13. Estudo genético de populações caprinas locais e exóticas através de marcadores microssatélites
The aim of the present study was develop a panel of microsatellites for testing paternity in goats as an aid for conservation and improvement programs for local breeds. A total of 381 animals from 10 goat populations [six local Brazilian ecotypes/breeds (Azul, Canindé, Graúna, Marota, Moxotó and Repartida) and four exotic breeds currently used in Brazil (

14. Prevalência de enterococos isolados de frangos caipiras em diferentes regiões do Distrito Federal
It was studied whether vancomycin-resistant enterococci (VRE) colonize poultry raised without receiving antimicrobial growth promoters (AGP), in non-intensive production systems. A total of 200 cloacal swabs were colleted in farms (n=40) of eight different regions of the Distrito Federal. After selective isolation, the typical enterococcal colonies were subm

15. Banco de filtros e wavelets sobre corpos finitos
Filter banks and wavelets are tools of Engineering, dened over complex elds, with many applications. This dissertation introduces the theory of lter banks and wavelets dened over nite elds, over cyclical and noncyclical structures. The problem of dening two-channel lter banks and wavelet decompositions over elds of characteristic two was solved, thereby prov

16. Preimplantation genetic diagnosis of Von Hippel-Lindau disease cancer syndrome by combined mutation and segregation analysis
Von Hippel-Lindau (VHL) disease is an autosomal dominant cancer syndrome, associated with the development of tumors and cysts in multiple organ systems, whose expression and age of onset are highly variable. The VHL disease tumor suppressor gene (VHL) maps to 3p25-p26 and mutations ranging from a single base change to large deletions have been detected in pa

17. Desenvolvimento e aplicação de polimorfismos de inserção: deleção do cromossomo x em genética forense
Nowadays the human genetic identification its based on the utilization of a set of autosomal markers, the microsatellites, which fulfils the majority of the forensic genetic labs requirements. However, there are some situations when that the usual autosomal microsatellites dont always offer good results. Those situations include cases where the genetic sampl

18. MultiplexaÃÃo por DivisÃo em MultirresoluÃÃo: um novo sistema baseado em wavelets / Multiresolution division multiplex: A new wavelet - based system
A new multiplex scheme is introduced, which is based on Mallatâs multiresolution formulation of wavelet systems. After the presentation of the basic tools for the development of this work, the system is introduced and a number of schemes is shown, with different configurations, so as to illustrate the potential and versatility of this new multiplex approach

19. O processo de migração de sistemas corporativos de comunicação TDM para plataformas convergentes IP com preservação de ativos
The aim of this elaboration is to present a study of the migration process involved transforming the digital PBX (Private Branch Exchange), TDM (Time Division Multiplex), SPC (Stored Program Control) based platforms of corporate communications on technology to converged IP (Internet Protocol) systems supported by the TCP/IP (Transmission Control Protocol/Int

20. Caracterização e análise de desempenho dos amplificadores ópticos Raman discretos em sistemas de comunicações ópticas na banda O
The optical amplifier has improved the optical communication systems because they lead to an increase in transmission capacity of medium and long haul optical systems, with technological advantages over electronic regenerators. The optical amplifier are relatively simple to deploy and can be used in optical links without any troubles regarding signal transmi

21. Medição e simulação de conversor em comprimento de onda com amplificador optico a semicondutor / Measurements and simulations of wavelenght converter based on semiconductor optical amplifier
The use of wavelenght-division multiplex (WDM) optical networks is a solution for the data-rate increasing in telecommunications systems. For a good performance of such networks, the use of wavelength converter based on semiconductor optical amplifier is important, since this one allows all-optical signal processing, as well as more flexibility in the spectr

22. Receptores MIMO baseados em algoritmo de decomposiÃÃo PARAFAC / MIMO receptors based on PARAFAC decomposition algorithm
This work deals with the application of multi-way analysis to the context of signal processing for wireless communications. A tensor decomposition known as PARAFAC (PARAllel FACtors) is considered in the design of multiple-input multiple-output (MIMO) receiver for a wireless communication system with Spread Spectrum codes. We propose two supervised PARAFAC-b

23. SISTEMAS DE MODULAÇÃO EM ÂNGULO-DEMODULADORES COM EXTENSÃO DE LIMIAR / ANGLE MODULATED SYSTEMS-DEMODULATORS WITH THRESHOLD EXTENSION
Angle modulation systems are analysed. Corresponding theoretical results are to experimental results and usual procedures connected to these systems. Power spectral density of a multiplex signal angle modulated carrier is compared to usual approximations, which shoe to be rather satisfactory. Still for a multiplex signal as modulating signal threshold improv

24. Evaluation of automated COBAS AMPLICOR PCR system for detection of several infectious agents and its impact on laboratory management.
We evaluated the COBAS AMPLICOR (CA) PCR system (Roche Diagnostic Systems) designed for automated PCR amplification and detection of nucleic acids from infectious agents in clinical samples. The Roche AMPLICOR microwell plate (MWP) PCR was the reference method. CA amplifies target nucleic acid, captures the biotinylated amplification products by using magnet
