In hot countries temperature conditions allow the use of various WSP technologies, including floating macrophytes. We studied duckweeds and they have been used for industrial or domestic waste water treatment. However, the vegetable carpet formed on the water surface must be managed in order to maintain a good efficiency. The duckweeds must be harvested regularly. Otherwise when the biomass is getting too large there is some overlap, mortality increases, and dead cells sink and degrade at the bottom creating a new pollution. In addition, a hazardous harvest of the lenses can involve the reduction in the capacity of purification and also support the development of algae. We tried to monitor the biomass and the environmental parameters of the system (luminosity, temperature, pH, nitrogen, phosphorus, alkalinity, COD…) as well. Indeed, the duckweed biomass measurements were carried out by many researchers (Köner and Vermaat, 1998; Caicédo et al., 2000; Rhamani and Sternberg, 1999; Edwards et al., 1992;…) according mainly to two methods, : the measurement of fresh or dry weight. It appears that these two methods present disadvantages especially for rather long experiments. If the last one is more reliable but destructive, the first on the other hand is less destructive but less accurate and not very reproducible. In the present work, we considered numerical image processing by adapted soft wares, namely: ACDsee® and Image Pro-Plus®. The purpose of this study is thus to establish the surface-biomass relationship for a possible comparison of the resulting biomasses by image and weighing [less ▲]

"L'article de Mme Saint-Remy et de G. Rorive constitue une bonne mise au point sur les controverses qui continuent à se développer autour de la place à réserver au monitorage ambulatoire de la pression artérielle (MAPA) dans l'évaluation du patient hypertendu. La variabilité importante universellement admise de la pression artérielle rend le concept du monitorage pendant 24 heures particulièrement attrayant. L'utilité de cette nouvelle approche ne sera cependant définitivement établie que quand les résultats d'études prospectives visant à démontrer la supériorité du MAPA sur la mesure conventionnelle de la pression artérielle seront connus. Deux études sont au minimum actuellement en cours en ce sens : l'étude OVA et l'étude Systeur. En attendant, le manque de valeurs normatives est évidemment un handicap pour l'intérêt de la MAPA dans la pratique journalière et ce d'autant plus que le coût de cette nouvelle méthodologie reste élevé. Dans la revue de la littérature de ce numéro de Blood Pressure Profile, deux publications viennent confirmer ce qui est avancé dans l'article de Mme Saint-Remy. Bianchi et col, observant que la microalbuminurie est plus importante chez les hypertendus en l'absence de chute nocturne de la pression artérielle, argumentent en faveur du rôle de la MAPA dans l'évaluation du pronostic cardio-vasculaire du patient hypertendu. De plus, Mansoor et al, confirmant la meilleure reproductibilité de MAPA par rapport à la mesure conventionnelle de la pression artérielle, concluent également que la MAPA permettra de diminuer le nombre de patients à inclure dans des essais de pharmacologie clinique. Ces résultats, bien qu'encourageant pour les défenseurs du MAPA, ne doivent cependant pas nous faire oublier que la généralisation de l'utilisation de cette nouvelle technique est à l'heure actuelle prématurée" Prof. J.P.

The theory of the delivery chain considers the delivery of goods and services to customers within a specific time interval. Nowadays, organizations are focusing to satisfy their customers’ demands not only to meet the expectations for products quality but also in delivery times through managing delivery chains. Obviously it is desirable that a company has minimum delivery time of goods and services to its customers. Therefore, establishing economic and reliable control charts for monitoring the key characteristics of delivery chain is of great importance especially for managers to improve the whole delivery chains performance. On the other hand, as we shall see in the present paper, the performance of a delivery chain is multivariate in nature because customers do not evaluate a delivery performance with a univariate mindset and also there are usually several production and delivery sites, and variety of different methods of transportation of goods and services. In this paper, we propose a relatively new application of the economic statistical design of the multivariate T2 control chart to monitor the delivery chain performance and it is illustrated through a case study in the TNT express mail in Iran.

Delivery chains are concerned with the delivery of goods and services to customers within a specific time interval; this time constraint is added to the usual consumer demand for product or service quality. In this context, we address the idea of using process control tools to monitor this key variable of delivery time. In applications, there are usually several production and delivery sites and a variety of different ways to transport, treat and provide goods and services; that makes the problem multivariate in nature. We therefore propose to control the process using multivariate T2 control charts economically designed with the addition of statistical constraints, a design method called economic-statistical design. We illustrate the application in general through an illustrative example. [less ▲]

In this review paper, the authors critically analyse the use of a number of depth of anaesthesia monitors in light of the most recent literature and their own clinical experience. There appears to be increasing evidence that anaesthesia depth monitors reduce the incidence of unexpected intraoperative awareness and also that they improve the quality of anaesthesia. Proper use of these monitors necessitates background knowledge about the physiology of the loss of consciousness, the type of variable recorded and processed by the monitoring devices, the factors that might interfere with recording and the limits of use. The information provided by anaesthesia depth monitors is detailed and relationships with clinical practice are established to provide the reader with key features for optimal use of those monitors and correct interpretation of data. Practitioners and patient's knowledge and expectations regarding this matter, as well as the cost-benefit relationship are also discussed. [less ▲]

In February 1999, a poisoning episode broke out in several industrial poultry farms in Belgium. The source of this contamination was found to be a stock of recycled fat that had been delivered by a firm to several compound feed producers, between 19 and 31 January 1999. A very good correlation was observed between dioxins (PCDFs and PCDDs) and PCBs. Consequently a contamination mainly by PCBs was hypothesized. This finding made it possible to detect contaminated animals and animal products by dosage of the PCBs, more specifically by the 7 congeners with numbers 28, 52, 101, 118, 138, 153 and 180. The advantages of the dosage of PCBs compared to dioxins were its rapid test protocol and the fact that a larger number of laboratories could participate. In the cattle sector, 409 herds (0,81 p. cent) were submitted to the risk of feed contamination. The methodology used to detect a PCBs/dioxins contamination in the Belgian cattle population that was not submitted to the risk, is presented. This population is directly or indirectly destined for human consumption. It consisted in the systematic sampling of all calve fattening stations and all lots of exported bovines, and in the random sampling of slaughter cattle. This methodology is compared to the approach described in directive 96/23/CE. [less ▲]

La gestion des cours d’eau est un exercice difficile qui nécessite souvent de conjuguer différents objectifs et contraintes. Pour assurer une gestion de qualité soucieuse du respect de la multifonctionnalité de ces milieux, il apparaît primordial de disposer d’un état des lieux des ressources à un moment donné et surtout de leur évolution au cours du temps de celles-ci. Le monitoring des bandes riveraines doit donc être considéré comme un outil d’aide à la gestion, à la disposition tant des gestionnaires que des décideurs politiques. [less ▲]

For climatic stress detection and monitoring in the Heilongjiang Province, north-eastem China, an indicator on the interannual vegetation state was extracted from the AVHRR Pathfinder image set (1981-2000) and compared to the rainfall variations over the growing season (June to August). The results show that the vegetation status does not closely depend on rainfall variations in this region. Temperatures, which showed a rapid augmentation in the northern high latitudes since the early 1980s, seem to be a more crucial limiting factor for vegetation growth. Rapid land cover change and large natural disasters are also likely to impact the relationship between rainfall and vegetation. [less ▲]
