Resumen: Henry van de Velde es uno de los arquitectos más polifacéticos de la historia de la arquitectura del siglo pasado, tanto por su obra como por la versatilidad de las estrategias que emplea a lo largo de su trayectoria. El autor belga se acercó a multitud de disciplinas artísticas, dejándose influenciar por ideas del Arts & Crafts de William Morris, vinculándose a los inicios del Art Nouveau o involucrándose en el Deutscher Werkbund hasta 1914. El desarrollo de esta actitud multidisciplinar, síntoma de su evolución creativa, vive uno de los episodios más intensos durante su vinculación laboral con el matrimonio de coleccionistas de arte moderno Kröller-Müller en los Países Bajos. La presente investigación desgrana el legado gráfico y arquitectónico de Henry van de Velde al servicio de los Kröller-Müller, desde los primeros bocetos en los años 20 hasta la ejecución del museo de 1936-57. Un verdadero ejemplo de materialización de sueño arquitectónico.

Abstract: Henry van de Velde is one of the most multifaceted architects in the history of architecture in the last century, both in terms of his work and the versatility of the strategies he employed throughout his career. The Belgian architect drew close to a multitude of artistic disciplines, allowing himself to be influenced by the ideas of William Morris's Arts & Crafts, linking himself to the beginnings of Art Nouveau or becoming involved in the Deutscher Werkbund until 1914. The development of this multidisciplinary attitude, a symptom of his creative evolution, experienced one of its most intense episodes during his working relationship with the Kröller-Müller couple of modern art collectors in the Netherlands. This research unravels Henry van de Velde's graphic and architectural legacy in the service of the Kröller-Müller family, from the first sketches in the 1920s to the execution of the museum in 1936-57. A true example of the realisation of an architectural dream.

Abstract: This investigation compared the efficiency of a flat-plate solar collector with triangular and square geometry, by using the finite element method (FEM). The design of the geometries and the utilized parameters for the simulation were obtained from previous publications. SolidWorks was used to model the two collectors, meanwhile, the Fluent module of the ANSYS software was used for the simulation by the FEM. Collectors integrated a pipe of 7 mm internal diameter with a plate thickness of 11 mm; the defined material was aluminum. The experiment was conducted under ambient conditions at a temperature of 20 °C, accompanied by a solar radiation intensity of 1000 W·m-2. The heat transfer surfaces employed were 61 250 mm2 for the triangular collector and 122 500 mm2 for the square collector. The quality of the mesh was excellent, obtaining a skewness of 0.2486, with which efficiencies of 62 and 39 % and maximum temperatures of 27 and 25.5 °C were obtained for the triangular and square collectors, respectively. Due to the geometries performing as fins, the temperatures are higher in the corners and, therefore, achieving higher efficiency is impossible.

Resumen: En esta investigación, se comparó la eficiencia de un colector solar de placa plana con geometría triangular y cuadrada, a través del enfoque del método de elementos finitos (FEM, por sus siglas en inglés), se llevó a cabo la simulación. Las geometrías y los parámetros empleados en la simulación fueron extraídos de investigaciones previamente publicadas. Se utilizó el software SolidWorks para el modelado de los dos colectores, mientras que el módulo Fluent del software ANSYS fue utilizado para la simulación por el método FEM. Para los colectores se utilizó una tubería de 7 mm de diámetro interno, con un espesor de placa de 11 mm y de aluminio. Se consideró temperatura ambiente de 20 °C, con una radiación solar de 1000 W·m-2 y superficies de transferencia de calor 61 250 y 122 500 mm2 para el colector triangular y cuadrado, respectivamente. La calidad del mallado fue excelente, alcanzando skewness de 0.2486. De esta manera, luego del proceso de simulación se obtuvo eficiencias de 62 y 39 % y temperaturas máximas de 27 y 25.5 °C para el colector triangular y cuadrado, respectivamente. Debido a que las geometrías actúan como aletas, las temperaturas son más altas en las esquinas y por esto no es posible alcanzar mayor eficiencia.

