Résumé :
This study aims to examine the views on digitization of eight respondents, all working at different libraryinstitutions in Sweden, and how their views are reflected in their library's digitization strategies. The poll wasconducted on the basis of Ingrid Mason's theory of information standards, their structure and sociopoliticalnature. The informantion standards are divided into three aspects, curatorial, semantic and technical, and theyaffect selection of, intellectual and physical access to the digitized material, which in the end is what constitutes the digital cultural heritage.The background to the study is that the Swedish library institutions in the current situation lacks a nationalstandard or a common strategy for the digitization of cultural heritage, while it is still implemented digitizationprojects at many library institutions. The method used is qualitative, structured interviews with open-ended questions.The study shows that one of the main motives behind the libraries' digitization projects is to make librarymaterials available in a new way, creating greater opportunities for the users to take advantage of the material.The library users are the ones who mainly control what is digitized, although aspects of preservation ismentioned. Furthermore, it appears that the respondents believe that digitization offers improved capabilities tosearch and learn more about the collections, but the actual work of image capture, the addition of metadata,presentation to users and long-term preservation is very complex.Views on what it is to be digitized, how the material should be selected and provided with metadata and howit should be presented to users is what creates the standards that libraries use when they digitize their materials,and digitization of library materials creates new conditions for new users to access and use library material.This is a two years master’s thesis in Archive, Library and Museum studies.

Résumé :
For rare book collections, a considerable challenge is involved in evaluating collection materials in terms of their inherent value, which includes the textual and intangible information the materials provide for the collection's users. Preservation management in rare book collections is a complex and costly process. As digitization and other technological advances in surrogate technology have provided new forms representation, new dilemmas in weighing the rare book's inherently valuable characteristics against the possibly lesser financial costs of surrogates have arisen. No model has been in wide use to guide preservation management decisions. An initial iteration of such a model is developed, based on a Delphi-like iterative questioning of a group of experts in the field of rare books. The results are used to synthesize a preservation management framework for rare book collections, and a small-scale test of the framework has been completed through two independent analyses of five rare books in a functioning collection. Utilizing a standardized template for making preservation decisions offers a variety of benefits. Preservation decisions may include prioritizing action upon the authentic objects, or developing and maintaining surrogates in lieu of retaining costly original collection materials. The framework constructed in this study provides a method for reducing the subjectivity of preservation decision-making and facilitating the development of a standard of practice for preservation management within rare book collections.

Bibliography: leaves 99-112.
Many experts in the global library and archive sector consider preservation a fundamental responsibility for all institutions and professionals. However, preservation is not yet an established core topic in the professional education of South African information workers, despite the increased availability of education and training options in recent years. Many of the current course and module offerings at university and technikon teaching departments do not cover the essential preservation issues adequately. As a result, professional librarians and archivists often feel ill prepared to address preservation issues in the working world. There are other options for learning about preservation outside the traditional classroom environment including publications and short workshops often organised by interested professional organisations.

A material can enhance or distract from the end-user experience and is an important decision for designers. As such, material libraries exist to provide designers with a hands-on resource to understanding materials beyond just data sheets. When we took 2.009, a mechanical engineering capstone class, we found it difficult to decide which materials to use. Thus, in this work, we sought to create a materials library under an engineering context for student product designers to use. To understand how material libraries function and which materials would best suit the collection, we benchmarked three physical and one virtual material library. We also sought input from those involved in product design classes, such as past students, Professor Wallace who teaches 2.009, and Pappalardo shop staff who support the students in their creations. We also looked at past receipts to supplement our knowledge as well as looked at distributors and what they offered to expand our selection. Our six main categories of materials were: woods, metals, composites, polymers, fabrics, and Smooth-On products. The material libraries key criteria were to be well organized, portable, and useful. We went through several design sketches before deciding on utilizing a modular wire rack so we could place dividers and shelves as necessary. A coding system was also implemented that included main categories and subcategories with associated colors to help with the user experience of quickly locating, using, and returning. Each material comes attached with information and a more complete overview is located in an information packet. While this first version the materials library was met with excitement, it is by no means complete. As such, there are also a number of ways to improve the experience and the collection.

Glynn, Deborah. « The preservation and conservation of ink jet and electrophotographic printed materials ». Thesis, Open University, 2001. http://oro.open.ac.uk/58177/.

Texte intégral
Résumé :
This research project has investigated the light fastness of ink jet and electrophotographic printed materials by the means of an extensive accelerated and natural ageing test programme. The effect of visible radiation of different wavebands on the deterioration of a selection of ink jet printed materials has also been assessed. The findings of the research indicate that all of the ink jet printed materials tested are sensitive to light and should not therefore, be put on permanent display. Most of the ink jet printed samples exhibited greater light sensitivity to the shorter wavelengths of the visible spectrum, than the longer wavelengths, with damage decreasing as wavelength increases. This relationship was not evident with the cyan and blue printed samples, which showed that their light sensitivity was determined by the spectral absorption characteristics of the printed patch. Some of the ink jet printed materials produced erratic fading rates on exposure to light. This phenomenon was attributed to either the occurrence of photochromism or the disintegration of the dye particles in the ink, but further testing needs to be conducted to gain a better understanding of this reaction. Other factors also influenced the light fastness of the ink jet materials, such as the type of paper employed for printing, ink concentration and ink combination. The electrophotographic printed materials were found to be more stable to light, although the yellow toner from some of the systems would show noticeable fading after approximately 65 to 325 years on permanent display (at 50 lux for eight hours per day). A range of basic conservation treatments was also been investigated and the results indicated that ink jet print materials are very sensitive to all forms of aqueous treatments. Finally, thermal/dark ageing has been performed on the digital printed papers employed in this investigation. The conclusion is that all of the papers are prone to yellowing in storage.

