To evaluate the diagnostic yield of the ECG criteria for ST-elevation myocardial infarction in a large cohort of emergency department chest pain patients, and to determine whether extended ECG criteria or reciprocal ST depression can improve accuracy. Design: Observational, register-based diagnostic study on the accuracy of ECG criteria for ST-elevation myocardial infarction. Between Jan 2010 and

Based on Marcus theory, the photoinduced electron transfer properties of D-A type non-fullerene acceptor organic solar cells (OSCs) under the dependence of external electric field (Fext) were investigated. The research results shown that the charge transfer mode under different Fext intensities changes with certain regularity. Focusing on the important parameters (ΔG, λ, and VDA) that affect the c

The size tunable color of colloidal semiconductor quantum dots (QDs) is probably the most elegant illustration of the quantum confinement effect. As explained by the simple “particle-in-a-box” model, the transition energies between the levels increase when the “box” becomes smaller. To investigate quantum confinement effects, typically a well-defined narrow size distribution of the nanoparticles i

Objective: Individuals with psychiatric illness suffer from poorer physical health compared with the general population and have a higher risk of developing cardiovascular and metabolic diseases. This cross-sectional study aims to describe the prevalence of lifestyle and cardiovascular risk factors and the association with self-reported psychiatric symptoms in a population of 40-year-old individua

With the explosive growth of communication traffic, increasing the modulation bandwidth of semiconductor lasers has attracted significant attention. However, after rapid progress is achieved, further increasing the modulation bandwidth of semiconductor lasers is hampered by the slow charge-carrier dynamics. Here, a room temperature, single-mode perovskite nanolaser with sub-picosecond pulses, enab

Genetic variation at the MTIF3 (Mitochondrial Translational Initiation Factor 3) locus has been robustly associated with obesity in humans, but the functional basis behind this association is not known. Here, we applied luciferase reporter assay to map potential functional variants in the haplotype block tagged by rs1885988 and used CRISPR-Cas9 to edit the potential functional variants to confirm

Introduction: Health problems in people with intellectual and developmental disability (IDD) are traditionally known to be common in adults of all age, with at least twice as many health problems in this group as the general ageing population. In addition, there is considerable international evidence indicating an earlier death for people with IDD compared to the general population, exacerbated by

Wellbefy is a company that offers its customers a digital platform with the goal to increase wellbeing at workplaces. Through their platform and their users, they are obtaining data connected to areas in which problems often occur, such as sleep or stress. The platform can be used by anyone working at a company, from the boss to an employee. The problem with the current platform is that it can on

Even though the eclectic paradigm was founded approximately 50 years ago, it remains among the leading frameworks for firms determining whether to engage in foreign direct investment (FDI). The framework asserts that multinational companies (MNCs) only will engage in FDI if they have ownership, location, and internalization advantages. There is currently a research gap pertaining to if there are a

This study explores the influence of sustainable entrepreneurship education (SEE) on the ability to recognize sustainable business opportunities. Using a series of semi-structured qualitative interviews, data was collected from participants in a SEE program at Lund University. The findings reveal that SEE enhances the ability of students to identify and evaluate sustainable business opportunities

This report presents an innovative approach to industrial automation, focusing on the development of an automated system for erecting and filling cardboard boxes with wax jars. The project, executed in collaboration with Odigo Consulting and Scandinavian Hair Company (SHC), aimed to showcase enhanced production efficiency for small and medium-sized enterprises through the implementation of co

This report aims to investigate the possibilities to implement a high temperature heat pump at a Dow facility in Landskrona. By implementing a heat pump, waste heat from the production can be recovered and reused in the process. The question at issue is whether there will be enough energy available when needed due to an intermittent process, and if a heat pump will be feasible to implement. To inv

Abstract Title: Beyond the Numbers - A Study on the Effect of Managerial Judgment on Operational Risk Hand-In Date: 24th May 2024 Seminar Date: 30th May, 2024 Course: BUSN79 - Degree Project in Accounting and Finance Authors: Christian Brams & Felix Walter Persson Advisor: Elin Funck Five Keywords: Managerial judgment, Operational risk, Heuristics, Decision-Making Process, Economic- and

Companies face the strategic challenge of expanding into adjacent markets or areas. This often requires a choice between building internally, acquiring through purchases, or forming partnerships to address the opportunity. While extensive literature exists on each of these options individually, there is limited research on the decision-making process that evaluates all these alternatives collectiv

Based on the DCV-C60 system of fullerene acceptor organic solar cell active materials, the charge transfer process of D-A type molecular materials under the action of an external electric field (Fext) was explored. Within the range of electric field application, the excited state characteristics exhibit certain regular changes. Based on reducing the excitation energy, the excitation mode shows a t

Lead-free metal halide perovskites are emerging as less-toxic alternatives to their lead-based counterparts. However, their applicability in optoelectronic devices is limited, and the charge transport dynamics remain poorly understood. Understanding photo-induced charge and structural dynamics is critical for unlocking the potential of these novel systems. In this work, ultrafast optical and Raman

The influence of alkyl chain on the physical and photochemical properties of D-A-π-A-π-A sensitizers (GZ-121 and GZ-124) for dye-sensitized solar cells (DSSCs) was investigated through density functional theory (DFT). Key aspects examined include geometry, optical characteristic, electron injection, intramolecular charge transfer, and dye regeneration. Adsorption models of dye@TiO2, short-circuit

We present a temperature-dependent intensity modulated two-photon excited fluorescence microscopy technique that enables high-resolution quantitative mapping of charge carrier dynamics in perovskite microcrystal film. By disentangling the emission into harmonics of the excitation modulation frequency, we analyze the first and second order charge carrier recombination processes, including potential
