This investigation deals with the use of orange peel (OP) waste as adsorbent for removal of nitrate (NO3) from simulated wastewater. Orange peel prepared in two conditions dried at 60C° (OPD) and burning at 500 °C (OPB). The effect of pH: 2-10, contact time: 30- 180 min, sorbent weight: 0.5- 3.0 g were considered. The optimal pH value for NO3 adsorption was found to be 2.0 for both adsorbents. The equilibrium data were analyzed using Langmuir and Freundlich isotherm models. Freundlich model was found to fit the equilibrium data very well with high-correlation coefficient (R2). The adsorption kinetics was found to follow pseudo-second-order rate kinetic model, with a good correlation (R2 > 0.95 and 0.94) for the orange peel adsorbent at 500 °C (OPB) and at 60 °C (OPD), respectively. The results showed that the orange peel was found to be an attractive low cost adsorbent for the treatment of wastewater.

Pomegranate peels were chosen for the ability to adsorption of lead ions from the simulated wastewater. It has been tested under various experimental parameters such as pH, contact time, weight of sorbent, and concentration of metal and effect of temperature. The outcomes indicated that adsorption of Pb (II) ions on the pomegranate peels can be appropriated with the Langmuir adsorption model and pseudo-second-order kinetic model. Result showed that the Pomegranate peel was found to be low-cost adsorbent for the removal of contaminates. A good efficiency to remove toxic metal ions was achieved by usage of such by- product.

This paper reports on the user evaluation to examine participants' acceptance of an e-workspace that has been developed to support the process of teaching, learning and researching manuscripts in the Malay manuscript community. This evaluation is conducted to answer the following research question: a) What is the perceived usefulness of the e-workspace in supporting transliteration work and collaboration from the Malay manuscript community? b) What are the usability issues highlighted regarding the Malay manuscript e-workspace? The evaluation is carried out based on five usability dimensions, namely, efficiency, effectiveness, engagement, error tolerance and ease of learning. A single case study has been employed in this evaluation which included lecturers, students, and researchers from the Academy of Malay Studies, University of Malaya as participants. These participants are directly involved in teaching, learning and researching Malay manuscripts. The user evaluation is carried out in two phases. The first phase involves a task-based approach where participants are given several tasks to perform while using the e-workspace. The second phase is a focus group discussion to elicit the participants' feedback on the perceived usefulness of the e-workspace after they have completed the given tasks. System evaluation of the Malay Manuscript e-workspace in serving the manuscript community has been reflected by the positive feedback from the 19 participants. The findings signify a positive reaction from participants towards the e-workspace. The e-workspace in general has been perceived as useful to support teaching, learning and researching manuscripts by providing a collaborative platform to conduct transliteration work electronically.

This paper presents the relative percentile of diffusion (RPDiF) and compares it with the results of the following indicators: synchronous diffusion factor (DiF), synchronous relative diffusion factor (RDiF), and the five years impact factor (5IF) scores -- to assess the influence of journals. The approach involves collection, analyses and comparison of bibliometric data for42 Malaysian journals that have garnered citations in the Web of Science (WoS) during 2006 to 2010.Findings show that it is important to read the RDiF with the RPDiF because RPDiF shows that journals with high RDiF and low RPDiF do not possess strong quality profile like those with both high RDiF and RPDiF. The paper concludes that a journal can be said to demonstrate high quality impact and influence if it achieves a high DiF, RPDiF and 5IF. This study contributes in providing an additional quality indicator to evaluate journals not indexed by mainstream citation databases. [ABSTRACT FROM AUTHOR]

This paper explores visually impaired persons' (VIPs) sense of belonging in a university library context. It focuses on their perceptions of and experiences with study carrels located in the university library. Data were collected during interviews and focus group discussions. Participants consisted of five female and thirteen male students between the ages of 20 and 37 years. Participants considered their carrels as second homes where they felt safe, comfortable, and accepted. The carrels gave them a sense of belonging. The carrels also served as social places where the VIPs could interact with peers, volunteer readers, and other sighted students. The VIPs viewed their carrels as quiet havens where they could study and learn. They felt they belonged to the library community and were proud to be accepted as students at the university. The findings may increase library managements' awareness of the need to include these types of spaces in future design. [ABSTRACT FROM AUTHOR]

The problem with the identification of Malaysian scholarly journals lies in the lack of a current and complete listing of journals published in Malaysia. As a result, librarians are deprived of a tool that can be used for journal selection and identification of gaps in their serials collection. This study describes the audit carried out on scholarly journals, with the objectives (a) to trace and characterized scholarly journal titles published in Malaysia, and (b) to determine their visibility in international and national indexing databases. A total of 464 titles were traced and their yearly trends, publisher and publishing characteristics, bibliometrics and indexation in national, international and subject-based indexes were described.

