Which stream wood becomes functional following wildfires?
Vaz, Pedro; Merten, Eric; Warren, Dana; Robinson, Christopher; Pinto, Paulo; Rego, FranciscoLarge wood is a critical element in stream ecosystems, but only a subset of wood pieces actually provide hydraulic, geomorphic, and ecological functions. We test the current paradigm that larger pieces provide more function, and examine the role wildfires may play in affecting functionality of recruited wood. We conducted a cross-basin analysis in nine central Portugal watersheds, obtaining a variety of measure...

Maria Eugénia Pinho; Mário Vaz; Pedro Arezes; José Reis Campos; Barbedo MagalhãesRegular physical activity promotes better general state of health and is essential for the prevention of many illnesses, including musculoskeletal disorders. The promotion of both physical activity and its beneficial effects on health have contributed to the fast growth in the number of children and adolescents involved in organized or recreational sports activities which, unfortunately, has been followed by a ...

Risco e Profilaxia do Tromboembolismo Venoso em Doentes Cirúrgicos
Introdução: O Tromboembolismo Venoso (TEV) assume-se como uma das maiores causas de morbimortalidade prevenível em doen tes hospitalizados, constituindo assim um importante problema de saúde. A cirurgia condiciona um estado pró-trombótico, havendo necessidade comprovada de usar tromboprofilaxia adequada à estratificação de risco nestes doentes. Apesar das evidências da boa rela- ção custo-benefício, das guideli...

Small bowel metastatic of malignant melanoma: a rare cause of lower gastrointes...
Vaz, Pedro Silva; Usurelu, Sergiu; Monteiro, Ana; Correia, Sara; Gouveia, António; Loureiro, ArnandinaThe malignant melanoma is the most common cause of metastatic lesion in the gastrointestinal tract, representing about 33% of all the metastatic malignant tumors of the digestive tract. In 35% of patients the small bowel is impaired, and lower gastrointestinal bleeding is a rare form of presentation. The authors report a case of a 81-year-old male with a history of malignant skin melanoma excised in 1994. Under...
Ancient and Medieval Battles Conceptualization and Simulation
Pedro Moraes Vaz; Pedro A. Santos; Rui PradaEste trabalho apresenta um modelo do desenrolar de uma batalha da antiguidade ou medieval, e de como esta era entendida do ponto de vista do comandante do exército. Com base no modelo foi criada uma plataforma de simulação que permite a jogadores tomarem o papel de um general em batalhas da antiguidade ou medievais. A plataforma permite aos jogadores criarem planos tácticos que descr...

Synthesis and catalytic properties of manganese(II) and oxovanadium(IV) complex...
Fernandes, Tiago A.; Nunes, Carla D.; Vaz, Pedro D.; Calhorda, Maria José; Brandão, Paula; Rocha, João; Gonçalves, Isabel S.; Valente, Anabela A.Reaction of [MnIII(acac)3] and [VIVO(acac)2] with the 1,4-diazabutadiene (DAB) ligands Ph-DAB-(CH2)3R [R = Si(OEt)3(1a); H (1b)] (L) leads to complexes of the type [MnII(acac)2L] and [VIVO(acac)L]Cl in good yields. These complexes were characterised by spectroscopic techniques, and magnetic measurements showed that in the case of the manganese the metal was reduced during the reaction with the nitrogen ligand. ...
A categorification of the quantum sl(N)-link polynomials using foams
Vaz, Pedro Miguel dos Santos Santana ForteTese de dout., Matemática, Faculdade de Ciências e Tecnologia, Universidade do Algarve, 2008 ; In this thesis we define and study a categorification of the sl(N)-link polynomial using foams, for N 3. For N = 3 we define the universal sl(3)-link homology, using foams, which depends on three parameters and show that it is functorial, up to scalars, with respect to link cobordisms. Our theory is integral. We sh...
