During the last decades of the XX century occurred several demographic, cultural and social changes that directly affected the inclusion of women in the labor market. However many of them have found and still find barriers to work in various fields of endeavor and in the case of this study, the sports management. The purpose of this study was to assess through a systematic review, the participation of women in sports management, listing the main characteristics, challenges and difficulties. The research consisted of a systematic review of studies that discuss the thematic related to the participation of women in sport management in Brazil, including the Google Scholar database. The key words used and that generated proceeds were woman, sports management and women in sports administration. In the discussion and results has been possible to list the insert forms in a management position, the main ones being: by invitation, conduction or family relationship. The arguments about the limited participation of women in sports management and their encountered barriers are justified because there is a male domain and prejudice, resulting often the career waiver for these women. The profile of the sporting managers has found a predominance of men aged between 30-49 years old. For unavailability of articles, the present study was restricted to use only one database. In short, there is a lacuna in studies on women's participation in the administration or sporting management, with a prevalence of literature review articles. To expand overview on this issue would be important to carry out quantitative studies. It was concluded that the difficulty of women entering in sports management still seems to be a current problem and can only be minimized from a greater attention from the scientific community. It is suggested to carry out further studies that address more deeply the reasons for this disparity, aimed at proposing specific changes to the...

Time series tendencies are an important tool for different sectors such as the scientific community, industries and environmental protection agencies who can evaluate the variability of a specific parameter in time, what is very important piece of information for establishing corrective and preventive actions. This work presents a time series model of main physical, chemical and biological parameters of the Water Quality Index (WQI) determined for different selected points of a hydrographical basin form May/2006 to Aug/2010. The statistical model Arima enabled a better understanding of the physical, chemical and biological processes that most clearly influences WQI. The Arima model allowed the assessment of the trend of several parameters used in the calculation of the WQI, showing that dissolved oxygen, turbidity, total nitrogen, and fecal E. coli were highly correlated and are the parameters that caused the index changes over time.

Workings related insects macro-photographs production are little widespread in the scientific community. However, the use of images has wide application, serving for scientific publications, conferences, courses, databases and development of illustrated identification keys. Thus, methodologies were developed to assist in capturing and processing highresolution images, improving its quality, without, however, their technical characteristics.

Seasonal variation in the biomass and primary productivity of the periphyton on natural substratum (internodes of Echiiwchloa polystaclya HBK Hitch.) was studied during one year (from August 1993 to July 1994) in a lagoon with permanent connection with a river. We also analysed the relationships between the hydrological regime, climatic conditions and physico-chemical variables of water with the biological compounds of the periphyton. Values of dry mass, ash-free dry mass, chlorophyll a and phaeophytin of periphyton ranged from 0.55±0.24 g m-2 to 7.86±4.93 g m-2; 0.28±0.18 g m-2 to 3.72±2.23 g m-2; 0.57±0.09 mg m-2 to 15.57±4.52 mg m-2; 0.03±0.03 mg m-2 to 4.74±3.46 mg m-2, respectively. The primary productivity of periphytic algae measured by C14 method ranged from 6.45±1.29 mg C m-2 h-1 to 52.88± 7.55 mg C m-2 h-1. The biomass showed a peak in October 1993, February and April 1994. Higher value of primary productivity was recorded in December 1993 and January 1994 and was due to the peculiar light and nutrition conditions during this period. We conclude that biomass and productivity of the community are controlled mainly by hydrological regime (fluctuations of water level). © INTERNATIONAL SCIENTIFIC PUBLICATIONS.

Community acquired methicillin Staphylococcus aureus (CA-MRSA) was first reported in 1981, infecting people without risk factors. These strains harbor the Staphylococcal Cassette Chromosome mec (SCCmec) type IV, which contains the mecA gene codifying for methicillin resistance. CA-MRSA strains usually carry PVL (Panton-Valentine Leukocidin), a virulence factor responsible for tissue invasion, causing systemic infections and leading to serious complications. The aims of this work were to detect the mecA gene, SCCmec characterization and to detect the PVL gene of the S. aureus strains isolated from patients diagnosed with skin and soft tissue infections attending the Dermatology Service, of the Botucatu Medical School, Brazil. Among 127 collected samples, 66 (51.9%) were S. aureus and, from these, 7 (10.6%) harbored mecA gene, 3 (42%) with cassette type IV, and none of these samples carried the PVL gene, but it was detected in 10 (15.1%) samples of S. aureus methicillin sensitive (MSSA). Our study suggests the S. aureus strains that harbor PVL gene and MRSA are present in the community as important pathogens.
