    Adding a librarian to an upper extremity surgical and therapy practice has many advantages (educational, research, remaining on the cutting edge of technology). As an embedded team member, the librarian at the Indiana Hand to Shoulder Center prepares literature reviews, creates Google Scholar Alerts for individual clinicians, and introduces developing technologies such as 3-dimensional printers, Smartphone Apps, and online access to nontraditional resources. With the librarian relieving clinicians of these responsibilities, surgeons can devote more time to clinical and research activities. Private practices unable to support their own librarian could share access to a librarian via Skype, Face Time, and video conferencing. Another small practice alternative is contracting services from a local medical school library that designates a librarian as its liaison. Copyright © 2017 American Society for Surgery of the Hand.

    Dusts are one of the main air pollutants emitted during cement manufacturing. A substantial part of these are breathable particles that are less than 10 μm in diameter (PM10), which represent a potential threat for the health of the exposed population. This study aimed at evaluating the short-term effects of PM10 concentrations on the health of children, aged 6-14 years, who attended the schools in Fumane (Italy), in proximity (1.2 km) to a large cement plant. School absenteeism was used as a proxy indicator of child morbidity. Time series of daily school absences and PM10 concentrations were collected for 3 school-years from 2007 to 2010 (541 school-days, 462 children on average). The associations between PM10 concentrations and school absence rates in the same day (lag0) and in the following 4 days (lag1 to lag4) were evaluated using generalised additive models, smoothed for medium/long term trends and adjusted for day of the week, influenza outbreaks, daily temperature and rain precipitations. The average concentration of PM10 in the period was 34 (range: 4-183) μg/m(3). An average 10 μg/m(3) increase of PM10 concentration in the previous days (lag0-4) was associated with a statistically significant 2.5% (95%CI: 1.1-4.0%) increase in the rate of school absences. The highest increase in the absence rates (2.4%; 95%CI: 1.2-3.5%) was found 2 days after exposure (lag2). These findings provide epidemiological evidence of the acute health effects of PM10 in areas with annual concentrations that are lower than the legal European Union limit of 40 μg/m(3), and support the need to establish more restrictive legislative standards.

    McCaffrey, Erin

    2014-01-01

    The rise of online education at institutions of higher learning, together with the increasing cost of higher education, lead some to suggest that online (or distance) education will eventually become the dominant form of higher learning. This has particular significance for librarians. This casebook, a blueprint for embedding academic librarians in online environments, from undergraduate to science-based graduate schools to MOOCs is the first to explore how librarians can play a key role in the virtual academic landscape. The authors, academic librarians representing a broad range of colleges and universities, look at the evolution of the embedded librarian from physical to virtual, suggest how to develop and implement unique programs in and out of the classroom, and explain how to scale programs once they are embedded. This book is suitable for professional collections in academic libraries of all sizes and types. It is also suitable for collections in schools of library and information science.

    2012-01-01

    When you picture a librarian, what do you imagine? An old white woman with glasses and a prudish disposition? That is the image that many people conjure up when asked to picture a librarian; with 82 per cent of the professional force being female and the average age of a librarian at 45, coupled with popular stereotypical images, it is difficult to dispute the perceptions. But there is more to librarians than meets the eye. This book will explore the origin of the image and popular media images of the librarian, in addition to the effects of the stereotype, and the challenges to the perception

    Since fall 2009, reference librarians at The George Washington University's Himmelfarb Health Sciences Library have been embedded in online classes through Blackboard within the School of Nursing and School of Medicine and Health Sciences. The authors sought to determine the types of questions asked of the librarian, with the goal of informing future interactions with distance education classes to help develop a standard "protocol" for working with this population of students. Eighty-two questions were categorized and qualitatively analyzed. The findings have prompted librarians to explore tools such as Elluminate Live!, a tool that allows librarians to provide synchronous instruction within the Blackboard environment.

    2014-07-01

    The study gathered data about librarians' membership in institutional animal care and use committees (IACUCs) and their professional activities supporting animal researchers. Libraries affiliated with medical schools that were members of the Association of American Medical Colleges were surveyed. A survey was distributed via library directors' email discussion lists and direct email messages. Sixty surveys were completed: 35 (58%) reported that librarians performed database searches for researchers, and 22 (37%) reported that a librarian currently serves on the IACUC. The survey suggests that academic health sciences librarians provide valuable, yet underutilized, services to support animal research investigators.

    Full Text Available The information explosion of the latter half of the twentieth century, gave rise to online databases and various information media that gradually impacted on the very physical environment of the library. It transformed the librarians’ role. Reference librarians are no exception. The present study aims to investigate the need or lack of need to reference librarians within the digital domains based on the views expressed by LIS authorities in Iran. It would attempt further, to identify the qualities required for such librarian should a need for her/his expressed. The research, while descriptive in nature, was based on analyzing the results obtained by the checklist devised by the authors. LIS Specialist sample was composed of 57 people who filled the checklist. Findings show that there is a significance between employing ICT and need for a reference librarian. LIS experts in Iran believe that introduction of ICT, especially Internet and the WWW not only didn’t decrease the need for such librarians, but has caused the reference librarian to attain a more important and better status than before. Findings further demonstrated that while Iran is not a signatory to the international copyright conventions, the Iranian reference librarians are fully committed to observing author’s copyright and intellectual rights and frown on using software crackers.

    This study investigated health sciences librarians' knowledge and skill-based readiness to partner on sponsored research involving human participants. The authors developed and deployed, at two time points, a web-based survey on nine indicators of research activities with response choices reflecting the transtheoretical model of stages of behavior change. Librarians with research experience or membership in the Medical Library Association Research Section reported higher levels of having completed indicators. Our results suggest that creating awareness in precontemplation responders could encourage skill development. Mentoring and continuing education could support librarians who are contemplating or preparing to perform indicator activities.

    2015-10-01

    Full Text Available What significant changes are librarians and library technicians experiencing in their roles? A survey put forward across Canada to librarians and library technicians addressing this question was conducted in February 2014. Eight hundred eighty-two responses were obtained from librarians, defined as MLIS graduates, and library technicians, defined as graduates from a two-year library diploma program. Respondents needed to have been employed in the last two years in these roles and students of either an MLIS or LIT program were also welcome to participate. The results suggest that both librarians and library technicians perceive their roles as growing in scope and complexity and that the lines of responsibility are blurring. A majority of respondents indicated that they perceive a change in their roles in the past five years and commented on what the perceived changes were. Librarian and library technician roles may be shifting away from what may be viewed as traditional or clearly defined responsibilities and both librarians and library technicians may be taking on new tasks as well as experiencing task overlap. All library staff will need to be fluid, adaptable, and open to change. Library school curricula and workplace training need to incorporate the development of these competencies. Quels sont les changements importants éprouvés par les bibliothécaires et les bibliotechniciens dans leurs rôles?

    Full Text Available During a well cementing special place belongs to the cement slurry design. To ensure the best quality of cementing, a thorough understanding of well parameters is essential, as well as behaviour of cement slurry (especially at high temperatures and application of proven cementing techniques. Many cement jobs fail because of bad job planning. Well cementing without regarding what should be accomplished, can lead to well problems (channels in the cement, unwanted water, gas or fluid production, pipe corrosion and expensive well repairs. Cementing temperature conditions are important because bot-tomhole circulating temperatures affect slurry thickening time, arheology, set time and compressive strength development. Knowing the actual temperature which cement encounters during placement allows the selection of proper cementing materials for a specific application. Slurry design is affected by well depth, bottom hole circulating temperature and static temperature, type or drilling fluid, slurry density, pumping time, quality of mix water, fluid loss control, flow regime, settling and free water, quality of cement, dry or liquid additives, strength development, and quality of the lab cement testing and equipment. Most Portland cements and Class J cement have shown suitable performances in geot-hermal wells. Cement system designs for geothermal wells differ from those for conventional high temperature oil and gas wells in the exclusive use of silica flour instead of silica sand, and the avoidance of fly ash as an extender. In this paper, Portland cement behaviour at high temperatures is described. Cement slurry and set cement properties are also described. Published in literature, the composition of cement slurries which were tested in geothermal conditions and which obtained required compressive strength and water permeability are listed. As a case of our practice geothermal wells Velika Ciglena-1 and Velika Ciglena-la are described.

    1991-01-01

    In the information age of the 1990s, the clinical medical librarian (CML) concept, like many other personalized library services, is often criticized as being too labor-intensive and expensive; others praise its advantages. To determine the attitudes of medical school library directors and clinical department heads toward implementation and feasibility of a CML program, forty randomly selected medical schools were surveyed. A double-blind procedure was used to sample department heads in internal medicine, pediatrics, and surgery, as well as health sciences library directors identified by the Association of Academic Health Sciences Library Directors (AAHSLD) annual statistics. The survey instrument was designed to measure responses to the following attitudinal variables: acceptance and nonacceptance of a CML program; importance to patient care, education, and research; influence on information-seeking patterns of health care professionals; ethical issues; CML extension services; and costs. Seventy-nine usable questionnaires out of a total of 120 (66%) were obtained from clinical medical personnel, and 30 usable questionnaires out of a total of 40 (75%) were obtained from medical school library directors. Survey results indicated significant differences between clinical medical personnel and library personnel regarding attitudes toward CML influence on information-seeking patterns, ethics, alternative CML services, and costs. Survey results also indicated a continuing strong support for CML programs in the medical school setting; however, differences of opinion existed toward defining the role of the CML and determining responsibility for funding.

  9. Lunar cement

    Science.gov (United States)

    Agosto, William N.

    1992-01-01

    With the exception of water, the major oxide constituents of terrestrial cements are present at all nine lunar sites from which samples have been returned. However, with the exception of relatively rare cristobalite, the lunar oxides are not present as individual phases but are combined in silicates and in mixed oxides. Lime (CaO) is most abundant on the Moon in the plagioclase (CaAl2Si2O8) of highland anorthosites. It may be possible to enrich the lime content of anorthite to levels like those of Portland cement by pyrolyzing it with lunar-derived phosphate. The phosphate consumed in such a reaction can be regenerated by reacting the phosphorus product with lunar augite pyroxenes at elevated temperatures. Other possible sources of lunar phosphate and other oxides are discussed.

    2007-09-01

    The aims of the study were to examine whether and how librarians with a generalist background can transfer to roles demanding more expert knowledge in the health sector. The objectives were (i) to compare the education and training needs of health librarians with science degrees with the education and training needs of health librarians with arts and humanities degrees; (ii) to compare the education and training needs of librarians working in the National Health Service (NHS) sector with the education and training needs of librarians working for the health sector but within higher education. Face-to-face interviews with 16 librarians, a convenience sample of librarians working in the Thames Valley NHS region. The main findings confirmed that structured continuing professional development (CPD) is required to meet the rapidly changing needs in the health sector. The emphasis ought to be on teaching skills, outreach work, marketing and promotion, research skills and methods, subject knowledge and terminology, and management skills. Library school curricula do not appear to meet the demands of medical library posts. A first degree in scientific subjects is advantageous in the early stages of a career but diminishes with continuing training and experience. There is no evidence of a significant difference in training needs and provision between the librarians in NHS posts as opposed to those in higher education (HE) posts. The conclusions suggest that library schools need to update their programmes to include teaching skills, advanced search skills, project management skills, research methods, with more practical exercises. Particular attention should be given to librarians with a first degree in non-scientific subjects in terms of time allocated for CPD, quality of training and access to reliable mentorship.

    Full Text Available Our aim is to identify the steps that librarians can take concerning altmetrics within the framework of the research support services. The current bibliography on altmetrics has been reviewed. A survey has also been carried out of librarians of Spanish universities to find out their degree of involvement in the matter and the setting up of relevant initiatives. Likewise, a thorough study which would enable librarians to find out about the use which their researchers make of social networks and the interest that they may have in altmetrics is needed. This research offers a user guide for librarians as an orientation in their activities and initiatives related to altmetrics, as well as a list of arguments which justify the reasons why librarians should undertake these initiatives. We contribute a view of altmetrics from the perspective of librarians as a strategic element of dissemination and training in altmetrics.

