Popular Abstract in Swedish I denna avhandling studeras ledningsförmågan hos nanometer-stora kvantprickar tillverkade i halvledarmaterial. Halvledare är material vars ledningsförmåga ligger någonstans mellan ledare (metaller) och isolatorer. I halvledare kan ledningsförmågan ändras med elektriska fält, vilket har möjliggjort utvecklandet av halvledartransistorn. Utvecklandet av halvledartransistorThis thesis focuses on electron transport in single and double quantum dots defined in low-dimensional, narrow-band-gap III-V semiconductor materials. Fabrication schemes are presented for defining single and double quantum dots in lateral InGaAs/InP heterostructures, either by a combination of etching and local gating or solely by local top gating. The quantum dots are here electrostatically conf

BACKGROUND: – The clinical use of risk scores to guide treatment decisions and improve clinical outcomes has rarely been prospectively evaluated. This study aimed to evaluate whether a biomarker-based ABC-AF risk score–guided multidimensional treatment strategy improves long-term outcomes in patients with AF. METHODS: – The multicenter, registry-based, randomized, controlled, open-label study enro

Bangladesh is one of the most densely populated areas in the world, and Rapid urbanization has been a notable trend, with the urban population increasing from 5% to 42% between 1972 and 2023. This internal migration has led to a surge in demand for housing in cities like Dhaka, Chittagong, Sylhet, and Khulna. It is found from the Bangladesh Bureau of Statistics (BBS) that each year, 200,000 units

This master’s thesis examines similarities and differences in operational work, training, and the use of technology related to Smart Firefighting in Sweden and Hong Kong. Smart Firefighting has been proposed as a response to challenges arising from modern urban development, where data from smart buildings, combined with AI and digital tools, could support fire and rescue services. However, such da

The purpose of this conference paper is to showcase how the user experience (UX) methodology of design thinking can facilitate organizational change processes in situations of multiple and often conflicting values and opinions in university libraries. The paper also elaborates on the application of design thinking under both normal circumstances and Covid-19 restrictions. The conference paper is b

European VAT and the Sharing Economy aims to understand whether the current European Value Added Tax (EU VAT) system is sufficiently equipped to deal with the ongoing transformation of the supply chain as well as the increasing digitalization of the economy ushered in by the rise of multisided digital platforms. New digital platforms such as those of the sharing economy, have dramatically expanded

Critical infrastructure such as transportation, power, telecommunication and water supply systems accommodate and enable flows of essential goods and services that modem societies are highly dependent upon. These critical flows connect countries, organizations and communities, and are imperative for upholding vital societal functions. Disruptions of such flows hold the potential of severe and pote

Proof load testing may be performed to confirm the reliability of the bridge for an existing classification or to prove the reliability for a higher classification.In this paper, a probabilistic decision analysisapproach is applied to the scenario for the evaluation of target proof load in the situation where information on the bridge resistance model is lacking. In this case, the resistance model

Organizational crisis can serve as a base to provide an opportunity to an organization for enhancing individuals, organizations, and communities. The healthcare sector is one of those sectors that remains under continuous pressure to provide high-quality service delivery to the patients. Hence, the requirement of innovation for this sector is huge when compared to other sectors. The majority of th

Multi-story apartment buildings, also known as multi-family or multi-unit residential buildings, represent the largest share of newly constructed, residential floor area in Norway, Sweden and Finland. Since the start of 2021, these buildings are required to be nearly-zero-energy under the Energy Performance of Buildings Directive. However, there has been limited research into defining solution-set

On February 23, 2022, The EU Commission published its Proposal for a Directive of the European Parliament and of the Council on Corporate Sustainability Due Diligence and amending Directive (EU) 2019/1937 (“CSDDD” or “the Proposal”). The purpose of the Proposal, to further the “Union’s transition to a climate-neutral and green economy in line with the European Green Deal and in delivering on the U

Water scarcity is one of the major challenges in semi-arid and arid areas. Drivers for water scarcity include climate change, population growth, economic, and agricultural development. This paper presents a framework for assessing water scarcity under the impact of climate, industry, and socio-economic changes in the Qazvin Plain, Iran. A system dynamics model is developed and calibrated using his

Purpose: The purpose of this study was to describe experiences of working as a paid part-time firefighter (PTF) in Swedish rural areas. Design/methodology/approach: An inductive explorative design was used, based on interviews with 18 paid PTFs in Sweden. Data were analyzed using qualitative latent content analysis. Findings: Three themes emerged from the interviews and describe paid PTFs’ experie

Hydrodynamic forces from ships operating in sheltered, confined fairways can result in increased wave impact and sediment transport leading to loss of land and habitats. Nature-based solutions (NBS) offer the potential to mitigate ship-induced erosion and increase biodiversity and ecosystem services. The aim of this study is to evaluate the performance of NBS in a sheltered, confined fairway locat

Background: Parents of young children are a vulnerable group with an increased risk of stress-related health problems compared to adults without children. Low occupational balance has been identified as a risk factor for stress-related disorders. Aim: The study aimed to describe occupational balance in parents of pre-school children and to explore potential differences between mothers and fathers.

The building industry has a major environmental impact in terms of global energy use, carbon emissions, resource use, and the production of waste. To reach ambitious international environmental goals, the building industry faces a need for large-scale change. Circular strategies for buildings include using building and materials longer through lifetime extension strategies, reuse, sharing, renovat

Previous research has identified sociodemographic inequalities in fire prevention measures. This study examined whether sociodemographic differences persist in the Swedish population concerning fire prevention measures and particularly whether there remains an inverted u-curve related to age in protection habits. Additionally, it investigated whether fire protection practices are influenced by the

Non-traditional stable isotope systems are increasingly used to study micronutrient cycling and acquisition in terrestrial ecosystems. We previously proposed for zinc (Zn) a conceptual model linking observed isotope signatures and fractionations to biogeochemical processes occurring in the rice soil environment and we suggested that 2’deoxymugineic acid (DMA) could play an important role for rice

Background: Depression and anxiety often reduce people’s ability to cope with everyday occupations. There is a lack of knowledge about such problems in people of working age with depression and anxiety. Aim: To describe which problems people with depression or anxiety disorders experience when performing everyday occupations and which occupations are affected. Materials and methods: Data based on
