This mixed-methods study investigates the effects of student attitudes and behaviours on the outcomes of learning mathematics with computer tools. A computer tool was used to help students develop the mathematical concept of function. In the whole sample (N = 521), student attitudes could account for a 3.4 point difference in test scores between individuals on a 10-point scale. General attitude...

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...

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...

Studies were conducted to assess the elemental composition of blood serum 39 Arabian pure breed stud horses. The correlation between content toxic elements in serum: aluminum (Al), arsenic (As), cadmium (Cd), lead (Pb), tin (Sn), mercury (Hg), essential trace elements: cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), iodine (I), manganese (Mn), selenium (Se), zinc (Zn) and macronutrients: ca...
