source of information in the case of leaks, being a possible source of information for future detection systems. In addition, this study proposes to use graph theory on the water network. The results highlight how an analysis of the shortest path between the leak location and the reservoir could provide meaningful information for future detection systems.
Melanocytic nevus of the anal canal and granular cell tumor of the cecum: a case report and literature review of 2 coincidentally co-occurring neurocristopathies

Published: January 2023

Granular cell tumors are predominantly benign soft tissue tumors originating from Schwann cells, whereas melanocytic nevi are benign proliferations of melanocytes. We present the case of a patient with the presence of both entities located in the cecum and anal canal, respectively, constituting an extremely rare coincidental finding. A 43-year-old woman was evaluated by colonoscopy for iron-deficiency microcytic anemia that had lasted for 1 year. Colonoscopy demonstrated a macular lesion of 0.3 cm with a melanocytic appearance in the anal canal; at the cecum level, a subepithelial, yellowish, and partially mobile firm nodular lesion measuring 1.3 cm was observed. A histopathological study showed a melanocytic nevus in the anal canal and a granular cell tumor in the cecum. This is the first reported case of a patient with the extremely rare coincidental-incidental finding of these 2 entities at the same time.

Évaluation de la réforme des infirmiers diplômés d’État sur les dynamiques de carrière et la retraite : une approche par microsimulation
Authors: Dorin Christophe , Marino Anthony , Rabaté Simon , Soulat Laurent
Published: January 2023

En 2010, le statut des infirmiers fonctionnaires a été réformé : sortie des emplois de la catégorie active en échange d’une revalorisation des grilles. Nous évaluons cette réforme ex ante en comparant la carrière et la retraite dans l’ancien et dans le nouveau statut avec le modèle de microsimulation Canopée appliqué aux fonctionnaires territoriaux et hospitaliers. Pour l’individu, sur l’ensemble de la retraite, la hausse de pension (en moyenne de 27% pour une hausse annuelle des salaires de 1,3 %) compense largement le report de l’âge de départ (de 3,6 ans). Pour le régime de retraite, le bilan dépend des hypothèses d’actualisation.
Les économies de densité dans les services d’aide à domicile aux personnes âgées : une analyse économétrique
Authors: Bensaïd Bernard , Croiset Solen , Gary-Bobo Robert
Published: January 2023

En nous appuyant sur un ensemble de données unique en son genre, reflétant de manière détaillée l’activité du personnel d’un réseau national associatif de Services d’aide et d’accompagnement à domicile (SAAD), aidant les personnes âgées dépendantes, nous mettons en évidence l’existence de fortes économies de densité : le nombre de kilomètres parcourus par les employés des services, par heure de prestation à domicile, décroît avec le nombre d’heures de prestation effectuées dans une période de temps donnée. Ainsi, nous estimons qu’environ 200 millions de kilomètres sont gaspillés par an et qu’on pourrait économiser desmilliers de tonnes de CO2. Ces résultats sont obtenus avec des techniques de régression classiques, en exploitant la structure de panel des données. On trouve qu’un modèle quadratique en logarithmes donne des estimations robustes, et fait apparaître des coûts de transport par heures de prestation en forme de U. Nous en tirons certaines conséquences en termes de régulation, laissant entrevoir la possibilité d’améliorations de l’efficacité économique du secteur et des économies pour les finances publiques.
Paysages et urbanisation sur la côte sud des Landes

Published: January 2023

La Côte sud des Landes, bien que soumise à un double processus d'urbanisation, dispose d'un environnement préservé. Les grands projets de complexes touristiques, au début des années 1990, ont soulevé d'amples débats sur les choix d'aménagement et de développement opposant tourisme et environnement et posé la question de la protection des espaces dans le contexte de l'application de la loi littoral. L'environnement est devenu enjeu territorial : autour de la nature et du paysage reconnu comme patrimoine, un consensus va s 'établir localement.
Effets de proximité et développement métropolitain des services de haut niveau : le cas de Toulouse
Authors: Zuliani Jean-Marc
Published: January 2023

