In België bestaat er een nauwe band tussen talen (Nederlands-Frans) en regionale identiteiten (Vlaming-Waal). Echter, de aanwezigheid van Franstaligen in Vlaanderen en van Nederlandstaligen in Wallonië laat zien dat deze band niet automatisch is. Deze twee (onder)bevolkingsgroepen lijken dus een ideaal studiemateriaal om de ingewikkelde relatie tussen taal (talen) en identiteit(en) te bestuderen. Ondanks de belangstelling van verschillende disciplines (onder meer politieke wetenschappen, geschiedenis, sociologie en taalkunde) voor dit onderwerp, valt het toch op dat deze bevolkingsgroepen nog nooit onderzocht werden. In dit onderzoeksproject willen we daarom aan de hand van biografische gesprekken nagaan (i) hoe deze minoriteitsgroepen in een anderstalige context hun identiteit opbouwen, en (ii) in hoeverre ze identiteitsstrategieën gebruiken naargelang van de communicatiecontext waarin ze zich bevinden. Om deze vragen te beantwoorden, zullen biografische gesprekken verzameld worden die die vanuit het interdisciplinaire perspectief van de sociologie, de sociale psychologie, de sociolinguïstiek en de taalkunde geanalyseerd zullen worden. In deze bijdrage zullen we specifieker ingaan op de methodologie die wij zullen gebruiken om deze biografische gesprekken te analyseren. We zullen meer bepaald uitgaan van een tweeledige analyse van identiteitsmarkeerders. Ten eerste zullen we een semantische studie van de identiteitscategorieën verrichten, door de lexicale eenheden te bestuderen die door de informanten gebruikt worden om hun identiteit te omschrijven. Het is hiermee de bedoeling om de sociale categorieën die de respondenten gebruiken verder in kaart te brengen. Ten tweede zullen wij een psychosociale studie van de identiteitsstrategieën van de informanten verrichten. Vanuit dit perspectief kan een identiteit beschouwd worden als het resultaat van de interactie tussen een “identiteit voor zichzelf” en een “identiteit voor de anderen”. In dit onderdeel van onze studie willen we de persoonlijke identiteitsstrategieën van de informanten aan het licht brengen onder meer door hun identiteitskeuzes, zoals bijvoorbeeld de keuze voor een taalvariëteit in een bepaalde communicatiecontext, nauwkeurig te bestuderen. Deze tweedelige methode zal het mogelijk maken om de relatie tussen taal en identiteit in België beter te begrijpen en nauwkeuriger te kunnen omschrijven. [less ▲]

Introduction: The aesthetic results of implant restoration in the anterior maxilla are particularly related to the soft tissue profile. Although socket preservation techniques appear to reduce bone remodelling after tooth extraction, there is still few investigations assessing the external soft tissue profile after such procedures. The goal of the present study was to describe an accurate technique to evaluate soft tissue contour changes after performing socket preservation procedures. The secondary objective was to apply the newly develop measuring method to a specific socket preservation using a “saddled” connective tissue graft combined with the insertion of slowly resorbable biomaterials into the socket. Materials and Methods: A total of 14 patients needing tooth replacement in the aesthetic region were included to receive a socket preservation procedure using a connective tissue graft. Impressions were taken before the tooth extraction (baseline) and at 2, 4, and 12 weeks after the procedure. The corresponding plaster casts were scanned, and the evolution of the soft tissue profile in relation to the baseline situation was assessed using imaging software. Results: The measuring technique allowed assessing the soft tissue profiles accurately at different level of the alveolar process. The insertion of a saddled connective tissue appeared to compensate significantly for the horizontal and vertical bone remodelling after a socket preservation procedure in most regions of the alveolar crest. After 12 weeks, the only significant change was located in the more cervical and central region of the alveolar process and reached a mean of 0.76 mm. Conclusion: Within the limitations of this study, we found that a saddled connective tissue graft combined with a socket preservation procedure could almost completely counteract the bone remodelling in terms of the external soft tissue profile. The minor changes found in the cervical region might disappear with the emergence profile of the prosthodontic components. The described technique might therefore enhance the aesthetic outcomes when a tooth has to be replaced in the aesthetic zone. The described protocol can be used to further compare the effectiveness of different extraction socket preservation protocols in randomised controlled trials. [less ▲]

