A methodology for the efficient computer representation of dynamic power systems : application to wind parks

This contribution presents a methodology to efficiently obtain the numerical and computer solution of dynamic power systems with high penetration of wind turbines. Due to the excessive computational load required to solve the abc models that represent the behavior of the wind turbines, a parallel processing scheme is proposed to enhance the solution of the overall system. Case studies are presented which demonstrate the effectiveness and applications of the proposed methodology

Lake Manitoba and its Watershed: Knowledge Gaps & Next Steps

This workshop was the result of many hours of planning and hard work by a committee consisting of Nora Casson, Diane Orihel, Gordon Goldsborough, Scott Forbes, Elise Watchorn, Scott Higgins and Pascal Badiou. The workshop was facilitated by Sheldon McLeod and the report writing was led by Marliese Peterson and Nora Casson. Marliese Peterson also coordinated the note taking during the workshop, and was assisted by Madeline Stanley, Chris Hope, Jill Watling, Alexandra Goodman, and Hailey Robichaud.Lake Manitoba is a large, shallow prairie lake located in central Manitoba. The lake and watershed are subject to numerous environmental pressures including climate change, land use change, and regulation of water levels, particularly during the operation of the Portage Diversion which diverts water from the Assiniboine River into Lake Manitoba. There are substantial gaps in our scientific knowledge about the ecology, limnology, and hydrology of Lake Manitoba, which limit our ability to make informed management decisions. A science workshop was convened at the University of Winnipeg in December 2015 to summarize the state of knowledge around water quality and ecosystem functioning in Lake Manitoba and its watershed, identify key knowledge gaps, and develop ways to address these gaps. The workshop was attended by 34 participants from universities, government agencies, and non-governmental organizations, all of whom had particular expertise in one of four theme areas: Water Levels & Regulation; Watershed Management & Landscape Processes; Water Quality; and Ecology & Wetlands. This report summarizes the findings and recommendations of the workshop, and can be used to help guide research priorities into the future. While specific, detailed recommendations were made in each theme area, two major recommendations emerged across all themes. The first recommendation is the existence of critical data gaps which must be filled before progress can be made on understanding ecosystem functioning. These gaps include physical data (e.g. bathymetric, meteorological and LiDAR data), water quality data (e.g. off-shore water chemistry, tributary nutrient loading), and ecological data (e.g. algal community composition, zooplankton characterization, macroinvertebrates population estimates). Furthermore, we do not understand the extent of spatial and temporal heterogeneity in the Lake Manitoba system. Much of the monitoring that does take place occurs along the edges of the lake during the open water season, resulting in large gaps in our understanding of processes occurring in the middle of the lake or during the winter. Without filling these critical data gaps, our scientific understanding of the system is incomplete and we are limited in our ability to make recommendations to resource managers and stakeholders. The second general recommendation that emerged is the need to coordinate research activities across disciplines and agencies. Lake Manitoba and its watershed are complex ecosystems which are connected to the landscape and other waterbodies, including Lakes Winnipeg and Winnipegosis. To this end, we propose establishing a Manitoba Great Lakes Research Consortium to coordinate and disseminate research across Manitoba’s Great Lakes. Such an organization could also facilitate a repository to make data collected from Lake Manitoba and connected ecosystems accessible to researchers and stakeholders. While there are major gaps in our understanding of ecosystem functions in Lake Manitoba and its watershed, this report provides a way forward. For the gaps that were identified as the most pressing, workshop participants outlined plans of action to address these gaps, including identifying collaborators, potential sources of funding, and timelines to achieve these goals. These next steps will be useful to researchers, government agencies, and non-governmental organizations as they move forward to address the issues facing Lake Manitoba.Environment Canada, University of Winnipeg, University of Manitoba, Manitoba Conservation and Water Stewardship, Ducks Unlimited, International Institute for Sustainable Developmen

Green and Growing: Building A Green And Prosperous Future For Manitoba Families

Green and Growing is a strategic framework that will continue to be developed and expanded as we go forward. Through this strategic framework, we hope to provide Manitobans, and the world, with a better understanding of the Manitoba government’s overall approach to the environment as well as the health and well-being of our province and its families. Our goal is to build a future that promises to be both green and growing for the benefit of all Manitobans

