Underhållsverksamheten på Roslagståg kan ses som reaktiv och reparationsorienterad. För att kunna ta nästa steg i utvecklingen av ett mer proaktivt och funktionssäkerhetsorienterat underhåll bör följande åtgärder genomföras: Den övergripande målsättningen med underhållet bör förändras till att fokusera på ökad driftsäkerhet och ökad kostnadseffektivitet. Detta för att skapa långsiktighet och belys

With population aging, more adults across Europe face competing demands of working for pay and caring for elderly family members. Associated tradeoffs are expected to be negative, gendered, and vary across contexts with different levels of gender equality, public support for eldercare, and work-family balance. Using SHARE data from 2004–20, this study investigates how unpaid caregiving to independ
Developing high-performance, low-cost oxygen evolution reaction (OER) catalysts is crucial for advancing anion exchange membrane water electrolysis (AEMWE) in large-scale industrial green hydrogen production. Herein, We report a glucose-mediated spray pyrolysis method for synthesizing amorphous NiFe bimetal oxide hollow microspheres (A-NiFeOx) with controlled crystallinity, hierarchical porosity,
Hazardous situations involving radioactive, chemical, and other dangerous materials pose significant risks to emergency responders. In such situations, robots can support civil forces in reconnaissance and mitigation. However, this requires the development of robotic systems with novel AI-based assistance functions, operation procedures, and raises new ethical and legal questions. To address these
This paper presents a search for a new Z′ resonance decaying into a pair of dark quarks which hadronise into dark hadrons before promptly decaying back as Standard Model particles. This analysis is based on proton-proton collision data recorded at s = 13 TeV with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, corresponding to an integrated luminosity of 139 fb−1. After sele
Background: Ageing-in-place policies have increasingly shifted elder care responsibilities onto family members. Among older cohabiting couples, one’s partner’s illness significantly impacts the other’s daily life and well-being.Aim: To explore the responsibilities and strategies of caregiving partners in older cohabiting couples from the perspectives of cohabiting caregivers.Methods: A qualitative
It has been a century since the birth of philosopher Gilles Deleuze (1925-95). At his friend’s expense, Michel Foucault once joked, saying that un jour ce siecle sera peut-etre deleuzien: “perhaps one day this century will be known as Deleuzian?” Is there truth to the notion that the present moment expresses something of a “Deleuzian aeon” for the humanities, and what are its ramifications for bib
Biases in animal behaviour research are inevitable consequences of our societal and cultural standpoint. To remove our biases, the first stage is to identify them. We call on individual researchers to adopt a more active approach to addressing bias within their research. We propose that biases exist within a matrix defined by the general acceptance of a bias's existence and the understanding of th
Power required to fly for a bird generally follows a U-shaped function of airspeed, with higher cost at both low and high speeds. Because power required increases with body mass faster than power available from flight muscles, larger birds may experience restricted flight speed ranges and climbing capabilities. Previous studies found limited flight performance in cormorants. Adapted for both fligh
Complexity and innovation are emerging as fundamental issues for the future of human life and society. To deal with them, different versions of systems thinking have been proposed. However, System-of-Systems (SoS) thinking, based on the biperspectival principle and human reflexivity, has not yet been clearly recognized. The unclear distinction between ‘systems’ and ‘SoS’ thinking often results in
Solvers’ participation is essential for successful implementation of crowdsourcing contests for problem solving (CCPS). Many efforts have been made to investigate solvers’ various participation behaviours in CCPS. Whether or not a solver will conduct a behaviour is the result of decision making. However, to our knowledge, few studies concentrated on solvers’ participation from a decision process p
The Economic Dispatch Problem (EDP) plays a critical role in power system operations by trying to allocate power generation across multiple units at minimal cost while satisfying complex operational constraints. Traditional optimization techniques struggle with the non-convexities introduced by factors such as valve-point effects, prohibited operating zones, and spinning reserve requirements. Whil
There has been great interest in the rationales for transformative innovation policies (TIP), including those following a mission-oriented logic. However, few studies have investigated how public administration can effectively implement TIP. To study this, we first identify from existing literature four TIP governance tasks (creating legitimacy and leadership, coordination across levels/instrument
The current paper focuses on the conceptual design and numerical analysis of a four-stage centrifugal pump for the fuel system of a turbofan engine with liquid hydrogen as fuel. Liquid hydrogen is challenging at high pressures due to its special fluid properties. The design condition for the pump is set at take-off, to raise the pressure of liquid hydrogen from 6 bars at the outlet of a low-pressu
