Development Of Circadian Sleep-Wakefulness Rhythm In A Healthy Boy Gauged By Circadian Quotients, Ellen Reeker, Michael Diffley
Development Of Circadian Sleep-Wakefulness Rhythm In A Healthy Boy Gauged By Circadian Quotients, Ellen Reeker, Michael Diffley
Journal of the Minnesota Academy of Science
The circadian quotient, briefly CQ, serves to estimate the prominence of a rhythm with a period of about 24 hours. The CQ may be computed from so-called variance spectrum analysis, among other procedures ( 1) . Computational details and some applications have been discussed earlier (1 , 2). We wish to illustrate herein the use of the CQ for gauging the development of a circadian sleep-wakefulness rhythm in the senior author's first-born child, FAR, also documented in general terms, elsewhere ( 3).
Apparent Effects Of Refrigeration On The Rate Of Embryonic Development Of Mayfly (Hexagenia Limbata) Eggs, Roger Flattum
Apparent Effects Of Refrigeration On The Rate Of Embryonic Development Of Mayfly (Hexagenia Limbata) Eggs, Roger Flattum
Journal of the Minnesota Academy of Science
Hunt (19 5 3) states that temperature is an important factor influencing the rate of embryonic development of Hexagenia (mayfly) eggs. Pasvogel (1962) has reported that 46 days is the time limit Hexagenia eggs can remain dormant at temperatures slightly above freezing. It was the object of this investigation to continue this line of research and to determine the effects of temperature on the embryonic development of Hexagenia limbata eggs.
