With a 4.9 μs working period for the 20 μm × 20 μm heaters that generate the deflecting jets, the sorter can potentially attain a working frequency of 50 kHz or higher.
About 52% of respondents were working in rural areas (n = 265), as staff nurses (n = 471, 92.7%), during morning working period (n = 440, 86.6%), for 45 hours per week (n = 331, 65.2%) and covered caseloads which included male clinics, female clinics, maternity and childhood, immunizations, home visits, chronic diseases, medical records and management.

The median nicotine concentration found in the venues of our study is associated with an excess lung cancer mortality risk of 438 per 100,000 in discos and 28 per 100,000 in restaurants, assuming a regular exposure (8 hr per working day) to these levels of SHS during a 40-year working period (derived using the formula of Repace and Lowrey 1993).

However, throughout the 8-month working period, their productivity was recorded on a weekly basis from the record register book (brick molders = 88 and brick carriers = 32; N =120) for three sessions, and it was calculated as productivity per person per week.
