A transition to a more sustainable energy system is called for, and to realise such a transition governments around the world have introduced various research programmes and policy instruments. In this paper, we elaborate on how the transition of the energy system could be reinforced through evaluation of research programmes and policy instruments, focusing on energy efficiency in buildings. We ar
Massive expansion of erythroid progenitor cells is essential for surviving anemic stress. Research towards understanding this critical process, referred to as stress-erythropoiesis, has been hampered due to the lack of specific marker-combinations enabling analysis of the distinct stress-progenitor cells capable of providing radioprotection and enhanced red blood cell production. Here we present a
Objectives: Association between socio-demographic factors and dementia risk is studied in general but not for atrial fibrillation (AF) patients. Methods: We studied AF patients ≥ 45 years in Sweden 1998–2012 (n = 537,513) using the Total Population Register for socio-demographic factors, the Swedish Cause of Death Register, and the National Patient Register (NPR) for incident dementia. Cox regress
There has been much recent interest in nuclear fission, due in part to a new appreciation of its relevance to astrophysics, stability of superheavy elements, and fundamental theory of neutrino interactions. At the same time, there have been important developments on a conceptual and computational level for the theory. The promising new theoretical avenues were the subject of a workshop held at the
Gasoline Compression Ignition research has shown that it can provide diesel like engine efficiency while maintaining gasoline like exhaust emissions. While research has shown that lower octane fuels might be good for that, they are also not available now. A good compromise for that would be the use of higher octane gasoline which is available in most places. For this study, experiments were perfor
U-Pb geochronology on baddeleyite is a powerful technique that can be applied effectively to chronostratigraphy. In southern Africa, the Kaapvaal Craton hosts a well-preserved Mesoarchean to Paleoproterozoic geological record, including the Neoarchean Ventersdorp Supergroup. It overlies the Witwatersrand Supergroup and its world-class gold deposits. The Ventersdorp Supergroup comprises the Klipriv
Resilience, or the capacity to bounce back from adversity strengthened and more resourceful, can be considered an important quality of virtual teams in the contemporary working world. A team is the basic organizational unit many modern firms are composed of—and, the virtual ones are those conducting teamwork over distance using a combination of telecommunications and information technologies to ac
The Common Agricultural Policy (CAP) is the guiding policy for agriculture and the largest single budget item in the European Union (EU). Agriculture is essential to meet the Sustainable Development Goals (SDGs), but the CAP's contribution to do so is uncertain. We analyzed the distribution of €59.4 billion of 2015 CAP payments and show that current CAP spending exacerbates income inequality withi
Background: Hypoxic-ischaemic encephalopathy (HIE) is a leading cause of mortality and long-term neurological sequelae, affecting thousands of children worldwide. Current therapies to treat HIE are limited to cooling. Stem cell-based therapies offer a potential therapeutic approach to repair or regenerate injured brain tissue. These preclinical findings have now culminated in ongoing human neonata
For all involved in astronomy, the importance of monitoring and determining astrophysical magnetic-field strengths is clear. It is also a well-known fact that the corona magnetic fields play an important part in the origin of solar flares and the variations of space weather. However, after many years of solar corona studies, there is still no direct and continuous way to measure and monitor the so
Importance: Adjuvant imatinib is associated with improved recurrence-free survival (RFS) when administered after surgery to patients with operable gastrointestinal stromal tumor (GIST), but its influence on overall survival (OS) has remained uncertain. Objective: To evaluate the effect of adjuvant imatinib on OS of patients who have a high estimated risk for GIST recurrence after macroscopically c
Importance: Information about how risk for bipolar disorder is transmitted across generations and how parental risk for bipolar disorder relates to their children's risk for schizophrenia and major depression is limited. Objective: To evaluate the sources of parent-offspring transmission of bipolar disorder and its familial cross-generational association with schizophrenia and major depression. De
Droplet-based microfluidics is a widely used technology in various chemical and biological applications. Droplet formation is an essential part of droplet-based microfluidics. This work applied and summarized a combination of techniques for speeding up computational fluid dynamics (CFD) simulations based on the Volume of Fluid method for the droplet generation process. To demonstrate the efficienc
This artistic research PhD project challenges classical music performance culture through a series of experimental collaborative projects. My particular interest lies in how this culture shapes the psychological experience of performance from the perspective of the individual musician. The project’s aims can be further defined through the following research questions: a) How can I better understan
This work experimentally tests and numerically investigates the heat transfer augmentation, the flow characteristics and the overall thermal performance of truncated ribs in a rectangular channel with an aspect ratio of 1:4 designed by using the fractal theory. The liquid crystal thermography (LCT) method in steady-state is adopted and the three-dimensional CFD numerical simulations with an establ
The present work concentrates on perforated 90° ribs to improve the thermal performances in a rectangular cooling channel with an aspect ratio of 4:1. Three different types of perforated ribbed channels are designed and compared. Steady-state Liquid Crystal Thermography (LCT) is employed to measure surface temperature and derive heat transfer coefficients over the ribbed surfaces in the tested cha
T1-magnetic resonance imaging (MRI) studies report early atrophy in the left anterior temporal lobe, especially the perirhinal cortex, in semantic variant primary progressive aphasia (svPPA). Improved segmentation protocols using high-resolution T2-MRI have enabled fine-grained medial temporal lobe (MTL) subregional measurements, which may provide novel information on the atrophy pattern and disea
Solar-driven reduction of water to produce hydrogen is one of the most promising ways to develop sustainable cleanenergy for the future. The challenge in photocatalytic hydrogen evolution research is to design inexpensive catalystsand construct efficient hydrogen production systems. In this thesis, different photocatalytic hydrogen productionsystems consisting of catalysts, photosensitizers and sa