Une forte monopolisation régionale du développement des services marchands de haut niveau caractérise la métropole toulousaine. La croissance cumulative de ces fonctions s'explique par la prééminence de liens localisés de proximité qui prennent un contenu différencié selon les branches sectorielles de services. Favorisés par la demande industrielle et tertiaire consommatrice de systèmes d'information, les services technologiques initient une forme endogène de développement au cœur du territoire régional. Le reste des fonctions prestataires de haut niveau conforte la vocation de place intermédiaire de la métropole pour structurer un flux de services entre un hinterland régional étendu aux marges de Midi-Pyrénées et le niveau supérieur des marchés nationaux et internationaux.
Filières de qualité et ancrage au terroir : la délimitation des zones d'AOC fromagères

Les AOC fromagères protègent des produits d'une qualité particulière, liée à un terroir, c'est-à-dire au respect d'usages spécifiques de production établis à l'intérieur d'une zone de production strictement définie. Depuis 1990, la délimitation des zones d'AOC est réalisée par l'INAO. Cet article précise les conditions d'élaboration de ces zones d'AOC dans le cadre d'un processus bien codifié qui associe le syndicat de produit demandeur, une commission d'enquête et une commission d'experts.

Liés aux tendances musicales actuelles, les Centres et Écoles de Musiques Amplifiées sont apparus comme une nouvelle forme d'équipement culturel. En Aquitaine, quelques d'entrepreneurs associatifs, une élue locale innovante et certains services de l'État ont contribué à la création d'un réseau musical remarquable et d'équipements de référence nationale. La naissance de ces centres correspond aux logiques de métropolisation. Leur diffusion part du centre de la métropole régionale vers sa périphérie pour atteindre progressivement les villes moyennes, en quête de renouvellement de leurs politiques culturelles. Établissements socio-culturels autant que culturels, ils interrogent les politiques publiques en démontrant leur capacité d'être l'écho de l'expression des jeunes et des quartiers fragiles. Ils indiquent un nouveau mode de développement culturel traitant des rapports entre les centres et périphéries.

L'analyse dendrochronologique de hêtres (Fagus sylvatica L.) prélevés dans le massif d'Iraty, Pays basque français, nous permet d'analyser les arbres vivants les plus vieux, pour cette essence, jamais mentionnés dans la bibliographie. Tout au long de la chronologie, longue de 478 ans, des phases durant lesquelles se succèdent des séries de cernes épais ou minces sont observées et analysées. Des individus de plus de trois cents ans affichent une reprise de croissance dès la fin de la première moitié du XIXe siècle et encore plus évidente depuis les années 1950. Les séries de petits cernes sont mises en relation avec les phases de refroidissement du Petit Âge Glaciaire.
Autoroute et territoires en Libournais : derrière l'intercommunalité, le retour en force des représentations et des enjeux communaux
Authors: Di Méo Guy , Gatineau Laurent
Published: January 2023

En Libournais, la nouvelle autoroute A 89 contribue, par ses nuisances et ses enjeux, à renforcer les identités communales. Depuis peu, de nouvelles communautés de communes et un « pays », imposés ou encouragés dans leur principe par l'État, ont vu le jour. Hostiles à Libourne, à la confiscation du pouvoir local et aux charges fiscales qu'elle pourrait infliger aux communes rurales qui les composent, les communautés refusent d'intégrer la ville. Conservatrices, elles épousent l'échelle cantonale des coopérations traditionnelles. Derrière le discours pessimiste sur l'autoroute perce pourtant l'espoir d'un développement autonome, dans l'orbite du grand Bordeaux.
L'intercommunalité sportive, moteur d'une nouvelle gouvernance sportive locale ?
Authors: Bayeux Patrick
Published: January 2023

Sports intertown community, as the engine of a new local sports governance ? Sports, not mentioned in the decentralisation laws, were taken into account by the Chevènement and Voiney Laws. Still they do not assume a compulsory competency and remain submitted to the political decisions of deliberative assemblies. After analysing how the laws are implemented from the juridical viewpoint, the writer shows the general situation on the national level, and particularly in the South West. He then shows how this reshuffling of the territory is such that it could create a new authority on the local level. After foretelling the evolution of sports politics according to a number of relevant territories, to which fragmented competencies may be linked up, he wonders about the bases of a new decision-making process.
La vigne, un facteur de construction territoriale en Aquitaine
Authors: Hinnewinkel Jean-Claude
Published: January 2023

