When Swedish wastewater treatment plants were rebuilt to include enhanced nitrogen removal, anaerobic ammonium oxidation (anammox) was far from being a mature technology. During the 2000s, the process has been introduced into sludge liquor treatment worldwide. The step to introduce anammox in the mainstream is decreasing, but lab- and pilot-scale studies on real municipal wastewater are yet lackin
Popular Abstract in Swedish Det övergripande syftet med denna avhandling var utforska de allra äldstas upplevelser av delaktighet och självständighet med speciellt fokus på hemmet och närmsta omgivningen. Dagens debatt om åldrandet handlar mestadels om kvaliten i vård och omsorg, dess kostnader men också om bristande omsorg. Även boendefrågor debatteras, men då är det oftast bristen på s k särskiThe current trend in Sweden is to support older people to remain living in their own homes as long as possible. Older people spend much of their daily life within the home and neighbourhood environment. It is well known that participation and independence is important in experiencing well being in old age. Thus from a health-promotion perspective it is interesting to uncover aspects within the hom
Northern Europe was capped by ice during Weichsel (Wurm), the maximum of which occurred approximately 18,000 years before present. When in the latter part of the 19(th) century the view of an all-devastating land ice (the tabula rasa hypothesis) was generally adopted by natural scientists, plant biogeographers used a simple model predicting a post-glacial, northwards re-migration of species in con
Popular Abstract in Swedish Protontransport är en fundamental process som finns i många naturliga system, liksom i många tekniska applikationer, såsom bränsleceller, smarta fönster och olika typer av sensorer. Bränslecellsteknologi anses vara miljövänlig eftersom bränsleceller inte begränsas av Carnot-cykeln och omvandlar effektivt kemisk energi till elektrisk energi som sedan kan användas till atProton transport is a fundamental process that can be found in many systems in nature, as well as in technical devices, such as fuel cells, electrochromic devices and various types of sensors. Fuel cell technology is considered as environmentally friendly because fuel cells are not limited by the Carnot cycle, and efficiently converts chemical energy into electrical energy which can be used for po
Developments in body theory have had a strong impact on archaeology in recent years, but the concept of the body has tended to remain abstract. The term “body” is often used as a synonym for self or person, and the remains of bodies and body parts have often been approached theoretically as signs or symbols. While this has emphasized the importance of the body as a cultural construct and a social
Popular Abstract in Swedish Vattengråsuggan Asellus aquaticus är ett väldigt vanligt ryggradslöst djur i många typer av svenska vatten. Den kan bli över 10 mm stor och äter allt från dött organiskt material till levande alger och växter. Färgen hos gråsuggan kan variera mycket mellan olika miljöer. Den är oftast mörk men kan även vara nästan vit i underjordiska grottpopulationer. Jag har studerat Pigmentation in the freshwater isopod Asellus aquaticus differed between two habitats. Asellus were lighter pigmented in stands of submerged stonewort vegetation, than in nearby reed stands. Moreover, Asellus pigmentation became lighter with time in recently established stonewort stands. Diet or pigment adjustment had minor influence on pigmentation and mating was random with respect to pigmentati
Characterizing population fluctuations and their causes is a major theme in population ecology. The debate is on the relative merits of density-dependent and density-independent effects. One paradigm (revived by the research on global warming and its relation to long-term population data) states that fluctuations in population densities can often be accounted for by external noise. Several empiric
An evaluation has been made of the capability of rapeseed oil to dissolve polycyclic aromatic hydrocarbon (PAH) crystals in a biphasic system and of its capability to extract PAHs from polluted soil in a two-liquid-phase (TLP) slurry system. Up to 220 g l(-1) of the crystalline hydrocarbons could be dissolved in the organic phase, indicating oil/water-partitioning coefficients of 10(5). When soil
Since emf measurements with amalgam electrodes have been used, in most studies of the stabilities of complexes between soft metal acceptors and halide ions a series of investigations of the kinetics of electrode reactions were accomplished with halide systems of metal ions in the Groups 11 and 12 in aqueous and/or DMSO solutions. The aim was to establish which complexes contribute to the exchange
A single institution series of 81 consecutive, cytogenetically analyzed, diffuse large B-cell lymphomas (DLBL), the majority of which treated with anthracycline-containing combination chemotherapy, were reviewed retrospectively to investigate whether the karyotypic pattern or certain abnormalities correlate with survival. Clonal chromosome changes were found in 79 of the 81 cases. The prognostic i
OBJECTIVE: To study the pharmacodynamics of amoxicillin/clavulanic acid against different strains of Haemophilus influenzae in an in vitro kinetic model. The concentrations used corresponded to human serum levels obtained after 875 mg amoxicillin/clavulanic acid given b.i.d., 500/125 mg amoxicillin/clavulanic acid given t.i.d. and those obtained with a pharmacokinetically enhanced formulation cont
We consider the problem of how to schedule t similar and independent tasks to be performed in a synchronous distributed system of p stations communicating via multiple-access channels. Stations are prone to crashes whose patterns of occurrence are specified by adversarial models. Work, defined as the number of the available processor steps, is the complexity measure. We consider only reliable algo
The influence of lipid concentration on hydrolysis and biomethanation of a lipid-rich (triolein) model waste was evaluated in batch. The effect of increasing the concentration of lipid from 5% to 47% (w/w), based on chemical oxygen demand (COD), was investigated. The methane recovery observed was above 93% for all tests. An initial lag phase of approximately 6-10 days was observed for all tests. T
This study describes the evaluation and characterization of a self-nanoemulsifying drug delivery system (SNEDDS) consisting of a nonionic surfactant (Cremophor RH40), a mixture of long chain mono-, di-, and triacylglycerides (Maisine 35-1 and Sesame oil) and ethanol. Compositions containing 10% (w/w) ethanol, 40%-60% (w/w) lipid content, and 30%-50% (w/w) Cremophor RH40 were identified as pharmace
When a mobile station moves along a trajectory, it will see different parts of the same scatterers or scatterer groups during its movement. In this paper, we present a new method to identify such physical clusters of scatterers, and the corresponding groups of multipath components (MPCs) interacting with those clusters, from measurements of channel impulse responses. The method is based on identif
While research on the design of heterogeneous concurrent systems has a long and rich history, a unified design methodology and tool support has not emerged so far, and thus the creation of such systems remains a difficult, time-consuming and error-prone process. The absence of principled support for system evaluation and optimization at high abstraction levels makes the quality of the resulting im
Abstract in Undetermined Distractors and environmental noise has long been regarded as detrimental for cognitive processing. In particular children with Attention Deficit Hyperactivity Disorder (ADHD) are extremely sensitive to distraction from task irrelevant stimuli. However, recently it has been shown that exposure to auditory white noise facilitated cognitive performance in ADHD children where
The Hipparcos mission (1989-1993) resulted in the first space-based stellar catalogue including measurements of positions, parallaxes and annual proper motions accurate to about one milli-arcsecond. More space astrometry missions will follow in the near future. The ultra-small Japanese mission Nano-JASMINE (launch in late 2013) will determine positions and annual proper motions with some milli-arc
Feminists, like many others, want to make a difference. They are interested in social change. They are especially interested in the ways this concerns the position of women in our societies. In order to accomplish this, the different actors within the women’s movements of Europe must be present in the political arenas where decisions are made. This concerns white indigenous women, as well as Black
