Published: December 2018

Removing carbon dioxide is important for the upgrading of biogas or natural gas into compressed or liquefied methane, and adsorption-driven separation of CO2 could be further advanced by developing for example new adsorbents. Zeolite adsorbents can select CO2 over CH4, and we here confirmed that the adsorption of CH4 on zeolite |Na12-xKx|-A was significantly lower for samples with a high K+ content, i.e. x > 2. Nevertheless, these samples adsorb CH4 after long equilibration times as determined with 1H NMR experiments. To assess further the intracrystalline diffusion of CH4 in these zeolites, pulsed-field gradient NMR experiments were performed. In large crystals of zeolites |Na12-xKx|-A, the long-time diffusion coefficients of CH4 did not vary with x, and the mean square displacement was about 1.5 mm irrespective of the diffusion time. Also for zeolite |Na12|-A samples of three different particle sizes (~0.44, ~2.9, ~10.6 mm), the mean-square displacement of CH4 was 1.5 mm and largely independent of the diffusion time. This similarity provided further evidence for an intracrystalline diffusion restriction for CH4 within the medium- and large-sized zeolite A crystals, and possibly of clustering and close contact among the small zeolite A crystals. The long-time diffusion coefficient of adsorbed CH4 was (at 1 atm and 298 K) about 1 ´ 10–10 m2/s irrespective of the size of the zeolite particle or the studied content of K+ in zeolites |Na12-xKx|-A and |Na12|-A. The T1 relaxation time for adsorbed CH4 on zeolites |Na12-xKx|-A with x > 2 was smaller than for those with x < 2, indicating that the short-time diffusion of CH4 was hindered.

Published: December 2018

Phase control in the self-assembly of metal-organic frameworks (MOFs) – materials wherein organic ligands connect metal ions or clusters into network solids with potential porosity – is often a case of trial and error. Judicious control over a number of synthetic variables is required to select for the desired topology and control features such as interpenetration and defectivity, which have significant impact on physical properties and application. Herein, we present a comprehensive investigation of self-assembly in the Fe-biphenyl-4,4'-dicarboxylate system, demonstrating that coordination modulation, the addition of competing ligands into solvothermal syntheses, can reliably tune between the kinetic product, non-interpenetrated MIL-88D(Fe), and the thermodynamic product, two-fold interpenetrated MIL-126(Fe). DFT simulations reveal that correlated disorder of the terminal anions on the metal clusters in the interpentrated phase results in H-bonding between adjacent nets and is the thermodynamic driving force for its formation. Coordination modulation slows self-assembly and therefore selects the thermodynamic product MIL-126(Fe), while offering fine control over defectivity, inducing mesoporosity, but electron microscopy shows the MIL-88D(Fe) phase persists in many samples despite not being evident in diffraction experiments, suggesting its presence accounts for the lower than predicted surface areas reported for samples to date. Interpenetration control is also demonstrated by utilizing the 2,2'-bipyridine-5,5'-dicarboxylate linker; DFT simulations show that it is energetically prohibitive for it to adopt the twisted conformation required to form the interpenetrated phase, and are confirmed by experimental data, although multiple alternative phases are identified due to additional coordination of the Fe cations to the N-donors of the ligand. Finally, we introduce oxidation modulation – the concept of using metal precursors in a different oxidation state to that found in the final MOF – as a further protocol to kinetically control self-assembly. Combining coordination and oxidation modulation allows the synthesis of pristine MIL-126(Fe) with BET surface areas close to the predicted maximum capacity for the first time, suggesting that combining the two may be a powerful methodology for the controlled self-assembly of high-valent MOFs.

