The effect of sediment accumulation on the hydraulic conductivity of pervious concrete
No full textPervious concrete systems can reduce stormwater runoff, minimize non-point source pollution, and increase groundwater recharge. Engineers are often hesitant to use pervious concrete because it costs more than traditional concrete and there is the
possibility that the pervious concrete will clog prematurely; thereby removing any of the
hydraulic advantages that pervious concrete provides. Pervious concrete clogs because sediment builds on the surface by filling in all the void spaces, thus reducing its hydraulic conductivity. In this study, pervious concrete cores were used to measure the effects of
sediment accumulation on their hydraulic conductivity. Established sediment loading rates were used to measure how the hydraulic conductivity changed as sediment accumulated at or near the surface of pervious concrete. The results were used to develop
a model to predict the hydraulic conductivity of pervious concrete based on its initial hydraulic conductivity, the amount of sediment deposited at or near its surface and the soil type of the sediment. The model presented here can be used to craft better maintenance plans to extend the life of pervious concrete and use pervious concrete more efficiently.M.S.Includes bibliographical referencesby Sean Patrick Wals

No full textIn the wake of University of Maine at Orono hockey coach Sean Walsh\u27s five week-suspension for playing an ineligible player, some are wondering whether Walsh will be back at the university next year. Walsh apparently neglected to inform the admissions department at the university that the National College Athletic Association had ruled that player Jeff Tory was ineligible prior to the start of the school year

Appropriations of Irish drama by modern Korean nationalist theatre : a focus on the influence of Sean O’Casey in a colonial context
No full textMy thesis explores how a translated author on the periphery of the host culture’s
translated repertoire can be at once subversive and innovative on the colonial scene,
using as an example the case of Sean O’Casey in colonial Korea. It explores the
importation of Irish drama in modern Korean theatre during the colonial period and
examines the appropriations of O’Casey’s plays by a central Korean playwright, Yu
Chi-jin, in creating his own plays. Under Japanese colonial rule in the early twentieth
century, intellectuals perceived the supreme task for the Korean people to be the
recovery of national sovereignty and independence. The modern Korean theatre
movement which rose among Korean intellectuals and dramatists during the colonial
period was to play a major part in this task. The ultimate goal of this movement was
to establish a modern national theatre promoting Korean culture and educating the
people, thereby recovering national independence. As their modernised dramatic
polysystem was still "young", Korean intellectuals and dramatists who were
involved in the theatre movement had to borrow dramatic models from other
countries. One of the models they chose was Irish playwrights, especially those who
were involved in the Irish dramatic movement. They published or staged the works
of W.B. Yeats, Lord Dunsany [Edward John Moreton Drax Plunkett], Augusta
Gregory, J.M. Synge, St. J. Ervine, T.C. Murray and Sean O'Casey. Although
O'Casey was considered an important dramatist in the Irish dramatic movement, he
was a playwright on the periphery in the list of translated Irish dramatists in Korea
due to the colonisers’ censorship. However, he remained as a subversive and
innovative playwright on the colonial scene by virtue of being appropriated by Yu
Chi-jin who used O’Casey’s plays as models when creating his own works. In
discussing the subject matter of my thesis, I use Even Zohar’s polysystems theory as
a starting point in looking at ideological issues surrounding translation and extend
the discussion to offer a postcolonial perspective. While most translation in a
colonial context was considered as "an expression of the cultural power of the
colonisers," my thesis shifts the focus to translation as an expression of the cultural
power of the colonised. I explore how the colonised uses another colonised culture to
subvert the colonisers’ power
Isaac and His Amazing Asperger Superpowers! by M. Walsh
No full textWalsh, Melanie. Isaac and His Amazing Asperger Superpowers! Candlewick Press, 2016.This picture book is designed to help children better understand children who are on the Asperger’s/autism spectrum. Isaac, like many children with Asperger’s Syndrome, has symptoms that include needing to fidget, sensitivity to sound, exceptional memory for certain kinds of facts, and lack of verbal filters. Instead of making these as negative attributes, Melanie Walsh has used the “superhero” concept as a vehicle for their positive presentation. Telling the story in the first person allows Isaac to directly describe for the reader what his life is like. This allows readers to empathize more easily. For example, he says: “Because I’m a superhero, I have lots of things to think about. I try to remember to be friendly and say hello to people I know, but sometimes I forget. I’m not being rude.” The artwork is brightly coloured. The images are simple and easy to understand, so it does not distract from the story. This would be a good book to read out loud and discuss in a class where there is a child with Asperger’s. While it may not exactly represent all children with Asperger’s, it is a good generalization and will help other children be more accepting of others who have these “superhero” behaviours.Highly Recommended: 4 stars out of 4Reviewer: Sean BorleSean Borle is a University of Alberta undergraduate student who is an advocate for child health and safety. </jats:p

Accuracy of Nature of Call screening tool in identifying patients requiring treatment for out of hospital cardiac arrest
No full textBackground A new pre-triage screening tool, Nature of Call (NoC), has been introduced into the telephone triage system of UK ambulance services which employ National Health Service Pathways (NHSP). Its function is to provide rapid recognition of patients who may need immediate ambulance dispatch for out-of-hospital cardiac arrest (OHCA) and withholding dispatch for other calls while further triage is undertaken. In this study, we evaluated the accuracy of NoC and NHSP in identifying patients with potentially treatable or imminent OHCA.Methods This retrospective, observational study reviewed consecutive calls to a UK ambulance service between October 2016 and February 2017 in which NOC, and then NHSP were applied sequentially. Only those calls for which a corresponding electronic Patient Clinical Record was available were included. Sensitivity and specificity of NOC and NHSP for recognition of an OHCA were determined by comparing allocated priority dispositions with an OHCA Treatment Registry (OHCATR).Results Of 96 423 calls received, 71 373 were reviewed. For 590 (0.8%) of these calls, the patients received treatment for OHCA. NOC identified 458 OHCATR patients; NHSP identified 467; together they identified 496. NoC captured 29 patients not identified by NHSP; NHSP captured 38 patients not identified by NOC. For NOC sensitivity was 77.6% (95% CI 74.1 to 80.8) and specificity 86.9% (95% CI 86.6 to 87.1). NHSP sensitivity was 79.2% (95% CI 75.7 to 82.2) and specificity 93.4% (95% CI 93.2 to 93.6). NoC and NHSP combined had a sensitivity of 84.1% (95% CI 80.9 to 86.8) and specificity of 85.3% (95% CI 85.1 to 85.6).Conclusions NoC and NHSP call categorisation each achieved similar sensitivity for the identification of OHCATR, identifying most of the same patients, but each captured unique patients. Using both methods sequentially improved accuracy. The 16% of OHCATR patients not identified by either method present a challenge to ambulance dispatch systems
