Structural and chemical properties of anion exchanged CsPb(Br(1−x)Cl x )3 heterostructured perovskite nanowires imaged by nanofocused x-rays

Over the last years metal halide perovskites have demonstrated remarkable potential for integration in light emitting devices. Heterostructures allow for tunable bandgap depending on the local anion composition, crucial for optoelectronic devices, but local structural effects of anion exchange in single crystals is not fully understood. Here, we investigate how the anion exchange of CsPbBr3 nanowi

Order in Ruins : British Society and the Media Assemblage of The World at War c. 1970-1975

This thesis studies a period of intense crisis and creativity in British media, society, and culture, when the settled outcome of the Second World War (WW2) was perceived to be disintegrating. The post-world-war order was becoming an ‘order in ruins’. The thesis centres on a far-reaching analysis of the making of The World at War (WAW) in the early 1970s. A hugely popular televised documentary ser

Searches for New Physics Using Innovative Data Acquisition, Analysis, and Compression Techniques

När forskare blickar ut i universum ser de överallt spåren av en stor mängd osynlig massa. Massan finns där men det går inte att se den. Ungefär 80% av all massa i universum beräknas bestå av denna "mörka materia". Det är som att mänskligheten står på stranden och blickar ut över havet utan att veta vad vatten är. I partikelfysik studeras universums minsta beståndsdelar, elementarpartiklarna, för The high event rate delivered by the Large Hadron Collider (LHC) provides experiments with opportunities for new discoveries as well as challenges related to the large amounts of data recorded. Overcoming this requires innovative techniques in the three topics of this thesis: Data acquisition, data analysis, and data compression.In the data taking period of 2015-2018, the ATLAS experiment received

Label-free separation of peripheral blood mononuclear cells from whole blood by gradient acoustic focusing

Efficient techniques for separating target cells from undiluted blood are necessary for various diagnostic and research applications. This paper presents acoustic focusing in dense media containing iodixanol to purify peripheral blood mononuclear cells (PBMCs) from whole blood in a label-free and flow-through format. If the blood is laminated or mixed with iodixanol solutions while passing through

Current Trends and Future Developments on (Bio-) Membranes

Current Trends and Future Developments on (Bio-) Membranes: Engineering with Membranes discusses various aspects of membrane engineering. This includes, but is not limited to, the role of membranes in food production, treatment and recovery, their applications in electrochemical processes and devices, in drug delivery and in ionic materials, such as salts, acids and bases, recovery. In addition, t

Maximal ideals of reduced group C*-algebras and Thompson's groups

Given a conditional expectation P from a C*-algebra B onto a C*-subalgebra A, we observe that induction of ideals via P, together with a map which we call co-induction, forms a Galois connection between the lattices of ideals of A and B. Using properties of this Galois connection, we show that, given a discrete group G and a stabilizer subgroup Gx for the action of G on its Furstenberg boundary, i

Baseline breast tissue characteristics determine the effect of tamoxifen on mammographic density change

Tamoxifen prevents recurrence of breast cancer and is also approved for preventive, risk-reducing, therapy. Tamoxifen alters the breast tissue composition and decreases the mammographic density. We aimed to test if baseline breast tissue composition influences tamoxifen-associated density change. This biopsy-based study included 83 participants randomised to 6 months daily intake of placebo, 20, 1

Protein-Surfactant Interactions in Complex Systems : Study of Physical Stability of Proteins and Peptides

My objective has been to characterize protein-surfactant interactions in pharmaceutically relevant formulations. Thus, the behavior of selected excipients, proteins and peptides has been studied as the system in question is driven to the verge of instability in different manners; by inducing aggregation, by inducing surfactant complexation, or by inducing precipitation by increasing ionic strength

Solar Energy: Advancements and Challenges

Energy is a key source of economic growth due to its involvement as the primary input. Energy drives economic productivity and industrial growth. It can be considered as the prime requirement for the modern economy. Solar energy is a renewable source of energy that can be used to produce heat or generate electricity. The total amount of solar energy available on Earth’s surface is vastly in exce

Diagnosis of external ventricular drainage related infections with real-time 16S PCR and third-generation 16S sequencing

Objective: Investigate the performance of real-time 16S PCR and third-generation 16S sequencing in the diagnosis of external ventricular drain related infections (EVDRI). Methods: Subjects with suspected EVDRI were prospectively included at Uppsala University Hospital. Subjects were included into three groups: subjects with negative CSF culture with and without antibiotic treatment and subjects wi

Quantifying H&E staining results, grading and predicting IDH mutation status of gliomas using hybrid multi-dimensional MRI

Objective: To assess the performance of hybrid multi-dimensional magnetic resonance imaging (HM-MRI) in quantifying hematoxylin and eosin (H&E) staining results, grading and predicting isocitrate dehydrogenase (IDH) mutation status of gliomas. Materials and methods: Included were 71 glioma patients (mean age, 50.17 ± 13.38 years; 35 men). HM-MRI images were collected at five different echo tim

Gaming the System : How communities strategize around currencies, convertibility and cash transfers in Kenya

We draw from ongoing empirical research on the evolution of community currencies in Kenya, to analyse ways through which beneficiaries of cash transfers mediated by a community cryptocurrency – Sarafu – appropriate power and assert agency to obtain optimum financial benefits of the development intervention. We found that beneficiaries of the intervention have developed a deep knowledge of converti

Development of celiac-safe foods : prevention of transglutaminase 2 (TG2) deamidation of gluten in healthy non-celiac volunteers

In celiac disease, intestinal transglutaminase (TG2) produces immunogenic peptides by deamidation of gluten proteins. These products drive the celiac immune response. We have previously identified an interaction between gliadin and a food additive, E304i, which prevents gliadin processing (both deamidation and transamidation) by TG2, in vitro. In this study, we investigated if E304i could prevent

Effects of Self-Legitimation and Delegitimation on Public Attitudes toward International Organizations : A Worldwide Survey Experiment

Public views on international organizations (IOs) have become a matter of central concern. While actors in world politics increasingly try to legitimize or delegitimize IOs, scholars have begun investigating such phenomena systematically. This paper provides the most comprehensive IO (de)legitimation study to date. Building on cueing theory, and considering input as well as output legitimacy, I ex

ERS International Congress 2023 : highlights from the Airway Diseases Assembly

In this review, early career and senior members of Assembly 5 (Airway Diseases, Asthma, COPD and Chronic Cough) present key recent findings pertinent to airway diseases that were presented during the European Respiratory Society International Congress 2023 in Milan, Italy, with a particular focus on asthma, COPD, chronic cough and bronchiectasis. During the congress, an increased number of symposi
