Artikel 4:36 BW en werkzaamheden verricht voor een bv
In deze bijdrage gaat de auteur in op een aantal aspecten van artikel 4:36 BW. Dit wordt gedaan aan de hand van een arrest van het Gerechtshof Amsterdam dat gewezen is op 12 februari 2019. Daarin kwam de vraag aan de orde of ook recht op een som ineens bestaat indien werkzaamheden zijn verricht voor een bv waarin de erflater gerechtigd was. De auteur analyseert de toepasselijkheid van artikel 4:36 BW bij werk dat verricht is voor kapitaalvennootschappen of personenvennootschappen. Ook wordt stilgestaan bij de rol van de verrichte werkzaamheden en de wenselijkheid van de huidige regeling. De conclusie luidt dat onvoldoende grond bestaat voor onderscheid tussen werkzaamheden die zijn verricht voor een kapitaalvennootschap dan wel voor de erflater zelf. Besloten wordt daarom met een oproep om de wet op dit punt aan te passen.

What can Belgium and The Netherlands learn from each other about commercial mediation practice?
This article discusses the Belgian perspective on the Dutch ‘ZAM/ACB research on possibilities and impediments for commercial mediation’ which was undertaken by the Montaigne Centre of the University of Utrecht. In Belgium bMediation, the Federal Mediation Committee and the Ghent University periodically monitor the practice of mediation in Belgium with the instrument of the 'Bemiddelingsbarometer'. It turns out that parties and their advisers in both Belgium and the Netherlands still prefer a traditional judicial approach instead of mediation, mostly because of a lack of information.
Internationale parentale ontvoering en conflictde-escalatie in het belang van het kind

International parental abduction and conflict de-escalation in the best interests of the child
This research aims to contribute to the development of an adequate handling of the complex, conflictual family situation that occurs during a parental abduction. The following research question is answered: to what extent can the methods of conflict resolution – in the Belgian context – be optimized so that the interests of the child are guaranteed, in the light of the theoretical insights provided by Glasl’s conflict theory? Attention is paid to the limited effectiveness of legal procedures on the one hand and the mediation on the other. The method of de-escalation, developed by Glasl, offers a useful diagnostic tool for the conflict counsellor. In addition, the metaphor of the ladder he uses is extremely valuable as a tool for gaining insight into the mechanisms of conflict-escalation. A clear theoretical framework for the judiciary in the interpretation of an escalated conflict can lead to a better understanding of the possibilities and limits of cooperation between ex-partners, which benefits the best interests of the child.
A Novel Step-Up Power Converter Configuration for Solar Energy Application
Authors: Ghaderi Davood , Bayrak Gokay 
Published: June 2019

Renewable Energy Sources (RES) including full cells, wind turbines, and photovoltaic panels, widely are spreading. Among all the renewable energy sources, solar power generation system tops the list. The first choice is the boost converter when the voltage step-up is the issue. But the most important subject is applying an efficient structure with high gain, cheap and quick controller circuit. Our proposed cascaded boost converter is one of such converters which consists of several cheap components such as diode, inductor, capacitor and power switch, which has same switching frequency and phase shift in comparison with conventional boost converters. In comparison with the classic cascaded boost converter, the voltage gain for the proposed structure is very high and by forming a preamplifier layer, for a duty cycle of 80 % by adding only two diodes, one inductor, and one capacitor for the second block, voltage gain is increased by 5 times compared to the classic boost converter. The proposed method provides the increased output voltage along with the duty cycle. The projected strategy has been verified with the help of Matlab/Simulink. Also, a hardware implementation of the proposed converter has been done around 200 W by applying a Jiangyin HR-200W-24V type solar panel.
L’intervention éducative : problématique, enjeux et perspectives
Authors: Alaoui Driss , Pelletier Liliane , Lenoir Yves 
Published: June 2019

Ce texte fournit une introduction à l’intervention éducative, une notion aux origines « chargées », un terme qui n’est pas neutre et qui touche nécessairement à la définition du rôle et de la posture du chercheur en sciences humaines et sociales. L’intervention constitue à la fois une conception de la réalité, un rapport pluriel (à soi, à l’autre et au monde), une pratique complexe où le sujet et l’objet sont entremêlés, entrelacés et dialectisés tout au long de l’interaction qui les lie. Plusieurs auteurs (Lenoir, Larose, Deaudelin, Kalubi et Roy, 2002 ; Couturier, 2004 ; Larose, Couturier, Bédard, Larivée, Boulanger, Terrisse, 2013 ; Lenoir, 2009, 2011, 2014 ; Lenoir, Rey et Fazenda, 2001 ; etc.) ont souligné son caractère polysémique, sinon polyphonique, qui est présenté brièvement dans cette introduction. En éducation et en formation, la dialectique entre enseignement et apprentissage suppose interactions et médiations, introduit des régulations, éclaire le caractère dynamique du processus décisionnel des enseignants, produit du changement, autant de pistes qui permettent d’envisager la question de l’intervention en éducation selon trois perspectives : notionnel, épistémologique et empirique/praxique. Les problématiques qui sont développées dans les six articles du numéro thématique sont ici présentées avec pour ambition commune d’examiner des processus d’enseignement-apprentissage et de mettre en débat le concept d’intervention par le biais d’une démarche critique.

