We describe the University of Amsterdam’s participation in the INEX 2005 Interactive Track, mainly focusing on a comparative experiment, in which the baseline system Daffodil/HyREX is compared to a home-grown XML element retrieval system (xmlfind). The xmlfind system provides an interface for an XML information retrieval search engine, using an index that contains all the individual XML element...

In the area of information retrieval the concept of relevance feedback is used to provide high relevant documents to the user. The process of gaining relevance data is usually based on explicit Relevance Feedback. But it turned out, that users are usually not willing to provide such data. This paper describes a Relevance Feedback approach that supports the users with query expansion terms by us...

PREMISE OF THE STUDY Microsatellite markers were developed using hoop-petticoat daffodils (Narcissus sect. Bulbocodii; Amaryllidaceae) to aid in the taxonomic revision of the section, and to further evaluate their broad applicability for daffodil cultivar identification. METHODS AND RESULTS Three hundred fifty-one primer pairs were developed using a commercial service. Nineteen polymorphic an...

The Mediterranean coastline is a dynamic and complex system which owes its complexity to its past and present vicissitudes, e.g. complex tectonic history, climatic fluctuations, and prolonged coexistence with human activities. A plant species that is widespread in this habitat is the sea daffodil, Pancratium maritimum (Amaryllidaceae), which is a perennial clonal geophyte of the coastal sands o...

Galanthamine is an Amaryllidaceae alkaloid used to treat the symptoms of Alzheimer's disease. This compound is primarily isolated from daffodil (Narcissus spp.), snowdrop (Galanthus spp.), and summer snowflake (Leucojum aestivum). Despite its importance as a medicine, no genes involved in the biosynthetic pathway of galanthamine have been identified. This absence of genetic information on biosy...

abstract reduction of post harvest losses in cut flowers and increasing their vase life, with consideration to high expenses of production is very necessary. one of the effective factors is presence of flowers near each other. this study was performed to investigate the interaction of some important cut flowers on their post harvest characteristics in vase solution (in combination or alone) in ...
