Enbridge Pipelines Inc. owns and operates the world’s longest hydrocarbon transmission system, which traverses across the varying geophysical landforms of Canada and the United States. These pipelines range in diameter from 12” to 48” and were constructed between 1950 and 2003. The wide range of pipe sizes, practices used for construction, and landforms traversed result in a very challenging Dent Management Program. Standards such as CSA Z662-99, ASME B31.4, and B31.8 provide a criterion for the selection of dents that require repair. Experience has shown that these standards do not identify all dents that have a possibility of failure due to leak or rupture. Enbridge initiated a project to study dents with BMT Fleet Technology of Kanata Ontario, this study determined that the dent geometry in addition to the depth to pipe diameter ratio affects the propensity that a dent will fail. Recent research and development by a group sponsored project lead by BMT Fleet technology on dent characterization has combined the pipeline’s cyclic pressure history with the shape of the dent to predict a time to failure. Enbridge combines these tools along with new insights from field excavations into its Dent Management Program. The Dent Management Program includes a series of prioritization’s to determine which sections of pipelines require detailed dent analysis. Typical prioritization criteria are rocky terrain, larger occurrence of third party damage, and history of numerous dents or failures. The detailed analysis utilizes the BMT Fleet “Dent Characterization Criteria” which was developed using their Finite Element Dent Assessment Model. This model considers the geometry of the dent, pipe material properties and historical pressure data to predict a time to failure for each dent. This time to failure prediction requires some additional engineering analysis depending on how close the parameters of the actual pipe are to what was validated with the model. This engineering analysis will determine which dents are selected for excavation and examination. This model has provided Enbridge with a tool to better manage its dent program, and this will be proposed as an option to improve the existing standards.

To investigate the recent 150% increase in the reported incidence of ventricular septal defects (VSDs) in the United States, the epidemiology of ventricular septal defects was examined. The apparent incidence of VSDs is highly dependent on case finding methods, and more complete diagnosis and reporting probably account for the increase in reported incidence. Variations in case ascertainment also account for the small differences in incidence in studies from different places. The several known risk factors for VSD, including a family history of congenital heart disease and exposure to certain drugs, infectious agents, and maternal metabolic disturbances, explain few cases. Incidence rates are similar in different races and seasons and are unrelated to maternal age, birth order, sex, and socioeconomic status. VSDs occur naturally in a wide range of mammals and in birds, which also have four-chambered hearts. Despite identical genes and similar prenatal environments, the concordance rate in identical twins is only about 10%. The consistency of incidence among individuals with widely differing genes and environments and the frequency of discordance in identical twins suggest that VSDs often occur as random errors in development, at a frequency largely determined by the complexity of normal cardiac morphogenesis. This hypothesis has two major implications: many VSDs are not preventable and parents need not feel responsible for VSDs in their children.

M. Fabius Quintilianus was a prominent orator, declaimer, and teacher of eloquence in the first century ce. After his retirement he wrote the Institutio oratoria, a unique treatise in Antiquity because it is a handbook of rhetoric and an educational treatise in one. Quintilian’s fame and influence are not only based on the Institutio, but also on the two collections of Declamations which were attributed to him in late Antiquity. The Oxford Handbook of Quintilian aims to present Quintilian’s Institutio as a key treatise in the history of Graeco-Roman rhetoric and its influence on the theory and practice of rhetoric and education, from late Antiquity until the present day. It contains chapters on Quintilian’s educational programme, his concepts and classifications of rhetoric, his discussion of the five canons of rhetoric, his style, his views on literary criticism, declamation, and the relationship between rhetoric and law, and the importance of the visual and performing arts in his work. His huge legacy is presented in successive chapters devoted to Quintilian in late Antiquity, the Middle Ages, the Italian Renaissance, Northern Europe during the Renaissance, Europe from the Eighteenth to the Twentieth Century, and the United States of America. There are also chapters devoted to the biographical tradition, the history of printed editions, and modern assessments of Quintilian. The twenty-one authors of the chapters represent a wide range of expertise and scholarly traditions and thus offer a unique mixture of current approaches to Quintilian from a multidisciplinary perspective.

