Diabetic retinopathy is an ophthalmic complication of diabetes that currently affects 93 million people worldwide. Diabetic macular edema is a subtype of diabetic retinopathy that is characterized by leaking blood vessels in the central part of the retina, and it is a major cause of vision loss in individuals with diabetes. Screening for retinopathy is performed at regular intervals to identify su
The world is facing of a number of great challenges as the population is growing and living habits are getting more resource demanding. At the same time as food security has to be assured, growth in biofuel and meat production pose a risk for increasing land use conflicts and negative environmental consequences. In this report production of food, feed and biofuels are discussed from a land use pe

In this thesis, a fault detection and diagnosis system is developed for the Crazyflie 2.1 unmanned aerial vehicle. Different types of faults are investigated and suitable methods and tests are implemented. The system is mainly developed for the lighthouse positioning, but the tests and methods are generic and suitable for other parts of the Crazyflie eco-system. For the faults investigated, differ
This master thesis investigates the synthesis, structural characterization and electrochemical performance of copper(II) oxide (CuO) and cobalt-doped CuO nanofibers as electrocatalysts for the electrochemical nitrate reduction reaction (NO3-RR). The overarching aim is to assess their potential for sustainable ammonia production under ambient conditions. A series of exploratory synthesis trials rev
This thesis examines the market access barriers faced by small-scale producers in Bolivia, with a focus on Chiquitania, Los Valles Cruceños, and Zongo. Drawing on 15 semi-structured interviews with producers, vendors, university staff, and institutional actors, it analyses how structural, institutional, and relational barriers shape not only producers’ ability to reach markets, but also their abil
The Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change represents the state of knowledge of anthropogenic disruption to the climate system, its diverse ecosystem and societal impacts, and the imperative for and challenges of mitigation and adaptation responses. It is foundational for global climate policymaking. This paper examines the place of tourism in AR6 and review
It is evident that Sarajevo has major challenges to create a dynamic culture around entrepreneurship. The reports also outline major constraints entrepreneurs face when hiring and retaining qualified labour. By applying the ILO’s Inclusive Entrepreneurship Ecosystem Framework, this report presentsthe root causes behind these challenges, and proposes ways forward to better include women and young p
BACKGROUND: Amyloid-β (Aβ) is a normal product of neuronal activity, including that of the aggregation-prone Aβ42 variant that is thought to cause Alzheimer's disease (AD). Much knowledge about AD comes from studies of transgenic rodents expressing mutated human amyloid-β protein precursor (AβPP) to increase Aβ production or the Aβ42/40 ratio. Yet, little is known about the normal expression of Aβ
We report the synthesis of various binary and ternary inorganic and hybrid organic-inorganic iodide nanocrystals (NCs) starting from molecular iodine (I2). The synthesis described herein utilizes a reaction between I2 and oleylamine, which results in oleylammonium iodide, an iodide precursor that can be directly used in the preparation of iodide-based NCs. The generality of the synthesis was demon
In this work, we proposed to include remote sensing techniques as a part of the methodology for natural lake bottom mapping, with a focus on the littoral zone. Due to the inaccessibility of this zone caused by dense vegetation, measurements of the lake bottom and the coastline are also difficult to perform using traditional methods. The authors of this paper present, discuss and verify the applica
Investigating the optical properties of various chemical compounds using UV-vis spectrophotometers is an essential part of education in chemistry. However, commercial spectrophotometers are usually treated as "magic black boxes", where the dominant majority of optical elements are hidden "under the hood". This often limits understanding of the mechanisms behind the generation of spectral curves, w
Avhandlingen är en studie av hur stöd och service organiseras kring fyra barn med funktionshinder och deras familjer. I denna service är normalt flera olika formella organisationer involverade, som barnhabilitering, förskola/skola/särskola, hjälpmedelscentral, assistentorganisationer, sjukvård m fl. Dessutom kan barnets och familjens situation vara komplicerad på många sätt. Själva funktionshindreThis study explores the organising of services for disabled children and their families in Sweden. It is based on 83 interviews with parents and involved staff surrounding four disabled children, with both physical and intellectual disabilities, and between two and nine years old. Further, 15 meetings between parents and staff were observed, primarily serving as background material. The service pr
Despite a long history and the vast number of applications demonstrated, very few market products incorporate acoustophoresis. Because a human operator must run and control a device during an experiment, most devices are limited to proof of concepts. On top of a possible detuning due to temperature changes, the human operator introduces a bias which reduces the reproducibility, performance and rel
Background: The software engineering community has expressed growing concern regarding the need for more connections between research and practice. Despite the large amount of knowledge researchers generate, its impact on real-world practice is uncertain. Meanwhile, practitioners in industry often struggle to access and utilize relevant research outcomes that could inform and enhance their work.
This state-of-the-art handbook, the first in a series that provides medical physicists with a comprehensive overview into the field of nuclear medicine, is dedicated to instrumentation and imaging procedures in nuclear medicine. It provides a thorough treatment on the cutting-edge technologies being used within the field, in addition to touching upon the history of their use, their development, an
This state-of-the-art handbook, the third and final in a series that provides medical physicists with a comprehensive overview into the field of nuclear medicine, focuses on highlighting the production and application of radiopharmaceuticals. With this, the book also describes the chemical composition of these compounds, as well as some of the main clinical applications where radiopharmaceuticals
Background: Genome and transcriptome sequencing has greatly facilitated the understanding of biomass-degrading mechanisms in a number of fungal species. The information obtained enables the investigation and discovery of genes encoding proteins involved in plant cell wall degradation, which are crucial for saccharification of lignocellulosic biomass in second-generation biorefinery applications. T
Background & Aims Predniso(lo)ne, alone or in combination with azathioprine, is the standard-of-care (SOC) therapy for autoimmune hepatitis (AIH). However, the SOC therapy is poorly tolerated or does not control disease activity in up to 20% of patients. We assessed the efficacy of mycophenolate mofetil (MMF) and tacrolimus as second-line therapy for patients with AIH. Methods We performed a r
