1. Automatic identification of tuberculosis mycobacterium
Introduction According to the Global TB control report of 2013, “Tuberculosis (TB) remains a major global health problem. In 2012, an estimated 8.6 million people developed TB and 1.3 million died from the disease. Two main sputum smear microscopy techniques are used for TB diagnosis: Fluorescence microscopy and conventional microscopy. Fluorescence micro

2. Propagation of waves in micropolar generalized thermoelastic materials with two temperatures bordered with layers or half-spaces of inviscid liquid
The aim of the present paper is to study the propagation of Lamb waves in micropolar generalized thermoelastic solids with two temperatures bordered with layers or half-spaces of inviscid liquid subjected to stress-free boundary conditions in the context of Green and Lindsay (G-L) theory. The secular equations for governing the symmetric and skew-symmetric l

4. Sobre subvariedades totalmente reais / On totally real submanifolds
Subvariedades analÃticas complexas e totalmente reais sÃo duas classes tÃpicas dentre todas as subvariedades de uma variedade quase Hermitiana. Neste trabalho procuramos dar algumas caracterizaÃÃes de subvariedades totalmente reais. AlÃm disso algumas classificaÃÃes de subvariedades totalmente reais em formas espaciais complexas sÃo obtidas.

5. Sobre a geometria de imersÃes isomÃtricas em variedades de Lorentz conformemente estacionÃrias / On the geometry of varieties of isometric immersions in Lorents stationary conformally
In this thesis we study several aspects of the geometry of conformally stationary Lorentz manifolds and, more particularly, of generalized Robertson-Walker spaces, under the presence of a closed conformal vector field. We initiate by focusing our study on the r-stability and on the strong r-stability of closed spacelike hypersurfaces of conformally stationar

6. The stability theorem of Lichnerowicz for holomorphic applications in Kahler manifolds / O teorema de estabilidade de Lichnerowicz para aplicaÃÃes holomorfas em variedades Kahler
Our goal in this work is to present a theorem due to A. Lichnerowicz, which guarantees stability from applications holomorphic or antiholomorphic with compact domain between Kahler manifolds.

7. Codigos esfericos em toros planares / Spherical codes on flat torus
Spherical codes in Euclidean spaces are finite sets of points on the surface of a multidimensional sphere and have been widely studied in connection with the signal transmission over a Gaussian channel. For this purpose one fundamental issue is to maximize the minimum distance between two code points, what is strongly related to the more general problem of s

8. Historical and member environmental aspects related to the occurrence of schistosomiasis in the municipality of Pindamonhangaba, SP. / Aspectos históricos e sócio ambientais relativos à ocorrência da esquistossomose no município de Pindamonhangaba - SP
The urbanization and the occupation of spaces in a disordered way can contribute for important changes in the environment, favoring the pollution and the use of natural resources, and contributing for the proliferation of some parasitic diseases, in special waterborne and vector-borne diseases. Schistosomiasis, one of these diseases, is caused by a trematode

9. Dualidade de espaços de Hardy com valores vetoriais / Duality of vector valued Hardy spaces
In this work we study the vector-valued Hardy spaces Hp(Δ ; F) (1 = p = 8). We also study the Banach spaces with the properties ARNP and RNP and the UMD spaces. We also study the Banach spaces with the RNP and ARNP properties, and also the UMD spaces. By following the approach of Taylor [36],[37] in the scalar-valued case, we prove that, when F and F ha

10. Información, conocimiento y percepción sobre el riesgo de contraer el dengue en Argentina: dos experiencias de intervención para generar estrategias locales de control
With the objectives of dengue prevention, health promotion, and action-based research, two experiments were conducted in pilot areas of Buenos Aires and Vicente López, Argentina. In each area, community, government, and non-governmental references were identified. The study included an entomological survey (with ovitraps), environmental survey (with field o

11. Combinação de múltiplos classificadores para reconhecimento de face humana
Lately, the human face object has been exploited by the advent of systems involving biometrics, especially for applications in security. One of the most challenging applications is the problem of human face recognition, which consists of determining the correspondence between an input face and an individual from a database of known persons. The process of fa
