The World Intellectual Property Association (WIPO) has traditionally been focused on treaties that strengthen the rights of copyright owners. However, for nearly a decade, WIPO's Standing Committee on Copyright and Related Rights (SCCR) has been discussing the need for a treaty setting out copyright exceptions for libraries and archives. Such a treaty would require signatory nations to include in their domestic copyright laws a minimum level of exceptions (a.k.a. users' rights) that would enable libraries and archives to fulfill their public interest mission. Drawing on her experience as a representative of the International Council on Archives at SCCR, Dr. Dryden describes the current state of these discussions, including the players, the obstacles, strategies, and prospects for success. ItemCould once be enough? Support for the efficacy of the one-shot library instruction session(2013) Hayes-Bohanan, Pamela; Spievak, Elizabeth R. ItemCross-section Measurement and Thick Target Production of Terbium Radioisotopes by Enriched Gadolinium Targets(2023) wang, yizheng; GUERTIN, Arnaud; NIGRON, Etienne; haddad, ferid; Michel, Nathalie; Sounalet, ThomasIntroduction Short-lived radioisotopes of the terbium (Tb) family show great prospects in theranostics: the 149Tb can be used for alpha therapy, the 152Tb, as a positron emitter, can be applied for the positron emission tomography (PET), the 155Tb can be used for the single photon emission tomography (SPECT) and for Auger therapy, and finally, the 161Tb can be an alternative to 177Lu for β-therapy. Nevertheless, the applications of Terbium are limited at the moment due to its insufficient production and high cost: except for 161Tb, the other radionuclides are produced by nuclear spallation reactions. The use of enriched Gadolinium (Gd) targets can help to increase their availability according to the following production reactions: 152Gd(p,4n)149Tb 1, 152Gd(p,n)152Tb 1, 155Gd(p,n)155Tb 2 and 155Gd(d,2n)155Tb 3. In this work, the 155Tb is taken as a case study, and Gd2O3 enriched in 155Gd is used. Objectives of this work are on the one hand to measure the cross section of the 155Gd(d,2n)155Tb nuclear reaction induced by deuteron, and on the other hand to irradiate enriched Gd2O3 targets for thick target production with deuteron. Description of the Work or Project For the cross section measurement, thin targets (10-20 µm) are required while thicker targets are preferred for production. Therefore, two types of Gd targets with different thicknesses have been developed through two different techniques. Thin targets were manufactured via the electrochemical co-deposition technique. Uniform Ni/Gd2O3 composite targets with a thickness of 10-20 µm containing about 2 mg of enriched Gd were obtained after 35 min of deposition. These targets were irradiated at GIP ARRONAX cyclotron with deuteron beams. Cross sections of 155Tb and other Tb radionuclides (153Tb, 154Tb and 156Tb) were measured from 8 MeV to 30 MeV. These measurements give the first experimental results for the reaction 155Gd(d,x)Tb. From these results, the thick target yield and the purity of 155Tb were estimated. The irradiation parameters for thick target production were also determined from the simulation. Thicker targets were manufactured through the pelletizing technique. A uniform and compact target with a thickness of 390 µm was obtained using 0.6 g of enriched Gd2O3 powder. This target was irradiated by deuteron beams with an incident energy of 15.1 MeV and a beam intensity of 368 nA for 1 h. The production yield of 155Tb was 10.2 MBq/µAh and the purity was 89% after 14 days of decay. These results are consistent with the estimation obtained by the measured cross sections. Conclusions This work shows the possibility of using enriched gadolinium targets to produce terbium radioisotopes via biomedical cyclotrons. Cross sections of deuteron-induced reactions on enriched Gd were measured and a test of thick target production was carried out. As for large batch production, higher intensity and longer irradiation time will be necessary. To this end, specific encapsulation and cooling systems will also be designed and in addition, pure metal Gd targets with better thermal conductivity will be developed. ItemCrown copyright: More than just an outdated provision(2019-05-30) Wakaruk, AmandaPresentation at ABC Copyright 2019. Conference program abstract: Section 12 of the Copyright Act is at odds with the aims of Open Government and many government works have become inaccessible, or even been lost due to Crown copyright chill. This session will report on recent advocacy work to persuade Canada's federal government to update an antiquated and undemocratic copyright provision. ItemCultural Appropriation in Fashion: Is Copyright the Answer?