COMPETITIVIDADE DAS EXPORTAÇÕES BRASILEIRAS DA CARNE DE FRANGO FRENTE ÀS EXPORTAÇÕES AMERICANAS
This paper aims to analyze the evolution of the Brazilian exports of chicken meat, highlighting the competitiveness of Brazilian exports compared to American exports from 1997 to 2017. This is a descriptive exploratory research with a qualitative and quantitative approach. The evolution of exports was analyzed through the Brazilian and international economic context, while the competitiveness of exports was estimated using the Index of Comparative Advantage Revealed. The results showed that Brazil has a comparative advantage over the United States in all years, which corroborates the fact that chicken meat is one of the main products on the Brazilian export basket and not be one of them on the American export basket.Este artigo tem por objetivo analisar a evolução das exportações brasileiras da carne de frango, destacando a competitividade delas em relação às exportações americanas de 1997 a 2017.

An approach to highly polluted wastewater management for zero liquid discharge: The case of landfill leachate
This work aims to bring the treatment of highly polluted wastewater to the concept of zero liquid discharge, using landfill leachate as a representative example. Achieving this goal involves removing pollution due to organic matter and/or heavy metals and recovering the nutrients contained in the effluent. Thus, the sequential combination of thermally activated persulfate and the Fenton reagent is proposed to eliminate the high concentration of organic matter. This avoids the need of pH adjustment to meet the Fenton process operation criteria and minimizes the amount of persulfate and, consequently, the conductivity in the treated effluent. Furthermore, this solution is particularly attractive in systems with excess energy, such as urban solid waste facilities where biogas is generated. Nutrient recovery (N in the case of landfill leachate) is carried out through precipitation in the form of struvite. Finally, if necessary, a further nanofiltration stage is proposed to minimize the conductivity of the treated effluent, making it suitable for on-site use. Under the optimized operating conditions (Flow rate: 0.5 L h−1, residence time 60 minutes, 0.3 and 0.7 times the stoichiometric amount of persulfate (12 g/g COD0) and H2O2 (2.12/g COD0), respectively, a H2O2/Fe2+ ratio of 50/1 and 85°C), a 90% removal of COD is achieved, along with 99% and 95% recovery of the nitrogen content in the effluent and reclaimed water, respectively, confirming the feasibility of this solution as an approach to a more sustainable waste managementPID2019–106884GB-I0
“A escuta sensível para além das grades”: oficinas com mulheres aprisionadas
O presente artigo objetiva apresentar atividades socioeducacionais e políticas desenvolvidas com mulheres em condição de privação de liberdade em uma unidade prisional de um município de médio porte do sul de Mato Grosso. O posicionamento teórico-metodológico esquizoanalista apoia a tríade teoria-prática-supervisão por meio de “rodas de conversas” executadas por discentes de um curso de Psicologia. Concluímos que as atividades desenvolvidas produzem condições para a expressão de subjetividades normatizadas, mas também produzem maneiras singulares de condução de suas existências, estabelecendo uma conexão polifônica aberta e coletiva, baseada em respeito, compreensão e problematizações importantes sobre como superar o processo de institucionalização e construir um projeto de vida ao retornarem ao convívio social em meio aberto
Isolation and phenotypic characterization of rhizobia that nodulate cowpea in the Cerrado in Tocantins State, Brazil
Em função das características nutricionais e de rusticidade, o feijão caupi tornou-se importante fonte de proteína nas regiões Norte e Nordeste do Brasil. O feijão caupi se beneficiada fixação biológica do nitrogênio (FBN) e pode receber parte do nitrogênio necessário para a cultura via simbiose, o que reduz os custos de produção. Com o objetivo de contribuir com a otimização do processo de FBN na cultura do feijão caupi (Vigna unguiculata (L) Walp) no cerrado do Tocantins, através da efetividade de populações e diversidade de isolados de rizóbio obtidos em sete áreas com e sem cultivos agrícolas, foram realizados isolamento e caracterização fenotípicas (pH do meio, tempo de crescimento, características das colônias e de muco). Foram obtidos 72 isolados de rizóbio e avaliados em um dendrograma onde mostraram uma grande diversidade com a formação de 18 grupos e cinco grandes grupos com similaridade de 70%. O estudo das características fisiológicas e morfológicas revela uma diversidade bastante ampla dos isolados de rizóbio e costuma estar relacionado com estudos em nível de DNA.Depending on the nutritional characteristics and hardiness, the cowpea has become an important source of protein in North and Northeast regions of Brazil. The cowpea benefits from biological nitrogen fixation (BNF) and may receive part of the nitrogen needed for culture via symbiosis, which reduces production costs. Aiming to contribute to the optimization of the BNF in the culture of cowpea (Vigna unguiculata (L) Walp) in the cerrado of Tocantins, through the effectiveness of populations and diversity of rhizobia obtained in seven areas with and without crops , phenotypic isolation and characterization were performed (pH, time of growth characteristics of the colonies and mucus). We obtained 72 rhizobia and evaluated in a dendrogram showed a great diversity, with the formation of 18 groups and the five large groups with 70% similarity. The study of morphological and physiological characteristics reveals a fairly wide diversity of rhizobia and is usually related to studies at the DNA level

RECYCLING TO RECREATE: ENVIRONMENTAL EDUCATION BY MAKING TOYS WITH RECYCLABLE MATERIALS IN BREVES, MARAJÓ ISLAND, BRAZIL
ABSTRACT: The excessive production of garbage on the planet is a consequence of actions due to the problem of unbridled consumerism and the lack of awareness on the part of the population. The reuse of recyclable materials can be a concrete and practical alternative to develop the process of environmental awareness in children and it is essential to introduce activities to reuse recyclable materials. Thus, the objective of this work was to make toys through recyclable materials, providing knowledge and awareness for the preservation of the environment, around IFPA, Campus Breves. This work was carried out at the Federal Institute of Pará, Campus Breves with the surrounding children. The workshops included teaching children how to make toys and then playing with toys made by themselves. Among the materials used are pet bottles, milk cans, clothes line, glue, scissors, EVA, being made from the back and forth of PET bottle, door shanks and can foot. The analysis of the results was carried out observing the participation, involvement and interest of the children and if they were able to produce their own toy, besides verifying if the didactic resources used aroused the curiosity of the children. A questionnaire was also carried out with the students involved in the project in order to evaluate the importance of the project in its professional growth. As a result, the project worked as an instrument capable of interfering in the teaching-learning process in order to educate children who are aware and able to integrate better with society, in addition to understanding that the importance of recycling and preservation environment must be a continuous process. The presentation of the themes mentioned and the possibility of constructing the toys themselves aroused children's curiosity and tended to bear fruit. It can be concluded that in addition to making children aware, it was possible to manufacture toys from low-cost materials, which is an action with an environmental educational principle. In addition, students' satisfaction with participating in community workshops was noted.
