2. 1. Cervicothalamic tract termination and its cortical connections: anatomical studies in cats and ferrets

   Author : Mengliang Zhang; Institutionen för experimentell medicinsk vetenskap; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; Carnivora; Cytoarchitecture; Immunocytochemistry; Compartmentation; Retrograde transport; Anterograde transport; Somatosensory cortex; Thalamus; Spinal cord; Lateral cervical nucleus; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Abstract : 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).

4. 2. Iron nutrition dynamics - Differences between calcicole and calcifuge plants

   Author : Angelika Zohlen; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; 10-phenanthroline; 1; chlorophyll; plaque; root; leaf; immobilization; plants; calcifuge; Iron; calcicole; Plant ecology; Växtekologi;

   Abstract : 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. READ MORE

5. 3. Role of cadmium and ultraviolet-B radiation in plants, Influence on photosynthesis and element content in two species of Brassicaceae

   Author : Helene Larsson Jönsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; UV-B; plant nutrients; photosynthesis; oxygen evolution; chlorophyll fluorescence; Cd uptake; cadmium; Arabidopsis thaliana; Brassica napus; Plant biochemistry; Växtbiokemi; Botany; Botanik;

   Abstract : 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. READ MORE

6. 4. A multi-scale approach for predicting the fire response of building barriers

   Author : Blanca Andrés Valiente; Avdelningen för Brandteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire; Building Barriers; Heat transfer; Experimental; Gypsum; Stone wool; furnace; H-TRIS;

   Abstract : 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.

7. 5. Method development for isotope analysis of trace and ultra-trace elements in environmental matrices

   Author : Nicola Pallavicini; Ilia Rodushkin; Johan Ingri; Frank Vanhaecke; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

   Abstract : 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.