  10. Producing cement

    Energy Technology Data Exchange (ETDEWEB)

    Stone, E G

    1923-09-12

    A process and apparatus are described for producing Portland cement in which pulverized shale is successively heated in a series of inclined rotary retorts having internal stirrers and oil gas outlets, which are connected to condensers. The partially treated shale is removed from the lowermost retort by a conveyor, then fed separately or conjointly into pipes and thence into a number of vertically disposed retorts. Each of these retorts may be fitted interiorly with vertical arranged conveyors which elevate the shale and discharge it over a lip, from whence it falls to the bottom of the retorts. The lower end of each casing is furnished with an adjustable discharge door through which the spent shale is fed to a hopper, thence into separate trucks. The oil gases generated in the retorts are exhausted through pipes to condensers. The spent shale is conveyed to a bin and mixed while hot with ground limestone. The admixed materials are then ground and fed to a rotary kiln which is fired by the incondensible gases derived from the oil gases obtained in the previous retorting of the shale. The calcined materials are then delivered from the rotary kiln to rotary coolers. The waste gases from the kiln are utilized for heating the retorts in which the ground shale is heated for the purpose of extracting therefrom the contained hydrocarbon oils and gases.

    effort was made to include students who were absent. Results were tabulated as percentages of responses, and presented in tables related to the themes of the four research questions.Main results – Throughout the study, students reported very few strategies for effective Internet searching. They cited friends and family members rather than teachers as their main sources for support, and reported self‐taught trial and error as the most common method of learning search strategies. Despite their lack of effectiveness, most students considered themselves “good” or “very good” at finding the information they need for school purposes. Most of the students used very few of the strategies associated with effective searching that have been stated in prior research studies.• Research Question One: Use of Strategies and Techniques for Information‐Seeking on the Internet Only 15% of students used Boolean operators regularly. Over 70% of students did not know how to eliminate commercial sites, use particular features, limit searches to recently updatedp ages or limit searches to the title section of a Web page.• Research Question Two: Knowledge of World Wide Web Search Engines. Google was the overwhelming choice, with 66.7% percent of students reporting that they used it regularly. Other search engines were used from 0 to 22%.• Research Question Three: Students’ Perception of Their Information‐Seeking Ability on the Internet 81.3 % of students reported their abilities as good or very good. Only 5% felt their abilities were poor.• Research Question Four: How Students Learn What They Know About Information‐Seeking on the Internet 72.7% reported self‐teaching strategies. 39.8% relied on friends or classmates, 36.8 % relied on teachers. 2.5% reported librarians as a source Of the students who reported self‐teaching,53% used trial and error, 6.6% used help screens and 4% searched for assistance. 80.8% of students who reported teachers as a source for

    Full Text Available By mixing several binder materials and additions with different degrees of fineness, the packing density of the final product may be improved. In this work, ultrafine cement and silica fume mixes were studied to optimize the properties of cement-based materials. This research was performed in mortars made of two types of cement (ultrafine Portland cement and common Portland cement and two types of silica fume with different particle-size distributions. Two Portland cement replacement ratios of 4% and 10% of silica fume were selected and added by means of a mechanical blending method. The results revealed that the effect of the finer silica fume mixed with the coarse cement enhances the mechanical properties and pore structure refinement at a later age. This improvement is somewhat lower in the case of ultrafine cement with silica fume.

    To identify competencies for medical librarians and get these validated from head librarians and employers. The survey method was used. A structured questionnaire, listing 84 competency statements, covering eight areas, prepared after extensive literature review, expert scrutiny and pilot testing, using a 5-point Likert scale was distributed among the head librarians and chairpersons of library committees (CLC) in 115 medical libraries. Sixty seven (58%) useable responses were received from head librarians and 63 (55%) from CLC. Of the 84 competency statements 83 were validated by the head librarians, 44 receiving four or higher mean score while the other 39 statements getting mean scores in the range of 3.97 and 3.06. The CLC validated 80 statements. Only 27 statements received four or higher mean score from CLC while the other 53 got mean scores in the range of 3.97 and 3.22. Medical librarians are required to be well versed with all those competencies which are needed for general librarianship. In addition, they are expected to have adequate knowledge of health sciences environment including medical terminologies and concepts. Sound knowledge of some competencies specific for medical libraries is an additional requirement for library personnel. © 2012 The authors.

      Previous systematic reviews have indicated limited evidence and poor quality evaluations of clinical librarian (CL) services. Rigorous evaluations should demonstrate the value of CL services, but guidance is needed before this can be achieved.   To undertake a systematic review which examines models of CL services, quality, methods and perspectives of clinical librarian service evaluations.   Systematic review methodology and synthesis of evidence, undertaken collaboratively by a group of 8 librarians to develop research and critical appraisal skills.   There are four clear models of clinical library service provision. Clinical librarians are effective in saving health professionals time, providing relevant, useful information and high quality services. Clinical librarians have a positive effect on clinical decision making by contributing to better informed decisions, diagnosis and choice of drug or therapy. The quality of CL studies is improving, but more work is needed on reducing bias and providing evidence of specific impacts on patient care. The Critical Incident Technique as part of a mixed method approach appears to offer a useful approach to demonstrating impact.   This systematic review provides practical guidance regarding the evaluation of CL services. It also provides updated evidence regarding the effectiveness and impact of CL services. The approach used was successful in developing research and critical appraisal skills in a group of librarians. © 2010 The authors.

Similar data is expected from Schlumberger, and an analysis of this data will be completed in the following phases of the project. Quality control testing of materials used to formulate ULHS cements in the laboratory was completed to establish baseline material performance standards. A testing protocol was developed employing standard procedures as well as procedures tailored to evaluate ULHS and foamed cement. This protocol is presented and discussed. Results of further testing of ULHS cements are presented along with an analysis to establish cement performance design criteria to be used during the remainder of the project. Finally, a list of relevant literature on lightweight cement performance is compiled for review during the next quarter

  17. Renewed roles for librarians in problem-based learning in the medical curriculum.

    Science.gov (United States)

    Mi, Misa

    2011-01-01

    Problem-based learning (PBL) is a teaching-learning process or method of instruction that is widely used in medical education curricula. Librarians play important roles as facilitators for PBL as well as guides for information resources. Involvement in PBL activities presents unique opportunities to incorporate library resources and instruction into the medical curriculum. This article reviews the problem-based learning method within the conceptual framework of the learning theory of constructivism. It describes how a medical librarian at a U.S. medical school used emerging technologies to facilitate PBL small group case discussions, guide students to quality information resources, and enhance the learning environment for the PBL process.

    2013-04-01

    Full Text Available Librarians address all levels of information needs for the university: its acquisition, its production, its storage, and instruction for its safe and gainful use. Most of today's college students have a high degree of computer literacy but are weak in their abilities to determine the quality of the information that is so readily available. Students need to be taught to find, evaluate, and use information in an academically-oriented manner in order to solve complex problems. Good library skills are integral to academic success. In conjunction with research and teaching faculty, librarians create a framework for knowledge acquisition in the evolving university education.

    1996-07-01

    The marginal adaptation of full coverage restorations is adversely affected by the introduction of luting agents of various minimum film thicknesses during the cementation process. The increase in the marginal opening may have long-term detrimental effects on the health of both pulpal and periodontal tissues. The purpose of this study was to determine the effects of varying seating forces (2.5, 12.5, 25 N), venting, and cement types on post-cementation marginal elevation in cast crowns. A standardized cement space of 40 microns was provided between a machined gold crown and a stainless steel die. An occlusal vent was placed that could be opened or closed. The post-cementation crown elevation was measured, following the use of two commercially available capsulated dental cements (Phosphacap, and Ketac-cem Applicap). The results indicate that only the combination of Ketac-Cem Applicap and crown venting produced post-cementation crown elevation of less than 20 microns when 12.5 N seating force was used. Higher forces (25 N) and venting were required for comparable seating when using Phosphacap (19 microns). The amount of force required to allow maximum seating of cast crowns appears to be cement specific, and is reduced by effective venting procedures.

    2015-12-01

    Full Text Available The purpose of the paper is to investigate the level of ICT related IL skills of librarians in COE libraries and to know some challenges librarians face in acquiring IL skills. Descriptive survey method was adopted using questionnaire.The study covered professionals and para-professional librarians in federal, state and private Colleges of Education libraries in the South-South and South-East geo-political zones of Nigeria. The findings revealed that the librarians rated their information literacy skills to be average. A correlation of the overall assessment of the librarians’ IL skills with variables such as institution, gender, years of experience and qualifications revealed differences among the librarians. The study also revealed that the librarians acquired their IL skills through different channels such as friends and colleagues, self-practice, workshops, conferences and seminars, and through on the job training. Only a few indicated that they acquired their IL skills through library schools. Lack of training, irregular power supply, poor Internet connectivity, inadequate facilities (computers, and lack of time were identified as some of the challenges to acquire IL skills.

    2018-03-01

    The paper suggests design principles of pavement cement concrete, which covers optimization of compositions and structures at the stage of mixture components selection due to the use of plasticizing agents and air-retaining substances that increase the viability of a concrete mixture. It also demonstrates advisability of using plasticizing agents together with air-retaining substances when developing pavement concrete compositions, which provides for the improvement of physical and mechanical properties of concrete and the reduction of cement binding agent consumption thus preserving strength indicators. The paper shows dependences of the main physical-mechanical parameters of concrete on cement consumption, a type and amount of additives.

  10. Radioactive waste cementation

    International Nuclear Information System (INIS)

    Soriano B, A.

    1996-01-01

    This research was carried out to develop the most adequate technique to immobilize low and medium-activity radioactive waste. different brands of national cement were used, portland and pozzolanic cement. Prismatic and cylindrical test tubes were prepared with different water/cement (W/C) relationship. Additives such a as clay and bentonite were added in some other cases. Later, the properties of these test tubes were evaluated. Properties such as: mechanical resistance, immersion resistance, lixiviation and porosity resistance. Cement with the highest mechanical resistance values, 62,29 MPa was pozzolanic cement for a W/C relationship of 0,35. It must be mentioned that the other types of cements reached a mechanical resistance over 10 MPa, a value indicated by the international standards for transportation and storage of low and medium-activity radioactive waste at a superficial level. However, in the case of immersion resistance, Sol cement (portland type I) with a W/C relationship of 0,35 reached a compression resistance over 61,92 MPa; as in the previous cases, the other cements reached a mechanical resistance > 10 MPa. Regarding porosity, working with W/C relationships = 0,35 0,40 and 0,45, without additives and with additives, the percentage of porosity found for all cements is lower than 40% percentage indicated by international standards. With regard to the lixiviation test, pozzolanic cement best retained Cesium-137 and Cobalt-60, and increased its advantages when bentonite was added, obtaining a lixiviation rate of 2,02 x E-6 cm/day. Sol cement also improved its properties when bentonite was added and obtained a lixiviation rate of 2,84 x E-6 cm/day for Cesium-137. However, Cobalt-60 is almost completely retained with the 3 types of cement with or without additives, reaching the limits indicated by the international standards for the lixiviation rate of beta-gamma emitter < 5,00E-4 cm/day. Characterizing the final product involves the knowledge of its

    Jantsits, G

    1974-01-01

    In Hungary the completion of a thirty-month course is required of those who wish to qualify as medium-level librarians. Medical librarians are given a special course which differs from the general course in that it covers the subjects of medical terminology and information in special literature. The latter subject is accorded the highest number of teaching hours, since the subject matter is vast and since, in addition to theory, much time must be spent on exercises and the presentation of reference books. The students become familiar with the main Hungarian and foreign information systems in the medical and related fields and with special bibliographies, encyclopedias, handbooks, and dictionaries. We take special care to familiarize students with the abstracting journals and indices. For several semesters they have homework and lesson exercises in the use of the Hungarian Medical Bibliography and Index Medicus.

  15. The CERN LEP-SPS Librarian system

    International Nuclear Information System (INIS)

    Corniaux, C.; Morpurgo, G.

    1990-01-01

    The complexity of a software working environment, such as the control system for the SPS and LEP accelerators, requires a considerable management effort. The software needed to run the machines is continuously evolving, as new releases of application and system programs are introduced rather frequency. Ideally the management effort must coordinate all the different software developers and their users (the machine operating team). A software tool, the Librarian, has been written to help them in performing this task. Its ultimate goal is to enable the accelerator operators to retain control of all the software running in the control system. All the source files needed to produce a piece of running software (a 'product') are saved together, and can be retrieved either individually or as a whole. Management of the different versions of a product is also implemented, as well as a scheme for protections and access rights depending on the type of user (Librarian manager, application manager or software developer). The data base ORACLE has been used to maintain logical links between files saved under the Librarian. (orig.)

  16. The role of veterinary medical librarians in teaching information literacy.

    Science.gov (United States)

    Dinkelman, Andrea L; Viera, Ann R; Bickett-Weddle, Danelle A

    2011-01-01

    This qualitative study seeks to determine the nature of the instruction librarians provide to veterinary medical students at all 28 United States veterinary colleges. A secondary goal of the study was to determine in what ways and to what extent librarians participated in other instructional activities at their colleges. Over half of the librarians formally taught in one or more courses, predominantly in the first two years of the veterinary curriculum. One presentation per course was most common. Over half of the librarians interviewed stated that evidence-based veterinary medicine was taught at their colleges, and about half of these librarians collaborated with veterinary faculty in this instruction. Many librarians participated in orientation for first-year veterinary students. The librarians also taught instructional sessions for residents, interns, faculty, graduate students, and practicing veterinarians. This study found that librarians teach information literacy skills both formally and informally, but, in general, instruction by librarians was not well integrated into the curriculum. This study advances several recommendations to help veterinary students develop information literacy skills. These include: encourage veterinary faculty and administrators to collaborate more closely with librarians, incorporate a broader array of information literacy skills into assignments, and add a literature evaluation course to the curriculum.

  17. Clinical librarians as facilitators of nurses' evidence-based practice.

    Science.gov (United States)

    Määttä, Sylvia; Wallmyr, Gudrun

    2010-12-01

    The aim of this study was to explore nurses' and ward-based clinical librarians' reflections on ward-based clinical librarians as facilitators for nurses' use of evidences-based practice. Nurses' use of evidence-based practice is reported to be weak. Studies have suggested that clinical librarians may promote evidence-based practice. To date, little is known about clinical librarians participating nurses in the wards. A descriptive, qualitative design was adopted for the study. In 2007, 16 nurses who had been attended by a clinical librarian in the wards were interviewed in focus groups. Two clinical librarians were interviewed by individual interviews. In the analysis, a content analysis was used. Three themes were generated from the interviews with nurses: 'The grip of everyday work', 'To articulate clinical nursing issues' and 'The clinical librarians at a catalyst'. The nurses experienced the grip of everyday work as a hindrance and had difficulties to articulate and formulate relevant nursing issues. In such a state, the nurses found the clinical librarian presence in the ward as enhancing the awareness of and the use of evidence-based practice. Three themes emerged from the analysis with the librarians. They felt as outsiders, had new knowledge and acquired a new role as ward-based clinical librarians. Facilitation is needed if nurses' evidence-based practice is going to increase. The combined use of nurses and clinical librarians' knowledge and skills can be optimised. To achieve this, nurses' skills in consuming and implementing evidence ought to be strengthened. The fusion of the information and knowledge management skill of the ward-based clinical librarian and the clinical expertise of the nurses can be of value. With such a collaborative model, nurse and ward-based clinical librarian might join forces to increase the use of evidence-based practice. © 2010 Blackwell Publishing Ltd.

