    The Kingdom of Belgium which borders on the nations of France, the Netherlands, Luxembourg, and the Federal Republic of Germany, is one of the smallest European countries and is a parliamentary democracy under a constitutional monarch. The branches of its government are the executive (with a king, a prime minister, and a Council of Ministers), the legislative (a bicameral Parliament and various regional and cultural assemblies), and the judicial (a Court of Cassation modelled on the French system). 30% of Belgium's gross national product comes from machinery, iron and steel, coal, textiles, chemicals, and glass. During the 80 year period which preceded WWI, Belgium remained neutral in an era of intra-European wars until German troops overran the country during their attack on France in 1914. Some of the worst battles of that war were fought in Belgium. Again in 1940, Belgium was occupied by the Germans. There was a government-in-exile in London; however the King remained in Belgium during the war. The course of Belgian politics was determined largely by the division of the Belgian people into 2 major language groups--the Dutch speakers and French speakers. Regional and language rivalries are taken into account in all important national decisions. The 3 major political parties representing the main ideological tendencies are the Socialists, the Socialist Christians, and the Liberals. Belgium is one of the most open economies in the world and is a densely populated, highly industrialized country in the midst of a highly industrialized region. An economic austerity program was instituted at the beginning of this decade which included devaluation of the Belgian franc, reduction of government expenditures, a partial price freeze, etc. Improvements have been seen as a result of this program. Although US investment has declined in recent years, total US direct investment is estimated at $5.28 billion and there are 899 US companies currently operating in Belgium. As a

    The experience of the Netherlands in relation with the legalization and practice of euthanasia is better known in Spain than the Belgian experience in this matter. But the historical process of social debate in Belgium has many specific details which should be known by Spanish healthcare professionals, bioethicists, politicians and lawyers. This paper begins with a comparative analysis of both countries: Spain and Belgium and follows with a description of the milestones of the historical process of debating and, finally, passing the Belgian Law on Euthanasia in 2002. The next chapter consists of a description of the main contents of this important Law. The paper continues then with an approach to the epidemiology of the practice of euthanasia in Belgium and finishes with a description of the different positions of the actors of the process. Two positions are described more in depth: the opinion of the specialists in palliative care, and the opinion of the Catholic Church. The paper ends underlining the reason for the incorporation of the Belgian experience on euthanasia to the debate about the possibility of legalizing euthanasia in Spain.

  5. Nuclear power in Belgium

    International Nuclear Information System (INIS)

    In the energy sector Belgium is 90% dependent on imports. This was clearly felt by the electricity generating economy when the share of hydrocarbons in the energy resources used for electricity generation increased to more than 85% in 1973 as a consequence of rising electricity consumption. Although Belgium had been early to start employing nuclear power for peaceful purposes, only little use had initially been made of this possibility. After the first oil price crisis the Belgian electricity utilities turned more attention to nuclear power. To this day, seven nuclear power plants have been started up, and Belgian utilities hold a fifty percent share in a French nuclear power plant, while the French EdF holds fifty percent in one Belgian nuclear generating unit. The Belgian nuclear power plants, which were built mostly by Belgian industries, have an excellent operating record. Their availabilities are considerably above the worldwide average and they contributed some 60% to the electricity production in Belgium in 1985. Thanks to nuclear power, the cumulative percentage shares of heating oil and gas in electricity production were reduced to well over 15%, compared to 1973, thus meeting the objectives of using nuclear power, i.e., to save foreign exchange and become self-sufficient in supplying the country's needs. The use of nuclear power allowed the Belgian utilities to reduce the price per kilowatthour of electricity and, in this way, remain competitive with other countries. The introduction of nuclear power continues to have a stabilizing influence on electricity generating costs. In the light of the forecast future development of consumption it is regarded as probable that another nuclear power plant of 1390 MWe will have to be built and commissioned before the year 2000.

    European common voles (Microtus arvalis), captured in Belgium in 1999, were proven by molecular as well as by serological techniques to be infected with Tula hantavirus (TULV). This is the first evidence for the presence of TULV in this country. No indication of spill-over infections of Puumala virus, known to be highly endemic among bank voles (Clethrionomys glareolus) within the same geographical regions as the trapped TULV-infected common voles, was observed. Together with previous reports on the circulation of TULV in eastern/central Europe, this finding suggests a more wide-spread circulation of this hantavirus serotype throughout the continent.

    The inventory of geological potentialities for the utilization of low enthalpy geothermal energy in Belgium reveals the lower Cretaceous limestone as an interesting reservoir. This formation, karstic and fractured, is very pervious. The geometry, hydrodynamism, chemistry and water temperature of this formation have been determined for 2 different regions: the Hainaut and the ''Campine anversoise''. In the Hainaut, the first stage, namely urban heating is now under progress; the two other stages are greenhouse heating and sludge heating before biomethanisation. A utilization in series has been planned. In the Campine region, the first well of a demonstration doublet has just been drilled. It will be used for building and greenhouse heating. Another shallower reservoir, situated in a porous chalk formation, is also fairly interesting for an energetic application (swimming-pools, heat pumps heating and biomass).

    Devolder, Katrien

    2016-07-01

    In 2011, Frank Van Den Bleeken became the first detainee to request euthanasia under Belgium's Euthanasia Act of 2002. This article investigates whether it would be lawful and morally permissible for a doctor to accede to this request. Though Van Den Bleeken has not been held accountable for the crimes he committed, he has been detained in an ordinary prison, without appropriate psychiatric care, for more than 30 years. It is first established that Van Den Bleeken's euthanasia request plausibly meets the relevant conditions of the Euthanasia Act and that, consequently, a doctor could lawfully fulfill it. Next, it is argued that autonomy-based reasons for euthanizing him outweigh complicity-based reasons against doing so, and that, therefore, it is also morally permissible for a doctor to carry out the euthanasia request.

  14. The Kingdom of Belgium: country profile.

    Inserra, P

    1986-09-01

    Focus in this discussion of Belgium is on: cities and regions, population change, households and families, labor force, consumption, communication and transport, and sources of information. Belgium was created in 1830 as a constitutional monarch and buffer state amidst great European powers. Its constitution creating a parliamentary system of government has served as a model for many emerging democracies. Unemployment dropped from more than 14% in 1984 to just over 12% in the 1st quarter of 1986. Belgium also is experiencing a somewhat improved balance of payments and respectable overall economic growth of around 2.5% through the 1st half of 1986 along with close trading links and minimum customs formalities with Luxembourg and Holland. Yet, wages lag behind inflation after the last government suspended an index system that mandated automatic income adjustments in line with the cost of living. In 1983, for the 1st time since the country's economic boom of the 1960s, purchasing power for the average Belgium declined. About 90% of Belgium's estimated 9,880,000 inhabitants live in cities and towns ranging over a territory of only 30,518 KM. Administratively, the region of Flanders has 5 provinces, Wallonia, 4. Regions are further broken down into arrondissements and communes. Belgium's under replacement level birth rate is expected to decline further, and its proportion of elderly persons in the total population is expected to rise, straining even further an already overburdened system of social security and health care. Belgium's 10-year intercensal population gain (between 1971-81) was the smallest in the country's history. Belgium's total population stood at 9,853,023 on January 1, 1984, a decline of almost 5000 from the preceding year. Belgium's average household size is decreasing due to a larger aged population, an upsurge in divorces and unmarried young couples, and a declining birth rate. About 1/3 of the population works. At mid-1984, the figure stood at 3

    The top ranking objective is to stimulate the amount of 'green' megawatthours produced via biogas in Belgium. On the one side, this SWOT analysis can be used as a strategic planning tool for the regional and federal authorities. On the other hand, its results can help native and foreign suppliers to get a solid view on the biogas market in Belgium. One of the most important strengths is the existence of a lot of academic and practical knowledge about biogas in Belgium. The fact that there are few digesters in operation and that practical exploitation experience is not widespread is a clear weakness. Another bottleneck is the federal structure of Belgium which results in four different Ministers of Energy and three different regional strategies for the support of biogas in Belgium. One of the biggest problems for agriculture is the enormous manure surplus but this is clearly an opportunity for anaerobic digestion (AD). After all, AD is increasingly seen as the first step in a manure processing facility. Threats in this aspect are the public acceptance of these technologies, the instability of the long term policy, and consequently the instability of financial support mechanisms. (orig.)

  18. Euthanasia in Belgium, the Netherlands and Luxembourg.

    Science.gov (United States)

    2013-11-01

    Each of the Benelux countries (Belgium, Luxembourg, Netherlands) has enacted legislation that partially decriminalises euthanasia, defined as an act that intentionally terminates someone's life at their request. In the Netherlands and Luxembourg, but not in Belgium, the legislation partially decriminalised assisted suicide at the same time. In all three countries, euthanasia can only be performed by a doctor, in response to the patient's voluntary and well-considered request, and for patients who have an incurable disease that causes unbearable suffering, without any prospect of relief. In the Netherlands, minors can request euthanasia as of the age of 12 years. In 2011, reported euthanasia accounted for about 1% of deaths in Belgium and 3% in the Netherlands. In 75% of cases, cancer was the disease leading to a request for euthanasia. In the Netherlands, the number of cases of euthanasia reported by doctors in surveys matches the number that is officially declared. In Belgium, it is thought that there are as many unreported as reported cases of euthanasia. Since the enactment of euthanasia legislation, fewer deaths involve the intentional administration of lethal drugs without an explicit request from the patient.

    Please cite this paper as: Devroey et al. (2011) Online monitoring of flu in Belgium. Influenza and Other Respiratory Viruses 5(5), 351–356. Background  The diagnosis and treatment of patients with the A(H1N1) pandemic flu caused some serious burden for general practitioners (GPs) in the summer and autumn of 2009. Objective  The aim of this study was to track the incidence of influenza and influenza‐like illness (ILI) in Belgium and to describe the characteristics of the affected patients. Methods  In July 2009, the Belgian online influenza surveillance system (BOISS) was set up to monitor the spread of influenza and ILI. Registrations were made by 93 GPs from all 10 Belgian provinces who participated at least 1 week during the first 12 months of the registration. Only patients who met the WHO criteria for flu were recorded. Results  In total, 1254 patients (53% men) with influenza or ILI were included. Mainly younger persons were affected: 43% was under the age of 20 years. A risk factor for influenza‐related complications was determined in 19% of cases, mainly patients with chronic respiratory problems. A treatment with oseltamivir or zanamivir was prescribed in 13%, and 3% of the patients was admitted to a hospital. The time of the peak incidence (44th week) and the magnitude (623 cases per week per 100 000 inhabitants) corresponded with the figures of the existing paper‐based registration network. The small sample size and possible reporting biases may have influenced the findings of the study. Conclusions  The BOISS provides a good alternative to conduct surveillance activities for influenza and ILI in Belgium. It provides complementary information regarding ILI compared to the existing data capturing. PMID:21668686

    Full Text Available This paper examines some results of a research on female offenders’ life histories and pathways to prison in Belgium. Women’s pathways into crime will be presented and the connection of these pathways to their life histories will be explored. The study reveals that the greater part of the research population are adult-onset offenders. The authors argue that the importance of adult-onset pathways for female offenders might be explained by the emergence of (gendered vulnerabilities within the women’s lives, often accumulated not before adulthood.

    This article presents the results of the first survey conducted in Belgium about the interest and knowledge in astronomy. Two samples were studied, the public at large (667 questionnaires) and students (2589 questionnaires), but the results are generally similar in both samples. We evaluated people's interest, main information source, and attitudes towards astronomy, as well as their supposed and actual knowledge of the subject. The main conclusion is that, despite a poor self-confidence, people do know the basic astronomical concepts. However, that knowledge is not deeply rooted, as reasoning questions show well-spread misconceptions and/or misunderstandings.

  10. Spatial dependences among precipitation maxima over Belgium

    Vannitsem, S.; Naveau, P.

    2007-09-01

    For a wide range of applications in hydrology, the probability distribution of precipitation maxima represents a fundamental quantity to build dykes, propose flood planning policies, or more generally, to mitigate the impact of precipitation extremes. Classical Extreme Value Theory (EVT) has been applied in this context by usually assuming that precipitation maxima can be considered as Independent and Identically Distributed (IID) events, which approximately follow a Generalized Extreme Value distribution (GEV) at each recording site. In practice, weather stations records can not be considered as independent in space. Assessing the spatial dependences among precipitation maxima provided by two Belgium measurement networks is the main goal of this work. The pairwise dependences are estimated by a variogram of order one, also called madogram, that is specially tailored to be in compliance with spatial EVT and to capture EVT bivariate structures. Our analysis of Belgium precipitation maxima indicates that the degree of dependence varies greatly according to three factors: the distance between two stations, the season (summer or winter) and the precipitation accumulation duration (hourly, daily, monthly, etc.). Increasing the duration (from one hour to 20 days) strengthens the spatial dependence. The full independence is reached after about 50 km (100 km) for summer (winter) for a duration of one hour, while for long durations only after a few hundred kilometers. In addition this dependence is always larger in winter than in summer whatever is the duration. An explanation of these properties in terms of the dynamical processes dominating during the two seasons is advanced.

  15. Feminism and the health movement in Belgium.

    1984-04-01

    Feminism in Belgium is characterized by its openness and its flexibility. The feminist movement is characterized by; 1) the existence of groups which think about the theory of feminism, encompassing the entire sphere of action of women and concerning itself with private matters and politics; and 2) the existence of action groups which specialize in certain areas. Health has become a matter of great concern for these groups, and one reason for this is the urgent need to put a stop to the scandal of illicit abortion, and the family planning situation in Belgium. It was not until 1973 that information on contraceptive use was permitted. Illicit abortions are still performed, and only women from well-to-do backgrounds have access to "tourist abortion" and can have abortions in England and Holland. The legislative text states that abortion remains an offense against the family and until 1983 the law only allowed certain therapeutic abortions. The women who join the feminist movement are usually professional middle-class women and those of the left and extreme left. These women helped to establish the Groupe d'Action des Centres Extra-Hospitaliers Praiquant des Avortements, an organization of non-hosppital centers that provide abortion services and which provide women with full information on contraception, emphasizing that the decision must be made by the woman herself. Good medial and psychological conditions are provided as well as postabortion care. At present there are 15 centers in Brussels and Wallonia and 2 Flemish centers have recently opened. The centers use a system of payment by the hour or on the basis of fixed fees. The feminist movement has also helped to open up the medical profession to women, opened up hospital services sensitive to feminist ideas, and fought resistence to change among the medical hierarchy, that remains predominantly male.

  16. Nuclear energy policy in Belgium after Fukushima

    International Nuclear Information System (INIS)

    The Belgian nuclear phase-out law imposes closing down in the 2015–2025 period seven nuclear power plants (NPPs) producing more than 50% of the domestic electricity. This creates an urgent problem in the country because of the absence of well-defined capacity-replacement plans. Though a safety-of-supply provision in the law allows for a delayed phase-out, hopes for a technically acceptable schedule have reduced after the Fukushima nuclear disaster in March 2011. In this article policy investigations are made with system dynamics. A significant finding from such modelling is that, in contrast to common expectations, a too early nuclear phase-out will not serve the deployment of renewable energy sources and rational use of energy. It is indeed found to primarily benefit to fossil fuel, creating unwanted drawbacks regarding safety of supply, dependency on foreign suppliers, price volatility, and increased use of non-renewable and CO2-emitting fossil fuels. - Highlights: • Belgium decided to close nuclear plants between 2015 and 2025 to promote renewables. • Hopes for a technically acceptable schedule reduced after the Fukushima disaster. • The Belgian electricity system has been modelled with system dynamics (SD). • SD shows that nuclear plants will be mainly replaced by fossil-fuel plants. • SD shows that it is better for renewables to delay shutdowns or to replace plants

  17. Disposal of disused sealed sources in Belgium

    International Nuclear Information System (INIS)

    It is not foreseen by the Belgian operator to dispose radioactive sealed sources in Near Surface Disposal Facility. The adaptation of the generic safety assessment in order to take in account the presence of sealed sources has been made. The level of concern in the context of the long term safety of a near surface disposal is assessed. On the base of the Belgium exemption level and the extrapolation for the disused sources the range of values above which sources could be considered as to have a significant radiological impact is determined. The number of significant medical sources after 300 years is estimated to be 294. For long term safety after 300 years it is obtained the reduction by a factor 10 of the number of sources, when only three radionuclides 241Am, 137Cs and 226Ra should be taken into account for the long term safety (only α and γemitters). The Belgian Near Surface Disposal Concept is presented. Long Term Safety Assessment including assumptions, generic concept, classification, scenarios (Human intrusion scenario) is presented. It is concluded that high actives of long-lived radionuclides sources should be avoided in a near surface disposal facility regarding the human intrusion scenario. If sources are still foreseen, activity limits should be specified together with requirements on their management. Specific limits could be derived from safety or security scenario. Attempts to distribute other sources in each module of the disposal and to set out the monoliths containing sources away from the intruder possible access could be made. Stylised human intrusion scenarios including sources should be developed by discussions with the safety authority. Scenario addressing the Operational phase should include the presence of sources

    Pressure to control pharmaceutical expenditure and price competition among pharmaceutical companies are fuelling the development of generic drug markets in EU countries. However, in Belgium, the market for generic drugs is underdeveloped compared with other countries. To promote the use of generic drugs, the government introduced a reference pricing (RP) scheme in 2001. The aim of this paper is to discuss Belgian pharmaceutical policy regarding generic drugs and to analyse how the Belgian drug market has evolved following initiation of the RP scheme. The market share held by generic drugs increased following implementation of the RP scheme. Focusing on volume, average market share (by semester) for generic drugs amounted to 2.05% of the total pharmaceutical market from January 1998 to June 2001, compared with 6.11% from July 2001 to December 2003. As new generic drugs are introduced, their market share tends to increase in the first couple of months, after which it levels off. Faced with increasing generic competition, some manufacturers have launched new variants of their original drug, thereby effectively extending the period of patent protection. Strategies consisting of price reductions in return for the abolition of prescribing conditions and the launch of new dosages or formulations appear to have been successful in maintaining the market share of original drugs. Nevertheless, the introduction of the RP scheme was associated with savings amounting to 1.8% of pharmaceutical expenditure by the third-party payer in 2001 and 2.1% in 2002. The findings of this paper indicate that the RP scheme has stimulated the Belgian generic drug market. However, existing policy has largely failed to take into account the role that physicians and pharmacists can play in stimulating generic drug use. Therefore, further development of the Belgian generic drug market seems to hinge on the creation of appropriate incentives for physicians to prescribe, and for pharmacists to

    Take-all of wheat caused by the soil-borne fungus Gaeumannomyces graminis var. Tritici (Ggt) is known world-wide as a major yield-limiting factor. In Belgium, the Take-all disease is not very well known. A take-all survey has been set up in 1999 in Belgium in collaboration between the Agricultural University of Gembloux and Monsanto where goals were to quantify the disease in the main cereal areas and to study the main factors influencing take-all development.

    Most information about the systematics and bioecology of Belgian mosquitoes dates back from before 1950, and only scattered information was produced during the last decades. In this paper we review and update the list of mosquito species recorded in Belgium, from first report (1908) to 2015. Six genera and 31 species were recorded so far, including 28 autochthonous species and three invasive alien species recently recorded in Belgium: Aedes albopictus (Skuse 1894), Ae. japonicus japonicus (Theobald 1901), and Ae. koreicus (Edwards 1917). The six genera are Anopheles (five species), Aedes (sixteen species), Coquillettidia (one species), Culex (four species), Culiseta (four species), and Orthopodomyia (one species).

    Belgium continues to make measured progress in its energy policy, particularly with respect to electricity market liberalisation. The country has improved the independent functioning of the electricity market. An electricity exchange will begin operation shortly. However, to enable Belgian customers to fully benefit from energy market liberalisation, more work needs to be done. In 2003, Belgium decided to phase out nuclear power between 2015 and 2025. As nuclear energy supplies about 55% of the country's electricity, this will be a significant challenge. The federal government should conduct more comprehensive long-term studies on the nuclear energy phase-out and its effects on energy security, environmental protection and economic growth. Belgium's natural gas and electricity markets are highly concentrated. Companies owned by the international power group Suez SA dominate at all levels. Belgium has made some efforts to unbundle these industries and reduce their market dominance, but much more must be done to encourage new entry, increase competition and bring real economic benefits to Belgian customers. 50 refs., 40 tabs., 3 annexes.

    2016-06-01

    Following considerable debate, the practice of euthanasia was legalized in Belgium in 2002, thereby making Belgium one of the few places in the world where this practice is legal. In 2014 the law was amended for the first time. The 2014 amendment makes euthanasia legally possible for all minors who repeatedly and voluntarily request euthanasia and who are judged to possess "capacity of discernment" (regardless of their biological age), as well as fulfil a number of other criteria of due care. This extension of the 2002 euthanasia law generated a lot of national and international debate and has been applauded by many and heavily criticized by others. This evolution is clearly of interest to end-of-life debates in the entire world. This paper will therefore describe how this amendment came to get passed using official documents from Belgium's Senate and Chamber of Representatives where this amendment was discussed and subsequently passed. Next, some of the most commonly given arguments in favour of the law are identified, as well as the arguments most often voiced against the amendment. All these arguments will be expanded upon and it will be examined whether they hold up to ethical scrutiny. Analysing the official documents and identifying the most commonly voiced arguments gives valuable insight into how Belgium came to amend its euthanasia law and why it did so in 2014. It also becomes clear that although the current amendment is often seen as far-reaching, more radical ideas were proposed during the drafting of the law. Also, in analysing those arguments in favour of the amendment and those against, it is clear that the validity of some of these is questionable.

    2016-01-01

    Background Recent cross-cultural comparisons between Asian and Western cultures have shown that ageism arises more from the lack of availability of social and economic resources for older adults than from the culture itself. We tested this assumption by conducting a survey among people living in a least developed country compared with those living in a developed country. Participants and methods Twenty-seven Belgians living in Belgium, 29 Burundians living in Belgium, and 32 Burundians living in Burundi were included in this study. Their attitudes toward older adults were assessed using several self-reported measures. Results Statistical analyses confirmed that older people are more negatively perceived by Burundians living in Burundi than by Burundians and Belgians living in Belgium, whose attitudes did not differ from each other. Conclusion Consistent with our hypothesis, our results suggest that the level of development of a country and more particularly the lack of government spending on older people (pension and health care systems) may contribute to their younger counterparts perceiving them more negatively.

    From the 7th July, 2010 until 14th July, 2010, a heat wave dominated the weather in Belgium. Three major storm situations occurred during this period and all three caused severe damage. In this paper, we discuss the last storm case of 14th July. That day, a quasi-linear convective system (QLCS) crossed parts of France, Belgium and the Netherlands and caused very important wind damages and at least 2 people were killed. Most of the damage was caused by straight-line wind but at least one tornado was observed over the north of the Netherlands. This complex was induced in a very favorable synoptic configuration for severe weather and also the timing of the storm was favorable. In the frame of the Supercell project at the RMI, a damage survey was made of one of the most affected regions, which yielded useful information about the origin of the losses. Careful examination of the radar imagery revealed some connections between internal mesovortices and tracks of enhanced damage. As far as known, this paper is the first description of a derecho in Belgium. It is also the first time a connection is shown between some mesovortices and several damage tracks over the country. During the evolution of the QLCS, several examples of successive vortices were found in front of the system. Several of the vortices were accompanied by a tornado or a funnel cloud and the damage was typically concentrated along elongated tracks.

    Excessive alcohol intake is one of the leading causes of premature death in Europe and particularly in Belgium. Belgian people are consuming more alcohol per year than the European average. It is well established that excessive alcohol consumption is a significant predictor of the development of hypertension (HTN). Two million adults in Belgium suffer from HTN and this number will increase to three million by 2025. Less than 50% of Belgian people treated for HTN are well-controlled. Alcohol reduction in patients with HTN can significantly lower systolic and diastolic blood pressure. After reviewing the epidemiology of HTN and alcohol disorders in Belgium, this paper will focus on the rationale for alcohol screening and brief intervention in primary care. It will also describe the barriers to alcohol screening, and what could be the benefits of alcohol screening for our healthcare system. The authors believe that early identification through alcohol screening and brief intervention in general practice can help to improve the management of patients with HTN, to reach the targets of the WHO Global Action Plan, i.e., a 25% relative reduction in the risk of premature mortality from cardiovascular diseases, cancer, diabetes or chronic respiratory diseases. They are also convinced that this would allow achieving major healthcare savings. PMID:26135944

    The main objective of the ongoing project CORDEX.be, "COmbining Regional Downscaling EXpertise in Belgium: CORDEX and Beyond" is to gather existing and ongoing Belgian research activities in the domain of climate modelling to create a coherent scientific basis for future climate services in Belgium. The project regroups eight Belgian Institutes under a single research program of the Belgian Science Policy (BELSPO). The project involves three regional climate models: the ALARO model, the COSMO-CLM model and the MAR model running according to the guidelines of the CORDEX project and at convection permitting resolution on small domains over Belgium. The project creates a framework to address four objectives/challenges. First, this projects aims to contribute to the EURO-CORDEX project. Secondly, RCP simulations are executed at convection-permitting resolutions (3 to 5 km) on small domains. Thirdly, the output of the atmospheric models is used to drive land surface models (the SURFEX model and the Urbclim model) with urban modules, a crop model (REGCROP), a tides and storm model (COHERENS) and the MEGAN-MOHYCAN model that simulates the fluxes emitted by vegetation. Finally, one work package will translate the uncertainty present in the CORDEX database to the high-resolution output of the CORDEX.be project. The organization of the project will be presented and first results will be shown, demonstrating that convection-permitting models can add extra skill to the mesoscale version of the regional climate models, in particular regarding the extreme value statistics and the diurnal cycle.

    Medication adherence in chronic conditions such as asthma, type 2 diabetes, heart failure, HIV and cancer appears to be a frequent problem. However, the literature on adherence in patients who use inhaled corticosteroids (ICS), oral hypoglycemic agents, drugs for heart failure, antiretrovirals or oral chemotherapy, contains little or no relevant data for Belgium. In the context of a Master thesis in Pharmaceutical care at KU Leuven, a quantitative study was performed to determine the prevalence of adherence to chronic medication in Belgium. This retrospective, cross-sectional study used a database containing refill data of a regional pharmacists' association (KLAV). Out of the 603 pharmacies affiliated with this association, all 50 pharmacies where HIV medication was delivered, were selected. Dispensing data from the selected pharmacies were collected from 01/07/2008 to 31/12/2009 for five pathologies, i.e.; asthma, type 2 diabetes, heart failure, HIV and cancer. Adherence (TT) was calculated with the Medication Refill Adherence (MRA) method. In order to determine whether there were associations between age, gender, drug class and adherence, Chi-square tests were used. Compared with the other patients, cancer patients were the most adherent in taking their drugs (median adherence rate = 88%). In addition, this was the only group in which the median adherence rate was above the set limit of 80%. The patients who were prescribed inhaled corticosteroids were the least adherent (median adherence rate = 38%). More than 50% of patients with asthma/COPD, heart failure and diabetes were classified as "under-users". Furthermore, the results showed a significant association within asthma patients between gender and adherence. In asthma, type 2 diabetes, heart failure and HIV patients there was a significant relationship between age and adherence and drug class and adherence. As the current study has some limitations, the results should be handled with caution. Nevertheless

    The I.R.E. decided in 1975 on the construction of an industrial-scale irradiation plant. Construction started in 1977 and the plant was operational in October 1978. Two cobalt-60 irradiators were built. GAMMIR II, having a maximum source strength of 0.5 MCi, allowed the necessary experience in food irradiation technology to be gained generally and especially in plant engineering, safety precautions and the training of operating personnel. In this paper, the technological and economic feasibility of radiation processing in Belgium is discussed in terms of the following: regulatory status, commercial application of food irradiation, reduction of microbial counts in dry ingredients, and elimination of salmonellae.

    How is it that a small country such as Belgium, with its reputation of relative conservatism, has jumped to the forefront of LGBT-friendly nations when it comes to the extension of rights to, and implementation of government policies for, its LGBT population? The analysis offered here focuses on a combination of six causes: the impact of wider secularization processes; the political history and culture of the country; the organization of especially the Flemish LGBT movement and reasons for its political effectiveness; mainstream social trends in national scapegoating hierarchies; the overall media environment; and the window of opportunity opened by the political landslide of 1999.

    Belgium shows one of the highest numbers of patients with terminal renal failure, treated by means of dialysis, compared to other European countries. Transplantation accounts for only one third of the therapeutic modalities in these patients. As the number of new patients, presenting with terminal renal failure, is equally rising, an always growing discrepancy exists between offered kidneys and patients, desperately waiting for these organs. The same holds true for other organs, as heart, pancreas and liver. This study examines the multiple causes that induce this growing discrepancy and points to some solutions and suggestions that can deal with it. PMID:3303774

  3. Cervical cancer screening in Belgium and overscreening of adolescents.

    Van Kerrebroeck, Helena; Makar, Amin

    2016-03-01

    There has been a marked decrease in the incidence of cervical cancer thanks to cytological screening with the Pap smear test. In Belgium, this screening is rather opportunistic. Over 39% of Belgian women between 25 and 64 years of age are never or only rarely screened by cytological tests. Moreover, there is an excess use of Pap smears because of women who rely on their yearly cervical smear and because many Pap smears are obtained from women beyond the target age range of 25 to 64 years. Sexually active adolescents are increasingly being recognized as a population distinct from adult women. They are at a high risk of acquiring the human papillomavirus (HPV), but most infections and cervical intraepithelial lesions caused by HPV are efficiently cleared by the immune system. We present a description of cervical cancer screening in Belgium using the database of the National Health Insurance Institute (RIZIV/INAMI) and the Belgian Health Care Knowledge Centre (KCE). We describe why elimination of Pap testing in the adolescent population reduces costs and harms without increasing cervical cancer rates. Expectant management, education on the risk factors for cervical cancer and HPV persistence, and HPV vaccination are very important in adolescents and young adults. PMID:25812038

  4. Distributional and regional economic impact of energy taxes in Belgium

    International Nuclear Information System (INIS)

    We analyse the macroeconomic and distributional effects of increased oil excises in Belgium by combining a regional Computable General Equilibrium (CGE) model with a microsimulation framework that exploits the rich detail of household-level data. The link between the CGE model and the microlevel is top–down, feeding changes in commodity prices, factor returns and employment by sector into a microsimulation model. The results suggest that policymakers face an equity-efficiency trade-off driven by the choice of revenue recycling options. When the additional revenue is used to raise welfare transfers to households, the reform is beneficial for lower income groups, but output levels decrease in all regions. However, when the energy tax revenue is used to lower distortionary labour taxes, the tax shift is slightly regressive. In this case, national GDP is hardly affected but regional production levels diverge. The impact of the environmental tax reform on income distribution depends strongly on changes in factor prices and welfare payments, whereas sector composition is an important determinant for regional impact variation. - Highlights: • We study the impact of oil excises across regions and households in Belgium. • Lower income groups gain if the revenue is used to raise welfare payments. • If labour taxes are reduced, the reform is only slightly regressive. • The differential impact across households is driven by factor price changes. • Sector composition is a crucial determinant for impact variation across regions

  5. The taxation of diesel cars in Belgium – revisited

    International Nuclear Information System (INIS)

    This paper compares the current taxation of diesel and gasoline cars in Belgium with the guidelines for optimal taxation. We find that diesel cars are still taxed much less than gasoline cars, resulting in a dominant market share for diesel cars in the car stock. If the fuel tax is the main instrument to control for externalities and generate revenues, the diesel excise should be much higher than the excise on gasoline for two reasons: diesel is more polluting than gasoline and more importantly, through the better fuel efficiency, diesel cars contribute less fiscal revenues per mile. - Highlights: ► With a correct tax system the diesel excise should be higher than that on gasoline. ► When this is difficult, the fixed annual charge should be higher for diesel cars. ► The current tax structure for gasoline and diesel cars in Belgium is suboptimal. ► It implies that CO2 emissions are reduced, but in a very cost-inefficient way

    Full Text Available Abstract Introduction Planning human resources for health (HRH is a complex process for policy-makers and, as a result, many countries worldwide swing from surplus to shortage. In-depth case studies can help appraising the challenges encountered and the solutions implemented. This paper has two objectives: to identify the key challenges in HRH planning in Belgium and to formulate recommendations for an effective HRH planning, on the basis of the Belgian case study and lessons drawn from an international benchmarking. Case description In Belgium, a numerus clausus set up in 1997 and effective in 2004, aims to limit the total number of physicians working in the curative sector. The assumption of a positive relationship between physician densities and health care utilization was a major argument in favor of medical supply restrictions. This new regulation did not improve recurrent challenges such as specialty imbalances, with uncovered needs particularly among general practitioners, and geographical maldistribution. New difficulties also emerged. In particular, limiting national training of HRH turned out to be ineffective within the open European workforce market. The lack of integration of policies affecting HRH was noteworthy. We described in the paper what strategies were developed to address those challenges in Belgium and in neighboring countries. Discussion and evaluation Planning the medical workforce involves determining the numbers, mix, and distribution of health providers that will be required at some identified future point in time. To succeed in their task, health policy planners have to take a broader perspective on the healthcare system. Focusing on numbers is too restrictive and adopting innovative policies learned from benchmarking without integration and coordination is unfruitful. Evolving towards a strategic planning is essential to control the effects of the complex factors impacting on human resources. This evolution requires

  7. Plutonium-enriched thermal fuel production experience in Belgium

    International Nuclear Information System (INIS)

    Taking into account the strategic aspects of nuclear energy such as availability and sufficiency of resources and independence of energy supply, most countries planning to use plutonium look mainly to its use in fast reactors. However, by recycling the recovered uranium and plutonium in light water reactors, the saving of the uranium that would otherwise be required could already be higher than 35%. Therefore, until fast reactors are introduced, for macro- or microeconomic reasons, the plutonium recycle option seems to be quite valuable for countries having the plutonium technology. In Belgium, Belgonucleaire has been developing the plutonium technology for more than 20 yr and has operated a mixed oxide fuel fabrication plant since 1973. The past ten years of plant operation have provided for many improvements and relevant new documented experiences establishing a basis for new modifications that will be beneficial to the intrinsic quality, overall safety, and economy of the fuel

    The Belgian law legalizing euthanasia under strict conditions came into effect September 22, 2002. Any physician performing euthanasia has to complete a registration document and to send it within four days to a federal commission whose mission is to verify that the legal conditions were fulfilled. From September 22, 2002 to December 31, 2013, 8.767 documents have been registered and analyzed by this commission. They are described in six reports referred to Parliament. The present paper analyzes the work of this commission and answers the criticisms concerning its quality and its efficiency. The allegations that clandestine euthanasia's escaping any control are performed are also discussed. In conclusion, it appears that the legal obligations concerning the practice of euthanasia in Belgium are fully effective.

    We assessed the impact of a nation-wide ambulatory care complex intervention (the "care trajectory program") on quality of care in Belgium. We used the three-step public health triangulation method described in this paper and data from four different data sources: a national reimbursement database, an electronic patient record-based general practitioner network, the Belgian general practitioner sentinel network, and a new national registry for care trajectory patients. By applying our method and using the available evidence, we identified key findings that have been accepted by experts and stakeholders. We also produced timely recommendations for the decision-making process, four years after the start of the care trajectory program.

  10. Nuclear and health news. iodine 131 Fleurus incident - Belgium

    International Nuclear Information System (INIS)

    On the 25. august 2008, the operator of the institute of radioelements in belgium has informed the federal agency of nuclear control of an abnormal release of iodine 131 by the chimney of the building to environment. This release occurred following a transfer of liquid effluents between tanks. This release lasts several days and the activity released has been estimated to 45 Giga-becquerels. The incident was classified at the level 3 on the INES scale. The production of radioelements was stopped and the consumption of fruits and vegetables from gardens as well as the rainwater was forbidden at five kilometers at the north-east of the installation. On the 30. august analysis were made on grass and milk but no detection of iodine 131 appears. (N.C.)

  11. Uranium series disequilibrium measurements at Mol, Belgium and Whiteshell

    International Nuclear Information System (INIS)

    Measurements of uranium series disequilibrium in groundwaters derived from sand layers above and below the Boom Clay formation in North East Belgium, are analysed in terms of uranium, thorium and radium isotopic geochemistries, water types, and their mixing in the regional groundwater systems. Most sampled waters are mixtures of younger shallow groundwaters from horizons above the Boom Clay lens and older waters from horizons below the lens, at depths greater than 500m. No true old water end-members have been sampled. The longest residence times of the sampled waters are found to be not much in excess of 104y. More detailed modelling is required in conjunction with groundwater hydraulic pressure and flow direction data to establish detailed mixing patterns. In a second parallel study the 228Ra/226Ra activity ratios were measured in large groundwater samples, from the Underground Research Laboratory at Pinawa, Canada. (author)

    Full Text Available Abstract Background the objective of this study was twofold: 1 Describe the use of antipsychotic treatments in ambulatory patients suffering from schizophrenia in Belgium. 2 Evaluate to which extend antipsychotic treatment prescribing patterns are in accordance with published treatment guidelines. Method A cross-sectional survey was carried out in 16 Belgian hospitals selected from a sample of 67 hospitals. The hospitals were equally distributed between the north and south part of the country and were representative of Belgian practice. During 2 months, participating psychiatrists were asked to record the medication use as well as demographic parameters of all consecutive ambulatory patients seen at their consultation or attending a day-hospital. Data concerning 1000 ambulatory patients with schizophrenia or schizoaffective disorder were collected. Results In Belgium, the use of atypical antipsychotics is frequent (69% in ambulatory patients with schizophrenia. In the overall sample, 73% receive only one antipsychotic drug. The majority of patients are treated with drugs of only one antipsychotic drug group, either first- typical (29.8% or second-generation, atypical antipsychotics (53.2%. 15.8% of patients combine different types of antipsychotics. Antipsychotic dosing is adequate for the majority of patients but about one fifth receives a higher than recommended dose as per package inserts. Polypharmacy remains within reasonable limits. The use of concomitant medication varies according the antipsychotic treatment: patients who take second-generation antipsychotics only, receive the least additional drugs. Conclusion Atypical antipsychotics appear to be the first line treatment for schizophrenic psychosis. Psychiatrists working with ambulatory patients are well aware of treatment guidelines and follow them quite adequately.

  13. Identification and characterization of NORM industries in Belgium

    International Nuclear Information System (INIS)

    An overview of the NORM issue in the Belgium industry is given, mainly based on a study on behalf of ONDRAF/NIRAS, the Belgian agency for radioactive waste. The phosphate industry, which was identified as the main source of enhanced natural radioactivity, is mainly located in Flanders, the northern part of Belgium. The five Flemish phosphate plants handled, from 1920 to 2006, 60 Mton of phosphate ore containing 72 TBq of uranium-238 (radium-226) and 3.5 TBq of thorium-232. This resulted in a vast legacy of 500 ha of contaminated sites. In the non-ferro industry high activity-concentrations of the thorium decay series were identified with cassiterite (tin ore). Zircon sands with high uranium concentrations are applied for the production of precision casting molds. Almost every industry with a large turnover of materials has some problems with NORM, because of the selective concentration of certain radionuclides in by-products, residues or product streams. Examples of a blast furnace and a coal-fired power plant are given. In these cases the natural radioactivity is concentrated in blast furnace slag or fly ash, both of which are used as input material in the cement industry. The extraction and purification of ground water was also identified as a potential source for generating NORM sludges. Finally, ample remains from past NORM practices exist. A number of historical sites, including a former mining area of alum shale in the valley of the Meuse, several coal mining sites, a coltan processing site in Ghent and a radium facility in Olen were contaminated before present standards of radiological protection were developed.

    To advance our restricted knowledge on mosquito biodiversity and distribution in Belgium, a national inventory started in 2007 (MODIRISK) based on a random selection of 936 collection points in three main environmental types: urban, rural and natural areas. Additionally, 64 sites were selected because of the risk of importing a vector or pathogen in these sites. Each site was sampled once between May and October 2007 and once in 2008 using Mosquito Magnet Liberty Plus traps. Diversity in pre-defined habitat types was calculated using three indices. The association between species and environmental types was assessed using a correspondence analysis. Twenty-three mosquito species belonging to traditionally recognized genera were found, including 21 indigenous and two exotic species. Highest species diversity (Simpson 0.765) and species richness (20 species) was observed in natural areas, although urban sites scored also well (Simpson 0.476, 16 species). Four clusters could be distinguished based on the correspondence analysis. The first one is related to human modified landscapes (such as urban, rural and industrial sites). A second is composed of species not associated with a specific habitat type, including the now widely distributed Anopheles plumbeus. A third group includes species commonly found in restored natural or bird migration areas, and a fourth cluster is composed of forest species. Outcomes of this study demonstrate the effectiveness of the designed sampling scheme and support the choice of the trap type. Obtained results of this first country-wide inventory of the Culicidae in Belgium may serve as a basis for risk assessment of emerging mosquito-borne diseases.

    Belgium and Bosnia can be understood as 'divided house' states, which contain proportionally similar groups with opposing views regarding whether the states should be more unitary or more decentralized. The Belgian example demonstrates that even where groups disagree on state structure, a mixture of various forms of group autonomy may facilitate stability and compromise within the state. Belgium addresses this dilemma in two ways: 1) non-territorial autonomous unites in the form of linguistic...

    2012-09-01

    The present study aimed to investigate both the on road behaviour of Belgian school students and the validity of the Adolescent Road User Behaviour Questionnaire (ARBQ) in a sample of students attending school in Belgium. In total, 294 adolescents completed the ARBQ along with measures of their self-reported accident involvement and sensation seeking behaviour. Confirmatory Factor Analysis supported the original factor structure of: "unsafe road crossing", "playing on the road" and "planned protective behaviour" for the 21-item version of the questionnaire, but not for the full scale. Males were found to engage more often in unsafe crossing behaviour and playing on the roads. There were also age differences, with unsafe road crossing increasing with age and engagement in planned protective behaviours improving with age. Those who reported being involved in an accident also reported more frequent engagement in unsafe crossing, playing on the roads, thrill seeking behaviour and lower levels of behaviour inhibition. Therefore, this study confirms that the ARBQ is a useful tool for investigating safety-related behaviours that contribute to accident involvement.

    In the frame of a regional project evaluating the geothermal potential of the Wallonian Region of Belgium, the Hockai Fault Zone has been identified as one of the most interesting targets. It is a seismically active fault zone that hosted the largest historical earthquake in Northwestern Europe, the M6-6.5 Verviers event in 1692 as well as a swarm of small earthquakes that was recorded in 1989-90. On the surface, the presence of the fault zones is marked by a series of geomorphic features, such as several landslides near the borders in the northern part, repeated NW-SE oriented scarps all along the Eastern border (over a distance of 40 km), river diversions and captures with formation of paleo-valleys. Along the most prominent paleo-valley, the Paleo-Warche Valley crossing the fault zone over a distance of 5 km, a geophysical survey has been organized by several teams to better characterize the shallow (resistivity tomography as well as ambient noise recordings. To support an integrated interpretation of all geophysical results in combination with geomorphic and seismo-tectonic aspects, surface morphology, soundings and profiles were represented in a 3D model. This model clearly reveals low-resistivity and low-velocity zones near the Eastern border of the fault zone, vertically above the hypocenters of the 1989-90 earthquake swarm. Across the structure, low-resistivity zones have a limited extent while they are repeatedly identified all along Eastern border.

  2. Decommissioning of a section of a discharge line in Belgium

    International Nuclear Information System (INIS)

    As a result of a judicial decision, a licensed discharge line for very low level radioactive liquid wastewater to the river Molse Nete in Belgium had to be removed from the gardens of seven properties within a time schedule of one year. The pipeline was constructed in 1956 by the Belgian Nuclear Research Centre (SCK-CEN) and transferred the wastes a distance of about 10 km from the Belgoprocess Site 2 to the river Molse Nete. It is an asbestos cement pipeline with a wall thickness of 13 mm and an inner diameter of 20 cm. Individual pipe sections have a length of about 5 m and are interconnected by sleeves. The section to be removed was situated on average about 1 m (maximum 1.6 m) below ground level. Access was hampered by the various structures (for example summer houses and garages) that had since been built in the area. A new steel discharge pipe was installed to ensure the continuity of the discharge authorization

    2012-12-15

    In this report, different long-term evolutions of the Belgian future energy system are drafted, analysed and evaluated. All evolutions are designed to meet the requirement of a 100% renewable based national energy system by 2050. For this purpose, a baseline is developed which depicts an energy system without the stringent renewables' requirement. Next, different trajectories are sketched that lead up to a 100% renewable coverage in 2050. The trajectories show that it is feasible to combine economic growth and comfort with far going deployment of renewable energy sources, provided a number of key options and effective policies and measures are being implemented. These options were deducted from several discussions with stakeholders via an open dialogue process, as well as with national experts, and finally, were presented to the Steering committee. The analysis leads to the undeniable observation that drastic changes in a multitude of areas throughout society are required to obtain the desired level of renewable energy penetration in 2050, but also that such a transition can be realised through various sectoral, technology and inter-temporal choices. In other words, this study describes a vast number of different trajectories leading to a 100% renewable energy system in Belgium in the long term, as well as their socio-economic impacts.

