Irene Maldini’s PhD research discusses the quantity of clothing produced and consumed, its growth, and the environmental challenges associated with it. Moreover, Maldini examines how the field of design has reacted to this issue, reflecting critically on the gap between the expected and the actual effects of design strategies aimed at reducing clothing demand. Clothing personalization and durability have been central strategies to that end; however, this research points out that their expected effects are based on partial historical views and simplistic perspectives of clothing consumption. Therefore, the study proceeds in offering an alternative perspective on clothing consumption building on the systemic nature of the wardrobe.

How can we make Inquiry-Based Science and Mathematics Education (IBSME) durable? …. by incorporating it in the pre-service programs for elementary teachers! With pre-service students the training can be much more intensive than with inservice teachers. To have an impact in the classroom the minimum contact time in IBSME in-service and coaching has to be more than 90 hours (Supovitz & Turner, 2000). That number is hard to achieve in in-service but it is quite possible in preservice teacher education. From 9 – 11 January 2013 the Hogeschool van Amsterdam (HvA) hosted a field-visit sponsored by the EU Fibonacci project with a focus on pre-service teacher education. HvA developed two programs to strengthen IBSME in pre-service. One is an elective minor (30 ECTS) Science and Technology Education in the regularelementary teacher education program. The other is a pre-service program for academically talented students jointly developed by the University of Amsterdam and the Hogeschool of Amsterdam with inquiry as a major emphasis. The two programs are described in chapters 1 & 3 in this booklet. If you are still wondering what IBSE is, then read chapter 2 of Ana Blagotinsek of the University of Slovenia. She describes a neat example of an IBSE process with students in elementary teacher education. How do you start with a real worldquestion and initially little knowledge, and how do you investigate the question and eventually generate the knowledge needed to answer it? During the field-visit each participant presented one particularly successful approach in teacher training, for example, training teachers by ‘model teaching’ activities with these teachers’ own pupils. This method was used in different ways by 4 participants in different countries. They describe this in chapters 4 – 7. In chapter 8 colleague Frans Van Mulken describes the development of a lessonseries on graphs, rate of change, and speed using inquiry strategies inspired by the late mathematician and mathematics educator Hans Freudenthal. He also describes how pre-service students could be trained to teach the lesson series as inquiry. Simultaneously with this booklet, a Dutch booklet is published with overlapping contents but focused more on the Dutch context.
In het kader van actualisering van voorlichtingspublicaties (een samenwerkingsverband tussen FDP, FME, NIL, NIMR, Syntens en TNO Industrie & Techniek), is deze voorlichtingspublicatie aangepast aan de huidige stand der techniek. De originele publicatie is in 1992 tot stand gekomen door samenwerking van de Vereniging FME/CWM en het Nederlands Instituut voor Lastechniek in het kader van het FME/NIL project "Het lijmen als verbindingstechniek".
A feeling of worry, anxiety, loneliness and anticipation are commonplace in both medical and non-medical arenas such as elderly care. An innovative solution such as the ‘simple and effective’ comfyhand would offer better patient care and improved care efficiency with a high chance of long-term, economic efficiency. ComfyHand is a start-up in the healthcare sector that aims to develop sustainable products to improve patient wellbeing in healthcare settings. It does this by emulating the experience of holding a hand which gives the person comfort and support in moments where real human contact is not possible. Right now the comfyhand is in the development phase, working on several prototypes for test trials in elderly care and hospitals. In this project we want to explore the use of 3D printing for producing a comfyhand. Desired properties for the prototype include optimal heat transfer, softness, regulation of sweat, durability and sustainability. The goal of this study is to develop a prototype to test in a trial with patients within Envida, a care centre. The trial itself is out of scope of this project. This proposal focuses on researching the material of choice and the processability. Building on knowledge gained in a previous Kiem GoChem project and a Use Case (Shape3Dup) of a currently running Raak MKB project (Enlighten) on 3D printing of breast prostheses, several materials, designs and printing parameters will be tested.
Structural colour (SC) is created by light interacting with regular nanostructures in angle-dependent ways resulting in vivid hues. This form of intense colouration offers commercial and industrial benefits over dyes and other pigments. Advantages include durability, efficient use of light, anti-fade properties and the potential to be created from low cost materials (e.g. cellulose fibres). SC is widely found in nature, examples include butterflies, squid, beetles, plants and even bacteria. Flavobacterium IR1 is a Gram-negative, gliding bacterium isolated from Rotterdam harbour. IR1 is able to rapidly self-assemble into a 2D photonic crystal (a form of SC) on hydrated surfaces. Colonies of IR1 are able to display intense, angle-dependent colours when illuminated with white light. The process of assembly from a disordered structure to intense hues, that reflect the ordering of the cells, is possible within 10-20 minutes. This bacterium can be stored long-term by freeze drying and then rapidly activated by hydration. We see these properties as suiting a cellular reporter system quite distinct from those on the market, SC is intended to be “the new Green Fluorescent Protein”. The ability to understand the genomics and genetics of SC is the unique selling point to be exploited in product development. We propose exploiting SC in IR1 to create microbial biosensors to detect, in the first instance, volatile compounds that are damaging to health and the environment over the long term. Examples include petroleum or plastic derivatives that cause cancer, birth defects and allergies, indicate explosives or other insidious hazards. Hoekmine, working with staff and students within the Hogeschool Utrecht and iLab, has developed the tools to do these tasks. We intend to create a freeze-dried disposable product (disposables) that, when rehydrated, allow IR1 strains to sense and report multiple hazardous vapours alerting industries and individuals to threats. The data, visible as brightly coloured patches of bacteria, will be captured and quantified by mobile phone creating a system that can be used in any location by any user without prior training. Access to advice, assay results and other information will be via a custom designed APP. This work will be performed in parallel with the creation of a business plan and market/IP investigation to prepare the ground for seed investment. The vision is to make a widely usable series of tests to allow robust environmental monitoring for all to improve the quality of life. In the future, this technology will be applied to other areas of diagnostics.
Fontys University of Applied Science’s Institute of Engineering, and the Dutch Institute for Fundamental Energy Research (DIFFER) are proposing to set up a professorship to develop novel sensors for fusion reactors. Sensors are a critical component to control and optimise the unstable plasma of Tokamak reactors. However, sensor systems are particularly challenging in fusion-plasma facing components, such as the divertor. The extreme conditions make it impossible to directly incorporate sensors. Furthermore, in advanced reactor concepts, such as DEMO, access to the plasma via ports will be extremely limited. Therefore, indirect or non-contact sensing modalities must be employed. The research group Distributed Sensor Systems (DSS) will develop microwave sensor systems for characterising the plasma in a tokamak’s divertor. DSS will take advantage of recent rapid developments in high frequency integrated circuits, found, for instance, in automotive radar systems, to develop digital reflectometers. Access through the divertor wall will be achieved via surface waveguide structures. The waveguide will be printed using 3D tungsten printing that has improved precision, and reduced roughness. These components will be tested for durability at DIFFER facilities. The performance of the microwave reflectometer, including waveguides, will be tested by using it to analyse the geometry and dynamics of the Magnum PSI plasma beam. The development of sensor-based systems is an important aspect in the integrated research and education program in Electrical Engineering, where DSS is based. The sensing requirements from DIFFER offers an interesting and highly relevant research theme to DSS and exciting projects for engineering students. Hence, this collaboration will strengthen both institutes and the educational offerings at the institute of engineering. Furthermore millimeter wave (mmWave) sensors have a wide range of potential applications, from plasma characterisation (as in this proposal) though to waste separation. Our research will be a step towards realising these broader application areas.
