Design and In Vitro Validation of an Orthopaedic Drill Guide for Femoral Stem Revision in Total Hip Arthroplasty

Objective: Cemented total hip arthroplasty (THA) demonstrates superior survival rates compared to uncemented procedures. Nevertheless, most younger patients opt for uncemented THA, as removing well-fixed bone cement in the femur during revisions is complex, particularly the distal cement plug. This removal procedure often increases the risk...

Mangrove ecosystem properties regulate high water levels in a river delta

Intertidal wetlands, such as mangroves in the tropics, are increasingly recognized for their role in nature-based mitigation of coastal flood risks. Yet it is still poorly understood how effective they are at attenuating the propagation of extreme sea levels through large (order of 100 km2) estuarine or deltaic systems, with complex geometry...

Modular Smart Design of Tuber Washing Lines: A Novel Design Approach

Tummers Food Processing Solutions is an internationally operating company based in the Netherlands, that sells factory lines for processing tuberous products like potatoes. Before being processed into various products, the incoming tuber batches are always washed and cleaned from waste particles like clods, stones and haulm. For this purpose...

Plant traits determining biogeomorphic landscape dynamics: A study on clonal expansion strategies driving cliff formation at marsh edges

Despite the well-recognized importance of plant traits for biogeomorphic development of landscapes, our understanding remains limited of how species-specific plant traits respond to and serve as drivers for the sedimentary dynamics within a biogeomorphic landscape. By manipulating a series of laboratory experiments, using mesocosms and a...

Salt marsh establishment in poorly consolidated muddy systems: effects of surface drainage, elevation, and plant age

Conservation and restoration of salt marsh ecosystems are becoming increasingly important because of the many ecosystem services they provide. However, the processes controlling salt marsh establishment and persistence, especially on bare tidal flats in muddy areas, remain unclear. As muddy sediments typically experience a restriction of soil...

Historic storms and the hidden value of coastal wetlands for nature-based flood defence

Global change amplifies coastal flood risks and motivates a paradigm shift towards nature-based coastal defence, where engineered structures are supplemented with coastal wetlands such as saltmarshes. Although experiments and models indicate that such natural defences can attenuate storm waves, there is still limited field evidence on how...

Short-term mudflat dynamics drive long-term cyclic salt marsh dynamics

Our study aims to enhance process understanding of the long-term (decadal and longer) cyclic marsh dynamics by identifying the mechanisms that translate large-scale physical forcing in the system into vegetation change, in particular (i) the initiation of lateral erosion on an expanding marsh, and (ii) the control of seedling establishment in...

Zetting door wegophoging - casestudie A2 Holendrecht Maarssen

De toepasbaarheid van recente zettingsmodellen in MSettle 8.2 is geëvalueerd, door toetsing aan metingen op de A2 verbreding nabij Vinkeveen. De dikke veenlaag is daar versneld samengedrukt door gebruik van verticale drains en tijdelijke voorbelasting. Naast weggenomen overhoogte is op een deel ook voorbelast door tijdelijke onderdruk (BeauDrain...

Problematische scheepvaartpassages op het Noordzeekanaal

Voor het havengebied van Amsterdam is de verwachting dat toenemende scheepsafmetingen en een groeiende verkeersintensiteit in de toekomst zullen leiden tot meer problematische scheepvaartpassages op het Noordzeekanaal. Het is echter moeilijk te bepalen in hoeverre scheepvaartpassages problematisch zijn, aangezien criteria voor dergelijke...