Missing Patients Research Guide

This Burials Research Guide contains directions for finding out more about missing patients at TB sanatoriums and Indian hospitals in Manitoba. Part One of the Guide has three sections. The first section explains how to gather useful details including names, dates and locations that will help in the search. The second section outlines three useful “Research Tips”: all the various names of TB treatment hospitals in Manitoba commonly attended by Indigenous patients; instructions for undertaking database searches using keywords; and techniques for linking information between Indian residential schools and hospitals. The third section is a “Research Case Study” that demonstrates some of the techniques and challenges you may encounter when researching Vital Statistics and Indian Residential School records by looking at the lives of three TB patients, Elie Caribou, Joseph Michel, and Albert Linklater. Part Two of the Guide explains how to research the location of patient burials associated with nine different TB treatment hospitals in Manitoba: Dynevor, Clearwater Lake, Brandon, Ninette, St. Boniface, Fort Churchill Military Hospital, Norway House Indian Hospital, Fisher River Indian Hospital and Pine Falls Indian Hospital at Fort Alexander. At the end of the Guide, in Appendix A, you will find a checklist to help you in your research. In Appendix B, we discuss accessing the records held by The National Centre for Truth and Reconciliation

Nanotechnology – an emerging technology for use in agricultural and food research

Abstract Nanotechnology, the science of building atomic, molecular or macro-molecular sized materials, devices, structures or systems is finding applications in different fields. The technology is presently utilized by the chemical, health care, biotech, and manufacturing industries. In the pharmaceuticals, drugs with nano-sized particles are highly efficient with minimal side effects. Micro-scale mechanical and electro mechanical devices are determined to be highly sensitive, durable, and less expensive. Nanotechnology has potential applications in agricultural and food engineering such as exploring biological life processes, monitoring plant and animal health, analyzing and determining product qualities, developing novel materials from agricultural products, and reducing environmental pollutions. This short article reviews the present applications of nanotechnology in other industries and explores its potential applications in agricultural and food industries

Bridging The Gap Between Higher Education And The Workforce: A Coach Approach To Teaching

Abstract There is debate in the business community around whether new entrants to the labour market are as proficient in essential skills such as communications, collaboration, and critical thinking as were their forbears. At the same time, the demand for executive coaching has increased substantially under both strong and weak economic conditions. Corporations are now using coaching to enhance essential skills within the workplace, which gives rise to questions about college graduates' skills and the positive impact coaching skills could have if embedded within academia. We explore the benefits of using a coach approach in the classroom whereby the instructor engages, enlightens, and empowers students to better prepare graduates for life-long learning and the labour market. The model requires the instructor to embrace authenticity, insight, and innovation by taking a coach approach to teaching with the intent to enhance learning outcomes

Effects of anti-resorptive agents on trabecular bone score (TBS) in older women.

We evaluated the longitudinal effects of anti-resorptive agents (534 treated women vs. 1,150 untreated) on lumbar spine bone mineral density (BMD) and trabecular bone score (TBS). TBS was responsive to treatment in women over age 50. The treatment-related increase in TBS was less than the increase in BMD, which is consistent with bone texture preservation. INTRODUCTION: In addition to inducing an increase in BMD, anti-resorptive agents also help to preserve bone architecture. TBS, a new gray-level texture measurement, correlates with 3D parameters of bone micro-architecture independent of BMD. Our objective was to evaluate the longitudinal effects of anti-resorptive agents on lumbar spine BMD and TBS. METHODS: Women (≥50 years), from the BMD program database for the province of Manitoba, Canada, who had not received any anti-resorptive drug prior to their initial dual X-ray absorptiometry (DXA) exam were divided into two groups: untreated, those without any anti-resorptive drug over the course of follow-up, and treated, those with a non-estrogen anti-resorptive drug (86 % bisphosphonates, 10 % raloxifene, and 4 % calcitonin). Lumbar spine TBS was calculated for each lumbar spine DXA examination. Changes in TBS and BMD between baseline and follow-up (mean follow-up 3.7 years), expressed in percentage per year, were compared between the two groups. RESULTS: A total of 1,150 untreated women and 534 treated women met the inclusion criteria. Only a weak correlation was seen between BMD and TBS in either group. Significant intergroup differences in BMD change and TBS change were observed over the course of follow-up (p < 0.001). Similar mean decreases in BMD and TBS (-0.36 %/year and -0.31 %/year, respectively) were seen for untreated subjects (both p < 0.001). Conversely, treated subjects exhibited a significant mean increase in BMD (+1.86 %/year, p < 0.002) and TBS (+0.20 %/year, p < 0.001). CONCLUSION: TBS is responsive to treatment with non-estrogen anti-resorptive drug therapy in women over age 50. The treatment-related increase in TBS is less than the increase in BMD, which is consistent with bone texture preservation