Abstract Recent events involving iron ore tailings dam collapses have emphasized the need for developing alternative ways of depositing tailings. This study aims to evaluate the effects of using three hydroxamates and a sulfosuccinamate as collectors in the direct flotation of iron ore tailings, using a bench flotation. The best result obtained on bench flotation was tested in a pneumatic cell. The sample used in this study (10.8% of Fe) consists of quartz and hematite. The Aero® 6494 Promoter hydroxamate showed the highest selectivity among the analyzed reagents, reaching 64.31% of Fe in the final product of the test with the < 150 µm sample. The possibility of using these reagents as constituents of a mixed collector with dodecylamine was also investigated. In this case, the Aero® 845 Promoter sulfosuccinamate yielded the best results, with 62.84% of Fe and 59.01% of metallurgical recovery of Fe. The synergistic effect between the two reagents might be explained by the stability of the monolayer formed by the intercalation of the ions from the dodecylamine and the Aero® 845 Promoter, which reduces the electrostatic repulsion between ions of the same species This mixed collector was tested in a pneumatic cell. However, it had a lower performance in terms of Fe metallurgical recovery than in a bench-scale cell test, mainly for the finest particles, due to the greater control of the process’s variables in the bench cell. 10.8% 108 10 8 (10.8 hematite Aero 649 6431 64 31 64.31 15 investigated case 84 results 6284 62 62.84 5901 59 01 59.01 However benchscale scale particles processs process s 10.8 1 (10. 643 6 3 64.3 628 62.8 590 5 0 59.0 10.

Abstract This article scrutinizes the National Policy on Solid Waste (PNRS) - Law 12.305/2010 regarding the collective and diffuse rights of collectors of recyclable materials. More than a decade since the enactment of the PNRS, the rights bestowed by this legislation have yet to be actualized. In its analysis, the article highlights public-interest civil actions pertaining to the cities of São Paulo (SP), Rio de Janeiro (RJ), and Brasília (DF). The hypothetical-deductive method was employed within a qualitative framework, utilizing both bibliographic and documentary research tools. It is concluded that, due to governmental neglect, there is an imperative for the ongoing involvement of the Public Prosecutor’s Office and the Public Defender’s Office to advocate for and safeguard the rights of this worker category, which are pivotal in the advancement of a sustainable environment.

ABSTRACT The knowledge of the diversity and distribution of Opiliones in Brazil can be considered suitable. However, while the harvestmen fauna of the southern Atlantic Forest is also well-known, several gaps remain and they are still far from complete, notably those in Paraná. Thus, investigations on regional assemblages focused on primary data are critical for promoting many key research fields such as taxonomic and phylogenetic studies, as well as encouraging conservation efforts. This study provides a comprehensive overview of the knowledge on diversity, distribution, and the history of Opiliones research from the state of Paraná. Knowledge gaps are identified and the background of taxonomic studies, highlighting the key contributors, is also discussed. A total of 1115 records were compiled, with 584 from Paraná for 118 species belonging to five families. This compilation allowed to identify 60 endemic species and 106 type localities (including invalid specific names) for the state. Despite being one of the three Brazilian states with the greatest diversity of harvestmen, this knowledge is concentrated in a small region in the First Plateau and is the result of the efforts of a few researchers and collectors over a few decades. To overcome these limitations further sampling is required in the state’s western region. This study is a very first step toward to achieve a comprehensive database of knowledge about Opiliones from one of the richest hotspots for these invertebrates in the world. We encourage similar approaches that consider the state of art for other research fields such behavior, ecology, and natural history in the state, as well as to other neotropical areas. suitable However wellknown, wellknown known, known well-known complete Thus studies contributors discussed 111 compiled 58 11 families 6 10 including names decades s world behavior ecology areas 5 1