Résumé :
This mini-dissertation reports on the guidelines for digitisation that were developed for the University of Zimbabwe Library. A literature study and an empirical investigation were done in order to come up with the guidelines. The literature study was primarily used to inform the researcher on those aspects of digitisation for which guidelines could be developed. A qualitative research design was adopted in this study. Semi-structured interviews were used to collect data from five South African institutions that are involved in digitisation. Digitisation managers from the five institutions were interviewed in this study. The data from the interviews and the literature study were used to come up with the proposed guidelines for digitisation at the University of Zimbabwe Library. The guidelines that were developed as a result of this study specifically address digitisation standards and best practices, technologies for digitisation, costs and sustainability of digitisation, intellectual property issues, steps in digitisation, challenges in digitisation and the selection of materials for digitisation. Although some of the respondents expressed that digitisation can be used as a sustainable method of preservation, this research could not demonstrate that current practices would be reliable in the long term.

This work looks at a range of copying processes used between 1950 and 1970 and which can be gathered under the heading 'Thermography'. Thermography is a broad term covering those processes which utilise heat to produce their image. The main aims of the work were: to examine how and when each process was used; to determine the chemistry of each process; to examine the permanence of existing copies produced using the various processes; and to look at possible ways of improving the preservation prospects of these copies. These aims were addressed through both primary and secondary research mechanisms. Research included examination of documentary source material, seeking out persons with first hand knowledge of the development of the processes, as well as analysis of extant copies from the various processes. Finally a series of preliminary experiments into the aging properties of the papers and the possibilities of preservation through the use of protective materials were carried out.

Résumé :
The basic aim of this mini-dissertation was to explore the prospects of digitisation at the University of Ghana Library System (UGLS). The research followed a qualitative approach and a case study research design was adopted. A thorough literature study was conducted. The primary purpose of the literature was to inform the research on the questions and objectives raised on the aspects of digitisation to understand the dynamics and complexity of digitisation. Six staff from the UGLS digitisation programme were purposively sampled for in-depth interviews for their direct involvement in the UGLS digitisation programme. Semi-structured interviews were then conducted with UGLS digitisation managers and the current IT and digitisation operations staff to collect data. During the interviews, the following issues associated with digitisation were addressed: policy, planning, goals and priorities, selection criteria, skills and expertise, digital preservation and long-term access, issues and challenges; solutions and recommendations to digitisation constraints of the UGLS. These issues were used to identify and develop themes where thematic analyses of research data were done. Specific recommendations were also develop to share with UGLS to address the digitisation policy and planning issues, selection issues, human resource and skills requirements; the critical challenges, resource requirements, long-term preservation and access of digitised content and the sustainability of digitisation programme. Final recommendations were made based on the findings and conclusions of the research to advise on the sustainability of the UGLS digitisation programme.