  5. Clinical radiotherapy audits in Belgium, 2011-2014.

    Scalliet, P G M

    2015-10-01

    Systematic clinical radiotherapy audits have been introduced in Belgium in 2011, as part of the Federal Cancer Plan. This is in compliance with article 11 of the 97/43 Council directive of Euratom states, translated into the Belgian legislation by royal decree in 2002. The principle of clinical audits has thus been part of the federal legal requirements for more than 10 years. However, its application had to wait for the development of a practical approach: what authority will audit, who will be the auditors, along which methodology, at what frequency, etc. Since 2002, the Federal College of Radiotherapy has the mission to monitor quality of radiotherapy at large. It was therefore decided after discussions with the relevant administration at the Ministry of Health and the Federal Agency for Nuclear Control that the College would practically organise the audits. Early in the 2000s, the IAEA developed a manual for comprehensive audits, as a tool for quality improvement. Auditors were professionals of the domain and the audit visit took the form of a peer review. Great care was taken to assemble an audit party able to cover all aspects of clinical radiotherapy with a radiation oncologist, a medical physicist, a radiation therapist and, on demand, a quality officer. The IAEA manual contains a series of questionnaires to be prepared by the audited centre in advance (pre-audit and self-assessment), indicating what specific areas the auditors would assess. It is also a template for the auditors, ensuring that no area is left aside or forgotten during the site visit. The report, at the end of the visit, is drafted according to a specific report template, also developed by IAEA. Several members of the Belgian radiotherapy community have developed their auditor's skills by participating to the IAEA audit program; they are the core of the auditor Belgian team. PMID:26321683

  6. Recent Photocatalytic Applications for Air Purification in Belgium

    2014-07-01

    Full Text Available Photocatalytic concrete constitutes a promising technique to reduce a number of air contaminants such as NOx and VOC’s, especially at sites with a high level of pollution: highly trafficked canyon streets, road tunnels, the urban environment, etc. Ideally, the photocatalyst, titanium dioxide, is introduced in the top layer of the concrete pavement for best results. In addition, the combination of TiO2 with cement-based products offers some synergistic advantages, as the reaction products can be adsorbed at the surface and subsequently be washed away by rain. A first application has been studied by the Belgian Road Research Center (BRRC on the side roads of a main entrance axis in Antwerp with the installation of 10.000 m² of photocatalytic concrete paving blocks. For now however, the translation of laboratory testing towards results in situ remains critical of demonstrating the effectiveness in large scale applications. Moreover, the durability of the air cleaning characteristic with time remains challenging for application in concrete roads. From this perspective, several new trial applications have been initiated in Belgium in recent years to assess the “real life” behavior, including a field site set up in the Leopold II tunnel of Brussels and the construction of new photocatalytic pavements on industrial zones in the cities of Wijnegem and Lier (province of Antwerp. This paper first gives a short overview of the photocatalytic principle applied in concrete, to continue with some main results of the laboratory research recognizing the important parameters that come into play. In addition, some of the methods and results, obtained for the existing application in Antwerp (2005 and during the implementation of the new realizations in Wijnegem and Lier (2010–2012 and in Brussels (2011–2013, will be presented.

    Biermans, G.; Dehandschutter, B.; Pepin, S.; Sonck, M. [Federal Agency for Nuclear Control - FANC (Belgium)

    2014-07-01

    In the Belgian Royal Decree of 20 July 2001, which transposed the EU Directive 96/26/EURATOM (BSS) into national legislation regarding radiation protection regulations, a list of 'work activities involving natural radiation sources' (i.e. NORM industries) was defined based on the concept described in Article 40 of the Directive. These activities are subject to declaration to the Belgian radiation protection authority (Federal Agency for Nuclear Control - FANC). The initial list was subsequently modified by a FANC decree in 2012 to reflect the increased knowledge about NORM in other industrial sectors, most of which have also been added in the recently published New Basic Safety Standards (Directive 2013/53/EURATOM). In March 2013, an additional decree was published by FANC regulating the acceptance of NORM residues by non-radioactive waste treatment facilities. This regulation was fitted within the framework described above by introducing NORM residue treatment into the existing NORM industry list. It introduces generic exemption levels above which the processing or disposal of NORM residues will be considered as a 'work activity' and submitted to declaration according to the Belgian radiation protection regulations. On basis of this declaration, specific acceptance criteria are assigned to the disposal or processing facility. FANC has published technical and methodological guides for the operators of the concerned facilities and industries to facilitate the declaration process, and has recently organized a round-table gathering both NORM industries and waste processing industries to identify the needs, uncertainties and concerns regarding the regulatory control of NORM in Belgium.

  9. Weather based risks and insurances for crop production in Belgium

    Science.gov (United States)

    Gobin, Anne

    2014-05-01

    Extreme weather events such as late frosts, droughts, heat waves and rain storms can have devastating effects on cropping systems. Damages due to extreme events are strongly dependent on crop type, crop stage, soil type and soil conditions. The perspective of rising risk-exposure is exacerbated further by limited aid received for agricultural damage, an overall reduction of direct income support to farmers and projected intensification of weather extremes with climate change. According to both the agriculture and finance sectors, a risk assessment of extreme weather events and their impact on cropping systems is needed. The impact of extreme weather events particularly during the sensitive periods of the farming calendar requires a modelling approach to capture the mixture of non-linear interactions between the crop, its environment and the occurrence of the meteorological event. The risk of soil moisture deficit increases towards harvesting, such that drought stress occurs in spring and summer. Conversely, waterlogging occurs mostly during early spring and autumn. Risks of temperature stress appear during winter and spring for chilling and during summer for heat. Since crop development is driven by thermal time and photoperiod, the regional crop model REGCROP (Gobin, 2010) enabled to examine the likely frequency, magnitude and impacts of frost, drought, heat stress and waterlogging in relation to the cropping season and crop sensitive stages. The risk profiles were subsequently confronted with yields, yield losses and insurance claims for different crops. Physically based crop models such as REGCROP assist in understanding the links between different factors causing crop damage as demonstrated for cropping systems in Belgium. Extreme weather events have already precipitated contraction of insurance coverage in some markets (e.g. hail insurance), and the process can be expected to continue if the losses or damages from such events increase in the future.

  10. Environmental conditions and Puumala virus transmission in Belgium

    Leirs Herwig

    2007-12-01

    Full Text Available Abstract Background Non-vector-borne zoonoses such as Puumala hantavirus (PUUV can be transmitted directly, by physical contact between infected and susceptible hosts, or indirectly, with the environment as an intermediate. The objective of this study is to better understand the causal link between environmental features and PUUV prevalence in bank vole population in Belgium, and hence with transmission risk to humans. Our hypothesis was that environmental conditions controlling the direct and indirect transmission paths differ, such that the risk of transmission to humans is not only determined by host abundance. We explored the relationship between, on one hand, environmental variables and, on the other hand, host abundance, PUUV prevalence in the host, and human cases of nephropathia epidemica (NE. Statistical analyses were carried out on 17 field sites situated in Belgian broadleaf forests. Results Linear regressions showed that landscape attributes, particularly landscape configuration, influence the abundance of hosts in broadleaf forests. Based on logistic regressions, we show that PUUV prevalence among bank voles is more linked to variables favouring the survival of the virus in the environment, and thus the indirect transmission: low winter temperatures are strongly linked to prevalence among bank voles, and high soil moisture is linked to the number of NE cases among humans. The transmission risk to humans therefore depends on the efficiency of the indirect transmission path. Human risk behaviours, such as the propensity for people to go in forest areas that best support the virus, also influence the number of human cases. Conclusion The transmission risk to humans of non-vector-borne zoonoses such as PUUV depends on a combination of various environmental factors. To understand the complex causal pathways between the environment and disease risk, one should distinguish between environmental factors related to the abundance of hosts

    2009-05-01

    In this article, we examine climate model estimations for the future climate over central Belgium. Our analysis is focused mainly on two variables: potential evapotranspiration (PET) and precipitation. PET is calculated using the Penman equation with parameters appropriately calibrated for Belgium, based on RCM data from the European project PRUDENCE database. Next, we proceed into estimating the model capacity to reproduce the reference climate for PET and precipitation. The same analysis for precipitation is also performed based on GCM data from the IPCC AR4 database. Then, the climate change signal is evaluated over central Belgium using RCM and GCM simulations based on several SRES scenarios. The RCM simulations show a clear shift in the precipitation pattern with an increase during winter and a decrease during summer. However, the inclusion of another set of SRES scenarios from the GCM simulations leads to a less clear climate change signal.

    We report an unusual case in Belgium of indigenous intestinal myiasis caused by Eristalis tenax during canicular summer 2003 in a 36 year old man living in Belgium. This patient complain near its general practitioner about diarrhea and intestinal rumbles. Larvae emitted on several occasions were identified as Eristalis tenax larvae. Socio-economical status of the patient and atmospheric conditions seems to be related to this observation. Clinical evolution has been spontaneously and quickly positive. An empirical treatment with an association of metronidazole and nifuroxazide was however prescribed. PMID:15462515

    In Memory of Ed Pellegrino. Euthanasia in Belgium is not limited to terminally ill patients. It may be applied to patients with chronic degenerative diseases. Currently, people in Belgium wish to make it possible to euthanize incompetent patients who suffer from dementia. This article explains the Belgian law and then explores arguments for and against euthanasia of patients with dementia. It probes the dementia paradox by elucidating Dworkin's distinction between critical and experiential interests, arguing that at the end-of-life this distinction is not clearcut. It argues against euthanasia for patients with dementia, for respecting patients' humanity and for providing them with more care, compassion, and good doctoring.

    2010-05-01

    The proposed Soil Framework Directive COM(2006)232 requires Member States to identify areas at risk of erosion, decline in organic matter, salinisation, compaction, sealing and landslides, as well as to set up an inventory of contaminated sites. The present project aims to identify the susceptibility to compaction of soils of the Walloon Region (Belgium) and to recommend good farming practices avoiding soil compaction as far as possible. Within this scope, the concept of precompression stress (Pc) (Horn and Fleige, 2003) was used. Pc is defined as the maximum major principal stress that a soil horizon can withstand against any applied external vertical stress. If applied stress is higher than Pc, the soil enters in a plastic state, not easily reversible. For a given soil, the intensity of soil compaction is mainly due to the applied load which depends on vehicle characteristics (axle load, tyre dimensions, tyre inflation pressure, and vehicle velocity). To determine soil precompression stress, pedotransfert functions of Lebert and Horn (1991) defined at two water suctions (pF 1.8 and 2.5) were used. Parameters required by these functions were found within several databases (Aardewerk and Digital Map of Walloon Soils) and literature. The validation of Pc was performed by measuring stress-strain relationships using automatic oedometers. Stresses of 15.6, 31, 3, 62.5, 125, 250, 500 and 1000 kPa were applied for 10 min each. In this study, the compaction due to beet harvesters was considered because the axle load can exceed 10 tons and these machines are often used during wet conditions. The compaction at two depth levels was considered: 30 and 50 cm. Compaction of topsoil was not taken into account because, under conventional tillage, the plough depth is lower than 25 cm. Before and after the passage of the machines, following measurements were performed: granulometry, density, soil moisture, pF curve, Atterberg limits, ... The software Soilflex (Keller et al., 2007

    2009-04-01

    Although scientific research on landslides in the Flemish Ardennes (710 km²; Belgium), has been conducted over the last decades, the Flemish Government only took account of slope failure as a soil degradation process after the occurrence of several damaging landslides in the beginning of the 21st century. Here we aim to present the successful collaboration between the Physical and Regional Geography Research Group (FRG; Dept. Earth and Environmental Sciences K.U.Leuven) and the Environment, Nature and Energy Department (LNE; Flemish Government) in landslide management. We will demonstrate how geomorphologists produced practical tools for landslide management which can be directly applied by LNE as well as other local and regional authorities and planners. Since 2004 three projects on landslide inventory mapping and susceptibility assessment in the Flemish Ardennes have been funded by LNE, and a fourth one on landslide susceptibility assessment in remaining hilly regions in Flanders west of Brussels recently started. Together with a steering committee composed of stakeholders, persons from LNE supervise the research carried out by geomorphologists experienced in landslide studies. For the establishment of the landslide inventory map of the Flemish Ardennes we combined the analysis of LIDAR-derived hillshade and contour line maps with detailed field controls. Additional information was collected through interviews with local authorities and inhabitants and from analysis of newspaper articles and technical reports. Then, a statistical model, logistic regression, was applied to produce a high quality classified landslide susceptibility map. The unique part of this collaboration is that all end products are online available at user-friendly websites designed by LNE. The scientific report containing (1) general information on landslides, (2) a description of the study area, (3) an explanation of the materials and methods used, (4) a presentation of the resulting

    Schmallenberg virus (SBV) emerged across Europe in 2011 and Belgium was among the first countries affected. In this study, published findings are combined with new data from veterinary surveillance networks and the Belgian reference laboratory for SBV at the Veterinary and Agrochemical Research centre (CODA-CERVA) to reconstruct the epidemic in Belgium. First retrospective cases of SBV were reported by veterinarians that observed decreased milk yield and fever in dairy cattle in May 2011. The number of SBV suspicions subsequently increased in adult cattle in August 2011. That month, first SBV positive pools of Culicoides were detected and extensive virus circulation occurred in Belgium during late summer and autumn 2011. As a consequence, most pregnant ruminants were infected and their fetuses exposed to the virus. This resulted in an outbreak of abortions, still-births and malformed new-borns observed between January and April 2012. The number of cases drastically diminished in 2012-2013, although multiple lines of evidence obtained from cross-sectional serological surveys, analyses on aborted foetuses, sentinel herd surveillance and surveillance of SBV in vectors prove that SBV was still circulating in Belgium at that time. Virus circulation was then probably strongly reduced in 2013-2014, while increasing evidence indicates its recirculation in 2014-2015 in Belgium. Based on the experience gathered with the closely related Akabane virus, recurrent outbreaks of congenital events can be expected for a long period. Vaccination of seronegative animals before the first mating could be used to prevent the deleterious effects of SBV. During this epidemic, different surveillance approaches including syndromic surveillance, sentinel herd surveillance, cross-sectional seroprevalence studies and pathogen surveillance in vectors have proven their utility and should be considered to continue in the future.

  1. An analysis on energy efficiency initiatives in the building stock of Liege, Belgium

    International Nuclear Information System (INIS)

    Built environment is responsible for 60% of total energy consumption in European countries and 128 million BOE of primary energy in Belgium. The average energy consumption in the residential buildings of Belgium is 70% higher than the EU average and stands at 348 kW h/m2/year. Energy Performance Building Directive (EPBD) provides guidelines for energy performance analysis of buildings in Belgium. In this study, a holistic approach has been adopted to analyse the building stock of Liege, Belgium. This analysis is based on ‘General Socio-economic survey 2001’ and ‘Housing quality survey 2006 in Walloon region’ databases. It considers parameters such as buildings age, built-up area, type of heating system, type of fuel used, adjacency, insulation of roofs and walls and energy consumption etc. for an in depth analysis. This study concludes that about 69% of buildings which are constructed before 1945 needs serious renovation towards the improvement of roof and external wall insulation level. It then successfully identifies specific areas which need detailed study to evaluate the comfort status in the existing building stock, improvement of insulation level and its effect on heating energy consumption as well as the economic analysis on energy efficiency measurements. -- Highlights: •Energy efficiency studies of building stock of Liege, Belgium. •Energy Performance Building Directive is used as reference for analysis. •Buildings age, built-up area and energy consumption data are used for analysis. •Identifies the areas to improve energy efficiency of building stock

    As part of a research project on the food deception strategy in Orchis militaris (L.), the objective of this study was to identify insect visitors and potential pollinators of this orchid species in Belgium. In 2013, insects were collected over 2 d per site in five localities distributed in Southern Belgium (Wallonia). A total of 104 insects belonging to 49 species were caught. Dipterans were the most abundant visitors (50% of total specimens), followed by Hymenopterans (32%). Rhingia campestris Meigen, Bombylius venosus Mikan, Apis mellifera (L.), and Bombus lapidarius (L.) were the most abundant species. Only five specimens bore one to more than 10 pollinia: four honeybees (A. mellifera) and one bumblebee worker (B. lapidarius). These two species should be considered as potential pollinators in the study area, but probably not confirmed ones. PMID:27694346

    Graphite furnace atomic absorption spectrometry, with Zeeman background correction and after improved matrix modification, was used to measure the plasma selenium content of healthy blood bank donors in the central part of Belgium. The mean plasma selenium concentration of 80 men and 80 women was 79.7+/-4.4ng/mL with a range of 55.0-117.4ng/mL. There was no gender difference observed. Plasma selenium level was significantly highest for the adult group, aged 45-64 years, compared to the others, except the young adults (18-24 years). The mean plasma selenium concentration measured corresponded well with literature data for Belgium. The obtained values were found to be in the medium range, compared with recent literature values for the European countries. PMID:17980813

  7. Establishing specialized health services for professional consultation in euthanasia: experiences in the Netherlands and Belgium

    Science.gov (United States)

    2009-01-01

    Background The Netherlands, Belgium, and Luxembourg have adopted laws decriminalizing euthanasia under strict conditions of prudent practice. These laws stipulate, among other things, that the attending physician should consult an independent colleague to judge whether the substantive criteria of due care have been met. In this context initiatives were taken in the Netherlands and Belgium to establish specialized services providing such consultants: Support and Consultation for Euthanasia in the Netherlands (SCEN) and Life End Information Forum (LEIF) in Belgium. The aim of this study is to describe and compare these initiatives. Methods We studied and compared relevant documents concerning the Dutch and Belgian consultation service (e.g. articles of bye-laws, inventories of activities, training books, consultation protocols). Results In both countries, the consultation services are delivered by trained physicians who can be consulted in cases of a request for euthanasia and who offer support and information to attending physicians. The context in which the two organisations were founded, as well as the way they are organised and regulated, is different in each country. By providing information on all end-of-life care matters, the Belgian LEIF seems to have a broader consultation role than the Dutch SCEN. SCEN on the other hand has a longer history, is more regulated and organised on a larger scale and receives more government funding than LEIF. The number of training hours for physicians is equal. However, SCEN-training puts more emphasis on the consultation report, whereas LEIF-training primarily emphasizes the ethical framework of end-of-life decisions. Conclusion In case of a request for euthanasia, in the Netherlands as well as in Belgium similar consultation services by independent qualified physicians have been developed. In countries where legalising physician-assisted death is being contemplated, the development of such a consultation provision could also

In this doctoral thesis, we contribute to this literature by questioning the causes of unemployment persistence in Belgium. To that purpose, we conduct an in-depth econometric analysis of the flows out of unemployment in this country. In Chapters 2 and 3, we study the behaviour of the exit rate out of unemployment over duration ...

    Full Text Available Abstract Background Previous research has provided evidence that socioeconomic status has an impact on invasive treatments use after acute myocardial infarction. In this paper, we compare the socioeconomic inequality in the use of high-technology diagnosis and treatment after acute myocardial infarction between the US, Quebec and Belgium paying special attention to financial incentives and regulations as explanatory factors. Methods We examined hospital-discharge abstracts for all patients older than 65 who were admitted to hospitals during the 1993–1998 period in the US, Quebec and Belgium with a primary diagnosis of acute myocardial infarction. Patients' income data were imputed from the median incomes of their residential area. For each country, we compared the risk-adjusted probability of undergoing each procedure between socioeconomic categories measured by the patient's area median income. Results Our findings indicate that income-related inequality exists in the use of high-technology treatment and diagnosis techniques that is not justified by differences in patients' health characteristics. Those inequalities are largely explained, in the US and Quebec, by inequalities in distances to hospitals with on-site cardiac facilities. However, in both Belgium and the US, inequalities persist among patients admitted to hospitals with on-site cardiac facilities, rejecting the hospital location effect as the single explanation for inequalities. Meanwhile, inequality levels diverge across countries (higher in the US and in Belgium, extremely low in Quebec. Conclusion The findings support the hypothesis that income-related inequality in treatment for AMI exists and is likely to be affected by a country's system of health care.

    This paper explores a newly-available panel data set merging balance sheet and international trade transaction data for Belgium. Both imports and exports appear to be highly concentrated among few firms and seem to have become more so over time. Focusing on manufacturing, we find that facts previously reported in the literature for exports only actually apply to imports too. We note that the number of trading firms diminishes as the number of export destinations or import origins increases. T...

  1. Impact of rotavirus vaccination on hospitalisations in Belgium: comparing model predictions with observed data.

    Directory of Open Access Journals (Sweden)

    Baudouin Standaert

    Full Text Available BACKGROUND: Published economic assessments of rotavirus vaccination typically use modelling, mainly static Markov cohort models with birth cohorts followed up to the age of 5 years. Rotavirus vaccination has now been available for several years in some countries, and data have been collected to evaluate the real-world impact of vaccination on rotavirus hospitalisations. This study compared the economic impact of vaccination between model estimates and observed data on disease-specific hospitalisation reductions in a country for which both modelled and observed datasets exist (Belgium. METHODS: A previously published Markov cohort model estimated the impact of rotavirus vaccination on the number of rotavirus hospitalisations in children aged <5 years in Belgium using vaccine efficacy data from clinical development trials. Data on the number of rotavirus-positive gastroenteritis hospitalisations in children aged <5 years between 1 June 2004 and 31 May 2006 (pre-vaccination study period or 1 June 2007 to 31 May 2010 (post-vaccination study period were analysed from nine hospitals in Belgium and compared with the modelled estimates. RESULTS: The model predicted a smaller decrease in hospitalisations over time, mainly explained by two factors. First, the observed data indicated indirect vaccine protection in children too old or too young for vaccination. This herd effect is difficult to capture in static Markov cohort models and therefore was not included in the model. Second, the model included a 'waning' effect, i.e. reduced vaccine effectiveness over time. The observed data suggested this waning effect did not occur during that period, and so the model systematically underestimated vaccine effectiveness during the first 4 years after vaccine implementation. CONCLUSIONS: Model predictions underestimated the direct medical economic value of rotavirus vaccination during the first 4 years of vaccination by approximately 10% when assessing

  4. Establishing specialized health services for professional consultation in euthanasia: experiences in the Netherlands and Belgium

    2009-12-01

    Full Text Available Abstract Background The Netherlands, Belgium, and Luxembourg have adopted laws decriminalizing euthanasia under strict conditions of prudent practice. These laws stipulate, among other things, that the attending physician should consult an independent colleague to judge whether the substantive criteria of due care have been met. In this context initiatives were taken in the Netherlands and Belgium to establish specialized services providing such consultants: Support and Consultation for Euthanasia in the Netherlands (SCEN and Life End Information Forum (LEIF in Belgium. The aim of this study is to describe and compare these initiatives. Methods We studied and compared relevant documents concerning the Dutch and Belgian consultation service (e.g. articles of bye-laws, inventories of activities, training books, consultation protocols. Results In both countries, the consultation services are delivered by trained physicians who can be consulted in cases of a request for euthanasia and who offer support and information to attending physicians. The context in which the two organisations were founded, as well as the way they are organised and regulated, is different in each country. By providing information on all end-of-life care matters, the Belgian LEIF seems to have a broader consultation role than the Dutch SCEN. SCEN on the other hand has a longer history, is more regulated and organised on a larger scale and receives more government funding than LEIF. The number of training hours for physicians is equal. However, SCEN-training puts more emphasis on the consultation report, whereas LEIF-training primarily emphasizes the ethical framework of end-of-life decisions. Conclusion In case of a request for euthanasia, in the Netherlands as well as in Belgium similar consultation services by independent qualified physicians have been developed. In countries where legalising physician-assisted death is being contemplated, the development of such a

  17. Neonatal thyroid-stimulating hormone concentrations in Belgium: a useful indicator for detecting mild iodine deficiency?

    Directory of Open Access Journals (Sweden)

    Stefanie Vandevijvere

    Full Text Available It has been proposed that neonatal thyroid-stimulating hormone (TSH concentrations are a good indicator of iodine deficiency in the population. A frequency of neonatal TSH concentrations above 5 mU/L below 3% has been proposed as the threshold indicating iodine sufficiency. The objective of the present study was to evaluate feasibility and usefulness of nation-wide neonatal TSH concentration screening results to assess iodine status in Belgium. All newborns born in Belgium during the period 2009-2011 (n = 377713 were included in the study, except those suffering from congenital hypothyroidism and premature neonates. The frequency of neonatal TSH concentrations above 5 mU/L from 2009 to 2011 in Belgium fluctuated between 2.6 and 3.3% in the centres using the same TSH assay. There was a significant inverse association between neonatal TSH level and birth weight. The longer the duration between birth and screening, the lower the TSH level. Neonatal TSH levels were significantly lower in winter than in spring or autumn and significantly lower in spring and summer than in autumn while significantly higher in spring compared to summer. In conclusion, despite that pregnant women in Belgium are mildly iodine deficient, the frequency of neonatal TSH concentrations above 5 mU/L was very low, suggesting that the neonatal TSH threshold proposed for detecting iodine deficiency needs to be re-evaluated. Although neonatal TSH is useful to detect severe iodine deficiency, it should not be recommended presently for the evaluation of iodine status in mildly iodine deficient regions.

    2012-11-01

    This study evaluates several ethical dilemmas of by dental practitioners treating persons with mental disabilities (PMD) by dentists in the Netherlands and Belgium. Ethical dental care for PMD is a hot topic. Worldwide different treatment strategies are used in the dental treatment of this patient group. In addition, cultural aspect seems to play an important role in the choices made. The latter can explain the difficulty in creating European and worldwide guidelines on this issue. A questionnaire was sent to dental practitioners interested in treating PMD persons both in the Netherlands and in Belgium including questions on the use of behaviour management techniques, use and attitude towards sedation and physical fixation and the cooperation with other health care personal. Behaviour management techniques and sedation are frequently used. Dentist of the Netherlands and Belgium in general reject the restraint of PMD persons. However, limited use of manual restraint in accordance with the carers and the close surrounding of the patient seems to be accepted. Dental practitioners are sometimes confronted with an emotional dilemma in treating PMD and the majority feels that it is a continuous challenge to obtain optimal result of the dental treatment.

    2016-07-01

    New EU regulations require more stringent country-of-origin labeling, while imports of broiler meat from non-EU countries are increasing. In light of these trends, we have studied citizens' and producers' perceptions of broiler meat originating from Belgium versus Brazil and their perception of broiler production in Belgium versus Brazil. A particular focus was the association between country of origin and perceived level of animal welfare. We also investigated the perception of scaling-up and outdoor access in terms of perceived level of animal welfare. Cross-sectional survey data was collected among Flemish citizens (n = 541) and broiler producers (n = 114). In accordance with literature on general farm animal welfare, both stakeholder types claimed to allocate great importance to broiler welfare and generally agreed with the Welfare Quality model of broiler welfare. Citizens disagreed with the producers that 1) consumers are not willing to pay more for higher welfare products, 2) that broilers suffer little, 3) that broiler welfare in current Belgian production units is generally non-problematic, 4) that scaling-up production units would not have a positive impact on profitability nor a profoundly negative impact on broiler welfare, and 5) that the impact of providing broilers with outdoor access is negative for consumers, farmers, and broilers. Country of origin had a strong influence on the perception of both broiler production and broiler meat. Belgian citizens, and producers (much more than citizens) considered nearly all aspects related to broiler production and broiler meat to be significantly superior for chicken produced in Belgium compared to Brazil. Further research should focus on how these perceptions influence purchase intentions and production decisions. Future avenues for research are to quantify market opportunities for country-of-origin labeling and to investigate to which extent stakeholders' perceptions correspond with reality.

    Changes in medical practices during transitions in regulating healthcare are rarely investigated. In this study, we investigated changes in medical end-of-life decisions with a possible or certain life-shortening effect (ELDs) that occurred during the legalization process of euthanasia in Belgium. We took representative random samples from deaths reported to registries in Flanders, Belgium in 1998 (n=3999) at the beginning of the process and in 2001 (N=5005), at the end of the process. The reporting physicians received an anonymous mail questionnaire about possible ELDs preceding the death involved. We found no significant shifts in the epidemiology of diseases between 1998 and 2001. The overall incidence of ELDs did not change. The incidence decreased for euthanasia, administering life-ending drugs without patient's explicit request, and alleviation of pain and symptoms with life-shortening co-intention. Incidence increased for alleviation of pain and symptom without life-shortening intention, and remained stable for non-treatment decisions. All decisions in 2001 were more often discussed with patients, their relatives and nurses. In 2001, continuous deep sedation was reported in 8.3% of deaths. We can conclude that physicians' end-of-life practices have substantially changed during the short but tumultuous legalization process of euthanasia in Belgium. Although follow-up research is needed to investigate the continuance of these changes, it is important for policy makers to keep in mind that social factors related to transitions in healthcare regulation may play an important role in the physicians' actual behaviour.

    Full Text Available The connection between nephropathia epidemica (NE and vegetation dynamics has been emphasized in recent studies. Changing climate has been suggested as a triggering factor of recently observed epidemiologic peaks in reported NE cases. We have investigated whether there is a connection between the NE occurrence pattern in Belgium and specific trends in remotely sensed phenology parameters of broad-leaved forests. The analysis of time series of the MODIS Enhanced Vegetation Index revealed that changes in forest phenology, considered in literature as an effect of climate change, may affect the mechanics of NE transmission.

    Policy measures affecting fertility, recently adopted in Belgium, are reviewed. The author notes that although responsibility for population matters has been delegated to the respective language groups, the responsibility for family law, divorce, abortion, social security, taxation, and labor policy remains a national responsibility. There are currently no measures in these areas adopted primarily for demographic reasons. Differences between the approaches taken by the French- and Dutch-speaking communities are noted. The author suggests that the French-speaking community has focused on problems relating to contraception and abortion, and the Dutch-speaking community has emphasized social welfare and family policy

    1992-01-01

    Between 1966 and 1987, in Liége--Belgium, 20,901 pregnant women were screened for toxoplasmosis. In this period an increase in seronegative women from 30% to 53% and a decrease in the seroconversion rate from 6.4% to 1.2% was observed. This decrease could be the result of advice and prophylactic measures. Due to the low rate of seroconversion (actually less than 1%), the cost/effectiveness of a systematic screening and fetal diagnosis should be investigated.

    2013-01-01

    Four sediment cores were collected in 2008 from the Misten ombrotrophic peat bog in the Northern part of the Hautes Fagnes Plateau in Belgium. Total mercury (Hg) concentrations were analyzed to investigate the intra-site variability in atmospheric Hg deposition over the past 1500 years. Mercury concentrations in the four cores ranged from 16 to 1100 μg kg− 1, with the maxima between 840 and 1100 μg kg− 1. A chronological framework was established using radiometric 210Pb and 14C dating of two ...

  10. Considerations on the operation of nuclear power plants and emergency plants. Special case of Belgium

    International Nuclear Information System (INIS)

    Nuclear power plant operation in Belgium is characterized by an effective utilization factor of 80.6% (which compares fairly well with world averages). It is important to analyse the reason for break-downs so as to improve operation. The paper reviews the procedures for emergency plans and considers separately the regulatory system and the internal rules. The nuclear operator is responsible for emergency plans on site while the Protection Civile (a public body) takes the necessary measures for protection of the public and the environment; a description follows of these tasks which are inter-related.

    Belgian judges may well be among the loneliest of their peers due to Belgium’s legal framework. In an attempt to counter this unfortunate situation, we will start by outlining some contours of “judicial loneliness” in Belgium through a brief discussion of secrecy of deliberations, the wide-spread unus iudex practice, as well as a more recent phenomenon: judges who ventilate certain aspirations and/or frustrations often end up being the epicenter of fierce public polemics. Secondly, we will em...

  12. Survey report of site selection process on the basis of local partnerships. Slovenia and Belgium

    International Nuclear Information System (INIS)

    Local partnership approach to achieve stakeholder consensus on low-level waste disposal, with particular focus on the siting of repositories are adopted in Europe. Especially in Belgium and Slovenia, final repository site had been decided in each country. The authors investigate on these two cases on the basis of interviews with implementing organizations for final disposal, representatives of local partnerships and citizens concerned so that the problem of introducing a local partnership in Japan can be examined. Its results are used as a reference for studying measures to determine the radioactive final repository site in Japan. (author)

  13. Annual progress report on nuclear data 1983 of the Central Bureau for Nuclear Measurements, Geel (Belgium)

    International Nuclear Information System (INIS)

    In this progress report of the Central Bureau for Nuclear Measurements at Geel (Belgium) researches related to neutron data and to non-neutron nuclear data are gathered. Neutron data are essentially related to cross-section measurements: for instance, concerning actinides, structural materials as Cr and Fe, fission products. Some studies are classified as concerning standard neutron data. Underlying physics is no forgotten neither than equipment (linear accelerator). Non-neutron nuclear data is concerned essentially with decay studies. Some compilations and evaluations are also given. Improvement of measurement and source preparation techniques is a part of this section

    Full Text Available Strategic partnerships in the biotechnology industry allow new technology-based firms to gain a foothold in this high-cost, high-risk industry. In this article, we examine the impact of strategic partnerships and open innovation on the success of new biotechnology firms in Belgium by developing multiple case studies of firms in regional biotechnology clusters. We find that, despite their small size and relative immaturity, new biotechnology firms are able to adopt innovative business models by providing R&D and services to larger firms and openly cooperating with them through open innovation.

    In the mining district of Plombières-La Calamine (East-Belgium), extensive Pb-Zn mining activities resulted in an important contamination of overbank sediments along the Geul river. Moreover, a huge amount of heavy metals is stored in a dredged mine pond tailing, which is located along the river. In the dredged mine pond tailing sediments, Pb-Zn minerals control the solubility of Zn, Pb and Cd. Although Pb, Zn and Cd display a lower solubility in overbank sediments compared to the mine tailin...

    Aphid parasitoids have good potential for crop protection. However, they have been poorly studied in Belgium, especially in terms of species diversity. Therefore, the aim of this work was to establish the first checklist for the country. To complete the list, aphid parasitoids were sampled in wheat and pea fields near Gembloux (Belgium), in 2013 and 2014. Among the identified species, Aphelinus asychis Walker, Aphelinus daucicola Kurdjumov, Aphelinus fusciscapus (Förster), Aphidius asteris Haliday, Aphidius eadyi Starý, Gonzalez & Hall, Praon barbatum Mackauer, and Trioxys auctus (Haliday) were recorded for the first time in Belgium. Thirty-two Aphidiinae and seven Aphelinus species were included in the checklist. It is hoped this study will stimulate further research, as species diversity is still low compared with neighbouring countries. PMID:27394473

    2015-10-01

    Tularemia is a zoonosis caused by Francisella tularensis that can be transmitted by several ways to human being and cause different clinical manifestations. We report three clinical cases of tularemia with ulceroglandular presentation in young males acquired during outdoor activities in Southern Belgium. Confirmation of the diagnosis was established by serology. Only three cases of tularemia have been reported in Belgium between 1950 and 2012 by the National Reference Laboratory CODA-CERVA (Ref Lab CODA-CERVA) but re-emergence of tularemia is established in several European countries and F. tularensis is also well known to be present in animal reservoirs and vectors in Belgium. The diagnosis of tularemia has to be considered in case of suggestive clinical presentation associated with epidemiological risk factors.

    Internationally, the importance of a coordinated effort to protect both biodiversity and public health is more and more recognized. These issues are often concentrated or particularly challenging in urban areas, and therefore on-going urbanization worldwide raises particular issues both for the conservation of living natural resources and for population health strategies. These challenges include significant difficulties associated with sustainable management of urban ecosystems, urban development planning, social cohesion and public health. An important element of the challenge is the need to interface between different forms of knowledge and different actors from science and policy. We illustrate this with examples from Belgium, showcasing concrete cases of human-nature interaction. To better tackle these challenges, since 2011, actors in science, policy and the broader Belgian society have launched a number of initiatives to deal in a more integrated manner with combined biodiversity and public health challenges in the face of ongoing urbanization. This emerging community of practice in Belgium exemplifies the importance of interfacing at different levels. (1) Bridges must be built between science and the complex biodiversity/ecosystem-human/public health-urbanization phenomena. (2) Bridges between different professional communities and disciplines are urgently needed. (3) Closer collaboration between science and policy, and between science and societal practice is needed. Moreover, within each of these communities closer collaboration between specialized sections is needed.

    2011-06-01

    Full Text Available Abstract Background Media awards to encourage responsible reporting of suicide have been introduced in several countries, including Australia, Belgium and Denmark. Aims This study aimed to examine the experiences of Australian, Belgian and Danish award recipients in preparing stories on suicide, and consider the impacts of the awards for these recipients and for media professionals more broadly. Method We conducted semi-structured telephone interviews with the majority (14 out of 15 of past recipients of the awards in the three countries of interest. Results Media awards appear to show promise as a method of reinforcing national and international media guidelines on reporting suicide. The recipients of awards were proud to have had their achievements recognized in this way, and had developed a heightened awareness of the issues inherent in reporting suicide. Although relatively few had prepared subsequent stories on suicide, a number had been given opportunities to provide advice to other media professionals about how best to approach this sensitive topic. Recipients viewed the awards as an important means by which good quality reporting can be rewarded, and a springboard for raising community awareness about suicide. Conclusion The experience from Australia, Belgium and Denmark suggests that media awards which recognize responsible reporting of suicide are extremely worthwhile.

  1. 500 years of coppice-with-standards management in Meerdaal Forest (Central Belgium

    Directory of Open Access Journals (Sweden)

    Vandekerkhove K

    2016-08-01

    Full Text Available For centuries, coppice and coppice-with-standards were the main forest management systems in the northern and central parts of present Belgium. A high population density and a low forest cover in the whole region resulted in a high demand for wood, therefore strict regulations and management regimes were necessary to prevent overexploitation. We illustrate this with a well-documented case, that of Meerdaal Forest in Central Belgium, with reference to other sites in the region. Meerdaal Forest is a woodland 30 km east of Brussels. For centuries its high quality timber stands, especially oak, were managed as coppice-with-standards, with a gradually increasing share of standard trees. Using archive documents and ancient maps, we have reconstructed how this coppice-with-standard management has been developed and optimized over a period of about 500 years. Changes in cutting cycles and configurations were discerned, with a gradual increase of the importance of the standard layer over time. The analysis also showed how wood production could be successfully combined with other sources of income like grazing and pannage. We conclude that former managers of Meerdaal Forest, notwithstanding their lack of scholarship and reference works, developed a state-of-the-art sustainable and flexible management regime that allowed to provide high revenues during many centuries.

    The current article reports on the first large-scale prevalence study on interpersonal violence against children in sport in the Netherlands and Belgium. Using a dedicated online questionnaire, over 4,000 adults prescreened on having participated in organized sport before the age of 18 were surveyed with respect to their experiences with childhood psychological, physical, and sexual violence while playing sports. Being the first of its kind in the Netherlands and Belgium, our study has a sufficiently large sample taken from the general population, with a balanced gender ratio and wide variety in socio-demographic characteristics. The survey showed that 38% of all respondents reported experiences with psychological violence, 11% with physical violence, and 14% with sexual violence. Ethnic minority, lesbian/gay/bisexual (LGB) and disabled athletes, and those competing at the international level report significantly more experiences of interpersonal violence in sport. The results are consistent with rates obtained outside sport, underscoring the need for more research on interventions and systematic follow-ups, to minimize these negative experiences in youth sport.

    2016-10-01

    In several European countries, including Belgium, the rapid ageing of the migrant population has emerged only recently on the political agenda. The aim of this literature review is threefold. Firstly, it provides a review of the available studies on the accessibility and use of institutional care services by Moroccan and Turkish migrants in the Flemish part of Belgium including Flanders and Brussels. Secondly, it identifies their specific needs regarding elderly care services. Finally, it provides an overview of the way in which Belgian policy has dealt with the issue of migration and elderly care. Literature published between 1965 and 2014 and relevant to the Belgian context has been included. This search yielded 21 references, of which 8 empirical studies, 5 policy literature, 3 theoretical studies, 3 news articles and 2 popularized reports. Mainstream elderly care remains relatively inaccessible for these migrants due to the language and a series of cultural and religious barriers, a low level of education, financial constraints, a lack of knowledge of health care systems, and the so-called return and care dilemmas. Their religious and cultural needs are currently not met by elderly care services. The inclusive and neutral Belgian policy seems to pay insufficient attention to these issues. PMID:26141810

  4. Lymphoscintigraphy in the management of lymphoedemas and their health costs reimbursement in Belgium

    International Nuclear Information System (INIS)

    Limb edemas of lymphatic origin, either primary, or secondary, represent a chronic disease sometimes heavy to bear by patients who suffer from them. These lymphoedemas imply specific care by physical therapists trained to the use of different therapeutic approaches. Until a few years, only the treatments of secondary lymphoedemas after radiotherapy and/or complete nodal dissection for cancer were reimbursed by the national health insurance system in Belgium. The introduction of the primary congenital lymphoedemas as a disease also reimbursed raised several problems and led to a redefinition of these situations and of their cares. The definition and classification of the lymphoedemas in view of the reimbursement of their treatments by the national health insurance system are now officially based (not only on the sole clinical history but) mainly on their clinical severity and/or also on the result of their lympho-scintigraphic investigation (according to a methodological protocol and to diagnostic criteria adopted at the national level). The reimbursements of the treatments by the physical therapists were also adapted and improved. The lympho-scintigraphic investigations of the limb edemas became so essential in the management of the lymphedematous situations and in the reimbursement of their physical treatments in Belgium.

    The growing concern among the climate scientists is that the frequency of weather extremes will increase as a result of climate change. European society, for example, is particularly vulnerable to changes in the frequency and intensity of extreme events such as heat waves, heavy precipitation, droughts, and wind storms, as seen in recent years [1,2]. A more than 50% of the land is occupied by managed ecosystem (agriculture, forestry) in Belgium. Moreover, among the many extreme weather conditions, drought counts to have a substantial impact on the agriculture and ecosystem of the affected region, because its most immediate consequence is a fall in crop production. Besides the technological advances, a reliable estimation of weather conditions plays a crucial role in improving the agricultural productivity. The above mentioned reasons provide a strong motivation for a research on the drought and its impacts on the economical and agricultural aspects in Belgium. The main purpose of the presented work is to map atmospheric drought Return-Levels (RL), as first insight for agricultural drought, employing spatial modelling approaches. The likelihood of future drought is studied on the basis of precipitation deficit indices for four vegetation types: water (W), grass (G), deciduous (D) and coniferous forests (C) is considered. Extreme Value Theory (EVT) [3,4,5] as a branch of probability and statistics, is dedicated to characterize the behaviour of extreme observations. The tail behaviour of the EVT distributions provide important features about return levels. EVT distributions are applicable in many study areas such as: hydrology, environmental research and meteorology, insurance and finance. Spatial Generalized Extreme Value (GEV) distributions, as a branch of EVT, are applied to annual maxima of drought at 13 hydro-meteorological stations across Belgium. Superiority of the spatial GEV model is that a region can be modelled merging the individual time series of

    2016-04-01

    During several years, a series of geophysical surveys have been carried out in East Belgium to study the seismically active Hockai Fault Zone (HFZ). The most prominent earthquake that occurred in that fault zone is the 1692 Verviers Earthquake with a magnitude of M6-6.5; it is also the largest historical seismic event in NW Europe. The geomorphic impact of the fault zone is expressed by several landslides, NW-SE orientated scarps and paleo-valleys generated by river diversions. The NW part of the HFZ (near Battice, Belgium) is also known as the Graben de la Minerie; here, geophysical measurements confirmed the presence of a series of fault scarps and helped imaging the general basin structure related to vertical offsets of coal seams that had been found during former mining works. In the southern part of the HFZ, the ENE-SWS orientated Paleo-Warche-Valley (that was formed before upstream capturing of the Warche River) crosses the fault zone over a distance of 5 km. The shallow subsurface of this area was further investigated by geophysics to identify fault structures. The work presented here is focused on the SE prolongation of the HFZ (region of Malmedy, Belgium). Two new clear morphological markers unknown before were detected through analysis of a LiDAR-DEM recently published by the Walloon Region. The following geological-geomorphic survey confirmed the presence of a NNW-SSE oriented, 100 m long and 20 m high, scarp and an associated landslide (about 8 ha) with minimum age of 300 years. The landslide was formed in the Poudingue de Malmedy, a local Permian conglomerate lying on top of a quartz-phyllite bedrock. Different geophysical methods were applied to investigate the subsurface: microseismic measurements (H/V method), seismic refraction tomography (combined with surface wave analysis) and electrical resistivity tomography. To establish the structural relationship between the fault scarp and the landslide and to estimate the offset of the Poudingue de

    Full Text Available Ever since 2000, VITO has been working on the Pegasus project. This involves a solar High Altitude Long Endurance Unmanned Aerial Vehicle (HALE-UAV as a stratospheric platform for Earth Observation. This aircraft, called Mercator, is designed to fly for prolonged duration at altitudes up to 20 km. The technology has been proven by the aircraft’s manufacturer, QinetiQ (UK by a series of test flights over the past years, culminating in a world record flight in duration of over 14 days duration. All test flights, however, were conducted in test ranges, where other air traffic does not pose a concern. Pegasus aims to demonstrate the viability of stratospheric Earth Observation in Belgium, as a proof of concept for other areas around the world. The Belgian air space is completely different from a test range. More than 1 million aircraft movements take place over Belgium and Luxembourg every year, with routes to Amsterdam, Paris, Frankfurt, and London. Although Pegasus will usually be flying above this dense traffic, it does interfere with it during ascent and landing, and needs to be monitored during the cruise phase for safety reasons. Air traffic management in Belgium is a shared responsibility of Air Navigation Service Providers (ANSPs Belgocontrol (civil, ATCC (military and Eurocontrol MUAC (high altitude. In 2010, VITO applied for a permit-to-fly for a test flight of one day duration. Although the Belgian Civil Aviation Authority (CAA had issued a regulation on UAVs in 2007, it was the first application for a permit to fly in controlled airspace. The Belgian CAA decided to use it as a test for the procedures as well. A prerequisite for flying in controlled airspace was that the aircraft has to carry a mode-S transponder and navigation lights. During first half of 2010, the ANSPs collaborated on a Temporary Operations Instruction and studied the safety impact of this flight on their operations. As an outcome, they decided that the Pegasus

    Organ donation after euthanasia has been performed more than 40 times in Belgium and the Netherlands together. Preliminary results of procedures that have been performed until now demonstrate that this leads to good medical results in the recipient of the organs. Several legal aspects could be changed to further facilitate the combination of organ donation and euthanasia. On the ethical side, several controversies remain, giving rise to an ongoing, but necessary and useful debate. Further experiences will clarify whether both procedures should be strictly separated and whether the dead donor rule should be strictly applied. Opinions still differ on whether the patient's physician should address the possibility of organ donation after euthanasia, which laws should be adapted and which preparatory acts should be performed. These and other procedural issues potentially conflict with the patient's request for organ donation or the circumstances in which euthanasia (without subsequent organ donation) traditionally occurs.