Explores the use of an assessment instrument based on a model named library information systems security assessment model (LISSAM) to assess the ISS status in special and public libraries in Malaysia. The study aims to determine the implementation status of technological and organizational components of the LISSAM model. An implementation index as well as a scoring tool is presented to assess the IS safeguarding measures in a library. Data used was based on questionnaires distributed to a total of 50 individuals who are responsible for the information systems (IS) or IT in the special and public libraries in Malaysia. Findings revealed that over 95% of libraries have high level of technological implementation but 54% were fair poorly on organizational measures, especially on lack of security procedures, administrative tools and awareness creation activities.

The article proposes a model for developing a collection security management assessment instrument for university libraries. The model is made up of five elements that include collection security governance, operations and processes, people issues, physical and technical issues and the security culture in libraries. The model was tested in four university libraries in Nigeria and was shown to be reliable based on all five elements, with reliability values ranging from 0.7 to 0.9.

It is difficult to determine the influence and impact of journals which are not covered by the ISI databases and Journal Citation Report. However, with the availability of databases such as MyAIS (Malaysian Abstracting and Indexing System), which offers sufficient information to support bibliometric analysis as well as being indexed by Google Scholar which provides citation information, it has become possible to obtain productivity, citation and impact information for non-ISI indexed journals. The bibliometric tool Harzing's Publish and Perish was used to collate citation information from Google scholar. The study examines article productivity, the citations obtained by articles and calculates the impact factor of Medical Journal of Malaysia (MJM) published between 2004 and 2008. MJM is the oldest medical journal in Malaysia and the unit of analysis is 580 articles. The results indicate that once a journal is covered by MyAIS it becomes visible and accessible on the Web because Google Scholarindexes MyAIS. The results show that contributors to MJM were mainly Malaysian (91%) and the number of Malaysian-Foreign collaborated papers were very small (28 articles, 4.8%). However, citation information from Google scholar indicates that out of the 580 articles, 76.8% (446) have been cited over the 5-year period. The citations were received from both mainstrean foreign as well as Malaysian journals and the top three citors were from China, Malaysia and the United States. In general more citations were received from East Asian countries, Europe, and Southeast Asia. The 2-yearly impact factor calculated for MJM is 0.378 in 2009, 0.367 in 2008, 0.616 in 2007 and 0.456 in 2006. The 5-year impact factor is calculated as 0.577. The results show that although MJM is a Malaysian journal and not ISI indexed its contents have some international significance based on the citations and impact score it receives, indicating the importance of being visible especially in Google scholar.

Details of statements under the dimensions highlight the issues that are unique and not covered by previous studies in library anxiety. [ABSTRACT FROM AUTHOR]

It is a common fallacy to assume that undergraduates are skilled in finding and evaluating resources for their various learning needs. Information professionals need to find out strategies and courses of action undertaken by undergraduate students in order to perhaps improve information literacy skills or user education programmes. This qualitative study uses the diary, emails interaction and in depth face to face interview approach involving 14 final year Computer Science and Information Technology undergraduates whom shared their information search and use process. The objectives of this study are to find out the followings: (a) the decision on deciding research topics by final year students; (b) the sources and channels of information they use and prefer; (c) the utility of libraries and librarians; (d) the use of the Internet; (e) the search strategies adopted; (f) their thoughts on intellectual property and ethical issues. Among the main information sources used were the Internet, books and previous final year project reports. They also seem to rely a lot on their friends and lecturers as their source of information. Very few used journal articles, seminar papers or other sources. An understanding of their information seeking behaviour patterns is the focus of this paper. Informants' thoughts and feeling on the library services and the ethical use of information will be shared. [ABSTRACT FROM AUTHOR]

The study uses research-based resources listed in two published bibliographies on "Women in development in Malaysia" produced between the pre 1970 years and 2004 to describe the growth and pattern of women's studies in Malaysia. A total 4037 resources formed the basis of the study. Bibliometric measure are used to indicate the annual growth of literature over the periods, the preferred publication channels used by the authors, the subject areas of research interests, the active authors and the inference of collaboration based on co-authored works. The results indicate a growth in women's studies especially between 1990 and 2004 totaling 3346 publications, averaging about 258 titles per year compared to the average of 36 titles for the pre 1970 and 1989 years. There were heavier activities in economic studies, social-cultural studies, women's health and welfare and women in literature. The main types of publication produced are undergraduate academic research reports, master dissertations and doctoral theses. Conference presentations and journal articles are equally popular. Most authors in this field are one time contributors and only 18 authors produced 10 or more publications each. The majority of authors work alone indicating a low collaboration rate. The study proposes a collaborative e-bibliographic initiative to serve and sustain researchers' information needs in this field. [ABSTRACT FROM AUTHOR]