ENGLISH ABSTRACT: Kepi is a refreshing, fermented dairy beverage that has been consumed for centuries and is traditionally made by incubating Kepi grains in milk. The Kepi grain is a complex starter culture consisting of a variety of lactic acid bacteria and yeasts. The successful marketing of the grains requires the effective preservation of the microbes present in the grains as well as an appropriate packaging that will retain the acidification activity of the preserved grains over an extended period of time. The aim of this study was to evaluate different preservation techniques and packaging materials in terms of their respective abilities to retain grain viability and activity over an extended storage period. Four different preservation techniques (freezing at -18°C, refrigeration at 4°C, air-drying and Iyophilisation) and three packaging materials including a low density polyethylene film (LOPE), an oriented polyester film (OPET) and a metallised oriented polyester film (MOPET), were evaluated. Activity tests were used to evaluate the impact of the preservation techniques in terms of the retainment of the acidification activity of the preserved grains, and the storage potential of the preserved and packaged grains. The activity tests included changes in pH, %TA, lactic acid production and lactose and volatile compound content over an 18 h fermentation period. In addition, the microbial viability of the packaged Iyophilised grains after two months of storage, was also investigated. Frozen and refrigerated grains showed the best retainment of the acidification activity over a 10-month storage period. Air-drying and Iyophilisation showed a good retention of the activity up to three months of storage, but the application of these techniques both resulted in a retarded initial acidification activity. After 10 months of storage, the air-dried and Iyophilised grains showed only a low acidification activity. No volatile compounds could be detected during the course of the fermentation period, due to the relative short fermentation period of 18 h. Overall, the best retainment of the fermentation activity was given by the LOPE and the OPET packaging films. However, the storage period had a considerable influence on the retention of the activity of the packaged Iyophilised grains. The viability study of the Iyophilised packaged Kepi grains after two months of storage showed leuconostocs and lactobacilli to be the prevalent microbes in the grains. Low microbial counts were obtained from the lactococciselecting medium for all three of the differently packaged Kepi grains, whereas no growth was observed on the media that selected for the propionibacteria and yeasts. The OPET packaging film provided the best preservation of the microbial composition. It was, therefore, concluded that all four preservation techniques would be suitable for the preservation of Kepi grains and the subsequent storage at room temperature for three months. However, for storage periods of 10 months or longer the use of freezing and refrigeration are recommended as most suitable preservation techniques. All three of the packaging materials proved to be suitable for the packaging and storage of the Iyophilised Kepi grains for periods of up to one month. However, for storage periods of two months or longer, the use of the OPET film for the packaging and retainment of the acidification activity of the Iyophilised grains, can be recommended.
AFRIKAANSE OPSOMMING: Kepi is 'n eeu-oue verfrissende, gefermenteerde suiweldrankie wat tradisioneel vervaardig word deur Kepikorrels in melk te inkubeer. Hierdie Kepikorrels bestaan uit 'n komplekse samestelling van hoofsaaklik melksuurbakteriee en giste. Die effektiewe preservering en verpakking van die korrels is belangrike voorvereistes vir die suksesvolle bemarking daarvan. Dis belangrik dat die preserverinq en die verpakking van die korrels 'n positiewe bydrae sal lewer tot die behoud van die fermentasie-aktiwiteit van die mikrobes in die korrels oar 'n verlengde opbergingsperiode. Die doel van hierdie studie was om die opbergingspotensiaal van verskillend gepreserveerde en -verpakte Kepikorrels te evalueer in terme van die behoud van die lewensvatbaarheid en fermentasie-aktiwiteit van die samestellende mikrobes. Vier verskillende preserveringstegnieke (bevriesing by -18°C, verkoeling by 4°C, lugdroging en vriesdroging) en drie verskillende tipes verpakkingsmateriale, nl. 'n "low density polyethylene film" (LOPE), 'n "oriented polyester film" (OPET) en 'n "metallised oriented polyester film" (MOPET) was qeevalueer. Aktiwiteitstoetsing was gebruik om die impak van die verskillende preserveringstegnieke en die verpakkingsmateriale op die behoud van die fermentasie-aktiwiteit van die Kepikorrels te ondersoek. Die verskillende aktiwitieitstoetse wat gedoen is, het die meting van die verandering in pH, %TA, melksuur- en laktosekonsentrasie oor 'n fermentasieperiode van 18 h ingesluit. Tesame met die aktiwitietstoetsing IS die lewensvatbaarheid van die gevriesdroogde, verpakte Kepikorrels na twee maande van opberging ook ondersoek. Die bevrore en verkoelde Kepikorrels het die beste behoud van aktiwitiet na 'n 10-maande opbergingsperiode getoon. Die gelugdroogde en gevriesdroogde korrels het 'n goeie behoud van aktiwiteit getoon vir 'n opbergingstydperk van tot drie maande, maar beide die lugdroging- en vriesdrogingstegnieke het 'n aanvanklik vertraagde fermentasie-aktiwitieit getoon. Na 'n : opbergingsperiode van 10 maande het beide die gelugdroogde en gevriesdroogde korrels egter 'n lae fermentasie-aktiwiteit getoon. As gevolg van 'n relatiewe kort fermentasieperiode van 18 h kon geen vlugtige komponente in die Kepimonsters gevind word nie. Die LDPE- en OPET-verpakkingsmateriale het die beste behoud van die fermentasie-aktiwiteit van die gevriesdroogde korrels getoon. Die opbergingsperiode het egter 'n aansienlike impak op die aktiwitietsbehoud van die korrels gehad. Die lewensvatbaarheidstudie het aangetoon dat Leuconostoc- en Lactobacillus-spesies die oorheersende mikrobes in die verpakte, gevriesdroogde Kepikorrels na 'n opbergingsperiode van twee maande was. Lae mikrobiese tellings vir al drie van die verpakkingsmateriale was gevind op die Lactococcusselekterende medium, en geen mikrobegroei kon op die giste- en propionibakteriee-selekteringsmedium waargeneem word nie. Die beste behoud van die mikrobiese samestelling in die verpakte, gevriesdroogde Kepikorrels was gevind vir die OPET-verpakkingsmateriaal. Die gevolgtrekking kan gemaak word dat al vier die preserveringstegnieke geskik is vir die preservering van die Kepikorrels en die daaropvolgende opberging van drie maande by kamertemperatuur. Vir opbergingsperiodes van 10 maande en langer word die gebruik van bevriesing en verkoeling aanbeveel as die mees geskikte preserveringstegnieke. AI drie verpakkingsmateriale kan gebruik word vir die verpakking en opberging van gevriesdroogde Kepikorrels vir 'n tydperk van een maand. Indien 'n opbergingsperiode van twee maande of langer verlang word, word die OPET-verpakkingsmateriaal aanbeveel vir die suksesvolle behoud van die fermentasie-aktiwiteit van die Kepikorrels.

Texte intégral
Résumé :
This project presents the first large-scale study of the preservation and alteration of Late Bronze Age vitreous materials from the Near East. An understanding of the processes that affect buried glasses is of importance both in the conservation of ancient artefacts and as analogues for the disposal of vitrified nuclear waste. This project has focused on the vitreous material from Nuzi, a mid 2nd millennium BC site in Iraq, held at the Semitic Museum at Harvard University. This is one of the largest assemblages of vitreous material known from the Late Bronze Age, containing a wide range of objects. A survey was made of the assemblage and the distribution of vitreous materials across the site was established. It was found that the majority of these materials are associated with high-status and religious areas of the city. Over 150 samples of vitreous material, including 90 LBA glasses, were characterised in detail, using a variety of analytical techniques including, SEM-EDS, SEM-WDS, LA-ICPMS and XRD. Compositional analysis suggested that the antimony-opacified glasses may have been manufactured at a higher temperature than the translucent glasses; supported by a series of experiments replicating the opaque glasses. The results also showed that the alteration of the glasses was highly variable, both in the degree of alteration and the composition and morphology of the alteration layers. This variability could not be correlated with the original location of the objects on the site, including objects from the same room, and it was concluded that small microenvironmental changes were responsible for producing the large range of variation seen. In addition, a distinction was noted between the alteration of translucent and opaque glasses, which was found to be repeated in the dissolution experiments with the opaque glass having a much higher dissolution rate. The alteration experiments have established a dissolution rate for LBA composition glasses and indicated that replica glasses are a good analogue for archaeological glasses of the same type. It is suggested that the dependence on the burial environment of archaeological glasses, an open system, compared to the closed system of nuclear waste glasses means that the use of data from archaeological glasses in looking at the effects of long-term burial on nuclear waste glasses has to be carefully applied.

