Abstract Background Birth cohort screening of chronic hepatitis C (CHC) is recommended in British Columbia since 2018 for baby boomers born between 1945 to 1964, with an estimated provincial prevalence of 2.31%. Though there remained a gap in care following anti-hepatitis C positivity, resulting in reflexive ribonucleic acid (RNA) testing provincially. Dual screening of CHC in patients referred to colorectal (CRC) screening programs can provide an opportunity to link patients with healthcare professionals to ensure appropriate follow-up. Purpose We aimed to assess the uptake of CHC screening amongst CRC screening patients after the release of British Columbia’s birth cohort guidelines, both pre and post-COVID-19 pandemic. Method A retrospective review of patients referred to a CRC screening program in Vancouver from October 1st to December 31st, 2019, and December 1st – 31st, 2021, was performed. Collected data included demographics, liver disease history, and co-infection rates with hepatitis B (HBV) or human immunodeficiency virus (HIV). Dates of first-time hepatitis C antibody, RNA and viral load testing were gathered. Descriptive statistics were used to identify the proportion of screening and prevalence of CHC. Result(s) A total of 553 patients were referred for colonoscopy to the CRC screening program, of whom 458 (82.8%) patients were born between 1945 to 1964, and 273 (n=49%) were female. Among the 250 (45.2%) patients screened for CHC, 4 (0.72%) had positive anti-hepatitis C, all of whom were baby boomers. In 2019, 44% (n=183) of patients were screened for CHC; 78.7% (n=144) were screened before colonoscopy referral. In 2020, 48.6% (n=67) of patients were screened for CHC; 100% of cases were screened before colonoscopy referral. Conclusion(s) Birth cohort screening of CHC is underutilized in British Columbia. Dual screening of CHC at the time of referral to CRC screening provides a practical approach to linking patients to healthcare.

Full textAbstract:
This study investigated the incidence of failure after locking compression plate (LCP) osteosynthesis around a well-fixed stem of periprosthetic femoral fractures (PFFs). We retrospectively evaluated outcomes of 63 Vancouver type B1 and C PFFs treated with LCP between May 2001 and February 2018. The mean follow-up duration was 47 months. Only patients with fracture fixation with a locking plate without supplemental allograft struts were included. We identified six periprosthetic fractures of proximal Vancouver B1 fractures with spiral pattern (Group A). Vancouver B1 fractures around the stem tip were grouped into seven transverse fracture patterns (Group B) and 38 other fracture patterns such as comminuted, oblique, or spiral (Group C). Vancouver C fractures comprised 12 periprosthetic fractures with spiral, comminuted, or oblique patterns (Group D). Fracture healing without complications was achieved in all six cases in Group A, 4/7 (57%) in Group B, 35/38 (92%) in Group C, and 11/12 (92%) in Group D, respectively. The failure rates of transverse Vancouver type B1 PFFs around the stem tip were significantly different from those of Vancouver type B1/C PFFs with other patterns. For fracture with transverse pattern around the stem tip, additional fixation is necessary because LCP osteosynthesis has high failure rates.

Full textAbstract:
ABSTRACT Cryptococcus neoformans is a human fungal pathogen that exists as three distinct varieties or sibling species: the predominantly opportunistic pathogens C. neoformans var. neoformans (serotype D) and C. neoformans var. grubii (serotype A) and the primary pathogen C. neoformans var. gattii (serotypes B and C). While serotypes A and D are cosmopolitan, serotypes B and C are typically restricted to tropical regions. However, serotype B isolates of C. neoformans var. gattii have recently caused an outbreak on Vancouver Island in Canada, highlighting the threat of this fungus and its capacity to infect immunocompetent individuals. Here we report a large-scale analysis of the mating abilities of serotype B and C isolates from diverse sources and identify unusual strains that mate robustly and are suitable for further genetic analysis. Unlike most isolates, which are of both the a and α mating types but are predominantly sterile, the majority of the Vancouver outbreak strains are exclusively of the α mating type and the majority are fertile. In an effort to enhance mating of these isolates, we identified and disrupted the CRG1 gene encoding the GTPase-activating protein involved in attenuating pheromone response. crg1 mutations dramatically increased mating efficiency and enabled mating with otherwise sterile isolates. Our studies provide a genetic and molecular foundation for further studies of this primary pathogen and reveal that the Vancouver Island outbreak may be attributable to a recent recombination event.

Background and purpose: The Lubinus SP2 stem has been associated with a very low risk of periprosthetic femoral fractures (PPFFs). We aimed, primarily, to study the radiographic morphology of PPFFs close to a Lubinus SP2 stem. Secondarily, we analyzed whether higher reoperation rate was correlated to the revision method chosen or to the characteristics of the fracture and of the bone.Patients and methods: The study included 156 femoral fractures close to a Lubinus cemented stem. These fractures were treated in 40 hospitals in Sweden between 2006 and 2011 and were followed up until 2019. Data from the Swedish Arthroplasty Register was used. Medical records and radiographs were studied. The fractures were classified according to the Vancouver classification. The fracture location and anatomy were delineated. We also measured the remaining attachment index (RAI) and the canal thickness ratio.Results: Vancouver type C (n = 101) and spiral fractures (n = 67, 41 in Vancouver C and 26 in Vancouver B) were the most common fracture types. 4 fractures were avulsion of the greater trochanter. The remaining 51 fractures occurred around the stem (B1: 25, B2: 16, and B3: 10). B fractures were more commonly reoperated on (18 of 51, 35%) than type C fractures (11 of 101, 11%, P = 0.001). In most femurs with type B3 fracture, the fracture line covered an area only around the stem, but in all B1 and in 11 of 16 B2 fractures, it was extended even distal to the stem. ORIF instead of stem revision in B2 fractures, use of short stems or plates, and inadequate reduction of the fractures were risk factors for subsequent reoperations.Conclusion: The higher reoperation rate in type B fractures, compared with fractures distal to the stem, could be caused by their higher degree of complexity and reduced capacity for healing in the region around the stem.

