Abstract
With the ever‐increasing developments in information technology and networks, end users of the online environment now have integrated access to a variety of bibliographic databases, mainly library catalogues and A&I services, from a single terminal. While such a facility influences users’ expectations and preferences in the searching, retrieval and presentation of bibliographic information, it raises an important question as to whether different bibliographic practices can use a similar or compatible set of principles for creating bibliographic records and files. This paper is an attempt to identify areas of possible reconciliation and also address some of the implications of such an issue.

Abstract
Purpose
In this paper, the forced convection heat transfer of the nanofluid composed of water and AL2O3 nanoparticles is simulated in a two-dimensional horizontal microchannel by injecting the lower wall. The upper wall of the microchannel is 303 K at temperature TH. On the lower wall of the microchannel, there are three holes for flow injection. Other parts of the wall are insulated. In this paper, the effect of parameters such as Reynolds number, slip coefficient and volume fraction of nanoparticles is investigated.
Design/methodology/approach
The boundary condition of the slip velocity is considered on the upper and lower walls of the microchannel. In this work, the flow of nanofluid in the microchannel is considered to be slow, permanent and Newtonian. In the present study, the effect of injection through the microchannel wall on the slip velocity is examined for the first time.
Findings
The results are also presented as velocity profiles and Nusselt number diagrams. It was found that the Nusselt number increases with increasing the amount of slip coefficient of velocity and the weight percentage of solid nanoparticles. The rate of this increase is higher in the high values of the Reynolds number.
Originality/value
A novel paper concerned the simulation of cross-flow injection effects on the slip velocity and temperature domain of a nanofluid flow inside a microchannel.
