Adubação foliar na suplementação nutricional de cultivares de abacaxizeiro micropropagadas

Abstract: Although there are already available pineapple cultivars resistant to fusariosis, Brazilian production is based on the cultivar Perola, susceptible to fusariosis. Studies with these resistant cultivars should prioritize the fulfillment of nutritional requirements, so that they express their productive potential and become viable options for producers. The objective of this study was to study the effects of foliar fertilizer compositions on the growth and yield of five micropropagated pineapple cultivars. The study was started in a greenhouse and at 210 days after transplanting, the seedlings were transferred to field conditions. The experimental design was in randomized blocks, in subdivided plots with three factors and four replications. The combination of the five pineapple cultivars (BRS Ajuba, IAC Fantastico, BRS Imperial, Perola and BRS Vitoria) and three leaf fertilizer compositions (NK, NPK and NPK + micronutrients) were randomized in plots and six evaluation periods consisted of subplots. Agronomic attributes were analyzed at the time of evaluation. The results obtained were subjected to analysis of variance by the F test. The Scott-Knott test was used for comparisons between cultivars and fertilization, and regression for the seasons, using the SISVAR program. Regardless of fertilization, cv. IAC Fantastico stood out in the majority of the evaluated characters, being superior to cv. Perola, considered standard. The NK formula shows to be the best option for use as leaf fertilizer in the pineapple crop. The cultivar IAC Fantastico has good vegetative and productive characteristics, having the potential to be a viable option for cultivation in the state of Roraima

Aprendizagem docente na formação inicial de acadêmicas do Curso de Pedagogia

Abstract: This study is linked to the research project Learning of teaching: training processes of students and Higher Education educators . It aimed to understand the process of learning of teaching with undergraduate students in initial training. We used theoretical and methodological assumptions from the studies of Connelly and Clandinin; Imbernon; Libâneo and Pimenta; Pimenta; and Novoa, which collaborated with the construction and analysis of the research findings. The methodology adopted was qualitative, considering sociocultural narrative features from the narratives of undergraduates in initial training. The analysis category produced was the learning of teaching, which was consisted of four guiding dimensions: the awareness, the incompleteness, the relation between theory and practice, and the study activity. These dimensions allowed us the comprehension of significant recurrences in the formative path, which are involved in the undergraduates learning of teaching. Thus, we acknowledge the complexity of learning of teaching and that the learning in initial training is built through the awareness, the incompleteness, the search for the relation between theory and practice and the study activity, which are dimensions that characterize this process.

Feminicídio e a pandemia da covid-19: perícia criminal e a tipificação do crime de violência de gênero no direito

Abstract: O presente estudo aborda a tematica da pandemia da COVID-19 e a violencia domestica contra as mulheres, refletindo sobre a importância da pericia criminal e a tipificacao do crime de violencia de genero, tendo como objetivo principal a sua analise no direito, podendo contribuir para o combate da violencia domestica e o feminicidio, bem como mostrar que as medidas de isolamentos e sanitarizacao contribuiram para o aumento dos casos de feminicidios no Brasil. A metodologia da pesquisa parte de uma revisao de literatura caracterizado pela pesquisa bibliografia e documental de cunho descritivo sob uma abordagem sistemica e qualitativa a partir da analise de conteudo. A pesquisa parte de um estudo bibliografico, que do ponto de vista dos procedimentos tecnicos pode ser elaborada a partir de material ja publicado, constituido principalmente de livros, artigos de periodicos, e atualmente com material disponibilizado na Internet. Sendo assim, o presente estudo busca contribuir com o meio cientifico e com a sociedade civil, no sentido de informar e esclarecer os direitos e a necessidade de medidas que venham fortalecer a legislacao no que tange a protecao da mulher e o combate a violencia domestica e o feminicidios.

Geograficidade e vulnerabilidades na Amazônia ribeirinha, comunidade Xixuaú, Roraima, Brasil

Abstract: The text analyzes the geography and the perceived vulnerabilities in the community of Xixuau, located on the banks of the Jauaperi River, in the Lower Rio Branco region, in Roraima, in the extreme north of the Amazon. For this, it seeks in field research and in the bibliography of phenomenological affiliation, to understand the idea of ”‹”‹place, using the residents' narratives about their way of life and the historical relationship of this riverside being with the lived space. It is noted that the Amazon riverside has a particular multidimensional cosmology of the environment, demonstrating that it is possible to adapt to verticalities of economic interest, but at the same time, resist such external interventions, if necessary, in the defense of the place

TERRITÓRIOS e TERRAS INDÍGENAS: UMA BREVE REFLEXÃO A PARTIR DA GEOGRAFIA

Abstract: Os povos indigenas tem em seu historico deslocamentos e a formacao de novos territorios e os motivos para essa dinâmica sao diversos. Com a chegada do Estado Nacional e sua logica capitalista, essa dinâmica tem se alterado com a demarcacao de terras indigenas, principalmente na Amazonia, destinando aos povos um espaco para sua sobrevivencia e reproducao fisica e cultural, como definido no texto constitucional brasileiro. Trazemos aqui uma reflexao e uma colaboracao sobre o conceito de terra indigena e territorio indigena, considerando uma experiencia profissional que se depara constantemente com a duvida de como se referir aos atuais espacos destinados a esses povos: terra indigena ou territorio indigena. Discutimos que, em um momento anterior a expansao capitalista, os povos indigenas se deslocavam pelo espaco e se apropriavam de novas areas, constituindo novos territorios e areas de controle. No seculo XX, o Estado define que algumas areas devem ser demarcadas, criando as terras indigenas. Essas acoes indicam um avanco para esses povos, porem, essas terras sao, ao mesmo tempo, uma garantia a reproducao do grupo e uma limitacao no que se refere ao controle do espaco, tanto no uso dos recursos naturais quanto na disposicao da propria terra, que e controlada pelo Estado e nao pelas comunidades.