Published: June 2019

La puesta en marcha de los grados y postgrados en las universidades españolas ha venido acompañada de una revisión de las metodologías docentes utilizadas y la incorporación en muchos casos de Tecnologías de la Información y la Comunicación (TIC). Tecnologías como las Herramientas de Respuesta de Audiencia (HRA), los Clickers, y los vídeos (mUVies) se utilizaron en una asignatura cuantitativa de un grado ofertado por la Universitat de València (UV), en un intento de paliar la baja carga lectiva de la misma y dotar al alumnado de material de apoyo dentro y fuera del aula. El trabajo que se presenta examina la percepción que el alumnado tuvo del uso de dichas TIC en su proceso de aprendizaje y también el volumen de trabajo que supuso su puesta en marcha. Utilizando análisis descriptivos e inferenciales sobre las opiniones obtenidas en las encuestas acerca de las TIC y los resultados de la evaluación continua y el examen final, concluimos que el alumnado valoró muy positivamente el uso de ambas TIC con una calificación media superior a 8 (sobre 10), valorando mejor los mUVies que los Clickers. En cuanto al volumen de trabajo que la implantación de las TIC supuso, esta se estima en unas 7.5 horas para el alumnado y de unas 132.5 horas para el profesorado.
Optical microscopic study of surface morphology and filtering efficiency of face masks
Authors: Neupane Bhanu Bhakta , Mainali Sangita , Sharma Amita , Giri Basant 
Published: June 2019

BackgroundLow-cost face masks made from different cloth materials are very common in developing countries. The cloth masks (CM) are usually double layered with stretchable ear loops. It is common practice to use such masks for months after multiple washing and drying cycles. If a CM is used for long time, the ear loops become stretched. The loop needs to be knotted to make the mask loop fit better on the face. It is not clear how washing and drying and stretching practices change the quality of a CM. The particulate matter (PM) filtering efficiency of a mask depends on multiple parameters, such as pore size, shape, clearance, and pore number density. It is important to understand the effect of these parameters on the filtering efficiency.MethodsWe characterized the surface of twenty different types of CMs using optical image analysis method. The filtering efficiency of selected cloth face masks was measured using the particle counting method. We also studied the effects of washing and drying and stretching on the quality of a mask.ResultsThe pore size of masks ranged from 80 to 500 μm, which was much bigger than particular matter having diameter of 2.5 μm or less (PM2.5) and 10 μm or less (PM10) size. The PM10filtering efficiency of four of the selected masks ranged from 63% to 84%. The poor filtering efficiency may have arisen from larger and open pores present in the masks. Interestingly, we found that efficiency dropped by 20% after the 4th washing and drying cycle. We observed a change in pore size and shape and a decrease in microfibers within the pores after washing. Stretching of CM surface also altered the pore size and potentially decreased the filtering efficiency. As compared to CMs, the less frequently used surgical/paper masks had complicated networks of fibers and much smaller pores in multiple layers in comparison to CMs, and therefore had better filtering efficiency. This study showed that the filtering efficiency of cloth face masks were relatively lower, and washing and drying practices deteriorated the efficiency. We believe that the findings of this study will be very helpful for increasing public awareness and help governmental agencies to make proper guidelines and policies for use of face mask.

User authentication is one of the most significant issues in the field of Information Security. The most common and convenient authentication method used is the alphanumeric password which has significant drawbacks. To overcome the vulnerabilities of traditional methods, graphical password schemes have been developed as possible alternative solutions to text-based scheme. A potential drawback of graphical password schemes is that they are more vulnerable to shoulder surfing than conventional alphanumeric text passwords due to their visual interface. To overcome the shortcoming of existing graphical password schemes this project focuses on developing a graphical authentication system that is resistant to shoulder surfing attack.
Working memory of highly self‐critical men is impaired by failure
Authors: Lueke Niloufar , Rubinow David 
Published: June 2019

SummaryPrevious studies have shown self‐criticism to be negatively associated with goal progress. In order to investigate factors that may influence this association, the present study examined the interactive impact of performance (failure vs. success) and self‐criticism on working memory (WM). Goal‐directed behavior in the achievement domain was operationalized as comparative performance on two strongly correlated WM span tasks. The effect of negative or positive performance feedback was assessed by presenting a success or a failure experience between the two WM span tasks in order to examine the influence of failure and success on the second WM span task compared with the first/baseline. A male‐only sample was used as a follow‐up to a previous study that has utilized a female‐only sample. Findings revealed self‐criticism to serve as an individual difference factor that influences men's WM functioning in the context of failure. This interactive effect may contribute to diminished goal progress in men.

