The members of a beaver family studied under natural conditions in SW Alberta, Canada (115 °03′ W, 51 °02′ N) displayed a free-running circadian rhythm of activity with a period length of about 27 hours in winter, at a time when they were living under ice and had no access to land (Fig. 1, A and C). In summer, the period length of their activity rhythm was(More)
Seventeen red squirrels (Tamiasciurus hudsonicus) were displaced and released about 600 or 2000 m from their home site, and the routes they followed during several hours after release were recorded. The analysis of these routes shows that, in their first attempts to leave the release site area, the squirrels' orientation is non-random with respect to the(More)
Deer mice (Peromyscus maniculatus), kept in individual cages under constant dim-light conditions, displayed steady free-running rhythms of activity, the period of which varied between individuals. When two previously isolated mice with different rhythms were placed in a common enclosure, under the same constant light conditions, they soon displayed a mutual(More)
Beavers studied under natural conditions near Québec City, Canada, displayed a yearly cycle of patterns of activity rhythms. In winter, the beaver colonies had a free-running circadian rhythm of period length 26.25 to 28.0 h, with or without relative coordination, depending on available light intensity, which in turn depends on ice and snow cover(More)
We monitored 300 patients who had undergone ambulatory cataract operations. Patients are more and more preferring this type of surgery, which allows them to go home immediately after the operation. We compare ambulatory ECCE and phacoemulsification operations and their complications, advantages and disadvantages. We shall not go into the real cost-saving(More)
We show that there was little difference in the average astigmatism induced in three surgical groups (Extracapsular (EC), Phacoemulsification with and without scleral tunnelization) at the last control. An examination of a second group of patients shows a significant reduction in the time necessary for recovering at least 80% of the final visual function(More)
