The present study aimed to gather baseline information about chimpanzee nesting and density in Lagoas de Cufada Natural Park (LCNP), in Guinea-Bissau. Old and narrow trails were followed to estimate chimpanzee density through marked-nest counts and to test the effect of canopy closure (woodland savannah, forest with a sparse canopy, and forest with a dense(More)
BACKGROUND Understanding the ecological consequences of roads and developing ways to mitigate their negative effects has become an important goal for many conservation biologists. Most mitigation measures are based on road mortality and barrier effects data. However, studying fine-scale individual spatial responses in roaded landscapes may help develop more(More)
In this article we describe a new wireless biosignal system which monitors in a long-term basis, the users at their homes. The system consists of wearable sensors that measure heart rate, blood oxygen saturation and physical activity levels, sending data to a mobile phone and from this to a remote monitoring station located in a clinical facility. Whenever(More)
This study presents a signal-independent algorithm, which detects significant events in a biosignal, without previous knowledge or specific pre-processing steps. From a morphological analysis, the algorithm computes the instants when the most significant standard deviation discontinuities occur. An iterative optimization step is then applied. This assures(More)
5-alpha reductase (5α-reductase) is a microsomal protein that converts testosterone into dihydrotestosterone (DHT). When changes occur in the function of this enzyme, disorders such as pseudohermaphro-ditism, baldness, benign prostatic hyperplasia and prostate cancer may arise. Currently, there are only two marketed drugs, finasteride and du-tasteride, for(More)