Published: December 2018

Diyabetik maküler ödem (DMÖ), diyabetik retinopatinin görme kaybı ile sonuçlanan en önemli komplikasyonlarından biridir. Dünya genelinde, yılda 100.000’den fazla olguda yasal körlüğe neden olduğu bilinmektedir. Bu bakımdan ele alındığında hastalık ciddi bir halk sağlığı sorunudur. DMÖ tanısında standardizasyonun sağlanması, doğru olgularda tedavi kararı verilmesi hasta kayıtlarında ortak bir dil kullanılması açısından gereklidir. Early Treatment Diabetic Retinopathy Study (ETDRS) Grubu’nun önerdiği tanı kriterleri, gelişen görüntüleme yöntemlerinin katkısı ve hastalık hakkındaki bilgilerimizin daha ilerilere taşınması nedeniyle, bugün için önemini büyük ölçüde yitirmiştir. Oftalmolojideki teknik gelişmelere paralel, DMÖ tanı ve takibinde kullanılan yöntemlerdeki gelişim süreklilik arz etmektedir. Fundus biyomikroskopisi, renkli fundus fotoğraflaması, fundus floresein anjiografi ve optik koherans tomografi (OKT) klinik pratiğimizde en sık kullandığımız ve gelenekselleşmiş yöntemlerdir. Fundus otofloresans, mikroperimetri, tarayıcı laser oftalmoskopi ve OKT ile ölçülen retinal kalınlık haritalamaları yeni yöntemler olmamalarına rağmen, ilave özelliklerle DMÖ tanı ve takibinde kendilerine kullanım alanı bulan geleneksel yöntemlerin yeniden yorumlanmış halleri sayılabilir. Yeni yazılım ve donanım eklentileri ile zenginleştirilen polarizasyon duyarlı OKT, en face OKT, OKT anjiografi ve adaptif optik görüntüleme ise muhtemelen DMÖ tanı ve takibinde gelecekte daha çok kullanılacak olan yeni görüntüleme yöntemleridir. Gerek mevcut az kullanılan yöntemlerin DMÖ’deki kullanım alanının genişlemesi gerek tanımlanmış yeni yöntemler, DMÖ ile ilgili bilgilerimizi artırmamız ve daha etkin tedavi sağlamamıza katkıda bulunacaktır. Bu çalışmada amacımız, DMÖ tanı ve takibinde kullanılan geleneksel yöntemler, ilave modifikasyonlarla kullanılmaya başlanmış yöntemler ve yeni görüntüleme yöntemleri hakkında bilgi vermektir.

Мета. Визначити особливості морфологічних змін у підшлунковій залозі (ПЗ) після резекційних втручань із застосуванням високоенергетичних електрохірургічних інструментів (ВЕЕХІ) та стандартної хірургічної техніки.

Матеріали і методи. В умовах експерименту виконували резекцію ПЗ білим лабораторним щурам, використовуючи стандартну хірургічну техніку та ВЕЕХІ в режимі зварювання (DA2), біполярному та монополярному режимах. Гістологічно ПЗ досліджували безпосередньо після виконання операції та через 3, 7 і 21 добу, застосовуючи світлооптичний мікроскоп Leica DМ500.

Результати. Після застосування стандартної хірургічної техніки в ранні строки виникало більш виражене запалення та швидше збільшувався об’єм новоутвореної сполучної тканини, ніж після використання електрохірургічних методів. Після всіх видів електрорезекції в новоутвореній тканині формувались протоки, чого не спостерігали після використання стандартної техніки. Після біполярного зварювання резектована поверхня мала менше крововиливів, ніж після використання хірургічних ножиць. Після резекції, виконаної з використанням монополярного зварювання, утворювався менш щільний коагуляційний прошарок, ніж після резекції, виконаної з використанням біполярного зварювання, а через 21-у добу в зоні резекції формувався значно більший об’єм сполучної тканини та зберігалися більш виражені ознаки запалення, ніж після використання біполярного методу.

Висновки. У разі використання всіх видів електрорезекції скорочується тривалість виконання оперативного втручання, зменшується ризик виникнення кровотечі, на резектованій поверхні утворюється герметичне з’єднання, не ускладнюючи процесів відновлення.

