13. Uma metodologia de projetos para circuitos com reconfiguração dinâmica de hardware aplicada a support vector machines. / A design methodology for circuits with dynamic reconfiguration of hardware applied to support vector machines.
Systems based on general-purpose processors are characterized by a flexibility to design changes, although with a computational performance below those based on optimized dedicated circuits. The implementation of algorithms in reconfigurable devices, known as Field Programmable Gate Arrays, FPGAs, offers a solution with a trade-off between the processors fle

14. "Sistemas de análises químicas em fluxo explorando multi-impulsão e detecção espectrofotométrica: aplicação a formulações farmacêuticas e a extratos de solos" / Multi-pumping flow systems with spectrophotometric detection: application to analysis of pharmaceuticals and soil extracts
Multi-pumping flow systems (MP) utilize solenoid pumps as fluid propelling devices, which deliver pulsed flows. This feature was evaluated in relation to the design, operation and performance of the system, to the mixing conditions, and to the dispersion of the introduced solution. The general evaluation of the MP systems involved investigations about precis

15. Estudos de circuitos evolutivos aplicados ao reconhecimento de voz
This work presents some results of the application?s study of Evolvable Hardware (EHW) in the area of circuits design and voice recognition. Evolvable Hardware is able to change inner connections, using genetic learning techniques, adapting its own functionality to external condition changing. This technique became feasible by the improvement of electronics

16. Analise do processo de extrusão na industria de "PET-FOOD" para a aplicação de tecnicas de controle avançado / Review of the extrusion industry in the "PET-FOOD" for the application of advanced techniques of control
The present study informs about the main features of extrusion control processes, based on product-wet density and moisture. To comprehend the study, some background of the classic control theory is provided. The process complexity, provided by formation of a bio-polymer from carbohydrate-lipid-protein raw materials, requires analysis using statistical conce

17. Medical Library Service in the Hospital
Because of the extent of the medical literature and the wide-ranging interests of medical scientists, it is not feasible today for a hospital library to provide from its own shelves all of the books and journals that are requested by its doctor clientele. The suggested alternative is for the hospital library to select an appropriate medical research library

18. Stability of Antibiotics Used for Antibiotic-Lock Treatment of Infections of Implantable Venous Devices (Ports)
Antibiotic-lock is a treatment for catheter-related bloodstream infections in which a solution containing heparin and an antibiotic dwells in the lumen of the catheter or port. We tested the stability of vancomycin, cefazolin, ticarcillin-clavulanic acid, ceftazidime, or ciprofloxacin combined with heparin after incubation in vitro at 25 or 37°C for interva

19. Role for endovascular therapy in chronic mesenteric ischemia
Chronic mesenteric ischemia is a rare condition that is caused by stenosis or occlusion of the mesenteric arteries and usually manifests as abdominal pain. While surgical revascularization has been the standard treatment for symptomatic patients, recent advances in interventional devices and techniques have made endovascular treatment feasible and effective.

20. Ventricular assist devices as a bridge to cardiac transplantation. A prelude to destination therapy.
OBJECTIVE AND BACKGROUND: Ventricular assist devices (VADs) have been used for temporary circulatory support pending transplantation or recovery of the native heart. Outcome in 38 patients treated at the authors' institution with VADs pending transplantation was analyzed to provide information relevant to the future use of VADs as permanent implants. METHODS

21. Reproducible enzyme-linked immunosorbent assay with a magnetic processing system for diagnosis of toxoplasmosis.
An enzyme-linked immunosorbent assay with polycarbonate-coated iron beads as the solid phase and with magnetic processing devices was evaluated for the quantitation of antibodies to Toxoplasma gondii in human serum samples. Under the parameters and other basic conditions determined in this study, the assay was highly reproducible: coefficients of variation f

22. Charged-coupled detector sky surveys.
Sky surveys have played a fundamental role in advancing our understanding of the cosmos. The current pictures of stellar evolution and structure and kinematics of our Galaxy were made possible by the extensive photographic and spectrographic programs performed in the early part of the 20th century. The Palomar Sky Survey, completed in the 1950s, is still the

23. Use of a second transcatheter Rashkind arterial duct occluder for persistent flow after implantation of the first device: indications and results.
OBJECTIVE--To assess the efficacy, feasibility, and most appropriate timing of the implantation of a second Rashkind arterial duct occluder because of persistent flow after the first device. DESIGN--A prospective serial Doppler study of patients after the insertion of a Rashkind arterial duct occluder including a subgroup in whom a second device was implante

24. Primary transcatheter umbrella closure of perimembranous ventricular septal defect.
OBJECTIVES--The starting hypothesis was that some perimembranous ventricular septal defects can be closed safely and effectively with a Bard Rashkind double umbrella introduced through a long transvenous sheath. DESIGN--A descriptive study of all patients who underwent attempted transcatheter umbrella closure of a perimembranous ventricular septal defect. Th
