ABSTRACT
Resumo: Este artigo reflete sobre a singularidade das relações entre mulheres rurais e os cães que com elas constituem um relacionamento interespecífico. Objetiva contar sobre práticas que foram emergindo ao longo de uma pesquisa quando passamos a encarar seriamente a agência de animais a partir do cotidiano de uma agricultora pesquisadora alinhada à agroecologia familiar. Focalizamos os cães de passagem sem raça definida e que vão e vêm livremente entre as cercas que delimitam as propriedades rurais. Em diálogo com Donna Haraway, Anna Tsing e Vinciane Despret, apresentamos pistas para uma pesquisa multiespécie que opera por meio de causos. A pesquisa multiespécie nos convida a reflexões sobre práticas anticapitalistas que germinam na agroecologia, a nos determos no trabalho das mulheres agricultoras e dos cães na sua potência de autogoverno e de criarmos formas de cooperação multiespecíficas com alteridades significativas no projeto moderno-colonizador.
Resumen: Este artículo reflexiona sobre la singularidad de las relaciones entre las mujeres rurales y los perros que constituyen una relación interespecífica con ellas. El objetivo es relatar las prácticas que surgieron a lo largo de una investigación cuando empezamos a considerar seriamente la agencia animal basada en la vida diária de una agricultora investigadora alineada con la agroecología familiar. Centramonos en perros mestizos que van y vienen libremente entre las vallas que delimitan las propiedades rurales. En diálogo con Donna Haraway, Anna Tsing y Vinciane Despret, presentamos pistas para una investigación multiespecie que opera a través de historias. La investigación multiespecie nos invita a reflexionar sobre las prácticas anticapitalistas que germinan en la agroecología, a centrarnos en el trabajo de las campesinas y los perros en su poder de autogobierno y a crear formas de cooperación multiespecífica con alteridades significativas en el proyecto moderno-colonizador.
Abstract: This article reflects on the uniqueness of the relationships between rural women and the dogs that constitute an interspecific relationship with them. It aims to tell about practices that emerged throughout research when we began to seriously consider the animal agency based on the daily life of a farmer researcher aligned with family agroecology. We focus on mixed breed dogs that come and go freely between the fences that delimit rural properties. In dialogue with Donna Haraway, Anna Tsing and Vinciane Despret, we present clues for multispecies research that operates through stories. Multispecies research invites us to reflect on anti-capitalist practices that germinate in agroecology, to focus on the work of women farmers and dogs in their power of self-government and to create forms of multispecific cooperation with significant alterities in the modern-colonizing project.
ABSTRACT
Polymeric nanocomposites are novel materials of huge interest owing to their favourable cost/performance ratio with low amount of nanofillers, improved thermal resistance, flame retardancy and mechanical properties in relation to their matrices. In this work, composites based on post-industrial waste or primary recycled poly(butylene terephthalate) and 5 wt.% of organic modified montmorillonite clays were melt compounded using a twin-screw extruder. A 2(2) factorial experimental design was used to study the compounding and processing variables: Organic modified montmorillonite with one or two hydrogenated tallow (initial basal spacing) and screw speed of the extruder. X-ray diffraction and transmission electron microscopy suggest that a partial exfoliation of the organoclay in the recycled poly(butylene terephthalate) matrix was achieved for organic modified montmorillonite with lower initial basal spacing. On the other hand, formulations containing organic modified montmorillonite with higher initial basal spacing showed only intercalated structure. The recycled poly(butylene terephthalate)-organic modified montmorillonite nanocomposites did not drip flaming material during burning tests. Storage of dynamic-mechanical, tensile and flexural moduli of the recycled poly(butylene terephthalate)-organic modified montmorillonite were improved when compared with both virgin and recycled poly(butylene terephthalate)s, mainly for nanocomposites formulated at a lower initial basal spacing organoclay. This could be related to a better diffusion of polymer into organic modified montmorillonite layers compared with the higher initial basal spacing organoclay. The improvements on the physical properties of recycled poly(butylene terephthalate) showed the feasibility to add value to primary recycled engineering thermoplastics with a very small amount of organic modified montmorillonite.
