Radio signals are used broadly as navigation aids, and current and future terrestrial wireless communication systems have properties that make their dual-use for this purpose attractive. Sub-6 GHz carrier frequencies enable widespread coverage for data communication and navigation, but typically offer smaller bandwidths and limited resolution for precise estimation of geometries, particularly in e
Background The COVID-19 pandemic has presented many countries with significant health system and economic challenges. The role of civil-military cooperation in a health crisis of the magnitude presented by COVID-19 remains virtually unexplored. This review aims to detect and identify typologies, if any, of associations between security or military systems and the national response measures during
Increasing cross-Atlantic tensions have raised concerns that the United States may leverage European digital dependencies for political gain. This has made the EU’s dependence on US cloud providers increasingly politically salient, as cloud infrastructure forms a central part of the European digital economy and may create vulnerabilities to geopolitical coercion. This thesis examines how the EU ba
Purpose:Rapid changes in diet, physical activity and food systems have contributed to rising obesity in developing countries. As national incomes increase, obesity often shifts from higher to lower socioeconomic groups, a process known as the obesity transition. Small Island Developing States (SIDSs) face particular risks because of limited health system capacity, geographic isolation and dependen
With approximately 94 percent of traffic accidents being caused by human error, improving driver behaviour has the potential to save lives. To encourage safer driving, Volvo Cars is developing a Safety Coach feature for their mobile application. However, pilot studies of a minimum viable product (MVP) indicated low user retention, suggesting the need for design elements that better support user en
This Master’s Thesis explored how traditional computer vision methods and deep learning methods could be used to estimate hardwood and softwood fibre distributions in paperboard. 11 mixtures ranging from 100% hardwood to 100% softwood with 10% increments were analysed. The study compared the usefulness of tomograms and radiographs for the given task. It was found that traditional methods did not
This thesis examines how PR staff at a diplomatic mission adapt institutional communication to social media in their everyday work, and which organisational, professional, and platform-related conditions facilitate or constrain this work. As diplomatic communication increasingly takes place through social media content, embassies must translate central directives into locally relevant and platform
This project examines whether a Taylor-based risk-factor mapping framework can accurately and efficiently estimate Value at Risk for option-heavy portfolios without the high computational cost of full revaluation. The method maps changes in portfolio value to a selected set of market risk factors, including equity spot returns, foreign exchange rates, interest-rate curves, and principal components
Marine microorganisms have the potential to disperse widely with few obvious barriers to gene flow. However, among microalgae, several studies have demonstrated that species can be highly genetically structured with limited gene flow among populations, despite hydrographic connectivity. Ecological differentiation and local adaptation have been suggested as drivers of such population structure. Her
Online hemodiafiltration (HDF) is a dialysis modality that can improve patient outcomes beyond those achieved with conventional high-flux hemodialysis (HD) in patients with kidney failure. The CONVINCE trial, the latest and the largest of a series of randomized trials comparing HDF with HD, demonstrated a 23% reduction in the risk of all-cause mortality with high-volume HDF compared to high-flux H
Introduction: Reversed phase liquid chromatography (RPLC) is a central analytical technique in pharmaceutical and biopharmaceutical science, where it is essential to reliably detect, separate, quantify, and purify drugs, of which a majority contain basic groups. Background: Basic analytes often exhibit poor peak shape, for example tailing, due to mixed-mode interactions with the stationary phase.
Ensuring close control of critical quality attributes (CQAs), such as post-translational modifications (PTMs), in therapeutic monoclonal antibodies (mAbs) is essential for maintaining function and batch homogeneity in large-scale production. Common PTMs include deamidation, fragmentation, oxidation, charge variants, and glycosylations. This study aimed to evaluate CQA variations and correlate the
To properly understand regions of space behind interstellar dust, like the Galactic bulge, infrared (IR) observations are needed, as it passes through the dust with minimal absorption. In the past few decades, the development of IR telescopes has allowed for a much deeper understanding of our Galaxy’s stellar populations and history. To properly use the data which these IR telescopes produce howev
This thesis is a compilation thesis with the title Young persons at homes for care or residence. On legal security, legitimacy and trust with respect to decisions on young persons in care. The thesis is the result of two research projects within the scope of my research studies at the Faculty of Law, University of Lund, Sweden. The two separate studies share the common theme of the influence of le
Popular Abstract in Swedish Cancer i tjock- och ändtarmen är idag den tredje vanligaste formen av till döden ledande cancer i världen. Den är vanligast i de högindustrialise-rade delarna av världen: Europa, Nord-Amerika och Australien. Prognosen för den enskilde patienten är helt beroende på cancerns utbredning vid diagnostillfället. Cancerns utbredning bedöms idag enligt olika indelningsprincipeAim of the study Today´s methods for the staging of rectal carcinoma: ultrasonography with transrectal probe, CT, MRI or MRI with a rectal coil, all have limitations. The aim was therefore to develop a new, double-contrast MRI method for evaluation of rectal carcinoma. The idea was that a rectally applied contrast medium causing distension and signal void of the rectal lumen and an intravenous inj
Female reproductive success in the unisexual perennial clonal moss Hylocomium splendens was examined by recording, if the segment was reproductive [produced sporophyte(s)] or not, together with several distance-to-male and male density variables, and segment size. This was done for every female segment in a population over a 5 year study period. A high fraction of the population could be sexed bec
This paper examines the professional and scientific views on the social, ethical and legal issues that impact on the provision of genetic services in Europe. Many aspects have been considered, such as the definition and the aims of genetic services, their organization, the quality assessment, public education, as well as the partnership with patients support groups and the multicultural aspects. T
An integrated product recovery system was developed to separate urokinase from the cell culture broth of human kidney cells HT1080. Supermacroporous monolithic cryogels provided ideal matrices with respect to surface and flow properties for use as cell culture scaffold as well as for affinity chromatographic capture step of the enzyme in the integrated system. The urokinase was produced continuous
Preference studies of many different collembolan species have categorised collembolans being selective in their food choice. To clarify whether collembolan food selectivity is related to fitness parameters, three species, Folsomia fimetaria, Protaphorura armata and Heteromurus nitidus, were fed three fungal species, Alternaria infectoria, Mucor hiemalis and Penicillium hordei, representing fungi o
We reviewed the literature on urothelial carcinoma in the prostatic urethra and prostate. We concluded that the incidence of urothelial carcinoma in the prostatic urethra and prostate is probably underestimated. This fact warrants thorough follow-up of patients with high-risk bladder cancers and also whole-mount examination of the prostate after cystectomy to recognize the true incidence and exten
