1. Alternative Igniters Based on Oxidant Salts for Microwave-Induced Combustion Method
In this work, solutions of oxidant salts were evaluated as alternative to nitrate solution for the ignition step in microwave-induced combustion (MIC) method. Aqueous solutions of KClO4, K2Cr2O7, KMnO4 and K2S2O8 in several concentrations were evaluated and it was observed that the ignition was dependent on the concentration and type of igniter solution. Mor

2. Uncooled detectors of continuum terahertz radiation
THz continuum spectral photometry has new and unique applications in different civil and military areas presenting a number of distinctive advantages on the well known microwaves or mid- to near-infrared technologies. THz sensing is essential to investigate the emission mechanisms by high energy particle acceleration processes. Technical challenges appear to

3. Tetraciclinas em medicamentos veterinários e produtos lácteos. / Tetraciclinas em medicamentos veterinarios e produtos lacteos.
The objectives of the present study were establish and validate analytical methods (using flow injection analysis - FIA and high performance liquid chromatography - HPLC) for the determination of oxitetracycline (OTC), doxycycline (DC) and tetracycline (TC) in veterinarians drugs and foods (milk and yoghurt). As well as evaluating the stability of these tetr

4. Estimativas da temperatura e umidade do dossel na Floresta Amazônica, utilizando dados de microondas do sensor SMMR do satélite Nimbus-7 / Estimations of temperature and humidity of the canopy in Amazon Forest using microwave data from SMMR sensor of Nimbus-7 satellite
Obtiveram-se estimativas de umidade e temperatura da cobertura vegetal em mata de terra firme da regiao de Manaus (3$^{°}$ S, 60$^{°}$ W), durante as estacoes umida (abril/maio)e seca (julho/agosto)de 1985, as 12:00 e 24:00 horas local, a partir de dados radiométricos de microondas medidos por satélite, em conjunto com modelos de emissão de microondas.

5. Estimations of temperature and humidity of the canopy in Amazon Forest using microwave data from SMMR sensor of Nimbus-7 satellite / Estimativas da temperatura e umidade do dossel na Floresta Amazônica, utilizando dados de microondas do sensor SMMR do satélite Nimbus-7
The forest canopy humidity and temperature of the region of Manaus (3o S, 60° W) have been estimated for the 1985 wet (April-May) and dry (July-August) seasons at 12:00 and 00:00 local standard time, from spaceborne microwave radiometer, along with microwave emission models. The satellite data consist of SMMR (Scanning Multichannel Microwave Radiometer) Nim
