Abstract

Purpose

This paper aims to provide an overall picture of the application of Web 2.0 technologies in Chinese university libraries. The focus of the research is what types of Web 2.0 technologies were applied in such libraries as well as their function and user interface.

Design/methodology/approach

The top 30 Chinese university libraries were selected to investigate the application of Web 2.0 technologies. Content analysis was used in terms of quantitative approach. Data were collected by accessing these 30 university libraries web sites within five weeks.

Findings

Two‐thirds of Chinese university libraries deployed one or more Web 2.0 technologies. Only one‐tenth of libraries adopted more than four Web 2.0 technologies. RSS was the most widely applied, while Wiki was the least. The application of Web 2.0 technologies among Chinese university libraries was not extensive and profound enough.

Research implications

The findings can be utilized to evaluate the status of Web 2.0 technology applications. The statistical data are very useful and authentic sources for improving the level of Web 2.0 technology application. It may enable future research to analyze other aspects (e.g. the application of RSS or Blogs for services).

Originality/value

This unique study explores the application of Web 2.0 mainly in Chinese university libraries that deployed any types of Web 2.0 technologies. This study is very useful for Chinese university libraries in evaluating/deploying Web 2.0. Library managers, librarians, and other libraries may also find this helpful, once they decide to implement such technologies in their libraries.

Abstract

Purpose

The purpose of this paper was to study some effective evaluation methods for the biocide performance on sulfate-reducing bacteria (SRB) biofilm.

Design/methodology/approach

The most probable number method, electrochemical impedance spectroscopy (EIS) measurements, scanning electron microscopy (SEM), three-dimensional (3D) photos and epifluorescent microscopy were used in this study.

Findings

The results showed that the minimum inhibitory concentrations and minimum bactericidal concentrations of them to sessile SRB were greatly more than planktonic SRB. The EIS of the two biocides indicated that the biofilm exposed to higher concentrations of biocide were much more compact and flat, which perfectly coincided with the SEM, 3D photos and the epifluorescent microscopies.

Originality/value

In this paper, it, thus, appears that these methods evaluating biocide performance on the SRB biofilm were really effective by comparing the performance of bis-quaternary ammonium salt (BAQS) and tetrakis hydroxymethyl phosphonium sulfate.

Abstract

Purpose

In the vibration reduction field, constrained stand-off layer damping cylindrical shell plays an important role. However, due to the lack of accurate analysis of its damping characteristics, this hinders its further research and application. Therefore, the purpose of this paper is concerned with an accurate solution for the vibration-damping characteristics of a constrained stand-off-layer damping cylindrical shell (CSDCS) under various classical boundary conditions and conducts a further analysis.

Design/methodology/approach

Based on the Rayleigh–Ritz method and the Hamilton principle, a dynamic model of CSDCS is established. Then the loss factor and the frequency of CSDCS are obtained. The correctness and convergence behavior of the present model are verified by comparing the calculation results with the literature. By using for various classical boundary conditions without any special modifications in the solution procedure, the characteristics of CSDCS with S-S, C-C, C-S, C-F and S-F boundaries are discussed.

Findings

The Rayleigh–Ritz method is effective in handling the problem of CSDCS with different boundaries and an accurate solution is obtained. The boundary conditions have an important influence on the vibration and damping behavior of the CSDCS.

Originality/value

Based on the Rayleigh–Ritz method and Hamilton principle, a dynamic model of CSDCS is established for the first time, and then the loss factor and frequency of CSDCS are obtained. In addition, the effectiveness of adding the stand-off layer between the base shell and the viscoelastic layer is confirmed by discussing the characteristics of CSDCS with S-S, C-C, C-S, C-F and S-F boundaries.
