BACKGROUND Severe acute respiratory syndrome (SARS) is currently spreading in many countries. This paper proposes a simple approximate mathematical model for public health practitioners to predict the number of SARS cases and deaths.

Since silicon regulates plant physiological and biochemical processes, it was hypothesized that foliar application could contribute to improving the quality of new potatoes. This paper analyzes effect (sodium silicate) on nutritional value sensory Silicon applied at dose 23.25 g Si·ha−1 or 46.50 once leaf development stage (BBCH 14–16) tuber initiation 40–41) twice, stages. Potatoes were harves...