En Aquitaine, la vigne est présente dans la majorité des espaces communaux, à l'exception de la grande forêt landaise et de la chaîne pyrénéenne. Si souvent il s'agit de traces modestes d'un vignoble aujourd'hui rétracté, les grands vignobles du nord de la région forment, à cheval sur la Garonne et la Dordogne, un ensemble compact où la vigne occupe l'essentiel de la SAU. Entre les deux des îlots de viticulture correspondent à des appellations localisées dans les trois départements méridionaux. Dans quelle mesure grands vignobles, comme îlots de viticulture, constituent-ils un territoire ? L'Aquitaine dans son ensemble peut-elle être qualifiée de territoire viticole ? Pour essayer de répondre à cette problématique, nous retiendrons comme définition du territoire, un espace associant une infrastructure géographique, historique et économique bien marquée soutenue par une superstructure idéologique et politique affirmée qu'elle conforte en retour.
Marques ou châteaux ; quel négoce à Bordeaux dans les années 2000 ?
Authors: Rejalot Michel
Published: January 2023

Si le vignoble girondin est un sujet de curiosité renouvelée des géographes, le négoce l'est beaucoup moins, bien que les pratiques commerciales se modifient sans cesse. On pourrait penser que, face à la montée en puissance du concept de « château viticole » et face à l'offensive de nouveaux venus dans la planète vin, le négoce bordelais subit les changements plus qu 'il ne les entraîne, voire qu 'il est en crise. Mais c'est sans doute un regard superficiel. Si de nombreuses maisons ont connu de sérieuses difficultés, beaucoup d'autres sont dynamiques et performantes. En fait, c'est le métier même de négociant qui connaît une rénovation totale. Progressivement, un négoce de plus en plus volontariste fait entendre sa voix et partager ses options, lesquelles pourraient faire de lui à l'avenir non seulement un meilleur outil de conquête des marchés pour toute la filière bordeaux, mais aussi un acteur direct au cœur du vignoble.
Gestion des champs abandonnés pour le développement de l'élevage extensif dans les Pyrénées centrales espagnoles
Authors: Lasanta Martínez Teodoro
Published: January 2023

Gestion de campos abandonados para el desarrollo de la ganadería extensiva en el Pirineo central español.

Los campos abandonados ocupan una superficie muy amplia en el Pirineo español. En la actualidad están cubiertos por matorral y aportan muy poco a la alimentación del ganado. Los objetivos de este trabajo son delimitar posibles campos abandonados que podrían desbrozarse y ser utilizados como prados con el fin de disminuir el actual desequilibrio estacional en pastos. A partir de un Sistema de Información Cartográfica (SIG) se han cartografiado los campos recuperables en función de factor-es topográficos y de accesibilidad. Por otro lado, se aporta información sobre el Valor Pastoral de dichos campos y se ha calculado en qué medida su cambio de uso (de campos abandonados a prados) repercutiría en la disminución del desequilibrio estacional de pastos. Finalmente se discute sobre las ventajas medioambientales y paisajísticas que tendría el desbroce del matorral.
L'expansion hydro-électrique de la haute vallée de l'Èbre au XXe siècle
Authors: Garrues Irurzun Josean
Published: January 2023

Los recursos hidroeléctricos ocuparon un lugar muy relevante -aunque todavía poco conocido- en las primeras fases del sector eléctrico español. La electricidad conseguida a través de pequeñas y medianas compañías sirvió para modernizar industrias y dotar de luz a muchas poblaciones, eliminando antiguas restricciones energéticas. Después del primer franquismo, sin embargo, la crisis los sistemas eléctricos tradicionales se hizo insalvable, toda vez que éstos fueron incapaces de dar cobertura a las nuevas exigencias de la demanda y que las grandes eléctricas asumieron la conquista de los mercados periféricos. En la actualidad, fruto de cambios tecnológicos e institucionales, las viejas fuentes de energía hidroeléctrica han recobrado un valor cualitativo y ecológico nada despreciable, eso sí, dentro de programas globales que priman el ahorro y la diversificación energética.
Le paysage des Hautes-Côtes de Beaune : de la vision du «dedans» à la vision du «dessus»
Authors: Legouy Francois
Published: January 2023