An experimental study was performed to determine the effects on Corona Phase Molecular Recognition (CoMoRe) of bioconjugating a host of small molecules to DNA wrapped single-walled carbon nanotubes. In addition, the study observed the effects of the DNA sequence length on the subsequent effectiveness of the small molecules to alter the corona phase. The conjugation of small molecules was shown to alter both the intensity and the position of the fluorescence and absorbance profile. The length of the DNA sequence was found to change the small molecule's ability to alter the fluorecence spectra of the wrapped nanotubes. The EDC/sulfo-NHS reaction was done to conjugate the small molecules to two identical DNA sequences with varying lengthes. Through the methods of ultraviolet-visibile-near infrared absorption spectroscopy, near infrared fluorescence spectroscopy, and high-performance liquid chromatography characterization and structural analysis were performed. The results showed the successful conjugation of the small molecules to the amino-modified DNA and an alteration in the corona phase. The small molecules were found to bind to the DNA at multiple locations and the length of the sequence was found to have an effect on the corona phase.

Résumé :

Främsta anledningen till en tilläggsisolering är att det önskas bättre energihushållning i en byggnad. Detta kan göras med olika material och olika tekniker. Inom byggnadsvårdssammanhang förs det en diskussion om de fuktbuffrande materialen är bättre vid tilläggsisolering då de är hygroskopiska än de icke hygroskopiska som är mest frekvent använda i det konventionella byggandet. Denna rapport utvärderar om det finns några dokumenterade fakta som styrker att de hygroskopiska och ekologiska materialen fungerar bättre i byggnadsvårdssammanhang än de icke hygroskopiska. Olika isolermaterial från de två nämnda grupperna jämförs utifrån olika parametrar.


This report evaluates if there are any known facts that support that the hygroscopic and ecologic materials are better in supplement insulation than non hygroscopic. Different kind of insulate materials from these two mentioned groups are compared from without different kind of parameters.

Résumé :

Our collective memory, the history that is cultivated through reflection, documentation, and consensus of historical data, is predicated upon the citizenry having access to the historical materials that society has created. Digitization has enabled greater public access to those materials. However, are items being scanned or digitally photographed to create surrogates that are then not made available to the world? The impetus for this study is to delve into whether or not intentional or unintentional personal choices play a role in determining which items archivists transform into digital surrogates; both in the decision of what to digitize and what to make available to the public on the World Wide Web. When one archival collection is prioritized over another or when it is not possible to digitize an entire collection, what rationale is used to determine which items will be digitized and published online? Do intentional or unintentional personal choices come into play in the decision-making? To answer these questions, four case studies were conducted, involving the random sampling of online collections and concomitant interviews of archivists. The purpose of this study is to enhance archivists’ understanding of the reasons that guide the digitization decision-making process. Through such understanding, archivists can be more proactive in the decision-making process to realize the benefit of digitizing and publishing archival materials that ultimately affect collective memory. The findings of this research revealed that in the case of the four institutions assessed, archivists do use personal choice to determine which materials within an archive are digitized.

