Popular Abstract in Swedish För analys av agroekosystems näringsämnescirkulation presenteras här en generell modell. I centrum står födoproduktionsintensitet, mänsklig bärförmåga, uthållighet och effektivitet. Modellen kan användas på system med flera markanvändningstyper och är därför lämpad för studier i olika skalor. Jämförelser av alla slags agroekosystem, oavsett tid och rum, är möjliga. OlikThis study presents a general model for analysing nutrient cycling in agroecosystems. The focus is on food production intensity, human carrying capacity, sustainability and efficiency. The model can be used on systems including different kinds of land uses, which makes it applicable for studies on different scales. Comparisons of all kinds of agroecosystems, independent of time and place, are made

In this paper, the author discusses the most common approaches to the supply chain problem. The author argues that they rest on static ideas while the supply chain network is better viewed as an ongoing activity for which the suggested methods are inappropriate. Hence, none of the popular methods has a suitable model of the problem. Instead he suggests infinite games as a computational model for t

At the Faculty of Engineering at Lund University, two of the engineering programmes have decided to strengthen and systematise the students’ communication training during the curriculum. The project addresses two different levels: the engineering teachers of the programme are offered further education while the programme managers are responsible for the progression during the curriculum. The teach

This thesis investigates the adsorption, decomposition and reactions of small molecules on flat, oxidised and vicinal surfaces of late transition metals. The main technique for these studies is high resolution core level spectroscopy (HRCLS). All the studies presented in the thesis are performed in Ultra High Vacuum (UHV). The articles can be divided into three groups. The first three articles dea

The present dissertation delineates how the fairy tale character, Little Red Riding Hood, has appeared in different screen versions. It is a thematic and historical analysis of the development of film versions and other traces of the story 1901 to 2001, focussing particulary on the representation of Red Riding Hood herself. The story of this little girl, mostly dressed in different red garments, i

This article deals with the question of heteronormativity, or more precisely, how heteronormativity pertains to the reception of the Swedish film by Lukas Moodysson, Show Me Love (Fucking Åmål).

Popular Abstract in English Cells are the basic unit of life that exhibit dependence on water and ambient temperature to flourish and survive. So it is remarkable that the proteins responsible for the interaction of water and heat with the cell were not discovered until relatively recently. It was assumed for decades that water freely diffuse into and out of the cells without support. The cells arMembrane proteins play several important roles in a cell. Among these proteins are aquaporins (AQPs) and transient receptor potential (TRP) ion channels that mediate water transport, temperature and noxious chemical sensation, respectively. The function of some AQPs, for example the spinach isoform SoPIP2;1 is regulated by pH, phosphorylation and heavy metals such as mercury. However, the mechanis

The Swedish Program "Leadership, Organization and Communication" (LOM) was a research and a development program designed to support local processes of change in the private and the public sector. The program was carried out between 1985 and 1990. The strategy of LOM was focused on two basic principles: the principle of democratic dialogue and the principle of development of a "communicative infras

The question at stake is to what extent could the Hungarian intelligentsia, here foremost represented by the author and political thinker József Eötvös, in the beginning of the 19th century, take in the ideas of the Enlightment and its notion of equality. By studying Eötvös' highly political novel "Village Notary" some conclusions are made regarding how Rousseau's political philosophy was understo
