Feira de saúde do curso de medicina da UFRR: uma aproximação com a comunidade

Abstract: As Feiras de Saude do curso de Medicina da Universidade Federal de Roraima (UFRR) buscam informar e sensibilizar a comunidade quanto a melhoria da qualidade de vida a partir da prevencao, orientando para a mudanca de habitos de vida e diagnosticando precocemente as doencas a fim de trata-las e cura-las. Alem disso, a UFRR busca se aproximar da populacao boa-vistense por meio desse trabalho de extensao universitaria e da realizacao de um servico de utilidade publica de grande relevância academica e comunitaria. A diversidade das licoes aprendidas, registradas como relatos de experiencias ou como estudos, pelo conjunto de profissionais, gestores, pesquisadores e academicos constituiu um importante estimulo ao debate acerca dos limites e possibilidades do Programa Saude da Familia e da interacao do academico na comunidade.

Multicritical behavior of the two-dimensional transverse Ising metamagnet in a longitudinal magnetic field

Abstract: Magnetic phenomena of the two-dimensional anisotropic antiferromagnetic Ising model in both uniform longitudinal ( H ) and uniform transverse ( Ω ) magnetic fields are studied by employing a mean-field variational approach based on Bogoliubov inequality for the free energy. The phase diagrams in the magnetic fields and temperature ( T ) planes, namely H − T and Ω − T , are analyzed on an anisotropic square lattice for some values of the ratio α = J y / J x , where J x and J y are, respectively, the exchange interactions along the x and y directions. Depending on the range of the Hamiltonian parameters, one has only second-order transition lines, only first-order transition lines, or both first- and second-order transition lines with the presence of tricritical points. In addition, the corresponding phase diagrams are free from any reentrant behavior.

Características das situações estressantes em gestores universitários no contexto do trabalho

Abstract: O estresse constitui um fenomeno complexo que necessita ser compreendido por meio de diferentes contextos. E considerado positivo e necessario para a sobrevivencia, e negativo quando sua exposicao ocorre de maneira constante e incontrolavel. O objetivo deste estudo foi analisar as situacoes estressantes vivenciadas por vinte e um gestores pertencentes a duas universidades publicas do Sul do Pais. Foi utilizado um roteiro de entrevista com perguntas semi-estruturadas. A analise dos dados foi feita por meio da construcao de categorias, a partir das verbalizacoes dos participantes. Os gestores indicaram vivenciar situacoes estressantes, demonstrando ser o estresse uma condicao inevitavel. Essas situacoes foram relacionadas a lidar com pessoas; alta demanda de trabalho; processos burocraticos; caracteristicas pessoais, entre outras. Nessas Universidades nao ha preparacao para ser gestor. Os gestores indicaram a aquisicao de experiencia profissional durante o exercicio do cargo de gestao e em cargos anteriores. Analisaram que maturidade e tempo de servico tambem auxiliam no exercicio da funcao.

Natural Remedies for Animal Health in Latin America

Abstract: Since immemorial times, humans have been using plants and animals as medicinal sources according to the benefit that these resources offered. Latin America has a population whose culture is the result of a combination of different ethnic groups and has contributed to it becoming one of the most culturally diverse regions in the world. Similarly, the great abundance of natural resources that can be extracted from a rich biodiversity favors their use by traditional populations that depend on such resources to guarantee the health of their animals through a folk medicine practice known as ethnoveterinary medicine, which passed on through the generations. This chapter provides a compilation of the richness of species of animals and plants cited in the literature as being used for ethnoveterinary purposes in Latin America. The results show a plethora of biological species (364 species of plants and 61 animal species) for the treatment of diseases and sicknesses of livestock and herds in this area. The families of medicinal plants that were most frequently reported were Fabaceae and Asteraceae, whereas mammals were the animal group most reported as a source of drugs for ethnoveterinary treatments, followed by insects. These data reflect the existence of broad knowledge regarding the use of natural resources in traditional veterinary medicine in Latin America, a practice that has persisted over time.

Curvas de crescimento de plantas de mandioca submetidas a doses de potássio

Abstract: Potassium is considered nutrient extracted over cassava. Thus, its low availability in the soil affects plant growth, reflecting the expansion of cultivated area and productivity of crops potassium deficient. The objective of this present work was to establish growth curves of plants cassava cultivar Aciolina submitted to five doses of potassium, grown in Roraima savannah environment. The experimental design was in blocks at random in scheme of split plots, with four replications. Five doses of potassium (0, 30, 60, 120 and 240 kg ha-1 K2O) were randomized in the plots and evaluation times (150, 210, 270 and 360 days after planting - DAP) in the subplots. The variables evaluated: stem diameter, height of first ramification, plant height and leaf characteristics. The height growth of cv. Aciolina occurred at all levels of fertilization with potash, indicating that the low content of K restricts the growth of the plant height. The components of growth of the cassava plant, stem diameter, height of the first ramification and plant height are positively affected by increasing doses of potassium up to 240 kg ha-1. The width of the sheet, the number of lobes and the relationship between the length of the central lobe width of the central lobe are not affected by the potassium.
