Published: April 2023

Abstract
In this paper, we detail how damage mechanisms commonly found on marine terminal structures and process equipment can be automatically detected using a machine learning (ML) pipeline. Defects in its varied forms, such as corrosion, steel, wood and concrete damages must be closely monitored in offshore oil and gas platforms and also in marine terminals; the cost of not monitoring and detecting defects can range from unplanned shutdowns, plant damage, to human fatalities. On-site inspection of defects is labor intensive and require frequent travel to offshore and onshore facilities. This process has two shortcomings: firstly, it is costly involving man hours spent on the facility and secondly only a subset of the total defects is monitored during each inspection due to difficulty in obtaining full coverage; specially in this scenario a high-risk defect could be missed completely. We use marine terminals as an example of how defects can be detected using machine learning techniques, however the pipeline for generating the ML models could be extended to other types of defects and structures. Significantly, the output from our ML pipeline can be used as an input to the Risk Based Inspection (RBI) system assisting asset operators in their inspection and maintenance planning. Furthermore, digitized inspections and ML can provide around 95% coverage of the terminal while avoiding problems faced by a human inspector such as producing consistent results across inspections and sites.
Our system captured terrestrial spherical imagery and range data (LIDAR), subsea imagery, sonar, and ultrasonic thickness (UT) gauge data using different sensors and equipment on a marine terminal. Equipment used in our data-capture included an unmanned aerial vehicle (UAV), a terrestrial scanner, a remotely operated vehicle for underwater imaging (ROV) and a remotely operated surface vehicle (ROSV). For the purposes of this work, we used the images captured by the terrestrial scanner. We built an automated defect detection pipeline using state of the art machine learning and artificial intelligence (AI) tools taking the cube face images as inputs. The defect detection pipeline was trained with examples of defects labeled by asset integrity engineers to ensure quality of results. We built the pipeline to detect damage mechanisms for steel and wooden structures, however our system could be scaled to incorporate other types of defects and structures. Our AI pipeline was able to achieve a high level of accuracy identifying wood damage with a mean-Average Precision (m-AP) of 0.80 and steel damage with a m-AP of 0.84, where a m-AP of 1.0 indicates perfect detection of damage.
Labrador Gas – History and Opportunity
Authors: King Tony , Gillis Erin 
Published: April 2023

Abstract
Exploration in the 1970s and early 1980s identified approximately 4.2 TCF of natural gas and 123 million barrels of natural gas liquids on the Labrador Shelf within the Hopedale and Saglek basins. At the time, development was deemed unfeasible due to insufficient reserves and the threat posed by icebergs. Subsequent work has shown the original iceberg risk analysis to be very conservative. An iceberg risk model was developed to update the previous analysis and additional data was collected through a series of field programs. This resulted in a large multibeam mosaic covering the Makkovik Bank and pipeline landfall at Cape Harrison, and the development of a large iceberg scour database. An alternate landfall has also been identified at Cartwright with lower iceberg risk than the originally selected site.
In 2010, the Oil and Gas Corporation of Newfoundland and Labrador (OilCo) undertook a regional oil seep mapping and interpretation study covering all offshore Newfoundland and Labrador, to help identify areas of interest with active petroleum systems. Based on these results, from 2011 to 2020 Oilco acquired 2D and 3D long offset broadband seismic datasets targeting the Chidley Basin, in the slope and deepwater off Labrador. This data has been used to map and quantify potential hydrocarbon systems within the basin. In 2021, Beicip-Franlab conducted a resource assessment on behalf of OilCo, based on available geological and geophysical data from the Chidley Basin. As reported in "Offshore Newfoundland & Labrador Resource Assessment, Labrador South NL-CFB03", "results show the very likely occurrence of a working petroleum system in the Chidley Basin capable of efficiently generating and preserving liquid and gas hydrocarbons in the slope and deepwater basin". Hence, the probability of additional resources to increase the total reserves available to support a gas development is considered high. If exploration drilling confirms the presence of gas, then the total gas available for development will include the original 4.2 TCF and any new reserves. Hence, the two barriers originally identified to the development of Labrador gas (iceberg risk and gas reserves) may be resolved.
Effect of Shared Anchor System for a Floating Offshore Wind Project on Reductions in CO2 Emissions
Authors: Lee Junho , Aubeny Charles P 
Published: April 2023