As equações de chuvas intensas são um dos meios mais utilizados para obtenção das estimativas de vazões de projeto aplicadas no dimensionamento de obras hidráulicas. No entanto, devido a escassez de dados pluviométricos em determinadas regiões do país, a determinação dessas equações fica por vezes comprometida, dificultando a determinação de chuvas de projeto. O objetivo principal deste trabalho é utilizar um método de interpolação matemática, inverso do peso da distância – IDW, para espacialização dos parâmetros de equações de chuvas intensas para a Região Metropolitana do Recife (RMR) e Município de Goiana, a partir de 17 estações pluviométricas representativas e estrategicamente localizadas. Como resultados são apresentados mapas de distribuição espacial para cada um dos parâmetros de equações de chuvas intensas da RMR, possibilitando o cálculo de uma precipitação associada a uma duração e a um tempo de retorno para qualquer local da RMR. Foi ainda realizada a verificação do erro entre as intensidades calculadas e parametrizadas para validação do estudo. Sendo também representados mapas de distribuição ao desconsiderar a Estação de Camaragibe, para deste modo realizar a avaliação dos erros percentuais envolvendo tal análise, onde, neste caso, os mesmo se apresentaram baixos, variando de 0,05 até 5,43%.A B S T R A C TIntense precipitation equations are one of the main ways to obtain the design flow estimative applied to the design of hydraulic structures.

The Cedars Project
Authors: Jones Maggie
Published: December 2018

Digital Preservation has become such a pressing issue for libraries world-wide that it is easy to forget what an unknown quantity it was when the Cedars project began in 1998. The Final Report from the RLG/CPA Task Force on Digital Archiving was released in 1996 and this provided a catalyst for further action within the U.K. The Cedars Project was initially funded for three years as part of the final phase of the UK eLib project. An additional year was subsequently funded to enable consolidation and wider dissemination of its findings. The Cedars project made a significant contribution to digital preservation and was able to forge good working relationships with colleagues working in related areas. It delivered both heightened awareness of digital preservation as a critical strategic issue at the broad level, as well as some specific deliverables designed to provide practical support at the operational level. Now that the Cedars project has ended, the primary responsibility within the UK for ensuring the momentum is not lost will rest with the recently formed Digital Preservation Coalition. Significant developments overseas will also feed into the global digital preservation agenda.

Authors: Howley Sue , Ede Stuart
Published: December 2018

Resource commissioned the Wider Information and Library Issues Project (WILIP) to discover what challenges are facing the library and information domain, what needs to be done to tackle them, and what role Resource should take in helping to develop and promote strategies for action. In the initial consultation phase of WILIP practitioners identified a number of generic themes. Improved access for users was the primary goal with better advocacy, more effective funding - especially to sustain initiatives - workforce development and building a strategic framework as the key means of achieving it. Many respondents believe better focused, very practical research is essential to provide a coherent body of evidence to support the case for developing libraries and information services as a major component of the Knowledge Society.

All materials created over the lifetime of this project will be published under a Creative Commons licence, and made available to be used and adapted by library professionals across Scotland. This article outlines some of the ideas and observations that fed into our successful proposal, and sets out our plans for achieving key outcomes of the Libraries R 4 Learning project.
School students, information retrieval and transfer
Authors: Herring James Edward
Published: December 2018

This study sought to examine the views of students, teachers and teacher librarians on students' attitudes to, use of, and reflections on, information retrieval, when completing curricular assignments. A second element of the research was to investigate the views of students, teachers and teacher librarians on the extent to which students might transfer information retrieval skills across time and across subjects. The research was carried out in three rural Australian schools. A constructivist grounded theory approach was taken in the study, and data was collected in the form of student diaries and questionnaires, and interviews with students and staff. Constructivist grounded analysis was used to analyse and interpret data. Findings from the study indicated that a minority of students both valued and would transfer information retrieval skills; the majority of students valued information retrieval skills but were unlikely to transfer skills without prompting; and a very small minority of students could not understand the concepts of information retrieval and transfer. The study also found that the schools lacked a culture of transfer.

