The paper deals with the effect of wastewater, plant design and operation in relation to biological nitrogen and phosphorus removal and the possibilities to model the processes. Two Bio-P pilot plants were operated for 2.5 years in parallel receiving identical wastewater. The plants had SRT of 4 and 21 days, the latter had nitrification and denitrification. The plant with 4 days SRT had much more
The recycling heparan sulfate (HS)-containing proteoglycan glypican-1 (Gpc-1) is processed by nitric oxide (NO)-catalyzed deaminative cleavage of its HS chains at N-unsubstituted glucosamines. This generates anhydromannose (anMan)-containing HS degradation products that can be detected by a specific antibody. Here we have attempted to identify the intracellular compartments where these products ar
Laser Doppler flowmetry (LDF) was used to study skin blood flow in the finger tip and on the dorsum of the hand in healthy volunteers. Vasodilatation in the finger tip was induced by immersing the arm in water at 42 degrees C, and vasodilatation in the dorsum of the hand by intracutaneous injection of dihydralazine. Simultaneous measurements were performed using venous occlusion plethysmography (f
Alzheimer´s Disease (AD) is a progressive neurodegenerative dementia characterized by the extracellular accumulation of the beta-amyloid (Ab) peptide into plaques and intracellular phosphorylation and accumulation of tau protein into neurofibrillary tangles (NFT). Inflammation due to astrocytic and microglial activation is one of the ongoing processes in the disease giving rise to cytokine product
Popular Abstract in Swedish FISKETS EFFEKTER BEROR PÅ SAMSPELET MELLAN ARTER Fiske och jakt, så kallad populationsbeskattning, påverkar den fiskade eller jagade populationen på en rad olika sätt. Den direkta effekten är uppenbar: dödligheten ökar, och antalet individer i populationen minskar. I förlängningen påverkar denna minskning också andra arter, som t ex äter eller äts av individerna i den bHarvesting changes population abundance and can affect adaptation of several life-history traits. Harvesting can also have indirect effects ? effects on non-target species and secondary effects on target species ? because interactions between species in a community determine the relevant ecological and evolutionary feedback environment. Species interactions therefore influence the effect of harves
This article discusses problems concerning the use of colour in botanical illustrations, focusing on a specific species, the Orchis ustulata (Burnt Orchid). In 1901–1905 the Swedish botanist Carl Lindman (1856–1928) was responsible for the publication of the Swedish flora Bilder ur Nordens flora, that was, in some ways, a reworking of J. W. Palmstruch’s Svensk botanik (1802–1843).