Abstract This study looks at the emergence of newspaper sport cartooning in the early twentieth century through a comparison of the parochial images of Vancouver British Columbia cartoonist James Fitzmaurice and the syndicated American sports cartoons of Robert Ripley. The study examines the working lives of the best known American sport cartoonists and then focuses on the work of Vancouver Province staff cartoonist James B. Fitzmaurice during the prewar period and how these images grew out of local experience. With the arrival of the syndicated sports cartoons of New York City cartoonist Robert Ripley in 1914, Vancouver readers are given “world of sport” images that differed from the more eclectic visual meanings tied to local experience that characterized Fitzmaurice’s work. This study suggests that the contrast between Fitzmaurice and Ripley marks the difference between two levels of sport culture consumption and that visual culture acted as an important conduit for the growth of shared international sport consciousness.

Introdução: As fraturas periprotéticas de quadril são uma complicação grave e com elevado índice de morbimortalidade observadas após abordagens cirúrgicas, como artroplastia de quadril e cirurgias de revisão. Ocorrem mais frequentemente ao redor do componente femoral em relação ao acetabular. Essa complicação está relacionada a fatores que são avaliados por meio do sistema de Vancouver, possibilitando definir a melhor forma de abordagem e cuidados da complicação. Apresentação do caso: Paciente do sexo feminino, 60 anos de idade, admitida no Hospital Universitário Risoleta Tolentino Neves (UFMG), com uma fratura tipo A, que tem localização trocantérica e pode se manifestar no trocanter femoral maior ou menor. Discussão: Com o aumento da longevidade, a idade média da população vem aumentando, e com isso o número de intervenções cirúrgicas também aumentam, principalmente as artroplastias de quadril. O que leva a um maior número de situações que envolvem complicações pós-cirúrgicas. Com mais episódios de fraturas periprotéticas, torna-se importante uma melhor avaliação dos quadros para melhor conduta e elucidação de eventuais complicações. Conclusão: Ao se constatar uma fratura periprotética de quadril, deve-se classificar a mesma seguindo o sistema de Vancouver que é dividido em três tipos A, B e C. Essa classificação vai ditar como será a abordagem mais assertiva para resolução do quadro do paciente

Full textAbstract:
In North America, why and how municipalities in large metropolitan areas cooperate is a pressing question. Both in Canada and the United States, the literature has been greatly influenced by the public choice views that rational actors have very limited rational or economic incentives to cooperate unless the state steps in to rule cooperation. But beyond the ideological debate, these views are about issues of regional cooperation public choice (polycentrism); (3) metropolitan governance (new regionalism); and (4) rescaling and re-territorialization, which are tightly linked to value systems where: a) metropolitan government centers on monocentric efficiency; b) public choice on polycentric efficiency; c) metropolitan governance on equity and competitiveness; and d) rescaling and re-territorialization centers on global competitiveness. These discussions set the stage for this paper's main argument: in North America, the Greater Vancouver Regional District is an exemplary commitment to metropolitan cooperation.Spanish En Norteamérica esta emergiendo una pregunta urgente: ¿por qué y cómo cooperan los municipios de las grandes áreas metropolitanas? En Canadá y Estados Unidos, la literatura ha sido fuertemente influenciada por la teoría del public choice, según la cuál los actores racionales tienen muy escasos incentivos racionales o económicos para cooperar, a menos que el estado intervenga y ordene la cooperación. Obviamente, más allá del debate ideológico, estas visiones abordan asuntos de cooperación regional desde varias perspectivas normativas: (1) el gobierno metropolitano (antiguo regionalismo); (2) public choice (policentrismo); (3) gobierno metropolitano (nuevo regionalismo); y (4) reorganización escalar y re-territorialización, transformaciones que se conectan estrechamente al sistema de valores donde: a) el gobierno metropolitano se centra en la eficiencia monocéntrica, b) la public choice sobre la eficiencia policéntrica, c) la gobernanza metropolitana en la equidad y la competitividad, y d) la reorganizacion escalar y reterritorialización se enfoca sobre competitividad global. Estas discusiones preparan el escenario para el principal argumento de este artículo: en Norteamérica, el Gran Distrito Regional de Vancouver es probablemente un compromiso ejemplar de cooperación metropolitana.French En Amérique du Nord une question pressante se pose, à savoir pourquoi et comment les municipalités des grandes métropoles coopèrent. Tant au Canada qu'aux États-Unis la li érature a été fortement influencée par la théorie du choix public, selon laquelle les acteurs rationnels ne trouvent que très peu d'incitations rationnelles ou économiques qui les incitent à coopérer, à moins que l'État n'intervienne pour ordonner la coopération. Il est toutefois évident que, derrière le débat idéologique, ces débats abordent les questions de coopération régionale à partir de différentes perspectives normatives, (1) le gouvernement métropolitain (ancien régionalisme), (2) le choix public (polycentrisme), (3) la gouvernance métropolitaine (nouveau régionalisme), et (4) la réorganisation scalaire et la reterritorialisation, des transformations qu'elles relient étroitement à des systèmes de valeurs, où : a) le gouvernement métropolitain se centre sur l'efficacité monocentriste, b) le choix public sur l'efficacité polycentriste, c) la gouvernance métropolitaine sur l'équité et la compétitivité, et d) la réorganisation scalaire et la reterritorialisation se focalisent sur la compétitivité globale. Ces discussions forment la toile de fond du principal sujet de cet article : en Amérique du Nord, le Greater Vancouver Regional District constitue probablement un compromis exemplaire en matière de coopération métropolitaine.

