In order to achieve some consistency in the establishment of groundwater intrinsic vulnerability maps in Europe. a new, approach is proposed by Working Group 1 of the European COST Action 620 on "Vulnerability mapping for the protection of carbonate (karst) aquifers". A general procedure is offered which provides consistency while allowing the required flexibility for application to a continent and under conditions of varying geology, scale, information availability, time, and resources. The proposed methodology is designed to be clearly more physically based than the existing vulnerability-mapping techniques. It takes the specificity of the karstic environments into account without necessarily excluding the applicability to other geological conditions. Combined "core factors" for overlying layers and for concentration of flow, account for the relative protection of groundwater from contamination while taking into account any bypass of the overlying layers. A precipitation factor is distinguished for describing: characteristics of the input of water to the system. Differentiation is made between groundwater resource intrinsic vulnerability Mapping and Source intrinsic vulnerability mapping. For the latter, a factor describing the karst network development is relevant. This short technical note describes a first stop in the work program of Working Group 1 of the COST Action 620. Future steps are now in progress to quantify the approach and to apply it in various European pilot areas. [less ▲]

BACKGROUND AND PURPOSE: The clinical picture of hand atrophy related to a cervical rib or elongated C7 transverse process was well described in the modern literature by Gilliatt and Sumner; in 1970, they reported a series of nine patients whose motor status was stabilized following brachial plexus decompression. We report here seven patients suffering from thoracic outlet syndrome (TOS), who developed hand atrophy, sometimes because of diagnostic delay. METHODS: The patient's charts were analysed retrospectively. RESULTS: The seven patients were all female; the mean age was 43 years. The first complaints were arm pain and paresthesias lasting six months to 5 years. Three patients were treated with C56/C67 discectomy plus disc prosthesis (one patient), ulnar neurolysis at the elbow (the same patient), carpal tunnel release (one patient), and intravenous immunoglobulins (one patient) before TOS diagnosis. Hand atrophy, severe in five patients, was present at presentation. All patients underwent brachial plexus decompression by the anterior (four), posterior (two), or transaxillary (one) approach. This last approach was completed 18 months later by brachial plexus neurolysis via the anterior approach. Postoperatively, motor deficit was improved in two patients and stabilized in five patients. CONCLUSIONS: Physicians' unfamiliarity with TOS diagnosis or their reluctance to accept the diagnosis without electrical confirmation can lead to hand atrophy. Brachial plexus decompression at this stage usually stabilizes the deficit. [less ▲]

The Tonle Sap Lake and its complex tributaries are the main water body and water courses of Cambodia. The catchment area of the lake is generally divided into twelve major sub-basins. The tributaries of the lake have great potential of water resources for agricultural and industrial development. The river networks and existing irrigation projects are not well surveyed. A survey trip was conducted around the lake. The aim of this trip is to understand the river networks and identify main existing irrigation systems in the sub-basins of the Tonle Sap Lake. In this poster, we are mainly focused on the existing irrigation schemes. The schemes are classified into five categories. (1) “Surface runoff collector”: it is formed by a small dike to collect surface runoff from upstream part. The water collected is used as a supplementary water source for rainy season cultivation and for irrigating a small area of dry season cultivation. (2) “Dam reservoir”: a dam is put in place on a river to store the river runoff during the rainy season and the water stored is supplied to a command area in the dry season. (3) “Indirect diversion”: it is characterized by a diversion structure and a storage reservoir. Water is diverted and stored in the reservoir during the rainy season and used for dry season cultivation. (4) “Direct diversion”: characteristic of this type is similar to that of the indirect diversion, except the river water is diverted directly to irrigated area without storing in a reservoir. (5) “Flood storage”: it is generally developed in the floodplain of the Tonle Sap Lake. A ring dike prevents floodwater from entering the reservoir and rainy season rice is grown inside the dike. After harvesting, the gates on the ring dike are opened to receive floodwater. The water is stored inside the dike for cultivating dry season rice outside the dike. This study found that there are only small-scale irrigation schemes developed around/in the Tonle Sap Lake. The water resources of this lake have not been effectively used. [less ▲]

The enzymatic glucose cleavage of palicoside revealed the biosynthetic pathway to akagerine, whereas the conversion of dolichantoside led to a new quaternary heteroyohimbine alkaloid named N(b)-methyl-21-beta-hydroxy-mayumbine. The hypothetical models of reactions occurring after the conversion of both substrates are proposed. Dolichantoside and palicoside, as well as Strychnos mellodora stem bark crude ethanol extract, exhibit significant antimycotic activity against human pathogens in presence of specific glucosidase.