AIMS: Multiple surgical protocols using biomaterials have been proposed to limit the typical post-extraction bone resorption. However, because of the heterogeneity of the studies, particularly the differences in assessment methods, it is difficult to determine the superiority of one technique over another. The objective of this study was to describe a new radiographic method to draw a map of alveolar bone remodelling after alveolar ridge preservation procedures to compare different surgical techniques more accurately. The newly developed measuring method was applied to a case series describing a specific preservation technique. MATERIALS AND METHODS: Fourteen extraction sites (in 14 patients) located in the upper anterior maxilla were treated with bovine hydroxyapatite (0.25- to 1-mm particles) and a saddled connective tissue graft. A radiographic three-dimensional assessment of the hard tissues was performed at baseline and 3 months after the procedure. Standardized horizontal measurements were taken at three corono-apical levels (-2, -5 and -9 mm) and at three mesio-distal levels (mesial, centre and distal) in the buccal and palatal aspects. Vertical measurements were also recorded in nine regions superior to the alveolar crest. The measurements were performed by two independent observers and intra- and inter-observer effects were evaluated. RESULTS: No inter- and intra-observer effects were found when analysing the measurements from these two observers. The horizontal dimension of the crest decreased by 1.6 mm (20%) in the cervical regions (-2 mm level), decreased moderately, by 1 mm (12%), at the -5 mm level and decreased very little, 0.5 mm (6%), at the apical (-8 mm) level. The losses were always significantly higher in the buccal than in the palatal aspect. Buccally, the maximal bone remodelling at the cervical level remained below 1 mm. Vertical bone resorption was homogeneous and<1 mm in the nine measured regions. DISCUSSION: The radiographic measuring methodology proved to be reproducible. It can be applied in other clinical settings. It successfully assessed the alveolar ridge preservation technique (BHA+saddle connective tissue graft). [less ▲]

About 6% of global CO2 emissions are due to cement production. Blending of Portland cement with a significant fraction of mineral admixture could therefore be instrumental in reducing such emissions. Use of an admixture of vegetable origin such as rice husk as will additionally contribute to waste management and its incineration produces energy. This paper will stress the importance of properly designing such blends. Preferably gap-graded concepts should be employed, since blending efficiency in terms of strength development is promoted as shown in earlier publications. The paper therefore only briefly covers these aspects. Assessment of this blending concept on durability of cementitious materials constitutes a far more complicated problem. This requires careful porosimetry. Mostly, this problem is approached by MIP or by quantitative image analysis. Both can provide 3D information, although that of MIP is generally significantly biased. Quantitative image analysis is however time-consuming and laborious, and thus expensive. Moreover, it does not provide information on continuity of pores. Present day computer facilities offer therefore a better alternative. When using a proper DEM system, the concrete can be simulated in a realistic way. The paper describes new methods for investigating the pore structure in virtual concrete and presents some data on pure cement and blended cement. Differences will have impact on durability risks.

Radio tracking has been extensively used to enhance our knowledge on the movement and home range of fish in general and salmonids in particular. However, the use of various temporal sampling protocols is likely to overlook fish movements, and produce experimental artefacts, the amplitude of which is unknown and may compromise comparison of fish behaviours revealed by different protocols. Starting from a day-by-day tracking study of brown treat in Belgian waters (Aisne stream, nine fish, minimum 39 daily locations per fish), we re-examined their home range and mobility, through a subsampling process, as if the fish had been located at longer time intervals (2-14 days). The estimates from subsamples were compared to the original data set in order to quantify the corresponding reduction of accuracy from observed data, and how far this could be predicted on the basis of locating frequency. The results clearly indicate that all intervals longer than one day generally generate substantial biases (reduction of accuracy from 0 to 82% for home range and from 5 to 92% for mobility) but these can be partly corrected through the use of predictive models. This analysis demonstrates that any comparison between studies relying on different locating frequencies can generate some ambiguity when interpreting biological phenomena or geographical differences.
