Seed germination of two Syagrus species native to Brazil
(2013-07-15)
Palm species native to Brazil such as Syagrus picrophylla and S. schizophylla have great ornamental value and for this reason are much demanded for use in landscape. Its propagation is by seeds and often presents considerable ...
Dimensionamento de estruturas de aço em situação de incêndio
(Universidade Federal de Minas GeraisUFMG, 2000-08-11)
The fire design of steel structures has just recently called attention frompublic authorities and researchers in Brazil. Starting from researches developed in some universities in 1995, it was made a code about the subject ...
Design of operational transconductance amplifier with Gate-All-Around Nanosheet MOSFET using experimental data from room temperature to 200 °C
(2022-03-01)
In this work, a Gate-All-Around Nanosheet transistor (GAA-NSH) is used to design an operational transconductance amplifier (OTA) operating from room temperature to 200 °C. A simulation model for the transistor was created ...
An Elitist Non-Dominated Multi-Objective Genetic Algorithm Based Temperature Aware Circuit Synthesis
At sub-nanometre technology, temperature is one of the important design parameters to be taken care of during the target implementation for the circuit for its long term and reliable operation. High device package density ...

(2013-08-15)
The Phoenix roebelenii O'Brien is one of the most used plants in the Brazilian landscape. The work aimed to study the effect of different fruit harvesting locations, associated with seven temperature conditions, on the ...
Performance of differential pair circuits designed with line tunnel FET devices at different temperatures
(2018-06-06)
This work studies differential pair circuits designed with Line tunnel field effect transistors (TFETs), comparing their suitability with conventional Point TFETs. Differential voltage gain (A d), compliance voltage and ...
Kinetic study of the photo-Fenton degradation of formic acid: Combined effects of temperature and iron concentration
(Elsevier, 2009-02)
This study is focused on the kinetic modelling of the Fenton and photo-Fenton degradation of a model pollutant (formic acid) in aqueous solution, for relatively low iron concentrations (1–9 ppm). The reaction rate expressions ...
Germination and emergence of trumpet flower (Tecoma stans) under different environmental conditions [Germinação e emergência de amarelinho (Tecoma stans) sob efeito de diferentes condições ambientais]
