37. Estratégias de suplementação para vacas e para novilhas de corte dos quatro aos dezoito meses de idade / Supplementation strategies for cows and beef heifers from four to eighteen months old
Foram realizados três experimentos com o objetivo de avaliar Estratégias de suplementação para vacas e para novilhas de corte dos quatro aos dezoito meses de idade. No primeiro experimento objetivou-se avaliar o desempenho produtivo, o consumo de pasto, bem como consumo e digestibilidade dos nutrientes ingeridos por novilhas Nelore ou mestiça, com predo

38. Efeito das estratégias de Planejamento da Ação e Enfrentamento de Obstáculos sobre a redução do consumo de sal entre mulheres hipertensas : um estudo piloto / Effect of the strategies of action and coping planning on salt consumption among hypertensive women : a pilot study
Estudos evidenciam elevado consumo de sódio entre pacientes hipertensos. Nesta população, a motivação/intenção, principal determinante da redução da adição de sal no preparo dos alimentos, explicou 22% da variabilidade deste comportamento, apontando para um gap na relação intenção-comportamento formado principalmente por sujeitos que possuem i

39. Ecologia trófica da ictiofauna e simpatria de espécies congenéricas no córrego da Lapa, bacia do Alto Paraná, estado de São Paulo, Brasil
Streams and rivers are loctic environments characterized for a strong and unidirectional water flow. These environments in general have the light incidence partial or totally obstructed by the canopy of the riparian vegetation showing a high dependence of allocthonus organic inputs. The stream fishes are usually small sized, with reproductive strategies adap

40. Ecologia trÃfica de Rhinella hoogmoedi Caramaschi e Pombal, 2006 (Anura, Bufonidae) em uma floresta Ãmida do estado do CearÃ, Brasil / Trophic ecology of Rhinella hoogmoedi Caramaschi e Pombal, 2006 (Anura, Bufonidae) in a humid forest in the State of CearÃ, Brazil.
The understanding of trophic relations among species is essential for the comprehension of their ecological evolutionary history, as well as in the understanding of how communities are structured. The consumption of the same food resource by two or more species may result in the evolution of mechanisms capable of reducing this inter- specific competition, wi

41. Growth curve of Nellore calves reared on natural pasture in the Pantanal
Weight-age and hip height-age relations of Nellore calves, from birth to 10 months old were fitted using a logistic model including sex and year of birth as fixed effects. Calves and their dams were reared on natural pasture using continuous grazing system. The crude protein content and total digestible nutrients were analyzed for pasture selected by the ani

42. Spatial and temporal structure of fish assemblages in a hyperhaline coastal system: Ría Lagartos, Mexico
The spatial and temporal fish species assemblages were analyzed throughout two annual cycles (2004-2005 and 2007-2008) in the Ría Lagartos Lagoon system, Mexico, via non-parametric multivariate analyses. We compared density and biomass of fish species among five habitat types defined by combinations of structure and environmental characteristics (hyperhalin

43. A new look into the small-scale dispersal of free-living marine nematodes
We tested experimentally the hypothesis that prevailing locomotion/feeding strategies and body morphology may lead to more active dispersal of free-living marine nematodes, besides passive transport. Neutral Red was applied to the sediment inside cores and the red plume formed during the flood tide was divided into near, middle, and distant zones. At 0.5 m a

44. Control strategies applied for reducing the vibration and torque ripple of a special Switched Reluctance Motor
Despite its robustness the Switched Reluctance Motors (SRMs) present some inconvenient drawbacks as a major torque ripple, vibration and acoustic noise when compared to other types of motors. These characteristics are usually related to factors such as the salient poles in the stator and in the rotor, the switched feeding and the control strategy imposed by

45. Ecological patterns of blood-feeding by kissing-bugs (Hemiptera: Reduviidae: Triatominae)
Host use by vectors is important in understanding the transmission of zoonotic diseases, which can affect humans, wildlife and domestic animals. Here, a synthesis of host exploitation patterns by kissing-bugs, vectors of Chagas disease, is presented. For this synthesis, an extensive literature review restricted to feeding sources analysed by precipitin tests

46. The opportunistic feeding and reproduction strategies of the annual fish Cynopoecilus melanotaenia (Cyprinodontiformes: Rivulidae) inhabiting ephemeral habitats on southern Brazil
A maioria dos peixes da família Rivulidae são popularmente conhecidos como anuais por completarem todo seu ciclo biológico em pequenos corpos de água temporários que secam obrigatoriamente em determinados períodos do ano causando a morte dos indivíduos adultos. Possuem características biológicas peculiares como pequeno porte, maturação sexual prec

47. Flight, feeding and reproductive behavior of Phyllophaga cuyabana (Moser) (Coleoptera: Melolonthidae) adults.
Phyllophaga cuyabana is a univoltine species and its development occurs completely underground. Its control by conventional methods, such as chemical and biological insecticides, is difficult, so it is important to understand its dispersion, reproduction, and population behavior in order to determine best pest management strategies. The objective of this wor

48. Uma análise comparada das políticas de alimentação escolar na Bolívia, no Brasil e no Chile
Latin American school feeding programs are public social policies with multiple goals and benefits. These actions have taken on a varied scope as they address concerns related to health, education, social welfare and economic development. As education policies they have become visible instruments that guarantee equality and opportunities for students. They a
