As Master of the Queen's Music (let's not worry about redubbing her "Mistress", a word loaded with the contradictory atmospheres of schoolroom and boudoir), Weir becomes a necessary figurehead: visible, high-profile proof that women not only can compose, but can rise to hold the same title as Elgar himself.
More recently, Kent and Norris (2005) showed that at least 50 ng was necessary for visible amplification from mosquito abdomens.
In view of technical limitations and possible multiple steps necessary for "visible" LD formation, it is not easy to specify where in the process a particular factor(s) is involved.
The CdS/n-TiO2 was necessary for Visible-light response.
Chefs de cuisine have always been the workhorses who make every restaurant empire run, but they have never been more necessary, or more visible.
A combination of gene dosage, post-transcriptional, and post-translational regulation was necessary to allow visible color change over physiologically relevant ranges representing a small fraction of the regulator's dynamic response range, with further tuning possible by modulation of precursor availability.
Pigs unwillingly show signs of lameness [ 46], supporting the idea of a pain threshold in pigs and explaining why many OC lesions, but not single OCD lesions, seem necessary to generate visible lameness.
After establishing initial muscle contractions the needle was carefully repositioned in order to obtain the minimum current strength and duration (threshold) - with first reducing stimulus duration before current strength - necessary to generate visible muscle contractions.
The police were visible when necessary, but seemingly content to work in tandem with the youth leaders, too.
Photocatalysis based on TiO2 offers a sustainable pathway to drive chemical reactions, such as water splitting and contaminants decomposition, while band gap engineering of TiO2 is necessary to achieve a visible light response.
