The overconsolidated soils and soft rocks which form a large proportion of foundation materials in Western Canada typically have a substantial component of their total deformation of an immediate (time independent) nature. This makes them particularly suitable for application of pressuremeter testing when deformation characteristics are sought for settlement or heave analysis.The presented study is a continuation of work on pressuremeter testing carried out at the University of Alberta systematically since 1971 with a view to developing a pragmatic approach to a complex problem of foundation deformation analysis.Described in detail are pressuremeter testings on three sites in Western Canada where documented case histories of deformation behavior were available. The first case history analysed was a settlement of Mount Blackstrap near Saskatoon, Saskatchewan, which is a man-made ski hill founded on very deep till strata. The second case was the settlement of concrete silos in Calgary, Alberta, founded on a layer of dense, coarse gravel. The third study was concerned with an analysis of a load test on a bored pile embedded in Cretaceous bedrock at the Calgary Airport.At all three sites the pressuremeter derived moduli were used in back-analysis of foundation behavior and the results were compared with previously recorded field data. An agreement between the back-analysis and field data in some cases and discrepancies in others indicate the limitations of this approach to pressuremeter testing in these types of foundation materials. The results are discussed and conclusions are drawn on the basis of these as well as the previously studied case histories.

The maximum load carrying capacity of bored piles is a complex problem because it is a function of a number of factors, these factors include methods of soil exploration, ground water condition, types of grading of concrete, quantity and quality of concrete. The knowledge of Geotechnical test is important for the most economical design of the piles. This paper describes some important aspects of field investigation, design and construction of in-situ bored pile foundation, field pile load test of experience gained from the construction of the pile at a site in Aathoor in Tamil Nadu, India. The site was fully sandy soil from existing ground level. The design of bored pile under axial compression was done using Empirical formula, pile load test and by using PLAXIS 2D software. Results were compared with vertical load and settlement in this site.

Abstract Background Blastomyces helicus (formerly Emmonsia helica) is a recently described dimorphic fungus first isolated from a man who died of encephalitis in Alberta, Canada. The geographic range, epidemiology and clinical features are unknown. Methods We reviewed clinical and veterinary isolates of Blastomyces and Emmonsia at the University of Alberta Microfungus Collection and Herbarium and the UT Health San Antonio Fungus Testing Laboratory. Isolates were selected based on low B. dermatitidis DNA probe values and/or atypical morphology. DNA sequence analysis was performed. Epidemiological and clinical data were analyzed. Results Isolates of B. helicus were identified from eight human (Table 1) and five veterinary cases (Table 2). Mycelial and yeast-like phases of typical clinical isolates are shown in Figures 1 and 2, respectively. Isolates were referred from provinces and states shown in Figure 3. Conclusion Blastomyces helicus caused pulmonary and fatal disseminated disease, mainly in immunocompromised persons, and lung disease in companion animals in western Canada and US. Epidemiological investigations are needed to establish the burden of disease and geographic range of this pathogen. Disclosures All authors: No reported disclosures.

Hilb, Nora, Simon Shapiro and Sheryl Shapiro. Slither and Slide: What’s Outside. Toronto:  Annick Press, 2012. Print. Nora Hilb, who is listed as lead author on this book, is a prolific illustrator living in Argentina.  The text is by Toronto authors Simon and Sheryl Shapiro. Together, this team of three has produced an entertaining and educational book which progresses through the seasons from spring to winter. Each two page spread has four integrated parts. On the left page is a photograph of something outside. The first is of a fruit tree in blossom. On the facing page is an image of children outside, doing something that mirrors what is in the photograph.  In the first case, to mirror the tree, they are watering a plant. The accompanying text is in the form of a three line rhyme about what the children are doing. The rhyme is followed by one word in large capital letters. For example, one of the winter photographs shows a row of wind turbines and is matched with a drawing of a child with a pinwheel. The accompanying text reads, “The blustery wind/that blows in from the west/ for windmills and pinwheels, it’s really the best/ WHIRR!” One can easily imagine reading the rhyme to a child and then spelling the word out at the end as a learning activity. Many children will learn to recite the rhymes. The high-quality photographic images are the work of a variety of people. Hilb’s drawings are whimsical, with lots of bright colours and action. The page pairs are fun. The image of a waterfall is paired with an image of children at the beach dumping water from one bucket to another. The rainbow image is paired with children colouring with a rainbow of crayons. The picture of the black bear is paired with an image of a child in a bear-costume pretending to scare his Dad. Overall this is an attractive book that incorporates a little learning and lots of ways to engage and amuse small children. Highly recommended. Recommendation:  4 stars out of 4 Reviewer:  Sandy Campbell Sandy is a Health Sciences Librarian at the University of Alberta, who has written hundreds of book reviews across many disciplines.  Sandy thinks that sharing books with children is one of the greatest gifts anyone can give.

