1. Avoiding ageing : Surface degradation of commercial electrode materials in lithium-ion batteries
Sammanfattning : The battery market today expands rapidly, not least for electric vehicles. But to compete against the combustion engine, the cost of batteries must be reduced. After years of usage, the batteries degrade and need to be exchanged, increasing the cost over the vehicle lifecycle. LÄS MER
2. Stretch-shortening cycle (SSC) muscle power, muscle strength and functional capacity in Scandinavian women and men - Effects of ageing
Sammanfattning : Ageing is associated with a gradual decline in physical function due to age-related loss of muscle mass, strength, and muscle power, leading to loss of independence. Physical therapists employ various tests to assess of physical functional performance, postural control, and muscle strength. LÄS MER
3. Active ageing among older Thai adults in north-eastern Thailand – implementing the Plan-Do-Study-Act cycle
Sammanfattning : Active ageing is agreed as the national agenda by the Thai Government to sustain the older population to live well in society as a valued resource. Activities to promote active ageing are often provided in group formats, initiated by health providers, and often without promoting capacity and responsibility to enhance active ageing by older adults themselves.

4. Selection in sperm and its consequences : Exploring haploid selection, ageing and epigenetic effects in sperm
Sammanfattning : Sexually reproducing eukaryotes are typically going through a biphasic life cycle with a diploid and a haploid phase. Unlike in plants where selection on haploid pollen genotypes is well established, the possibility of selection occurring in animal sperm is currently not known. LÄS MER
5. Diagnosis of the Lifetime Performance Degradation of Lithium-Ion Batteries : Focus on Power-Assist Hybrid Electric Vehicle and Low-Earth-Orbit Satellite Applications
Sammanfattning : Lithium-ion batteries are a possible choice for the energy storage system onboard hybrid electric vehicles and low-earth-orbit satellites, but lifetime performance remains an issue. The challenge is to diagnose the effects of ageing and then investigate the dependence of the magnitude of the deterioration on different accelerating factors (e.g. LÄS MER
