An in-depth understanding of the main factors behind built-up development is a key prerequisite for designing policies dedicated to a more efficient land use. Infill development policies are essential to curb sprawl and allow a progressive recycling of low-density areas inherited from the past. This paper examines the controlling factors of built-up expansion and densification processes in Wallonia (Belgium). Unlike the usual urban/built-up expansion studies, our approach considers various levels of built-up densities to distinguish between different types of developments, ranging from low-density extensions (or sprawl) to high-density infill development. Belgian cadastral data for 1990, 2000, and 2010 were used to generate four classes of built-up areas, namely, non-, low-, medium- and high-density areas. A number of socioeconomic, geographic, and political factors related to built-up development were operationalized following the literature. We then used a multinomial logistic regression model to analyze the effects of these factors on the transitions between different densities in the two decades between 1990 and 2010. The findings indicate that all the controlling factors show distinctive variations based on density. More specifically, the centrality of zoning policies in explaining expansion processes is highlighted. This is especially the case for high-density expansions. In contrast, physical and neighborhood factors play a larger role in infill development, especially for dense infill development. [less ▲]

The predominant production model of Bioenergy, which is based on first-generation biofuels developed on a global scale, creates ecological impacts throughout the production chain, resulting in a paradox, as well as social unrest and territorial conflict. This paper focuses on agro-energy and second-generation biofuels, investigating the structural differences, the advantages, the potential problems and the possible solutions of some local biofuel initiatives in North-Western Europe.

Recent theoretical accounts of verbal and visuo-spatial short-term memory (STM) have proposed the existence of domain-general mechanisms for the maintenance of serial order information. These accounts are based on the observation of similar behavioural effects across several modalities, such as temporal grouping effects. Across two experiments, the present study aimed at extending these findings, by exploring a STM modality that has received little interest so far, STM for musical information. Given its inherent rhythmic, temporal and serial organisation, the musical domain is of interest for investigating serial order STM processes such as temporal grouping. In Experiment 1, the data did not allow to determine the presence or the absence of temporal grouping effects. In Experiment 2, we observed that temporal grouping of tone sequences during encoding improves short-term recognition for serially presented probe tones. Furthermore, the serial position curves included micro-primacy and micro-recency effects, which are the hallmark characteristic of temporal grouping. Our results suggest that the encoding of serial order information in musical STM may be supported by temporal positional coding mechanisms similar to those reported in the verbal domain. [less ▲]

Objective: We here aimed at characterizing heart–brain interactions in patients with disorders of consciousness. We tested how this information impacts data-driven classification between unresponsive and minimally conscious patients. Methods: A cohort of 127 patients in vegetative state/unresponsive wakefulness syndrome (VS/UWS; n570) and minimally conscious state (MCS; n557) were presented with the local–global auditory oddball paradigm, which dis- tinguishes 2 levels of processing: short-term deviation of local auditory regularities and global long-term rule viola- tions. In addition to previously validated markers of consciousness extracted from electroencephalograms (EEG), we computed autonomic cardiac markers, such as heart rate (HR) and HR variability (HRV), and cardiac cycle phase shifts triggered by the processing of the auditory stimuli. Results: HR and HRV were similar in patients across groups. The cardiac cycle was not sensitive to the processing of local regularities in either the VS/UWS or MCS patients. In contrast, global regularities induced a phase shift of the cardiac cycle exclusively in the MCS group. The interval between the auditory stimulation and the following R peak was significantly shortened in MCS when the auditory rule was violated. When the information for the cardiac cycle modulations and other consciousness-related EEG markers were combined, single patient classification performance was enhanced compared to classification with solely EEG markers. Interpretation: Our work shows a link between residual cognitive processing and the modulation of autonomic somatic markers. These results open a new window to evaluate patients with disorders of consciousness via the embodied paradigm, according to which body–brain functions contribute to a holistic approach to conscious processing.

