Assessment of laparoscopic instrument reprocessing in rural India: a mixed methods study

Background: Laparoscopy is a minimally-invasive surgical procedure that uses long slender instruments that require much smaller incisions than conventional surgery. This leads to faster recovery times, fewer post-surgical wound infections and shorter hospital stays. For these reasons, laparoscopy could be particularly advantageous to patients...

Integrated design of a semi-submersible floating vertical axis wind turbine (VAWT) with active blade pitch control

A semi-submersible Tri-Floater has been designed to support a 6 MW vertical axis wind turbine (VAWT) with active blade pitch control. Due to the low centre of gravity and large allowable floater tilt angle, a relatively small floater can be used to support a VAWT. Coupled simulations including hydrodynamics, mooring system, aerodynamics and...

Port-city development in Rotterdam: A true love story

This article tells the story of how city and the port have found a joint development strategy for Rotterdam’s CityPorts during the past decade. The process has resulted in more realistic, so-called ‘organic’ development plans, which mark the emergence of a new relationship between the port and the city. In essence, Rotterdam has produced new...

Building Castles in the (Dutch) Air: Understanding the Policy Deadlock of Amsterdam Airport Schiphol 1989 - 2009

Ever since the 1950s, the Dutch national government has struggled intensely with the trade-off between the economic significance and environmental impact of Amsterdam Airport Schiphol, the largest airport of the Netherlands. By 2005, the ambition to combine the growth of ‘Mainport’ Schiphol with comprehensive environmental measures has resulted...
