The Canadian hydrogen safety program (CHSP) is a project initiative of the Codes and Standards Working Group of the Canadian transportation fuel cell alliance (CTFCA) that represents industry, academia, government, and regulators. The Program rationale, structure and contents contribute to acceptance of the products, services and systems of the Canadian Hydrogen Industry into the Canadian hydrogen stakeholder community. It facilitates trade through fair insurance policies and rates, effective and efficient regulatory approval procedures and accommodation of the interests of the general public. The Program integrates a consistent quantitative risk assessment methodology with experimental (destructive and non-destructive) failure rates and consequence-of-release data for key hydrogen components and systems into risk assessment of commercial application scenarios. Its current and past six projects include Intelligent Virtual Hydrogen Filling Station (IVHFS), Hydrogen clearance distances, comparative quantitative risk comparison of hydrogen and compressed natural gas (CNG) refuelling options; computational fluid dynamics (CFD) modeling validation, calibration and enhancement; enhancement of frequency and probability analysis, and Consequence analysis of key component failures of hydrogen systems; and fuel cell oxidant outlet hydrogen sensor project. The Program projects are tightly linked with the content of the International Energy Agency (IEA) Task 19 Hydrogen Safety. (author)
The National Research Council of Canada is establishing a coordinated national program of fusion research and development that is planned to grow to a total annual operating level of about $20 million in 1985. The long-term objective of the program is to put Canadian industry in a position to manufacture sub-systems and components of fusion power reactors. In the near term the program is designed to establish a minimum base of scientific and technical expertise sufficient to make recognized contributions and thereby gain access to the international effort. The Canadian program must be narrowly focussed on a few specializations where Canada has special indigenous skills or technologies. The programs being funded are the Tokamak de Varennes, the Fusion Fuels Technology Project centered on tritium management, and high-power gas laser technology and associated diagnostic instrumentation
In support of the Treaty on the Non-Proliferation of Nuclear Weapons Canada provides technical support to the International Atomic Energy Agency for the development of safeguards relevant to Canadian designed and built nuclear facilities. Some details of this program are discussed, including the philosophy and development of CANDU safeguards systems; the unique equipment developed for these systems; the provision of technical experts; training programs; liaison with other technical organizations; research and development; implementation of safeguards systems at various nuclear facilities; and the anticipated future direction of the safeguards program
CANDU power reactor fuel has demonstrated an enviable operational record. More than 99.9% of the bundles irradiated have provided defect-free service. Defect excursions are responsible for the majority of reported defects. In some cases research and development effort is necessary to resolve these problems. In addition, development initiatives are also directed at improvements of the current design or reduction of fueling cost. The majority of the funding for this effort has been provided by COG (CANDU Owners' Group) over the past 10 to 15 years. This paper contains an overview of some key fuel technology programs within COG. The CANDU reactor is unique among the world's power reactors in its flexibility and its ability to use a number of different fuel cycles. An active program of analysis and development, to demonstrate the viability of different fuel cycles in CANDU, has been funded by AECL in parallel with the work on the natural uranium cycle. Market forces and advances in technology have obliged us to reassess and refocus some parts of our effort in this area, and significant success has been achieved in integrating all the Canadian efforts in this area. This paper contains a brief summary of some key components of the advanced fuel cycle program. (Author) 4 figs., tab., 18 refs
Canada supports international safeguards as a means by which the proliferation of nuclear weapons can be discouraged. Canada recognizes that,to meet that the IAEA must have effective safeguards techniques and the active cooperation of Member States. Therefore the Canadian Government decided in 1976 to initiate a program in support of IAEA safeguards, known as the Canadian Safeguards Support Program (CSSP). The CSSP is funded and administered by the Atomic Energy Control Board (AECB). The CSSP is a co-ordinated program for the development and the application of safeguards instruments and techniques for nuclear facilities and materials on behalf of the IAEA and also in support of Canada's own national nuclear material safeguards system, implemented by the AECB.

A brief review of the Canadian nuclear power program is presented. Domestically developed CANDU (CANada Deuterium Uranium) reactors account for all of Canada's nuclear electric capacity (5000 MWe in operation and 10,000 MWe under construction or in commissioning) and have also been exported. CANDU reactors are reliable, efficient, and consistently register in the world's top ten in performance. The safety record is excellent. Canada has excess capability in heavy water and uranium production and can easily service export demands. The economic activity generated in the nuclear sector is high and supports a large number of jobs. The growth in nuclear commitments has slowed somewhat as a result of the worldwide recession; however, the nuclear share of expected electricity demand is likely to continue to rise in the next decade. Priorities in the future direction of the program lie in the areas of maintaining high response capability to in-service problems, improving technology, high-level waste management, and advanced fuel cycles.

Defence R&D Canada (DRDC), an agency within the Department of National Defence, has been conducting research and development (R&D) on the detection of landmines for countermine operations and of unexploded ordnance (UXO) for range clearance since 1975. The Canadian Centre for Mine Action Technologies (CCMAT), located at DRDC Suffield, was formed in 1998 to carry out R&D related to humanitarian demining. The lead group responsible for formulating and executing both countermine and humanitarian R&D programs in detection is the Threat Detection Group at DRDC Suffield. This paper describes R&D for both programs under the major headings of remote minefield detection, close-in scanning detection, confirmation detection and teleoperated systems. Among DRDC's achievements in landmine and UXO detection R&D are pioneering work in electromagnetic and magnetic identification and classification; the first military-fielded multisensor, teleoperated vehicle-mounted landmine detection system; pioneering use of confirmation detectors for multisensor landmine detection systems; the first fielded thermal neutron activation landmine confirmation sensor; the first detection of landmines using a real-time hyperspectral imager; electrical impedance imaging detection of landmines and UXO and a unique neutron backscatter landmine imager.

The progressions and selection of design features for the Canadian segment of a mobile satellite (MSAT) communications system are traced. The feasibility study for a satellite-based public and government mobile communications service to underserved areas was carried out between 1980-82. The results covered the market demand, commercial viability, user cost-benefit, and spacecraft concepts. A subsequent 2 yr study was initiated to proceed with project definition. A market of 1.1 million users was identified in all of Canada, with MSAT replacing other systems for 50 percent of the market. Operations would be in the 806-890 MHz range. Traffic will be routed through gateway links functioning in the 8/7 GHz SHF band while the mobile units will be connected through an 821-825 MHz up link and an 866-870 MH downlink. New technologies will be needed for a central control station, the gateway stations, and the base stations for the mobile radio service, the mobile user terminals, and data collection platforms.
The Canadian Nuclear Fuel Waste Management Program involves research into the storage and transportation of used nuclear fuel, immobilization of fuel waste, and deep geological disposal of the immobilized waste. The program is now in the fourth year of a ten-year generic research and development phase. The objective of this phase of the program is to assess the safety and environmental aspects of the deep underground disposal of immobilized fuel waste in plutonic rock. The objectives of the research for each component of the program and the progress made to the end of 1983 are described in this report
The Intern Program was introduced at the Canadian Nuclear Safety Commission, Canada's Nuclear Regulator in response to the current competitive market for engineers and scientists and the CNSC's aging workforce. It is an entry level staff development program designed to recruit and train new engineering and science graduates to eventually regulate Canada's nuclear industry. The program provides meaningful work experience and exposes the interns to the general work activities of the Commission. It also provides them with a broad awareness of the regulatory issues in which the CNSC is involved. The intern program is a two-year program focusing on the operational areas and, more specifically, on the generalist functions of project officers. (author)
An overview is presented of the status of the research and development program, under rsponsibility of the Atomic Energy of Canada Limited (AECL), for assessing the concept of nuclear fuel waste disposal deep in plutonic rock of the Canadian Shield. A passive multi-barrier concept has been adopted for disposal that combines the containment provided by the structural, hydraulic and geochemical characteristics of the rock mass with a series of engineered barriers. The conceptual disposal vault consists of an array of disposal rooms excavated in plutonic rock at a depth between 500 and 1000 m. Prior to disposal, the waste would be placed in cylindrical containers surrounded by a buffer, which is a mixture of bentonite cla and sand. The rooms would be backfilled with mixture of clay, and crushed granite or san. Bulkheads would seal the entrances. Closure would be achieved by backfilling the access tunnels in the same manner as the rooms and than backfilling the shafts with compacted clay and crushed granite separated by a series of supporting bulkheads. Very preliminary results from the case study indicate that the good rock provides the most effective barrier to movement of radionuclides to the surface. The most significant pathways through the geosphere involve diffusion through the good rock to the major fracture intersecting the vault, convection upward along the fracture, and discharge either at topographic lows or through a domestic water supply well used by the critical group. Long-lived non-sorbing radionuclides, available in the gaps between the fuel pellets and the fuel cladding or at the grain boundaries, contribute most to the radiological dose. With appropriate constraints on the location of the waste packages relative to the major fracture zones, radiological risk is expected to satisfy the regulatory criteria. (H.W.) 5 figs

Pharmacists have a long history of helping Canadians with minor ailments. This often has involved management with over-the-counter medications. If pharmacists felt that the best care required something more robust, they would refer the patient to a physician. In hopes of improving the care of such ailments, Canadian provinces have granted pharmacists the option of selecting medications traditionally under physician control. This review examines the Canadian perspective on pharmacists prescribing for minor ailments and the evidence of value for these programs. It might provide guidance for other jurisdictions contemplating such a move. PMID:27570460

Established in the early 1970s, EdGEO supports locally driven geosciences workshops for Canadian teachers. Workshops are organized by geoscientists and teachers, and typically have field, laboratory and classroom components. Grants of up to $3000 per workshop are available from the National EdGEO Program. By providing educational opportunities for today's teachers and, through them, their students, EdGEO seeks to cultivate a heightened awareness of our planet. EdGEO workshops provide teachers with potential fieldtrip sites for their students and the knowledge, enthusiasm and materials to inspire their students to engage in geoscience. Networking opportunities with local experts promote the importance of the geoscience profession. The expected result is an improved capacity on the part of Canadians to understand the Earth and to make informed decisions, especially with regard to the use of mineral and energy resources, the maintenance and remediation of the environment, and response to geological hazards. There exists a critical need to provide teachers with training and resources to tackle their Earth science curricula. In 2008, EdGEO supported fourteen workshops, with an unprecedented 521 teachers attending. These teachers then used our resources to reach an estimated 14,000 students during that single academic year. EdGEO workshops are locally driven and are therefore very diverse. Workshops are strongly tied to the provincial curriculum, focus on a specific geoscience topic, or may be largely field-based to demonstrate and practice how field activities could be incorporated into Earth science teaching. Many strive to include all of these important components. Geoscientists and teachers work collaboratively to develop and deliver EdGEO workshops to ensure that the activities can be effectively used in the classroom. The length of these professional development opportunities range from two-hour sessions to several days, and can generally accommodate up to twenty

Clinical investigators within the Canadian and international communities were shocked when the Canadian Institutes of Health Research (CIHR) announced that their funding for the MD/PhD program would be terminated after the 2015-2016 academic year. The program has trained Canadian clinician-scientists for more than two decades. The cancellation of the program is at odds with the CIHR's mandate, which stresses the translation of new knowledge into improved health for Canadians, as well as with a series of internal reports that have recommended expanding the program. Although substantial evidence supports the analogous Medical Scientist Training Program in the United States, no parallel analysis of the MD/PhD program has been performed in Canada. Here, we highlight the long-term consequences of the program's cancellation in the context of increased emphasis on translational research. We argue that alternative funding sources cannot ensure continuous support for students in clinician-scientist training programs and that platform funding of the MD/PhD program is necessary to ensure leadership in translational research.

The framework of a Canadian-developed parent education program, Nobody's Perfect, was used in the development of a new parent education program offered to parents attending a child nutrition rehabilitation program in the Dominican Republic. While key teaching elements of the original program were retained (e.g., encouraging active participation, emphasizing facilitation over didactic teaching, using experiential learning), locally relevant content was inserted (e.g., diarrhea prevention and treatment strategies). A Canadian team trained a group of Dominicans to deliver the new program to parents of children recovering from malnutrition. This paper describes the development, implementation, and resulting parenting program from this effort. This 8-week program may find use in other settings. In addition, the experience gained from this exportation endeavor may be useful for others undertaking similar initiatives. PMID:19261157

Canada has experienced a substantial reduction in mortality related to cardiovascular disease (CVD). There is a general consensus that more effective and widespread health promotion interventions may lead to further reductions in CVD risk factors and actual disease states. In this paper, we briefly outline the prevalence of selected risk factors for CVD in Canada, describe characteristics of the Canadian labor market and workforce, and depict what is known about health and wellness program delivery systems in Canadian workplaces. Our review indicates that there have been numerous and diverse relevant legislative and policy initiatives to create a context conducive to improve the healthfulness of Canadian workplaces. However, there is still a dearth of evidence on the effectiveness of the delivery system and the actual impact of workplace health and wellness programs in reducing CVD risk in Canada. Thus, while a promising model, more research is needed in this area. PMID:24607012

This paper summarizes the performance and operating experience of CANDU fuel in Canadian CANDU reactors in 1999 and 2000. The extremely low rate of fuel defects continues to demonstrate that CANDU fuel is performing exceptionally well. Over the 2-year period, the fuel bundle defect rate for all bundles irradiated in Canadian CANDU reactors has remained very low, between 0.011% (suspected defects) and 0.007% (confirmed defects). On a fuel element basis, this represents a rate of confirmed defects of about 0.0002%; this rate is approaching 2 defects per million fuel elements! This successful performance is the result of a number of contributing factors, including a simple and robust fuel design with conservative design margins, reliable and specialized manufacturing processes that have been developed over the years, and fuel operations that conform to the fuel operating limits. Strong linkages between plant operation, designers, and Canadian fuel research and development programs also contribute to the high performance of the current CANDU fuel. The Fuel Design and Performance program, funded by the CANDU Owners Group, addresses licensing and operational issues that are common to the Canadian CANDU utilities. In addition, AECL's Fuel and Fuel Cycles working group directs R and D to support evolutionary improvements to the fuel products, as well as longer-term R and D for advanced fuel concepts. This paper describes the development programs in 1999/2000. (author)

Full text: The Canadian Safeguards Support Program (CSSP) is one of the first safeguards support programs with an overall objective to assist the IAEA by providing technical assistance and other resources and by developing equipment to improve the effectiveness of international safeguards. This paper provides a brief discussion of the evolution of the CSSP, from the beginning when the program was under joint management between the Atomic Energy Control Board (AECB) and Atomic Energy of Canada Limited (AECL), a Canadian crown corporation, until recent years when the AECB became responsible for all projects and financial management. Recently, new legislation came into force and the AECB became the Canadian Nuclear Safety Commission (CNSC). However, the mandate and management of the CSSP under the CNSC remain fundamentally unchanged. Major CSSP activities are devoted to the following areas: (a) Human resource assistance through the provision of cost-free experts (CFEs) to the IAEA; (b) Training of IAEA inspectors and facility operators, development of training resources and integrated approaches for training; (c) System studies, e.g. the development of integrated safeguards approach for CANDU reactors, geological repository, and physical model; (d) Equipment development, e.g. the VXI Integrated Fuel Monitor, Digital Cerenkov Viewing Device, seals, remote monitoring, encryption and authentication; (e) Information technology which includes satellite imagery, Geographical Information System (GIS), and position tracking of spent fuel containers. The CSSP has continued to evolve during the past 25 years. Although formerly larger the CSSP budget has settled to a stable level of just slightly above (Canadian) $2M. Leveraging of the CSSP budget through collaborations with several Member State Support Programs and Canadian government departments has provided mutual benefits for all parties involved and useful results that have been put into practical use by the IAEA.

This paper describes the CANDU fuel development activities in Canada during 1997 through 1998. The activities include those of the Fuel Technology Program sponsored by the CANDU Owners Group. The goal of the Fuel Technology Program is to maintain and improve the reliability, economics and safety of CANDU fuel in operating reactors. These activities, therefore, concentrate on the present designs of 28-element and 37-element fuel bundles. The Canadian fuel development activities also include those of the Advanced Fuel and Fuel Cycle Technology Program at AECL. These activities concentrate on the development of advanced fuel designs and advanced fuel cycles, which among other advantages, can reduce the capital and fuelling costs, maintain operating margins in aging reactors, improve natural-uranium utilization, and reduce the amount of spent fuel.

