The relationship between business cycles and mortality has been a highly debated subject in the field of economics. The majority of previous studies, using the unemployment rate as the main proxy for macroeconomic conditions, have found ambiguous effects largely depending on how the effect is estimated. This thesis follows the methodology used by Ruhm (2000), but instead applies aggregate data for
The DARPA Grand Challenge (DGC) 2005 was a competition, in form of a desert race for autonomous ground vehicles, arranged by the U.S. Defense Advanced Research Project Agency (DARPA). The purpose was to encourage research and development of related technology. The objective of the race was to track a distance of 131.6 miles in less than 10 hours without any human interaction. Only public GPS signa
Syftet med vår uppsats var att utreda behovet av multilingvistisk kundservice på den svenska marknaden samt att studera hur företag hanterar kunder med icke-svensk bakgrund. Vårt sekundära syfte vara att undersöka affärsmöjligheter för ett multilingvistiskt call center. Uppsatsens teoretiska ramverk består av kundbaserad teori, där teorier kring Customer Relation Management, kundservice, call cent
With this thesis we want to prove that by using a single formula for picking stocks, Joel Greenblatt’s ‘’Magic Formula’’, it is possible to achieve returns higher than those achieved by a related index. To prove this, we will construct a portfolio, according to “The Magic Formula”, and backtest the portfolio in the Swedish stock market. The test period will be March 1999 to January 2010 and we wil
As part of a research grant aimed at producing chicken feed from the novel microalgae Scenedesmus sp., called the ReMAPP project, this thesis investigates opportunities to increase the conservation potential and protein digestibility utilizing solid-state lactic acid fermentation and commercial enzyme additives. The lactic acid fermentation mimics the traditional agricultural ensiling process, whe
Purpose: Environmental sustainability in the wine industry has become increasingly important. Most countries have implemented programs to ensure sustainability. In South Africa, the majority of wine farms belong to the sustainability scheme. However, small and medium wine farms face challenges in adopting sustainability practices. Therefore, this research investigates the barriers faced by SME win
This thesis examines the way in which Sweden opted to set up its taxation on the supply of energy from renewable sources and whether they are in line with EU tax law. Windmills in Sweden are granted a lower-rate tax than other sources of renewable energy production, which is stated to be within the scope of the de minimis Regulation. Firstly, the thesis starts by examining what State aid is, looki
This thesis investigates the remanufacturing potential of the electric front cross differential (eFXD) within the context of the circular economy (CE) and the R‑framework. Environmental assessment, mechanical validation and structured component classification are combined to identify opportunities and limitations for remanufacturing. The results show that a limited number of components, the tube h
The essay deals with implications for Human Rights development in light of China's rise to power. It discusses the problem from three perspectives, China's Human Rights commitment, the clash between western and Asian values and China's potential influence. It is mainly an overview and discussion of the problems and complexities involved in the development. From these three perspective
In this thesis, we evaluate the side-channel security of the NIST HQC post-quantum cryptosystem by analysing the official FPGA decapsulation implementation. A hardware wrapper was created to interact with the HQC decapsulation modules, enabling ciphertext decapsulation with precise power trace capturing using a ChipWhisperer CW305 and Husky setup. A dataset with 20k power traces was generated from
As plastic pollution in aquatic environments persists, gaining a deeper understanding of nanoparticles has become increasingly important. Yet, the question remains: what happens to plastic as it breaks down into smaller components, and ultimately, what end products are formed? Current plastic degradation methods are limited in their environmental applicability and efficiency. This study aims to pr
Across Europe, breeding bird species are decreasing in several types of habitats. Deciduous forest specialist birds are facing a loss of habitat due to the forest management that removes important key components in the forest, e.g. dead wood. Already in Sweden three woodpecker species that are deciduous forest specialist have decreased in population: one has become locally extinct (middle spotted
The operation of instruments and detectors in laboratory or beamline environments presents a complex challenge, requiring stable operation of multiple concurrent devices, often controlled by separate hardware and software solutions. These environments frequently undergo modifications, such as the inclusion of different auxiliary devices depending on the experiment or facility, adding further compl
Nickel-based catalysts are the most promising alternative to replace platinum in hydrogen conversion devices in alkaline media. One approach to narrowing the performance gap between Pt and Ni is to fine-tune the nickel surface coverage by (hydr) oxide (NiOxHy) species, which determines its electrocatalytic activity for the hydrogen oxidation (HOR) and hydrogen evolution (HER) reactions. As Ni easi
Effective medical education relies on clearly defined learning objectives that foster deep and meaningful learning. This article presents a consensus-driven proposal for national learning objectives in dermatology and venereology within Sweden’s new medical programme qualifying for licensure. The primary aim is to harmonize educational standards across all medical faculties and to establish a comm
INTRODUCTION: Automated cerebrospinal fluid (CSF) biomarker assays have largely replaced manual immunoassays for measuring amyloid pathology in CSF. We refitted and validated the ABIDE model, predicting progression from mild cognitive impairment (MCI) to dementia, with CSF measurements from the automated Elecsys platform. METHODS: We included 2413 MCI participants (998 [41%] amyloid-positive) from
BACKGROUND: Since the first national guideline for managing obesity in adults and children in Canada was published in 2007, new evidence has emerged and guideline standards have evolved. Our purpose is to describe the protocol used to update the Canadian clinical practice guideline for managing pediatric obesity. METHODS: This guideline will update the pediatric components of the 2007 Canadian cli
Importance: While clinical disease stages remained largely unchanged in the 2024 update of the Alzheimer disease (AD) criteria, tau-positron emission tomography (PET) was introduced as a core biomarker and its spatial extent was incorporated into the revised biological stages of the disease. It is important to consider both the clinical and the biological stages and understand their discrepancies.
A search is presented for a heavy scalar (H) or pseudo-scalar (A) predicted by the two-Higgs-doublet models, where the H/A is produced in association with a top-quark pair (tt¯H/A), and with the H/A decaying into a tt¯ pair. The full LHC Run 2 proton–proton collision data collected by the ATLAS experiment is used, corresponding to an integrated luminosity of 139fb-1. Events are selected requiring
