The study is made in the frame of a follow-up monitoring of all landfill sites in Wallonia, initiated by the Ministry of Environment and managed by ISSeP. The present report concerns a second campaign on the landfill site "Cour-au-Bois" at Braine-le-Château. The usual field inspection technique was applied together with a GC-MS analysis aiming at determining the chemical composition of the ambiant air around the tipping area. [less ▲]

It is often argued that implicit taxation on continued activity of elderly workers is responsible for the widely observed trend towards early retirement. In a world of laissez-faire or of first-best efficiency, there would be no such implicit taxation. The point of this paper is that, when first-best redistributive instruments are not available, because some variables are not observable, the optimal policy does imply a distortion of the retirement decision. Consequently, the inducement of early retirement may be part of the optimal tax-transfer policy. We consider a model in which individuals differ in their productivity and their capacity to work long and choose both their weekly labor supply and their age of retirement. We characterize the optimal non-linear tax-transfer that maximizes a utilitarian welfare function when weekly earnings and the length of active life are observable while individuals' productivity and health status are not observable.

The Brugada syndrome, a genetically transmitted disease according to an autosomal mode with a variable penetrance, is responsible for sudden death secondary to polymorphic ventricular tachycardia. The diagnosis is based on a typical electrocardiographical paturn that combines a right bundle branch block with ST elevation in the right precordial leads. In high risk patients, the automatic implantable defibrillator has the unique capability to protect against the occurrence of ventricular arrhythmias. [less ▲]

The knowledge of the anatomy of the atria and interatrial septum permits different routes to approach the left atrioventricular valve. The Waterston's or Sondegaard's groove approach is the most frequently used, but other approaches such as Dubost'transseptal technique, vertical transseptal approach (Berreklouw-Guiraudon), biatrial inferior transseptal approach (Couetil) or Saksena's approach may be relevant in special situations. It is the purpose of this article to review the anatomic and technical basis of these different approaches and their respective merits. [less ▲]

Defect detection on fruits by machine vision is a complex task. Indeed, the sound tissue colour is not uniform and the defects present a wide variability in colour, shape and texture. Mostly often, images are acquired by conventional RGB cameras and defect segmentation is performed by algorithms based on Bayes'rules. The efficiency of these methods can be improved firstly by acquiring images with a dedicated vision system (multi-spectal imager) and secondly by implementing unsupervised segmentation methods (based on the 'mean shift' procedure; Comaniciu and Meer, 2002).

SPIRIVA (tiotropium) is a long-acting anticholinergic bronchodilatator, inhaled once a day, which produces relaxation of airway smooth muscle through antagonism of acetylcholine at M3-muscarinic receptors. Its duration of action is at least 24h with once daily administration of tiotropium. Several studies have shown its efficacy and its good tolerance in the treatment of patients who are suffering from moderate to very severe chronic obstructive pulmonary disease (COPD). SPIRIVA improves spirometric measurements and quality of life, and reduces dyspnea and exacerbation rate in COPD patients. [less ▲]
