Human breath is known to contain trace amounts of volatile organic compounds (VOCs) such as acetone, methanol, ethanol, aldehydes, and alkanes, typically in parts-per-billion (ppb) or parts-per-trillion (ppt) molar fraction ranges.
In the locker room during the break, Roddick huddled with Brad Gilbert, typically promoted (in part by himself) as the best coach in tennis.
Even so, people who have spent time with him say Mr. Kennedy is talking more about his past and that of his family than he typically has, in part because he is writing a memoir and it stirs memories.
Construction of the maps typically entails, in part, rectifying the satellite images to a geographic coordinate system, observing ground plots whose coordinates are obtained from Global Positioning System (GPS) receivers that are calibrated to the same geographic coordinate system, and then matching ground plots to image pixels containing the centers of the ground plots.
The low limestone islands tend to be significantly older and typically formed (in part at least) from reefs that were living around 6 m above present sea level during the Last Interglacial period, around 125,000 years ago and sometimes during earlier Quaternary interglacial periods.
Midterm elections typically serve in part as a referendum on the party in power, but local and regional issues often play a role too.
Similarly, ES cell differentiation pathways are typically directed, in part, by sequential activation of receptor-mediated intracellular signaling pathways by peptides and other molecules [6], [7], [8].
In diverticulosis, small pouches develop and bulge out through weak spots in the walls of the colon, typically in the part of the colon called the sigmoid colon on the left side of the abdomen.
Volatile sulfur compounds are typically in the parts per trillion (ppt) range to low parts per billion (ppb) range [32], however, they are normal components of wine, beer, cheese or cooked meat aroma, and can even exert a decisive role on some characteristic sensory descriptors [33].
Polytechnics of the past provided specialist and technical training, typically in shorter, part-time or day-release formats, that prepared their students for a specific goal and a different sort of qualification.
Trace element concentrations are typically expressed in parts per million.
