Tecnologias de Informação e Comunicação (TICs) e literatura, uma aposta notável

The aim of this study was to develop a qualitative research of bibliographic nature, in order to verify how has been the use of new Information and Communication Technologies (ICTs) and literary reading in early childhood education.. It is believed to be necessary for children, since their early childhood, to, be in contact with various literary works of aesthetic value, which will enable them to understand this particular literary language - and the imagery that comes with it - what can instigate appreciate literature and get the reading habit. The use of ICTs by children beyond the use of games and watching stories on computers, tablets and smartphones, for example, for the production of videos and slides or creating stories, enable new experiences of redesigning and construction of knowledge and culture. The idea for this research came from reading the numerous texts that deal with the need to understand the child as an active subject in the construction of culture and society, rather than as receiving reproductive and cultural orders (CRIANÇAS, 2012). In this sense, in addition to the newsletters Equity For Children: Latin America (CRIANÇAS, 2012), the understanding of childhood and child in the works of Walter O. Kohan (2005; 2006) supports this study. This research proposal was also based on authors and documents that point to the need to promote, since the first stages of Basic Education, the literary reading as a means of enjoyment and emancipation (LAJOLO 2001a; Barthes, 2007; FILIPOUSKY, 2009; BRAZIL, 2010; MACHADO, 2011; VASQUES, 2013), and an education connected to the technological advances of the twenty-first century (BRAZIL, 1997, CHAVES, 1998; DEMO, 2008)

Ultrassonografia transtorácica extracardíaca: revisão de Literatura

Radiography is usually the primary method of diagnosis to be used in the initial evaluation of the chest. In view of recent technological advances in ultrasound machines, noncardiac transthoracic ultrasound has become an important method of diagnosis for diseases of the lung, pleura, mediastinum and chest wall. Despite limitations due to the difficulty of efficient sound propagation in air, this exam allows fast decisions and makes sample collection safer and more effective. Knowledge of the sonographic chest anatomy is however restricted because of the artifact caused by the presence of air in lungs. When absent, it facilitates the detection of thoracic alterations. The aim of this review is to present the main abnormalities that are likely to be detected by ultrasonography.

Perda de matéria seca em grãos de milho submetidos a sistemas de secagem natural e artificial.

The permanence of the corn grain in the field, after physiological maturity, is an important cause of crop losses, both in quantitative and qualitative aspect. By ceasing the supply of assimilated substances to grains, due to physiological maturity, the synthesis reactions are overcome by breathing, responsible for the maintenance of the living tissues of the grains, which occur at the expense of reserves accumulated during grain formation. In addition, there are losses from fungus and insects attack due to adverse weather conditions. Technological advances in recent decades, the develop of grain dryers with different capacities and efficiencies, has led to the early withdrawal of the product from the field, still damp, reducing spoilage. Moreover, the use of artificial drying systems can represent a significant cost to the producer. Thus, the present work aimed to study the effect of natural and artificial methods of drying on maize dry matter losses, for Botucatu, city of Sao Paulo state, Brazil. The cornfield production was conducted at the Experimental Farm “Lageado” and the experimental treatments were conducted in the Laboratory of Agricultural Products Processing, in the Department of Rural Engineering, where the drying systems were tested. The treatments were: shade (control), artificial with heated air, artificial unheated air and, drying attached to the plant. The following analyzes for quality monitoring were performed: weight test, thousand-grain weight test and, grain dry weight. The results showed significant loss in quality of drying beans attached to the plant, by assessing the dry matter loss and by the variation of the grain weight. The weight test showed that the worst performance was the artificial with heated air treatment. We used mathematical modeling techniques to describe the dry matter loss and adjusted the mathematical model to the experimental data analyzed. From the experimental data obtained during drying the grain attached to the plant, it was still possible to fit a regression model that estimates the loss of grain dry matter under the climate from Botucatu during the 2011/2012 harvest period.

Aplicação de carbono vítreo monolítico para produção de eletrodos a partir da resina furfurílica com diferentes variações de pH

Nowadays, we live in a time of rapid research for technological advances, in a way that this pursuit of new technologies is deeply connected to the diversity of new materials that have been developed by mankind. It deals with issues such as materials with enhanced properties which offer better quality, less cost and high performance, while they are accessible both in their production and moment of operation. In this context, it was required to develop electrodes that were easy to prepare as well as which present high electric conductivity and good mechanic proprieties by using carbonaceous material as basis. For this reason, the best parameters of the furfuryl resin cures were established with different pH variations through viscosimetric measurements and differential scanning calorimetry. By scanning electron microscopy (SEM) was possible to identify an increased porosity in the samples with pH 7 and pH 8, as compared to samples with lower pH content. After carbonization of the material, the characterization of monolithic glassy carbon was held by means of FT-IR techniques, Raman spectroscopy, X-ray diffraction and cyclic voltammetry. The spectra showed that the change in pH does not have significant influence on the crystallographic ordering of the material and its structural characteristics. As for the electrochemical character, the CVM electrodes showed excellent response, with good reversibility and wide potential window. Some voltammetric curve deviations were only observed for the sample with pH 4, which may be related to processing parameters adopted