(2019-05-31) Vézina, BrigitteCultural appropriation cases spark passionate debate because while fashion's borrowing of stylistic elements from other cultures is common practice, it can in reality be offensive to the holders of source cultures. Misinterpretation or disregard for the cultural significance of a traditional cultural expression (TCE), even unintentional, can have drastic consequences for its holders. Calls for action to curb appropriation emphasize a need for indigenous peoples to have better control over their TCEs. Cultural appropriation may be explained by the jarring relationship between TCEs and copyright. While TCEs, such as traditional designs or motifs, are a product of the human mind, it is difficult to protect them within the existing copyright system, which casts most TCEs into the public domain. For instance, protection remains unavailable for TCEs that have been passed down the generations and fail to meet the originality criterion. This presentation explains the concept of cultural appropriation and illustrates it with multiple examples from fashion. It shows how copyright law fails to provide adequate protection to TCEs and thus make them vulnerable to appropriation. The presentation concludes by showing how copyright principles, particularly moral rights, could be adapted to offer strong protection to TCEs against cultural appropriation. ItemCUSMA & Technical Protection Measures(2019-05-30) Tiessen, RobertIf CUSMA (aka USMCA or MUSCA) is ratified it will severely limit the ability of the Canadian Government to limit the impact technical protection measures on Canadians and Canadian libraries. Section 41 of the Copyright Act is already a Canadianized version of the US Digital Millennium Copyright Act. After CUSMA is ratification, the Government will be extremely limited in making any changes to Section 41 of our Copyright Act because of the limits placed on Canada (and Mexico and the US) by the trade agreement. Going against CUSMA would require Canada to either convince both of its trade partners to amend CUSMA; or it would need to withdraw from the agreement. This presentation will take a look at how TPMs have evolved in international arena from the WIPO Copyright Treaty in 1996 through to current times. Then it will look at what kind of flexibility and exceptions CUSMA does allow member countries and what kinds of regulations or amendments to the Copyright Act that we might want to lobby for. ItemThe Decline of Collective Copyright Licensing in Canada's Post-Secondaries Explained Using the Theory of Fields(2019-05-31) Taylor, DonaldFligstein's and MacAdam's Theory of Fields was used to analyze how Access Copyright lost its incumbent advantage in the traditionally stable field of copyright administration in Canadian post-secondaries and why that field is still unsettled today. Theory of Fields considers actions rather than motives and explains how a field moves into crisis using the concepts of: strategic action fields composed of incumbents (Access Copyright) and challengers (post-secondaries); external shocks to a field (e.g. court rulings); the social skill of the actors, particularly how an inability to envision alternatives leads to prolonged disruption. A field enters a crisis when the challenger(s) or incumbent act in ways which causes others to attempt to disrupt the status quo. Through interviews with copyright professionals and administrators actively involved at the beginning of the period of contention (2010-2012), analysis of institutional communications and records, and analysis of judicial and tribunal decisions, I used the Theory of Fields to analyze the actions of groups in the field of post-secondary copyright management and in proximate fields such as government and the courts. This approach moves us away from hyperbole and the "us against them" paradigm with its oversimplifications of "Access Copyright got too greedy" and "universities are trying to rip off creators". The presentation, using the Theory of Fields, will demonstrate how the actions of Access Copyright and of organizations like AUCC (now Universities Canada) led post-secondaries to challenge the status quo and how a series of actions/reactions, along with a lack of skilled social action by both incumbents and challengers, naturally brought us to the current period of contention in copyright management in the post-secondary environment. ItemDigital literacy skills as determinants of job satisfaction and career progression of academic library staff(2013) Itsekor, Victoria; Oyewole, Oluwatofunmi Jesudunni ItemDoes the VIVO Harvester populate bibliographic references for an institutional instance of VIVO effectively?(2013) Eldredge, Jonathan; Kroth, Philip; Hannigan, Gale; Murray-Krezan, Cristina; Carr, Richard; Weagel, Edward; Hantak, Chad ItemDOMESTIC PRODUCTION OF Mo-99 AND Ac-225 USING COMMERCIAL PWR AND FAST EXPERIMENTAL REACTOR JOYO IN JAPAN(2023) Takaki, Naoyuki; Iwahashi, Daiki; Sasaki, Yuto; Maeda, ShigetakaThe production technology of medical radioisotopes (RI) using existing nuclear fission reactors has been studied to improve/achieve their domestic preparedness in Japan. The target nuclides currently considered in our project are Mo/Tc which is the most commonly used ones in medical diagnosis and Ac-225 which is recently known as effective alpha emitting nuclide for targeted alpha-particle therapy. Existing fission reactors, PWRs and Joyo in Japan, have potentials to work as excellent facilities for medical isotope production, as by-products of heat/electricity generation without consuming electricity and needs for new plant construction. ItemDon't lose it - use it! A guide to archiving library and information science research data(2013) Marshall, Joanne Gard; Thompson, Cheryl; Morgan, Jennifer Craft; Rathbun-Grubb, Susan; Wells, Amber L. ItemThe Evolving Landscape of Radioisotopes in Modern Medicine(2023) Schaffer, PaulIntroduction After decades of development, an increasing repertoire of radioisotopes are experiencing rapid growth in demand, both for diagnostic molecular imaging (MI), but also targeted radionuclide therapy (TRT) – two modalities with