Economic importance of the Belgian ports: Flemish maritime ports, Liège port complex and the port of Brussels – Report 2013. National Bank of Belgium Working Paper No. 283

This paper is an annual publication issued by the Microeconomic Analysis service of the National Bank of Belgium. The Flemish maritime ports (Antwerp, Ghent, Ostend, Zeebrugge), the Autonomous Port of Liège and the port of Brussels play a major role in their respective regional economies and in the Belgian economy, not only in terms of industrial activity but also as intermodal centres facilitating the commodity flow. This update paper1 provides an extensive overview of the economic importance and development of the Flemish maritime ports, the Liège port complex and the port of Brussels for the period 2008 - 2013, with an emphasis on 2013. Focusing on the three major variables of value added, employment and investment, the report also provides some information based on the social balance sheet and an overview of the financial situation in these ports as a whole. These observations are linked to a more general context, along with a few cargo statistics. Annual accounts data from the Central Balance Sheet Office were used for the calculation of direct effects, the study of financial ratios and the analysis of the social balance sheet. The indirect effects of the activities concerned were estimated in terms of value added and employment, on the basis of data from the National Accounts Institute. As a result of the underlying calculation method the changes of indirect employment and indirect value added can differ from one another. The developments concerning economic activity in the six ports in 2012 - 2013 are summarised in the table on the next page. The overall decline in maritime traffic seen in the Flemish maritime ports in general in 2012, and in each individual port, was reversed in 2013, but only thanks to growth in Antwerp; the other three ports (Ghent, Ostend and Zeebrugge) experienced a further decrease. In terms of value added, the opposite occurred: a general increase, except in Antwerp, resulting in a slight rise for these ports as a whole. The employment picture was variable, but there was expansion overall, matching the growth of value added, namely 0.3 %. Finally, investment in the Flemish ports declined overall, totalling 3.2 % less in 2013 than in the previous year. In the ports of Liège and Brussels, cargo traffic and employment both declined in 2013. After the sharp fall in 2012, value added at the port of Liège edged upwards again, but in Brussels it recorded a significant decline2. Conversely, investment in Liège was down again, following the surge in 2012, whereas the port of Brussels saw a substantial increase. This report provides a comprehensive account of these issues, giving details for each economic sector, although the comments are confined to the main changes that occurred in 2013

A novel hybrid 3D endoscope zooming and repositioning system : design and feasibility study

Background: Manipulation of the endoscope during minimally invasive surgery is a major source of inconvenience and discomfort. This report elucidates the architecture of a novel one-hand controlled endoscope positioning device and presents a practicability evaluation. Methods and materials: Setup time and total surgery time, number and duration of the manipulations, side effects of three-dimensional (3D) imaging, and ergonomic complaints were assessed by three surgeons during cadaveric and in vivo porcine trials. Results: Setup was accomplished in an average (SD) of 230 (120) seconds. The manipulation time was 3.87 (1.77) seconds for angular movements and 0.83 (0.24) seconds for zooming, with an average (SD) of 30.5 (16.3) manipulations per procedure. No side effects of 3D imaging or ergonomic complaints were reported. Conclusions: The integration of an active zoom into a passive endoscope holder delivers a convenient synergy between a human and a machine-controlled holding device. It is shown to be safe, simple, and intuitive to use and allows unrestrained autonomic control of the endoscope by the surgeon

Gelatin-based hydrogels promote chondrogenic differentiation of human adipose tissue-derived mesenchymal stem cells in vitro

Due to the weak regeneration potential of cartilage, there is a high clinical incidence of articular joint disease, leading to a strong demand for cartilaginous tissue surrogates. The aim of this study was to evaluate a gelatin-based hydrogel for its suitability to support chondrogenic differentiation of human mesenchymal stem cells. Gelatin-based hydrogels are biodegradable, show high biocompatibility, and offer possibilities to introduce functional groups and/or ligands. In order to prove their chondrogenesis-supporting potential, a hydrogel film was developed and compared with standard cell culture polystyrene regarding the differentiation behavior of human mesenchymal stem cells. Cellular basis for this study were human adipose tissue-derived mesenchymal stem cells, which exhibit differentiation potential along the adipogenic, osteogenic and chondrogenic lineage. The results obtained show a promotive effect of gelatin-based hydrogels on chondrogenic differentiation of mesenchymal stem cells in vitro and therefore encourage subsequent in vivo studies

Endovascular techniques in the management of acute arterioenteric fistulas

Purpose: To report the use of endovascular techniques to emergently treat hemorrhagic complications of rare arterioenteric fistulas. Case Reports: Two patients, a 71-year-old man and a 61-year-old woman, presented with acute bleeding arising from primary arterioenteric fistulas. In the first patient, a fistula between the iliac artery and the small intestine complicated laparoscopic treatment of acute appendicitis. In the second patient, irradiation of a metastatic cervical carcinoma led to a fistula between the right iliac artery and the terminal ileum. In both patients, the hemorrhage was controlled with implantation of a Jostent Peripheral Stent-Graft. The man is alive at 3 years with a patent endograft, but the woman died 1 month after treatment from complications of tumor progression. Conclusions: Endovascular application of covered stents provides an alternative treatment, avoiding extensive surgery. In cases of neoplastic erosion of a large vessel, endovascular stenting can offer a palliative solution

Airborne monitoring of compliance to sulfur emission regulations by ocean-going vessels in the Belgian North Sea area

Air pollution from fossil fuel powered ocean-going vessels (OGVs) is responsible for various environmental and human health issues worldwide. Specifically for sulfur oxides (SOx), from 2010 onwards, stricter standards came into force regarding the maximum allowable fuel sulfur content (FSC) in marine fuels in the European Sulfur Emission Control Area (SECA). A method was developed for the airborne monitoring of OGVs to evaluate their compliance by equipping the Belgian coastguard aircraft with a sniffer sensor. The sensor allows a highly accurate FSC determination based on real-time CO2 and SO2 measurements in the smoke plume of OGVs. For 5 years the aircraft collected the largest set of airborne emission measurement data from OGVs as of today. This article demonstrates the effectiveness and reliability of the airborne monitoring methodology in an operational setup for targeting ship inspections in ports and a more efficient impact monitoring of shipping on air quality

Airborne monitoring of compliance to NOx emission regulations from ocean-going vessels in the Belgian North Sea

Along the worldwide tightening of standards for sulphur emission from ocean going vessels (OGVs) come actions that are also being taken to reduce nitrogen emission. Particularly, as a milestone in this regard, on January 1st, 2021 the NOx Emission Control Area (NECA) for the North Sea and Baltic Sea came into effect. In response to the newly established NECA, the sniffer sensor system on the Belgian coastguard aircraft was modified and extended with a NO(x )sensor. Moreover, a methodology was developed to evaluate OGV compliance to the NO(x )emission limits through in situ measurements of the plume exhaust. The quality and uncertainty of the measurements demonstrate that it is likely to achieve an effective compliance monitoring of the NOx emission standards on the sea. Those emission standards are further divided into four tiers depending on the keel laying date. As has been proved by the results, NOx emissions for Tier II OGVs, contrary to what might be expected, are on average higher than those for Tier I OGVs. What is even more problematic, Tier II OGVs have also more often been found to be non-compliant than Tier I OGVs
