Scientia Iuris , 2011,
Abstract: Consolidados os direitos humanos no plano internacional, e estruturando-se um sistema para sua prote o, capitaneado pela ONU, surge um novo paradigma para a ordenamentos jurídicos internos. O artigo analisa sua incorpora o ao ordenamento jurídico brasileiro como Direitos Fundamentais, ocupando-se em especial dos direitos da seguridade social. Classificados como direitos prestacionais, o que implica necessariamente em uma atua o positiva do Estado no atendimento a demandas nas áreas de saúde, assistência social e previdência, examina-se a forma pela qual pode-se garantir sua efetividade diante da escassez de recursos financeiros, com a possibilidade de controle judicial sobre a es ou omiss es da Administra o Pública.
Strategies for Achieving Sustainable Logging Rate in the Brazilian Amazon Forest  [PDF]
Evaldo Mu?oz Braz, Patricia Povoa de Mattos, Mariana Ferraz Oliveira, Renato Olivir Basso
Open Journal of Forestry (OJF) , 2014, DOI: 10.4236/ojf.2014.42015

Data of increment of the remnant trees after logging, ingrowth and mortality was obtained by assessment before logging and after 6 years, two sites of 50 ha, in Amazon forest. Logging scenarios were simulated to identify the logging rate potential for each studying site, by diameter class projection method. The cycle of 35 years and the logging rate of 30 m3.ha-1 exceed the time required for recovery in the primary forest, in the studied site. The simulation showed that in the studying area, a well-planned logging, with minimum logging damage would be possible to implement an initial cycle of 25 years to the forest to recover 30 m3.ha-1, if 50% of the timber stock were reserved. The forest increment, beyond important factors such as the increase of individual species, is quite dependent on the remnant trees.



Gradient descent learning in and out of equilibrium
Nestor Caticha,Evaldo Araujo de Oliveira
Physics , 2000, DOI: 10.1103/PhysRevE.63.061905
Abstract: Relations between the off thermal equilibrium dynamical process of on-line learning and the thermally equilibrated off-line learning are studied for potential gradient descent learning. The approach of Opper to study on-line Bayesian algorithms is extended to potential based or maximum likelihood learning. We look at the on-line learning algorithm that best approximates the off-line algorithm in the sense of least Kullback-Leibler information loss. It works by updating the weights along the gradient of an effective potential different from the parent off-line potential. The interpretation of this off equilibrium dynamics holds some similarities to the cavity approach of Griniasty. We are able to analyze networks with non-smooth transfer functions and transfer the smoothness requirement to the potential.