Authors: Ferguson Rona , Crawford John
Published: December 2018

This research evaluates the use made of LIS by

researchers at Glasgow Caledonian University with a

view to effecting improvements where appropriate.The

interview method was used. As a result of the study

electronic requesting of inter library loans has been

introduced and special Library web pages for

researchers are now available. The need for cooperation

between the Library and the Research and

Commercial Development Office was recognised. The

research methodologies of researchers was found to

be extremely variable and often unsophisticated. Direct

contact with the Library is in decline.

Authors: Coles Colette
Published: December 2018

Explores the results of interviews with 301 public

library users regarding users' attitudes to IT and

levels of IT literacy. Attitudes averaged 47%

positive, 30% negative and 23% neutral. Other

views concerned the impact of technology on work,

children and quality of life. Library users displayed

varying levels of IT literacy. Six types of users were

identified: non-users (technophobes);

reluctant/anxious; work-related; casual/occasional ;

experience/regular and high flyers (technophiles). lt

The CLA HE Trial Scanning Licence - how we're using it.
Authors: Delasalle Jenny
Published: December 2018

The Copyright Licensing Agency (CLA) Higher Education (HE) Trial Scanning Licence has been implemented to varying degrees across UK HE institutions. The UK HE community has sought to share expertise in the technical, practical and compliance issues associated with the licence since its introduction. The University of Warwick Research and Innovation Unit (RIU) conducted a survey of scanning practice which revealed different approaches and levels of scanning in evidence. This, taken with the CLA's own data about how the licence has been used, presents a picture of how UK HE Institutions are providing electronic extracts to their students. Issues such as who is using the licence, how much they are scanning, what the nature of that scanned content is and how they are creating scanned extracts, reveal much that can help those considering whether and how to use the CLA HE Trial Scanning Licence.
A comparative study of marketing management in British and German university libraries (PhD Thesis)
Authors: Cockrill Antje
Published: December 2018

Within the last decade, the environment in which university libraries operate has dramatically changed. The rise of Conservative Governments in both Britain and Germany and the resulting shifts in public policy as well as the declining economic situation have led to a drastic decrease in resources. Librarians have had to find ways to cope with fewer funds in an environment which is growing ever more competitive. A useful tool for increasing the effectiveness of a library is marketing management. Marketing management is a means to achieve effective financial management, to use existing resources more efficiently and to create new resources in a customer-centred and market-oriented

way.
Review Article
Authors: Coles Colette , Sumsion John
Published: December 2018

This is a remarkably successful enterprise and a

splendid example of 'how to do it right' in so

many ways. As a reference book it compiles a

fantastic amount of information useful to IT

practitioners and library managers' As a

collection of statistics it provides solid evidence

for the history of public library automation in the

1980s and 1990s. To keep policy makers' feet on

the ground it provides essential information on

which electronic materials and services have

already been taken up by public library users'

The combination of these three goals in a single

volume works excellently: the whole is so much

more valuable and exciting than would be a more

'logical' separation into parts. The fact that this is

number six in a series of comparable data

stretching back to 1984 makes it possible to see

the historical context clearly. Chris Batt is

personally responsible for this continuity: he

deserves the gratitude and encouragement of the

whole profession.
BILI: Building Information Literacy in Ireland
Authors: Connolly Amy , Curran Lorraine , Lynch Áine , O’Shea Sile
Published: December 2018

Although information literacy (IL) practice has long been evident in Irish libraries, it was 2008 before the Working Group on Information Literacy (WGIL) published the first Irish national, cross-sector review. In 2012, we built on this research in order to (1) revisit the WGIL case studies and examine how IL was evolving, (2) consider the wider IL context in Ireland, and (3) examine innovations among international bodies supporting IL practice.

