Since the latest update of the checklist on bees known from Denmark, the following three species have been added as new to the country: Colletes halophilus Verhoeff, 1943 (Colletidae), Nomada obscura Zetterstedt, 1838 (Apidae) and Xylocopa violacea (Linnaeus, 1758) (Apidae). The national checklist hereby includes 286 bee species, but more species will probably be found in the future, as the wild b

Selective vulnerability in neurodegeneration: insights from clinical variants of Alzheimer's disease.

Selective vulnerability in the nervous system refers to the fact that subpopulations of neurons in different brain systems may be more or less prone to abnormal function or death in response to specific types of pathological states or injury. The concept has been used extensively as a potential way of explaining differences in degeneration patterns and the clinical presentation of different neurod

Third trimester assessment of the uterine scar in women with prior caesarean: what is the evidence?

The increasing rate of caesarean delivery is a worldwide concern. A major contributor to this evolution has been a concomitantly decline in vaginal birth after caesarean, because of the risk of intrapartum uterine rupture, which is a rare but potentially catastrophic complication of a trial of labour after caesarean (TOLAC). On the other hand, elective repeat caesarean is associated with surgical

Effects of Walking Speed and Results of Timed Get-Up-and-Go Tests on Quality of Life and Social Participation in Elderly Individuals With a History of Osteoporosis-Related Fractures.

OBJECTIVE: To investigate the relationships between physical performance, quality of life (QoL), and social participation among elderly men and women with a history of osteoporosis-related fractures. METHOD: The study was a population-based cross-sectional study including 155 participants aged 60 to 93 years from the Swedish longitudinal investigation, "Good Aging in Skåne." The participants had s

How In-Service Experience Informs Design Modifications: A Case Study in Aero Engines

This research is triggered by a fundamental shift that is occurring in the manufacture and marketing of aero engines for commercial and defence purposes, away from the selling of products to the provision of services. Under the emerging ‘power by the hour’ paradigm, aero engines are effectively leased to the airlines, with the manufacturing company remaining responsible for their maintenance and r

Rapidity density distributions in 16O, 28Si, 32S, 197Au, and 208Pb induced heavy-ion interactions at 4A–200A GeV

The mass, energy, and centrality dependence of rapidity density distributions of relativistic, charged particles, produced in heavy-ion interactions in the energy range 4A–200A GeV, are investigated. The results indicate that the rapidity density distributions show systematic variations, which are used to predict distributions for Au+Au and Pb+Pb interactions in a model-independent way.
