Corrosion protection aspects of electrochemically prepared polyfurfural film on low carbon steel
Authors: Grosser F.N. , Gonçalves R.S. 
Published: March 2005

PurposeThis paper describes new experimental evidence of the electropolymerization of furfural on non‐noble metals such as low‐carbon steel. The organic compound (2‐furancarboxaldehyde) was selected because it is easily obtained from biomass and other sources. These results confirm the possibility of synthesizing a polymeric film, with good adherence and stability that provides a new protective barrier against corrosion to this kind of metal.Design/methodology/approachElectrochemical methods such as chronoamperometry, chronopotentiometry and cyclic voltammetry (CV) were used to synthesize and characterize the polymer formed on the electrode surface. Some electrochemical impedance experiments were conducted in order to confirm the electrochemical behavior modification of the electrode, due to the presence of the organic film on the surface.FindingsThe polymer film could be grown galvanostatically, potentiostatically or, during CV. The corrosion protection afforded by polyfurfural (PFy) that had been formed on a low‐carbon steel surface was confirmed by the CV, EIS and polarization curves.Research limitations/implicationsThe possible synthesis of a new polymeric structure on a non‐noble metal is interesting from a practical point of view. However, more experiments are necessary in order to test other organic solvents and other non‐noble metals such as zinc, aluminium, copper, etc.Practical implicationsThe corrosion protection afforded by PFy that had been formed on a low‐carbon steel surface was confirmed by the CV, EIS and polarization curves. Anodic current values associated with metal oxidation decreased when the metal surface was covered with the organic film.Originality/valueThis is the first paper that deals with the electropolymerization of furfural on this type of metal. It was not found in the literature evidences that this polymer was synthesized before.

Authors: Singh Harpreet , Puri D. , Prakash S. 
Published: March 2005

PurposePlasma spray coating technologies are capable of depositing a wide range of compositions without significantly heating the substrate. The objective is to characterise plasma sprayed metallic coatings on a Fe‐based superalloy.Design/methodology/approachNiCrAlY, Ni‐20Cr, Ni3Al and Stellite‐6 metallic coatings were deposited on a Fe‐based superalloy (32Ni‐21Cr‐0.3Al‐0.3Ti‐1.5Mn‐1.0Si‐0.1C‐Bal Fe) by the shrouded plasma spray process. The coatings were characterised in relation to coating thickness, porosity, microhardness and microstructure. The high temperature oxidation behaviour of the coatings was investigated in brief. The techniques used in the present investigation include metallography, XRD and SEM/EDAX.FindingsAll the coatings exhibited a lamellar structure with distinctive boundaries along with the presence of some porosity and oxide inclusions. The microhardness of the coatings was observed to vary with the distance from the coating‐substrate interface. The St‐6 coating had the maximum microhardness, whereas the lowest hardness was exhibited by the Ni3Al coating. The phases revealed by XRD of the coatings confirmed the formation of solid solutions, whereas EDAX analysis of the as‐sprayed coatings confirmed the presence of basic elements of the coating powders. So far as high temperature oxidation behaviour is concerned, all of the coatings followed the parabolic rate law and resulted in the formation of protective oxide scales on the substrate superalloy.Originality/valueThe plasma spray process provides the possibility of developing coatings of Ni3Al as well as commercial available NiCrAlY, Ni‐20Cr and St‐6 powders on Fe‐based superalloy Superfer 800H

Published: March 2005

PurposeTo show the effect of organic compounds containing O and N atoms on the corrosion inhibition of Cu in HNO3 and; the effect of some donating substituent groups on the corrosion inhibition.Design/methodology/approachA range of published papers (1956‐1995), which aim to discuss the effect of organic compounds on the corrosion inhibition process. Two methods were used to determine the rate of corrosion, these methods were weight loss and polarisation. The effect of temperature and concentration were studied. The thermodynamic parameters for the process were computed and discussed.FindingsProvides information about weight loss and polarisation methods and how to prepare the Cu samples before and after tests. This will provide many academics relevant information before teaching or researching duties.Research limitation/implicationsThe paper may be using withdrawing substituting groups in addition to donating groups, this will improve the discussion, also the paper does not use the technique of impedance spectroscopy for comparison.Practical implicationsTo use Cu alloy for comparison and to use other compounds with larger molecular weights.Originality valueThe use of some phthalimide derivatives as corrosion inhibitors for Cu in HNO3, provide more information on Cu corrosion for academic researchers and provide practical help for starting researchers.

