Seaweeds from the genus Porphyra play a big economic role in seaweed aquaculture, mainly in Asia. In Europe, resources are put towards seaweed cultivation, but without attention to the Porphyra species which is also native to Europe. Different nomenclature and specifications are used to describe Porphyra, due to taxonomical reclassification and difficult phenotypical identification. Abiotic & biotic together with seasonal factors make for major variance in chemical compositions that are reported. This is also fueled by differences in chemical analytical methods and procedures followed. Combining taxonomical challenges, variance due to seasonal factors and differences in analysis, overviewing published research on Porphyra constituents such as protein, polysaccharides and fatty acids is warranted. Within this review, cellular consitutents found in Porphyra are discussed, including proteins, polysaccharides, fatty acids and mycosporine-like amino acids (MAA’s). MAA's are considered amongst the strongest UV-photoprotectants found in nature and feature possible applications in cosmetics. As global interest in seaweeds as food, feed and industrial resource is emerging, opportunities for Porphyra constituents is rising.

Presented at the 11th International Conference on ICT in Education, Research and Industrial Applications: Integration, Harmonization and Knowledge Transfer Lviv, Ukraine, May 14-16, 2015. Author supplied: Abstract. User requirements and low-cost small quantity production are new challenges for the modern manufacturing industry. This means that small batch sizes or even the manufacturing of one single product should be affordable. To make such a system cost-effective it should be capable to use the available production resources for many different products in parallel. This paper gives a description of the requirements and architecture of an end-user driven production system. The end-user communicates with the production system by a web interface, so this manufacturing system can be characterized in terms of cloud comput- ing as the implementation of manufacturing as a service, abbreviated to MaaS.

Author supplied: Abstract—The growing importance and impact of new technologies are changing many industries. This effect is especially noticeable in the manufacturing industry. This paper explores a practical implementation of a hybrid architecture for the newest generation of manufacturing systems. The papers starts with a proposition that envisions reconfigurable systems that work together autonomously to create Manufacturing as a Service (MaaS). It introduces a number of problems in this area and shows the requirements for an architecture that can be the main research platform to solve a number of these problems, including the need for safe and flexible system behaviour and the ability to reconfigure with limited interference to other systems within the manufacturing environment. The paper highlights the infrastructure and architecture itself that can support the requirements to solve the mentioned problems in the future. A concept system named Grid Manufacturing is then introduced that shows both the hardware and software systems to handle the challenges. The paper then moves towards the design of the architecture and introduces all systems involved, including the specific hardware platforms that will be controlled by the software platform called REXOS (Reconfigurable EQuipletS Operating System). The design choices are provided that show why it has become a hybrid platform that uses Java Agent Development Framework (JADE) and Robot Operating System (ROS). Finally, to validate REXOS, the performance is measured and discussed, which shows that REXOS can be used as a practical basis for more specific research for robust autonomous reconfigurable systems and application in industry 4.0. This paper shows practical examples of how to successfully combine several technologies that are meant to lead to a faster adoption and a better business case for autonomous and reconfigurable systems in industry.

In this paper, the authors explore the possible contribution of serious games for advanced academic and/or professional learning in particular to support the decision-making andmanagement of complex infrastructures, such as utilities, ports and wind farms. The developments of the computer industry make it more attractive to add computer technology into simulation games to make the results of the game more realistic and so achieve more learning with the participants. In the future this will be more important to make the games still attractive for the players, because they are grown up with computers, e-learning and online communication. An example of a case study of SIM Maas, a simulation game about the development of the Port of Rotterdam (PoR), will be given. This case illustrates the use of computer-based simulation-games for professional learning.

In a study commissioned by the Association of Dutch Municipalities (VNG), the applied research group European Impact has compiled the results from interviews executed by approximately 240 European Studies students at The Hague University of Applied Sciences. The purpose of this report is to compare and contrast the situation of intra-EU labor migrants (hereafter referred to as EU mobile citizens) in regard to registration, housing, and information flows in 12 different municipalities across the EU. Based on semi-structured interviews with municipal workers and individuals from employment agencies/companies from the selected municipalities, the picture that emerges is one of divergence. There are significant variations regarding the registration procedure and information flows for EU mobile citizens across the selected municipalities. For registration, differences include where the registration takes place, the amount of collaboration between municipalities and employment agencies/companies on registering EU mobile citizens, and the importance of addresses in the registration process. Regarding information flows across the selected municipalities, there are significant variations in the amount and type of information available to EU mobile citizens, the number of languages information is available in,as well as how the information is organized (i.e. in a centralized or decentralized way). Furthermore, while all the member states in which the selected municipalities are located provide information regarding registration on the Single Digital Gateway, not all provide information about renting housing. As for housing, the results revealed that most of the selected municipalities face issues with housing and that EU mobile citizens typically find housing either via their employers or personal network. Based on the results, a list of potential best practices and policy areas that could be improved was compiled. Furthermore, in order to have a stronger overview of policy developments in the field of EU mobile citizens among different municipalities, the VNG could consider hosting a Community of Practice with different municipalities across the EU as well as monitoring Interreg Europe projects focused on improving the situation of EU mobile citizens.

Over recent years aspects of sustainability have claimed a central role in many countries. As a result research for sustainability has become an important driver for innovation. This paper describes developing a model that supports SMEs in integrating sustainability in their business and innovation processes. In general innovation and entrepreneurship are important in the realm of national economies because they hold the key to the continuity and growth of companies and economic growth within a country. National governments are spending vast sums of money to enable and improve innovation management and entrepreneurial behaviour within organizations. This is also the case in The Netherlands. Partnerships involving universities (education), companies (preferably SMEs) and industrial associations (business) and representatives from governmental organizations (community) are stimulated and should be geared towards: the development of sustainable networks, a contribution to regional economic growth within sectors, the development of learning communities in which best practices are shared, knowledge circulates and knowledge is created through applied research and last but not least sustainable relations are developed between universities and the business community. Within the centre for innovation and entrepreneurship at our university we have taken the initiative to develop an innovation programme for entrepreneurs in the construction industry to help them integrate sustainability in their business processes, while simultaneously professionalizing students and teachers. Sustainability and concern for the environment are two of the main reasons for entrepreneurs to look for opportunities to innovate. Policy measures are aimed at reduction of CO2 emission, waste management and alternative use of energy sources and materials. In line with these measures companies are urged to integrate sustainability in their business processes and search for innovative sustainable solutions. This paper describes the experiences with a number of SMEs in the construction industry and the barriers entrepreneurs encounter on the road towards sustainability. We focus on the role of the entrepreneur in the process of sustainable innovation and development. We conducted exploratory research and through an organisational analysis and in-depth interviews with the owners/managers of the companies insight was gained in innovation processes towards sustainable development. Conclusions show that one of the main bottlenecks is the dilemma posed by the need for profit for the continuity of a company, while taking into account people and planet. The dilemmas of innovation are described as issues that need to be addressed and which influence the innovative capacity of companies and organizations. This paper deals with the underlying factors related to the dilemma between sustainability and growth/profit.
