1. Mechanical and histological evaluation of a titanium device for orthodontic anchorage, placed with or without cyanoacrylate adhesive
RESUMO Objetivos: este estudo teve como objetivo realizar uma avaliação histológica de um mini-implante para ancoragem em Ortodontia. Avaliou-se, também, a carga de cisalhamento e o padrão de fratura imediatamente e após 30 e 60 dias da sua inserção, com ou sem o uso do adesivo N-butil-2-cianoacrilato. Métodos: noventa e seis mini-implantes (Arro

2. QUÉ PUEDE DECIRNOS LA RELATIVIDAD GENERAL RESPECTO DE LA FLECHA DEL TIEMPO
Abstract Traditionally, from the viewpoint of the philosophy of physics, the problem of the arrow of time has been addressed considering the formal properties exhibited by the fundamental physical laws. In particular, if the laws remain invariant under time reversal, then a privileged temporal direction cannot be distinguished on physical grounds. On the con

3. Producción artesanal indígena: saberes y prácticas de los Qom en la ciudad de Rosario
The present work concentrates in knowledge and practicing referred to handcraft production of Qom people. We approach different productive headings as: basketry, pottery, netting, arch and arrow production and necklace manufacture, individual or domestic ways of production and different sorts of organization as: cooperative activity, associations and indepen

5. Comportamento assintótico para soluções de certas equações diferenciais funcionais periódicas / Asymptotic behavior of solutions to certain periodic functional differential equations
We are interested in the study of the asymptotic behavior of the solutions of a class of linear autonomous Functional Differential Equations (FDE) of neutral type, where the coeficients of the non neutral part are periodic functions with common period w and the time delays are multiples of w. We employ the spectral theory for linear operators applied to the

6. Telicidade e detelicização : semantica e pragmatica do dominio tempo-aspectual
This dissertation investigates the phenomenon of detelicization, represented by sentences such as "João leu o livro por 1 semana" ("John read a book for 1 week"), in which there is a telic event (i.e., an event which has a non-arbítrary final point) followed by an adjunct like "for X time", which, according to the literature, is incompatible with telic eve

7. Quantum cosmology and the arrow of time
Although most fundamental laws are invariant under time reversal, experience exhibits the presence of irreversible phenomena - the arrows of time. Their origin lies in cosmology, and I argue that only quantum cosmology can provide the appropriate formal framework. After briefly reviewing the formalism, I discuss how a simple and natural boundary condition ca

8. Planejando para a incerteza: a gestão do complexo nas organizações
Time and complexity are in the roots of the contemporary thinking and new thoughts on new sciences. ln natural sciences inserting the concept of time as the fundamental element to the understanding of complex phenomena, dissipative structures and uncertainty at the material leveI raised a new pattern to the knowledge about life evolution and to inserting the

9. Lamella design (high rate) and conventional flotation units applied to the post-treatment of the effluent from a system made up anaerobic reactor followed by aerobic reactor treating domestic sewage / Emprego da flotação lamelar de alta taxa e convencional como pós-tratamento do efluente de sistema constituído de reator anaeróbio seguido de reator aeróbio tratando esgoto sanitário
The aim of this research was the study of the lamella design (high rate) and conventional dissolved air flotation (DAF) process potentiality of application as the final part of a domestic sewage sequential treatment system made up anaerobic reactors (UASB) followed by aeration tank. The work, developed at the Jardim das Flores WWTP of Rio Claro city, was sep

10. "Diálogos sobre o tempo - arte e ciência, educação" / "Diálogos sobre o tempo - arte e ciência, educação"
This work aims to discuss some aspects of the notion of Time presented to high school students in the subject of Physics. Presuming that the notion of time, and its possible meanings, is well known - and thus restrictive, since the theme is complex enough to have demanded contribution from most areas of human knowledge for its understanding -, we propose to

11. Composition and Distribution of Adenylates in Soybean (Glycine max L.) Nodule Tissue.
Adenylates (ATP, ADP, and AMP) may play a central role in the regulation of the O2-limited C and N metabolism of soybean nodules. To be able to interpret measurements of adenylate levels in whole nodules and to appreciate the significance of observed changes in adenylates associated with changes in O2-limited metabolism, methods were developed for measuring
