The construction of quantum mechanics from electromagnetism. Theory and hydrogen atom

We reconstruct Quantum Mechanics in a way that harmonizes with classical mechanics and electromagnetism, free from mysteries or paradoxes such as the collapse of the wave function or Schrödinger’s cat. The construction is inspired by de Broglie’s and Schrödinger’s wave mechanics, while the unifying principle is Hamilton’s principle of least action, which separates natural laws from particular circ

Wealth, work, and industriousness, 1670–1860: evidence from rural Swedish probates

This article uses a new database of 1,891 probate inventories from rural southern Sweden to investigate the development of rural households’ productive capacity from the late 1600s to the 1860s. Both labourers and farmers improved their material living standards – as measured by the contents of probate inventories – but the labouring households’ ownership of means of production decreased over timeThis article uses a new database of 1,891 probate inventories from rural southern Sweden to investigate the development of rural households’ productive capacity from the late 1600s to the 1860s.

Indigenous Knowledge in Watershed Management : The Case of the Mara River Basin, Tanzania

Achieving sustainable water resource utilization requires a holistic management approach that recognizes the knowledge and values of different stakeholders through a comprehensive participation approach. This study evaluates the indigenous knowledge and technologies employed in watershed management by analyzing qualitative and quantitative data from six villages in the Mara River Basin area. Data

Everyday leisure travel : Understanding car use for social and recreational trip purposes

The aim of this thesis is to contribute to the understanding of everyday leisure travel for social and recreational trip purposes by describing and problematising car use for such trips. Leisure trips are a significant contributor to greenhouse gas emissions and reductions are needed to mitigate climate change. Technical solutions, such as electric vehicles, contribute but research has demonstrate

Vegetation runoff and sediment reduction benefits and influential factor in the Loess Plateau of China: A meta-analysis

The Loess Plateau is one of the most severely affected regions in China by soil erosion, where vegetation restoration is the principal strategy for soil and water conservation. Runoff and sediment reduction benefits (RRB and SRB) are key indicators used to evaluate the effectiveness of vegetation measures. While numerous observational and experimental studies have explored the effects of different

Roadmap for AI Policy Research

This roadmap, developed through collaborative discussions at the recent AI PolicyResearch Summit, reflects a shared vision for advancing research on responsibleAI policy and governance. It emphasizes the critical role of policy research inensuring that AI development is guided by robust evidence, ethicalconsiderations, and a commitment to sustainability and inclusivity. By prioritizingtransparency

Daylighting and lighting : Under a Nordic sky

After nearly a century in which electric lighting has dominated interior building design, there is now a shift back to using daylight as the primary ambient light source. This return is driven by considerations of energy efficiency, environmental impact, and human health. Effective daylighting in building interiors not only supports low energy consumption, but also has the potential to reconnect p

Lower circulating mitochondrial DNA and increased mitokines suggest significant mitochondrial dysfunction in systemic lupus erythematosus with renal involvement

BACKGROUND: SLE is associated with significant morbidity, especially in the case of renal involvement. Mitochondrial dysfunction plays a significant role in SLE and may be assessed by measuring mitochondrial DNA (mtDNA) and cytokines reflecting mitochondrial stress (mitokines). Circulating mtDNA is a promising biomarker in SLE and appears to be reduced in severe SLE. However, measuring circulating

Preeclampsia from a Patient Perspective

Background: Preeclampsia is a leading cause of maternal and fetal mortality. Although antenatal care can identify women at risk, limited research has explored women's experiences with preeclampsia despite itssignificant impact.Aim: This thesis aims to enhance the understanding of women's experiences with preeclampsia in order toimprove clinical care, support, and mental health outcomes.
