The work proposed by Cleverton Hentz (2010) presented an approach to define tests from the formal description of a program s input. Since some programs, such as compilers, may have their inputs formalized through grammars, it is common to use context-free grammars to specify the set of its valid entries. In the original work the author developed a tool that automatically generates tests for compilers. In the present work we identify types of problems in various areas where grammars are used to describe them , for example, to specify software configurations, which are potential situations to use LGen. In addition, we conducted case studies with grammars of different domains and from these studies it was possible to evaluate the behavior and performance of LGen during the generation of sentences, evaluating aspects such as execution time, number of generated sentences and satisfaction of coverage criteria available in LGen

The study area is located in the northern coast of Rio Grande do Norte State comprising the mouth of Açu-Piranhas river including the cities of Porto do Mangue e Areia Branca. The local geological setting comprises Cretaceous, Tertiary and Quaternary geological units of the Potiguar Basin. One is about a region of high morphologic instability due to action of the rigorous dynamic coastal processes, beyond the intense human activities mainly for the performance of the petroliferous industry, salt farms and tanks of shrimp industry.For the accomplishment of this work Landsat 5 TM and Landsat 7 ETM + from four distinct dates were used as cartographic base, in which one applied techniques of digital processing to elaborate thematic maps of the existing natural resources to support the geologic and geomorphologic characterization and the soil and landuse maps. The strategy applied was the interpretation of multitemporal images from aerial and orbital remote sensors alIied to the terrain truth recognition, integrated through a Geographic Information System. These activities had alIowed the production of Sensitivity Maps of the Coast to Oil Spilling for the area, on the basis of the Coastal Sensibility Index. Taking into account the seasons were created maps to distinct datas: July 2003 represents the winter months that presented a sensibility lower when compared with the month of December 2003. For the summer months greater sensitivity is due to the hydrodynamic data that suggest a lesser capacity of natural cleanness of the oil and its derivatives in spilling case.These outcomes are an important and useful database to support an assessment to a risk situation and to taking decision in the face of an environmental disaster with oil spilling in coastal area, alIowing a complete visualization of the area and identifying all portions in the area with thei environmental units and respective Coastal Sensibility Index.

The northern portion of the Rio Grande do Norte State is characterized by intense coastal dynamics affecting areas with ecosystems of moderate to high environmental sensitivity. In this region are installed the main socioeconomic activities of RN State: salt industry, shrimp farm, fruit industry and oil industry. The oil industry suffers the effects of coastal dynamic action promoting problems such as erosion and exposure of wells and pipelines along the shore. Thus came the improvement of such modifications, in search of understanding of the changes which causes environmental impacts with the purpose of detecting and assessing areas with greater vulnerability to variations. Coastal areas under influence oil industry are highly vulnerable and sensitive in case of accidents involving oil spill in the vicinity. Therefore, it was established the geoenvironmental monitoring of the region with the aim of evaluating the entire coastal area evolution and check the sensitivity of the site on the presence of oil. The goal of this work was the implementation of a computer system that combines the needs of insertion and visualization of thematic maps for the generation of Environmental Vulnerability maps, using techniques of Business Intelligence (BI), from vector information previously stored in the database. The fundamental design interest was to implement a more scalable system that meets the diverse fields of study and make the appropriate system for generating online vulnerability maps, automating the methodology so as to facilitate data manipulation and fast results in cases of real time operational decision-making. In database development a geographic area was established the conceptual model of the selected data and Web system was done using the template database PostgreSQL, PostGis spatial extension, Glassfish Web server and the viewer maps Web environment, the GeoServer. To develop a geographic database it was necessary to generate the conceptual model of the selected data and the Web system development was done using the PostgreSQL database system, its spatial extension PostGIS, the web server Glassfish and GeoServer to display maps in Web

A reconstrução cirúrgica do ligamento cruzado posterior (L.C.P.) do joelho ainda permanece como um grande desafio terapêutico. Neste trabalho avaliamos 30 pacientes submetidos à reconstrução cirúrgica do L.C.P. com a técnica de fixação do enxerto tendíneo no leito tibial por abordagem direta (INLAY). 28 pacientes eram do sexo masculino e 2 do feminino, com idade média de 31,10 anos. O tempo médio de lesão foi de 34,24 meses em 67% dos casos a lesão foi secundária a acidente motociclístico. As lesões condrais e do ligamento cruzado anterior (L.C.A.) do joelho estavam presentes em 67% e 33% dos casos, respectivamente. Os pacientes foram avaliados objetivamente (teste de gaveta posterior) e subjetivamente (Escala de Lysholm). O seguimento pós-operatório médio foi de 21,7 meses. Cerca de 66% dos casos foram classificados como bom e excelente na avaliação subjetiva e objetiva. A análise estatística apresentou comportamento semelhante para as duas avaliações.Os resultados clínicos pós-operatórios obtidos neste trabalho têm nos encorajado a seguir com esta técnica cirúrgica.

Avaliamos 21 pacientes, sendo 16 pacientes do sexo masculino e 5 do feminino, com idade média de 30 anos, foram submetidos à tratamento cirúrgico da fratura-avulsão do LCP. em 57% dos casos a lesão foi secundária a acidente motociclístico e 19% a acidente automobilístico. em 72% dos casos foi identificada uma lesão na face anterior do joelho. O tratamento cirúrgico consistiu na abordagem posterior do joelho e fixação do fragmento ósseo com parafuso e arruela em 18 casos; e amarrilhas trans-ósseas em 3 casos, onde o fragmento ósseo era muito pequeno. em 91% dos casos, a cirurgia foi realizada dentro dos primeiros 15 dias apos a lesão. Os pacientes foram avaliados objetivamente (teste de gaveta posterior) e subjetivamente (Escala de Lysholm), apos um seguimento pós-operatório mínimo de 12 meses. A análise estatística não mostrou diferença significativa, ao nível de 5%, entre as avaliações objetiva e subjetiva. A ausência de lesão ligamentar periférica pode ter contribuído para que os resultados clínicos pós-operatórios tenham avaliação subjetiva satisfatória; entretanto, a presença de uma posteriorização tibial residual sugere que a fratura-avulsão do ligamento cruzado posterior deve ser abordada não como uma lesão óssea pura, mas sim, como uma lesão ósteo-ligamentar.

Biofilm formation is considered an advantage for Staphylococcus aureus mastitis isolates, facilitating bacterial persistence in the udder. It requires attachment to mammary epithelium, proliferation and accumulation of cells in multilayers and enclosing in a polymeric matrix known as exopolysaccharide. The objective of this study was to evaluate the ability of Staphylococcus aureus isolated from bovine subclinical mastitis for formation of biofilms. A total of 94 Staphylococcus aureus strains obtained from milk samples of cows suffering from subclinical mastitis in dairy herds on two properties in the state of São Paulo were evaluated. These strains were characterized by in vitro biofilm formation, and by the presence of icaA and icaD genes which are responsible for intercellular adhesion. The results revealed that 98.9% of the isolates produced biofilm in vitro by adherence in sterile 96-well "U" bottom polystyrene tissue culture plates; 95.7% of the isolates possessed the icaA and icaD genes. These bacterial isolates biofilm producers may impair eradication of chronic mastitis, rendering antibiotherapy less effective. The detection of biofilm forming ability in mastitis isolates may provide useful information for more adequate therapeutic regimen and for preventive actions in the control of those bacterial isolates in bovine herds.
