Model calculations and the few data that are available show that over 100 L water condense yearly on each square meter of a greenhouse cover. It is known that the presence of condensate reduces light transmission. This effect is suppressed to some extent by adding film-forming (anti-drop) additives to …

The Dutch greenhouse horticulture industry is characterized by world leadership in high-tech innovation. The dynamics of this playing field are innovation in production systems and automation, reduction in energy consumption and sharing limited space. However, international competitive advantage of the …

We study optimal incentive contracts for workers who are reciprocal to management attention. When neither worker’s effort nor manager’s attention can be contracted, a double moral-hazard problem arises, implying that reciprocal workers should be given weak financial incentives. In a multiple-agent setting, …

This report was commissioned to examine the possible gap between the image and identity of TUI Nederland regarding sustainable tourism and to recommend on how to bring the image closer to the identity. TUI Nederland is market leader in the Dutch travel industry and carries the brands Arke, Holland International, …

A new CPV system with a static linear Fresnel lens, silicon PV module suitable for concentrated radiation and an innovative tracking system is integrated in a greenhouse covering. The basic idea of this horticultural application is to develop a greenhouse for pot plants (typical shadow plants) which …

I started this particular project with an internship at the European Commission in Beijing, China. Experiencing China's enormous growth myself in the last seven months it was clear to me that China will have an even greater impact on both the economic and political agendas of the Western world and its …

In a double-masked randomized controlled crossover study we investigated both the retinal responses to straylight, and the effects of lens cleaners on straylight values, in two different RGP contact lens materials. Methods: Thirty patients (20-59 years) wearing RGP lenses were refitted with new lenses …

Dit verslag beschrijft een onderzoek naar de verschillen van een steeds meer voorkomende techniek in de skeelersport, de double push. Omdat er weinig wetenschappelijke literatuur geschreven is over de double pushtechniek, wordt de techniek vergeleken met de klassieke skeelertechniek. Voor een beter inzicht …
