Mathematical modelling has proven to be very useful in process design, operation and optimisation. A recent trend in WWTP modelling is to include the different subunits in so-called plant-wide models rather than focusing on parts of the entire process. One example of a typical plant-wide model is the coupling of an upstream activated sludge plant (including primary settler, and secondary clarifier

Signal crayfish (Pacifastacus leniusculus) have become increasingly widespread in rivers in Great Britain since their introduction in the late 1970s, causing extensive losses of indigenous white-clawed crayfish and negative impacts on communities of aquatic plants, invertebrates and benthic fish. Angling interests are increasingly concerned about possible impacts of signal crayfish on brown trout,

Kuannersuit Glacier, a valley glacier on Disko Island in west Greenland, experienced a major surge from 1995 to 1998 where the glacier advanced 10.5 km and produced a similar to 65 m thick stacked sequence of debris-rich basal ice and meteoric glacier ice. The aim of this study is to describe the tectonic evolution of large englacial thrusts and the processes of basal ice formation using a multipr

Fluids of spherical colloids possessing an off-centered embedded magnetic dipole were investigated by using Monte Carlo simulations. Systems of colloids with different strengths and directions of the embedded dipole moment confined in a 2D space without and with an external magnetic field applied were considered. The fluids were characterized by radial distribution functions, angular distribution

Cationic polymers are used in anionic surfactant formulations to deposit and co-deposit actives on hair or skin surfaces. A series of cationic polymers, natural and synthetic, were investigated with surface and bulk techniques, turbidity measurements and in situ null-ellipsometry on silica surfaces in order to understand three key areas: the relation between the complex that is formed at a surface

Selection on proteins is typically measured with the assumption that each protein acts independently. However, selection more likely acts at higher levels of biological organization, requiring an integrative view of protein function. Here, we built a kinetic model for de novo pyrimidine biosynthesis in the yeast Saccharomyces cerevisiae to relate pathway function to selective pressures on individu

BACKGROUND AND OBJECTIVES: Transfusion of blood products in particular older products is associated with patient morbidity. Previously, we demonstrated a higher incidence of acute lung injury in lipopolysaccharide-treated sheep transfused with stored blood products. As transfusion following haemorrhage is more common, we aimed to determine whether a 'first hit' of isolated haemorrhage would prec

The basis for this thesis is mainly gathered from Lund University’s Archives of Ecclesiastical History, LUKA. Questionnaires called ”kyrklig sed” are frequently emitted to all Swedish parishes to document different customs within the church. Since 1962 they also contain questions about cribs in the churches. Beside these questionnaires, there are also special questionnaires of different extent. LU

A rotating, two-component Bose-Einstein condensate is shown to exhibit vortices of multiple quantization, which are possible due to the interatomic interactions between the two species. Also, persistent currents are absent in this system. Finally, the order parameter has a very simple structure for a range of angular momenta.

Embryonic development is associated with extensive rearrangements of tissues. The driving force for these rearrangements is generated by a dynamic reorganization of the Actin cytoskeleton of individual cells. In many instances, conserved Rho-family GTPases that are activated by Rho guanine nucleotide exchange factors (RhoGEFs) play an important role in this process. The present thesis investigates

Emerging concepts for on-chip biotechnologies aim to replace microfluidic flow by active, molecular-motor driven transport of cytoskeletal filaments, including applications in bio-simulation, biocomputation, diagnostics, and drug screening. Many of these applications require reliable detection, with minimal data acquisition, of filaments at many, local checkpoints in a device consisting of a poten

Seven new species of Caloplaca are described, the isidiate Caloplaca clavatoisidiata and C. sipmanii, and five fertile species, C. bastowii, C. beaugleholii, C. dahlii, C. jerramungupensis and C. norfolkensis. The new species are distinguished from related species by morphological, anatomical and chemical characters which are described in detail. The new combination Caloplaca soredians (Müll.Arg.)

In this paper we discuss and review results of recent studies of epitaxial growth of graphene on silicon carbide. The presentation is focused on high quality, large and uniform layer graphene growth on the SiC(0 0 0 1) surface and the results of using different growth techniques and parameters are compared. This is an important subject because access to high-quality graphene sheets on a suitable s

Suddendorf, Corballis and Collier-Baker (Anim Cogn 12: 751-754, 2009) comment on a study on great ape foresight (Osvath and Osvath, Anim Cogn 11: 661-674, 2008). That study consisted of four experiments investigating foresight in chimpanzees and orangutans, examining in particular whether the planning they exhibit is best explained by assuming an episodic cognitive system. This system has widely b

A biosensor, based on a redoxactive osmium polymer and sulfite oxidase on screen-printed electrodes, is presented here as a promising method for the detection of sulfite. A catalytic oxidative current was generated when a sample containing sulfite was pumped over the carbon screen-printed electrode modified with osmium redox polymer wired sulfite oxidase. A stationary value was reached after appro

Background: The Dachshund homolog 2 (DACH2) gene has been implicated in development of the female genital tract in mouse models and premature ovarian failure syndrome, but to date, its expression in human normal and cancerous tissue remains unexplored. Using the Human Protein Atlas as a tool for cancer biomarker discovery, DACH2 protein was found to be differentially expressed in epithelial ovaria
