This article has two aims. Firstly, to introduce the important environmental inequality scholarship, mostly imported from the USA, in the Belgian context, where few studies have been carried out to date on this topic. Secondly, to propose an unconventional approach to environmental inequality scholarship by focusing on housing conditions as substantial environmental inequalities. On this latter premise, we based this study on the CEHD housing quality survey carried out in 2012 and 2013 in Wallonia, to test several hypotheses as regards the relationships between housing quality, poverty, and spatial differentiation – discrepancies among population and space. The results confirm most of our research hypotheses, showing important inequalities in terms of housing conditions between wealthy and poor populations, as well as between urban areas, on the one hand, and suburban and rural areas, on the other. Our findings call for new avenues and priorities for housing policies in Wallonia, and for further research on housing quality as environmental inequality: with a focus on a specific target public – single households, and on subjective perception of environmental nuisances in and surrounding home.

Background: The concept of a ‘specialist nurse’ has existed for many years and related education programmes are proliferating. However, while literature clearly outlines the roles and practice of registered nurses and advanced practice nurses, those of specialist nurses remain unclear and nursing specializations across Europe need clarifying. Aim: This pilot study aimed to explore the competencies, education requirements and regulation of specialist nurses in Europe. Design: A descriptive cross-sectional survey. Methods: An online questionnaire named ‘Specialist nurse and specialization in Europe’ was sent to 550 members of the European Federation of Nurse Educators and ten members of the European Specialist Nurses Organizations. Snowball sampling was then used to build a convenience sample of nurse educators, clinical nurses and specialist nurses, national nursing association members, and chief nursing officers from all European countries. Besides quantitative aspects, responses to open-ended questions were analysed using a qualitative content analysis process. Results: A total of 77 experts from 29 European countries responded to the questionnaire. Findings highlighted variations in titles, levels and length of education, certification, regulation and scope of practice for specialized nurses in Europe. Analysis of the promoted competencies revealed dominant clinical and technical aspects of the role with a high level of knowledge.Conclusions: The study emphasized the need to improve standards for education, certification and regulation for specialist nurses. Interpretation of the role and competencies is diverse with a weak presence of health policy that would enhance and develop the specialities. Implications for nursing and health policy: To address the current lack of provisions for automatic recognition of specialist nurses, common training frameworks corresponding to the relevant level of the European Qualifications Framework should promote lifelong learning and mobility, and enhance levels of health care and patient safety.

We introduce a new method for forecasting major El Niño/ La Niña events based on a wavelet mode decomposition. This methodology allows us to approximate the ENSO time series with a superposition of three periodic signals corresponding to periods of about 31, 43 and 61 months respectively with time-varying amplitudes. This pseudo-periodic approximation is then extrapolated to give forecasts. While this last one only resolves the large variations in the ENSO time series, three years hindcast as retroactive prediction allows to recover most of the El Niño/ La Niña events of the last 60 years.

We combine imaging of the proton aurora from the SI12-IMAGE instrument with ionospheric convection measurement from the SuperDARN radar network to analyze the cycle of magnetic flux opening and closure of the Earth magnetosphere. Interaction between the solar wind and the Earth geomagnetic environment causes a reconfiguration of the magnetic field that connects the interplanetary magnetic field (IMF) to the geomagnetic field. This reconnection process produces open magnetic field lines (i.e. field lines of the magnetosphere that close through the interplanetary medium) that are dragged to the magnetotail by the solar wind flow, where they eventually reconnect again, back to a closed topology. The SI12 imaging of the Doppler-shifted Lyman-α emission of the proton aurora is used to estimate the location of the boundary separating open and closed field lines at ionospheric altitude. We then estimate the open magnetic flux of the Earth magnetosphere, encircled by this boundary. The rate of reconnection causing a variation of the open magnetic flux can be expressed as a voltage in application of Faraday’s law. This voltage is measured along the open/closed field line boundary determined from the imaging data. The electric field associated with the voltage has two origins: motion of the boundary and the ionospheric field. We use the ionospheric electric field deduced from ionospheric convection measurement from the SuperDARN to estimate the reconnection voltage at the magnetopause (flux opening) and in the magnetotail (flux closure) accounting for the motion of the open/closed field line boundary determined from the SI12 images. The method is applied during several (strong) geomagnetic storms. These intervals are characterized by large values of open flux and reconnection rates, as a result of coupling between the solar wind and the geomagnetic environment. We present these results in terms of a magnetospheric mode that develops under strong coupling with the solar wind, a condition known to be prone to the development of sawtooth events, characterized by overloading of the magnetosphere with open magnetic flux.

