Infraestrutura de data center e suas tendências com foco em eficiência energética

With the Big Data development and the growth of cloud computing and Internet of Things, data centers have been multiplying in Brazil and the rest of the world. Designing and running this sites in an efficient way has become a necessary challenge and to do so, it's essential a better understanding of its infrastructure. Thus, this paper presents a bibliography study using technical concepts in order to understand the specific needs related to this environment and the best forms address them. It discusses the data center infrastructure main systems, methods to improve their energy efficiency and their future trends

Performance of an operating high energy physics data grid: DOSAR-Grid

The DO experiment at Fermilab's Tevatron will record several petabytes of data over the next five years in pursuing the goals of understanding nature and searching for the origin of mass. Computing resources required to analyze these data far exceed capabilities of any one institution. Moreover, the widely scattered geographical distribution of DO collaborators poses further serious difficulties for optimal use of human and computing resources. These difficulties will exacerbate in future high energy physics experiments, like the LHC. The computing grid has long been recognized as a solution to these problems. This technology is being made a more immediate reality to end users in DO by developing a grid in the DO Southern Analysis Region (DOSAR), DOSAR-Grid, using a available resources within it and a home-grown local task manager, McFarm. We will present the architecture in which the DOSAR-Grid is implemented, the use of technology and the functionality of the grid, and the experience from operating the grid in simulation, reprocessing and data analyses for a currently running HEP experiment.

Lesões desportivas na natação

O estudo objetivou analisar a ocorrência de lesões em nadadores, associando-as a fatores de risco específicos da modalidade e do atleta. Fizeram parte desse estudo 215 atletas, de ambos os sexos, participantes dos principais campeonatos promovidos pela Federação Aquática Paulista. Os dados foram obtidos por meio de Inquérito de Morbidade Referida, constituído por perguntas relacionadas ao atleta, modalidade e referentes ao tipo, mecanismo e local da lesão. A análise entre variáveis antropométricas e presença de lesão foi realizada pelo teste t de Student ou pelo teste não paramétrico de Mann Whitney. Para relação entre as especificidades e o tipo, mecanismo e local da lesão, utilizou-se o teste de Goodman. Resultados significantes foram obtidos entre os atletas lesionados com mais idade e anos de treinamento. Segundo o mecanismo da lesão, o volume dos treinos é a principal causa de ocorrências de lesões e as tendinopatias são as lesões mais comuns. O ombro é o local mais acometido pelas diferentes especialidades, com exceção dos nadadores de peito que referiram a virilha. Conclui-se a partir dos achados que a exposição dos nadadores a prática esportiva associada ao volume de treinamento estão relacionadas com as frequentes lesões nestes atletas.

Microbial culture collections as pillars for promoting fungal diversity, conservation and exploitation

Fungi are a diverse group of organisms with an overall global number of 1.5 M up to 3.3 M species on Earth. Besides their ecological roles as decomposers, fungi are important in several aspects of applied research. Here, we review how culture collections may promote the knowledge on diversity, conservation and biotechnological exploitation of fungi. The impact of fungi diversity on biotechnological studies is discussed. We point out the major roles of microbial repositories, including fungal preservation, prospecting, identification, authentication and supply. A survey on the World Data Center for Microorganisms (WDCM) powered by the World Federation for Culture Collections and on the Genetic Heritage Management Council (CGEN) database revealed that 46 Brazilian culture collections registered in these databases are dedicate to preserving fungi. Most of these culture collections are located in the Southeast of Brazil. This scenario also demonstrates that Brazil has many collections focused on fungal strains, but the lack of up-to-date information in WDCM as well as of a solid national platform for culture collections registration do not allow accurate assessment of fungal preservation. © 2013 Elsevier Inc.

A formação continuada de professores: entre o real e o 'ideal'

The objective this study was to highlight the prospects of a group of teachers of Physical Education, highlighting the factors identified as critical to a continuing education "ideal" for a teacher professional development and for the practice pedagogical. Qualitative research, inspired by the method of approaching the history of the present time, in order to register as memory the time when these teachers live. The data source used was oral sources collected by the technique of semistructured interviews and official documents. The data generated were discussed with the production of literature and the highlights are three axes in the reports of teachers: the relationship between theory and practice, the importance of listening to students and the continuity of training activities.
