2. O fator de transcrição AtbZIP63 como integrador de sinais energéticos e estresses biótico/abiótico / The transcription factor AtbZIP63 as a integrator of energetic signals and biotic/abiotic stresses
A manutenção do balanço energético em plantas é de crucial importância para a otimização de seu crescimento e desenvolvimento em resposta às condições sempre flutuantes do meio. A energia obtida através da fotossíntese deve ser utilizada parcimoniosamente e dividida entre crescimento, desenvolvimento, armazenamento e respostas a estresses bióti

3. UtilizaÃÃo de promotores de crescimento em raÃÃo para frangos de corte / Use of growth promoters in feed for broiler
Two experiments were carried out to evaluate the effects of using distinct growth promoter over the energetic metabolism and performance of poultry farming. Two experimental diets (ND â normal diet according to nutritional requirements and RD â reduced diet, with 5% less of nutrients), supplemented or not with antibiotics and prebiotics from 1 to 10, 11 to

4. Invasive non-native species of fish in upper Paraná river Basin, Brazil: variations of caloric content in Cichla kelberi
O balanço energético em espécies de peixes pode ser influenciado por variações sazonais no crescimento e ciclo reprodutivo, consumo de alimento e condições ambientais. O objetivo desta pesquisa foi o de avaliar as variações energéticas em uma espécie piscívora introduzida, Cichla kelberi, no alto rio Paraná, analisando as variações do teor cal

5. Metabolism and brain cancer
Cellular energy metabolism is one of the main processes affected during the transition from normal to cancer cells, and it is a crucial determinant of cell proliferation or cell death. As a support for rapid proliferation, cancer cells choose to use glycolysis even in the presence of oxygen (Warburg effect) to fuel macromolecules for the synthesis of nucleot

6. Study of the termal decomposition of 2,2',4,4',6,6'- hexanitrostilbene
Abstract: 2,2’, 4,4’, 6,6’- hexanitrostilbene (HNS) is an energetic material, a nitroaromatic compound, with thermal and chemical stabilities, which is employed in the aerospace industry. In this work, the Arrhenius parameters (activation energy and pre-exponential factor) of thermal decomposition reaction were studied and the results were compared wit

7. Desempenho energético e caracterização dos sistemas de aquecimento de água de piscinas. / Energetic performance and characterization of swimming pool heating systems.
The aim of this research is to investigate the energetic performance of two distinct kinds of swimming pool heating systems: gas-fired and electric heat pump. A practical instrumentation research was prepared in these two indoor swimming pools, placed in the same location. Besides these, other four swimming pool, placed each in a different ambient in the cit

8. Alterações metabólicas e o papel da mitocôndria no processo de tumorigênese de astrocitomas humanos / Metabolic alterations and the role of mitochondria in tumorigenic process of human astrocytomas
Mitochondria has a key role in cell survival and death. Mitochondrial DNA (mtDNA) alterations, for example, amplification, homoplasmic mutation, deletion and depletion, and their clinical and pathological implications have been analyzed in human malignancies. In order to search for mitochondrial alterations associated to tumorigenesis, this study aimed to an

9. PRODUÇÃO DE ÁLCOOL COMBUSTÍVEL EM PEQUENA ESCALA: DESENVOLVIMENTO DA TECNOLOGIA DE DESTILAÇÃO APROPRIADA / APPROPRIATE DISTILLATION TECHNOLOGY DEVELOPMENT FOR ETHANOL FUEL PRODUCTION IN SMALL SCALE
A produção de álcool combustível em pequena escala, até 25L.h-1, enfrenta sérios problemas relativos à ineficiência inerentes a seus processos. O aumento de rendimento na etapa de destilação apresenta-se como uma maneira promissora de viabilizar técnica e economicamente as microdestilarias. Sendo esse o objetivo geral, propõe-se um destilador dif

10. Incidência de sedentarismo no tempo livre em professores de Educação Física da grande Goiânia
The sedentarism, as secondary risk factor, has been studied scientifically since 1950. But only in 1992 it has been recognized as primary risk factor (casual, major) to population morbimortality, mainly by cardiovascular diseases. According to cause/effect logic and epidemiologic studies, the sedentarism in leisure has been considered an independent variant

11. Carvão vegetal e siderurgia: de elo perdido a solução para um mundo pós-Kyoto / Charcol based iron &steelmaking: from primitive technological model to solution for a post-Kyoto world
In a global-warming-frightened world, the positive carbon balance of charcoal-based iron &steel making recovers it from a past outshined by the dominance of the large fossil fuel mills. Nevertheless, the risk of not being able to profit from the global decarbonization consensus is material, owing to the dependency on deforestation. This is true even being th

12. Estudos de alterações funcionais de macrofagos submetidos a hipoxia no modelo in vitro da leishmaniose / Studies of funcional alterations of macrophages submetted to hypoxia in ana in vitro model of leishmaniasis
Regions of low oxygen tension (hypoxia) are common features of inflamed/infected tissues. The analyses of cell phenotypic alterations by hypoxia are helpful for understanding of the pathological mechanisms and treatment resistance and for the development of cellular therapies. Macrophages, cells involved in the clearance of microorganisms from infected tissu