Abstract
The trend of the offshore wind industry is expected to shift from fixed towers in shallow water to floating platforms in deeper water due to factors such as wind resource consistency and local seafloor bathymetry. The floating offshore wind industry requires cost-effective anchor alternatives suitable to a range of mooring types, water depths, geological locations, and environmental conditions. One attractive and cost-effective anchor solution can be the shared anchor system, with multiple mooring lines attached to a single anchor. Previous preliminary studies indicate that the shared anchor system provides significant capital cost savings due to its multiline potential resulting in reductions in required anchor footprints and logistic efforts. While they provide valuable insights into anchor performance and its cost-saving effect, these studies did not address the environmental impact in view of greenhouse gas emissions. This spurs the current study to estimate the effect of the shared anchor systems on reductions in CO2 emission. Firstly, this paper compares envisioned shared anchor systems, such as a suction anchor, a deeply embedded ring anchor (DERA), and a skirt, from optimal design standpoints. Secondly, embodied carbon in steel-based anchor alternatives is computed using a carbon calculator tool based on standardized data and compared to each solution. Lastly, the study carries out a comparative study on how anchor transportation from the factory to the construction site affects CO2 emission. The findings from the study provide a platform to select the shared anchor system considering cost reductions and estimate the environmental effects, which is a key consideration to Green Construction. The results show that the DERA is a cost-effective and environmental-friendly alternative for the floating offshore wind project.
A Comparison of the Increase in Capacity with Time for Normally and Overconsolidated Clays
Authors: Stevens Robert F. 
Published: April 2023

Abstract
This paper presents new findings not observed from the field blow counts alone for normally and overconsolidated clays. Refined analyses, including the Case Method and signal matching, show subtle differences in the driving behavior. Examples presented for normally consolidated clays are the driving of 30-in.(0.76-m)-diameter open-ended pipe piles, 14-in.(0.35-m)-square precast prestressed concrete piles, and 14HP73 H-piles. Examples are also presented for 48-in.(1.22-m)-diameter open-ended pipe piles driven in heavily overconsolidated clay. The shaft resistance and end bearing decrease with every hammer blow applied to the piles redriven in the normally consolidated clay profiles but were generally constant for the heavily overconsolidated clay profile. Set-up factors observed in the normally consolidated clay were 4.3 after a delay of 3.7 days for the 30-in.(0.76-m)-diameter pipe piles, and 3.3 after a delay of 4.7 days for the 14-in.(0.35-m)-square precast prestressed concrete piles. Set-up factors observed in the overconsolidated clay were 1.7 after a delay of one day, 1.8 after a delay of 5 days, 1.9 after a delay of 13 days, and 2.0 after a delay of about 15 days. The shaft resistance did not increase after a delay of one day but did increase for longer delays.
Droplet Size and Flow Characterization in Pipe Fittings and Valves (and Why People Keep Making the Same Mistakes)
Authors: Avila Carlos 
Published: April 2023

Abstract
Considerations on droplet size predictions and flow characterization when designing major capital projects and troubleshooting production operations can have a large impact on production system equipment from the wellhead to the oil export line. Areas benefiting from droplet size and flow characterization include improved prediction of flow assurance issues in flowlines such as hydrates and corrosion or separator sizing and interconnecting piping design. Simulations based on Computational Fluid Dynamics (CFD) simulations demonstrate how detailed fluid flow modeling in relatively small geometries can help to make better decisions on large-scale production systems. Characterizing the flow in flowlines, valves, fittings, and inlet piping to separators enables the prediction of the droplets carrying different phases and chemicals. A first group of CFD simulations characterizes the flow inside three different pipe fittings. A second group of CFD simulations compares the flow around the plate of a butterfly valve (and the immediate upstream and downstream pipe sections around the valve) at different openings. The use of refined mesh geometries to capture critical locations in each simulation and selection of proper turbulent models allows for proper calculation of the turbulent dissipation energy. Droplet size calculations were carried out once the turbulent dissipation energy driving the minimum and maximum droplet sizes was obtained. The simulations results include a comparison of previous work on flow characterization pipe fittings such as a long radius elbow, an impacting tee and a blind tee, and recent simulation results comparing the effect of different valve openings for a butterfly valve and their effect on velocities and turbulence and eventual impact on droplet size distribution. The effect on separation performance (quality of outlet streams) is significantly affected by inlet geometry choices (and resulting droplet size distributions) making the difference between a separator able to meet separation specifications or a design that will miss company expectations and regulatory requirements. Flow characterization and droplet size prediction can help the proper scale-up from experimental tests to large field applications. Simple solutions including smarter piping design upstream of separators and improved flow assurance assessments can have a large impact on improving overall production system efficiency and reliability. Development of improved guidelines that include the use of flow characterization will prevent repeating design mistakes.

Introduction:
Shoulder capsulitis (SC) is a common musculoskeletal complication in patients with diabetes. It can be particularly disabling. It is often overlooked by clinicians. The aim of this study is to evaluate the prevalence of retractile capsulitis and to identify the risk factors in a population of Moroccan diabetic patients.

