Child abuse prevention programs aim to prevent the occurrence and/or reoccurrence of child abuse and neglect. There are a number of different types of child abuse prevention programs; but do they work? And on what basis are we able to draw conclusions as to their effectiveness? In this paper, six different types of child maltreatment prevention programs… (More)
We report extreme self-compression of sub-µJ 30 fs pulses at 800 nm in Ar-filled hollow-core PCF, resulting in 4% conversion to deep UV light in the fundamental guided mode, pressure-tunable from 220–270 nm.
Variants shown by the orientation of the cover-plate and of the superior articular facets of the sacrum have a considerable influence on the lumbosacral biostatistics. This can be illustrated by parallelograms of forces. If we assume a certain force stressing upon the sacrum, we are able to calculate the distribution of stress upon the cover-plate and the… (More)
The orientation of the superior articular processes with regard to the upper end-plate of the sacrum does not depend on the inclination of the sacrum. This assertion can be made by interpreting certain angles already described in literature and may be confirmed by a research following strict biomechanic principles: The orientation of the articular processes… (More)
Vacuum-UV radiation between 145-155 nm is generated from 40 fs, 800 nm 6.8 μJ pump pulses in a 34 μm core-diameter kagomé-photonic crystal fibre (PCF) filled with 20-25 bar neon. Simulations confirm the mechanism as resonant dispersive-wave emission.
ii The National Child Protection Clearinghouse has operated from the Australian Institute of Family Studies since 1995. The Clearinghouse is funded by the Australian Government Department of Families, Housing, Community Services and Indigenous Affairs as part of its response to child abuse and neglect. The Clearinghouse collects, produces and distributes… (More)
High-energy, single-mode, coherent, ultrafast pulses of light - tunable from the vacuum-UV to the visible spectral region - can be generated in gas-filled hollow-core photonic-crystal fibers through a simple experimental scheme.
