The chemical and microbiological properties of Lebanese perennial coastal rivers were studied during the dry season extending from July to September 2004. The results indicate significant levels of pollution in all eight rivers. Although many physical and chemical variables were within WHO guidelines for drinking water, coliform levels were unacceptably high indicating pollution from untreated ...

a r t i c l e i n f o The impact of dredging and dumping on the morphologic stability of the tidal channels is investigated using morphologic field observations for the Westerschelde estuary dating back to 1955. The results are used to verify the theoretical concept presented by Wang and Winterwerp (2001). This concept states that a critical threshold for the amount of sediment dumping exists a...

Background: Bariatric surgery is deemed one of the most effective procedures for the treatment of obesity and it aims at the reduction and maintenance of weight loss in long term, as the control of the related comorbidities. Aim: Quantify the occurrence of alterations of the gastrointestinal tract, suggestive signs of nutritional deficiencies and the use of supplements in a group of women und...

▪ The extension of European Works Councils to central and eastern Europe is a rare attempt to create transnational employee representation covering both lowand high-wage areas. Research carried out in Poland in 2001 provides a quantitative estimate of such enlargement and a qualitative assessment of its effects. The evidence undermines fears of ‘social dumping’ and reveals indirect effects defi...

We describe a case of malignant duodenocolic fistula in which after a radical resection of right hemicolectomy and pancreaticoduodenectomy, the duodenal defect was reconstructed using a conduit of transposed ileum. This technique, not previously described, offers an alternative to 'duodenal patching', which allows only limited duodenal resection, or gastroenterostomy with its attendant side-eff...

Sperm from Drosophila simulans that carry a sex-ratio distorter is preferentially lost from females' sperm-storage organs. This suggests that sperm dumping is a major factor affecting sperm competition in this species, and may have evolved in response to sex-ratio distorters.

Gastroparesis, caused by delayed emptying of the stomach, has been shown to be associated with Nissen fundoplication. However, symptomatic rapid emptying of the stomach is rare after Nissen fundoplication, and its treatment is often challenging. We report 2 patients with dumping-like syndrome post-fundoplication with marked improvement of symptoms after dietary management and medical treatment.
