Fatty acids are found in many solutions treated in ultrafiltration plants, for example, in dairy products, fermentation broth, oily waste water and bleach plant effluents from pulp mills. The influence of fatty acids on the fouling of membranes is often ignored because their concentration is rather low. However, during recent years the significant influence of fatty acids on the flux reduction of
Using a special gait re-education programme, combining methods in physiotherapy with a psychological therapeutic approach to integrate the prosthesis with normal movements and to increase body awareness, the authors studied unilateral trans-femoral amputees aged 16-60 years with trauma or tumour as causes. In their service area they found 16 such current prosthetic users with at least 2 years of p
Popular Abstract in Swedish I avhandlingen redovisas undersökningar av näringsdynamiken hos fem olika lövträdsarter (ask, björk, bok, ek och lind) vilka jämförs med gran, som är ett mycket undersökt trädslag ur närings-synvinkel. Målsättningen med studierna var att klargöra de olika trädslagens näringstillstånd under likartade förhållanden, deras inverkan på och samspel med marken, samt deras näriThis thesis considers several important aspects of nutrient dynamics and allocation in adult stands of Swedish forest tree species (Quercus robur L., Tilia cordata Mill., Fraxinus excelsior L., Betula pendula Roth., Fagus sylvatica L. and Picea abies (L.) Karst) planted on the same soils. Differences between species in macro- (N, P, K, Ca, Mg, S), and micro- (B, Cu, Fe, Mn, Zn) nutrient levels in
Objective: To develop core recommendations for the learning outcomes of an undergraduate curriculum in musculoskeletal conditions for any parts of the globe. Methods: Recommendations were developed by wide consultation with experts in orthopaedics, rheumatology, osteoporosis, and rehabilitation from all parts of the world who had interest and experience in these specialties, with the support of in
BACKGROUND: New biological markers of male fecundity are needed for use in large-scale epidemiological studies. We studied the association between male inhibin B and fecundability. METHODS: Four hundred and thirty Danish couples without previous reproductive experience were followed from termination of contraception until pregnancy or for a maximum of six menstrual cycles. At enrolment we obtained
The focus of the present paper is a late posterior negative slow wave (LPN) that has frequently been reported in event-related potential (ERP) studies of memory. An overview of these studies suggests that two broad classes of experimental conditions tend to elicit this component: (a) item recognition tasks associated with enhanced action monitoring demands arising from response conflict and (b) me
PurposeTo compare the diagnostic accuracy of the Heidelberg Retina Tomograph's (HRT) Moorfields regression analysis (MRA) and glaucoma probability score (GPS) with that of subjective grading of optic disc photographs performed by ophthalmologists with varying experience of glaucoma and by ophthalmology residents.MethodsDigitized disc photographs and HRT images from 97 glaucoma patients with visual
Three process-oriented dynamic acidification models were applied to a long-term monitoring site without calibration to evaluate the influence of model structural differences on simulation. The models were simplified to share as many commonalities as possible so that the main structural differences could be investigated. The models differed in sub-models for cation exchange, organic acids and acid ani
The impeller speed, the loss-on-drying of starch, and the added amount of water significantly influenced these response variables: granule fractions of less than 0.150 mm and more than 2.00 mm; and granule median diameter. The influence of the drug concentration on the response variables was less important. All the response variables showed significant interactions. At a fixed impeller speed, the
Background: Computed tomography (CT) lung densitometry has been demonstrated to be the most sensitive and specific outcome measure for the assessment of emphysema-modifying therapy, but the optimum densitometric index has yet to be determined and targeted sampling may be more sensitive than whole lung assessment. The EXAcerbations and CT scan as Lung Endpoints (EXACTLE) trial aimed to clarify the
In species with restricted dispersal, traits may become genetically fixed leading to local adaptations. Therefore, predator avoidance in a prey species may differ between populations experiencing different predator regimes, but also between sexes within a population due to different vulnerability to predators. In this study we used male and female Gammarus pulex from two different predator regimes
I detta kapitel analyserar jag redovisande förklaringar av aktörernas agerande och observerade sekvenser där övervakning och social kontroll på institutionen återges och synliggörs av ungdomar med en annan etnisk bakgrund än den svenska. En utgångspunkt i analysen är Thomas Hylland Eriksens (1993/2000) syn på etnicitet som en pågående relationsprocess mellan aktörer. När etnifierad övervakning ocIn an evaluation of a juvenile-care project sponsored by the Swedish National Board of Institutional Care, ethnicity was identified as an important factor in treatment, staff practices, and relationships between juveniles. This study examined ethnic monitoring and social control in 15 Swedish juvenile institutions. I analysed notes from interviews and field observations. Discriminatory behaviours
Critical infrastructures provide society with services that are essential for its functioning and extensive disruptions of these give rise to large societal consequences. Vulnerability analysis gives important decision information concerning improving their ability to withstand strains. To analyze vulnerabilities in infrastructures models for estimating consequences due to failures are needed. Con
Climate denial takes many forms, ranging from outright denial of facts (literal denial), over distortion of facts (interpretive denial, e.g., denial of personal and global outcome severity), to the acknowledgement of facts but denial of their implications (implicatory denial, e.g., avoidance, denial of guilt, rationalization of own involvement). This study aimed at furthering the understanding of
Hydrodynamic forces from ships operating in sheltered, confined fairways can result in increased wave impact and sediment transport leading to loss of land and habitats. Nature-based solutions (NBS) offer the potential to mitigate ship-induced erosion and increase biodiversity and ecosystem services. The aim of this study is to evaluate the performance of NBS in a sheltered, confined fairway locat
Without evidence for an organic framework, biological and biochemical processes observed during amelogenesis provided limited information on how extracellular matrix proteins control the development of the complex fibrous architecture of human enamel. Over a decade ago, amelogenin nanoribbons were first observed from recombinant proteins during in vitro mineralization experiments in our laboratory
Introduction: Occupational health and safety management systems are widely used as a systematic approach to managing occupational health and safety. However, sometimes they are restrictive and underspecified to deal with dynamic workplace demands. Rasmussen used a model of boundaries to conceptualize this dynamic model of safety, where the space of possibilities lay within 3 boundaries and workers
Biodiversity is challenged worldwide by exploitation, global warming, changes in land use and increasing urbanization. It is hypothesized that communities in urban areas should consist primarily of generalist species with broad niches that are able to cope with novel, variable, fragmented, warmer and unpredictable environments shaped by human pressures. We surveyed moth communities in three cities
Regions with a large percentage of precipitation occurring near freezing experience high percentages (>10%) of misclassified precipitation events (rain versus snow) and necessitate efforts to improve precipitation phase determination schemes through the use of more accurate surface air temperature thresholds (Trs). Meteorological data from 169 sites in Scandinavia were used to test the applicabili
