Unraveling the Essential Effects of Flocculation on Large-Scale Sediment Transport Patterns in a Tide-Dominated Estuary
Horemans, D. et al. (2020) Unraveling the Essential Effects of Flocculation on Large-Scale Sediment Transport Patterns in a Tide-Dominated Estuary, Journal of Physical Oceanography, (7): 1957–1981
Sediment transport in estuaries and the formation of estuarine turbidity maxima (ETM) highly depend on the ability of suspended particulate matter (SPM) to flocculate into larger aggregates. While most literature focuses on the small-scale impact of biological flocculants on the formation of larger aggregates, the influence of the flocculation process on large-scale estuarine SPM profiles is still largely unknown. In this paper, we study the impact of flocculation of SPM on the formation of ETM.
Use of calixarenes bearing diazonium groups for the development of robust monolayers with unique tailored properties
Troian-Gautier, L, Mattiuzzi, A., Reinaud, O., Lagrost, C. and Jabin, I (2020) Use of calixarenes bearing diazonium groups for the development of robust monolayers with unique tailored properties. Organic & Biomolecular Chemistry (The Royal Society of Chemistry), Issue 19
Surface modification represents an active field of research that finds applications, amongst others, in the development of medical devices, sensors and biosensors, anti-biofouling materials, self-cleaning surfaces, surfaces with controlled wettability, corrosion resistance, heterogeneous catalysis and microelectronics. For some applications, surface functionalization with a nanometric-size monolayer is desired. In this review, efforts to covalently functionalize a wide array of surfaces with calixarenes bearing diazonium groups are described.
‘With or Without You’: The Governance of (Local) Security and the Koglweogo Movement in Burkina Faso
Leclercq, S. and Matagne, G. (2020) ‘With or Without You’: The Governance of (Local) Security and the Koglweogo Movement in Burkina Faso. Stability: International Journal of Security and Development, 9(1), p.4. DOI: http://doi.org/10.5334/sta.716
In late 2014 and after more than two decades of a ‘semi-authoritarian’ regime, a popular insurrection in Burkina Faso led to the fall of Blaise Compaoré, president and leader of the ruling party. Due to — or parallel to — the political transition, factors of insecurity developed or were amplified, leading to a reconfiguration of the provision of security at two levels. At the central state level began a reflection around the governance model of security and the improvement of the practices of state security forces. At the local level, non-state security initiatives have multiplied.
Accurate Detection of Dobutamine-induced Haemodynamic Changes by Kino-Cardiography: A Randomised Double-Blind Placebo-Controlled Validation Study
Hossein, A. (2019) Accurate Detection of Dobutamine-induced Haemodynamic Changes by Kino-Cardiography: A Randomised Double-Blind Placebo-Controlled Validation Study. Scientific Reports, 9, Article number: 10479.
Non-invasive remote detection of cardiac and blood displacements is an important topic in cardiac telemedicine. Here we propose kino-cardiography (KCG), a non-invasive technique based on measurement of body vibrations produced by myocardial contraction and blood flow through the cardiac chambers and major vessels. KCG is based on ballistocardiography and measures 12 degrees-of-freedom (DOF) of body motion. We tested the hypothesis that KCG reliably assesses dobutamine-induced haemodynamic changes in healthy subjects.
An Analysis of the Early Regeneration of Mangrove Forests using Landsat Time Series in the Matang Mangrove Forest Reserve, Peninsular Malaysia
Otero, V. et al. (2019) An Analysis of the Early Regeneration of Mangrove Forests using Landsat Time Series in the Matang Mangrove Forest Reserve, Peninsular Malaysia. Remote Sensing , 11(7), 774; https://doi.org/10.3390/rs11070774
Time series of satellite sensor data have been used to quantify mangrove cover changes at regional and global levels. Although mangrove forests have been monitored using remote sensing techniques, the use of time series to quantify the regeneration of these forests still remains limited.

Citizenship Pressure as a Predictor of Daily Enactment of Autonomous and Controlled Organizational Citizenship Behavior: Differential Spillover Effects on the Home Domain
Germeys, L. et al. (2019) Citizenship Pressure as a Predictor of Daily Enactment of Autonomous and Controlled Organizational Citizenship Behavior: Differential Spillover Effects on the Home Domain. Frontiers in Psychology https://doi.org/10.3389/fpsyg.2019.00395.