BACKGROUND The prognosis value of early clinical diagnosis of consciousness impairment is documented by an extremely limited number of studies, whereas it may convey important information to guide medical decisions. OBJECTIVE We aimed at determining if patients diagnosed at an early stage (<90 days after brain injury) as being in the minimally conscious state (MCS) have a better prognosis than patients in the vegetative state/Unresponsive Wakefulness syndrome (VS/UWS), independent of care limitations or withdrawal decisions. METHODS Patients hospitalized in ICUs of the Pitié-Salpêtrière Hospital (Paris, France) from November 2008 to January 2011 were included and evaluated behaviourally with standardized assessment and with the Coma Recovery Scale-Revised as being either in the VS/UWS or in the MCS. They were then prospectively followed until 1July 2011 to evaluate their outcome with the GOSE. We compared survival function and outcomes of these two groups. RESULTS Both survival function and outcomes, including consciousness recovery, were significantly better in the MCS group. This difference of outcome still holds when considering only patients still alive at the end of the study. CONCLUSIONS Early accurate clinical diagnosis of VS/UWS or MCS conveys a strong prognostic value of survival and of consciousness recovery. [less ▲]

Space is lived individually and collectively and can become a source of existential affectation, especially when the lived experience is modified by disease. The fact that the hospital is also a place of territorialisation can potentiate this affectation, with at times surprizing consequences. We aim –based on a reflection about the relationship patients and clinicians establish with the territory of the hospital- to identify some psychological and existential issues at stake with regard to space as a social construction.

Summary Introduction: In developing countries, quality of prison life remains a challenge in public health. The present study aimed at determining the quality of life as perceived by inmates during their imprisonment at the Central Prison of Mbuji-Mayi, Democratic Republic of Congo. Materials and Methods: This cross-sectional study was carried out over a 3-month period (between December 2015 and February 2016) at the Central Prison of Mbuji-Mayi. Three hundred inmates participated to the survey. The World Health Organisation Quality of Life Scale (WHOQOL-BREF) was used to estimate health and problems affecting inmates’ everyday life. Results: Mean age of inmates was 33 ± 10 years (range: 18-70 years) and most of them were male (88.7%). The quality of life score they estimated was below 50, on the WHOQOL-BREF scale weighted over 100 points (average overall score: 26±7). When considering each WHOQOL-BREF domain, the lowest scores (0-100 normalised scale) were registered for: perception of physical health (24±11), psychological health (18±8), social relationship (39±15) and environmental relationships (24±8). Overall, inmates aged over 30 years old presented an average score slightly lower than younger inmates (25±6 vs. 27±7; p=0.005). Depending on the length of incarceration, the average score was lower for inmates imprisoned for more than 6 months compared to others (26±6 vs. 28 ± 8; p= 0.015). Correlations between domain scores were low but statistically significant; no correlation was highlighted between environment and mental health domains. Conclusion: Most inmates considered their quality of life as negative, regardless of the WHOQOL-BREF domain. Efforts to improve quality of life should remain a priority for political authorities.

The cyanobacterial genus Arthrospira appears very conserved and has been divided into five main genetic clusters on the basis of molecular taxonomy markers. Genetic studies of seven Arthrospira strains, including genome sequencing of seven strains, have enabled a better understanding of those photosynthetic prokaryotes. Even though genetic manipulations have not yet been performed with success, many genomic and proteomic features such as stress adaptation, nitrogen fixation or biofuel production have been characterized. Many of above-mentioned studies aimed to optimize the cultivation conditions. Factors like the light intensity and quality, the nitrogen source or different modes of growth (auto-, hetero- or mixotrophic) have been studied in detail. The scaling-up of the biomass production using photobioreactors, either closed or open, was also investigated to increase the production of useful compounds.. The richness of nutrients contained in the genus Arthrospira can be used for promising applications in the biomedical domain. Ingredients such as the calcium spirulan, immulina, C‐phycocyanin and γ‐linolenic acid (GLA) show a strong biological activity. Recently, its use in the fight against cancer cells was documented in many publications. The health-promoting action of 'Spirulina' has been demonstrated in the case of cardiovascular diseases and age-related conditions. Some compounds also have potent immunomodulatory properties, promoting the growth of beneficial gut microflora, acting as antimicrobial and antiviral. Products derived from Arthrospira were shown to successfully replace biomaterial scaffolds in regenerative medicine. Supplementation with the cyanobacterium also improves the health of livestock and quality of the products of animal origin. They were also used in cosmetic preparations. [less ▲]