In the early 1980`s the Canadian Coast Guard began a solarization program to power its navigation aids in an effort to eliminate the use of primary batteries and to cut the cost and environmental impact of expensive diesel generators. Currently, the replacement of batteries is just about complete. Over 5,500 navigational aids run on solar power. The power output ranges from 10 watts to 2,400 watts. 99 per cent of the solar systems are stand-alone photovoltaic systems with an average output capacity of 40 watts. The solar systems have operated satisfactorily under cold climate conditions. It was estimated that the Coast Guard has saved tens of millions of dollars through this conversion effort. 2 figs.

In 2006, Atomic Energy of Canada Limited (AECL) and Natural Resources Canada (NRCan) began implementing a $7B CDN, 70-year Nuclear Legacy Liabilities Program (NLLP) to deal with legacy decommissioning and environmental issues at AECL nuclear sites. The objective of the NLLP is to safely and cost-effectively reduce the nuclear legacy liabilities and associated risks based on sound waste management and environmental principles in the best interest of Canadians. The liabilities include shutdown research and prototype power reactors, fuel handling facilities, radiochemical laboratories, support buildings, radioactive waste storage facilities, and contaminated lands at several sites located across eastern Canada from Quebec to Manitoba. The largest site, Chalk River Laboratories (CRL) in Ontario, will continue as an operational nuclear site for the foreseeable future. Planning and delivery of the Program is managed by the Liability Management Unit (LMU), a group that was formed within AECL for the purpose. The composition and progress of the NLLP has been reported in recent conferences. The NLLP comprises a number of interlinked decommissioning, waste management and environmental restoration activities that are being executed at different sites, and by various technical groups as suppliers to the LMU. Many lessons about planning and executing such a large, diverse Program have been learned in planning the initial five-year 'start-up' phase (which will conclude 2011 March), in planning the five-year second phase (which is currently being finalized), and in planning individual and interacting activities within the Program. The activities to be undertaken in the start-up phase were planned by a small group of AECL technical experts using the currently available information on the liabilities. Progress in executing the Program was slower than anticipated due to less than ideal alignment between some planned technical solutions and the actual requirements, as well as the
Purpose: To develop a non-invasive method for detection of acetabular cup migration after total hip arthroplasty (THA) with a higher degree of accuracy than routine plain radiography. Material and Methods: Two CT examinations, 10 min apart, were obtained from each of 10 patients that had undergone THA. Using an in-house developed semiautomated program for volume merging, the pelves in the two examinations were fused and the acetabular cup was visually and numerically evaluated to test the method's accuracy in detecting migration. Results: In the visual evaluation of the best match a 1-mm translation of the cup was detectable. The numerical evaluation, comparing landmarks placed in the images of the acetabular cup and the head of the femur component in the two examinations, showed the mean difference in orientation of acetabular axes to be 2.5 deg, the mean distance between centre of cup face to be 2.5 mm and the mean distance between centre of the head of the prosthetic femoral component to be 1 mm. Conclusion: This method has a significantly higher accuracy than routine plain radiography in detecting acetabular cup migration and could be used in clinical practice. It gives both a visual and a numerical correlate to migration
Full Text Available Abstract Background Total knee arthroplasty (TKA is a commonly performed surgical procedure in the US. It is important to have a comprehensive inpatient TKA program which maximizes outcomes while minimizing adverse events. The purpose of this study was to describe a TKA program – the Joint Replacement Program (JRP – and report post-surgical outcomes. Methods 74 candidates for a primary TKA were enrolled in the JRP. The JRP was designed to minimize complications and optimize patient-centered outcomes using a team approach including the patient, patient's family, and a multidisciplinary team of health professionals. The JRP consisted of a pre-operative class, standard pathways for medical care, comprehensive peri-operative pain management, aggressive physical therapy (PT, and proactive discharge planning. Measures included functional tests, knee range of motion (ROM, and medical record abstraction of patient demographics, length of stay, discharge disposition, and complications over a 6-month follow-up period. Results All patients achieved medical criteria for hospital discharge. The patients achieved the knee flexion ROM goal of 90° (91.7 ± 5.4°, but did not achieve the knee extension ROM goal of 0° (2.4 ± 2.6°. The length of hospital stay was two days for 53% of the patients, with 39% and 7% discharged in three and four days, respectively. All but three patients were discharged home with functional independence. 68% of these received outpatient physical therapy compared with 32% who received home physical therapy immediately after discharge. Two patients ( Conclusion The comprehensive JRP for TKA was associated with satisfactory clinical outcomes, short lengths of stay, a high percentage of patients discharged home with outpatient PT, and minimal complications. This JRP may represent an efficient, effective and safe protocol for providing care after a TKA.

Since the introduction of the 1999 Canadian Cabinet Directive on the environmental assessment of policies, plans, and programs (PPPs), higher-order environmental assessment has been receiving increased attention in Canada. However, while practices and systems are advancing at the federal level, there has been very little attention given to recent developments in PPP assessment at the provincial level. This paper presents the results of a Canada-wide survey of PPP assessment principles and practices in 10 Canadian provincial EA jurisdictions. The findings indicate that there exists considerable variability in the provisions for and practice of PPP assessment amongst Canadian provinces, with only Saskatchewan, Ontario, and Quebec identifying recent practice experience. Included amongst the main barriers to effective implementation at the provincial level are the lack of legislative requirements for strategic EA, and the limited understanding of the nature and benefits of higher-order impact assessment
Existing alternative transportation programs and initiatives in Canada were presented as part of an effort to achieve the Canada-Wide Standards on Particulate Matter and Ground-level Ozone. This document is intended for employers that could implement support services in their workplace that promote methods of commuting that reduce vehicle kilometers traveled and encourage alternative transportation to the single occupant vehicle with the objective or reducing particulate matter and ground-level ozone. Alternative transportation programs such as employers programs, youth programs and institutional programs have environmental, economic, social and community benefits such as reduced emissions and greater transportation efficiency which lead to improved quality of life, health and sustainability of the transportation system. Organizations implement alternative transportation programs because of a commitment to; environmental responsibility, improving air quality, offering employee benefits, GHG reductions and corporate leadership. The programs are often initiated by large urban centres experiencing transportation-related problems such as congestion, air pollution or infrastructure capacity constraints. The U-Pass was presented as example of a very successful program that promotes change in behaviour at institutions to increase transit ridership. Telework also offers the opportunity of eliminating commutes. Ridematching is another key marketing tool employed by many organizations. The most successful programs are those with the greatest financial resources because sustained funding is necessary for program delivery, expansion and community acceptance. refs., tabs., figs.

Family physicians may spend up to 50% of their time diagnosing and managing mental disorders and emotional problems, but this is not always reflected in the training they receive. This study of the teaching of psychiatry in the 16 family medicine residency programs in Canada showed that although the majority of program directors are reasonably satisfied with the current training, they see room for improvement—particularly in finding psychiatrists with a better understanding of family practice...

Methodology: As a comparator, a cross-sectional survey involving 76 Saudi residents from different training centers in Saudi Arabia namely; Riyadh, Jeddah, Medina, Abha, and Dammam and 15 Canadian. Results: The results showed that Canadian residents read more peer-reviewed, scholarly articles compared with Saudi residents (P=0.002. The primary surgical role for residents was to hold retractors during surgery. The survey respondents strongly supported the ability to recommend removal of incompetent trainers. Saudi trainees were more apprehensive of examinations than Canadian trainees (P<0.0001. Most residents preferred studying multiple-choice questions before examinations. Saudi and Canadian participants considered their programs to be overcrowded. Unlike Canadian participants, Saudi trainees reported an inadequate level of training (P<0.0001. Conclusion: Educational resources should be readily accessible and a mentorship system monitoring residents' progress should be developed. The role of the resident must be clearly defined and resident feedback should not be ignored. Given the importance of mastering basic orthopedic operative skills for residents, meaningful remedial action should be taken with incompetent trainers. Keywords: evaluation, medical education, orthopedic board, residency program, training
The Canadian Nuclear Fuel Waste Management Program involves research into the storage and transportation of used nuclear fuel, immobilization of fuel waste, and deep geological disposal of the immobilized waste. The program is now in the fifth year of a ten-year generic research and development phase. The objective of this phase of the program is to assess the safety and environmental aspects of the deep underground disposal of immobilized fuel waste in plutonic rock. The objectives of the research for each component of the program and the progress made to the end of 1984 are described in this report. 74 refs
Atomic Energy of Canada Limited (AECL) has developed a concept for permanent geological disposal of nuclear fuel waste in Canada. An accelerated program was initiated in 1991 to address and quantify the potential effects of microbial action on the integrity of the disposal concept's multiple barrier system. This microbial program focuses on answering specific questions in areas such as the survival of bacteria in compacted clay-based buffer materials under relevant radiation and desiccation conditions; mobility of microbes in compacted buffer materials; the potential for microbially-influenced corrosion of containers; microbial gas production in backfill material; introduction of nutrients as a result of vault excavation and operation; the presence and activity of microbes in deep granitic groundwaters; and the effects of biofilms on radionuclide migration in the geosphere. This paper summarizes the current research activities at AECL in these areas. (author)
Chemistry program is one of the essential programs for the safe operation of a nuclear power plant. It helps to ensure the necessary integrity, reliability and availability of plant structures, systems and components important to safety. Additionally, the program plays an important role in asset preservation, limiting radiation exposure and environmental protection. A good chemistry program will minimize corrosion of materials, reduce activation products, minimize of the buildup of radioactive material leading to occupational radiation exposure and it helps limit the release of chemicals and radioactive materials to the environment. The legal basis for the chemistry oversight at Canadian NPPs is established by the Nuclear Safety and Control Act and its associated regulations. It draws on the Canadian Nuclear Safety Commission's regulatory framework and NPP operating license conditions that include applicable standards such as CAN/CSA N286-05 Management System Requirements for Nuclear Power Plants. This paper focuses on the regulatory oversight strategy used in Canada to assess the performance of chemistry program at the nuclear power plants (NPPs) licensed by CNSC. The strategy consists of a combination of inspection and performance monitoring activities. The activities are further supported from information gathered through staff inspections of cross-cutting areas such as maintenance, corrective-action follow-ups, event reviews and safety related performance indicators.

Full Text Available Abstract Background At a time of increased need and demand for general internists in Canada, the attractiveness of generalist careers (including general internal medicine, GIM has been falling as evidenced by the low number of residents choosing this specialty. One hypothesis for the lack of interest in a generalist career is lack of comfort with the skills needed to practice after training, and the mismatch between the tertiary care, inpatient training environment and "real life". This project was designed to determine perceived effectiveness of training for 10 years of graduates of Canadian GIM programs to assist in the development of curriculum and objectives for general internists that will meet the needs of graduates and ultimately society. Methods Mailed survey designed to explore perceived importance of training for and preparation for various aspects of Canadian GIM practice. After extensive piloting of the survey, including a pilot survey of two universities to improve the questionnaire, all graduates of the 16 universities over the previous ten years were surveyed. Results Gaps (difference between importance and preparation were demonstrated in many of the CanMEDS 2000/2005® competencies. Medical problems of pregnancy, perioperative care, pain management, chronic care, ambulatory care and community GIM rotations were the medical expert areas with the largest gaps. Exposure to procedural skills was perceived to be lacking. Some procedural skills valued as important for current GIM trainees and performed frequently (example ambulatory ECG interpretation had low preparation ratings by trainees. Other areas of perceived discrepancy between training and practice included: manager role (set up of an office, health advocate (counseling for prevention, for example smoking cessation, and professional (end of life issues, ethics. Conclusion Graduates of Canadian GIM training programs over the last ten years have identified perceived gaps

In December of 1983, Systemhouse Ltd. was awarded a contract to collect data relevant to the Canadian National Uranium Tailings Program and to convert it into a machine readable format. The work was carried out in four phases, namely, data identification, data collection, data transcription/conversion and data verification. The main priority was to identify as much relevant data as possible. The identified data was priorized against a predefined criteria established in conjunction with the project scientific authority. A total of 428 studies were identified as being relevant. Data from 19 of these were converted to machine-readable format, giving information on 2398 samples from 78 boreholes
A partnership between the Canada Centre for Mineral and Energy Technology (CANMET) Energy Technology Centre (CETC) of Natural Resources Canada (NRCan), and the Canadian coal and steel industries, the Canadian Carbonization Research Association (CCRA) which conducts research and development activities with its partners. This document summarizes the economic and environmental impacts of the research and development program administered by the CCRA. More than 25 research programs have been undertaken by the CCRA since it was established in 1964. The activities dealt with specific technical challenges which the Canadian coal industry faced with regard to the production and marketing of metallurgical coal, as well as the uses of coal and alternative fuels such as natural gas to make coke used in blast furnaces. The report detailed the scope of CETC's energy for high temperature processes, then addressed program resources and study methodology. Three categories of impacts were discussed: general-level impacts, economic and environmental impacts, and quantitative estimates of economic impacts. The attribution of impacts was examined and future directions were examined in the last section of the report. It was determined that CETC participation in the research program is still required, due to the fact that it is Canada's only technical support available to the Canadian coking coal industry. The survival of Canadian coal producers owes something to the economic impacts derived from the CCRA under the current decreasing metallurgical coal prices conditions. 2 tabs
The Canadian program for the development and evaluation of processes and technology for the separation and containment of radioactive species in off-gases is directed towards the following specific aspects: 1) assessment of available treatment technology and evaluation of future clean-up requirements; 2) development and engineering evaluation, under realistic conditions, of promising new processes that would be inherently simpler and safer; and 3) specification of off-gas emission control systems for future nuclear facilities based on the most favourable technology. The program is being carried out by Atomic Energy of Canada Limited in collaboration with the electrical utility, Ontario Hydro, and selected Canadian universities. A brief description is presented of methods for removing tritium and carbon-14 from the moderator systems of CANDU power reactors, methods for removing iodine from the off-gases of a molybdenum-99 production facility at the Chalk River Nuclear Laboratories, and procedures for monitoring the off-gas effluent composition in the Thorium Fuel Reprocessing Experiment (TFRE) facility at the Whiteshell Nuclear Research Establishment
The window and door industry in North America have a strong interest in harmonizing US and Canadian rating procedures and standards for predicting the thermal performance of their products. The costs and time associated with complying with the requirements in both countries are significant and could be reduced through reciprocity. The purpose of this paper is to compare the US and Canadian rating programs. Joint efforts between the US and Canada can use this information to focus on reconciling the differences and to work towards reciprocity. The following identifies the applicable procedures and standards for both countries, and summarizes the major differences in the products that are covered, the sizes that are used, the U-factor and solar heat gain coefficient calculational and test methods, air leakage measurement, prediction of annual energy use, condensation resistance methods, reporting requirements, and accreditation and certification programs. The major differences between the system s are identified and recommendations are made to achieve reciprocity. The appendix contains a paper that is a synopsis of the findings from this study.
The Canadian Space Station User Development Program (UDP), formally approved in March 1986, is gradually approaching maturity. As a result of limited funding, it is also approaching saturation. The remaining UDP budget is $60 million and there are no funds to build space-qualified hardware. Successful microgravity experiments in aircraft have shown that 20 seconds of microgravity are adequate for doing useful science in most cases. Spinoffs have already occurred through applications of patents for processes discovered during microgravity related work. A number of unsuccessful attempts have been made to establish drop-tube test facilities in Canada, and efforts are being made within UDP to acquire first-hand knowledge of such facilities through cooperative programs with other countries. A microgravity rocket was scheduled for a fall 1991 launch but enough experiments may not be found. The CANEX 2 flight on the space shuttle is already fully subscribed, and Canadian scientists are slowly beginning to get aboard the shuttle as co-investigators. It has been decided to book one locker on the October 1993 SPACEHAB flight. Over the long term, the high costs of participating in the space station are of concern. It is recommended that the UDP continue with its microgravity work but only use the space station on an as-required basis.
Purpose: Validation of a non-invasive CT method for detection of acetabular cup migration after total hip arthroplasty in a phantom study. Material and Methods: 26 CT examinations were obtained of a pelvic model while altering the position of the acetabular cup. Using a previously described program for volume merging, the pelvi in different examinations were fused and the 3D alterations of the position of the acetabular cup were evaluated visually and numerically and correlated to direct measurements on the model. Results: Visually, two independent examiners differentiated between 0, 1 and 2 to 3 mm migration with 100% specificity and sensitivity. Numerically, the mean error over all cases between model and CT measurements was 0.04 mm (SD ± 0.33). The mean absolute error between model and CT data was 0.26 mm (SD ± 0.19). Intra- and interobserver 95% accuracy and repeatability limits were below 0.5/0.7 mm, respectively. No significant interobserver difference occurred. The data were normally distributed and not dependent on observer. Conclusion: The accuracy of this non-invasive method out-performs routine plain radiography. The method gives both visual and numerical correlates to migration and can be used in clinical practice

