A luta camponesa contada através da memória dos assentados do Lote Mãe Terra - Assentamento Horto Bela Vista em Iperó/SP
(Universidade Federal de São Carlos, 2022-07-08) Souza, Leticia Lauane de; Mariano, Neusa de Fátima; https://lattes.cnpq.br/8472989391950981; https://lattes.cnpq.br/5003743301847104
La lucha por la tierra es inherente la formación del territorio brasileño y el campesinado siendo uno de los representantes de esta lucha todos los días no podia dejar de se acerco. La clase campesina que tiene una moral para el trato con la tierra y que cree en el respeto a la naturaleza para construir sus relaciones, tiene memorias muy ricas que expresan resistencias en la construcción de sus territorios y territorialidades. De esta forma, pensar las memorias como factor de resistencia en la lucha campesina por el acceso a la tierra es dar voz a los grupos silenciados, valorando sus trayectorias en la construcción de sus territorios y territorialidad. Intentamos mostrar que las memorias pueden ser utilizadas en discusiones de Geografía y que la cuestión agraria en Brasil tiene mucho para ser discutido en diferentes perspectivas.
Valorização da lignina - um panorama geral
(Universidade Federal de São Carlos, 2022-07-08) Bonatti, Érika; Sitta, Elton; https://lattes.cnpq.br/4326476348284298; https://lattes.cnpq.br/4977333455603955
The urge to reduce greenhouse gas emissions, combined with the severe damage to the environment, such as the increase in the average world’s temperature, lead to incentives for research aimed at sustainable development. Consequently, the discussion about the transition from fossil resources to renewable raw materials and energy has become increasingly popular. Among the possible renewable sources, biomass has been gaining more and more prominence in recent years, due to its abundance and energy potential to replace petroleum derivatives. In particular, lignocellulosic biomass has advantages associated with the non-competition with the food sector, as well as opportunities for economic development and minimization of waste in agricultural areas. For this reason, lignocellulosic biomass has become the target for further studies and research. In this sense, although many advances have been made in terms of the valorization of cellulose and hemicellulose, the valorization of lignin is still a great challenge for researchers, due to its structural complexity and variable composition. The present work aims to highlight the state of the art in terms of fractionation, depolymerization and lignin valorization processes and the main renewable products that can be obtained through the improvement of the current conversion technologies.
Rotas digitalizadas: autonomia e controle no trabalho de entregadores por aplicativos em Araraquara - SP
(Universidade Federal de São Carlos, 2022-07-08) Jacobsem, Bruno Portari; Lima, Jacob Carlos; https://lattes.cnpq.br/9244132532446607; https://lattes.cnpq.br/9818262611142270
The insertion of digital technologies in business models in the last decades allowed the advance of the platformization process of several activities, granting new arrangements to the ambiguous relations between autonomy and control of work. Such is the case of delivery app workers – occupation that has been growing in Brazil since 2015 alongside the spread of "technology companies" mediating delivery services. Whereas control – now executed by diffuse and unknowable algorithms – appears to subsume to the possibilities of agency propounded by companies, autonomy is attached to the generalization of the entrepreneurial discourse and – formally magnified – it masks relations of subordination which may become evident throughout daily experiences of these workers distanced from a regulatory perspective of work. The objective of this dissertation was to characterize the relationship between both dimensions – autonomy and control – amidst working conditions of delivery app workers. The research was conducted with workers of this segment on four different platforms operating in the city of Araraquara (SP), whose reports allowed us to situate the reality of an autonomous "riding" life into the current context of exploitation and subordination of labor to capital.
