Estudos Econ?micos (S?o Paulo) , 2010, DOI: 10.1590/S0101-41612010000300003
Abstract: this article examines the brazilian entrepreneurs' attitudes towards the economic policy of janio quadros' government. the analysis concentrates on the s?o paulo's associations of industrial, commercial and agricultural employers. it is argued that these groups played an important role in shaping economic policies, in particular those related to the exchange rate, credit and antitrust legislation. the evidences gathered in this article bring new light on the management of economic policy during a critical period of brazilian history.
Varrendo a democracia: considera??es sobre as rela??es políticas entre Janio Quadros e o Congresso Nacional
Loureiro, Felipe Pereira;
Revista Brasileira de História , 2009, DOI: 10.1590/S0102-01882009000100008
Abstract: this article examines the relation between president janio quadros and the national congress during the early 1960’s. based on the analysis of the discourse of these figures, it proposes that quadros maneuvered to diminish the legitimacy of the congress in the public opinion, thus disrespecting its constitutional competencies. consequently, it shows that not only did the congress structure political mechanisms in an attempt to recover its credibility with society, but also that this dispute and its results had important effects on president jo?o goulart’s administration and even on the 1964 military coup.
Reliability Estimators for the Components of Series and Parallel Systems: The Weibull Model  [PDF]
Felipe L. Bhering, Carlos A. de B. Pereira, Adriano Polpo
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.511157

This paper presents a hierarchical Bayesian approach to the estimation of components’ reliability (survival) using a Weibull model for each of them. The proposed method can be used to estimation with general survival censored data, because the estimation of a component’s reliability in a series (parallel) system is equivalent to the estimation of its survival function with right- (left-) censored data. Besides the Weibull parametric model for reliability data, independent gamma distributions are considered at the first hierarchical level for the Weibull parameters and independent uniform distributions over the real line as priors for the parameters of the gammas. In order to evaluate the model, an example and a simulation study are discussed.

Treatment of Materials Contaminated with Polychlorinated Biphenyls (Pcbs): Comparison of Traditional Method and Supercritical Fluid Extraction  [PDF]
Dannielle Jannaine Silva, Felipe V. Pietri, José Ermirio F. Moraes, Reinaldo Camino Bazito, Camila Gambini Pereira
American Journal of Analytical Chemistry (AJAC) , 2012, DOI: 10.4236/ajac.2012.312A118

The objective of this study was to develop an experimental methodology for the extraction of polychlorinated biphenyls (PCBs) from contaminated soil and wood material using the Soxhlet extraction method and supercritical fluid technology. The sample PCB contents were quantified using Gas Chromatography-Mass Spectrometry (GC/MS). Conventional extractions of PCBs from soil samples showed higher extraction yields for samples with the highest initial PCB levels and longest extraction times. Specific PCBs yielded 74.0% - 78.3% removal using ethanol as the solvent. 91.0% - 94.3% removal of the total PCB content was achieved using hexane as the solvent. Supercritical fluid extraction of soil samples resulted in 50.0% - 70.5% removal for specific PCBs and 57.3% removal of the total PCB content. For wood, the use of Soxhlet extraction resulted in 87.0% - 94.0% removal for specific PCBs and 95.0% - 96.3% removal of the total PCB content. Supercritical fluid extraction of wood samples resulted in 91.1% - 95.0% removal of specific PCBs and 95.1 % of the total PCB content.

Abstract: purpose: to develop a simple and quick-to-apply procedure for pitch-matching scanning that contains vocal imitation tasks of musical sounds of different tones and the temporal ordination of three different tones; to verify its applicability, by comparing the performance of musicians and non-musicians. methods: participants were 32 adults of both genders without vocal, hearing and/or auditory processing complaints. they were equally divided into two groups: musicians group - mg and non-musicians group - nmg. all participants underwent the pitch-matching scanning that included musical stimuli compatible with men and women singing vocal range gathered into two types of tasks: isolate tones and three-tone sequences. participants were instructed to listen to them and to reproduce them vocally. voice samples were recorded, analyzed acoustically, and right and wrong matches for the two tasks were characterized. the variables regarding the comparison between groups and types of tasks were statistically analyzed. results: a difference was found between groups, and the mg presented greater number of right matches in both tasks. conclusion: the pitch-matching scanning was developed and was sensitive to evaluate and compare the performance between groups. thus, it can be used as a tool for pitch-matching tracking. musicians presented better performance than non-musicians in the pitch-matching scanning.

A Dialogue System for Coherent Reasoning with Inconsistent Knowledge Bases  [PDF]
Silvio do Lago Pereira, Luiz Felipe Zarco dos Santos, Lucio Nunes de Lira
Journal of Computer and Communications (JCC) , 2015, DOI: 10.4236/jcc.2015.38002
Abstract: Traditionally, the AI community assumes that a knowledge base must be consistent. Despite that, there are many applications where, due to the existence of rules with exceptions, inconsistent knowledge must be considered. One way of restoring consistency is to withdraw conflicting rules; however, this will destroy part of the knowledge. Indeed, a better alternative would be to give precedence to exceptions. This paper proposes a dialogue system for coherent reasoning with inconsistent knowledge, which resolves conflicts by using precedence relations of three kinds: explicit precedence relation, which is synthesized from precedence rules; implicit precedence relation, which is synthesized from defeasible rules; mixed precedence relation, which is synthesized by combining explicit and implicit precedence relations.
Divergence of the Thermal Conductivity in Uniaxially Strained Graphene
Luiz Felipe C. Pereira,Davide Donadio
Physics , 2013, DOI: 10.1103/PhysRevB.87.125424
Abstract: We investigate the effect of strain and isotopic disorder on thermal transport in suspended graphene by equilibrium molecular dynamics simulations. We show that the thermal conductivity of unstrained graphene, calculated from the fluctuations of the heat current at equilibrium is finite and converges with size at finite temperature. In contrast, the thermal conductivity of strained graphene diverges logarithmically with the size of the models, when strain exceeds a relatively large threshold value of 2%. An analysis of phonon populations and lifetimes explains the divergence of the thermal conductivity as a consequence of changes in the occupation of low-frequency out-of-plane phonons and an increase in their lifetimes due to strain.
Evaluation of Environmental and Ecological Effects Due to the Accident in an Oil Pipe from Petrobras in Guanabara Bay, RJ, Brazil  [PDF]

Open Journal of Marine Science (OJMS) , 2014, DOI: 10.4236/ojms.2014.44027
Abstract: We aim to evaluate the quality of the Guanabara Bay sediments and the ecological changes due to the PETROBRAS crude oil leak in January 2000. Twenty-six sediment samples collected in July 2000 and in February 2001 were analyzed for pH, dissolved oxygen, and foraminiferal composition. In the northwest and central parts of the bay, low oxygen dissolved values are related to waste discharges with the dominance of Buliminella elegantissima. In winter, near Iguaçu River, the pH of the sediment is low, therefore highly acidic. The acidity is responsible for the foraminiferal low diversity limiting the occurrence of species with fragile tests. On the other hand, thicker tests of Elphidium spp. disappeared last, therefore increasing its relative dominance in winter. In summer, this is a barren zone. The explanation lies in the continuous dissolution of tests that culminated with the total disappearance of these microorganisms one year after the accident.