Résumé :
Institutions that recognize the value of digital geographic legacy data for future use develop the motivation to preserve the data for the long term. International standards on preservation, such as for an open archival information system (OAIS), require having one or more designated communities identified for whom to preserve the data to adjust preservation measures to the communities’ needs. Lacking scientific literature about designated communities and the way to identify them, we use qualitative research methods to build basic knowledge on western culture user communities of legacy geodata (goal one) and to use this knowledge to adapt existing preservation practice, specifically appraisal, of the Institute for Cartography and Geology in Catalonia (goal two). The Delphi method and focus group interviews are used to reach these goals. As results, we get characteristics of thirteen user types of different professional profiles. We show that they can be clustered into six groups, of which four are relevant to a long-term archive: geographers, historians, urban planners and the general public. Through interviewing members of these four clusters, we extracted characteristics that are mentioned by various preservation guidelines as relevant for appraisal and selection of geodata: the interaction type with the data (interaction type), the data age range users are interested in (time range), their technological knowledge and in particular knowledge of geographic information systems (GIS knowledge), the maximal time span between data acquisition they could work with (acquisition interval), the preferred type of product, scales and file formats and the significance of the user group. The resulting picture of the Catalonian users was employed to recommend a relevant designated community to the ICGC and to illustrate how that might influence detailed appraisal decisions for part of their production. Users input also allowed us to evaluate the importance of existing appraisal criteria for geodata. Thanks to triangulation of the Delphi study results with the user input we can conclude that the Delphi method is an efficient way to predict legacy geodata user profile characteristics. Nevertheless, direct user interaction reveals far more details that can influence preservation decisions. Practical application of the profiles showed that some modules were not useful for appraisal; e.g., file formats. By applying what we have learned about user needs to appraisal criteria and other preservation decisions we give the user a voice that will compete in the final decisions about implementations of user-adapted legacy geodata preservation with technical, organizational and legal aspects.
La motivación de las instituciones que reconocen el valor de datos geográficos heredados para su uso futuro es poder preservarlos a largo plazo. Estándares internacionales de preservación como el ‘Open archival information system (OAIS)’ requieren que se identifiquen grupos de usuarios potenciales (comunidades designadas) a cuyas necesidades se ajusten las medidas de preservación. Las metas de este trabajo son la creación de conocimientos básicos sobre comunidades de usuarios de datos geográficos heredados (primera meta). El uso de este conocimiento para adaptar prácticas de preservación existentes del Institut Cartogràfic i Geològic de Catalunya (ICGC), en particular la valoración de archivos, es la segunda meta. El método Delphi se usó para alcanzar la primera meta y a través de entrevistas en grupos focales conocimos usuarios de datos geográficos heredados en Cataluña, lo que permitió sacar conclusiones para la segunda meta. Como resultado, obtenemos las características de trece tipos de usuarios con distintos perfiles profesionales. Demostramos que se pueden agrupar en seis grupos gracias a la similitud de sus necesidades. Cuatro de estos grupos son relevantes para un archivo a largo plazo: geógrafos, historiadores, planificadores urbanos y el público en general. Entrevistando miembros de estos cuatro grupos obtuvimos características que son mencionadas por varias directrices de preservación digital como relevantes para la valoración y la selección de datos geográficos. Estas características son: el tipo de interacción con los datos, el rango temporal que interesa a los usuarios, su nivel de conocimiento de tecnologías, el intervalo de tiempo máximo entre dos adquisiciones de datos por parte del archivo con el que puede trabajar el usuario, el tipo de producto, la escala y los formatos de fichero preferidos y, finalmente, la importancia del grupo. Los perfiles resultantes de los usuarios catalanes se usaron para recomendar una comunidad designada al ICGC y para mostrar, en parte de su producción, cómo la comunidad puede influir en decisiones de valoración concretas. Concluimos que el método Delphi es eficiente para predecir características de perfiles de usuarios de datos geográficos heredados. Sin embargo, la interacción directa con el usuario reveló más detalles que pueden influir decisiones relacionadas a la preservación digital. La aplicación práctica de los perfiles mostró que no todas las características fueron útiles para la valoración de archivos. Las opiniones de usuarios recogidos durante este proceso competirán en la decisión final sobre la implementación de medidas de preservación con argumentos técnicos, organizativos y legales.

The Broad Institute is a world leader in genomic sequencing. The Institute gained prominence during the Human Genome Project and has continued to be the nation's leading public laboratory for genomic sequencing projects. The Broad Institute has done this by taking advantage of economies of scale, rapid process innovation, and new process implementation. Strong execution has made The Broad Institute the lowest cost and highest quality sequencing operation in the country. As biological science evolves, The Broad Institute will focus on low-volume, highly targeted areas of a genome rather than high-volume, full genome sequencing projects. In order for the Institute to maintain high-quality output at low cost, it must change its operations strategy from mass production to flexible, lean production. The operations organization has begun the lean production journey by hiring operations focused managers and initiating a Six Sigma program to utilize their employees to innovate and optimize processes. This effort has been supplemented with 5S (systematic organization) and information systems that improve communication between groups.
(cont.) This thesis will focus on engineering and management issues relating to The Broad Institute and its quest to maintain quality and cost leadership among genomic sequencing laboratories. Specifically, the thesis will focus on the following items; * Preventing organism sample swaps by implementing operations changes that minimize operator error and provide electronic sample tracking through the use of Datamatrix (two dimensional) barcode technology. * Minimizing inherent process variability by increasing reagent inventory turnover and eliminating the use of expired chemicals. * Increasing the flexibility of the production process to easily handle high-mix, low-volume projects, such as the Cancer Human Genome Project.

Academic libraries in South Africa are facing the challenge of tighter budgets, increasing student enrolments, greater diversity in students' backgrounds and library experience, and a call for greater accountability to all the stakeholders. The effectiveness of a library service can be measured in terms of the availability and accessibility of library materials, two attributes of a library's document delivery capability. This study focused on the availability of prescribed materials for undergraduate students in an academic library. It involved a micro-evaluation of the immediate materials availability rate in a short loan collection, by using a combination of a quantitative simulation study, and a qualitative user survey. Generally, the availability rates determined were high, which suggests a high degree of collection adequacy. However, the user study confirmed that many SLC users experienced difficulties in using the system, indicating a need for continuous user education programmes and constant dialogue between the staff and the users concerning future service improvements. The study indicated that overall materials availability rates can be misleading if accepted at face value. A introspective analysis of the reasons for the non-availability of high-demand materials revealed hidden access barriers such as poor information retrieval skills on the part of the users and certain inefficient organisational procedures on the part of the library. The study reiterates the fundamental importance of constructive communication between the various stakeholders in meeting the educational goals of the institution and the necessity of regular library performance evaluation to ensure a dynamic, proactive service. The coexistence of print-based and electronic resources in the forseeable future underscores the importance of convenience and accessibility factors in making required documents available to the users.

