The optical properties of the crystalline lenses were studied in a variety of large predatory teleosts (bony fishes) that forage in the open ocean, some of them at considerable depths. We found the first fish lenses that are free of measurable longitudinal spherical aberration, i.e., are perfectly monofocal, in contrast to the multifocal lenses that are typical for smaller fishes living close to t
The long-range, pheromone-mediated, flight behaviour of male moths under natural and mating disruption conditions was monitored by means of harmonic radar. Individual male turnip moths, Agrotis segetum (Denis & Schiffermüller) (Lepidoptera: Noctuidae), tagged with radar transponders, were released and tracked in plots with or without disruptive doses of sex pheromone. In addition, male attract
Background: An emergency department (ED) should offer timely care for acutely ill or injured persons that require the attention of specialized nurses and physicians. This study was aimed at exploring what is actually going on at an ED. Methods: Qualitative data was collected 2009 to 2011 at one Swedish ED (ED1) with 53.000 yearly visits serving a population of 251.000. Constant comparative analysi
Although several studies have examined how honeybees gauge and report the distance and direction of a food source to their nestmates, relatively little is known about how this information is combined to obtain a representation of the position of the food source. In this study we manipulate the amount of celestial compass information available to the bee during flight, and analyse the encoding of s
Syfte: Studien undersöker vilken information klassificering i subformer av Lindriga kognitiva symptom (MCS) och depressions- och ångestsymptom tillför den diagnostiska prediktionen av Alzheimers sjukdom (AS) för patienter med MCS. Metod: Patienterna (N = 417) var mellan 60 och 80 år och hade subjektiva och/ eller objektiva lindriga kognitiva symptom, men uppfyllde inte diagnoskriterier för demenssAims: The study investigates what information classification of Mild Cognitive Symptoms (MCS) subtype and symptoms of depression and anxiety add to the diagnostic prediction of Alzheimer's disease (AD) for MCS-patients. Method: Patients (N = 417), ranging between 60 and 80 years old, had subjective and/ or objective mild cognitive symptoms, but did not meet diagnostic criteria for dementia at
To many families and children, playground visits are an important part of the daily life. Playing there can offer benefits like physical activity as well as practicing skills such as social interaction or creative ability. The purpose of the master thesis presented in this report, was to develop a new product line with playground equipment for HAGS Aneby AB. The playground equipment should allow
We present the first study of the year-round distribution, activity patterns, and habitat use of one of New Zealand’s most common seabirds, the fluttering shearwater (Puffinus gavia). Seven individuals from Burgess Island and one individual from Long Island were successfully tracked with combined light-saltwater immersion loggers for one to three years. Our tracking data confirms that fluttering s
Introduction: Propolis is a sticky substance produced by honeybees from plant resins collected from locally growing vegetation. Its chemical composition varies depending on the plant species visited by the bees. Contact dermatitis is commonly reported following exposure to cosmetics containing propolis or following the intake of food supplements. Objectives: To investigate the prevalence of contac
Each spring, billions of Bogong moths escape hot conditions across southeast Australia by migrating up to 1,000 km to a place that they have never previously visited—a limited number of cool caves in the Australian Alps, historically used for aestivating over summer1,2. At the beginning of autumn, the same individuals make a return migration to their breeding grounds to reproduce and die. Here we
The causal role of pollinators in driving the divergence of plant traits is a fundamental tenet of angiosperm evolution, providing hallmark examples of evolution in response to natural selection. However, it remains unclear how geographic variation in pollinator assemblages relates to the divergence of pollination traits in pollination-generalized plants. We characterized pollinator assemblages th
UNLABELLED: Intraoperative radiographic guidance has traditionally been utilized in orthopedic surgery through 2-D navigation with the C-arm and recently with 3-D navigation with the O-arm. The aim of this study was to describe the outcome of surgical treatment of spinal osteoblastoma and osteoid osteoma with the utilization of the O-arm and conventional C-arm guidance. This is a retrospective coh
Twenty years of methodological development, empirical research and practice application have resulted in an updated version of the Housing Enabler instrument and a screening version. The methodology rests on Lawton’s and Nahemow’s ecological model, with accessibility defined as the relationship between the individual’s functional capacity and the demands of the physical environment. The complete i
While color vision and spatial resolution have been studied in many bird species, less is known about the temporal aspects of bird vision. High temporal resolution has been described in three species of passerines but it is unknown whether this is specific to passerines, to small actively flying birds, to insectivores or to birds living in bright habitats. Temporal resolution of vision is commonly
Background: Health-related quality of life (HRQoL) is poor in patients with persistent diabetic foot ulcers and poor HRQoL predicts worse outcomes in these patients. Amputation is often considered a treatment failure, which is why conservative treatment is generally preferred over amputation. However, it is unclear whether minor amputation negatively affects HRQoL compared with conservative treatm
Blowflies are the primary facultative agent in causing myiasis of domestic sheep in the whole world and, at the same time, it is an important tool for forensic medicine. Surprisingly, and in contrast to its importance, almost no data regarding the embryology and molecular markers are known for this insect. In this report, we present a detailed description of the blowfly Lucilia sericata embryogene
Background Patients with inflammatory bowel disease (IBD) often complain of fatigue. Aim To investigate the prevalence and characteristics of fatigue among IBD out-patients in Scandinavia and to provide normative values for fatigue in IBD patients. Methods A cross-sectional study was conducted on 425 IBD patients from six out-patient centres in Denmark, Norway and Sweden. Fatigue was measured usin
Knowledge mediation and power distribution are common subjects in everyday life. In school knowledge and learning are keywords for the activity, while on the other hand industries have production and benefits as major subjects. Despite these differences between school and industry they both can be discribed as learning organizations. This could be made to facilitate a gaining of knowledge in effor
Background: Most commonly, volume measurements are used to evaluate the effect of lymphedema treatment, but as the accumulation of lymph fluid can be local, this method may not always be the best. Tissue dielectric constant (TDC) can be applied to identify local lymphedema changes, but has not been used before when evaluating treatment in mild arm lymphedema. Thus, the overall aim of this study wa
Mattias Risberg is an organist, synthesizer player, pianist and composer who was living in Uppsala when we made this collaboration. We visited two churches several times outside of Uppsala, Vittinge Congregational Church in Vittinge and North Congregational Church in Tärnsjö, during the summer and fall of 2015, where we recorded three sessions of purely improvised music. We also had many conversat
