1. Impact of Alloy Composition and Thermal Stabilization on Martensitic Phase Transformation Structures in CuAlMn Shape Memory Alloys
Alloys of CuAlMn are known as cheap, high strength shape memory alloys with an excellent damping capacity within their austenitic-martensitic phase transformation, compared to alloy systems like NiTi, CuZnAl or MnCu. But CuAlMn alloys have disadvantage due to generation of voids by a high shrinkage which further increases the existing proneness to stress cra

2. Melhoramento de trigo para tolerância ao calor e qualidade de grãos / Wheat breeding for heat tolerance and grain quality
A grande extensão da região dos cerrados do Brasil-Central é uma área estratégica para o desenvolvimento da cultura do trigo. Contudo, nessa região o excesso de calor constitui o principal fator de redução no potencial produtivo. Além da tolerância ao estresse provocado pelo calor, a qualidade tecnológica dos grãos é de extrema importância no m

3. InteraÃÃo transitÃria entre transformadores de potencial capacitivos e linhas de transmissÃo: uma contribuiÃÃo para minimizar falhas
Coupling capacitor voltage transformers (CCVT) are widely used in power systems for monitoring, protection relays and control aplications. Failure of this equipment may cause unexpected outages of transmission lines (TL), which may result in severe penalties as imposed by the regulatory agency of the government. This fact requires speeding maintenance proced

4. Relação entre temperatura timpânica, cortisolemia e o estado emocional em gatos domésticos (Felis catus) / The relations among tympanic temperature, cortisolemie and the emotions in domestic cats (Felis catus)
The cat is interesting specie for studies of emotions due to its stoic behavior and to its physiological particularities. Cats easily get stressed. Routine procedures as exposition to an unknown environment can produce stress in these animals. A traditional indicator of stress is the serice cortisol, the main glicocorticoid of felines. The relation between p

5. Induction and selection of Eucalyptus urophylla cell lines resistant to thermic and hydric stresses / Indução e seleção de linhagens celulares de Eucalyptus urophylla para tolerância aos estresses hídrico e térmico
This work aimed to assess a possible relation between hight temperature and improvement in drought tolerance, as well as identify and select Eucalyptus urophylla cell lines under physiological and biochemical aspects. Callus obtained from hypocotyl of Eucalyptus urophylla and cultivated in N7 medium (SIMOLA, 1985) with the addition of 5mg.L-1 of Picloram wer

6. Pré-condicionamento em sementes de Cassia excelsa Schrad.
Cassia excelsa is a woody species commun in cerrado and srubland of brazilian northeast, known by cassia-do-nordeste. It could be used in landscape place and due to small size is used in street arborization, and could be recommended to recomposition of degradated areas. The aim of this work was to extend the knowlege about the ecophysiological behaviour, wit
