We have studied whether dissociation of the S2B sulfide ligand from one of its two coordinating Fe ions may affect the later parts of the reaction mechanism of nitrogenase. Such dissociation has been shown to be favourable for the E2–E4 states in the reaction mechanism, but previous studies have assumed that S2B either remains bridging or has fully dissociated from the active-site FeMo cluster. We

Bakgrund: Kvinnor som upplevt våld i nära relation (VINR) har en högre tendens att genomgå operativa ingrepp. Vikten av att identifiera tecken och symtom är avgörande för att vårdpersonal ska upptäcka våldsutsatta kvinnor. En god utbildning inom VINR ger förutsättningar för vårdpersonal att fråga om våldsutsatthet och hjälpa utsatta patienter. Syfte: Syftet var att beskriva operationssjukskötersk

A team of clinical researchers at Lund University found that electromagnetic radiation, such as that used in GSM-900 mobile telephones, at low non-thermal power values (

Amyloid beta (Aβ) proteins are a group of proteins able to form fibrillar aggregates that are linked to the adverse neurological effects seen in Alzheimer’s disease [11]. The molecular mechanisms that lead to the Aβ aggregation are complex processes, and efforts to understand them are being made by investigating the kinetics and thermodynamic properties of the protein. The solubility of the protei

Detta examensarbete undersöker den tekno-ekonomiska genomförbarheten av att integrera vätgaslagringssystem med havsbaserade vindkraftsparker på den svenska energimarknaden. När Sverige övergår till ett mer förnybart energisystem skapar variationen i vindkraftsproduktion utmaningar för nätstabilitet och elmarknaden. Vätgaslagring erbjuder en potentiell lösning genom att omvandla överskottsenergi frThis thesis investigates the techno-economic feasibility of integrating hydrogen storage systems with offshore wind farms in the Swedish energy market. As Sweden transitions towards a more renewable energy system, the variability of wind power generation presents challenges for grid stability and the electricity market. Hydrogen storage offers a potential solution by converting excess wind energy

The purpose of this essay is to find out how the Swedish district court relates to children’s rights when sentencing young offenders to the new penalty called youth surveillance. Since the Convention on the Rights of the Child is a part of the Swedish law, there was an interest to examine whether law in books actually is implemented in law in action regarding the penalty of youth surveillance. T

This chapter examines the development of maternal and infant mortality and its connection to changes in medical and healthcare treatment of mothers and infants in the city of Landskrona, Sweden, and its rural hinterland between 1905 and 2015. The authors show that maternal mortality, stillbirth rates, and infant mortality declined strongly in this period. In parallel, hospitals began to admit more

Transition to vehicles with reduced-emission fuels such as Compressed Natural Gas (CNG), LNG (Liquified Natural Gas), Biogas, and Hydrogen gas is an important sustainable approach in the mobility industry. The pressure vessels that are installed as fuel containers on such vehicles are critical components in this transition. However, the Type IV Carbon-Fibre-Reinforced Plastics (CFRP) pressure vess

Background and aims: Active aging is the process through which people strive to maintain wellbeing when growing old. Addressing the lack of research on active aging in the context of housing, the aim was to describe active aging among people aged 55 and older considering relocation and investigate whether perceived housing moderates the relationship between functional limitations and active aging.

Increasing issues related to agriculture are being identified. To counter these issues, some type of methods of agriculture are being introduced and reintroduced, such as agroecology. With its focus on practices, sciences and social movement, agroecology is considered as a promising solution to bring a paradigm change to agriculture as we know today and to provide better quality food, produced in

Deforestation, mainly driven by agricultural expansion, is a global problem, interlinked with many pressing sustainability issues of our time, first and foremost, climate change. Previous private corporate initiatives and public policies such as FLEGT and the EUTR have not succeeded in overturning the trend. As a response to that, EU deforestation regulation was developed as the new demand-side po

The Transiting Exoplanet Survey Satellite (TESS) uses transit photometry to detect exoplanets. To confirm if it is a planet, a second detection method is used to determine the planet's mass. But with the number of candidates waiting for confirmation, statistical tools have been developed to validate exoplanets so that false positives could be ruled out quickly. One such tool is the Tool for Ra

Recent years’ publications have shown how valuable information can be in the integrity management of civil structures. Monitoring systems increase the knowledge about the structural state, improving the prioritization of the interventions, and the selection of optimal maintenance strategy and thereby allowing for budget optimization and risk minimization. This paper investigates the effect of mult

Floods and wildfires are two critical hazards that impose substantial direct and indirect costs to society, including the resource needs of rescue services. Their occurrence is strongly linked to meteorological conditions, playing a fundamental role in hazard development and assessment. These hazards are notably distinguishable due to opposing weather requirements, wet conditions for floods and dr
