From the first use of airborne electromagnetic (AEM) systems for remote sensing in the 1950s, AEM data acquisition, processing and inversion technology have rapidly developed. Once used extensively for mineral exploration in its early days, the technology is increasingly being applied in other industries alongside ground-based investigation techniques. This paper reviews the application of onshore AEM in Norway over the past decades. Norway’s rugged terrain and complex post-glacial sedimentary geology have contributed to the later adoption of AEM for widespread mapping compared to neighbouring Nordic countries. We illustrate AEM’s utility by using two detailed case studies, including time-domain and frequency domain AEM. In both cases, we combine AEM with other geophysical, geological and geotechnical drillings to enhance interpretation, including machine learning methods. The end results included bedrock surfaces predicted with an accuracy of 25% of depth, identification of hazardous quick clay deposits, and sedimentary basin mapping. These case studies illustrate that although today’s AEM systems do not have the resolution required for late-phase, detailed engineering design, AEM is a valuable tool for early-phase site investigations. Intrusive, ground-based methods are slower and more expensive, but when they are used to complement the weaknesses of AEM data, site investigations can become more efficient. With new developments of drone-borne (UAV) systems and increasing investment in AEM surveys, we see the potential for continued global adoption of this technology.

Active galactic nuclei host a supermassive black hole, a swarm of stars and black holes in a nuclear star cluster, and most critically, an accretion disk. Some of those stars and black holes will lie on orbits aligned with the disk, while others will have orbits that cross through it. Gas drag from the disk produces torques on their orbits that will align more orbits with the disk and once their orbits are sufficiently circular will cause embedded objects to migrate. Since more massive objects migrate faster, they can sweep up lighter black holes to form binaries on their way towards migration traps, where inwards and outwards migration meet, which can drastically increase binary formation rates. Experiencing more gas effects and dynamical encounters with other objects can cause these binaries to merge quickly relative to systems without such mechanisms. Once close enough, runaway orbital shrinkage will occur until they emit a burst of energy in the form of gravitational waves as they warp space-time in the final moments before coalescing into a single object that can be detected by ground-based gravitational wave observatories. The environment imprints unique signatures on the underlying black hole population that can be used to probe the conditions of the disk and star cluster with enough events. Black holes in this binary formation channel can participate in many merger events that may result in intermediate mass black holes due to their high concentration. Since the disk aligns the orbits and spins of embedded black holes over time and increases their mass through hierarchical events, the channel naturally replicates an anti-correlation present in the observed gravitational wave events where mergers between unequal mass black holes tend to have their spins more aligned with the binary’s orbital angular momentum. In addition to the gravitational waves, the shocks from the remnant interacting with the gas disk may produce a bright electromagnetic counterpart. The stars of the nuclear star cluster experience the same orbital changes caused by the disk, and massive stars may detonate in supernova explosions. While these light curves are well-studied and documented, the dense disk causes these to differ from naked supernovae as suggested by studies of those that must expand into dense envelopes expelled by strong winds of their progenitor stars. As such, these transients could become sources of contamination in searches for merger counterparts without understanding their characteristics. Additionally, while the accretion disk is an important factor for these phenomena, the details of their structures and conditions are not well constrained. Therefore, we can use these multi-messenger transient events to learn about the disk that produces them. In this dissertation I will show work I have done to explore this dynamic environment. I used Monte Carlo simulations to study populations of black hole mergers to understand how variations to initial conditions and physical processes affect their mass ratios and effective spins. I will also show hydrodynamic simulations of embedded supernovae and their light curves produced in post-processing radiative transfer calculations.

Annotation Hugh Trevor-Roper's experiences working for the Secret Intelligence Service (MI6) during the war had a profound impact on him and he later observed the world of intelligence with particular sharpness. To him, the subject of wartime espionage was as worthy of profound investigation and reflection as events from the more distant past. Expressing his observations through some of his most ironic and entertaining prose, Trevor-Roper wrote with a freedom he could not express publicly due to the Official Secrets Act. Based on previously unpublished material - including an extraordinary and previously-unseen correspondence with the exiled spy Kim Philby - this is a first-hand account of the intelligence world in World War II and its aftermath.

