Trajetória de Crescimento da Economia Brasileira e Mudança Estrutural de 1971 a 2008: uma interpretação a partir do Framework Space
No full textO objetivo do texto é analisar a trajetória de crescimento da economia brasileira dos anos de 1970 até 2008, considerando as flutuações do investimento e da produtividade como determinantes do comportamento dessa trajetória. Assim, identificamos e qualificamos diferentes fases ou caminhos de crescimento compondo a trajetória de longo prazo. O comportamento oscilatório dessa trajetória tem sido atribuído a conjecturas de várias naturezas; aqui enfatizaremos as mudanças nas políticas econômicas e seus efeitos sobre a estrutura produtiva via mudança estru- tural induzida que repercute na dinâmica observada. Apoiados na visão kaldoriana e neo-schumpeteriana introduziremos o Framework Space como instrumento de análise da dinâmica da trajetória de crescimento econômico do Brasil

Polimorfismos (g.16024A>G e g.16039T>C) do gene FASN relacionados à composição lipídica da carne em raças bovinas.
No full textUma das etapas dentro da caracterização genética das raças bovinas localmente adaptadas do Brasil tem sido a avaliação de polimorfismos em genes candidatos relacionados a características de interesse econômico visando promover o seu uso potencial e diversificado. Neste trabalho objetivou-se verificar a variabilidade genética de polimorfismos do gene FASN relacionados com a composição lipídica da carne. Os animais foram genotipados para os polimorfismos g.16024A>G e g.16039T>C do gene FASN pela técnica de PCR-RFLP. O haplótipo TW, associado ao aumento da relação de C18:1 na carne, foi mais frequente nos animais da raça Wagyu do que nas outras raças avaliadas. Dentre as raças localmente adaptadas, a Crioula Lageana e a Caracu apresentaram as maiores frequências do haplótipo TW. A alta variabilidade genética dos polimorfismos avaliados nas raças localmente adaptadas evidencia seu potencial de uso em programas de melhoramento genético. Considerando a alta variabilidade observada nas frequências gênicas dos polimorfismos do gene FASN, estudos envolvendo a associação de dados fenotípicos e genéticos são necessários para avaliar o efeito destes genes na variação da composição lipídica nas raças analisadas

No full textBrazil’s economy – 1971–2008. Growth patterns and structural change
No full textGrowth cycles are well documented and studied phenomena in the LDCs; in the case of Latin America, they are often related to the evolution of the conditions of international liquidity (Amado et al., 2007). But, in general, growth in such countries tends to be less stable than in developed ones, as those economies are often constrained by a variety of domestic and international constraints, among them, balance-of- payments constraints. This has been true also of our case study hereafter, the Brazilian economy: at the beginning of the 1960s and in the 1980s, and again, more recently, during the second half of the 1990s following the financial crises of Mexico in 1995, Asia in 1997 and Russia in 1998. The unfolding of the current major crisis will surely offer more evidence, urging a fresh reflection on comparative growth dynamics

Previous issue date: 2015Instituto Nacional de Ciência e Tecnologia Antártico de Pesquisas Ambientais (INCT-APA)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro (FAPERJ)Physiological studies suggest that Antarctic marine organisms are adversely affected by rising global temperatures and ocean acidification and have poor prospects for survival. However, according to ecological studies, their vulnerability might be less severe than initially thought. Thus, a realistic forecast of species survival and Antarctic biodiversity should be based on studies from a variety of species under consideration of ecological factors. The limpet Nacella concinna is often found in the rocky intertidal and sublittoral zones of the Antarctic Peninsula and adjacent subantarctic islands. This review summarizes most of the available information on the biology of this limpet, one of the most conspicuous invertebrates of the intertidal zone. There is some evidence that adult N. concinna are physiologically flexible and can acclimate to 3 A degrees C. However, the requirements of the larval stage are poorly known, thus precluding realistic predictions of how elevated temperatures will affect N. concinna populations. Data on physiological performance (righting ability, tenacity and radula rasping rate) under different temperatures could provide a useful baseline for further field investigations on the effects of warming. The species could be used as model organism for investigating the biological effects of ongoing global warming on slow-growing Antarctic ectotherms. Nacella concinna might also be a better biomonitor for polycyclic aromatic hydrocarbons than other Antarctic mollusks.[Suda, Cecilia N.

Geometrical investigation of cooling channels with two alternated isothermal blocks under forced convective turbulent flow
No full textThe present work performs a numerical analysis of the geometrical investigation of a two-dimensional channel with two alternated isothermal rectangular blocks subjected to turbulent forced convective flows. Constructal Design associated with Exhaustive Search is used to investigate the influence of the geometry of the isothermal blocks over the performance of the cooling convective flows in a multi-objective viewpoint, i.e., considering the pressure drop and heat transfer rate. The time-averaged equations of continuity, momentum, and energy conservation are solved with the finite volume method. The k–ω shear stress transport model is used for the closure of turbulence. The effect of the two proposed degrees of freedom, the height/length ratio of the two blocks (H1/ L1 and H2/ L2) , is analyzed in relation to the proposed objectives. Regarding the thermal purpose, the geometry with the highest insertion into the channel led to the best performance, while the opposite configuration led to the best fluid dynamic performance. This behavior was similar to that previously found in the literature for forced convective laminar flows. For a multi-objective perspective, the use of technique for order preference by similarity to ideal solution indicated that asymmetric blocks led to the best multi-objective performance when both performance indicators had the same weight
Genotipagem do SNP g. 10329T>C no gene estearoil-coa dessaturase (SCD1) relacionado a composição de ácidos graxos.
No full textOs lipídios presentes na carne bovina possuem relação direta com a qualidade de carne, sendo responsáveis por conferir sabor e aroma. Além disso, a maior quantidade de ácidos graxos insaturados está ligada positivamente a saúde humana, reduzindo a incidência de doenças cardiovasculares, por exemplo. O gene SCD1 está localizado no cromossomo 26 de bovinos. O SNP g.10329T>C localizado no quinto éxon do gene, na posição 878pb da Open Read Frame, foi relacionado com aumento de ácidos graxos monoinsaturados e redução do ponto de fusão do tecido adiposo
Polymorphisms in the prion protein gene of cattle breeds from Brazil.
No full textOne of the alterations that occur in the PRNP gene in bovines is the insertion/deletion (indel) of base sequences in specific regions, such as indels of 12-base pairs (bp) in intron 1 and of 23- bp in the promoter region. The deletion allele of 23 bp is associated with susceptibility to bovine spongiform encephalopathy (BSE) as well as the presence of the deletion allele of 12 bp. In the present study, the variability of nucleotides in the promoter region and intron 1 of the PRNP gene was genotyped for the Angus, Canchim, Nellore and Simmental bovine breeds to identify the genotype profiles of resistance and/or susceptibility to BSE in each animal. Genomic DNA was extracted for amplification of the target regions of the PRNP gene using polymerase chain reaction (PCR) and specific primers. The PCR products were submitted to electrophoresis in agarose gel 3% and sequencing for genotyping. With the exception of the Angus breed, most breeds exhibited a higher frequency of deletion alleles for 12 bp and 23 bp in comparison to their respective insertion alleles for both regions. These results represent an important contribution to understanding the formation process of the Brazilian herd in relation to bovine PRNP gene polymorphisms