Full textAbstract:
A new set of urban design requirements is proposed to replace the current urban design guidelines for the B. C. Place site in Vancouver, B. C. The site is 90.6 hectares of open area, contiguous to the downtown, it is the subject of extensive planning activities. The site has been chosen because it is free of most of the typical impediments that constrain urban planning in more congested areas of the city. Accordingly, a new way of expressing urban space is appropriate.
To be valid urban design requirements must be conceived with a purpose in mind. The purpose, here, is the essential element of urban design, a shared vision of urban space. It must define, within a broad public consensus, a set of urban design requirements communicating, over an extended time period, a consistent vision of urban space.
Six urban design requirements are set out to implement a shared vision of urban space. They have been reduced to a minimum to provide as much freedom of expression to the design professions as possible. They are under six headings: Interim Land Use, Site Development, Physical Form and Design, Environment, Occupancy, and Movement.
Pivotal in the composition of the urban design requirements is an instrument called the Orthodox Surface Modulator, augmented by a Check List of architectural design elements. Together they become a metaphoric framework of reference, a part of the creative process within the development control system.
The Orthodox Surface Modulator, as it is applied, describes the volumetric forms of building envelopes and the public urban spaces between buildings. It describes buildings and spaces to enhance public amenity. It may, under specific environmental circumstances, mitigate undesirable site conditions by describing building envelopes as buffer buildings, shielding passive urban space from noise and distractions.
Urban Space is discussed. A Shared Vision of Urban Space, how it is evolved by public discourse, and a proposed Theory of Urban Space is explained. A critique of current urban development on Burrard Street, Vancouver, between Georgia Street and the waterfront explains why the present urban design guidelines, transfer of development rights and bonusing, have failed to produce the intended urban spatial amenity.
Urban design requirements are not a new phenomenon. Only since the early 1970s have they taken on their present complex form in the City of Vancouver. A brief historic outline traces the antecedents of the proposed urban design requirements, placing them in context from early Greek attempts to rationalize optical distortion to the present day.
The proposed application of the six urban design requirements and the Surface Modulator would be mandatory. The manner in which the elements of the Check List are integrated into the matrix of the Surface Modulator is proposed to be discretionary. The complete set of urban design requirements are intended to be used in a negotiating procedure common in planning practice.Applied Science, Faculty of

Full textAbstract:
Almost all of British Columbia, 95%, is public land, managed by the B.C. government.
This "95/5 split" is unique in the industrialized world. Public land, in its use for forestry, oil
and gas, mining, tourism, and agriculture, remains the foundation of the B.C. economy. It
has also come to define how the people of British Columbia see themselves as a society. But
when did land become so much a part of British Columbia's identity? How is it that so
much of British Columbia remains public? What does the high proportion of public land tell
us about the role of the government? Why does land continue to have such an important
role in this modern society? And what role does law play in the relationship among society,
the economy, land, and government?
With these questions as its starting point, this thesis offers a history of British Columbia
through the lens of legislation for the allocation of land. The period covered, 1858-1978,
enables the study of the two major periods of transition in land law, and of the continuity
between them. Those periods are the establishment of colonial land legislation, from 1858-
1871, and the upheaval of those laws, from 1965-1978, ending just before the era of
provincial land-use planning. A close study of these two periods, and of the themes
apparent in the changes to the legal regime between 1871-1965, allows the thesis to ask
questions about the role of law itself: Is law merely a tool of economic and political actors, or
does it play an instrumental role of its own in structuring society? This thesis argues that, in
the context of B.C. land legislation, law does play such a role, and considers the implications
of this conclusion for those, such as environmentalists, seeking to change society.Law, Peter A. Allard School of

Full textAbstract:
This study examines the manifestations of French humanism in sixteenth-century intellectual culture, through an analysis, for the first time, of the entirety of the works of Pierre Boaistuau. An eminent French humanist writer, on whose life little information exists, Boaistuau emerges far more prolific than any previous study has hitherto recognised. Thus, on a first level, his case offers the opportunity for an exploration of the developments of French print culture at the time. In addition, careful examination of the contents of his widely circulated works sheds new light on the ways humanist themes and values were incorporated into contemporary literary production, and were used for different purposes which surpassed the mere celebration of ancient learning. Boaistuau employed seven genres in order to compile seven books of different natures, all of them however grafted onto a humanist framework. Associated with narrative fiction, Renaissance philosophy, political theory, the study of history, and natural philosophy, his works demonstrate how the classical past and the humanist values of virtue, erudition, and self-discipline were used in a variety of ways in mid sixteenth-century France: for promotion of a moralising message, praise of the French monarchy, bolstering the Catholic faith, and enhancing the understanding of the natural world.

Full textAbstract:
Most recent studies of religion and society have focussed on the period from c. 1880 to 1914, basing their investigations upon late-Victorian newspaper censuses of churchgoing. This thesis aims to study the development of religion in its economic and social context in a large northern industrial parish over a longer period of time from c. 1740 to 1914. In religious terms this period extends from the mid-eighteenth century Evangelical Revival to the decline of organised religion in the early twentieth century. In economic and social terms the period is characterised by the transformation of the parish from a semi-rural, proto-industrial society dominated by a relatively small but expanding market town, into a predominantly urban advanced industrial society dominated by a medium-sized textile manufacturing town and several smaller urban centres of textile production; supporting a wide diversity of associated industries and trades, but still containing within its boundaries sharply contrasting urban and semi-rural environments. The thesis aims to assess how religious expression within the parish of Halifax was affected by the changing economic and social environment, in particular the urban-industrial experience, and how religion helped shape the new urbanindustrial society during the period from the middle of the eighteenth century to the outbreak of the First World War. It argues that whilst the pessimistic view of a moribund Georgian Church of England can no longer be sustained by the Halifax evidence, the Established Church nevertheless lacked the logistical resources to respond effectively to the new urbanindustrial society as it emerged within the parish in the lateeighteenth and early-nineteenth centuries, providing an opportunity for the growth of Evangelical Nonconformity, especially Methodism. It maintains that Evangelical Nonconformity and an Anglican Church renewed by Evangelical incumbencies during the period 1790-1827 and reformed as a consequence of national legislation in the 1840s played a vital role within the expanding urban-industrial society, surviving the experience of industrialisation and urbanisation and displaying a remarkable vibrancy, despite underlying downward trends in churchgoing in the late-Victorian era. It suggests that the causes of the decline of organised religion during this period were complex, but related more to the onset of industrial-urban stagnation and decline than to the experience of industrial-urban expansion.