    In the framework of applying econophysics ideas in religious topics, the finances of the Antoinist religious movement organised in Belgium between 1920 and 2000 are studied. The interest of investigating financial aspects of such a, sometimes called, sect stems in finding characteristics of conditions and mechanisms under which definitely growth and decay features of communities can be understood. The legally reported yearly income and expenses between 1920 and 2000 are studied. A three wave asymmetric regime is observed over a trend among marked fluctuations at times of crises. The data analysis leads to the proposition of a general mechanistic model taking into account an average GDP growth, oscillatory monetary inflation and a logistic population drift.

    The place of simulation in medical education, particularly in anesthesia, appears to be more and more evident. However, the history of simulation in Belgium showed that the associated costs remain a barrier. The use of 'in situ' simulation, defined as the practice of simulation in the usual workplace, could solve the problem of providing access to this educational tool.

    Seasonal changes in the diet composition and trophic niche overlap were examined for the dominant members of the fish assemblage of the turbid low-salinity zone of the Scheldt estuary (Belgium). Samples of fish were taken in the cooling water of a power plant. Juveniles of eight species dominated...... the fish assemblage: two goby species, herring, sprat, bass, flounder, eel and pikeperch. Together, they had preyed upon 31 different prey taxa. Calanoid copepods and hyperbenthic mysids were the most important prey items with macrobenthic invertebrates being largely ignored. Pair-wise comparisons...... of trophic niche overlap showed that, in general, niche overlap between individuals of the same species was significantly higher than overlap between individuals from different species, suggesting that the available food resources were partitioned. The total annual prey consumption by the dominant fish...

    Among the numerous diseases that can attack pome fruit trees, apple proliferation and pear decline, both caused by a phytoplasma ('Candidatus Phytoplasma mali' (AP) and 'Ca. P. pyri' (PD), respectively), may result into important losses of quality and quantity of the crop. Until a few years ago, no scientific and reliable data on their presence in Belgium was available and so a 2-year survey was organised to obtain more detailed information on the status of both pathogens. Root and leaf samples collected in commercial orchards were analysed using molecular detection tools and tested positive for both phytoplasmas. Additionally, the presence and infectivity of Psyllidae, vectors of AP and PD, was assessed during this survey but no infected Cacopsylla-species were found. Lab trials revealed its vector capacity at the end of summer and autumn and its migration pattern 80 m in line and 10.5 m across trees in an orchard.

    An outbreak of leptospirosis occurred in the South of Belgium, during August 2012, in teenagers who participated in two consecutive adventure scout camps near the Semois river. Among the symptomatic patient population (ten scouts), clinical manifestations included headache (70%), myalgia (50%), fever (50%), bilateral conjunctival injection (50%), general malaise (30%), vomiting (20%), anorexia (20%) and cough (20%). Some of the cases presented elevated blood creatinine (40%), or proteinuria (30%). Three patients were confirmed by serology and one by polymerase chain reaction. Potential risk factors included direct contact with a muskrat and indirect contact with potentially contaminated environments including the river water. Prospective environmental investigation carried out near the river banks 2 weeks after the outbreak identified Ondatra zibethicus (muskrat) as one Leptospira sp. reservoir. PMID:25311398

    Silky bent grass (Apera spica-venti (L.) P. Beauv.) is a common weed of cereal crops widely spread in Northern and Easthern Europe (Germany, Czech Republic,...), Northern Asia, Siberia and Canada. Up to now, no resistant case has been detected in Belgium but some chemical weeding failures have been observed in Wallonia fields. During summer 2011, 37 seed samples of Apera spica-venti were collected in Wallonia and submitted to resistance tests in controlled conditions. Three modes of action were tested: acetyl coenzyme-A carboxylase inhibitors (pinoxaden and cycloxydim), acetolactate synthase inhibitors (mesosulfuron+iodosulfu-ron, pyroxsulam and sulfometuron) and photosynthesis inhibitors (isoproturon). One susceptible standard population was included in the test in order to validate it and to permit wild populations classification according to "R" rating system developed by Moss et al (2007). Most of populations were susceptible but some populations showed resistance to at least one of the three tested modes of action.

    The place of simulation in medical education, particularly in anesthesia, appears to be more and more evident. However, the history of simulation in Belgium showed that the associated costs remain a barrier. The use of 'in situ' simulation, defined as the practice of simulation in the usual workplace, could solve the problem of providing access to this educational tool. Indeed, it allows reducing equipment and manpower costs: the needed equipment comes from the hospital, and supervision and organization are provided by staff members. It also provides access to simulation for a larger number of individuals on site. The environment is more realistic because the participants operate in their usual workplace, with their customary equipment and team. Furthermore, 'in situ' simulation allows participation of the paramedical staff. This allows developing skills related to teamwork and communication. Despite those numerous advantages, several difficulties persist. The associated logistic and organizational constraints can be cumbersome.

    Full Text Available Recent research has indicated the continuation of a hunting-fishing-gathering way of life in the lower Scheldt basin (Belgium for over a millennium after the first arrival of agriculture in the middle Scheldt. Current evidence suggests multiple hiatuses in cultural change from the late 6th-late 5th millennium BC. This article provides the outline of a model that seeks to explain these hiatuses from the perspective of indigenous hunter-fisher-gatherer cultural landscapes. The outline investigates the significance of palaeoecological and social contexts in relation to contact and cultural transmission processes during the transition to agriculture. Recent ethnoarchaeological research from hunter-fisher-gatherers in temperate and boreal environments is referenced as a structural analogy for illuminating the important relationship between territoriality and social mediation within hunter-gatherer groups at the Mesolithic-Neolithic interface.

    Adapting illicit drug policy strategies requires detailed knowledge on types and amounts of substances consumed by the target population. In this study, we applied wastewater-based epidemiology to detect spatio-temporal changes in the relative amounts of stimulants (amphetamine, methamphetamine, methylenedioxymethamphetamine (MDMA), cocaine) used in seven locations in Belgium over 2011-2015. Clear geographical differences were observed with stimulant users in large cities (Antwerp, Brussels) showing a preference for cocaine, while amphetamine use was most abundant in smaller cities (Geraardsbergen, Koksijde, Lier, Ninove, Ostend). Results obtained across õdifferent years revealed that the investigated substances had a stable share in the total amount of stimulants used, suggesting that habits of stimulant use remained constant, although differences in absolute amounts were observed across years. Investigation of the weekly pattern in stimulant use showed an increase in the use of MDMA on the weekends compared to cocaine and amphetamine. PMID:27251771

    Trichinellosis is a rare parasitic zoonosis caused by Trichinella following ingestion of raw or undercooked meat containing Trichinella larvae. In the past five years, there has been a sharp decrease in human trichinellosis incidence rates in the European Union due to better practices in rearing domestic animals and control measures in slaughterhouses. In November 2014, a large outbreak of trichinellosis occurred in Belgium, related to the consumption of imported wild boar meat. After a swift local public health response, 16 cases were identified and diagnosed with trichinellosis. Of the 16 cases, six were female. The diagnosis was confirmed by serology or the presence of larvae in the patients’ muscle biopsies by histology and/or PCR. The ensuing investigation traced the wild boar meat back to Spain. Several batches of imported wild boar meat were recalled but tested negative. The public health investigation allowed us to identify clustered undiagnosed cases. Early warning alerts and a coordinated response remain indispensable at a European level.

    In the framework of applying econophysics ideas in religious topics, the finances of the Antoinist religious movement organized in Belgium between 1920 and 2000 are studied. The interest of investigating financial aspects of such a, sometimes called, sect stems in finding characteristics of conditions and mechanisms under which definitely growth AND decay features of communities can be understood. The legally reported yearly income and expenses between 1920 and 2000 are studied. A three wave asymmetric regime is observed over a trend among marked fluctuations at time of crises. The data analysis leads to propose a general mechanistic model taking into account an average GDP growth, an oscillatory monetary inflation and a logistic population drift.

    The aims of this study were to: i) measure personal exposure in the Global System for Mobile communications (GSM) 900MHz downlink (DL) frequency band with two systems of exposimeters, a personal distributed exposimeter (PDE) and a pair of ExpoM-RFs, ii) compare the GSM 900MHz DL exposures across various microenvironments in Australia and Belgium, and iii) evaluate the correlation between the PDE and ExpoM-RFs measurements. Personal exposure data were collected using the PDE and two ExpoM-RFs simultaneously across 34 microenvironments (17 each in Australia and Belgium) located in urban, suburban and rural areas. Summary statistics of the electric field strengths (V/m) were computed and compared across similar microenvironments in Australia and Belgium. The personal exposures across urban microenvironments were higher than those in the rural or suburban microenvironments. Likewise, the exposure levels across the outdoor were higher than those for indoor microenvironments. The five highest median exposure levels were: city centre (0.248V/m), bus (0.124V/m), railway station (0.105V/m), mountain/forest (rural) (0.057V/m), and train (0.055V/m) [Australia]; and bicycle (urban) (0.238V/m), tram station (0.238V/m), city centre (0.156V/m), residential outdoor (urban) (0.139V/m) and park (0.124V/m) [Belgium]. Exposures in the GSM900 MHz frequency band across most of the microenvironments in Australia were significantly lower than the exposures across the microenvironments in Belgium. Overall correlations between the PDE and the ExpoM-RFs measurements were high. The measured exposure levels were far below the general public reference levels recommended in the guidelines of the ICNIRP and the ARPANSA.

    Dioxins are harmful persistent organic pollutants (POPs) to which humans are exposed mostly via the consumption of animal products. They can enter the food chain at any stage, including crop fertilization. Fertilizers belong to several categories: synthetic chemicals providing the essential elements (mostly N, P and K) that are required by the crops but also organic fertilizers or amendments, liming materials, etc. Ninety-seven samples of fertilizers were taken in Belgium during the year 2011 and analyzed after a soft extraction procedure for polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and dioxin-like polychlorinated biphenyls (DL-PCBs) using GC-IDHRMS. Only small qualitative differences could be observed between the main fertilizer categories since the PCDD:PCDF:DL-PCB average ratio obtained with the results expressed in TEQ was often close to 30:30:40 (typically for sewage sludge) or 40:30:30 (typically for compost). The median dioxin levels determined were generally lower than recorded previously and were the highest for sewage sludge and compost (5.6 and 5.5 ng TEQ/kg dry weight (dw), respectively). The levels in other fertilizers were lower including manure for which the median value was only 0.2 ng TEQ/kg dw. Several fertilization scenarios relying on the use of those fertilizers were assessed taking into consideration the application conditions prevailing in Belgium. From this assessment it could be concluded that the contribution of fertilizers to the overall soil contamination will be low by comparison of other sources of contamination such as atmospheric depositions. At the field scale, intensive use of compost and sewage sludge will increase dramatically the dioxin inputs compared with other fertilization practices but this kind of emission to the soil will still be relatively low compared to the dioxin atmospheric depositions.

  14. House Sparrows Do Not Constitute a Significant Salmonella Typhimurium Reservoir across Urban Gradients in Flanders, Belgium.

    In recent decades major declines in urban house sparrow (Passer domesticus) populations have been observed in north-western European cities, whereas suburban and rural house sparrow populations have remained relatively stable or are recovering from previous declines. Differential exposure to avian pathogens known to cause epidemics in house sparrows may in part explain this spatial pattern of declines. Here we investigate the potential effect of urbanization on the development of a bacterial pathogen reservoir in free-ranging house sparrows. This was achieved by comparing the prevalence of Salmonella enterica subspecies enterica serotype Typhimurium in 364 apparently healthy house sparrows captured in urban, suburban and rural regions across Flanders, Belgium between September 2013 and March 2014. In addition 12 dead birds, received from bird rescue centers, were necropsied. The apparent absence of Salmonella Typhimurium in fecal samples of healthy birds, and the identification of only one house sparrow seropositive for Salmonella spp., suggests that during the winter of 2013-2014 these birds did not represent any considerable Salmonella Typhimurium reservoir in Belgium and thus may be considered naïve hosts, susceptible to clinical infection. This susceptibility is demonstrated by the isolation of two different Salmonella Typhimurium strains from two of the deceased house sparrows: one DT99, typically associated with disease in pigeons, and one DT195, previously associated with a passerine decline. The apparent absence (prevalence: house sparrows and the association of infection with clinical disease suggests that the impact of Salmonella Typhimurium on house sparrows is largely driven by the risk of exogenous exposure to pathogenic Salmonella Typhimurium strains. However, no inference could be made on a causal relationship between Salmonella infection and the observed house sparrow population declines.

  15. Belgium's 'Comite de Controle de l'Electricite et du Gaz' and European cartel law

    International Nuclear Information System (INIS)

    The Comite de Controle de l'Electricite et du Gaz, was formed in 1955 from the three employee's unions, the employers association, as well as government officials and the national executives, and is responsible for the technical, economical and pricing policy control of the electricity and gas sectors. Among others, it fixes gas and electricity rates, controls rationalization of the gas and electricity sectors by the electricity supply companies (EVU) and gas supply companies (GVU) and examines the project lying of the renewue and the investments of the parties. Initially, the author describes the coming into being as well as the functions and the development of the Comite and illustrates the structure of the gas and electricity supply in Belgium. The crucial point of the investigation is the question whether the work of the Comite de Controle is in harmony with the European cartel law. First of all, there is a subsumption under Article 85, section 1 of the EEC Treaty and then in regard to the exemption provision in Article 90, Section 2 of the EEC Treaty or the exemption possibility pursnant to Article 85, Section 3 of the EEC Treaty, the author concludes that the work of the Comite de Controle is incompatible with the European cartel law. Among others, the dissertation includes comments on the application of the EEC Treaty to the energy sector, on the peculiarities of energy supply as well as a comparison of electricity and gas prices for households and industry in Belgium, France, Luxembourg, the Netherlands and the Federal Republic of Germany. Furthermore, the author apports liberalization of the energy market and points out the advantages of free competition. (orig./HP)

    In many European countries there is a public debate about the acceptability and regulation of euthanasia. In 2002, Belgium became the second country after the Netherlands to enact a law on euthanasia. Although euthanasia rarely occurs, the complexity of the clinical-ethical decision making surrounding euthanasia requests and the need for adequate support reported by caregivers, means that healthcare institutions increasingly need to consider how to responsibly handle euthanasia requests. The development of written ethics policies on euthanasia may be important to guarantee and maintain the quality of care for patients requesting euthanasia. The aim of this study was to determine the prevalence, development, position, and communication of written ethics policies on euthanasia in Flemish nursing homes. Data were obtained through a cross-sectional mail survey of general directors of all Catholic nursing homes in Flanders, Belgium. Of the 737 nursing homes invited to participate, 612 (83%) completed the questionnaire. Of these, only 15% had a written ethics policy on euthanasia. Presence of an ethics committee and membership of an umbrella organization were independent predictors of whether a nursing home had such a written ethics policy. The Act on Euthanasia and euthanasia guidelines advanced by professional organizations were the most frequent reasons (76% and 56%, respectively) and reference sources (92% and 64%, respectively) for developing ethics policies on euthanasia. Development of ethics policies occurred within a multidisciplinary context. In general, Flemish nursing homes applied the Act on Euthanasia restrictively by introducing palliative procedures in addition to legal due care criteria. The policy was communicated to the consulting general practitioner and nurses in 74% and 89% of nursing homes, respectively. Although the overall prevalence of ethics policies on euthanasia was low in Flemish nursing homes, institution administrators displayed growing

  17. Which transition comes first? Urban and demographic transitions in Belgium and Sweden

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Background: Several theories compete to explain the main drivers of urbanisation, past and present, in relation to both demographic transition and economic development. One hypothesis is that rural-to-urban migration is the driver of urbanisation; another is that urban mortality decline actually triggered urban transition. Objective: This paper reconsiders the relationship between demographic (vital migration and urban transitions by analysing the long-term contribution of natural and migratory movements to urban transition. The respective contributions of birth, death, and migration and their timing will indicate whether economic development, through labour force migration, or vital transition mainly determines urban transition. Methods: After examining the spatial dimension of the demographic transition theory, we use 19th and 20th century series on Sweden and Belgium to better identify the migration component of urban transition through the computation of growth difference between urban and rural areas, accounting for the often neglected reclassification effect. Results: In both Sweden and Belgium, migration is the direct or indirect (through reclassification engine of urban transition and its contribution precedes the onset of vital transition, while the vital transition has a secondary, unstable, and negative role in the urban transition. Conclusions: Changes in the economic sphere are reinstated as the underlying cause of population change, acting through the shift of human capital in space. Methodological consequences are then drawn for analysing vital and urban transitions in an increasingly interdependent world. Contribution: The paper contributes to the theoretical literature on urban and demographic transitions in relation to economic development. The proposed method evaluates migration contribution without having to measure it.

    Four sediment cores were collected in 2008 from the Misten ombrotrophic peat bog in the Northern part of the Hautes Fagnes Plateau in Belgium. Total mercury (Hg) concentrations were analyzed to investigate the intra-site variability in atmospheric Hg deposition over the past 1500 years. Mercury concentrations in the four cores ranged from 16 to 1100 {mu}g kg{sup -1}, with the maxima between 840 and 1100 {mu}g kg{sup -1}. A chronological framework was established using radiometric {sup 210}Pb and {sup 14}C dating of two cores (M1 and M4). Pollen horizons from these two cores were correlated with data from two additional cores, providing a consistent dating framework between all the sites. There was good agreement between atmospheric Hg accumulation rates in the four cores over time based on precise age dating and pollen chronosequences. The average Hg accumulation rate before the influence of human activities (from 500 to 1300 AD) was 1.8 {+-} 1 {mu}g m{sup -2} y{sup -1} (2SD). Maximum Hg accumulation rates ranged from 90 to 200 {mu}g m{sup -2} y{sup -1} between 1930 and 1980 AD. During the European-North American Industrial Revolution, the mean Hg accumulation rate exceeded the pre-Industrial values by a factor of 63. Based on comparisons with historical records of anthropogenic activities in Europe and Belgium, the predominant regional anthropogenic sources of Hg during and after the Industrial Revolution were coal burning and smelter Hg emissions. Mercury accumulation rates and chronologies in the Misten cores were consistent with those reported for other European peat records. -- Highlights: Black-Right-Pointing-Pointer Study of Hg concentration in four cores from Belgian peat bog.

  1. First isolation of hepatitis E virus genotype 4 in Europe through swine surveillance in the Netherlands and Belgium.

    Directory of Open Access Journals (Sweden)

    Renate W Hakze-van der Honing

    Full Text Available Hepatitis E virus (HEV genotypes 3 and 4 are a cause of human hepatitis and swine are considered the main reservoir. To study the HEV prevalence and characterize circulating HEV strains, fecal samples from swine in the Netherlands and Belgium were tested by RT-PCR. HEV prevalence in swine was 7-15%. The Dutch strains were characterized as genotype 3, subgroups 3a, 3c and 3f, closely related to sequences found in humans and swine earlier. The HEV strains found in Belgium belonged to genotypes 3f and 4b. The HEV genotype 4 strain was the first ever reported in swine in Europe and an experimental infection in pigs was performed to isolate the virus. The genotype 4 strain readily infected piglets and caused fever and virus shedding. Since HEV4 infections have been reported to run a more severe clinical course in humans this observation may have public health implications.

    In 2013 and 2014, routine surveillance for invasive mosquito species was implemented in Belgium at 13 potential points of entry. Following the introduction of Aedes (Stegomyia) albopictus (Skuse 1895) to Belgium via a used tyre import company (Vrasene, Province of East Flanders) in July 2013, one female and 17 larvae were collected outdoors during a period of intensive surveillance in summer and autumn 2013, but no control measures were implemented. Although climatic conditions were suitable during the winter of 2013-2014, this reproducing population did not overwinter. Lack of genetic variation, incomplete diapause adaptation and egg desiccation due to long dry periods during diapause or competition with endemic species are possible reasons. More studies on the diapause/longevity of Ae. albopictus eggs in northern temperate climatic conditions and on the competition with endemic species in western and central Europe are warranted to assess the potential for this invasive mosquito to overwinter. Furthermore, following the detection of four Ae. albopictus larvae in a shipment of lucky bamboo at the port of Antwerp in August 2014, one female, one male, 11 pupae and six larvae were collected at the destined lucky bamboo company (Lochristi, Province of East Flanders) in autumn 2014. In this case, immediate control measures were successfully implemented at the nursery. Because of increasing threats and the absence of an invasive mosquito species control policy in Belgium, the need for a permanent vector surveillance and control plan has never been so high.

    Full Text Available The purpose of thie paper is to assess the marketing management capabilities of SMEs producing traditional food products in the EU through thge development of a self-evaluation tool.SMEs represent the greater part of European food firms and they find it very difficult to adapt to market changes, and to compete with big enterprises. In this context, marketing management capabilities play a key role in good SME performance in the market. The self-evaluation tool is developed in the innovative form of an interactive questionnaire published on the web. At the moment, the sample is composed by 60 traditional food producers located in three member states (Belgium, Italy, and Hungary belonging to different sectors (cheese, beer, dry ham, sausage and white pepper. The data were analysed with cluster analysis. The results of the survey revealed that most of the firms analysed show weaknesses in marketing management capabilities. Nevertheless, cluster analysis pointed out a group of firms (22% of the sample with high performances in all the stages of marketing management process, which can be defined market oriented in terms of MARKOR approach. Most firms showed difficulties in analysing the competitive environment in which they operate, and in controlling the achievement of the marketing objectives. Moreover, the survey showed that, generally, micro sized firms perform worse than small and medium enterprises. Nevertheless, in some cases micro firms achieved high performances revealing that the firm size is not a so insuperable constraint to reach good results in marketing.

  18. Holocaust or Benevolent Paternalism? Intergenerational Comparisons on Collective Memories and Emotions about Belgium's Colonial Past

    Directory of Open Access Journals (Sweden)

    2010-05-01

    Full Text Available After publication of Adam Hochschild's King Leopold's Ghost in 1998, asserting that King Leopold II had been responsible for a "holocaust" in the Congo and the heated public debate this provoked, we set out to study Belgian people's reactions to these accusations. In two studies we compared collective memories of and emotions associated with Belgium's colonial action in the Congo in different generations. Results show higher levels of collective guilt and support for reparative actions among young adults than among older generations. This difference can be explained either by referring to the different ideological backgrounds in which different generations were socialized, as evidenced by stark differences in collective memories of colonialism, or by referring to the influence of national identification. Indeed, people could adapt their representations of colonialism in order to avoid experiencing a social identity threat. However, evidence for the identity-protecting functions of collective memories and collective emotions was only found in the older generations: young people held negative representations of colonialism independently of their level of national identification. We refer to the normative dimension of collective guilt to interpret these results.

    Since many micro-organisms are a biological hazard, they have been categorised into risk groups by many countries and organisations and classification lists have been developed. Current classification systems rely on criteria defined by the World Health Organization, which cover the severity of the disease the micro-organism might cause, its ability to spread and the availability of prophylaxis or efficient treatment. Animal pathogens are classified according to the definitions of the World Organisation for Animal Health, which also consider economic aspects of disease. In Europe, classification is often directly linked to containment measures. The Belgian classification system, however, only considers the inherent characteristics of the micro-organism, not its use, making the risk classification independent of containment measures. A common classification list for human and animal pathogens has been developed in Belgium using as comprehensive an approach as possible. The evolution of scientific knowledge will demand regular updating of classification lists. This paper describes the Belgian risk classification system and the methodology that was used for its peer-reviewed revision (with a focus on animal pathogens).

    Plant phenology is a good bio-indicator for climate change, and this has brought a significant increase of interest. Many kinds of phenology models have been developed to analyze and predict the phenological response to climate change, and those models have been summarized into one kind of unified model, which could be applied to different species and environments. In our study, we selected seven European woody plant species (Betula verrucosa, Quercus robur pedunculata, Fagus sylvatica, Fraxinus excelsior, Symphoricarpus racemosus, Aesculus hippocastanum, Robinia pseudoacacia) occurring in five sites distributed across Belgium. For those sites and tree species, phenological observations such as bud burst were available for the period 1956 - 2002. We also obtained regional downscaled climatic data for each of these sites, and combined both data sets to test the unified model. We used a Bayesian approach to generate distributions of model parameters from the observation data. In this poster presentation, we compare parameter distributions between different species and between different sites for individual species. The results of the unified model show a good agreement with the observations, except for Fagus sylvatica. The failure to reproduce the bud burst data for Fagus sylvatica suggest that the other factors not included in the unified model affect the phenology of this species. The parameter series show differences among species as we expected. However, they also differed strongly for the same species among sites.Further work should elucidate the mechanism that explains why model parameters differ among species and sites.

    In Belgium, rotavirus vaccination has been recommended and partially reimbursed since October 2006. Through a retrospective survey in 2012, we estimated the coverage rate of the rotavirus vaccination in Flanders among infants born in 2010. Using a standardised questionnaire, 874 families were interviewed at home, collecting information on demographic characteristics, socio-economic background and documented vaccination history (updated from medical files and vaccination database, if needed). Adherence to the recommended age for vaccination (8, 12 and 16 weeks) was also assessed. The coverage rate for two doses of rotavirus vaccination was 92.2% (95% confidence interval: 90.2-93.8). Respectively 31.7% and 10.1% of the children received their first and second dose at the recommended age. Incomplete vaccination was often a deliberate choice of the parents. Only eight children (1%) were vaccinated after the maximum age of 26 weeks. Factors identified by multiple logistic regression as related to incomplete vaccination were: living in the province of Antwerp, unemployed mother, and three or more older siblings in the household. Four years after introduction, the coverage rates were surprisingly high for a vaccine that is not fully reimbursed and not readily available in the vaccinator's fridge, which is the case for the other recommended infant vaccines.

    The prevalence of life habits may vary substantially within a country. Incidence maps of strongly related diseases can illustrate the distribution of these life style habits. In this study we explored the spatial variation in Belgium for different cancers related to alcohol and/or tobacco. From the Belgian Cancer Registry, municipality specific World Standardised incidence rates for the years 2004-2011 are used to create detailed smoothed cancer maps by subsite or histology for cancers of oral cavity, pharynx, larynx, oesophagus, liver and lung. Cancer incidence is compared both visually (from incidence maps) and with Poisson regression analysis using mortality from chronic liver disease and chronic obstructive pulmonary disease as a proxy for alcohol and tobacco prevalence, respectively. The incidence rates for oral cavity, pharyngeal and laryngeal cancer were comparable with the alcohol gradient. However, glottic cancer revealed a pattern that was more comparable with lung cancer. These two tumour types resembled more closely to the smoking pattern. Oesophageal cancer showed two patterns: squamous cell carcinoma was highly comparable with the background alcohol consumption, while adenocarcinoma was unrelated to one of our two proxies. Our approach and results are an encouraging example how data from a young cancer registry can be used in studies describing the regional cancer burden. The results can be useful for primary prevention to increase awareness for the public, authorities and health care professionals in specific subpopulations.

    In many gravel-bed rivers, bed material transfer has been interrupted or perturbed by anthropogenic activities. Currently, restoration projects are being conducted in many countries in order to re-establish bedload continuity. However, until now, few studies have provided indications of the velocity of bed material over the long-term (at least decade to century time-scale). In the context of river restoration projects (e.g. weir removal, addition of spawning gravel), these data are nevertheless crucial to predict the downstream propagation of the geomorphological and biological benefits (e.g. supply-transport equilibrium, morphological and substratum diversity). In our study, PIT-tag tracers were used in eight medium-sized gravel-bed rivers (Ardenne Region, Belgium) to propose a flow competence relationship based on specific stream power, on the one hand, and to determine the long-term virtual velocity of the bed material corresponding to the median diameter (D50) of the surface layer of riffles, on the other hand. After each flow event that exceeded the threshold for sediment entrainment, tagged particles were sought and located, even when they were buried in the subsurface layer. Afterwards, all of the data were used to estimate the virtual velocity of the bed material over the long-term using three approaches. Finally, the results were compared with long-term transport estimations based on iron slag dispersed by the rivers since the end of the middle ages.

    Gastrointestinal parasites are important infectious causes of diarrhoea in captive non-human primates (NHP). However, prevalence data of gastrointestinal parasites in zoological gardens are scarce. Therefore, a cross-sectional survey was conducted to estimate the occurrence of gastrointestinal parasites in NHP of four zoological gardens in Belgium. Between August 2004 and April 2006, 910 faecal samples were collected from 222 animals housed in 39 groups. The 31 species involved were representatives of prosimians, New World (NW) monkeys, Old World (OW) monkeys and apes. Because individual sampling was impossible, a statistical simulation was performed to estimate a sufficient sample size. All samples were microscopically examined after an acetic acid-ether concentration. Differences in host species susceptibility were examined by non-parametric tests. Entamoeba spp. (44%) and Giardia spp. (41%) were the most prevalent species. Other parasites detected were Endolimax nana (36%), Chilomastix mesnili (21%), Balantidium coli (13%), Trichuris spp. (10%), Iodamoeba bütschlii (5%) and Strongyloides spp. (5%). Parasites for which a significant difference in susceptibility at the level of host taxonomy was noted were Entamoeba spp. (p<0.001) and C. mesnili (p<0.05). Samples containing Entamoeba spp. were the most prevalent in OW monkeys (p<0.0083). Samples collected from OW monkeys contained the highest number of parasite species (p<0.0083). PMID:17656023

    This study extends the analysis of the economic returns to pre-migration human capital by examining the role of the receiving context, co-ethnic residential concentration, and post-migration investments in human capital. It uses large-scale survey data on Turkish and Moroccan immigrants in Belgium. The analysis demonstrates that regarding employment, Moroccan immigrants, that is, those originating from former French colonies receive larger returns to their origin-country education and work experience in French- vs. Dutch-speaking regions. Other than the positive interaction effect between co-ethnic residential concentration and work experience on employment, there is little evidence that co-ethnic concentration increases the returns to origin-country human capital. Speaking the host-country language facilitates economic returns to origin-country work experience. Conversely, immigrants who acquire host-country credentials and work experience receive lower returns to origin-country education and experience, suggesting that, at least among low-skilled immigrants, pre- and post-migration human capital substitute rather than complement each other.

    In 1983 the sentinel laboratory network was established because of the need to describe the epidemiological evolution of infectious diseases. During the study period of 30 years (1983-2013), microbiology laboratories reported on weekly basis the laboratory diagnosed cases for a selection of infectious diseases. This resulted in a large longitudinal laboratory based database allowing to provide trends over time and distribution by person and place. During this period, adaptations to data collection were made due to changes in diagnostic methods and public health priorities, introduction and application of digital revolution, and multiple reorganizations of the laboratories. Since the surveillance network is dynamic, it necessitates a continuous evaluation to ensure that, over time, it continues to be representative of the general epidemiological trends in the country. Secondly the aim is to examine the robustness and stability of this surveillance system. Here we demonstrated that the flexibility of the data collection methodology by the sentinel laboratory network is unique and that adaptations do not affect the capacity of the system to follow trends. Therefore, the surveillance by this network is representative of the current epidemiological situation in Belgium. To our knowledge, no such surveillance network with such a long-term follow-up and demonstrated stability for multiple infectious diseases in the general population was earlier described. Furthermore, expected trends due to the implementation of vaccination or other events were accurately detected. The collected data obtained from this network allows interesting comparisons with other national and international information sources. PMID:27571203

Blood samples (K3EDTA were collected for genotyping with Kompetitive Allele Specific PCR (n = 476. Allele and genotype frequencies were calculated in those breeds with at least 12 samples (n = 8. Hardy-Weinberg equilibrium was tested. Genetic variation was identified for 4 out of 9 disorders: mutant alleles were found in 49, 15, 3 and 2 breeds for HD, DM, EIC and NCL respectively. Additionally, mutant alleles were identified in crossbreeds for both HD and EIC. For HD, DM, EIC and NCL mutant alleles were newly discovered in 43, 13, 2 and 1 breed(s, respectively. In 9, 2 and 1 breed(s for DM, EIC and NCL respectively, the mutant allele was detected, but the respective disorder has not been reported in those breeds. For 5 disorders (HMLR, MPS VII, MG, GM1, GRMD, the mutant allele could not be identified in our population. For the other 4 disorders (HD, DM, EIC, NCL, prevalence of associated mutant alleles seems strongly breed dependent. Surprisingly, mutant alleles were found in many breeds where the disorder has not been reported to date.

  8. Statistics, gymnastics and the origins of sport science in Belgium (and Europe).

    2014-01-01

    This paper analyses the introduction of statistics in the field of gymnastics and its effect on the institutionalisation of physical education as a fully fledged academic discipline. Soon after Belgian independence, Adolphe Quetelet's research already resulted in large-scale anthropometric statistics - indeed, he developed an index that is still being used and is better known under the name of the body mass index. His insights were applied by promoters of gymnastics who wanted to make physical education more scientific. Thus, Clément Lefébure, director of the Ecole Normale de Gymnastique et d'Escrime in Brussels, set up a comparative experiment (with pre- and post-test measurements) by which he intended to show that the 'rational' method of Swedish gymnastics produced much better results than the 'empirical' method of Belgian/German Turnen. Lefébure's experiment, which was cited internationally but which was also strongly contested by opponents, was one of the factors that led to Swedish gymnastics being officially institutionalised in 1908 at the newly founded Higher Institute of Physical Education of the State University of Ghent, the first institute in the world where students could obtain a doctoral degree in physical education. Although it rested actually on very weak scientific foundations, the bastion of Swedish gymnastics built in Belgium in that pre-war period collapsed only in the 1960s. From then on, sport science could develop fully within the institutes for physical education. PMID:24624946

The model results show that the changes in impervious areas and related water displacements in and between catchments due to the installation of the wastewater treatment infrastructure severely impacted low flows, peak flows and seasonal trends. They moreover show that it is difficult, but of utmost importance, to incorporate these pressures and artificial processes in an accurate way during the development of hydrological models for urbanized catchments.

    Protection against flooding by the sea, drainage of rainwater and integrated management of groundwater and surface-water resources are key issues in low-lying coastal areas. However, under exceptional circumstances, knowledge to keep coastal areas dry and habitable can be used otherwise. Inundation for military purposes is such an example. The hydrogeology of the inundation at the Yser River, Belgium, during the Great War is studied. The inundation started in October 1914 to stop the German advance and lasted until 1918. A water balance and groundwater model are combined to derive the water balance before and during the inundation and to study the impact on the groundwater system. It is concluded that a number of hydrogeological factors contributed to the effectiveness of the inundation. Most importantly, the low-permeability subsoil facilitated loss of inundation water mainly by evaporation. Further, the normal water management strategy of the area (aimed at evacuating excess water towards the sea) was reversed to keep water between the opposing armies. However, the duration of the inundation meant a reorganization of the drainage of areas not inundated; truly an exercise in integrated water management.

    Various studies focus on professional pesticide use, whereas pressure of non-professional use on human and the environment is often neglected. In this study, an attempt was made to estimate the pressure of non-professional use of pesticides on operators, aquatic organisms and bees in Belgium based on sales figures and by using three exposure models. A classification in non-professional use was made based on type of pesticide, application method and on intensity of non-professional use. Pressure of non-professional use on operators is highest for intensive operators, caused by the use of insecticides in an aerosol spray can. Pressure of non-professional pesticides on aquatic life is mainly generated by the use of herbicides. The aerosol spray induces the highest pressure whereas the trigger application hardly affects operator and environmental exposure. The ordinary non-professional user generates most pressure on aquatic organisms. Pressure of non-professional pesticides on bees is mainly caused by the use of insecticides, especially the active substance imidacloprid in combination with the aerosol spray can application method applied by an intensive operator. In general, both total usage (kg) and pressure of pesticides decreased for the period 2005 to 2012 due to efforts made by the government and industry. The results of this study suggest to pay special attention to aerosol spray applications and the non-professional use of insecticides.

  13. Social Reform in Times of Transition. Reflections on Martin Conway’s The Sorrows of Belgium

    Nico Wouters

    2014-12-01

    Full Text Available In his book The Sorrows of Belgium Martin Conway uses the Belgian case to look at the restoration of liberal parliamentary states in Europe between 1945 and 1947. Nico Wouters’ contribution focuses on three elements brought to the fore by Conway: 1 the essential yet ambivalent role played by local government (cities and municipalities, 2 the inability to institutionalise Belgian patriotism as binder for the nation-state and finally, 3 the rift between shifts in class relations and political institutional renewal. His contribution comments on each of these elements, by means of superficial comparisons with the Netherlands.As Conway shows, Belgium’s larger cities were laboratories for new political currents that in the end strengthened centrifugal, regionalist tendencies. On the other hand, the local level as an institutional part of state organisation had a reverse effect in the shorter term. The restoration after the liberation can only be understood when one takes into account how ‘local states’ imposed a compelling framework that limited the opportunities for political renewal. As such, Wouters hypothesises that these local states help to explain in part the institutional conservatism of Belgian elites, a core-element in Conway’s book. On this point Wouters sees mostly similarities with the Netherlands. A Belgian-Dutch difference on the other hand, is that the Dutch did succeed in seamlessly combining an equally conservative post-war restoration with restarting a revitalised collective national identity. Belgium’s failure in this regard was quite evident. Although it is obvious that by 1950 such a renewal had become impossible because of the Royal Question, it is still a question of the extent to which the Belgian state still had some leeway in 1945. The third and most important point is connected to the shifts in social class relations. This concerns mutual power relations, group identities, attitudes and political strategies. The

    This study extends the analysis of the economic returns to pre-migration human capital by examining the role of the receiving context, co-ethnic residential concentration, and post-migration investments in human capital. It uses large-scale survey data on Turkish and Moroccan immigrants in Belgium. The analysis demonstrates that regarding employment, Moroccan immigrants, that is, those originating from former French colonies receive larger returns to their origin-country education and work experience in French- vs. Dutch-speaking regions. Other than the positive interaction effect between co-ethnic residential concentration and work experience on employment, there is little evidence that co-ethnic concentration increases the returns to origin-country human capital. Speaking the host-country language facilitates economic returns to origin-country work experience. Conversely, immigrants who acquire host-country credentials and work experience receive lower returns to origin-country education and experience, suggesting that, at least among low-skilled immigrants, pre- and post-migration human capital substitute rather than complement each other.

    Full Text Available The Meuse is an important rain-fed river in North-Western Europe. Nine millions of people live in its catchment splited over five countries. Projected changes in precipitation and temperature characteristics due to climate change would have significant impact on the Meuse River and its tributaries. In this study, we focus on two tributaries of the Meuse in Belgium the Lesse and the Vesdre catchments. The physically based, distributed model EPICGrid, a model which reflects water-soil-plant continuum, is driven by four sets of meteorological information. Two time slices (2020–2050 and 2070–2100 and two scenarios (wet and dry were studied. The meteorological scenarios are produced by the CCI-HYDR Perturbation Tool, a tool specially designed for the Belgian climate and taking into account a broad range of models. Water balance, high-flows and low-flows are calculated. It highlights that towards the end of the century, plants may suffer from water shortage and excess. This may lead to a decrease in evapotranspiration and clear changes in water balances. The seasoning contrast in river discharge may be strongly accentuated.

    Full Text Available The paper reveals the strategic role of CSR in two higher education institutions from Belgium and Romania - ICHEC Brussels Management School and Faculty of Economics and Business Administration Galati as institutions which influence sustainable development, by proving their implications in training students as future responsible citizens. Our main goal of this study was not to realise a comparative analysis of CSR initiatives managed by these two faculties, as we focused our attention on the emphasis of the outcomes related to the CSR projects, in the context in which they were designed in a totally different manner. ICHEC Housing Project provides to the students from ICHEC Brussels Management School the experience of intercultural openness, making them take part of a social work and be conscious of the reality in three countries from South: India, Burkina Faso and Benin. Within the CSR workshop organized by Faculty of Economics and Business Administration from Galati, in partnership with a NGO and four participants from Turkey, Bulgaria, France and Austria helps the students to achieve and develop their skills related to the tools, methods and procedures which can be used in CSR operational management. The project aims at increasing the level of implication of citizens in the process of sustainable development. We are aware that each project described in this paper could be considered as a model and replicated by other higher education institutions from worldwide.

  17. Groundwater quality assessment of one former industrial site in Belgium using a TRIAD-like approach

    International Nuclear Information System (INIS)

    Contaminated industrial sites are important sources of pollution and may result in ecotoxicological effects on terrestrial, aquatic and groundwater ecosystems. An effect-based approach to evaluate and assess pollution-induced degradation due to contaminated groundwater was carried out in this study. The new concept, referred to as 'Groundwater Quality TRIAD-like' (GwQT) approach, is adapted from classical TRIAD approaches. GwQT is based on measurements of chemical concentrations, laboratory toxicity tests and physico-chemical analyses. These components are combined in the GwQT using qualitative and quantitative (using zero to one subindices) integration approaches. The TRIAD approach is applied for the first time on groundwater from one former industrial site located in Belgium. This approach will allow the classification of sites into categories according to the degree of contaminant-induced degradation. This new concept is a starting point for groundwater characterization and is open for improvement and adjustment. - Highlights: → This study presents the first application of the TRIAD approach on groundwater system. → Groundwater Quality TRIAD-like approach is based on measurements of chemical concentrations, laboratory toxicity tests and physico-chemical analyses. → None of the three TRIAD components could reliably predict the other one. - This study presents the first application of the TRIAD approach on groundwater system. None of the TRIAD components (chemistry, physico-chemistry and ecotoxicity) could reliably predict the other one.

    To study the activity of ceftibuten, we obtained multiply-resistant isolates from approximately 20 hospitals in Belgium. Against Enterobacteriaceae, all of the tested comparative compounds were more active than cefaclor, and ceftibuten and tigemonam were the most active of the agents tested. Ceftibuten MIC50s were less than or equal to 1 microgram/ml for most enteric bacilli species and 85% of strains were susceptible (less than or equal to 8 micrograms/ml). This level of activity compared favorably to that recorded for cefaclor (less than or equal to 8 micrograms/ml), cefetamet (less than or equal to 4 micrograms/ml), and cefteram (less than or equal to 1 microgram/ml), that is, 37%, 69%, and 59%, respectively. Ceftibuten, cefetamet, cefteram, and tigemonam were highly active against isolates of Haemophilus influenzae and Neisseria gonorrhoeae. None of the comparative agents were as active as cefaclor against staphylococcal isolates. Against streptococci, cefteram was the most active, and tigemonam the least active of the agents. The MIC90s of ceftibuten for strains of Streptococcus pneumoniae and Streptococcus pyogenes were 2 micrograms/ml and 0.5 microgram/ml, respectively. Strains of Streptococcus agalactiae were resistant to both ceftibuten and tigemonam; cefaclor and cefteram inhibited 100% of isolates of this species. Strains of Enterococcus faecalis and Pseudomonas aeruginosa were consistently resistant to all of the compounds. Overall, ceftibuten exhibited potent activity against many multiply-resistant clinical isolates. PMID:1901535

    Full Text Available Methods and Objectives. To estimate infant vaccination coverage in the French-speaking region of Belgium (Wallonia and in the Brussels-Capital Region, two cross-sectional studies were performed in 2012. A face-to-face questionnaire was administered by trained investigators. The objective was to evaluate infant vaccination coverage retrospectively in 18- to 24-month-old children. These studies offered the opportunity to assess some factors influencing vaccine uptake in infants. Results and Discussion. Approximately 99% of the children had received the first dose of IPV-DTaP, 90% the fourth dose, 94% the MMR vaccine, 97% the first dose of pneumococcal vaccine, and 90% the third dose. In both regions, when fitting a logistic model, the most associated factor was attendance at maternal and child clinics (MCH. No association was observed between vaccination coverage and the mother’s level of education. For the last immunization session, where the mother was a Belgian native and when she worked more hours, child was better immunized, but only in Brussels. Conclusion. Coverage for the fourth dose of hexavalent vaccine (DTaP-IPV-HBV/Hib needs to be increased. Indeed, additional effort is needed to increase HIB and pertussis coverage rates because the herd immunity threshold for these two diseases has not been reached.