Total knee arthroplasty (TKA) is a surgery consisting on the artificial joint replacement, due to a traumatic injury or a degenerative process or arthrosis. This surgery causes an important pain to patients, and sometimes affects negatively on their recovery. The choice of the prostheses will depend on the anatomical features of the patient and the surgeon criterion. The concept of a "rapid recovery surgery" was introduced in 1997 by Khelet and meant the beginning of the Fast Track model or the Rapid Recovery (RR) linked to an accelerated rehabilitation, an early discharge and the optimization of all the aspects of pre, intra and post-operative patient experience. Fast recovery is a surgical process which aims to achieve maximum autonomy of the patient through education, pain control and early mobilization. The key of the rapid recovery is to get the involvement of the patient thanks to the empowerment, which means a preoperative patient education that will help to reduce anxiety and it will make easier to engage in their own recovery. Furthermore the patient will take part of an effective post-operative physical therapy, using all the necessary tools to increase their ability to manage their own health problems. The empowerment of these patients is part of the Nursing Model in the Hospital Clinic de Barcelona (HCB), adopted by the Nursing Management in December of 2012. In Catalonia, until the start of the RR surgery, 14,132 interventions in 2008 where done by TKA conventional surgery, needing subsequent conventional hospitalization. This article describes the care and outcomes of nurse interventions, defined in the RR of TKA clinical way, which is focused on the pain's minimization and the impact on patients' mobilization. It was performed in a monographic unit from a tertiary-level hospital in Barcelona in 2013. PMID:26591937
A review is presented of results of the Canadian Climate Impacts Program series of studies examining the socio-economic impacts of climate change. In the Great Lakes basin, climate change may impact on numerous economic sectors. Lower lake levels could result in increased dredging of ports and channels or reduced cargo loads. Lower lake levels added to increased use of water could result in a loss of 4,165 GWh of power generation for the Canadian hydro-electric generating stations on the Great Lakes. A warmer climate may lead to crop failures in the agricultural heartlands of Ontario, as the advantages of higher temperature may be offset by moisture stress. The downhill ski industry may be decimated in southern Ontario. Rising sea levels may cause increased risk of storm surges and river flooding in the coastal areas of Canada. A warmer climate would probably be beneficial to aquaculture and allow longer inshore fishing seasons. Costs to oil and gas exploration due to sea ice and icebergs would be practically eliminated. Results for the Praire provinces were mixed: one study concluded that impacts would be minimal while another predicted a moderate reduction in spring wheat potential. 24 refs., 1 fig

A questionnaire was mailed to all 62 unit and program directors of Canadian family practice residency programs to elicit details about the status of nutrition education. Although most respondents indicated that the registered dietitian was the primary person responsible for teaching nutrition, this responsibility comprised only 10% of the dietitian's time in most programs. Lack of funding and curriculum time were the most common reasons cited for the limited scheduling that the dietitian was ...
Maintaining adequate safety and reliability of nuclear power plants and nuclear power plant life assurance and life extension are growing in importance as nuclear plants get older. Age-related degradation of plant components is complex and not fully understood. This paper provides an overview of the Canadian approach and the main activities and their results towards understanding and managing age-related degradation of nuclear power plant components, structures and systems. A number of pro-active programs have been initiated to anticipate, detect and mitigate potential aging degradation at an early stage before any serious impact on plant safety and reliability. These programs include Operational Safety Management Program, Nuclear Plant Life Assurance Program, systematic plant condition assessment, refurbishment and upgrading, post-service examination and testing, equipment qualification, research and development, and participation in the IAEA programs on safety aspects of nuclear power plant aging and life extension. A regulatory policy on nuclear power plants is under development and will be based on the domestic as well as foreign and international studies and experience
Canada currently has 18 CANDU Pressurized Heavy Water Reactors in operation and 4 under construction, for an installed nuclear capacity of 15,500 MWe. Most of the reactors are in the province of Ontario where 50% of the electricity is nuclear generated. Atomic Energy of Canada is developing the CANDU-3, a 450 MWe reactor incorporating the latest available technologies, including distributed control. The three Canadian Utilities with CANDU reactors have made a major commitment to full-scope training simulators. In Canada there is a growing commitment to developing major improvements to the interface between the control systems, the field equipment and the operating staff. The development program underway makes extensive use of information technology, particularly expert systems and interactive media tools. Out of this will come an advanced CANDU control concept that should further improve the reliability and availability of CANDU stations. (author). 3 refs

RENEL (Romania Power Authority), the co-ordinator of Romanian Nuclear Program, have decided to improve, starting 1990 the existing capability to produce CANDU nuclear fuel at FCN Pitesti. The objective of the program was defined with AAC (AECL - ANSALDO Consortium) for the qualification of FCN fuel plant according to Canadian Z299.2 standard. The Qualification Program was performed under AAC Work Order C-003. The co-ordination was assumed by AECL, as overall Design Authority. ZPI (Zircatec Precision Industries Inc., Canada), were designated to supply technical assistance, equipments and know how where necessary. After a preliminary verification of the FCN fuel plant, including the processes and system investigation, performed under AECL and ZPI assistance, the Qualification Program was defined in all details. The upgrading of documentation on all aspects required by Z299.2 was performed. Few processes needed to be reconsidered and equipment was delivered by ZPI or other suppliers. This includes mainly welding equipments and special inspection equipments. Health Physics was practically fully reconsidered. New equipment and practice were adapted to provide adequate control on health conditions. Every manufacturing and inspection process was checked to determine their performance during a Qualification Run based on acceptance criteria which have been established in the Qualification Plan. Manufacturing Demonstration Run was an important step to prove that all plant functions have been accomplished during the fabrication of 200 fuel bundles. These bundles have been fully accepted and 66 of them have been loaded in the first charge of Unit 1 Cemavoda NPS. The surveillance and audit actions made by AECL and ZPI during this period confirmed the FCN capability to operate an adequate system meeting the to required quality assurance standard. The very open attitude of AECL, Zircatec and FCN staff have stimulated the progress of the project and a successful achievement of the
The paper reviews the current state of nuclear engineering postgraduate education in Canada, with emphasis on the new courses and programs that have been introduced since PBNC2006. The importance of these developments is presented against a background of the aging of the reactor fleet that came into operation in the 1970s, 1980s and early 1990s, along with the changing training needs and demographics of the nuclear industry. The demand for nuclear engineers continues to grow in order to operate, maintain, upgrade and refurbish the existing units, as well as to design, construct, commission and operate the new reactors that are being proposed in Canada and abroad. Responding to this demand, a consortium of key Canadian nuclear companies, and universities that conduct research and offer postgraduate courses in nuclear engineering, have formed UNENE (University Network of Excellence in Nuclear Engineering). In addition to funding research chairs at seven universities in Ontario, UNENE offers a course-based master of nuclear engineering program. In this way, industry funding has effectively revitalized existing, and initiated new, nuclear programs at established universities. In addition, one of the UNENE partners, the newly established University of Ontario Institute of Technology (UOIT), is offering both research and course-based master of nuclear engineering programs as of September 2008. Based on the experiences of UNENE and UOIT the paper explores the gap between the mandates of universities and the nuclear industry, collectively and individually. It is shown that by recognizing the differences and capitalizing on their respective strength, the graduate and postgraduate educational programs conducted by universities can be effective to complement the training and experience that only the industry can offer.

The Canadian Nuclear Safety Commission (CNSC) is the principal nuclear regulator in Canada. The CNSC is empowered through the Nuclear Safety and Control Act (NSCA) and its associated regulations, to regulate the entire nuclear cycle which includes: uranium mining and milling, uranium refining and processing, fuel fabrication, power generation and nuclear waste management. A CNSC uranium mine licence is required by a proponent to site, prepare, construct, operate, decommission and abandon this nuclear facility. The CNSC licence is the legal instrument that authorizes the regulated activities and incorporates conditions and regulatory controls. Following a favourable Commission Tribunal decision to issue a licence to authorize the licensed activities, CNSC develops and executes a compliance plan of the licensee’s programs and procedures. The CNSC compliance plan is risk-informed and applies its resources to the identified higher risk areas. The compliance program is designed to encourage compliance by integrating three components: promotion, verification and enforcement and articulates the CNSC expectations to attain and maintain compliance with its regulatory requirements. The licensee performance is assessed through compliance activities and reported to the Commission to inform the licensing process during licence renewal. The application of the ongoing compliance assessment and risk management model ensures that deviations from impact predictions are addressed in a timely manner. The Uranium Mines and Mills Division of the CNSC are preparing to meet the challenges of the planned expansion of their Canadian uranium mining industry. The presentation will discuss these challenges and the measures required to address them. The Uranium Mines and Mills Division (UMMD) have adopted a structured compliance framework which includes formal procedures to conduct site inspections. New UMMD staff are trained to apply the regulations to licensed sites and to manage non

Full Text Available On June 18, 2015, the Canadian Institutes of Health Research (CIHR announced that it would terminate funding to M.D.-Ph.D. programs due to budget constraints, against the recommendations from two advisory panels. CIHR’s M.D.-Ph.D. program grants, which amounted to an annual average of $1.8 million in the form of 14 six-year studentships, represent only 0.15% of CIHR’s $1.2 billion operating budget. As over half of M.D.-Ph.D. trainees are dependent on these studentships, this poses a threat to physician-scientist training in Canada. In response to the current volatile funding climate, we surveyed McGill University’s M.D.-Ph.D. program alumni to assess its success in producing physician-scientists. In this program, 60.0% of graduates who have completed training have become physician-scientists, the majority being retained in Canada. These individuals have attained positions with sufficiently protected time for research and had grant success and significant publications for early- to mid-career investigators. This suggests that the current M.D.-Ph.D. system is an effective way of producing competent physician-scientists. As physician-scientists have remarkably contributed to Canadian healthcare innovation despite making up a fraction of physicians and researchers, vulnerability in the M.D.-Ph.D. pipeline would invariably affect the health of Canadians.
This annual report provides a comprehensive review of the Canadian electricity industry's environmental performance in 2001. In 1997 the Canadian Electricity Association launched the Environmental Commitment and Responsibility (ECR) Program which is based on individual initiatives of member utilities. The program is designed to address the industry's commitment to sustainable development and better environmental performance. This annual report focuses on air quality issues for the electricity industry with emphasis on energy efficiency and the challenge of climate change. Member utilities are developing and deploying alternative energy technologies, such as wind, solar, ground source heat pumps, and small run of river hydro electric power. These sources are becoming more cost competitive and have potentially less impact on the environment. The industry is also enhancing the many different fuel types available throughout Canada. Environmental performance highlights and trends for the year 2001 were also presented for each member utility. tabs., figs
The present Canadian nuclear power program based on the CANDU-PHW reactor, future commitments, and the status of heavy water production, are discussed, together with short term prospects over the next 20 years. The longer term favours fuels with higher fissile content than natural uranium. Possible future strategies are discussed, which include consideration of a number of different fuel cycles for the different types of CANDU reactor, i.e. CANDU-PHW, CANDU-BLW, CANDU-PLW and CANDU-OCR. It is concluded that: CANDU-PHW reactor is fully reliable and competative; organic and boiling water cooled variations promise savings of 15 to 20% in both capital and unit energy costs; the CANDU concept offers the opportunity for large improvements in uranium conservation whilst remaining economically competitive, by use of plutonium recycle and/or thorium; using the CANDU concept with thorium it is possible to limit the total uranium requirement for a given nuclear power capacity; and finally a system based on CANDU-PHW reactors could introduce FBR reactors more quickly and efficiently than one based on LWR reactors.

mellitus or chronic kidney disease (regardless of the degree of proteinuria). Most adults with hypertension require more than one agent to achieve these target BPs. For adults without compelling indications for other agents, initial therapy should include thiazide diuretics. Other agents appropriate for first-line therapy for diastolic hypertension with or without systolic hypertension include beta-blockers (in those younger than 60 years), angiotensin-converting enzyme (ACE) inhibitors (in nonblack patients), long-acting calcium channel blockers or angiotensin receptor antagonists. Other agents for first-line therapy for isolated systolic hypertension include long-acting dihydropyridine calcium channel blockers or angiotensin receptor antagonists. Certain comorbid conditions provide compelling indications for first-line use of other agents: in patients with angina, recent myocardial infarction or heart failure, beta-blockers and ACE inhibitors are recommended as first-line therapy; in patients with diabetes mellitus, ACE inhibitors or angiotensin receptor antagonists (or in patients without albuminuria, thiazides or dihydropyridine calcium channel blockers) are appropriate first-line therapies; and in patients with nondiabetic chronic kidney disease, ACE inhibitors are recommended. All hypertensive patients should have their fasting lipids screened, and those with dyslipidemia should be treated using the thresholds, targets and agents recommended by the Canadian Hypertension Education Program Working Group on the management of dyslipidemia and the prevention of cardiovascular disease. Selected patients with hypertension, but without dyslipidemia, should also receive statin therapy and/or acetylsalicylic acid therapy. VALIDATION All recommendations were graded according to strength of the evidence and voted on by the 45 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force.