Twentieth Century Americans witnessed the construction of numerous massive dams that controlled the flow of rivers across the country. Many of these dams were built by the U.S. Army Corps of Engineers to improve navigation and to provide inexpensive electricity and flood control. This paper will seek to shed light on Georgia’s current water crisis by analyzing the initial purposes behind the building of Buford Dam in North Georgia, investigating how water supply issues were addressed in the first half of the twentieth century, and exploring how expectations of the Chattahoochee River changed over time due in part to metropolitan Atlanta’s population growth. This paper will show that Atlanta area leaders secured appropriations for Buford Dam primarily to obtain a reliable water supply and additional electricity for their burgeoning community.

Full textAbstract:
Sir George Grey (1812-1898) served as Governor of South Australia, of New Zealand twice, and of the Cape Colony. This thesis explains his policy for the first time for a history of the political ideas of colonization. Grey introduced the policy of racial amalgamation to settler colonies after the 1837 Report of the Select Committee into Aboriginal Affairs, that had advised the policy of segregation as had been North American policy under Sir William Johnson. This thesis demonstrates that Grey was a Liberal Anglican who had adopted neo-Harringtonian thought, and who introduced Jeffersonian native policy into British native policy. He practised the strategic theory of Antoine-Henri Jomini, applying it to native policy. Grey captured the monarchical constitution of the empire for what had been a settler policy of dissent to the segregation of indigenes that dated back to Tudor Ireland and early Viginia. Grey's distinctive intellectual practices were ethnograpical research and speculation, for which he enjoyed an international reputation, and the constitutional design of settler colonies, an activity he came to totally identify with. The thesis concentrates on his first New Zealand governorship (1845-53) and upon the resumption of his second New Zealand governorship (1861-68) because it was in that colony he first fully practised his native policy and participated in constitutional design, and into which he brought about a crisis of indigenous amalgamation on the eve of the Waikato War in 1863, having introduced full responsible government.

The Church, first organized in 1830, did not organize the Quorum of Twelve Apostles until 1835. When it was organized, Joseph Smith outlined the quorum's responsibilities through revelation. The Twelve were assigned two unique and specific responsibilities: to take the gospel to the nations of the earth and to form a traveling high council for the regulating of the Church outside of its stakes. The first opportunity for the Twelve to fulfill their responsibilities was in May 1835 when they were assigned to travel to the eastern United States and southern Canada. There they both preached the gospel and regulated the branches of the Church. This mission represents not only the first time the Apostles fulfilled their assigned responsibilities but the only time that they filled their responsibilities as an entire quorum. It is surprising that more secondary literature on this mission is not available. This thesis seeks to commence an academic conversation regarding this mission and its impact both on the quorum's development and on the Church in its outlying areas. Chapter 1 details the preparation of the individual members of the Twelve to fulfill this mission. It discusses the preparation of the Twelve prior to their call to the apostleship. It also discusses the training that took place between their call and the commencement of this mission. As an administrative body for the membership of the Church, the Twelve spent the majority of their time on this mission with the members of the Church. Chapter 2 identifies the unique purpose of the Twelve on this mission and how that purpose was fulfilled. Joseph Smith originally laid out the geographic framework for this mission, which sent the Twelve into Canada and throughout much of the northeastern United States. Chapter 3 identifies the locations of the Twelve based on available records and seeks to provide an answer to how the Twelve decided which areas to preach in. Many individuals were baptized during this five-month mission. Chapter 4 identifies what the Twelve taught and the sources that they used. It also discusses the reaction of the people they taught. The concluding chapter summarizes the thesis and identifies areas for further research.

AbstractIn his 1966 John Danz lectures, Francis H. C. Crick decried vitalism in the life sciences. Why did he do this three decades after most historians and philosophers of science regarded vitalism as dead? This essay argues that, by advocating the reduction of biology to physics and chemistry Crick was: (a) attempting to imbue the life sciences with greater prestige, (b) paving the way for bioengineering and the reduction of consciousness to molecules, and (c) trying to root out religious sentiment in the life sciences. In service of these goals, Crick deployed vitalism as a straw man enemy. His wave of so-called vitalists in the middle of the twentieth century in fact raised legitimate questions regarding the relationship of organisms to their DNA molecules that Crick was ill-equipped to answer. Moreover, most were not vitalists at all but advocates for what I term bioexceptionalism—an argument for the methodological utility of keeping biological pursuits within their own domains, distinct from physics and chemistry, regardless of the ontological status of living things. Nevertheless, Crick’s status as a “cross-worlds influencer” entrenched a philosophically-enervated reductionism in the life sciences for decades.

