People differ in their diurnal (time-of-day) preferences—some are morning-types and others are evening-types. These differences are explored in a unique experiment design in which subjects are randomly assigned to produce paper airplanes at either 8:00 a.m. or 10:00 p.m. Our results show that evening-types, at their more optimal time-of-day (10:00 p.m.), produce planes that fly statistically si...

This paper reports on formaldehyde exposure and its health hazards in a melamine manufacturing industry. The mean of workers' exposure was measured according to 3500 NJOSH and was found to be 1.44±O.2l, and 2. 17±O.24 ppm in morning and evening shifts, respectively. For stationary ones it was 1.37±O.20, and 2.06±O.25ppm, respectively. The results show that formaldehyde concentration at the...

Additionally, 94...
