13. First brazilian consensus of advanced prostate cancer: recommendations for clinical practice
ABSTRACT Introduction Prostate cancer still represents a major cause of morbidity, and still about 20% of men with the disease are diagnosed or will progress to the advanced stage without the possibility of curative treatment. Despite the recent advances in scientific and technological knowledge and the availability of new therapies, there is still conside

14. COMPUTATIONAL STUDY OF THE INTERACTION BETWEEN INDENE PYRAZOLE AND CYCLIN DEPENDENT KINASE 2
Proteins have been traditionally out of reach of electronic structure methods. But with technological advances in the development of powerful computers and the need to extend the methods of computational chemistry to problems of biological interest, such as the rational design of drugs, new technologies in silico have been developed that allow to study conde

15. Development Accounting, the Elasticity of Substitution, and Non-neutral Technological Change
Nós aplicamos as técnicas de contabilidade do desenvolvimento em um amplo painel de países no período 1970-2014. Entretanto, nós desviamos da tradicional hipótese da Cobb-Douglas com progresso tecnológico Hicks-neutro, e assumimos uma tecnologia CES, que permite elasticidade de substituição constante, porém diferente da unidade, e progresso tecnol�

18. Convergence in information and communication technology (ICT) using patent analysis
Since the 1990s, information and communication technology (ICT) has been perceived as the critical technology for economic development, and the ICT industry itself has been growing exceptionally fast. Moreover, technology convergence in ICT has received particular attention. ICT innovations diffuse into existing products and thus come to form a new integral

19. Metallurgical alterations in the surface of steel cavities machined by EDM
The electrical discharge machining (EDM) is a process characterized by high thermal demands, which tend to cause metallurgical changes in the surface of the workpiece [1-2]. This work aims to conduct a discussion of metallurgical changes in the surface of cavities obtained by the process of EDM in the machining of steel. Several variables were employed, such

20. Síntesis en medio poli-alcohólico y caracterización de Perovskitas BaHfO3 y BaZrO3
Perovskite materials (ABO3) present considerable technological interest, their properties depend on the A and B elements. A variety of methods have been used for the elaboration of perovskite materials. In the present paper we present the results of the BaHfO3 and BaZrO3 obtained by polyol method. Inorganic salts of barium and hafnium or zirconium were disso

21. Liberal versus neo-developmental convention to growth: why has Brazil shown a poor performance since the 1980s?
The main goal of our paper is to provide analytical arguments to explain why Brazil has not been able to restore its long-term capacity for economic growth, especially compared with its economy in the 1950-1979 period (7.3 per cent per year on average) or even with a select number of emerging economies in the 1980-2010 period(6.7 per cent per year on average

22. Workplace learning strategies and professional competencies in innovation contexts in Brazilian hospitals
Competencies mobilized by service providers form an element of hospital services insofar as scientific and technological procedures that are part of the service become tangible. In view of the fact that hospitals have adopted Information and Communication Technologies (ICT), it would be logical to assume that learning contributes towards acquiring competenci

24. Espacio del producto y cambio estructural: un enfoque latinoamericano y una aplicación al caso uruguayo
This article immerses into the debate about the determinants of countries income level convergence, and states that the productive structure of a country is one of the most important of such determinants. A comparative study is performed, testing the potentiality for structural change for Uruguay and nine other countries with a commercial specialization that
