We found that the clinical attack rate in 1889 was relatively high and constant between the ages of 1 and 60 years, but was lower outside of the extremes of this age range. By contrast, age-speci...

Ernest P. Manly, W7LHL PO Box 1307 Graham, WA 98338-1307 [email protected] The selection of propagation modes for amateur microwave stations is often progressive. Most of us start with simple equipment and the contacts are usually by line-of-sight propagation. Longer distances are then accomplished by going to high locations. As equipment gets better, the use of various objects for reflection...

The suprachiasmatic nucleus (SCN) of the anterior hypothalamus (AH) is a circadian oscillator and an important component of the mammalian circadian system. To determine whether the SCN is the dominant circadian pacemaker responsible for generating a species-typical characteristic of circadian rhythms [i.e., period length (tau)], neural transplantation was conducted using fetal AH donors of diff...
