Abstract (sommario):
The objective of this paper is to outline how stable isotope techniques can contribute to the elucidation of the sources and the fate of riverine nitrate and sulphate in watershed studies. The example used is the Oldman River Basin (OMRB), located in southern Alberta (Canada). Increasing sulphate concentrations and decreasing δ34S values along the flowpath of the Oldman River indicate that oxidation of pyrite in tills is a major source of riverine sulphate in the agriculturally used portion of the OMRB. Chemical and isotopic data showed that manure-derived nitrogen contributes significantly to the increase in nitrate concentrations in the Oldman River and its tributaries draining agricultural land. It is suggested that hydrological conditions control agricultural return flows to the surface water bodies in southern Alberta and impart significant seasonal variations on concentrations and isotopic compositions of riverine nitrate. Combining isotopic, chemical, and hydrometric data permitted us to estimate the relative contribution of major sources to the total solute fluxes. Hence, we submit that isotopic measurements can make an important contribution to the identification of nutrient and pollutant sources and to river basin management.

Abstract (sommario):
Long-term trends in alpine and prairie snow pack accumulation and melt are affecting streamflow within the Oldman River Basin in southern Alberta, Canada. Unchecked rural and urban development also has contributed to changes in water quality, including enhanced microbial populations and increased water-borne pathogen occurrence. In this study we look at changing environment within the Oldman River Basin and its impact on water quality and quantity. The cumulative effects include a decline in net water supplies, and declining quality resulting in increased risk of disease. Our data indicates that decreases in the rate of flow of water can result in sedimentation of bacterial contaminants within the water column. Water for ecosystems, urban consumption, recreation and distribution through irrigation is often drawn from water-holding facilities such as dams and weirs, and concern must be expressed over the potential for contaminate build-up and disproportionate potential of these structures to pose a risk to human and animal health. With disruption of natural flow rates for water resulting from environmental change such as global warming and/or human intervention, increased attention needs to be paid to use of best management practices to protect source water supplies.

Abstract (sommario):
The aging of the American workforce will lead to shortages in skilled workers throughout the country in the near future. Minorities are already underrepresented in the transportation industry, and without immediate intervention the conditions will not improve. To address the anticipated shortfall in skilled minority labor, FHWA, in coordination with the South Carolina Department of Transportation and South Carolina State University, developed the Summer Transportation Institute. In the Texas Gulf Coast region, the Center for Transportation Training and Research at Texas Southern University has introduced the transportation industry to minority high school students while emphasizing the importance of science, technology, engineering, and mathematics skills in tomorrow's workplace through summer education programs for nearly 10 years. A study examines the core curriculum of those programs and discusses their potential applicability in other regions of Texas.

Abstract (sommario):
This paper highlights the environmental impacts of implementing beneficial management practices to address cattle bedding and direct access to the creek in a study watershed in southern Alberta, Canada. Approximately 35 cow–calf pairs grazed 194 ha of grass forage and had direct access to the creek in the spring and summer. During winter, the cattle were fed adjacent to the creek at an old bedding site. The practice changes included off-stream watering, bedding site relocation and fencing for rotational grazing. The cost was $15,225 and 60 h of labour. Four years of data were used in a before-and-after experimental design to evaluate the practice changes. After two years of post-implementation monitoring, riparian assessments showed an increase in plant diversity, but no change in the percent cover of the riparian species Salix exigua and Juncus balitus and a decrease in Carex sp. (P < 0.05). Water quality monitoring showed a decrease in the difference between upstream and downstream concentrations of total phosphorus, total dissolved phosphorus, total nitrogen, organic nitrogen and Escherichia coli (P < 0.10). These results showed that improved environmental changes in riparian and water quality can be measured following the implementation of beneficial management practices for cattle bedding and grazing.

Abstract (sommario):
The Hotchkiss River Mixedwood Timber Harvesting Study is a cooperative project involving Canadian Forest Service, Daishowa-Marubeni International Ltd., Manning Diversified Forest Products Ltd., the Forest Engineering Research Institute of Canada and Alberta Land and Forest Service aimed at developing new approaches to natural regeneration and harvesting systems for western Canada's boreal mixedwood forests, at a site near the Hotchkiss River in northwestern Alberta. The study used conventional harvesting equipment to test eleven harvesting and silvicultural systems designed to protect and minimize wind damage to immature white spruce residuals and encourage vigorous hardwood regeneration following harvest of the aspen overstory. Research areas include wind damage, wind firmness and growth response of the immature white spruce, effects of harvesting disturbance and timing on soil properties, conifer and hardwood regeneration after harvest, efficiency of equipment and harvesting costs, modelling of wind flow and long-term growth and yield. Already in its sixth year, the project has a planned 20year series of harvests and surveys. Technology transfer is an important component of this study for delivery and promotion of research results on behalf of the proponents and all related research collaborators. Products include demonstration maps and field guides, self-guided tour trails with interpretive signage and field tours (including active operations) as required. Hotchkiss River has also been designated a Forest Ecosystem Research Network (FERN) site. Key words: silviculture systems, white spruce, Picea glauca, aspen, Populus tremuloides, understory protection, harvesting, Alberta, boreal mixedwoods, technology transfer

