چکیده
analysis. The object of the study was to identify factors influencing outcome. Special attention was paid to those children with medulloblastoma. The average age was 6,7 years for the whole series (range 6 weeks to 15 years). In comparison to national series astrocytomas are over-represented (46.2%) and ependymomas (8.5%) under-represented. However the American Surveillance Epidemiological Evaluation Results registry (S.E.E.R.) has astrocytomas at 44% and ependymomas at 9%, similar proportions to those in the South-West.

Xylem sap flux density (Fd) was measured, on a 43-year-old (mature) and three 4-year-old (young) mango (Mangifera indica L.) trees, using Granier-type probes. The relative influences of environmental variables were examined under well-watered condition.
