Aquatic weeds growing in irrigation conveyance systems of the earth-lined, open-channel type retard the flow and reduce the efficiency of the systems. The aquatic weed infestations, consisting of both submerged and emergent vascular plants and algae, also reduce system capacity and may result in increased seepage and spill losses. The flow retardance effects and their impacts on the performance of the irrigation conveyance system are evaluated using a modified version of the irrigation conveyance system simulation (ICSS) model developed at the University of Calgary. Key words: aquatic plants, irrigation conveyance systems, efficiency, performance.

The Leader in Medicine (LIM) Program of the Cumming School of Medicine, University of Calgary, hosted its 7th Annual LIM Research Symposium on October 30, 2015 and participation grew once again, with a total of six oral and 99 posters presentations! Over 45 of our Faculty members also participated in the symposium. This year’s LIM Symposium theme was “Innovations in Medicine” and the invited guest speaker was our own Dr. Breanne Everett (MD/MBA). She completed her residency in plastic surgery at University of Calgary and holds both a medical degree and an MBA from the University of Calgary. In her inspiring talk, entitled “Marrying Business and Medicine: Toe-ing a Fine Line”, she described how she dealt with a clinical problem (diabetic foot ulcers), came up with an innovation that optimized patient care, started her own company and delivered her product to market to enhance the health of the community. She clearly illustrated how to complete the full circle, from identifying a clinical problem to developing and providing a solution that both enhances clinical care and patient health as well as reduces health care costs and hospital admissions. The research symposium was an outstanding success and the abstracts are included in companion article in CIM.

Is it possible for conservative Protestant groups to survive in secular institutional settings? Here, Bramadat offers an ethnographic study of the Inter-Varsity Christian Fellowship (IVCF) at McMaster University, a group that espouses fundamentalist interpretations of the Bible, women's roles, the age of the earth, alcohol consumption, and sexual ethics. In examining this group, Bramadat demonstrates how this tiny minority thrives within the overwhelmingly secular context of the University.

When Harlequin Enterprises acquired British publisher Mills & Boon in 1972, the merged firm became the world’s dominant publisher of popular romance novels. Little is known, however, about the role that innovative marketing strategies played in the growth of these two romance publishing companies, especially their use of product sampling, direct mail, product standardization, and what was known at Mills & Boon as the “personal touch.” Through research in the Mills & Boon company archive at the University of Reading, the Grescoe Archive at the University of Calgary, as well as an analysis of company histories, trade publications, interviews, and marketing techniques, this study reveals how Harlequin and Mills & Boon took a different approach to product promotion than traditional publishers. Their innovation was to incorporate consumer goods marketing strategies, familiar to other industries, that disrupted and redefined standard practices of book publishers.

PURPOSE:To evaluate training in infectious diseases, determining which components of the training program best prepare residents for their career choices and where improvements are needed.METHOD:A cross-sectional survey was mailed to all 14 physicians who had graduated from both the Adult and Paediatric Infectious Diseases Training Program at the University of Calgary from 1985 to 1998. Responses about the adequacy of training were measured using a Likert-type scale and a qualitative questionnaire.RESULTS:Of 14 mailed questionnaires, nine responses were received (64%). Two-thirds of respondents were in an academic setting, and seven (78%) graduates obtained postfellowship training. The specialists in academic settings were all engaged in multiple nonclinical activities. The clinical and diagnostic microbiological components of training received the highest scores in terms of adequacy of training.CONCLUSION:Graduates of the University of Calgary training program indicated an overall satisfaction with their training. However, improvements are needed in career counselling, health administration, antibiotic utilization, infection prevention and specialized outpatient clinics. Potential strategies for addressing these issues include didactic lectures, enhanced exposure to clinical outpatient settings and provision of designated faculty mentors.

ASTIS offers over 83,000 records that provide freely available access to publications, including research and research projects, about Canada's north. This database is a product of the Arctic Institute of North America at the University of Calgary, Alberta, Canada which also maintains subsidiary regional, subject, and initiative-based databases. The subsidiary databases are all housed within and accessible through the main ASTIS database. Examples of the smaller databases include: ArcticNet Publications Database, the Nunavik Bibliography, and the Northern Granular Resources Bibliographic Database. ASTIS offers the ability to browse through its access points, including its own thesauri, thus permitting users to select and use a variety of free-text and controlled search terms.

In Us-Them-Us, several artists affiliated with the University of Calgary, and an invited poet, adopt perspectives, usually associated with that of being agents provocateur. Key themes, issues, images, symbols, and slogans associated with postcoloniality and postmodernity are well illustrated in particularly, vivid ways. Thank you Jennifer Eiserman, for working closely with the contributors, in order to, produce a special issue which highlights well established traditions of the arts and humanities. This CPI Special Issue holds up for scrutiny, central aspects of our troubling contemporary and historical life worlds.

On the basis of the analysis of the literature sources, we determined the possible range of using the method of the Earth`s natural pulse electromagnetic field. As a result of detailed analysis of domestic and foreign research, we demonstrated the relevance of conducting research focused on development of the Earth'snatural pulse electromagneticfield (or ENPEMF). Using the results of theoretical studies, the advantages and disadvantages of the ENPEMF method were determined. A complex of physical processes which preceded the development of the pulse electromagnetic field of the Earth was characterized, and the impact of mechanical deformations of rocks on the change in the condition of the electromagnetic field was experimentally proven. The main fundamentals on the determination of depth range of the ENPEMF method were examined and a new approach to interpretation of the data was suggested. We conducted an analysis of methods developed earlier of calculating geometric parameters of the sources which generate electromagnetic impulses. Their practicability at a certain stage of solving the data of geological tasks was experimentally tested. We determined the factors which affect the depth range of the ENPEMF method. A mathematical solution of the effectiveness of the ENPEMF method was suggested and determined the relations between the depth parameter of the study and the frequency of measuring and effective value of specific electric resistance. On the example of different objects, the effectiveness and correctness of the suggested method of determining the depth range parameter was proven. In particular, the theoretical results of the study were tested and confirmed on objects of different geological-morphological and engineering-technical aspects, i.e. Novo-Holyn mine in the Kalush-Holynske potash deposit and the multi-storey educational building of the University in Ivano-Frankivsk. The practicability of using the ENPEMF method in combination with other methods of electrometry for solving practical geological tasks was experimentally proven.
