1. Base-temperature, plastochron and chia (Salvia hispanica L. - Lamiaceae) yield for different sowing times
ABSTRACT Chia is a plant whose seeds are used in cooking and is a natural source of omega-3 fatty acids, fiber and protein, as well as other important nutritional components such as antioxidants. The objective of this work was to estimate the base temperature, plastochron and chia seed yield for different sowing times in Cruz Alta, Rio Grande do Sul, Brazil.

2. EFFECTS OF SOIL WATER AVAILABILITY AND ORGANIC MATTER CONTENT ON FRUIT YIELD AND SEED OIL CONTENT OF CASTOR BEAN1
ABSTRACT The objective of this study was to assess the sensitivity of the castor bean cultivar “BRS 188 Paraguaçu” to available soil water for plants and soil organic matter content based on their effects on fruit yield and seed oil content. A 2 × 4 factorial experiment was conducted from October 2008 to March 2009 under field conditions using randomiz

3. Sustained reduction of healthcare-associated infections after the introduction of a bundle for prevention of ventilator-associated pneumonia in medical-surgical intensive care units
Abstract Background Infection control interventions can be erroneously interpreted if outcomes are assessed in short periods. Also, statistical methods usually applied to compare outcomes before and after interventions are not appropriate for analyzing time series. Aims To analyze the impact of a bundle directed at reducing the incidence of ventilator-asso

4. SORPTION ISOTHERMS AND ISOSTERIC HEAT OF PERICARP AND ENDOSPERM TISSUES OF ARABICA COFFEE FRUIT
ABSTRACT The aim of this study was to evaluate and model the hygroscopic equilibrium and isosteric heat curves of pericarp and endosperm tissues of arabica (Coffea arabica) coffee fruit, in different temperature and relative humidity conditions. Sorption isotherms were drawn under temperatures from 20°C to 70°C and relative humidity ranging between 10% and

5. Incorporação de biomassa de fabáceas ao substrato de plantio para controle da podridão-de-escleródio (Sclerotium rolfsii) em cubiu (Solanum sessiliflorum)
RESUMO O cultivo do cubiu (Solanum sessiliflorum Dunal), no Amazonas, é limitado pela alta incidência da doença podridão-de-escleródio (Sclerotium rolfsii Sacc.) e a incorporação de material vegetal ao substrato de cultivo altera a microflora presente. O trabalho objetivou avaliar o potencial de controle da podridão-de-escleródio em cubiu por meio d

6. Requirement of Digestible Methionine + Cystine to Molted Laying Hens
ABSTRACT The present study aimed to determine the ideal requirement of digestible methionine + cystine to molted laying hens. The experimental period lasted 105 days, divided into five periods of 21 days. 144 Hisex White laying hens with 84 weeks-of-age were used. The experimental design was completely randomized with treatments constituted for six levels of

7. Fish Waste Oil in Laying Hens* Diets
ABSTRACT The present study aimed to evaluate increasing levels of fish waste oil in laying hens diets on performance, egg quality, and sensory features of the eggs. 192 Hisex White laying hens with 29 weeks of age were used, with water and food ad libitum. The experimental design was completely randomized consisting of eight treatments corresponding to the i

8. Effect of In Ovo Feeding of L-Glutamine to Chick Embryos
ABSTRACT In ovo feeding (IOF), injecting nutrients into the amnion of the avian embryo may enhance hatchability, gastrointestinal development and serum metabolism changes. This hypothesis was evaluated with 5 IOF solutions containing L-glutamine. Were used 315 fertile Rhode Island Red eggs were used (breeders with 32-weeks). The experimental design was compl

9. K-NEAREST NEIGHBORS METHOD FOR PREDICTION OF FUEL CONSUMPTION IN TRACTOR-CHISEL PLOW SYSTEMS
ABSTRACT Most important farm operations require a significant amount of energy, and this consumes a major portion of the farm's budget. Consequently, analyzing the fuel consumption of agricultural machinery for farm operations of different sizes makes it possible to predict fuel consumption to set an appropriate budget for energy. The main purpose of this st

10. Carreiras Políticas na Câmara dos Deputados: Uma Análise Quase-Experimental
RESUMO Este artigo investiga o efeito das eleições sobre as carreiras dos candidatos a deputado federal no Brasil. Com um desenho de regressão descontínua, ele mostra que os resultados de uma única eleição têm impactos substantivos na carreira parlamentar: obter um mandato na Câmara causa um aumento de cerca de 25 pontos percentuais a mais na chance

11. Wood ash and water availability in the production of Paiaguás-grass
Resumo Objetivou-se avaliar a produção do capim-paiaguás (Urochloa brizantha) em função de doses de cinza vegetal e disponibilidades hídricas do Latossolo Vermelho do Cerrado. O experimento foi realizado em casa de vegetação com delineamento em blocos casualizados em esquema fatorial 5x5 fracionado, correspondendo a cinco doses de cinza vegetal (0; 8

12. Estimativa da resistência característica à tração da madeira na direção paralela às fibras por meio de modelos probabilísticos
RESUMO Para um dimensionamento de estruturas de madeiras dentro das exigências de segurança, a resistência para determinada solicitação mecânica é calculada com base em seu valor característico, correspondente ao percentil de 5% de um determinado modelo de distribuição de probabilidades. A norma brasileira NBR 7190 [1] estabelece, para pequenas amo
