13. Estudo teórico-experimental do efeito da flexão da ferramenta no processo de microfresamento / Theorical and experimental study on tool deflection effect in micromilling process
The tool deflection, in end milling operations, is responsible to intervene negatively on the workpiece surface quality and can also cause a premature tool failure (breakage).The present work aims at studying experimentally the effects of tool deflection when end milling with 0,8 mm diameter in microoperations. The experimental tests had intended to identify

14. O socioambientalismo na perspectiva da sociedade civil latino americana : uma analise no ambito das conferencias das Nações Unidas / Social environmentalism in the Latin American civil society perspective : an analysis in the United Nations conferences
In this thesis objective was to investigate the construction of the social environmental approach in the perspective of the Latin America civil society at international level, with the cutting out in the international conferences and meetings organized by the United Nations on environment. In this sense, the intent was to understand the origins, the meanings

15. Relaxação langrangena com divisão em clusters para alguns problemas de otimização modelados em grafos de conflitos / Lagrangean relaxation with clusters for some optimization problems modeled by conflict graphs
Muitos problemas de otimizaçãoo combinatória podem ser modelados por meio de um grafo especial denominado grafo de conflitos. Quando estes grafos apresentam-se esparsos, bem adaptados para uma fase de particionamento, ou seja, quando apresentam agrupamentos de vértices bem definidos (clusters), as arestas que conectam os clusters podem ser relaxadas no s

16. Relaxação langrangena com divisão em clusters para alguns problemas de otimização modelados em grafos de conflitos / Lagrangean relaxation with clusters for some optimization problems modeled by conflict graphs
Several combinatorial optimization problems can be modeled by a special graph denoted conflict graph. When these graphs are sparses well-adapted for a previous clustering phase, i.e, when they have clusters of vertices, the edges inter clusters can be relaxed in a lagrangean fashion, and the relaxed problem can be decomposed into sub problems and solved. Thi

17. Modelos de gestão da terceirização de tecnologia da informação: um estudo exploratório / Models of information technology outsourcing management: an exploratory study
Outsourcing, or the process of transferring activities to third parties has being underused for a long time and it is becoming a common practice. This is also true in the Information Technology area, ever since computers have been introduced in organizations. There are many reasons associated to the partial or total outsourcing of activities and services in

18. Conceito de área: uma proposta de ensino-aprendizagem
The objective of the research is to study phenomena that influence the teaching and learning of the concept of area in Ensino Fundamental (students aged 7-15). It presents a teaching proposal for the concept of area and a reflection about the learning of this concept through a teaching sequence involving the decomposition and composition of plane figures. Th

19. A representação do mestre na educação a distância : um estudo de caso baiano
This work is to obtain information enabling the representation of the outline figure of the master in the Distance Education and lift parameters for comparison with the representation of teachers in the same environment. It is a case study on a group of Master of Bahia, in formation through the EaD. This is a study that explores the format of the representat

20. Estudo de monocromadores assimetricos de raios-X
Asymmetric X-ray monochromators, firsts introduced by I. Fankuchen ( 1937 ) with the purpose of concentrating an X-ray beam have been the subject of numerous investigations. Evans, Hirsch and Kellar as early as 1948, based ther well known and hitherto unchallenged study on the hypothetic existence of a non-ref1ecting surface layer with an absorption coeffici

21. Responses to facial and non-facial stimuli presented tachistoscopically in either or both visual fields by patients with the Capgras delusion and paranoid schizophrenics.
An experiment was carried out designed primarily to test A B Joseph's suggestion that patients with Capgras delusion may have problems integrating information between the two cortical hemispheres; and at the same time it was meant to examine J Cutting's ideas linking schizophrenia in general, and the Capgras delusion in particular, to right hemisphere dysfun

22. The Phenomenon of „Vesting” in Ring Chromosomes and Its Role in the Mutation Theory and Understanding of the Mechanism of Crossing-Over
After X-ray irradiation of Crepis capillaris dry seeds the authors detected, in addition to usual patterns of chromosome mutations, a new phenomenon of normal rod-shaped chromosomes being „vested,” or encircled, by ring chromosomes. An analysis of the phenomena has demonstrated that the ring-chromosome production is connected with an X-ray-induced format
