13. Dez idosas em análise A mulher e sua sexualidade na vida real e na ficção
The present work is a quarrel of psychoanalytics subjects of the sexuality of elderly women. For they had been in such a way analyzed, under the light of the psychoanalysis Lacaniana, 10 cases (life histories) of elderly women with focus in referring questions to the sexuality/affectivity of them. Moreover, they had been described popularly known histories,

14. Dois Elétrons em cadeias cristalinas e aperiódicas: efeito de campo elétricos.
Recently much attention was drived to the interplay between dynamical localization and electron-electron interaction. In this master degree thesis we contribute to futher understanding of the phenomenon of electronic Bloch oscillations in both periodic and apperiodic low-dimensional systems with two interacting electrons. We followed two distinct quantum for

15. Caracterização funcional de componentes da resposta ao dano DNA em Aspergillus nidulans: os genes chkA, chkB e ddbA / Functional Characterization of DNA damage response components in Aspergillus nidulans: the ddbA, chkA and chkB genes.
The constant exposure of different organisms to agents that damage the DNA structure, has provided the cells with repair mechanisms that are conserved during evolution. In mammal cells, the DNA damage repair pathways and the cell cycle checkpoint regulation act together to prevent cell cycle progression before the repair is performed avoiding mutation fixaxi

16. A subplacenta da paca (Agouti paca, Linnaeus 1766) / The subplacenta of the paca (Agouti paca, Linnaeus 1766)
The rodents of suborder hystricomorph, in which is classified the Agouti paca, present hemochorial type placentation and develops an unique structure known as subplacenta. In spite of many report of its presence in several species, the possible functions of this structure related to placenta and pregnancy remains speculative, mainly due to the diversity of f

17. Colocalization of coilin and nucleolar proteins in Cajal body-like structures of micronucleated PtK2 cells
Cajal bodies (CB) are ubiquitous nuclear structures involved in the biogenesis of small nuclear ribonucleoproteins and show narrow association with the nucleolus. To identify possible relationships between CB and the nucleolus, the localization of coilin, a marker of CB, and of a set of nucleolar proteins was investigated in cultured PtK2 cells undergoing mi

18. MEMÓRIA DE TRADUÇÃO: AUXÍLIO OU EMPECILHO? / TRANSLATION MEMORY: AID OR HANDICAP?
Considering the increasingly important role played by computer-aided translation tools in the work of professional translators, the discussion about their use gains special interest. This study focuses on only one of these tools: translation memory systems, which were developed to ensure productivity gains, more consistency and cost savings. The objective is

19. Iron homeostasis related genes in rice
Iron is essential for plants. However, excess iron is toxic, leading to oxidative stress and decreased productivity. Therefore, plants must use finely tuned mechanisms to keep iron homeostasis in each of their organs, tissues, cells and organelles. A few of the genes involved in iron homeostasis in plants have been identified recently, and we used some of th

20. Neutron tomography using projection data obtained by Monte Carlo simulation for nondestructive evaluation
This work present the application of a computer package for generating of projection data for neutron computerized tomography, and in second part, discusses an application of neutron tomography, using the projection data obtained by Monte Carlo technique, for the detection and localization of light materials such as those containing hydrogen, concealed by he

21. Espectroscopia de multicoincidencia aplicada ao estudo de moleculas
The main purpose of this thesis is to study selective photo-fragmentation processes of free molecules excited by synchrotron radiation using multi-coincidence spectros-copy. Below are summarized some original and important contributions of this work: 1) We show for the first time experimental evidences of ultrafast dissociation in water molecule after O1s ®

22. Ponte miocardica : considerações a proposito de 60 casos necropsiados
We studied sixty patients who underwent necrospy at University Hospital of PUCCAMP, which hearts presented myocardial bridges on the coronary artery branches. The objective of this work were: 1.The anatomic-pathologic study of the hearts. 2.The general and anatomic study of the myocardial bridges, including: bridge frequency, age, sex, race of the patientes;

23. Discrete domains mediate the light-responsive nuclear and cytoplasmic localization of Arabidopsis COP1.
The Arabidopsis CONSTITUTIVE PHOTOMORPHOGENIC1 (COP1) protein plays a critical role in the repression of photomorphogenesis during Arabidopsis seedling development. We investigated the control of COP1 partitioning between nucleus and cytoplasm, which has been implicated in the regulation of COP1 activity, by using fusion proteins between COP1 and beta-glucur

24. Characterization of the requirements for localization of phytochrome B to nuclear bodies
Phytochromes are red- and far-red-sensing photoreceptors that detect the quantity, quality, and duration of light throughout the entire life cycle of plants. Phytochromes accumulate in the cytoplasm in the dark. As one of the earliest responses after light illumination, phytochromes localize to the nucleus where they become associated with discrete nuclear b