    We test econometrically whether the sole Danish producer of cement holds a dominant position in the Danish market for (grey) cement. In import penetration tests, we find that its pricing and quantity decisions are independent of import price and quantity, implying that it can act to a considerable extent independently of its competitors. We also test whether it can act independently of its customers and find that its demand is inelastic with respect to its price. It thus holds a dominant posi...

  1. Embedded librarianship what every academic librarian should know

    CERN Document Server

    Russo, Michael F

    2013-01-01

    Is the embedded librarian an equal partner in the course, or is the librarian perceived as a "value-added" extra? What is the place of technology in this effort? Is there a line librarians should not cross? Taking into account both theory and practice to discuss multiple facets of the subject, Embedded Librarianship: What Every Academic Librarian Should Know thoroughly examines these questions and more from the perspectives of experienced embedded librarian contributors who have worked in higher education settings. The chapters illuminate the benefits and challenges of embedding, explain the planning required to set up an embedded course, identify the different forms of embedding, and consider information literacy instruction in various contexts. Readers who will benefit from this work include not only academic librarians but any professor who wants their students to be able to do better research in their fields.

    2009-01-01

    Objectives: The research objectives were to (1) describe the current and future roles of hospital librarians and the challenges they face and (2) find evidence supporting the hypothesis that librarians are essential to hospitals in achieving the organizations' mission-critical goals. Method: The authors used results from a previous research study that identified the five organizational mission-critical goals important to hospital administrators and then searched the literature and solicited examples from hospital librarians to describe the librarian's role in helping hospitals achieve these goals. Results: The literature supports the hypothesis that hospital librarians play important roles in the success of the hospital. Librarians support quality clinical care, efficient and effective hospital operations, continuing education for staff, research and innovation, and patient, family, and community health information needs. Conclusion: Hospital librarians fulfill many mission-critical roles in today's hospital, providing the right information at the right time in a variety of ways to enhance hospital and medical staff effectiveness, optimize patient care, improve patient outcomes, and increase patient and family satisfaction with the hospital and its services. Because hospital librarians and their services provide an excellent return on investment for the hospital and help the hospital keep its competitive edge, hospital staff should have access to the services of a professional librarian.

    A new librarian offers advice and insights about what she has learned from working at a library within a health science center. The librarian earned her MLIS in spring 2015, and while she had previous teaching experience, she realized there was much more learning needed to properly teach medical, graduate and allied health students, faculty, and residents. In this "one-year on the job" column, the librarian describes the different teaching experiences today's librarians encounter, and reflects on what she has learned from them and how they shape her view of the profession.

    De Jager-Loftus, Danielle P; Midyette, J David; Harvey, Barbara

    2014-01-01

    Providing library and reference services within a biomedical research community presents special challenges for librarians, especially those in historically lower-funded states. These challenges can include understanding needs, defining and communicating the library's role, building relationships, and developing and maintaining general and subject specific knowledge. This article describes a biomedical research network and the work of health sciences librarians at the lead intensive research institution with librarians from primarily undergraduate institutions and tribal colleges. Applying the concept of a community of practice to a collaborative effort suggests how librarians can work together to provide effective reference services to researchers in biomedicine.

    2004-04-01

    Public libraries are located in all communities, and two thirds of adults visit one each year. Libraries give the public access to computers and the Internet, and librarians offer technical assistance for accessing information. The interests and training needs of public librarians for assisting the public in accessing health information have not been addressed. One public library/librarian in each North Carolina county was randomly selected to complete a written questionnaire to assess health-related information services and librarians' skills for providing these services. 84% of librarians (83/99) completed the questionnaire. Results indicate that librarians answer more than 10 health-related questions per week, feel moderately comfortable answering these questions, and are very interested in receiving additional training for addressing health-related questions. Creating public library/public health partnerships holds much promise for enhancing the ability of community members to access desired health information.

    This study proposed to define the role and duties of librarians who provide health information service in public and medical libraries. Appropriate education, career experience and starting salary for this position are also presented. This study analysed previous research and job advertisements to understand the current needs for this position. Almost all job advertisements studied were eventually retrieved from Salary.com (US job posting site). Public libraries seeking to fill health informationist positions were even more difficult to find in any of the above locations. Therefore, the researcher attempted to find cases using various search engines, including Google, and noticed that public libraries usually post job advertisements on their website. Finally, 32 job postings were selected as suitable. Fifty-four public and medical librarians were surveyed to validate the results in Korea. Public librarians chose 'health information librarian' as the most appropriate title for this position, while medical librarians answered 'medical librarian'. Therefore, librarians providing health information service in public libraries should be called 'health information librarians', while the position in medical libraries should be called 'medical librarian'. Accordingly, job postings and academic articles will be easily accessible. Both groups marked that the position should require a bachelor's degree in both LIS and a health science field, 2 years library experience and health-related user training. Other requirements included knowledge of health resources and medical terminology, search capabilities and a focus on user-centric service. For required duties, public librarians chose accessing information resources, while medical librarians selected collection management. Health information librarians will play a vital role in the future and must therefore be educated accordingly. © 2015 Health Libraries Group.

    The objective of this project is to develop an improved ultra-lightweight cement using ultra-lightweight hollow glass spheres (ULHS). Work reported herein addresses tasks performed in the fourth quarter as well as the other three quarters of the past year. The subjects that were covered in previous reports and that are also discussed in this report include: Analysis of field laboratory data of active cement applications from three oil-well service companies; Preliminary findings from a literature review focusing on problems associated with ultra-lightweight cements; Summary of pertinent information from Russian ultra-lightweight cement literature review; and Comparison of compressive strengths of ULHS systems using ultrasonic and crush methods Results reported from the fourth quarter include laboratory testing of ULHS systems along with other lightweight cement systems--foamed and sodium silicate slurries. These comparison studies were completed for two different densities (10.0 and 11.5 lb/gal) and three different field application scenarios. Additional testing included the mechanical properties of ULHS systems and other lightweight systems. Studies were also performed to examine the effect that circulation by centrifugal pump during mixing has on breakage of ULHS.

    This study aims to describe librarians' roles in evidence-based medicine (EBM) from the librarian perspective, identify how librarians are trained to teach, and highlight preferences for professional development. A multiinstitution qualitative study was conducted. Nine medical librarians identified by their faculty as integrated into EBM training were interviewed. Participants' descriptions indicated that they were active in curriculum development, deployment (including teaching activities), and assessment to support EBM. Participants identified direct experience and workshop participation as primary methods of learning to teach. Participants desired continuing development as teachers and requested opportunities for in-person workshops, shadowing physicians, and online training.

  16. Concrete = aggregate, cement, water?

    International Nuclear Information System (INIS)

    Jelinek, J.

    1990-01-01

    Concrete for the Temelin nuclear power plant is produced to about 70 different formulae. For quality production, homogeneous properties of aggregates, accurate proportioning devices, technological discipline and systematic inspections and tests should be assured. The results are reported of measuring compression strength after 28 days for different concrete samples. The results of such tests allow reducing the proportion of cement, which brings about considerable savings. Reduction in cement quantities can also be achieved by adding ash to the concrete mixes. Ligoplast, a plasticizer addition is used for improving workability. (M.D). 8 figs

    To support its roadmap work focusing on key technologies for emissions reductions, the International Energy Agency (IEA) also investigated one particular industry: cement. Cement production includes technologies that are both specific to this industry and those that are shared with other industries (e.g., grinding, fuel preparation, combustion, crushing, transport). An industry specific roadmap provides an effective mechanism to bring together several technology options. It outlines the potential for technological advancement for emissions reductions in one industry, as well as potential cross-industry collaboration.

    2016-05-01

    Full Text Available Copyright is central to teaching activities in higher education. Using copyrighted materials in education requires careful analysis and understanding of copyright basics. A review of the literature demonstrates that librarians are the primary resource on campus for information about copyright. A sampling of small to moderate-size, private university and college websites, and a survey of the librarians at those institutions suggest that libraries and librarians are the sole providers of copyright information for their campus. This paper examines how and what kinds of copyright information librarians at private, small to moderate-size institutions provide to their patrons and offers commentary from librarians who are currently the copyright contact on campus. The authors discuss how to use copyright expertise to build a professional niche and serve the profession as well as how to identify new opportunities for professional growth and career advancement.

Most Asian librarians had the unique characters of bilingual and bicultural background. They not only played a key service role to the API communities in the U.S., but also served as a bridge between mainstream American culture and the Asian culture that bound the API community together for generations. The Chinese American librarians have been a major component of API librarians and their association -- Chinese American Librarians Association (CALA is one of the most active ones among U.S. minority librarians associations. Chinese American librarians worked in all areas of library profession, especially in the technical services and Asian Studies libraries. The representation of Chinese American librarians working in the management category has been below the national average, which was a common phenomenon among Asian American educators in general.

    2012-01-01

    Hydraulic cements are the binders in concrete and most mortars and stuccos. Concrete, particularly the reinforced variety, is the most versatile of all construction materials, and most of the hydraulic cement produced worldwide is portland cement or similar cements that have portland cement as a basis, such as blended cements and masonry cements. Cement typically makes up less than 15 percent of the concrete mix; most of the rest is aggregates. Not counting the weight of reinforcing media, 1 ton of cement will typically yield about 8 tons of concrete.

    Wu, Lin; Mi, Misa

    2013-01-01

    With biomedical information widely accessible from anywhere at any time, health sciences libraries have become less centralized, and they are challenged to stay relevant and vital to the mission and strategic goals of their home institution. One solution is to embed librarians at strategic points in health professions' education, research, and patient care. This article discusses a proposed five-level model of embedded librarianship within the context of health sciences libraries and describes different roles, knowledge, and skills desirable for health sciences librarians working as embedded librarians.

    2011-01-01

    While the role of the librarian as an expert searcher in the systematic review process is widely recognized, librarians also can be enlisted to help systematic review teams with other challenges. This article reviews the contributions of librarians to systematic reviews, including communicating methods of the review process, collaboratively formulating the research question and exclusion criteria, formulating the search strategy on a variety of databases, documenting the searches, record keeping, and writing the search methodology. It also discusses challenges encountered such as irregular timelines, providing education, communication, and learning new technologies for record keeping. Rewards include building relationships with researchers, expanding professional expertise, and receiving recognition for contributions to health care outcomes.

    This paper describes the cement and concrete industry, and provides data on energy use and carbon dioxide emissions. The potential impact of an energy tax on the industry is briefly assessed. Opportunities identified for reducing carbon dioxide emissions include improved energy efficiency, alternative fuels, and alternative materials. The key factor in determining CO{sub 2} emissions is the level of domestic production. The projected improvement in energy efficiency and the relatively slow growth in domestic shipments indicate that CO{sub 2} emissions in 2000 should be about 5% above the 1990 target. However, due to the cyclical nature of cement demand, emissions will probably be above target levels during peak demand and below target levels during demand troughs. 7 figs., 2 tabs.

    The technology of manufacturing barium aluminate cement from barium sulfate and alumina, using a rotary kiln for firing the clinker is described. The method of granulation of the homogenized charge was used. Conditions of using the ''to mud'' method in industry were indicated. The physical and chemical properties of barium aluminate cement are determined and the quality of several batches of cement prepared on a semi-industrial scale and their suitability for making highly refractory concretes are tested. The optimal composition of the concretes is determined as a function of the mixing water and barium aluminate cement contents. Several experimental batches of concretes were used in the linings of furnaces in the steel industry. The suitability of these cements for use in fields other than steelmaking is examined. It is established that calcium aluminate cement has certain limited applications [fr

    2017-03-01

    Full Text Available The purpose of this study is to investigate awareness of librarian’s job prospects, and to do this a survey was conducted with 502 college students in 14 Departments of Library and Information Science around Korea and 753 librarians in libraries and related agencies. The study results are as follows. First, satisfaction with educational curriculum was higher in students than librarians. Second, both students and librarians regarded workplace based practical training as employment requirements and also evaluated certifications and academic performance as important requirements. Third, both groups asked that information on employment rates be available in a timely manner, and perceived that the librarian’s job prospects were not bright. Therefore, in order to improve employment of librarians, it will be necessary to establish a job information system, reorganize the current educational curriculum into a practice-oriented curriculum, and introduce the national curriculum statements (NCS-based curriculum.

    2010-01-01

    Embedded librarianship gives librarians a prime opportunity to have a direct, positive impact in a clinical setting, classroom setting, or within a working group by providing integrated services that cater to the group's needs. Extending embedded librarian services beyond the various physical settings and into online classrooms is an exceptional way for librarians to engage online learners. This group of students is growing rapidly in numbers and could benefit greatly from having library services and resources incorporated into their classes. The author's services as an embedded librarian in fully online courses at a medium-sized university will be discussed, as will strategies, lessons learned, and opportunities for engaging in this realm. To develop a foundation of knowledge on embedded librarianship, an overview of this topic is provided.

