Local controlled release of corticosteroids extends surgically induced joint instability by inhibiting tissue healing

Background and Purpose: Corticosteroids are intra-articularly injected to relieve pain in joints with osteoarthritis (OA) or acute tissue damage such as ligament or tendon tears, despite its unverified contraindication in unstable joints. Biomaterial-based sustained delivery may prolong reduction of inflammatory pain, while avoiding harmful...

Developing an outdoors game for children

One out of seven primary school children is suffering from overweight and sometimes even obesity. This is caused by a lack of physical activity and unhealthy food diets. Children playing outdoors is positively and significantly associated with the child’s physical activity. Peerdrops is a small Dutch company that creates product, graphic and...

Notional Permeability

Different layer design of a rock slope and under layers has a large effect on the strengths on the rock slope itself. In the stability formula developed of VAN DER MEER [1988] this effect is represented by the term Notional Permeability with symbol P. A more open, or permeable, structure underneath the armour layer has the ability to dissipate...

The notional permeability of breakwaters: Experimental research on the permeability factor P

The stability formula developed by Van der Meer is used for the design of different kind of rock slopes. In the formula is among a number of other parameters also the permeability of the structure represented. A more permeable structure has the ability to dissipate more water and therefore more energy, this results into a lower required weight...

Fieldwork coastal engineering: Varna, Bulgaria

One week the students stay in the Bulgarian village St. Konstantin, near Varna, at the Black Sea. The main goal of the fieldwork is learn how to deal with problems occurring at data collection and the elaboration and interpretation of the collected data. Several coastal measurements are executed at a couple of beaches and their accompanying...

Metingen scheepsgeïnduceerde waterbeweging Prinses Margrietkanaal nabij Uitwellingerga

In deze notitie wordt de omvang van de waterbeweging gepresenteerd, die tijdens een meetcampagne in het Prinses Margrietkanaal is gemeten met de SVI-meetset. Naast deze waterbeweging wordt het aantal scheepspassages tijdens de metingen aangegeven. Deze steekproef levert een relatie op tussen het aantal gepasseerde vaartuigen en de door deze...
