The authors studied the interaction between rider and horse by measuring their ensemble motions in a trot sequence, comparing 1 expert and 1 novice rider. Whereas the novice's movements displayed transient departures from phase synchrony, the expert's motions were continuously phase-matched with those of the horse. The tight ensemble synchrony between the expert and the horse was accompanied by...

A 400-kg 5-year-old Arabian gelding was presented for a 2to 3-year history of progressive uncontrollable violent headshaking that precluded any type of physical activity and compromised quality of life. Although there were no triggering events for the observed behavior, headshaking was exacerbated when a bridle was placed on the horse’s head. One year before presentation, the horse underwent an...

Ferritin was isolated from the fungus Phycomyces blakesleeanus and compared biochemically and immunologically with horse spleen ferritin. Phycomyces and horse spleen ferritins were shown to exhibit similar electrophoretic patterns on polyacrylamide gels. Both preparations yielded an identical single band on sodium dodecyl sulfate-containing polyacrylamide gels. Tryptic digests of Phycomyces fer...

A dust aerosol model was developed and its performance validated against pre-INDOEX measurements. This model was incorporated in the NCMRWF T80 global model. A five-day integration was performed with the assumption that light mineral dust is present over Arabian Sea. Mean shortwave dust forcings were computed from the forecast. In general, at surface, a negative dust forcing was noted. At the t...

Ants of the genus Solenopsis Westwood in the Arabian Peninsula are revised. Six species are treated: Solenopsis elhawagryi Sharaf & Aldawood sp. n., S. geminata (Fabricius, 1804), S. omana Collingwood & Agosti, 1996, S. saudiensis Sharaf & Aldawood, 2011, S. sumara Collingwood & Agosti, 1996, and S. zingibara Collingwood & Agosti, 1996. Solenopsis elhawagryi is described from Beljorashi Governo...

Sediment samples were collected at low tide from various localities of Jubail Marine Wildlife Sanctuary in the Arabian Gulf during 1996-1997 for the study of the marine interstitial ciliate fauna of the Sanctuary. Eleven species belonging to the genus Frontonia (Order: Hymenostomatida) were identified, 7 of which represent new records of the fauna of the Arabian Gulf and of Saudi Arabia. The di...