  6. Borgesian Libraries and Librarians in Television Popular Culture

    Directory of Open Access Journals (Sweden)

    Iana Konstantinova

    2013-01-01

    Full Text Available In the works of Jorge Luis Borges, the library appears frequently as a metaphor representative of life and its secrets. It becomes a metaphysical location, posing questions about the nature of time, life, and the universe itself. The librarian becomes a metaphysical figure, leading the search for answers to life’s questions. This article examines the way in which the Borgesian library metaphor has crossed over from the realm of literature into the realm of popular television. By examining two episodes of the BBC series Doctor Who , the TNT franchise The Librarian , and several episodes of Joss Whedon’s cult television series Buffy the Vampire Slayer , it demonstrates that the metaphysical questions posed by the library and its librarian in Borges’s short stories are quite similar to the metaphysical questions posed by the library and its librarians in popular television, demonstrating that the Borgesian library has crossed over into the realms of popular culture.

    Mitchell, R.J.; Stone, D.M.

    1987-01-01

    Mining with backfill has been the subject of several international meetings in recent years and a considerable research effort is being applied to improve both mining economics and ore recovery by using backfill for ground support. Classified mill tailings sands are the most commonly used backfill material but these fine sands must be stabilized before full ore pillar recovery can be achieved. Normal portland cement is generally used for stabilization but the high cost of cement prohibits high cement usage. This paper considers the use of reinforcements in cemented fill to reduce the cement usage. It is concluded that strong cemented layers at typical spacings of about 3 meters in a low cement content bulk fill can reinforce the fill and reduce the overall cement usage. Fibre reinforcements introduced into strong layers or into bulk fills are also known to be effective in reducing cement usage. Some development work is needed to produce the ideal type of anchored fibre in order to realize economic gains from fibre-reinforced fills

  18. Roles for librarians in systematic reviews: a scoping review

    Science.gov (United States)

    Spencer, Angela J.; Eldredge, Jonathan D.

    2018-01-01

    Objective What roles do librarians and information professionals play in conducting systematic reviews? Librarians are increasingly called upon to be involved in systematic reviews, but no study has considered all the roles librarians can perform. This inventory of existing and emerging roles aids in defining librarians’ systematic reviews services. Methods For this scoping review, the authors conducted controlled vocabulary and text-word searches in the PubMed; Library, Information Science & Technology Abstracts; and CINAHL databases. We separately searched for articles published in the Journal of the European Association for Health Information and Libraries, Evidence Based Library and Information Practice, the Journal of the Canadian Heath Libraries Association, and Hypothesis. We also text-word searched Medical Library Association annual meeting poster and paper abstracts. Results We identified 18 different roles filled by librarians and other information professionals in conducting systematic reviews from 310 different articles, book chapters, and presented papers and posters. Some roles were well known such as searching, source selection, and teaching. Other less documented roles included planning, question formulation, and peer review. We summarize these different roles and provide an accompanying bibliography of references for in-depth descriptions of these roles. Conclusion Librarians play central roles in systematic review teams, including roles that go beyond searching. This scoping review should encourage librarians who are fulfilling roles that are not captured here to document their roles in journal articles and poster and paper presentations. PMID:29339933

  19. Training Librarians for 21st Century Repository Services: Emerging Trends

    Directory of Open Access Journals (Sweden)

    Helen Emasealu

    2016-05-01

    Full Text Available The paper reviewed the emerging roles of the 21st century librarians, charged with the responsibility to manage repository services across libraries in present-day information technology environment. Librarians need to be trained and empowered with requisite skills and knowledge needed for successful management of the ICT driven repository initiatives that the 21st century demands. Literature was reviewed on the roles and responsibilities of librarians, training needs and opportunities, career path and recruitment of librarians, and community support necessary for effective and efficient implementation and management of repository initiatives. This entails the ability to comprehend trends and change patterns which are essential for providing research focused and user-friendly models in open repository services that are based on thorough analytical understanding of the challenges of emerging trends. To achieve this requires the training and retraining of librarians to reposition them as information specialists in their career path. The role of the library as an integral part of its social environment is to educate the community about the existence of an open repository by building partnership with community-oriented research centres through seminars, workshops, symposium, training, and awareness programmes. The study recommends that librarians should strategize and collaborate with researchers to make open repository an essential research tool.

Journal of the Medical Library Association, 105(2, 120-131. http://dx.doi.org/10.5195/jmla.2017.201 Abstract Objective – To determine the effects of the professional designation and communication method on clinical, educational, and research activities and related users’ reported satisfaction with and perceived quality of a librarian-mediated literature searching service. Design – Online survey. Setting – A large teaching hospital in Ontario, Canada. Subjects – 237 health sciences centre staff who were requesting librarian-mediated literature searching over a one-year period. Methods – From February 1, 2014 to January 31, 2015, one-third of the health centre staff members requesting searching services, representing a systematic sample of the user group, were invited to participate in the survey. The survey centred on questioning participants on a critical incident, which, according to the critical incident technique, is an actual event upon which recollections are made, rather than hypothetical situations. In the case of this study, the critical incident was the service they received upon requesting literature searching by a librarian who was blinded concerning the originator of the request. With a 71% response rate, the researchers received 137 responses to the survey by health sciences staff. Participants were asked how many literature searches they had requested in the previous year, the reason they requested the service, how they submitted the request, and whether the librarian followed up for further clarification of their need. They also reported on the relevance of the results and their method of delivery, along with their perceptions of the overall quality of the service. Main Results – The results came from 137 completed surveys, for a 71% response

    2009-10-01

    By the mid 2000s, reports of hospital librarians losing jobs and hospital libraries closing were rife. In 2005, Vital Pathways: The Hospital Libraries Project was established by 2005/06 MLA President M.J. Tooey, AHIP, FMLA, to assess the truth of these reports and to study and develop strategies to support hospital librarians. Throughout this long-term project, opportunities were sought to understand the issues more clearly. A steering committee, along with three task forces, was established to carry out the work of the project. The steering committee provided oversight and had responsibility for promoting and marketing the project. The three task forces were responsible for conducting a survey on the status of hospital librarians, determining the involvement of librarians in medical education and accreditation, and researching and writing a document reviewing current and future roles for hospital librarians. Along the way, these responsibilities grew and evolved. After a little more than three years, the Task Force on Vital Pathways for Hospital Librarians Steering Committee presented a final report regarding its accomplishments to the MLA Board of Directors. A sampling of these accomplishments includes the status of hospital librarians survey, a website, a position document with an accompanying executive summary, a short promotional brochure, and a final culminating activity, this symposium. Although these are difficult times for all libraries, hospital librarians and libraries seem particularly affected. In a competitive health care environment that is driven by the bottom line, influenced by real estate hunger, and affected by the belief of hospital administrators that access to health information comes from the Internet and is free, the hospital librarian seems doomed. However, even in these difficult times, there are hospital librarians who are not only surviving, but thriving. Is it because they are entrepreneurial? Opportunistic? Innovative? Flexible? All

    2004-01-01

    ven in the 21st century, millions of people are working daily in a dusty environment. They are exposed to different types of health hazards such as fume, gases and dust, which are risk factors in developing occupational disease. Cement industry is involved in the development of structure of this advanced and modern world but generates dust during its production. Cement dust causes lung function impairment, chronic obstructive lung disease, restrictive lung disease, pneumoconiosis and carcinoma of the lungs, stomach and colon. Other studies have shown that cement dust may enter into the systemic circulation and thereby reach the essentially all the organs of body and affects the different tissues including heart, liver, spleen, bone, muscles and hairs and ultimately affecting their micro-structure and physiological performance. Most of the studies have been previously attempted to evaluate the effects of cement dust exposure on the basis of spirometry or radiology, or both. However, collective effort describing the general effects of cement dust on different organ and systems in humans or animals, or both has not been published. Therefore, the aim of this review is to gather the potential toxic effects of cement dust and to minimize the health risks in cement mill workers by providing them with information regarding the hazards of cement dust.

    This paper describes a corrosion resistant cemented carbide composite. It comprises: a granular tungsten carbide phase, a semi-continuous solid solution carbide phase extending closely adjacent at least a portion of the grains of tungsten carbide for enhancing corrosion resistance, and a substantially continuous metal binder phase. The cemented carbide composite consisting essentially of an effective amount of an anti-corrosion additive, from about 4 to about 16 percent by weight metal binder phase, and with the remaining portion being from about 84 to about 96 percent by weight metal carbide wherein the metal carbide consists essentially of from about 4 to about 30 percent by weight of a transition metal carbide or mixtures thereof selected from Group IVB and of the Periodic Table of Elements and from about 70 to about 96 percent tungsten carbide. The metal binder phase consists essentially of nickel and from about 10 to about 25 percent by weight chromium, the effective amount of an anti-corrosion additive being selected from the group consisting essentially of copper, silver, tine and combinations thereof

  11. Formalized Curiosity: Reflecting on the Librarian Practitioner-Researcher

    Directory of Open Access Journals (Sweden)

    Full Text Available There’s a well-documented gap between research and practice. A Google search for scholarly articles using the term “research practice gap” yields 2,530 hits as of this writing, while a search using the discovery layer at the University Library, University of Saskatchewan, for the same search termsyields 1,038 hits. There are a large number of articles which explore bridging the research/practice gap. So what will fill that gap in librarianship? Partnerships between LIS scholars and librarians have been suggested,and this can certainly help to mitigate the research/practice gap. Each group has things that the other group needs. Practitioners often have funding barriers, a real or perceived lack of research skills, and uneven access to the research literature. Scholars have less access to certain data that can only be obtained from practice situations, and a partnership with library practitioners can provide greater access to real life locations, users, and situations. As well, a partnership can help ensure that what the scholars are researching is relevant to the practitioners. However, scholar/practitioner partnerships sometimes are not practical, even in our age of social networking. In Canada, forexample, there is a dearth of library schools to cover our vast physical space. Physical proximity can play a role in whether or not a partnership is successful. Timeliness also is a factor. Practitioners sometimes need to “hit the ground running" and get their research done in order to inform practice. The logistics of a partnership can be time-consuming. As well, I am estimating that there are far more library and information professionals than there are university library scholars, so it’s really up to us to fill that gap ourselves in many cases.

    This study describes the current state of Canadian university health sciences librarians' knowledge about, training needs for, and barriers to participating in systematic reviews (SRs). A convenience sample of Canadian librarians was surveyed. Over half of the librarians who had participated in SRs acknowledged participating in a traditional librarian role (e.g., search strategy developer); less than half indicated participating in any one nontraditional librarian role (e.g., data extractor). Lack of time and insufficient training were the most frequently reported barriers to participating in SRs. The findings provide a benchmark for tracking changes in Canadian university health sciences librarians' participation in SRs. PMID:25918485

    Work as a librarian involves exposure to potential risk factors for developing upper limb disorders. The prevalence of upper limb symptoms has, however, not previously been assessed in this occupational group. To estimate the 7-day and annual prevalence of self-reported neck and upper limb symptoms in librarians and to examine associations with specific tasks and ergonomic risk factors. A cross-sectional study using components of the standardized Nordic questionnaire. The study population consisted of librarians employed by a large local authority, and data collection was by means of a self-administered questionnaire. from studies on keyboard workers and on the general population were used as comparators. The 7-day prevalence of self-reported neck and upper limb pain in female librarians was 42% (95% confidence interval (CI) 33.7-50.5) and the annual prevalence was 65% (95% CI 56.6-72.8). The prevalence of reported wrist and hand pain increased with increased working involving a wide thumb-index span (P librarians was high, but there was insufficient evidence to confirm whether the prevalence was higher than in the general population or among keyboard workers. Working with a wide thumb-index span was associated with reporting upper limb symptoms.

    2008-01-01

    In this study, a cement based syntactic foam core was proposed and experimentally investigated for composite sandwich structures. This was a multi-phase composite material with microballoon dispersed in a rubber latex toughened cement paste matrix. A trace amount of microfiber was also incorporated to increase the number of mechanisms for energy absorption and a small amount of nanoclay was added to improve the crystal structure of the hydrates. Three groups of cement based syntactic foams with varying cement content were investigated. A fourth group of specimens containing pure cement paste were also prepared as control. Each group contained 24 beam specimens. The total number of beam specimens was 96. The dimension of each beam was 30.5 cm x 5.1 cm x 1.5 cm. Twelve foam specimens from each group were wrapped with plain woven 7715 style glass fabric reinforced epoxy to prepare sandwich beams. Twelve cubic foam specimens, three from each group, with a side length of 5.1 cm, were also prepared. Three types of testing, low velocity impact test and four-point bending test on the beam specimens and compression test on the cubic specimens, were conducted to evaluate the impact energy dissipation, stress-strain behavior, and residual strength. Scanning electron microscope (SEM) was also used to examine the energy dissipation mechanisms in the micro-length scale. It was found that the cement based syntactic foam has a higher capacity for dissipating impact energy with an insignificant reduction in strength as compared to the control cement paste core. When compared to a polymer based foam core having similar compositions, it was found that the cement based foam has a comparable energy dissipation capacity. The developed cement based syntactic foam would be a viable alternative for core materials in impact-tolerant composite sandwich structures

    Cement selection can be confusing because factors such as substrate, the type of restoration, and patient needs must be considered. Some substrates require additional treatment before cementation. This article describes the most commonly used traditional crown and bridge cements (GI and RMGI) used for metal and metal-ceramic restorations, and resin cements used for all-ceramic restorations. Advantages, disadvantages, indications, and contraindications of cements have been reviewed. Recommended uses of cements for metal, ceramic, and laboratory composite restorations have been presented. General guidelines for surface treatment ot silica- and zirconia-based restorations when using resin cements have been discussed.

