The observation dates for the riverine, ground, and stream waters are described in Table 1.
Milder symptoms affect most women, an observation dating back to the time of Hippocrates.
These observations date primarily from between about 700 and 50 bce.
Furthermore, we track the long-term deployment history of new TLS security features by leveraging passive observations dating back to 2012.
Yet observations dating back nearly six decades demonstrate that bacteria exhibit precise regulation of growth and form robust across multi-fold changes in mass.
The first to see something interesting was the DAMA experiment, located under 1.5km of rock at Gran Sasso in Italy: its observations date back to the late 1990s and the evidence has strengthened with time.
They make several detailed predictions about Lutetia based partly on observations dating back to the 1960s but mostly on data taken since 2004, when interest picked up after the asteroid was chosen as a flyby target.
The first Florida Keys observations date back to the early 1970s, when multiple pairs, all of the South American urubitinga subspecies, were observed; these observations, now typically of single birds, have continued into the 2010's.
After they crunched the numbers, combining the current monitoring system's data with satellite observations dating back to 1982, they noticed that terrestrial plant growth, also known as net primary production, remained relatively constant.
(It should, however, be remembered that the origin of these observations date back to the 1960 ies/1970 ies when the Kraepelian type of depression was much more frequently presented in psychiatric hospitals).
