Persuasão ou performance: as estratégias comunicacionais para transformar o rúgbi em paixão nacional

This paper analyzes the communication strategy of the Brazilian Rugby Confederation in the promotion of sport in the country, with three television campaigns developed since 2010 together with manufacturer Topper. One of the goals of the organization is to make the sport better known among the Brazilian public, with a view to inclusion of rugby in the Olympics in Rio de Janeiro in 2016. Very popular in countries colonized by Britain, the sport still has little visibility in the national sports scene, something to be transformed in organizational communication and advertising.

Uso inadequado de áreas de preservação permanente

O grande desafio da população mundial é a conservação ambiental, pois as Áreas de Preservação Permanentes, que têm papel vital dentro de uma microbacia, por serem responsáveis pela manutenção, preservação e conservação dos ecossistemas ali existentes. O presente trabalho visou analisar os conflitos de uso do solo em áreas de preservação permanentes (APPs) da microbacia do Alto Capivara - Botucatu (SP) através do uso de Sistema de Informações Geográficas e de imagem de satélite digital. A área com 4551,19ha, situa-se entre as coordenadas geográficas: 22o 51’ 57” a 22o 57’ 55” de latitude S e 48o 21’ 58” a 48o 26’ 38” de longitude WGR. O mapa de uso do solo de 2006 foi obtido a partir da classificação supervisionada em imagem de satélite digital de 23/10/2006. Na identificação digital dos alvos foram utilizadas as chaves de interpretação para imagens e as áreas foram determinadas através do software SIG – IDRISI. Os conflitos de uso nas áreas de preservação permanente foram analisados ao longo da rede de drenagem e das nascentes, conforme itens dos artigos 2º e 3º da Resolução nº 303 do CONAMA. A área de APP discriminada ao longo da rede de drenagem foi de 416,5ha (9,15%) . No entanto, 201,15ha da área de APP está ocupada com pastagem (48,3%), reflorestamento (1,23%) e 0,48% por área urbana de forma inadequada (conflito). Portanto, quase 50% de área de APP vem sendo parcialmente utilizada adequadamente.

Produção de repolho em função da idade das mudas

The seedling transplanting ages is a factor of great importance because it can affect the quality and yield of plants if the volume of the cell is not compatible with the phenology of seedlings at time of transplantation. The experiment was conducted at São Manuel Experimental farm, Faculdade de Ciências Agronômicas da UNESP, from March to August, 2009. The objective of this study was to evaluate the effect of seedling age on cabbage production, hybrid Kenzan. The seedlings were grown in polystyrene trays containing 128 cells. Seedings were done every four days and contained the following treatments: 37, 41, 45, 49 and 53 days after sowing (DAS). The experimental design was randomized blocks, with five replications. On transplantation’s day (11/05/2009), the number of leaves, fresh and dry weight and height, were evaluated to the characterization of seedlings. It was observed that the seedling age had no influence on traits at harvest: number of leaves inside and outside of “head”, fresh weight of shoot and “head”, dry mass of shoot and “head” and length of “heart”.

Controle químico em pós-emergência de espécies de Brachiaria em três estádios vegetativos

The aim of this study was to correlate the chemical control efficacy in post-emergence of Brachiaria decumbens Stapf. (signal grass) and Brachiaria plantaginea Hitchc. (alexandergrass) through ACCase-inhibitor enzyme herbicide application in function of the stage of development of the plant in order to contribute to the chemical management of these weed species. B. decumbens and B. plantaginea were sown in plastic pots filled with soil and kept in a greenhouse. For chemical control evaluation, the following herbicides were tested (g ha-1): fluazifop-p-butyl at 150, haloxyfop-methyl at 50, and sethoxydim at 230. The herbicides were applied in all three plant development phases: stage 1 (plants presenting 4-6 leaves at 15 days after emergence), stage 2 (plants presenting 3-4 tillers at 23 days after emergence), and stage 3 (adult plants in the beginning of flowering at 48 days after emergence). Evaluations were done at 4, 7, 10, 14, 17, 21, 24, and 28 days after herbicide application. The developmental stage of the two Brachiaria species was instrumental in the efficiency of the control provided by different herbicides. Sethoxydim was the most efficient herbicide in controlling Brachiaria species in the three evaluated development stages.
