Abstract

Purpose

This paper aims to report the investigation of over heat and mass transfer of convective Casson fluid flow over a moving vertical plate with nonlinear thermal radiation and convective boundary conditions.

Design/methodology/approach

The main partial differential equations of the flow, heat and concentration profiles were rehabilitated to nonlinear ordinary differential equations by using an appropriate similarity transformation. The resultant nonlinear ordinary differential equations (ODEs) are solved numerically applying fourth-order Runge–Kutta shooting technique and functions of ODE45 from MATLAB.

Findings

The effect of convective heat transfer, buoyancy ratio parameter, nonlinear thermal radiation, Prandtl number, Rayleigh number and Schmidt number over velocity, temperature and concentration profiles, equivalent to abundant somatic parameters were graphically scrutinized.

Originality/value

All the results are very promising and further there is got good agreement of results when compared with earlier published results at limiting conditions.

Abstract

Purpose

This paper aims to find the influence of convective heat transfer, buoyancy proportions, nonlinear thermal radiation, Prandtl number, Rayleigh number and Schmidt number on velocity, temperature and concentration profiles.

Design/methodology/approach

This paper explores the heat and mass transfer of a stagnation point stream of free convective Casson fluid over a moving vertical plate with nonlinear thermal radiation and convective boundary restrictions. The governing PDEs of stream, heat and concentration profiles were reformed into an arrangement of nonlinear ODEs by using similarity transformation. This framework was then tackled numerically by applying forth-order RK shooting strategy.

Findings

Distribution of flow, velocity and temperature profiles for different values of governing parameters are analyzed.

Originality/value

The original results are depicted in terms of plots.

Abstract

Purpose

The steady two-dimensional laminar boundary layer flow, heat and mass transfer over a flat plate with convective surface heat flux was considered. The governing nonlinear partial differential equations were transformed into a system of nonlinear ordinary differential equations and then solved numerically by Runge–Kutta method with the most efficient shooting technique. Then, the effect of variable viscosity and variable thermal conductivity on the fluid flow with thermal radiation effects and viscous dissipation was studied. Velocity, temperature and concentration profiles respectively were plotted for various values of pertinent parameters. It was found that the momentum slip acts as a boost for enhancement of the velocity profile in the boundary layer region, whereas temperature and concentration profiles decelerate with the momentum slip.

Design/methodology/approach

Numerical Solution is applied to find the solution of the boundary value problem.

Findings

Velocity, heat transfer analysis is done with comparing earlier results for some standard cases.

Abstract

Purpose

The present paper's purpose is to review the literature related to quality assessment and performance evaluation in academic libraries, whether empirical or theoretical, and to extract key issues. It aims to explore which criteria exert a significant relationship with the academic libraries' performance quality; identify a set of criteria that appears to be useful for assessing the quality of academic libraries ITBS; and use these criteria to develop an instrument or evaluation checklist for evaluating the quality of academic libraries ITBS.

Design/methodology/approach

Related keywords such as “academic libraries research”, “academic libraries evaluation”, “academic libraries assessment” were searched on the web as well as some leading databases. In addition, available library resources as well as online book databases were consulted. Key issues were identified, categorized and discussed to develop the evaluation checklist suggested by the paper.

Findings

A number of indicators have been developed and tested in quality assessment studies debated in the paper. The literature reveals that evaluating ITBS in academic libraries should be considered to a greater extent and thus, more evaluation studies on the basis of validated tools are needed.

Research limitations/implications

The review does not claim to be comprehensive.

Originality/value

The paper can serve as a research roadmap concerning quality assessment of ITBS in academic libraries for researchers, managers, academic authorities and users.

Abstract

Purpose

The main purpose of this investigation is to define the status of the application of information technology in academic libraries located in Kerman, the center and largest city of Kerman Province, Iran, and to understand the problems and difficulties in using information technology in these libraries.

Design/methodology/approach

The survey has covered 17 libraries belonging to Shahid Bahonar University, Kerman Medical University and Islamic Azad University. Two kinds of questionnaires were distributed to libraries – one for librarians and the other for library staff. The findings of the survey have been analyzed using SPSS software.

Findings

Results show that the level of application of information technology in Kerman academic libraries is acceptable but they should improve their status to match with ever increasing demand for better librarian services at universities; the most important problem and serious difficulty is the lack of educated librarians, which needs a suitable investment and planning; and, although about 70 percent of librarians in Kerman academic libraries have participated in related training courses, the most serious difficulty in using information technology is still the lack of educated librarians.