Full textAbstract:
Abstract This paper presents two recent cases studies for high-speed rotating shoes in the East Java Sea of Indonesia where extended reach wells have been successfully drilled and completed. Rotating shoes have been used to successfully deploy 5½ inch lower completion strings in Well A, Well B, and Well C, in 2020, 2022, and 2023 respectively. Well A had the 9⅝ inch casing shoe at 15,492 feet MD with the final depth of 16,480 feet MD. Well B is currently the longest 8½ inch production lateral drilled (6,207 feet) in Indonesia at the time of this paper with a final well depth of 15,685 feet MD. The 9⅝ inch production casing shoe was set at 9,478 feet MD. Well C was eventually completed at a final depth of 14,305 feet MD with 9⅝ inch casing shoe at 10,662 feet MD. All laterals were drilled as 8½ holes and completed as 5½ inch oil producers. In Well A, a rotating shoe was used as a contingency due to its high ERD ratio in comparison to previous wells drilled in the field up until that time. In Well B string rotation was not a feasible option due to well profile and the 5½ inch completions string configuration, hence the need for rotating shoes. In Well C well bore stability issues across zones prone to loss circulation resulted in multiple sidetracks from the primary borehole, one of which was carried in the production section, thus predicating the use of a rotating reamer shoe for the 5½ lower completion. Well C was eventually completed with the third sidetrack, at a final depth of 14,305 feet MD with the 9⅝ inch production casing shoe set at 10,662 feet MD. The liner hanger was successfully set with an estimated savings over $700K for successfully deploying the lower completions Well C as estimated cost of an additional clean-out run. One reason running lower completions in these wells are successful is the use of high-speed rotating shoes. When required the rotating shoe was able to ream through obstructions while guiding the completion string into and through the drilled hole to TD. Rotating shoes are still very new to the industry and adoption is slow. However, from our experience it is evident that deployment requires appreciation of the technology and the underlying principles that make it effective, thus creating an enabling environment for proper application is paramount. This requires collaboration between end-user and supplier with good understanding of well engineering principles because the service provider will be key to a successful operation. This paper focuses on the completion operations leading to the successful deployment of the 5½ inch lower completion strings in both Wells B and C.

Full textAbstract:
The mechanisms responsible for the evolution and rupture of cerebral aneurysms are not well understood. This is a multi-factorial problem, and previous studies [1–3] have identified the major factors involved: a) arterial hemodynamics, b) mechanobiology and wall biomechanics, and c) peri-aneurysmal environment. In this paper we present recent results based on patient-specific computational hemodynamics models of a number of cerebral aneurysms that indicate that hemodynamics plays an important role both in the progression and rupture of intracranial aneurysms. In particular, the data seems to support the idea that mechanisms associated to high wall shear stress may be responsible for the evolution and rupture of these aneurysms [4].

Full textAbstract:
Section 6.5.2 of N283.3-10 of the CSA Standard [1] describes analytical methods for seismic qualification of nuclear components. Clause 6.5.2.2 of this Section instructs how to prepare seismic input for the time history method, specifically it states: “Time-histories of support point motion (displacement, velocity, or acceleration) may be used as dynamic inputs to components. To take into account the effects of possible frequency variations of component and structure, the analysis shall be carried out using three different time-history excitations. These time-histories shall be obtained by varying time scale of the original support point time-history by (a) 1.0; (b) 1 - Δfj/fj; and (c) 1 + Δfj/fj, where fj = the dominant structural frequency; Δfj = a parameter defining the frequency variation due to uncertainties in structural soil properties. The most severe effects obtained from these three time history analyses shall be considered in the design of the components. Notes: (1) A value of 15% for Δfj/fj may be used for the time-history analysis specified in this Clause; (2) For structures directly on bedrock, a value of Δfj/fj = 0% may be used”. This paper identifies some ambiguities in the approach described above. It shows, by theory and examples, that significantly different responses are obtained depending on which form of excitation is used (acceleration, velocity or displacement). In a typical acceleration excitation approach, the response may be over or under estimated. To remove this ambiguity, the paper proposes a simple modification of the broadening procedure described in [1]. The problem discussed in this paper may also be meaningful for the broadening time history described in Appendix N of ASME Code [2].

Full textAbstract:
British Columbia Ferry Services Inc. operates five "C" class passenger-car ferries that were delivered in 1976 (3 ships) and 1981 (2 ships). The vessels have a service speed of 19.0 knots, are 457 ft. long, and have a gross tonnage of 6,550 tons. They have a capacity of about 360 cars and 1,500 passengers. Their route varies from Vancouver-Vancouver Island-Sunshine Coast, with up to 9 round trips per day. The vessels have a double-ended single screw propeller configuration. Each of the controllable pitch propellers are driven by one or two diesel engines rated at 5,930 HP, through single reduction gearboxes. The two gearboxes are connected via quill shafts that are concentric with the pinion shafts. The pinion shafts are engaged via clutches at the end of each of the quill shafts. This arrangement enables one or both of the diesel engines to drive either one or both of the propellers. In 1998 a catastrophic failure occurred to the bull wheel on one vessel. The bull gear teeth broke off taking out both pinions. In 1999 the bull gear on another vessel was replaced as a result of fractured gear teeth, found during an inspection. In addition, a number of failures have occurred to both the lineshaft and pinion shaft bearings. An investigation was conducted to determine the source of the failures and the most prudent and economical course of action. To accomplish these objectives a review of the system design and maintenance/failure history was conducted, as well as theoretical modeling and alignment and vibration measurements. It was found that the failures occurred due to misalignment. A realignment program has been undertaken, with the first realignment completed in February 2002. This paper describes the failure investigation and the results of the realignment work conducted.

Full textAbstract:
This paper reports the results of an experimental investigation of transient, turbulent mixed convection in a vertical channel in which one of the walls is heated and the other is adiabatic. The goal is to simultaneously estimate the constants in a Nusselt number correlation whose form is assumed a priori by synergistically marrying the experimental results with repeated numerical calculations that assume guess values of the constants. The convective heat transfer coefficient “h” is replaced by the Nusselt number (Nu) which is then assumed to have a form Nu = a (1+RiD) b ReDc where a, b and c are the constants to be evaluated. From the experimentally obtained temperature time history and the simulated temperature time history, based on some guess values of a, b, and c, one can define the objective function or the residue as the sum of the square of the difference between experimentally obtained and simulated temperatures. Using Bayesian inference driven by the Markov chain Monte Carlo method, one, more or all of the constants a, b and c are retrieved together with the uncertainty involved in these estimates. Additionally, the estimated parameters are compared with experimental benchmarks.