The starting point for this paper are the archives produced by the so-called Council of Troubles, the special court established by Philip II in response to the uprising and misbehaviour of parts of the population of the Low Countries in the years 1566–1567. This institution remained active from 1567 to 1576 and was commanded by the Duke of Alva. In particular, being well aware of the potential of those cultural objects and carriers of ideas, it watched very closely the production, the distribution as well as the possession of books. The documents contain inventories of thousands of books – either forbidden or not – found in bookshops located in the southern provinces. I will focus my paper on the 12 bookshops located in Brussels visited in 1568 by religious authorities, and especially in that of Michiel van Hamont, printer from 1557 to 1585. The repressive measures taken by the Duke of Alva will be the entry point of a study on the state of book culture in Brussels during the last third of the sixteenth century. [less ▲]

Introduction: Some clinical series have previously evaluated the effect of PRP in the treatment of proximal patellar tendinopathies. Although it is possible that a single infiltrative administration may prove to be an effective treatment for this indication, most of the existing studies evaluated the effects of successive infiltrations which is arguably likely to increase the risks of complications. Methods: Our study is a single blinded, randomized controlled clinical trial on 20 leisure sportsmen (2 groups, respectively 1 or 2 infiltrations of pure PRP) with chronic proximal patellar tendinopathies, rebel to classical management. PRP was obtained using an aphaeresis machine. The one-year follow-up evaluation consisted of VAS, IKDC and VISA-P scores, while algometer, isokinetic and ultrasounds evaluations were carried out up to 3 months. Results: The concentration of the PRP used was similar in both groups. The VAS significantly decreased with time over the 3-month follow-up period (p=0.002), with no difference observed between the two groups (p=0.2). Values obtained with the pressure algometer increased with time across both groups over the 3-month follow-up period (p<0.0001), and values were significantly higher for Group 1 (p=0.001). The IKDC score increased with time in both groups over the follow-up period (p=0.034), with values again significantly higher for Group 1 (p=0.0026). The VISA-P score increased with time in both groups over the follow-up period (p=0.0023), with no difference observed between the groups (p=0.41). No improvements in isokinetic physical performance were observed in either group. However, pain during E30 significantly decreased over the 3-month follow-up period (p=0.027) for patients in both groups. No improvement in either jumping performances or in pain was observed in either group during opto-jump evaluation. No improvements in US findings were observed. After one year, 90% patients of group 1 did not report anymore pain during daily activities, in comparison with only 20% in group 2. Conclusions: A second closely-timed infiltration of PRP to treat proximal patellar tendinopathies is not necessary to improve the efficacy of this treatment. [less ▲]

Introduction : Acute hamstring injury is a very common muscle injury particularly in sports that require high explosive strength, sports with impulsions and sports with running phases. Among those sports, the most widespread are soccer, rugby and sprinting. The Functional Assessment Scale for acute Hamstring injuries (FASH) assesses pain, physical activity and how patients realize some exercises while suffering hamstring injury. Current available versons are in English, in German and in Greek. Objectives : The aims of thus study were to reach a reliable and valid translation and a cross-cultural adaptation of this questionnaire in French. Methods: FASH translation and adaptation were realized in respect of international guidelines. The population composed of 116 subjects filled the questionnaire twice separated by 48-60th. FASH reliability and validity were assessed thanks to SF-36 allowing us to assess the test re-test reliability (with intra-class correlation ICC), internal consistency (with Cronbach’s alpha coefficient and construct validity, with Spearman’s correlation coefficients). Results : ICC showed a strong correlation between test and re-test (ICC total=0.9985). Internal consistency was also found to be strong with Cronbach’s alpha coefficient = 0.98. Correlation between FASH and SF-36 overall score was considered as strong (Rs=0.69, p<0.0001). Correlation with SF-36 sub scales (PF, RP, BP) were also considered as strong, showing their convergent validity. Other SF-36 subclass (GH, MH, REm, SF, VT) displayed a moderate correlation with FASH questionnaire, showing their divergent validity. No floor or ceiling effect was observed. Conclusions: FASH translation and cross-cultural adaptation into French can be considered as successful. FASF-F is now a reliable and valid tool for patients suffering acute hamstring injury.
