Prestressed Concrete Cylinder Pipe

This paper presents a case study of an existing wastewater rising main (WWRM) in which an extreme transient event produced by simultaneous power failure of the pumps caused the rupture of a 1.2 m (48 in) prestressed concrete cylinder pipe (PCCP), causing an important leakage of sewage. The event and the methodology followed in order to validate the diagnostics of the failure are described. The detail study included in situ observation of the system, experimental investigation in a setup, hydraulic analysis, as well as details of the structural strength of the WWRM. After the extensive investigation and several simulations of fluid transients for different scenarios and flow conditions, it was found that stationary small gas pockets accumulated at high points of the WWRM were identified as the principal contributory factor of the failure. This case study serves as clear warning of the consequences of operating a WWRM with gas pockets at its high points.

Gender Specific

This paper investigates gender differences in asset ownership. Specifically, the present case study explores whether a gender-specific composition in asset ownership between heads of households and spouses can be detected among low-income, urban households in Bangkok, Thailand. To examine this issue empirically we use a sample of 134 couples from a 2002 survey. Data collected were at the level of the individual respondent on accumulated physical and financial assets and both husband and wife were interviewed separately. The findings suggest that asset composition varies by gender, indicating that further investigation is warranted on this topic. Tobit and Probit tests are used to examine the factors that may affect this gendered pattern.

Structured Questionnaire

This study was carried out to determine how availability and accessibility could bring about sustainable development in perceived academic performance of polytechnics’ students using Ibadan Polytechnic as a case study. Survey design was used with structured questionnaire and observation as instruments for data collection. The questionnaire was administered with the aid of a research assistant. From the findings, it was revealed that textbooks and dictionaries were readily available in the library while electronic books and journals were not accessible. The study also revealed lack of enough electronic resources, lack of enough computers to access Online Public Access Catalog (OPAC) and power failure as some of the challenges to availability and accessibility of library resources. Some recommendations were made based on the findings.

Purpose – The purpose of this paper is to present the ways in which online cataloguing is used to provide twenty-first century library and information services to a university community in a developing country, together with the challenges and prospects of such an application. The paper aims to examine the use of the internet to catalogue and classify library materials in the University of Ilorin Library. It looks at the use of the Library of Congress Catalogue in copy cataloguing. This paper also discusses the use of Koha, a free library integrated software to classify and catalogue library resources in the University of Ilorin Library. Design/methodology/approach – The methods used are participant observation, interviews with the senior librarians in the library and visits to another library that uses Koha software. Periodical and online articles were also used to gather information to support this study. Findings – The major problem is incessant power failure and the library is planning to get a heavy and very powerful inverter and generator that can stop the disruption of work resulting from the intermittent power supply. Another setback in using Koha is that the cataloguing is being done online unlike Biblofile which is done offline. Research limitations/implications – The researchers visited only one university library in the course of the research. This is due to financial constraints. Practical implications – Information communication technology training must be taken seriously for librarians who want to remain relevant in this age of information technology. Originality/value – This study about Koha software usage is the first of its kind to be carried out in the University of Ilorin Library and will be useful to other university libraries.
