Datacenter utgör en central del av den digitala infrastrukturen, och efterfrågan på datacenterkapacitet ökar snabbt i takt med digitalisering, AI-utveckling och framväxten av det smarta samhället. Samtidigt står datacenterbranschen inför betydande utmaningar kopplade till ett energisystem under omställning samt en tilltagande geopolitisk osäkerhet som aktualiserat frågor om digital suveränitet och

Simuleringar för avancerad återvinning av blandat plastavfall Det globala plastavfallet ökar men återvinningsgraden följer inte med. Kemisk plaståtervinning är en lovande metod men står inför ingenjörsutmaningar kopplade till värmeöverföring och energiförbrukning. Denna studie använde beräkningsmodellen CFD-DEM för att undersöka uppvärmningen av blandat plastavfall i en kemisk återvinningsprocesGlobal plastic waste production has more than doubled in the past two decades, with plastic packaging accounting for 40% in 2019. Due to low recycling rates, pollution and limited fossil resources, increasing circularity in the plastic industry has become increasingly important. Chemical recycling through pyrolysis, unlike mechanical recycling, can treat contaminated, mixed plastic waste and incre

This thesis investigates the economic and operational consequences of price-responsive operation of a large-scale alkaline electrolyzer producing hydrogen for fossil-free steel production. A time-resolved linear optimization model was implemented in Python, describing the interaction between a 740 MW electrolyzer (37 units of 20 MW), a hydrogen storage and a constant hydrogen demand. Three operati

This thesis aims to address a dual crisis. Globally, the construction industry relies on a linear “take-make-dispose” approach and a “tabula rasa” tactic in each novel project, draining the Earth’s resources. Locally, around a half of residential buildings in Riga, Latvia, are of Soviet mass housing typology. These structures are on the verge of structural expiration, at risk of progressive collap

This thesis investigates the performance and hysteresis behaviour of building-integrated halide perovskite solar modules (BIPV PSCs) under various environmental conditions. With perovskite solar cells emerging as promising third-generation photovoltaic technology due to their high efficiency, scalability, and relatively low production costs, their integration into building surfaces offers signific

Precision medicine for complex diseases uses individual-level characteristics to improve prediction of risk, therapeutic response and prognosis. Many precision medicine studies leverage existing data types and analytic methods to reveal new insights; however, beyond oncology, there has been limited success in translating precision medicine research for complex diseases into clinical practice. Thus

Background: Climate change is emerging as a major global health crisis, escalating occupational hazards across all sectors and exacerbating social inequalities. Workers, especially those in outdoor, informal, and precarious employment are increasingly exposed to multiple hazards, leading to adverse physical and mental health outcomes, productivity losses, and premature death. Objective: This comme

Our societies are ageing, and an urban-regional perspective on these developments is urgently needed. This figure shows an uneven geography of population ageing in Sweden—in the level and pace of ageing—and calls for variegated societal adaptations across municipalities.

It has been suggested that an intensified trade war between China and the US could reduce CO2 emissions associated with exports. We develop an export-greenfield-endogenous merger model, showing that significantly increased tariffs can enable domestic firms to undertake entry-deterring acquisitions. This forces foreign firms to remain exporters, which, in turn, leads to higher emissions. Strong com

Surgery is often viewed as a lifesaving intervention, yet recovery depends just as much on what follows. The concept of individualised anaesthesia and analgesia in surgery challenges the traditional one-size-fits-all model by tailoring care to each patient's physiological and psychological profile, with the potential to improve outcomes, reduce complications, and enhance the patient experience. Ma

Background A valid definition of severe heart failure (HF) is essential for earlier identification, timely referral for advanced therapies, and to optimize clinical trial design. Objectives To assess the prevalence, prognostic performance, and 1-year outcomes associated with different definitions of severe and advanced HF (AdvHF) in patients with heart failure with reduced ejection fraction (HFrEF

Accurate three-dimensional (3D) tracking of dynamic particles in highly scattering, reacting environments like metal combustion remains challenging for conventional particle tracking velocimetry (PTV). While digital holography enables volumetric imaging, traditional holographic PTV suffers from significant depth positioning errors and velocity fluctuations due to inefficient frame-by-frame process

OBJECTIVES: To investigate utilisation patterns of different types of healthcare in a pre-pandemic and pandemic period, respectively, among children with intellectual disabilities in comparison to their age peers in the general population.STUDY DESIGN: Based on 8 years of register data, we identified 1947 children with intellectual disabilities (ID cohort) and 145 998 children from the general pop

This chapter presents a semiotic analysis of gender advertisements, introducing a novel framework that advances the Transformative Advertising Research subfield. Using a semiotic square, it categorizes gender advertisements into gender-transformative, gender-conformative, gender-nontransformative, and gender-nonconformative terms, leading to six meta-categories: gender-stereotyping, gender-neutral

Coastal dunes provide critical flood protection for low-lying coastal areas, raising the question of whether these defenses can be maintained in a future climate. Dune development is driven by interactions between sediment transport and vegetation growth. Both processes are affected by climate, notably changes in precipitation. However, tools to assess future precipitation impacts on dune developm

People's willingness to include others and their level of suspicion of those perceived to not belong are constrained by political affiliation and adherence to ideologies such as neoliberalism, Islamophobia, and ethnocentrism. In an era of heightened polarizing discourse about immigrants, the interaction between changing information and constraints can be leveraged to understand how dynamic narrati

This article presents a new way of obtaining deep explanations of environmental problems. We expose the production strategies, corporate strategies and state actions that have been taken by firms and state agencies to facilitate the geographical expansion of the wood-based commodity frontier at the expense of reindeer pastoralists among the Indigenous Sámi people. Through qualitative analysis of a

This article traces how Yazidi genocide recognition is reworked across juridico-political domains in Germany, drawing on multi-sited ethnographic fieldwork conducted between August 2025 and February 2026 and analysis of criminal judgments and asylum decisions. It argues that recognition does not operate as a stable legal achievement but takes on shifting meanings as it moves across institutional s
