1. Physiological responses and animal behavior in Bonsmara-Hereford crosses vs. Hereford purebred on environment stress
ABSTRACT: Adaptative traits (rectal temperature-RT, respiratory rate-RR) and grazing behavior (Grazing, Ruminating and Rest time, and Sun or Shade time) of Bonsmara-Hereford crossbred-BH, n = 15, and purebred Hereford-HH, n = 18, yearling heifers, in a grazing system of Uruguay. Environment characterization was made using THIadjusted by radiation and wind sp

2. Association of hypotalamic POMC, NPY and IRS2 with feeding behavior in norma and overweight Wistar rats / Associação do PMOC, NPY e IRS2 hipotalâmicos com padrões de comportamento alimentar em ratos wistar normais e sobrepeso
The feeding behavior of a specie is determined by a group of phylogenetic, ontogenetic, and epigenetic features, and regulated by internal and external factors to the organism. The natural phenomena that govern life in our planet are mainly periodic, and the food stocks is not an exception. Each harvest is followed by a time between harvests, and this rhythm

3. Redes interorganizacionais horizontais como sistemas adaptativos complexos: um estudo em uma rede de supermercados do Sul de Minas Gerais. / Horizontal inter-organizational networks as a complex adaptative system: a study in a network of supermarkets in the south of Minas Gerais
The horizontal inter-organizational networks (HINs) have been studied under distinct scopes. Aiming to contributing to studies about them, this piece of work takes a different look at them as a starting point into understanding the uprising and development phenomenon of such organizational form. The precepts of Complex Adaptive Systems (CAS) along with those

4. Sonhos antecipatórios: influência de um evento significativo da vigília na atividade onírica
In most cultures, dreams are believed to predict the future on occasion. Several neurophysiological studies indicate that the function of sleep and dreams is to consolidate and transform memories, in a cyclical process of creation, selection and generalization of conjectures about the reality. The aim of the research presented here was to investigate the pos

5. Resistência fisiológica e comportamental de populações de Sitophilus zeamais à permetrina, esfenvalerato e esfenvalerato + fenitrotiona / Physiological and behavioral resistance of populations of Sitophilus zeamais to permethrin, esfenvalerate and esfenvalerate + fenitrothion
The maize weevil, Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae) is considered the main pest of stored maize in Brazil and its control is achieved mainly by insecticides. The massive and intensive use of these compounds may lead to selection of resistant populations and consequently compromise the control efficacy of this insect pest in Bra

6. Caracterização termomecânica de compósitos híbridos com memória de forma
The Shape Memory Alloys - SMA - are materials with the ability to recover a certain geometric form previously established upon heating. This singular behavior enables their application in many situations, from orthodontic arches and medical instruments to adaptative structures for shape and vibration control. Due to the complexity of their thermomechanical b

7. Secreção e sensibilidade periférica à insulina e hormônios contra-regulatórios do morcego hematófago Desmodus rotundus
In general, mammals fed on high protein diets (HP) are more resistant to starvation. However, the hematophagous bat Desmodus rotundus, althougth having a HP diet (blood), is markedly susceptive to the food deprivation, presenting severe hypoglycemia after 24h of starvation. Besides, this species has small stores of hepatic glycogen and adipose tissue lipid,

8. Análise de possíveis efeitos desejáveis do controle aversivo na aprendizagem de comportamento eficaz
In this study, the hypothesis that contingences of punishment and negative reinforcement which constitute the area called ?aversive control?, take part in the process of establishment and maintenance of important behaviors, which can increase the probability of an individual to deal better with the adversities of his environment; as well as to contribute wit

9. Análise comparativa do alcance manual em lactentes jovens pré-termo e a termo.
This longitudinal study investigated the development of reaching behavior in the seated position in preterm infants at the ages of 5, 6 and 7 months by analyzing kinematic variables (straightness and adjustment indexes, movement unit, mean and final velocities). The correlation between kinematic variables and grasping was verified. The participants were nine

10. Uma contribuiÃÃo ao estudo da sedimentaÃÃo gravitacional em batelada
Thickeners are equipments that uses the gravitational force as separating agent of suspended solid particle in liquid chains of industrial processes. The frequent use of the settlers in chemical industries is the reason of the interest on the development of studies on the subject. The batch sedimentation is the starting point for the project of continuous in

11. Elderly in hemodyalisis: adaptative process in face of the treatment repercussion / Idosos em hemodiÃlise: processos adaptativos em face das repercussÃes do tratamento
The increase in the occurrence of chronic kidney disease patients and the consequent need of substitutive renal therapies, mainly in the group of elderly, requires the intervention of health professionals, either in the assisting field or in scientific investigation, as a way to contribute for life maintenance. The present study objectified to evaluate the a

12. Resistência de populações do caruncho do milho a inseticidas fosforados / Organophosphate resistance in maize weevil populations
Sitophilus zeamais Motsch. (Coleoptera: Curculionidade) é reconhecidamente importante pelos danos causados a grãos de milho armazenados. Essa espécie tem sido bastante estudada por responder à pressão de seleção para resistência a inseticidas, dificultando seu controle. Neste trabalho foi realizado um levantamento da resistência fisiológica e compo
