Background: Elective knee and hip arthroplasty are common surgical procedures. Improved anaesthetic and nutritional care has the potential of increasing patient satisfaction and reducing length of hospital stay (LOS). The overall aim of this thesis was to evaluate the effect of perioperative nutrition and different anaesthetic techniques on per- and postoperative outcome after elective total hip (
The male nurse is still a rare occurrence. Considerable effort has been spent on attempts at increasing the presence of women in male-dominated agentic fields and much fewer efforts have been made to increase men’s presence in female-dominated communal fields. The present study tested if the appeal of nursing for 9th grade boys (and girls) could be increased by a counter-stereotypical male role mo
Air pollution is a serious problem today, both from an environmental and from a health point of view. Especially in cities, particles smaller than 10 µm in aerodynamic diameter (PM10) can reach high concentrations. These particles are dangerous, even at low concentrations, since they are small enough to enter the lungs. In order to estimate the concentration of air pollutants, different measureme
The changing of the climate is today a problem. There are many reasons why the climate is changing but one of the biggest is the use of cars for personal transport. To reduce the emissions of climate gases many cities in Sweden are today planning for sustainable transports instead of the car. Examples of sustainable transportation is public transport and biking. Although the bike is a good vehicle
Bakgrund - Soldat är ett tungt arbete där de anställda utsätts för stor belastning i stridsövningar och träningar med tung utrustning. Utrustningen har ökat i vikt under årens lopp och kan idag väga upp emot 50 kg. Vid besvär, skador eller smärta kan uppgifter som att marschera eller utrustningsbärande bli svårt. Höga siffror har uppmätts i tidigare studier, när det gäller på smärt- och skadeprobl
This thesis aims to examine the mechanisms behind the psychiatric diagnosis resignation syndrome and why and/or how it emerged in Sweden in the early 2000s. In addition to this the thesis also aspires to explore the reasons behind why the diagnosis has fallen victim to such a large amount of criticism and suspicion. Through a literature study empirical data, consisting of primarily academic and sc
How and what we should teach children about sustainability, in relation to our current economic system, has become the cornerstone of the debate on Education for Sustainable Development (ESD). This debate takes place in conjunction with a much broader debate on the concept of sustainable development itself, where the role of economic growth is both questioned and supported, seen as either a necess
Traveller information designed to fulfil needs and expectations of individual travellers is a key factor in improving access for older people and people with disabilities to public transport. The overall aim of this thesis is to contribute to the knowledge of user and provider perspectives on the provision of traveller information for older people and people with disabilities in public transport w
Stroke is an acute neurological condition and the leading cause of disability in adult humans. Treatments for efficient recovery are not available. The most common form of stroke results from the occlusion of the middle cerebral artery, which causes loss of brain parenchyma and many types of neurons as well as astrocytes and oligodendrocytes. Neural stem cells (NSCs) could potentially be used to d
B-cells are an essential part of our adaptive immune system. A network of transcription factors together with external signals facilitate the gradual developmental progression from progenitor cells towards the B-cell fate. Several key factors participating in this network have been identified. Among these are the transcription factors E2A, HEB, EBF1 and FOXO1 as well as the IL7 signaling cascade.
ABSTRACT Background: Iodine is essential for development and growth as a constituent in thyroid hormones. Biological mechanisms for iodide uptake and concentration are very important, espe-cially as iodine is a relatively scarce element. Active iodide transport into thyroid fol-licular cells is mediated by the sodium/iodide symporter (NIS), powered by Na+/K+-ATPase. NIS is expressed also in extra
In this thesis, an inverse source reconstruction method with great potential in radome diagnostics is presented. A radome is a cover that encloses an antenna in order to protect it from environmental influences. Radome diagnostics are acquired in the design process, the delivery control, and in performance verification of repaired and newly developed radomes. A measured near or far field may indic
In human cells there are usually two copies of each chromosome, but in cancer cells abnormalities could exist. The differences consist of segments of chromosomes with an altered number of copies. There can be deletions as well as amplifications and the lengths of the segments can also vary. Localising the deviant regions is of great importance for increasing the knowledge of the disease. In this t
Parkinsons disease (PD) is a neurodegenerative disorder where dopaminergic neurons of the substantia nigra (SNc) in the mesencephalon are progressively eliminated. The ensuing loss of dopaminergic innervation of the basal ganglia manifests itself as severe motor deficits in PD patients. Clinical trials have shown that cell replacement therapy, where dopaminergic neuroblasts derived from fetal vent
It has been shown that the present interglacial has been climatically dynamic with both rapid and severe climatic fluctuations. The spatial and temporal differences of these changes are however not fully resolved. The aim of this thesis is to present a detail high resolution record of past climate changes from the central South Atlantic. Peat and lacustrine sediment sequences were retrieved from
