One of the most important measures to prevent wild forest fires is the use of prescribed and controlled burning actions as it reduce the fuel mass availability. The impact of these management activities on soil physical and chemical properties varies according to the type of both soil and vegetation. Decisions in forest management plans are often based on the results obtained from soil-monitoring campaigns. Tho...
Portugal, as well as the Mediterranean basin, is favorable to the occurrence of forest fires. In this work a statistical analysis was carried out based on the official information, considering the forest fires occurrences and the corresponding burned area for each of the districts of the mainland Portugal, between 1996 and 2010. Concerning to the forest fires occurrence it was possible to identify three main re...

During the month of January of 2008 a borehole (Permamodel-Gulbenkian 1 — PG1) 26 m deep was drilled on the top of Mount Reina Sofia (275 m a.s.l.) near the Spanish Antarctic Station of Livingston Island, South Shetland Islands. Cores from1.5 mto about 26mdeepwere collected formeasuring several physical properties. The objective of the present work is to report the values of the thermal conductivity and the the...
THERMAL PROFILES IN URBAN CANYONS MEASURED WITH CAPTIVE BALLOONS IN THE LISBON DISTRICT OF TELHEIRAS – Captive balloons filled with standard helium and tinytalks (small low price thermal sensors/data loggers) are an effective way to probe the urban atmosphere for microclimatological purposes. This method can be important to establish the transferability of results to other areas with the same urban morphology a...
This paper presents a brief description of the "Moliceiro" robot that represented the University of Aveiro in the "Championat du Monde de Robotique Mobile" that took place in La Ferté-Bernard, France, from the 13th to the 19th of May, 1996.Basically, the robot had to follow a line on the floor, about 50m long, and overcome a few more difficulties. The project was based on infra-red analog sensors, low-po...
A existência de instituições de ensino superior (IES), em localizações diversas e dispersas ao longo do país, constitui, provavelmente, uma das características mais marcantes associadas à expansão deste grau de ensino em Portugal, nos últimos quase 40 anos. Este fenómeno é particularmente relevante uma vez que o grau de qualificação da população ativa portuguesa continua diminuto. A presença de IES nos diferent...
