1. TÉCNICAS PARA REDUÇÃO DE CONSUMO EM CONVERSORES ANALÓGICO-DIGITAIS POR APROXIMAÇÃO SUCESSIVA E COMPARTILHAMENTO DE CARGA / TECHNIQUES FOR POWER REDUCTION IN SUCCESSIVE APPROXIMATION CHARGE SHARING ANALOG-TO-DIGITAL CONVERTERS
As novas tendências e tecnologias emergentes motivam o projeto de conversores analógico-digitais (ADCs) que precisam suprir especificações cada vez mais restritivas. Nesse contexto, uma métrica de projeto que é constantemente forçada em direção à redução é o consumo de potência, fato esse que leva à concepção de melhorias tanto em nível arq

2. Análise e proposta de melhoria do processo de previsão de demanda em uma pequena empresa do setor de cosméticos
Nowadays, even small-sized enterprises are investing in integrated management systems, called ERP (Enterprise Resource Planning), as a way to solve planning problems and to better control their cash flow. However, these enterprises end up neglecting one of the main inputs to improve the PPC (Production Planning and Control): the demand forecast. Thus, planni

3. Transmissões de vídeo ao vivo geradas por usuários: caracterização e análise
In the past few years, we have observed a huge revolution in terms of the way we create and distribute video on the Internet. With the popularization of digital cameras and with the increase of Internet access speeds, video content creation and distribution on the Internet has grown considerably. There are a number of recently created companies which offer t

4. Práticas do Psicólogo em Instituições Públicas de Saúde: o cuidado para com outro. / Psychologists Practice in the public health institutions: the care for the other
The psychologist takes up the challenge of fitting into the public health services, more precisely into the general non-psychiatric institutions characterized as an specific locus of practice and comprehension of the issues related to the continuum health-illness. However, acting on the complex field of collective health imposes to this professional a review

5. Espectroscopia e transferÃncia de energia em eidros La2O3-Nb2O5-B2O3
Glasses are amorphous materials with structures that can, in general, be described by a random non-periodic network model. Although for many glasses, mainly silicates, this model is appropriate, there are systems that present short and medium-range order (first and second coordination spheres) for which more sophisticated models are needed to describe their

6. Fibroblast growth factors share binding sites in heparan sulphate
HS (heparan sulphate) proteoglycans bind secreted signalling proteins, including FGFs (fibroblast growth factors) through their HS side chains. Such chains contain a wealth of differentially sulphated saccharide epitopes. Whereas specific HS structures are commonly believed to modulate FGF-binding and activity, selective binding of defined HS epitopes to FGF

7. Los Angeles Free-Net: an experiment in interactive telecommunication between lay members of the Los Angeles community and health care experts.
The Los Angeles Free-Net, an interactive community information resource, was established in part to help community members become more effective consumers of health care services. By providing timely, expert answers to anonymously asked medical questions at no charge, we hope to decrease unnecessary physician-patient encounters, encourage effective preventiv

8. Antigenicity of Campylobacter jejuni flagella.
We studied the antigenicity of a wild-type flagellate and motile (F+M+) Campylobacter jejuni strain (81116) and two daughter mutants, one flagellate and immotile (F+M-) and one aflagellate and immotile (F-M-). By sodium dodecyl sulfate-polyacrylamide gel electrophoresis of acid-extracted surface proteins, a 63-kilodalton (kDa) band identified from sheared fl

9. Does sharing the cost of a bicycle helmet help promote helmet use?
OBJECTIVE: To determine whether asking for a $5.00 donation for bicycle helmets, compared with distribution free of charge, would affect helmet use among children receiving helmets and an educational intervention from public health clinics. SETTING: Six public health clinic sites in King County, Washington. METHODS: Six participating clinic sites were random

10. Automated Purification and Suspension Array Detection of 16S rRNA from Soil and Sediment Extracts by Using Tunable Surface Microparticles
Autonomous, field-deployable molecular detection systems require seamless integration of complex biochemical solutions and physical or mechanical processing steps. In an attempt to simplify the fluidic requirements for integrated biodetection systems, we used tunable surface microparticles both as an rRNA affinity purification resin in a renewable microcolum

11. Translation initiation factor 5A and its hypusine modification are essential for cell viability in the yeast Saccharomyces cerevisiae.
Translation intitiation factor eIF-5A (previously named eIF-4D) is a highly conserved protein that promotes formation of the first peptide bond. One of its lysine residues is modified by spermidine to form hypusine, a posttranslational modification unique to eIF-5A. To elucidate the function of eIF-5A and determine the role of its hypusine modification, the
