Popular Abstract in Swedish Inom växtriket finns det ca 3000 arter som är parasitiska och dessa växer i nästan alla större ekosystem på land. Parasitiska växter kan delas in på olika sätt, helparasiter respektive halvparasiter. Denna indelning baserar sig på om de saknar klorofyll och tar all sin näring från sin värdväxt (helparasiter) eller har klorofyll och kan själva framställa kolhydrater men Parasitic plants are found in nearly every major terrestrial ecosystem and can be divided into two groups, holoparasites (lacking chlorophyll) and hemiparasites (chlorophyllous). The host-parasite connection is either situated above (stem parasites) or below ground (root parasites). In this thesis I examine the host-parasite interactions, host range and selection, and population dynamics of four r

In the chapter, “Trade Unions and Collective Agreements in a Changing World”, Anders Kjellberg explains why Swedish union density still is very high from an international perspective and why it fell dramatically in the years 2007 and 2008, particularly among Young and foreign-born employees, both containing a high share of precarious workers. Also, a number of long-term factors pressing union dens

Många idéer cirkulerar kontinuerligt inom och mellan olika fält i samhället. En del av dessa idéer blir på modet och betraktas som legitima lösningar på olika slags problem. Bland dessa kan organisationer – såväl offentliga som privata - lätt hitta färdiga paketlösningar till hur de exempelvis skall styra, leda eller budgetera sin verksamhet. Kvalitetssäkring blev en sådan idé på modet inom hälso-

This work presents an extension of a design procedure for dynamic output feedback design for systems with nonlinearities satisfying quadratic constraints. In this work we used an axial gas compressor model described by the 3-state Moore-Greitzer compressor model (MG) that has some challenges for output feedback control design (Planovsky and Nikolaev 1990), (Rubanova 2013). The more general constra

The article dicusses the etymology of three preliterary Common Nordic prepositions: till 'to', hos 'at', från 'from'. Phonological, morphological, syntactic and semantic aspects are taken into account to explain the grammaticalization processes.

The editors and contributors reflect on ethics and reflexivity in critical management research, and explore the identity of the critical researcher both as an individual and working within collaborative projects. Using contemporary accounts from those engaged in real world fieldwork they outline what critical management is, and explore its relationship to management research. The book discusses t

Classification of song similarities and differences in one bird species is a subtle problem where the actual answer is more or less unknown. In this paper, the singular vectors when decomposing the multitaper spectrogram are proposed to be used as feature vectors for classification. The advantage is especially for signals consisting of several components which have stochastic variations in the amp