The article reviews research on Chinese Eastern Railway in China. The research on Chinese Eastern Railway in China began in the early 20th century, has a history of more than 100 years. The existing research results mainly focus on the construction of Chinese Eastern Railway and Tsarist Russia's expansion policy, negotiation between China and Russia (Soviet Union) on the railway issue, the contradictions and struggles of Japan and the United States around the railway problem and so on. These documents cover a wide range of issues which almost involve the political, diplomacy, economy and trade, culture and other fields of international relations in the Far East from the end of the 19th century to the beginning of 20th century, provide a broad vision for the study of Chinese Eastern Railway. But there are problems in the research. Although there are many works on Chinese Eastern Railway, but most discussions are limited to a certain stage, there are few works on the whole history of Chinese Eastern Railway. Not only should we pay attention to the study of the early 20th century in other words the period of the Qing Empire, moreover, we should strengthen the research in the period of the Republic of China and the new China period, this is of great significance to the study of the whole history of Sino — Soviet relations. In addition due to specific historical conditions, part of the Russian data of Chinese Eastern Railway in China was lost, in addition, there is no detailed and authoritative reference book for Russian archives of Chinese Eastern Railway, this situation makes the cited materials in Chinese works appear too old the materials cited in the book seem too old.

Diatraea saccharalis F is considered the most important pest of sugarcane in the United States. This article focuses on the history of pest management as it relates to the control of this stem borer in Louisiana sugarcane, and how control practices have become more in tune with integrated pest management paradigms. Various pest management strategies are employed against D. saccharalis and the interactions between each of these provide farmers with the tools needed to curb damaging infestations. However, the invasion of the Mexican rice borer, Eoreuma loftini (Dyar), and other confounding environmental factors have presented farmers, consultants, and researchers with new pest management challenges. We address these challenges and provide an overview of ongoing developments, particularly in the Louisiana sugarcane pest management program.

For several years now, a group of prominent religious liberty scholars in the United States have been defending what they call a “live-and-let-live” approach to accommodating religious dissent in the era of marriage equality. The proposed approach calls on the state to avoid taking sides on contested moral issues when individuals of faith claim that their religious beliefs require them to refrain from facilitating marriages by same-sex couples. The objective, it is argued, is to adopt policies that allow both sides to live according to their values. This article critiques the “live-and-let-live” solution to religious exemptions from LGBT (lesbian, gay, bisexual, and transgender) equality measures by focusing on questions of harms. It argues that the proposed approach calls for a weighing of harms that is largely unprecedented in the history of American antidiscrimination law and problematic in its own right. The article also explains that the approach is premised on questionable assumptions and predictions about the absence of any meaningful harm to LGBT individuals when business owners provide goods and services to the general public, but refuse to do so for same-sex couples on religious grounds.

The mass media tend to shape the values and opinions of their audience as well as reflect the culture in which they exist. The comics have long been an integral part of the media, appealing to a wide range of age and social class. As such, they could have considerable effect on attitudes and behaviours regarding alcohol consumption. In this paper, we examine the comic strips appearing in the daily newspapers before, during and up to the end of the Prohibition era in the United States, to see how alcohol was portrayed during this period when its manufacture and sale were prohibited.