Nine international experts and seventeen Irish experts contributed to interviews and surveys. This article focuses on the Irish findings. Revisiting case studies demonstrated that IL remains a priority for the majority despite the economic recession. Wider themes uncovered include embedding IL in the curriculum and workplace, e-citizenship, continuing professional development and advocacy.

Recommendations centre on a two-tiered approach to IL development: a practitioner-led community of practice that facilitates communication and collaboration, and a high-level advocacy committee that fosters a holistic national strategy.

"The love in the room": Evaluating the National Year of Reading in an Australian public library
Authors: Reynolds Sue , Welch Bernadette
Published: December 2018

This study was influenced by research into the impact of the UK National Year of Reading in 2008 using the Generic Social Outcome Framework from the Museums, Libraries and Archives Council. In 2012 a National Year of Reading was held in Australia which offered another opportunity to investigate the nature of impact. While formal evaluation processes were put into place at the national level, our study was a small-scale qualitative research project which considered the evaluation of impact related to National Year of Reading activities at one urban public library service. Data collected included focus group interviews with library staff, as well as desk data from the library service. The findings suggest that it is necessary to give due consideration to impact measures and collection of appropriate data at the planning stages in order to evaluate impact effectively. Measuring impact is much more difficult but ultimately more worthwhile than that of measuring output. The evaluation of impact is an important tool in strategic planning and advocacy and new ways of measurement need to be incorporated into planning and management.
An evaluation of phenomenography
Authors: Cossham Amanda F.
Published: December 2018

This article briefly evaluates phenomenography as a research approach. Drawing on findings from a recently-completed research project, it explains the phenomenographic approach, outlines how it was used in the research project, and presents the advantages and disadvantages of phenomenography. It identifies three issues with using phenomenography that do not seem to have been raised elsewhere. Two issues apply generally to all such research: the nature of phenomenographic data, and an inconsistency in phenomenography itself. The third is around mental models and phenomenographic conceptions and applicable to this research project, but has wider implications for the concept of mental models in the cognitive viewpoint of library and information studies (LIS) research.
Os desafios para a implementação de um Tribunal Constitucional brasileiro
Authors: Gubert Roberta Magalhães
Published: December 2018

O presente artigo tem por objetivo abordar a questão dos modelos de justiça constitucional e debater a (in)existência (e a necessidade de implantação) de um verdadeiro Tribunal constitucional em solo brasileiro. O trabalho está dividido em duas partes; na primeira apresenta os modelos de justiça constitucional – da Suprema Corte norte-americana e dos Tribunais Constitucionais europeus – e, na segunda, apresenta o modelo brasileiro. Por fim, conclui que a ausência de certos traços – como a separação orgânica e institucional do Tribunal Constitucional da estrutura do Poder Judiciário, a competência exclusiva e concentrada para o contencioso constitucional, bem como as diferenças quanto a forma de provimento dos cargos e a permanência na Corte por mandato com prazo determinado – comprovam o distanciamento que existe entre o Supremo Tribunal Federal e as Cortes Constitucionais européias.
Indigenous rights to defend land and traditional activities
Authors: Apostolos Tsiouvalas  , Margherita Paola Poto
Published: December 2018

One of the largest remaining unexploited iron ore deposits in Europe is the Kallak Iron Deposit in the province of Norrbotten in northern Sweden, where a significant Sámi population is located. Since 2011, the UK-based company, Beowulf Mining, has begun a large campaign for extraction in northern and southern Kallak. However, the Sámi of the region, together with environmentalists and non-Sámi individuals have drastically expressed their opposition blocking with various ways the processes. The Sámi being aware of the environmental risk have concerns about their ability to drive reindeer across the land, and the impact Beowulf’s operations are likely to have on the reindeer migratory patterns. Nowadays, seven years after the initial application for licensing, the approval of the application is still pending and Beowulf is pressing more and more the Swedish authorities for a final response in order to start extracting. Only the County Administrative Board of Norrbotten, despite its initial consent, still advocates for Sámi and their reindeer refusing to issue licensing for the British company. Accordingly, this article was designed as a descriptive study of the legal framework of the implementation of this endeavour addressing the legal arguments of both sides as they derive from a qualitative study of official documents, environmental reports, and relative articles of scholars. Concluding, the article illustrates the gaps of legal protection of indigenous land-rights in Sweden presenting their vulnerability to such kind of challenges.