OBJECTIVE: To provide updated, evidence-based recommendations for the prevention and management of hypertension in adults. OPTIONS AND OUTCOMES: For lifestyle and pharmacological interventions, evidence was reviewed from randomized controlled trials and systematic reviews of trials. Changes in cardiovascular morbidity and mortality were the primary outcomes of interest. However, for lifestyle interventions, blood pressure lowering was accepted as a primary outcome given the lack of long-term morbidity and mortality data in this field. For treatment of patients with kidney disease, the progression of kidney dysfunction was also accepted as a clinically relevant primary outcome. EVIDENCE: A Cochrane collaboration librarian conducted an independent MEDLINE search from 2005 to August 2006 to update the 2006 Canadian Hypertension Education Program recommendations. In addition, reference lists were scanned and experts were contacted to identify additional published studies. All relevant articles were reviewed and appraised independently by both content and methodological experts using prespecified levels of evidence. RECOMMENDATIONS: Dietary lifestyle modifications for prevention of hypertension, in addition to a well-balanced diet, include a dietary sodium intake of less than 100 mmol/day. In hypertensive patients, the dietary sodium intake should be limited to 65 mmol/day to 100 mmol/day. Other lifestyle modifications for both normotensive and hypertensive patients include: performing 30 min to 60 min of aerobic exercise four to seven days per week; maintaining a healthy body weight (body mass index of 18.5 kg/m2 to 24.9 kg/m2) and waist circumference (less than 102 cm in men and less than 88 cm in women); limiting alcohol consumption to no more than 14 units per week in men or nine units per week in women; following a diet reduced in saturated fat and cholesterol, and one that emphasizes fruits, vegetables and low-fat dairy products, dietary and soluble fibre, whole

Although parenting practices differ across various sociocultural settings, scientific research on parenting intervention in Asia is scarce. We adopted a Canadian multilanguage group-based parenting program (Nobody's Perfect) into the Japanese public health service setting and evaluated its impact. Our program was feasible as a public service; was well-accepted among the participants with low psychological status, many of whom were first-time mothers; and had a potential positive impact on the mood of mothers and the self-evaluation of their abilities in society. Our results may facilitate and provide direction for similar research in Asia. PMID:20526928
no need for undue haste in implementing these. Therefore we can contemplate an orderly research and development program which will put us in a position to adopt one or more of the many options in 10-20 yr time. Since our major uncertainties are in the areas of fuel reprocessing and active fuel fabrication these will be an important part of this program. It is not clear how our experience relates to U.S. problems. Certainly there are many conditions which are quite different in the two countries. The two most important are: (i) We have developed heavy water power reactors and the U.S. has not. (ii) The U.S. has a fast breeder program and we do not. I would like to stress the fact though that we really believe our program is a fully valid alternative (at least for us). We are quite willing then to explore with you the question of whether Canadian experience has any pertinence to problems associated with the U.S. nuclear power program. (author)

This research provides an overview and analysis of graduate level programs, more precisely Masters and Doctorate degrees, offered through faculties of education in Canada. An understanding of the findings of this research may benefit Canadian university administrative bodies in providing a source in which they may compare findings with their current offerings and programming. Prospective students of graduate programs in education may also benefit from the information provided in this study when choosing a program of study by ameliorating their knowledge of current programs, curriculum offerings, and modes of course delivery being offered by faculties of education in Canada.
The Canadian and Swedish Safeguards Support Programs have developed a prototype Digital Cerenkov Viewing Device (DCVD) to verify spent fuel. Field measurements were conducted in January 2003 at the Swedish facilities CLAB and Ringhals Unit 2 on PWR fuel and non-fuel assemblies. The images obtained are documented and the Cerenkov characteristics observed are discussed. New Cerenkov information obtained offers the possibility of computer assisted verification of spent fuel and non-fuel assemblies. Quantitative analysis for parameters such as cooling time, alignment and Cerenkov glow as a function of distance are discussed
Full Text Available This paper seeks to explore health literacies with a focus on public libraries and their patrons. The authors’ aim is to extract major themes, challenges, and recommendations for further research and collaboration between health professionals and information professionals in promoting health literacy skills to the public. Major issues will be discussed on the subjects of public service, education, and collaboration between health specialists and information specialists. A major focus of the paper is Canadian health literacy issues, as well as Canadian health information dissemination. Time constraints and budget cuts in the health care system have caused a major strain on health professionals. Within the system, there is a shortage of doctors, nurses, and time devoted to health literacy. As a result, patients often seek answers to their health concerns on their own and supplement their understanding of individual health issues by searching for information via the Internet. While consumers often seek answers to their health questions online, the lack of quality control on the Internet is problematic. Public librarians should therefore turn their attention to promoting and providing reliable online information. Meeting the needs of any group can be a challenge for information professionals in public libraries, especially when it comes to health literacy. Public libraries tend to be one of the first places of contact for general public inquiries on infectious diseases and emerging illnesses. Public librarians play an important role in their communities in all aspects of information research and therefore should be advocates for promoting proper health information.

Hip arthroplasty has become a common and still increasing procedure for the treatment of osteoarthritis, advanced head necrosis, post-inflammatory arthritis or rheumatoid arthritis.Radiography is the most important imaging modality for monitoring the normal, asymptomatic hip arthroplasty. Radiographs are obtained at the end of a surgical treatment, to exclude complications like fracture or component misplacement. In the follow-up radiographs are used for the diagnosis of loosening and infection of the hip arthroplasty as well as soft tissue ossification. Together with the history and clinical information, the analysis of morphological findings allows to find the grade of loosening. MRI has been advocated in the diagnosis of infection, in particular in the localisation of soft tissue involvement.Imaging, especially by radiographs, is used for the evaluation of the normal and complicated follow-up of hip arthroplasty.

The imaging evaluation of the prosthetic hip begins with radiography, but arthrography, aspiration, scintigraphy, sonography, CT and MR imaging all have roles in the evaluation of the painful prosthesis. This article will review the appearance of normal hip arthroplasty including hemiarthroplasty, total arthroplasty, and hip resurfacing, as well as the appearances of potential complications such as aseptic loosening and osteolysis, dislocation, infection, periprosthetic fracture, hardware failure, and soft tissue abnormalities.

This status report on the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP), an emergency department-based injury and poisoning surveillance system, describes the result of migrating from a centralized data entry and coding process to a decentralized process, the web-based eCHIRPP system, in 2011. This secure system is improving the CHIRPP's overall flexibility and timeliness, which are key attributes of an effective surveillance system. The integrated eCHIRPP platform enables near real-time data entry and access, has user-friendly data management and analysis tools, and allows for easier communication and connectivity across the CHIRPP network through an online collaboration centre. Current pilot testing of automated data monitoring and trend analysis tools-designed to monitor and flag incoming data according to predefined criteria (for example, a new consumer product)-is revealing eCHIRPP's potential for providing early warnings of new hazards, issues and trends.

Full Text Available Scientific background: The annual number of joint replacement operations in Germany is high. The introduction of an arthroplasty register promises an important contribution to the improvement of the quality of patient’s care. Research questions: The presented report addresses the questions on organization and functioning, benefits and cost-benefits as well as on legal, ethical and social aspects of the arthroplasty registers. Methods: A systematic literature search was conducted in September 2008 in the medical databases MEDLINE, EMBASE etc. and was complemented with a hand search. Documents describing arthroplasty registers and/or their relevance as well as papers on legal, ethical and social aspects of such registers were included in the evaluation. The most important information was extracted and analysed. Results: Data concerning 30 arthroplasty registers in 19 countries as well as one international arthroplasty register were identified. Most of the arthroplasty registers are maintained by national orthopedic societies, others by health authorities or by their cooperation. Mostly, registries are financially supported by governments and rarely by other sources.The participation of the orthopedists in the data collection process of the arthroplasty registry is voluntary in most countries. The consent of the patients is usually required. The unique patient identification is ensured in nearly all registers.Each data set consists of patient and clinic identification numbers, data on diagnosis, the performed intervention, the operation date and implanted prostheses. The use of clinical scores, patient-reported questionnaires and radiological documentation is rare. Methods for data documentation and transfer are paper form, electronic entry as well as scanning of the data using bar codes. The data are mostly being checked for their completeness and validity. Most registers offer results of the data evaluation to the treating orthopedists and

Our aim was to compare hip arthroplasty with internal screw fixation in the repair of intertrochanteric fractures in elderly patients with osteoporosis. Of 112 included patient, 70 (81.81 ± 4.88 years) received hip arthroplasty with a prosthesis specially designed for intertrochanteric fractures, and 42 (83.46 ± 5.11 years) underwent plate-screw fixation. The hip arthroplasty group had significantly longer operation time, intraoperative blood loss, and total volume of blood transfused but had shorter time to beginning weight-bearing (5.94 ± 2.76 vs 23.68 ± 22.01 days) and higher postoperative Harris hip score (91.37 ± 4.80 vs 86.14 ± 5.46). In the arthroplasty group, there were 2 dislocations; and in the plate-screw fixation group, there were 5 internal fixation failures. Hip arthroplasty is preferable to internal fixation in elderly patients (age >80 years) with osteoporosis. PMID:21530148

In this qualitative research project, researchers in three Canadian provinces explored the perceptions of many different actors involved in return-to-work (RTW) programs for injured workers, studying their views on successful RTW strategies and barriers to/facilitators of the RTW process, then analyzing the underlying dynamics driving their different experiences. Each research team recruited actors in a variety of different workplaces and key informants in the RTW system, and used a combination of in-depth, semi-structured interviews and focus groups to collect data, which were coded using an open coding system. Analysis took a social constructionist perspective. The roles and mandates of the different groups of actors (injured workers; other workplace actors; actors outside the workplace), while sometimes complementary, could also differ, leading to tension and conflict. Characteristics of injured workers described as influencing RTW success included personal and sociodemographic factors, beliefs and attitudes, and motivation. Human resources managers and health care professionals tended to attribute workers' motivation to their individual characteristics, whereas injured workers, worker representatives and health and safety managers described workplace culture and the degree to which workers' well-being was considered as having a strong influence on workers' motivation. Some supervisors experienced role conflict when responsible for both production quotas and RTW programs, but difficulties were alleviated by innovations such as consideration of RTW program responsibilities in the determination of production quotas and in performance evaluations. RTW program success seemed related to labor-management relations and top management commitment to Health and Safety. Non-workplace issues included confusion stemming from the compensation system itself, communication difficulties with some treating physicians, and role conflict on the part of physicians wishing to

Total knee arthroplasty (TKA) is the most worldwide practiced surgery for knee osteoarthritis and its efficacy is mightily described by literature. Concerns about the invasiveness of TKA let the introduction of segmental resurfacing of the joint for younger patients with localized osteoarthritis. Bone stock sparing and ligaments preservation are the essence of both unicompartmental knee arthroplasty (UKA) and bicompartmental knee arthroplasty (BKA). Advantages related to BKA are the respect of knee biomechanics, lower complications rates, shorter hospital stay, faster rehabilitation. Moreover, in case of failure of the first implant the conversion to TKA is undemanding and can be compared to a standard prosthesis. Our experience suggest that BKA is a reliable technique in selected cases and especially younger people with higher functional requests can favourably profit from it. Although those results are encouraging, we still need further prospective, randomized, long-term studies to finally assess BKA indications and outcomes. PMID:26855941

Full Text Available Abstract Background Knowledge & attitudes of healthcare providers (HCP have significant impact on frequency with which vaccines are offered & accepted but many HCP are ill equipped to make informed recommendations about vaccine merits & risks. We performed an assessment of the educational needs of trainees regarding immunization and used the information thus ascertained to develop multi-faceted, evaluable, educational tools which can be integrated into formal education curricula. Methods (i A questionnaire was sent to all Canadian nursing, medical & pharmacy schools to assess immunization-related curriculum content (ii A 77-item web-based, validated questionnaire was emailed to final-year students in medicine, nursing, & pharmacy at two universities in Nova Scotia, Canada to assess knowledge, attitudes, & behaviors reflecting current immunization curriculum. Results The curriculum review yielded responses from 18%, 48%, & 56% of medical, nursing, & pharmacy schools, respectively. Time spent on immunization content varied substantially between & within disciplines from 50 hrs. Most schools reported some content regarding vaccine preventable diseases, immunization practice & clinical skills but there was considerable variability and fewer schools had learning objectives or formal evaluation in these areas. 74% of respondents didn't feel comfortable discussing vaccine side effects with parents/patients & only 21% felt they received adequate teaching regarding immunization during training. Conclusions Important gaps were identified in the knowledge of graduating nursing, medical, & pharmacy trainees regarding vaccine indications/contraindications, adverse events & safety. The national curriculum review revealed wide variability in immunization curriculum content & evaluation. There is clearly a need for educators to assess current curricula and adapt existing educational resources such as the Immunization Competencies for Health Professionals in

Substantial research illuminates many factors effecting the implementation of evidence-based mental health promotion programs in schools; however, research on how schools plan for sustaining their investments in these programs is limited. In this qualitative study, we elicited descriptions of opportunities and challenges for sustainability. We interviewed 24 individuals from schools involved in a longitudinal, qualitative research project that followed uptake and implementation of the evidence-based WITS Programs across 2 years (Leadbeater et al. 2012). WITS stands for Walk away, Ignore, Talk it out and Seek help and the online WITS Programs focus on preventing peer victimization ( www.witsprograms.ca ). Our findings suggest that sustainability planning in schools is not merely a next step following high quality implementation, but rather involves multiple ongoing processes that need to be anticipated and supported by school leadership and program champions and developers in order to realize investments in evidence-based programs.

The Environmental Commitment and Responsibility (ECR) Program is an industry-wide initiative of the Canadian Electricity Association. The program, launched in 1997, builds on individual initiatives of member utilities and provides a forum to address the industry's commitment to sustainable development and better environmental performance. This annual report focuses on air quality issues for the electricity industry with emphasis on the challenge of airborne mercury and climate change. It also includes a report card from the public advisory panel. In their Letter to the Industry, the panel members expressed their support for the ECR initiative and commended the program participants. This report also presented a series of actions that may be taken to address all of the Panel's recommendations. Some member utilities have put principles into action by developing and deploying alternative energy technologies, such as wind, solar and small run of river hydro electric power. These sources are becoming more cost competitive and have potentially less impact on the environment. The industry is also enhancing the many different fuel types available throughout Canada. Environmental performance highlights and trends for the year 2000 were also presented. While no new trends emerged in 2000, indicators show a continuing and steady improvement in environmental performance in all areas, even with the significant increase in fossil fuel power generation. It was emphasized that in order to meet the rising demand for energy, other measures must be taken, including new capacity and infrastructure, and energy management programs. The increased capital investment for these initiatives will require adequate market prices that reflect the long term value of electrical energy. This report demonstrates the industry's commitment to conduct their business with respect for the natural environment and social expectations. tabs., figs
The Canadian and Swedish Safeguards Support Programs have developed a new digital Cerenkov viewing device (DCVD) to verify spent fuel. The new system, based upon an electron-multiplied charge-coupled device that is lumogen coated, can operate at 14 frames per second using the fast 5 MHz analogue to digital converter. The new DCVD was successful in measuring the long-cooled Aagesta fuel with a burnup of 1,200 MWd/t U and a cooling time of 31 years, which is well below the target of 10,000 MWd/t U and 40- years- cooled. Scanning of fuel assemblies was successfully demonstrated. With the aid of a laser pointer system, random verification within a reasonable time frame was also demonstrated

Despite increases in medical school enrolment, applications to surgical residency programs in Canada have been in decline over the past decade, with an increasing number of unmatched surgical residency positions. We examined the current status of surgical residency in Canada and analyzed application trends (2002–2013) for surgical training programs across Canada. Our findings suggest that most undergraduate medical schools across Canada are having difficulty fostering interest in surgical careers. We propose that a lack of adequate early exposure to the surgical specialties during undergraduate training is a critical factor. Moving forward, we must examine how the best-performing institutions and surgical programs have maintained interest in pursuing surgical careers and adapt our recruitment methods to both maintain and grow future interest. As Mary Engelbreit said, "If you don't like something, change it; if you can't change it, change the way you think about it." PMID:25598177
The major research and development activities in the disposal vault sealing program are buffer development, backfill development, grouting, tunnel and shaft sealing development, and borehole sealing development. The buffer is likely to be a mixture of clay and sand surrounding the waste package and is intended, primarily, to minimize near-field mass transport. The backfill would fill the remainder of the underground workings and most of the volume of the access shafts. Its major component would be crushed rock or sand, or both, with sufficient clay added to achieve the required permeability specification. Boreholes would be sealed throughout their length with low-permeability materials. These may be cements or clays. Shaft seals would be emplaced at specific locations and, probably, would be composed of a low-permeability clay or concrete plug, together with grouting of the rock surrounding the plug. Progress to date and planned future activities for each major part of the program are described. The principal foci of the program are the research and development activities required to assess the concept of underground disposal in plutonic rock and the design and implementation of vault sealing experiments in the Underground Research Laboratory. Program plans are presented that describe the logical progression of each major component of the program, and that indicate the timing of major events that contribute to the final objective of the program, which is to develop engineering specifications for the buffer, backfill and seals, and to justify these specifications in terms of the performance of the waste disposal system. 131 refs

Low levels of literacy in early childhood can have lasting effects on children's educational and intellectual development. Many countries have implemented newborn literacy programs designed to teach parents pre-literacy promoting activities to share with their children. We conducted 2 quasi-experimental studies using 1) a pre-test/post-test design and 2) a non-equivalent control group design to examine the effect of newborn literacy programs on parents' self-reported literacy intentions/behaviors, values toward literacy, and parent-child interactions. Parents were recruited from 3 provinces, 2 with newborn literacy programs (intervention) and 1 without (control). Parents in the intervention group completed prenatal and postnatal (after participation in program) questionnaires. Parents in the control group completed 1 questionnaire. Questionnaires were designed to capture parents' literacy intentions (prenatal), behaviors (postnatal), values, and parent-child interactions (postnatal). A total of 98 parents were included in study one and 174 were included in study two. Parents' self-reported prenatal intentions and values were higher than their postnatal behaviors and values. Parents in the intervention group exhibited higher literacy behaviors and values and greater enjoyment reading to their children than parents in the control group, though they also reported reading to their children less frequently. Parents in the intervention group had significantly higher Positive Interactive scores than controls. Overall, we found participation in newborn literacy programs positively impacted parenting behaviors and attitudes. Lower postnatal within-group scores (intentions and values versus behaviors and values) may have been the result of participants' high expectations. Given our findings, we recommend that these programs continue. PMID:26368512

The government of Canada has had a financial involvement with the nuclear industry in four areas: nuclear power development, including expenditures for research and development, prototype reactors, and regulation; uranium industry support, including the operations of Eldorado Nuclear Ltd. and the uranium stockpiling program; the financing of nuclear reactors, activities in which the federal government has acted as a banker for the sale of reactors; and heavy water production. Up to 1978-79 total federal expenditures of around $3.4 billion in current collars had been invested. Of this amount, about 56 percent was associated with nuclear power development, 2 percent with uranium industry support, 22 percent with heavy water, and 22 percent with financing reactor sales

The major irradiation facility at Chalk River Nuclear Laboratories (CRNL) is the NRU research reactor. Both unvented and vented capsule experiments on candidate blanket ceramics can be performed. In the unvented tests, tritium release data (HT-to-HTO ratio, tritium retention) are obtained by post-irradiation heating of the breeder ceramic in the presence of a sweep gas. Four tests have been completed on Li 2O and LiAlO 2. Effects of sweep gas composition, extraction vessel material and ceramic properties have been determined. Two unvented irradiations under the BEATRIX international breeder exchange program have been completed; analysis is underway. The vented tests involve long-term irradiation of candidate blanket materials. CRITIC-I, scheduled for mid-1986 under BEATRIX, will examine ANL-fabricated Li 2O in a six-month irradiation at 700-1200 K, varying sweep gas composition, with on-line HT/HTO measurement. Additionally, accelerator simulation techniques are available, using 70 kV and 2.0 MV mass separators, a 2.5 MV Van de Graaff accelerator and a tandem accelerator super-conducting cyclotron, the latter allowing irradiation with protons, deuterons or helium at 18-20 MeV.

