In this study we show, on 15 wheat varieties, the ability to assay the asparagine content in a complex matrix such as wheat flour by a simple spectrophotometric assay. This method is easier, faster and cheaper than conventional chromatography analysis and allow to discriminate quickly which materials has high or low level of this amino acid. Asparagine is an amino acid present in free form in the food biomass and has the property of reacting with the free sugars during the Maillard reactions that occur during baking at temperatures above 120°C. The Acrylamide resulting from this reaction chain has been identified as reprotoxic, genotoxic and carcinogenic in animals since 1986. The present method allowed us to identify wheat varieties with significantly lower or higher asparagine contents (α=0.05). Therefore, this method can be used to identify wheat varieties or other plants with low asparagine content to use preferentially in products designed for food. [less ▲]

Web-based Geographical Information Systems (GIS) are excellent tools within interdisciplinary and multi-national geoscience projects to exchange and visualize project data. The web-based GIS presented in this paper was designed for the paleolimnological project 'High-resolution CONTINENTal paleoclimate record in Lake Baikal' (CONTINENT) (Lake Baikal, Siberia, Russia) to allow the interactive handling of spatial data. The GIS database combines project data (core positions, sample positions, thematic maps) with auxiliary spatial data sets that were downloaded from freely available data sources on the world wide web. The reliability of the external data was evaluated and suitable new spatial datasets were processed according to the scientific questions of the project. GIS analysis of the data was used to assist studies on sediment provenance in Lake Baikal, or to help answer questions such as whether the visualization of present-day vegetation distribution and pollen distribution supports the conclusions derived from palynological analyses. The refined geodata are returned back to the scientific community by using online data publication portals. Data were made citeable by assigning persistent identifiers (DOI) and were published through the German National Library for Science and Technology (TIB Hannover, Hannover, Germany). [less ▲]

In this paper a typical situation arising in the assembly of printed circuit boards is investigated. The planning problem we face is how to assemble boards of different types using a single line of placement machines. From a practical viewpoint, the multiplicity of board types adds significantly to the complexity of the problem, which is already very hard to solve in the case of a single board type. In addition, relatively few studies deal with the multiple board type case. We propose a solution procedure based on a hierarchical decomposition of the planning problem. An important subproblem in this decomposition is the so-called feeder rack assignment problem. By taking into account as much as possible the individual board type characteristics (as well as the machine characteristics) we heuristically solve this problem. The remaining subproblems are solved using constructive heuristics and local search methods. The solution procedure is tested on real-life instances. It turns out that, in terms of the makespan, we can substantially improve the current solutions. [less ▲]

In January 1999, Belgium encounters an accidental contamination of the food chain, which was named "the Belgian Dioxin Crisis". The aim of the present review is to estimate the impact of this crisis on public health. Currently, it does not really exist any exhaustive epidemiological study. Various scientific studies actually report somewhat conflicting results. As an example, concerning the population living in Wallonia, recorded dioxin levels are not higher than background levels reported for other industrialized countries, despite the 1999 "dioxin crisis". Conversely, based on levels measured in foodstuffs collected by the end of the crisis period, the dioxin body burden of potential consumers would have increased in the range of 40 to 75 %. The real impact of this crisis on consumers' health could thus only be estimated through well structured epidemiological campaigns. [less ▲]

Using lying deadwood or coarse woody debris (CWD) is on the rise among national and local forest inventories. We compared two generally recommended methods for lying deadwood: line intersect sampling and fixed area sampling. We assessed both methods in plots of the regional forest inventory of Wallonia (southern region of Belgium) and we developed bridging functions that converts CWD volume estimates to estimates that would have been obtained with different thresholds.

Future progress in wheat yield will rely on identifying genotypes and management practices better adapted to the fluctuating environment. Nitrogen (N) fertilization is probably the most important practice impacting crop growth. However, the adverse environmental impacts of inappropriate N management (e.g., lixiviation) must be considered in the decision-making process. A formal decisional algorithm was developed to tactically optimize the economic and environmental N fertilization in wheat. Climatic uncertainty analysis was performed using stochastic weather time-series (LARS-WG). Crop growth was simulated using STICS model. Experiments were conducted to support the algorithm recommendations: winter wheat was sown between 2008 and 2014 in a classic loamy soil of the Hesbaye Region, Belgium (temperate climate). Results indicated that, most of the time, the third N fertilization applied at flag-leaf stage by farmers could be reduced. Environmental decision criterion is most of the time the limiting factor in comparison to the revenues expected by farmers. [less ▲]

SESAME was an Integrated Project under the European Union's 6th Framework Programme. The project involved almost four hundred scientists from 59 research institutes in 24 countries, which included almost all countries of the Mediterranean and Black Sea Basins. This level of cooperation and coordination allowed data collection on different aspects of the Mediterranean and Black Sea ecosystems on a scale never before attempted. The project was designed to study the past, present and future environmental changes in the Southern European Seas (SES) ecosystems, as well as the effect of these changes on fundamental goods (tourism, fisheries) and services (mitigation of climate through carbon sequestration and ecosystem stability through conservation of biodiversity) provided by the ecosystems. The project's innovative character was reflected in the close merging of economic and natural sciences to study changes that occurred in the past 50 years and those that may occur in the next 50 years, through connecting ecological models with climatic and socio-economic scenarios.