    Plants release large amounts of carbon as Volatile Organic Compounds (VOCs) into the atmosphere. These VOCs play an important role in the chemistry of the troposphere as they can be involved in the mechanisms of ozone and aerosol formation. The key mechanisms underneath biogenic VOC emissions are still not well understood, leading to large uncertainties in BVOC inventories on global and regional scales. Measurements of VOCs, ozone and micro-meteorology are conducted at the `De inslag', a 80-year old mixed pine-oak forest located in the Campine region near Antwerp, Belgium. The forest site is a level-II plot of the European Programme of Intensive Monitoring Forest Ecosystems and is part of the Carboeuro and Nitroeurope-flux research network. The site is equipped with a flux tower that reaches above the 23m canopy. A Proton Transfer Reaction Mass Spectrometer and a Fast Ozone analyser allow determining VOC and ozone fluxes by Eddy Covariance. An analytic footprint model is used to exclude non-forest fluxes. In this study, we will test the accuracy of this footprint model with anthropogenic tracers (benzene and toluene).

  1. Optimizing Natural Gas Networks through Dynamic Manifold Theory and a Decentralized Algorithm: Belgium Case Study

    2014-10-01

    Natural Gas is a major energy source in Europe, yet political instabilities have the potential to disrupt access and supply. Energy resilience is an increasingly essential construct and begins with transmission network design. This study proposes a new way of thinking about modelling natural gas flow. Rather than relying on classical economic models, this problem is cast into a time-dependent Hamiltonian dynamics discussion. Traditional Natural Gas constraints, including inelastic demand and maximum/minimum pipe flows, are portrayed as energy functions and built into the dynamics of each pipe flow. Doing so allows the constraints to be built into the dynamics of each pipeline. As time progresses in the model, natural gas flow rates find the minimum energy, thus the optimal gas flow rates. The most important result of this study is using dynamical principles to ensure the output of natural gas at demand nodes remains constant, which is important for country to country natural gas transmission. Another important step in this study is building the dynamics of each flow in a decentralized algorithm format. Decentralized regulation has solved congestion problems for internet data flow, traffic flow, epidemiology, and as demonstrated in this study can solve the problem of Natural Gas congestion. A mathematical description is provided for how decentralized regulation leads to globally optimized network flow. Furthermore, the dynamical principles and decentralized algorithm are applied to a case study of the Fluxys Belgium Natural Gas Network.

  2. Additional requirements for leak-before-break application to primary coolant piping in Belgium

    Leak-Before-Break (LBB) technology has not been applied in the first design of the seven Pressurized Water Reactors the Belgian utility is currently operating. The design basis of these plants required to consider the dynamic effects associated with the ruptures to be postulated in the high energy piping. The application of the LBB technology to the existing plants has been recently approved by the Belgian Safety Authorities but with a limitation to the primary coolant loop. LBB analysis has been initiated for the Doel 3 and Tihange 2 plants to allow the withdrawal of some of the reactor coolant pump snubbers at both plants and not reinstall some of the restraints after steam generator replacement at Doel 3. LBB analysis was also found beneficial to demonstrate the acceptability of the primary components and piping to the new conditions resulting from power uprating and stretch-out operation. LBB analysis has been subsequently performed on the primary coolant loop of the Tihange I plant and is currently being performed for the Doel 4 plant. Application of the LBB to the primary coolant loop is based in Belgium on the U.S. Nuclear Regulatory Commission requirements. However the Belgian Safety Authorities required some additional analyses and put some restrictions on the benefits of the LBB analysis to maintain the global safety of the plant at a sufficient level. This paper develops the main steps of the safety evaluation performed by the Belgian Safety Authorities for accepting the application of the LBB technology to existing plants and summarizes the requirements asked for in addition to the U.S. Nuclear Regulatory Commission rules.

    Over a 4-year period (2010-13), a survey aiming at determining the occurrence of Fusarium spp. and their relations to mycotoxins in mature grains took place in southern Belgium. The most prevalent species were F. graminearum, F. avenaceum, F. poae and F. culmorum, with large variations between years and locations. An even proportion of mating type found for F. avenaceum, F. culmorum, F. cerealis and F. tricinctum is usually a sign of ongoing sexual recombination. In contrast, an unbalanced proportion of mating type was found for F. poae and no MAT1-2 allele was present in the F. langsethiae population. Genetic chemotyping indicates a majority of deoxynivalenol (DON)-producing strains in F. culmorum (78%, all 3-ADON producers) and F. graminearum (95%, mostly 15-ADON producers), while all F. cerealis strains belong to the nivalenol (NIV) chemotype. Between 2011 and 2013, DON, NIV, enniatins (ENNs) and moniliformin (MON) were found in each field in various concentrations. By comparison, beauvericin (BEA) was scarcely detected and T-2 toxin, zearalenone and α- and β-zearalenols were never detected. Principal component analysis revealed correlations of DON with F. graminearum, ENNs and MON with F. avenaceum and NIV with F. culmorum, F. cerealis and F. poae. BEA was associated with the presence of F. tricinctum and, to a lesser extent, with the presence of F. poae. The use of genetic chemotype data revealed that DON concentrations were mostly influenced by DON-producing strains of F. graminearum and F. culmorum, whereas the concentrations of NIV were influenced by the number of NIV-producing strains of both species added to the number of F. cerealis and F. poae strains. This study emphasises the need to pay attention to less-studied Fusarium spp. for future Fusarium head blight management strategies, as they commonly co-occur in the field and are associated with a broad spectrum of mycotoxins.

    Urban areas are one of the most important human habitats; already 50% of the world's population is living there and this percentage is expected to rise to 70% by 2050. Global warming and the increasing world population will only put more pressure on the living conditions in these habitats. From a thermal comfort point of view it is clear that there is a need for sustainable urban planning that integrates the thermal behaviour of these new developments. To develop sustainable urban planning it is key to know what the influence of a new development will be on the thermal behaviour of the city. Classifying the city according to the local climate zone (LCZ) scheme can provide insights in the thermal behaviour of a city. The WUDAPT LCZ classification framework makes it possible to do so in a spatially explicit manner. This study presents an evaluation of the thermal behaviour of LCZ in three different Belgian cities (Brussels, Antwerp, Ghent) based on modelled air and surface temperature. First LCZ maps were delineated for the three cities. The maps were built based on Landsat and high resolution LiDAR images conform to the WUDAPT LCZ classification framework. Meter- resolution LiDAR images provide useful information on building height and were used to improve the LCZ maps. An accuracy assessment stage was added to confirm the validity of the maps. Secondly, the LCZ maps were used as input data for the URBCLIM model to model air and surface temperature. With the modelling results we characterized the thermal behaviour of every LCZ. In a next step the results for the different cities are compared and the generic character of the WUDAPT LCZ classification framework is evaluated. The main incentive for this study is to investigate whether LCZ maps can be used to foresee the influence of future urban growth scenario's on the thermal comfort in cities in Belgium.

  5. The Variscan belt of Northern France Southern Belgium: geodynamic implications of new palaeomagnetic data

    2000-09-01

    Palaeomagnetic investigations were carried out in Devonian-early Carboniferous rocks of the Variscan foreland chain of Northern France-Southern Belgium in order to reveal the origin of its arcuate shape. The Brabant Parautochthon was sampled in the Boulonnais (near Calais) and near Tournai, while the Ardenne Allochthon was sampled near Maubeuge and in the Givet area. All the sampled localities yielded characteristic remanent magnetization as a result of stepwise demagnetization and component analysis. Fold or tilt tests were possible for three localities, with negative results indicating pervasive remagnetization. The tectonic position was sub-horizontal at two localities, while the tilt was monoclinal for the rest. Therefore, the acquisition time of the magnetic signals was estimated by comparing the palaeolatitude computed from each magnetic component to the palaeolatitudes of Variscan Europe calculated after Van der Voo (1993). Three components showing: A, a southern B, a near-Equatorial, and C, a northern palaeolatitude are recognized from our data. Since a pre-Variscan age of component A (observed only in Boulonnais, at 10 sites) is not supported by data, it is assigned to an early phase of deformation. Component B (16 sites) was acquired during the peak of the Variscan tectonics (late Westphalian), while component C (five sites) originated during Permian times. Regardless of the palaeolatitudes, declinations fall between 190 and 210°, thus being conformable with the declinations expected for Variscan Europe. The declinations show no correlation with the arcuate shape of the belt, neither are they different in the Paraauthochthon and in the Allochthon, nor in the different components. Arc formation by moulding of the Allochthon on the Brabant Parautochthon is, therefore, not supported by these data, since this mechanism requires substantial (opposed) rotations on both wings of the arc. The available palaeomagnetic data are conformable with a pre-formed arc

    On 3 December 1828 at half past six in the evening, the border region between Belgium and Germany was stricken by a moderate earthquake. Up to now, the available information on this event has been essentially provided by a few contemporaneous scientific studies. To better evaluate its impact, location and magnitude, we have searched for new original historical reports. We collected 57 additional witness testimonies, which complete those previously collected about the earthquake effects. Among the testimonies, we also retrieved a questionnaire sent by the Prussian government to local authorities with the purpose of quickly obtaining information on the earthquake effects in the western part of the kingdom of Prussia. This inquiry is the oldest of its kind that has been discovered to date in this part of Europe, suggesting a rare concern by a national authority about the seismic hazard, and prefiguring the seismic inquiries that scientific institutions use today. The analysis of these new data made it possible to evaluate the intensity in 50 cities out of the 75 where the earthquake was observed. From these intensity data, we determine that the epicentre was in the Hautes-Fagnes region [lat. 50.38°N/long. 6.19°E ± 30 km] where moderate damage, corresponding to EMS-98 intensity VI-VII, was observed. At large distances, the earthquake was felt as far as Düsseldorf to the north, Brussels to the west, Metz to the south and Wiesbaden to the east. These distances correspond to a perceptibility radius of about 150 km. The magnitude of this earthquake is evaluated to be ML = 4.7 (-0.2/+0.5) and MW = 4.2 (+0.4/-0.2).

  7. Determinants of the geographic distribution of Puumala virus and Lyme borreliosis infections in Belgium

    2007-05-01

    Full Text Available Abstract Background Vector-borne and zoonotic diseases generally display clear spatial patterns due to different space-dependent factors. Land cover and land use influence disease transmission by controlling both the spatial distribution of vectors or hosts, and the probability of contact with susceptible human populations. The objective of this study was to combine environmental and socio-economic factors to explain the spatial distribution of two emerging human diseases in Belgium, Puumala virus (PUUV and Lyme borreliosis. Municipalities were taken as units of analysis. Results Negative binomial regressions including a correction for spatial endogeneity show that the spatial distribution of PUUV and Lyme borreliosis infections are associated with a combination of factors linked to the vector and host populations, to human behaviours, and to landscape attributes. Both diseases are associated with the presence of forests, which are the preferred habitat for vector or host populations. The PUUV infection risk is higher in remote forest areas, where the level of urbanisation is low, and among low-income populations. The Lyme borreliosis transmission risk is higher in mixed landscapes with forests and spatially dispersed houses, mostly in wealthy peri-urban areas. The spatial dependence resulting from a combination of endogenous and exogenous processes could be accounted for in the model on PUUV but not for Lyme borreliosis. Conclusion A large part of the spatial variation in disease risk can be explained by environmental and socio-economic factors. The two diseases not only are most prevalent in different regions but also affect different groups of people. Combining these two criteria may increase the efficiency of information campaigns through appropriate targeting.

  8. Effect of excavation induced fractures on radionuclide migration through the boom clay (Belgium)

    International Nuclear Information System (INIS)

    In Belgium, the Boom Clay at a depth of 200 m below surface is being evaluated as a potential host formation for the disposal of high-level nuclear waste. In order to investigate this option, an underground research facility composed of two access shafts and a 200 m long gallery was excavated in the Boom Clay for research purposes (HADES-URF). Around the gallery, excavation induced fractures are observed. The majority of these fractures are approximately parallel planes with an average spacing of around 70 cm, a strike approximately perpendicular to the tunnel axis and a dip between 30 and 70 degrees. fracturing and self-sealing processes in Boom (and Opalinus) Clay were studied in the EC SELFRAC project (EC contract FIKW-CT2001-00182). The research performed in the framework of this project shows that the excavation induced fractures around the connecting gallery are limited to a zone of 1 m. This gallery was excavated using an industrial technique and with minimal radial convergence. Moreover self-sealing processes, which will further limit the influence of these fractures, have clearly been demonstrated in laboratory and in-situ experiments. The potential effect of these excavation induced fractures on the radionuclide migration through the clay is investigated in this study under the conservative assumption that no self-sealing occurs. A hydrogeological model of the clay is built with a radionuclide source in the middle of the clay surrounded by different fracture configurations. The radionuclide flux through the upper and lower boundaries of the clay into the surrounding aquifers is calculated and compared for different fracture configurations. (authors)

    Full Text Available Abstract Background Mortality and morbidity are hardly documented in the white veal industry, despite high levels of antimicrobial drug use and resistance. The objective of the present study was to determine the causes and epidemiology of morbidity and mortality in dairy, beef and crossbred white veal production. A total of 5853 calves, housed in 15 production cohorts, were followed during one production cycle. Causes of mortality were determined by necropsy. Morbidity was daily recorded by the producers. Results The total mortality risk was 5,3% and was significantly higher in beef veal production compared to dairy or crossbreds. The main causes of mortality were pneumonia (1.3% of the calves at risk, ruminal disorders (0.7%, idiopathic peritonitis (0.5%, enterotoxaemia (0.5% and enteritis (0.4%. Belgian Blue beef calves were more likely to die from pneumonia, enterotoxaemia and arthritis. Detection of bovine viral diarrhea virus at necropsy was associated with chronic pneumonia and pleuritis. Of the calves, 25.4% was treated individually and the morbidity rate was 1.66 cases per 1000 calf days at risk. The incidence rate of respiratory disease, diarrhea, arthritis and otitis was 0.95, 0.30, 0.11 and 0.07 cases per 1000 calf days at risk respectively. Morbidity peaked in the first three weeks after arrival and gradually declined towards the end of the production cycle. Conclusions The present study provided insights into the causes and epidemiology of morbidity and mortality in white veal calves in Belgium, housed in the most frequent housing system in Europe. The necropsy findings, identified risk periods and differences between production systems can guide both veterinarians and producers towards the most profitable and ethical preventive and therapeutic protocols.

    We conducted a survey to determine how two professional sectors in Belgium, horticulture professionals and nature reserve managers (those directly involved in conservation), view the issues associated with invasive plant species. We developed and utilized a questionnaire that addressed the themes of awareness, concept and use of language, availability of information, impacts and, finally, control and available solutions. Using co-inertia analyses, we tested to what extent the perception of invasive alien species (IAS) was dependent upon the perception of Nature in general. Only forty-two percent of respondent horticulture professionals and eighty-two percent of nature reserve managers had a general knowledge of IAS. Many individuals in both target groups nonetheless had an accurate understanding of the scientific issues. Our results therefore suggest that the manner in which individuals within the two groups view, or perceive, the IAS issue was more the result of lack of information than simply biased perceptions of target groups. Though IAS perceptions by the two groups diverged, they were on par with how they viewed Nature in general. The descriptions of IAS by participants converged with the ideas and concepts frequently found in the scientific literature. Both managers and horticulture professionals expressed a strong willingness to participate in programs designed to prevent the spread of, and damage caused by, IAS. Despite this, the continued commercial availability of many invasive species highlighted the necessity to use both mandatory and voluntary approaches to reduce their re-introduction and spread. The results of this study provide stakeholders and conservation managers with practical information on which communication and management strategies can be based.

  11. Variability in the hydraulic conductivity of the Boom clay in the Campine Basin, NE-Belgium

    International Nuclear Information System (INIS)

    Document available in extended abstract form only. In the framework the Belgian research program on the long term management of high-level and/or long-lived radioactive waste coordinated by ONDRAF/NIRAS, the Boom Clay has been investigated for more than 30 years as a candidate host formation for the disposal of high-level and long-lived radioactive waste in Belgium. The very low hydraulic conductivity (on the order of 10-12 m/s) in combination with limited hydraulic gradients over the host formation (0.02 ∼ 0.04 m/m) results in water flow in the Boom Formation being negligible and diffusion the dominant transport mechanism. The assessment of the long-term barrier function of the host clay formation in the framework of radioactive waste disposal requires rigorous quantitative characterization of key formation properties such as the hydraulic conductivity (K). Hydraulic conductivities of Boom Clay measured through various testing techniques in the laboratory, i.e. tracer percolation experiments, constant head permeameter experiments and isostatic experiments, exhibit similar K values in the order of 10-12 m/s. Based on a large set of test samples, the impact of sample scale, hydraulic gradient range adopted in the tests, stress controlled methods and pre-existing fissures in the sample on the K value is shown to be quite limited. In situ measurements obtained from both several-centimetre long piezometer filters and percolation into a 7-metre long gallery and 21-meter long shaft at the HADES underground research facility yield K values that are very similar to values measured in the laboratory on samples of a few centimetres. This indicates that the K measurements for the Boom Clay obtained through various techniques are very consistent. K values measured on a centimetre-scale are also representative at the metre-scale, which is often the size of grid cells used in numerical simulations for long-term safety assessments. Spatial analysis of K values across the Boom

    We identified a novel plasmid-mediated colistin-resistance gene in porcine and bovine colistin-resistant Escherichia coli that did not contain mcr-1. The gene, termed mcr-2, a 1,617 bp phosphoethanolamine transferase harboured on an IncX4 plasmid, has 76.7% nucleotide identity to mcr-1. Prevalence of mcr-2 in porcine colistin-resistant E. coli (11/53) in Belgium was higher than that of mcr-1 (7/53). These data call for an immediate introduction of mcr-2 screening in ongoing molecular epidemiological surveillance of colistin-resistant Gram-negative pathogens. PMID:27416987

  18. Estimating Soil Organic Carbon stocks and uncertainties for the National inventory Report - a study case in Southern Belgium

    2016-04-01

    As many other countries, Belgium complies with Annex I of the United Nations Framework Convention on Climate Change (UNFCCC). Belgium thus reports its annual greenhouse gas emissions in its national inventory report (NIR), with a distinction between emissions/sequestration in cropland and grassland (EU decision 529/2013). The CO2 fluxes are then based on changes in SOC stocks computed for each of these two types of landuse. These stocks are specified for each of the agricultural regions which correspond to areas with similar agricultural practices (rotations and/or livestock) and yield potentials. For Southern Belgium (Wallonia) consisting of ten agricultural regions, the Soil Monitoring Network (SMN) 'CARBOSOL' has been developed this last decade to survey the state of agricultural soils by quantifying SOC stocks and their evolution in a reasonable number of locations complying with the time and funds allocated. Unfortunately, the 592 points of the CARBOSOL network do not allow a representative and a sound estimation of SOC stocks and its uncertainties for the 20 possible combinations of land use/agricultural regions. Moreover, the SMN CARBIOSOL is based on a legacy database following a convenience scheme sampling strategy rather than a statistical scheme defined by design-based or model-based strategies. Here, we aim to both quantify SOC budgets (i.e., How much?) and spatialize SOC stocks (i.e., Where?) at regional scale (Southern Belgium) based on data from the SMN described above. To this end, we developed a computation procedure based on Digital Soil Mapping techniques and stochastic simulations (Monte-Carlo) allowing the estimation of multiple (10,000) independent spatialized datasets. This procedure accounts for the uncertainties associated to estimations of both i) SOC stock at the pixelscale and ii) parameters of the models. Based on these 10,000 individual realizations of the spatial model, mean SOC stocks and confidence intervals can be then computed at

  2. Long-term DOC-leaching from a temperate Scots pine forest (Brasschaat, Belgium).

    2009-04-01

    The carbon and water balance of terrestrial ecosystems are tightly coupled. Part of the assimilated carbon is leached from the ecosystem as dissolved organic carbon (DOC). These DOC-fluxes from the ecosystem are highly uncertain and are not incorporated in most process-based models. Therefore the focus of this study is to determine the drivers of the interannual and seasonal variability of the DOC-leaching. The study site is located 20km NE of Antwerp, near Brasschaat (Belgium) and consists of an 80-year-old even aged Scots pine (Pinus sylvestris L.) stand, which belongs to a larger mixed coniferous/deciduous forest and it is part of the ICP-II and Fluxnet/CarboEurope-IP networks since 1997. We simulated the different components of the water balance (transpiration, soil evaporation canopy evaporation, soil water content, runoff and leaching) with a combination of field measurements (sap flow, eddy covariance, TDR's) and the ORCHIDEE model. DOC concentrations were measured monthly in the trough fall and at four depths in the soil from the year 2000 onwards. Here we report estimates of DOC-leaching for a six year period (2000-2006) and assess its importance in the total carbon balance of the ecosystem. Results indicate that on average 10% of yearly NEE (as measured with eddy covariance measurements) is lost as DOC in the soil. We further looked at the drivers responsible for seasonal and interannual variation of the DOC-leaching. Logically, water leaching is the main driver of the DOC-leaching, for both the seasonal and the interannual variability. The remaining variation in the DOC leaching is affected by soil temperature and pH. DOC concentrations are highest in the upper soil layer and gradually decrease with depth. This could be explained by part of the DOC being respired as CO2 and part being retained in the soil matrix by Al and Fe-oxides adsorption. Future climate scenarios predict drier summer periods and more precipitation during the winter for the north

  3. Achievements and projects in Belgium in the field of reactor shielding

    International Nuclear Information System (INIS)

    Four reactors are in operation in Belgium: the BR-1 and BR-2 which are research and materials testing reactors, the BR-3 which has a power output of 11 MW(e) and the BR-02 which is the nuclear mock-up of the BR-2. In 1965 the BR-3 will be operating on the spectral-shift principle. The VENUS reactor, the critical mock-up of the future BR-3 core, should commence operation in April 1964. By the end of 1964, the University of Ghent will have at its disposal a swimming-pool type reactor. The fast reactors MASURCA and HARMONIE were studied on behalf of the French Atomic Energy Commission and EURATOM. Most of these reactors raise no shielding problems other than the conventional ones. The VULCAIN prototype shield will be designed in accordance with the specifications characteristic of naval reactors, in which an optimization of volume, weight and cost is of primary interest. Study of these problems has begun. The radiation damage of the BR-3 pressure vessel is a problem when equipped with the future spectral-shift core. The level and spectrum of neutron irradiation will be experimentally determined in the VENUS facility. All shielding studies were carried out by conventional methods and in no case was any research project, either experimental or theoretical, undertaken along these lines. Works were accepted on the basis of their practical utility and no specific experiment for the verification of the theoretical studies was ever carried out. Among the main theoretical problems encountered in shielding design, the following should be cited: Gamma and neutron attenuation along straight and stepped ducts; Back-scattering of gammas and neutrons from air (skyshine), solid and liquid materials, and shielding of the reflected radiations; Gamma and neutron propagation at long distance in air; Capture gamma spectra as a function of the energy of the incident neutron; and Gamma radiations from neutron inelastic scattering.

    Full Text Available Abstract Background This study compares prevalence and types of medical end-of-life decisions between the Dutch-speaking and French-speaking communities of Belgium. This is the first nationwide study that can make these comparisons and the first measurement after implementation of the euthanasia law (2002. Methods We performed a mortality follow-back study in 2005–2006. Data were collected via the nationwide Sentinel Network of General Practitioners, an epidemiological surveillance system representative of all Belgian GPs. Weekly, all GPs reported the medical end-of-life decisions among all non-sudden deaths of patients in their practice. We compared the northern Dutch-speaking (60% and southern French-speaking communities (40% controlling for population differences. Results We analysed 1690 non-sudden deaths. An end-of-life decision with possible life-shortening effect was made in 50% of patients in the Dutch-speaking community and 41% of patients in the French-speaking community (OR 1.4; 95%CI, 1.2 to 1.8. Continuous deep sedation until death occurred in 8% and 15% respectively (OR 0.5; 95%CI, 0.4 to 0.7. Community differences regarding the prevalence of euthanasia or physician-assisted suicide were not significant. Community differences were more present among home/care home than among hospital deaths: non-treatment decisions with explicit life-shortening intention were made more often in the Dutch-speaking than in the French-speaking community settings (OR 2.2; 95%CI, 1.2 to 3.9; while continuous deep sedation occurred less often in the Dutch-speaking community settings (OR 0.5; 95%CI, 0.3 to 0.9. Conclusion Even though legal and general healthcare systems are the same for the whole country, there are considerable variations between the communities in type and prevalence of certain end-of-life decisions, even after controlling for population differences.

    1999-07-01

    Both Recent and fossil tufa deposits from Belgium were studied by petrographical and geochemical means. Study of the Recent deposits provides information on precipitation conditions and on possible present-day biological influences of organisms on tufa precipitation. Comparative petrographical and geochemical investigations of both Recent and fossil deposits give information about diagenetic modifications. The Recent deposits form within small rivers, where they display two macro-types, i.e. precipitates on organic substrates (plants, mosses, algae, cyanobacteria) and laminated carbonate crusts. The latter occur on the river bed or on different substrates (limestone rocks, snail shells, artificial glass and limestone plates). Characteristic petrographical features are, on the one hand, horizontal laminations within the carbonate crusts, which relate to seasonal growth patterns of the present cyanobacteria and on the other hand, the close association between the organic matter and carbonate precipitates in the actively forming deposits. Due to encrustation in growth position, the organic structures determine the overall structure of the precipitates. Characteristic crystal morphologies (pseudo-hexagonal crystals and penta-dodecahedral crystals on mosses and algae) and specific features (e.g. micritic cyanobacterial bushes) show possible direct influence of the organisms on calcite precipitation. The stable carbon isotope signature of the Recent deposits with a mean δ 13C value of about -11.05‰ PDB points to a mixture of three possible CO 2 sources, i.e. atmospheric-related CO 2, recycled marine CO 2 and biological CO 2. The studied fossil deposits consist of granular detrital tufa and porous cascade tufa with precipitates on organic substrates and laminated carbonate crusts, which show similar characteristics to the macrotypes found in the Recent deposits. However, there are differences between Recent and paleo-deposits that can be attributed to diagenetic

    Residues of brominated diphenylethers (PBDEs), organochlorinated pesticides (OCPs) and polychlorinated biphenyls (PCBs) were measured in 40 eggs of little owls (Athene noctua), a terrestrial top predator from Belgium. The major organohalogens detected were PCBs (median 2,600 ng/g lipid, range 790-23000 ng/g lipid). PCB 153,138/163, 170, 180 and 187 were the predominant congeners and constituted 71% of total sum PCBs. PBDEs were measurable in all samples, but their concentrations were much lower than for PCBs, with a range from 29-572 ng/g lipid (median 108 ng/g lipid). The most prevalent PBDE congeners in little owl egg samples were BDE 47, 99 and 153. This profile differs from the profile in marine bird species, for which BDE 47 was the dominant congener, indicating that terrestrial birds may be more exposed to higher brominated BDE congeners than marine birds. The fully brominated BDE 209 could be detected in one egg sample (17 ng/g lipid), suggesting that higher brominated BDEs may accumulate in terrestrial food chains. Brominated biphenyl (BB) 153 was determined in all egg samples, with levels ranging from 0.6 to 5.6 ng/g lipid (median 1.3 ng/g lipid). Additionally, hexabromocyclododecane (HBCD) could be identified and quantified in only two eggs at levels of 20 and 50 ng/g lipid. OCPs were present at low concentrations, suggesting a rather low contamination of the sampled environment with OCPs (median concentrations of sum DDTs: 826 ng/g lipid, sum chlordanes: 1,016 ng/g lipid, sum HCHs: 273 ng/g lipid). Hexachlorobenzene (HCB) and octachlorostyrene (OCS) were also found at low median levels of 134 and 3.4 ng/g lipid, respectively. Concentrations of most analytes were significantly higher in eggs collected from deserted nests in comparison to addled (unhatched) eggs, while eggshell thickness did not differ between deserted and addled eggs. No significant correlations were found between eggshell thickness and the analysed organohalogens. - PBDEs are measurable

  7. Climate change impacts on groundwater resources: modelled deficits in a chalky aquifer, Geer basin, Belgium

    Brouyère, Serge; Carabin, Guy; Dassargues, Alain

    An integrated hydrological model (MOHISE) was developed in order to study the impact of climate change on the hydrological cycle in representative water basins in Belgium. This model considers most hydrological processes in a physically consistent way, more particularly groundwater flows which are modelled using a spatially distributed, finite-element approach. Thanks to this accurate numerical tool, after detailed calibration and validation, quantitative interpretations can be drawn from the groundwater model results. Considering IPCC climate change scenarios, the integrated approach was applied to evaluate the impact of climate change on the water cycle in the Geer basin in Belgium. The groundwater model is described in detail, and results are discussed in terms of climate change impact on the evolution of groundwater levels and groundwater reserves. From the modelling application on the Geer basin, it appears that, on a pluri-annual basis, most tested scenarios predict a decrease in groundwater levels and reserves in relation to variations in climatic conditions. However, for this aquifer, the tested scenarios show no enhancement of the seasonal changes in groundwater levels. Un modèle hydrologique intégré (MOHISE) a été développé afin d'étudier l'impact du changement climatique sur le cycle hydrologique de bassins versants représentatifs de Belgique. Ce modèle prend en compte tous les processus hydrologiques d'une manière physiquement consistante, plus particulièrement les écoulements souterrains qui sont modélisés par une approche spatialement distribuée aux éléments finis. Grâce à cet outil numérique précis, après une calibration et une validation détaillées, des interprétations quantitatives peuvent être réalisées à partir des résultats du modèle de nappe. Considérant des scénarios de changements climatiques de l'IPCC, l'approche intégrée a été appliquée pour évaluer l'impact du changement climatique sur le cycle de l

    This study aimed at estimating, in a prospective scenario, the potential economic impact of a possible epidemic of WNV infection in Belgium, based on 2012 values for the equine and human health sectors, in order to increase preparedness and help decision-makers. Modelling of risk areas, based on the habitat suitable for Culex pipiens, the main vector of the virus, allowed us to determine equine and human populations at risk. Characteristics of the different clinical forms of the disease based on past epidemics in Europe allowed morbidity among horses and humans to be estimated. The main costs for the equine sector were vaccination and replacement value of dead or euthanised horses. The choice of the vaccination strategy would have important consequences in terms of cost. Vaccination of the country's whole population of horses, based on a worst-case scenario, would cost more than EUR 30 million; for areas at risk, the cost would be around EUR 16-17 million. Regarding the impact on human health, short-term costs and socio-economic losses were estimated for patients who developed the neuroinvasive form of the disease, as no vaccine is available yet for humans. Hospital charges of around EUR 3,600 for a case of West Nile neuroinvasive disease and EUR 4,500 for a case of acute flaccid paralysis would be the major financial consequence of an epidemic of West Nile virus infection in humans in Belgium.

    Full Text Available In 2011, a large outbreak of infections caused by Shiga toxin-producing Escherichia coli (STEC O104:H4 occurred in Germany. This exceptionally virulent strain combined virulence factors of enteroaggregative E. coli (EAggEC and STEC. After the outbreak only a few sporadic cases of infection with this rare serotype were reported, most of which were related to travel to the Middle East or North Africa. Here we describe two cases of enteroaggregative STEC (Agg-STEC O104:H4 infection that occurred in Belgium in 2012 and 2013 respectively. In both cases travel in a Mediterranean country preceded the infection. The first strain was isolated from the stool of a 42-year-old woman presenting bloody diarrhoea, who had travelled to Tunisia the week before. The second case involves a 14-year-old girl who, upon her return from Turkey to Belgium, suffered from an episode of bloody diarrhoea and haemolytic uraemic syndrome. Extended typing of the isolates with pulsed field gel electrophoresis revealed that the strains were closely related, though not exactly the same as the 2011 outbreak strain. This report supports the previously made hypothesis that Agg-STEC has a human reservoir and might be imported by travellers coming from an area where the pathogen is endemic. Furthermore, it emphasizes the concern that these bacteria may cause future outbreaks as evenly virulent O104:H4 isolates seem to be widespread.

    The chemical composition, as determined by electron probe X-ray microanalysis of a series of ca. 100 archaeological glass fragments, excavated at the Raversijde site (Belgium) is discussed. In the 15th-16th century, Raversijde was a flourishing fishermen town located on the shore of the North Sea, close to the city of Ostend. As a consequence of several battles that were fought in its vicinity, the site was abandoned in the 16th century and was not occupied since then. It is one of the rare archaeological sites in Europe that contains a significant amount of information on the daily life inside a small but affluent medieval community. A comparison of the chemical composition of fragments of vessels and window glass encountered in Raversijde to those found in urban centres in Belgium and to literature date on German and French archaeological finds shows that glass made with wood ash dominates. Usually, it concerns artifacts with a predominantly utilitarian use. A few objects made with sodic (i.e., Na-rich) glass were also encountered, likely to have been imported from Venice during the 15th century or in later periods from an urban centre such as Antwerp, where Facon-de-Venice glass manufacturing activities were established near the start of the 16th century.

    Coastal ecosystems have been attributed the potential to store large amounts of organic carbon (OC), often referred to as blue carbon, of which a considerable amount is stored in tidal marsh soils. Large uncertainties still exist with respect to the amount and controlling factors of soil organic carbon (SOC) stored in these ecosystems. Moreover, most research has focused on SOC dynamics of saltmarshes, while brackish and freshwater marshes are often even more productive and thus receive even larger organic carbon inputs. Therefore, in this study the OC dynamics of tidal marsh soils along an estuarine gradient are studied in order to contribute to our knowledge of 1) the stocks, 2) the controlling factors and 3) the fate of SOC in tidal marshes with different environmental characteristics. This research thus contributes to a better understanding of the potential of coastal environments to store organic carbon under future climatic changes. Soil and vegetation samples are collected in tidal salt-, brackish- and freshwater marshes in the Scheldt estuary (Belgium - The Netherlands). At each tidal marsh, three replicate soil cores up to 1.5m depth in 0.03m increments are collected at locations with both a low and a high elevation. These cores are analyzed for OC, stable C and N isotopes, bulk density and texture. Incubation experiments of topsoil samples were conducted and both aboveground and belowground biomass were collected. The results show that SOC stocks (range: 13,5 - 35,4 kg OC m-2), standing biomass (range: 2000 - 7930 g DW m-2) and potential soil respiration of CO2 (range: 0,03 - 0,12 % per unit OC per day) decrease with increasing salinity. This shows that both the amount of OC from local macrophytes and the quality of the organic matter are important factors controlling the SOC stocks. In addition, based on the analysis of stable C and N isotopes, it appears that when a significant fraction of SOC is derived from local macrophytes, higher SOC stocks are

    From February 2010 to February 2011 PM10 aerosol samples were simultaneously taken every 4th day at 7 monitoring sites in Flanders, Belgium. Two of the sites (i.e., Borgerhout and Gent) were urban background sites; one (i.e., Mechelen) a suburban background site, and the other four (i.e., Hamme, Lier, Retie, and Houtem) rural background sites, whereby Hamme and Lier were expected to be particularly impacted by biomass burning. The samplings were done for 24h and 47-mm diameter Pallflex® Tissuquartz™ 2500 QAT-UP filters were used. After sampling the PM10 mass concentration was determined by weighing; organic and elemental carbon (OC and EC) were measured by thermal-optical transmission analysis and the wood burning tracers levoglucosan, mannosan, and galactosan were determined by means of gas chromatography/mass spectrometry. The atmospheric concentrations of levoglucosan and the other two monosaccharide anhydrides showed a very clear seasonal variation at each site, with highest levels in winter, followed by autumn, spring, and summer. The levoglucosan levels for 5 of our 7 sites (i.e., Retie, Lier, Mechelen, Borgerhout, and Gent) were very highly correlated with each other (all between site correlation coefficients r>0.9, except for one value of 0.86) and the levels in the parallel samples of these 5 sites were similar, indicating that wood burning at these 5 sites was a regional phenomenon and that it was taking place in many individual houses on similar occasions (e.g., on cold days, weekends or holidays). The levoglucosan levels at Houtem and the correlation coefficients of the 5 sites with Houtem were lower, which is explained by the fact that the latter site is at less than 20 km from the North Sea so that the air there is often diluted by rather clean westerly maritime air. A peculiar behavior was seen for Hamme, with on many occasions very high levoglucosan levels, which was attributed to the fact that there is wood burning going on in several houses

    The Walloon Region in Belgium played a leading role in the world economy and in the industrial sciences and engineering since the 19th century. Several relicts, such as important industrial buildings or sites, are spread over a large area and are still dominating the current landscape. Some of these remnants are preserved as monuments, representing the industrial, cultural and ecological transition of the region during the last two centuries. Since 2012, UNESCO recognized the importance of four of the best preserved 19th and 20th century coal mining sites and classified them as World Heritage ("Major Mining Sites of Wallonia", Le Grand-Hornu, Bois-du- Luc, Le Bois du Cazier and Blegny Mine). The four recognised mining sites together form a strip of about 170 km long, containing important examples of the so-called 'neo classical architecture' from the early periods of the industrial era in continental Europe. Motivated by this recognition and by the huge touristic and educational potential of the sites, a partnership between the Walloon government and Ghent University was organized. In this first stage, the collaboration focuses on the site of Bois-du-Luc in the municipality of La Louvière, containing a large series of dwellings, several equipments built between 1853 and 1923 by the Société des Charbonnages du Bois-du-Luc, workshops and heaps. Consisting of numerous buildings dating back to the period between 1838 and 1923, this site is one of Europe's oldest collieries. The collaboration between the Walloon government and Ghent University - Department of Geography fits in the hands-on training which students in land surveying and geomatics receive during their Bachelor studies. For the students it is very interesting that their practical exercises are not limited to the university campus, but that they are involved in a real measurement campaign. The project consists of a series of intensive land surveying campaigns, resulting in highly detailed and accurate

    Sedimentary basins in Northwest Europe have significant potential for low to medium enthalpy, deep geothermal energy resources. These resources are currently assessed using standard exploration techniques (seismic investigations followed by drilling of a borehole). This has enabled identification of geothermal resources but such techniques are extremely costly. The high cost of exploration remains one of the main barriers to geothermal project development due to the lack of capital in the geothermal industry. We will test the possibility of using the Electro-Magnetic (EM) methods to aid identification of geothermal resources in conjunction with more traditional exploration methods. An EM campaign could cost a third of a seismic campaign and is also often a passive technology, resulting in smaller environmental impacts than seismic surveys or drilling. EM methods image changes in the resistivity of the earth's sub-surface using natural or induced frequency dependant variations of electric and magnetic fields. Changes in resistivity can be interpreted as representing different subsurface properties including changes in rock type, chemistry, temperature and/or hydraulic transmissivity. While EM techniques have proven to be useful in geothermal exploration in high enthalpy areas in the last 2-3 years only a handful of studies assess their applicability in low enthalpy sedimentary basins. Challenges include identifying which sub-surface features cause changes in electrical resistivity as low enthalpy reservoirs are unlikely to exhibit the hydrothermally altered clay layer above the geothermal aquifer that is typical for high enthalpy reservoirs. Yet a principal challenge is likely to be the high levels of industrialisation in the areas of interest. Infrastructure such as train tracks and power cables can create a high level of background noise that can obfuscate the relevant signal. We present our plans for an EM campaign in the Flemish region of Belgium. Field

    The Campine Basin, NE Belgium, is situated between the uplifting Ardennes Massif and rapidly subsiding Roer Valley Graben. It contains a thick series of marine, estuarine and continental Neogene and Quaternary sediments, locally more than 300 m. As a result of relief inversion during the Quaternary, the Campine Plateau is nowadays a distinct morphological feature in this basin. Its surface elevation dips from 100 m in the south to 30 m in the north over a distance of about 60 km, which is the result of differential uplift. The Campine Plateau is covered by Early and Middle Pleistocene erosion-resistant fluvial sediments from the Rhine and Meuse and can thus be regarded as a fluvial terrace. The age of deposition and time of abandonment of the terrace have not yet been resolved by direct numerical dating. In this study, we apply the cosmogenic radionuclide (CRN) profiling technique that, in ideal circumstances, allows one to constrain the exposure age, burial age and amount of post-depositional erosion of the landform. Samples were taken from a 3.5 m deep cross-section in coarse river sands that were deposited by the river Rhine, and now situated at an altitude of about 50 m (a.s.l.). Nine of them were prepared for CRN measurements according to state-of-the-art techniques. The in-situ 10Be concentration of the samples was determined using accelerator mass spectrometry (ETH, Zurich). The in-situ 10Be concentrations are 1.5x10e5 atoms/g for the uppermost sample (at 0.3 m depth) and 0.9x10e5 at/g for the lowermost sample (at 3.1 m depth), yielding an estimated 0.6x10e5 at/g of radionuclide accumulation following sediment deposition. Using forward modelling, we solved for the exposure duration and erosion rate that best fit the measured in-situ 10Be depth profile data, nuclide inheritance and their associated analytical uncertainties. Model optimisation is here based on the sum of chi-squared between the measured and modelled 10Be concentrations. When taking previous

Based on these results, the 8-item short form is recommended for use with Dutch-speaking adolescents when administration of the full form seems less advisable due to time constraints. Suggestions for potential use of the short form and for future research on its reliability and validity are outlined.

    Previous research has indicated that opposition toward lesbian, gay, bisexual, and trangender (LGBT) rights remains prevalent among Western populations. In this article, we investigate the determinants of anti-gay attitudes among adolescents in two liberal democracies, Belgium (n = 6,330) and Canada (n = 3,334). The analysis indicates that hostile feelings toward LGBT rights are particularly widespread among boys, while the effects of socioeconomic status and parental education remain limited. Various religious denominations proved to have a strong and significant negative impact on tolerance, with especially high scores for Islam. Religious practice, too, contributes to a negative attitude toward LGBT rights. The consequences of these findings with regard to tolerance for gay rights among Islamic youth in Western democracies are discussed. PMID:20391000

    Wallonia (the region covering southern Belgium) is committed to making a significant increase in its wind-powered electricity production capacity by 2010. Therefore, a decision support system designed to evaluate and map environmental and landscape constraints fundamental to the building of wind farms was developed for the whole Walloon Region (17,000 km{sup 2}). This system is a geodatabase using 40 criteria (landscape or environmental) corresponding to three constraint levels (exclusion, highly sensitive and sensitive). This geodatabase also has analysis functions developed in the ArcGIS 9 software environment that are used to update the overall constraints map, to analyse sensitivity with respect to constraint criteria-defining parameters as well as to perform full diagnostic studies on wind farm projects.

    2002-01-01

    This article focuses on consumer reactions during and after the Coca-Cola crisis of June 1999 in Belgium. The research tests for associations between the personality trait "emotional stability," attitude toward the brand, and self-reported behavior. Cross-sectional data are collected from a sample of Coca-Cola drinkers between 19 and 22 years old. The data are analyzed through the specification and estimation of a structural equation model and ANOVA. A direct and positive effect of attitude toward the brand on the behavioral response is found. No direct effect of emotional stability on behavior is revealed. However, indirect effects of personality mediated by attitude are discovered. Further, emotional stability is found to correlate negatively with importance attached to information during the crisis. Fast and transparent communication with specific attention to lower emotional stability groups, as well as the inclusion of personality and attitude measurements in future health and food safety studies, are recommended.

    The placoderm fauna of the upper Famennian tetrapod-bearing locality of Strud, Belgium, includes the antiarch Grossilepis rikiki, the arthrodire groenlandaspidid Turrisaspis strudensis and the phyllolepidid Phyllolepis undulata. Based on morphological and morphometric evidence, the placoderm specimens from Strud are predominantly recognised as immature specimens and this locality as representing a placoderm nursery. The Strud depositional environment corresponds to a channel in an alluvial plain, and the presence of a nursery in such environment could have provided nutrients and protection to the placoderm offspring. This represents one of the earliest pieces of evidence for this sort of habitat partitioning in vertebrate history, with adults living more distantly from the nursery and using the nursery only to spawn or give live birth.

    2015-07-01

    Full Text Available The Short-Term Ensemble Prediction System (STEPS is implemented in real-time at the Royal Meteorological Institute (RMI of Belgium. The main idea behind STEPS is to quantify the forecast uncertainty by adding stochastic perturbations to the deterministic Lagrangian extrapolation of radar images. The stochastic perturbations are designed to account for the unpredictable precipitation growth and decay processes and to reproduce the dynamic scaling of precipitation fields, i.e. the observation that large scale rainfall structures are more persistent and predictable than small scale convective cells. This paper presents the development, adaptation and verification of the system STEPS for Belgium (STEPS-BE. STEPS-BE provides in real-time 20 member ensemble precipitation nowcasts at 1 km and 5 min resolution up to 2 h lead time using a 4 C-band radar composite as input. In the context of the PLURISK project, STEPS forecasts were generated to be used as input in sewer system hydraulic models for nowcasting urban inundations in the cities of Ghent and Leuven. Comprehensive forecast verification was performed in order to detect systematic biases over the given urban areas and to analyze the reliability of probabilistic forecasts for a set of case studies in 2013 and 2014. The forecast biases over the cities of Leuven and Ghent were found to be small, which is encouraging for future integration of STEPS nowcasts into the hydraulic models. Probabilistic forecasts of exceeding 0.5 mm h-1 are reliable up to 60–90 min lead time, while the ones of exceeding 5.0 mm h-1 are only reliable up to 30 min. The STEPS ensembles are slightly under-dispersive and represent only 80–90 % of the forecast errors.