Résumé :
This study measured and explored changes in perceptions of the roles and responsibilities of the library media specialist when the level of collaboration increased. Seven library media specialists targeted four members of their educational communities with whom to increase collaborative activities. Before and after the collaboration began, the library media specialists, the teachers with whom they chose to collaborate, other members from the same educational community, and a control group that did not participate in increased collaboration were given a roles and responsibilities rank-order form. This form was used to measure changes in perceptions regarding the importance of the three roles and selected responsibilities related to the three roles before and after the collaborative experience. The library media specialists and the targeted teachers also kept reflection logs to record factors that enhanced collaboration, factors that inhibited collaboration, and any changes in their teaching style as a result of the collaborative experience. Results indicate that the participating library media specialists themselves experienced the most change. Role identification remains a problem as library media specialists seek to become teaching partners with classroom teachers yet still must keep the library media center aligned with school and district goals and move toward making it an information center that provides information resources for all members of the educational community in an effective, efficient and timely manner. Major enhancers to increased collaboration included flexible scheduling of the library, sharing ideas and resources, partnership in teaching, and student achievement. Major inhibitors included time, wanting to keep things the way they were, and lack of resources. Changes in teaching practice included working with another professional instead of in isolation, integrating many resources into the lesson to provide for the learning needs of all students, the incorporation of technology into the lesson, and an awareness of the roles of both library media specialists and teachers.

Includes bibliographical references (leaves 130-143).
The paper deals with the role of literacy materials in adult education in two Cape Town public libraries, namely Bellville South and Milnerton public libraries. Adult education is education that is provided to adult who lack basic education. It involves the teaching of writing, reading, calculation skills and developmental and functional skills such as income generation skills. Literacy programmes are supported by both teaching and reading materials that are usually made available in public libraries and literacy classes. The objectives of the study were to investigate the availability of locally produced literacy materials for use in literacy programmes in public libraries, the types and features of these materials and the suitability of literacy materials in acquisition of literacy skills. Milnerton and Bellville South public libraries were used as case studies because they had literacy programmes and literacy materials in their libraries. The Stikland Learning Centre was also included because it was partly managed by the Bellville South librarian. The enrolled learners in these literacy programmes, facilitators, librarians and providers were interviewed using face to face interviews. Publishers, (Viva Books. New Readers Project and Project literacy) were also interviewed. The study showed that both public libraries provided literacy programmes that aim to equip the learners with survival and functional skills. Although they also provided literacy materials to support and maintain the literacy skills, such materials were not sufficient in literacy classes because some learners did not have literacy materials in their classes. The available reading materials in public libraries also need to be adapted so that they can meet the educational and cultural needs of the users. The research also showed that there are two types of literacy materials, namely learning or instructional and reading or informational materials. Learning materials include study guides, manuals and worksheets. They are usually provided by the literacy providers and their main aims are to support the acquisition of literacy skills and they are also used for assessment purposes. Reading or informational materials are usually provided by the public libraries and they are used to maintain the newly acquired skills. The availability of these materials is important for the success of literacy programmes and to avoid relapse into illiteracy. These materials are published by various publishers such as New Readers Project (NRP), Viva Books. Project Literacy (literacy provider) and government departments such as the Department of Education. They are published in various South African languages. Both learning and reading materials were characterized with simple languages, colourful pictures and large fonts, aiming to equip learners with the developmental and survival skills that are based on their daily activities. The learners' daily activities included reading the bus/train schedule, writing CVs and job searching related skills, reading medical prescription and reading road signs. The use of either local languages or official language in these materials is determined by the needs of the learners and the language that is used in their literacy programmes.

Résumé :
Lors de leur stockage ou de leur exposition, les objets du patrimoine sont soumis à des processus physico-chimiques d’altération liés à leur environnement et en particulier à l’action de polluants primaires (e.g. dioxyde de soufre, oxydes d’azote), secondaires (ozone) ou de composés organiques volatils (COVs). Il a été démontré que ces gaz/vapeurs se comportent comme des agents d’hydrolyse et d’oxydation. L’acide acétique fait partie des COVs ayant un impact considérable et reconnu dans la conservation des objets du patrimoine en particulier des films photographiques. En vue de lutter contre ses effets délétères, ce projet de thèse s’est focalisé sur la conception de nouveaux matériaux poreux hybrides multifonctionnels appelés « Metal-Organic Frameworks » (MOFs) pour la capture sélective de l’acide acétique en présence d’humidité (40% humidité relative) et à température ambiante. Les remarquables propriétés d’adsorption (sensibilité, sélectivité et capacité) et la grande versatilité des MOFs (balance hydrophile/hydrophobe, taille/forme des pores,…) ont été utilisés pour préconcentrer de façon sélective l’acide acétique en milieu humide. Les matériaux les plus performants ont ensuite été préparés sous forme de nanoparticules pour l’élaboration de films minces de qualité optique afin d’en étudier les propriétés d’adsorption et de co-adsorption (acide acétique/eau) par ellipsométrie. L’incorporation de nanoparticules métalliques plasmoniques a ensuite été effectuée afin de concevoir un capteur colorimétrique. L’objectif final de ce travail est de concevoir un nouveau type d’adsorbant caractérisé par une capacité et une sélectivité d’adsorption élevée et dont on pourrait aisément déterminer le niveau de saturation en acide acétique afin d’anticiper son remplacement et ainsi assurer la préservation des objets stockés et exposés dans les musées
During their storage or their exhibition, the cultural heritage objects undergo physicochemical alteration processes related to their environment and in particular to the action of primary (e.g. sulfur dioxide, nitric oxides), secondary (ozone) pollutants or Volatile Organic Compounds (VOCs). It has been demonstrated that these gases/vapors are involved in hydrolysis and oxidation reactions. Among the most common VOCs encountered in museums, Acetic acid has a significant and recognized role in the deterioration of cultural heritage objects such as photographic films. In order to face this issue, this Ph.D. thesis focused on the design of new porous multifunctional hybrid materials denoted « Metal-Organic Frameworks » (MOFs) for the selective capture of acetic acid in the presence of moisture (40% relative humidity) and at room temperature. The remarkable adsorption properties (sensitivity, selectivity and capacity) and the great versatility of MOFs (hydrophicity/hydrophobicity balance, size/shape of pores,…) were used to preconcentrate selectively the acetic acid in humid conditions. The most performing materials were then prepared as nanoparticles and then used for the elaboration of high optical quality thin films in order to study the coadsorption (acetic acid/water) properties of MOFs by ellipsometry. The incorporation of plasmonic metal nanoparticles was then carried out in order to design a colorimetric sensor. The final objective is to devise a novel type of adsorbent that integrates a high VOC adsorption capacity and selectivity under humid conditions and an easy on-line monitoring of their saturation capacityin order to anticipate its replacement and therefore ensure the preservation of the stored and exhibited objects in museums

