The aim of this study was to evaluate crude extracts and fractions from leaves and stems of Lippia thymoides and to validate their use in folk medicine. In vitro antioxidant and antimicrobial activities and in vivo wound healing in rats, baker yeast-induced fever in young rats, and acute oral toxicity in mice assays were realized. The crude extracts and(More)
In a number of applications, it is necessary a network which could provide well-defined impedance values at different frequencies, that is a multiband impedance matching network. In this paper, we present a novel approach for dual-band impedance matching network design using multiresonant circuits. These multiresonant circuits provide short and open circuit(More)
In this paper, the concept of block reuse is applied to design a dual-band power amplifier. The amplification cell is shared for each frequency band and the impedance matching networks are designed making use of switchless multiresonant circuits. The target frequencies are those of the ISM band, 433 and 915 MHz. In order to obtain a good compromise between(More)