    Since 2002, Belgium has had a national law legalising euthanasia. The law prescribes several substantive due care requirements and two procedural due care requirements, i.e. consultation with an independent physician and reporting of euthanasia to a Federal Control Committee. A large discrepancy in reporting rates between the Dutch-speaking (Flanders) and the French-speaking (Wallonia) parts of Belgium has led to speculation about cultural differences affecting the practice of euthanasia in both regions. Using Belgian data from the European Values Study conducted in 2008 among a representative sample of the general public and data from a large-scale mail questionnaire survey on euthanasia of 480 physicians from Flanders and 305 from Wallonia (conducted in 2009), this study presents empirical evidence of differences between both regions in attitudes towards and practice of euthanasia. Acceptance of euthanasia by the general population was found to be slightly higher in Flanders than in Wallonia. Compared with their Flemish counterparts, Walloon physicians held more negative attitudes towards performing euthanasia and towards the reporting obligation, less often labelled hypothetical cases correctly as euthanasia, and less often defined a case of euthanasia having to be reported. A higher proportion of Flemish physicians had received a euthanasia request since the introduction of the law. In cases of a euthanasia request, Walloon physicians consulted less often with an independent physician. Requests were more often granted in Flanders than in Wallonia (51% vs 38%), and performed euthanasia cases were more often reported (73% vs 58%). The study points out some significant differences between Flanders and Wallonia in practice, knowledge and attitudes regarding euthanasia and its legal requirements which are likely to explain the discrepancy between Wallonia and Flanders in the number of euthanasia cases reported. Cultural factors seem to play an important role in the

    In the context of the European Union ban on battery cages by 2012, a survey was conducted among Flemish egg producers (60% response rate, 140 completed questionnaires) about the introduction and opinion of alternative housing systems. Belgium appears to be among the countries in the European Union that are slower to adopt alternative housing. Belgium's egg industry is thus likely to undergo drastic changes to comply with the 2012 deadline. As of 2010, the battery cage was the dominant housing system (56% housing units, 67% hens), followed by floor housing (33% housing units, 15% hens) and aviary (10% housing units, 15% hens), whereas colony cages and furnished cages were extremely rare. Future- and market-oriented production was the most important reason for choosing a certain type of alternative system, although the importance of hen performance and amount of labor seemed to increase. A quarter of the producers with battery cages had detailed plans to convert to an alternative system (most planned to install aviaries, followed by colony cages, furnished cages, and floor housing) by 2012. Many older farmers indicated that they would stop farming, whereas others found it more profitable to delay the conversion as long as possible. Apart from hen welfare, producers expressed a negative opinion (relative to battery cages) about noncage systems and, to a lesser extent, furnished cages. However, users of alternative systems reported being quite satisfied, except for the amount of labor and hen health. The housing system had several effects on user satisfaction: positive effect of flock size, negative effect of experience with battery cages, and negative effect of outdoor area on hen health. Although not all opinions were supported by evidence, such surveys provide feedback about the success of alternative systems in practice. This information is valuable to further improve these systems and to producers who have yet to convert. Moreover, producer attitude may determine

    Full Text Available Abstract Background Ticks are the most important pathogen vectors in Europe. They are known to be influenced by environmental factors, but these links are usually studied at specific temporal or spatial scales. Focusing on Ixodes ricinus in Belgium, we attempt to bridge the gap between current “single-sided” studies that focus on temporal or spatial variation only. Here, spatial and temporal patterns of ticks are modelled together. Methods A multi-level analysis of the Ixodes ricinus patterns in Belgium was performed. Joint effects of weather, habitat quality and hunting on field sampled tick abundance were examined at two levels, namely, sampling level, which is associated with temporal dynamics, and site level, which is related to spatial dynamics. Independent variables were collected from standard weather station records, game management data and remote sensing-based land cover data. Results At sampling level, only a marginally significant effect of daily relative humidity and temperature on the abundance of questing nymphs was identified. Average wind speed of seven days prior to the sampling day was found important to both questing nymphs and adults. At site level, a group of landscape-level forest fragmentation indices were highlighted for both questing nymph and adult abundance, including the nearest-neighbour distance, the shape and the aggregation level of forest patches. No cross-level effects or spatial autocorrelation were found. Conclusions Nymphal and adult ticks responded differently to environmental variables at different spatial and temporal scales. Our results can advise spatio-temporal extents of environment data collection for continuing empirical investigations and potential parameters for biological tick models.

  15. Regional modelling of the confined aquifers below the Boom clay in NE-Belgium

    International Nuclear Information System (INIS)

    Document available in extended abstract form only. In the framework of the Belgian research program on the long term management of high-level and/or long-lived radioactive waste coordinated by ONDRAF/NIRAS, the Boom Clay is considered as a reference host rock for the geological disposal of high-level radioactive waste in NE-Belgium (Campine area). The hydrogeological program at SCK.CEN supports the long-term performance assessments of the geological disposal of radioactive waste by performing a phenomenological research of the aquifer systems surrounding the studied disposal system. One of the important components of this programme is the regional hydrogeological modelling. The regional hydrogeology is studied using two main models - the steady state Neogene aquifer model (NAM) and the transient deep aquifer pumping model (DAP), developed to characterize and quantify the regional groundwater flow in, respectively, the aquifers lying above the Boom Clay in the Nete catchment area (NAM), and the aquifers lying below the Boom Clay in the Campine area (DAP). This paper describes the most recent update of the DAP model. The DAP model represents the confined part of the groundwater system located stratigraphically below the Boom Clay. This includes the parts of the Oligocene aquifer, the Bartoon aquitard system and the Ledo-Paniselian-Brusselian aquifer buried under the Boom Clay. Due to the considerable pumping from these aquifers in combination with a limited recharge, a gradual decrease in groundwater levels has been observed in more than 30-year piezometric records. In the DAP model, the shallow aquifer system overlying the Boom Clay is replaced by fixed head boundaries: this aquifer system is dominated by close-to-surface hydrological processes and the heads fluctuate seasonally without any apparent long-term trend. In the horizontal direction, the model extends to the south as far as the outcrops of the major aquitards: the Maldegem Formation confining the Ledo

    Full Text Available Shiga-like toxin Escherichia coli (STEC implicated in aqueous diarrhoea, haemorrhagic colitis and haemolytic uraemic syndrome, has become a serious health problem in various countries. In Belgium, all cases are sporadic and no outbreak has been detected so far. Cattle are thought to be a reservoir for E. coli O157:H7, and many foodborne diseases have been associated with the consumption of minced beef, beefburgers and raw milk. Recently, foodborne outbreaks were concerned with different unusual foods such as acidic products. Although some data suggest that STEC are not prevalent within dairy products, the aim of this work was to assess the prevalence of E. coli O157 and non-O157 STEC in raw milk cheeses produced in the southern part of Belgium (Wallonia. For this purpose, 153 frozen samples of soft and semi-soft cheeses made with raw cow, ewe and goat milk were analysed for the presence of E. coli O157 and STEC. By using a dynabeads immunomagnetic separation technique (Dynabeads anti-E. coli O157, Dynal followed by streaking onto sorbitol MacConckey agar, no sample was found contaminated by E. coli O157 serotype. By using polymerase chain reaction achieved from a loopful of confluent bacterial material growing onto MacConckey agar, the use of consensus primers detected stx genes in 11.1/ of the samples but Shiga-like toxin producing strains could be isolated only in five of them (3.3/. The isolation rate seems to be optimum for samples with a thermotolerant coliform count arround or below 102 cfu per g. The five Shiga-like toxin isolates were identified as belonging to the species Hafnia alvei or Enterobacter amnigenius without any accessory virulence factors needed to cause illness. Nevertheless, because of the ability of STEC to survive adverse conditions and the possibility for commensal non-pathogenic enteric bacteria to become pathogenic, raw milk cheeses are to be considered at risk for foodborne STEC contamination.

  17. The hourly life cycle carbon footprint of electricity generation in Belgium, bringing a temporal resolution in life cycle assessment

    International Nuclear Information System (INIS)

    Highlights: • This paper brings a temporal resolution in LCA of electricity generation. • Dynamic life cycle assessment of electricity production in Belgium for 2011. • The overall average GWP per kW h is 0.184 kg CO2eq/kW h. • The carbon footprint of Belgian electricity ranges from 0.102 to 0.262 kg CO2eq/kW h. - Abstract: In the booming research on the environmental footprint of, for example, electrical vehicles, heat pumps and other (smart) electricity consuming appliances, there is a clear need to know the hourly CO2 content of one kW h of electricity. Since the CO2 footprint of electricity can vary every hour; the footprint of for example an electric vehicle is influenced by the time when the vehicle is charged. With the availability of the hourly CO2 content of one kW h, a decision support tool is provided to fully exploit the advantages of a future smart grid. In this paper, the GWP (Global Warming Potential) per kW h for each hour of the year is calculated for Belgium using a Life Cycle Assessment (LCA) approach. This enables evaluating the influence of the electricity demand on the greenhouse gas emissions. Because of the LCA approach, the CO2 equivalent content does not only reflect activities related to the production of the electricity within a power plant, but includes carbon emissions related to the building of the infrastructure and the fuel supply chain. The considered feedstocks are nuclear combustible, oil, coal, natural gas, biowaste, blast furnace gas, and wood. Furthermore, renewable electricity production technologies like photovoltaic cells, hydro installations and wind turbines are covered by the research. The production of the wind turbines and solar panels is more carbon intensive (expressed per generated kW h of electricity) than the production of other conventional power plants, due to the lower electricity output. The overall average GWP per kW h is 0.184 kg CO2eq/kW h. Throughout the 2011 this value ranges from a minimum of 0

    Flood risk is in Belgium, as well as in other European countries, of considerable importance because of the dense population and high industrialisation along the river banks. During the last decades it has become evident that global climate change has the potential to produce changes in the temporal and spatial distribution of precipitation and potential evapotranspiration and as a consequence will bring along changes in hydrological extremes (floods and low flows). In addition, land use change can significantly affect the catchment hydrology by altering several hydrological processes such as infiltration, evapotranspiration and surface runoff. Examining the sensitivity of hydrologic responses to these human-induced climate and land use changes is essential in order to formulate solid water management policies that effectively deal with the changing conditions. Hydrological models provide a framework for analysing the complex impacts on catchment hydrology. The overall objective of this study is to evaluate the relative impact of urban expansion and climate change on the catchment hydrology. The Molenbeek catchment (48 km²) in central Belgium is taken as an example application. The streamflow in the selected catchment was simulated by coupling a simplified runoff model (SRM) to a complex hydrodynamic model, implemented in the InfoWorks RS modelling system. The model was calibrated and validated using observed land cover maps of 1988 and 2000 and a 15-min series of water depths, measured at the catchment outlet. Preliminary results show that the calibrated model is able to predict both the peak flows and the total flow volumes relatively well for a selection of summer and winter rainfall events. Finally, a sensitivity analysis was carried out to assess possible future high flows in the catchment under different scenarios of urban expansion and climate change. In a first step, the impacts of climate change and urban expansion were evaluated separately. Next, the

  19. Accessibility to primary health care in Belgium: an evaluation of policies awarding financial assistance in shortage areas

    Science.gov (United States)

    2013-01-01

    Background In many countries, financial assistance is awarded to physicians who settle in an area that is designated as a shortage area to prevent unequal accessibility to primary health care. Today, however, policy makers use fairly simple methods to define health care accessibility, with physician-to-population ratios (PPRs) within predefined administrative boundaries being overwhelmingly favoured. Our purpose is to verify whether these simple methods are accurate enough for adequately designating medical shortage areas and explore how these perform relative to more advanced GIS-based methods. Methods Using a geographical information system (GIS), we conduct a nation-wide study of accessibility to primary care physicians in Belgium using four different methods: PPR, distance to closest physician, cumulative opportunity, and floating catchment area (FCA) methods. Results The official method used by policy makers in Belgium (calculating PPR per physician zone) offers only a crude representation of health care accessibility, especially because large contiguous areas (physician zones) are considered. We found substantial differences in the number and spatial distribution of medical shortage areas when applying different methods. Conclusions The assessment of spatial health care accessibility and concomitant policy initiatives are affected by and dependent on the methodology used. The major disadvantage of PPR methods is its aggregated approach, masking subtle local variations. Some simple GIS methods overcome this issue, but have limitations in terms of conceptualisation of physician interaction and distance decay. Conceptually, the enhanced 2-step floating catchment area (E2SFCA) method, an advanced FCA method, was found to be most appropriate for supporting areal health care policies, since this method is able to calculate accessibility at a small scale (e.g. census tracts), takes interaction between physicians into account, and considers distance decay. While at

    Global Circulation Models (GCMs) are sophisticated tools to study the future evolution of the climate. Yet, the coarse scale of GCMs of hundreds of kilometers raises questions about the suitability for agricultural impact assessments. These assessments are often made at field level and require consideration of interactions at sub-GCM grid scale (e.g., elevation-dependent climatic changes). Regional climate models (RCMs) were developed to provide climate projections at a spatial scale of 25-50 km for limited regions, e.g. Europe (Giorgi and Mearns, 1991). Climate projections from GCMs or RCMs are available as multi-model ensembles. These ensembles are based on large data sets of simulations produced by modelling groups worldwide, who performed a set of coordinated climate experiments in which climate models were run for a common set of experiments and various emissions scenarios (Knutti et al., 2010). The use of multi-model ensembles in climate change studies is an important step in quantifying uncertainty in impact predictions, which will underpin more informed decisions for adaptation and mitigation to changing climate (Semenov and Stratonovitch, 2010). The objective of our study was to evaluate the effect of the spatial scale of climate projections on climate change impacts for cereals in Belgium. Climate scenarios were based on two multi-model ensembles, one comprising 15 GCMs of the Coupled Model Intercomparison Project phase 3 (CMIP3; Meehl et al., 2007) with spatial resolution of 200-300 km, the other comprising 9 RCMs of the EU-ENSEMBLES project (van der Linden and Mitchell, 2009) with spatial resolution of 25 km. To be useful for agricultural impact assessments, the projections of GCMs and RCMs were downscaled to the field level. Long series (240 cropping seasons) of local-scale climate scenarios were generated by the LARS-WG weather generator (Semenov et al., 2010) via statistical inference. Crop growth and development were simulated with the Aqua

    Fear of childbirth has gained importance in the context of increasing medicalization of childbirth. Belgian and Dutch societies are very similar but differ with regard to the organization of maternity care. The Dutch have a high percentage of home births and low medical intervention rates. In contrast, home births in Belgium are rarer, and the medical model is more widely used. By comparing the Belgian and Dutch maternity care models, the association between fear of childbirth and medicalizat...

    We describe the application of statistical emulation to the outcomes of an agent-based model. The agent-based model simulates the mechanisms that might have linked the reversal of gender inequality in higher education with observed changes in educational assortative mating in Belgium. Using the statistical emulator as a computationally fast approximation to the expensive agent-based model, it is feasible to use a genetic algorithm in nding the parameter values for which the correspondin...

  10. Repair criteria and methods of repair for concrete structures of nuclear power plants - Particular application on natural draught cooling towers in belgium

    International Nuclear Information System (INIS)

    A previous paper was presented at the OCDE Workshop held 22-23 March 2000 in Brussels explaining different aspects of the techniques used for 'Instrumentation and monitoring of natural draught cooling towers in Belgium'. These monitoring and preventive techniques are now applied in Belgium since already more then 10 years by Tractebel on the towers of the nuclear plants. These huge constructions have to sustain considerable physical, chemical and biological loads. As one can figure out, and as years go by, these inspections showed deterioration of which type, progress, quantity eventually led to the need of repairing these structures. The present paper goes over 4 main different sorts of defects (beam supports breaking, fast carbonation rate, concrete porosity, and a series of local deteriorations like insufficient concrete cover, cracking, gravel pockets, corroded reinforcement) encountered on 3 cooling towers situated in Belgium, and affecting the shell as well as the inner structures. The diagnosis, the choice of the appropriate repair techniques and products which will avoid having to face much higher costs in the future are explained. It also gives an illustration of the works carried on site and points out the uncommon and complex aspects the treatment of such a construction implies (planning, both horizontal and vertical curved shape, works at great height,...).

    In July 2013, a Belgian couple were admitted to hospital because of pneumonia. Medical history revealed contact with birds. Eleven days earlier, they had purchased a lovebird in a pet shop in The Netherlands. The bird became ill, with respiratory symptoms. The couple's daughter who accompanied them to the pet shop, reported similar symptoms, but was travelling abroad. On the suspicion of psittacosis, pharyngeal swabs from the couple were taken and sent to the Belgian reference laboratory for psittacosis. Culture and nested polymerase chain reaction (PCR) tests were positive for the presence of Chlamydia psittaci, and ompA genotyping indicated genotype A in both patients. The patients were treated with doxycycline and the daughter started quinolone therapy; all three recovered promptly. Psittacosis is a notifiable disease in Belgium and therefore local healthcare authorities were informed. They contacted their Dutch colleagues, who visited the pet shop. Seven pooled faecal samples were taken and analysed using PCR by the Dutch national reference laboratory for notifiable animal diseases for the presence of Chlamydia psittaci. Four (57%) samples tested positive, genotyping revealed genotype A. Enquiring about exposure to pet birds is essential when patients present with pneumonia. Reporting to health authorities, even across borders, is warranted to prevent further spread. PMID:26669637

    Isotopic fingerprinting is an advanced technique allowing the classification of the nitrate source pollution of groundwater, but needs further development and validation. In this study, we performed measurements of natural stable isotopic composition of nitrate ((15)N and (18)O) in the groundwater body of the Brussels sands (Belgium) and studied the spatial and temporal dynamics of the isotope signature of this aquifer. Potential nitrogen sources sampled in the region had isotopic signatures that fell within the corresponding typical ranges found in the literature. For a few monitoring stations, the isotopic data strongly suggest that the sources of nitrate are from mineral fertiliser origin, as used in agriculture and golf courses. Other stations suggest that manure leaching from unprotected stockpiles in farms, domestic gardening practices, septic tanks and probably cemeteries contribute to the nitrate pollution of this groundwater body. For most monitoring stations, nitrate originates from a mixing of several nitrogen sources. The isotopic signature of the groundwater body was poorly structured in space, but exhibited a clear temporal structure. This temporal structure could be explained by groundwater recharge dynamics and cycling process of nitrogen in the soil-nitrogen pool.

    In 2006, Belgium was the first country in the European Union to recommend rotavirus vaccination in the routine infant vaccination schedule and rapidly achieved high vaccine uptake (86-89% in 2007). We used regional and national data sources up to 7 years post-vaccination to study the impact of vaccination on laboratory-confirmed rotavirus cases and rotavirus-related hospitalisations and deaths. We showed that (i) from 2007 until 2013, vaccination coverage remained at 79-88% for a complete course, (ii) in children 0-2 years, rotavirus cases decreased by 79% (95% confidence intervals (CI): 68--89%) in 2008-2014 compared to the pre-vaccination period (1999--2006) and by 50% (95% CI: 14-82%) in the age group ≥ 10 years, (iii) hospitalisations for rotavirus gastroenteritis decreased by 87% (95% CI: 84-90%) in 2008--2012 compared to the pre-vaccination period (2002--2006), (iv) median age of rotavirus cases increased from 12 months to 17 months and (v) the rotavirus seasonal peak was reduced and delayed in all post-vaccination years. The substantial decline in rotavirus gastroenteritis requiring hospitalisations and in rotavirus activity following introduction of rotavirus vaccination is sustained over time and more pronounced in the target age group, but with evidence of herd immunity.

    Full Text Available Dust deposition in southern Belgium is estimated from the geochemical signature of an ombrotrophic peatland. The Rare Earth Elements (REE and lithogenic elements concentrations, as well as Nd isotopes, were determined by HR-ICP-MS and MC-ICP-MS respectively, in along a ~6 m peat section covering 5300 yr, from 30 BC to 5300 BC dated by the 14C method. Changes in REE concentration in the peat correlate with those of Ti, Al, Sc and Zr that are lithogenic conservative elements, suggesting that REE are immobile in the studied peat bogs and can be used as tracers of dust deposition. Peat humification and testate amoebae were used to evaluate hydroclimatic conditions. The range of dust deposition varied from 0.03 to 4.0 g m−2 yr−1. The highest dust fluxes were observed from 800 to 600 BC and from 3200 to 2800 BC and correspond to cold periods. The εNd values show a large variability of −5 to −13, identifying three major sources of dusts: local soils, distal volcanic and desert particles.

    Paediatric injury surveillance and prevention are definite priorities for the European, Belgian, and Flemish authorities. Current available data for Flanders (Belgium) are fragmentary and out-of-date. The PENTA registry (PaEdiatric Network around TraumA) was therefore set up to obtain recent population-based data on trauma and trauma care in children and youngsters in Flanders. Data were collected prospectively in a representative sample (n = 18) of Flemish emergency departments (ED). All children (age 0-17 years) who presented at the ED in 2005 or died prehospital due to trauma were included. The registry was split into two levels. The basic A registry ('all' trauma) consisted of 30 variables, and the more exhaustive B registry ('severe trauma', defined as length of hospitalisation >48 hours, including all nonsurvivors) collected data on 291 variables. The incidence for paediatric trauma presenting at Flemish ED was approximately 119/1000/year. Further data were collected in a random sample of 7,879 cases (21.9% of 35,900 eligible patients). Of all cases, 0.8% were considered 'severe' and included in the B registry. In conclusion, the 'burden' of injury in Flanders is still enormous. PENTA provides the first population-based data about the circumstances and the extent of injury in children and youngsters for the Flemish region. In this article we present in detail the surplus value of the methods used, the difficulties encountered, and the most relevant epidemiological findings from the registry. PMID:18202851

    In the light of the European Directive on Energy Performance of Building, Vito participated in the conception of the official method for the evaluation of energy performance of existing buildings by order of the Belgian authorities. The present residential sector in Belgium has some very specific difficulties. Because of the high average age of the buildings and the typical personal construction culture, there is an enormous diversity of the existing houses. A labelling procedure should therefore take into account all possible aspects and construction data in order to allow a useful comparison. 41 existing houses have been evaluated with this new procedure. To ensure a thorough test, the diversity of the participating houses and installations has been chosen as large as possible. As a surplus value for the occupants of the house, the evaluation resulted in energy-saving recommendations for the building envelope, the heating installation and preparation of domestic hot water. The results are first of all a view on the applicability of this new procedure. Despite of the difficulties of comparison at first sight, the actual results give clear indications about the performance of the house in terms of energy consumption and energy savings potential. In order to further evaluate the procedure,, the actual implementation of the recommendations has been followed up. The procedure has been evaluated by means of questionnaires and qualitative sociological interviews. The results show important advantages and problems for future public acceptance of energy savings, once the European directives will be fully implemented.

    Effects of vegetation on pollutant dispersion receive increased attention in attempts to reduce air pollutant concentration levels in the urban environment. In this study, we examine the influence of vegetation on the concentrations of traffic pollutants in urban street canyons using numerical simulations with the CFD code OpenFOAM. This CFD approach is validated against literature wind tunnel data of traffic pollutant dispersion in street canyons. The impact of trees is simulated for a variety of vegetation types and the full range of approaching wind directions at 15° interval. All these results are combined using meteo statistics, including effects of seasonal leaf loss, to determine the annual average effect of trees in street canyons. This analysis is performed for two pollutants, elemental carbon (EC) and PM10, using background concentrations and emission strengths for the city of Antwerp, Belgium. The results show that due to the presence of trees the annual average pollutant concentrations increase with about 8% (range of 1% to 13%) for EC and with about 1.4% (range of 0.2 to 2.6%) for PM10. The study indicates that this annual effect is considerably smaller than earlier estimates which are generally based on a specific set of governing conditions (1 wind direction, full leafed trees and peak hour traffic emissions).

    Full Text Available Background. Monitoring the epidemiology of cardiovascular risk factors (CRFs and their determinants is important to develop appropriate recommendations to prevent cardiovascular diseases in specific risk groups. The NESCaV study was designed to collect standardized data to estimate the prevalence of CRFs in relation to socioeconomic parameters among the general adult population in the province of Liège, Wallonia, Belgium. Methods. A representative stratified random sample of 1017 subjects, aged 20–69 years, participated in the NESCaV study (2010–2012. A self-administered questionnaire, a clinical examination, and laboratory tests were performed on participants. CRFs included hypertension, dyslipidemia, global obesity, abdominal obesity, diabetes, current smoking, and physical inactivity. Covariates were education and subjective and objective socioeconomic levels. Data were analyzed by weighted logistic regression. Results. The prevalence of hypertension, abdominal obesity, global obesity, current smoking, and physical inactivity was higher in subjects with low education and who considered themselves “financially in need.” Living below poverty threshold also increased the risk of global and abdominal obesity, current smoking, and physical inactivity. Conclusion. The study shows that socioeconomic factors impact the prevalence of CRFs in the adult population of Wallonia. Current public health policies should be adjusted to reduce health inequalities in specific risk groups.

  20. Four Perspectives of Sustainability Applied to the Local Food Strategy of Ghent (Belgium: Need for a Cycle of Democratic Participation?

    Full Text Available As part of cities’ increasing commitment to sustainable development, local food systems are becoming a policy priority. In this article we focus on the case of a local food system in Ghent, Belgium. We adopt the notion of Hajer et al. (2015 that top-down steering of environmental issues (so-called “cockpit-ism” is insufficient, incomplete and in need of revision. Using their four perspectives on sustainable development (Hajer et al., 2015, we explore, analyze and valorize the potential of the actors, motives and logics for change within the agriculture and food system in the Ghent region. Applying these four perspectives, we have mapped the current positive developments as well as identified the weaknesses, pitfalls and opportunities of a local food strategy. The discussion section contains two important strategies for good governance of sustainable urban development: first, a governance approach to stimulate participation and representation in a complex, unequal and rapidly changing context; and second, a reflection on how local food strategies can drive global sustainability. In conclusion, we argue for the integration of a global sustainability approach within sustainable urban development.

  1. Stakeholder Involvement in Radioactive Waste Management in Belgium: the Past, the Present and Challenges for the Future

    At present stakeholder involvement in RWM in Belgium focuses solely on siting a LILW-repository, engaging primarily local citizen-stakeholders. If accepting the value of participation in this programme, which NIRAS/ONDRAF explicitly states, the biggest future challenge for the agency will be to match the efforts in its LILWprogramme with similar efforts for the whole of its management operations, both short-term and long-term; and both site specific as well as on a general policy level. The local partnerships (in particular STORA and MONA) today have become NIRAS/ONDRAF's most important stakeholders. Their insisting on opening up a HLW-debate (but without the intention of turning it into a site selection process) might therefore be just the leverage needed to move from a declaration of intent to the setting up of an active participatory programme. Although some might regret it, the introduction of the partnership approach has opened up a Pandora's box, creating self-awareness and self-identification among a particular group of stakeholders who clearly are not prepared to be backing out of their new role in the immediate future.

    In an increasingly complex waste market, market-based policy instruments, such as disposal taxes, can give incentives for sustainable progress while leaving flexibility for innovation. However, implementation of disposal taxes is often criticised by domestic waste handlers that fear to be outcompeted by competitors in other countries. The article discusses three innovative market-based instruments that limit the impact on international competitiveness: Tradable recycling credits, refunded disposal taxes and differentiated disposal taxes. All three instruments have already been implemented for distinct environmental policies in Europe. In order to illustrate how these instruments can be used for waste policy, the literature review is complemented with a case study on shredder residues from metal-containing waste streams in Belgium. The analysis shows that a conventional disposal tax remains the most efficient, simple and transparent instrument. However, if international competition is a significant issue or if political support is weak, refunded and differentiated disposal taxes can have an added value as second-best instruments. Tradable recycling credits are not an appropriate instrument for use in small waste markets with market power. In addition, refunded taxes create similar incentives, but induce lower transactions costs. PMID:26395844

  3. Status of the fast breeder reactor development in the Federal Republic of Germany, Belgium and the Netherlands

    International Nuclear Information System (INIS)

    In 1967 and 1968 the Federal Republic of Germany, the Kingdom of Belgium and the Kingdom of the Netherlands (''DeBeNe'') agreed to develop, in a joint program, breeder reactors to the point of commercial maturity. The following research organizations take part in this effort: Kernforschungszentrum Karlsruhe (KfK); INTERATOM, Bergisch Gladbach; ALKEM, Wolfgang near Hanau; SCK/CEN, Mol; Belgonucleaire, Brussels; ECN, Petten; TNO, Apeldoorn; NERATOOM, The Hague. The three German institutions mentioned above have been interrelated since 1977 by the Entwicklungsgemeinschaft (EG) Schneller Brueter. Between KfK, INTERATOM, and the French Commissariat a l'Energie Atomique contracts were concluded in 1977 about close cooperation in the Fast Breeder field, with association of the Belgian and Dutch partners. The results of research and development activities carried out by the DeBeNe partners in 1981 have been compiled in this report. The report begins with a short survey of the fast reactor plants, followed by an R and D summary. The bulk of the report gives more detailed information about those plants and about results reported by the Working Groups of the R and D Program Working Committee of the Fast Breeder Project. In an additional chapter a survey is given of international cooperation. (author)

    Recurrent Sexually Transmitted Infections (STIs) are an indication of unsafe sexual practices and may be associated with HCV-infection among HIV-positive men who have sex with men. In a retrospective study we analysed the laboratory data of 99 HIV-positive MSM who acquired HCV during the observation period (cases) and 176 HIV-positive MSM who remained HCV negative during the observation period (controls), all followed at the HIV/STI-clinic in Antwerp, Belgium. All laboratory confirmed STI-episodes were recorded since the date of first consultation at our clinic, until the date of HCV-diagnosis of the cases. The HCV incidence varied between 0.24 (2001) and 1.36 (2011) new cases per hundred person-years, with a peak of 2.93 new cases per hundred person-years in 2009. The number of STI-episodes per person-year follow-up was significantly higher for the cases as compared to the controls for syphilis, non-LGV and LGV Chlamydia infections (p HCV conversion, all laboratory confirmed STIs remained more frequent among cases, but only the difference in syphilis incidence was statistically significant (p HCV and should lead to intensified screening for HCV and counselling of the patient.

  5. Freedom-costs of canonical individualism: enforced euthanasia tolerance in Belgium and the problem of European liberalism.

    2006-08-01

    Belgium's policy of not permitting Catholic hospitals to refuse euthanasia services rests on ethical presuppositions concerning the secular justification of political power which reveal the paradoxical character of European liberalism: In endorsing freedom as a value (rather than as a side constraint), liberalism prioritizes first-order intentions, thus discouraging lasting moral commitments and the authority of moral communities in supporting such commitments. The state itself is thus transformed into a moral community of its own. Alternative policies (such as an explicit moral diversification of public healthcare or the greater tolerance for Christian institutions in the Netherlands) are shown to be incompatible with Europe's liberal concern with securing social and material freedom resources, as well as the concern with equality of opportunity, as embodied in the European Union's anti-discrimination labor law. The essay's argument for the preferability of a libertarian solution closes with the challenge that only if the provision of public healthcare can be shown to be rationally indispensable for a morally justified polity, could the exposed incoherence of modern European liberalism be generously discounted.

  6. Comprehensive bee pathogen screening in Belgium reveals Crithidia mellificae as a new contributory factor to winter mortality.

    Directory of Open Access Journals (Sweden)

    Jorgen Ravoet

    Full Text Available Since the last decade, unusually high honey bee colony losses have been reported mainly in North-America and Europe. Here, we report on a comprehensive bee pathogen screening in Belgium covering 363 bee colonies that were screened for 18 known disease-causing pathogens and correlate their incidence in summer with subsequent winter mortality. Our analyses demonstrate that, in addition to Varroa destructor, the presence of the trypanosomatid parasite Crithidia mellificae and the microsporidian parasite Nosema ceranae in summer are also predictive markers of winter mortality, with a negative synergy being observed between the two in terms of their effects on colony mortality. Furthermore, we document the first occurrence of a parasitizing phorid fly in Europe, identify a new fourth strain of Lake Sinai Virus (LSV, and confirm the presence of other little reported pathogens such as Apicystis bombi, Aphid Lethal Paralysis Virus (ALPV, Spiroplasma apis, Spiroplasma melliferum and Varroa destructor Macula-like Virus (VdMLV. Finally, we provide evidence that ALPV and VdMLV replicate in honey bees and show that viruses of the LSV complex and Black Queen Cell Virus tend to non-randomly co-occur together. We also noticed a significant correlation between the number of pathogen species and colony losses. Overall, our results contribute significantly to our understanding of honey bee diseases and the likely causes of their current decline in Europe.

    Full Text Available The Meuse is an important rain-fed river in North-Western Europe. Nine million people live in its catchment, split over five countries. Projected changes in precipitation and temperature characteristics due to climate change would have a significant impact on the Meuse River and its tributaries. In this study, we focused on the impacts of climate change on the hydrology of two sub-catchments of the Meuse in Belgium, the Lesse and the Vesdre, placing the emphasis on the water-soil-plant continuum in order to highlight the effects of climate change on plant growth, and water uptake on the hydrology of two sub-catchments. These effects were studied using two climate scenarios and a physically based distributed model, which reflects the water-soil-plant continuum. Our results show that the vegetation will evapotranspirate between 10 and 17 % less at the end of the century because of water scarcity in summer, even if the root development is better under climate change conditions. In the low scenario, the mean minimal 7 days discharge value could decrease between 19 and 24 % for a two year return period, and between 20 and 35 % for a fifty year return period. It will lead to rare but severe drought in rivers, with potentially huge consequences on water quality.

    Precipitation is the main driving force for hydrological processes. There are however other physical variables, like soil moisture, that play an essential role in the hydrological cycle. In the present study, we focus on the use of a surface soil moisture (SSM) product in hydrological modelling. This product is generated using MetOp scatterometer (ASCAT) data at 25 km of horizontal resolution in the framework of the H-SAF project (EUMETSAT Satellite Application Facility on Support to Operational Hydrology and Water Management). The Royal Meteorological Institute of Belgium (RMI) is an active partner of H-SAF, involved in the validation of precipitation, soil moisture and snow products. In this work, we include in our hydrological simulations a soil moisture product through a data assimilation procedure. Our approach is based on the Ensemble Kalman Filter technique where observation and model uncertainties are taken into account. We first develop an assimilation scheme for surface soil moisture into the hydrological model of the RMI. In our implementation, bounded variables like SSM are handled with the aid of specially designed probability distributions so that the bounds are never exceeded. Subsequently, the impact of SSM assimilation on the simulated streamflow is assessed by using different sources of precipitation forcing. The ultimate goal is to provide new tools of hydrological validation and to investigate the possibilities of enhancing the quality of the simulated streamflow.

  10. Collective Memories of WWII Collaboration in Belgium and Attitudes About Amnesty in the Two Main Linguistic Communities

    2014-03-01

    Full Text Available Collaboration with the Nazi occupier during WWII has always been a topic of dissent between French-speakers (FS and Dutch-speakers (DS in Belgium. According to a popular myth coined after the war and often narrated in the media and literature, collaboration was widespread in Flanders, whereas Walloons bravely resisted, although historical reality is much more nuanced. These representations regularly resurface in political debates surrounding the Belgian linguistic conflict. Demands for amnesty addressed by nationalist Flemish parties are a case in point. A questionnaire survey (N = 521; 315 FS and 206 DS showed that collaboration was represented negatively and was morally condemned in both groups. However, DS expressed more Support for Amnesty (SA than FS. This effect of Linguistic Group (LG on SA was mediated by judgment of morality of collaboration, and this mediation was moderated by identification with the LG. Interestingly, SA was predicted by judgments of morality of DS, but not of FS, collaborators, in both groups, as if francophone collaboration was deemed irrelevant. Results suggest that differences between DS and FS in political position taking regarding the granting of amnesty are partly due to differences in representations of collaboration, and to different perspectives towards the same historical representation. The myth is both shared and disputed.

    We report here baseline data from the first year of compulsory surveillance of Clostridium difficile infections (CDI) in hospitals in Belgium. Between 1 July 2007 and 30 June 2008, 2,704 CDI were reported: 12% were recurrent and 66% were hospital-associated (half of which occurred 15 days or more after admission). CDI was considered the cause of death (direct or indirect) for 10% of the episodes. The median incidence of CDI was 1.5 per 1,000 admissions and 1.9 per 10,000 hospital-days for all cases, and 0.9 per 1,000 admissions, and 1.1 per 10,000 hospital-days for hospital-associated cases. Further investigation of risk stratification by average length of stay in the reporting hospitals is warranted as a way to improve the comparability of indicators across hospitals and surveillance systems. In spite of methodological issues, the surveillance of CDI in Belgian hospitals has been able to produce robust baseline data that should allow monitoring of trends at hospital and national level, and provide a basis for international comparisons. Remaining challenges are to define and monitor targets for the control of CDI, and to improve the individual feed-back of data at hospital level. PMID:19371509

  13. Realizing good care within a context of cross-cultural diversity: an ethical guideline for healthcare organizations in Flanders, Belgium.

    2013-09-01

    In our globalizing world, health care professionals and organizations increasingly experience cross-cultural challenges in care relationships, which give rise to ethical questions regarding "the right thing to do" in such situations. For the time being, the international literature lacks examples of elaborated ethical guidelines for cross-cultural healthcare on the organizational level. As such, the ethical responsibility of healthcare organizations in realizing cross-cultural care remains underexposed. This paper aims to fill this gap by offering a case-study that illustrates the bioethical practice on a large-scale organizational level by presenting the ethical guideline developed in the period 2007-2011 by the Ethics Committee of Zorgnet Vlaanderen, a Christian-inspired umbrella organization for over 500 social profit healthcare organizations in Flanders, Belgium. The guideline offers an ethical framework within which fundamental ethical values are being analyzed within the context of cross-cultural care. The case study concludes with implications for healthcare practice on four different levels: (1) the level of the healthcare organization, (2) staff, (3) care receivers, and (4) the level of care supply. The study combines content-based ethics with process-based benchmarks.

    The interactions between land surface and climate are complex. Climate changes can affect ecosystem structure and functions, by altering photosynthesis and productivity or inducing thermal and hydric stresses on plant species. These changes then impact socio-economic systems, through e.g., lower farming or forestry incomes. Ultimately, it can lead to permanent changes in land use structure, especially when associated with other non-climatic factors, such as urbanization pressure. These interactions and changes have feedbacks on the climate systems, in terms of changing: (1) surface properties (albedo, roughness, evapotranspiration, etc.) and (2) greenhouse gas emissions (mainly CO2, CH4, N2O). In the framework of the MASC project (« Modelling and Assessing Surface Change impacts on Belgian and Western European climate »), we aim at improving regional climate model projections at the decennial scale over Belgium and Western Europe by combining high-resolution models of climate, land surface dynamics and socio-economic processes. The land surface dynamics (LSD) module is composed of a dynamic vegetation model (CARAIB) calculating the productivity and growth of natural and managed vegetation, and an agent-based model (CRAFTY), determining the shifts in land use and land cover. This up-scaled LSD module is made consistent with the surface scheme of the regional climate model (RCM: ALARO) to allow simulations of the RCM with a fully dynamic land surface for the recent past and the period 2000-2030. In this contribution, we analyze the results of the first simulations performed with the CARAIB dynamic vegetation model over Belgium at a resolution of 1km. This analysis is performed at the species level, using a set of 17 species for natural vegetation (trees and grasses) and 10 crops, especially designed to represent the Belgian vegetation. The CARAIB model is forced with surface atmospheric variables derived from the monthly global CRU climatology or ALARO outputs

    2005-06-01

    In Belgium, the regions are responsible for any matters related to renewable energy sources. In the Flemish region, a system of green certificates and a system of free distribution of green electricity were introduced with a view to promote the local production of energy from renewable sources. Under the green certificates system, the electricity suppliers could only comply with their obligations by submitting a sufficient number of green certificates awarded for green electricity produced in the Flemish region or in the territorial sea (other certificates would not be accepted). Under the system of free distribution, no distribution costs were charged for using the Flemish distribution grid (to the benefit of the electricity supplier and consequently the end-user) to the extent that the electricity was produced by production installations connected to the Flemish distribution grid. Both systems were severely criticized by the Belgian State Council (the supreme administrative court) and the European Commission, and were found contrary to the rules of free movement of goods within the Belgian territory and within the EU. This criticism might introduce the end of the principles contained in the decision of the European Court of Justice in the Preussen-Elektra / Schleswag AG matter, where the European Court of Justice had allowed discrimination in favour of local producers of renewable energy for very specific reasons. Meanwhile, in the Flemish region, the system of free distribution has been abolished.The next question is whether the above criticism also leads to a situation where green certificates issued in one EU Member State must be accepted in all other EU Member States to comply with a local obligation to submit a specific number of green certificates.The consequences for EU Member States with only limited renewable energy sources (such as Belgium) may be far reaching.

  16. Use and experience of radiological evaluation tools for the early phase during nuclear emergency exercises in Belgium

    International Nuclear Information System (INIS)

    Full text: The Royal Decree on 'The Emergency Plan for Nuclear Risks an the Belgian Territory' describes the role and tasks of the different stakeholders involved in case of a nuclear crisis affecting Belgium. The crisis is managed from within the Governmental Crisis Coordination Centre in Brussels where various functional cells meet according to the notification and alarm levels. Decisions about countermeasures are taken at federal level by a Coordination Committee headed by the Minister of Interior. These may be preceded by rapid decision making initiated at provincial and local levels in case of an imminent radiological threat. An information cell stands for the release of official information and instructions to the media and the public and for the monitoring of public reactions. A crucial step for a sound intervention decision making is the radiological evaluation process. The evaluation cell is responsible to gather all relevant information, to analyse it and to give advice on the best intervention strategy to the coordination committee. The primary source of information originates from the nuclear operator which must legally transmit recurrent information about the actual and forecasted status and release of the plant, the actual meteorological situation, the expected off-site radiological consequences and, if possible, environmental measurements. The evaluation cell is assisted by the measurement cell which elaborates and executes a monitoring campaign based an advice of the evaluation cell. The national monitoring network called Telerad provides another input of information. In consultation with the authorities, a rather simple yet highly flexible radiological evaluation tool to be used by the two main nuclear power plants in Belgium (Doel and Tihange) during the early phase has been developed by SCK-CEN, i.e. Noodplan Kerncentrale Doel and Plan d'Urgence Zone de Production Nucleaire de Tihange.

    Full Text Available Abstract Background In order to select priority hotspots for environment and health research in Flanders (Belgium, an open procedure was organized. Environment and health hotspots are strong polluting point sources with possible health effects for residents living in the vicinity of the hot spot. The selection procedure was part of the work of the Flemish Centre of Expertise for Environment and Health, which investigates the relation between environmental pollution and human health. The project is funded and steered by the Flemish government. Methods The involvement of other actors than merely experts is inspired by the 'analytical-deliberative' approach of the National Research Council in the United States and the extended peer community approach. These approaches stress the importance of involving different expert- and social perspectives in order to increase the knowledge base on complex issues. In the procedure used in the project a combination of expert and stakeholder input was essential. The final decision was supported by a multi-criteria analysis of expert assessment and stakeholder advice. Results The endeavour was challenging from the start because of the complicated ambition of including a diversity of actors, potential hotspots, concerns and assessment criteria, but nevertheless the procedure proved its value in both structuring and informing the decision-making process. Moreover the process gained the support of most actors participating in the process, even though the final selection could not satisfy all preferences. Conclusions Opening the research agenda exemplifies the value of inter- and transdisciplinary cooperation as well as the need for a well-structured and negotiated procedure that combines relevant factors and actors with pragmatism. The value of such a process also needs to prove itself in practice after the procedure has been completed: the tension between an ambition of openness on the one hand and a more closed

    For several decades policy makers worldwide have experimented with testimonials as a strategy to promote road safety supportive views in a wide variety of target populations such as recidivists and students. In its basic format, a (relative of) a victim or an offender brings a personal testimonial of what it is to experience a traffic accident. The underlying idea is that such a testimonial will emotionally affect participants, thereby stimulating them to cognitively reflect upon their own behavior and responsibility as a road user. Unfortunately, empirical literature on the effectiveness of this strategy is rather scarce and inconsistent. This study investigated the effect of a large-scale program with victim testimonials for high schools in Belgium on five socio-cognitive and behavioral variables drawn from the Theory of Planned Behavior (i.e., attitude, subjective norm, perceived behavioral control, behavioral intention and behavior). Moreover, this study investigated program effects on participants' cognitive and emotional estate and whether this influences the program's impact on socio-cognitive and behavioral variables. Our test sample included 1362 students, who were assigned to a baseline - follow-up group and a post-test - follow-up group. We questioned both groups, a first time (just before or after session attendance) on paper, and a second time (two months after session attendance) online. Results indicate the program had, both immediate and two months after attendance, small to medium positive effects on most socio-cognitive and behavioral variables. However, effects depended on participants' demographic profile, their baseline values on the socio-cognitive and behavioral variables, and the degree to which they were cognitively/emotionally affected by the program. We discuss the practical implications of these findings and formulate recommendations for the development of future interventions based on victim testimonials. PMID:27240125

    Full Text Available For many centuries, coppice-with-standards management was applied in the mixed oak stands of Meerdaal forest (Belgium. Over the last century, these stands were gradually converted to high forest. On an area of 20 ha, the coppice-with-standards management is being restored, with specific adaptations for biodiversity (conservation of dead wood and veteran trees. A survey of saproxylic beetles was performed at 8 locations in the forest, including one site within the coppice-with-standards restoration. This survey not only allowed an evaluation of the saproxylic beetle richness of the forest complex, but also made exploratory observations on the effect of this type of management, as compared to non-intervention, on species richness and composition of saproxylic beetles. The results show that the overall species richness in the forest complex was quite high and comparable to forest reserves in Germany. Both coppice-with-standards and high forest options appear to be equally species-rich, but consist of different communities, both containing specific, rare and notable species, with more thermophilous and light-demanding species in the coppice-with-standards plot. Based on these observations we suggest that a diversified management approach may be the most suitable to conserve and enhance diverse saproxylic beetle communities in formerly intensively managed semi-natural woodlands. This could include areas of active conservation management aimed at producing open-canopy stands with considerable amounts of sun-exposed deadwood, combined with areas of non-intervention in a matrix of multifunctional forests, where conservation of dead wood and veteran trees is fully incorporated in the management.

