Use of local intelligence to reduce energy consumption of wireless sensor nodes in elderly health monitoring systems.

The percentage of elderly people in European countries is increasing. Such conjuncture affects socio-economic structures and creates demands for resourceful solutions, such as Ambient Assisted Living (AAL), which is a possible methodology to foster health care for elderly people. In this context, sensor-based devices play a leading role in surveying, e.

Cyclotrimethylenetriphosphinic Acid.

The cyclotrimethylenetriphosphinic acid (1), isoelectronic to the cyclotriphosphoric acid, is formed in the hydrolysis of 1,1,3,3,5,5-hexakis(dimethylamino)-1λ ,3λ ,5λ -[1,3,5]triphosphinine. Compound 1 is stable to acids and bases. On heating for a longer period of time in D O each of the three methylene groups is monodeuterated.
