The effects of various cholinergic agonists and antagonists and their interactions were determined on the awake-sleep cycle of cats with chronic indwelling brain electrodes. The effects were measured by the use of the EEG and correlated with gross behavioral observation. EEG recordinxs were taken from various neocortical and limbic structures, ~cluding the amygdala and hi~pocampus. EEG activati...

Trypanosoma (Megatrypanum) melophagium is a parasite of sheep transmitted by sheep keds, the sheep-restricted ectoparasite Melophagus ovinus (Diptera: Hippoboscidae). Sheep keds were 100% prevalent in sheep from five organic farms in Croatia, Southeastern Europe, whereas trypanosomes morphologically compatible with T. melophagium were 86% prevalent in the guts of the sheep keds. Multilocus phyl...

Field spinal immobilization using a backboard and cervical collar has been standard practice for patients with suspected spine injury since the 1960s. The backboard has been a component of field spinal immobilization despite lack of efficacy evidence. While the backboard is a useful spinal protection tool during extrication, use of backboards is not without risk, as they have been shown to caus...

Bej§ovec, J.: Permanent Transmission of Endoparasites in Large Herds of Cattle. Acta vet. Bmo,60, 1991: 205-212. Calving houses were found to be cohtaminated with endoparasites by the first crop of pregnant cows arriving in the new premises. No significant differences were found in the incidence of endoparasite species between new and old calving houses by' artalysis of variance. The proportion...

ity in the Glassboro, NJ area (Fig. 1). The Darcian method was used to estimate groundwater recharge Point estimates of groundwater recharge at 48 sediment-coring from water-retention parameters and unsaturated hylocations vary substantially ( 18.5–1840 cm yr 1) in a 930-km2 area of southern New Jersey. Darcian estimates of steady, long-term recharge draulic conductivity on the basis of sedimen...

Since 2005, labour productivity growth in Ontario’s business sector has been zero, greatly under-performing the rest of Canada and being single-handedly responsible for most of what has been described as “Canada’s dismal productivity growth.” This article examines the issue through detailed sectoral data, and finds a wide range of variation underlying the average productivity growth rate. Some ...
