Performance assessment of a vertical flow constructed wetland treating unsettled combined sewer overflow.

The performance of a vertical flow constructed wetland for combined sewer overflow treatment (CSO CW) has been evaluated. The full-scale site has been monitored for 3 years for major pollutants and for two load events for a range of micropollutants (metals, metalloids and polycyclic aromatic hydrocarbons (PAHs)). Performance were predominantly high (97% for total suspended solids (TSS), 80% for chemical oxygen demand (COD), 72% for NH-N), even if several loads were extremely voluminous, pushing the filter to its limits.

[Supratentorial glioblastoma in adults. Therapeutic results].

This retrospective study concerns 55 adult patients with supratentorial glioblastoma. The tumours were treated by complete or partial surgical excision whenever possible (31 cases), radiotherapy (22 cases) in doses of 60 Gy over 6 to 7 weeks (40 Gy with telecobalt and 20 Gy with superimposed electrons) and multiple chemotherapy (10 cases) with VM26 and CCNU or BCNU. Although the number of patients in some categories was too small for statistical evaluation, the results obtained were in agreement with those found in the literature and indicative of what can be expected.