Full textAbstract:
A nuclear piping system which is found to be disqualified, i.e. overstressed, in design evaluation in accordance with ASME B&PV code, Section III, can still be qualified if further non-linear design requirements can be satisfied in refined non-linear analyses in which material plasticity and other non-linear conditions are taken into account. Our work presented earlier in ICONE16-20 categorized the design rules in the code into linear and non-linear design rules and attempted to clarify the corresponding design requirements. In this paper, an in-depth review of these rules and relevant requirements for time-history dynamic loads designated in Service Limit Levels C and D, such as those caused by e.g. water-hammer effects, is given. In particular, several changes of these rules in the current edition of the codes and their applications are addressed, and several rules which are intensively applied but often found to be inconsistent and confusing in Sweden are discussed. It is suggested that the design evaluation can be made directly through non-linear transient finite element analysis using a strain-based criterion for time-history dynamic loads of either reversing or non-reversing type.

Full textAbstract:
Abstract The field under study is a mature brownfield with no H2S in the fluid stream (PVT) at the time of development. However, concentrations more than 1000 ppm were recorded recently causing wells to shut in (a few already shut). Hence, to bring these wells on stream an assessment of souring potential in the field is required. This paper is the results of our experience in H2S mapping at reservoir-well-facilities modelling, history matching, and prediction of H2S. We will highlight the workflow adopted to find the root causes of souring via sampling and modelling approach since the H2S is measured throughout the field across all the reservoirs, including those undergoing waterflood. Moreover, various options that were studied through simulation will be discussed for mitigation and management of H2S within this field to safeguard the production, and thus recovery of the field. A systematic phased approach is adopted to mitigate and manage the unwanted sour gas (H2S). In the first phase, we performed the analysis of the historical development of H2S throughout the field and developed the concept for possible souring causes. In the second phase, we designed and conducted a comprehensive sampling and laboratory analysis program end-to-end to fill the existing knowledge gap. In the third phase, we performed 3D dynamic reservoir souring modelling where we history matched the H2S and assessed the future potential via forecasting. Finally, we developed multiple mitigation scenarios ranging from nitrate injection, sulphate reducing unit, limiting the nutrient supply for microbe growth via water mixing, etc. It was evident that a) increased injection water contributed to souring wells, b) link between souring wells and nutrient availability, c) increased negative fractioning of a Sulphur isotope as H2S concentration increases, and d) and mesophilic SRBs detected in some souring wells. This evidence suggested that BSR is the predominant cause of souring. It was also seen based on water chemistry that injection water was rich in sulfate while formation water was rich in volatile fatty acids. Results indicate that the nitrate injection (up to 200 ppm) alone may not be an attractive option to mitigate the H2S within this field. However, the combination of SRU and nitrate injection of 150 ppm could be a technically feasible option to mitigate such high concentration of H2S within allowable facilities limits.

Full textAbstract:
Seton Lake is a freshwater fiord located in southwestern British Columbia, roughly 4 km west of Lillooet and 250 km north-northeast of Vancouver. Located in the Coast Mountains, it is an alpine lake about 22-km long and roughly 1-1.5 km wide. It is separated from nearby Anderson Lake, located to the west, by a large pre-historic rock avalanche deposit at Seton Portage. The lake stands at about 243 m above sea level and is up to about 150 m deep (BC gov., 1953). Water level is controlled by a hydroelectric dam (i.e., Seton dam) located at the eastern end of the lake. Here, the lake drains east into Seton Canal, a 5 km diversion of the flow of the Seton River, which begins at the Seton dam. The Seton Canal pushes water to the Seton Powerhouse, a hydroelectric generating station at the Fraser River, just south of the community of Sekw'el'was and confluence of the Seton River, which drains into the Fraser River at Lillooet. Seton Portage, Shalatlh, South Shalatlh, Tsal'alh (Shalath), Sekw'el'was (Cayoosh Creek), and T'it'q'et (Lillooet) are communities that surround the lake. Surrounded by mountainous terrain, the lake is flanked at mid-slope by glacial and colluvial sediments deposited during the last glacial and deglacial periods (Clague, 1989; Jakob, 2018). The bedrock consists mainly of mafic to ultramafic volcanic rocks with minor carbonate and argillite from the Carboniferous to Middle Jurassic periods (Journeay and Monger, 1994). As part of the Public Safety Geoscience Program at the Geological Survey of Canada (Natural Resources Canada), our goal is to provide baseline geoscience information to nearby communities, stakeholders and decision-makers. Our objective was to see what kind of sediments were deposited and specifically if we could identify underwater landslide deposits. Thus, we surveyed the lake using a Pinger SBP sub bottom profiler made by Knudsen Engineering Ltd., with dual 3.5 / 200 kHz transducers mounted to a small boat (see photo). This instrument transmits sound energy down through the water column that reflects off the lake bottom surface and underlying sediment layers. At the lake surface, the reflected sound energy is received by the profiler, recorded on a laptop computer, and integrated with GPS data. These data are processed to generate a two-dimensional image (or profile) showing the character of the lake bottom and underlying sediments along the route that the boat passed over. Our survey in 2022 recorded 98 profiles along Seton Lake. The red transect lines show the locations of the 20 profiles displayed on the poster. The types of sediments observed are mostly fine-grained glaciolacustrine sediments that are horizontally bedded with a subtle transition between glaciolacustrine to lacustrine (e.g., profiles A-A'; C-C'; F-F'; S-S'). Profile S-S' displays this transition zone. The glaciolacustrine sediments probably were deposited as the Cordilleran Ice Sheet retreated from the local area (~13,000-11,000 years ago; Clague, 2017) and the lacustrine sediments, after the ice receded to present-day conditions. Some of the parallel reflections are interrupted, suggesting abrupt sedimentation by deposits that are not horizontally bedded; these are interpreted as landslide deposits (see pink or blue deposits on profiles). The deposits that show disturbance in the sedimentation found within the horizontal beds are thought to be older landslides (e.g., blue arrows/deposits in profiles C-C'; E-E'; F-F'; G-G'; I-I'; J-J'; K-K'; N-N'; P-P'; Q-Q'; R-R'; T-T'; U-U'), but the ones that are found on top of the horizontally laminated sediments (red arrows/pink deposits), and close to the lake wall, are interpreted to be younger (e.g., profiles B-B'; C-C'; H-H'; K-K'; M-M'; O-O'; P-P'; Q-Q'). At the fan delta just west of Seton dam, where there was no acoustic signal penetration, it is interpreted that the delta failed and brought down coarser deposits at the bottom of the lake (e.g., profiles H-H'; M-M'; and perhaps K-K'). However, these could be glacial deposits, bedrock, or other coarser deposits. Some of the deposits that reflect poor penetration of the acoustic signal, below the glaciolacustrine sediments, could represent glacial deposits, old landslide deposits, or perhaps the presence of gas (orange arrows; e.g, B-B'; D-D'; J-J'; O-O', T-T'). The preliminary results from sub bottom profiling reveal that there are underwater landslides deposits of widely varying ages buried in the bottom of the lake. However, the exact timing of these is not known. Hence our preliminary survey gives an overview of the distribution of landslides where there seems to be a larger number of landslides recorded in the narrower eastern portion of the lake.