Practical implications

Based on the research findings, several suggestions for improvements can be made, for example: recruitment of multi‐skilled librarians familiar with information technologies related to the mechanism of work in academic libraries; planning and designing ongoing courses of information technology and related skills; promotion and introduction of various academic library services through compiling and publishing manuals and guides; equipping academic libraries with more information technology facilities; having a special budget for development of information technology infrastructure; overcoming telecommunication barriers and shortcomings to better use of information technology; and mechanization of all academic library departments to provide information services more optimally and speedily.

Originality/value

The research studies the rate of using information technologies in Iran as a developing country. Hopefully, uncovering and understanding some unknowns based on such investigations can help to address the digital divide within universities and countries governing them.

Abstract

Purpose

The purpose of this paper is to compare the attitude of the managers of libraries located at Iran, Tehran and Shahid Beheshti Medical Sciences Universities' training hospitals, on the status of information technology (IT) in the mentioned libraries.

Design/methodology/approach

This study employed a researcher‐made questionnaire. The managers of 40 hospital libraries of Iran, Tehran and Shahid Beheshti Universities formed the population of the research. To analyze the collected data, the statistical software SPSS (version 17) was used.

Findings

Results showed that 12.5 per cent of Tehran, 15.6 per cent of Iran and 25 per cent of Shahid Beheshti Universities library managers agreed, to a very large extent, on the application and development of IT and its tools and 93.7 per cent of the managers from all three hospital libraries deemed the application of IT most necessary. The managers believed that the greatest advantage of IT is concerned with the reduction of human efforts (59.4 per cent), and 100 per cent of the managers acknowledged the need for further promotion of their skills in a wide variety of IT issues. In total, 16.1 per cent at Tehran, 12.9 per cent at Iran and 29 per cent at Shahid Beheshti University considerably approved of formal education for the promotion of their librarians' skills.

Originality/value

This study is a step towards acknowledging the contribution, status, and value of hospital libraries to the health sector by the library managers in theory and practice, in the shadow of considering their librarians as network experts, information media and system designers, and technology experts.

Abstract

Purpose

The purpose of this paper is to examine the influence of magnetic field on Williamson nanofluid embedded in a porous medium in the presence of non-uniform heat source/sink, chemical reaction and thermal radiation effects.

Design/methodology/approach

The governing physical problem is presented using the traditional Navier–Stokes theory. Consequential system of equations is transformed into a set of non-linear ordinary differential equations by means of scaling group of transformation, which are solved using the Runge–Kutta–Fehlberg method.

Findings

The working fluid is examined for several sundry parameters graphically and in a tabular form. It is noticed that with an increase in Eckert number, there is an increase in velocity and temperature along with a decrease in shear stress and heat transfer rate.

Originality/value

A good agreement of the present results has been observed by comparing with the existing literature results.

Abstract

Purpose

The purpose of this study was to evaluate the content growth of institutional repositories (IR) in South India and analyse the type-wise growth of items available in these IRs and also discuss the traits and trends exposed by them.

Design/methodology/approach

With the help of Registry of Open Access Repositories and Directory of Open Access Repositories (OpenDOAR), 39 repositories were located in south India. From these, Personal websites, the IRs that are currently not working and the repositories used for journal archiving were excluded. A total of 22 operational IRs at 21 institutions were identified for the study. Within a 15 month period, the data were collected from the 22 IRs twice for monitoring content growth.

Findings

The content of nearly all IRs have grown over the 15 month period, and the overall content growth rate was 7.82 per cent. Journal articles were the important content type of IRs, while thesis and conference papers were the next common. Moreover, item monographs exhibited the highest growth rate. Other categories, conference proceedings, and conference papers also exhibited a high growth rate. The present study revealed that Indian repositories were actively engaged in data curation activities, depositing a wide variety of items in their respective IRs. Overall, South Indian repositories exhibited a slow growth rate and tended to become inactive. Most South Indian Universities had not constituted the IRs, which led to the dominance of English language material in these IRs.

Research limitations/implications

The study was conducted only in South Indian IRs.

Originality/value

This is the first study in India, attempting to determine the type-wise growth of items in IRs.