Materials and Methods:
We realised a cross-sectional study including patients with diabetes mellitus (DM). We recorded the demographic and diabetic characteristics of our patients. SC and vascular complications were assessed by clinical and para-clinical investigations. The prevalence of SC was calculated. The factors associated with SC were evaluated by suitable statistical tests.

Results:
Three hundred and Sixty-five patients were included; 84.9% had Type 2 DM (T2DM). The mean age of the participants was 52.6 ± 13.6. Shoulder capsulitis was present in 12.6% of patients. In statistical analysis, age >50 years (P = 0.001), T2DM (P = 0.03), duration of progression >10 years (P = 0.03), dyslipidemia (P = 0.013) and macrovascular complications (P = 0.009) were associated with an increased frequency of SC.

Conclusion:
This study shows that the prevalence of SC is higher in diabetic patients. Therefore, inclusion of this pathology in the global management of the diabetic patient is necessary.

ABSTRACT.
Prior to 2018, malaria therapeutic efficacy studies (TESs) in Nigeria were implemented separately at different sites, as assigned by the National Malaria Elimination Program (NMEP). In 2018, however, the NMEP engaged the Nigerian Institute of Medical Research to coordinate the 2018 TESs in 3 of 14 sentinel sites with the objective of standardizing their conduct across all three sites: Enugu, Kano, and Plateau states in three of six geopolitical zones. Artemether–lumefantrine and artesunate–amodiaquine, the two first-line drugs for treatment of acute uncomplicated malaria in Nigeria, were tested in both Kano and Plateau states. In Enugu State, however, artemether–lumefantrine and dihydroartemisinin–piperaquine were the test drugs, with dihydroartemisinin–piperaquine being tested for potential inclusion in Nigerian treatment policy. The TES was conducted in 6-month to 8-year-old children and was funded by the Global Fund with additional support from the WHO. A multipartite core team comprised of the NMEP, the WHO, the U.S. Presidential Malaria Initiative, academia, and the Nigerian Institute of Medical Research was set up to oversee the execution of the 2018 TES. This communication reports best practices adopted to guide its coordination, and lessons learned during in the process, including applying developed standard operating procedures, powering the sample size adequately for each site to report independently, training the investigating team for fieldwork, facilitating stratification of decisions, determining efficiencies derived from monitoring and quality assessment, and optimizing logistics. The planning and coordination of the 2018 TES activities is a model of a consultative process for the sustainability of antimalarial resistance surveillance in Nigeria.
The New Apostolic Reformation, Trump, and Evangelical Politics
Authors: Berry Damon T. 
Published: April 2023

Whilst many assume that conservative evangelical support for Trump is motivated by his position on social issues such as abortion and LGBTQ rights, or a nostalgia for an imagined American golden age, this book shows that the reality is much more complex by looking at a more recent and understudied trend of Evangelicalism in America.
Damon T. Berry examines how leaders within the New Apostolic Reformation (NAR), a charismatically inclined Evangelical movement, claim their support for Trump came from alleged prophetic visions that compelled them to defend Trump’s candidacy, and to continue to defend his presidency, re-election against demonically inspired, Marxist, “Deep State” enemies. In this conspiratorial cosmology, spiritual warfare through prayer and political activism is the duty of the faithful so that they might protect Trump as God’s anointed leader and war against malevolent, unpatriotic forces that oppose him, the nation, and God himself.
Working from primary source materials produced by leading figures among the NAR, Berry argues that this conspiratorial discourse is central to NAR support for Trump’s candidacy, presidency, and re-election effort, and that this discourse has come to shape some of the most important debates among American religious conservatives in the 21st century.
Queer Approaches in Musical Theatre
Authors: Donovan Ryan 
Published: April 2023

Queer Approaches in Musical Theatre introduces readers to a facet of musicals often assumed but misunderstood: how queer approaches in musical theatre extend deeper than fabulosity. Queerness in musicals challenges heteronormativity but sometimes simultaneously reinforces it.
This volume encompasses queerness beyond simply the familiar narrative of gay men’s over-representation in musical theatre. Readers will be introduced to the history of queerness in musicals as well as queer methods of how to study musicals. Featuring four case studies, centered around musicals such as The Book of Mormon, Fun Home, Everybody's Talking About Jamie and La Cage aux Folles, readers will discover the historical contexts, textual narratives, staging, and reception of these influential productions.
Published as part of the Topics in Musical Theatre series, this foundational book provides readers with an understanding of the historically shifting terminology of queerness as well as offering a brief overview of how queer theory informs the study of musicals themselves.
Race in American Musical Theater
Authors: Lee Josephine 
Published: April 2023