Abstract (sommario):
We summarize the feasibility of using geothermal energy from the Western Canada Sedimentary Basin (WCSB) to support communities with populations >3000 people, including those in northeastern British Columbia, southwestern part of Northwest Territories (NWT), southern Saskatchewan, and southeastern Manitoba, along with previously studied communities in Alberta. The geothermal energy potential of the WCSB is largely determined by the basin’s geometry; the sediments start at 0 m thickness adjacent to the Canadian shield in the east and thicken to >6 km to the west, and over 3 km in the Williston sub-basin to the south. Direct heat use is most promising in the western and southern parts of the WCSB where sediment thickness exceeds 2–3 km. Geothermal potential is also dependent on the local geothermal gradient. Aquifers suitable for heating systems occur in western-northwestern Alberta, northeastern British Columbia, and southwestern Saskatchewan. Electrical power production is limited to the deepest parts of the WCSB, where aquifers >120 °C and fluid production rates >80 kg/s occur (southwestern Northwest Territories, northwestern Alberta, northeastern British Columbia, and southeastern Saskatchewan. For the western regions with the thickest sediments, the foreland basin east of the Rocky Mountains, estimates indicate that geothermal power up to 2 MWel. (electrical), and up to 10 times higher for heating in MWth. (thermal), are possible.

Abstract (sommario):
Work-integrated learning (WIL) continues to be an essential topic of conversation among governments, educators, employers, and students. By various names and definitions, WIL attempts to inject the realism of workplace employment tasks into the post-secondary learning environment. The COVID-19 pandemic has forced stakeholders to innovate in the WIL space often using the advances in information and communications technologies (ICT) to build further bridges between learners and real work experiences. The chapter provides an overview of WIL followed by three specifics cases from marketing faculty at the Southern Alberta Institute of Technology (SAIT). In each of the three cases, faculty used different ICT to provide engaging learning environments linking business, industry, consumers, and the learners.

Abstract (sommario):
Abstract The ubiquity of complicated and extended-reach horizontal wellbores with tighter windows has spurred the copious use of the rotary steerable system (RSS) in drilling operations. This magnetic-powered RSS technology, initially designed for the offshore drilling market, has proven to be an effective solution to the increasingly complex challenges in the land-based market. Although durable, as with other mechanical devices, equipment failure and malfunction may occur during drilling operations. The impairments of these expensive high-end systems while drilling often lead to costly trips and NPTs, which can be avoided with regular maintenance practices. Apart from these regular maintenance practices, it is also paramount to devise proactive techniques while drilling that will enhance the life cycle of these systems and prevent rampant and uneconomical trips. This paper presents a proven methodology that was used to eliminate the rampant RSS tool failures encountered on multiple rigs in Southern Alberta, Canada. While RSS tool failures have traditionally been attributed to the barite and mud system, scientific root cause analysis showed that ferromagnetic iron metal generated from different sources while drilling induced these failures. Ferromagnetic Iron has the potential to cause interference with downhole magnetic tools, causing them to fail and have solids entrapped in them. An ingenious operational procedure was devised and implemented using strategically generated magnetic fields in the mud circulation system at different locations. These magnetic fields strip the mud system of ferromagnetic materials to prevent damage to RSS tools. This procedure was also backed up with a novel testing technique that identifies and quantifies the presence of ferromagnetic materials in the mud system, which can be tracked on the daily drilling report or posted on a digital database. The test results help engineers detect the buildup of ferromagnetic iron in the mud system (indicating the strength of the magnetic fields) and the appropriate mitigation strategy to employ, which may include strengthening the magnetic fields and using centrifuges depending on the scenario. This successful approach eliminated RSS tool failures on multiple rigs and reduced Tool-Failure NPTs drastically by over 47% on average. This paper breaks down, showcases, and elucidates a practical engineering solution to a prevalent drilling problem, with easy-to-follow steps that can be replicated by mud engineers and technicians anywhere in the world.

