Caracterização do Xote e do Baião dançados no interior do Estado de São Paulo

Ballroom dance and Forro are part of Brazilian culture, and Xote and Baiao are part of Forro. The aim of this study was to diagramate the dances Xote and Baiao they are danced inside São Paulo State and to describe rhythmly these movements. It was observed and filmed several college couples dancing Xote and Baiao for analysis and description of the movements of the dances, by a discursive way and by diagrams. It was identified two basic structures ("Lateral Basic Step" and "Forward and Back Basic Step"), and variation steps "Open" and "Change of places with Turn", very used by couples.

Desenvolvimento de equipamentos para o mapeamento de áreas infestadas por macrófitas aquáticas imersas

Foi desenvolvido um conjunto de equipamentos com o objetivo de mapear as áreas infestadas por macrófitas aquáticas, auxiliando operações de manejo mecânico, as quais são realizadas por uma colhedora desenvolvida especificamente para essa finalidade. O conjunto de equipamentos foi constituído por um GPS com programa de correção diferencial, acoplado a um palmtop, um sistema com dois teclados ligados em dataloggers e um transdutor de deslocamento linear LT. O GPS, através do palmtop, proporcionava o mapeamento da área de deslocamento, auxiliando o operador na movimentação da máquina, otimizando a operação e evitando, dessa forma, a sobreposição das faixas de coleta na área a ser manejada. Um dos teclados monitorava a movimentação e operação da colhedora, além da presença de obstáculos, como tocos e bancos de areia, enquanto o outro gerava dados sobre a presença de determinada espécie de planta, como E. densa, E. najas e C. demersum, além do nível de infestação destas plantas. O transdutor, instalado na plataforma frontal da colhedora, se movimentava linearmente, gerando informações sobre a profundidade da coleta realizada. Dessa forma, pôde-se observar que o desenvolvimento desse conjunto de equipamentos foi de grande utilidade e auxiliou a operação de controle mecânico de áreas infestadas por macrófitas aquáticas imersas, possibilitando, assim, o planejamento de operações de manejo e controle subseqüentes.

Estimation and evaluation of dynamic properties as indicators of changes on soil structure in sugarcane fields of São Paulo State - Brazil

The indiscriminate management and use of soils without moisture control has changed the structure of it due to the increment of the traffic by agricultural machines through the years, causing in consequence, a soil compaction and yield reduction in the areas of intensive traffic. The purpose of this work was to estimate and to evaluate the performance of preconsolidation pressure of the soil and shear stress as indicators of changes on soil structure in fields cropped with sugarcane, as well as the impact of management processes in an Eutrorthox soil structure located in São Paulo State. The experimental field was located in Piracicaba's rural area (São Paulo State, Brazil) and has been cropped with sugarcane, in the second harvest cycle. The soil was classified by Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) [Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 1999. Centro Nacional de Pesquisa de Solos. Sistema Brasileiro de Classificao de Solos, Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), Brasilia, 412 pp.] as an Eutrorthox. Undisturbed samples were collected and georeferenced in a grid of 60 m x 60 m from two depths: 0-0.10 m (superficial layer - SL) and in the layer of greatest mechanical resistance (LGMR), previously identified by cone index (CI). The investigated variables were pressure preconsolidation (sigma(p)), apparent cohesion (c) and internal friction angle (phi). The conclusions from the results were that the SLSC was predicted satisfactorily from up as a function of soil moisture; thus, decisions about machinery size and loading (contact pressures) can be taken. Apparent cohesion (c), internal friction angle (phi) and the Coulomb equation were significantly altered by traffic intensity. The sigma(p), c and phi maps were shown to be important tools to localize and visualize soil compaction and mechanical resistance zones. They constitute a valuable resource to evaluate the traffic impact in areas cropped with sugarcane in State of São Paulo, Brazil. (C) 2008 Elsevier B.V. All rights reserved.

Modelo de programação linear para seleção de pulverizadores agrícolas de barras

A seleção de pulverizadores agrícolas que se adaptem às necessidades da propriedade, é um processo trabalhoso, sendo uma das etapas mais importantes dentro do processo produtivo. O objetivo do presente trabalho foi o de desenvolver e utilizar um modelo de programação linear para auxiliar na seleção de pulverizadores agrícolas de barras, baseado no menor custo horário do equipamento. Foram utilizadas as informações técnicas referentes a 20 modelos de pulverizadores disponíveis no mercado, sendo quatro autopropelidos, oito de arrasto e oito do tipo montado. A análise de sensibilidade dos componentes dos custos operacionais mostrou que as taxas de reparo e depreciação foram os fatores que mais interferiram na variação do custo horário do conjunto trator-pulverizador. O modelo matemático desenvolvido facilitou a realização da análise de sensibilidade que foi processada em um tempo muito pequeno.

Efeito dos níveis de energia da ração sobre o desempenho e teor de gordura na carcaça de frangos de corte

It was studied the effect of energy levels in the diet, obtained from vegetal oil inclusion, on the performance, diet cost per kilogram of broiler and fat content of the carcass, There were used 4,800 broiler chicks, 2,400 males and 2,400 females, and they were distributed in six treatment (energy levels in kcal ME/kg of diet) in three different phases: start diet from one to 20 days of age: A - 2930, B - 2980, C - 3030, D - 3080, E - 3130, F - 3180, growth diet from 21 to 40 days: A - 2980, B - 3030, C - 3050, D - 3130, E - 3150, F - 3230, finishing diet from 41 to 45 days of age: A - 3030, B - 3080, C - 3130,, D - 3180, E - 3230, F - 3280. The protein content was 22, 20 and 18% in each phase, respectively, There were evaluated the feed intake, energy intake, protein intake, weight gain, feed conversion mortality, diet cost per kg/bw. Sixty broilers were slaughtered, five males and five females per treatment, randomly chosen to determine the carcass composition considering the dry matter content, lipids content and protein content, total fat in carcass and fat per kilogram of broiler. The data were submitted to variance analysis and the means were compared using SNK. The broilers fed with medium and low levels of dietary energy showed the highest weight gain. At energy levels of the treatment D in the three phases, the lowest cost per kilogram of broiler was obtained. The females presented the highest fat content per kilogram of broiler produced.

Morphological caste differences and non-sterility of workers in Brachygastra augusti (Hymenoptera, Vespidae, Epiponini), a neotropical swarm-founding wasp

Morphological caste differences and ovary conditions were analyzed in four colonies of Brachygastra augusti collected in different stages of the colony cycle. Differences between castes are distinct suggesting pre-imaginal determination. Many intermediates (non-inseminated ovary-developed females) were found. Because these intermediate females were morphologically similar to workers, it is suggested that they are young ovary-developed workers. Because there is a more evident overlap between queens and workers in the colony in pre-emergence of workers stage, and in three colonies in latter stages, especially in worker-production colonies, it is suggested that smaller queens are probably less viable than larger queens as observed in previously studied epiponines.

Non-allometric caste differences in Agelaia vicina (Hymenoptera, Vespidae, Epiponini)

Non-allometric and clear-cut caste dimorphism were found in two colonies of the social wasp Agelaia vicina. Such type of allometry was previously recorded in the Epiponini and its origin is pre-imaginally determined as in the other analysed species which present caste dimorphism. Multivariate analyses evidenced that the most intercastes discriminant characters were found in the metasoma and mesosoma while head differences were slight. Although queens were characterized by marked ovary development and insemination, the presence of some uninseminated queens was detected in one of the analysed colonies.