Fast surfing, broad scanning and deep diving
Authors: Heinström Jannica 
Published: March 2005

PurposeTo explore information behavior from a psychological perspective by relating information seeking to personality traits and study approaches.Design/methodology/approachThe research design was quantitative and consisted of statistical analysis of three questionnaires, i.e. the NEO Five‐Factor Inventory measuring personality, the ASSIST test measuring approaches to studying, and a questionnaire regarding information behavior. A total of 305 university students who were in the process of writing a Master's thesis responded to the questionnaires.FindingsThree information‐seeking patterns – fast surfing, broad scanning and deep diving – emerged from the statistical analyses. Fast surfing could be related to a surface study approach and emotionality, as well as to low openness to experience and low conscientiousness. Broad scanning was linked to extraversion, openness, and competitiveness, whereas deep diving was a search pattern typical of analytical students with a deep and strategic study approach.Research limitations/implicationsThe results are based on descriptions of behaviour, not actual observations. Although the statistical results were significant, generalisable conclusions would have required more convincing figures. Further research is recommended in order to explore the three search styles in other populations and contexts.Originality/valueInformation‐seeking behaviour has not previously been studied in relation to the five‐factor model, which is regarded as the most modern personality theory to date. Understanding of the psychological reasons behind different information‐seeking styles is important for a holistic view of information behavior. These insights are valuable for researchers interested in user behavior as well as for practitioners like teachers and information professionals.
Towards a procedure model in terminology management
Authors: Kremer Stefan , Kolbe Lutz M. , Brenner Walter 
Published: March 2005

PurposeThere is a lack of efficiency when dealing with information and searching for the right content. Aims to present a procedural model which in essence is a generalized approach to terminology management, with which to build and maintain glossaries and taxonomies.Design/methodology/approachIn addition to an extensive literature review, analysis of three action research cases with several corporate partners is presented. The first case focuses on the introduction of a glossary for a Swiss insurance company. The second illustrates the results from setting up a corporate taxonomy at an international professional services firm. The third case combines glossary and taxonomy for document classification and retrieval.FindingsGlossary and taxonomy are suitable for solving a wide range of terminological defects. Usage and maintenance processes play a central role in the management of terms and should be well defined. Only a well‐suited trade‐off between centralized and decentralized terminology management will be sustainable.Research limitations/implicationsOther means besides clearly defined processes have to be defined to clearly eliminate certain issues. Furthermore, there is the question of whether the implementation of terminology management could benefit certain types of companies in certain industry branches more than others.Practical implicationsConcrete actions that have to be taken into consideration when introducing glossary and taxonomy systems.Originality/valueProposes a procedural model for the introduction of glossary and taxonomy as well as the cultivation of a corporate terminology.
Understanding cultures, and IFLA's Freedom of Access to Information and Freedom of Expression (FAIFE) core activity
Authors: Sturges Paul 
Published: March 2005

PurposeAims to explore an alternative approach to library and information service in multicultural communities, based on the principles of IFLA's Freedom of Access to Information and Freedom of Expression (FAIFE) Committee.Design/methodology/approachLiterature‐based analysis of current approaches to multicultural services and the basis for a different approach.FindingsThe need in information and library services for multicultural communities is often described as if it is solely for members of minority communities to be able to obtain materials in their own languages and cultural traditions. A more considered view stresses the need for access to richly informative resources so that all members of a multicultural society can move towards a deeper understanding of each other. IFLA's FAIFE initiative implies more than just a campaign against the suppression and censorship of information and communication. It implies creating conditions for information access unhindered by prejudices, misconceptions and inadequate competences. FAIFE's role in facilitating removal of restrictions, combating suppression of information, fostering rights of access and supporting the development of information competences in all communities and in the information professionals who serve them, is potentially a major contributor to the enhancement of fair and harmonious relations in multicultural communities.Research limitations/implicationsThere is no new research in the paper: it builds on sources already published.Practical implicationsA modified approach to multicultural library and information services based on FAIFE principles.Originality/valueAddresses providers of multicultural services in libraries.
Democracy, eLiteracy and the internet
Authors: Joint Nicholas 
Published: March 2005