Risk management of pipelines is a complex challenge due to the dynamic environment of the real world coupled with a wide range of system types installed over many decades. Various methods of risk assessment are currently being used in industry, many of which utilize relative scoring. These assessments are often not designed for the new integrity management program (IMP) requirements and are under direct challenge by regulators. SemGroup had historically used relative risk assessment methodologies to help support risk management decision-making. While the formality offered by these early methods provided benefits, it was recognized that, in order to more effectively manage risk and better meet the United States IMP objectives, a more effective risk assessment would be needed. A rapid and inexpensive migration into a better risk assessment platform was sought. The platform needed to be applicable not only to pipeline miles, but also to station facilities and all related components. The risk results had to be readily understandable and scalable, capturing risks from ‘trap to trap’ in addition to risks accompanying each segment. The solution appeared in the form a quantitative risk assessment that was ‘physics based’ rather than the classical statistics based QRA. This paper will outline the steps involved in this transition process and show how quantitative risk assessment may be efficiently implemented to better guide integrity decision-making, illustrated with a case study from SemGroup.

Collier County, Florida (“County”) is in the midst of developing an integrated waste management program. Unlike many counties, Collier County owns a landfill with sufficient long-term landfill capacity to last another 15 years. However, due to the Board of County Commissioner’s (“Board”) desire to have a 50-year solution for solid waste, the County has set upon a course to divert waste from the landfill to the maximum extent possible. In doing so, the County solicited long-term waste management solutions from private companies capable of processing the majority of the municipal solid waste generated in the County. Over the past two years, the County has considered several of these alternatives ranging from MSW composting to mass-burn waste-to-energy; however, based on an evaluation of a wide range of impacts, gasification was selected as the preferred alternative. With this focus, the County issued a Request for Proposal (“RFP”) in November 2001 for a design, build, own, operate, and finance gasification project. The County received three proposals in April 2002 in response to the RFP. To date, the County has completed the proposal evaluation process and has ranked the top two responsive firms: Interstate Waste Technologies (“IWT”) and Brightstar Environmental (Florida), LLC (“Brightstar”) based on experience, technical approach, business arrangement, and cost. If implemented, this project will be the only commercial gasification project operating in the United States. This paper will provide insight into various stages of the project, from development through to the current status of the project, as well as the strategic policy, financial, and technical considerations that make this opportunity a good fit for the County. An emphasis will also be placed on comparing and contrasting the benefits and drawbacks of each technology, such as processing methodology, cost, redundancy, and scalability.

Daunting Challenge

Over the more than twenty years since the publication of two profoundly influential collections—Errol Hill's two-volume anthology of critical essays The Theatre of Black Americans (1980) and James V. Hatch's first edition of the play anthology Black Theatre USA (1974)—there has been considerable activity in African American theatre scholarship. Yet even as scholars have produced new collections of historical and critical essays that cover a wide range of African American theatre history, book-length studies that document particular moments in the historical continuum such as the Harlem Renaissance, and Samuel Hay's broader study African American Theatre: An Historical and Critical Analysis (1994), no one until now has written a comprehensive study of African American theatre history. Into this void have stepped two of the aforementioned distinguished scholars of African American theatre, Errol G. Hill and James V. Hatch. To be certain, writing a comprehensive history of African American theatre poses a daunting challenge for anyone hearty enough to undertake it. Where to begin? What to include and exclude? With their study, A History of African American Theatre, Hill and Hatch show themselves indeed worthy of the challenge. They explore the evolution of African American theatre across time and space, documenting the particular efforts of artists, writers, scholars, and practitioners, from inside as well as outside the United States, that have had an impact on our understanding of African American theatre. The authors make clear that the definition of African American theatre from the beginning has been in constant flux and that it has been affected by the changing social times in American as much as it has influenced those times.

AbstractHistorians of religion have devoted little attention to shrines in the United States, and the limited scholarship that is available has overlooked Protestants. Protestants, most interpreters have assumed, do not have shrines or make pilgrimages. In this essay I define and classify shrines, surveying a wide range of sacred sites in the United States. Then I challenge the assumptions about Protestants and pilgrimage. Focusing on the United Methodists, I argue that while the spiritual descendants of John Wesley do not consecrate all types of sacred sites or endorse all pilgrimage practices, commemorative shrines play a role in American Methodist piety. If I am right, Protestants, and American Methodists in particular, are less anomalous in the history of religion than most scholars have assumed.
