1. Lowering costs for large-scale screening in psychosis: a systematic review and meta-analysis of performance and value of information for speech-based psychiatric evaluation
Objective: Obstacles for computational tools in psychiatry include gathering robust evidence and keeping implementation costs reasonable. We report a systematic review of automated speech evaluation for the psychosis spectrum and analyze the value of information for a screening program in a healthcare system with a limited number of psychiatrists (Maputo, M

2. Psychometric properties of the WHOQOL-SRPB BREF, Brazilian Portuguese version
Objective: To test the reliability and the discriminant and convergent validity of the abbreviated Brazilian Portuguese World Health Organization’s Quality of Life Instrument – Spirituality, Religion, and Personal Beliefs module (WHOQOL-SRPB BREF). Methods: In a sample of 404 individuals, we applied a general questionnaire, the WHOQOL-BREF, the long-fo

3. Relationship between viral load and behavioral measures of adherence to antiretroviral therapy in children living with human immunodeficiency virus in Latin America
Few studies have examined antiretroviral therapy adherence in Latin American children. Standardized behavioral measures were applied to a large cohort of human immunodeficiency virus-infected children in Brazil, Mexico, and Peru to assess adherence to prescribed antiretroviral therapy doses during the three days prior to study visits, assess timing of last m

4. Uma nova abordagem de rastreamento do ponto de máxima potência em painéis fotovoltaicos
The photovoltaic energy offers known advantages, however, it has yet to overcome some challenges, mainly the low efficiency of conversion of the photovoltaic panels. Besides the development of new materials, it still continues very important to increase the conversion efficiency through the maximization of the input solar radiation and the optimization of th

5. Julia sets are uniformly perfect
We prove that Julia sets are uniformly perfect in the sense of Pommerenke (Arch. Math. 32 (1979), 192-199). This implies that their linear density of logarithmic capacity is strictly positive, thus implying that Julia sets are regular in the sense of Dirichlet. Using this we obtain a formula for the entropy of invariant harmonic measures on Julia sets. As a

6. NONLINEAR DYNAMICS, INSTABILITY AND CONTROL OF STRUCTURAL SYSTEMS WITH MODAL INTERACTION / DINÂMICA NÃO-LINEAR, INSTABILIDADE E CONTROLE DE SISTEMAS ESTRUTURAIS COM INTERAÇÃO MODAL
The aim of this thesis is to study the influence of coupled buckling modes on the static and particularly on the nonlinear dynamic behavior of structural components liable to buckling. For this, two discrete two degrees of freedom models known for their complex nonlinear behavior are selected: the well-known Augusti¿s model and a simplified model of cable-s

7. Análise comparativa da amplitude de vibração das pregas vocais e do coeficiente de contato durante a emissão da vogal /ɛ/ prolongada e vibração sonorizada de lábios e língua / Comparative analysis of the amplitude of vibration of the vocal folds and the coefficient of contact during the utterance of the sustained vowel / ? / and the lips and tongue trills
Exercises of audible vibration are widely used for the treatment of dysphonia and vocal preparation of professional voice users. There is little research done studying vocal physiology during exercise. The aim of this study is to compare the differences in cordal vibration during the exercises of lips and tongue trills and the sustained vowel / ? / as to the

8. Logística reversa de pós-venda para alimentos derivados de carne e leite : análise dos retornos de distribuição
Reverse logistics has conquered more importance and space in the companies logistics operation, mainly for its economic potential, but also for the change in the customers consumption culture and for the increase of the importance of environmental preservation. However, the lack of studies in this direction makes it difficult to visualize the advantages of t

9. Generalizations of the Riesz Representation Theorem / Generalizações do teorema de representação de Riesz
Dados um espaço de medida (X;A;m) e números reais p,q>1 com 1/p+1/q=1, o Teorema de Representação de Riesz afirma que Lq(X;A;m) é o dual topológico de Lp(X;A;m) e que Loo(X;A; m) é o dual topológico de L1(X;A;m) se o espaço (X;A;m) for sigma-finito. Observamos que a sigma-finitude de (X;A;m) é condição suficiente mas não necessária para que Loo

10. Impacto da utilização de tecnicas de lifting explorando diferença entre ferramentas interpretada e compilada na velocidade computacional da codificação wavelet de imagens estaticas / Impact of using lifting techniques to explore the differences between interpreted and compiled tools in the computational speed of wavelet static image coding
The field of analysis and compression of images has been received special attention of the scientific community because of including in the main systems of digital TV, satellite communications and mobile communications. In this context, the Discrete Transform Wavelet (TWD) arise how a powerful tool and its many advantages allowed your insertion in important

11. MODELO DE PROGRAMAÇÃO ESTOCÁSTICA PARA O PLANEJAMENTO ESTRATÉGICO DA CADEIA INTEGRADA DE PETRÓLEO / A STOCHASTIC PROGRAMMING MODEL FOR THE STRATEGIC PLANNING OF THE OIL SUPPLY CHAIN
The oil industry is one of the most important and dynamic in Brazil. As the oil industry naturally integrated, we need an appropriate strategic planning to the oil supply chain that consider all its processes, such as oil production, refining, distribution and refined products marketing. Moreover, the oil industry is susceptible to various uncertainties rega

12. Os créditos de emissões atmosféricas reduzidas e a responsabilidade civil ambiental
Although the problem related to the weather change has been widespread only in the last decades, it is not recent the concern of the international community in the adoption of measures for the mitigation of this change in the ecosystem balance. The Kyoto Protocol, however, comes as the concrete awareness of the need of acting towards the reduction of the gre
