FAdo is an ongoing project which aims to provide a set of tools for symbolic manipulation of formal languages. To allow high-level programming with complex data structures, easy prototyping of algorithms, and portability (to use in computer grid systems for example), are its main features. Our main motivation is the theoretical and experimental research,(More)
OBJECTIVE To determine whether the presence of orthostatic hypotension--which, in this age-group, could be due to varying degrees of autonomic dysfunction--is an indicator of nocturnal arterial hypertension. PATIENTS Between 1999 and 2001 we prospectively and consecutively studied 93 elderly patients with untreated (office) arterial hypertension, 65 (70%)(More)
Developed societies are currently facing severe demographic changes: the world is getting older at an unprecedented rate. In 2000, about 420 million people, or approximately 7 percent of the world population, were aged 65 or older. By 2050, that number will be nearly 1.5 billion people, about 16 percent of the world population. This demographic trend will(More)
BACKGROUND Eventual relationships between the vascular function and transepidermal water loss (TEWL), in vivo,have not been entirely explored. By promoting local perfusion alterations through a well-known challenge test, the'tourniquet-cuff occlusion' manoeuvre, the present study searches for other dynamical factors influencing the cutaneous barrier,(More)
We present an interactive graphical environment for the manipulation of context-free languages. The graphical environment allows the editing of a context-free grammar, the conversion to Chomsky normal form, word parsing and the (interactive) construction of parse trees. It is possible to store positive and negative datasets of words to be tested by a given(More)
INTRODUCTION Diabetes mellitus has a prevalence of about 6 to 10% in western populations, with a rising tendency due to inappropriate increases in calorie intake and decreased physical activity. In diabetic patients hypertension (HT) has a prevalence of over 60% and cerebro- and cardiovascular disease is responsible for two-thirds of the mortality in these(More)
Leishmania humoral and cellular immune responses in naturally infected symptomatic and asymptomatic dogs. Comparison of grazing behaviour, dietary overlap and performance in non-lactating domestic ruminants grazing on marginal heathland areas. A case-control study of risk factors for brucellosis seropositivity in Portuguese small ruminants herds. A. 2007.(More)