Abstract (sommario):
The implementation, support, and ultimate success of digitally-informed innovations to teaching and learning practices requires focused intentionality whose approach is grounded in academic rigour, practical experience and organizational maturity. The success of technology-supported innovation in higher-education teaching and learning practices, driven by external factors like COVID and the resultant economic challenges, will be explored in relation to teaching faculty and administrative leaders developing and maintaining positive motivation towards change including addressing major organizational challenges. // Innovation, Change and Transformation // As Senior Instructor Emeritus, Ron Murch has more than 45 years of experience with the University of Calgary’s Haskayne School of Business. Ron maintains that digital transformation requires faculty members to adopt the requisite innovations in practice and technologies as imagined by the Technology Acceptance Model and expanded upon by two key principles - each new practice or technology must have recognizable and positive value for the individual who is changing; and it cannot be too difficult for the adopter to work with. // Guiding Principles // Dr. Peter Chatterton is a Chartered Physicist and digital innovator. He worked in roles such as critical friend, evaluator and change management consultant with the UK Government’s multi-million £s HEI digital innovation and transformation programmes during 2000-2020. From this experience, Peter asserts that HEIs can be both creative and effective at digital innovation. However, scaling-up and embedding such innovations to build long-term resilience and effect digital transformation across the institution invariably faces numerous challenges. These are explored through the lens of seven key guiding principles for digitally transforming learning programmes for open and flexible learning. // Commitment and Motivation // Michael Barr is Chief Information Officer at the Southern Alberta Institute of Technology in Calgary, Alberta, and a doctoral student in higher education management at the University of Bath, UK. Building on a theory of behavior in organizations, Michael explores the motivation process and its impact on the construction of strategic plans and the organization’s ability to deliver successful outcomes. He draws upon 28 years’ of IT practitioner experience to ground his scholarly work with practical advice and considerations for undertaking digital transformation of teaching and learning practices.

Abstract (sommario):
This narrative describes an initiative of the National Service Scheme team at Andhra Loyola Institute of Engineering and Technology. It highlights initiatives to address the situation of migrant workers during the pandemic lockdown in the southern state of Andhra Pradesh in India. In the Krishna District of Andhra Pradesh, migrant laborers were forced to walk home, sometimes hundreds, even thousands of kilometers, to reunite with their families. It was hard to ignore these images, especially those who carried the elderly on their shoulders, and small children slumped over rolling suitcases. Most used any means of transport they found, even bicycles. Some succumbed to accidents and exposure to heat. In the midst of the lockdown, the NSS team quickly came together and planned an outreach/relief camp for migrants in Krishna District. It was chosen since many villagers were migrants and the lockdown had affected in multiple ways. The relief camp took place in the month of April, a time when temperatures soar in southern India. The students and the faculty members joined hands to reach out to the Migrants in the most despairing moments. The students commented that they saw their education from a different perspective, one that integrated curriculum and good citizenship for marginalized persons. One of the ways of infusing relevance into education is to embed it within meaningful service learning. This paper is an attempt to exhibit the Initiative and Responses to the Migrant workers during the Lockdown.

Abstract (sommario):
The Power Systems Development Facility (PSDF) is an engineering scale demonstration of advanced coal-fired power systems and high-temperature, high-pressure gas filtration systems. The PSDF was designed at sufficient scale so that advanced power systems and components can be tested in an integrated fashion to provide data for commercial scale-up. The PSDF is funded by the U.S. Department of Energy, the Electric Power Research Institute, Southern Company Services, Kellogg Brown & Root, Inc. (KBR), Siemens-Westinghouse, and Peabody Energy. Gasification at the PSDF is based on KBR’s Transport Gasifier, which is an advanced circulating fluidized-bed gasifier. Hot gas filtration is a critical process in the gasification system to clean up the particulate matter before the synthesis gas (syngas) is fed to the turbine. A Siemens-Westinghouse particulate control device (PCD) is used for syngas cleanup. The PCD contains 91 candle-style filter elements. More than twenty types of filter elements, categorized as monolithic ceramic, composite ceramic, sintered-metal powder, and sintered-metal fiber, have been tested in the gasification environment at the PSDF. Up to January 2005, the longest exposure time for individual filters has been 5783 hours. The particulate loading in the clean syngas during most stable operating periods has been demonstrated to be consistently below 0.1 ppmw, which is the lower detection limit of Southern Research Institute’s sampling system. Safeguard devices (failsafes) have also been tested and developed at the PSDF. Failsafes are used to block the particulate leaking through the PCD in the case of filter element failure to eliminate damage to the turbine. Demonstration of reliable failsafes is a critical factor to the hot gas filtration technology. Several types of currently available failsafes and PSDF-developed failsafes have been tested in the PCD with gasification ash injection to simulate filter element leakage. A typical failsafe was also tested in a device equipped with a quick-open mechanism to simulate a complete filter failure during a test run operation. The testing showed promising results for certain types of failsafes. Further failsafe testing and better understanding of turbine requirements for particulate loading are needed to evaluate the PCD performance and increase readiness towards commercialization of the technology.

