A Toxoplasma gondii genomic library was constructed in lambda EMBL3. Repeated fragments were detected by hybridization with radiolabeled total DNA from the parasite and one recombinant was chosen due to its strong hybridization signal. By using electrophoretic and hybridization analysis, four cross-hybridizating restriction fragments were selected and(More)
The aim of this paper is to report the initiative of a research project called the CSCW Lab. The CSCW Lab is an approach for applying evaluation methodologies in the context of a groupware research group. We identify the major dimensions of groupware evaluation and describe how the CSCW Lab addresses them. The first experiments using CSCW Lab are also(More)
The aim of this paper is to sum up our first observations on the use of the context concept in software development applications – specially the collaboration supporting tools – in order to improve software organization's knowledge management and, furthermore, its organizational learning. This work proposes a framework for identifying and organizing(More)
Complexity and dynamism of day-today activities in organizations are inextricably linked, one impacting the other, increasing the challenges for constant adaptation of the way to organize work to address emerging demands. In this scenario, there are a variety of information, insight and reasoning being processed between people and systems, during process(More)
Team's composition of is key factor to its success, but differences between individual and collective interests result in obstacles for the configuration of teams. Considering only individuals skills is not enough to assemble a working group. We present Team Composer, an application based on Genetic Algorithm that implements a social matching strategy that(More)
Pathological aspects of a subclinical form of experimental canine leishmaniasis is reported here for the first time. Fifteen mongrel dogs were used in the present study. Eight dogs were infected and seven were used as control. Four of the control dogs were inoculated with spleen cells from non-infected hamsters. The eight mongrel dogs inoculated(More)
Toxoplasma gondii is a worldwide protozoan parasite which causes severe disease in congenitally infected children and in immunocompromised patients. Besides the well-defined cytoplasmic and membrane antigens of tachyzoites, we felt that excreted/secreted antigens could play a major role in the immune response. We first report the development of a(More)