    The performance of cement-based matrices intended for radwaste immobilization is assessed. The long-term performance of the matrix is characterized by thermodynamic evaluation of experimental data. The results are presented in a general form, amenable to a range of specific formulations. The interaction of specific radwaste components with cements has been studied, using Iodine as an example. It occurs as both I - and IO 3 - species, but these differ sharply in sorption characteristics. The effect of ionizing radiation of the pH and E h of cement matrices is reported. (author)

  20. Cements in Radioactive Waste Disposal

    International Nuclear Information System (INIS)

    Glasser, F.P.

    2013-01-01

    The use of cement and concrete to immobilise radioactive waste is complicated by the wide- ranging nature of inorganic cementing agents available as well as the range of service environments in which cement is used and the different functions expected of cement. For example, Portland cement based concretes are widely used as structural materials for construction of vaults and tunnels. These constructions may experience a long pre-closure performance lifetime during which they are required to protect against collapse and ingress of water: strength and impermeability are key desirable characteristics. On the other hand, cement and concrete may be used to form backfills, ranging in permeability. Permeable formulations allow gas readily to escape, while impermeable barriers retard radionuclide transport and reduce access of ground water to the waste. A key feature of cements is that, while fresh, they pass through a fluid phase and can be formed into any shape desired or used to infiltrate other materials thereby enclosing them into a sealed matrix. Thereafter, setting and hardening is automatic and irreversible. Where concrete is used to form structural elements, it is also natural to use cement in other applications as it minimises potential for materials incompatibility. Thus cement- mainly Portland cement- has been widely used as an encapsulant for storage, transport and as a radiation shield for active wastes. Also, to form and stabilise structures such as vaults and silos. Relative to other potential matrices, cement also has a chemical immobilisation potential, reacting with and binding with many radionuclides. The chemical potential of cements is essentially sacrificial, thus limiting their performance lifetime. However performance may also be required in the civil engineering sense, where strength is important, so many factors, including a geochemical description of service conditions, may require to be assessed in order to predict performance lifetime.

    How can an embedded research informationist add value to the scientific output of research teams? The University of California-Los Angeles (UCLA) Louise M. Darling Biomedical Library is an academic health sciences library serving the clinical, educational, and research needs of the UCLA community. A grant from the National Library of Medicine funded a librarian to join a UCLA research team as an informationist. The informationist meets regularly with the research team and provides guidance related to data management, preservation, and other information-related issues. Early results suggest that the informationist's involvement has influenced the team's data gathering, storage, and curation methods. The UCLA Library has also changed the librarian's title to research informationist to reflect the new activities that she performs. The research informationist role provides an opportunity for librarians to become effective members of research teams and improve research output.

    2016-11-01

    Full Text Available Objective: This study investigated responsibilities, skill sets, degrees, and certifications required of health care navigators in order to identify areas of potential overlap with health sciences librarianship. Method: The authors conducted a content analysis of health care navigator position announcements and developed and assigned forty-eight category terms to represent the sample’s responsibilities and skill sets. Results: Coordination of patient care and a bachelor’s degree were the most common responsibility and degree requirements, respectively. Results also suggest that managing and providing health information resources is an area of overlap between health care navigators and health sciences librarians, and that librarians are well suited to serve on navigation teams. Conclusion: Such overlap may provide an avenue for collaboration between navigators and health sciences librarians.

    Graphs are about connections, and are an important part of our connected and data-driven world. A Librarian's Guide to Graphs, Data and the Semantic Web is geared toward library and information science professionals, including librarians, software developers and information systems architects who want to understand the fundamentals of graph theory, how it is used to represent and explore data, and how it relates to the semantic web. This title provides a firm grounding in the field at a level suitable for a broad audience, with an emphasis on open source solutions and what problems these tools solve at a conceptual level, with minimal emphasis on algorithms or mathematics. The text will also be of special interest to data science librarians and data professionals, since it introduces many graph theory concepts by exploring data-driven networks from various scientific disciplines. The first two chapters consider graphs in theory and the science of networks, before the following chapters cover networks in vario...

  6. Roles for librarians in systematic reviews: a scoping review

    2018-01-01

    Results: We identified 18 different roles filled by librarians and other information professionals in conducting systematic reviews from 310 different articles, book chapters, and presented papers and posters. Some roles were well known such as searching, source selection, and teaching. Other less documented roles included planning, question formulation, and peer review. We summarize these different roles and provide an accompanying bibliography of references for in-depth descriptions of these roles. Conclusion: Librarians play central roles in systematic review teams, including roles that go beyond searching. This scoping review should encourage librarians who are fulfilling roles that are not captured here to document their roles in journal articles and poster and paper presentations.  This article has been approved for the Medical Library Association’s Independent Reading Program.

  15. Calcium Aluminate Cement Hydration Model

    Directory of Open Access Journals (Sweden)

    Matusinović, T.

    2011-01-01

    Full Text Available Calcium aluminate cement (AC is a very versatile special cement used for specific applications. As the hydration of AC is highly temperature dependent, yielding structurally different hydration products that continuously alter material properties, a good knowledge of thermal properties at early stages of hydration is essential. The kinetics of AC hydration is a complex process and the use of single mechanisms models cannot describe the rate of hydration during the whole stage.This paper examines the influence of temperature (ϑ=5–20 °C and water-to-cement mass ratio (mH /mAC = 0.4; 0.5 and 1.0 on hydration of commercial iron-rich AC ISTRA 40 (producer: Istra Cement, Pula, Croatia, which is a part of CALUCEM group, Figs 1–3. The flow rate of heat generation of cement pastes as a result of the hydration reactions was measured with differential microcalorimeter. Chemically bonded water in the hydrated cement samples was determined by thermo-gravimetry.Far less heat is liberated when cement and water come in contact for the first time, Fig. 1, than in the case for portland cement (PC. Higher water-to-cement ratio increases the heat evolved at later ages (Fig. 3 due to higher quantity of water available for hydration. A significant effect of the water-to-cement ratio on the hydration rate and hydration degree showed the importance of water as being the limiting reactant that slows down the reaction early. A simplified stoichiometric model of early age AC hydration (eq. (8 based on reaction schemes of principal minerals, nominally CA, C12A7 and C4AF (Table 1, was employed. Hydration kinetics after the induction period (ϑ < 20 °C had been successfully described (Fig. 4 and Table 2 by a proposed model (eq.

    2013-01-01

    In recent years, the use of vertebral cementing techniques for vertebroplasty and kyphoplasty has spread for the treatment of pain associated with osteoporotic vertebral compression fractures. This is also associated with the increased incidence of complications related with these procedures, the most frequent being originated by leakage of cementation material. Cement can escape into the vertebral venous system and reach the pulmonary circulation through the azygous system and cava vein, producing a cement embolism. This is a frequent complication, occurring in up to 26% of patients undergoing vertebroplasty but, since most patients have no clinical or hemodynamical repercussion, this event usually goes unnoticed. However, some serious, and even fatal cases, have been reported. We report the case of a 74-year-old male patient who underwent vertebroplasty for persistent pain associated with osteoporotic L3 vertebral fracture and who developed a cement leak into the cava vein and right pulmonary artery during the procedure. Although he developed a pulmonary cement embolism, the patient remained asymptomatic and did not present complications during follow-up. Copyright © 2012 Elsevier España, S.L. All rights reserved.

  18. Calcium Orthophosphate Cements and Concretes

    Sergey V. Dorozhkin

    2009-03-01

    Full Text Available In early 1980s, researchers discovered self-setting calcium orthophosphate cements, which are a bioactive and biodegradable grafting material in the form of a powder and a liquid. Both phases form after mixing a viscous paste that after being implanted, sets and hardens within the body as either a non-stoichiometric calcium deficient hydroxyapatite (CDHA or brushite, sometimes blended with unreacted particles and other phases. As both CDHA and brushite are remarkably biocompartible and bioresorbable (therefore, in vivo they can be replaced with newly forming bone, calcium orthophosphate cements represent a good correction technique for non-weight-bearing bone fractures or defects and appear to be very promising materials for bone grafting applications. Besides, these cements possess an excellent osteoconductivity, molding capabilities and easy manipulation. Furthermore, reinforced cement formulations are available, which in a certain sense might be described as calcium orthophosphate concretes. The concepts established by calcium orthophosphate cement pioneers in the early 1980s were used as a platform to initiate a new generation of bone substitute materials for commercialization. Since then, advances have been made in the composition, performance and manufacturing; several beneficial formulations have already been introduced as a result. Many other compositions are in experimental stages. In this review, an insight into calcium orthophosphate cements and concretes, as excellent biomaterials suitable for both dental and bone grafting application, has been provided.

  20. Low pH Cements

    International Nuclear Information System (INIS)

    Savage, David; Benbow, Steven

    2007-05-01

    The development of low-pH cements for use in geological repositories for radioactive waste stems from concerns over the potential for deleterious effects upon the host rock and other EBS materials (notably bentonite) under the hyperalkaline conditions (pH > 12) of cement pore fluids. Low pH cement (also known as low heat cement) was developed by the cement industry for use where large masses of cement (e.g. dams) could cause problems regarding heat generated during curing. In low pH cements, the amount of cement is reduced by substitution of materials such as fly ash, blast furnace slag, silica fume, and/or non-pozzolanic silica flour. SKB and Posiva have ruled out the use of blast furnace slag and fly-ash and are focusing on silica fume as a blending agent. Currently, no preferred composition has been identified by these agencies. SKB and Posiva have defined a pH limit ≤ 11 for cement grout leachates. To attain this pH, blending agents must comprise at least 50 wt % of dry materials. Because low pH cement has little, or no free portlandite, the cement consists predominantly of calcium silicate hydrate (CSH) gel with a Ca/Si ratio ≤ 0.8. Although there are potential implications for the performance of the spent fuel and cladding due to the presence of hyperalkaline fluids from cement, the principal focus for safety assessment lies with the behaviour of bentonite. There are a number of potential constraints on the interaction of hyperalkaline cement pore fluids with bentonite, including mass balance, thermodynamic issues, mass transport, and kinetics, but none of these is likely to be limiting if conventional OPC cements are employed in repository construction. Nevertheless: Low-pH cements may supply approximately 50 % less hydroxyl ions than conventional OPC for a given volume of cement, but mass balance constraints are complicated by the uncertainty concerning the type of secondary minerals produced during cement-bentonite interaction. The change of aqueous

    The development of low-pH cements for use in geological repositories for radioactive waste stems from concerns over the potential for deleterious effects upon the host rock and other EBS materials (notably bentonite) under the hyperalkaline conditions (pH > 12) of cement pore fluids. Low pH cement (also known as low heat cement) was developed by the cement industry for use where large masses of cement (e.g. dams) could cause problems regarding heat generated during curing. In low pH cements, the amount of cement is reduced by substitution of materials such as fly ash, blast furnace slag, silica fume, and/or non-pozzolanic silica flour. SKB and Posiva have ruled out the use of blast furnace slag and fly-ash and are focusing on silica fume as a blending agent. Currently, no preferred composition has been identified by these agencies. SKB and Posiva have defined a pH limit {<=} 11 for cement grout leachates. To attain this pH, blending agents must comprise at least 50 wt % of dry materials. Because low pH cement has little, or no free portlandite, the cement consists predominantly of calcium silicate hydrate (CSH) gel with a Ca/Si ratio {<=} 0.8. Although there are potential implications for the performance of the spent fuel and cladding due to the presence of hyperalkaline fluids from cement, the principal focus for safety assessment lies with the behaviour of bentonite. There are a number of potential constraints on the interaction of hyperalkaline cement pore fluids with bentonite, including mass balance, thermodynamic issues, mass transport, and kinetics, but none of these is likely to be limiting if conventional OPC cements are employed in repository construction. Nevertheless: Low-pH cements may supply approximately 50 % less hydroxyl ions than conventional OPC for a given volume of cement, but mass balance constraints are complicated by the uncertainty concerning the type of secondary minerals produced during cement-bentonite interaction.

    1997-01-01

    Inorganic admixtures to enhance the fluidity of cement material was developed. These admixtures turned into easy to immobilize the miscellaneous radioactive waste using cement material. It was found that the ζ potential of cement particles was directly proportional to the content of the inorganic admixtures in cement paste and the particles of cement were dispersed at the high ζ potential. The condensed sodium phosphate, which was the main component of the inorganic admixtures, retarded the dissolution of Ca 2+ ion from the cement, and generated the colloids by incorporating dissolved Ca 2+ ion. The cement material containing the inorganic admixtures was found to have the same mechanical strength and adsorption potential of radionuclides in comparison to normal cement materials. It was confirmed that the cement material containing the inorganic admixture was effectively filled gaps of miscellaneous radioactive waste. (author)

    Wu, Zichao

    2000-10-01

    This thesis presents the development of high-performance blended cements from industrial by-products. To overcome the low-early strength of blended cements, several chemicals were studied as the activators for cement hydration. Sodium sulfate was discovered as the best activator. The blending proportions were optimized by Taguchi experimental design. The optimized blended cements containing up to 80% fly ash performed better than Type I cement in strength development and durability. Maintaining a constant cement content, concrete produced from the optimized blended cements had equal or higher strength and higher durability than that produced from Type I cement alone. The key for the activation mechanism was the reaction between added SO4 2- and Ca2+ dissolved from cement hydration products.

