This work aims to identify changes in paleoceanographic conditions on the NW Iberian Continental Margin during the last ~40 ka BP. Paleotemperatures expressed as mean annual Sea Surface Temperature (SSTma) and paleoproductivities expressed as Export Productivity (Pexpma) were evaluated using the modern analog technique SIMMAX 28, based on planktonic foraminifera census counts. The study took into account the re...
The OMEX core KC 024-19 was studied aiming at to assess the influence of climate changes on the origin and transport of the sediments of the Galician continental slope, in the last 40 ka. The results show that sea level variation played a major role in the supply of the terrigenous sediments coming from the nearby continental areas, whose basement has a Variscan age. Additionally, coarse-grained clastic materia...
Avaliaram-se os efeitos cardiovasculares por um período de 24 horas, após a administração de solução salina hipertônica (NaCl) 7,5% ou em associação ao hidroxietilamido 130/0,4 (HES), em cães com hipovolemia induzida e tratados com cetamina levógira ou racêmica. Após a indução da hipovolemia, administrou-se NaCl 7,5% (4mL/kg) no grupo hipertônica levógira (GHL) e no grupo hipertônica racêmica (GHR) ou HES 130/0...
We examined changes in the array of antennal sensilla of three species of Triatominae (Triatoma infestans, Rhodnius prolixus, and R. pallescens) following their establishment for different periods in laboratory culture. In each case, the laboratory colonies were compared with conspecific samples taken directly from the field, by quantitative analysis of the sensilla arrays on the three distal segments of the an...
Avaliaram-se os efeitos da injeção epidural de amitraz (0,4mg/kg), xilazina (0,05mg/kg) ou dimetil sulfóxido 10% (5,0ml) sobre a freqüência cardíaca (FC), pressão arterial sistólica (PAS), freqüência respiratória (FR), motilidade ruminal (MR), temperatura retal (TR), altura de cabeça (AC) e latência das respostas a estímulos nociceptivos nas regiões da coxa (LECC) e coroa do casco (LRRM) de vacas. Houve diminui...
