The UAB virtual campus, an essential platform for a European environment of higher education

Ponència presentada al congrés Virtual Campus 2006, celebrat el 23-25 de març de 2006 a BarcelonaThe university is currently immersed - within Europe - in a process of coordinating higher education with the adaptation into the new ECTS European credits, which implies changing from a teacher-centred model (teacher conveys knowledge) to a learner-centred model, a real challenge. From 1996, the Universitat Autònoma de Barcelona (UAB) is carrying out the "Campus Virtual de la UAB" project. This platform fulfils several roles that aim at providing an answer to this challenge: - It provides support to face-to-face teaching - It encourages teaching innovation - It promotes the creation of learning materials - It fosters communication - It favours monitoring the learning process - It favours self-learning and self-assessment - It enables blended teaching experiences This article will focus on how to use the communication and discussion functionalities between teacher and students, and between students themselves, and on monitoring the students' learning proces

In vitro evaluation of the effects of some acaricides on life stages of Rhipicephalus sanguineus (Acari: Ixodidae) Avaliação in vitro do efeito de alguns acaricidas nos estádios de vida do Rhipicephalus sanguineus (Acari: Ixodidae)

The action of five acaricides was evaluated on eggs, larvae, nymphs and adults of the ixodid tick Rhipicephalus sanguineus. The acaricides tested were: high cis-cypermethrin (0.01%) + DDVP (0.11%), coumaphos (0.05%), deltamethrin (0.0025%), amitraz (0.025%) and cypermethrin (0.015%). Eggs treated with high cis-cypermethrin and cypermethrin showed eclosion inhibitions of 72.1% and 67.3%, respectively, whereas coumaphos was much less effective (only 11.7%). Except for coumaphos, which resulted in 63.3% and 80.0% mortality of nymphs and unfed females, respectively, all compounds tested killed 100% of all tick stages to which they were exposed.<br>Avaliou-se a ação de cinco acaricidas em ovos, larvas, ninfas e adultos do carrapato Rhipicephalus sanguineus.

Os ovos tratados com cipermetrina high cis e cipermetrina mostraram inibição de eclosão de 72,1% e 67,3%, respectivamente, enquanto coumaphos resultou em baixa eficiência (11,7%). Exceto para ninfas (63,3%) e para fêmeas não alimentadas (80,0%) expostas ao coumaphos, todos os outros estádios de carrapato e fêmeas não alimentadas foram sensíveis a todos os produtos químicos testados
