13. The ethics of competition and its heroes / A etica da concorrencia e seus herois
The main problem of this work is the understanding the reasons for the long journeys of work by executives of success. To do this, it was necessary a previous study on the recent transformations in the labor market and the increase on competition. The first chapter deals with the issue of individual competition in the context of we call "social closure." The

14. ANÁLISE DE MÚLTIPLAS VARIÁVEIS NO FECHAMENTO DE MINA ESTUDO DE CASO DA PILHA DE ESTÉRIL BF-4, MINA OSAMU UTSUMI, INB CALDAS, MINAS GERAIS.
The Osamu Utsumi belongs to Indústrias Nucleares do Brasil (INB), located in Caldas/MG, operated from 1982 to 1995, when the complete suspension of mining activities a processing of the uranium ore took place. Since then, the mine has an active maintaining system, which focus is the treatment of the acid drainage from the pit, waste dumps (locally called bo

15. Modelagem multiescala do acoplamento eletro-químico em um meio poroso argiloso com dependência do PH / Multiscale modeling of eletro-chemical couplings in clays including PH dependence
In this work we develop a three-scale mathematical modeling to describe electro-chemical couplings in clays using the asymptotic homogenization procedure of periodic structures. We consider the porous medium composed of kaolinite particles saturated by an electrolyte solution of water-solvent and four ionic solutes monovalents Na+, H+, Cl-, OH-At the nanosca

16. Estudo da geração de biogas no aterro sanitario Delta em Campinas - SP
Disposal of waste into landfills represents one of the most important problems in urban sites, particularly in Brazil where the use of "open dumps" is still very common. Uncontrolled emission of biogas produced by anaerobic decomposition of the organic matter can be a local environmental hazard causing vegetation damage, unpleasant odors and may form explosi

17. An unstructured grid approach to the solution of axisymmetric launch vehicle flows.
A study of the flowfield around axisymmetric launch vehicles in different flight conditions and configurations is performed in this work. Particularly, the VLS second stage flight configuration is analyzed considering the case with and without a propulsive jet in the vehicle base. Among the different cases considered for this configuration there are inviscid

18. Modelagem semi-analitica pseudo tridimensional de propagação e fechamento de fraturas induzidas em rochas
This investigation describes a semi-analytical model which simulates fracture propagation in petroleum reservoir rocks. The model permits evaluating the three fracture dimensions parameters (width, height and length) during propagation. Like other pseudo 3D models, some assumptions are used to solve the fracture three-dimensional propagation problem, such as

20. Directed Gap Closure in Large-Scale Sequencing Projects
A problem in many sequencing projects is the final closure of gaps left in the clone libraries, which serve as templates for sequencing, because of uncloned or unclonable genomic areas. By use of the Xylella fastidiosa genome as a test system, we present here an approach to generate, in a directed manner, sequence information from those gaps. We suggest usin

21. Echocardiographic differentiation of hypertensive heart disease and hypertrophic cardiomyopathy.
The clinical differentiation of hypertensive heart disease from hypertrophic cardiomyopathy usually presents no problem but it is less clear whether an echocardiographic distinction can always be made and, if so, what those echocardiographic criteria of difference are. It can be inferred from recent publications that when echocardiographic criteria for hyper

22. Transascending aortic intraaortic balloon insertion with delayed sternal closure: A retrospective analysis
Intraaortic balloon pumping (IABP) is an established therapeutic adjunct in the treatment of postcardiotomy/infarction low cardiac output states. Although the common femoral or iliac arteries are the preferred sites for balloon insertion, severe arterial occlusive disease may preclude entry by these methods. To circumvent this problem, alternative methods of

23. The “Up-Down” Problem For Operator Algebras
It is shown that for any C*-algebra A of operators on a separable Hilbert space, there is, for each self-adjoint operator x in the strong closure of A, a sequence {xn} of self-adjoint operators, each of which is the strong limit of a monotone increasing sequence of self-adjoint operators from A, such that {xn} is monotone decreasing and strongly convergent t

24. Aorto-left ventricular communication after closure. Late postoperative problems.
The long-term follow-up of six patients operated on for aorto-left ventricular communication has been reviewed in detail. All had residual aortic regurgitation after the initial repair of the defect. It was severe in four and required repeated reoperation in three with ultimate aortic valve replacement. The failure of early repair to solve the haemodynamic p
