1. High Efficiency Continuous Inverse Class-F Power Amplifier with Modified Current Waveform
Abstract Continuous inverse class-F (CICF) is a recent mode of harmonically-tuned RF power amplifiers used to extend the operating bandwidth of the conventional narrowband class-F−1 power amplifier by producing variable set of drain current waveforms and load admittances that give the same operating efficiency. In this work, a new approach of analysis is d

2. Impact of local conditions and machine management on grape harvest quality
ABSTRACT: Since its inception approximately 50 years ago, the grape harvester has been one of the machines responsible for the expansion of viticulture in the world. In Spain, harvesters were introduced in the 1990s (there are now approximately 3,000 machines there as of 2017), while they were introduced in Brazil in 2010. Harvest mechanization requires spec

3. FormulaÃÃo MatemÃtica para CÃlculo de VariaÃÃo de ConcentraÃÃo em Escoamento EstacionÃrio / Mathematical Formulation For The Calculation Of Changes Of Concentration In Stationary Flow.
The main aim of this research is to evaluate a variation of concentration between the affluent and effluent in a biophysical or physicochemical system. The theoretical system of references used here was based upon a differential equation of steady flow, involving a chemical kinetics and a longitudinal dispersion, in which there is a number of sufficiently lo

4. Tratamento de efluentes em lagoas de estabilização : uma estudo de caso em indústria de laticínio / Sewage treatment in stabilization ponds: a case study in diary industry
O aumento da inserção de diversas indústrias na região sudeste do Estado do Pará tem originado alterações nas condições ambientais dessa região. Os efluentes gerados nas indústrias de laticínios em termos de poluição hídrica tem um alto teor de material orgânico presente em sua composição. As lagoas de estabilização são tradicionalmente

5. Apreçamento racional de mercadorias utilizando modelo de valor presente para o boi gordo no período de 2001 a 2008
Campbell and Schiller (1987) proposed, within the scope of econometric analysis and cointegration, a powerful tool that enabled the present value model tests to also test market rationality and efficiency. The opportunity offered by the present value model of a substantial and settled fundamental value theory together with a powerful tool kit of empiricaleco

6. A EXPERIÊNCIA DO USUÁRIO COMO VIA DE RE-SIGNIFICAÇÃO DAS PRÁTICAS PSICOLÓGICAS NA REDE PÚBLICA DE SAÚDE / THE USER´S EXPERIENCE AS RE-SIGNIFICATION WAY FOR PSYCOLOGICAL PRATICES IN HEALTH SERVICES
It`s not rare among the studies developed with the users of national health assistance in the Unified System of Health (SUS) to discuss about adequacy and efficiency of clinical performance patterns used lo assist its demand. Theoretical and practical approaches applied lo clinical procedures for comprehension and problematization of suffering do not seem sa

7. Desenvolvimento sustentavel : uma analise do alcool como alternativa energetica
World energetic matrix based on combustible fossils, more importantly oil has shown signs of unsustainability. The reasons for this are related to both production structure, which needs to be diversified as to incorporate new sources of energy, and also to the actual pattern of consumption. There is plenty of evidence to suggest that humankind evolution will

8. Evaluation of counting error due to colony masking in bioaerosol sampling.
Colony counting error due to indistinguishable colony overlap (i.e., masking) was evaluated theoretically and experimentally. A theoretical model to predict colony masking was used to determine colony counting efficiency by Monte Carlo computer simulation of microorganism collection and development into CFU. The computer simulation was verified experimentall

9. Growth Kinetics and Yield Coefficients of the Extreme Thermophile Thermothrix thiopara in Continuous Culture
Thermothrix thiopara did not appear to be stressed at high temperature (72°C). Both the actual and theoretical yields were higher than those of analogous mesophilic sulfur bacteria, and the specific growth rate (μmax) was more rapid than that of most autotrophs. The specific growth rate (0.58 h−1), specific maintenance rate (0.11 h−1), actual molar gro