The issue of transport safety is identified as a major goal in the European Union. The mid term objective declared in the European White Paper for Transport aims at halving the number of deaths on the roads by 2010. Low visibility conditions, especially due to fog, increase the risk of major accidents (chain collision) and a number of innovative products are developed by the automotive industry, including equipment manufacturers, in order to increase the level of safety of the cars passengers and drivers. Testing of these products require the simulation or artificial reproduction of adequate low visibility (fog) conditions with good stability and reproductibility characteristics. The main objective of the “FOG” project was to develop a prototype of innovative fog chamber in which the mechanistic production of fog (by high pressure spraying of water) in a chamber was assisted by an efficient control of the indoor climate. This prototype was installed in a new building constructed on the campus of the University of Liège in Arlon (Belgium). The developments of the project also include a number of additional products enhancing the capabilities of the prototype: - an improved fog production spraying device, including an optimized management - a laser-based visibility measurement device - a reduced scale transmissiometer - a combined indoor climate - fog production simulation software All these products were successfully tested in the conclusive part of the project making the prototype fully operational and ready for use by researchers in the field of transport safety as well as industrial products manufacturers. The capability of the testing facility to test the interaction with the driver was also investigated. The paper will present the major developments of the project and the potential future perspectives of the work. [less ▲]

The purpose of this paper is to present the construction and validation of a questionnaire in order to evaluate the specific work difficulties and compensation mechanisms developed by multiple sclerosis patients (MS). At the moment, only few very recent questionnaires (in English) are constructed in order to highlight the link between the patients’ cognitive deficits with their professional situation (Doogan & Playford, 2014; Honan et al., 2012; McFadden et al., 2012). This lack of accurate assessment is detrimental to the patients’ job retention. Our questionnaire was constructed from review of literature and interviews of patients and experts. In order to validate our questionnaire and to test its specificity to MS patients, three groups of participants answered the questionnaire: MS patients, diabetic patients (diabetes is also a chronic illness but without any cognitive deficits contrary to MS) and a control group. We controlled the effect of anxiety and depression and we conducted a factorial analysis that showed the existence of 3 factors: the ergonomic factor (that includes cognitive difficulties and resources and adaptation process), the description of work situation and the social support. The three groups of participants obtained similar results for the work description and the social support while the group of patients with MS obtained a higher score than the other 2 groups for the ergonomic factor. These results suggest that our questionnaire is specific to the MS population and to the difficulties they specifically meet in their work situations. These results highlight new research opportunities and specific ways to increase job retention in MS population. [less ▲]

Continuous-cover forestry has the goal of relying on natural regeneration, and maintaining irregular stand structure and tree species mixture. However, maintaining mixture of species with different shade tolerances appears arduous with such a silvicultural system. Successfully managing irregular and mixed forests, relying on natural processes, requires a strong knowledge of the ecology of natural regeneration. In theory, regeneration dynamics depends upon the amount of transmitted radiation: shade-tolerant species dominate the regeneration under closed canopies whereas less shade-tolerant species dominate the regeneration under partially open canopies. Nevertheless, it explains hardly the difficulties faced by forest managers to maintain the coexistence of species of different shade tolerances. The purpose of this research is to define light requirements of two species with contrasting shade tolerances (Fagus sylvatica L. and Quercus petraea (Matt.) Liebl.) and, next, determining how understory light can be controlled by forest managers. We find that, contrary to our expectations, the shade-tolerant species outgrow the less shade-tolerant species in all light conditions. We next examine the effects of canopy structure and composition on understory light availability with a model of light interception by heterogeneous canopies. Various silvicultural treatments are tested in order to provide favorable understory light conditions for natural regeneration. The results underline that creating favorable understory light conditions for natural regeneration can be achieved with various regeneration treatments. However, the adequate reduction of stand density depends upon the chosen silvicultural strategies. The outcomes of this study highlight that the control of understory light can be insufficient to maintain the coexistence of species of contrasting shade tolerance, and provide guidelines for the management of understory light in heterogeneous forests.