great potential for the identification and treatment of difficult-to-treat diseases, including micro-metastatic cancers, antibiotic-resistant bacterial infections and viral infections. Clinical MI agents (specifically PET and SPECT radiotracers) were dominated for years by a small group of short-lived, main-group positron-, and metallic single-photon emitting radioisotopes. However, recent advances in technologies in and around solid targets and metal isotope production are now enabling cyclotron centres to produce and distribute many emerging and important radionuclides for clinical use. On the TRT front, recent clinical results demonstrating the efficacy of beta- and alpha-emitting radiopharmaceuticals toward advanced, metastatic disease have triggered a global pursuit for new drugs. Couple this with increasing supply of promising alpha-, beta- and Auger-emitting radionuclides, personalized diagnostic, therapeutic and theranostic medicine is closer to reality now than ever before. Researchers at facilities such as TRIUMF are playing an active and important role in developing and translating new technologies that are paving the way for the discovery and translation of radioisotopes and radiopharmaceuticals that will ultimately enable the paradigm of personalized molecular medicine. Description of the Work or Project Many of the ~1400 medical cyclotrons around the world today operate between 16 and 24 MeV , an ideal range for producing, among others, isotopes including 99mTc [2,3], 68Ga , 64Cu and 89Zr . Efforts at TRIUMF have led to the development of a solid target transfer and irradiation system, and solid target processing chemistry which has demonstrated a high-yield, automated method for producing GBq-TBq quantities of these isotopes using up to 500 μA of ~13-22 MeV protons. Fully automated dissolution/separation processes along with regulatory filings now allow for cyclotron-produced materials to substitute for other sources used in the clinic today. On the therapeutic isotope front TRIUMF is scaling-up processes to produce 225Ac via the high-energy proton irradiation of 232Th, with the aim of implementing a scalable and routine production operation capable of supporting multiple clinical trials . Targets containing 0.5 mm thick, 11 g thorium foils were irradiated to12,500 μAh with ~450 MeV protons using TRIUMF’s 500 MeV Isotope Production Facility (IPF), producing GBq quantities of 225Ac, 225Ra, 228Th, 212Pb, among a number of other alpha-emitting isotopes of interest . A discussion will include recent experiences with target chemistry automation, product quality control, and Th-spallation waste handling and disposal. Conclusions This presentation will provide a summary update on the development and implementation of several newer technologies toward direct cyclotron-production of various emerging radionuclides across a fleet of 13 to 520 MeV cyclotrons located at TRIUMF and its partner institutions.

ItemImpact of research on practice for Canadian academic libraries(2013) Murphy, Sharon ItemINVESTIGATING THE CONCENTRATION OF RADIONUCLIDES IN WELLS USED AS DRINKING IN NORTHERN NIGERIA; A CASE STUDY OF JOS METROPOLIS(2023) Godwin, IniThe health impacts of nuclear radiation caused by increased human activities in the environment cannot be overlooked. Based on this, 18 well water samples were collected from various locations throughout Jos Metropolis, Jos North LGA, Plateau State, Nigeria, and the following radionuclide concentration activities were examined: 40K, 210Pb, 224Ra, 232Th, and 238U, using a high-resolution gamma ray spectrometer. In well water samples used as drinking water, the assessed average concentration activities of 40K, 210Pb, 224Ra, 232Th, and 238U were determined. The mean concentration ranges from 1.36±0.51 Bq l_1 to 5.75±1.30 Bq l_1. The mean concentration of 40K in well water samples ranges from 3.80±1.19 Bq l_1 to 2.05±0.30 Bq l_1. The mean concentration of dissolved 224Ra in water samples collected varies from 5.75±1.30 Bq l_1 to 1.95±0.58 Bq l_1. 210Pb has an average concentration of 2.68 ± 0.80 Bq l_1 to 1.97±0.87 Bq l_1. 232Th and 238U had average concentrations of 3.09 ± 0.57 Bq l_1 to 1.89±0.24 Bq l_1 and 5.41 ± 1.37 Bq l_1 to 1.36±0.51 Bq l_1 respectively. 210Pb and 224Ra were slightly above the recommended limits of 0.10 Bq l_1 and 1.00 Bq l_1, respectively; this can be linked to the sampled area's geological formation. 232Th and 238U were within the accepted standard limits of 1.00 Bq l_1 and 10.00 Bq l_1 recommended by the WHO (World Health Organization) and ICRP (International Commission on Radiological Protection). Well water samples from Jos North LGA, showed activity concentrations of detected radionuclides in the following order: 210Pb>224Ra>238U>40K>232Th. ItemInvestigating the scholarly communications needs of faculty at the University of Saskatchewan: Is there a role for the University Library?(2013) Dawson, Diane (DeDe)This study seeks to understand the current publishing behaviours and attitudes of faculty, across all disciplines, at the U of S in response to the growing significance of OA publishing and archiving. The broad objective of this research is to discover what the current and emerging needs of U of S researchers are in order to determine if scholarly communications services are in demand here. And, if so, to provide an evidence-based foundation for the potential future development of such a program of services at the University Library.