    2006-10-01

    This paper describes a survey-based evaluation of the five-year old Liaison Librarian Program at the University of Florida. Liaison librarians, faculty, students, staff, residents, and post-doctoral associates were queried via Web-based surveys. Questions addressed client and liaison perspectives on a variety of issues, including program and service awareness and usage, client-library relations and communication, client support for the program, and liaison workload. Approximately 43% of the 323 client respondents were aware of liaison services; 72% (n = 163) of these clients had had contact with their liaison. Ninety-five percent (n = 101) of faculty and students who reported contact with their liaison supported the continuation of the program. Liaison services were used by a greater percentage of faculty than students, although they had similar patterns of usage and reported the same "traditional" services to be most important. Liaisons indicated that communications with clients had increased, the reputation of the library was enhanced, and their workloads had increased as a result of the Liaison Librarian Program. Survey results suggest that the Liaison Librarian Program has a core set of clients who use and highly value the services provided by liaisons. Recommendations addressing workload, training, marketing, and administrative support are provided.

    Lynn, Valerie A; Bose, Arpita; Boehmer, Susan J

    2010-01-01

    Attending professional continuing education (CE) is an important component of librarianship. This research study identified librarians' preferences in delivery modalities of instruction for professional CE. The study also identified influential factors associated with attending CE classes. Five instruction-delivery modalities and six influential factors were identified for inclusion in an online survey. The survey completed by members of the American Library Association (ALA), Special Libraries Association (SLA), and Medical Library Association (MLA) provided the data for analysis of librarian preferences and influential factors. The majority of respondents were MLA members, followed by ALA and SLA members. Librarians from all three library associations preferred the face-to-face instructional modality. The most influential factor associated with the decision to attend a professional CE class was cost. All five instruction-delivery modalities present useful structures for imparting professional CE. As librarians' experience with different modalities increases and as technology improves, preferences in instruction delivery may shift. But at present, face-to-face remains the most preferred modality. Based on the results of this study, cost was the most influential factor associated with attending a CE class. This may change as additional influential factors are identified and analyzed in future studies.

  5. Roles for Information professionals in patient education: Librarians' perspective

    2010-07-01

    Full Text Available Through an examination of librarians’ contributions to the PEPTalk research project, this article highlights roles for information professionals at various stages in the design and clinical implementation of an information system that delivers patient education. The Personal Education Plan (PEPTalk was a collaborative, multi-disciplinary research project (2005-2006 based at the University Health Network’s Princess Margaret Hospital that designed an information system to provide web-based health information resources to both patients and clinicians under a shared umbrella of patient education. This article provides an overview of the PEPTalk project methods and outcomes, and documents the contributions of librarians throughout the design and clinical implementation stages of the project. Librarians brought expertise about information seeking behaviours of both patients and clinicians to the project; liaised across institutional and professional boundaries; developed a classification system for online learning objects, and educated project team about information and health literacies. The contributions of librarians on the PEPTalk project illustrate the need for boundary spanners, information brokers, knowledge translators, and change champions in the design and implementation of patient education delivery systems. There are new roles emergent at the intersections of clinical practice and health information provision. There is a need for the traditional skills and expertise of librarians and other information professionals in tailoring health information. Yet the design and implementation of patient education systems also require the development of new skills and the application of advanced information literacy as it pertains to both clinicians and patients.

    Directory of Open Access Journals (Sweden)

    Emilie Regina Algenio

    2018-02-01

    Full Text Available The corpus of academic librarianship literature notes very little material in relation to the work of new copyright librarians. However, the number of academic libraries hiring librarians to fill these positions is increasing, and the need for such literature is real and pertinent. The purpose of this research is to assist incoming copyright librarians with practical, evidence-based guidance for colleagues just starting out in roles focused on copyright issues. The author drew from professional experience as a first-time copyright librarian at a Carnegie One academic institution in the United States.

  13. Polymer-cement interactions towards improved wellbore cement fracture sealants

    Science.gov (United States)

    Beckingham, B. S.; Iloejesi, C.; Minkler, M. J.; Schindler, A. K.; Beckingham, L. E.

    2017-12-01

    Carbon capture, utilization, and storage (CCUS) in deep geologic formations is a promising means of reducing point source emissions of CO2. In these systems, CO2 is captured at the source and then injected to be utilized (eg. in enhanced oil recovery or as a working fluid in enhanced geothermal energy plants) or stored in geologic formations such as depleted oil and gas reservoirs or saline aquifers. While CCUS in subsurface systems could aid in reducing atmospheric CO2 emissions, the potential for CO2 leakage from these systems to overlying formations remains a major limitation and poses a significant risk to the security of injected CO2. Thus, improved materials for both initial wellbore isolation and repairing leakage pathways that develop over time are sought. One approach for the repair of cement fractures in wellbore (and other) systems is the injection of polymer materials into the fracture with a subsequent environmentally dependent (temperature, pressure, pH, etc.) densification or solidification. Here, we aim to investigate novel polymer materials for use to repair leaking wellbores in the context of CCUS. We synthesize and fully characterize a series of novel polymer materials and utilize a suite of analysis techniques to examine polymer-cement interactions at a range of conditions (namely temperature, pressure and pH). Initial findings will be leveraged to design novel polymer materials for further evaluation in polymer-cement composite cores, cement fracture healing, and the aging behavior of healed cements.

    2015-01-01

    Higher education is moving to offer more fully online programs, and the health science fields are no different. These programs are either hybrid or completely online. It is up to the health sciences librarian to adapt services offered by the academic library to these types of courses. This column discusses the multiple ways a librarian can be an embedded librarian in a course using a learning management system (LMS). The process of creating a customized embedded librarian program, results, and lessons learned from the different embedded librarian roles are also discussed.

    The Development Plan (CRWMS M andO 1999a) pertaining to this task defines the work scopes and objectives for development of various submodels for the Physical and Chemical Environment Abstraction Model for TSPA-LA. The Development Plan (CRWMS M andO 1999a) for this specific task establishes that an evaluation be performed of the chemical reactions between seepage that has entered the drift and concrete which might be used in the repository emplacement drifts. The Development Plan (CRWMS M andO 1999a) then states that the potential effects of these water/grout reactions on chemical conditions in the drift be assessed factoring in the influence of carbonation and the relatively small amount of grout. This task is also directed at: (1) developing a conceptualization of important cement/seepage interactions and potential impacts on EBS performance, (2) performing a screening analysis to assess the importance of cement/seepage interactions. As the work progresses and evolves on other studies, specifically the Engineered Barrier System: Physical and Chemical Environment (P andCE) Model (in progress), many of the issues associated with items 1 and 2, above, will be assessed. Such issues include: (1) Describing the mineralogy of the specified cementitious grout and its evolution over time. (2) Describing the composition of the water before contacting the grout. (3) Developing reasonable upper-bound estimates for the composition of water contacting grout, emphasizing pH and concentrations for anions such as sulfate. (4) Evaluating the equilibration of cement-influenced water with backfill and gas-phase CO 2 . (5) Developing reasonable-bound estimates for flow rate of affected water into the drift. The concept of estimating an ''upper-bound'' range for reaction between the grout and the seepage, particularly in terms of pH is based on equilibrium being established between the seepage and the grout. For example, this analysis can be based on equilibrium being established as

    Pre-clinical screening of cemented implant systems could be improved by modeling the longer-term response of the implant/cement/bone construct to cyclic loading. We formulated bone cement with degraded fatigue fracture properties (Sub-cement) such that long-term fatigue could be simulated in short-term cadaver tests. Sub-cement was made by adding a chain-transfer agent to standard polymethylmethacrylate (PMMA) cement. This reduced the molecular weight of the inter-bead matrix without changing reaction-rate or handling characteristics. Static mechanical properties were approximately equivalent to normal cement. Over a physiologically reasonable range of stress-intensity factor, fatigue crack propagation rates for Sub-cement were higher by a factor of 25+/-19. When tested in a simplified 2 1/2-D physical model of a stem-cement-bone system, crack growth from the stem was accelerated by a factor of 100. Sub-cement accelerated both crack initiation and growth rate. Sub-cement is now being evaluated in full stem/cement/femur models.

    Science.gov (United States)

    Kelham, Charlotte

    2014-09-01

    Until relatively recently, the concept of information literacy, and teaching the skills to enable it, was mainly a concern of academic libraries. Now, it is also seen to be of high importance within the context of health care libraries. Health care libraries and librarians can provide crucial support towards the implementation of evidence-based practice in patient care through both information literacy skills training and by conducting mediated searches on behalf of health care practitioners. This article reports the findings from an investigation conducted by Charlotte Kelham as part of her MA in Librarianship from the University of Sheffield. Her dissertation investigated how health care librarians understand the concept of information literacy, the implications of this for their role and their perceptions around how their role is valued. Charlotte graduated from Sheffield in 2013 and is currently job hunting. AM. © 2014 The authors. Health Information and Libraries Journal © 2014 Health Libraries Journal.

  11. Information Dissemination: Exploring the Librarian's Role in Public Relations

    Smith, Virginia

    Historically the special librarian's role has been to store and preserve the organization's knowledge. In today's Information Age, increasing importance is placed on information dissemination. The management of electronic resources has been an important aspect of the Gemini librarian's job since the library's inception. In this paper, I discuss the methods that the Gemini Observatory is using to share its resources with a growing audience. Note: The Gemini Observatory is operated by the Association of Universities for Research in Astronomy, Inc., under a cooperative agreement with the NSF on behalf of the Gemini partnership: the National Science Foundation (United States), the Particle Physics and Astronomy Research Council (United Kingdom), the National Research Council (Canada), CONICYT (Chile), the Australian Research Council (Australia), CNPq (Brazil) and CONICET (Argentina).

    Full Text Available MAKNA DIRI ALPHA FEMALE PADA PUSTAKAWAN PEREMPUAN: Membangun Citra Positif Perpustakaan Melalui Kiprah Pustakawan Perempuan Sebagai Alpha Female Abstract The profession of librarians is often associated with women. This can be justified if we refer to data and research results that have been done in several countries. However, many women who work in the library, this does not necessarily describe that library work is a simple and easy job. However, on the contrary, work in the field of library is increasingly complex and demands the competence and mastery of information technology. Moreover, the expectations of some users who demand a fast and quality service. Therefore to answer this problem required a female librarian who has the competence, intelligent and able to become a leader for his group and can show the characteristics as a professional. As for the description of people like this people call it with the term alpha female. With the birth of alpha female figures among female librarians is expected to change the positive image of librarians and library institutions. This is because the female alpha figure in the female librarian is a figure of women who are considered "perfect" are still rare today. Keywords: library, librarian, symbolic interaction, alpha female. Abstrak Profesi pustakawan kerapkali dikaitkan dengan kaum perempuan.

    2015-11-01

    Full Text Available Rutgers University Libraries have recognized the need to expand their current research data services into a well-documented and well-supported service available to the Rutgers research community. In 2005, Rutgers University Libraries created RUcore, Rutgers University Community Repository, which has served as the University’s formal repository for institutional scholarship, special collections, and Electronic Theses & Dissertations. With the impetus of the 2010 NSF directive for research data sharing and preservation, RUcore development was extended to accept research data content. Ingest of pilot data projects began in 2010 via a librarian-mediated process. In order to provide a better defined workflow and mission for research data services, in July 2014, the Rutgers University Librarian organized a Task Force to investigate the evaluation process for technical, legal, and confidential issues involved in research data acceptance, and to establish an administrative and evaluation framework for the deposit of research data. After a review of 35 repositories using 34 criteria, the Task Force drafted a plan for research data acceptance which proposes wide-spread acceptance of mediated data projects, and prepares for future self-deposit in an online interface. This paper will discuss the issues addressed by the Task Force; acknowledging ownership of data through an institutional data policy, preventing exposure of confidential or sensitive data, establishing a reconfigured data team, requirements for storage capacity and funding, creating a workflow which includes collaboration with research offices, and offering guidance for both researchers and librarians working with research data.

    2017-07-01

    The project identified a set of core competencies for librarians who are involved in systematic reviews. A team of seven informationists with broad systematic review experience examined existing systematic review standards, conducted a literature search, and used their own expertise to identify core competencies and skills that are necessary to undertake various roles in systematic review projects. The team identified a total of six competencies for librarian involvement in systematic reviews: "Systematic review foundations," "Process management and communication," "Research methodology," "Comprehensive searching," "Data management," and "Reporting." Within each competency are the associated skills and knowledge pieces (indicators). Competence can be measured using an adaptation of Miller's Pyramid for Clinical Assessment, either through self-assessment or identification of formal assessment instruments. The Systematic Review Competencies Framework provides a standards-based, flexible way for librarians and organizations to identify areas of competence and areas in need of development to build capacity for systematic review integration. The framework can be used to identify or develop appropriate assessment tools and to target skill development opportunities.