Published: June 2019

AbstractThere is an increasing demand for specialized pressure sensors in various applications. Previously, capacitive pressure sensors have been shown to have wide versatility in use, with a high degree of potential tuning possible through manipulating the geometry or material selection of the dielectric layer. However, in order to make sensors that are tunable and predictable, the design and fabrication method first needs to be developed. Presented here is an improved fabrication method to achieve tunable, consistent, and reproducible pressure sensors by using a pyramid microstructured dielectric layer along with a lamination layer. The as‐produced sensor performance is able to match predicted trends. Further, a simple model based on this system is developed and its efficacy is experimentally confirmed. Then, the model to predict a wide range of material and microstructure geometric properties prior to device fabrication is used to provide trends on sensor performance. Finally, it is demonstrated that the new method can be used to targetedly design a pressure sensor for a specific application—in vitro pulse sensing.
A Li2S‐TiS2‐Electrolyte Composite for Stable Li2S‐Based Lithium–Sulfur Batteries
Authors: Chung Sheng‐Heng , Manthiram Arumugam 
Published: June 2019

AbstractLi2S is a fully lithiated sulfur‐based cathode with a high theoretical capacity of 1166 mAh g−1 that can be coupled with lithium‐free anodes to develop high‐energy‐density lithium–sulfur batteries. Although various approaches have been pursued to obtain a high‐performance Li2S cathode, there are still formidable challenges with it (e.g., low conductivity, high overpotential, and irreversible polysulfide diffusion) and associated fabrication processes (e.g., insufficient Li2S, excess electrolyte, and low reversible capacity), which have prevented the realization of high electrochemical utilization and stability. Here, a new cathode design composed of a homogeneous Li2S‐TiS2‐electrolyte composite that is prepared by a simple two‐step dry/wet‐mixing process is demonstrated, allowing the liquid electrolyte to wet the powder mixture consisting of insulating Li2S and conductive TiS2. The close‐contact, three‐phase boundary of this system improves the Li2S‐activation efficiency and provides fast redox‐reaction kinetics, enabling the Li2S‐TiS2‐electrolyte cathode to attain stable cyclability at C/7 to C/3 rates, superior long‐term cyclability over 500 cycles, and promising high‐rate performance up to 1C rate. More importantly, this improved performance results from a cell design attaining a high Li2S loading of 6 mg cm−2, a high Li2S content of 75 wt%, and a low electrolyte/Li2S ratio of 6.
Facile synthesis of sterically demanding SHOP‐type nickel catalysts for ethylene polymerization

Published: June 2019

The P,O‐chelated shell higher olefin process (SHOP) type nickel complexes are practical homogeneous catalysts for the industrial preparation of linear low‐carbon α‐olefins from ethylene. We describes that a facile synthetic route enables the modulation of steric hindrance and electronic nature of SHOP‐type nickel complexes. A series of sterically bulky SHOP‐type nickel complexes with variable electronic nature, {[4‐R‐C6H4C(O) = C‐PArPh]NiPh (PPh3); Ar = 2‐[2′,6′‐(OMe)2C6H3]C6H4; R = H (Ni1); R = OMe (Ni2); R = CF3 (Ni3)}, were prepared and used as single component catalysts toward ethylene polymerization without using any phosphine scavenger. These nickel catalysts exhibit high thermal stability during ethylene polymerization and result in highly crystalline linear α‐olefinic solid polymer. The catalytic performance of the SHOP‐type nickel complexes was significantly improved by introducing a bulky ortho‐biphenyl group on the phosphorous atom or an electron‐withdrawing trifluoromethyl on the backbone of the ligand, indicating steric and electronic effects play critical roles in SHOP‐type nickel complexes catalyzed ethylene polymerization.
Development of Pelvic Incidence and Lumbar Lordosis in Children and Adolescents

