Popular Abstract in Swedish En växt är under hela sin livstid utsatt för angrepp från organismer som helt eller delvis försöker äta den. Allt växtmaterial äts faktiskt upp förr eller senare. När växten är död ser nedbrytare till att inget av det kol som växten under sin livstid tagit upp från luften går till spillo. En intressant ekologisk fråga är varför vår värld (i allmänhet) är grön när det fiThis thesis discusses aspects of feeding habits of moose (Alces alces) and their impact on forest development. The development of forage that is available to moose was studied by sampling the amount of edible biomass on pine and birch trees. A strong relationship was found between foliage (and twig) biomass and tree diameter, which corroborates the hypothesis that sapwood area limits the amount of

DNA- cationic amphiphile and DNA-cationic polymer systems were studied with respect to the intermolecular interactions, as well as structure and stability of formed complexes. The thesis is divided in two parts: one section is a summary and the other section contains five papers. The summary is organized as follows; Chapter 2 gives an overview on the behavior of polyelectrolytes in solutions with

Bilateral foreign aid negotiations between industrialized and less developed countries; based on conference paper. Characteristic features of foreign aid negotiations, as compared to other types of negotiations between states; influence of factors which are external in relation to the negotiations themselves.

A box-tree is a bounding-volume hierarchy that uses axis-aligned boxes as bounding volumes. The query complexity of a box-tree with respect to a given type of query is the maximum number of nodes visited when answering such a query. We describe several new algorithms for constructing box-trees with small worst-case query complexity with respect to queries with axis-parallel boxes and with points.

Although up to 30% of babies born with haemophilia do not have a family history of the disorder, the remaining 70% are born in families where haemophilia has been diagnosed. It has been estimated that for each male with haemophilia, there are five potential female carriers. Such women will benefit from knowledge of both their genetic (mutation present or not) and phenotype (level of plasma factor

This paper deals with the Cauchy problem for hyperbolic so-called stiff systems in one space dimension with large relaxation term depending on a small parameter $delta$. In this case the symmetrizer for the modified symbol of the system, in general, depends on the wave number $omega$ and does not define a quadratic entropy. Therefore, the concept of stiff well-posedness of the Cauchy problem appea

The overwhelming majority of small nucleolar RNAs (snoRNAs) fall into two clearly defined classes characterized by distinctive secondary structures and sequence motifs. A small group of diverse ncRNAs, however, shares the hallmarks of one or both classes of snoRNAs but differs substantially from the norm in some respects. Here, we compile the available information on these exceptional cases, condu

The aim was to compare urinary symptoms and their influence on daily life among elderly (75+) women and men in a sample that previously had reported difficulties controlling urine (urine incontinence (UI)) and/or other urinary symptoms (OU). A further aim was to find underlying structures of urinary symptoms and to identify symptoms that had an impact on seeking medical help and need of help in da

Popular Abstract in Swedish Avhandlingen består av fyra kapitel. Efter det inledande kapitlet används i kapitel två och tre ekonomiska experiment för att undersöka hur deltagare fördelar ett överskott mellan sig då det finns två fokalpunkter. Kapitel fyra undersöker huruvida en penningpolitisk störning har asymmetriska effekter på de svenska länens sysselsättning. I kapitel två, samförfattat med This thesis consists of two parts. The first part uses economic experiments to investigate how participants choose to divide a surplus in the presence of competing focal points. The second part examines whether a monetary policy shock has asymmetric regional effects. Chapter 2 suggests a simple separation mechanism based on heterogeneity among subjects to understand how they choose equilibrium wh

Starch is a common ingredient in many products, influencing properties such as viscosity, stability, sensory properties and appearance. These properties and how they change with time in the process called retrogradation are dependent on the structure of starch and its interaction with other components such as lipids and proteins. Lipids, which are present in many starches and products, play an imp

This paper presents our contribution in the closed track of the 2008 CoNLL Shared Task. To tackle the problem of joint syntactic--semantic analysis, the system relies on a syntactic and a semantic subcomponent. The syntactic model is a bottom-up projective parser using pseudo-projective transformations, and the semantic model uses global inference mechanisms on top of a pipeline of classifiers. Th

The free Modelica library ThermoFluid was developed for simulation ofthermo-hydraulic applications, both for single-species applicationslike the water-steam cycle in a thermal power plant and formulti-species applications with gas mixtures. It has demonstratedits flexibility for modeling thermodynamic and process applicationsin a variety of industrial and academic projects. This articledescribes h

Both Peirce and Husserl suggested that a community of scholars were needed to bring to fruition the work that they had initiated, and both (initially) termed their approach phenomenology, defining it in almost identical terms. The fact that Peirce imposed more constraints on the free variation in imagination, which is one of the principal operations of phenomenology, serves to suggest that Peircea

III-V nanowires have tunable dimensions, between 40 nm and 100 nm in diameter and between 1 and 15 μm in length. Due to their small diameter, they are ideal candidates to interact with cells without detrimental effects on the cell viability. Nanowires can be used as sensors: in our case, we have shown that arrays of vertical gallium phosphide nanowires are promising materials for biosensing in mem

One way to deal with product lines and products that have to exist in many variants is to use a component-based approach. This allows a lot of flexibility in creating new products and can reduce time and costs. However, the flexibility in composing products from a base of components is not without problems. Complexity increases in the composition process when combining many components to one large

In this paper, we present an approach for acquiring textured 3D models of room-sized indoor spaces using a quadrocopter. Such room models are for example useful for architects and interior designers as well as for factory planners and construction man- agers. The model is internally represented by a signed distance function (SDF) and the SDF is used to directly track the camera with respect to the

This work studies Nash equilibria for games where a mixture of coordinating and anti-coordinating agents, with possibly heterogeneous thresholds, coexist and interact through an all-to-all network. Whilst games with only coordinating or only anti-coordinating agents are potential, also in the presence of heterogeneities, this does not hold when both type of agents are simultaneously present. This
