With the increase in large-scale cruise tourism worldwide, researchers have highlighted the inauthenticity of the cruise experience and the reconstruction of space. This research deals with new aspects: fast tourism through time-space compression, and the formation of enclosed, customized ‘tourist bubbles’ that confine the tourists and promote a constructed authenticity of the experience on-shore. The second aim is to advance applied research in slower cruise excursions, especially in emerging cruise destinations. The research is based on extensive field work conducted during nine cruise-excursions to the sand desert and an oasis in the Sultanate of Oman. Oman is in the early stages of developing mega-cruise tourism while having received little attention in tourism research. For this study, in-depth interviews were conducted with German-speaking cruise tourists, cruise employees as well as with local cultural brokers and the Minister of Tourism. Moreover, participant observation, travel ethnography and photography were applied. Results indicate while moving from one customized ‘tourist bubble’ to the next one, time is controlled and enhanced through fast modes of transportation and a tight schedule of the excursion. The tourists and their cultural brokers are ‘contained’ in time and space, while some are struggling for more authentic experiences. They are shielded off from the local environment, ‘grazing’ destinations within a short time.

In recent years, the number of human-induced earthquakes in Groningen, a large gas field in the north of the Netherlands, has increased. The majority of the buildings are built by using unreinforced masonry (URM), most of which consists of cavity (i.e. two-leaf) walls, and were not designed to withstand earthquakes. Efforts to define, test and standardize the metal ties, which do play an important role, are valuable also from the wider construction industry point of view. The presented study exhibits findings on the behavior of the metal tie connections between the masonry leaves often used in Dutch construction practice, but also elsewhere around the world. An experimental campaign has been carried out at Delft University of Technology to provide a complete characterization of the axial behavior of traditional connections in cavity walls. A large number of variations was considered in this research: two embedment lengths, four pre-compression levels, two different tie geometries, and five different testing protocols, including monotonic and cyclic loading. The experimental results showed that the capacity of the connection was strongly influenced by the embedment length and the geometry of the tie, whereas the applied pre-compression and the loading rate did not have a significant influence.

Abstract Review Article: Introduction: Registered nurses and students of the Bachelor of Nursing are improving the quality of healthcare by working together in a Learning and Innovation Network (LIN). A LIN is a powerful learning environment, where employees and students work together towards a common goal. Methods: In the Netherlands, Amsterdam UMC, location VUmc and Inholland University of Applied Sciences have set up a LIN on the internal medicine traumatology, oncology, cardiology and urology departments. On the LIN departments, the number of students has increased significantly. Because the students are supernumerary, space and time are created to optimize the learning process of the RNs without compromising the care to be provided. Within the LIN, students learn from the practical experience of RNs, which gives them tools to apply knowledge practically. On the other hand, students can contribute to the adaptation of long established practices, based on recently acquired knowledge. A bridge is built between acting according to recent scientific insights and experiences from practice. It is also important to take the patient’s wishes into account. This guarantees nursing action based on evidence based practice and best practice. Several projects aimed at increasing the quality of care have already been carried out within the LIN such as projects focused on removing a catheter and bandaging. Conclusion: The LIN is taking more and more shape within the VUmc. There is a broad support base between educational and healthcare institutions, both on management and executive level. In order to make the LIN activities even more attuned to the authentic development needs of the department, interprofessional learning and working should be encouraged by also enthusing other care disciplines and researchers to participate in the LIN. An EBP working group consisting of permanent team members can contribute to the safeguarding of the outcomes of the LIN projects.

