The Earth’s magnetic field (or geomagnetic field) has been measured for hundreds of years, starting with maritime observations from logbooks for navigation purposes to present day real-time recording by satellites. From these records, the geomagnetic field variation throughout recent time is well-understood. In order to study longer term field variations (on the scale of hundreds to thousands of y
The cellular mechanisms underlying hereditary photoreceptor degeneration are still poorly understood, a problem that is exacerbated by the enormous genetic heterogeneity of this disease group. However, the last decade has yielded a wealth of new knowledge on degenerative pathways and their diversity. Notably, a central role of cGMP-signalling has surfaced for photoreceptor cell death triggered by
Olfactory dysfunction is a common feature of both postviral upper respiratory tract infections (PV) and idiopathic Parkinson’s disease (PD). Our aim was to investigate potential differences in the connectivity of the posterior piriform cortex, a major component of the olfactory cortex, between PV and PD patients. Fifteen healthy controls (median age 66 years, 9 men), 15 PV (median age 63 years, 7
Life Cycle Assessment (LCA) studies are valuable tools for identifying high impact processes and redesigning supply chains. However, LCAs have limits, in the sense that they offer insight into relative sustainability and don't question whether a product, or its use, is sustainable in absolute terms. In this intentionally provocative paper, you join Emma, a fictional average American 15-year-old, a
In banana cultivation, a considerable amount of the production is wasted every year because of various constraints present in the post-harvest management chain. Converting green banana pulp and peels into flour could help to reduce losses and enable the food sector to keep the product for an entire year or more. In order to use green banana fruit and peel flour in the food industry as a raw ingred
The aim of this study was an in-depth investigation of the change process experienced by patients undergoing bariatric surgery. A prospective interview study was performed prior to as well as 1 and 2 years after surgery. Data analyses of the transcribed interviews were performed by means of the Grounded Theory method. A core category was identified: Wishing for deburdening through a sustainable co
The anaerobic bacterium Finegoldia magna is part of the human commensal microbiota, but is also an important opportunistic pathogen. This bacterium expresses a subtilisin-like serine-proteinase, SufA, which partially degrade the antibacterial chemokine MIG/CXCL9. Here, we show that MIG/CXCL9 is produced by human keratinocytes in response to inflammatory stimuli. In contrast to the virulent human p
The observation that neural grafts can induce dyskinesias has severely hindered the development of a transplantation therapy for Parkinson's disease (PD). We addressed the hypothesis that inflammatory responses within and around an intrastriatal graft containing dopamine neurons can trigger dyskinetic behaviors. We subjected rats to unilateral nigrostriatal lesions with 6-hydroxydopamine (6-OHDA)
Popular Abstract in Swedish Vanlig bagerijäst, Saccharomyces cerevisiae, används i storskalig etanol framställning från majs och sockerrör. Användandet av dessa råvaror för etanolproduktion konkurerar dock med framställning av spannmål för föda och djurhushållning. Den här avhandlingen har syftat till att få bagerijäst att använda sockerarten xylos, som finns i stora halter i restprodukter från skBaker’s yeast, Saccharomyces cerevisae, has been engineered to utilize the pentose sugar xylose present in lignocellulose biomass for the production of ethanol. Currently ethanol production from xylose is slow which limits the implementation of said strains in industrial production. This thesis describes the investigation of several metabolic aspects that control the rate of xylose utilization by
Aims and objectives: The research presented investigates older people’s expectations of social assistive robots and telehealthcare systems. Methods: The empirical studies presented are based on fieldwork carried out before social assistive robots and a telehealthcare system were introduced into the domestic environment of older people. The research draws upon participatory design to explore older
Wind power is seen by many observers as an important part of the transition to a sustainable energy system, since it does not contribute to the environmental problems connected with dominating energy forms such as fossil fuel, nuclear power and large-scale hydro power. At the same time wind power has some characteristics that makes it a special challenge for land use planning. In Sweden, where win
During the stress response adrenal medullary chromaffin cells release catecholamines to the bloodstream. Voltage-activated calcium channels present in the cell membrane play a crucial role in this process. Although the electrophysiological and pharmacological properties of chromaffin cell calcium channels have been studied in detail, the molecular composition of these channels has not been defined
A new spectrometer for studying photoinduced fragmentation has been designed and commissioned. The instrument produces a detailed view of the energy and angular emission of fragments, which in the case of small molecules can be related to their geometry at the moment of dissociation. The spectral profiles for single, double and triple ion coincidences are analyzed in terms of molecular alignment,
The issue of an increasing number of people globally that are adopting unsustainable lifestyles is important because we are destroying the earth’s resources at an accelerating rate. In particular, the pattern of major increasing environmental impact caused by modern food production has the potential to become an important sector for climate change mitigation, but despite the myriad of guides avai
The purpose of this study was to describe and analyse how case-workers manage the mental and social needs within elderly care. Many elderly suffer from mental illness, depression och loneliness. The study was conducted by qualitative semistructured interviews with case-workers through a targeted selection process. The study showed that physical needs are easier to manage and carry out rather than
Mammals express thirteen different isoforms of the membrane-bound water channel aquaporin in a tissue-dependent manner. From a medical point of view, two of the most studied isoforms are aquaporin (AQP0), also known as major intrinsic protein and aquaporin 2 (AQP2). AQP0 is exclusively expressed in the mammalian eye lens and responsible for the transport of water across lens fiber cell membranes t
This study contributes to the understanding of supply-side Training for Employment (TE) for the unemployed youth. The rates of youth unemployment in the European Unions have been matter of concern in the political agenda in the latest years, thus the European Employment Strategy has placed a particular emphasis in addressing this issue. As a result of the 2008 economic recession, the rates of yout
This essay concerns ring brooches in Lund from late Viking age and the Middle ages, 10th to 16th century. The purpose is first and foremost to typologize the ring brooches and to investigate the similarities and differences between them. Moreover, this essay investigate why the brooches change in form and decoration over the period of time and what these changes can disclose about Lund and how it
Speed, portability and quality. These are all attributes that manufacturers are striving to achieve. The demand for speed is making wireless frequencies increase with a steady pace. The demand for portability is filling the world with high speed wireless devices that are expecting their data fast and without errors. The demand for quality is met by making efficient ways of testing products before
Denna uppsats behandlar tvångsinlösen av minoritetsaktier i onoterade bolag i syfte att klargöra rättsläget genom att analysera gällande rätt. Tvångsinlösen av minoritetsaktier möjliggörs när en majoritetsaktie-ägare äger nio tiondelar av aktierna i ett bolag. Majoritetsaktieägaren kan då lösa in en eller flera minoritetsaktieägares aktier i bolaget. Lösenbeloppet blir ofta föremål för tvist, särThis essay answers a series of questions regarding the process of valuation of shares in unlisted limited companies when subject to a squeeze-out. The purpose of the thesis is to clarify the legal position by analysing the law. A squeeze-out is enabled when a shareholder owns more than nine tenths of the shares in a company. The majority shareholder may then choose to force the minority sharehold