In 2007 the University of Northern British Columbia initiated a two-year elementary teacher education program at the Northwest Campus in Terrace, British Columbia. The program was designed to meet specific community needs in the North that arise from inequities in the cultural safety of Indigenous teachers and students. The authors share three collegial inquiries into the program’s contribution toward improving cultural safety in K-12 schools and meeting social justice challenges in the region’s communities. Culturally safe allocation of space became better understood, affective learning outcomes were recognized as important determinants of cultural safety, and teacher action in classrooms towards cultural safety was scaffolded for various settings.

This document provides a preparation and performance guide for aspiring military band saxophonists to aid them in their preparation of the ten most requested excerpts for the premier military bands of the United States from auditions that occurred between 2003 and 2023. Despite being a popular career path for saxophonists, no such document like this exists to help saxophonists in their audition preparation. This document was inspired by a common misconception that only “perfect” auditions win these types of positions, which is not accurate. Inspired by The Richtmeyer Method for Saxophone Mastery, this project aims to help prospective auditionees discover the deeper artistry needed to win one of these positions. A chapter establishing how to practice and internalize the frameworks and fermata practice strategy seen in each excerpt using common scales and patterns is included along with a chapter using Richtmeyer’s practice strategies for stylizing marches, which are the backbone of military music and used in many auditions. The discussion of each excerpt is divided into the following sections: History, Stylistic Considerations, Frameworks for Developing Style, Technical Challenges, Technical Exercises and Conclusion. Furthermore, this document includes an exploration of the lineage of the saxophone from the French military bands to the American military bands and includes a brief examination of the current state of the ten premier bands and their respective roles in military music in the United States.

The Pittsburgh Regional Healthcare Initiative (PRHI) is an innovative model for health system change based on regionwide shared learning. By linking patient outcomes data with processes of care and sharing that information widely, PRHI supports measurable improvements in regionwide clinical practice and patient safety. In addition, through the redesign of problem solving at the front lines of care, PRHI helps health care organizations to evolve toward becoming sustainable systems of perfect patient care. This paper describes PRHI's design for change, reviews the progress and limitations of the shared learning model, and offers a set of broader policy considerations. [PUBLICATION ABSTRACT]

Von Willebrand factor (VWF) is a multimeric haemostatic protein comprised of a series of repeat domains. It is responsible for platelet adhesion to the site of vessel injury, binding to collagen exposed by injury and to platelets by glycoprotein Ibα (GPIbα). It also acts as a carrier for coagulation Factor VIII (FVIII), increasing its half-life in circulation and localising activated FVIII to the site of injury. Synthesised primarily in the endothelial cells, VWF multimers are either released constitutively into the bloodstream or ultra-large multimers are stored in the endothelial cell cytoplasm in cylindrical storage granules, Weibel-Palade bodies. The importance of VWF function on maintaining normal haemostasis is demonstrated by the quantitative and qualitative defects exhibited by von Willebrand disease (VWD), the most common inherited bleeding disorder in the world. Type 1 VWD is most common, caused by specific mutations throughout the multimeric protein and characterised by reduced levels of circulating VWF. Of the 6 C-terminal C domains of VWF, C3 contains the most VWD Type 1 causing mutations. Whilst the molecular structures of other domains which comprise the collagen, GpIbα and FVIII binding sites are well characterised, the C domain structures remain largely unsolved. This thesis presents the structure of the VWF C3 domain solved using nuclear magnetic resonance spectroscopy and the effect of specific disulphide bond mutations on the domain structure. The C3 domain is comprised of two distinct subdomains - SD1 and SD2. SD1 is dominated by two β-sheet structures whilst SD2 comprises a single β-sheet structure. Domain stability is maintained by five disulphide bonds, two in each subdomain and the inter-subdomain relationship preserved by a single disulphide bond connecting the two. Mutations of each individual disulphide bond resulted in incomplete folding of the domain, highlighting their importance in maintaining the structural integrity of the C3 domain.