PurposeArgues that the internet has an important contribution to make to the improvement of the democratic process, but that this contribution can only be effective with advocacy and support from information professionals and educators; the cultivation of eLiteracy by such information professionals and educators is vital in delivering the democratic potential of the internet.Design/methodology/approachAn opinion piece based on current and recent trends in thinking about digital citizenship, the internet and democracy.FindingsHopeful initial visions of the impact of internet technologies on democracy have been shown to be in some ways too optimistic. Many of the most notable social impacts of the internet on our collective well‐being have been harmful. The cultivation of eLiteracy as a democratic attribute of citizenship should enable us to make the most of the social beneficent potential of the networks.Research limitations/implicationsPurely an expression of belief about what may prove to be the likely social and political benefits of promoting eLiteracy as an aspect of enhanced citizenship. Offers potential for exploration via more in‐depth research.Practical implicationsOpens up an optimistic social and political purpose to the cultivation of eLiteracy in a broad mass of citizens.Originality/valueAffirms an optimistic view of the democratic potential of the internet, but makes it clear that this potential will not emerge of its own accord. Citizens must engage intelligently with the social and political issues raised by the internet, in particular with the issue of how the new media enable the electorate to conduct dialogue with government. Information professionals have a particular civic duty to be aware of the democratic significance of their promotion of information literacy and, more specifically, of eLiteracy.
Information‐seeking behaviour of undergraduate biology students
Authors: Callinan Joanne E. 
Published: March 2005

PurposeTo understand what differences exist between first year biology and final year biochemistry students in University College Dublin so that measures can be taken to address those needs. It examines student's awareness and use of different sources of information for their course‐work, their use of the (E‐) library, why they visited the university library, the type of assistance they had received in using the library as well as the type of instruction they would like to receive in the future.Design/methodology/approachA questionnaire was designed and administered to both sample groups to investigate the information‐seeking behaviour of these students in different years of their studies.FindingsThe study highlights the positive aspects of seeking information from the student's perspective as well as the barriers they encountered when seeking course‐related information. The findings show that there are differences in the extent to which sources of information are used by students in different years of their studies. Apart from web sites and web‐based lecture notes, lack of awareness is the primary reason why undergraduate biology students did not use the library's electronic databases.Research limitations/implicationsThe study does not distinguish between third and fourth year students in the final year sample.Practical implicationsOne of the key recommendations is that bibliographic instruction should meet the specific information needs of first year biology and final year biochemistry students as well as greater liaison between faculty and librarians in the area of collection development and information literacy.Originality/valueThis paper establishes the importance of a cross‐sectional study in understanding the difference in students' information needs in different years of their studies.

It also provides MARC 21 fields that can be used in coding digital records.Originality/valueThe paper emphasizes the value of team work, planning and assessment for managing cataloguing project.
Copyright law in the European Union, with special reference to Germany
Authors: Beger Gabriele 
Published: March 2005