  16. E-book usage amongst academic librarians in South Africa

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available The purpose of this study completed in 2010 was to investigate the use of e-books amongst academic librarians; in particular which e-books are available to academic librarians, why they choose this format, what impact e-books have on librarians’ professional practice and what the usage patterns of e-books are amongst academic librarians. A web-based questionnaire was distributed on the LIASA mailing list. The results reflect a more gradual trend towards e-book adoption. There is still a preference for print or a “bit of both” – print and electronic. This is because of the high costs of e-books using the subscription model as the predominant e-book acquisition model and the lack of sufficient e-books in all subject fields. E-books are used for “browsing for information” and are selected for functionalities such as having the ability to search the document, anytime access and automatic citation. Major problems identified with e-books are: the cost of the equipment to read e-book formats; the cost of the e-books, especially if the subscription purchasing model is used; the lack of reliability of the Internet; and the lack of training in the use of e-books.

Against the background of information age, as well special requirements on subject librarian in specialized libraries, focus and difficulties of construction of subject librarian team are analysed, the viewpoint that construction of subject librarian team should be gradual sis proposed, and two kinds of ways will coexist in a long term. Fist, to be competent for the work of subject librarian librarians in-service should be selected to pursue second degree. Second, full-time or part-time professional should be employed to cooperate with librarians, finally, supporting measures of subject librarian team are expatiated, that is to improve the treatment of subject librarian, to establish an effective management mechanism, and to establish a business training system.

    1979-01-01

    In the last couple of decades several cement- and concrete-based composites have come into prominence. Of these, cement-polymer composites, like cement-fibre composites, have been recognised as very promising, and considerable research and development on their properties, fabrication methods and application are in progress. Of the three types of concrete materials which incorporate polymers to form composites, polymer impregnated concrete forms a major development in which hardened concrete is impregnated with a liquid monomer which is subsequently polymerized to form a rigid polymer network in the pores of the parent material. In this first part of the extensive review of the polymer reinforcement of cement systems, the process technology of the various monomer impregnation techniques and the properties of the impregnated composite are assessed critically. It is shown that the high durability and superior performance of polymer impregnated concrete can provide an economic and competitive alternative in in situ strengthening, and in other areas where conventional concrete can only at best provide adequate performance. The review includes a section on radiation-induced polymerization. (author)

    2015-09-01

    Vertebral compression fractures are the most common osteoporotic fractures. Since the introduction of vertebroplasty and screw augmentation, the management of osteoporotic fractures has changed significantly. The biomechanical characteristics of the risk of adjacent fractures and novel treatment modalities for osteoporotic vertebral fractures, including pure cement augmentation by vertebroplasty, and cement augmentation of screws for posterior instrumentation, are explored. Eighteen human osteoporotic lumbar spines (L1-5) adjacent to vertebral bodies after vertebroplasty were tested in a servo-hydraulic machine. As augmentation compounds we used standard cement and a modified low-strength cement. Different anchoring pedicle screws were tested with and without cement augmentation in another cohort of human specimens with a simple pull-out test and a fatigue test that better reflects physiological conditions. Cement augmentation in the osteoporotic spine leads to greater biomechanical stability. However, change in vertebral stiffness resulted in alterations with the risk of adjacent fractures. By using a less firm cement compound, the risk of adjacent fractures is significantly reduced. Both screw augmentation techniques resulted in a significant increase in the withdrawal force compared with the group without cement. Augmentation using perforated screws showed the highest stability in the fatigue test. The augmentation of cement leads to a significant change in the biomechanical properties. Differences in the stability of adjacent vertebral bodies increase the risk of adjacent fractures, which could be mitigated by a modified cement compound with reduced strength. Screws that were specifically designed for cement application displayed greatest stability in the fatigue test.

    1978-10-01

    Leaching of tritium from cement composites into an aqueous phase has been studied to evaluate the safety of incorporation of the tritiated liquid waste into cement. Leaching tests were performed by the method recommended by the International Atomic Energy Agency. The Leaching fraction was measured as functions of waste-cement ratio (Wa/C), temperature of leachant and curing time. The tritium leachability of cement in the long term test follows the order: alumina cement portland cement slag cement. The fraction of tritium leached increases with increasing Wa/C and temperature and decreasing curing period. A deionized water as a leachant gives a slightly higher leachability than synthetic sea water. The amount leached of tritium from a 200 l drum size specimen was estimated on the basis of the above results. (author)

    There are many problems that can arise when drilling into sub-normally pressured or naturally fractured zones. Lost circulation is one problem that is commonly encountered while drilling oil and gas wells. Lost circulation can lead to increased costs associated with drilling due to rig time, spreadsheet costs, and expensive mud system losses. Cement is one of the most effective treatment options, although it is not normally considered the first option because most operators are forced to trip out of the wellbore and utilize a squeeze packer. This is not always a viable option because of potential well control issues associated with the hydrostatic pressure reduction due to the losses of the whole mud. One treatment option that is commonly overlooked is pumping cement slurries through the bottom hole assembly and drill bit. This is generally not attempted for a variety of reasons. These reasons include: I Concern about 'squeezing off' of the cement in the bit II Lack of potential quality control associated with mixing 'on the fly' III Lack of the ability to test the actual mixed slurry samples The use of a pre-mixed, storable cement slurry has eliminated the concerns associated with pumping cement slurries through mud motors, MWD tools, BHA's, and drill bits. This advanced cement technology has been successfully utilized while reducing the risks associated with these lost circulation treatments. In addition, this technology has eliminated the costs associated with using a squeeze packer and the rig time required for several trips out of the wellbore. The paper will describe the premixed slurry properties and QA/QC procedures that are required for successful through the bit operations. This paper will also provide case histories of successful through the bit operation, as well as background information leading to the treatments. The case histories include successful through the bit remediation of severe lost circulation zones and as well the

  6. Synthesis of Portland cement and calcium sulfoaluminate-belite cement for sustainable development and performance

    Science.gov (United States)

    Chen, Irvin Allen

    Portland cement concrete, the most widely used manufactured material in the world, is made primarily from water, mineral aggregates, and portland cement. The production of portland cement is energy intensive, accounting for 2% of primary energy consumption and 5% of industrial energy consumption globally. Moreover, portland cement manufacturing contributes significantly to greenhouse gases and accounts for 5% of the global CO2 emissions resulting from human activity. The primary objective of this research was to explore methods of reducing the environmental impact of cement production while maintaining or improving current performance standards. Two approaches were taken, (1) incorporation of waste materials in portland cement synthesis, and (2) optimization of an alternative environmental friendly binder, calcium sulfoaluminate-belite cement. These approaches can lead to less energy consumption, less emission of CO2, and more reuse of industrial waste materials for cement manufacturing. In the portland cement part of the research, portland cement clinkers conforming to the compositional specifications in ASTM C 150 for Type I cement were successfully synthesized from reagent-grade chemicals with 0% to 40% fly ash and 0% to 60% slag incorporation (with 10% intervals), 72.5% limestone with 27.5% fly ash, and 65% limestone with 35% slag. The synthesized portland cements had similar early-age hydration behavior to commercial portland cement. However, waste materials significantly affected cement phase formation. The C3S--C2S ratio decreased with increasing amounts of waste materials incorporated. These differences could have implications on proportioning of raw materials for cement production when using waste materials. In the calcium sulfoaluminate-belite cement part of the research, three calcium sulfoaluminate-belite cement clinkers with a range of phase compositions were successfully synthesized from reagent-grade chemicals. The synthesized calcium sulfoaluminate

    The clinical librarian used a restricted literature searching and quality-filtering approach to provide relevant clinical evidence for the use of cancer molecular biomarkers by institutional policy makers and clinicians in the rapid review process. The librarian-provided evidence was compared with the cited references in the institutional molecular biomarker algorithm. The overall incorporation rate of the librarian-provided references into the algorithm was above 80%. This study suggests the usefulness of clinical librarian expertise for clinical practice. The searching and filtering methods for high-level evidence can be adopted by information professionals who are involved in the rapid literature review.

    This study is intended to (1) identify emerging roles for biomedical librarians and determine how common these roles are in a variety of library settings, (2) identify barriers to taking on new roles, and (3) determine how librarians are developing the capacity to take on new roles. A survey was conducted of librarians in biomedical settings. Most biomedical librarians are taking on new roles. The most common roles selected by survey respondents include analysis and enhancement of user experiences, support for social media, support for systematic reviews, clinical informationist, help for faculty or staff with authorship issues, and implementation of researcher profiling and collaboration tools. Respondents in academic settings are more likely to report new roles than hospital librarians are, but some new roles are common in both settings. Respondents use a variety of methods to free up time for new roles, but predominant methods vary between directors and librarians and between academic and hospital respondents. Lack of time is the biggest barrier that librarians face when trying to adopt new roles. New roles are associated with increased collaboration with individuals and/or groups outside the library. This survey documents the widespread incorporation of new roles in biomedical libraries in the United States, as well as the barriers to adopting these roles and the means by which librarians are making time for them. The results of the survey can be used to inform strategic planning, succession planning, library education, and career development for biomedical librarians.

    Currently, high-rise construction has received increasing attention around the world. In the big cities under construction is less space and one solution is the high-rise construction. However, high-rise buildings use special requirements, such as strength, thermal insulation, wind load and others. When concrete is exposed to continuous loads by wind or to mechanical loads, it undergoes abrasion. Resistance to this process depends on the characteristics of materials that the concrete and finishing seams are made of. Research on increasing impact and abrasion resistance of calcium sulfoferrite-based cement stone from the perspective of formation of cement stone structure will be instrumental in developing durable materials for application in high-rise construction.

  13. Concrete research using blended cements

    2001-01-01

    Concrete research increasingly involves the use of mixes containing one or more of the supplementary cementitious materials (SCMs), often in conjunction with chemical admixtures. The influence of materials is commonly evaluated on the basis of water/ cement or water/ binder ratio and SCM content as a percentage of total binder, with dosage level of chemical admixture varied to maintain workability. As a result, more than one variable is introduced at a time and the objectives of the research may not be achieved. The significance of water/ cement ratio and addition rates of admixtures are examined from a practical standpoint with suggestions for more appropriate means of evaluation of the influence of individual materials.

    2009-01-01

    The densities of principal crystalline phases occurring in Portland cement are critically assessed and tabulated, in some cases with addition of new data. A reliable and self-consistent density set for crystalline phases was obtained by calculating densities from crystallographic data and unit cell contents. Independent laboratory work was undertaken to synthesize major AFm and AFt cement phases, determine their unit cell parameters and compare the results with those recorded in the literature. Parameters were refined from powder diffraction patterns using CELREF 2 software. A density value is presented for each phase, showing literature sources, in some cases describing limitations on the data, and the weighting attached to numerical values where an averaging process was used for accepted data. A brief discussion is made of the consequences of the packing of water to density changes in AFm and AFt structures.

    the teaching role was valued.The role of teacher spilled over into the other roles of the librarian, i.e., reference service, collection development, etc. Thenext theme was the importance of collegial and administrative support, which is critical to the ability to focus on work as a teacher. The stress of multiple demands emerged as a theme, as time dedicated to teaching was often at the expense of something else. Another theme was the problems with professional education around teaching. Instruction course offerings in library schools were reported to be meagre, and some were badly planned and executed. The fifth theme involved stereotypes and misperceptions. Studies have shown that the academic library profession has been poorly understood by students and faculty. Study participants believed that many of their campus colleagues were either unaware of what they did, or were misinformed by popular culture stereotypes of librarians.Conclusions – The small sample size precluded the making of any definite conclusions based on the study results. Other limitations of the study include the relatively short amount of time spent in the interview process and the narrow range of librarians chosen to participate. The author notes that a subject pool more representative of academic librarians’ full range of opinions regarding the importance of teaching as a professional responsibility would have resulted in more complex themes emerging. While the author is aware of the study’s limitations, he feels there is value in the qualitative research design, in giving voice to individual librarians, and in the provision of insight into some of the research questions found in the literature of learning to teach and of teacher identity. Given the limitations, Walter makes three conclusions about his findings. He points out the lack of a formal introduction to teaching in many library programs which has been explored by other studies and concludes that his study “suggests that

    With an objective of saving energy and reducing greenhouse gas emission, investigations and discussions were given on a modernization project for Byuzmeyinsky Cement Factory, the only cement factory in Turkmenistan. Byuzmeyinsky Cement Factory uses the wet process which consumes a large amount of energy, is inferior in production efficiency and quality, and discharging a great amount of greenhouse effect gas. The present project will execute change of the raw material crusher into a vertical roll mill for one of the four wet kilns, and change of the facilities for raw material powder mixing and storing and clinker manufacturing into dry-type facilities using the NSP system. As a result of the discussions, the energy saving effect would be 86,321 tons of crude oil equivalent annually, and the greenhouse gas emission reducing effect would be 224,467 t-CO2 annually. The total fund amount required for the project is estimated to be 90,211,000 dollars. With regard to the profitability, the internal financial profit rate would be 9.71% after tax, and the ROE would be 18.62%, whereas the project is considered feasible. (NEDO)

    To test the solubility of dual cure resin modified resin cement in a food simulating solution and the shear bond strength compared to conventional Glass ionomer cement. The materials tested were self-adhesive dual cure resin modified cement and Glass Ionomer (GIC). Twenty Teflon moulds were divided into two groups of tens. The first group was injected and packed with the modified resin cement, the second group was packed with GIC. To test the solubility, each mould was weighed before and after being placed in an analytical reagent for 30 days. The solubility was measured as the difference between the initial and final drying mass. To measure the Shear bond strength, 20 freshly extracted wisdom teeth were equally divided into two groups and embedded in self-cure acrylic resin. Four mm sections of stainless steel bands were cemented to the exposed buccal surfaces of teeth under a constant load of 500 g. Shear bond strength was measured using a computer controlled materials testing machine and the load required to deband the samples was recorded in Newtons. GIC showed significantly higher mean weight loss and an insignificant lower Shear bond strength, compared to dual cure resin Cement. It was found that dual cure resin modified cement was less soluble than glass ionomer cement and of comparable bond strength rendering it more useful clinically for orthodontic band cementation.

