The Cabrera vole (Microtus cabrerae) is a rare rodent living in patchy grassy areas of the Iberian Peninsula where unpaired individuals of both sexes use scent marking primarily to increase their mate-finding likelihood. Cabrera voles establish long-term pair bonds with opposite-sex conspecifics constituting a breeding pair, which is expected to reduce the efforts in searching for a new mate. Under such circums...
The alarm pheromones often released by animals under stressful situations seem to elicit behavioral changes in conspecifics, which in the appropriate context can be viewed as anti-predatory responses. However, the releasing of alarm pheromones associated with predatory events has not been demonstrated in mammals. In the current study with wild-caught Cabrera voles, we carried out experiments in the laboratory a...

We have created an interactive storytelling system for public spaces that is collaborative, easy and entertaining to use, and allows for a natural inte-raction. The system consists of a table, a ceiling mounted projector that projects onto the table, and a 3D camera for tracking hands and for object recognition. The main feature of the system is the projection on top of the palm of the hand of the users; thus, ...
No presente estudo efectua-se a modelação e análise do comportamento estrutural da estação Faria Guimarães, do Metro do Porto. A estação é constituída por um cruzamento oblíquo de duas grandes galerias executadas através do método SEM/NATM. A obra é de elevada complexidade devido aos condicionamentos geométricos da estação e obras adjacentes, à grande heterogeneidade do maciço e à ocupação intensa da superfície...
O envolvimento do sistema nervoso central na paracoccidioidomicose tem sido pouco descrito na literatura, sendo rara sua apresentação sob a forma meníngea. Descreve-se o caso de um paciente de 23 anos que desenvolveu meningite paracoccidioidomicótica comprovada pela positividade do fungo na pesquisa direta e cultura do líquido cefaloraquidiano. Discute-se a apresentação da forma meníngea da paracoccidioidomicos...
A 73 year-old white male, living in the interior of the state of Mato Grosso do Sul, in central Brazil, after an initial diagnosis of sinusitis was transferred to the neurology service with a 3-day evolution of intracranial hypertension. Exams showed lymphocytic leukemia and a tumor-like lesion, either an expanding inflammatory process such as an abscess or a neoplasm. Treatment with Ceftriaxone and Decadron w...