This day of age when an increasing demands for better and more environmental friendlymaterial is requested. At the same time is also higher demands on the designers todevelop new products for the future. To design new products which express a futuristicfeeling and a “must-have-feeling”. Therefore is there a need to educate better designersand architects for the future a better knowledge for material. Both for existing designersand architects but also for new designers. To encourage learning and discover newmaterial is new tools important, a tool such as a meeting point in which people meet, talkand discover new materials. A meeting place in which a material library has its naturalplace, a place designers, architects and laymen can visit. The great advantages of a material library is the possibility to touch and feel the materialsamples. To invite people to use their senses and learn about materials. This report focus on how to best build and present a material library in the facility of apublic place. But also how to construct a mobile module used as a tool for education.Each scenario has their own dilemma and needs, for example, in the University library atJönköping has criterion for a module that fits into the regular exhibition. To present newand innovative material samples in a manner that reminds of how people search forbooks on the shelves. For the mobile module is focus more towards presenting material samples used in theproduction today. The presentation is more focus on presenting material samples during alecture in which the teacher stands in front of a class and pointing towards the materialand students are allowed to touch and feel the material samples when they have thepossibility to do so. Besides this will the mobile module also work as mobile storagelocation for each department’s material samples.

Texte intégral
Résumé :
Lorsque le bois est utilisé en extérieur avec des expositions répétées ou permanentes aux humidifications, les risques d’altération par des agents de dégradations biologiques au cours du temps sont élevés. Par conséquent, il est indispensable de recourir à des systèmes de protection afin de garantir une durée de vie optimale. Les produits traditionnels utilisés pendant des décennies et reconnus comme étant les plus efficaces font actuellement l’objet de fortes restrictions en raison de leur toxicité, entraînant leur disparition progressive du marché européen. Le projet FUI TIMBIRDE a eu pour objectif de développer des formulations permettant de greffer chimiquement des polymères sur les hydroxyles du bois afin de réduire son hygroscopie et limiter le relargage du traitement dans l’environnement. De plus, ces traitements ont pour but de diminuer la porosité du bois en la remplissant par la matrice polymère. Pour ce faire, les fonctions chimiques capables de réagir avec les hydroxyles du bois ont été identifiées en utilisant la cellulose comme composé modèle. Ensuite, des polymères hydrophobes ont été fonctionnalisés par ces fonctions d’accroche en vue de leur greffage sur les groupements hydroxyles du bois par la technique du « graft to ». Dans le cadre de cette étude, les formulations retenues ont été appliquées en profondeur dans le bois par imprégnation en autoclave sous vide/pression. Les systèmes imprégnés dans le bois sous forme de latex ont ainsi permis de diminuer la reprise en eau des bois traités (jusqu’à 50%) par rapport au témoin non traité
When wood is used outdoors with repeated or continuous exposures to moisture, degradation by biotic factors is high. Consequently, resorting to systems of protection is essential to ensure an optimal service life. However, some of the traditional wood preservatives, used for decades for wood protection and regarded as the most effective, are currently subjected to severe restrictions in Europe because of their toxicity. The FUI TIMBIRDE project aimed to develop formulations allowing the grafting of non-biocidal polymers on the natural components of wood to limit water uptake and enhance dimensional stability. The grafting of compounds on wood will limit their potential release into the environment and reduce the wood porosity by filling the wood matrix with polymers. In a first step, identification and optimization of grafting functions was performed on cellulose as model compound of wood. Then, hydrophobic polymers were functionalized with these specific functions in order to graft polymers on wood. In this study, wood specimens were treated with selected formulations by vacuum/pressure impregnation in lab autoclave. Thus, a reduction up to 50% of water uptake was observed for wood treated with polymer latex compared to untreated wood

Résumé :
Detection and identification of pesticide residues on objects of cultural heritage is a serious and urgent challenge that currently faces many museums, Native American communities, and private collections worldwide. Organic artifact materials, such as wood, animal hide, basketry, textiles, paper, horn and bone, have traditionally been treated with pesticides to eradicate and prevent infestation by insects, rodents, and mold. These poisonous substances can persist for years in the controlled environment of a museum storeroom and present a potential poisoning risk to people who come in contact with the objects. Surface-enhanced Raman spectroscopy (SERS) has the potential to detect volatile organic pesticides in this context. The technique can overcome the insensitivity of normal Raman spectroscopy and fluorescence interference, and make possible detection of many organic compounds in parts per million concentration. This investigation is aimed at evaluating SERS for the detection and identification of volatiles in museums, with emphasis on naphthalene vapor. The potential of several SERS-active materials; Tollens mirrors, gold film over nanosphere arrays, citrate-stabilized colloidal silver, and nanoporous gold; to detect Rhodamine B and naphthalene is investigated. The research also highlights the mechanisms that underlie SERS, and the relationship between substrate nanostructure and SERS performance.