Cruise tourism is one of the fastest growing sectors worldwide. This book is the first of its kind to provide in-depth insights into the emergence of mega-cruise tourism in destinations on the Arabian Peninsula and its impacts on local communities, their spaces, cultures, identities and tourist experiences. It offers a micro-sociological analysis, calling for holistic, participatory, mindful approaches and to rethink current exploitative tourism planning and development. It assumes a high political, social and economic importance within globalization. It draws on a long-term field study in an under-researched region in Asia that developed large-scale tourism recently to diversify the economy. The book provides insights on the destination development from a state of continuous growth to a sudden fall in tourism activities due to a sudden shock, caused by the global health pandemic and its resilience. It explores the sociocultural, economic and spatial challenges faced in international tourism development and its power relations analysed from different perspectives and within time. It analyses time-space compression, overtourism, urban tourism, nature-based tourism, enclavization, social capital, imaginaries, Cultural Ecosystem Services, slow tourism as well as just tourism. The book provides an innovative contribution to the planning and development of tourism destinations, communities and their spaces in which tourism operates in a fast pace. It will be of interest to academics, undergraduate and postgraduate students in the field of tourism and hospitality management, geography, sociology, anthropology, urban planning and environmental sciences. Moreover, the book will be useful for practitioners and policymakers around the globe, as well as all those interested in the fast emergence and the impacts of mega-cruise tourism.

Kunstmest voor de velden en brandstof voor landbouwvoertuigen zijn belangrijke kostenposten voor de landbouw. Kunstmest en dieselbrandstof zijn energie-intensieve producten en daarmee ook een belangrijke bron van CO2 emissies vanuit de landbouw. Technologie voor hernieuwbare energie zoals zonne- en wind energie wordt steeds goedkoper waardoor het rendabeler wordt deze technologie ook te gebruiken. Terug leveren van geproduceerde hernieuwbare elektriciteit aan het elektriciteitsnet is echter niet altijd voordelig. De hernieuwbare energie moet hier concurreren met gesubsidieerde fossiele elektriciteit opgewekt met kolen, gas en kerncentrales. Kleinschalige decentrale productie op het boerenbedrijf van zowel kunstmest als transportbrandstof met behulp van hernieuwbare energie levert de boer en zijn omgeving direct voordeel op:Inkoopkosten voor deze producten worden lagerVermindert de CO2-emissie van de landbouw aanzienlijk, de carbo-footprint wordt verminderdRendement op hernieuwbare energie technologie wordt hogerAmmoniak (NH3) is zowel grondstof voor kunstmest als brandstof voor motoren. Ammoniak kan diesel voor meer dan 90% vervangen in bestaande dieselmotoren. Daarmee is ammoniak een uitstekende vervanger voor diesel in het landbouw en wegverkeer. Ammoniak is ook grondstof voor waterstof (H2) in waterstofmotoren. De technologie om ammoniak te maken is gebaseerd op het Haber-Bosch proces uit het begin van de vorige eeuw. Deze technologie vraagt veel energie voor het creëren van de hoge druk en de hoge temperaturen. Daarom is het voordelig het Haber-Bosch proces in grote installaties uit te voeren.Nieuwe brandstofcel-technologie maakt het mogelijk het Haber-Bosch proces (elektro-katalytisch) op kleine schaal uit te voeren. Het Kiemkracht concept Greenfertilizer onderzoekt de mogelijkheden van deze technologie voor ammoniak productie en benutting op het eigen boerenbedrijf.Het onderzoek is uitgevoerd door TU-Delft en Hanzehogeschool. Het doel was een opgeschaald ammonia elektrolyse synthese proces te ontwikkelen waar een eerste schaal-sprong gemaakt zou worden.Het elektrochemisch ammonia synthese proces is gebaseerd op zuurstofgeleidende elektroden, (proces figuur3. zie onder). Het voordeel van deze zuurstofgeleidende electroden boven proton geleidende electroden is dat er met omgevingslucht gewerkt kan worden in plaats van met stoom. Stoom maakt technologische ontwikkeling van het proces gecompliceerder. Experimenteel en theoretisch onderzoek van TU-Delft laat zien dat met deze elektroden ammonia te produceren is. TU-Delft heeft met zuurstof geleidende electroden ammonia productiesnelheden behaald van 1,84x 10-10 mol s-1 cm-2 bij 650oC. Deze snelheden zijn een factor 100-1000 hoger dan tot nu toe gerapporteerd in literatuur (Kyriakou et al 2017). Simulatie-studies van TU-Delft laten zien dat het ammonia synthese proces met een factor 100-1000 versneld kan worden door het proces onder druk te brengen bij een temperatuur van 400-500C. Op basis van deze simulaties is een ontwerp gemaakt en uitgevoerd voor een “hoge-druk electrolyse reactor”. Technische complicaties met deze hoge druk elektrolyse reactor maakte het onmogelijk betrouwbare resultaten te verkrijgen. Met name gas lekkages bij hoge temperaturen maakten het onmogelijk ammonia massabalansen op te stellen. Bovendien was ammonia productie niet aan te tonen. Hiermee zijn de simulatie voorspellingen niet bevestigd en blijft het onduidelijk of de onderliggende hypothesen correct zijn. De Hanzehogeschool heeft onderzoek uitgevoerd naar het concentreren van ammonia voor toepassing als vloeibare kunstmest. Uitgangspunt hierbij waren de ammonia productieniveau van de experimentele opzet en de voorspelde gesimuleerde opzet. Met de juiste technologie is het mogelijk de ammonia te concentreren voor verdere verwerking als kunstmest. Echter dit proces is economisch rendabel bij een ammonia concentratie in de uitstroom van de elektrolyse reactor die een factor 1000 hoger is dan tot nu toe is gemeten. Het feit dat de TU-Delft er niet in is geslaagd een kleine schaalsprong (factor 10) te maken met de drukreactor betekent dat commerciële toepassing van dit proces voorlopig nog niet aan de orde is. Achteraf gezien was het wellicht beter geweest de keuze te maken voor de proton geleidende electroden die bij lagere temperaturen werkzaam zijn, hier is een schaalsprong van een factor 100 ten opzichte van de recent gerapporteerde ammonia synthese snelheden. Een recente review door Kyriakou et al 2017 geeft als aanbeveling onderzoek te verrichten naar verbeterde elektrodematerialen en geleidende elektrolyten in de reactorcellen. Uiteindelijk zal het elektrochemisch ammonia synthese proces er komen vanwege de vele voordelen die het beidt. Processen moeten met een factor 100-1000 verbeterd worden eer het proces economisch rendabel is. Op dit moment is het nog niet te voospellen wanneer dit moment er is.