    Accurate precipitation maps are essential for ecological, environmental, element cycle and hydrological models that have a spatial output component. It is well known that topography has a major influence on the spatial distribution of precipitation and that increasing topographical complexity is associated with increased spatial heterogeneity in precipitation. This means that when mapping precipitation using classical interpolation techniques (e.g. regression, kriging, spline, inverse distance weighting, etc.), a climate measuring network with higher spatial density is needed in mountainous areas in order to obtain the same level of accuracy as compared to flatter regions. In this study, we present a mean total annual precipitation mapping technique that combines topographical information (i.e. elevation and slope orientation) with average total annual rain gauge data in order to overcome this problem. A unique feature of this paper is the identification of the scale at which topography influences the precipitation pattern as well as the direction of the dominant weather circulation. This method was applied for Belgium and surroundings and shows that the identification of the appropriate scale at which topographical obstacles impact precipitation is crucial in order to obtain reliable mean total annual precipitation maps. The dominant weather circulation is determined at 260°. Hence, this approach allows accurate mapping of mean annual precipitation patterns in regions characterized by rather high topographical complexity using a climate data network with a relatively low density and/or when more advanced precipitation measurement techniques, such as radar, aren't available, for example in the case of historical data.

  1. R and D program concerning radioactive waste disposal in deep geologic formation (Study of an argilaceous formation in Belgium)

    International Nuclear Information System (INIS)

    In 1974 it was decided to start up research with a view to safe disposal of conditioned waste in geological formations in Belgium. A first R and D programme was set up for study of the Boom clay in the Mol region. Multiple research projects have been undertaken; both experimental research in the field and in the laboratory and theoretical studies. Different exploratory drillings for geohydrological and geotechnical research were performed at the potential site. Teledetection and seismic prospection campaigns have provided data on the dimensions of the argillaceous layer and on the absence of major faults. Clay samples collected during drilling campaigns have been submitted to a number of analyses in laboratory as well as analyses of possible interactions between the clay and the conditioned waste to be stored. Some of these laboratory analyses, in particular, those concerning heat transfer and corrosion have been completed by more representative experiments in a clay pit. Various mathematical models have been developed and adapted with a view to better understanding of physical and physico-chemical phenomena like heat transfer, migration and retardation of radionuclides. A feasibility study was performed. Concerning safety analyses, a probabilistic study was undertaken on the behaviour of the geological barrier. The fault tree analysis technique was applied and the study was carried out in close collaboration with the Joint Rsearch Centre in Ispra. The underground experimental room at about 220 m depth was not yet relised but the technico-economical dossier has made such progress that the excavation can start in the very beginning of the next five-year programme

  2. GIS-based assessment of the biomass potential from phytoremediation of contaminated agricultural land in the Campine region in Belgium

    International Nuclear Information System (INIS)

    Dedicated energy crop cultivation is expected to be the prevalent form of biomass production for reaching renewable energy targets set by the European Union. However, there are some concerns with regard to its sustainability. This study demonstrates how this problem can be evaded by applying phytoremediation, i.e. the use of plants to remove pollutants from moderately contaminated soils. By selecting the appropriate plants a considerable biomass flow is produced without taking in scarce agricultural land, while simultaneously remediating the soil to levels of contamination below threshold values. Since phytoremediation is only applicable within a limited range of soil pollutant concentrations, the outer values of this range have to be determined at first. Subsequently, a Geographic Information System (GIS) is needed to perform further analyses. The contamination in the region is predicted using GIS, after which the agricultural area is determined that can be committed to energy crop cultivation. This way, the biomass potential and the resulting bioenergy potential from phytoremediation can be assessed. In this paper the Campine region in Belgium, a region diffusely contaminated with heavy metals like cadmium (Cd), is examined. It is illustrated that more than 2000 ha of agricultural land hold Cd concentrations exceeding guide values set by the Flemish Government. However, a large majority of these soils can be remediated by phytoremediation within a reasonable time span of 42 years. Concurrently, a significant amount of biomass is supplied for renewable energy production. -- Highlights: → More than 2000 ha of agricultural land have elevated Cd concentrations. → 87% can be remediated within 42 years by phytoremediation. → Annual biomass flow of 19 067 Mg for 21 years.

  3. Prevalence and sources of Campylobacter spp. contamination in free-range broiler production in the southern part of Belgium

    Full Text Available A one year epidemiological study was carried out between February 2005 and February 2006 in the southern part of Belgium to assess the Campylobacter prevalence in free-range broiler production. Three successive broiler flocks from six Belgian farms were investigated for the presence of Campylobacter spp. during the rearing period. Each flock was visited four times, before and after the outdoor rearing period. During each visit, samples were taken in the broiler house (litter, cecal droppings, water-lines, feed, anteroom as well as from the outer rearing environment (open-air range. The Campylobacter detection in all samples was carried out according to the ISO 10272 standard. Identification was based on colonial morphology, microscopic examination, and biochemical tests. PCR multiplex was used for genetic confirmation. Campylobacter jejuni was the main species isolated from all contaminated samples. Overall, mixed infections C. jejuni / Campylobacter coli represented 40.6%, while C. jejuni and C. coli represented 46.9% and 12.5% of chicken samples respectively. A 100% flock contamination was observed in the 6 farms during the summer-autumn period, whereas only 66.7% and 33.3% of the flocks became Campylobacter-positive in spring and winter respectively, at the end of the rearing period. Half of contaminated flocks were infected before chickens have access to the open-air range. Environmental samples, especially the open-air range soil, were found to be Campylobacter-positive before flock infection. The other potential sources of contamination were delivery tray, anteroom floor and water-lines. Other animal productions like cattle on the farm, no applied rodent control, no cleaning and disinfection of water-lines between flocks, no detergent used for cleaning and thinning were recorded as risk factors. In conclusion, the contact with the environment, particularly the access to an open-air range, appeared to be the major way of Campylobacter

    One of the main goals of primary care is providing equitable health-care, meaning equal access, equal treatment and equal outcomes of healthcare for all in equal need. Some studies show that patients from lower socioeconomic groups visit a GP more often, while other studies show that they are more likely to postpone a visit to a GP. In this study, we want to explore within the social group of low-income patients living in Flanders, Belgium, which patients have a higher risk of postponing a visit to a GP. A face-to-face questionnaire was administered among 606 low-income users of Public Social Services. The questionnaire consisted of questions on socioeconomic and demographic characteristics, social networks, health and healthcare use. A multivariate logistic regression model was built to study the relationship between postponing or cancelling a GP visit which respondents thought they needed and variables on health, socio-demographic background. The multivariate regression indicates that depression, self-rated health and trust in the GP independently predict postponing a visit to a GP. Low-income people with a low trust in the GP, people with a poor self-rated health and people suffering from a severe depression are more likely to postpone or cancel a GP visit they thought they needed compared to other people on low incomes. This might indicate that the access to health-care for low-income people might be hindered by barriers which are not directly linked to the cost of the consultation. PMID:23489284

    A temporal trend analysis was performed on antimicrobial resistance data collected over 4 consecutive years (2011-2014) in the official Belgian antimicrobial resistance monitoring programme. Commensal Escherichia coli strains were isolated from faecal samples of four livestock categories (veal calves, young beef cattle, broiler chickens and slaughter pigs) and the trends of resistance profiles were analysed. The resistance prevalence remained high (>50%) during the study period for ampicillin in veal calves and chickens, for ciprofloxacin and nalidixic acid in chickens, for sulfamethoxazole in veal calves, chickens and pigs and for tetracycline in veal calves. Using logistic regression and Generalized Estimating Equation and after p value adjustment for multiple testing (Linear step-up method), statistically significant decreasing temporal trends were observed for several of the 11 tested antimicrobials in several livestock categories: in veal calves (10/11), in chickens (6/11) and in pigs (5/11). A significant increasing trend was observed for the prevalence of resistance to ciprofloxacin in chickens. Multi-resistance, considered as the resistance to at least three antimicrobials of different antibiotic classes, was observed in the four livestock categories but was significantly decreasing in veal calves, chickens and pigs. Overall, the prevalence of resistance and of multi-resistance was lowest in the beef cattle livestock category and highest in broiler chickens. These decreasing temporal trends of antimicrobial resistance might be due to a decrease of the total antimicrobial consumption for veterinary use in Belgium which was reported for the period between 2010 and 2013. The methodology and statistical tools developed in this study provide outputs which can detect shifts in resistance levels or resistance trends associated with particular antimicrobial classes and livestock categories. Such outputs can be used as objective evidence to evaluate the possible

    The City of Menen is a well-outlined residential area located in the neighbourhood of two waste incinerators. The waste incinerators (Menen (Belgium) and Roncq (France)) are in full operation since the eighties. Emission measurements indicate that they fulfil the European Union dioxin emission standard of 0.1 ng TEQ/m{sup 3}. Despite this, new deposition measurements and analysis of milk in this region indicate a high burden of the local environment with dioxin-like polychlorinated biphenyls (dioxin-like PCBs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). It should be noted that formerly the City of Menen was also surrounded by other potential dioxin sources, among them a dye factory, some small illegal cable burning houses, a pressed board manufacturer, and a metal recycling plant. Before 1984, fly ashes of the waste incinerator were locally used as road materials and transported. This could be a secondary source. Additionally the Environmental Inspection has regularly noticed some large open waste fires in this region and follows up the situation. On request of the Public Waste Agency of Flanders (OVAM) an inventory of all dioxin measurements within the city area was made. The ratio of the dioxin-like PCBs compared to the PCDD/Fs in these measurement results was unexpectedly high. As a consequence of this and in order to achieve an optimal risk assessment for the people living in the City of Menen an additional sampling of soil, vegetables and eggs was carried out. This article focuses on the relative amounts of dioxin-like PCBs and PCDD/Fs in the different media and the consequences for the outcome of the risk assessment.

    The actual Brussels' landscape is the result of a progressing anthropisation and urbanisation. Traces of these processes have been conserved in the urban soil. In order to clarify and identify them, a research protocol involving archaeopedology, micro-archaeology and archaeobotany has been developed (DEVOS et al., 2009). Research has so far focussed on the early phases of urban development (10th-13th century AD), which remains a historical poorly documented period. The study of the urban soil and more particularly of the Dark Earth witnesses profound transformations of the environment ensuing human activities such as agriculture, pasturing or quarrying. A second research focus has been the accumulation of ancient pollution in the historical town centre. Ancient texts mention repeatedly nuisances caused by several artisanal activities, as well as the presence of all kind of waste deposits (DELIGNE, 2003). Unfortunately, these sources do not provide reliable data on the importance of the different kinds of pollution. The systematic application of the interdisciplinary research protocol during the follow up of archaeological excavations throughout the historical town centre shows a growing impact of heavy metal pollution for several sites in the upper part of the city while the sites in the lower part of the city are mainly affected by organic pollution, related to agricultural and artisanal activities.

    Various drug residues, pesticides and phthalates are ubiquitous in the environment. Their presence in the environment has attracted considerable attention due to their potential impacts on ecosystem functioning and on public health. In this work, 14 drug residues, 24 pesticides and 6 phthalates have been quantified in three matrices (in the dissolved phase, associated to suspended solid matter (SSM), and in sediment) collected from fifteen watercourses and rivers located in a highly industrialized zone at the cross-border area of Northern France and Belgium. The extractions have been carried out using accelerated solvent extraction (ASE) for solid matrices (SSM and sediment) and using solid phase extraction (SPE) for liquid matrix. The final extract was analyzed using GC-MS technique. Among the three classes of compounds, phthalates have been found at highest level compared to pesticides and drug residues. The Σ6PAE concentrations were ranging from 17.2±2.58 to 179.1±26.9μgL(-1) in dissolved phase, from 2.9±0.4 to 21.1±3.2μgL(-1) in SSM and from 1.1±0.2 to 11.9±1.8μgg(-1)dw in sediment. The Σ14drug residue concentrations were lower than 1.3μgL(-1) in the dissolved phases, lower than 30ngL(-1) associated to SSM and from nondetectable levels to 60.7±9.1ngg(-1)dw in sediment. For pesticides, all compounds were below the LOQ values in dissolved phase and in sediment, and only EPTC could be quantified in SSM.

  9. GIS-BASED location optimization of a biomass conversion plant on contaminated willow in the Campine region (Belgium)

    International Nuclear Information System (INIS)

    The Campine region is diffusely contaminated with heavy metals like cadmium. Since traditional excavation techniques are too expensive, phytoremediation is preferred as a remediation technique. In a previous study, the biomass potential from phytoremediation of contaminated agricultural land in the Campine region in Belgium was assessed. Based on recently upgraded figures of willow potential from phytoremediation on agricultural land in the seven most contaminated municipalities of the Belgian Campine region, the current paper uses GIS-knowledge to investigate which of three previously identified locations is most suitable for a biomass plant, taking into account the spatial distribution of the contaminated willow supply and the total cost of willow transport. Biomass transport distance from the centroid of each contaminated agricultural parcel to each of the three potential biomass plant locations was determined following Euclidian distance calculations and distance calculations over the existing road network. A transport cost model consisting of distance fixed and distance dependent biomass transport costs was developed. Of the locations identified, the Overpelt Fabriek site results in the lowest biomass transport distance and costs. When willow allocation for each parcel occurs based on the nearest potential plant location, transport costs are on average 23% lower than when all biomass is transported to the single Overpelt Fabriek site location. Therefore, when only considering transport costs, installing a smaller plant at each of the three potential plant locations would be less expensive than when installing a single biomass plant at the Overpelt Fabriek site. -- Highlights: ► Overpelt Fabriek site most attractive for time frames considered. ► Average tortuosity factor in Campine region between 1.27 and 1.42. ► Share of willow transport costs in willow supply costs 21%. ► Optimal allocation of willow results in lower transport costs

    SummaryIn order to model the nitrate concentration of the recharge water in a spatially distributed way for the agricultural areas of the Walloon Region of Belgium, the EPIC model was first adapted to the specific soil description by modifying the reservoir sizes. It was also adapted to the regional crop production by modifying classcrop files in relation with observed data (both aerial and underground crop growth, yield) in wheat, sugar beet, and potato fields. As the vadose zone presents a depth between 1.5 and 104 m in this region, new reservoirs were added according to the geological descriptions available. Deep nitrate transfer was validated in a specific site where cropping history was known. Nitrate nitrogen after harvest in the root zone was validated for wheat within different crop rotations using the first results of a nitrate-monitoring program planned by the authorities to test the effectiveness of the mitigation measures in agriculture. This extended model was also linked to a GIS (geographical information system) using 1 km 2-cells. All the required data were rasterised to allow HRU (hydrological response unit) identification within the cells. The cell's daily water flows are weighted flows of each HRU depending on their relative area within the cell. Water balances at catchment scale allow us to validate the calculation. Taking into account the evolution of distributed land use and observed climatic data, we have built maps of fast indicators and long-term indicators. The first map represents nitrate concentration in the water leaving the root zone and the second one represents the time transfer for nitrate from 1.5 m depth to the groundwater table and nitrate concentration in recharge water. These maps constitute major tools for nitrogen management at a regional level.

    In Belgium, where haemophilia affects approximately 1:7000 people (2011), data on patients' quality of life (QoL) is scarce. This project aims to assess physical and mental QoL (P-QoL and M-QoL) simultaneously, and to analyse the influence of different variables on these two aspects of QoL. After Ethics Committee approval, we contacted 84 adult haemophilia A (HA) and haemophilia B (HB) patients, without current inhibitors, on replacement therapy (on-demand or secondary prophylaxis), regularly followed up at our comprehensive treatment centre. Seventy-one (n = 59 HA, n = 12 HB) replied to our questionnaire, which included the SF36v2 QoL assessment forms. We analysed two groups of variables: one including variables previously associated with decreased QoL, and another including variables with unclear impact on QoL (e.g., patients' understanding of haemophilia-related issues, economical concerns). In our population (mean ± SD age: 45.2 ± 14.7 years old), P-QoL appeared more reduced than M-QoL. P-QoL was strongly influenced by the number of arthropathies while M-QoL was primarily affected by patients' concern of personal costs due to haemophilia. Among this latter group, having knowledge of insurance coverage had a positive impact on M-QoL. Scores did not depend on haemophilia type. QoL was impaired in our haemophilia patients. A simultaneous assessment of P-QoL and M-QoL confirmed the benefit of primary prophylaxis in P-QoL, while originally pointing out the major burden of patients' concerns and poor understanding of haemophilia-related economical issues on their M-QoL. This might become a particularly challenging issue in times of financial crisis. PMID:24354566

    A temporal trend analysis was performed on antimicrobial resistance data collected over 4 consecutive years (2011-2014) in the official Belgian antimicrobial resistance monitoring programme. Commensal Escherichia coli strains were isolated from faecal samples of four livestock categories (veal calves, young beef cattle, broiler chickens and slaughter pigs) and the trends of resistance profiles were analysed. The resistance prevalence remained high (>50%) during the study period for ampicillin in veal calves and chickens, for ciprofloxacin and nalidixic acid in chickens, for sulfamethoxazole in veal calves, chickens and pigs and for tetracycline in veal calves. Using logistic regression and Generalized Estimating Equation and after p value adjustment for multiple testing (Linear step-up method), statistically significant decreasing temporal trends were observed for several of the 11 tested antimicrobials in several livestock categories: in veal calves (10/11), in chickens (6/11) and in pigs (5/11). A significant increasing trend was observed for the prevalence of resistance to ciprofloxacin in chickens. Multi-resistance, considered as the resistance to at least three antimicrobials of different antibiotic classes, was observed in the four livestock categories but was significantly decreasing in veal calves, chickens and pigs. Overall, the prevalence of resistance and of multi-resistance was lowest in the beef cattle livestock category and highest in broiler chickens. These decreasing temporal trends of antimicrobial resistance might be due to a decrease of the total antimicrobial consumption for veterinary use in Belgium which was reported for the period between 2010 and 2013. The methodology and statistical tools developed in this study provide outputs which can detect shifts in resistance levels or resistance trends associated with particular antimicrobial classes and livestock categories. Such outputs can be used as objective evidence to evaluate the possible

    Global food safety depends on continuous monitoring of food contaminants such as mycotoxins in cereals and cereal-derived products. Here, we combine this type of investigation with quantitative occurrence data on Fusarium infestation of these products in extensive correlation studies. Finally, this contributes to a thorough understanding of the presence, origin and physiology of Fusarium Head Blight (FHB) related mycotoxins and the correlations within their ranks. Two hundred and thirty-seven samples were analyzed from diverse cereal matrices, representing the most important stages of the cereal food and feed chain in Belgium. Food, feed and non-processed field samples were investigated, with a strong emphasis on whole-grain food products. Two approaches were pursued to estimate the full scope of FHB and its repercussions: UPLC-MS/MS was applied to detect twelve different mycotoxins, and Q-PCR was used to measure the presence of ten Fusarium species. We found that different matrices have different characteristic contamination profiles, and extensive correlation studies identified certain mycotoxins for future assessment (e.g. moniliformin produced by the Fusarium avenaceum/Fusarium tricinctum species group). The investigated harvest year of 2012 yielded many non-processed field materials containing elevated levels of deoxynivalenol (DON), while even in a so-called DON-year less prevalent toxins such as T-2 and HT-2 might be considered problematic due to their consistent co-occurrence with related mycotoxins. Our data illustrate complex interactions between the many Fusarium species that are responsible for FHB and their mycotoxins. Correlation studies demonstrate that consistent co-occurrence of mycotoxins is not to be neglected, and pinpoint issues for future surveillance and legislation.

  14. Schmallenberg virus circulation in culicoides in Belgium in 2012: field validation of a real time RT-PCR approach to assess virus replication and dissemination in midges.

    Directory of Open Access Journals (Sweden)

    Nick De Regge

    Full Text Available Indigenous Culicoides biting midges are suggested to be putative vectors for the recently emerged Schmallenberg virus (SBV based on SBV RNA detection in field-caught midges. Furthermore, SBV replication and dissemination has been evidenced in C. sonorensis under laboratory conditions. After SBV had been detected in Culicoides biting midges from Belgium in August 2011, it spread all over the country by the end of 2011, as evidenced by very high between-herd seroprevalence rates in sheep and cattle. This study investigated if a renewed SBV circulation in midges occurred in 2012 in the context of high seroprevalence in the animal host population and evaluated if a recently proposed realtime RT-PCR approach that is meant to allow assessing the vector competence of Culicoides for SBV and bluetongue virus under laboratory conditions was applicable to field-caught midges. Therefore midges caught with 12 OVI traps in four different regions in Belgium between May and November 2012, were morphologically identified, age graded, pooled and tested for the presence of SBV RNA by realtime RT-PCR. The results demonstrate that although no SBV could be detected in nulliparous midges caught in May 2012, a renewed but short lived circulation of SBV in parous midges belonging to the subgenus Avaritia occured in August 2012 at all four regions. The infection prevalence reached up to 2.86% in the south of Belgium, the region where a lower seroprevalence was found at the end of 2011 than in the rest of the country. Furthermore, a frequency analysis of the Ct values obtained for 31 SBV-S segment positive pools of Avaritia midges showed a clear bimodal distribution with peaks of Ct values between 21-24 and 33-36. This closely resembles the laboratory results obtained for SBV infection of C. sonorensis and implicates indigenous midges belonging to the subgenus Avaritia as competent vectors for SBV.

    2015-01-01

    ORBi, the institutional repository at the University of Liège (ULg), Belgium, is currently the most successful "green OA" tool, with a compliance rate close to 90%. This is due to a strongly enforced institutional mandate which has progressively but quickly led authors to realise all the benefits they could draw from it. A September 2015 survey has demonstrated the popularity of ORBi among the ULg research community. ORBi, le dépôt institutionnel de l'Université de Liège (ULg), Belgique, e...

    The ionospheric behavior over Belgium during the partial solar eclipse of 20 March 2015 is analyzed based on high-resolution solar radio flux, vertical incidence sounding, and GPS TEC measurements. First results of ionosonde-based ionospheric plasma drift and tilt observations are presented and analyzed, including some traveling ionospheric disturbances caused by the eclipse. Also, collocated ionosonde and GPS measurements are used to reconstruct the time evolution of the vertical electron density distribution using the Royal Meteorological Institute (RMI) ionospheric specification system, called Local Ionospheric Electron Density profile Reconstruction (LIEDR).

    A new azole resistance mechanism in Aspergillus fumigatus consisting of a TR46/Y121F/T289A alteration in the cyp51A gene was recently described in the Netherlands. Strains containing these mutations are associated with invasive infection and therapy failure. This communication describes the first case of fatal invasive aspergillosis caused by TR46/Y121F/T289A outside the Netherlands, in the neighboring country of Belgium, suggesting geographical spread. TR46/Y121F/T289A leads to a recognisable phenotypic susceptibility pattern which should trigger cyp51A genotyping to monitor further spread. PMID:23218390

    This work presents preliminary results of nitrous oxide (N2O) fluxes measured by dynamic closed chambers from a fertilized grassland grazed by the Belgian Blue breed of cattle. It is part of a project funded by the public service of Wallonia (SPW-DGARNE), whose objectives are to make a carbon/CO2 balance of the grassland (Jérôme et al., 2013) and to quantify CH4 (Dumortier et al., 2013) and N2O fluxes. The site is located in Dorinne (Dorinne Terrestrial Observatory), Belgium (50° 18' 44" N; 4° 58' 07" E; 248 m al.). It is a permanent grassland of ca. 4.2 ha with a moderate slope of 1 to 2 %. Mineral fertilisation took place in March and May 2012. Two cylindrical chambers of 19,2 cm diameter and 11,5 cm height were placed inside a protected area around a micrometeorological station. An infrared gas analyser (Thermofischer 46i) was used in order to measure the N2O concentrations inside of the chambers, closed by automatically controlled lids and ventilated by a constant air flow of 1liter/min. These devices were completed by adjacent soil humidity and temperature sensors. The first measurement campaign took place during June and July 2012. The chambers were installed in the field and N2O fluxes were followed without manipulation. N2O fluxes were characterised by a background emission (between 2 and 10 ngN.m2s-1) on which intense but time limited peaks (between 50 and 300 ngN.m2s-1) superimposed. Peaks were found to be mainly linked to fertilisation and driven by precipitation. Background fluxes were found to correlate positively with soil temperature. Secondly, a manipulation experiment took place in November 2012: two different fertilizer treatments were applied to the chambers. Doses of respectively 100 and 200 kg N/ha of ammonium nitrate were sprayed in the chambers (equivalent to a 8 mm precipitation). N2O fluxes peaked shortly after fertiliser application (respectively 300 and 550 ngN.m2s-1), as well as after a posterior rain event (respectively 800 and 1500

    From 30 June 2011 to 2 July 2012 PM10 aerosol samples were simultaneously taken every 4th day at four urban background sites in Flanders, Belgium. The sites were in Antwerpen, Gent, Brugge, and Oostende. The PM10 mass concentration was determined by weighing; organic and elemental carbon (OC and EC) were measured by thermal-optical analysis, the wood burning tracers levoglucosan, mannosan and galactosan were determined by gas chromatography/mass spectrometry, 8 water-soluble ions were measured by ion chromatography, and 15 elements were determined by a combination of inductively coupled plasma atomic emission spectrometry and mass spectrometry. The multi-species dataset was subjected to receptor modeling by PMF. The 10 retained factors (with their overall average percentage contributions to the experimental PM10 mass) were wood burning (9.5%), secondary nitrate (24%), secondary sulfate (12.6%), sea salt (10.0%), aged sea salt (19.2%), crustal matter (9.7%), non-ferrous metals (1.81%), traffic (10.3%), non-exhaust traffic (0.52%), and heavy oil burning (3.0%). The average contributions of wood smoke for the four sites were quite substantial in winter and ranged from 12.5 to 20% for the PM10 mass and from 47 to 64% for PM10 OC. Wood burning appeared to be also a notable source of As, Cd, and Pb. The contribution from wood burning to the PM10 mass and OC was also assessed by making use of levoglucosan as single marker compound and the conversion factors of Schmidl et al. (2008), as done in our previous study on wood burning in Flanders (Maenhaut et al., 2012). However, the apportionments were much lower than those deduced from PMF. It seems that the conversion factors of Schmidl et al. (2008) may not be applicable to wood burning in Flanders. From scatter plots of the PMF-derived wood smoke OC and PM versus levoglucosan, we arrived at conversion factors of 9.7 and 22.6, respectively. PMID:27110969

    Amongst today's techniques that are able to produce 3D point clouds, LIDAR and UAV (Unmanned Aerial Vehicle) photogrammetry are probably the most commonly used. Both methods have their own advantages and limitations. LIDAR scans create high resolution and high precision 3D point clouds, but such methods are generally costly, especially for sporadic surveys. Compared to LIDAR, UAV (e.g. drones) are cheap and flexible to use in different kind of environments. Moreover, the photogrammetric processing workflow of digital images taken with UAV becomes easier with the rise of many affordable software packages (e.g. Agisoft, PhotoModeler3D, VisualSFM). We present here a challenging study made at the Rochefort Cave Laboratory (South Belgium) comprising surface and underground surveys. The site is located in the Belgian Variscan fold-and-thrust belt, a region that shows many karstic networks within Devonian limestone units. A LIDAR scan has been acquired in the main chamber of the cave (~ 15000 m³) to spatialize 3D point cloud of its inner walls and infer geological beds and structures. Even if the use of LIDAR instrument was not really comfortable in such caving environment, the collected data showed a remarkable precision according to few control points geometry. We also decided to perform another challenging survey of the same cave chamber by modelling a 3D point cloud using photogrammetry of a set of DSLR camera pictures taken from the ground and UAV pictures. The aim was to compare both techniques in terms of (i) implementation of data acquisition and processing, (ii) quality of resulting 3D points clouds (points density, field vs cloud recovery and points precision), (iii) their application for geological purposes. Through Rochefort case study, main conclusions are that LIDAR technique provides higher density point clouds with slightly higher precision than photogrammetry method. However, 3D data modeled by photogrammetry provide visible light spectral information

    Full Text Available Abstract Background In coming decades the proportion of very elderly people living in the Western world will dramatically increase. This forthcoming "grey epidemic" will lead to an explosion of chronic diseases. In order to anticipate booming health care expenditures and to assure that social security is funded in the future, research focusing on the relationship between chronic diseases, frailty and disability is needed. The general aim of the BELFRAIL cohort study (BFC80+ is to study the dynamic interaction between health, frailty and disability in a multi-system approach focusing on cardiac dysfunction and chronic heart failure, lung function, sarcopenia, renal insufficiency and immunosenescence. Methods/Design The BFC80+ is a prospective, observational, population-based cohort study of subjects aged 80 years and older in three well-circumscribed areas of Belgium. In total, 29 general practitioner (GP centres were asked to include patients aged 80 and older. Only three exclusion criteria were used: severe dementia, in palliative care and medical emergency. Two sampling methods for the recruitment of patients were used. Between November 2, 2008 and September 15, 2009, 567 subjects were included in the BFC80+ study. Every study participant was invited to undergo four study visits. The GP recorded background variables and medical history and performed a detailed anamnesis and clinical examination. The clinical research assistant performed an extensive examination including performance testing, questionnaires and technical examinations. Echocardiography was performed at home by a cardiologist. A blood sample was collected in the morning. Follow-up reporting of hard outcome measures including mortality, hospitalization and morbidity was organized. A second data collection is planned after 18 months. Discussion The BFC80+ was designed to acquire a better understanding of the epidemiology and pathophysiology of chronic diseases in the very elderly

    Full Text Available The constitutional monarchy as an essential ‘modern’ state form of the restoration period was intended to restore order and stability in Europe. In this respect, there is more of a break than continuity between the constitutional model that William I introduced in 1814-1815 and the constitutional monarchy to which Leopold I, the first king of the Belgians, had to subject himself in 1831. The specific authoritarian interpretation that William I gave to his function was one of the factors that helps to explain the Belgian revolution. It is therefore logical that the revolution, as such, produced a constitution that firstly, in general was far more democratic and, secondly, specifically restricted the power of the king. The new Belgian constitutional monarchy of 1830-1831 did not keep William I’s ‘heritage’ intact: onthe contrary, the constitutional definition of kingship in Belgium, for that time, was an ultra-liberal, modern answer to the ‘William I system’. Continuïteit en discontinuïteit van de constitutionele monarchie vanuit een transnationaal perspectief. Nederland-België (1815-1831De constitutionele monarchie moest als een essentieel ‘moderne’ staatsvorm in het restauratietijdperk voor een herstel van orde en stabiliteit zorgen in Europa. Er is op dit punt eerder sprake van een breuk dan van continuïteit tussen het grondwettelijk model dat Willem I in 1814-1815 invoerde in het Verenigd Koninkrijk der Nederlanden en de constitutionele monarchie waaraan Leopold I zich als eerste koning der Belgen in 1831 moest onderwerpen. De specifieke interpretatie en autoritaire invulling die Willem I aan zijn functie gaf, was één van de factoren die de Belgische revolutie mee helpt verklaren. Het is dus logisch dat de revolutie als zodanig een grondwet opleverde die ten eerste in het algemeen veel democratischer was, en ten tweede specifiek de macht van de koning sterk inperkte.

    Full Text Available Abstract Background A growing body of scientific research is suggesting that end-of-life care and decision making may differ between age groups and that elderly patients may be the most vulnerable to exclusion of due care at the end of life. This study investigates age-related disparities in the rate of end-of-life decisions with a possible or certain life shortening effect (ELDs and in the preceding decision making process in Flanders, Belgium in 2007, where euthanasia was legalised in 2002. Comparing with data from an identical survey in 1998 we also study the plausibility of the ‘slippery slope’ hypothesis which predicts a rise in the rate of administration of life ending drugs without patient request, especially among elderly patients, in countries where euthanasia is legal. Method We performed a post-mortem survey among physicians certifying a large representative sample (n = 6927 of death certificates in 2007, identical to a 1998 survey. Response rate was 58.4%. Results While the rates of non-treatment decisions (NTD and administration of life ending drugs without explicit request (LAWER did not differ between age groups, the use of intensified alleviation of pain and symptoms (APS and euthanasia/assisted suicide (EAS, as well as the proportion of euthanasia requests granted, was bivariately and negatively associated with patient age. Multivariate analysis showed no significant effects of age on ELD rates. Older patients were less often included in decision making for APS and more often deemed lacking in capacity than were younger patients. Comparison with 1998 showed a decrease in the rate of LAWER in all age groups except in the 80+ age group where the rate was stagnant. Conclusion Age is not a determining factor in the rate of end-of-life decisions, but is in decision making as patient inclusion rates decrease with old age. Our results suggest there is a need to focus advance care planning initiatives on elderly patients. The

    Objectives To estimate the rate of reporting of euthanasia cases to the Federal Control and Evaluation Committee and to compare the characteristics of reported and unreported cases of euthanasia. Design Cross sectional analysis. Setting Flanders, Belgium. Participants A stratified at random sample was drawn of people who died between 1 June 2007 and 30 November 2007. The certifying physician of each death was sent a questionnaire on end of life decision making in the death concerned. Main outcome measures The rate of euthanasia cases reported to the Federal Control and Evaluation Committee; physicians’ reasons for not reporting cases of euthanasia; the relation between reporting and non-reporting and the characteristics of the physician and patient; the time by which life was shortened according to the physician; the labelling of the end of life decision by the physician involved; and differences in characteristics of due care between reported and unreported euthanasia cases. Results The survey response rate was 58.4% (3623/6202 eligible cases). The estimated total number of cases of euthanasia in Flanders in 2007 was 1040 (95% CI 970 to 1109), thus the incidence of euthanasia was estimated as 1.9% of all deaths (95% CI 1.6% to 2.3%). Approximately half (549/1040 (52.8%, 95% CI 43.9% to 60.5%)) of all estimated cases of euthanasia were reported to the Federal Control and Evaluation Committee. Physicians who perceived their case as euthanasia reported it in 93.1% (67/72) of cases. Cases of euthanasia were reported less often when the time by which life was shortened was less than one week compared with when the perceived life shortening was greater (37.3% v 74.1%; Peuthanasia was more often absent (87.7% v 17.6% verbal request only; Peuthanasia cases is reported to the Federal Control and Evaluation Committee. Most non-reporting physicians do not perceive their act as euthanasia. Countries debating legalisation of euthanasia should simultaneously consider

    Full Text Available Abstract Background Active transportation has the potential to contribute considerably to overall physical activity levels in adults and is likely to be influenced by neighborhood-related built environment characteristics. Previous studies that examined the associations between built environment attributes and active transportation, focused mainly on transport-related walking and were conducted within single countries, limiting environmental variability. We investigated the direction and shape of relationships of perceived neighborhood attributes with transport-related cycling and walking in three countries; and examined whether these associations differed by country and gender. Methods Data from the USA (Baltimore and Seattle, Australia (Adelaide and Belgium (Ghent were pooled. In total, 6,014 adults (20–65 years, 55.7% women were recruited in high-/low-walkable and high-/low-income neighborhoods. All participants completed the Neighborhood Environmental Walkability Scale and the International Physical Activity Questionnaire. Generalized additive mixed models were used to estimate the strength and shape of the associations. Results Proximity to destinations, good walking and cycling facilities, perceiving difficulties in parking near local shopping areas, and perceived aesthetics were included in a ‘cyclability’ index. This index was linearly positively related to transport-related cycling and no gender- or country-differences were observed. The ‘walkability’ index consisted of perceived residential density, land use mix access, proximity of destinations and aesthetics. A non-linear positive relationship with transport-related walking was found. This association was stronger in women than in men, and country-specific associations were identified: the strongest association was observed in Seattle, the weakest in Adelaide. In Ghent, the association weakened at higher levels of walkability. Conclusions For cycling, consistent

    Full Text Available Abstract Background Intimate partner violence (IPV has consistently been found to afflict one in twenty pregnant women and is therefore considered a leading cause of physical injury, mental illness and adverse pregnancy outcome. A general antenatal screening policy has been advocated, though compliance with such guidelines tends to be low. We therefore attempted to identify potential barriers to IPV screening in a context where no guidelines have been instigated yet. Methods Questionnaire-based Knowledge, Attitude, and Practice survey among obstetrician-gynaecologists in Flanders, Belgium (n = 478. Results The response rate was 52.1% (249/478. Gynaecologists prove rather unfamiliar with IPV and therefore largely underestimate the extent of the problem. Merely 6.8% (17/249 of the respondents ever received or pursued any kind of education on IPV. Accordingly they do feel insufficiently skilled to deal with IPV, yet sufficiently capable of recognizing IPV among their patients. Survey participants largely refute the incentive of universal screening in favour of opportunistic screening and do not consider pregnancy as a window of opportunity for routine screening. They do consider screening for IPV as an issue of medical liability and therefore do not suffer from a lack of motivation to screen. In addition, obstetrician-gynaecologists do believe that screening for IPV may be an effective means to counteract abusive behaviours. Yet, their outcome expectancy is weighed down by their perceived lack of self-efficacy in dealing with IPV, by lack of familiarity with referral procedures and by their perceived lack of available referral services. Major external or patient-related barriers to IPV screening included a perceived lack of time and fear of offending or insulting patients. Overall, merely 8.4 % (21/245 of gynaecologists in this survey performed some kind of IPV questioning on a regular basis. Finally, physician education was found to be the

    Belgian potato processors, traders and packers are increasingly working with potato contracts. The close follow up of contracted parcels on the land as well as from above is becoming an important tool to improve the quantity and quality of the potato crop and reduce risks in order to plan the storage, packaging or processing and as such to strengthen the competitiveness of the Belgian potato chain in a global market. At the same time, precision agriculture continues to gain importance and progress. Farmers are obligated to invest in new technologies. Between mid-May and the end of June 2014 potato fields in Gembloux were monitored from emergence till canopy closure. UAV images (RGB) and digital (hemispherical) photographs were taken at ten-daily intervals. Crop emergence maps show the time (date) and degree of crop emergence and crop closure (in terms of % cover). For three UAV flights during the growing season RGB images at 3 cm resolution were processed using a K-means clustering algorithm to classify the crop according to its greenness. Based on the greenness %cover and daily cover growth were derived for 5x5m pixels and 25x25m pixels. The latter resolution allowed for comparison with high resolution satellite imagery. Vegetation indices such as %Cover and LAI were calculated with the Cyclopes algorithm (INRA-EMMAH) from high resolution satellite images (DMC/Deimos, 22m pixel size). DMC based cover maps showed similar patterns as compared with the UAV-based cover maps, and allows for further applications of the data in crop management. Today the use of geo-information by the (private) agricultural sector in Belgium is rather limited, notwithstanding the great benefits this type of information may offer, as recognized by the sector. The iPot project, financed by the Belgian Science Policy Office (BELSPO), aims to provide the Belgian potato sector, represented by Belgapom, with near real time information on field condition (weather-soil) and crop development and

    Different studies demonstrated the dramatic effects of watermills on fluvial geomorphology in the Eastern US. Damming of floodplains and milldam lakes increased sediment deposition. Several authors attribute most of the so called post settlement legacy sediment to those milldam lakes. In Europe the role of milldams in the anthropogenic increased floodplain deposition rates during the last 1000 to 2000 years has gotten little attention until now. Therefore we studied the influence of watermills on Holocene floodplain deposition in the Zwalm catchment, Belgium. The Zwalm River is located in western part of the Belgian loess belt in an undulating landscape that had intensive agriculture for most of the last 2000 years. In total 9 watermills were present along the 17 km long main channel during the 19th century, while many were also present on tributaries. Historical records date several of the mills to the 10th century AD, although they might be older, and most of them remain to some degree active today. The influence of watermills on floodplain deposits was tested through coring transects of the Holocene deposits. Detailed transects were performed pairwise upstream and downstream 5 watermills. Samples were taken for grain size analysis using laser diffraction. A possible influence on floodplain topography was tested on a 5 m resolution DTM. Holocene floodplain architecture is similar to other floodplains in the region: a basal early to mid-Holocene peat and gyttja layer is covered by a fine grained sediment layer of more than 5 m thickness. The change between both can be attributed to increased soil erosion due to human land use, and can be considered to be the local legacy sediment. Comparison of transects upstream and downstream mills shows no significant difference in total Holocene or legacy sediment thickness. Texture analysis indicates that floodplain sediments are significant coarser downstream the mills.F Floodplains are not significant steeper around mills

    The border area between Germany, Belgium, and The Netherlands includes a substantial number of cooperative forms in the urgent medical assistance sector. Collaboration usually takes place in densely populated areas with cities or villages situated on or in proximity to the border. In some regions, definitive borders are not apparent to the extent that inhabitants often times are unaware of their existence. The border may pass directly through a built-up area with intense cross-border activity due to population residency, place of work, shopping, and recreational pursuits. To obtain a deeper insight into cross-border Urgent Medical Assistance (UMA), the Ministry of the Interior and Kingdom Relations (IKR) and the Ministry for Health, Welfare, and Sports (HWS) in The Netherlands commissioned research into cross-border UMA impediments and solutions at administrative, judicial, and operational level. The following central questions were presented for research: (1) What opportunities and impediments are presented in the area of cross-border, urgent medical assistance at administrative, legal, operational, and equipment employable level?; and (2) Which solutions may be submitted to tackle existing impediments? Two techniques were employed to answer the research questions. First, relevant documents were studied from extensive file and literature searches. File and literature search findings subsequently were tested in practice through interviews with relevant experts. Dutch ambulance services provide support to both their Belgian and German counterparts and vice versa. In the instance of cross-border ambulance deployment, relevant assistance services are subject to due observance of various legislations and regulations. Such regulations may restrict effective and efficient deployment of personnel and equipment at critical moments, because regulation discrepancies may arise over ambulance personnel's authorities, ambulance content, and deployment sequence.

    The Badboot (Dutch for swimming pool boat) is a floating swimming pool located in the city center of Antwerp in Belgium. The overall design consists of a recycled ferry boat that serves as a restaurant and next to that a newly built ship that harbours an Olympic size swimming pool, sun decks, locker rooms with showers, and a party space. A major design goal of the project was to make the ship as environmentally friendly as possible. To avoid discharge of contaminated waste water in the Antwerp docks, the ship includes onsite treatment of wastewater in a compact constructed wetland. The treatment wetland system was designed to treat wastewater from visitor locker rooms, showers, toilets, two bars, and the wastewater from the restaurant kitchen. Due to the limited space on board the ship, only 188 m(2) could be allocated to a wetland treatment system. As a result, part of the design included intensification of the wetland treatment process through the use of Forced Bed Aeration, which injects small quantities of air in a very uniform grid pattern throughout the wetland with a mechanical air compressor. The system was monitored between August 2012 and March 2013 (with additional sampling in the autumn of 2014). Flows and loads to the wetland were highly variable, but removal efficiency was extremely high; 99.5 % for chemical oxygen demand (COD), 88.6 % for total nitrogen and 97.2 % for ammonia. The treatment performance was assessed using a first-order, tanks-in-series model (the P-k-C* model) and found to be roughly equivalent to similar intensified wetlands operating in Germany. However, treatment performance was substantially better than data reported on passive wetlands, likely as a result of intensification. Even with mechanically assisted aeration, the total oxygen delivered to the treatment wetlands was insufficient to support conventional nitrification and denitrification, so it is likely that alternate nitrogen removal pathways, such as anammox, are

    Full Text Available Various scientific applications and services increasingly demand real-time information on the effects of space weather on Earth’s atmosphere. In this frame, the Royal Observatory of Belgium (ROB takes advantage of the dense EUREF Permanent GNSS Network (EPN to monitor the ionosphere over Europe from the measured delays in the GNSS signals, and provides publicly several derived products. The main ROB products consist of ionospheric vertical Total Electron Content (TEC maps over Europe and their variability estimated in near real-time every 15 min on 0.5° × 0.5° grids using GPS observations. The maps are available online with a latency of ~3 min in IONEX format at ftp://gnss.oma.be and as interactive web pages at www.gnss.be. This paper presents the method used in the ROB-IONO software to generate the maps. The ROB-TEC maps show a good agreement with widely used post-processed products such as IGS and ESA with mean differences of 1.3 ± 0.9 and 0.4 ± 1.6 TECu respectively for the period 2012 to mid-2013. In addition, we tested the reliability of the ROB-IONO software to detect abnormal ionospheric activity during the Halloween 2003 ionospheric storm. For this period, the mean differences with IGS and ESA maps are 0.9 ± 2.2 and 0.6 ± 6.8 TECu respectively with maximum differences (>38 TECu occurring during the major phase of the storm. These differences are due to the lower resolution in time and space of both IGS and ESA maps compared to the ROB-TEC maps. A description of two recent events, one on March 17, 2013 and one on February 27, 2014 also highlights the capability of the method adopted in the ROB-IONO software to detect in near real-time abnormal ionospheric behaviour over Europe. In that frame, ROB maintains a data base publicly available with identified ionospheric events since 2012.

