1. Cervicothalamic tract termination and its cortical connections: anatomical studies in cats and ferrets
Sammanfattning : The termination and cortical connections of the cervicothalamic tract (CTT) were studied by neuroanatomical tract tracing techniques in cats and ferrets. After injections of wheat germ agglutinin-horseradish peroxidase conjugate or biotinylated dextran amine (BDA) into the cat lateral cervical nucleus (LCN), the most abundant CTT termination is present in the ventral posterior lateral nucleus (VPL).

2. Iron nutrition dynamics - Differences between calcicole and calcifuge plants
Sammanfattning : One third of the earth´s soils is calcareous. Calcifuge plants are excluded from these soils, and one of the main causes is Fe deficiency, as Fe solubility in calcareous soil is very low. A lack of Fe lowers chlorophyll content, visible as yellowing of leaves, called chlorosis. LÄS MER
3. Role of cadmium and ultraviolet-B radiation in plants, Influence on photosynthesis and element content in two species of Brassicaceae
Sammanfattning : Plants are exposed to many different stress factors during their lifetime, often more than one factor at a time, which highlights the importance of research regarding interaction among stress factors. Cadmium and ultraviolet-B radiation (UV-B, 280-315 nm) are two potential stress factors in the environment, which have gained increased interest due to atmospheric pollution. LÄS MER
4. A multi-scale approach for predicting the fire response of building barriers
Sammanfattning : Building barriers are compartmentation elements in buildings that limit the passage of fire and smoke to adjacent spaces. They are key elements in the overall response of a building in a fire. The adequate fire response of building barriers is usually assessed by the fulfilment of standardized resistance to fire tests.

5. Method development for isotope analysis of trace and ultra-trace elements in environmental matrices
Sammanfattning : The increasing load of toxic elements entering the ecosystems, as a consequence of anthropogenic processes, has grown public awareness in the last decades, resulting in a great number of studies focusing on pollution sources, transport, distribution, interactions with living organisms and remediation. Physical/chemical processes that drive the uptake, assimilation, compartmentation and translocation of heavy metals in biota has received a great deal of attention recently, since elemental concentrations and isotopic composition in biological matrices can be used as probes of both natural and anthropogenic sources.
