1. Ontogeny and Population Biology of a Sex-Limited Colour Polymorphism
Sammanfattning : This study has involved investigation of number of populations of the damselfly Ischnura elegans over several years, looking at frequency changes over time, morphological differences between the sexes and the morphs, differences in growth rate and development time, differences in fecundity between the morphs, and genetic differentiation between populations. I. LÄS MER
2. Membrane-based nanocalorimetry for low temperature studies with high resolution and absolute accuracy
Sammanfattning : A differential, membrane-based nanocalorimeter has been designed and constructed for thermal studies of mesoscopic samples at low temperatures. The calorimeter is intended for sample masses from mg to sub-μg and a broad temperature range from above room temperature down to the sub-K region. LÄS MER
3. On the forced oscillation lung function test and its design for use in children
Sammanfattning : .... LÄS MER
4. Modelling of cavity partial discharges at variable applied frequency
Sammanfattning : The presence of partial discharges (PD) in high voltage components is generally a sign of defects and degradation in the electrical insulation. To diagnose the condition of high voltage insulation, PD measurements is commonly used. LÄS MER
5. Partial discharges in cylindrical cavities at variable frequency of the applied voltage
Sammanfattning : Measurements of partial discharges are commonly used to diagnose the insulation system in high voltage components. Traditionally a single xed frequency of the applied voltage is used for such measurements as in the Phase Resolved Partial Discharge Analysis (PRPDA) technique. LÄS MER
