Popular Abstract in English A food web is a network diagram that describes which species that eat each other in nature. Such networks in marine environments e.g. show that cod eat herring, sprat, and sandeel - and that these eat numerous other species. Understanding of these relationships is a fundamental scientific problem, which can be used to assess the consequences for the stocks when we e.g. This thesis sets out a food web framework for size-structured populations. The framework enables an ecological approach to food web modelling as the individual life-history from birth, through maturation, and ultimately death is explicitly resolved with the use of bioenergetics based on individual body size. Each population resolves size-structure through a size-spectrum containing the individual

One of the major arguments made in the current boom in Haitian revolutionary studies connects today’s conditions of possibility for modern democracy and human rights to the abolition of slavery during the Haitian Revolution (1791–1804). During the last decade, however, this connection between the Haitian Revolutionary period and our own age has been questioned by an increasing number of scholars: One of the major arguments made in the current boom in Haitian revolutionary studies connects today’s conditions of possibility for modern democracy and human rights to the abolition of slavery during the Haitian Revolution (1791–1804).

The load transfer and redistribution phenomenon that occurs through the mobilization of shear stresses in response to relative displacements in granular materials, such as soils, is attributed to the arching effect. The arching effect has a great influence on the behaviour of soils and plays an important role in predicting earth pressure in granular backfills of limited extent, confined by unyield

This thesis consists of two parts. In the rst part, the iterative data-adaptive BIAA spectral estimation technique was extended to estimate lateral blood velocities using ultrasound scanners. The BIAA method makes no assumption on samples depth or sampling pattern, and therefore allows for transmission in duplex mode imaging. The technique was examined on a realistic Field II simulation data set,

Popular Abstract in English The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where most steel sheet pile walls have cap beams of reinforced concrete. The degradation processes of these structures must be taken into account both when designing new structures and when inspecting The two most used building materials in harbor structures are undoubtedly steel and concrete.

Popular Abstract in English Living organisms are composed of mainly carbohydrate, protein and lipid molecules. Protein molecules are responsible for many biological functions in cells. In order to fulfill their various biological roles, these chain-like molecules must fold into precise three-dimensional shapes.

In order to fulfill their various biological roles, these chain-like molecules must fold into precise three-dimensional shapes. The knowledge of accurate molecular structures is a prerequisite for rational drug design and for structure based functional studies. Getting structural information of proteins can be a very difficu

Fracture behavior of an ultra thin Aluminium foil was studied. For very short crack lengths, fracture has been followed in the scanner electronic microscope (SEM) with a tensile stage. A single edge notched tension specimen was used. Crack length and applied load during the crack growth were measured. These results have been used to calculate fracture strength using linear elastic fracture mechani

We study how star formation is regulated in low-mass field dwarf galaxies (⁠105≤M⋆≤106M⊙⁠), using cosmological high-resolution (⁠3pc⁠) hydrodynamical simulations. Cosmic reionization quenches star formation in all our simulated dwarfs, but three galaxies with final dynamical masses of 3×109M⊙ are subsequently able to replenish their interstellar medium by slowly accreting gas. Two of these galaxie

The modern economy has put an emphasis on team-led work in both large- and small-scale projects. This has led to ways to maximize the effectiveness of teams, with an increasing focus being put on one key concept: psychological safety. The aim of this study is to examine the relationship between psychological safety and team effectiveness through the use of a cross-sectional study design on an IT p

In conventional cell lysate protocols, cell debris is typically discarded to obtain a cleaner lysate. However, this approach has limitations, as it may overlook vital cellular components. By discarding cell debris, researchers may inadvertently exclude crucial elements. Retaining all cellular components offers several advantages for studying molecular biology within various cellular compartments.

With the growing pool of deposited protein structures, the need for structural analysis tools grows. In study of amino acid substitutions the variety of analysis tools is high; nevertheless, there is a lack of programs serving specific purpose, such as identifying if an amino acid substitution would cause a clash in the structure or not, given just the structure of the original protein. In this stAnalysing structural damage caused by changes in proteins In an organism, even only one single change of an amino acid can sometimes lead to disease, if the protein is a part of an important biological function. Because of that, it is important to study those changes and be able to predict if an amino acid substitution would cause harm. There are various ways a substitution can be harmful to a pr

Popular Abstract in English In the age where there is a great demand of energy, raise in the prices of fossil fuels and increase of environmental concerns because of the greenhouse gas emissions, biogas production through anaerobic digestion, of different organic materials, provides a full or partial solution. There is a large number of cheap substrates as organic waste materials that can be utiliThe anaerobic digestion process results in the production of biogas from a large diversity of organic residues, which can be used as an alternate source of energy generation and for waste management. However, the biogas production technology is not exploited efficiently due to the characteristics of raw materials, poor methane yields, process instability, limited raw materials and lack of knowledg
