1. The antimicrobial effect of 0.1 ppm ozonated water on 24-hour plaque microorganisms in situ
Ozone is a known oxidant present in the atmosphere and is commercially produced by simple ozonizer machines. It is a powerful antimicrobial agent in its gaseous and aqueous forms. Ozone readily dissolves in water and retains its antimicrobial property even in the dissolved state. In this study, the effect of 0.1 ppm ozonated water was analyzed on 24-hour sup

2. Improved capacity of eccentric mechanical presses existing in Brazilian industry / Melhoria na capacidade de produção das prensas mecânicas excêntricas existentes na indústria brasileira
This work defines a methodology to improve the production capacity of the mechanical presses existing in the Brazilian industry. The eccentric mechanical presses with crank drive (connecting rod) are very simple machines for operation, but these presses use a lot of energy during the working cycle, partially due the fixed descent and rising speeds of the sli

3. VIABILITY STUDY OF THE OPERATIONAL PROCESS OF CATURRITA CENTRAL RESIDUES TREATMANT PLANT (CTRC) SANTA MARIA, RS / VIABILIDADE DO PROCESSO OPERACIONAL DA CENTRAL DE TRATAMENTO DE RESÍDUOS DA CATURRITA (CTRC) SANTA MARIA, RS
This approach identifies some physical characteristics of the residues and the operational procedures converning the destination of these residues at the Central of Residues Treatment of Caturrita (CTRC), located on the city of Santa Maria (RS). The CTRC is composed by unit of selection, unit of compostage and sanitary embarement, wich supports a population

5. Melhoramentos no algoritmo genético construtivo e novas aplicações em problemas de agrupamento / Constructivegeneticalgorithmimprovementsandnewclusteringproblemsapplications
Evolutionary Algorithms has been a research subject for decades and are based on evolving populations of possible solutions for a problem along generations. Genetic Algorithms belong to this group and many scientific works have registered their efficiency applied to combinatorial optimization problems. Recently, the Constructive Genetic Algorithm (CGA)has be

7. Mitochondrial Lon of Saccharomyces cerevisiae is a ring-shaped protease with seven flexible subunits
Lon (or La) is a soluble, homooligomeric ATP-dependent protease. Mass determination and cryoelectron microscopy of pure mitochondrial Lon from Saccharomyces cerevisiae identify Lon as a flexible ring-shaped heptamer. In the presence of ATP or 5′-adenylylimidodiphosphate, most of the rings are symmetric and resemble other ATP-driven machines that mediate fo

8. Universal energy principle of biological systems and the unity of bioenergetics.
Electronic energy (chemical bond energy) is the exclusive source of utilizable energy in biological systems. The release of this energy is mediated enzymically. The energy required to rupture a single covalent or ionic bond is prohibitively high under physiological conditions [in the range of 80-200 kcal/mol (1 kcal = 4.18 kJ)]. By the technique of the pairi