For German-speaking tourists, an Oriental market (in Arabic: souq) is an exotic place representing the ‘Otherness’. Referring to this Oriental context, the article aims to answer the following questions: What are the tourists’ imaginaries and social narratives and what is the role that cultural brokers play? Gaining insight into the imaginaries and on-site performances of German-speaking tourists of a mega-cruise liner will contribute to the discussion of imaginaries and embodied performances in general as well as the mediation and the construction of space. The research reported upon in the article is part of a larger field study (2012–2014) in Souq Muttrah, the oldest and formerly main market in Oman. Participant observation, photography and in-depth interviews with different types of tourists, local customers, cultural brokers and on-board employees were conducted and marketing material was analysed. Results indicate that in the marketing material, the tourists are already beginning to travel backwards in time. During their visit to the souq, the multi-sensory performances and embodied imaginaries are enhanced by stories of the Arabian Nights. Cultural brokers play an essential role in ‘localizing’ the tourist experience. They adjust their own identities and direct the tourists’ performances at different stages, similar to an Oriental theme park, for example, they stop at a frankincense shop.

This paper describes the concept of a new algorithm to control an Unmanned Aerial System (UAS) for accurate autonomous indoor flight. Inside a greenhouse, Global Positioning System (GPS) signals are not reliable and not accurate enough. As an alternative, Ultra Wide Band (UWB) is used for localization. The noise is compensated by combining the UWB with the delta position signal from a novel optical flow algorithm through a Kalman Filter (KF). The end result is an accurate and stable position signal with low noise and low drift.

The 'AgroCycle' project investigates whether a cooperation of farms can become self-sufficient in energy and fertilization by using manure and organic waste streams for the production of energy, green fuel and green fertilizers by means of anaerobic digestion (AD). In the project, the project partners aim to link the nutrient cycle (from manure to digestate to green fertilizer) to a self-sufficient energy system (biomass to biogas to green fuel for processing the land) through the combined production of biogas and green fertilizers. The financial feasibility of a bio-digester is highly dependent on the use and economic value of the digestate. This combined approach increases both feasibility and sustainability (environmental impacts and CO2 emissions). To explore the feasibility of the aforementioned concept, use is made of the existing 'BioGas simulator' model developed by Hanze UAS to simulate the technical process of decentralized production of biogas and the economic cost.
