Professores de Street Dance do Estado de São Paulo: formação e saberes

This research of qualitative nature, aimed to analyze the formation and knowledges of the teachers of Street Dance from the State of São Paulo. Reviewing the literarature it was approached the conceptions of culture, "Hip Hop Culture", and Street Dance. Also, some studies referred to the professional formation in dance and Physical Education; acting in dance by the teacher of Physical Education; and professional academic formation and/or experimental. The approaching method was the story of the time at present. The technique: interview semi-structured. According to the analysis of the statements: a) we noticed that no one of the interviewers show academic formation in dance; a small part is graduated in Physical Education, and the majority act as authorized teachers by the CREF and/ or DRT; b) we verified that the teaching of Street Dance is determined by experimental knowledges. The Street Dance shows itself as a process of constitution, and the formation and the knowledges to its teaching did not show systematization.

Assinaturas antropogênicas de elementos maiores e traços em poeira urbana na cidade do Natal-RN

Although there are many studies on urban dust contamination by heavy metals in developed countries, little attention has been paid to this type of study in developing countries, including Brazil. Therefore, a series of investigations were performed to provide signatures of heavy metals in urban dust and assess the potential sources in the city of Natal - RN-Brazil. The fraction of these sediments was studied to pass through a sieve of 63 micrometers. For the study analyzed two groups of samples, one collected in September 2009 at the end of the rainy season (9 samples) and one collected in January 2010 in the dry season (21 samples). So in all, thirty sediment samples were collected from the street. Then, in Fluorescence Spectrometry X-rays were determined major elements SiO2, Na2O, K2O, Al2O3, MgO, P2O5, Fe2O3, MnO, TiO2 and CaO, and trace Rb, Cr, Ni, Cu, Zn, Sr and Pb by an ICPOES was determined Zn, V, Na, K, Ni, Mn, Mg, P, Fe, Cr, Cu, Pb, Ba, Ca and Al from leaching HCl 0.5 mol L-1 . The results of the concentrations of elements show that the greater presence of these occurs in the dry season, except for Si which is higher in the rainy season. Analyses by geoaccumulation Index (IGEO) Enrichment Factor (EF), Contamination Factor (CF), analysis correlation and Hierarchical Cluster, confirm that Zn, Cu and Pb is anthropogenic character. Zinc may be derived from various sources related to motor vehicles or the road signs and street grids. The elements Na, K, Mg and Ca may be related to droplets suspended in air containing cations and anions present in seawater (salty), common in Christmas throughout the year, brought by winds SE-NW. The elements Na, Mg, Ca and K are the most abundant in seawater and were analyzed in this study. This indicates that the source of these additional elements detected by analyzing the contamination factor may be the very sea. Moreover, Ni, Fe, Cr and Ba can be either as a source of anthropogenic geogênica. The source of Ca is different, because it comes in lime and paint (painting guides of buildings and streets) in construction materials, but may also be present in sediments in the fragments of shells or carbonate bioclasts common in the coastal area

First-order formalism for dark energy and dust

This work deals with a first-order formalism for dark energy and dust in standard cosmology, for models described by a real scalar field in the presence of dust in spatially flat space. The field dynamics may be standard or tachyonic, and we show how the equations of motion can be solved by first-order differential equations. We investigate a model to illustrate how the dustlike matter may affect the cosmic evolution using this framework.

A study on automatic methods based on mathematical morphology for Martian dust devil tracks detection

This paper presents three methods for automatic detection of dust devils tracks in images of Mars. The methods are mainly based on Mathematical Morphology and results of their performance are analyzed and compared. A dataset of 21 images from the surface of Mars representative of the diversity of those track features were considered for developing, testing and evaluating our methods, confronting their outputs with ground truth images made manually. Methods 1 and 3, based on closing top-hat and path closing top-hat, respectively, showed similar mean accuracies around 90% but the time of processing was much greater for method 1 than for method 3. Method 2, based on radial closing, was the fastest but showed worse mean accuracy. Thus, this was the tiebreak factor. © 2011 Springer-Verlag.

Automated determination of the orientation of dust devil tracks in mars orbiter images

The paper presents and evaluates three methods for automatically estimating the main orientation of Martian dust devil tracks in MOC and HiRISE images. Inferring such information about dust devils from their tracks is important to better understand the near surface wind. The methods considered were based on gradient direction, directional openings and morphological granulometry. The accuracy of the methods was asserted by comparing the results to a set of directions estimated visually and assumed to be the ground truth. The higher accuracy was reached using directional openings. Besides, the directions inferred by this method were compared to those predicted by the GCM and the results agreed. © 2013 COSPAR.

A dialética da malandragem revisitada em O Xangô de Baker Street

Using the concept of influence, well explored by Sandra Nitrini (2000), the purpose of this study is to verify the characterization of the main characters of O Xangô de Baker Street (1995) and Macunaíma, o herói sem nenhum caráter (1928) – Sherlock Holmes and Macunaíma – as rogues in their novels, heirs to the Spanish picaresque, a genre that has taken on new meaning in Brazilian literature, as pointed out since the 1960s by Antonio Candido in his famous essay “Dialética da malandragem” (2010). With these theories, we analyze the composition of the tricksters, whose starting point is the question facing the country, the Brazilian. Although the distances in time and style of separating the protagonists created by Jô Soares and Mário de Andrade, we have noticed the interesting procedure of re-creation of the renowned English detective created by Arthur Conan Doyle and the reinterpretation of aspects of Brazilian folklore a convergence of interests with regard to representation of the national character.

Extensive computation of albedo contrast between martian dust devil tracks and their neighboring regions

We have developed a method to compute the albedo contrast between dust devil tracks and their surrounding regions on Mars. It is mainly based on Mathematical Morphology operators and uses all the points of the edges of the tracks to compute the values of the albedo contrast. It permits the extraction of more accurate and complete information, when compared to traditional point sampling, not only providing better statistics but also permitting the analysis of local variations along the entirety of the tracks. This measure of contrast, based on relative quantities, is much more adequate to establish comparisons at regional scales and in multi-temporal basis using imagery acquired in rather different environmental and operational conditions. Also, the substantial increase in the details extracted may permit quantifying differential depositions of dust by computing local temporal fading of the tracks with consequences on a better estimation of the thickness of the top most layer of dust and the minimum value needed to create dust devils tracks. The developed tool is tested on 110 HiRISE images depicting regions in the Aeolis, Argyre, Eridania, Noachis and Hellas quadrangles. As a complementary evaluation, we also performed a temporal analysis of the albedo in a region of Russell crater, where high seasonal dust devil activity was already observed before, comprising the years 2007-2012. The mean albedo of the Russell crater is in this case indicative of dust devil tracks presence and, therefore, can be used to quantify dust devil activity. (C) 2014 Elsevier Inc.

O fluxo da consciência em Ask the dust, de John Fante

The purpose of this research is to present de narrative techniques of the Stream of Consciousness in the novel Ask the dust, by American writer John Fante, as well as analyzing the technique applying it to the character/narrator Arturo Bandini. Among others, the emphasys was given to the interior monologue technique, for its large and intense use throughout the analyzed novel. This research was based specially on O Fluxo da consciência (1976), by Robert Humphrey, and Foco narrativo e fluxo da consciência (2012), de Alfredo Leme Coelho de Carvalho, both important researchers in the studied theme. This research, therefore, intends to demonstrate the geniality of the still little-known John Fante and point out the peculiarities of the so-called 'psychological fiction', that in the early 20th century united literature and psychology studies, becoming very popular in modern literature, with exponents like Virginia Woolf and James Joyce
