Swelling is a common phenomenon after total knee arthroplasty, with potential for negative impact on the rehabilitation process and final outcome. The aim of this study was to investigate the effectiveness of a new compression protocol with a self-adjustable, nonelastic compression wrap for the knee region. This study was conducted as a prospective comparative study. Total leg volume and the circumference of the knee at three levels were compared between groups. The results of our study suggest that the application of the new compression protocol has no effect on swelling in the acute postoperative phase (0-2 days) but reduces swelling at Day 14 within the subacute phase. The observed positive effect of the compression protocol could be of clinical importance in the subacute phase as well as for a subgroup of patients suffering from aberrant quadriceps weakness concomitant with knee swelling.

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.

Dit project sluit naadloos aan op de Nationale transitieagenda circulaire economie voor de materialengroep ThermoPlastische Composieten (TPC): (Ontwikkelrichting 1: Preventie): Dankzij de toepassing van vezels kan zaanzienlijk op het verbruik van materialen worden bespaard, hetgeen bovendien kan leiden tot kostenbesparingen en tot CO2 besparing tijdens de productiefase en de gebruiksfase. (Ontwikkelrichting 2: Meer hernieuwbare kunststoffen): Door toepassing van gerecyclede en biokunststoffen, die vervolgens ook goed recyclebaar zijn en in de meeste gevallen bioafbreekbaar wordt een belangrijke bijdrage aan de hernieuwbaarheid geleverd. Het Lectoraat Lichtgewicht Construeren verricht al meer dan 5 jaar onderzoek naar industriële verwerkingstechnieken voor TPCs ten behoeve van grootserie producten, maar tot nog toe is nauwelijks onderzoek verricht naar beoogde materialen. Het Lectoraat Sustainable Polymers van de NHL Stenden hogeschool verricht al jaren onderzoek naar bio-gebaseerde en bioafbreekbaar thermoplasten en vezels. Hoewel er ook al veel toegepaste kennis is opgedaan met biocomposieten, zijn de cruciale verwerkingstechnieken in dit project geheel nieuw voor het betrokken lectoraat, en ook geheel nieuw in de TPC markt. Nieuw in dit project betreft daarom de circulariteit van de te onderzoeken TPC materialen in combinatie met de nieuwste grootserie productietechnieken. Iedere vezel-thermoplast combinatie heeft zijn specifieke eigenschappen ten aanzien van maakbaarheid, verwerkbaarheid en uiteindelijke eigenschappen bij gebruik. Deelnemende bedrijven willen de circulariteit van hun materialen nog verder vergroten en hebben daarom behoefte aan verder onderzoek. De centrale onderzoeksvraag luidt: In hoeverre zijn circulaire thermoplastische composieten te ontwikkelen die seriematig te verwerken zijn met de nieuwste TPC-processen? Bij de uitwerking van de onderzoeksvraag richten we ons concreet op onderzoek naar: • Produceerbaarheid van halffabricaten (commingled weefsels, tape, inserts) van circulaire TPCs • Verwerkbaarheid in producten en recyclebaarheid van circulaire TPCs • Bepalen van materiaalprestaties, waaronder: mechanische eigenschapen, levenscyclus analyse (LCA) en bestendigheid tegen weersinvloeden van circulaire TPCs
Worldwide the demand for lactic acid is rapidly rising due to its applications as a biobased platform chemical for the production of biopolymers through polylactic acid (PLA). Unfortunately, these more sustainable alternatives to fossil-based chemicals are still too expensive, which is a major obstacle to its adoption. Raw materials make up to a third of the total production costs of industrial lactic acid production, which currently fully dependents on the use of refined sugars as its main source of biomass feedstock. Nature’s Principles has developed an innovative technology to effectively convert alternative low-value biomass streams into lactic acid using mixed microbial cultures in combination with novel downstream processing technologies such as Mechanical Vapor Recompression (MVR). Based on preliminary techno-economic modelling, this integration can lead to a substantial reduction in feedstock costs for lactic acid production and a lower overall carbon footprint. Another barrier to PLA’s adoption is in consideration of its end-of-life scenarios. Recycling of PLA is considered a promising route. TORWASH is developing technology to recover lactic acid from waste PLA with a minimal carbon footprint, but to achieve specifications for polymer-grade lactic acid and reduce the costs of recovered LA, the parameters for downstream processing need to be further developed. This project will focus on the essential downstream processing steps for solid and water removal with a focus on lactic acid produced from cellulose rich wastewater and agricultural residuals and recycled PLA.
Lymphedema is one of the most poorly understood, relatively underestimated and least researched complications of cancer, or its treatment. Lymphedema is a chronic condition that causes abnormal build up of fluid under the skin resulting in painful swelling, commonly in the arms and legs. Limpressive Compression Garments have designed and conceptualised an active and smart compression sleeve that integrates pioneering smart materials and sensor technology to be used to treat and evaluate lymphedema. The Limpressive garments can be used as a research tool while replacing existing compression sleeves and pneumatic compression apparatus. There is currently no product on the market that is integrating both the actuator and sensor technology to treat, let alone quantify lymphedema. It is thus imperative that the Limpressive Compression Garments team are allowed the opportunity through funding to investigate the feasibility of the technology and its integration into healthcare, the business structures and processes needed to enter and be successful in the marketplace and the value to both the consumer and to the organisations dedicated to developing a greater understanding of the disease. Limpressive will complete an extensive and detailed business plan and a complete product design by the end of the Take-off Phase. The business plan and complete product design will be complemented by a proof of function prototype.