Labor Market Flexibility: Advantages for Workforce or Threat?
Authors: Nugroho Alih Aji
Published: December 2018

Labor Market Flexibility (LMF) which is supported by the law of supply and demand are considered capable of creating an eﬃcient labor market. As well as apprenticeship programs were considered to improve the quality of the labor force which can suppress the number of unemployed. Whether the application of LMF can be a positive impact like as imagined by its proponents? This is the result of research that seeks to see the dynamics of industrial relations faced by the workforce under the LMF system and dismantle the neoliberal project of the apprenticeship system. The study was conducted during September-November 2016 in the industrial area of Bekasi. The study used a descriptive qualitative approach. Collecting data through participatory research or live in. Searchable data sources using methods of a snowball eﬀect. In the end, this study involved seven trade unions, six companies, two foundations labor brokers, three government agencies, 35 workers (10 contract workers, 10 workers outsourcing, and 15 workers apprenticeship) and three labor activists. The result is the implementation of contract system and outsourcing many violate the rules. In the industrial area of Bekasi composition flexible workforce of more than 50% of the total workforce. And under the LMF system occurs bureaucratization in industrial relations. In addition, LMF policy does not reduce unemployment but only rotate unemployment. and the apprenticeship system is expected to increase human resources in the labor force application only used by the owners of capital to get cheap labor.

Digital 3D geometric models have become a central tool for geo-information. For many participatory and collaborative applications, distributing these models easily is essential. Several technical solutions exist for creating online systems that facilitate the study of 3D models in the context of the built environment. To provide an overview on browser based interactive 3D visualizations, we present a set of existing systems applied in Finland, and discuss their common properties and differences. To obtain first-hand experience, we experiment with an online 3D application development platform. The systems studied show a high potential for browser based 3D applications: interactive visualizations with multi-user characteristics and dynamic elements can be built by leveraging the 3D web technologies. Finally, we suggest a framework for discussing browser based 3D systems, covering the spectrum of possibilities available in modern web-based 3D for built environment applications.
Samoprocjena profesionalnih kompetencija studenata ranoga i predškolskog odgoja i obrazovanja u provođenju likovnih i glazbenih aktivnosti s djecom
Authors: Herzog Jerneja , Bačlija Sušić Blaženka , Županić Benić Marijana
Published: December 2018

Likovna i glazbena umjetnost podržavaju emocionalni, kognitivni i psihomotorni razvoj u ranom djetinjstvu. Odgojitelji zato moraju imati dovoljne kompetencija da bi potaknuli sudjelovanje djece u umjetničkim aktivnostima pa je cilj ovog istraživanja bio ispitati kompetencije u umjetničkom području studenata u inicijalnom obrazovanju učitelja. U istraživanju su sudjelovali studenti treće godine ranog i predškolskog odgoja i obrazovanja Učiteljskog fakulteta, Sveučilišta u Zagrebu te Pedagoškog fakulteta, Sveučilišta u Mariboru. Ispitanici koji su završili gimnaziju su bolje procjenjivali svoje profesionalne kompetencije izvođenja glazbenih aktivnosti u odnosu na ispitanike koji su završili umjetničku srednju školu. Ispitanici koji su završili gimnaziju bolje su procjenjivali svoje kompetencije planiranja likovnih aktivnosti, ali ispitanici koji su završili srednju umjetničku školu bolje su procjenjivali svoje kompetencije izvođenja likovnih aktivnosti.
