Floating boom performance under waves and currents.

Floating booms constitute a fundamental tool for the protection of marine and coastal ecosystems against accidental oil spills. Their containment performances in exposed areas are often impaired by the action of waves, currents and winds in a manner which is dependent on the boom's response as a floating body, and which is not fully understood at present. In this work the relationship between the design parameters of a floating boom section and its efficiency against the mode of failure by drainage under a variety of wave and current combinations is investigated by means of physical modelling.

Benefits of recombinant activated factor VII in complicated liver transplantation.

Introduction: Recombinant activated factor VII (rFVIIa, NovoSeven, NovoNordiskA/S, Bagsvaerd, Denmark) has shown benefits in hemophilic patients and recently in transplant recipients. This study presents our experiences with rFVIIa in complicated liver transplant recipients.

Methods: From May 2001 to August 2004, rFVIIa was administered to 7 patients undergoing liver transplantation.

Villous adenoma of the appendix. Diagnostic and therapeutic approach.

Unlabelled: Appendix villous adenoma is a rare pathological entity that shows a particular form of clinical presentation that is different from villous adenomas in other places along the gastrointestinal tract.

Patients And Methods: We reviewed cases of appendix villous adenoma diagnosed in our hospital during the last five years; we studied age, distribution, sex, clinical presentation, diagnostic methods used, treatment and follow-up of patients.

Results: We diagnosed 6 cases of villous adenoma of the appendix, acute appendicitis being the most common form of clinical presentation.
