Utilização do Intron Splice Site primer EI-1 na discriminação de leveduras contaminantes do processo de fermentação alcoólica

Neste trabalho, utilizamos o Intron Splice Site primer EI-1 para a análise do perfil de amplificação de diferentes espécies de leveduras consideradas contaminantes no processo de fermentação alcoólica, originadas de uma destilaria no Estado da Paraíba na safra 2004/2005. Foram realizadas as etapas analíticas para discriminação molecular das leveduras a partir da extração do DNA total, amplificação por PCR e análise do perfil genético. Os resultados obtidos indicam que o Intron Splice Site primer EI-1é muito eficaz na discriminação das diferentes espécies de Saccharomyces e não Saccharomyces, evidenciando padrões de bandas específicos para as leveduras analisadas. Este primer, por ser complementar a uma região muito conservada do genoma das leveduras, mostrou-se incapaz de uma discriminação intraespecífica. Isto demonstra a utilidade deste marcador no auxílio à taxonomia de leveduras.

Building-up influence: post-war industrialization in the State of Minas Gerais, Brazil

This paper examines the post-War industrialization process in the Brazilian State of Minas Gerais, focusing on one of its desirable outcomes, namely the capacity to generate growth through the impact of strong input-output linkages. This process is placed into historical perspective considering the ideas that permeate the economic development debate throughout the period of analysis. Changes in the regional economic structure are assessed through the use of three input-output tables for the years of 1953, 1980 and 1995. By adopting the fields of influence methodology as the analytical core, it is shown that the efforts towards the creation of a more integrated regional economy have generated stronger influence of the targeted sectors (metal products, transportation equipment, chemical, and services). However, structural changes also contributed to strengthen leakage in the system originated in traditional economic activities.

Building governance in the international financial system: Context and challenges

ABSTRACTThe international financial system has undergone deep changes since the 1970s and its stability cannot be reached in spite of actor's interests or the existence of countless coordination fora. Analyzing the system's incentive structure, one can note that its stability depends on the control of imbalances, which are not always harmful for States, creating, thus, a disturbing component in the quest for international financial management. Furthermore, non-state actors have acquired a disproportional share of power following financial globalization, escaping the control of States and of the international community.
