While using Li4Ti5O12 as the anode material in lithium ion batteries greatly enhances their operation safety and avoids the formation of a solid electrolyte interface, the synthesis of this material often comes at a high time and energy cost. A typical solid-state synthesis method requires the reagents to be kept at temperatures up to 900 °C for several hours. Both synthesis temperature and processing time were reduced by applying the concept of solution combustion synthesis, where a sol-gel precursor is synthesized which generates the energy needed for complete sample conversion and crystallization by itself when it is heated to a...

Microwire arrays are a powerful tool for the exertion of localized thermal stress on cellular networks. Combining microwire arrays with a set of orthogonal axon-guiding microchannels on-chip allows positioning of neurites as well as control over their polarity. In this paper, we present a new fabrication approach, based on standard clean roomfabrication and sacrificial layer etching for the integration ofmicrowire arrays into neurite guiding structures.The system permits the application of strong temperature gradients enabling localized thermal stimulation inside microchannels.

Potential-induced degradation (PID) of photovoltaic (PV) modules gets a lot of attention since 2010 when Solon published their findings about a degradation mechanism in their PV modules caused by high potential differences between the solar cell and the grounded frame. Module level efficiency drops of 30% and more caused by PID have been reported. A stress test for PID according to IEC 62804 and a recovery test in the same conditions were conducted on a set of 49 commercially available PV modules. In this paper we report the irreversibility of highly affected (i.e. over 85% PID) PV modules. From this...
Cardiopulmonary resuscitation (CPR) is the act of giving chest compressions, rescue breathings and early defibrillation in cardiac arrest (CA) patients. The main goal of CPR is to preserve the pre-arrest neurological state by maintaining sufficient cerebral blood flow and oxygenation and consequently achieving return of spontaneous circulation (ROSC). During pre-hospital CPR, monitoring
possibilities are limited and do not give information about the brain. Cerebral oxygen saturation (rSO2) measured via near infrared spectroscopy (NIRS) technology is non-invasive, provides continuous information about the oxygenation of the brain and moreover is independent of a pulsatile signal. Therefore, this might be the ideal monitoring parameter...

AIM This study aimed to systematically map the severity of mirror movements in both hands in a prospective cohort of children with unilateral cerebral palsy, and to explore the relationship with hand function and brain lesion type.
METHOD Seventy-eight children were included (41 males, 37 females; age 9y 4mo, SD 3y 1mo, range 5–15y). Mirror movements were scored during three repetitive tasks following Woods and Teuber criteria. Strength, tone, Melbourne Assessment, Jebsen–Taylor test, and
Assisting Hand Assessment were evaluated. Lesions were classified into malformations (n=5), periventricular (n=43), cortico–subcortical (n=22), and postnatally acquired lesions (n=8).
RESULTS Significantly more mirror movements were observed in the...
It is commonplace in European constitutional practice and theory to use the terms ‘national identity’ and ‘constitutional identity’ interchangeably. On the one hand, several Advocates General to the European Court of Justice have employed the concept of ‘constitutional identity’ to delineate what is protected under Article 4(2) TEU, even though, strictly speaking that Treaty provision refers to the Member States’ national identities, inherent in their fundamental structures. On the other hand, certain domestic constitutional courts which present themselves
as the ultimate defenders of the identity of their constitution have pointed to Article 4(2) TEU to legitimate their assumed power to review...

Het Nagoya-protocol van 2010 over de toegang tot genetische rijkdommen en de eerlijke en billijke verdeling van voordelen voortvloeiende uit hun gebruik evenals de daarmee samenhangende Europese Verordening 511/2014 geven een antwoord op de vraag hoe toegang tot genetische rijkdommen gegarandeerd kan worden. Zowel de Europese Unie zelf als verschillende Europese lidstaten worstelen echter met de implementatie van het protocol (en de verordening).
Dat geldt zeker ook voor België/Vlaanderen. Deze bijdrage analyseert de moeilijkheden op Europees en nationaal niveau (in België/ Vlaanderen en vier andere lidstaten) met de uitvoering van de verplichtingen van het Nagoyaprotocol. Ze concludeert dat, hoewel het Nagoya-protocol...

For better management of parking a good balance between the supply and demand is required. This can be achieved by using a tool that can support the development of efficient parking policies. The
basis of the current research is to optimize the use of PARKAGENT, an agent based geosimulation model, used for simulating parking search in a city. It serves as tool for the analysis of parking policy by helping decision-makers to explore policy alternatives and identifying their impacts on drivers, residents, and the resources of the city. The current study mainly focuses on two developments: (i) Exploring the sensitivity of...

We report an electron momentum spectroscopy study of vibrational effects on the electron momentum distributions of the outer valence orbitals of adamantane (C10H16). The symmetric noncoplanar (e, 2e) experiment has been carried out at an incident electron energy of 1.2 keV. Furthermore, theoretical calculations of the electron momentum distributions with vibrational effects being involved have been performed using the harmonic analytical quantum mechanical and Born-Oppenheimer molecular dynamics approaches. In spite of the complex nature of the vibrational structure of this large molecule, both approaches provide overall quantitative insights into the results of the experiment. Comparisons between experiment and theory have...

Over de plaats van het voorzichtigheidsbeginsel binnen het Conceptual Framework (CF) is, in het kader van de voorstellen tot wijziging van het CF, veel discussie geweest, met name vanuit de EU, en dit vanwege de wens om een zeker ‘conservatisme’ in financiële overzichten te behouden. In deze bijdrage wordt ingegaan op het concept ‘accounting conservatisme’ en wordt aandacht besteed aan de belangrijkste elementen binnen het CF die bijdragen aan conservatisme in financiële overzichten. Naast een behandeling van het voorzichtigheidsbeginsel wordt er vooral aandacht besteed aan de definitie van activa als bron van conservatisme.

Rheumatoid arthritis (RA) is the world’s most common autoimmune disease mainly characterized by a chronic inflammation of multiple synovial joints. Rheumatologists now have a whole range of treatment options including glucocorticoids (GCs), classical synthetic and biological disease-modifying antirheumatic drugs (cs- and bDMARDS), resulting in a tremendous improvement in treatment outcomes for RA patients over the last two decades. Despite this progress, the choice of treatment regimen to achieve stable remission at the individual patient level still largely depends on trial and error. In this review, the need for novel theranostic markers that can predict a patient’s response to methotrexate, the...

The blood-brain barrier (BBB) is indispensable for the maintenance of brain homeostasis and proper neuronal functioning. Dysfunction of the BBB significantly contributes to the pathogenesis of neuroinflammatory and neurodegenerative diseases like stroke, multiple sclerosis (MS), and Alzheimer's disease (AD). The neuroinflammatory environment that characterizes these disorders propagates chronic impaired function of the BBB, processes that will be discussed in this review. Limiting dysfunction of the BBB may be an attractive target for treatment of neurological disorders. To date, no current treatments are directly targeting the function of the BBB. In this review, we will specifically discuss the potential protective role...

Most existing traffic conflict indicators do not sufficiently take into account the severity of the injuries resulting from a collision had it occurred. Thus far, most of the indicators that have been developed express the severity of a traffic encounter as their proximity to a collision in terms of time or space, This paper presents the theoretical framework and the first implementation of Extended Delta-V as a measure of traffic conflict severity in site-based observations. It is derived from the concept of Delta-V as it is applied in crash reconstructions, which refers to the change of velocity experienced by a...