Published: June 2019

ABSTRACTPelvic incidence (PI) is a measure of the sagittal orientation of the sacrum relative to the acetabula and is not dependent on posture. In asymptomatic adults, PI correlates with lumbar lordosis. Lumbar lordosis is shown to increase with age following the onset of unassisted bipedal locomotion in children, but to what extent PI changes in relation to lumbar lordosis during skeletal maturation is unclear. The purpose of this study is to understand how PI, lumbar lordosis, and age are related in children and adolescents. PI, supine lumbar lordosis (SLL), and individual wedging angles of the lumbar vertebral bodies were measured on mid‐sagittal reformatted images from 144 abdominal computed tomographic scans of individuals aged 2–20 years old, divided into three separate age categories representing pre‐growth spurt (ages 2–9), growth spurt (10–15), and post‐growth spurt (16–20). Our results showed that, while SLL significantly increased with age during development, PI did not. Despite the fact that PI hardly changed with age, the difference between PI and SLL decreased nonlinearly with age. SLL did not correlate with PI in the youngest age category, but positively correlated with PI in the middle and oldest age categories. The relationship between lumbar lordosis and PI, which is correlated in adults, was significant in our older age categories and not in our youngest age category. Our results indicate that PI in children and adolescents may have some predictive value for adult lumbar lordosis. Anat Rec, 302:2132–2139, 2019. © 2019 American Association for Anatomy
Kinetics of anaerobic methane oxidation coupled to denitrification in the membrane biofilm reactor

Published: June 2019

AbstractAnaerobic oxidation of methane coupled to denitrification (AOM‐D) in a membrane biofilm reactor (MBfR), a platform used for efficiently coupling gas delivery and biofilm development, has attracted attention in recent years due to the low cost and high availability of methane. However, experimental studies have shown that the nitrate‐removal flux in the CH4‐based MBfR (<1.0 g N/m2‐day) is about one order of magnitude smaller than that in the H2‐based MBfR (1.1–6.7 g N/m2‐day). A one‐dimensional multispecies biofilm model predicts that the nitrate‐removal flux in the CH4‐based MBfR is limited to <1.7 g N/m2‐day, consistent with the experimental studies reported in the literature. The model also determines the two major limiting factors for the nitrate‐removal flux: The methane half‐maximum‐rate concentration (K2) and the specific maximum methane utilization rate of the AOM‐D syntrophic consortium (kmax2), with kmax2 being more important. Model simulations show that increasing kmax2 to >3 g chemical oxygen demand (COD)/g cell‐day (from its current 1.8 g COD/g cell‐day) and developing a new membrane with doubled methane‐delivery capacity (Dm) could bring the nitrate‐removal flux to ≥4.0 g N/m2‐day, which is close to the nitrate‐removal flux for the H2‐based MBfR. Further increase of the maximum nitrate‐removal flux can be achieved when Dm and kmax2 increase together.

AbstractThe exact recipe to prepare the ancient Maya Blue (MB), an incredibly resistant and brilliant pigment prepared from indigo (dye) and Palygorskite (clay), is lost to the ages. To unravel the key features of the MB formation process, several inorganic‐dye couples were heated to 200 °C and cooled to RT, to investigate their reactivity and the diffusion and degree of sequestration of the dye into the inorganic host. In situ XRPD/PDF and fiber optic reflectance spectroscopy (FORS) data, along with TGA, provided a comprehensive overview on MB formation mechanism. XRPD/PDF gave information on long/short range behaviors of water desorption/adsorption and indigo sequestration, while TGA and in situ FORS gave information on mass and optical changes within temperature. Ex situ dye removal was used to understand the sample stability after the thermal treatment. A statistical approach based on principal component analysis was exploited to efficiently and jointly analyze the ≈3000 collected patterns. MB formation starts below 110 °C with disordered distribution of indigo within the channels, reaching maximum reaction speed and higher ordering at 150 °C. Above 175 °C, color changes and a stronger sequestration of indigo into framework channels are observed, whereas the affinity for water is dramatically reduced. The origin of different colors, hues, and stability in historical MB samples can then be explained in terms of different thermal histories of the starting mechanical indigo/palygorskite mixtures.

Published: June 2019

AbstractThe practical application of advanced personalized electronics is inseparable from flexible, durable, and even self‐healable energy storage devices. However, the mechanical and self‐healing performance of supercapacitors is still limited at present. Herein, highly transparent, stretchable, and self‐healable poly(2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid) (PAMPSA)/poly(vinyl alcohol) (PVA)/LiCl polyelectrolytes were facilely prepared by one‐step radical polymerization. The cooperation of PAMPSA and PVA significantly increased the mechanical and self‐healing capacity of the polyelectrolyte, which exhibited superior stretchability of 938 %, stress of 112.68 kPa, good electrical performance (ionic conductivity up to 20.6 mS cm−1), and high healing efficiency of 92.68 % after 24 h. After assembly with polypyrrole‐coated single‐walled carbon nanotubes, the resulting as‐prepared supercapacitor had excellent electrochemical properties with high areal capacitance of 297 mF cm−2 at 0.5 mA cm−2 and good rate capability (218 mF cm−2 at 5 mA cm−2). Besides, after cutting in two the supercapacitor recovered 99.2 % of its original specific capacitance after healing for 24 h at room temperature. The results also showed negligible change in the interior contact resistance of the supercapacitor after ten cutting/healing cycles. The present work provides a possible solution for the development of smart and durable energy storage devices with low cost for next‐generation intelligent electronics.
