2. 1. Condition measuring and lifetime modelling of disconnectors, circuit breakers and other electrical power transmission equipment

   Author : Per Westerlund; Patrik Hilber; Tommie Lindquist; William Q Meeker; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reliability; maintenance; condition monitoring; disconnector; circuit breaker; Weibull distribution; prediction; risk analysis; decision making; beta distribution; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The supply of electricity is important in modern society, so the outages of the electric grid should be few and short, especially for the transmission grid. A summary of the history of the Swedish electrical system is presented. The objective is to be able to plan the maintenance better by following the condition of the equipment. READ MORE

4. 2. Gamow -Teller Beta Decay in Drip Line Nuclei

   Author : Fredrik Frisk; Matematisk fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; gravitation; relativity; proton drip line; Gamow-Teller giant resonance; beta decay; Hartree-Fock calculation; prolate; oblate; deformed nuclei; Tamm-Dancoff approximation; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:1997:Frisk;

   Abstract : Before radioactive ion beams became available, the Gamow-Teller (GT) giant resonance was studied using charge-exchange reactions such as (p,n) and (He,t). In beta-stable nuclei, which can be used as targets, the GT giant resonance lies above the ground state of the mother nucleus. READ MORE

5. 3. Brain distribution of a bispecific antibody targeting Aβ

   Author : Gustavsson Tobias; Dag Sehlin; Stina Syvänen; Paul O'Callaghan; Danica Stanimirovic; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; amyloid-beta; blood-brain barrier; single-photon emission computed tomography SPECT ; bispecific antibody; immunotherapy; Molekylär medicin; Molecular Medicine; Neuroscience; Neurovetenskap;

   Abstract : Alzheimer’s disease (AD) is characterised by aberrant protein aggregation in the brain with subsequent synaptic loss, neuroinflammation, and brain atrophy that ultimately clinically manifests as cognitive impairment. Histopathological findings in AD are extracellular plaques of the protein amyloid-beta (Aβ), Aβ in blood vessels (CAA), and intracellular neurofibrillary tangles (NFT) of hyperphosphorylated tau.

6. 4. Edge correction and regression models for quantifying single-tree influence on understory vegetation

   Author : Sharon Kühlmann-Berenzon; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; beta distribution; ecology; edge effects; forestry; influence potential; logistic regression; statistical modeling; spatial point process; statistical modeling;

   Abstract : The understory is the layer of vegetation in the forest situated under the canopies of the trees. Some species of understory vegetation benefit from the surrounding trees, e.g by the provided nutrients, while others are restricted, e.g. READ MORE

7. 5. Linkage maps in studies of genetic variation - examples from Beta vulgaris

   Author : Thomas Kraft; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytogenetics; Genetics; Beta vulgaris; Linkage maps; genetic variation; Genetik; cytogenetik;

   Abstract : Today, most studies of genetic variation utilise molecular markers, making it possible to detect variation at the DNA level. This has greatly facilitated studies of genetic variation in population and evolutionary genetics, systematics and transmission genetics. READ MORE