While most discussions of race in American theatre emphasize the representation of race mainly in terms of character, plot, and action, Race in American Musical Theatre highlights elements of theatrical production and reception that are particular to musical theatre. This introductory book examines how race functions not only through the recurrence of particular character types and storylines, but also in musical style and song lyrics, in the staging of the chorus line, and in the use of cross-racial casting.
Each chapter identifies a particular set of questions that encourages readers to look at works of musical theatre more critically and place them in a broader historical and social context. Drawing on problematic examples such as Thoroughly Modern Millie and Miss Saigon through to integrated shows such as Dreamgirls, Bring in Da Noise, Bring in Da Funk and Hamilton, it serves as a critical survey and analysis of the topic within the American musical theatre canon.
Published within the Topics in Musical Theatre series, this volume also includes an appendix that provides background information and plot summaries for its key examples and a list of additional readings related to the topic.
The Improv Illusionist
Authors: Raitt David 
Published: April 2023

Object work, environment and physicality are essential for improvisational theatre. Skilled improvisers can draw audiences into the performance by helping them see things that aren’t there.
The Improv Illusionist is the first book dedicated to physical improv. It reveals why these skills are so important, how to fix bad habits that develop over time and practical techniques for being more physical on stage.
The book features over 50 exercises to help improvisers develop their skills through solo and group work.
Improvisers of all ages and experience levels will learn how to:
* become more playful through exploring physical activity;
* eliminate miscommunication with other players by adding precision to object work;
* get new ideas for scenes by exploring the environment and activities;
* develop an eye for real-world detail and how to reproduce it in improv;
* add more visual flair to scenes;
* stay safe, both physically and emotionally, in shows, rehearsals and classes
Even the most seasoned improv performers often struggle to be more physical, so this book fills an important niche in improv actor training.
Realist Film Theory and Bicycle Thieves
Authors: Neroni Hilary 
Published: April 2023

The Film Theory in Practice series fills a gaping hole in the world of film theory. By marrying the explanation of a film theory with the interpretation of a film, the volumes provide discrete examples of how film theory can serve as the basis for textual analysis. Realist Film Theory and Bicycle Thieves offers a concise introduction to realist film theory in jargon-free language and shows how this theory can be deployed to interpret Vittorio De Sica’s 1948 Italian neo realist masterpiece Bicycle Thieves.
Hilary Neroni explores the original realist film theorists from the 1940s: André Bazin, Siegfried Kracauer, and Cesare Zavattini, among others. But rather than seeing realist film theory as simply a theory of the past to be moved beyond, the book argues that the prevalence of realism in many different forms within practice and theory suggests the importance of updating this original realist film theory with an understanding of realism that would sustain its viability. Throughout the book, Neroni analyzes neorealist film movements—such as Italian Neorealism, Parallel Cinema of India, and the Iranian New Wave—that challenge mainstream realism with a more radical form that exposes the social order instead of hiding it. Her in-depth investigation of Bicycle Thieves provides a realist methodology that reveals the radicality of its combination of realist techniques, a melodramatic story, and humanist values.
Stratospheric temperature measurements from nanosatellite stellar occultation observations of refractive bending

Abstract. Stellar occultation observations from space can probe the stratosphere and mesosphere at a fine vertical scale around the globe. Unlike other measurement techniques like radiosondes and aircraft, stellar occultation has the potential to observe the atmosphere above 30 km, and unlike radio occultation, stellar occultation probes fine-scale phenomena with potential to observe atmospheric turbulence. We imaged the refractive bending angle of a star centroid for a series of occultations by the atmosphere. Atmospheric refractivity, density, and then temperature are retrieved from the bending observations with the Abel transformation and Edlén's law, the hydrostatic equation, and the ideal gas law. The retrieval technique is applied to data collected by two nanosatellites operated by Terran Orbital. Measurements were primarily taken by the GEOStare SV2 mission, with a dedicated imaging telescope, supplemented with images captured by spacecraft bus sensors, namely the star trackers on other Terran Orbital missions. The bending angle noise floor is 10 and
30 arcsec for the star tracker and GEOStare SV2 data, respectively. The most significant sources of uncertainty are due to centroiding errors due to the fairly low-resolution stellar images and telescope pointing knowledge derived from noisy satellite attitude sensors. The former mainly affects the star tracker data, while the latter limits the GEOStare SV2 accuracy, with both providing low vertical resolution. This translates to a temperature profile retrieval up to roughly 20 km for both star tracker and GEOStare SV2 datasets. In preparation of an upcoming 2023 mission designed to correct these deficiencies, SOHIP, we simulated bending angle measurements with varying magnitudes of error. The expected maximum altitude of retrieved temperature is 41 km on average for these simulated measurements with a noise floor of 0.39 arcsec. Our work highlights the capabilities of stellar occultation observations from nanosatellites for atmospheric sounding. Future work will investigate high-frequency observations of atmospheric gravity waves and turbulence, mitigating the major uncertainties observed in these datasets.