Les termites des régions tropicales sont d’une importance critique pour le fonctionnement et les services écosystémiques dans les régions de forêt claire et de savane. Les termitières peuvent également être utilisées comme engrais et bio-indicateurs de perturbations anthropiques telles que l’agriculture ou la production de charbon. La télédétection peut contribuer à identifier et caractériser la densité et la distribution des termitières à moindres frais. Afin de tester son efficacité, les termitières ont été identifiées sur le terrain et comparées avec les résultats d’interprétation de photographies aériennes Google Earth en libre accès. Cette comparaison a été appliquée sur 17 sites dans l’hinterland de la ville minière de Lubumbashi, Katanga, République Démocratique du Congo, confrontée à une croissance élevée de population, à l’insécurité alimentaire ainsi que d’intenses fragmentation et dégradation de la couverture originelle de forêt claire (Miombo). Les influences de la hauteur et du diamètre des termitières ainsi que de la période d’acquisition de l’image (année et saison) ont été testées statistiquement. Le nombre de termitières observées sur le terrain est généralement surestimé sur l’image. La hauteur et la saison des pluies en favorisent l’identification correcte, tandis que la distribution spatiale n’est pas significativement influencée par les erreurs d’identification. Un modèle correctif a été défini et sa pertinence statistiquement vérifiée. L’identification des termitières via Google Earth s’avère efficace tant que la position précise de chaque termitière n’est pas requise. Cette approche constitue une réduction considérable des coûts de missions de terrain liées aux études sur les termitières. [less ▲]

Like elsewhere in the Mediterranean, the olive oil sector is one of the strategic branches of the Moroccan economy owing to its social and economic significance. This research entailed evaluation of the oxidative stability of olive oils made up of a blend of ‘Arbequina’ olive oil with ‘Arbosana’ and ‘Koroneiki’ monovarietal oils known for their high content of natural antioxidants (phenols and tocopherols) and their superior oxidative stability compared with ‘Arbequina’ oil. The monovarietal oils produced from the ‘Arbequina’, ‘Arbosana’ and ‘Koroneiki’ varieties, which have recently been introduced under intensive cultivation in the eastern region of Morocco, underwent physico–chemical characterisation to determine quality criteria, natural antioxidant content, fatty acid composition and triacylglycerol profile. The Rancimat test* was performed to assess the oxidative stability of these monovarietal oils and their three-variety blends. The oxidation tests were performed on five freshly prepared blends (A) of the three varieties – ‘Arbequina’/’Arbosana’/‘Koroneiki’ – according to the following volume ratios: A1: 60/30/10; A2: 60/20/20; A3: 60:10:30; A4: 50:25:25 and A5: 40:30:30. The test results show that blends A4 and A5 displayed the best oxidative stability, recording respective values of 72.67 h and 75.42 h. These results are comparable to those obtained for ‘Arbosana’ monovarietal oil (75.42 h), which is considered to be relatively stable. Hence, blending is an excellent tool for enhancing oils produced from varieties which, despite their excellent initial quality and their organoleptic attributes, are handicapped by their poor stability, as is the case of ‘Arbequina’ oil.

The present guide provides a general method for calculating the thermal rating of overhead lines. It is intended for updating and expanding the Cigré Technical Brochure 207, which only covered the thermal behaviour of overhead conductors at low current densities (<1.5 A/mm2) and low temperatures (<100ºC), and did not consider variations in weather conditions or current with time. In the recent years, various modeling improvements have been developed that take account of these time variations and also of higher currents and higher temperatures, and these have been incorporated into the overall thermal model. Convection and solar radiation models have been improved, as well as more reliable data on the radial and axial temperature distributions, with new examples. These are key factors for the use of dynamic rating systems. [less ▲]

The aquatic environment represents the final sink for many chemicals, including bactericidal agents. Among them Triclosan (TCS) has been shown to affect the thyroid system of teleost. Thyroid hormones are involved in the control of metabolism, so changes in hormone levels induced by triclosan may affect respiratory rates and antioxidant stress in exposed fish. Couples of three females and two males were placed in breeding chambers designed for this experiment. Eggs were collected and maintained in seawater. Embryos were selected under a dissection microscope, randomly assigned to each of five treatment groups: Control, DMSO control, 20 μg/L TCS, 50 μg/L TCS and 100 μg/L TCS and placed in incubation dishes (50 per dish) at 25°C. On day 6, embryos hatched and larvae were transferred to 1L dishes. The larvae were fed on artemias and on flaked fish food till day 15 and 30 post hatching when the fish were analyzed. Respiratory rate measurements were carried out by respirometry and assays of antioxidant enzymes, Glutathionreductase (GR), glutathione peroxidase (GPx) and glutathione-S-transferase (GST) were conducted to determine the presence of oxidative stress. Respirometry showed that TCS exposed fish exhibited decreased the metabolism at 15 dph, whereas no differences in respiration rate could be observed between control and exposed larvae at 30 dph. At 15 dph no difference was observed for any of the antioxidant enzymes, whereas at 30 dph a sharp increase in the activity of GR was observed between the control and TCS exposed fish. The activity of GST and Gpx remained stable. Thyroid hormones are major factors controlling the metabolic rate related to respiration and oxidative stress. TCS reduced the metabolism at 15 dph that corresponds to the moment where larvae to juvenile transition of Sheepshead minnows occur. Previous experiments showed that TCS induces an increase in thyroid hormone concentrations and hyperthyroidism induces oxidative stress. So our observed increase of antioxidant protection mechanisms could be a way to compensate oxidative stress. On the other hand, the changes in GR activity observed at 30 dph, may also be related to the reduced metabolism at 15 dph. [less ▲]
