The working hypothesis for this research project is that it is possible to develop a new functional polymer printing process for the direct application of conductive polymer onto textiles. We will use the basic extrusion technology that is currently applied in 3D printing. Thus the aim is also expanding the knowledge and knowhow base of 3D printing and make this technology applicable for deposition of functional polymers on textiles in such a way that process parameters are clearly understood, and pre-defined final product specifications can be met. Thus the challenge is to apply conductive tracks with a simple one step process that fits the current textile production processes. This means that investigating polymer deposition onto textiles of bio based polymers like PLA, doped with carbon could be a versatile route to achieving economic and sustainable conducting textiles. If the mechanism underlying the bonding of doped PLA with textiles can be controlled for processing then a new route to achieving conductive grids would be opened.Paper written by the Saxion chair Smart Functional Materials and The Unversity of Twente for and accepted by the Autex Conference 2013 (22-24 May 2013, Dresden, Germany).

Safety and Security (S&S) have the same goal, that is to maintain the integrity of human, infrastructure, hardware, software, capital and intangible assets of a system. However, literature and practice indicate that the relationship between S&S has not yet been clearly defined and their boundaries remain blurry. The current paper presents a short review of academic and professional literature about the relationship between S&S. This relationship is examined by looking at the S&S dependencies, their similarities and differences, and the role of the human element in achieving and maintaining the desired S&S levels. The review of literature showed that (1) there is a tendency to emphasize on the effects of security on safety and underestimate the opposite, (2) human factors are not part of security training to the extent are addressed in safety training, (3) security and safety problems can be the result of both internal and external disturbances and agents, (4) the intentionality or not of outcomes, and not of the action, can stand as a valid criterion to classify an event as a security or a safety one correspondingly, (5) S&S issues can result in negative implications internally and externally to the system, and (6) the synergy between S&S is of paramount importance for achieving the optimum levels of system protection. The positions of this paper might comprise a basis for enriching educational programmes around S&S and igniting relevant research.
BackgroundScientific software incorporates models that capture fundamental domain knowledge. This software is becoming increasingly more relevant as an instrument for food research. However, scientific software is currently hardly shared among and (re-)used by stakeholders in the food domain, which hampers effective dissemination of knowledge, i.e. knowledge transfer.Scope and approachThis paper reviews selected approaches, best practices, hurdles and limitations regarding knowledge transfer via software and the mathematical models embedded in it to provide points of reference for the food community.Key findings and conclusionsThe paper focusses on three aspects. Firstly, the publication of digital objects on the web, which offers valorisation software as a scientific asset. Secondly, building transferrable software as way to share knowledge through collaboration with experts and stakeholders. Thirdly, developing food engineers' modelling skills through the use of food models and software in education and training.