abstract This study presents an innovative crude oil heating technology by introducing environmentally friendly solar energy into the petroleum industry. By integrating novel combination methods into traditional crude oil heating systems, a versatile and efficient crude oil heating system has been formed. The system was implemented in a refinery and its thermodynamic and economic performance was analyzed. The thermodynamic analysis, employing the exergy analysis method, reveals that among the considered parameters, compressor pressure ratio and Rankine cycle fluid flow rate exert the most significant influence on system efficiency. Overall, the system achieves energy efficiency, exergy efficiency, and waste heat recovery efficiency of 75.99%, 74.13%, and 31.21%, respectively. Within the system, solar collectors, TES tank, and compressor exhibit the highest exergy destruction rates, while pumps demonstrate the lowest exergy destruction rate. The economic analysis, using the annualized cost method, revealed that electricity prices have a significant impact on the economic performance of the system. The variation in system economic parameters is related to the annualized operating cost of the system. The system generates a net annual benefit of 0.591 million US$, with a 4.124-year investment return period. Moreover, Sensitivity analysis explores various factors affecting the crude oil heating system’s performance. industry systems formed analyzed method Overall 7599 75 99 75.99% 7413 74 13 74.13% 3121 31 21 31.21% respectively collectors tank rates 0591 0 591 0.59 US US$ 4.124year 4124year year 4.124 4 124 period Moreover s 759 7 9 75.99 741 1 74.13 312 3 2 31.21 059 59 0.5 124year 4124 4.12 12 75.9 74.1 31.2 05 5 0. 412 4.1 75. 74. 31. 41 4.

Abstract The collection of recyclable materials is an occupation with an increasing number of workers, who find in it a livelihood in a context of socioeconomic inequalities and unemployment. This article describes resistance strategies of women collectors who are part of an association in Northeast Brazil, in addition to describing how they managed health problems during the COVID-19 pandemic, especially regarding medicines. A quantitative and an ethnographic approach were used by collecting data on sociodemographic and medicines present in the homes of 13 participants and conducting participant observation and in-depth interviews. Amid the health crisis, the participants mentioned problems such as unemployment, gender relations, violence, and work stigmas. If, on the one hand, the pandemic has further increased vulnerability for certain population segments, on the other hand, it has enhanced collective resistance strategies. The collectors of the association organized to obtain various materials and benefits both for their headquarters and their neighborhood. We identified 58 units of medicines, prescribed and obtained mainly at the Basic Health Unit. Of these, 27.6% had action on the nervous system (analgesics, psycholeptics, and psychoanaleptics) and 17.2% on the cardiovascular system and on the alimentary tract and metabolism. The collectors developed self-attention practices with the medicines highlighting their central role in facing health problems. workers unemployment Brazil COVID19 COVID 19 COVID-1 1 indepth depth interviews crisis relations violence stigmas If hand segments neighborhood 5 Unit these 276 27 6 27.6 analgesics, analgesics (analgesics psycholeptics psychoanaleptics 172 17 2 17.2 metabolism selfattention self attention COVID1 COVID- 27. 17.

Abstract Epidendrum falcatum Lindl. is an endemic orchid of Mexico, with a discontinuous distribution in wild populations growing on limestone rocks. Anthropogenic activities and the demand of collectors have caused a decrease in the wild populations of this species. The objective of this work was to know the effect of two organic compounds on the in vitro propagation of E. falcatum. Seeds from an indehiscent capsule were grown on Murashige and Skoog (MS) medium modified to 50% of macronutrients and added with 100, 200 and 300 mL L-1 and g L-1 of coconut water or banana pulp. The organic compounds promoted germination of E. falcatum; the highest germination percentage was obtained with 100% coconut water. The control presented a greater number of leaves. However, treatments containing plantain significantly (p ≤ 0.01) stimulated the differentiation of the root system and aerial structures. This study represents a successful biotechnological method of in vitro propagation to obtain specimens of E. falcatum and thus counteract the exploitation of wild populations.