PurposeTo provide information about how changes to the Copyright Law in the European Union have far‐reaching implications for library services; and in particular to illustrate this by showing how library organizations in Germany have reacted to German legal implementation in such a way that they continue to provide services which their users have come to expect of them.Design/methodology/approachThe mandates of the Copyright Law in the European Union are examined and the problems and positions of the various interest groups in amending the German Copyright Law are presented.FindingsThe presentation shows that German library organizations are striving to help create a legal framework in which the interests of the rightholders, the providers of services for users and the endusers are balanced. With the increased development of electronic means of storage and duplication and the uncertainty of what the future will bring, the fears of loss by the rightholders have created an atmosphere of mistrust, which makes it difficult to create legislation acceptable to all parties.Research limitations/implicationsThe current status of the Copyright Law in Germany is in a state of flux. Depending on the final version of the Law, not only German libraries, but libraries all over the world may find themselves faced with restrictions in international inter‐library loan and thereby be faced with the need to reassess how and if they will be able to offer all the services they have in the past.Practical implicationsAny changes to Copyright Law have far‐reaching effects on the flow of information. Since libraries play an important role as intermediaries between endusers and rightholders, it is imperative that they are aware of the ramifications of any changes to these laws.Originality/valueThe paper examines the background for the current status of the Copyright Law in Germany, presents the positions of the various interest groups, indicates how the flow of information may be affected by any changes and makes a plea for a reasonable solution which will be acceptable to all parties involved.

Published: March 2005

PurposeThis paper reviews some of the applications addressed by a new company that specialises in the integration of sensors on assembly plants.Design/methodology/approachThe company's expertise encompasses mechanical, electrical and electronic and optical engineering, and it is able to provide complete solutions, using off‐the‐shelf and bespoke elements as necessary.FindingsThe ability to integrate standard products from different suppliers gives Complete Sensing Solutions Ltd an edge over any single sensor producer. Its further skill in manufacturing bespoke elements – whether software or hardware – also gives it the unique advantage of providing complete systems.Originality/valueBrings to the attention of production managers the existence of a sensor specialist able to design, build, integrate and install equipment on the plant.
Swiss collaboration yields novel, automated micro‐optic assembly technique
Authors: Bogue Robert W. 
Published: March 2005

PurposeThis describes a new automated assembly technique, developed by Leica Geosystems and the Swiss Federal Institute of Technology, which allows the automated precision assembly of miniature optical components and subsystems.Design/methodology/approachDubbed TRIMO‐SMD (three‐dimensional miniaturised optical surface‐mounted device), this new technique is designed for use with optical components of around 2 mm in diameter such as laser diodes. It uses six‐axis robotic motion, automated optical alignment with cameras and position sensors and laser‐reflow soldering to assemble photonic modules.FindingsThis development has been commercialised and is being used in a production environment by Leica Geosystems. It fixes the optical element into position in just 2 s and the placement accuracy of each component is repeatable to within 1 μm.Practical implicationsThis technique has allowed novel micro‐optical assemblies to be produced automatically and has improved the performance and reduced the size and weight of certain precision optical products such as laser rangefinders and Lidar transceiver modules.Originality/valueThis is a new technique which, by allowing the automated, precision assembly of miniature optical components, will benefit companies involved with the manufacture of optical sensing, telecommunications, medical and other products.
Novel visual sensing systems for overcoming occlusion in robotic assembly
Authors: Kim J.Y. 
Published: March 2005

PurposeIn precision robotic assembly visual sensing techniques have been widely used since they can detect large misalignments and also part's shape at a distance. Develops two novel visual sensing methodologies.Design/methodology/approachBoth systems consist of four components: an inside mirror and an outside mirror, a pair of plane mirrors and a camera with a collecting lens. The difference between the two is that system A adopts a pyramidal mirror configuration, while system B employs a conic one. Owing to this configuration difference, system A can detect three‐dimensional measurements of objects with only one image capture, while in addition to this functionality system B is shown to be capable of detecting two omni‐directional image. The measurement principles are described in detail and compared with each other.FindingsThe image acquiring process is shown to easily detect the in situ status of each assembly action, while the recognition method is found to be effective to identify instantaneous misalignment between the peg and the hole. The results obtained from a series of experiments show that the proposed visual sensing methods are an effective means of detecting misalignment between mating parts even in the presence of self‐occlusion.Practical implicationsThe proposed sensing methods will dramatically increase the rate of success when actually utilized in assembly processes.Originality/valueDescribes the development of two novel visual sensing methodologies.