El paisaje de Hautes-Côtes de Beaune : de la vision del "interior" a la vision "desde arriba". El paisaje es un concepto fundamental en geografía, pero que se ha de utilizar con precaución. La confusión entre el análisis paisajístico y el análisis espacial es frecuente, tanto en el fondo como en los términos empleados. El objeto de este articulo consiste precisamente en recordar que las dos lecturas, paisaje y espacio son diferentes y complementarias. Una requiere la visión del "interior", la otra, la visión "desde arriba". El concepto de unidad espaciopaisajística permite relacionar las tres dimensiones del paisaje y del espacio, permite pasar de la visión oblicua a la visión vertical. El análisis paisajístico recurre a las estructuras socioespaciales, presentes y pasadas, generadoras del paisaje, espejo de la sociedad que lo produjo. El ejemplo de los paisajes de Nantoux en las Hautes-Côtes de Beaune (Borgoña) ilustra esta tesis.

La synecdoque paysagère, une notion pour comprendre les représentations des paysages viticoles bourguignon et bordelais
Authors: Bigando Eva
Published: January 2023

La notion de « synecdoque paysagère » se présente comme une clé de compréhension du décalage entre la réalité d'une région viticole, marquée par la variété et la complexité de son ou de ses paysages, et sa représentation réduite à l'image d'un seul de ses éléments paysagers constitutifs. Après un premier point définitionnel, ce texte montre en quoi l'image retenue des paysages viticoles bordelais et bourguignon relève d'une mise en représentation synecdochique. Il s'intéresse ensuite à la manière dont cette image est récupérée par les acteurs en charge de la communication, que ce soit au sein de la filière vitivinicole ou dans le secteur du tourisme.
L'interculturalité dans le quartier Saint-Michel à Bordeaux : pratiques et représentations d'un territoire vécu
Authors: Goudichaud Olivier
Published: January 2023

L' interculturel - la mixité ethnique et les interrelations sociales qui la caractérisent - semble se vivre à Saint- Michel, imprégnant son temps et son espace ordinaires des influences culturelles les plus diverses. Tournure prise par les pratiques sociales, notamment dans leurs rapports aux lieux, transposée en modèle culturel et sociétal, l'interculturalité ne qualifie que superficiellement, marginalement, voire artificiellement la manière de vivre la ville aujourd'hui. L'interethnicité, dans ses fondements, dans son vécu et dans sa substance urbaine reste profondément marquée par le poids déterminant d'une sphère mêlant idéologies, cultures et représentations ; souvent au détriment de réalités plus concrètes, plus matérielles.
Bordeaux, au rythme des cultures sportives
Authors: Augustin Jean-Pierre
Published: January 2023

Depuis plus de trente ans, les cultures sportives s'approprient l'espace urbain et périurbain et rythment le temps des villes. Les sports de compétition se sont développés, le spectacle sportif envahit les média, les pratiques autorégulées dans les espaces publics se sont multipliées et le désir de nature et de mobilité n'a fait que s'accentuer. Ces évolutions touchent l'ensemble de la société française mais elles prennent à Bordeaux des configurations particulières en raison d'une histoire originale, d'un rapport spécifique aux lieux et des modes particuliers de gestion locale qui donnent une coloration propre au vécu et à l'imaginaire des cultures sportives bordelaises.
Quelle place pour les agriculteurs de la Région Métropolitaine de Barcelone? Le cas du delta du Llobregat
Authors: Sempere Roig Jordi
Published: January 2023

¿ Qué lugar para los agricultores en la región metropolitana de Barcelona ? El caso del delta del Llobregat.