Resumen Epidendrum falcatum Lindl. es una orquídea endémica de México, con una distribución discontinua en poblaciones silvestres que crecen sobre rocas calizas. Las actividades antropogénicas y la demanda de coleccionistas han provocado una disminución en las poblaciones silvestres de esta especie. El objetivo de este trabajo fue conocer el efecto de dos compuestos orgánicos sobre la propagación in vitro de E. falcatum. Semillas provenientes de una cápsula indehiscente se cultivaron en medio Murashige y Skoog (MS) modificado a 50% de los macronutrientes y adicionado con 100, 200 y 300 mL L-1 y g L-1 de agua de coco o pulpa de plátano. Los compuestos orgánicos promovieron la germinación de E. falcatum; el mayor porcentaje de germinación se obtuvo con agua de coco a 100%. El control presentó mayor número de hojas. Sin embargo, los tratamientos que contenían plátano estimularon significativamente (p ≤ 0.05) la diferenciación del sistema radicular y de estructuras aéreas. Este estudio representa un método biotecnológico exitoso de propagación in vitro para la obtención de ejemplares de E. falcatum y así contrarrestar la explotación de las poblaciones silvestres.

ABSTRACT Lady Callcott was a British traveler who was active in criticism and art collecting. From her book Essays towards the history of painting, we can discuss the establishment of a scientific methodology for the history of art and understand the participation of women in art criticism. We argue that direct observation and description of collections, aspects observed in Callcott’s book, were resources used to attest to the authenticity of works acquired by Museums and private collectors. collecting painting collections Callcotts s collectors

RESUMO Lady Callcott foi uma viajante britânica que atuou na crítica e no colecionismo de arte. A partir de seu livro Essays towards the history of painting, podemos discutir o estabelecimento de uma metodologia científica para a história da arte e entender a participação das mulheres na crítica de arte. Defendemos que a observação direta e a descrição das coleções, aspectos observados no livro de Callcott, eram recursos usados para atestar a autenticidade das obras adquiridas por museus e colecionadores particulares. painting coleções particulares

RESUMO Trilhas ecológicas são propostas para auxiliar na Educação Ambiental, sobretudo em Unidades de Conservação, promovendo uma educação dinâmica e interação entre os visitantes e a natureza. A Floresta Nacional de Açu é uma Unidade de Conservação na Caatinga, localizada no município de Açu, Rio Grande do Norte. Aqui objetivamos desenvolver uma trilha de Educação Ambiental para visitantes, coletores de sementes, parataxonomistas e pesquisadores. Os indivíduos arbóreos foram marcados com placas de alumínio numeradas, identificadas e georreferenciadas. Foram identificadas 13 espécies de Leguminosae e marcados 34 indivíduos, além de 58 indivíduos pertencentes a 13 famílias distintas. Foram definidas três trilhas: (1) Trilha das Leguminosas; (2) Trilha da Catingueira-cinzenta e (3) trilha de imersão na Caatinga. Essas trilhas foram testadas pelos autores e visitantes nos dias 23-24 julho de 2022.

ABSTRACT Ecological trails are proposed to assist in environmental education programs, especially in reserves promoting a dynamic education and interaction with nature. The Floresta Nacional de Açu is a reserve of Caatinga dry forest, located in Açu, Rio Grande do Norte, Brazil. Here we aimed to develop an environmental education trail for visitors, seed collectors, parataxonomists and researchers. Adult tree individuals were marked with numbered aluminum tags, identified and georeferenced. Thirteen species of the Leguminosae were identified and 34 individuals were tagged, in addition to 58 individuals belonging to 13 different families. Three trails were defined: (1) Trail of Legumes; (2) Catingueira-cinzenta Trail; and (3) immersion trail in the Caatinga. These trails were tested by the authors and visitors between july 23-24, 2022. We conclude that the trails become an important tool to provide the protection of these environments and to increase perception of the local species. programs nature forest Norte Brazil collectors researchers tags georeferenced 3 tagged 5 1 families defined (1 Legumes 2 (2 Catingueiracinzenta Catingueira cinzenta (3 2324, 2324 23 24, 24 23-24 2022 ( 232 23-2 202 23- 20

