Introduction: The aim of this study was to evaluate if magnesium deviations correlate with higher 180 day overall mortality or increased morbidity, compared to controls. Methods: We conducted a retrospective study on 5369 patients with 22,003 magnesium values treated at the Adult Intensive Care Unit at Skåne University Hospital, Lund, Sweden during 2006-2014. The patients were retrospectively divi
III-V nanowires are candidate building blocks for next generation electronic and optoelectronic platforms. Low bandgap semiconductors such as InAs and InSb are interesting because of their high electron mobility. Fine control of the structure, morphology, and composition are key to the control of their physical properties. In this work, we present how to grow catalyst-free InAs1-xSbx nanowires, wh
The need for indium droplets to initiate self-catalyzed growth of InAs nanowires has been highly debated in the last few years. Here, we report on the use of indium droplets to tune the growth direction of self-catalyzed InAs nanowires. The indium droplets are formed in situ on InAs(Sb) stems. Their position is modified to promote growth in the 〈11-2〉 or equivalent directions. We also show that in
Controlling the growth direction of nanowires is of strategic importance both for applications where nanowire arrays are contacted in parallel and for the formation of more complex nanowire networks. We report on the existence of tilted InAs nanowires on (111)B GaAs. The tilted direction is predominantly the result of a three-dimensional twinning phenomenon at the initial stages of growth, so far
Pedagogical material for children with visual impairment is often created by hand and in very small series. Although there are a lot of opportunities and there are more and more applications of how to use 3D printers in society, it's unusual that they are used systematically to create tactile material for school pupils that have a visual impairment.This report presents in a comprehensive way how t
[Context and motivation]} Internet of Things (IoT) is becoming common throughout everyday lives. However, the interaction is often different from when using e.g. computers and other smart devices. Furthermore, an IoT device is often dependent on several other systems, heavily impacting the user experience (UX). Finally, the domain is changing rapidly and is driven by technological innovation.

Background: Transient ischemic attacks (TIA) indicate an increased risk of stroke, one of the leading causes of death and disability worldwide. In order to prevent stroke, our knowledge of diagnosis, demographics, risk factors, investigations, and treatment of patients with TIA needs to be improved.Aims: The aims of this thesis were to validate data and diagnoses in the Riksstroke TIA module (Riks
BACKGROUND: Current guidelines for accessing graphs non-visually are based on giving access to underlying tabular data and reading the values one by one. When data sets are large, it becomes impossible to get an overview.OBJECTIVE: This work presents a proof-of-concept of automated audio description of data sets up to 100 data points that can be used by persons with visual impairment or persons wh
Obesity is a major health problem, and although caloric restriction and exercise are successful strategies to lose adipose tissue in obese individuals, a simultaneous decrease in skeletal muscle mass, negatively effects metabolism and muscle function. To deeper understand molecular events occurring in muscle during weight-loss, we measured the expressional change in human skeletal muscle following
1. Studies modelling heat transfer of bird plumage design suggest that insulative properties can be attributed to the density and structure of the downy layer, whereas waterproofing is the result of the outer layer, comprised of contour feathers. In this study, we test how habitat and thermal condition affect feather mass and density of body feathers (contour, semiplume and downy feathers) measure1.Studies modelling heat transfer of bird plumage design suggest that insulative properties can be attributed to the density and structure of the downy layer, whereas waterproofing is the result of the outer layer, comprised of contour feathers.

Background: The challenges of today's society call for more knowledge about how to maintain all aspects of cognitive health, such as speed/attention, memory/learning, visuospatial ability, language, executive capacity and social cognition during the life course. Main text: Medical advances have improved treatments of numerous diseases, but the cognitive implications have not been sufficiently addr
During the past decade, there has been accumulating evidence of the involvement of passive and active cell death mechanisms in both the clinical setting and in experimental models of traumatic brain injury (TBI). Traditionally, research for a treatment of TBI consists of strategies to prevent cell death using acute pharmacological therapy. However, to date, encouraging experimental work has not be
This article comprehensively reviews the lateral fluid percussion (LFP) model of traumatic brain injury (TBI) in small animal species with particular emphasis on its validity, clinical relevance and reliability. The LFP model, initially described in 1989, has become the most extensively utilized animal model of TBI (to date, 232 PubMed citations), producing both focal and diffuse (mixed) brain inj
