Cidade e políticas locais compensatórias
Yara Vicentini
Desenvolvimento e Meio Ambiente , 2004,
Abstract: Deficiency in traditional social policies and public investments has consolidated the increasing poverty of Latin American populations, bringing to the debate the universal or selective contexts of urban social policies. If on one hand, general social security systems are in crises all over the world, on the other hand, social assistance programs aimed at the poor are nothing new. What is new is the connection of strategies targeting meta-groups as a political expression of urban management. It is up to the cities, as stages of social struggle, to build a level of socio-cultural integration and the growth of basic quality indicators and income distribution in Latin America. Their contemporary growth and expansion modelis on a different level in comparison to European capital cities which, with their contemporary urban reforms, develop a concept of city as a strategic asset, promoting localized urban interventions that support ways of income concentration in more sophisticated consumption levels or post-industrial services. This paper discusses Curitiba as a paradigmatic example in Brazil, a city that assimilates urban simulations from other cities of the world, without being a city of the world itself.
Teorias da cidade e as reformas urbanas contemporaneas
Yara Vicentini
Desenvolvimento e Meio Ambiente , 2001,
Abstract: The compreension of the new thought tendencies about the city represents the thematic approached. In the period pos sixties it is discussed the fragmentation on society’s utopia based on the central idea of progress and social appropriation of a technology that it generates quality and equality to the produced wealth. The vanguard conception crystallizes, appropriate by the media of a consuming market. The impossibility of universal urban models reprodution,builds the possibility of approaches more deepened on these new contemporary tendencies. The width and the diversity of the new tendencies was constituted in thematic essential of the work, in the ambit about the understanding on the contemporary urbanization. This article is linked to the area of the urban theory intends to revelate formulations, contents and link paradigms of these new tendencies, analysing international and national citis examples.
TISs-ST: a web server to evaluate polymorphic translation initiation sites and their reflections on the secretory targets
Renato Vicentini, Marcelo Menossi
BMC Bioinformatics , 2007, DOI: 10.1186/1471-2105-8-160
Abstract: An efficient web-based tool entitled TISs-ST (Translation Initiation Sites and Secretory Targets) evaluates putative translation initiation sites and indicates the prediction of a signal peptide of the protein encoded from this site. The TISs-ST web server is freely available to both academic and commercial users and can be accessed at http://ipe.cbmeg.unicamp.br/pub/TISs-ST webcite.The program can be used to evaluate alternative translation initiation site consensus with user-specified sequences, based on their composition or on many position weight matrix models. TISs-ST provides analytical and visualization tools for evaluating the periodic frequency, the consensus pattern and the total information content of a sequence data set. A search option allows for the identification of signal peptides from predicted proteins using the PrediSi software.Translation by cytosolic ribosomes generally occurs at the first AUG in the transcript. However, in eukaryotic mRNAs, efficient recognition of an AUG codon as a translation initiation site (TIS) depends on several factors, such as the nucleotide sequence that flanks the site [1-3]. There is evidence that the context surrounding the initiation codon contributes to the control of translational initiation [4]. The sequence context of the first AUG codon, in particular that part located in the untranslated region, may modulate the efficiency with which it is recognized as a translation initiation codon [5]. If the first initiation codon lies in a suitable context, protein synthesis will be started. When the context is less than favorable, most of the protein synthesis will start at the next downstream AUG codon [6]. Moreover, other structural features of the mRNA are considered important for the efficiency of the translation initiation at a specific AUG codon, such as: the proximity of AUG to the 5' end, the secondary structure upstream and downstream from the AUG codon, the leader sequence length and the multiple upstream AUG

Abstract: from "the third bank of the river" - some considerations about transmission in psychoanalysis. having the intransitive dimension of transmission in psychoanalysis at its core, this paper constructs a comparison between the logic of the literary discourse, in particular the short-story "from the third bank of the river", by j. guimar?es rosa, and some crucial questions of the analytic experience, with the purpose of enacting, on the level of both the enunciation and the statement, an experience of transmission.
