Oxygen transport and consumption in germinating seeds

Three mathematical models were formulated to describe the oxygen con-sumption of seeds during germination. These models were fitted to measure-ment data of oxygen consumption curves for individual germinating seeds of Savoy cabbage, barley and sugar beet provided by Fytagoras. The first model builds on a logistic growth model for the increasing population of mitochondria in the embryo during growth. The other two take the anatomy and physiologi-cal properties of the seed into account. One describes the oxygen uptake during the germination phase only. An extension of this model is capable of fitting the complete oxygen consumption curve, including the initial ‘repair’ phase in which the embryonic cells recover from their dormant state before extensive cell division and growth commences. Keywords: Modelling, seed germination, cellular respiration, oxygen transpor

Up and beyond: Building a mountain in the Netherlands

We discuss the idea of building a 2 km high mountain in the Netherlands. In this paper, we give suggestions on three important areas for the completion of this project. Issues like location, structure and sustainability are investigated and discussed in detail

A greenhouse growth model for unselfish roses

In februari 2002 vond de tweeënveertigste StudiegroepWiskunde met de Industrie plaats. Een van de problemen betrof het modelleren van de groei van kasrozen. Het uiteindelijke doel van de studie is het construeren van een model dat door middel van terugkoppeling het klimaat in een kas zo regelt dat een optimale groei wordt verkregen. Het probleem is aangedragen door het bedrijf Phytocare, een adviesbureau voor rozenkwekers

Study groups with industry are meetings where people from industry join forces with mathematicians to tackle industrial problems. The first such meeting was held in the sixties at the University of Oxford. Nowadays study groups with industry are organised in many countries, e.g. Australia, the USA and several European countries. Since 1998 study groups with industry are also organised in The Netherlands. In 1998 a study group was hosted by the University of Leiden, in 1999 by the University of Eindhoven, in 2000 by Twente University, in 2002 by the CWI and the University of Amsterdam, and in 2003 the study group was hosted by the University of Leiden again. The next study group will take place in Delft, in March 2004. For up-todate information please follow the links www.wiskgenoot.nl/swi or www.stw.nl. The 45th European Study Group with Industry was organised by the University of Leiden at the Lorentz Center. The programme was supported by the section Industriële en Toegepaste Wiskunde (ITW) of the Wiskundig Genootschap, with financial support from the technology programme Wiskunde Toegepast of the technology foundation STW and the EW (Exact Sciences) programme of The Netherlands Organisatio