Abstract By law, partnerships can be a corporate or non-corporate enterprises; cooperatives are non-corporate partnerships. Searching for better results in production, producers unite via cooperatives. Recyclable collectors are producers because they provide reusable raw materials. This activity is typically precarious, although environmentally relevant. Governed by a special law, the production and service cooperatives, within in the context of public policies and partnerships, are constituted for the purposes of formalization and income, removing waste collectors from the precarious work conditions. To verify the viability of this type of cooperative and the working relationship involved, Cooperagir was researched. From the data collected and using the SWOT matrix as an analysis tool, the positive and negative aspects of it were detected, including the work relationship. The strengths, opportunities, weaknesses, and threats were analyzed. It is concluded that the cooperative has the potential to evolve, however, there are threats that may make it infeasible. law noncorporate non enterprises materials relevant income conditions involved researched tool detected strengths opportunities weaknesses analyzed evolve however infeasible

Resumen Por ley, las sociedades pueden ser empresariales o no empresariales; las cooperativas son sociedades no empresariales. En la búsqueda de mejores resultados, los productores se unen a través de cooperativas. Los recolectores de materiales reciclables son productores que suministran materia prima reutilizable. Esa actividad es típicamente precarizada, aunque ambientalmente relevante. Regidas por una ley especial, las cooperativas de producción y servicios, insertadas en el contexto de políticas y asociaciones públicas, son constituidas con fines de formalización e ingresos, sacando al recolector del trabajo precario. Para conocer la viabilidad de ese tipo de cooperativa y la relación de trabajo que implica, se investigó la Cooperagir del municipio de Marechal Cândido Rondon/PR. A partir de los datos recogidos y utilizando la matriz FOFA como herramienta de análisis, se detectaron los aspectos positivos y negativos, incluyendo la relación de trabajo. En particular, se analizaron los puntos fuertes, las oportunidades, los puntos débiles y las amenazas. La conclusión es que la cooperativa tiene potencial para evolucionar, pero existen amenazas que podrían hacer inviable ese proceso. resultados reutilizable precarizada relevante especial servicios públicas ingresos precario implica RondonPR Rondon PR Rondon/PR análisis negativos particular fuertes oportunidades evolucionar proceso

Resumo Por lei, as sociedades podem ser empresariais ou não; as cooperativas são sociedades não empresariais. Na busca por melhores resultados, produtores se unem via cooperativa. Catadores de recicláveis são produtores que fornecem matéria-prima reaproveitável. Essa atividade é tipicamente precarizada, embora ambientalmente relevante. Regidas por lei especial, as cooperativas de produção e serviços, inseridas no contexto de políticas e parcerias públicas, são constituídas para fins de formalização e renda, tirando o catador do trabalho precário. Para averiguar a viabilidade desse tipo de cooperativa e a relação de trabalho envolvida, foi pesquisada a Cooperagir, no município de Marechal Cândido Rondon/PR. Dos dados levantados e usando a matriz FOFA como ferramenta de análise, detectaram-se os aspectos positivos e negativos, incluindo a relação de trabalho. Pontualmente, observaram-se as fortalezas, oportunidades, fraquezas e ameaças. Conclui-se que a cooperativa tem potencial para evoluir, entretanto, existem ameaças que podem inviabilizar esse processo. resultados matériaprima matéria prima reaproveitável precarizada relevante especial serviços públicas renda precário envolvida Cooperagir RondonPR Rondon PR Rondon/PR análise detectaramse detectaram negativos Pontualmente observaramse observaram fortalezas oportunidades Concluise Conclui evoluir entretanto processo
