Mineral Composition of \u3cem\u3eBrachiaria brizantha\u3c/em\u3e cv. MG5 Irrigated and Non-Irrigated Subjected to Grazing
Brachiaria brizantha cv. MG5 is an important component of pastures in Brazil. Past studies (Corsi and Marta Jr. (1998), Maya (2003)) have shown significant pasture and animal production increases can be obtained through irrigation and associated grazing management. Such systems can significantly increase economic viability of production systems based on these pastures (Cedeño 2003). However, past studies have not measured possible differences in mineral composition of such pastures throughout the year with and without irrigation. Such differences, if present, may have implication for animal productivity.
This study had the objective of evaluating the mineral composition of Brachiaria brizantha cv. MG5 with and without irrigation in different times of the year
Effects of Irrigation and Season on Performance of Grazed Pastures of \u3cem\u3eBrachiaria brizantha\u3c/em\u3e cv. MG5
In Brazil, livestock production is based primarily on systems with continuously grazed natural or cultivated pastures (FAO 2009). Intensifying animal breeding, handling and knowledge strategies is necessary to obtain improvements in production indices for economically feasible and sustainable grazing systems (Cedeño et al. 2003). Beef cattle breeding on irrigated pasture, like all forms of intensive grazing, requires the use of forage species with high potential for production and quality, and Brachiaria brizantha cv. MG5 is considered a good option. This study aimed to evaluate the effects of irrigation on the performance of B. brizantha cv. MG5 grazed rotationally by beef cattle at different times of the year
Neutrino oscillations from relativistic flavor currents
By resorting to recent results on the relativistic currents for mixed
(flavor) fields, we calculate a space-time dependent neutrino oscillation
formula in Quantum Field Theory. Our formulation provides an alternative to
existing approaches for the derivation of space dependent oscillation formulas
and it also accounts for the corrections due to the non-trivial nature of the
flavor vacuum. By exploring different limits of our formula, we recover already
known results. We study in detail the case of one-dimensional propagation with
gaussian wavepackets both in the relativistic and in the non-relativistic
regions: in the last case, numerical evaluations of our result show significant
deviations from the standard formula.Comment: 16 pages, 4 figures, RevTe

EXPERIÊNCIAS PEDAGÓGICAS, FORMATIVAS E DIALÓGICAS DO PIP FILO
O presente texto é um relato da experiência do Projeto de Inovação Pedagógica do curso de Filosofia (PIP FILO) da Universidade Federal do Tocantins. O projeto teve início em junho de 2021 e sua finalização em dezembro do mesmo ano. O intuito do projeto foi proporcionar a utilização de novas ferramentas digitais para as práticas pedagógicas de ensino. O conteúdo aqui descrito faz parte de um curso de formação digital promovido pelo PIP FILO e que contou com a colaboração do curso de Teatro e do Residência Pedagógica. O projeto se desenvolveu junto com um Tutor e com Monitores de Inovação Pedagógica (MIPs) por dois caminhos; (1) a utilização de ferramentas digitais como prática pedagógica por meio de cursos, oficinas, lives e palestras, (2) a realização de uma chuva de ideias que foi organizada no mindmeister, no qual restringindo-nos à pesquisa sobre fakes news atribuídas a Paulo Freire e que acrescentamos a essa pesquisa uma dose de humor dos cínicos gregos
