Under the Paris Agreement, nations have committed to preventing dangerous global warming. Scenarios for achieving net-zero emissions in the second half of this century depend on land (forests and bioenergy) to remove carbon from the atmosphere. Modelled levels of land-based mitigation could reduce the availability of productive agricultural land, and encroach on natural land, with potentially sign

This thesis explores how older people construct meaning, use and make sense of three kinds of robots in their homes. The exploration is undertaken in empirical studies of an assistive robot, an eHealth system, and robotic vacuum cleaners. The research draws on data collected through interviews and observations of older people in relation to three robots. The results show that older people’s domest

The antibody response to SARS-CoV-2 shows biased immunoglobulin heavy chain variable (IGHV) gene usage, allowing definition of genetic signatures for some classes of neutralizing antibodies. We investigated IGHV gene usage frequencies by sorting spike-specific single memory B cells from individuals infected with SARS-CoV-2 early in the pandemic. From two study participants and 703 spike-specific B

Purpose: Investigating the use of the EORTC bladder cancer (BC) modules by evaluating: (a) study contexts/designs; (b) languages/countries in which the modules were administered; (c) their acceptance by patients/investigators; and (d) their psychometric properties. Methods: A systematic review was performed with studies from 1998 until 20/10/2021 in five databases. Articles/conference abstracts us

Various techniques are available for the conversion of lignocellulosics to fuel ethanol. During the last decade processes based on enzymatic hydrolysis of cellulose have been investigated more extensively, showing good yield on both hardwood and softwood. The cellulase production of a filamentous fungi, Trichoderma reesei Rut C 30, was examined on carbon sources obtained after steam pretreatment o

In this thesis I study the performances of artificial neural networks (ANNs) and three various ARCH-type models to predict weekly volatility of the Swedish (OMXS30), the British (FTSE100) and the Australian (S&P/ASX200) major stock indices. The three various ARCH-type models are the GARCH(1,1), the EGARCH(1,1) and the TGARCH(1,1). The purpose is to investigate if ANNs outperform the more tradi

Background: The COVID-19 pandemic has necessitated changes in European healthcare systems, with a significant proportion of COVID-19 cases being managed on an outpatient basis in primary healthcare (PHC). To alleviate the burden on healthcare facilities, many European countries developed contact-tracing apps and symptom checkers to identify potential cases. As the pandemic evolved, the European Un

Background: Somali women suffer from one of the highest maternal mortality rates in the world. Somalia characterises a specific low-income country situation with a mix of newly urbanized and nomadic culture combined with a frail health care infrastructure set in a post-conflict era. Very little is known about the effects that these contextual factors can have on maternal mortality. Objectives: To

BACKGROUND: Traditionally oocytes have been exposed to sperm overnight, for 16-20 h. This long period of co-incubation, however, has been shown to create problems with high levels of reactive oxygen species (ROS), which may affect embryo viability and cause hardening of the zona pellucida. Recently, a positive effect of reducing the co-incubation time to 90-120 min was reported. The objective of t

Microstrip patch antennas have become essential in modern communication systems due to their compact size and ease of fabrication. However, their performance is often constrained by narrow bandwidth, low radiation efficiency, and low gain, especially in miniaturized designs. The performance limits of microstrip patch antennas are helpful in understanding and overcoming these challenges. These perf

Trellis decoding is a popular method to recover encoded information corrupted during transmission over a noisy channel. Prominent members of this class of decoding algorithms are the Viterbi algorithm, which provides maximum likelihood estimates, and the BCJR algorithm, which is a maximum a posteriori estimator commonly used in iterative decoding. In this thesis, the Viterbi algorithm is chosen si

Background:The case company Atlas Copco has a decentralized organisation where the product responsibility has been delegated to the Product Line Manager located at the production facility. To manage the product portfolio and make strategic and tactical business decisions related to the products, information about product performance and profitability is a key input. Today, the Product Line Manager

The progress made in the field of patents on pharmaceuticals the last fifteen years, has been of continuous change and adaptation. From the introduction of the TRIPS Agreement in 1995, where patents on pharmaceuticals became a necessity for all Member States of the WTO, to today, where a ratification of the TRIPS Amendment is ongoing, and might be a mean to enhance access to medicine for all peopl

The upcoming ESA space astrometry mission Gaia, planned to be launched in early 2012, has been designed to scan the whole sky (flux limited, corresponding to magnitude 20 in the Gaia passband) during a five-year observational phase. It will measure the astrometric parameters (positions, parallaxes and proper motions) of more than one billion stars, complemented by multi-epoch spectrometric and rad