Full Text Available Endemic tuberculosis (TB was almost certainly present in Canadian aboriginal people (aboriginal Canadians denotes status Indians, Inuit, nonstatus Indians and metis as reported by Statistics Canada before the Old World traders arrived. However, the social changes that resulted from contact with these traders created the conditions that converted endemic TB into epidemic TB. The incidence of TB varied inversely with the time interval from this cultural collision, which began on the east coast in the 16th century and ended in the Northern Territories in the 20th century. This relatively recent epidemic explains why the disease is more frequent in aboriginal children than in Canadian-born nonaboriginal people. Treatment plans must account for the socioeconomic conditions and cultural characteristics of the aboriginal people, especially healing models and language. Prevention includes bacillus Calmette-Guerin vaccination and chemoprophylaxis, and must account for community conditions, such as rates of suicide, which have exceeded the rate of TB. The control of TB requires a centralized program with specifically directed funding. It must include a program that works in partnership with aboriginal communities.

Despite of the steady decrease of surgical site infection (SSI) over the last two decades, the incidence of SSI after hip and knee arthroplasty has recently surged. This may be explained by technical changes that may result in an increased risk of SSI, such as the broad implementation of fast track programs, and/or early interventions on suspected SSI. By definition, early intervention may lead to a higher SSI score, even in the absence of a true SSI. In any case, the reverse trend of SSI war...
Understanding the performance and impact of public knowledge translation funding interventions: Protocol for an evaluation of Canadian Institutes of Health Research knowledge translation funding programs
McLean Robert K D
Full Text Available Abstract Background The Canadian Institutes of Health Research (CIHR has defined knowledge translation (KT as a dynamic and iterative process that includes the synthesis, dissemination, exchange, and ethically-sound application of knowledge to improve the health of Canadians, provide more effective health services and products, and strengthen the healthcare system. CIHR, the national health research funding agency in Canada, has undertaken to advance this concept through direct research funding opportunities in KT. Because CIHR is recognized within Canada and internationally for leading and funding the advancement of KT science and practice, it is essential and timely to evaluate this intervention, and specifically, these funding opportunities. Design The study will employ a novel method of participatory, utilization-focused evaluation inspired by the principles of integrated KT. It will use a mixed methods approach, drawing on both quantitative and qualitative data, and will elicit participation from CIHR funded researchers, knowledge users, KT experts, as well as other health research funding agencies. Lines of inquiry will include an international environmental scan, document/data reviews, in-depth interviews, targeted surveys, case studies, and an expert review panel. The study will investigate how efficiently and effectively the CIHR model of KT funding programs operates, what immediate outcomes these funding mechanisms have produced, and what impact these programs have had on the broader state of health research, health research uptake, and health improvement. Discussion The protocol and results of this evaluation will be of interest to those engaged in the theory, practice, and evaluation of KT. The dissemination of the study protocol and results to both practitioners and theorists will help to fill a gap in knowledge in three areas: the role of a public research funding agency in facilitating KT, the outcomes and impacts KT funding
Water samples were analyzed for total U, Ra-226, Cs-137, Sb-125 and tritium. Levels are generally low, and no time trends were discernible during the monitoring period. Temporal variations among the quarterly analyses are mostly insignificant. Except for total U at certain locations, all other radionuclide levels were much below the 'target concentration' guidelines for Canadian drinking water. The main contribution to the radiological dose commitment was from total U and Ra-226. Contributions from individual radionuclides to cumulative dose were in the order: total U > Ra-226 > tritium > Cs-137 > Sb-125. The limited sediment data suggest that the nuclear facilities along the Ottawa River have increased the levels of Cs-137 and Co-60 but have not affected those of Pb-210 and Ra-226. Total U and Ra-226 activities data suggest disequilibrium; the levels of total U in water were much higher than those of Ra-226. Concentrations of the two radionuclides, however, were positively correlated for most surface waters
Full text: Canada operates a publicly funded health care system in which 70% of health care costs are paid by some level of government. Radiotherapy, indeed most cancer management, falls within the publicly funded realm of Canada's health care system. National legislation (the Canada Health Act) guarantees access to cancer services for all Canadians. However, the financial responsibility for these services is borne by the provinces. Most Canadian provinces manage the cancer management problem through central cancer agencies. In the past few decades, these provincial cancer agencies have formed the Canadian Association of Provincial Cancer Agencies (CAPCA). This association has adopted a broad mandate for cancer management in Canada (see www.capca.ca). Included in this mandate is the adoption of standards and guidelines for all aspects of cancer control. The complexity of radiation therapy has long underscored the need for cooperation at the international and national levels in defining programmes and standards. In recent decades formal quality assurance programme recommendations have emerged in the United States, Europe and Great Britain. When defining quality assurance programs, Canadian radiation treatment centres have referenced U.S. and other program standards since they have been available. Recently, under the leadership of the Canadian Association of Provincial Cancer Agencies (CAPCA), Canadian national quality assurance program recommendations are emerging. A CAPCA sponsored project to harmonize Canadian quality assurance processes has resulted in a draft document entitled 'Standards for Quality Assurance at Canadian Radiation Treatment Centres'. This document provides recommendations for the broad framework of radiation therapy quality assurance programs. In addition, detailed work is currently underway regarding equipment quality control procedures. This paper explores the historical and political landscape in which the quality assurance problem has

In this paper, we present the results of a study of the impact of Canadian carbon stabilization programs on exports of natural gas to the United States. This work was based on a study conducted for the US Environmental Protection Agency. The Gas Systems Analysis model (GSAM), developed by ICF Consulting for the US Department of Energy, was used to gauge the overall impact of the stabilization programs on the North American natural gas market. GSAM is an intertemporal, spatial price equilibrium (SPE) type model of the North American natural gas system. Salient features of this model include characterization of over 17 000 gas production reservoirs with explicit reservoir-level geologic and economic information used to build up the supply side of the market. On the demand side, four sectors, residential, commercial, industrial and electric power generation, are characterized in the model. Lastly, both above and below ground storage facilities as well as a comprehensive pipeline network are used with the supply and demand side characterizations to arrive at estimates of market equilibrium prices and quantities and flows. 35 refs

The Gunston polycentric knee arthroplasty, first designed and performed by Frank Gunston in 1971, is the first prosthesis considering the natural knee biomechanics. Although the polycentric knee arthroplasty showed encouraging results to relieve pain and to preserve the preoperative range of motion and joint instability, the improvements in prosthesis design and arthroplasty technology rapidly made the polycentric knee prosthesis obsolete. Herein, we report a 58-year old male patient who had revision of the Gunston polycentric knee arthroplasty with total knee arthroplasty performed 32 years after the initial operation. PMID:21343693
This paper describes the design and construction of new Performance Testing programme that was implemented in Canada in 2008. The Canadian Regulator (Canadian Nuclear Safety Commission - CNSC) had determined that their licensees, in addition to the existing In Vivo and In Vitro performance tests, needed to demonstrate their ability in interpreting bioassay results. The program is administered by the Canadian National Calibration Reference Centre for Bioassay and In Vivo Monitoring (NCRC). Currently the NCRC carries out the performance testing for the In Vitro and In Vivo. At time of writing, the first round has not been completed and the pass/fail criteria have not been determined.

Eating disorder clinics across Canada place heavy reliance on group-based programming. However, little work has examined whether this modality of treatment is well-received by patients and results in clinical improvements. The purpose of this pilot study was to evaluate patient satisfaction and outcomes for group-based programming offered through an adult eating disorders clinic. Participants were 81 adults who met DSM-5 criteria for an eating disorder and participated in the study as part of the clinic's program evaluation. Participants received medical monitoring, psychiatric follow-up, adjunct nutrition and pre-psychological treatment, and participated in the clinic's core cognitive behavioural therapy (CBT) group. Demographic information and weight were collected at intake. Participants also completed pre- and post-group programming measures of life satisfaction, depressive and anxiety symptoms, psychological symptoms of the eating disorder, and satisfaction with the programming. Participants' experienced a significant increase in satisfaction with life, and decreases in depressive symptoms and psychological symptoms of the eating disorder post-group. Adults endorsed feeling fairly satisfied with the group-based services provided. Results draw attention to the importance of program evaluation as an integral component of an adult outpatient eating disorder clinic by providing a voice for patients' views of the services received and program outcomes.

Spectral induced polarization (SIP) parameters can be extracted from field or laboratory complex resistivity measurements, and even airborne or ground frequency domain electromagnetic data. With the growing interest in application of complex resistivity measurements to environmental and mineral exploration problems, there is a need for accurate and easy-to-use inversion tools to estimate SIP parameters. These parameters, which often include chargeability and relaxation time may then be studied and related to other rock attributes such as porosity or metallic grain content, in the case of mineral exploration. We present an open source program, available both as a standalone application or Python module, to estimate SIP parameters using Markov-chain Monte Carlo (MCMC) sampling. The Python language is a high level, open source language that is now widely used in scientific computing. Our program allows the user to choose between the more common Cole-Cole (Pelton), Dias, or Debye decomposition models. Simple circuits composed of resistances and constant phase elements may also be used to represent SIP data. Initial guesses are required when using more classic inversion techniques such as the least-squares formulation, and wrong estimates are often the cause of bad curve fitting. In stochastic optimization using MCMC, the effect of the starting values disappears as the simulation proceeds. Our program is then optimized to do batch inversion over large data sets with as little user-interaction as possible. Additionally, the Bayesian formulation allows the user to do quality control by fully propagating the measurement errors in the inversion process, providing an estimation of the SIP parameters uncertainty. This information is valuable when trying to relate chargeability or relaxation time to other physical properties. We test the inversion program on complex resistivity measurements of 12 core samples from the world-class gold deposit of Canadian Malartic. Results show

The Canadian Fusion Fuels Technology Project was launched in 1982 to coordinate Canada's provision of fusion fuels technology to international fusion power development programs. The project has a mandate to extend and adapt existing Canadian tritium technologies for use in international fusion power development programs. 1985-86 represents the fourth year of the first five-year term of the Canadian Fusion Fuels Technology Project (CFFTP). This reporting period coincides with an increasing trend in global fusion R and D to direct more effort towards the management of tritium. This has resulted in an increased linking of CFFTP activities and objectives with those of facilities abroad. In this way there has been a continuing achievement resulting from CFFTP efforts to have cooperative R and D and service activities with organizations abroad. All of this is aided by the cooperative international atmosphere within the fusion community. This report summarizes our past year and provides some highlights of the upcoming year 1986/87, which is the final year of the first five-year phase of the program. AECL (representing the Federal Government), the Ministry of Energy (representing Ontario) and Ontario Hydro, have given formal indication of their intent to continue with a second five-year program. Plans for the second phase will continue to emphasize tritium technology and remote handling

This report is the eleventh in a series of semi-annual status reports on the research and development program for the safe management and disposal of Canada's nuclear fuel waste. it describes progress achieved in the three major subprograms, engineered systems, natural systems and performance assessment, from 1991 April 1 to September 30. It also gives a brief description of the activities being carried out in preparation for the public and governmental review of the disposal concept. Since 1987, this program has been jointly funded by AECL and Ontario Hydro under the auspices of the CANDU Owners Group (COG).
The hip joint is the largest joint in the human body and consequently, its evaluation by diagnostic imaging is highly important. This includes imaging of hip joint arthroplasty, which is used to avoid joint immobility following a wide spectrum of diseases, such as end-stage degenerative disease, avascular necrosis of the femoral head or post-traumatic fractures. Conventional radiography is still the standard imaging modality for the evaluation of hip arthroplasty both directly following surgery and for periodical follow-up. In the majority of cases conventional radiography enables adequate assessment of early and late complications that can arise following hip arthroplasty, such as loosening, prosthetic or periprosthetic fracture, luxation, infection and soft tissue calcification. If the diagnosis cannot be established by means of radiography, advanced imaging methods such as computed tomography (CT) and magnetic resonance imaging (MRI), with or without injection of contrast media, may provide additional information. This is particularly true for the depiction of inflammatory processes. Regardless of the imaging modality used patients' clinical symptoms must also be taken into account in order to establish the correct diagnosis. (orig.)

Background: Depression is frequently unrecognized and undertreated. Therefore, there is a need to increase the knowledge and skills of primary care physicians regarding the diagnosis and treatment of depression. The aim of this study was to provide, and evaluate the impact of, a brief educational program with a number of practice tools and resources in order to improve family physicians' knowledge, diagnosis, and treatment of depression.
Six years ago the federal government accepted its responsibility for the radioactive waste that has resulted from the six decades of nuclear research and development conducted by Atomic Energy of Canada Limited and its predecessor operator of the Chalk River Laboratories (CRL) the National Research Council (1944 - 1952). Nuclear research and development and, particularly, reactor operation at CRL has resulted in outdated and unused research facilities and buildings and a wide variety of buried and stored radioactive waste. In 2006 the federal government established the Nuclear Legacy Liabilities Program (NLLP) with an initial funding of $520 million. The mandate of the NLLP is to deal with the radioactive waste arising from the nuclear research and development program of AECL and also prototype reactors in which it was involved. The timeline for the NLLP extends several decades into the future. The NLLP is implemented through a partnership of Natural Resources Canada (NRCan) and AECL. NRCan is responsible for policy direction and oversight, while AECL is responsible for program implementation and all licences, facilities and lands. About 70 percent of the liabilities from AECL activities are at CRL. Other sites that will be restored under the NLLP are: the Whiteshell Laboratories and Underground Research Laboratory in Manitoba; NPD and Douglas Point reactors in Ontario; and the Gentilly 1 reactor in Quebec.

