The present study aims to present and analyze the ruling of the Brazilian Supreme Court in ADPF 130 (Concentrated constitutional review action, Fundamental Precept Infringement, Argüição de Descumprimento de Preceito Fundamental), proposed by Partido Democrático Trabalhista (PDT), which contests the compatibility of statute 5.250/67 with the Federal Constitution of 1988. This work considers that the judicial ruling is different than the approach taken by the Legislative and Executive powers, arguing that there is, in the Judiciary, a peculiar way for ruling, surrounded by mysteries, rites, secrets, pomp and circunstances unintelligible to layman. To reach the proposed goal, Justice Carlos Brito´s report and opinion on ADPF 130 are analyzed. The choice of giving special attention to this opinion, which favors the declaration of unconstitutionality of the 5.250/67 statute, is justified in that it represents agreement with the allegation of disrespect to the constitutional text, as suggested by the Partido Democrático Trabalhista. The arguments put forth by the presiding Justice on his ruling will also be the object of consideration, as well as some possible consequences of the ruling.

In this paper we present two studies, the first one completed and the second one in development, which are based in teaching approaches that propose the qualitative study of mathematical models as a strategy for the teaching and learning of mathematical concepts. These teaching approaches focus on subjects from Higher Education such as Introduction to Ordinary Differential Equations and Topics of Differential and Integral Calculus. We denominate this common aspect of the teaching approaches as Model Analysis and in a preliminary level we relate it with Mathematical Modeling. Furthermore, we discuss some questions related with the choice of the theme and the role of Digital Technologies when Model Analysis is applied.

In this paper we analyzed and compared two Albert Einstein’s biographies. The first one was “Albert Einstein and his inflatable universe”, written by Mike Goldsmith. The second biography was “Einstein – his life and universe”, written by Walter Isaacson. The intention of this comparison was to identify convergent and divergent points between two books, beyond verifying the possible neglected important points of Einstein’s life suppressed by Goldsmith to facilitate the comprehension of the text. Such details are those that we consider important to Albert Einstein’s intellectual development, and may have significantly contributed to the development of his theories. For this, our analysis was grounded in Douglas Allchin’s perspective, whose work presents aspects in the rhetoric of the text that contribute to the Science and scientist mystification.

The real role of renal transplantation in hepatic fi brosis progression caused by hepatitis C virus is still unpredictable. Histological evaluation of the liver is the best form to estimate fi brosis evolution, although semiquantitative analysis carries important limitations. Objective: To apply a morphometric quantitative assay on hepatic fi brosis progression in renal recipients with hepatits C. Methods: Thirty patients were initially evaluated, but only seven were included. They underwent the fi rst biopsy near the transplantation date and the second biopsy at least 4 years later. The immunosuppressant therapy adopted in all cases was azatioprine and micofenolate. Fibrosis progression rate (FPR) was calculated before and after the surgery date in each patient according to Metavir score and morphometric analysis. Results: The FPR calculated by Metavir score showed no statistical difference between pre- and post-transplantation (p=0.9). The FPR calculated by the morphometric analysis was 0.58 ± 0.78 before transplantation and 3.0 ± 3.3 after the surgery, with statistical signi- fi cance between these values (p=0.0026). Conclusion: In the sample assessed, the progression of hepatic fi brosis was documented and quantifi ed only by the morphometric analysis, which is as a promising approach to histological evaluation of these patients.

The morphometric study in watersheds is a key part to managing watersheds, because from the morphometric indices can determine the risks and potential of each watershed and assess environmental impacts on them generated mainly by human activities. This study aimed to characterize the watershed of the river Verissimo, located in the municipality of Verissimo - MG, analyze morphometric indices and propose how best to use the soil to minimize erosion impacts to resources hídricos.Foi used digital charts 1:100,000 scale and AutoCAD software for the quantification of vector data. The watershed has an area of 146.055 km2 , 55.902 km perimeter. According to the morphometric indices is considered 5th order, highly branched, slightly elongated format of little risk to floods occur, its main channel corresponds to 28.541 kilometers and has undulated, with an average slope of 8.59%. Through the results of morphometric indices and roughness coefficient, shows the potential of watershed land use on pastures for livestock, and soil conservation practices and water to minimize the impacts of erosion and contamination of water resources.
