There are several strategies whereby ethical approval is obtained: it may be deferred until consciousness is regained, waived entirely, obtained in advance (if a directive is available) or it may be obtained from a surrogate acting on behalf of the unconscious patient [ 2].
Advance directives were available for 27% of patients at admission (57% of patients who were unable to care for themselves prior to admission and 59% of patients with dementia).
By virtue of its greater accuracy and safety with respect to prenatal screening for common autosomal aneuploidies, NIPT has the potential of helping the practice better achieve its aim of facilitating autonomous reproductive choices, provided that balanced pretest information and non-directive counseling are available as part of the screening offer.
In Germany, both mapping (aerial surveys 1994 1998, GPS surveys in 2003 and ongoing research, University of Kiel) and monitoring (EU-Water Framework Directive, WFD) data are available and the distribution of eelgrass is available both as polygon and point information.
Finally, even when they are available, advance directives have little effect on surrogate decision-making.
The prospective advantages offered by such "dense" arrays are evident in those scenarios where the angular resolution of a conventional fixed-length ULA is coarser than the angular extension of scatterers surrounding the terminals, i.e., where potential margins exist for a capacity enhancement, that could be achieved if only more directive arrays were available.
The recently revised European BSS Directive (27) requires that clinical imaging guidelines are available in all EU Member States.
When noninvasive aids are available, invasive measures referred to in advance directives (eg, intubation) are often needed only temporarily.
The herein proposed directives have been inspired by the sets of rules for gene nomenclature that are available for Arabidopsis [ 20], rice [ 21], Medicago [ 22] and tomato [ 23].
For example, no fixed thresholds are available for the assessment of significant adverse effects on natural habitats protected under Council Directive 92/43/EEC (i.e. Natura 2000 areas).