This study questions the exclusive discretionary nature of organizational citizenship behavior (OCB) by differentiating between autonomous OCB (performed spontaneously) and controlled OCB (performed in response to a request from others). We examined whether citizenship pressure evokes the performance of autonomous and controlled OCB, and whether both OCB types have different effects on employees’ experience of work-home conflict and work-home enrichment at the within- and between-person level of analysis.
Van Nieuwenhove, A. et al. (2019) Cryptic diversity and limited connectivity in octopuses: Recommendations for fisheries management. Plos One, May 2019.
The market demand for octopus grows each year, but landings are decreasing, and prices are rising. The present study investigated (1) diversity of Octopodidae in the Western Indian Ocean (WIO) and (2) connectivity and genetic structure of Octopus cyanea and O. vulgaris populations in order to obtain baseline data for management plans. A fragment of the cytochrome C oxidase subunit 1 (COI) gene was sequenced in 275 octopus individuals from Madagascar, Kenya and Tanzania.
Detecting neurodegenerative pathology in multiple sclerosis before irreversible brain tissue loss sets in
Van Schependom, J. et al. Detecting neurodegenerative pathology in multiple sclerosis before irreversible brain tissue loss sets in. Transl Neurodegener 8, 37 (2019) doi:10.1186/s40035-019-0178-4 and 9, 3 (2020) doi:10.1186/s40035-019-0182-8.
Food Consumption in Adolescents and Young Adults: Age-Specific Socio-Economic and Cultural Disparities (Belgian Food Consumption Survey 2014)
Desbouys, L.; De Ridder, K.; Rouche, M.; Castetbon, K. (2019) Food Consumption in Adolescents and Young Adults: Age-Specific Socio-Economic and Cultural Disparities (Belgian Food Consumption Survey 2014). Nutrients, 11, 1520.
A key issue in nutritional public health policies is to take into account social disparities behind health inequalities. The transition from adolescence toward adulthood is a critical period regarding changes in health behaviors. This study aimed to determine how consumption of four emblematic food groups (two to favor and two to limit) differed according to socio-economic and cultural characteristics of adolescents and young adults living in Belgium.
Schoelynck, J. e.a. (2019) Hippos (Hippopotamus amphibius): The animal silicon pump, Science Advances 01 May 2019: Vol. 5, no. 5, eaav0395 DOI: 10.1126/sciadv.aav0395.
While the importance of grasslands in terrestrial silicon (Si) cycling and fluxes to rivers is established, the influence of large grazers has not been considered. Here, we show that hippopotamuses are key actors in the savannah biogeochemical Si cycle. Through a detailed analysis of Si concentrations and stable isotope compositions in multiple ecosystem compartments of a savannah-river continuum, we constrain the processes influencing the Si flux. Hippos transport 0.4 metric tons of Si day−1 by foraging grass on land and directly egesting in the water.

Opsomer, S. et al. (2019) Resilience in middle-aged partners of patients diagnosed with incurable cancer: A thematic analysis. PLoS One, Aug. 14, 2019.
Background Providing care for patients with advanced cancer is often the responsibility of the partner. Being confronted with an incurable cancer diagnosis can be highly disruptive for the patient’s partner and can be considered a potentially traumatic event. However, most caregivers seem to adapt well during the process of providing care. This finding is in line with the concept of resilience in literature: a dynamic process of adapting well, resulting from the interplay between intrinsic and extrinsic resources and risks.
Temperature preference of Nile tilapia (Oreochromis niloticus) juveniles induces spontaneous sex reversal
Nivelle R. et al. (2019) Temperature preference of Nile tilapia (Oreochromis niloticus) juveniles induces spontaneous sex reversal. PLoS ONE 14(2): e0212504. https://doi.org/10.1371/journal.pone.0212504
Nile tilapia (Oreochromis niloticus) is an African freshwater fish that displays a genetic sex determination system (XX|XY) where high temperatures (above 32°C to 36.5°C) induce masculinization. In Nile tilapia, the thermosensitive period was reported from 10 to 30 days post fertilization. In their natural environment, juveniles may encounter high temperatures that are above the optimal temperature for growth (27–30°C). The relevance of the thermal sex reversal mechanism in a natural context remains unclear.