In this frame, the Royal Observatory of Belgium (ROB) takes advantage of the dense EUREF Permanent GNSS Network (EPN) to monitor the ionosphere over Europe from the measured delays in the GNSS signals, and provides publicly several derived products. The main ROB products consist of ionospheric vertical Total Electron Content (TEC) maps over Europe and their variability estimated in near real-time every 15 min on 0.5° × 0.5° grids using GPS observations. The maps are available online with a latency of ~3 min in IONEX format at ftp://gnss.oma.be and as interactive web pages at http://www.gnss.be/Atmospheric_Maps/ionospheric_maps.php. This paper presents the method used in the ROB-IONO software to generate the maps. The ROB-TEC maps show a good agreement with widely used post-processed products such as IGS and ESA with mean differences of 1.3 ± 0.9 and 0.4 ± 1.6 TECu respectively for the period 2012 to mid-2013. In addition, we tested the reliability of the ROB-IONO software to detect abnormal ionospheric activity during the Halloween 2003 ionospheric storm. For this period, the mean differences with IGS and ESA maps are 0.9 ± 2.2 and 0.6 ± 6.8 TECu respectively with maximum differences (>38 TECu) occurring during the major phase of the storm. These differences are due to the lower resolution in time and space of both IGS and ESA maps compared to the ROB-TEC maps. A description of two recent events, one on March 17, 2013 and one on February 27, 2014 also highlights the capability of the method adopted in the ROB-IONO software to detect in near real-time abnormal ionospheric behaviour over Europe. In that frame, ROB maintains a data base publicly available with identified ionospheric events since 2012.

  19. ADS National Programmes: Belgium

    International Nuclear Information System (INIS)

    The Belgian activities in the field of Accelerator Driven Systems (ADS) are mainly related to the MYRRHA project development. MYRRHA is an accelerator driven, multi purpose fast neutron spectrum facility for R&D, cooled by a lead-bismuth eutectic. SCK•CEN has started the MYRRHA project as a national programme with several national & international bilateral collaboration agreements; the project has now evolved as an European integrated project in the frame of the IPEUROTRANS (European Commission, Sixth Framework Programme). The MYRRHA ‘Draft-2’ predesign file (completed in the early 2005) has been proposed to the partners as a basis for the XT-ADS machine. After a detailed investigation of potential alternatives, the MYRRHA concept (for the subcritical core, the primary coolant system, the accommodation of experimental rigs, the reactor vessel and the spallation target) has been kept with some modifications to achieve the XT-ADS objectives. The most recent version of the XT-ADS design was presented in the 2007 TWG meeting

    Full Text Available The Center of Epidemiologic Studies Depression Scale (CES-D is a commonly used self-report scale to measure depressive symptoms in the general population. In the present study, the Dutch version of the CES-D was administered to a sample of 837 Dutch-speaking adults of Belgium to examine the factor structure of the scale. Using confirmatory factory analysis (CFA, four first-order models and two second-order models were tested, and the second-order factor model with three pairs of correlated error terms provided the best fit to the data. Second, five socio-demographic variables (age, gender, education level, relation status, and family history of depression were included as covariates to the second-order factor model to explore the associations between background characteristics and the latent factor depression using a multiple indicators and multiple causes (MIMIC approach. Age had a significantly negative effect on depression, but the effect was not substantial. Female gender, lower education level, being single or widowed, and having a family history of depression were found to be significant predictors of higher levels of depression symptomatology. Finally, percentile norms on the CES-D raw scores were provided for subgroups of gender by education level for the general Dutch-speaking adult population of Belgium.

  2. The survival of 19th-century scientific optimism: the public discourse on science in Belgium in the aftermath of the Great War (ca. 1919-1930).

    In historiography there is a tendency to see the Great War as marking the end of scientific optimism and the period that followed the war as a time of discord. Connecting to current (inter)national historiographical debate on the question of whether the First World War meant a disruption from the pre-war period or not, this article strives to prove that faith in scientific progress still prevailed in the 1920s. This is shown through the use of Belgium as a case study, which suggests that the generally adopted cultural pessimism in the post-war years did not apply to the public rhetoric of science in this country. Diverse actors -- scientists, industrialists, politicians, the public opinion, and the military staff -- declared a confidence in science, enhanced by wartime results. Furthermore, belief in science in Belgium was not affected by public outcry over the use of mustard gas, unlike in the former belligerent countries where the gas became an unpleasant reminder of how science was used during the war. Even German science with its industrial applications remained the norm after 1918. In fact, the faith in science exhibited during the pre-war years continued to exist, at least until the 1920s, despite anti-German sentiments being voiced by many sections of Belgian society in the immediate aftermath of the war.

  3. Severe acute respiratory infections during the influenza A(H1N1)2009 pandemic in Belgium: first experience of hospital-based flu surveillance

    2010-01-01

    Introduction In September 2009, as part of the surveillance during the Influenza A(2009) pandemic, Bel-gium introduced a web-based surveillance system aimed at recording hospitalisations and deaths attributable to Influenza in real time. Methods We present the web-based application developed for the pandemic as well as a descriptive analysis of Severe Acute Respiratory Infection (SARI) cases reported through this system. Results From 1 September to 31 December 2009, 1723 SARI-related hospitalisations potentially due to influenza were reported in Belgium. The median age of the patients was 29 years (range: < 1 year-99 years). Among SARI-hospitalised patients 68% were aged less than 45 years, 10.6% were vaccinated with the seasonal influenza vaccine and 7.5% with the pandemic influenza vaccine. No deaths were recorded. Conclusions This first experience showed the feasibility of getting real-time information from hospitals during a public health crisis. However, the absence of death detected through the system highlighted the importance of better defining the severity of the hospital cases.

    In this case study, European quality benchmarks were used to explore the contemporary quality of the long-term care provision for older people in the Belgian region of Flanders and the Netherlands following recent policy reforms. Semi-structured qualitative interviews were conducted with various experts on the long-term care provision. The results show that in the wake of the economic crisis and the reforms that followed, certain vulnerable groups of older people in Belgium and the Netherlands are at risk of being deprived of long-term care that is available, affordable and person-centred. Various suggestions were provided on how to improve the quality of the long-term care provision. The main conclusion drawn in this study is that while national and regional governments set the stage through regulatory frameworks and financing mechanisms, it is subsequently up to long-term care organisations, local social networks and informal caregivers to give substance to a high quality long-term care provision. An increased reliance on social networks and informal caregivers is seen as vital to ensure the sustainability of the long-term care systems in Belgium and in the Netherlands, although this simultaneously introduces new predicaments and difficulties. Structural governmental measures have to be introduced to support and protect informal caregivers and informal care networks. PMID:27531456

    Full Text Available Global change—particularly climate change, forest management, and atmospheric deposition—has significantly altered forest growing conditions in Europe. The influences of these changes on beech growth (Fagus sylvatica L. were investigated for the past 80 years in Belgium, using non-linear mixed effects models on ring-width chronologies of 149 mature and dominant beech trees (87–186 years old. The effects of the developmental stage (i.e., increasing tree size were filtered out in order to focus on time-dependent growth changes. Beech radial growth was divided into a low-frequency signal (=growth rate, mainly influenced by forest management and atmospheric deposition, and into a high-frequency variability (≈mean sensitivity, mainly influenced by climate change. Between 1930 and 2008, major long-term and time-dependent changes were highlighted. The beech growth rate has decreased by about 38% since the 1950–1960s, and growth variability has increased by about 45% since the 1970–1980s. Our results indicate that (1 before the 1980s, beech growth rate was not predominantly impacted by climate change but rather by soil alteration (i.e., soil compaction and/or nitrogen deposition; and (2 since the 1980s, climate change induced more frequent and intense yearly growth reductions that amplified the growth rate decrease. The highlighted changes were similar in the two ecoregions of Belgium, although more pronounced in the lowlands than in the uplands.

    On 6 September 2014, the accidental release of 10(13) infectious wild poliovirus type 3 (WPV3) particles by a vaccine production plant in Belgium was reported. WPV3 was released into the sewage system and discharged directly to a wastewater treatment plant (WWTP) and subsequently into rivers that flowed to the Western Scheldt and the North Sea. No poliovirus was detected in samples from the WWTP, surface waters, mussels or sewage from the Netherlands. Quantitative microbial risk assessment (QMRA) showed that the infection risks resulting from swimming in Belgium waters were above 50% for several days and that the infection risk by consuming shellfish harvested in the eastern part of the Western Scheldt warranted a shellfish cooking advice. We conclude that the reported release of WPV3 has neither resulted in detectable levels of poliovirus in any of the samples nor in poliovirus circulation in the Netherlands. This QMRA showed that relevant data on water flows were not readily available and that prior assumptions on dilution factors were overestimated. A QMRA should have been performed by all vaccine production facilities before starting up large-scale culture of WPV to be able to implement effective interventions when an accident happens.

  7. How important are current energy mix choices on future sustainability? Case study: Belgium and Spain-projections towards 2020-2030

    International Nuclear Information System (INIS)

    Despite recent consumption decrease due to recession, European electricity sector is struggling to reach ambitious targets for reductions of greenhouse gas emissions. Our objective is to carry out a macro analysis of the energy mix in two European countries: Belgium and Spain. Life Cycle Assessments are carried for 2005 as well as for seven possible referenced scenarios to reach EU and also national legal objectives at the horizon 2020 and 2030. Ambitious renewable energy sources' deployment plans can decrease impacts on the environment significantly as those sources replace polluting traditional sources, such as coal/lignite, oil or gas. When concentrating on projections for the future in Spain, results show that a mix with little coal and oil replaced by up to 54% of RES-E energy sources could bring environmental benefits with CO2 emissions equivalent around 0.2 kg per kWh produced (compared with 0.54 kg in 2005). In Belgium, all future scenarios presented include more coal and gas with a limited share of RES-E; those mixes present more environmental harmful impacts (up to 0.56 kg CO2 equivalent). This is why RES-E deployment is crucial as long as it is part of an electricity mix with reduced quantities of traditional fossil fuels.

    Full Text Available Abstract Background During a four-year action research project (2003-2007, a program targeting all type 2 diabetes patients was implemented in a well-defined geographical region in Belgium. The implementation of the program resulted in an increase of the overall Assessment of Chronic Illness Care (ACIC score from 1.45 in 2003 to 5.5 in 2007. The aim of the follow-up study in 2008 was to assess the effect of the implementation of Chronic Care Model (CCM elements on the quality of diabetes care in a country where the efforts to adapt primary care to a more chronic care oriented system are still at a starting point. Methods A quasi-experimental study design involving a control region with comparable geographical and socio-economic characteristics and health care facilities was used to evaluate the effect of the intervention in the region. In collaboration with the InterMutualistic Agency (IMA and the laboratories from both regions a research database was set up. Study cohorts in both regions were defined by using administrative data from the Sickness Funds and selected from the research database. A set of nine quality indicators was defined based on current scientific evidence. Data were analysed by an institution experienced in longitudinal data analysis. Results In total 4,174 type 2 diabetes patients were selected from the research database; 2,425 patients (52.9% women with a mean age of 67.5 from the intervention region and 1,749 patients (55.7% women with a mean age of 67.4 from the control region. At the end of the intervention period, improvements were observed in five of the nine defined quality indicators in the intervention region, three of which (HbA1c assessment, statin therapy, cholesterol target improved significantly more than in the control region. Mean HbA1c improved significantly in the intervention region (7.55 to 7.06%, but this evolution did not differ significantly (p = 0.4207 from the one in the control region (7.44 to 6

    Full Text Available Abstract Background Although the incidence of the use of life-ending drugs without explicit patient request has been estimated in several studies, in-depth empirical research on this controversial practice is nonexistent. Based on face-to-face interviews with the clinicians involved in cases where patients died following such a decision in general practice in Belgium, we investigated the clinical characteristics of the patients, the decision-making process, and the way the practice was conducted. Methods Mortality follow-back study in 2005-2006 using the nationwide Sentinel Network of General Practitioners, a surveillance instrument representative of all GPs in Belgium. Standardised face-to-face interviews were conducted with all GPs who reported a non-sudden death in their practice, at home or in a care home, which was preceded by the use of a drug prescribed, supplied or administered by a physican without an explicit patient request. Results Of the 2690 deaths registered by the GPs, 17 were eligible to be included in the study. Thirteen interviews were conducted. GPs indicated that at the time of the decision all patients were without prospect of improvement, with persistent and unbearable suffering to a (very high degree in nine cases. Twelve patients were judged to lack the competence to make decisions. GPs were unaware of their patient's end-of-life wishes in nine cases, but always discussed the practice with other caregivers and/or the patient's relatives. All but one patient received opioids to hasten death. All GPs believed that end-of-life quality had been "improved considerably". Conclusions The practice of using life-ending drugs without explicit patient request in general practice in Belgium mainly involves non-competent patients experiencing persistent and unbearable suffering whose end-of-life wishes can no longer be ascertained. GPs do not act as isolated decision-makers and they believe they act in the best interests of the

    2013-12-01

    Between 2008 and 2010, the Royal Observatory of Belgium received numerous ';Did You Feel It'-reports related to a 2-year lasting earthquake swarm at Court-Saint-Etienne, a small town in a hilly area 20 km SE of Brussels, Belgium. These small-magnitude events (-0.7 ≤ ML ≤ 3.2, n = c. 300 events) were recorded both by the permanent seismometer network in Belgium and by a locally installed temporary seismic network deployed in the epicentral area. Relocation of the hypocenters revealed that the seismic swarm can be related to the reactivation of a NW-SE strike-slip fault at 3 to 6 km depth in the basement rocks of the Lower Palaeozoic London-Brabant Massif. This sequence caused a lot of emotion in the region because more than 60 events were felt by the local population. Given the small magnitudes of the seismic swarm, most events were more often heard than felt by the respondents, which is indicative of a local high-frequency earthquake source. At places where the bedrock is at the surface or where it is covered by thin alluvial sediments ( 30 m). In those river valleys that have a considerable alluvial sedimentary cover, macroseismic intensities are again lower. To explain this variation in macroseismic intensity we present a macroseismic analysis of all DYFI-reports related to the 2008-2010 seismic swarm and a pervasive H/V spectral ratio (HVSR) analysis of ambient noise measurements to model the thickness of sediments covering the London-Brabant Massif. The HVSR method is a very powerful tool to map the basement morphology, particularly in regions of unknown subsurface structure. By calculating the soil's fundamental frequency above boreholes, we calibrated the power-law relationship between the fundamental frequency, shear wave velocity and the thickness of sediments. This relationship is useful for places where the sediment thickness is unknown and where the fundamental frequency can be calculated by H/V spectral ratio analysis of ambient noise. In a

    Dynamic vegetation models (DVM) were initially designed to describe the dynamics of natural ecosystems as a function of climate and soil, to study the role of the vegetation in the carbon cycle. These models are now directly coupled with climate models in order to evaluate feedbacks between vegetation and climate. But DVM characteristics allow numerous other applications, leading to amelioration of some of their modules (e.g., evaluating sensitivity of the hydrological module to land surface changes) and developments (e.g., coupling with other models like agent-based models), to be used in ecosystem management and land use planning studies. It is in this dynamic context about DVMs that we have adapted the CARAIB (CARbon Assimilation In the Biosphere) model. One of the main improvements is the implementation of a crop module, allowing the assessment of climate change impacts on crop yields. We try to validate this module at different scales: - from the plot level, with the use of eddy-covariance data from agricultural sites in the FLUXNET network, such as Lonzée (Belgium) or other Western European sites (Grignon, Dijkgraaf,…), - to the country level, for which we compare the crop yield calculated by CARAIB to the crop yield statistics for Belgium and for different agricultural regions of the country. Another challenge for the CARAIB DVM was to deal with the landscape dynamics, which is not directly possible due to the lack of consideration of anthropogenic factors in the system. In the framework of the VOTES and the MASC projects, CARAIB is coupled with an agent-based model (ABM), representing the societal component of the system. This coupled module allows the use of climate and socio-economic scenarios, particularly interesting for studies which aim at ensuring a sustainable approach. This module has particularly been exploited in the VOTES project, where the objective was to provide a social, biophysical and economic assessment of the ecosystem services in

    Gold remains a rare material during the whole Bronze Age. It is a metal that circulates amongst the elites exclusively. The exchange of gold artefacts over very long distances is fundamental in the build-up of socio-political relations. Fifty artefacts found during subaquatic excavations in the river Lesse in the cave of Han-sur-Lesse have been submitted to quantitative elemental analysis using PIXE, a method never used before on archaeological material found in Belgium. The results show that there are clearly three groups of artefacts. The first one (discs, 'baskets', pearls) proves of local manufacture, as also suggested by the discovery of two ingots. The second one (gilded rings) could have been locally made too, but is a lot less homogeneous. The third one (filigreed and granulated beads or pin's heads) must be imported and most probably originates in the Mediterranean.

  17. Spatial variations and temporal trends between 1994 and 2005 in polychlorinated biphenyls, organochlorine pesticides and heavy metals in European eel (Anguilla anguilla L.) in Flanders, Belgium

    International Nuclear Information System (INIS)

    In Flanders, the northern region of Belgium, European yellow eel muscle tissue was used as an indicator of environmental and potential human dietary exposure by hazardous chemicals of surface waters and sediments. Between 1994 and 2005, over 2800 eel captured at 365 stations were analysed for PCBs, pesticides and heavy metals. Contamination of eel in Flanders fell within the range of reported concentrations in other watersheds of Western Europe. A spatial analysis of the data demonstrated that the variation in pollutant concentration tended towards higher values. This was especially evident for PCBs, lindane, endrin, dieldrin and DDE. The concentration of almost all banned substances decreased significantly during the study period. - Although tissue concentrations of PCBs, pesticides and heavy metals decreased over time, they remain sufficiently high for the consumption of wild captured eel to still be discouraged

    A random sample of visitors of dance events, clubs, and rock festivals in Belgium (Flanders) was selected to complete an anonymous survey regarding their use of "party" drugs (alcohol, cannabis, xtc, cocaine, and amphetamines) and patterns of going out. The results of 670 respondents recruited in 2005 are reported and compared with 2003 for gender and age. Drug use in these nightlife settings is higher than in the general population. In younger age groups, the illegal drug use increases, but it decreases in older age groups. This might be linked to more responsibilities. Men still use drugs more often than women, but the gender differences seem to decrease. The changing role of women in society could be an explanation for this evolution. Limitations and implications of this research are discussed.

    Full Text Available This article will try to correct the ‘modernist myth’, dating the ‘discovery’ of African ‘art’ after 1900, by looking at Belgium and its colony at the end of the 19th century. Although Africans themselves were of course the first to appreciate the beauty of their own objects, not only European artists, but also colonials, scientists and museum curators became fascinated by African artists and their work, including not only sculpture, but also material culture, drawings, architecture, music and dance. The article will trace how African utensils became exhibited as ethnographical specimens and art objects during World Exhibitions and in the (Belgian Congo Museum in Tervuren.

    International Nuclear Information System (INIS)

    The objective of our study was to determine the trace metal accumulation rates in the Misten bog, Hautes-Fagnes, Belgium, and assess these in relation to established histories of atmospheric emissions from anthropogenic sources. To address these aims we analyzed trace metals and metalloids (Pb, Cu, Ni, As, Sb, Cr, Co, V, Cd and Zn), as well as Pb isotopes, using XRF, Q-ICP-MS and MC-ICP-MS, respectively in two 40-cm peat sections, spanning the last 600 yr. The temporal increase of metal fluxes from the inception of the Industrial Revolution to the present varies by a factor of 5–50, with peak values found between AD 1930 and 1990. A cluster analysis combined with Pb isotopic composition allows the identification of the main sources of Pb and by inference of the other metals, which indicates that coal consumption and metallurgical activities were the predominant sources of pollution during the last 600 years. -- Highlights: •Study of trace metals and metalloids in two cores from Belgian peat bog. •Reconstruction of trace metals and metalloids deposition over last 600 years. •Maximum trace metals accumulation rates are recorded between 1930 and 1990 AD. •A cluster analysis combined with Pb isotopic composition used to identify the main sources of Pb and by inference the other metals. •The predominant anthropogenic trace metals sources were consumption and metallurgical activities. -- In this study we used trace metals concentrations and fluxes from two cores sampled in a Belgium bog to document with high resolution the history of trace metals deposition over the last 600 years

    Active monitoring of avian influenza (AI) viruses in wild birds was initiated in Belgium in 2005 in response to the first highly pathogenic avian influenza (HPAI) H5N1 outbreaks occurring in Europe. In Belgium, active wild bird surveillance that targeted live-ringed and hunter-harvested wild birds was developed and maintained from 2005 onward. After one decade, this program assimilated, analyzed, and reported on over 35,000 swabs. The 2009-2014 datasets were used for the current analysis because detailed information was available for this period. The overall prevalence of avian influenza (AI) in samples from live-ringed birds during this period was 0.48% whereas it was 6.12% in hunter-harvested samples. While the ringing sampling targeted a large number of bird species and was realized over the years, the hunting sampling was mainly concentrated on mallard (Anas platyrhynchos) during the hunting season, from mid-August to late January. Even when using just AI prevalence for live-ringed A. platyrhynchos during the hunting season, the value remained significantly lower (2.10%) compared to that detected for hunter-harvested mallards. One explanation for this significant difference in viroprevalence in hunter-harvested mallards was the game restocking practice, which released captive-bred birds in the wild before the hunting period. Indeed, the released game restocking birds, having an AI-naïve immune status, could act as local amplifiers of AI viruses already circulating in the wild, and this could affect AI epidemiology. Also, the release into the wild of noncontrolled restocking birds might lead to the introduction of new strains in the natural environment, leading to increased AI presence in the environment. Consequently, the release of naïve or infected restocking birds may affect AI dynamics.

    Active monitoring of avian influenza (AI) viruses in wild birds was initiated in Belgium in 2005 in response to the first highly pathogenic avian influenza (HPAI) H5N1 outbreaks occurring in Europe. In Belgium, active wild bird surveillance that targeted live-ringed and hunter-harvested wild birds was developed and maintained from 2005 onward. After one decade, this program assimilated, analyzed, and reported on over 35,000 swabs. The 2009-2014 datasets were used for the current analysis because detailed information was available for this period.

    Full Text Available Abstract Background Guidelines established for the treatment of HIV-1 infection and genotype interpretation do not apply for HIV-2. Data about antiretroviral (ARV drug efficacy and resistance mutations is scarce. Methods Clinical data about HIV-2 infected patients in Belgium and Luxembourg were collected and the effect of ARV therapy on plasma viral load and CD4 counts were analysed. Viral RNA encoding for protease (PR and reverse transcriptase (RT from ARV-naïve and treated patients were sequenced. Results Sixty-five HIV-2 infected patients were included in this cohort. Twenty patients were treated with 25 different ARV combinations in a total of 34 regimens and six months after the start of ARV therapy, only one third achieved viral load suppression. All of these successful regimens bar one contained protease inhibitors (PIs. Mean CD4 gains in the group of viral load suppressors and the group of patients treated with PI-containing regimens were respectively significantly higher than in the group of non-suppressors and the group of PI-sparing regimens. The most frequent mutations selected under therapy (compared to HIV-2 ROD were V71I, L90M and I89V within PR. Within RT, they were M184V, Q151M, V111I and K65R. All of these mutations, except K65R and M184V, were also found in variable proportions in ARV-naïve patients. Conclusion Despite a high rate of ARV treatment failure, better virological and immunological results were achieved with PI-containing regimens. The analysis of polymorphic positions and HIV-2 specific mutations selected during therapy showed for the first time that transmission of drug resistant viruses has occurred in Belgium and Luxembourg. The high heterogeneity in ARV combinations reflects a lack of guidelines for the treatment of HIV-2 infection.

    This venue-based, cross-sectional study reports on human immunodeficiency virus (HIV) prevalence and behaviour of 649 men who have sex with men (MSM) in Antwerp and Ghent, Flanders, Belgium, from October 2009 to March 2010. Using time-location sampling, we found that HIV prevalence in MSM who attended different types of venue ranged from a high of 14.5% (95% CI: 8.9–20.1; n=22 in cruising venues to 4.9% (95% CI: 1.9–7.9; n=10) in more general gay venues to 1.4% (95% CI: 0.0–3.6; n=3) at younger MSM venues. Of those who tested HIV positive (n=35, five were unaware of their HIV status or self-reported as being HIV negative. One in five respondents were of non-Belgian nationality. The results showed relatively high rates of testing for HIV (52.2%; 95 % CI: 47.8–56.2; n=288) and other sexually transmitted infections (STIs) (57.4%; 95% CI: 52.6–62.0; n=248) in the last 12 months. A majority of the men (n=233) used condoms consistently during their last anal sexual contact with a casual partner; however, HIV-positive men who were aware of their serostatus (n=30) reported less condom use with casual partners. This is the first such study in Belgium and the results constitute the evidence base for local, targeted interventions. Furthermore, our findings underscore the need for European cross-border cooperation to prevent HIV infection and other STIs among MSM. PMID:21794222

    There exists a large discrepancy between the rural and urban land cover in terms of soil water, aerodynamical, thermal and radiative characteristics, and anthropogenic heat. This results in urban-scale meteorological features such as the urban heat island, reduced wind speed and the city breeze. Some of these effects have a considerable impact on human health in cities when the nocturnal cooling is reduced during heat waves or when air quality is affected during smog episodes. The question rises what impact does urban climate have on air quality in cities. The Regional climate model COSMO-CLM updated with the urban parameterization (TERRA_MLU) and the air-quality AURORA (VITO NV, Belgium) are used to quantify and understand the interactions between (urban) climate and air quality on different scales. COSMO-CLM is currently cascade-nested inside ECMWF 12.5km analysis up to a horizontal resolution of 1km over Antwerp (Belgium). The urban parameterization TERRA_MLU is implemented in COSMO-CLM using a tile approach in which the urban surface can coexist with the natural area in one grid-cell. The inclusion of anthropogenic heat is based on country-specific data of energy consumption downscaled with population density and urbanization. Meteorological model data from COSMO-CLM is used as forcing for the air-quality model AURORA. Results, in particular the urban heat island effect, are evaluated with urban/rural meteorological measurements in Antwerp, Ghent and Brussels starting from 2012. It is investigated whether air-quality modeling can be improved when forcing AURORA with (urban) microscale meteorological data from COSMO-CLM rather than with coarser meteorological data from ECMWF. Therefore each nesting step of COSMO is subsequently used as input for the air-quality model. In order to set priorities for the improvement of air-quality modelling in the future, the relative importance of orography, urban climate and the impact of uncertainty in pollutent emissions to

    Recent research clearly show that climate modelling at high resolution - which resolve the deep convection, the detailed orography and land-use including urbanization - leads to better modelling performance with respect to temperatures, the boundary-layer, clouds and precipitation. The increasing computational power enables the climate research community to address climate-change projections with higher accuracy and much more detail. In the framework of the CORDEX.be project aiming for coherent high-resolution micro-ensemble projections for Belgium employing different GCMs and RCMs, the KU Leuven contributes by means of the downscaling of EC-EARTH global climate model projections (provided by the Royal Meteorological Institute of the Netherlands) to the Belgian domain. The downscaling is obtained with regional climate simulations at 12.5km resolution over Europe (CORDEX-EU domain) and at 2.8km resolution over Belgium (CORDEX.be domain) using COSMO-CLM coupled to urban land-surface parametrization TERRA_URB. This is done for the present-day (1975-2005) and future (2040 → 2070 and 2070 → 2100). In these high-resolution runs, both GHG changes (in accordance to RCP8.5) and urban land-use changes (in accordance to a business-as-usual urban expansion scenario) are taken into account. Based on these simulations, it is shown how climate-change statistics are modified when going from coarse resolution modelling to high-resolution modelling. The climate-change statistics of particular interest are the changes in number of extreme precipitation events and extreme heat waves in cities. Hereby, it is futher investigated for the robustness of the signal change between the course and high-resolution and whether a (statistical) translation is possible. The different simulations also allow to address the relative impact and synergy between the urban expansion and increased GHG on the climate-change statistics. Hereby, it is investigated for which climate-change statistics the

    The objective of this study was to assess the in vitro antimicrobial susceptibility of 73 isolates of Mycoplasma bovis isolated from milk of dairy cattle herds of Belgium, Germany, and Italy. Minimal inhibitory concentration (MIC) values were determined by the microbroth dilution method for the following antimicrobials: erythromycin, spiramycin, tilmicosin, tylosin, lincomycin, enrofloxacin, doxycycline, oxytetracycline, florfenicol, and tiamulin. Macrolides, florfenicol, oxytetracycline, and enrofloxacin, were chosen because they represent antimicrobials families commonly used in several countries for treatment of M. bovis, and their MIC values in cattle population are reported in several studies, allowing a comparison with previous data. Doxycycline and tiamulin were selected to assess the susceptibility of M. bovis to new antimicrobials, because they are not registered in the European Union for the treatment of dairy cattle. Among the agents of the different antimicrobial classes, the macrolides showed the highest concentration to inhibit 90% of isolates (MIC90), all above the highest concentration tested: >8μg/mL for erythromycin, >16μg/mL for spiramycin, and >32μg/mL for tilmicosin and tylosin. Also the MIC90 of lincomycin was above the highest concentration tested (>32μg/mL), but the distribution of the MIC values was almost perfectly bimodal: 41 isolates had a MIC ≤0.5μg/mL and 30 isolates >32μg/mL. Oxytetracycline had a 2-fold higher concentration to inhibit 50% of isolates (2 vs. 0.5μg/mL) and 1-fold higher MIC90 (4 vs. 2μg/mL) than doxycycline. Enrofloxacin and florfenicol had both a MIC90 of 2μg/mL, whereas tiamulin had a MIC90 of 0.5μg/mL. Significant differences on the MIC values were found among the 3 countries for several antimicrobials: compared with Germany, Belgium and Italy showed significantly higher MIC for lincomycin, spiramycin, and tylosin, and lower for oxytetracycline and florfenicol. The Belgian isolates showed the lowest MIC

    In Belgium, several researchers have been highly active in developing pinhole tomo-scintigraphy and have sometimes made a pioneer work. Their contributions concern as well the methodology of the technique as its applications to human and small animals. Reconstruction algorithms, of analytic and iterative type, have been developed and validated. They can reconstruct data obtained along circular, half-circular and non-circular acquisition orbits, the camera head being eventually tilted. A very performing method has been elaborated to determine the seven geometric parameters of the acquisition that are needed for an optimal reconstruction. The use of pinhole tomo-scintigraphy for thyroid exploration seems to be born in Belgium and a few validation studies were conducted in the country. Potentials of pinhole tomography application to parathyroid or bone scintigraphy have also been considered. Finally, some research groups are using pinhole tomo-scintigraphy for small animal studies.

    Television (TV) cooking shows have evolved from focusing on educating to focusing on entertaining, as well. At present, educational TV cooking shows focus on the transfer of cooking knowledge and skills, whereas edutainment TV cooking shows focus on entertaining their viewers. Both types of shows are ongoing success stories. However, little is known regarding the shows' links with the cooking and eating habits of their audiences. Therefore, the current study investigates the relationship between watching an educational or edutainment TV cooking show and one's cooking and eating habits. Given public health concerns regarding the decline in cooking behaviors and the simultaneous increase in caloric intake from food outside the home, this study suggests a promising intervention. The results of a cross-sectional survey in Belgium (n = 845) demonstrate that the audiences of educational and edutainment TV cooking shows do not overlap. Although there is little connection between watching specific shows and eating behavior, the connection between watching shows and cooking behaviors varies across gender and age lines. Behaviors also differ depending on whether the viewer is watching an educational or edutainment cooking show. For example, men of all ages appear to cook more often if they watch an educational show. However, only older men (above 38 years) seem to cook more often if they watch an edutainment TV show. The results demonstrate that the relationship between watching TV cooking shows and cooking habits warrants further investigation. PMID:26485291

    Full Text Available The current dynamics of change, including climate change, resource depletion, energy transition, internet of things, etc. will have substantial impacts on the functioning of contemporary business models. Most firms and companies, however, still largely focus on efficiency strategies leading to sub-optimal solutions (reducing bad impact, rather than radically changing their business model to develop new transaction models more appropriate for today’s world (doing better things. However, persistent sustainability issues arising from our changing societal systems, require more radical and structural changes both within and between organizations to change the way we do business. There is limited empirically established research literature on how businesses can be more proactive in this regard and how they can move beyond “management of unsustainability”. In this paper, we present a transformative business model innovation approach inspired by transition theory combining elements of systems thinking, value-inspired envisioning, reflexive design and co-creation that was pioneered for a consortia of reuse centers in the province of Limburg, Belgium. We demonstrate that this approach contributed to the development of new business model concepts, was conducive for mobilizing support and resources to ensure follow up activity and holds potential to promote a more proactive role for businesses as agents of transformative change.

    Full Text Available Comparison of computation time between single-trait and multiple-trait evaluations showed that with the use of the canonicat transformation associated with multiple diagonalization of (covariance matrices, multiple-trait analysis for milk, fat and protein yields is not more expensive than three single-trait analyzes. Rank correlations between breeding values for 54,820 cows with records (for their 1,406 sires estimated with the single-trait and multiple-trait models were over .98 (.99 in fat yield and over .99 (.99 in milk and protein yields. The relative gain expressed as reduction in mean prediction error variance was 3% (1% in milk yield, 6% (3% in fat yield, and .4% (.2% in protein yield for cows (for sires. Relative genetic gains were 3% (1%, 6% (2% and .5% (.2% respectively in milk, fat and protein yields for cows (for sires. The use of multiple-trait models bas therefore the advantages of improved precision and reduced selection bics. Multiple-trait analysis could be extended for the analyzes of test-day records. Results show that this or similar multiple-trait animal model could be implemented immediately in Belgium at low computing cost, using the proposed algorithme and could be the first step to new, more advanced evaluation methods.

    The nature and causes of the disappearance of Neanderthals and their apparent replacement by modern humans are subjects of considerable debate. Many researchers have proposed biologically or technologically mediated dietary differences between the two groups as one of the fundamental causes of Neanderthal disappearance. Some scenarios have focused on the apparent lack of plant foods in Neanderthal diets. Here we report direct evidence for Neanderthal consumption of a variety of plant foods, in the form of phytoliths and starch grains recovered from dental calculus of Neanderthal skeletons from Shanidar Cave, Iraq, and Spy Cave, Belgium. Some of the plants are typical of recent modern human diets, including date palms (Phoenix spp.), legumes, and grass seeds (Triticeae), whereas others are known to be edible but are not heavily used today. Many of the grass seed starches showed damage that is a distinctive marker of cooking. Our results indicate that in both warm eastern Mediterranean and cold northwestern European climates, and across their latitudinal range, Neanderthals made use of the diverse plant foods available in their local environment and transformed them into more easily digestible foodstuffs in part through cooking them, suggesting an overall sophistication in Neanderthal dietary regimes.

    Due to their probable role in the spread of Asian highly pathogenic avian influenza (HPAI) H5N1 virus, and in order to explore its implication in the low pathogenic avian influenza (LPAI) virus epidemiology, mute swans represent one particular wild bird species specifically targeted in the avian influenza (AI) surveillance elaborated in Belgium. A total of 640 individual mute swans have been sampled during a 4-yr AI surveillance program (2007-2010) to determine the AI seroprevalence and viroprevalence in this species; all were analyzed through age, temporal, and habitat (flowing and stagnant water) factors. Using a nucleoprotein (NP)-based ELISA, a global antibody prevalence of 35% has been found and was characterized by two peaks in the winter and the summer that might be indicative of a greater LPAI virus circulation in the autumn than in the spring. A significantly higher antibody prevalence was detected in adult swans (53.8%) as compared to juveniles (15.5%). In contrast, a low prevalence of infection (2.7%) was found, mainly in juvenile mute swans and only during the autumn migration period. Interestingly, an impact of water habitat was observed based on the comparison of the antibody prevalence and prevalence of infection from swan populations living on stagnant water vs. flowing water, suggesting that stagnant water provides a more-favorable environment for LPAI persistence and transmission.

    An ASM2da model of the full-scale waste water plant of Bree (Belgium) has been made. It showed very good correlation with reference operational data. This basic model has been extended to include an accurate calculation of environmental footprint and operational costs (energy consumption, dosing of chemicals and sludge treatment). Two optimisation strategies were compared: lowest cost meeting the effluent consent versus lowest environmental footprint. Six optimisation scenarios have been studied, namely (i) implementation of an online control system based on ammonium and nitrate sensors, (ii) implementation of a control on MLSS concentration, (iii) evaluation of internal recirculation flow, (iv) oxygen set point, (v) installation of mixing in the aeration tank, and (vi) evaluation of nitrate setpoint for post denitrification. Both an environmental impact or Life Cycle Assessment (LCA) based approach for optimisation are able to significantly lower the cost and environmental footprint. However, the LCA approach has some advantages over cost minimisation of an existing full-scale plant. LCA tends to chose control settings that are more logic: it results in a safer operation of the plant with less risks regarding the consents. It results in a better effluent at a slightly increased cost.

    Abstract Fly larvae living on dead corpses can be used to estimate post-mortem intervals. The identification of these flies is decisive in forensic casework and can be facilitated by using DNA barcodes provided that a representative and comprehensive reference library of DNA barcodes is available. We constructed a local (Belgium and France) reference library of 85 sequences of the COI DNA barcode fragment (mitochondrial cytochrome c oxidase subunit I gene), from 16 fly species of forensic interest (Calliphoridae, Muscidae, Fanniidae). This library was then used to evaluate the ability of two public libraries (GenBank and the Barcode of Life Data Systems – BOLD) to identify specimens from Belgian and French forensic cases. The public libraries indeed allow a correct identification of most specimens. Yet, some of the identifications remain ambiguous and some forensically important fly species are not, or insufficiently, represented in the reference libraries. Several search options offered by GenBank and BOLD can be used to further improve the identifications obtained from both libraries using DNA barcodes. PMID:24453564

    Between 2010 and 2014 several spoilage cases in Belgium occurring in retail foodstuffs prior to the end of shelf-life have been reported to our laboratory. Overall, seven cases involved strictly psychrotrophic lactic acid bacteria (LAB) contamination in packaged and chilled-stored food products. The products derived either from recalls of entire production batches or as specimens of sporadic spoilage manifestations. Some of these samples were returned to the manufacturing companies by consumers who observed the alterations after purchasing the products. The products covered a wide range of foodstuffs (i.e. meat, dairy, vegetable, egg products and composite food) and denoted different spoilage defects. However, the microbiota determined by means of 16S rRNA gene high-throughput sequencing analysis underpin few LAB genera (i.e. Leuconostoc, Lactobacillus, Weissella and Lactococcus), which are frequently encountered nowadays as specific spoilage organisms (SSO) albeit overlooked by mesophilic enumeration methods due to their strictly psychrotrophic character. The present study confirms the spreading of psychrotrophic LAB in Belgian food processing environments leading to unexpected spoilage, corroborating their spoilage dynamics and prevalence in all kinds of packaged and refrigerated foodstuffs in Northern Europe.

    Since about twenty-five years, we observe important transformations of the socio-economic structures of our society, modifying the main references which reign over the social structures and thus over the medical world. As a result, we observe a social syndrome which we can define as a divorce between the medical world and the society. The consequences of this phenomenon can constitute a real danger for the whole society; nevertheless, actually we can still consider that Belgium can assure a very high level of medical care for the greatest part of the population for a really social prize. The main "clinical signs" of this divorce are mentioned and analyzed, the deeper reasons of them as well. Among them, we cite the recent law about the quite exclusive rights of the patients, an incoherent legislation concerning medical activities, the hostility of the world of media against the physicians, the insuffiencies to finance health care and the attacks against several medical organizations and--at least--the fact to give more and more preference to the non-scientific parallel medicine. This whole social process should be kept back because this divorce is not only an economical problem, but rather a question of humanism and of social culture.

    In order to reduce the health risks associated with historically enriched metal smelting sites in Flanders (Belgium), the capacities of a non-beringite cyclonic ash and commercial Na-silicates to fix metals and create conditions to restore vegetation cover were evaluated and compared to lime and H{sub 3}PO{sub 4}. All tested amendments reduced Ca(NO{sub 3}){sub 2}-extractable soil metal concentrations and reduced metal uptake in Agrostis capillaris seedlings. Sodium released by Na-silicates was possibly toxic to bean plants while an isotopic dilution technique revealed that metals were only weakly sorbed by silicates (i.e. reversible sorption). Cyclonic ash appeared more efficient than lime in both reducing oxidative stress in beans and Zn, Cu and Pb uptake in grasses. The metal fixing mechanism for both amendments appeared similar (i.e. irreversible fixation at constant pH), in contrast to H{sub 3}PO{sub 4} where at least part of the immobilised Cd was irreversibly fixed across a range of pH. - Metal immobilising capacities of Na-silicates are weak, while the active mechanism of cyclonic ash is the same as lime.

    The strategic importance of ecosystem service valuation as an operational basis for policy decisions on natural restoration has been increasingly recognized in order to align the provision of ecosystem services with the expectation of human society. The contingent valuation method (CVM) is widely used to quantify various ecosystem services. However, two areas of concern arise: (1) whether people value specific functional ecosystem services and overlook some intrinsic aspects of natural restoration, and (2) whether people understand the temporal dimension of ecosystem services and payment schedules given in the contingent scenarios. Using a peri-urban riparian meadow restoration project in Flanders, Belgium as a case, we explored the impacts of residents' perceived importance of various ecosystem services and stated financial constraints on their willingness-to-pay for the proposed restoration project employing the CVM. The results indicated that people tended to value all the benefits of riparian ecosystem restoration concurrently, although they accorded different importances to each individual category of ecosystem services. A longer payment scheme can help the respondents to think more about the flow of ecosystem services into future generations. A weak temporal embedding effect can be detected, which might be attributed to respondents' concern about current financial constraints, rather than financial bindings associated with their income and perceived future financial constraints. This demonstrates the multidimensionality of respondents' financial concerns in CV. This study sheds light on refining future CV studies, especially with regard to public expectation of ecosystem services and the temporal dimension of ecosystem services and payment schedules.

    Zinc ashes, muffle furnace fragments and lead slags from non-ferrous industries were applied to pave roads in the North of Belgium. From an inventory it appeared that there are at least 490 km of such roads. In our survey the materials on these roads were characterised. The total metal concentration, the availability and the leaching as a function of time were determined. It appeared that these materials contain high concentrations of heavy metals, some of which are readily available. The high leaching of some metals makes them as such unsuitable as secondary construction material. Methods for the application of these materials for road construction were examined where the materials replaced part of the sand and gravel fraction in lean concrete and in bituminous mixtures, or where they replaced the sand in sand-cement mixtures, all these to be used for road foundations, cycle tracks, etc. When lead slags were applied in lean concrete, a material was obtained complying with the standards for secondary construction materials and with sufficient compressive strength for road foundations. When zinc ashes or muffle fragments were used to replace sand in sand-cement mixtures, again a suitable construction material was obtained. The other combinations tried out were rather unsuccessful, because of high metal leaching and/or poor compressive strength.

    Liver and muscle samples from 7 species of aquatic and terrestrial predatory birds from Flanders (Belgium) were analysed for polychlorinated biphenyls (PCBs), polybrominated diphenylethers (PBDEs) and organochlorine pesticides (OCPs). PCBs were the predominant compounds in our samples, which showed highest concentrations in the liver of barn owl (Tyto alba) and sparrowhawk (Accipiter nisus) (up to 1000 {mu}g/g lipid weight). PBDEs could be determined in most samples at lower concentrations than PCBs (up to 64 {mu}g/g lipid in sparrowhawk liver). Sparrowhawks had the highest levels of hexachlorobenzene, DDTs and PBDEs. In contrast, kestrels (Falco tinnunculus) had relatively low levels of most measured organochlorines. BDE 47 was the most abundant congener in heron (Ardea cinerea) and grebe (Podiceps cristatus), while BDE 47, 99 and 153 were equally important in the terrestrial species. BDE 183 and BDE 209 were only measured in the terrestrial birds. These results indicate that terrestrial birds may be more exposed to higher brominated BDE congeners than aquatic species. - Aquatic and terrestrial predatory birds show different accumulation profiles of PBDEs.

    Full Text Available Abstract Background In Belgium, bladder cancer is the fifth most common cancer in males (5.2% and the sixth most frequent cause of death from cancer in males (3.8%. Previous epidemiological studies have consistently reported that selenium concentrations were inversely associated with the risk of bladder cancer. This suggests that selenium may also be suitable for chemoprevention of recurrence. Method The SELEBLAT study opened in September 2009 and is still recruiting all patients with non-invasive transitional cell carcinoma of the bladder on TURB operation in 15 Belgian hospitals. Recruitment progress can be monitored live at http://www.seleblat.org. Patients are randomly assigned to selenium yeast (200 μg/day supplementation for 3 years or matching placebo, in addition to standard care. The objective is to determine the effect of selenium on the recurrence of bladder cancer. Randomization is stratified by treatment centre. A computerized algorithm randomly assigns the patients to a treatment arm. All study personnel and participants are blinded to treatment assignment for the duration of the study. Design The SELEnium and BLAdder cancer Trial (SELEBLAT is a phase III randomized, placebo-controlled, academic, double-blind superior trial.

    Full Text Available On 8 November 1983 an earthquake of magnitude 4.6 damaged more than 16 000 buildings in the region of Liège (Belgium. The extraordinary damage produced by this earthquake, considering its moderate magnitude, is extremely well documented, giving the opportunity to compare the consequences of a recent moderate earthquake in a typical old city of Western Europe with scenarios obtained by combining strong ground motions and vulnerability modelling. The present study compares 0.3 s spectral accelerations estimated from ground motion prediction equations typically used in Western Europe with those obtained locally by applying the statistical distribution of damaged masonry buildings to two fragility curves, one derived from the HAZUS programme of FEMA (FEMA, 1999 and another developed for high-vulnerability buildings by Lang and Bachmann (2004, and to a method proposed by Faccioli et al. (1999 relating the seismic vulnerability of buildings to the damage and ground motions. The results of this comparison reveal good agreement between maxima spectral accelerations calculated from these vulnerability and fragility curves and those predicted from attenuation law equations, suggesting peak ground accelerations for the epicentral area of the 1983 earthquake of 0.13–0.20 g (g: gravitational acceleration.

