Precise geochronology, combined with paleomagnetism on mafic intrusions, provides first-order information for paleoreconstruction of crustal blocks, revealing the history of supercontinental formation and break-up. These techniques are used here to further constrain the apparent polar wander path of the Kaapvaal Craton across the Neoarchean-Paleoproterozoic boundary. U-Pb baddeleyite ages of 2441

An important issue in clinical neural grafting is whether a second instriatial allograft can survive well in a patient who has received an allograft before. In this study, the survival, immunogenicity and function of intrastriatal grafts of allogeneic or syngeneic embryonic dopamine-rich tissue in rats which had previously received either an intrastriatal allo- or syn-graft or sham injections were

Whenever a material object is selected to represent a physically absent, but emotionally present referent, such as a religious figure or a deceased relative, we have a complex representation situation that involves what we could tentatively label “transgressive cognitive acts”. A transgressive cognitive act is here meant to involve a part that is experienced as present, and as having an effect, bu

Patients suffering from the progressive neurodegenerative disease Friedreich’s ataxia have reduced expression levels of the protein frataxin. Three major isoforms of human frataxin have been identified, FXN42-210, FXN56-210 and FXN81-210, of which FXN81-210 is considered to be the mature form. Both long forms, FXN42-210 and FXN56-210, have been shown to spontaneously form oligomeric particles stab

Jordbruksmodernisering har dramatiskt ökat tillgången till mat på global nivå, men till ett högt pris för miljön. Idag efterlyser många ett ’paradigmskifte’ i jordbruket, även flera stora mainstream-institutioner. Med ett skifte till vad? Under senare år har det synts en ökande tilltro till agroekologi, ett alternativ som syftar till att förstå och bedriva jordbruk som komplexa agroekosystem. FrånAgricultural modernization has massively increased global food supply, but at a high environmental cost. Today many are calling for an agricultural ‘paradigm shift’, including several mainstream institutions. But to what? In recent years, agroecology has gained credence as an alternative approach that seeks to understand and manage farms as complex agroecosystems. From a development perspective, i

In the last decades, the frequency and intensity of cyanobacterial blooms have been of increasing concern. They have become a direct threat to the drinking water supply by clogging filters, bringing odour and unpleasant taste to the treated water and worst of all, causing elevated cyanotoxins, which can be difficult to remove, yet lead to severe health issues. This thesis aims to present a compreh

Agricultural intensification and associated loss of high-quality habitats are key drivers of insect pollinator declines. With the aim of decreasing the environmental impact of agriculture, the 2014 EU Common Agricultural Policy (CAP) defined a set of habitat and landscape features (Ecological Focus Areas: EFAs) farmers could select from as a requirement to receive basic farm payments. To inform th

Background: Breast cancer arises within specific regions in the human breast referred to as the terminal duct lobular units (TDLUs). These are relatively dynamic structures characterized by sex hormone driven cyclic epithelial turnover. TDLUs consist of unique parenchymal entities embedded within a fibroblast-rich lobular stroma. Here, we established and characterized a new human breast lobular fi

In situ CO2 and CO measurements from five Integrated Carbon Observation System (ICOS) atmosphere stations have been analysed together with footprint model runs from the regional Stochastic Time-Inverted Lagrangian Transport (STILT) model to develop a dedicated strategy for flask sampling with an automated sampler. Flask sampling in ICOS has three different purposes, namely (1) to provide an indepe

Consumer research has a long tradition of examining the limits of consumer society (e.g. Schor & Holt, 2000). Overconsumption refers to a harmful and excessive type of consumption practice, which is typical of contemporary consumerism (Kjellberg, 2008). In the past, overconsumption was used synonymously with more theoretical concept such as hyper-consumption (Kilbourne et al., 1997) and afflue

Elevated molybdenum (Mo) contents in organic-rich sediments are indicative of deposition from an anoxic and sulfide-rich (euxinic) water-column. This can be used for tracing past euxinic conditions in ancient oceans from sedimentary archives. Conventional analytical detection of elevated molybdenum levels is, however, expensive and cannot be directly performed in the field. Here, we show that hand

In complex biological systems (e.g. gels, cross-linked proteins and biological tissues), the longitudinal spin relaxation of water protons is primarily induced by exchange-mediated orientational randomization (EMOR) of intra- and intermolecular magnetic dipole-dipole couplings. The chemical exchange processes that dominate the magnetic relaxation dispersion (MRD) typically occur on a time scale of

Crime reality television is a significant origin story in understanding reality entertainment. In the 1980s, crime reality television captured the public’s imagination with cold cases, ongoing criminal investigations, surveillance feeds, and live appeals to the public for information to catch criminals. Early crime reality television borrowed from other factual genres, including news reportage, cr

The polynuclear compounds containing anisotropic metal ions often exhibit efficient barriers for blocking of magnetization at fairly arbitrary geometries. However, at variance with mononuclear complexes, which usually become single-molecule magnets (SMM) under the sole requirement of a highly axial crystal field at the metal ion, the factors influencing the SMM behavior in polynuclear complexes, e

We evaluate the capability of the global atmospheric transport model TM5 to simulate the boundary layer dynamics and associated variability of trace gases close to the surface, using radon (222Rn). Focusing on the European scale, we compare the boundary layer height (BLH) in the TM5 model with observations from the National Oceanic and Atmospheric Admnistration (NOAA) Integrated Global Radiosonde

Introduction: It has previously been found that strongly predicted words can be pre-activated in constraining contexts (e.g. DeLong, Urbach & Kutas, 2005). Furthermore, it has been suggested that an anticipated continuation from one syllable to another can be pre-activated before it is present in the input (Roll, Söderström, Mannfolk, Shtyrov, Johansson, van Westen & Horne, 2015). We descr

The aim of this project has been to study timber house manufacturers and provide guidance to those who aim to increase efficiency through the adaption of product modeling and eventually configuration. The findings in this report are based on a series of case studies within the abovementioned industry, which serves as a basis for the analysis and recommendations given. The Swedish timber house man

To study the role of serum testosterone (T), estradiol (E(2)), and SHBG as regulators of peak bone mass and bone turnover rate in males, a cross-sectional study with data on lifestyle factors collected retrospectively was performed in 204 young Finnish men, 18.3-20.6 yr old. One hundred fifty-four men were recruits of the Finnish Army, and 50 were men of similar age who had postponed their militar
