Crescimento de mudas de dendezeiro produzidas em tubetes plásticos durante o previveiro em função da aplicação de doses crescentes de Osmocote®.

Atualmente, a utilização de tubetes plásticos durante a fase de previveiro na formação de mudas de dendezeiro (Elaeis guineensis Jacq.) tem sido estudada, apresentando-se como boa alternativa ao sistema de produção tradicional de mudas, mas esta metodologia ainda carece de aperfeiçoamento. Este trabalho teve como objetivos verificar o efeito da adição de doses crescentes de Osmocote®, durante a fase de previveiro, no crescimento e na partição de matéria seca de mudas de dendezeiro produzidas em tubetes plásticos

Bias in protein and potassium intake collected with 24-h recalls (EPIC-Soft) is rather comparable across European populations

Purpose: We investigated whether group-level bias of a 24-h recall estimate of protein and potassium intake, as compared to biomarkers, varied across European centers and whether this was influenced by characteristics of individuals or centers. Methods: The combined data from EFCOVAL and EPIC studies included 14 centers from 9 countries (n = 1,841). Dietary data were collected using a computerized 24-h recall (EPIC-Soft). Nitrogen and potassium in 24-h urine collections were used as reference method. Multilevel linear regression analysis was performed, including individual-level (e.g., BMI) and center-level (e.g., food pattern index) variables. Results: For protein intake, no between-center variation in bias was observed in men while it was 5.7% in women. For potassium intake, the between-center variation in bias was 8.9% in men and null in women. BMI was an important factor influencing the biases across centers (p <0.01 in all analyses). In addition, mode of administration (p = 0.06 in women) and day of the week (p = 0.03 in men and p = 0.06 in women) may have influenced the bias in protein intake across centers. After inclusion of these individual variables, between-center variation in bias in protein intake disappeared for women, whereas for potassium, it increased slightly in men (to 9.5%). Center-level variables did not influence the results. Conclusion: The results suggest that group-level bias in protein and potassium (for women) collected with 24-h recalls does not vary across centers and to a certain extent varies for potassium in men. BMI and study design aspects, rather than center-level characteristics, affected the biases across center

A study of emotions in requirements engineering.

Proceedings of: 3rd World Summit on the Knowledge Society (WKKS 2010), September 22-24, 2010, Corfu (Greece)Requirements engineering (RE) is a crucial activity in software development projects. This phase in the software development cycle is knowledge intensive, and thus, human capital intensive. From the human point of view, emotions play an important role in behavior and can even act as behavioral motivators. Thus, if we consider that RE represents a set of knowledge-intensive tasks, which include acceptance and negotiation activities, then the emotional factor represents a key element in these issues. However, the emotional factor in RE has not received the attention it deserves. This paper aims to integrate the stakeholder’s emotions into the requirement process, proposing to catalogue them like any other factor in the process such as clarity or stability. Results show that high arousal and low pleasure levels are predictors of high versioning requirements.Publicad

Produção de mandioca em cultivos consorciados com plantas leguminosas no Estado do Amazonas.

Na Amazônia, o sistema de uso da terra normalmente tem elevado custo ambiental e baixo nível de competitividade. Práticas alternativas de manejo que minimizem o impacto da agricultura itinerante são alternativas a este modelo. Este trabalho teve como objetivo avaliar o crescimento vegetativo e a produtividade de duas variedades de mandioca em diferentes sistemas de cultivo associados com leguminosas e plantas espontâneas, com e sem calagem e adubação