Literacy in the Science Classroom Project was a three-year professional development (PD) program supporting minority-language secondary teachers' use of effective language-based instructional strategies for teaching science. Our primary objective was to determine how teacher beliefs and practices changed over time and how these were enacted in different classrooms. We also wanted to identify the challenges and enablers to implementing these literacy strategies and practices at the classroom, school, and district levels. Data collection involved both qualitative and quantitative methodologies: student questionnaires; interviews with teachers, principals, and mentor; and focus groups with students. The findings suggest that the program had an impact on beliefs and practices commensurate with the workshop participation of individual teachers. These language-enhanced teacher practices also had a positive impact on the use of talking, reading and writing by students in the science classroom. Finally, continuing PD support may be needed in certain jurisdictions for strengthening minority-language programs given the high teacher mobility in content-area classrooms evident in this study.
A federal government environmental assessment review of the disposal concept developed under the Canadian Nuclear Fuel Waste Management Program is currently underway. The Canadian concept is, simply stated, the placement of used fuel (or fuel waste) in long-lived containers at a depth between 500 m and 1000 m in plutonic rock of the Canadian Shield. Atomic Energy of Canada Limited submitted an Environmental Impact Statement in 1994 and the public hearing aspect of the concept review is in its final phase. A unique aspect of the Canadian situation is that government has stipulated that site selection can not commence until the concept has been approved. Hence, the safety and acceptability of the concept is being reviewed in the context of a generic site. Some comments and lessons learned to date related to the review process are discussed. (author)

Precipitation chemistry and depth measurements obtained by the Canadian Air and Precipitation Monitoring Network (CAPMoN) and the US National Atmospheric Deposition Program/National Trends Network (NADP/NTN) were compared for the 10-year period 1995–2004. Colocated sets of CAPMoN and NADP instrumentation, consisting of precipitation collectors and rain gages, were operated simultaneously per standard protocols for each network at Sutton, Ontario and Frelighsburg, Ontario, Canada and at State College, PA, USA. CAPMoN samples were collected daily, and NADP samples were collected weekly, and samples were analyzed exclusively by each network’s laboratory for pH, H + , Ca2+ , Mg2+ , Na + , K + , NH+4 , Cl − , NO−3 , and SO2−4 . Weekly and annual precipitation-weighted mean concentrations for each network were compared. This study is a follow-up to an earlier internetwork comparison for the period 1986–1993, published by Alain Sirois, Robert Vet, and Dennis Lamb in 2000. Median weekly internetwork differences for 1995–2004 data were the same to slightly lower than for data for the previous study period (1986–1993) for all analytes except NO−3 , SO2−4 , and sample depth. A 1994 NADP sampling protocol change and a 1998 change in the types of filters used to process NADP samples reversed the previously identified negative bias in NADP data for hydrogen-ion and sodium concentrations. Statistically significant biases (α = 0.10) for sodium and hydrogen-ion concentrations observed in the 1986–1993 data were not significant for 1995–2004. Weekly CAPMoN measurements generally are higher than weekly NADP measurements due to differences in sample filtration and field instrumentation, not sample evaporation, contamination, or analytical laboratory differences.
Purpose: Statistics from the Canadian post-MD education registry show that numbers of Canadian radiation oncology (RO) trainees have risen from 62 in 1999 to approximately 150 per year between 2003 and 2009, contributing to the current perceived downturn in employment opportunities for radiation oncologists in Canada. When last surveyed in 2003, Canadian RO residents identified job availability as their main concern. Our objective was to survey current Canadian RO residents on their training and career plans. Methods and Materials: Trainees from the 13 Canadian residency programs using the national matching service were sought. Potential respondents were identified through individual program directors or chief resident and were e-mailed a secure link to an online survey. Descriptive statistics were used to report responses. Results: The eligible response rate was 53% (83/156). Similar to the 2003 survey, respondents generally expressed high satisfaction with their programs and specialty. The most frequently expressed perceived weakness in their training differed from 2003, with 46.5% of current respondents feeling unprepared to enter the job market. 72% plan on pursuing a postresidency fellowship. Most respondents intend to practice in Canada. Fewer than 20% of respondents believe that there is a strong demand for radiation oncologists in Canada. Conclusions: Respondents to the current survey expressed significant satisfaction with their career choice and training program. However, differences exist compared with the 2003 survey, including the current perceived lack of demand for radiation oncologists in Canada.

Full Text Available There is limited in-depth research focusing on how the state exerts its power and influence through immigration laws, policies and practices in structuring the relations of labour and capital in a manner that reflects capitalist interests. Therefore, the purpose of this paper is to explore the role of the state in fostering capitalist accumulation, using the Seasonal Agricultural Worker Program (SAWP as a case study, and to consider the policy implications of this program. This paper addresses the following questions: What shapes and reproduces labour-capital relations with reference to SAWP? What are the repercussions of these relations, particularly on the international migrant workers? What should be the role of the state and law in transforming these relations? The paper draws on a constellation of insights from neoliberal globalization, segmentation of labour theory, and a conceptual overview of the role of the state in regulating labour-capital relations to illuminate the discussions. This paper helps broaden our current understanding of how the state facilitates capitalist accumulation in the agricultural sector in Canada through immigration policies and practices with reference to the SAWP. The paper therefore makes a contribution to the theoretical debates on the role of the state in the facilitation of capitalist accumulation in agriculture. Il y a peu de recherches approfondies axées sur l'exercice du pouvoir et sur l'influence des lois en matière d'immigration élaborées par l'État, ainsi que sur les politiques et les pratiques de structuration des relations entre les travailleurs et le capital, d'une manière qui reflète les intérêts capitalistes. Par conséquent, l'objectif de ce document est d'explorer le rôle de l'État qui vise à favoriser l'accumulation capitaliste, à l'aide du Programme des travailleurs agricoles saisonniers (PTAS comme une étude de cas, et d'examiner les conséquences de ce programme.

Full Text Available In Klippel–Trenaunay syndrome, vascular malformations are not only in skin and superficial soft tissues but also in deep tissues like muscles bones and joints. It is well documemted that these recurrent intraarticular bleeds can cause early arthritis and joint pain. Performing arthroplasty in such patients is difficult and fraught with complications. We describe such a case where navigated total knee arthroplasty was performed with success to avoid the problems of intra medullary alignment used in the presence of intra medullary vascular malformations. We also suggest certain measures when knee arthroplasty is considered in such patients.
With increased life expectancy in industrialised countries, improvement of implant design and operative technique, arthroplasty has become a routine procedure. The hip and knee joints are treated by arthroplasty most frequently. Nowadays joint replacement can be performed in many other joints. Radiologic imaging is an important tool for evaluation of the operative results and for detection of early and late complications. In the following article we describe the relevance of different imaging modalities as well as their systematic application in patients with joint arthroplasty. (orig.)

The study consists of 208 elbow arthroplasties performed on rheumatoid arthritic patients. A straight resection of the joint was used in 53 cases and a modified Hass arthroplasty with skin interposition in 155 cases. The average postoperative range of motion in these groups was 100 degrees and 96 degrees respectively. Postoperatively the joint was painless in 81 and 67% of the elbows respectively. The Hass arthroplasty gave a better stability and extension power. The most common complications were paresthesias in the region of the ulnar nerve and bone resorption in the region of the ulnar nerve and bone resorption in the region of the olecranon fossa.

With advances in implant technology, total ankle arthroplasty (TAA) has become an increasingly popular alternative to arthrodesis for the management of end-stage ankle arthritis. However, reports in the literature do not focus on the imaging features of TAA. Through a literature review, we demonstrate basic design features of the current ankle arthroplasty system, and the normal and abnormal postoperative imaging features associated with such devices. Pre- and postoperative evaluations of ankle arthroplasty mainly include radiography; in addition, computed tomography and magnetic resonance imaging provide further characterization of imaging abnormalities. Familiarization with multimodal imaging features of frequent procedural complications at various postoperative intervals is important in radiological practice. PMID:27134529

Surveillance of youth tobacco use can help inform prevention programs by monitoring trends in risk behaviors. We examined the prevalence of bidi and hookah use and factors associated with their use among Canadian youth by using data from the 2010–2011 Youth Smoking Survey (YSS). Methods We analyzed YSS data from 28,416 studen...
This booklet is designed to explain salient aspects of the Ozone Annex, negotiated and signed recently by Canada and the United States, in a joint effort to improve air quality in North America. By significantly reducing the transboundary flows of air pollutants that cause smog, the Ozone Annex will benefit some 16 million people in central and eastern Canada and provide an example for a future round of negotiations to address concerns of the millions of Canadians and Americans who live in the border area between British Columbia and Washington State. The brochure provide summaries of the Canadian and American commitments, focusing on transportation, monitoring and reporting. The Ozone Annex complements other air quality initiatives by the Government of Canada enacted under the Environmental Protection Act, 1999. These measures include regulations to reduce sulphur content to 30 parts per million by Jan 1, 2005; proposing to restrict toxic particulate matter (PM) to less than 10 microns; establishing daily smog forecasts in the Maritimes and committing to a national program built upon existing smog advisories and forecasts in Quebec, Ontario and British Columbia; and investing in more clean air research through the newly created Canadian Foundation for Climate and Atmospheric Sciences

Background and purpose We have previously reported that the first 10 years of hip arthroplasty in Lithuania resulted in a higher cumulative revision rate than that observed in Sweden. We thus compared the corresponding results after introduaction of total knee replacement in Lithuania. Methods The 10-year revision rate for the first 595 primary ScanKnee arthroplasties inserted in Klaipeda, Lithuania, was compared to that for the first 1,280 ScanKnee primary arthroplasties inserted in Sweden. As in the hip replacement study, only patients with osteoarthritis (OA) were included. Primary knee arthroplasties without patellar resurfacing were included, and the endpoint was revision for any reason other than addition of a patellar component. Results We found that the cumulative revision rate was not statistically significantly different between the groups. The revision pattern was different, however, and we observed 24 isolated patellar component additions in Sweden, but none in Klaipeda. Interpretation Contrary to the results of our previous hip arthroplasty study, the cumulative revision rate after total knee arthroplasty was similar in the two groups. This suggests that compared to hip arthroplasty, the outcome of total knee arthroplasty was less dependent on surgical experience. The large difference regarding isolated patellar component additions may be explained by long-term accumulation of severe OA cases in Lithuania. To patients subject to a newly introduced surgical treatment offering great improvement in quality of life, patellofemoral pain may be a minor problem. Furthermore, patellar problems may not have seemed particularly relevant for the surgeons, considering the disability of other patients waiting to be treated. PMID:19297790

The outcomes of total shoulder arthroplasty (TSA) for painful arthritis of the glenohumeral joint are excellent with significant improvement in pain and function. Increased use of total shoulder arthroplasty over the past decade has led to identification of common complications. Although the complication rate is low, accurate and timely diagnosis, appropriate management, and implementation of methods for prevention are critical to a successful long-term outcome. The most common complications ...

Polyethylene (PE) has been used extensively in knee arthroplasty since the mid 20th century. Progress in material manufacturing and processing has led to newer polyethylenes over last few decades with different material properties. It has been established that PE wear in knee arthroplasty causes particle induced osteolysis which is the main reason for late failure and requires revision surgery. Although there are various causes of wear, the properties of PE have long been a matter of investig...

Bilingualism in French and English is a much-to-be hoped for common and shared characteristic of Canadian citizenship—even though to date the effect of forty years of the Official Languages Act has been most marked in government services and among various Canadian elites. Although it is important that Canada hold onto a goal of the widest possible bilingualism,more modest objectives are outlined for the years immediately ahead.

BACKGROUND: Total elbow arthroplasties (TEAs) are traditionally grouped into linked and unlinked design. The aim was to analyze the difference in clinical outcomes after TEA based on implant design and indication for surgery and to evaluate primary and revision TEAs. METHODS: A total of 167 TEAs...... (126 primary and 41 revision TEAs) in 141 patients were evaluated with patient-reported outcome measure by the Oxford Elbow Score (OES) and clinically assessed with the Mayo Elbow Performance Score (MEPS), range of motion (ROM), and standard radiographs. RESULTS: The mean follow-up was 10.5 years for...... primary and 7.5 years for revision TEAs. There was no difference in OES or MEPS between linked and unlinked primary TEAs. The OES score in the social-psychological domain was significantly lower in TEAs performed due to fracture (67) compared with rheumatoid arthritis (81; P = .025). ROM in extension...

For the past three years, during a period of high sun spot numbers, propagation measurements were made on the reception of VLF signals in the Canadian Arctic. Between Aug. and Dec. 1989, the received signal strengths were measured on the Canadian Coast Guard icebreaker, John A. MacDonald in the Eastern Canadian Arctic. Between Jul. 1991 and Jun. 1992, the received signal strengths were measured at Nanisivik, Baffin Island. The purposes of this work were to check the accuracy and estimate variances of the Naval Ocean Systems Center's (NOSC) Long Wave Propagation Capability (LWPC) predictions in the Canadian Arctic and to gather ionospheric storm data. In addition, the NOSC data taken at Fort Smith and our data at Nanisivik were used to test the newly developed Longwave Noise Prediction (LNP) program and the CCIR noise predictions, at 21.4 and 24.0 kHz. The results of the work presented and discussed in this paper show that in general the LWPC predicts accurate values of received signal strength in the Canadian Arctic with standard deviations of 1 to 2 dB over several months. Ionospheric storms can gauge the received signal strengths to decrease some 10 dB for a period of several hours or days. However, the effects of these storms are highly dependent on the propagation path. Finally the new LNP atmospheric noise model predicts lower values of noise in the Arctic than the CCIR model and our limited measurements tend to support these lower values.

We survey the present landscape in submillimetre astronomy for Canada and describe a plan for continued engagement in observational facilities to ~2020. Building on Canada's decadal Long Range Plan process, we emphasize that continued involvement in a large, single-dish facility is crucial given Canada's substantial investment in ALMA and numerous PI-led submillimetre experiments. In particular, we recommend: i) an extension of Canadian participation in the JCMT until at least the unique JCMT Legacy Survey program is able to realize the full scientific potential provided by the world-leading SCUBA-2 instrument; and ii) involvement of the entire Canadian community in CCAT, with a large enough share in the partnership for Canadian astronomers to participate at all levels of the facility. We further recommend continued participation in ALMA development, involvement in many focused PI-led submillimetre experiments, and partnership in SPICA.

The International Society of Arthroplasty Registries (ISAR) Steering Committee established the Patient-Reported Outcome Measures (PROMs) Working Group to convene, evaluate, and advise on best practices in the selection, administration, and interpretation of PROMs and to support the adoption and use of PROMs for hip and knee arthroplasty in registries worldwide. The 2 main types of PROMs include generic (general health) PROMs, which provide a measure of general health for any health state, and specific PROMs, which focus on specific symptoms, diseases, organs, body regions, or body functions. The establishment of a PROM instrument requires the fulfillment of methodological standards and rigorous testing to ensure that it is valid, reliable, responsive, and acceptable to the intended population. A survey of the 41 ISAR member registries showed that 8 registries administered a PROMs program that covered all elective hip or knee arthroplasty patients and 6 registries collected PROMs for sample populations; 1 other registry had planned but had not started collection of PROMs. The most common generic instruments used were the EuroQol 5 dimension health outcome survey (EQ-5D) and the Short Form 12 health survey (SF-12) or the similar Veterans RAND 12-item health survey (VR-12). The most common specific PROMs were the Hip disability and Osteoarthritis Outcome Score (HOOS), the Knee injury and Osteoarthritis Outcome Score (KOOS), the Oxford Hip Score (OHS), the Oxford Knee Score (OKS), the Western Ontario and McMaster Universities Arthritis Index (WOMAC), and the University of California at Los Angeles Activity Score (UCLA).