    When cements appeared in the 19th century, they took the place of traditional binding materials (lime, gypsum, and hydraulic lime) which had been used until that time. Early cements can be divided into two groups, natural and artificial (Portland) cements. Natural cements were introduced first, but their widespread usage was short-lived as they were quickly replaced by artificial cements (Portland), still the most important and predominant today. The main differences between natural and artificial cements arise during the manufacturing process. The final properties of the cements are greatly influenced by differences in the raw materials and burning temperatures employed. The aim of this paper is to assess the efficiency of traditional analytical techniques (petrographic microscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR)) used to differentiate natural and artificial cements

    The original size, spatial distribution, and composition of Portland cement particles have a large influence on hydration kinetics, microstructure development, and ultimate properties of cement-based materials. In this paper, the effects of cement particle size distribution on a variety of performance properties are explored via computer simulation and a few experimental studies. Properties examined include setting time, heat release, capillary porosity percolation, diffusivity, chemical shrinkage, autogenous shrinkage, internal relative humidity evolution, and interfacial transition zone microstructure. The effects of flocculation and dispersion of the cement particles in the starting microstructures on resultant properties are also briefly evaluated. The computer simulations are conducted using two cement particle size distributions that bound those commonly in use today and three different water-to-cement ratios: 0.5, 0.3, and 0.246. For lower water-to-cement ratio systems, the use of coarser cements may offer equivalent or superior performance, as well as reducing production costs for the manufacturer.

    Full Text Available Academic libraries encounter many challenges when providing services for researchers and it is evident that use of the library in information searches has reduced significantly over time and continues to decrease.However, a study in Norway in 2007, at Vestfold University College (VUC, demonstrated that there is great potential to increase faculty staff’s use of the library’s digital resources with the right form of engagement. The findings led VUC’s library to focus on its services for this particular user group.In 2009, VUC library initiated a study to investigate the possible effects of a librarian participating as a ‘Research Group Librarian’.The research project, in which this new role was tried out, was called ‘Kindergarten space, materiality, learning and meaning-making’. This was a three year project, funded by the Research Council of Norway. There were eight part time researchers involved in this project, two senior researchers and the research group librarian.The study adopted an ethnographic approach. The research group librarian was a fully participating member of the research team throughout the project.The empirical sources for the study included:semi-structured interviews with the project leader and the participating researchers: short individual interviews at the beginning of the project with each of the research group participants; several group interviews with the majority of the research team midway in the project;observation and field notesThe results are presented under the following categories:implications for the researcher; emphasising behaviour in relation to information search and reference management skills;communication and information within, and evolving from, the project;collaboration in writing a review article;implications for the library – internal, and at VUC in general;the librarian’s role – a ‘boundary worker’?The study demonstrated that as a member of a research group a librarian can

    The aim of this book is to present the latest findings in the properties and application of Supplementary Cementing Materials and blended cements currently used in the world in concrete. Sustainability is an important issue all over the world. Carbon dioxide emission has been a serious problem in the world due to the greenhouse effect. Today many countries agreed to reduce the emission of CO2. Many phases of cement and concrete technology can affect sustainability. Cement and concrete industry is responsible for the production of 7% carbon dioxide of the total world CO2 emission. The use of supplementary cementing materials (SCM), design of concrete mixtures with optimum content of cement and enhancement of concrete durability are the main issues towards sustainability in concrete industry.

    There are two major cement solidification systems at Los Alamos National Laboratory. Both are focused primarily around treating waste from the evaporator at TA-55, the Plutonium Processing Facility. The evaporator receives the liquid waste stream from TA-55's nitric acid-based, aqueous-processing operations and concentrates the majority of the radionuclides in the evaporator bottoms solution. This is sent to the TA-55 cementation system. The evaporator distillate is sent to the TA-50 facility, where the radionuclides are precipitated and then cemented. Both systems treat TRU-level waste, and so are operated according to the criteria for WIPP-destined waste, but they differ in both cement type and mixing method. The TA-55 systems uses Envirostone, a gypsum-based cement and in-drum prop mixing; the TA-50 systems uses Portland cement and drum tumbling for mixing

    The present study aimed to characterize experimental endodontic cements using as comparative parameter MTA cement. Two experimental endodontic cements were assessed: one based on 95% tri-strontium aluminate and 5% gypsum (CE1) and another based on 50% Sr_3Al_2O_6 and 50% non-structural white cement (CE2). Experimental cements were manipulated and characterized by scanning electron microscopy (SEM), coupled to EDS mode, X-ray diffractometer (XRD) and Thermogravimetric (TG) analysis. Data analysis demonstrated that the particles of the materials used presented varied shapes and sizes, with similar elements and crystalline behavior. However, CE1 presented increased mass loss. Experimental cements presents similarities to MTA, nevertheless, further studies are encourage to determinate comparative properties with the commercially material. (author)

  11. Modelling porewater chemistry in hydrated Portland cement

    Berner, U.R.

    1987-01-01

    Extensive employment of concrete is foreseen in radioactive waste repositories. A prerequisite for modelling the interactions between concrete and formation waters is characterization of the concrete system. Available experimental data from high pressure squeezing of cement pore-water indicate that, besides the high pH due to alkali hydroxide dissolution, cement composition itself influences the solubility determining solid phases. A model which simulates the hydration of Portland cement assuming complete hydration of the main clinker minerals is presented. The model also includes parameters describing the reactions between the cement and blending agents. Comparison with measured pore-water data generally gives a consistent picture and, as expected, the model gives correct predictions for pure Portland cements. For blended cements, the required additional parameters can, to some extent, be derived from pore-water analysis. 14 references, 1 figure, 4 tables

    In recent times the nuclear industry has thrown up challenges which cannot be met by the application of conventional civil and materials engineering knowledge. The contributions in this volume investigate all aspects of cement performance. The scope of the papers demonstrates the current balance of activities which have as their objective the elucidation of kinetics and immobilization, determining material interactions and of assessing future performance. The papers reflect the varied goals of the sponsors who include national governments, the Commission of the European Communities and the nuclear industries. In six parts attention is paid to the durability of cement and concrete in repository environment; interactions between cement, waste components and ground water; properties and performance of cement materials; leach behavior and mechanisms, diffusional properties of cement and concrete, including porosity-permeability relationships; and thermodynamics of cementitious systems and modelling of cement performance

    Cement-in-cement revision hip arthroplasty is an increasingly popular technique to replace a loose femoral stem which retains much of the original cement mantle. However, some concern exists regarding the retention of the existing fatigued and aged cement in such cement-in-cement revisions. This study investigates whether leaving an existing fatigued and aged cement mantle degrades the mechanical performance of a cement-in-cement revision construct. Primary cement mantles were formed by cementing a polished stem into sections of tubular steel. If in the test group, the mantle underwent conditioning in saline to simulate ageing and was subject to a fatigue of 1 million cycles. If in the control group no such conditioning or fatigue was carried out. The cement-in-cement procedure was then undertaken. Both groups underwent a fatigue of 1 million cycles subsequent to the revision procedure. Application of a Mann-Whitney test on the recorded subsidence (means: 0.51, 0.46, n=10+10, P=0.496) and inducible displacement (means: 0.38, 0.36, P=0.96) revealed that there was no statistical difference between the groups. This study represents further biomechanical investigation of the mechanical behaviour of cement-in-cement revision constructs. Results suggest that pre-revision fatigue and ageing of the cement may not be deleterious to the mechanical performance of the revision construct. Thus, this study provides biomechanical evidence to back-up recent successes with this useful revision technique. Copyright © 2012 Elsevier Ltd. All rights reserved.

    In a fusion reactor or tritium handling facilities, contamination of concrete by tritium and subsequent release from it to the reactor or experimental rooms is a matter of problem for safety control of tritium and management of operational environment. In order to evaluate these tritium behavior, interaction of tritiated water with concrete or cement should be clarified. In the present study, HTO sorption and subsequent release from cement were studied by combining various experimental methods. From the basic studies on tritium-cement interactions, it has become possible to evaluate tritium uptake by cement or concrete and subsequent tritium release behavior as well as tritium removing methods from them

    Rubber crumb obtained from worn out tires has been increasingly used over the last 15-20 years, especially in manufacture of asphalt and cement concrete mixtures. This review pays principal attention to application of the rubber crumb to cement concrete mixtures. Use of the rubber crumb in cement concrete is not as successful as in asphalt concrete mixtures, due to incompatibility problems linked to chemical composition and a significant difference in rigidity between the rubber crumb and concrete mixture aggregates. Different methods are proposed and studied to mitigate the adverse influence and increase the beneficial effects of the rubber crumb when added to cement concrete.

    In this study, we identify different controls on cementation in a chalk reservoir. Biot’s coefficient, a measure of cementation, stiffness and strength in porous rocks, is calculated from logging data (bulk density and sonic Pwave velocity). We show that Biot’s coefficient is correlated...... that some degree of pore filling cementation occurred in Kraka (Alam, 2010). Lack of correlation between Biot’s coefficient and Gamma Ray (GR) indicates that the small amount of clay present is generally located in the pore space, thus not contributing to frame stiffness. While there was no compositional...... control on cementation via clay, we could infer that stratigraphy impacts on the diagenetic process....

    In recent years, tremendous progress has been made toward providing health information in Africa, in part because of technological advancements. Nevertheless, ensuring that information is accessible, comprehensible, and usable remains problematic, and there remain needs in many settings to address issues such as computer skills, literacy, and the infrastructure to access information. To determine how librarians might play a more strategic role in meeting information needs of health professionals in Africa, the author reviewed key components of information systems pertinent to knowledge management for the health sector, including access to global online resources, capacity to use computer technology for information retrieval, information literacy, and the potential for professional networks to play a role in improving access to and use of information. The author concluded that, in regions that lack adequate information systems, librarians could apply their knowledge and skills to facilitate access and use by information seekers. Ensuring access to and use of health information can also be achieved by engaging organizations and associations working to enhance access to health information, such as the Association for Health Information and Libraries in Africa. These groups can provide assistance through training, dissemination, information repackaging, and other approaches known to improve information literacy.

    Objective A critical element in conducting a systematic review is the identification of studies. To date, very little empirical evidence has been reported on whether the presence of a librarian or information professional can contribute to the quality of the final product. The goal of this study was to compare the reporting rigor of the literature searching component of systematic reviews with and without the help of a librarian. Method Systematic reviews published from 2002 to 2011 in the twenty highest impact factor pediatrics journals were collected from MEDLINE. Corresponding authors were contacted via an email survey to determine if a librarian was involved, the role that the librarian played, and functions that the librarian performed. The reviews were scored independently by two reviewers using a fifteen-item checklist. Results There were 186 reviews that met the inclusion criteria, and 44% of the authors indicated the involvement of a librarian in conducting the systematic review. With the presence of a librarian as coauthor or team member, the mean checklist score was 8.40, compared to 6.61 (plibrarian. Conclusions Findings indicate that having a librarian as a coauthor or team member correlates with a higher score in the literature searching component of systematic reviews. PMID:27822147

    The Medical Education Task Force of the Task Force on Vital Pathways for Hospital Librarians reviewed current and future roles of health sciences librarians in medical education at the graduate and undergraduate levels and worked with national organizations to integrate library services, education, and staff into the requirements for training medical students and residents. Standards for medical education accreditation programs were studied, and a literature search was conducted on the topic of the role of the health sciences librarian in medical education. Expectations for library and information services in current standards were documented, and a draft standard prepared. A comprehensive bibliography on the role of the health sciences librarian in medical education was completed, and an analysis of the services provided by health sciences librarians was created. An essential role and responsibility of the health sciences librarian will be to provide the health care professional with the skills needed to access, manage, and use library and information resources effectively. Validation and recognition of the health sciences librarian's contributions to medical education by accrediting agencies will be critical. The opportunity lies in health sciences librarians embracing the diverse roles that can be served in this vital activity, regardless of accrediting agency mandates.

    2014-06-01

    The objective of this study was to explore the role librarians play on research teams. The experiences of a librarian and a faculty member are situated within the wider literature addressing collaborations between health science librarians and research faculty. A case study approach is used to outline the involvement of a librarian on a team created to investigate the best practices for integrating nurses into the workplace during their first year of practice. Librarians contribute to research teams including expertise in the entire process of knowledge development and dissemination including the ability to navigate issues related to copyright and open access policies of funding agencies. The librarian reviews the various tasks performed as part of the research team ranging from the grant application, to working on the initial literature review as well as the subsequent manuscripts that emerged from the primary research. The motivations for joining the research team, including authorship and relationship building, are also discussed. Recommendations are also made in terms of how librarians could increase their participation on research teams. The study shows that librarians can play a key role on interprofessional primary research teams. © 2014 The authors. Health Information and Libraries Journal © 2014 Health Libraries Group.