Résumé :
This paper presents a study of biodegradation and environmental conditions in the library Theses collections and UFSM Compilation in the Central Library of Universidade Federal de Santa Maria/UFSM. Hereby, looking emphasize the importance of the documental preservation, since it can be considered one of the fundamental functions for the conservation of library collections. The research studies the case of the Central Library, and, the environmental problems obtained from the data collections that were made the period from June/2012 to June/2013, by analyzing the existence of microorganisms in the environment and materials, as well as humidity conditions, lighting, ventilation and temperature. The diagnosis was made by direct observation of the situation of collections and through the obtained results it was possible to detect the needs for conservation and preservation of these environments, proposing a plan of actions to contribute to the preservation of documental and cultural heritage in our institution. For this task, were discussed theoretical references relevant to the subject, photographic surveys, as well as the use of a methodology directed to the collection of microbiological agents, being used as a basis for the identification and characterization of microorganisms that are deteriorating the collections. On the evaluation of microbiological contamination in the Library, it was found that fifteen different species of microorganisms were encountered on site. This evaluation was also conducted in a way that were defined the months with the highest incidence of humidity and temperature, getting to the conclusion that, internally, the microorganisms proliferate in greater quantities when there is a sudden change in temperature and humidity in the months from November to January with high temperature and in the months of June and July when there is excessive humidity. During the research, it was found that on the outside of the building, that is, the inner garden, there was more humidity than normal in the months of June, July and August 2012. This was followed by a graphical representation of the environment measurements made through specific instruments. After the identification and evaluation of biological agents that cause biodeterioration, the data were tabulated to evaluate contamination by microorganisms in the environment. The results demonstrate the need to use resources to correct high levels of moisture in the collections analyzed, temperature control and ventilation, as indicated the presence of bacteria and fungi, which could contribute to an unfavorable clinical goers library.It was concluded that regulation of a plan of preventive actions for preserving and conserving the documents would be important to recommend actions for library environment to prevent the appearance of problems that may affect the users and employees of the Central Library from UFSM.
Este trabalho apresenta um estudo da biodeterioração e das condições ambientais nos acervos da Coleção Teses e Coletânea UFSM na Biblioteca Central da Universidade Federal de Santa Maria/UFSM. Por meio deste, procura-se ressaltar a importância da preservação documental, uma vez que pode ser considerada uma das funções fundamentais para a conservação dos acervos de bibliotecas. A pesquisa parte da realidade da Biblioteca Central, isto é, dos problemas ambientais levantados através das coletas de dados que foram efetuadas no período de junho/2012 até junho/2013, por meio da análise da existência de microrganismos presentes no ambiente e nos materiais, bem como as condições de umidade, iluminação, ventilação e temperatura. O diagnóstico foi realizado através de observação direta da situação dos acervos e através dos resultados obtidos foi possível detectar as necessidades para conservação e preservação destes ambientes, com a proposta de um plano de ações contribuindo para a preservação do patrimônio cultural e documental na nossa Instituição. Para a realização deste trabalho, foram abordados referenciais teóricos pertinentes ao assunto, levantamentos fotográficos, como também a utilização de uma metodologia voltada à coleta de agentes microbiológicos, servindo de subsídio para a identificação e caracterização de microrganismos que estejam deteriorando os acervos. Posteriormente, foi realizada a representação gráfica das medições do ambiente, através de instrumentos específicos. Após a identificação e a avaliação dos agentes biológicos causadores das biodeteriorações, os dados foram tabulados a fim de avaliar a contaminação por microrganismos presentes no ambiente. Os resultados obtidos demonstraram a necessidade de usar recursos para a correção de índices elevados de umidade nos acervos analisados, de controle de temperatura e ventilação, pois indicaram a presença de bactérias e fungos, aos quais podem vir a contribuir para um quadro clínico desfavorável aos frequentadores da biblioteca. Há também a necessidade de novos estudos para a verificação de microrganismos em outros materiais, já que os testes apontaram indícios da existência destes nos documentos analisados. Concluiu-se que a regulamentação de um plano de ações preventivas de preservação e conservação documental seria importante para recomendar cuidados com o ambiente do acervo, a fim de evitar o surgimento de problemas que podem vir a afetar o bem estar dos frequentadores e funcionários da Biblioteca Central da UFSM.

Résumé :
The study investigated preservation of, and access to, legal deposit materials at the Msunduzi Municipal Library. Constant access to legal deposit materials will depend on proper preservation methods from the time they are first produced. The focus was to identify how the different materials are preserved and stored, especially because every institution has unique needs, especially with regard to the climatic conditions of the area. The study also examined challenges faced by the depository, skills and knowledge of the depository staff about preventative preservation methods, resources for conservation and collection management strategies. The methods to help make materials accessible were established by examining the means and processes used. Methodological triangulation was used to look at the study in different ways and this included a questionnaire, interviews, observation and collection of graphic data. The units of analysis were the staff of the legal deposit department and the whole population was surveyed. In this study, quantitative and qualitative techniques were employed. The results of the self-administered question and observation schedule were analysed using SPSS. Data collected using the interview schedule was analysed qualitatively. The results of the study show that there are inadequate preservation activities and strategies for legal deposit materials at the Msunduzi Municipal Library. The legal deposit collection was at risk of being lost and inaccessible to present and future generations. This was mostly due to lack of preservation activities and strategies as a result of lack of knowledge in preservation, adequate funding, staff training, preservation policies, environmental control of stack rooms and the proper handling and storage of materials.