Abstract: the first choice of treatment for american cutaneous leishmaniasis is the pentavalent antimonial drug. although it has been shown that this treatment is mostly effective and indicated, some disadvantages should be taken into account such as side effects, long term treatment inconveniences and counter-indication for patients suffering from cardiopathy, nephropathy; yet, aging, pregnancy and other conditions. with the advent of the vaccine anti-american cutaneous leishmaniasis as a prophylactic measure, studies on therapy using the vaccine associated or not with other drugs have been performed by many investigators and it is currently among the alternative treatments and prevention measures for american cutaneous leishmaniasis. in conclusion, the association between antimony and vaccine (immunochemotherapy) showed the same cure rate when compared with the standard treatment (100%) and it was also able to reduce the salt volume in 17.9% and treatment length from 87 to 62 days, decreasing side effects.
Short-Time Derivatization Method for Analysis of Abamectin in Water Using High-Performance Liquid Chromatography Coupled to Fluorescence Detector  [PDF]
Daniela Cordeiro, Luciana Teresa Dias Cappelini, Raphael Teixeira Verbinnen, Gustavo Henrique Louren?o Vicente, Andréa Novelli, Evaldo Luiz Gaeta Espíndola, Eny Maria Vieira
American Journal of Analytical Chemistry (AJAC) , 2014, DOI: 10.4236/ajac.2014.516117
Abstract: A method using a short-time derivatization step for the assessment of abamectin in water is presented. Abamectin derivative stable up to 7 days was obtained. Some regions where orange crops are present have received abamectin doses, aiming to increase the productivity and to combat pests and weeds, even when its residues reach the aquatic environment and interfere on water quality. Water samples from Jacaré-Pepira River (Brotas City, Brazil) nearby orange crops around urban zone, were evaluated for the presence of abamectin. The analytical method was validated resulting recovery around 108%, precision of 12%, accuracy of 104%, correlation coefficient of 0.9945, and detection and quantification limits of 0.1 μg·L﹣1 and 0.2 μg·L﹣1, respectively. Stable abamectin derivative was reached after 60 min of derivatization at room temperature (25°C). No abamectin residues were found into samples.
Inference of gene regulatory networks from time series by Tsallis entropy
Fabrício Lopes, Evaldo A de Oliveira, Roberto M Cesar
BMC Systems Biology , 2011, DOI: 10.1186/1752-0509-5-61
Abstract: In this paper we introduce the use of generalized entropy proposed by Tsallis, for the inference of GRNs from time series expression profiles. The inference process is based on a feature selection approach and the conditional entropy is applied as criterion function. In order to assess the proposed methodology, the algorithm is applied to recover the network topology from temporal expressions generated by an artificial gene network (AGN) model as well as from the DREAM challenge. The adopted AGN is based on theoretical models of complex networks and its gene transference function is obtained from random drawing on the set of possible Boolean functions, thus creating its dynamics. On the other hand, DREAM time series data presents variation of network size and its topologies are based on real networks. The dynamics are generated by continuous differential equations with noise and perturbation. By adopting both data sources, it is possible to estimate the average quality of the inference with respect to different network topologies, transfer functions and network sizes.A remarkable improvement of accuracy was observed in the experimental results by reducing the number of false connections in the inferred topology by the non-Shannon entropy. The obtained best free parameter of the Tsallis entropy was on average in the range 2.5 ≤ q ≤ 3.5 (hence, subextensive entropy), which opens new perspectives for GRNs inference methods based on information theory and for investigation of the nonextensivity of such networks. The inference algorithm and criterion function proposed here were implemented and included in the DimReduction software, which is freely available at http://sourceforge.net/projects/dimreduction webcite and http://code.google.com/p/dimreduction/ webcite.In general, living organisms can be viewed as net-works of molecules connected by chemical reactions. More specifically, the cell control involves the activity of several related genes through gene networks, with

Open Journal of Metal (OJMetal) , 2012, DOI: 10.4236/ojmetal.2012.21001
Abstract: Diamond-like Carbon (DLC) coatings have attracted significant attention due to their low friction coefficient, high degree of hardness, chemical inertness, and high wear resistance as well as and their many possible uses in metallurgical, aeronautical, and biomedical applications. However, DLC has low adhesion strength to metallic substrates. Carbonitriding was performed before DLC deposition to improve this adherence. Different concentration of nitrogen in the gas mixture was used during the carbonitriding of Ti6Al4V alloy. DLC films were subsequently grown from methane using plasma enhanced chemical vapor deposition. The samples were characterized with Raman scattering spectroscopy, nanoindentation, and tribological tests. Films from 80.0% N2 had the best friction coefficient (0.07) and a critical load of ~22 N. In the scratching test, these films had adhesive failure and they completely detached from the substrate only in the end of the tests. SEM images show carbonitring promoted a significant increase in the surface defects (homogeneously distributed) but without the presence of microcracks. EDX analysis indicated that nitrogen element was diffused throughout the thickness of the samples. Hydrogen and carbon atoms from carbonitriding formed a diffusion-barrier layer that can be used as the first step for DLC deposition. This carbonitriding can also provide a carbide layer, which serves as the precursor for the nucleation and growth of DLC films.

Fractal : Revista de Psicologia , 2011, DOI: 10.1590/S1984-02922011000200004
Abstract: the aim of this study is to give visibility to the construction of a conceptual cartography, in which it is possible to analyse the movement of the supervised training program as a teachers' formation politics, as well as to make evident the contributions of the intervention-research and cartography for the teachers' formation area. for this purpose, a conceptual and methodological construction are presented in the discussion by means of the cartography and the intervention-research; the analysis of the log books, both from the teacher as the students, and the notes created during the school semester. within this context of analysis, the inventive formation is discussed by means of existence aesthetics constitution and the political problem of supervised training during teacher's formation, taking this problem under a micropolitical dimension. it can be concluded that these are tools for facing the complexity of the school, taking it as the constitution of a territory in movement, that struggles to be a factory and user of a living knowledge.
