13. Resistance to pyrethroids and organophosphorus acaricides in cattle tick Boophilus microplus (Acari Ixodidae) / Resistencia do carrapato Boophilus microplus (Acari: Ixodidae) aos piretroides e organofosforados e o tratamento carrapaticida em pequenas fazendas
The cattle tick - Boophilus microplus (Acari: Ixodidae) ? is one of the principal causes of economic losses in the cattle farms in São Paulo state. The current situation of the tick control is characterized by a crisis in the production of new molecules with acaricidal properties and by an increasing in the parasites resistance to the products used to contr

14. PolÃticas de avaliaÃÃo docente no ensino superior: o significado da GratificaÃÃo de EstÃmulo à DocÃncia (GED) na Universidade Federal de UberlÃndia
The present research has its axle- tree in the field of evaluation of politics for the superior education, established since the nineties from the XX century. More specifically, it pursuits to learn the meaning of the implement of Teaching Incentive Gratification (TIG) at the Federal University of UberlÃndia (UFU). For so, it has been analyzed the new confi

16. A STRATEGY MRAC WITHOUT SENSOR OF SPEED FOR TUNNING OF THE CONTROL WITH ORIENTATION FOR THE FIELD OF INDUCTION ENGINES / UMA ESTRATÉGIA MRAC SEM SENSOR DE VELOCIDADE PARA SINTONIA DO CONTROLE COM ORIENTAÇÃO PELO CAMPO DE MOTORES DE INDUÇÃO
Na maioria das aplicações industriais de acionamentos com alto desempenho ca são utilizadas. No entanto, este tipo de acionamento depende fortemente de um controle de corrente eficiente e do tipo de estratégia de controle utilizada. Portanto, neste trabalho é realizado um estudo dos principais controladores PI de correntes usados em correntes ca e é pr

17. Formação profissional, motivos e crenças relativas a velhice e ao desenvolvimento pessoal entre professores de Universidades da Terceira Idade
Systematic enrollment in education of experts designed to the attendance of the instructional, administrative and research requirements associated to the improving participation of older adults, is an important challenge to be faced by those universities that maintains educational programs addressed to older people. This kind of action is an indicator of the

18. Implementação digital utilizando DSP do controle por orientação do fluxo do rotor : metodos direto e indireto
In this work the digital implementation of a field rotor flux oriented based control of a squirrel cage induction motor, using a versatile Motorola 56001 digital signal processor is presented. Two methods of orientation are studied: the direct and indirect. The control system contains a PI speed controller. An introductory investigation of the use of Genetic

20. Mecanismos de alojamento de magmas granitóides :exemplo do plúton de Japi(RN)
This dissertation describes the igneous suites of the Japi granitoid pluton, intrusive in the Paleoproterozoic gneiss-migmatite complex of the eastern domain of the Seridó Belt, northeastern Brazil. Field relations show that the pluton is affected by strong deformation associated to the Brasiliano orogeny (known as the D3 phase) , with a NW-trending extensi

21. Acionamento de um motor de indução com comandos suaves de torque, utilizando a tecnica de controle vetorial por campo orientado
The project and implementation of control systems whith high performance and reliability for three phase induction motors need a complete modeling of the machine, in a moving reference system and the utilization of the vectorial method. The purpose of this work is the implementation of a system which uses the rotor field orientation technique (indirect metho

22. Electrical cues regulate the orientation and frequency of cell division and the rate of wound healing in vivo
Controlling cell division is fundamental. One environmental cue that exerts profound control over both the orientation and frequency of cell division in vivo is a naturally occurring, wound-induced electric field (EF). Wounds in rat corneas generate endogenous EFs in the plane of the epithelial sheet because the transcorneal potential difference (TCPD; +40 m

23. Alteration of Oriented Deposition of Cellulose Microfibrils by Mutation of a Katanin-Like Microtubule-Severing Protein
It has long been hypothesized that cortical microtubules (MTs) control the orientation of cellulose microfibril deposition, but no mutants with alterations of MT orientation have been shown to affect this process. We have shown previously that in Arabidopsis, the fra2 mutation causes aberrant cortical MT orientation and reduced cell elongation, and the gene

24. Effects of exposure to lines of one or two orientations on different cell types in striate cortex of cat.
We raised cats using goggles to control early visual exposure (stripe-rearing). Four conditions were used: (a), both eyes exposed to 0 degrees lines, (b), both eyes exposed to 90 degree lines, (c), one eye exposed to 45 degree lines, the other to 135 degree lines, (d), one eye exposed to 0 degree lines, the other to 90 degree lines. At the completion of the