Purpose: Radiation oncology's popularity as a career in Canada has surged in the past 5 years. Consequently, resident numbers in Canadian radiation oncology residencies are at all-time highs. This study aimed to survey Canadian radiation oncology residents about their opinions of their specialty and training experiences. Methods and Materials: Residents of Canadian radiation oncology residencies that enroll trainees through the Canadian Resident Matching Service were identified from a national database. Residents were mailed an anonymous survey. Results: Eight of 101 (7.9%) potential respondents were foreign funded. Fifty-two of 101 (51.5%) residents responded. A strong record of graduating its residents was the most important factor residents considered when choosing programs. Satisfaction with their program was expressed by 92.3% of respondents, and 94.3% expressed satisfaction with their specialty. Respondents planning to practice in Canada totaled 80.8%, and 76.9% plan to have academic careers. Respondents identified job availability and receiving adequate teaching from preceptors during residency as their most important concerns. Conclusions: Though most respondents are satisfied with their programs and specialty, job availability and adequate teaching are concerns. In the future, limited time and resources and the continued popularity of radiation oncology as a career will magnify the challenge of training competent radiation oncologists in Canada

The purpose of this study is to describe complications affecting the patella in patients with total or partial knee arthroplasty. We respectively analysed plain-film radiographs, as well as ultrasound images when acquired, in a consecutive series of 1272 patients. The mean interval from knee replacement to patellar complications was 5 years and 7 months (range, 5 months to 14 years). The complications described include fracture, instability, dislocation or luxation, necrosis of the patella, infection of the patella, erosion of the patella, patellar impingement on the prosthesis and patellar or quadricipital tendon tear. We discuss the pathological imaging findings in the patella and their differential diagnosis after knee arthroplasty. Patellar complications after knee arthroplasty are uncommon but often potentially serious.

An overview is provided of the global oil and gas market, industry, reserves, and factors affecting the market's instability. The Canadian oil and gas sector is then profiled. Research and technology strategies in the global oil and gas sector are reviewed in the areas of increasing supplies, improving energy efficiency, developing alternative energy sources, mitigating environmental impacts, and developing new products and services. Finally, research, development, and technology strategies in the Canadian oil and gas sector are evaluated, including private sector research and development (R ampersand D) government support programs, and technology opportunities for the industry in refining, in-situ oil sands production, ultrasour gas production, and downstream gas processing. Total R ampersand D spending by the Canadian oil and gas industry is only ca $300 million/y, with most small to medium-size companies doing little R ampersand D. Since 64% of the Canadian petroleum sector is foreign owned, decisions to increase R ampersand D investment must involve foreign decision makers. The focus of Canadian R ampersand D tends to be upstream-oriented and on the exploitation of unconventional resources, notably the oil sands. Opportunities also exist in downstream R ampersand D such as alternative fuels and energy systems management. Since upstream R ampersand D is a risky long-term proposition, the roles of resource companies, refiners, research institutions, and Canadian and overseas governments must be defined to ensure that research efforts are coordinated and costs are shared equitably. This will likely require a concerted action plan specifying technology goals, memoranda of understanding between all the players, and reasonable accountability levels. 19 refs., 10 tabs
Full Text Available Arthritis is a disease that acts irreversibly on joint surfaces with significant consequences especially in the third quarter of life. About 7% of our population is affected by arthritis localized at a certain level and stage of development, and this percentage is expected to reach a much higher value in future years. Aim: The aim of this study is to propose a rehabilitation program for functional recovery after total hip arthroplasty and a set of recommendations for post surgery period. Material and methods: There were included 13 subjects (10 female and 3 male aged between 51 and 78 years old, ready for total hip arthroplasty with uncemented prosthesis. The subjects were selected in Orthopaedics and Traumatology department of Military Clinical Emergency Hospital ”Dr. Victor Popescu” Timisoara. The evaluations regarding programs’ efficiency were made using 3 questionnaires (Oxford Hip Score, Harris Hip Score, Outcome Hip Score and goniometry. The subjects were tested initially before the surgery and 3 times after (at one month, at 3 months and at 6 months. Results: The results showed a remarcable increase for the scores of majority, in both questionnaire and goniometry values. Conclusions: functional rehabilitation exercises proved to be particularly important in regaining independence, control of the prosthetic leg, pain reduction and functional and social reintegration.

A wide ranging discussion about the factors that have influenced oil and natural gas prices, the differences of the Canadian market from international markets, the differences between eastern and western Canadian markets, and shareholders' perspectives on recent commodity price developments was presented. Developments in the OPEC countries were reviewed, noting that current OPEC production of 25 mmbbls is about 60 per cent higher than it was in 1985. It is expected that OPEC countries will continue to expand capacity to meet expected demand growth and the continuing need created by the UN embargo on Iraqi oil sales. Demand for natural gas is also likely to continue to rise especially in view of the deregulation of the electricity industry where natural gas may well become the favored fuel for incremental thermal generation capacity. Prices of both crude oil and natural gas are expected to hold owing to unusually low storage levels of both fuels. The inadequacy of infrastructure, particularly pipeline capacity as a key factor in the Canadian market was noted, along with the dynamic that will emerge in the next several years that may have potential consequences for Canadian production - namely the reversal of the Sarnia to Montreal pipeline. With regard to shareholders' expectations the main issues are (1) whether international markets reach back to the wellhead, hence the producer's positioning with respect to transportation capacity and contract portfolios, and (2) whether the proceeds from increased prices are invested in projects that are yielding more than the cost of capital. 28 figs

Full Text Available Arthroplasty is used when there is irreversible damage to the articular cartilage of the knee. It involves implanting a bicompartimental (femoral and tibial components or a tricompartimental (femoral, tibial and patellar components prosthesis. It is a very invasive and costly operation, so our objective was to evaluate the necessity of the patellar component.

Full Text Available Scientific background: Man-made joints (joint endoprostheses, including knee endoprostheses, are used in some irreversible diseases of the human joints. The implantation of joint endoprostheses (arthroplasty is associated with an increased risk for infection. To prevent infections, different interventions without and with the use of antibiotics (hygiene procedures and antibiotic prophylaxis are used. The benefits of these interventions are not clear yet. Research questions: The presented report addresses the questions regarding the medical effectiveness, the cost-effectiveness as well as the ethical, social and legal aspects related to the use of interventions to prevent infections after knee arthroplasty. Methods: A systematic literature search is conducted in the medical electronic databases MEDLINE, EMBASE, SciSearch etc. in June 2009 and has been completed by a hand search. The analysis includes publications which describe and/or evaluate clinical data from randomized controlled trials (RCT, systematic reviews of RCT, registers of endoprostheses or databases concerning interventions to prevent infections after knee arthroplasty. The conducted literature search also aims to identify health-economic studies and publications dealing explicitly with ethical, social or legal aspects in the use of interventions to prevent infections after knee arthroplasty. The synthesis of information from different publications has been performed qualitatively. Results: The systematic literature search yields 1,030 hits. Based on the predefined inclusion and exclusion criteria a total of ten publications is included in the analysis. The presented report does not find evidence of the effectiveness of different hygiene interventions with a high evidence level. Most of the unspecific interventions are recommended on the basis of results from non-RCT, from studies for other clinical indications and/or for clinically not relevant endpoints, as well as on the basis of

Reverse total shoulder arthroplasty is becoming a common form of shoulder arthroplasty that is often performed in the setting of rotator cuff pathology. Infection is a rare complication but is more common in reverse total shoulder arthroplasty than in hemiarthroplasty or anatomic total shoulder arthroplasty. We present the case of a 69-year-old patient with a reverse total shoulder arthroplasty who presented with purulent drainage from the skin of his anterior shoulder. Computed tomography arthrogram confirmed the presence of a synovial cutaneous fistula. Synovial cutaneous fistula is a rare variant of periprosthetic infection that, to our knowledge, has not been described previously in the setting of a reverse total shoulder arthroplasty. Computed tomography arthrogram proved to be a reliable method for confirming the diagnosis and was used for operative planning to remove the hardware. PMID:27257460

The most common organisms causing prosthetic knee joint infections are staphylococci. However, arthroplasty infections with atypical microbial pathogens, such as Mycobacteria can occur. Due to the rarity of mycobacterial prosthetic joint infections, diagnosis, treatment, and management of these atypical infections represent a clinical challenge. A 71-year old female post-operative day 40 after a left total knee arthroplasty was hospitalized secondary to left knee pain and suspected arthroplasty infection. She had failed outpatient oral antimicrobial treatment for superficial stitch abscess; and outpatient IV/Oral antimicrobials for a clinical postoperative septic bursitis. Ultimately, resection arthroplasty with operative tissue acid fast bacterial cultures demonstrated growth of the Mycobacterium smegmatis group. Post-operatively, she completed a combination course of oral doxycycline and levofloxacin and successfully completed a replacement arthroplasty with clinical and microbial resolution of the infection. To our knowledge, literature review demonstrates three case of knee arthroplasty infection caused by the Mycobacterium smegmatis group. Correspondingly, optimal surgical procedures and antimicrobial management including antimicrobial selection, treatment duration are not well defined. Presently, the best treatment options consists of two step surgical management including prosthesis hardware removal followed by extended antimicrobial therapy, followed by consideration for re-implantation arthroplasty. Our case illustrates importance of considering atypical mycobacterial infections in post-operative arthroplasty infections not responding to traditional surgical manipulations and antimicrobials. For an arthroplasty infection involving the atypical Mycobacterium smegmatis group, two step arthroplasty revision, including arthroplasty resection, with a combination of oral doxycycline and levofloxacin can lead to successful infection resolution, allowing for a

On March 13 of 1991, the Prime Minister of Canada, Brian Mulroney and the President of the United States of America, George Bush, signed an Agreement on Air Quality. This agreement enshrines Principle 21 of the 1972 Stockholm Declaration which states that countries are to ensure that activities within their jurisdiction do not cause damage to the environment of another country. This agreement also includes provisions for controlling acid rain. The Agreement on Air Quality followed years of discussion between the two countries and is a significant milestone in the history of Canadian acid rain policy. This paper begins by describing Canadian acid rain policy and its evolution. The paper also outlines the Canada-United States Air Quality Agreement and the effect of the acid rain provisions on deposition in Canada. Finally, it considers the future work that must be undertaken to further resolve the acid rain problem. 8 refs., 5 figs., 1 tab
For two weeks in August, 1975 more than 140 mathematicians and other scientists gathered at the Universite de Sherbrooke. The occasion was the 15th Biennial Seminar of the Canadian Mathematical Congress, entitled Mathematics and the Life Sciences.

A primer on financing international operations by Canadian corporations was provided. Factors affecting the availability to project finance (location, political risk), the various forms of financing (debt, equity, and combinations), the main sources of government backed financing to corporations (the International Finance Corporation) (IFC), the European Bank for Reconstruction and Development (EBRD), the Asian Development Bank (ADB), the Overseas Property Insurance Corporation (OPIC), government or agency guarantees, political risk coverage, the use of offshore financial centres, and the where, when and how these various organizations operate, were reviewed. Examples of all of the above, taken from the experiences of Canadian Occidental Petroleum of Calgary in the U.S., in South America, in the Middle and Far East, and in Kazakhstan, were used as illustrations. figs

The purpose of this study was to extend previous work to detect migration of total wrist arthroplasty non-invasively, and with greater accuracy. Two human cadaverous arms, each with a cemented total wrist implant, were used in this study. In one of the arms, 1 mm tantalum balls were implanted, six in the carpal bones and five in the radius. Five CT scans of each arm were acquired, changing the position of the arm each time to mimic different positions patients might take on repeated examinations. Registration of CT volume data sets was performed using an extensively validated, 3D semi-automatic volume fusion tool in which co-homologous point pairs (landmarks) are chosen on each volume to be registered. Three sets of ten cases each were obtained by placing landmarks on 1) bone only (using only arm one), 2) tantalum implants only, and 3) bone and tantalum implants (both using only arm two). The accuracy of the match was assessed visually in 2D and 3D, and numerically by calculating the distance difference between the actual position of the transformed landmarks and their ideal position (i.e., the reference landmark positions). All cases were matched visually within one width of cortical bone and numerically within one half CT voxel (0.32 mm, p = 0.05). This method matched only the bone/arm and not the prosthetic component per se, thus making it possible to detect prosthetic movement and wear. This method was clinically used for one patient with pain. Loosening of the carpal prosthetic component was accurately detected and this was confirmed at surgery.

In August and September 2010, the U.S. Geological Survey, in cooperation with Natural Resources Canada, Geological Survey of Canada, conducted bathymetric and geophysical surveys in the Beaufort Sea and eastern Arctic Ocean aboard the U.S. Coast Guard Cutter Healy. The principal objective of this mission to the high Arctic was to acquire data in support of a delineation of the outer limits of the U.S. and Canadian Extended Continental Shelf in the Arctic Ocean, in accordance with the provisions of Article 76 of the United Nations Convention on the Law of the Sea. The Healy was accompanied by the Canadian Coast Guard icebreaker Louis S. St-Laurent. The scientific parties on board the two vessels consisted principally of staff from the U.S. Geological Survey (Healy), and the Geological Survey of Canada and the Canadian Hydrographic Service (Louis). The crew also included marine-mammal observers, Native-community observers, ice observers, and biologists conducting research of opportunity in the Arctic Ocean. Despite interruptions necessitated by three medical emergencies, the joint survey proved largely successful. The Healy collected 7,201 trackline-kilometers of swath (multibeam) bathymetry (47,663 square kilometers) and CHIRP subbottom data, with accompanying marine gravity measurements, and expendable bathythermograph data. The Louis acquired 3,673 trackline-kilometers of multichannel seismic (airgun) deep-penetration reflection data along 25 continuous profiles, as well as 34 sonobuoy refraction stations and 9,500 trackline-kilometers of single-beam bathymetry. The coordinated efforts of the two vessels resulted in seismic-reflection-profile data that were of much higher quality and continuity than if the data had been acquired with a single vessel alone. The equipment-failure rate of the seismic equipment aboard the Louis was greatly reduced when the Healy led as the ice breaker. When ice conditions proved too severe to deploy the seismic system, the Louis led
Groundwaters have been sampled from depths greater than 1000 m within the Canadian Shield. The samples were obtained from boreholes in mines and from test drilling programs carried out as part of the Canadian Nuclear Fuel Waste Management Program. At the depths explored, water is found in fractures, shear zones and similar structural features. The salinity of the water is frequently very high, with total dissolved solids often exceeding 200 g.L-1. These saline waters can be classified as Ca-Na-Cl brines. Isotopic analyses for 2H and 18O show that these fluids are not modern, local meteoric waters which dissolve salts in sedimentary, metasedimentary or metamorphic rocks. The chemical and isotopic data suggest that all saline waters analyzed to date have a similar origin. This source is not well-understood but could be highly modified Paleozoic seawater, residual metamorphic fluids, or less likely, groundwaters that have been in contact with the rocks in the Canadian Shield for millions of years. In all cases the fluids appear to have been isolated from the biosphere for geological time periods. The existence of these highly saline fluids influences the Nuclear Fuel Waste Management Program in several areas. A major concern is the corrosion resistance of the radioactive waste containers. Saline waters may also influence the buffer and backfill and vault sealing materials, the rock mass and the waste form itself, although the effects may not always be deleterious. Corrosion of underground test equipment during the geoscience research phase is also a concern

With recent increases in life expectancy in the United States, the number of nonagenarians (age 90-99 years) presenting for lower extremity joint arthroplasty (TJA) will likely rise. Utilizing the National Surgical Quality Improvement Program database, we compared 30-day outcomes of TJA between nonagenarians and controls (age <90 years). Nonagenarians had lower mean BMI, no difference in mean number of comorbidities, and shorter mean operation time. Compared to controls, nonagenarians had longer mean length-of-stay, higher readmission rate, and higher risk of postoperative adverse events. Given these findings, orthopaedic surgeons should be aware of the increased risks of TJA in nonagenarians, and should discuss these risks with potential surgical candidates during a shared decision-making process.

Full Text Available Temporomandibular joint ankylosis causes limitation in mouth opening and establishes severe deformity and asymmetry in patient’s face, especially in children. Surgery is the only treatment. This study was conducted to compare the effect of two surgical approaches, gap arthropasty and interpositional gap arthroplasty, on rate of maximum interincisal opening in temporomandibular joint ankylosis. We also evaluated the relapse rate of these two surgical approaches. A total of 48 patients were enrolled in this cross-sectional experimental study. Range of mouth opening was evaluated before and during and one year after surgery. All other related information was also recorded. Mean age of the study population was 19.5 8.9 years. Of those, 21 (41% were male and 27 (59% were female. For 26 patients (54.2% interpositional gap arthroplasty was accomplished and for 22 patients (45.8% gap arthropasty was performed. Mean range of mouth opening before and after surgery was 10.3 3.9 and 33.9 5.2 in interpositional gap arthroplasty, 8.7 4.9 and 32.1 7.8 in gap arthropasty, respectively. The results showed that the range of mouth opening significantly increases after ankylosis surgery in both surgical approaches but improvement was less in interpositional gap arthroplasty. In regards to recurrence, results of interpositional gap arthroplasty were superior to gap arthropasty.