El delta del Llobregat ha sido tradicionalmente un espacio privilegiado para las prácticas agrícolas. No obstante, la presión urbanística debida a la expansión de la ciudad, con sus infraestructuras, vías de comunicación, industrias e instalaciones de servicios, ha frenado el progreso agrícola. El sector agrícola es ya minoritario en el área metropolitana y los agricultores no pueden evitar la desaparición de tierras agrícolas. De hecho, a menudo son ellos mismos los agentes activos de la reconversión de parcelas. Las instituciones proponen soluciones, pero el problema se hace grave en Cataluña cuando es la profesión de agricultor la que es cuestionada. En este contexto, la función productiva de los agricultores debe encontrar su lugar en los espacios periurbanos multifuncionales.
As escolas de negócios, na geração de inovação e competências gerenciais complexas em tempos de internacionalização

Published: January 2023

Esse trabalho é um recorte de um projeto sobre “A aprendizagem de competências gerenciais complexas para a formação gerencial: um estudo Luso-Brasileiro com empreendedores da Indústria Criativa”, em parceria com o Instituto Superior de Economia e Gestão (ISEG) de Lisboa/Portugal. Assim, o objetivo desse trabalho é o de avançar na compreensão de uma epistemologia gerencial adequada ao ensino da pós-graduação lato sensu, além de investigar como os discentes podem aprender mobilizar e utilizar competências gerenciais complexas no seu dia-a-dia. Assumiu-se como chave metodológica orientadora da pesquisa o método qualitativo. Justifica-se a escolha deste método, pois segundo Marshall e Rossman (1999), os métodos qualitativos são apropriados para gêneros de pesquisas que são remetidos ao seu ambiente natural e com aproximações exploratórias de dados. A coleta de dados se constituirá de (a) fontes documentais, compondo um corpus documental; (b) entrevistas individuais em profundidade com coordenadores da escola e docentes que ministram aulas relacionadas à formação gerencial Trata-se de uma contribuição, ainda em desenvolvimento, baseada em experiências de pesquisa e consultoria, o que a coloca, portanto, no contexto de uma construção em "pleno movimento", com todos os riscos, problemas e simplificações de um processo de tal tipo.  Os resultados da pesquisa podem direcionar o desenvolvimento de novos produtos e serviços para a pós-graduação e extensão, já que este tem um público alvo (executivos e organizações) crescente ano após ano na busca de qualificação e educação qualificada. A articulação destes resultados com programas Strito Sensu, poderão inclusive fomentar o desenvolvimento de soluções transdisciplinares na formação gerencial e educação corporativa, com inclusão de educação a distância (EAD), na forma de espaços de convivência digital.
Políticas educacionais e medidas políticas para o combate à pandemia da COVID-19: atividades e lógicas de (re) ações dos gestores, docentes e estudantes das universidades angolanas
Authors: Pedro Lando Emanuel Ludi , Brás Chocolate Adão
Published: January 2023

Este artigo tem como objeto as políticas educacionais em tempos de emergência, procurando analisar alguns dados recolhidos num estudo, de carácter mais extensivo, através de 3 entrevistas semiestruturadas e questionário “online” recorrendo à Google Forms a gestores, docentes e estudantes, de um total de 61 instituições de ensino superior em Angola, sendo 24% públicas e 76% privadas. Centrámos a nossa análise nas dimensões referentes à intervenção do Estado, focalizadas para as medidas políticas ligadas a gestão de crise e à política de financiamento das Instituições de Ensino Superior durante o seu encerramento e às atividades de ensino à distância. O estudo baseia-se numa abordagem mista de investigação ao recolher e analisar os dados qualitativos quantitativos num único estudo em simultâneo, possibilitando a confrontação e comparação entre o referente e o referido. Os resultados sinalizam algum distanciamento das medidas políticas em reposta à pandemia tomadas pelo governo em relação à expectativa dos gestores, docentes e estudantes, sobretudo em relação ao pagamento de propinas sem aulas presenciais, a ausência de condições para a realização de atividades académicas à distância e o fraco investimento na investigação científica.
Paradigmas de formação de professores em cursos de licenciatura em química na região da Amazônia legal brasileira: em foco o estado do Acre
Authors: Costa Roger Vinicius Nunes Queiroz da , Ribeiro Marcel Thiago Damasceno
Published: January 2023