McCall Smith, Alexander.  The Great Cake Mystery: Precious Ramotswe’s Very First Case.  Illus. Iain McIntosh. New York: Anchor, 2012. Print.Adult readers around the world have been charmed by the best-selling “No. 1 Ladies’ Detective Agency” series, in which Mma Ramotswe tackles the troubling mysteries and personal problems of ordinary people, and does so by relying on her sharp wit and her extraordinary insight into human nature.  In this book, young readers will be introduced to a school girl who is destined to become a great detective.  Here, Precious Ramotswe – “one of the nicest girls in Botswana”  challenges her classmates’ assumptions in order to solve her first case. The story begins when Precious asks her beloved father to recount her favourite story: an account of the time he was “nearly eaten by a lion”.  Since young Precious can tell which parts of his story really happened and which parts are made up, her father suggests that she might become a detective someday.  His idea is soon put to the test when her classmates begin to notice that their lunch-time treats are being stolen from the outside shelf where they leave their bags during school.  When the children scapegoat a shy boy with a sweet tooth, Precious realizes that she will need to do more than find the truth, she will need to prove it.This book has the charm of the original series, and is recommended for readers aged 7-10 years old.  It offers an engaging story and several life lessons.  Further, the story offers young readers a glimpse of ordinary daily life in Africa, and the author hopes it “will inspire them to read more about that wonderful continent and its remarkable people” .In a note addressed to the reader at the back of the book, the author tells us that families have been reading his “No. 1 Ladies’ Detective Agency” series aloud together, but acknowledges that the series would be challenging for young readers to read on their own, and so this book has been written with young readers in mind.  Teachers and librarians who are fans of Mma Ramotswe will enjoy sharing her adventures with young readers, and will be pleased to find various curriculum materials at the back of the book.Highly recommended: 4 stars out of 4 Reviewer: Linda QuirkLinda is Assistant Special Collections Librarian at the Bruce Peel Special Collections Library at the University of Alberta.

At the outbreak of war in August of 1914, the University of Alberta was one of the youngest educational institutions in Canada. It boasted only 439 students and an even smaller staff. However, its support of the war at home and abroad was one of dedication and commitment far beyond what was ever expected of this small institution. The years 1914-1918 witnessed the University of Alberta become one of the leading educational institutions in Western Canada. This paper examines the university’s contribution to the war effort and chronicles its growth and maturation during these formative years.

Background: Neomycin contact sensitization rates in North America range from 7% to 13%, whereas in Europe they average approximately 1.9%. Objectives: Given that topical neomycin products are no longer readily available in Canada, the aim of this study was to examine what influence this may have had on neomycin sensitization rates in the 3 western provinces. Methods: On the basis of an observation originally communicated by L. M. Parsons and C. Zhang of the University of Calgary, which suggested significantly reduced rates of neomycin sensitization in Calgary, Alberta, Canada, a multicenter study of patch test results from 5690 patient charts was undertaken. Data from 3 other western Canadian Universities (the University of Saskatchewan, the University of Alberta, and the University of British Colombia) were analyzed. Data were available from 2001 to 2013 for the University of Saskatchewan (except 2006), whereas the University of Alberta and the University of British Columbia had data from 2009 to 2013. Descriptive statistics, trend analysis, and risk estimates were determined using SPSS version 20. Results: Sensitization rates for neomycin have decreased in western Canada and are now similar to those of Europe. Conclusions: This trend is likely influenced by the reduced availability of over-the-counter and prescription neomycin products in Canada.

Much work has been done to characterize domain-specific brain networks associated with reading, but very little work has been done with respect to spelling. Our aim was to characterize domain-specific spelling networks (SpNs) and domain-general resting state networks (RSNs) in adults with and without literacy impairments. Skilled and impaired adults were recruited from the University of Alberta. Participants completed three conditions of an in-scanner spelling task called a letter probe task (LPT). We found highly connected SpNs for both groups of individuals, albeit comparatively more connections for skilled (50) vs. impaired (43) readers. Notably, the SpNs did not correlate with spelling behaviour for either group. We also found relationships between SpNs and RSNs for both groups of individuals, this time with comparatively fewer connections for skilled (36) vs. impaired (53) readers. Finally, the RSNs did predict spelling performance in a limited manner for the skilled readers. These results advance our understanding of brain networks associated with spelling and add to the growing body of literature that describes the important and intricate connections between domain-specific networks and domain-general networks (i.e., resting states) in individuals with and without developmental disorders.

Soil Shear Strength

Polymer geogrid reinforced soil retaining walls have become commonplace, with routine design generally carried out by limiting equilibrium methods. Finite element analysis (FEA) is becoming more widely used to assess the likely deformation behavior of these structures, although in many cases such analyses over-predict deformation compared with monitored structures. Back-analysis of unit tests and instrumented walls improves the techniques and models used in FEA to represent the soil fill, reinforcement and composite behavior caused by the stabilization effect of the geogrid apertures on the soil particles. This composite behavior is most representatively modeled as enhanced soil shear strength. The back-analysis of two test cases provides valuable insight into the benefits of this approach. In the first case, a unit cell was set up such that one side could yield thereby reaching the active earth pressure state. Using FEA a test without geogrid was modeled to help establish appropriate soil parameters. These parameters were then used to back-analyze a test with geogrid present. Simply using the tensile properties of the geogrid over-predicted the yield pressure but using an enhanced soil shear strength gave a satisfactory comparison with the measured result. In the second case a trial retaining wall was back-analyzed to investigate both deformation and failure, the failure induced by cutting the geogrid after construction using heated wires. The closest fit to the actual deformation and failure behavior was provided by using enhanced fill shear strength.
