Gent, Belgium

University College Ghent is the largest university college in Flanders, with three faculties, one School of Arts and 13,000 students. Its establishment in 1995 is the outcome of two successful mergers that involved sixteen Belgian institutions of higher education. Many had been influential leaders in higher education for several decades. The current faculties are spread over the city center of Ghent and Aalst. Wikipedia.

To investigate the passive properties of the plantar flexors muscle-tendon tissue in patients with the hypermobility type of Ehlers-Danlos syndrome (EDS-HT). Twenty-five women with EDS-HT and 25 sex- and age-matched healthy control subjects participated in the study. Passive resistive torque (PRT) of the plantar flexors was measured with an isokinetic dynamometer during 2 standardized stretch protocols to obtain the passive muscle tension. Protocol 1 consisted of 4 continuous cycles to a predetermined angle of 10° dorsiflexion. Protocol 2 consisted of a slow stretch to the onset of pain. Torque, angle, and electromyography were simultaneously recorded during the tests. To take muscle thickness into account, muscle cross-sectional area (MCSA) was obtained with peripheral quantitative computed tomography. Stiffness of the Achilles tendon was assessed using a dynamometer in combination with ultrasonography. The results demonstrate a significantly larger maximal joint angle in the EDS-HT patients accompanied by a similar PRT compared to the control subjects (protocol 2), indicating a lower passive muscle tension in the patient group. PRT for the predetermined angle (protocol 1) was the same for both groups and there was no difference in MSCA. Furthermore, a significantly lower Achilles tendon stiffness was seen in the patient group than in the control group. This study is the first to provide evidence for altered passive properties of the muscle-tendon unit in EDS-HT patients. These changes are thought to be associated with structural modifications in connective tissue. Copyright © 2012 by the American College of Rheumatology. Source

Adhesive capsulitis is, in most cases, a self-limiting condition of poorly understood etiology that results in shoulder pain and large mobility deficits. The socio-economic burden will increase as with continuous aging of our population. In addition, both prevalence and incidence figures of adhesive capsulitis are increasing. No literature overview solely focuses on the physiotherapeutic options in patients with adhesive capsulitis and their scientific evidence. Moreover, although some physiotherapeutic interventions show evidence regarding reducing pain or increasingmobility, there is little evidence to suggest that the disease prognosis is affected and this raises the need for new, innovative research in the area of adhesive capsulitis and its treatment. By presenting its current evidence, we hope to retrieve several gaps in the present management of adhesive capsulitis by physiotherapists and provide us with new insights for improving the physiotherapists' policy in treating adhesive capsulitis patients, e.g., continuously increasing nociceptive impulse activity, as in early stages of adhesive capsulitis, could lead to peripheral and subsequently long-lasting central sensitization, as well as to an increased activity of the sympathetic nervous system. But up to now the involvement of central sensitization in adhesive capsulitis has not been studied yet and remains speculative. Finally, when selecting a physical treatment method for adhesive capsulitis, it is extremely important to consider the patient's symptoms, stage of the condition, and recognition of different patterns of motion loss. Guidelines for clinical assessment will be presented in this scoping review. © Clinical Rheumatology 2013. Source

Environment and Planning A

Between 1995 and 1999 the Flemish government succeeded in approving pieces of legisla- tion intended to counter the spatial developments that had characterised the preceding periods, namely suburbanisation and urban decay. It passed a law to combat vacancy and slum housing (1995), a law to invest in social urban renewal (1996), a housing law (1997), a new law on spatial planning (1999), and the first comprehensive spatial plan (1997). Unfortunately, recent information and an evaluation of the spatial planning effort reveal that these initiatives have not been successful. The suburbanisation of native Belgians did not stop: on the contrary, it is accelerating again. And the population growth in the cities is due to people coming from abroad (through family reunification or formation or as asylum seekers). In this contribution I investigate suburbanisation and deurbanisa- tion, asking why housing sprawl in Flanders is so persistent. I examine the structures behind sprawl, viewing them as the consequence of a longstanding dialectical process whereby physical artefacts interact with political choices and actions, cultural convictions, and economic possibilities that have reinforced each other in daily practice over and over again in one predominant direction. The basic argument is that Flanders' spatial planning and urban policies are locked into historical choices, making it difficult to implement new options successfully. © 2011 Pion Ltd and its Licensors.

IEEE Transactions on Power Electronics

The rotor position of a salient-pole permanent-magnet synchronous machine (PMSM) at standstill or rotating at low speed is often estimated by measuring the responses on high-frequency test signals. In some drives, the rotor position is computed by measuring important current ripples that are generated by supplying the PMSM periodically with high-frequency voltage test pulses. Besides these ripples, undesired distortions in the average-current samples have been measured. Simulation results have revealed that these distortions are caused by a test signal, as it produces a nonzero voltage deviation from the steady-state stator voltage. In this paper, a low-speed sensorless strategy is discussed where a strong reduction of the aforementioned distortions is obtained by adapting the test signals to the steady-state stator voltage. The main assumption is that an accurate estimation of the steady-state voltage is made by using the controller output. The computation of the adaptive test signals is done by taking into account the voltage restriction of the dc-bus voltage. Simulation results, as well as experimental measurements, indicate the effectiveness of the adaptive test signals in a sensorless controlled interior PMSM. © 2006 IEEE. Source

Crime, Law and Social Change

This article responds to the call for more empirical knowledge about transnational environmental crime. It does so by analysing the case of illegal transports of electronic waste (e-waste) in a European trade hub. Given the complexity and global nature of transnational environmental crime, it is difficult to determine which actors are involved. In this regard, a local research setting allows the actors involved in illegal transports of e-waste to be identified. This research tries to determine whether these actors and their roles can be considered legal or illegal and illustrates the legal-illegal interfaces in e-waste flows. Moreover, this case study analyses the push, pull and facilitating factors and therefore looks at what motivations and opportunities shape the flows of e-waste in locations of origin, transit and destination. The results show that the social organisation and emergence of transnational environmental crime is on a thin line between legal and illegal which needs to be contextualised within the global reality of the locations of origin, transit and destination. © 2012 Springer Science+Business Media B.V.