The PSDF was designed at sufficient size so that system components can be evaluated and assessed in an integrated fashion to provide data for commercial scale-up. The PSDF is funded by the U.S. Department of Energy, the Electric Power Research Institute, Southern Company, Siemens Power Generation, Kellogg Brown & Root (KBR), Peabody Energy, Burlington Northern Santa Fe Corporation, and the Lignite Energy Council. Coal gasification at the PSDF is achieved with the KBR Transport Gasifier. Particulate laden gas exiting the gasifier is filtered by a downstream particulate control device (PCD). The PCD is a hot-gas filter that can hold up to 91 filter elements arranged in two tiers, with 36 elements in the top cluster and up to 55 elements in the bottom cluster. More than 30 different types of sintered metal powder, metal fiber, and ceramic filter elements have been tested. As of October 2006, the longest exposure of an individual element was approximately 8550 hours, which was achieved with a Pall iron aluminide sintered metal powder element. The outlet particle loading during normal operation has been reliably maintained within the lower limit of measurement resolution (routinely less than 0.1 ppmw). Downstream of each filter element is a failsafe device to prevent particulate leakage in the event of a filter element failure. The failsafe device is a small filter element or other type of particle collector and serves as a backup to the primary filter element. Demonstration of reliable failsafes is a critical factor in advancing hot gas filtration technology and increasing readiness for commercialization. A failsafe test program was developed at the PSDF to identify failsafe devices that would provide satisfactory protection of a gas turbine from particulate damage. In tests that simulated the failure of a single filter element, both metallic and ceramic failsafe devices were typically able to produce an outlet particle loading below 0.1 ppmw after an initial period of seasoning. From the overall particulate collection efficiency point of view, the failsafes tested showed promising results of protecting a gas turbine from being damaged by particles in the event of a filter failure. This paper focuses on failsafe performance and effectiveness in preventing particulate leaking through the PCD in the event of a filter element failure.

Abstract (sommario):
Abstract Data integration is a foundational element and a regulatory requirement for pipeline operators as part of an Integrity Management (IM) program. Having taken effect in July 2020, the Pipeline Hazardous Materials and Safety Administration’s (PHMSA) new Gas Mega Rule heavily emphasizes the requirement for the validation of data and records. As a result, pipeline operators must face new challenges to ensure they are in continuous regulatory compliance. Data integration plays a major role in supporting pipeline operators and engineering consultants as they adjust to the new requirements set forth in regulations. The Integrity Management (IM) regulations require pipeline operators to include the results of the latest as well as of previous integrity evaluations, including risk assessment information based on integrated data from the entire pipeline. Leveraging this data and the analysis thereof is required when making decisions regarding the course of action to address pipeline threats. The American Petroleum Institute (API) Technical Report (TR) 1178, “Integrity Data Management and Integration,” provides a compendium of systematic methodologies, recommendations and processes to spatially integrate and normalize integrity data to empower pipeline operators to efficiently analyze integrity-related data to support their integrity management decisions and programs. Through the execution of multiple post-ILI service projects, the significance of this TR has been realized as a cornerstone to support pipeline operators in their efforts to meet the requirements of new regulations and achieve compliance. In the present case study, ILI results from various inspections gathered from over 179 post-ILI data integration projects for a mid-size pipeline operator located in the southern United States — totaling over 5,500 mi of pipe segments and ranging in diameter from 10″ to 24″ — were analyzed following the core processes described in API TR 1178. The datasets — ranging from hundreds to hundreds of thousands of integrity data records from different sources including a variety of in-line inspection (ILI) tool technologies and service providers — were interpreted to distinguish pipe features or references from anomalies. Subsequent analyses were applied to the integrated datasets and delivered per the pipeline operator’s specifications. This effort greatly supported a seamless transition to achieve compliance with the new regulations and help to establish reporting requirements for technology and inspection service providers. The operator now has a complete historical ILI database. As it is fully integrated into the GIS system of record, the pipeline operator is able to transition into advanced analytics, helping them to spot trends and make sounder integrity management decisions long-term.