Full Text Available Cost in shoulder surgery has taken on a new focus with passage of the Patient Protection and Affordable Care Act. As part of this law, there is a provision for Accountable Care Organizations (ACOs and the bundled payment initiative. In this model, one entity would receive a single payment for an episode of care and distribute funds to all other parties involved. Given its reproducible nature, shoulder arthroplasty is ideally situated to become a model for an episode of care. Currently, there is little research into cost in shoulder arthroplasty surgery. The current analyses do not provide surgeons with a method for determining the cost and outcomes of their interventions, which is necessary to the success of bundled payment. Surgeons are ideally positioned to become leaders in ACOs, but in order for them to do so a methodology must be developed where accurate costs and outcomes can be determined for the episode of care.

Thromboembolic events are a post-operative complication of arthroplasty surgery for up to 3 months. The incidence however, is not fully known. Some form of prophylaxis should be provided to all arthroplasty patients. Clinicians are wary of side effects, compliance profile and the associated cost. The objective of this study is to investigate practice patterns and their relevance to 3 risk groups. Ninety questionnaires were sent to orthopaedic surgeons with 3 hypothetical clinical scenarios and 10 prophylaxis regimes for thromboembolism across different risk groups. The response rate was 81\\/90 (90%). The most popular options in all 3 cases were early mobilisation, thrombo-embolism deterrant (TED) stockings and low molecular weight heparin (LMWH) (51\\/81, 62% of all cases). An inconsistent relationship exists between preferred practice and relevant guidelines. Preferred practice does not correlate with each level of risk.

Abstract Background and purpose Fast-track surgery has reduced the length of hospital stay (LOS), morbidity, and convalescence in primary hip and knee arthroplasty (TKA). We assessed whether patients undergoing revision TKA for non-septic indications might also benefit from fast-track surgery....... Methods 29 patients were operated with 30 revision arthroplasties. Median age was 67 (34-84) years. All patients followed a standardized fast-track set-up designed for primary TKA. We determined the outcome regarding LOS, morbidity, mortality, and satisfaction. Results Median LOS was 2 (1-4) days...... undergoing revision TKA for non-septic reasons may be included in fast-track protocols. Outcome appears to be similar to that of primary TKA regarding LOS, morbidity, and satisfaction. Our findings call for larger confirmatory studies and studies involving other indications (revision THA, 1-stage septic...
When the Canadian Nuclear industry launched its information program, it was found that women were less supportive of nuclear power. Reasons were difficult to pin-point and hovered around individual perceptions and misunderstandings. The basis of the Canadian Nuclear Association Public Information program lies with its target: men and women equally. The Program Takes Into Consideration The major characteristics and nuances of these two groups. Female Characteristics from Canadian Perspective are: Strong sense of generation continuity; Detail and task oriented; Nontechnical training; Strong sense of individuality (local). Patterns of behavoiur in relation to nuclear industry for women in Canada are: not prone to take risks; micro-economic approach to decisions (local); little confidence in technology; pragmatic and balanced in their choices (local). Major concerns of Canadian women are: Safety of power plants; disposal of waste; peace and environment versus growth and energy need; trustworthiness of the industry. Canadian nuclear association public information program communirations -approach covers: the right message, down to earth language, factual and real information for real choices, effective reach: spokespeople and media buy. Results of polls: show thtt women are less in favour of Nuclear energy in Canada today than men, consider NPPs less important in Meeting Canada's energy need in the years ahead; and think that Nuclear Energy is not a choice for Canada of all sources of energy available for large scale use

Hip arthroplasty has become a common and still increasing procedure for the treatment of osteoarthritis, advanced head necrosis, post-inflammatory arthritis or rheumatoid arthritis.Radiography is the most important imaging modality for monitoring the normal, asymptomatic hip arthroplasty. Radiographs are obtained at the end of a surgical treatment, to exclude complications like fracture or component misplacement. In the follow-up radiographs are used for the diagnosis of loosening and infection of the hip arthroplasty as well as soft tissue ossification. Together with the history and clinical information, the analysis of morphological findings allows to find the grade of loosening. MRI has been advocated in the diagnosis of infection, in particular in the localisation of soft tissue involvement.Imaging, especially by radiographs, is used for the evaluation of the normal and complicated follow-up of hip arthroplasty.

Objective: To explore arthroplasty in treating 3- and 4-part fractures of the proximal humerus.Methods: A total of 132 patients with proximal humeral fractures were treated in our hospital from July 1997 to February 2003. According to Neer's classification, the fractures of 45 patients (14 males and 31 females, aged 31-78 years, 56.1 years±7.8 years on an average) belonged to 3- or 4-part fractures (10 patients with 4-part fracture and 35 with 3-part comminuted fracture) and they were treated with shoulder joint arthroplasty. Unipolar prosthesis replacement of the head of humerus was made in 28 cases, while bipolar prosthesis replacement in 2 cases and total shoulder joint replacement in 15 cases. Results: During the follow-up period (range: 12-72 months, mean: 37.3 months±4.1 months), among the 45 patients who suffered from fractures of the proximal humerus and underwent arthroplasty surgery, 44 patients (97.8%) had no postoperative pain and were satisfied with the active range of motion and with the whole treatment results. And radiography showed that the prostheses were at their good position. One patient had postoperative pain because he had so narrow medullary cavity that the humeral prosthesis could not be put deeply enough and the prosthesis head was a little higher over the anatomic level. He did not have good postoperative active range of motion, either. Then he received a review surgery and got satisfied results. Temporary shoulder stiffness was observed in one patient. Manual release of these adhesions improved the shoulder function. No evidence of nonunion of the fracture segments around the humeral prosthesis stem was found. Conclusions: Shoulder arthroplasty is a dependable method to restore the comfort and function of the should joints of the patients with 3- or 4-part fractures of the proximal humerus.

One of the most important issues in the modern total hip arthroplasty (THA) is the bearing surface. Extensive research on bearing surfaces is being conducted to seek an ideal bearing surface for THA. The ideal bearing surface for THA should have superior wear characteristics and should be durable, bio-inert, cost-effective, and easy to implant. However, bearing surfaces that are currently being implemented do not completely fulfill these requirements, especially for young individuals for whom...

This report describes Canadian expertise in fusion fuels technology and remote handling. The Canadian Fusion Fuels Technology Project (CFFTP) was established and is funded by the Canadian government, the province of Ontario and Ontario Hydro to focus on the technology necessary to produce and manage the tritium and deuterium fuels to be used in fusion power reactors. Its activities are divided amongst three responsibility areas, namely, the development of blanket, first wall, reactor exhaust and fuel processing systems, the development of safe and reliable operating procedures for fusion facilities, and, finally, the application of these developments to specific projects such as tritium laboratories. CFFTP also hopes to utilize and adapt Canadian developments in an international sense, by, for instance, offering training courses to the international tritium community. Tritium management expertise is widely available in Canada because tritium is a byproduct of the routine operation of CANDU reactors. Expertise in remote handling is another byproduct of research and development of of CANDU facilities. In addition to describing the remote handling technology developed in Canada, this report contains a brief description of the Canadian tritium laboratories, storage beds and extraction plants as well as a discussion of tritium monitors and equipment developed in support of the CANDU reactor and fusion programs. Appendix A lists Canadian manufacturers of tritium equipment and Appendix B describes some of the projects performed by CFFTP for offshore clients

applications). To advance the technical readiness for the proposed lunar missions, including a lunar plant growth lander, lunar "salad machine" (i.e. small scale plant production unit) and a full scale lunar plant production system, a suite of terrestrial developments and analogue systems are proposed. As has been successfully demonstrated by past Canadian advanced life support activities, terrestrial technology transfer and the development of highly qualified personnel will serve as key outputs for Canadian advanced life support system research programs. This approach is designed to serve the Canadian greenhouse industry by developing compliance measures for mitigating environmental impact, reducing labour and energy costs as well as improving Canadian food security, safety and benefit northern/remote communities.

A study was conducted in 4 Canadian processing plants in 1995-96 to determine the prevalence of quality defects in Canadian cattle. One percent of the annual number of cattle processed in Canada were evaluated on the processing floor and 0.1% were graded in the cooler. Brands were observed on 37% and multiple brands on 6% of the cattle. Forty percent of the cattle had horns, 20% of which were scurs, 33% were stubs, 10% were tipped, and 37% were full length. Tag (mud and manure on the hide) was observed on 34% of the cattle. Bruises were found on 78% of the carcasses, 81% of which were minor in severity. Fifteen percent of the bruises were located on the round, 29% on the loin, 40% on the rib, 16% on the chuck, and 0.02% on the brisket. Grubs were observed in 0.02% of the steers, and injection sites were observed in 1.3% of whole hanging carcasses. Seventy percent of the livers were passed for human food and 14% for pet food; 16% were condemned. Approximately 71% of the liver condemnations were due to liver abscesses. Four percent of the heads, 6% of the tongues, and 0.2% of whole carcasses were condemned. The pregnancy rate in female cattle was approximately 6.7%. The average hot carcass weight was 357 kg (s = 40) in steers, 325 kg (s = 41) in heifers, 305 kg (s = 53) in cows, 388 kg (s = 62) in virgin bulls and 340 kg (s = 39) in mature bulls. The average ribeye area in all cattle was 84 cm2 (s = 12); range 29 cm2 to 128 cm2. Grade fat was highly variable and averaged 9 mm (s = 4) for steers and heifers, 6 mm (s = 6) for cows, 5 mm (s = 1) for virgin bulls, and 4 mm (s = 0.5) for mature bulls. The average lean meat yield was 59.7% in cattle (s = 3.4); range 39% to 67%. One percent of the carcasses were devoid of marbling, 1% were dark cutters, and 0.05% of the steer carcasses were staggy. Six percent of the carcasses had poor conformation, 3.7% were underfinished, and 0.7% were overfinished. Yellow fat was observed in 4% of the carcasses; 10% of carcasses were

Total elbow arthroplasty (TEA) is becoming a popular alternative to arthrodesis for patients with end-stage elbow arthrosis and comminuted distal humeral fractures. Prior outcome studies have primarily focused on surgical findings. Our purpose is to determine the radiographic outcome of TEA and to correlate with clinical symptoms such as pain. This is an IRB-approved retrospective review from 2005 to 2015 of all patients with semiconstrained TEA. All available elbow radiographs and clinical data were reviewed. Data analysis included descriptive statistics and Kaplan-Meier survival curves for radiographic and clinical survival. A total of 104 total elbow arthroplasties in 102 patients were reviewed; 75 % were in women and the mean patient age was 63.1 years. Mean radiographic follow-up was 826 days with average of four radiographs per patient. Seventy TEAs (67 %) developed radiographic complications, including heterotopic ossification (48 %), perihardware lucency (27 %), periprosthetic fracture (23 %), hardware subluxation/dislocation (7 %), polyethylene wear (3 %), and hardware fracture/dislodgement (3 %); 56 patients (55 %) developed symptoms of elbow pain or instability and 30 patients (30 %) underwent at least one reoperation. In patients with radiographic complications, 66 % developed elbow pain, compared to 19 % of patients with no radiologic complications (p = 0.001). Of the patients with radiographic complications, 39 % had at least one additional surgery compared to 0 % of patients without radiographic complications (p = 0.056). Radiographic complications are common in patients after total elbow arthroplasty. There is a strong positive association between post-operative radiographic findings and clinical outcome. Knowledge of common postoperative radiographic findings is important for the practicing radiologist. (orig.)

Unicompartmental knee arthroplasty (UKA) is an alternative procedure to high tibial osteotomy. This study assessed the procedure using computer navigation to improve implantation accuracy and presents early radiological results of a group of patients implanted with the univation UKA (B. Braun Aesculap, Tuttlingen, Germany) with navigation instrumentation and a minimally invasive approach. The authors concluded that navigated implantation of a UKA using a nonimage-based system improved radiologic accuracy implantation without significant inconvenience and minimal change in the conventional operating technique.

Full Text Available A 53-year-old woman developed a vaginal mass following an uncemented total hip arthroplasty. The mass was in direct communication with the hip through an acetabular medial wall defect after loosening of the acetabular component. The mass formation was caused simultaneously by changes secondary to polyethylene wear, a tiny delamination of the porous titanium mesh coating and a broken antirotational tab on the acetabular cup, all of which may have served as sources of metal particles. A careful evaluation of the patient′s history, symptoms, X-ray findings and computed tomography scans should always be performed to ensure accurate diagnosis.

Snapping pes syndrome is defined as a snapping sensation in the medial knee caused by pes anserinus and rarely occurs. Snapping pes syndrome after unicompartmental knee arthroplasty (UKA) has not been reported yet. We experienced two cases with this syndrome after UKA. Conservative treatment was effective in one case, while surgical excision of the gracilis tendon was necessary to relieve painful snapping in the other case. The main cause of the first case might be posteromedial overhang of the tibial tray that reached up to 5 mm. The probable cause of the second case was posteromedial overhang of the mobile bearing.

Full Text Available OBJECTIVES: To analyze muscle strength and exercise intensity adaptation to resistance training in older women with knee osteoarthritis and total knee arthroplasty. METHODS: Twenty-three community-dwelling women were divided into the following groups: older, with knee osteoarthritis and total knee arthroplasty in the contralateral limb (OKG; N= 7; older, without symptomatic osteoarthritis (OG; N= 8; and young and healthy (YG; N= 8. Muscle strength (1-repetition maximum strength test and exercise intensity progression (workload increases of 5%-10% were made whenever adaptation occurred were compared before and after 13 weeks of a twice-weekly progressive resistance-training program. RESULTS: At baseline, OKG subjects displayed lower muscle strength than those in both the OG and YG. Among OKG subjects, baseline muscle strength was lower in the osteoarthritic leg than in the total arthroplasty leg. Muscle strength improved significantly during follow-up in all groups; however, greater increases were observed in the osteoarthritic leg than in the total knee arthroplasty leg in OKG subjects. Greater increases were also seen in the osteoarthritic leg of OKG than in OG and YG. The greater muscle strength increase in the osteoarthritic leg reduced the interleg difference in muscle strength in OKG subjects, and resulted in similar posttraining muscle strength between OKG and OG in two of the three exercises analyzed. Greater exercise intensity progression was also observed in OKG subjects than in both OG and YG subjects. CONCLUSIONS: OKG subjects displayed greater relative muscle strength increases (osteoarthritic leg than subjects in the YG, and greater relative exercise intensity progression than subjects in both OG and YG. These results suggest that resistance training is an effective method to counteract the lower-extremity strength deficits reported in older women with knee osteoarthritis and total knee arthroplasty.
Purpose: To obtain, in a survey-based study, detailed information on the faculty currently responsible for teaching radiation biology courses to radiation oncology residents in the United States and Canada. Methods and Materials: In March-December 2007 a survey questionnaire was sent to faculty having primary responsibility for teaching radiation biology to residents in 93 radiation oncology residency programs in the United States and Canada. Results: The responses to this survey document the aging of the faculty who have primary responsibility for teaching radiation biology to radiation oncology residents. The survey found a dramatic decline with time in the percentage of educators whose graduate training was in radiation biology. A significant number of the educators responsible for teaching radiation biology were not fully acquainted with the radiation sciences, either through training or practical application. In addition, many were unfamiliar with some of the organizations setting policies and requirements for resident education. Freely available tools, such as the American Society for Radiation Oncology (ASTRO) Radiation and Cancer Biology Practice Examination and Study Guides, were widely used by residents and educators. Consolidation of resident courses or use of a national radiation biology review course was viewed as unlikely by most programs. Conclusions: A high priority should be given to the development of comprehensive teaching tools to assist those individuals who have responsibility for teaching radiation biology courses but who do not have an extensive background in critical areas of radiobiology related to radiation oncology. These findings also suggest a need for new graduate programs in radiobiology.