    Due to common belief that regions under temperate climate are not affected by (meteorological and groundwater) drought, these events and their impacts remain poorly studied: in the GroWaDRISK, we propose to take stock of this question. We aim at providing a better understanding of the influencing factors (land use and land cover changes, water demand and climate) and the drought-related impacts on the environment, water supply and agriculture. The study area is located in the North-East of Belgium, corresponding approximatively to the Dijle and Demer catchments. To establish an overview of the groundwater situation, we assess the system input: the recharge. To achieve this goal, two models, B-CGMS and WetSpass are used to evaluate the recharge, respectively, over agricultural land and over the remaining areas, as a function of climate and for various land uses and land covers. B-CGMS, which is an adapted version for Belgium of the European Crop Growth Monitoring System, is used for assessing water recharge at a daily timestep and under different agricultural lands: arable land (winter wheat, maize...), orchards, horticulture and floriculture and for grassland. B-CGMS is designed to foresee crop yield and obviously it studies the impact of drought on crop yield and raises issues for the potential need of irrigation. For both yields and water requirements, the model proposes a potential mode, driven by temperature and solar radiation, and a water-limited mode for which water availability can limit crop growth. By this way, we can identify where and when water consumption and yield are not optimal, in addition to the Crop Water Stress Index. This index is calculated for a given crop, as the number of days affected by water stress during the growth sensitive period. Both recharge and crop yield are assessed for the current situation (1980 - 2012), taking into account the changing land use/land cover, in terms of areas and localization of the agricultural land and where

    The area of Sandy Flanders, situated between the North Sea coast and the lower course of the Scheldt River in NW Belgium, is a relatively flat and low-lying area situated at the southern limit of the lowland cover sand region of the NW European plain. During the Late Pleniglacial and the Late Glacial, numerous, generally small but elongated sand dunes, shallow lakes and wet depressions were formed. During the last three decades intense archaeological prospection has taken place in this region, which is now one of the most intensively surveyed areas of NW Europe. This has led to the production of archaeological distribution maps, which show a distinct pattern regarding the temporal and spatial distribution of these archaeological sites. Some areas with a presumed high ecological value, such as the large but shallow Late Glacial fossil lake of the Moevaart Depressie (ca. 15km long and 2,5km wide), seem to have been attractive settlement locations in Prehistory, given the high amount of close-lying sites along its borders and on the cover sand ridge on its northern border. Habitation however seems to have ‘moved' in time, and is completely absent in Protohistory and even the Roman Period. During the Late Glacial and Holocene the landscape in the Belgian area of Sandy Flanders was subjected to major changes due to climatic fluctuations, and besides human factors, environmental conditions such as topography, soil, vegetation, but also hydrology and climate, may have influenced settlement conditions throughout time and played a role in this change in site location and the occupational history of the region. In this light an inter-disciplinary project 'Prehistoric settlement and land-use systems in Sandy Flanders (NW Belgium): a diachronic and geoarchaeological approach' (GOA project, UGent), involving archaeology, geography, palaeoecology, sedimentology and geophysical survey, has been undertaken. The study of both "empty" and densely inhabited areas is ongoing and

    Full Text Available In the Walloon Region (Belgium, 239 sites have been selected to be included in the Natura 2000 network. The next step is to write designation acts in order to legally protect these 221,000 ha. In this pilot study, a designation act was elaborated for a Natura 2000 site of 2,569 ha and located in the Lesse-and-Lomme area within the Calestienne region. Although the site includes 40 ha of calcareous grasslands, characterised by an exceptional flora and fauna, this habitat is very threatened by abandonment and fragmentation.The methodology used to elaborate the designation act is presented with respect to calcareous grassland. Firstly, in spring and summer 2003, an accurate map of natural habitats was produced, with every single patch of calcareous grassland being mapped. Information was also collected in order to evaluate conservation status. Based on this information, conservation status was then assessed with respect to three different criteria: (1 integrity of the cortege species, (2 habitat structure and (3 degradations. Thirdly, the site was divided into objective zones according to the different habitats and species of Community interest found in the site. Hence, an objective zone was delineated for calcareous grasslands. This objective zone was then divided in several management units. Finally, at these different spatial levels (site, objective zone, management unit, management measures were suggested. As a result, in the draft designation act, the target is to maintain or restore 230 ha of calcareous grassland, instead of the existing 40 ha. This ambitious target requires large-scale restoration and an efficient grazing scheme. These will need important resources for their successful implementation

    M. Van Geet

    2009-02-01

    Full Text Available In order to protect man and the environment, long-lasting, passive solutions are needed for the different categories of radioactive waste. In Belgium, three main categories of conditioned radioactive waste (termed A, B and C are defined by radiological and thermal power criteria. It is expected that Category A waste – low and intermediate level short-lived waste – will be disposed in a near-surface facility, whereas Category B and C wastes – high-level and other long-lived radioactive waste – will be disposed in a deep geological repository. In both cases, the long-term safety of a given disposal facility is evaluated. Different scenarios and assessment cases are developed illustrating the range of possibilities for the evolution and performance of a disposal system without trying to predict its precise behaviour. Within these scenarios, the evolution of the climate will play a major role as the time scales of the evaluation and long term climate evolution overlap. In case of a near-surface facility (Category A waste, ONDRAF/NIRAS is considering the conclusions of the IPCC, demonstrating that a global warming is nearly unavoidable. The consequences of such a global warming and the longer term evolutions on the evolution of the near-surface facility are considered. In case of a geological repository, in which much longer time frames are considered, even larger uncertainties exist in the various climate models. Therefore, the robustness of the geological disposal system towards the possible results of a spectrum of potential climate changes and their time of occurrence will be evaluated. The results of climate modelling and knowledge of past climate changes will merely be used as guidance of the extremes of climate changes to be considered and their consequences.

    A core of 173 cm of ombrotrophic Misten peat bog from the Hautes-Fagnes Plateau in Eastern Belgium provides a record of Rare Earth Elements (REE) deposition allowing to trace dust fluxes in West Europe during the historical record (last 2500 years). REE and lithogenic element analyses, as well as the Nd isotopes, were performed by HR-ICP-MS and MC-ICP-MS, respectively in peat layers dated by 210Pb and 14C. The parallel variations of REE concentration with lithogenic conservative elements confirms that REE are immobile in the studied peat bog and can be used as tracers of dust deposition. Dust fluxes show pronounced increase at BC300, AD600, 1000AD, 1200AD and from 1700AD, recording either influence of human activities (regional erosion due to forest clearing and soil cultivation activities) or local and regional climate changes. Using Nd isotope allows to decipher between local and distal causes. The ENd variability (-13 to -9) is interpreted by a mixing between dust sources from local soils and desert particles. Three periods characterised by dominant-distal sources (at 320AD, 1000 AD and 1700AD) are consistent with local wetter intervals as indicated by lower humification degree. Local erosion prevails durier drier (higher humification) intervals (-100AD, 600AD). On a global scale more distal supplies are driven during colder periods, in particular Oort and Maunder minima. Combining geochemical elementary content and isotope data in ombrotrophic peat allows to decipher between dust flux changes related to human and climate forcing.

    Nitro-organic compounds were determined in a one-year set of atmospheric PM10 filter samples that were collected at a rural background site in Hamme, Belgium. In an earlier study, it was found that the site was substantially impacted by wood burning, making the filter samples appropriate for further investigations on wood burning indicators. In total, four groups of nitro-aromatic compounds (with molecular weights (MWs) of 139, 155, 169, and 183), α-pinene-related nitrooxy-organosulfates (MW 295), and the resin acid dehydroabietic acid (DHAA, MW 300) were quantified using liquid chromatography combined with negative ion electrospray ionization mass spectrometry. The annual mean concentrations were 0.94, 6.0, 7.7, 4.8, 7.8, and 1.76 ng m-3 for the sum of the nitrophenols (MW 139), 4-nitrocatechol (MW 155), the sums of the methyl-nitrocatechols (MW 169), of the dimethyl-nitrocatechols (MW 183), and of the α-pinene-related nitrooxy-organosulfates (MW 295), and DHAA (MW 300), respectively. 4-nitrocatechol, the sum of the methyl-nitrocatechols, and the sum of the dimethyl-nitrocatechols were substantially correlated with levoglucosan (r-values of 0.71, 0.66, and 0.65, respectively), consistent with their proposed origin from biomass burning. The nitro-aromatic compounds were also observed during the summer months, indicating a non-negligible usage of wood burning for domestic purposes at the site. The α-pinene-related nitrooxy-organosulfates (MW 295) were detected in high concentrations during the winter period, but they were poorly correlated with the biomass burning tracers. All of the targeted species showed a clear seasonal variation with highest concentrations in winter, followed by autumn, spring, and summer. Based on the DHAA measurements, it is suggested that burning of softwood is likely an important source for the formation of all the nitro-organic compounds measured.

    Full Text Available Introduction: Due to highly active antiretroviral therapy (HAART, HIV-1 infection has evolved from a lethal to a chronic disease. As such, health-related quality of life (HRQoL has become an important outcome variable. The purpose of this study was to identify socio-economic, behavioural, (neuropsychological and clinical determinants of HRQoL among people living with HIV (PLHIV. Methods: This study was conducted between 1 January and 31 December 2012 at the AIDS Reference Centre of Ghent University Hospital, a tertiary care referral centre in Belgium. Validated self-report questionnaires were administered to collect socio-demographic data, to assess HRQoL (Medical Outcomes Study-HIV, depressive symptoms (Beck Depression Inventory-II and adherence to HAART (Short Medication Adherence Questionnaire and to screen for neurocognitive dysfunction. Results: A total of 237 people participated, among whom 187 (78.9% were male. Mean age was 45.8±10.7 years and 144 (63.7%, 144/226 participants were homosexual. Median physical and mental health score (PHS, MHS were 55.6 (IQR 48.2–60.6 and 52.0 (IQR 44.2–57.9, respectively. Multivariable regression analysis revealed that incapacity to work, depressive symptoms, neurocognitive complaints (NCCs, dissatisfaction with the patient–physician relationship and non-adherence were all negatively associated with HRQoL. Conclusions: Socio-economic (work status, behavioural (adherence and (neuropsychological (depressive symptoms, NCCs determinants independently impact HRQoL among this cohort of PLHIV. Clinical parameters (viral load, CD4 cell count were not independently associated with HRQoL.

    Full Text Available To assess the coverage for cervical cancer screening as well as the use of cervical cytology, colposcopy and other diagnostic and therapeutic interventions on the uterine cervix in Belgium, using individual health insurance data.The Intermutualistic Agency compiled a database containing 14 million records from reimbursement claims for Pap smears, colposcopies, cervical biopsies and surgery, performed between 2002 and 2006. Cervical cancer screening coverage was defined as the proportion of women aged 25-64 that had a Pap smear within the last 3 years.Cervical cancer screening coverage was 61% at national level, for the target population of women between 25 and 64 years old, in the period 2004-2006. Differences between the 3 regions were small, but varied more substantially between provinces. Coverage was 70% for 25-34 year old women, 67% for those aged 35-39 years, and decreased to 44% in the age group of 60-64 years. The median screening interval was 13 months. The screening coverage varied substantially by social category: 40% and 64%, in women categorised as beneficiary or not-beneficiary of increased reimbursement from social insurance, respectively. In the 3-year period 2004-2006, 3.2 million screen tests were done in the target group consisting of 2.8 million women. However, only 1.7 million women got one or more smears and 1.1 million women had no smears, corresponding to an average of 1.88 smears per woman in three years of time. Colposcopy was excessively used (number of Pap smears over colposcopies = 3.2. The proportion of women with a history of conisation or hysterectomy, before the age of 65, was 7% and 19%, respectively.The screening coverage increased slightly from 59% in 2000 to 61% in 2006. The screening intensity remained at a high level, and the number of cytological examinations was theoretically sufficient to cover more than the whole target population.

    Full Text Available Abstract Background Most quality improvement programs in diabetes care incorporate aspects of clinician education, performance feedback, patient education, care management, and diabetes care teams to support primary care physicians. Few studies have applied all of these dimensions to address clinical inertia. Aim To evaluate interventions to improve adherence to evidence-based guidelines for diabetes and reduce clinical inertia in primary care physicians. Design Two-arm cluster randomized controlled trial. Participants Primary care physicians in Belgium. Interventions Primary care physicians will be randomly allocated to 'Usual' (UQIP or 'Advanced' (AQIP Quality Improvement Programs. Physicians in the UQIP will receive interventions addressing the main physician, patient, and office system factors that contribute to clinical inertia. Physicians in the AQIP will receive additional interventions that focus on sustainable behavior changes in patients and providers. Outcomes Primary endpoints are the proportions of patients within targets for three clinical outcomes: 1 glycosylated hemoglobin Primary and secondary analysis Statistical analyses will be performed using an intent-to-treat approach with a multilevel model. Linear and generalized linear mixed models will be used to account for the clustered nature of the data, i.e., patients clustered withinimary care physicians, and repeated assessments clustered within patients. To compare patient characteristics at baseline and between the intervention arms, the generalized estimating equations (GEE approach will be used, taking the clustered nature of the data within physicians into account. We will also use the GEE approach to test for differences in evolution of the primary and secondary endpoints for all patients, and for patients in the two interventions arms, accounting for within-patient clustering.

    Full Text Available Spirituality/religion serves important roles in coping, survival and maintaining overall wellbeing within African cultures and communities, especially when diagnosed with a chronic disease like HIV/AIDS that can have a profound effect on physical and mental health. However, spirituality/religion can be problematic to some patients and cause caregiving difficulties. The objective of this paper was to examine the role of spirituality/religion as a source of strength, resilience and wellbeing among sub-Saharan African (SSA migrant women with HIV/AIDS. A qualitative study of SSA migrant women was conducted between April 2013 and December 2014. Participants were recruited through purposive sampling and snowball techniques from AIDS Reference Centres and AIDS workshops in Belgium, if they were 18 years and older, French or English speaking, and diagnosed HIV positive more than 3 months beforehand. We conducted semi-structured interviews with patients and did observations during consultations and support groups attendances. Thematic analysis was used to analyse the data. 44 women were interviewed, of whom 42 were Christians and 2 Muslims. None reported religious/spiritual alienation, though at some point in time many had felt the need to question their relationship with God by asking "why me?" A majority reported being more spiritual/religious since being diagnosed HIV positive. Participants believed that prayer, meditation, regular church services and religious activities were the main spiritual/religious resources for achieving connectedness with God. They strongly believed in the power of God in their HIV/AIDS treatment and wellbeing. Spiritual/religious resources including prayer, meditation, church services, religious activities and believing in the power of God helped them cope with HIV/AIDS. These findings highlight the importance of spirituality in physical and mental health and wellbeing among SSA women with HIV/AIDS that should be taken into

    The concentrations of 16 US-EPA criteria polycyclic aromatic hydrocarbons (PAHs) were monitored during various seasons at six different cities/locations in the northern part of Belgium. Pressurized liquid extraction (PLE) was used for the fast recovery of PAHs from quartz fibre filters (QFFs) and polyurethane foams (PUFs) in less than 30 min with minimum solvent consumption prior to their analysis with high-performance liquid chromatography. The concentrations of PAHs varied significantly at the studied sites and showed relation to different anthropogenic activities, such as vehicular emission (diesel/gasoline), incinerator, petroleum/oil burning, coke production, and wood/coal combustion. The annual average PAH concentration ranged from 17 (at a rural site) to 114 ng m -3 (near a petroleum harbour and industry). Most of the human carcinogenic PAHs were found to be associated with suspended particulate matter, which forms around ˜55% of the total PAH levels in aerosols. Relatively higher concentrations of PAHs were detected in aerosol samples during winter compared with other seasons, whereas no clear seasonal trend was observed for the vapour phase PAHs. This fraction is likely to be more local in origin; hence, it can be used as a site-specific characteristic. The site-specific concentrations of individual PAHs were also used in diagnostic ratio evaluations and in principal component analysis to find their relation with various anthropogenic activities. These results show that the vehicular emission is a major source of PAHs in Flanders, although other anthropogenic sources, as above, have also an impact on the total PAH levels.

    Full Text Available Abstract Background Since most patients prefer out-of-hospital death, place of death can be considered an indicator of end-of-life care quality. The study of trends in place of death is necessary to examine causes of shifts, to evaluate efforts to alter place of death and develop future policies. This study aims to examine past trends and future projections of place of death. Methods Analysis of death certificates (decedents aged ≥ 1 year in Belgium (Flanders and Brussels Capital region 1998-2007. Trends in place of death were adjusted for cause of death, sociodemographic characteristics, environmental factors, numbers of hospital beds, and residential and skilled nursing beds in care homes. Future trends were based on age- and sex-specific mortality prognoses. Results Hospital deaths decreased from 55.1% to 51.7% and care home deaths rose from 18.3% to 22.6%. The percentage of home deaths remained stable. The odds of dying in a care home versus hospital increased steadily and was 1.65 (95%CI:1.53-1.78 in 2007 compared to 1998. This increase could be attributed to the replacement of residential beds by skilled nursing beds. Continuation of these trends would result in the more than doubling of deaths in care homes and a decrease in deaths at home and in hospital by 2040. Conclusions Additional end-of-life care resources in care homes largely explain the decrease in hospital deaths. Care homes will become the main locus of end-of-life care in the future. Governments should provide sufficient skilled nursing resources in care homes to fulfil the end-of-life care preferences and needs of patients.

  9. Water-levels fluctuations in a borehole at the Royal Observatory of Belgium: Effects on local gravity, Earth tidal, and barometric responses

    Delcourt-Honorez, M.

    A borehole was drilled at the Royal Observatory of Belgium in Brussels, next to the superconducting gravimeter. Three aquifers belong to the 'multiple aquifer-aquitard system'. Continuously since Jun. 1984, various kinds of water levels variations are registered: long term and short term variations and, in the intermediate and deep wells, periodic tidal oscillations. Moreover, the water table and the pressure heads respond to the atmospheric pressure variations. The water levels variations perturbing effects in the superconducting gravimeter registrations are estimated and the hydraulic problem and the consolidation problem are studied. The classical Bouguer's formula in theories is enlarged, taking into account the nature of the layers, the expansions or compressions of each layer, the global land surface displacement and the various hydrostatic occurrences of phases on porous media. The Bouguer's theory is also extended to the case of a finite thickness layer, by a numerical integration. The water levels variations in the intermediate and deep aquifers (at long term, at short term, and the barometric and tidal responses) are only inducing negligible perturbing effects on the superconducting gravimeter registrations but the effect of the water table drift is at the limit of the actual precision of the gravimeter registrations. On the other hand, the barometric and tidal responses of the well-aquifer systems are used to estimate the in situ parameters of both the aquifers and the aquifer system (porosity, specific storage, vertical compressibility, and permeability). The estimated values are in good agreement with those deduced by using hydrogeological, soil, and rock mechanics considerations. The research presented can be applied to any hydrogeological configuration with any complexity.

    This document provides data and operations needed to evaluate the impacts of the nuclear phaseout on the respect of the Kyoto protocol. The data are based on the belgium electricity production. The author concludes that the nuclear power plants shutdown will lead to a non respect of the kyoto protocol in unacceptable limits. To respect the protocol, he presents two possibilities: the today nuclear park and the use of 1600 wind turbines of 2 MW, or the improvement of the energy efficiency of the thermal power plants.

    The annual NO2 concentrations in many European cities exceed the established air quality standard. This situation is mainly caused by Diesel cars whose NOx emissions are higher on the road than during type approval in the laboratory. Moreover, the fraction of NO2 in the NOx emissions of modern diesel cars appears to have increased as compared to previous models. In this paper, we assess 1) to which level the distance-specific NOx emissions of Diesel cars should be reduced to meet established air quality standards and 2) if it would be useful to introduce a complementary NO2 emissions limit. We develop a NO2 pollution model that accounts in an analysis of 9 emission scenarios for changes in both, the urban background NO2 concentrations and the local NO2 emissions at street level. We apply this model to the city of Antwerp, Belgium. The results suggest that a reduction in NOx emissions decreases the regional and urban NO2 background concentration; high NO2 fractions increase the ambient NO2 concentrations only in close spatial proximity to the emission source. In a busy access road to the city centre, the average NO2 concentration can be reduced by 23% if Diesel cars emitted 0.35 g NOx/km instead of the current 0.62 g NOx/km. Reductions of 45% are possible if the NOX emissions of Diesel cars decreased to the level of gasoline cars (0.03 g NOx/km). Our findings suggest that the Real-Driving Emissions (RDE) test procedure can solve the problem of NO2 exceedances in cities if it reduced the on-road NOx emissions of diesel cars to the permissible limit of 0.08 g/km. The implementation of a complementary NO2 emissions limit may then become superfluous. If Diesel cars continue to exceed by several factors their NOx emissions limit on the road, a shift of the vehicle fleet to gasoline cars may be necessary to solve persisting air quality problems.

Au total 50 interviews, sur base de la technique laddering, concernant la consommation de la viande ont été effectuées auprès de la première et deuxième génération de musulmans en Belgique. Les résultats sont repris dans une carte de valeurs hiérarchiques (HVM représentant une carte de structures cognitives agrégées. De manière générale, les consommateurs musulmans achètent de la viande pour atteindre les valeurs suivantes : la santé, la foi, le respect pour le bien-être des animaux mais également pour jouir de la vie et prendre soin de la famille.

    Full Text Available Measurements of organic marker compounds and inorganic species were performed on PM2.5 aerosols from a Belgian forest site that is severely impacted by urban pollution ("De Inslag", Brasschaat, Belgium during a 2007 summer period within the framework of the "Formation mechanisms, marker compounds, and source apportionment for biogenic atmospheric aerosols (BIOSOL" project. The measured organic species included (i low-molecular weight (MW dicarboxylic acids (LMW DCAs, (ii methanesulfonate (MSA, (iii terpenoic acids originating from the oxidation of α-pinene, β-pinene, d-limonene and Δ3-carene, and (iv organosulfates related to secondary organic aerosol from the oxidation of isoprene and α-pinene. The organic tracers explained, on average, 5.3 % of the organic carbon (OC, of which 0.7 % was due to MSA, 3.4 % to LMW DCAs, 0.6 % to organosulfates, and 0.6 % to terpenoic acids. The highest atmospheric concentrations of most species were observed during the first five days of the campaign, which were characterised by maximum day-time temperatures >22 °C. Most of the terpenoic acids and the organosulfates peaked during day-time, consistent with their local photochemical origin. High concentrations of 3-methyl-1,2,3-butanetricarboxylic acid (MBTCA and low concentrations of cis-pinonic acid were noted during the first five days of the campaign, indicative of an aged biogenic aerosol. Several correlations between organic species were very high (r>0.85, high (0.7<r<0.85, or substantial (0.5<r<0.7, suggesting that they are generated through similar formation pathways. Substantial correlations with temperature were found for OC, water-soluble OC, MBTCA, and several other organic species. MBTCA and terebic acid were highly correlated with the temperature (r>0.7 and showed an Arrhenius-type relationship, consistent with their formation through OH radical chemistry.

  14. Quantification of human impact on past erosion and sediment dynamics - lessons learned from a case study in the Dijle catchment, Belgium

    Humans have changed the intensities and processes of soil erosion, sediment transport and sediment deposition since the introduction of agriculture. Although the general framework of these changes are well established, we still lack a detailed model of the impact-response relationship to fully grasp how, when and to what extent humans have changed the sediment transfers at the catchment scale. In this study we provide an holistic approach that combines detailed and well-dated data on erosion intensities and floodplain sedimentation with detailed data on human impact in the landscape, for the Dijle catchment (758 km²), Belgium. The field data shows increasing erosion and sedimentation rates throughout the Holocene resulting in important changes in floodplain morphology. These changes, however, are not occurring synchronous: large variability in the timing of the system response has been observed both at the scale of individual floodplain transects as well as at the catchment scale. Moreover, a detailed time-differentiated sediment budget, together with pollen-based quantitative measures of human impact , reveals important differences in time-lags, threshold levels and in the impact-response model at the catchment scale. We attribute this to the spatial and temporal variability in hillslope-floodplain connectivity and to differences in the timing and intensity of human activities between subcatchments. Overall, our data shows that the relationship between the intensity of anthropogenic disturbances and the changes in sediment dynamics is non-linear, both in space and time, and indicates that traditional extrapolation techniques and assumptions in erosion-sedimentation studies can be questioned. In particular, the use of point-specific volumetric sedimentation rates is problematic for obtaining a correct understanding of the human impact on sediment transfers. It also means that regional or global sediment databases needs to be sufficient large to correctly interpret

    Speleothems are now regarded as valuable archives of climatic conditions on the continents, offering the advantages of absolute U-series dating relative to other continental climate proxy recorders such as lake sediments and peat cores. High spatial resolution measurements of Mg, U, Sr, Ba and Zn were realized by laser-ablation inductively coupled plasma mass spectrometry in the Belgian Père Noël cave Holocene stalagmite (Verheyden et al., 2000, 2008). The stalagmite of 65 cm long was deposited from ~12000 years to ~2000 years dated by U/Th method. Mg, Sr, Ba, U, and Zn are known as indicators for hydrological conditions (e.g. Ayalon et al., 1999; Fairchild et al., 2000). Mg, Sr, Ba concentrations are positively correlated (r> 0.7) with similar changes in the δ 13C implying similar processes influence their concentration changes. U has an inverse relationship with δ 13C. The study suggests that trace elements in the Père Noël stalagmite have the potential to provide high resolution insights into variability in water recharge during the Holocene.

    In an evolving energy system it is important that urbanized areas contribute to their own energy demands. To reduce greenhouse gas emissions sustainable energy systems with a high efficiency are required, e.g. using urban aquifers as an ecosystem service. Here the potential of seasonal aquifer thermal energy storage and recovery (ATES) for the Brussels-Capital Region, Belgium is investigated. An important shallow geologic formation in the Brussels Capital Region is the Brussels Sand formation, a 20-60 m thick phreatic aquifer. The Brussels Sand Formation is known for its potential for ATES systems, but also for its varying redox and hydraulic conditions. Important limiting factors for ATES systems in the Brussels Sand Formation therefore are the hydraulic conductivity and the geochemical composition of the groundwater. Near the redox boundary iron hydroxide precipitation can negatively influence ATES well performance due to clogging. The interactions between physical processes (e.g. particle transport and clogging in the wider proximity of the ATES well) and chemical processes (e.g. influence of the operation temperatures on precipitation processes) during ATES operation are complex but not well understood. Therefore we constructed numerical groundwater flow models in MODFLOW to estimate maximum pumping and injection rates of different hydraulic conditions and competing water uses in the Brussels Sand Formation. In further steps the thermal potential for ATES was quantified using MT3DMS and the reactive transport model PHT3D was applied to assess the effects of operating ATES systems near the redox boundary. Results show that initial mixing plays an important role in the development of iron(hydr)oxide precipitation around the ATES wells, with the highest concentrations around the cold wells. This behavior is enhanced by the temperature effect; temperature differences of ΔT≈10°C already influence the iron (hydr)oxide concentration. The initial injection into the

    Although widely used to measure CO2 and other gas fluxes, the eddy covariance technique still needs methodological improvements. This research focuses on the high frequency loss corrections, which are especially important when using a closed-path infrared gas analyzer. We compared three approaches to implement these corrections for CO2 fluxes and evaluated their impact on the carbon balance at the Dorinne Terrestrial Observatory (DTO), an intensively grazed grassland site in Belgium. The carbon balance at DTO is also the object of a separate analysis (Gourlez de la Motte et al., Geophysical Research Abstract, Vol. 18, EGU2016-6813-1, 2016). In the first approach, the computation of correction factors was based on the measured sensible heat cospectra ('local' cospectra), whereas the other two were based on theoretical models (Kaimal et al., 1972). The correction approaches were validated by comparing the nighttime eddy covariance CO2 fluxes corrected with each approach and in situ soil respiration measurements. We found that the local cospectra differed from the Kaimal theoretical shape, although the site could not be considered 'difficult' (i.e., fairly flat, homogeneous, low vegetation, sufficient measurement height), appearing less peaked in the inertial subrange. This difference greatly affected the correction factor, especially for night fluxes. Night fluxes measured by eddy covariance were found to be in good agreement with in situ soil respiration measurements when corrected with local cospectra and to be overestimated when corrected with Kaimal cospectra. As the difference between correction factors was larger in stable than unstable conditions, this acts as a selective systematic error and has an important impact on annual fluxes. On the basis of a 4-year average, at DTO, the errors reach 71-150 g C m-2 y-1 for net ecosystem exchange (NEE), 280-562 g C m-2 y-1 for total ecosystem respiration (TER) and 209-412 g C m-2 y-1 for gross primary productivity (GPP

The GUINEVERE project is carried out in the context of domain 2 of IP-EUROTRANS, ECATS, devoted to specific experiments for the coupling of an accelerator, a target and a subcritical core. These experiments should provide an answer to the questions of on-line reactivity monitoring, subcriticality determination and operational procedures (loading, startup, shutdown) in an ADS by 2009–2010. The GUINEVERE project will make use of the VENUS reactor, serving as a lead fast critical facility, coupled to a continuous beam accelerator. In order to achieve this goal, the VENUS facility has to be adapted and a modified GENEPI-C accelerator has to be designed and constructed. During the years 2007 and 2008, the VENUS facility will be modified in order to allow the experimental programme to start in 2009

    Mosquito (Diptera: Culicidae) distribution data from a recent inventory of native and invading mosquito species in Belgium were compared with historical data from the period 1900-1960 that were retrieved from a revision of the Belgian Culicidae collection at the Royal Belgian Institute of Natural Sciences. Both data sets were used to investigate trends in mosquito species richness in several regions in Belgium. The relative change in distribution area of mosquito species was particularly important for species that use waste waters and used tires as larval habitats and species that recently shifted their larval habitat to artificial larval habitats. More importantly, several of these species are known as vectors of arboviruses and Plasmodium sp. and the apparent habitat shift of some of them brought these species in proximity to humans. Similar studies comparing current mosquito richness with former distribution data retrieved from voucher specimens from collections is therefore encouraged because they can generate important information concerning health risk assessment at both regional and national scale.

    In the last decade, biochar has been increasingly investigated as a soil amendment for long-term soil carbon sequestration while improving soil fertility. On the short term, biochar application to soil generally increases soil respiration as well as microbial biomass and activity and affects significantly the microbial community structure. However, such effects are relatively short-term and tend to vanish over time. In our study, we investigated the long-term impact of charcoal accumulation and land-use on soil biota in temperate haplic Luvisols developed in the loess belt of Wallonia (Belgium). Charcoal-enriched soils were collected in the topsoil of pre-industrial (>150 years old) charcoal kilns in forest (4 sites) and cropland (5 sites). The topsoil of the adjacent charcoal-unaffected soils was sampled in a comparable way. Soils were characterized (pH, total, organic and inorganic C, total N, exchangeable Ca, Mg, K, Na, cation exchange capacity and available P) and natural soil organic matter (SOM) and black carbon (BC) contents were determined by differential scanning calorimetry. After rewetting at pF 2.5, soils were incubated during 140 days at 20 °C. At 70 days of incubation, 10 g of each soil were freeze dried in order to measure total microbial biomass and community structure by PLFA analysis. The PLFA dataset was analyzed by principal component analysis (PCA) while soil parameters were used as supplementary variables. For both agricultural and forest soils, the respiration rate is highly related to the total microbial biomass (R²=0.90). Both soil respiration and microbial biomass greatly depend on the SOM content, which indicates that the BC pool is relatively inert microbiologically. Land-use explains most of the variance in the PLFA dataset, largely governing the first principal component of the ACP. In forest soils, we observe a larger proportion of gram + bacteria, actinomycetes and an increased bacteria:fungi ratio compared to cropland, where gram

    Full Text Available Measurements of organic marker compounds and inorganic species were performed on PM2.5 aerosols from a Belgian forest site that is severely impacted by urban pollution ("De Inslag", Brasschaat, Belgium during a 2007 summer period within the framework of the "Formation mechanisms, marker compounds, and source apportionment for biogenic atmospheric aerosols (BIOSOL" project. The objectives of this study were to determine sources, source processes, time series, and diel variations of the organic species, and to explore the relationships between their concentrations and those of trace gases (O3, NO2, SO2, and CO2 or meteorological parameters (temperature, relative humidity, wind speed, and rain fall. The measured organic species included (i low-molecular weight (MW dicarboxylic acids (LMW DCAs, (ii methanesulfonate (MSA, and (iii terpenoic acids originating from the oxidation of α-pinene, β-pinene, d-limonene and Δ3-carene, and (iv organosulfates related to secondary organic aerosol (SOA from the oxidation of isoprene and α-pinene. The measurements of MSA, the LMW DCAs and selected inorganic species were done with ion chromatography (IC, while those of the terpenoic acids and organosulfates were performed using liquid chromatography with negative ion electrospray ionisation mass spectrometry [LC/(−ESI-MS]. The organic tracers explained, on average, 5.3 % of the organic carbon (OC, of which 0.7 % was due to MSA, 3.4 % to LMW DCAs, and 1.2 % to organosulfates and terpenoic acids. The highest atmospheric concentrations of most species were observed during the first five days of the campaign, which were characterised by maximum day-time temperatures >22 °C. Most of the terpenoic acids and the organosulfates peaked during day-time, consistent with their photochemical origin, except the MW 295 α-pinene-related nitrooxy organosulfates and the terpenoic acids,

    An increasing demand for food, feed and bioenergy, and simultaneously a decline of arable land will require an intensive agricultural production including the use of pesticides. With an increasing use of pesticides the occurrence of an accelerated degradation potential has to be assessed. Atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] is one of the most widely used herbicides in the world. Even though its use was banned in several countries it is still widely used throughout America and the Asia-Pacific region. Atrazine is the most widely used herbicide in maize plantations in Brazil and the US. The use of atrazine in Belgium and all EU member states was banned in September 2004, with the permission to consume existing stocks until October 2005. Atrazine and its residues are still regularly detected in soil, ground and surface waters even years after its prohibition. Its persistence in soil and in association with organic particles might become crucial in terms of erosion due to climate and environmental changes. Due to its potential microbiological accessibility, the microbial mineralization of atrazine competes with chemical/physical interaction such as sorption and binding processes of the chemical molecule in the soil matrix. Binding or intrusion of the chemical on soil components results in a decrease of its accessibility for soil microbes, which does not necessarily exclude the molecule from environmental interactions. In the present study the accelerated atrazine degradation in agriculturally used soils was examined. Soil samples were collected from a Rhodic Ferralsol, Campinas do Sul, South Brazil, and Geric Ferralsol, Correntina, Northeastern Brazil. The sampling site of the Rhodic Ferralsol soil has been under crop rotation (soybean/wheat/maize/oat) since 1990. The Geric Ferralsol site has alternately been cultivated with maize and soybean since 2000. Both areas have been treated biennially with atrazine at recommended doses of 1.5 - 3

    version of the model developed for natural vegetation has been upgraded to include crop systems and pastures. The ABM (Murray-Rust, Journal of Land Use Science, 6(2-3):83-99, 2011) describes the management choices (e.g., crop rotation, intensive agriculture or organic farming, etc) for each land plot, as well as the possible change in their affectation (e.g., conversion of farm fields to residential areas in response to urbanization), under different socio-economic contexts described in the storyline of three scenarios depicting general societal orientations (business-as-usual; market oriented; sustainability oriented). As a result, the ABM produces a dynamic evolution of land use and management options to be passed on to the DVM for further analysis. The outputs from the DVM allow evaluating quantitatively the provision of EGS by each land plot. This DVM-ABM modelling tool is thus able to describe the future evolution of land use and land cover, as well as of EGS production, in the context of socio-economic scenarios. The model is applied to a case study area covering four municipalities located in central Belgium close to Brussels and Leuven. The area is mostly composed of agricultural fields (crops and meadows), residential areas and a large protected forest (Meerdaalbos) and is subject to intense urbanization pressure due to the proximity to Brussels.

    Recently, two conglomerate levels were discovered in the latest Ordovician Génicot Formation in the Puagne area, western Condroz Inlier, Belgium (Herbosch et al. 2001; in press). In the middle of the latter formation, a lower matrix-supported conglomerate approximately 1.2 m thick and with an erosional base is separated by 5.5 m of mudstone and siltstone from a second pebble-supported conglomerate of 2.05 m thick. A local chitinozoan biozonation places both conglomerates in the late Ashgill (stage 6). The sediments of the unit are supposed to be deposited on a moderately deep shelf. However, the sudden presence of the two conglomerates, the lower one with an erosional base, is interpreted as the sedimentological response to the sea level drop associated with the Hirnantian glaciation and deglaciation event (Vanmeirhaeghe &Verniers, submitted). This poster presents the results of a comparison of the chitinozoan biozonation of the Puagne area with that of the Ashgill type area in the Howgill Fells inliers, northern England, U.K. This resulted in a more accurate dating of the two conglomerates and of the complete Génicot and the underlying Fosses Formations in Belgium.

    Full Text Available Abstract Background The increase in the number of people with dementia will lead to greater demand for residential care. Currently, large nursing homes are trying to transform their traditional care for residents with dementia to a more home-like approach, by developing small-scale living facilities. It is often assumed that small-scale living will improve the quality of life of residents with dementia. However, little scientific evidence is currently available to test this. The following research question is addressed in this study: Which (combination of changes in elements affects (different dimensions of the quality of life of elderly residents with dementia in long-term care settings over the course of one year? Methods/design A longitudinal comparative study in traditional and small-scale long-term care settings, which follows a quasi-experimental design, will be carried out in Belgium and the Netherlands. To answer the research question, a model has been developed which incorporates relevant elements influencing quality of life in long-term care settings. Validated instruments will be used to evaluate the role of these elements, divided into environmental characteristics (country, type of ward, group size and nursing staff; basic personal characteristics (age, sex, cognitive decline, weight and activities of daily living; behavioural characteristics (behavioural problems and depression; behavioural interventions (use of restraints and use of psychotropic medication; and social interaction (social engagement and visiting frequency of relatives. The main outcome measure for residents in the model is quality of life. Data are collected at baseline, after six and twelve months, from residents living in either small-scale or traditional care settings. Discussion The results of this study will provide an insight into the determinants of quality of life for people with dementia living in traditional and small-scale long-term care settings in

  11. Characterization of the porosity in Boom (Mol site, Belgium) and Opalinus (Mont Terri, Switzerland) clays - about the benefit of using ion beam milling tools and CRYO-SEM

    International Nuclear Information System (INIS)

    imaging of pore space at high resolution. The first of them is to use ion beam milling tools able to prepare smooth, damage free cross-sectioned surfaces. Two main ion source are available: (1) a broad ion beam (BIB, up to 3.5 mA) is suitable to produce large polished cross-sections area of few mm2, while the focused ion beam (FIB, 1 pA - 45 nA) is better used for fine and precise polished cross-sections area of about few μm2. The second alternative is to preserve the in-situ nanostructures of wet clay-stones by using cryogenic techniques in order to stabilize in-situ fluids at temperature of liquid nitrogen. A FIB/BIB-cryo- SEM instrument combines cryo-techniques to preserve wet samples, in-situ sample preparation by ion beam cross-sectioning (BIB or FIB) and observations of the stabilized microstructure at high resolution (SEM). Since the ion beam is directly embedded into the SEM, this instrument offers a unique way to get a direct access of the pore space in 3D by using a 'slice and view' procedure equivalent to nano-serial sectioning. This procedure allows us investigating the natural in-situ pore space as a 3D matrix. This contribution reports on a study of Boom and Opalinus clays from reference sites for research (respectively at Mol site, Belgium and Mont Terri, Switzerland) using cryo-SEM at cryogenic temperature, with ion beam cross-sectioning to prepare smooth, damage free surfaces. Pores commonly have crack-like tips, preferred orientation parallel to bedding and power law size distribution. We define a number of pore types depending on shape and location in the microstructure. 3-D reconstruction by serial cross-sectioning shows 3-D connectivity of the pore space and provide natural pore matrix for simulation of permeability using Lattice Boltzmann method. These findings offer a new insight into the morphology of pores and quantification of porosity down to nano-scale and provide the basis for microstructure-based models of transport in clays

    This study probes into the evolution in young-adult mortality according to urbanisation degree in Belgium and moves beyond mere description through decomposing mortality trends into changes in educational distribution and in overall mortality. As most of young-adult deaths are preventable and an enormous cost and loss to society, this study addresses a highly relevant public-health topic. Individual record-linked data between the Belgian censuses of 1991 and 2001 and register data on death and emigrations are used. Age-standardized mortality rates (ASMR), directly standardized to the European Population of 2013 are calculated with 95% confidence intervals (CI), as well as a decomposition measure to pinpoint the proportion mortality change attributable to differences in educational composition over time. The young-adult population consists of 2,458,637 19-34 year-olds in 1991, with 11,898 deaths in a five-year period, and is slightly smaller in 2001 with 2,174,368 young adults and 8138 deaths. Overall, there is a positive evolution towards lower young-adult mortality, with the strongest declines in men living in large urban areas (ASMR from 149.0 [CI 142.1-155.8] in 1991-1996 to 94.6 [88.9-100.3] in 2001-2006). Decomposition analysis shows that the decrease in male mortality in non-urban areas over time is largely due to changes in the educational composition, while mortality in urban areas mainly decreases because of a decline in overall mortality. In urban areas all educational groups have benefitted over time. This clearly demonstrates that living and growing up in an urban area does not always have to imply a health penalty, but can have health advantages as well.

    The Boom Clay formation (Oligocene) is studied as a reference host rock for methodological studies on deep geological disposal of radioactive waste. During excavation of galleries within the Clay formation (HADES underground research facility, Mol, Belgium), the physico-chemical conditions are significantly modified as an air–clay interface is created. In order to study the long-term impact of the air–clay contact on the organic matter contained in the Boom Clay, two types of samples were studied: (1) a reference series of clay samples having been in contact with the atmosphere of the HADES gallery for increasing times up to several years and (2) unaltered clay samples submitted to artificial oxidation in a ventilated oven at 80 °C. The evolution of geochemical data of the two series was compared using Rock-Eval pyrolysis, GC–MS and size exclusion chromatography. The organic matter of the unaltered clays sampled in the HADES galleries is dominated by type III kerogen (terrestrial) with some contribution of type II (marine) and is thermally immature. The evolution of geochemical parameters during air alteration for the two series are very similar. They show progressive oxidation of kerogen accompanied by the release of bitumen enriched in low molecular weight constituents. Molecular analysis evidences the presence of a complex mixture of aliphatic and aromatic O-bearing compounds, inherited from the degradation of kerogen as well as from the clay catalyzed oxidation of the bitumen. These results show that (1) air oxidation is a major process in the in situ alteration of the organic matter of Boom Clay within the HADES galleries, (2) laboratory oxidation experiments at 80 °C yield similar results as in situ air alteration of Boom Clay and (3) artificial air oxidation may be used to assess the long term exposure of the organic matter to air.

    The stalagmitic body of the 'Galerie des Vervietois' ('Grotte de Han', Belgium) has been sampled by numerous drillings. We present here two series studied by lithostratigraphy, palynology and absolute dating by the uranium series disequilibrium. These series allow one to date and reconstitute the palaeoclimatic sequence from isotopic substage 5.5 to isotopic substage 5.3, emphasizing the climatic deterioration of the isotopic substage 5.4 (Melisey I in the 'Grande Pile' sequence).

    Speleothems provide paleoclimate information on multi-millennial to decadal scales in the Holocene. However seasonal or even monthly resolved records remain scarce. They require fast growing stalagmites and a good understanding of the proxy transfer function on very short time scales. The Proserpine stalagmite from the Han-sur-Less cave (Belgium) displays seasonal layers of 0.5 to 2 mm thickness that reconstruct paleoclimates at a monthly scale. Through a regular cave monitoring, we acquired a good understanding of how δ18O and δ13C signals in modern calcite reflect climate variations on sub-seasonal scale. Cave parameters vary seasonally in response to the activity of the vegetation cover and outside air temperature. From December to June, the cave remains in "winter-mode". Outside temperatures are cold inducing low cave air and water temperatures. Bio-productivity in the soil is limited leading to low pCO2, higher δ13C composition of the CO2 in the cave air and high discharge due to the inactivity of the plant coverage. From June to December, the cave switches to "summer-mode" and the measured factors display an opposite behavior. The δ18O and δ13C signals of fresh calcite precipitated on glass slabs vary seasonally. Lowest δ18O values occur during the summer-mode when the δ13C values are high. The δ18O composition of the calcite is in equilibrium with the drip water δ18O and display seasonal variations due to changes in the cave air and water temperature. In contrast to the δ18O signal, δ13C values of the calcite precipitated on the glass slabs do not reflect equilibrium conditions. Highest δ13C values occur during summer, when discharge rates are low increasing the evaporation effect on the thin water film covering the stalagmite. This same antithetical behavior of the δ18O vs. the δ13C signals is seen in the monthly resolved speleothem record that covers the period between 1976 and 1985 AD. Dark layers are formed during summer, while light layers