Humans have now altered essentially every natural ecosystem in the world, and among the numerous consequences of anthropogenic global change, many of the Earth’s species are currently living under drastically different environmental and ecological conditions. On one hand, many species that once thrived in the wild are now threatened by extinction, while at the same time, species that were historically benign are becoming invasive in different parts of the world. To address this major challenge, it is critical that conservation practitioners understand the multiple short- and long-term climatological, geological, and evolutionary mechanisms that have resulted in the current distribution of species; understanding how these same mechanisms interact is also key in predicting species distributions—and possible extinctions—into the future. Using the Global Biodiversity Information Facility (GBIF), an open-access worldwide database of species occurrences, this research project exercise is designed to guide teams of students through the process of: a) identifying and researching characteristics relevant to understanding species distribution (e.g., age of the group, habitat requirements, dispersal capabilities); b) representing the present and historic species distribution; c) critically assessing the quality and amount of information available; d) using that information to understand species history and potential future challenges the species may either face or impose on the ecosystems; and e) sharing the results with peers and learning from that experience.

Background Lung cancer is the number one cause of cancer death worldwide.(1) It is the fifth most commonly diagnosed cancer in Australia (12,741 cases diagnosed in 2018) and the leading cause of cancer death.(2) The number of years of potential life lost to lung cancer in Australia is estimated to be 58,450, similar to that of colorectal and breast cancer combined.(3) While tobacco control strategies are most effective for disease prevention in the general population, early detection via low dose computed tomography (LDCT) screening in high-risk populations is a viable option for detecting asymptomatic disease in current (13%) and former (24%) Australian smokers.(4) The purpose of this Evidence Check review is to identify and analyse existing and emerging evidence for LDCT lung cancer screening in high-risk individuals to guide future program and policy planning. Evidence Check questions This review aimed to address the following questions: 1. What is the evidence for the effectiveness of lung cancer screening for higher-risk individuals? 2. What is the evidence of potential harms from lung cancer screening for higher-risk individuals? 3. What are the main components of recent major lung cancer screening programs or trials? 4. What is the cost-effectiveness of lung cancer screening programs (include studies of cost–utility)? Summary of methods The authors searched the peer-reviewed literature across three databases (MEDLINE, PsycINFO and Embase) for existing systematic reviews and original studies published between 1 January 2009 and 8 August 2019. Fifteen systematic reviews (of which 8 were contemporary) and 64 original publications met the inclusion criteria set across the four questions. Key findings Question 1: What is the evidence for the effectiveness of lung cancer screening for higher-risk individuals? There is sufficient evidence from systematic reviews and meta-analyses of combined (pooled) data from screening trials (of high-risk individuals) to indicate that LDCT examination is clinically effective in reducing lung cancer mortality. In 2011, the landmark National Lung Cancer Screening Trial (NLST, a large-scale randomised controlled trial [RCT] conducted in the US) reported a 20% (95% CI 6.8% – 26.7%; P=0.004) relative reduction in mortality among long-term heavy smokers over three rounds of annual screening. High-risk eligibility criteria was defined as people aged 55–74 years with a smoking history of ≥30 pack-years (years in which a smoker has consumed 20-plus cigarettes each day) and, for former smokers, ≥30 pack-years and have quit within the past 15 years.(5) All-cause mortality was reduced by 6.7% (95% CI, 1.2% – 13.6%; P=0.02). Initial data from the second landmark RCT, the NEderlands-Leuvens Longkanker Screenings ONderzoek (known as the NELSON trial), have found an even greater reduction of 26% (95% CI, 9% – 41%) in lung cancer mortality, with full trial results yet to be published.(6, 7) Pooled analyses, including several smaller-scale European LDCT screening trials insufficiently powered in their own right, collectively demonstrate a statistically significant reduction in lung cancer mortality (RR 0.82, 95% CI 0.73–0.91).(8) Despite the reduction in all-cause mortality found in the NLST, pooled analyses of seven trials found no statistically significant difference in all-cause mortality (RR 0.95, 95% CI 0.90–1.00).(8) However, cancer-specific mortality is currently the most relevant outcome in cancer screening trials. These seven trials demonstrated a significantly greater proportion of early stage cancers in LDCT groups compared with controls (RR 2.08, 95% CI 1.43–3.03). Thus, when considering results across mortality outcomes and early stage cancers diagnosed, LDCT screening is considered to be clinically effective. Question 2: What is the evidence of potential harms from lung cancer screening for higher-risk individuals? The harms of LDCT lung cancer screening include false positive tests and the consequences of unnecessary invasive follow-up procedures for conditions that are eventually diagnosed as benign. While LDCT screening leads to an increased frequency of invasive procedures, it does not result in greater mortality soon after an invasive procedure (in trial settings when compared with the control arm).