Abstract
With precursor software dating to 1972, multi‐LIS became the first commercially available, fully integrated library system in North America to run on the Unix operating system. In 1988, multiLIS developers, Sobeco Ernst & Young Inc. (SEY), ported multiLIS software to the MIPS Reduced Instruction Set Computer (RISC) processor, making it the First fully integrated software program to be available on a RISC platform. multiLIS fully supports both CAN/MARC and USMARC as well as the monographs specifications of UNIMARC. As the multiLIS software was developed in a resource‐sharing environment, consortiums are a natural market for the multiLIS product.

Abstract
Purpose
The purpose of this paper is to discuss economic and social issues of contemporary capitalism through the views and works of Grazia Ietto-Gillies who has a long experience of research in these fields. The issues relate to strategies of TNCs, to globalization and transnationalization, to internationalization indices, to linkages between innovation and internationalization, to uneven development, and, finally, to issues related to the economics profession and the dissemination of research in the twenty-first century.
Design/methodology/approach
In-depth interview; use of relevant literature to support statements by interviewer and interviewee; qualitative analysis of issues discussed.
Findings
The article links together under the same theoretical umbrella the following issues: a theory of TNCs based on strategic approach towards labour, governments and suppliers; the development of an internationalization index based on the geography of TNCs' networks; and the possible impact of internationalization on innovation. Uneven development is linked to current problems in Europe. The need and opportunity to reconsider the economics profession and the peer review system in the digitalization era is presented.
Research limitations/implications
The article is based on the views of the interviewer and the interviewee. Their views are backed by their own previous research as well as by research by other scholars cited in the article.
Practical implications
The interview draws policy implication in relation to TNCs and other actors who interact with them such as labour and governments. There are also policy implications in the economic and social spheres regarding the implications of TNCs' strategies and the aftermath of the 2007/2008 crisis.
Originality/value
At the methodological level the article highlights the advantages of in-depth interviews. Specifically, it allows the interviewee to give an overall perspective on her research and to show how the various strands are connected and how they developed through the decades of her research. It allows both interviewer and interviewee to link the issues to a variety of literatures in the economics, sociology and politics fields.

Abstract
Civil engineering index ‐ The latest major file of trade catalogues in microform to be published is ‘Construction and civil engineering index’ by Technical Indexes Ltd (NLW February 1982). Although some of us are more familiar with the very efficient ti cartridge catalogues, this new index comes on microfiche on a reduction of 24x. The file is updated quarterly, contains over 4000 product references, and is classified by the CI/sfB—that is the widely used construction industry classification imported in the early 'sixties by the Royal Institute of British Architects from Sweden; the ‘sfB’ comes from the Swedish ‘Samar Betskommitten Sör Byggnadsfragor’ which is the name of the committee set up in Sweden in 1947 to produce the scheme. Technical Indexes have published a brochure giving further details of the index and catalogues. The total annual cost of the service is about £1500, but it is possible to purchase particular sections separately. For further information, contact Kevin Brennan, Technical Indexes Ltd, Willoughby Road, Bracknell, Berkshire RG12 4DW, tel 034426311, tx 849207.

Abstract
Purpose
The purpose of this paper is to investigate the driving mechanisms for crack propagation regarding the related microstructures. Cracks in white etching layers have been found at the surface of submerged steel blades subjected to frictional sliding conditions.
Design/methodology/approach
In-situ monitoring revealed a fluctuation between mixed lubrication and hydrodynamic lubrication conditions. One lamella including a crack tip was prepared for transmission electron microscopy (TEM) using focused ion beam milling. Transmission electron microscope analysis was performed with the aim to understand the characteristics of the crack propagation, especially considering the influence of the microstructural configuration (grain refinement, carbides, martensite and ferrite grains).
Findings
The investigations have shown a grain-refined plastically deformed layer (friction martensite with grain sizes of < 100 nm) which influences the propagation direction of cracks introduced at the frictionally stressed surface. Thereby, the crack propagation is dominantly parallel to the margin of the grain-refined martensitic layer at the surface and the base material. Cracks were split into side cracks what mostly appears at present carbides. In this case, the crack propagation might strike through the carbide or separate it from the matrix due to the mechanical misfit.
Originality/value
For obtaining the results of this paper, a very special preparation of tribologically stressed samples was performed. Accordingly, specific findings of the crack propagation behavior under such conditions were achieved and are documented in the presented work. Moreover, the described crack propagation process is a combination of several mechanisms which occur in very limited region underneath the surface and are investigated by high-resolution TEM.

Abstract
Purpose
To find the optimal number of channels of rocket engine thrust chamber, it was found that the optimal channel number is 335, at which the cooling effect of the thrust chamber cooling channel reaches the best, which can be helpful to design rocket engine thrust chamber.
Design/methodology/approach
The commercial computational fluid dynamics (CFD) software FLUENT with standard k‐ε turbulent model was used. The CFD method was validated via comparing with the available experimental data.
Findings
It was found that both the highest temperature and the maximal heat flux through the wall on the hot‐gas side occurs about the throat region at the symmetrical center of the cooling channel. Owing to the strong curvature of the cooling channel geometry, the secondary flow reached its strongest level around the throat region. The typical values of pressure drop and temperature difference between the inlet and exit of cooling channel were 2.7 MPa and 67.38 K (standard case), respectively. Besides an optimal number of channels exist, and it is approximately 335, which can make the effect of heat transfer of cooling channels best with acceptable pressure drop. As a whole, the present study gives some useful information to the thermal design of liquid rocket engine thrust chamber.
Research limitations/implications
More detailed computation and optimization should be performed for the fluid flow and heat transfer of cooling channel.
Practical implications
A very useful optimization on heat transfer and fluid flow in cooling channel of liquid rocket engine thrust chamber.
Originality/value
This paper provides the performance of optimization on heat transfer and fluid flow in cooling channel of liquid rocket engine thrust chamber, which can make the effect of heat transfer of cooling channels best with acceptable pressure drop. As a whole, the present study gives some useful information to the thermal design of liquid rocket engine thrust chamber.
