Branched-Chain Amino Acid Supplementation Enhances Substrate Metabolism, Exercise Efficiency and Reduces Post-Exercise Fatigue in Active Young Males

Background: Branched-chain amino acids (BCAAs, isoleucine, leucine, and valine) are commonly applied to promote muscle protein synthesis. However, the effects of BCAAs on exercise-induced substrate metabolism, performance and post-exercise fatigue during endurance exercise remain unclear. Methods: In a double-blind cross-over design, eleven active males completed 1 h of constant load exercise (CLE

Influence of highly flexible di(biphenyl)ethane units on the properties of poly(arylene piperidinium) anion exchange membranes

Introducing angled arene units or short flexible alkyl segments into rigid aromatic hetero-atom-free polymer backbones is an efficient strategy to improve the performance of anion exchange membranes (AEM)s. So far, only very few monomers have been presented that increase backbone flexibility in polymers prepared by polyhydroxyalkylations, often with limited reactivity and polymerizability. Here, w

Performance of a full-scale anaerobic UASB digester treating blackwater from an urban city district in Helsingborg, Sweden

The growing global population has increased the demand for circular sanitation solutions that enhance energy and nutrient recovery. Anaerobic digestion (AD) of blackwater (BW) offers a promising solution, but its application in full-scale UASB reactors remains unexplored. This study evaluated the performance of a full-scale UASB (50 m3) treating BW collected from a new city district (Oceanhamnen)

Closed-loop upcycling of sewage sludge products into sp2-C-rich electrodes for pollutant oxidation : tracking mineralization by 14C-labeling

To address the need for sustainable wastewater treatment, we developed sp2‑carbon-rich, hierarchically porous electrodes by upcycling sewage sludge ash (SSA) and biochar (CB) using a hybrid 3D printing and microwave plasma-enhanced chemical vapor deposition (MPECVD) approach. The CB-containing electrode exhibited a 260-fold increase in BET surface area (0.15 to 40.6 m2 g−1), but the lowest electro

Time-resolved spectroscopy of two-dimensional systems : from the conventional method to a novel cavity-enhanced solution

The work presented in this dissertation is dedicated to the characterization of the excited state dynamics of thin films through time-resolved spectroscopy, with emphasis on developing a methodology that is able to resolve weak transient absorption signals from optically thin films. With this aim, the conventional transient absorption spectroscopy method is first utilized to characterize semicondu

Electrophoretic mobilities of neutral analytes and electroosmotic flow markers in aqueous solutions of Hofmeister salts

Small neutral organic compounds have traditionally the role of EOF markers in electrophoresis, as they are expected to have zero electrophoretic mobility in external electric fields. The BGE contains, however, ions that have unequal affinities to the neutral molecules, which in turn results in their mobilization. In this study we focused on two EOF markers-thiourea and DMSO, as well as on N-methyl

The association between non-motor symptoms and cost in Parkinson’s disease

Background: Parkinson’s disease (PD) is a neurodegenerative disorder associated with substantial costs that escalate as the disease progresses. Previous research has explored the relationship between disease progression, motor symptoms, and the economic burden of PD. However, there is a lack of studies focusing on the relationship between costs and non-motor symptoms (NMS). Objective: To examine t

Reversible semimetal-semiconductor phase transition in CVD-grown monolayer MoTe2

Monolayer molybdenum ditelluride (MoTe2) attracted intensive scientific interest due to the small energy difference between its semiconducting (1H) and semimetallic (1T’) phases. Understanding MoTe2 polymorphism phenomena and developing pathways to induce reversible phase transformations is of great scientific and practical importance to develop semiconductor-semimetal phase change devices. In thi

Creating B-Spline Representations of Tree Stems from LiDAR Point Cloud Data

The development of decision-assisting tools for use in forestry operations has the potential to improve the adherence to forest management best practices, which could benefit biodiversity and increase the economic efficiency of the forest industry. NFA Forestry Automation AB is developing a system that leverages information about the forest environment extracted from data collected with harvester-

Effectuation and Causation Decision-Making in Entrepreneurship Students: A Qualitative Study on Decision-Making in Venture Creation Programs (VCPs)

Background Venture Creation Programs (VCPs) provide a unique experiential learning setting in which real-world uncertainty, emotional dynamics, and iterative learning cycles shape entrepreneurial decision-making. Research Gap While prior research has established the importance of effectuation and causation in entrepreneurship, less is known about how students apply these decision-making logics wi

Navigating Through Networks: Social Capital and Agency Theory in Business Angels' Investment Processes

This study explores how business angels in southern Sweden use social connections and trust to find and assess potential investments. Business angels often rely on their network for finding investment opportunities, and the process can vary from one cultural context to another. Most existing research on the business angels’ investment process lacks a focus on the relational and informal mechanisms

Introduction : Political Theology in the Spirit of Populism – Methods and Metaphors

Studies scrutinizing the significance of religion for populism are still scarce, but one metaphor has been adopted across almost all of them—the metaphor of the hijacked faith. This chapter sketches the nexus between metaphor and method in the study of populism, before it introduces the contributions to this compilation. Ulrich Schmiedel suggest that there are structural similarities between popul

Health and Health-Related Connected Objects : Regulatory Intersections, Grey Zones and Blind Spots

The present paper explores legal issues concerning connected objects used for health or health-related purposes and their corresponding usage of health and health-related data. It focuses on a patient/healthcare-user-centred perspective and researches the EU legal framework for health data and health-related data. Arguing that the legal framework, as recently complemented with the European Health

Sluta samarbeta med universitet som är delaktiga i krigsbrott

Bryt tystnaden och värna den akademiska friheten. Vi uppmanar ledare för svenska lärosäten att agera enligt sina egna etiska principer och ta ställning mot folkmordshandlingar i Gaza och angrepp på det palestinska utbildningssystemet, att försvara studenters rätt till fredliga protester och att avsluta samarbeten med universitet som är delaktiga i krigsbrott, skriver åtta forskare och akademiska l

Navigating the Moral Landscape of Foster Care: : The Risk of Blame and Suspicion in Paid Parenthood

Foster care provides a family‐like upbringing for children who cannot stay with their biological parents for various reasons. While the practice of paying foster parents is not questioned, the level of the fee and how it is spent (or not spent) are morally charged matters. Foster parents’ motives may be questioned by the media, neighbors, or social workers, who may suspect financial gain. Although

Persistent Value Relations : Varieties and Explanation

Some things hold value in a way that makes them superior to others, regardless of how much of the lesser values are involved. Philosophers have often found this idea of persistent betterness to be puzzling. In this paper, we argue that superiority belongs to a broader class of persistent value relations, including stubborn varieties of equality and parity, each of which will be exemplified and ana
