Josep Comas Solà, a Catalan astronomer, discovered the periodic comet 32P in 1926, this is why its called 32P/Comas Solà. Since then in its successive returns to the Sun it was observed before and after perihelion passage and its orbit calculated. We present a study of these results to explain the history and the evolution of this comet.

Investigation of the Role of Organic Acids on the Phosphorus and Zinc Uptake by Corn in Calcareous Soils by Using 32P and 65Zn Radioisotopes [PDF]
To investigate the effect of oxalic and citric organic acids on the uptake of Phosphorus and Zinc by corn (Zea mays L.), an experiment was conducted by the use of radioactive potassium phosphate and zinc sulfate fertilizers in microcosm and greenhouse ...

Cinética do fósforo em tecidos de cordeiros recebendo dietas com concentrações crescentes do mineral
Avaliou-se o efeito do incremento na ingestão de fósforo sobre a cinética do mineral nos tecidos de cordeiros. Vinte e quatro cordeiros machos da raça Santa Inês com peso vivo médio de 34,5kg foram distribuídos em quatro tratamentos (0,16; 0,37; 0,58 e 0,

A biosynthetic method for the preparation of high specific activity 32P-labeled phospholipids
32P-Labeled phospholipids with specific activities up to 400 mCi/mmole as well as [32P]CDP-choline were prepared by cultivation of mouse fibroblasts or mouse Ehrlich ascites cells in the presence of [32P]orthophosphate.

Phosphorus utilization by corn as affected by green manure, nitrogen and phosphorus fertilizers
The objective of this work was to evaluate the utilization by corn plants of P from triple superphosphate fertilizer labeled with 32P (32P‑TSP), and of P from soil as affected by N rates and by the green manures (GM) sunn hemp (Crotalaria juncea) and ...