Popular Abstract in Swedish Syftet med denna avhandling är att studera den vanligaste behandlingskomplikationen vid blödarsjuka, antikroppsbildning, samt att studera sambandet mellan genen som orsakar sjukdom och det protein som denna gen kodar för. Det övergripande syftet är att forskningsresultaten ska kunna användas för att förbättra vården för familjer med blödarsjuka (hemofili). Resultaten vThe general objective of the research underlying this dissertation was to conduct clinical and basic scientific studies to further elucidate the hemophilia and the coagulation process, with the goal of improving the care of families with these disorders. More specific aims were to evaluate epidemiological, genetic, clinical, and biochemical aspects of the development of inhibitors (antibodies) aga
Capacitive biosensors were developed for several analytes such as hormones, interleukines, viruses and heavy metal ions. The sensing surfaces were prepared by immobilizing the biorecognition element to self-assembled monolayers (SAMs) on gold. SAMs form spontaneously on gold by adsorption of thiols, sulfides or disulfides. After immobilization of the biorecognition element a long chain hydrocarbon
Popular Abstract in Swedish Lunds strängfragmenteringsmodell beskriver hur färgade partiklar (kvarkar och gluoner, tillsammans kallade partoner) som produceras vid högenergetisk partikelkollisioner omvandlas till färgneutrala hadroner. Denna avhandling utvecklar och utforskar ett alternativt tillvägagångssätt till modellen. Den nya infallsvinkeln förbättrar modellen för system som består av många The Lund string fagmentation model was reformulated as a process along the boundary curve of the string called the directrix, in order to treat multigluon strings according to the Lund model area law. It was found that the hadrons in the final state could be collected into several groups, in such a way that the energy-momenta of the hadrons in a group lie in a plane in the Minkowski space within s
Popular Abstract in Swedish Isocyanater är en grupp kemiska ämnen som framförallt används vid tillverkning av polyuretan (PUR). PUR förekommer i många olika varianter och är ett av de vanligaste plastmaterialen i våra hem. PUR finns som ”skumgummi” i madrasser, möbler och i bilar, men även i en mängd andra produkter som t.ex. färg, lack och lim. Det finns en risk för isocyanatexponering vid framsIsocyanates are used in the production of polyurethane (PUR). Exposure to isocyanates is associated with respiratory disorders and may occur during production or processing of PUR. During thermal degradation of PUR, amines and aminoisocyanates are formed in addition to isocyanates. Some isocyanates and several aromatic amines are sensitizers and listed as carcinogens. A liquid chromatography mass
Minor structural changes on the surface of proteins can have tremendous impact on their biological properties. When producing therapeutic proteins it is therefore important to verify that the generated protein is the desired one. Small variations such as glycosylations or amino acid substitutions can mean the difference between a functional, defective or even toxic product. This thesis describes
The importance of understanding the prodromal phase of Parkinson’s disease (PD) by systematic recording of prediagnostic symptoms and reductions in body functions has been highlighted. The aim of this study was to investigate whether persons later diagnosed with PD exhibit increased physician-certified sickness absence 1, 2, and 5 years prior to a first sick-leave episode attributed to PD. A case-
The article describes a new method for determining the biological age (BV) of a person, developed by a team of authors: A. Skrebneva, V. Popov, A. Buslova. The goal and objectives are to develop a new method for assessing BV with determining its validity and usefulness for predicting the rate of aging in the framework of a large national sample of people.

Anthropogenically induced changes in precipitation are projected to generate increased river runoff to semi-enclosed seas, increasing loads of terrestrial dissolved organic matter and decreasing salinity. To determine how bacterial community structure and functioning adjust to such changes, we designed microcosm transplant experiments with Baltic Proper (salinity 7.2) and Bothnian Sea (salinity 3.
Anaplastic thyroid cancer (ATC) is a rare and extremely malignant tumor with no available cure. The genetic landscape of this malignancy has not yet been fully explored. In this study, we performed whole exome sequencing and the RNA-sequencing of fourteen cases of ATC to delineate copy number changes, fusion gene events, and somatic mutations. A high frequency of genomic amplifications was seen, i
The performance of baseband beamforming in multi-user multiple-input multiple-output (MU-MIMO) systems has been extensively studied for simplified statistical channel models where no angular parameters are taken into account. In contrast, there is little performance analysis with ray-based models, which are more physically motivated, feature prominently in standardization and have been experimenta
In the formulation of an active enzyme enclosed in a matrix for controlled delivery, it is a challenge to achieve a high protein load and to ensure high activity of the protein. For the first time to our knowledge, we report the use of a highly swollen lipid sponge (L3) phase for encapsulation of the large active enzyme, β-galactosidase (β-gal, 238 kDa). This enzyme has large relevance for applica
Objective: The aim of this study was to evaluate whether loss of bone measured by digital X-ray radiogrammetry (DXR) of hands early in the course of rheumatoid arthritis (RA) may predict future radiographic joint damage after 1 and 2 years. Methods: A total of 166 patients with early RA, who were part of the Better Anti-Rheumatic FarmacOTherapy (BARFOT) low-dose prednisolone study, were included.

Resistivity measurements in marine environments have already been tested in Norwegian landscapes in in the detection of subsea fracture zones (Lile et al. 1994; Dalsegg, 2012). Yet, most of the produced data have been processed without taking into account the special conditions created by the presence of seawater. Similar studies outside of Norway (Tsourlos et al., 2001; Satriani et al., 2011; Ruc
