THERAPEUTIC STRATEGIES FOR TREATING ACTINIC KERATOSIS - A REVIEW
Lopes, José Campos; Especialista de Dermato-venereologia/Graduated Consultant of Dermatology and Venereology, Hospital da Luz, Lisboa, PortugalThe most important question associated with the actinic keratosis is their 5 to 10% probability to evolve to invasive squamous cell carcinoma of the skin. The progressive increase of actinic keratosis prevalence and the difficulty in predicting their evolution pattern have determined the importance of its adequate prevention and treatment. The current review describes the different treatment options for the act...

AMS and IRM studies in the late-variscan Santa Eulália Plutonic Complex (Ossa-M...
Nogueira, Pedro; Carrilho Lopes, JoséThe Santa Eulália Plutonic Complex (SEPC) is a calc-alkaline granitic body, with an area of 400 km2, and is located in the north of the Ossa Morena Zone of the Variscan Iberian sector, near the limit with the Central Iberian Zone. SEPC is considered late-Variscan because it cross-cuts the regional variscan structures. The host rocks are metamorphic formations from Upper Proterozoic to Lower Paleozoic. The SEPC ...
Redes Ethernet: de 1 Mbit a 1 Gbit
Rui Pedro Lopes; José Luís OliveiraNowadays, around 80% of local area networks are Ethernet based. However, aside from all the criticism over Ethernet technology, the market share does not tend to decrease. The growth of transmission speed, introduced with Fast Ethernet and, more recently, with Gigabit Ethernet, keeps the technology up to date, in despite of some limitations introduced by the compatibility with prev...

On the Use of Thermal Properties for Characterizing Dimension Stones
Amaral, Paulo; Correia, António; Lopes, Luís; Rebola, Paula; Pinho, António; Lopes, José CarrilhoThe use of dimension stones in architecture and civil engineering implies the knowledge of several mechanical, physical, and chemical properties. Even though it has been usual practice to measure physical and mechanical properties of dimension stones the same is not true for thermal properties such as thermal conductivity, thermal diffusivity, specific heat capacity, and heat production. These properties are pa...

Lopes, José Carrilho; Sant'Ovaia, Helena; Nogueira, Pedro; Martins, Helena; Noronha, Fernando; Lopes, LuisThe Santa Eulalia Plutonic Complex (SEPC) is a late-Variscan granitic massif with elliptical contours intersecting the NW-SE Variscan dominant regional structures in the most northerly sectors of the Ossa-Morena Zone (Iberian massif). The host rocks of this plutonic complex are meta-sedimentary formations generated between Proterozoic and Lower Paleozoic, some of them strongly affected by contact metamorphic pr...