Este trabalho é um recorte do projeto de pesquisa do Mestrado, em andamento, vinculado ao Programa de Pós-Graduação em Educação, da Universidade Federal de Mato Grosso. Almeja-se estudar os paradigmas de formação docente em cursos de Licenciatura em Química de Instituições de Ensino Superior (IES) pública, tendo o Estado do Acre como recorte da Região da Amazônia Legal brasileira. Neste sentido, lançamos nossos olhares aos textos que permitem observar relações dos Estágios Supervisionados (ES) e Prática como Componente Curricular (PCC) nos Projetos Pedagógicos dos Cursos (PPC), e a política de formação de professores, produzida nos contextos internacional e nacional. Assume-se o estudo de caso como método de pesquisa, e a mesma se baseará nos Projetos Pedagógicos de Cursos de Licenciatura em Química no Estado do Acre da Região na Amazônia Legal brasileira, tanto presencial quanto a Distância (EaD) de IES pública, nos documentos oficias de diretrizes de formação de professores, na revisão de literatura sobre a temática pesquisada, em busca de possíveis respostas as questões problematizadoras postas neste projeto, com o intuito de produzir textos de pesquisa por meio de interpretações, em diálogo com a literatura, contribuindo dessa forma para a reflexão e formação de professores de Química para a região amazônica do Brasil.
Produção de cerveja artesanal adicionada de gengibre (Zingiber officinale)
Authors: Dutra Messias Junio Moura , Lima Elouise Honorina de França , Dos Santos Wenderson Gomes , De Castro Douglas Alberto Rocha
Published: January 2023

A cerveja, sendo uma das bebidas mais consumidas no mundo, é originada a partir da fermentação do mosto cervejeiro obtido através de quatro ingredientes básicos: malte, água, lúpulo e leveduras. O próprio processo produtivo da cerveja propõe um extenso leque de variedades com relação ao sabor e suas características básicas. O objetivo deste trabalho foi produzir artesanalmente uma cerveja do tipo Pilsen fermentando o mosto cervejeiro sob as temperaturas de 12 °C nos primeiros 8 dias e a 0 ºC por mais 8 dias e avaliou-se como essa variação altera suas variáveis físico-químicas. As cervejas foram analisadas quanto à densidade relativa por meio da utilização de um picnómetro, teor alcoólico através de equações utilizadas no meio da produção de cerveja artesanal, acidez total por meio da titulação com hidróxido de sódio 0,1 M e pH através de um phmetro e elétrodos. Após a análise dos resultados obtidos, a cerveja artesanal adicionada de gengibre apresentou valores de densidade relativa, pH, teor alcoólico e acidez total titulável inferiores com relação à amostra que não tem gengibre, portanto, todas as variáveis indicam que a amostra adicionada de gengibre teve rendimentos favoráveis. De forma geral, as duas amostras apresentaram características físico-químicas esperadas para uma cerveja do tipo Pilsen.
A percepção do bioma cerrado por estudantes do Instituto Federal de Educação, Ciência e Tecnologia de Goiás (IFG), Brasil

O Cerrado é o segundo maior bioma brasileiro, abrangendo 22,65% do território nacional, considerando sua área contínua. O espaço geográfico ocupado pelo bioma desempenha papel fundamental no processo de distribuição dos recursos hídricos pelo país, constituindo-se o local de origem das grandes regiões hidrográficas brasileiras e do continente sul-americano. É considerado a savana mais biodiversa do planeta. A diversidade cultural é ampla e rica em conhecimentos. Desde os povos indígenas, historicamente territorializados, passando pelas comunidades quilombolas, até a diversidade camponesa existente no bioma, compõem um mosaico de saberes que podem ser inseridos no arcabouço da diversidade do Cerrado. Este bioma é determinante para a formação da identidade da população do Brasil Central. A degradação das áreas de Cerrado é relativamente recente. Numerosas espécies de plantas e animais estão ameaçadas ou correm risco de extinção, enquadrando o bioma como um dos hotspots da biodiversidade planetária. O Instituto Federal de Goiás está localizado nesse território. Conhecer a percepção do público discente frente ao Cerrado é extremante importante, pois, permitirá o desenvolvimento de ações de ensino, de pesquisa e de extensão, com foco no bioma/território Cerrado, cumprindo, assim, a missão do IFG, que é a de oferecer educação pública, gratuita e de qualidade, voltada não apenas para o atendimento a perspectivas de empregabilidade, mas também para a formação completa do cidadão. Mediante pesquisa realizada junto aos estudantes de dois câmpus da instituição, verificou-se que o conhecimento acerca do espaço onde estão inseridos, o Cerrado, precisa ser aprofundado e ressignificado.