Pipeline for macro- and microarray analyses
Vicentini, R.;Menossi, M.;
Brazilian Journal of Medical and Biological Research , 2007, DOI: 10.1590/S0100-879X2006005000089
Abstract: the pipeline for macro- and microarray analyses (pmma) is a set of scripts with a web interface developed to analyze dna array data generated by array image quantification software. pmma is designed for use with single- or double-color array data and to work as a pipeline in five classes (data format, normalization, data analysis, clustering, and array maps). it can also be used as a plugin in the bioarray software environment, an open-source database for array analysis, or used in a local version of the web service. all scripts in pmma were developed in the perl programming language and statistical analysis functions were implemented in the r statistical language. consequently, our package is a platform-independent software. our algorithms can correctly select almost 90% of the differentially expressed genes, showing a superior performance compared to other methods of analysis. the pipeline software has been applied to 1536 expressed sequence tags macroarray public data of sugarcane exposed to cold for 3 to 48 h. pmma identified thirty cold-responsive genes previously unidentified in this public dataset. fourteen genes were up-regulated, two had a variable expression and the other fourteen were down-regulated in the treatments. these new findings certainly were a consequence of using a superior statistical analysis approach, since the original study did not take into account the dependence of data variability on the average signal intensity of each gene. the web interface, supplementary information, and the package source code are available, free, to non-commercial users at http://ipe.cbmeg.unicamp.br/pub/pmma.

Insights into the superdiffusive dynamics through collision statistics in periodic Lorentz gas and Sinai billiard
Valery B. Kokshenev,Eduardo Vicentini
Physics , 2004,
Abstract: We report on the stationary dynamics in classical Sinai billiard (SB) corresponding to the unit cell of the periodic Lorentz gas (LG) formed by square lattice of length $L$ and dispersing circles of radius $R$ placed in the center of unit cell. Dynamic correlation effects for classical particles, initially distributed by random way, are considered within the scope of deterministic and stochastic descriptions. A temporal analysis of elastic reflections from the SB square walls and circle obstacles is given for distinct geometries in terms of the wall-collision and the circle-collision distributions. Late-time steady dynamic regimes are explicit in the diffusion exponent $z(R)$, which plays a role of the order-disorder crossover dynamical parameter. The ballistic ($z_{0}=1$) ordered motion in the square lattice (R=0) switches to the superdiffusion regime with $z_{1}=1.5$, which is geometry-independent when $R
Slow relaxation in weakly open vertex-splitting rational polygons
Valery B. Kokshenev,Eduardo Vicentini
Physics , 2002, DOI: 10.1103/PhysRevE.68.016221
Abstract: The problem of splitting effects by vertex angles is discussed for nonintegrable rational polygonal billiards. A statistical analysis of the decay dynamics in weakly open polygons is given through the orbit survival probability. Two distinct channels for the late-time relaxation of type 1/t^delta are established. The primary channel, associated with the universal relaxation of ''regular'' orbits, with delta = 1, is common for both the closed and open, chaotic and nonchaotic billiards. The secondary relaxation channel, with delta > 1, is originated from ''irregular'' orbits and is due to the rationality of vertices.
Morphological Features of the Apical Region in the Principal Cells of Mongrel Dog Epididymis
Schimming,Bruno Cesar; Vicentini,Carlos Alberto;
International Journal of Morphology , 2008, DOI: 10.4067/S0717-95022008000100025
Abstract: the epithelial principal cells are the predominant cell type of the epididymis. these cells have been shown to be both secretory and endocytic cells. the apical region of the cytoplasm of principal cells in the mongrel dog are located close to the cell apex and tubular lumen, and shown microvilli at the luminal border and present a endocytic apparatus, that consists of coated pits and vesicles, endosomes of varying size, multivesicular bodies, and lysosomes. the endosomes, multivesicular bodies and lysosomes contained the electron-dense patches. these results suggest that principal cells of the epididymis in the dog as possess a highly developed endocytic apparatus play a role in endocytosis. these cells function are similarly to the related in other mammals, in performing endocytosis.
