Multivariate Analysis of Extreme Physical, Biological and Chemical Patterns in the Dynamics of Aquatic Ecosystem  [PDF]
Marilia Mitidieri Fernandes de Oliveira, Gilberto Carvalho Pereira, Nelson Francisco Favilla Ebecken, Jorge Luiz Fernandes de Oliveira
Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.68080
Abstract: This study is a part of the research in monitoring systems of environmental impacts in coastal re-gions in order to develop trophic dynamic models to be used in the aquatic systems management. Meteorological influences in the variability of the nutrients, larvae concentration, dissolved oxygen (DO) and chlorophyll a were investigated in a region where upwelling occurs. Extreme seasonal variations of reanalysis, QuikSCAT, and surface stations from the southeast coast of Brazil, as well as, surface seawater data collected in Anjos Bay, Arraial do Cabo city northeast of Rio de Janeiro state, are analyzed. Seasonality and correlations are applied to verify the relationship between them, considering minimum values of sea surface temperature (SST) and sea level variation and maximum values of the other variables. Principal Component Analysis (PCA) and Hierarquical Cluster Analysis (HCA) are applied to verify spatial and temporal variances and to describe more clearly the structure of the local ecosystem. The seasonality of northeasterly extreme wind stress follows the seasonal pattern expected for the study area with peaks during spring. The SST has a well-defined seasonal pattern with maximum peaks from February to July and minimum peaks from September to January. Chlorophyll a presents higher seasonal peak in February, being in accordance with DO; both are related to the maximum primary productivity. Correlations of the physical variables (local and remote) with nutrients and larvae present a relatively similar pattern around 0.5, showing these variables have a reasonable interaction with the meteorological forcing. PCA shows a strong variability in pressure data around 0.9, which may be related to the seasonal variations in South Atlantic subtropical anticyclone (SASA) and consequently to the occurrence of upwelling in the region. HCA shows the twenty-five parameters into two big clusters with predominance of biotic variables in one side and abiotic ones at the other. The degree of refinement of similarities allowed a division into six clusters of samples, giving the most satisfactory results at forming distinct clusters with more accurate regarding physical and biological elements.

Health (Health) , 2015, DOI: 10.4236/health.2015.74049
Abstract: This is a qualitative study that aims to describe the opinion of nursing students on the use of an educational hypermedia on Peripheral Venipuncture. We interviewed 16 nursing students of a private university on second semester of 2014. The interviews allowed the identification of units of meaning and categorization by content analysis and led to four categories: influence of hypermedia on learning, educational technology as support to teaching classroom, contribution of hypermedia for professional practice and access difficulties. Hypermedia showed positive results as most scholars reported that the material helped in learning and generated autonomy and interactivity in the moment of studying. However some reported difficulties in access hypermedia related mainly to the server used. So hypermedia proved to be a valuable tool to use, since it favored the learning and aroused the interest and curiosity of students.

Alternative System of Industrial Paint Applied to Spherical Mount for Liquefied Petroleum Gas  [PDF]
Fernando B. Mainier, Francisco Otavio Pereira da Silva, Gilberto Oliveira da Silva
Journal of Materials Science and Chemical Engineering (MSCE) , 2014, DOI: 10.4236/msce.2014.25002
Abstract:

The present article reports the application of zinc ethyl silicate paint and the use of internal and external paint schemes on carbon steel spheres for the storage of liquefied petroleum gas. The new paint scheme eliminates the steps of blasting in the field and minimizes the collection of waste generated and the environmental impact, reducing the service time onsite and therefore providing a productivity gain and better health and cleanliness at work. The results were obtained through test runs and qualified in bodies-of-proof made with the same characteristics as the sphere, that is, using the same material (carbon steel), thickness, and mechanical formation and subject to the same conditions of design and implementation process. The paint scheme was approved, qualified, and committed to the supplier’s warranty with the paint manufacturer and assembler of the storage spheres for liquefied petroleum gas.

Pereira, Gilberto Carvalho;Coutinho, Ricardo;Ebecken, Nelson Francisco Favila;
Brazilian Journal of Oceanography , 2008, DOI: 10.1590/S1679-87592008000100001
Abstract: the brazilian coastal zone presents a large extension and a variety of environments. nevertheless, little is known about biological diversity and ecosystem dynamics. environmental changes always occur; however, it is important to distinguish natural from anthropic variability. under these scenarios, the aim of this work is to present a data mining methodology able to access the quality and health levels of the environmental conditions through the biological integrity concept. a ten-year time series of physical, chemical and biological parameters from an influenced upwelling area of arraial do cabo-rj were used to generate a classification model based on association rules. the model recognizes seven different classes of water based on biological diversity and a new trophic index (plix). artificial neural networks were evolved and optimized by genetic algorithms to forecast these indices, enabling environmental diagnostic to be made taking into account control mechanisms of topology, stability and complex behavioral properties of food web.
CSA: An efficient algorithm to improve circular DNA multiple alignment
Francisco Fernandes, Luísa Pereira, Ana T Freitas
BMC Bioinformatics , 2009, DOI: 10.1186/1471-2105-10-230
Abstract: In this paper we propose an efficient algorithm that identifies the most interesting region to cut circular genomes in order to improve phylogenetic analysis when using standard multiple sequence alignment algorithms. This algorithm identifies the largest chain of non-repeated longest subsequences common to a set of circular mitochondrial DNA sequences. All the sequences are then rotated and made linear for multiple alignment purposes.To evaluate the effectiveness of this new tool, three different sets of mitochondrial DNA sequences were considered. Other tests considering randomly rotated sequences were also performed. The software package Arlequin was used to evaluate the standard genetic measures of the alignments obtained with and without the use of the CSA algorithm with two well known multiple alignment algorithms, the CLUSTALW and the MAVID tools, and also the visualization tool SinicView.The results show that a circularization and rotation pre-processing step significantly improves the efficiency of public available multiple sequence alignment algorithms when used in the alignment of circular DNA sequences. The resulting alignments lead to more realistic phylogenetic comparisons between species.Genomic sequence alignment tools have been playing an important role in comparative genomics and phylogenetic reconstruction. However, traditional sequence alignment algorithms based on dynamic programming are very inefficient when long genome sequences needed to be aligned. To tackle this problem several heuristic based methods have been proposed. The most popular progressive multiple sequence alignment (MSA) method is ClustalW [1,2], to which access is provided by a number of web portals. Other methods like T-COFFEE [3], DIALIGN [4], MUSCLE [5], MLAGAN [6], MAVID [7], and MAUVE [8] are also widely used. Despite the fact that these tools are heuristic based and sometimes lead to poor biologically plausible alignments, they were also developed to deal only with linear

Gest?o & Regionalidade , 2007,
Abstract: Strategic positioning must be established through differentiation. And it may be configured across experience movements. For its turn, experiences are getting increasingly plentiful in their own right as aproduct offering and in conjunction with products and services as a way to provide additional value to consumers. But the creation of experiences must be the way to create new economic value for thecompany, which performs those experiences. This paper seeks to broad the comprehension of experiences as differentiation of strategy, and use a case study originated from a Brazilian newspaper that started to add experience events into its sections. The result shows how a media company may use this tool in order to differ itself and createvalue. It means that the creation of value and profitable growth through the experience may be the emerging opportunity space for mediacompanies that may transform its entertainment products (programs, newspapers, magazines) in experimental products.
