1. Development of a weather-based forecasting model for Alternaria leaf blight of carrot
RESUMO No presente trabalho foram estudadas, em condições de câmara climatizada, a influência da temperatura (10, 15, 20, 25 e 30°C) e da duração do molhamento foliar (6, 12, 24 e 48 horas) na severidade da queima das folhas da cenoura incitada por Alternaria dauci. A densidade relativa de lesões foi influenciada pela temperatura e pela duração do

2. Progresso da queima das pontas das folhas da cebola sob diferentes programas de aplicação de fungicidas
RESUMO A queima das pontas das folhas da cebola, causada por Botrytis squamosa, é controlada por meio de pulverizações foliares com fungicidas seguindo um calendário fixo, sem considerar o progresso da doença. O regime de pulverização baseado em um sistema de previsão pode prever seu progresso e com isso possibilitar a redução do número de pulveri

3. Relações lineares entre incidência e severidade foliar da queima das pontas das folhas da cebola
RESUMO A ocorrência da queima das pontas das folhas da cebola pode reduzir o rendimento e comprometer a qualidade do bulbo. O objetivo do trabalho foi avaliar a relação entre incidência e severidade na intensidade da queima das pontas das folhas da cebola. O experimento foi conduzido com o cultivar Empasc 352 – Bola Precoce no Instituto Federal Catarin

4. A glimpse of the future in animal nutrition science. 2. Current and future solutions
ABSTRACT Despite tremendous advancements in the livestock sector, additional opportunities exist to improve even further livestock production around the globe. Forecasting is not an exact science and it relies heavily on past and current knowledge. Improvements in the nutritional sciences (both human and animal) include a better understanding of agents that

5. SEVERIDADE DE OCORRÊNCIA DE MANCHA DE SEPTÓRIA E PRODUTIVIDADE DO GIRASSOL IRRIGADO / SEVERITY OF OCCURRENCE OF SEPTORIA LEAF SPOT AND YIELD OF IRRIGATED SUNFLOWER
This study aimed to evaluate the severity of occurrence of septoria leaf spot in sunflower, its association with meteorological variables and its effect on yield of field irrigated sunflower. The experiments were conducted in Santa Maria - RS during the 2008 spring season and during the 2009 fall growing season, with sowings in September and in February, res

6. SISTEMAS DE PREVISÃO DE OCORRÊNCIA DE REQUEIMA EM CLONES DE BATATA SUSCETÍVEIS E RESISTENTES / FORECASTING SYSTEMS OF LATE BLIGHT OCCURRENCE IN SUSCEPTIBLE AND RESISTANT POTATO CLONES
A ocorrência da requeima (Phytophthora infestans (Mont.) de Bary) nas lavouras de batata é responsável pela grande quantidade de fungicidas utilizados em cada época de cultivo. A utilização de sistemas de previsão e de cultivares resistentes à requeima são importantes ferramentas para reduzir a quantidade de fungicidas utilizados e com isso diminuir

7. Process of knowledge discovery in databases for analysis and warning of crop diseases and its application on coffee rust / Processo de descoberta de conhecimento em bases de dados para a analise e o alerta de doenças de culturas agricolas e sua aplicação na ferrugem do cafeeiro
Sistemas de alerta de doenças de plantas permitem racionalizar o uso de agrotóxicos, mas são pouco utilizados na prática. Complexidade dos modelos, dificuldade de obtenção dos dados necessários e custos para o agricultor estão entre as razões que inibem o seu uso. Entretanto, o desenvolvimento tecnológico recente - estações meteoro lógicas autom

8. Forecasting the Need for Dialysis Services in Ontario, Canada to 2011
Careful projections of the demand for dialysis services are important to assist healthcare planners in forecasting the need for equipment, facilities and personnel. We used time series techniques to model the historical incidence and prevalence counts and to forecast the predicted number of patients requiring dialysis in the province of Ontario to 2011. We s

9. Forecasting cephalosporin and monobactam antibiotic half-lives in humans from data collected in laboratory animals.
The postdistribution half-lives of 10 cephalosporin and 2 monobactam antibiotics in humans were predicted from data obtained in other mammals. This forecasting was accomplished with the allometric equation t1/2 = aWb, where a is the y intercept and b is the slope obtained from the log-log plot of antibiotic half-life (t1/2) versus body weight (W). Dimensionl

10. Creative use of existing clinical and health outcomes data to assess NHS performance in England: Part 2—more challenging aspects of monitoring
In the second of their two articles about using existing routine data to assess performance in the NHS, the authors make practical suggestions about using data for mental health care, potentially avoidable deaths, and forecasting coronary heart disease outcomes, and raise issues about assumptions and technical aspects for discussion

11. Fractal dynamics in physiology: Alterations with disease and aging
According to classical concepts of physiologic control, healthy systems are self-regulated to reduce variability and maintain physiologic constancy. Contrary to the predictions of homeostasis, however, the output of a wide variety of systems, such as the normal human heartbeat, fluctuates in a complex manner, even under resting conditions. Scaling techniques

12. Radiological findings as predictors of mortality in Quebec asbestos workers.
Two cohorts of chrysotile miners and millers in Quebec were selected to study the extent to which chest radiographs taken while still employed predict mortality. The paper presents mainly findings in much the larger cohort, which consisted of 4559 men (two-thirds past workers) whose latest radiograph had been assessed by one of six experienced readers into w