(8) Overdiagnosis, exposure to radiation, psychological distress and an impact on quality of life are other known harms. Systematic review evidence indicates the benefits of LDCT screening are likely to outweigh the harms. The potential harms are likely to be reduced as refinements are made to LDCT screening protocols through: i) the application of risk predication models (e.g. the PLCOm2012), which enable a more accurate selection of the high-risk population through the use of specific criteria (beyond age and smoking history); ii) the use of nodule management algorithms (e.g. Lung-RADS, PanCan), which assist in the diagnostic evaluation of screen-detected nodules and cancers (e.g. more precise volumetric assessment of nodules); and, iii) more judicious selection of patients for invasive procedures. Recent evidence suggests a positive LDCT result may transiently increase psychological distress but does not have long-term adverse effects on psychological distress or health-related quality of life (HRQoL). With regards to smoking cessation, there is no evidence to suggest screening participation invokes a false sense of assurance in smokers, nor a reduction in motivation to quit. The NELSON and Danish trials found no difference in smoking cessation rates between LDCT screening and control groups. Higher net cessation rates, compared with general population, suggest those who participate in screening trials may already be motivated to quit. Question 3: What are the main components of recent major lung cancer screening programs or trials? There are no systematic reviews that capture the main components of recent major lung cancer screening trials and programs. We extracted evidence from original studies and clinical guidance documents and organised this into key groups to form a concise set of components for potential implementation of a national lung cancer screening program in Australia: 1. Identifying the high-risk population: recruitment, eligibility, selection and referral 2. Educating the public, people at high risk and healthcare providers; this includes creating awareness of lung cancer, the benefits and harms of LDCT screening, and shared decision-making 3. Components necessary for health services to deliver a screening program: a. Planning phase: e.g. human resources to coordinate the program, electronic data systems that integrate medical records information and link to an established national registry b. Implementation phase: e.g. human and technological resources required to conduct LDCT examinations, interpretation of reports and communication of results to participants c. Monitoring and evaluation phase: e.g. monitoring outcomes across patients, radiological reporting, compliance with established standards and a quality assurance program 4. Data reporting and research, e.g. audit and feedback to multidisciplinary teams, reporting outcomes to enhance international research into LDCT screening 5. Incorporation of smoking cessation interventions, e.g. specific programs designed for LDCT screening or referral to existing community or hospital-based services that deliver cessation interventions. Most original studies are single-institution evaluations that contain descriptive data about the processes required to establish and implement a high-risk population-based screening program. Across all studies there is a consistent message as to the challenges and complexities of establishing LDCT screening programs to attract people at high risk who will receive the greatest benefits from participation. With regards to smoking cessation, evidence from one systematic review indicates the optimal strategy for incorporating smoking cessation interventions into a LDCT screening program is unclear. There is widespread agreement that LDCT screening attendance presents a ‘teachable moment’ for cessation advice, especially among those people who receive a positive scan result. Smoking cessation is an area of significant research investment; for instance, eight US-based clinical trials are now underway that aim to address how best to design and deliver cessation programs within large-scale LDCT screening programs.(9) Question 4: What is the cost-effectiveness of lung cancer screening programs (include studies of cost–utility)? Assessing the value or cost-effectiveness of LDCT screening involves a complex interplay of factors including data on effectiveness and costs, and institutional context. A key input is data about the effectiveness of potential and current screening programs with respect to case detection, and the likely outcomes of treating those cases sooner (in the presence of LDCT screening) as opposed to later (in the absence of LDCT screening). Evidence about the cost-effectiveness of LDCT screening programs has been summarised in two systematic reviews. We identified a further 13 studies—five modelling studies, one discrete choice experiment and seven articles—that used a variety of methods to assess cost-effectiveness. Three modelling studies indicated LDCT screening was cost-effective in the settings of the US and Europe. Two studies—one from Australia and one from New Zealand—reported LDCT screening would not be cost-effective using NLST-like protocols. We anticipate that, following the full publication of the NELSON trial, cost-effectiveness studies will likely be updated with new data that reduce uncertainty about factors that influence modelling outcomes, including the findings of indeterminate nodules. Gaps in the evidence There is a large and accessible body of evidence as to the effectiveness (Q1) and harms (Q2) of LDCT screening for lung cancer. Nevertheless, there are significant gaps in the evidence about the program components that are required to implement an effective LDCT screening program (Q3). Questions about LDCT screening acceptability and feasibility were not explicitly included in the scope. However, as the evidence is based primarily on US programs and UK pilot studies, the relevance to the local setting requires careful consideration. The Queensland Lung Cancer Screening Study provides feasibility data about clinical aspects of LDCT screening but little about program design. The International Lung Screening Trial is still in the recruitment phase and findings are not yet available for inclusion in this Evidence Check. The Australian Population Based Screening Framework was developed to “inform decision-makers on the key issues to be considered when assessing potential screening programs in Australia”.(10) As the Framework is specific to population-based, rather than high-risk, screening programs, there is a lack of clarity about transferability of criteria. However, the Framework criteria do stipulate that a screening program must be acceptable to “important subgroups such as target participants who are from culturally and linguistically diverse backgrounds, Aboriginal and Torres Strait Islander people, people from disadvantaged groups and people with a disability”.(10) An extensive search of the literature highlighted that there is very little information about the acceptability of LDCT screening to these population groups in Australia. Yet they are part of the high-risk population.(10) There are also considerable gaps in the evidence about the cost-effectiveness of LDCT screening in different settings, including Australia. The evidence base in this area is rapidly evolving and is likely to include new data from the NELSON trial and incorporate data about the costs of targeted- and immuno-therapies as these treatments become more widely available in Australia.