The paper attempted to provide a "picture" of Malaysian US research and publications. The study aimed to show (a) the total number and spread of publications produced by Malaysian authors; (b) the active authors; (c) the authorship pattern; (d) the affiliation status of the authors; (e) the main channels used to publish; and (f) the subject covered by the published works. The study confined its scope to the publications produced between 1965 and 2005 by Malaysian authors published in Malaysia as well as abroad. Bibliometric techniques and regression analysis were employed as the measuring instrument. The data was collected from seven online databases and seven well established library OPACs, which are expected to hold earlier and current US publications. A bibliometric toolbox was used to feed in text files which provided brief summaries of ranked results, a bibliograph and minimal Bradford zonal analysis. The subject categorization used by Gorman and Corbit's Model of core competencies for US was used to categorized entries by subjects. The results indicated that (a) Malaysian US authors preferred to publish in journals (511, 48.9%) and conference papers (474, 45.4%); (b) the publication distribution fluctuated over the 41 year period but the moving average depicted a steady incremental trend; (c) a total of 506 authors contributed to 1,045 publications and 309 are one-time authors' (d) the active authors in LIS are affiliated to 131 institutions and the productive institutions were the national Library of Malaysia, University of Malaya library and the academics at the MUS Programme, University of Malaya.; (e) publication productivity was related to institutional active involvement in US journal publishing; and (/`) the main subject areas actively researched upon were collection development and management, information centres and services, and ICT applications US.

This is an exploratory attempt to use a modified version of SERVPERF to assess user's satisfaction with the services provided by an ISO9000:2000 certified library at a private university in Malaysia where measuring performance would be an integral part to continuously improve quality of services. The services being measured are grouped as frontline, core and peripheral where staff and facilities interact with users directly and where user's opinions and expectations could be extracted. The clients are undergraduates and postgraduates who use these services and facilities. The results identify services deem important to users of the library as well as the problem areas which need improvements. A total of 274 students comprising 250 undergraduates and 24 postgraduates form the sample. The respondents' ratings range on average between 3.13 and 4.36 on a 5-point scale, implying that the library is performing at an above average level. From 59 service attributes, 2 are perceived as excellent, 20 attributes are considered good, 31 are average and 4 services are rated as poor. A total of 16 services are rated below 50%, which form the priority list of services given priority in the library's proposed action plan. The good and excellent services would continue to be monitored to maintain their performance. [ABSTRACT FROM AUTHOR]

This exploratory study focuses on identifying the usage pattern of e-books especially on how, when, where and why undergraduates at the Faculty of Computer Science and Information Technology (FCSIT), University of Malaya (UM), Kuala Lumpur use or do not use the e-books service provided by the University of Malaya library. A total of 206 (82%) useable questionnaires form the basis of analysis. The results indicate even though the students are heavy users of the Internet, rate themselves as skilled in Internet use and have positive attitude towards the e-book service, the level of e-book use is still low (39%). The students become aware of the e-book service mainly while visiting the University of Malaya Library Website, or are referred to it by their lecturers, friends or the librarians. About 70% rate positively on the e-book service. Those who are users of e-books find e-books easy to use and their usages are mainly for writing assignment or project work Most respondents prefer to use e-versions of textbooks and reference sources. Generally, both users and non-users of e-books prefer to use the printed version of textbooks especially if the text is continuously used. There are significant difference between the frequency of e-book use and gender; between past usage of e-book and preference for electronic textbooks and reference books. The possible factors which may be related to e-book use are categorized into 4 groups and presented in a model, which comprises the ICT competencies of the students, their cognitive makeup, the degree of user access to the e-books and the functional or use factors.

Presents a study that determined the types of access given to online databases by several private colleges and universities in Malaysia. Background of the study; Research methodology; Results of the provision of online databases, computer facilities and promotion of usage of the online databases; Conclusion of the study.

Focuses on a study that revealed the availability status of quality journals in the field of computer science held in the libraries of selected universities in Malaysia. Determination of the status of availability of ranked journal titles listed in the Journal Citation Report; Assessment of the strength and weaknesses of journal collection in the field of computer science; Analysis of the cost involved in overlapping journal subscription; Suggestions to lessen the impact of rising cost of journal subscriptions.

This study describes the availability of quality journals held at the University of Malaya Library (UML) in the field of computer science and compares this to the availability of journal collections in four other university libraries: Science University of Malaysia (USM), University of Technology Malaysia (UTM), National University of Malaysia (UKM), and University Putra Malaysia (UPM). All the universities included in the study have been established for more than fifteen years and offer degree programmes in computer science. Quality journals refer to the 301 titles with impact-factor scores listed in the Journal Citation Report 1999 (JCR) in the field of computer science. The study also investigates the degree of journal overlap among the five university libraries. The UML was taken as a case study to show how overlap titles are ascertained and costs calculated. The results indicate that (a) UML holdings of quality journal titles is poor and that a similar pattern is indicated in the other university libraries (34.22% by UML, 40% by UTM, 16% by UKM, 31% by USM, and 23% by UKM); (b) for the five libraries, out of the 301 titles, 115 (38.2%) overlap, 96 titles (32.23%) are singly-held titles, and 84 titles are not subscribed to; (c) the percentage of overlap is related to the size of title availability; (d) the cost of journal title overlap for UML is estimated to be about U.S.$79,650.40, and the cost of the titles not subscribed to is U.S.$41,440.32. It is proposed that cooperative subscription ventures would help reduce costs and release monies to cover the other quality titles not subscribed to by any of the libraries. [ABSTRACT FROM AUTHOR]
