Thermal conductivity and thermal diffusivity of cores from a 26 meter deep bore...

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...

LOW-COST DATA LOGGERS FOR AIR, SOIL AND ROCK TEMPERATURE MONITORING -Tiny Talk II data loggers were adapted in the laboratory of the Centro de Estudos Geográficos for air, soil and rock temperature monitoring. The loggers are single-channel 8 bit devices with a 2K EEPROM memory that allows the registration of 1,800 temperature records at user-defined intervals. Temperatures are measured by NTC100 thermistors se...

Close to the Spanish Antarctic Station our research team drilled, at the 1999-2000 Antarctic campaign, a 2,30 m shallow borehole in quartzite bedrock. This borehole was instrumented with temperature data loggers (Tinytag model) that have allowed us to register the gradient thermal in a continuous regime evolution during the 2000-2011 period. The analysis of the temperature data allows to describe the temporal e...

When do people derogate or psychologically distance themselves from victims? Be...

Two factors increase the threat for individuals’ belief in a just world (BJW) posed by an innocent victim: the degree of the observer’s explicit endorsement of BJW and the fact that the victim shares a common identity with the observer. In this paper, we aim to investigate whether or not these two factors (BJW and ingroup identification) have an interaction effect on each of two mechanisms that reduce the threa...

Mestrado em Biologia Funcional - Instituto Superior de Agronomia ; The cork oak (Quercus suber) is an important species in Portugal, mainly due to the economic value of the cork it produces. Cork is produced by phellogen. In cork oaks, this meristematic tissue has few discontinuities and has a peak of activity in the spring. Every phellogen discontinuity will degenerate into cork defects, being pores and nail ...
