Within each of eight Southern California communities, up to 29 locations were sampled for rotating, month-long integrated periods at two different times of the year, six months apart, from Nov 2008 through Dec 2009.
The basic unit of observation that represents the integrated exposure period measured is a person-period for the food (4 days), urine (first morning void), and hair (1.5 months) data, and a household-period for the drinking water and dust data.
Japanese schools have an "integrated studies" period designed to improve problem-solving skills.
The sulfur fraction of the PM on the school-site filters was not associated with an increase in any of the symptom outcomes for either of the integrated time periods, and school-hour weekday sulfur concentrations were not associated with either of the afternoon lung function metrics.
To the best of the authors' knowledge, multi-period integrated gas and electric system optimal power flow (M-GEOPF) has not been formulated based on precise nonlinear electric power and gas flow models.
Based on these motivations, we propose a multi-period integrated natural gas and electric power system probabilistic optimal power flow (M-GEPOPF) model, which includes dynamic gas flow models.
Additional techniques are available including composite sampling and the use of passive samplers (e.g., polar organic contaminant integrative sampling, POCIS) which give an integrated sample over a period of days to weeks.

9 This authorization led to the establishment of NTD Control Program of the United States Agency for International Development (USAID) that envisioned, over a five-year period, facilitating integrated NTD programs in 15 countries.
The urinary profiles of As species have been shown to reflect only a recent exposure to iAs; however, the concentrations of As species in BECs are likely to reflect the integrated exposure over a period of about 200 days, the lifetime of the superficial layer of bladder epithelium (Born et al. 2003).
