    Fracture toughness and crazing behaviour of virgin and filler added polystyrene films
    (University of Peradeniya, 2005) Kuhanesan, Sinnathamby
    Brittle fracture commonly observed in many glassy polymers under tension is due to the formation and breakdown of crazes. Fillers exist in a variety of systems such as organic, biological and polymeric materials. In polymer systems, nanoscale fillers not only reduce the cost of the material but also improve mechanical properties, such as hardness and tear resistance, The broad aim of this study was to investigate the fracture behavior of virgin and filler added polystyrene thin films by the trouser leg tearing test. Critical strain energy release rate (G,) can be regarded as a material property, often equated with toughness. The thin films, required for the tearing test, were prepared by two different methods. In the first method, a glass slide was dipped and drawn with different speeds using a motor driven lifter through a polystyrene solution. The other method was spin casting, in which the prepared solution was placed on a clean glass slide and spun with different speeds using a photo resist spinner. Toluene was used as a solvent. The virgin polymer films were prepared with a moderate solution of 14 wt-%, of polystyrene in toluene. A solution of 14 wt-%, of polystyrene and filler in toluene was used for filler added films preparation. The composition of the filler - added films was varied from 0 to 5 wt-% of fillers with respect to polystyrene content. In this study, carbon black (0.05 um), alumina (0.075 pm) and fumed silica (255 m’/g) fillers were used. The slides were dried in a vacuum desiccator oven at 80°C for 12 hours for complete evaporation of toluene from the films. The samples used in this study were of rectangular shape (40 mm x 15 mm). They were stripped off from the substrate onto the surface of a water bath. The thickness of the films was measured using a Michelson interferometer and a locally made thickness measuring instrument. A cut of 10 mm was made along the center line of the sample and two free ends were separated at constant rates using a mechanical testing machine. Tearing was done in two different directions, one parallel and the other perpendicular to the film drawn direction. The study revealed that the G, values of virgin polystyrene were strongly dependent on the film drawing speed. When the films were torn parallel to the film drawn direction, there was a significant increase in G,, with increasing film drawn speed from 0.5 cm min’ to 2.5 cm min” and there after almost a plateau, was observed. On the other hand, value of G, for all the samples torn perpendicular to the film drawn direction, there was a clear decrease in G, with increasing film drawn speeds. The value of G, for the films which were prepared by spin casting, torn in both perpendicular directions is 0.24 kJ m”. This is almost constant for all the films which were prepared with different spin speeds and this value is comparable with the G, value corresponding to the above mentioned plateau. The reason for such a variation in the above films could be the high degree of orientation of the polymer chains in the film drawing direction due to the very slow drawing speed. When the drawing speed was increased the degree of polymer chain orientation decreases and becomes randomly oriented. The study also revealed that a significant decrease in Ge with the increasing filler wt-%, in the films which contained alumina and carbon black fillers, prepared by both methods. On the other hand, the films which contained fumed silica and torn in the film drawn direction showed a decrease in G, value with increasing filler wt-%. In contrast, an increase in G was observed, when the fumed silica added films were torn perpendicular to the film drawn direction. The spin cast films also showed an increase in G, with fumed silica filler wt-%. The most likely reason why such a decrease in G, was observed in alumina and carbon black filler added films is the propagation of the fracture mostly along the filler particles. It can be speculated that there may not be any extra - ordinary interaction between the polymer and fillers. Unlike other fillers, fumed silica has a chain - like particle morphology. The decrease in G, value in the fumed silica added films which were torn parallel to the film drawn direction may be due to the fumed silica chains and polystyrene chains aligning parallel to the film preparation direction. Tearing parallel to the direction of preferential alignment requires the rupture of fewer bonds as orientation increases and hence, less stress is needed to tear the film in this direction. The polymer chains and fumed silica chains, in the spin cast films, were randomly oriented. These fumed silica chains give additional strength to the polystyrene. Optical microscopic study shows the formation of craze areas ahead of the crack tip in a torn virgin polymer film. In addition to this, micro shear bands were also observed ahead of the craze region and on the sides of the fracture surfaces. The craze area ahead of the crack tip in torn polymer films showed birefringence indicating that there exists a certain degree of orientation of polymer chains in these areas. It was also observed that less amount of crazes in the alumina filler added films. Though the fumed silica added films which were torn perpendicular to the film drawn direction showed higher G, values, the amount of craze in the films was less compared to the virgin film. On the other hand, the films which contained carbon black fillers showed very low G, value and no crazes were observed. Unlike cracks, crazes are load bearing since their surfaces are bridged by many fine fibrils. Crazes are the major toughing mechanism in the polystyrene amorphous polymer.

A total number of 65 authors have produced 77 Tamil publications which have been taken for this analysis. Out of 91 publications, 15% are edited publications. Most of the publications 40% is published in Colombo and the Traditional Tamil cities - Jaffna and Batticalo contributed 1 1% and 9% to the publishing field respectively. Most of the Muslim origin publications were published in the Eastern Provincial Region amounting to 15% and the Upcountry area contributed to the Tamil Publication with 16%. 15% of the publications are brought about by the authors. Only 08% publications were published by departmental or government funds. Two private publishers published 04% of the publications each. Out of 91 publications printed in year 2005, 6 % were published in length size of 21 cm and 29% in 22 cm. There are 14 editors in 2005 and all editors edited only one publication each.40 of publication in Tamil literature 18 % in religious and 10 in social science.

    Assessing library collection: a case study at University of Peradeniya
    (University Librarians' Association of Sri Lanka, 2009) Gunasekera, Chamani
    In Feb, 2008 management of the Main Library, University of Peradeniya (UP) decided to carry out a collection assessment project to gain information on its collection at subject level. Particularly in a university library, collection assessment is necessary to evaluate whether the collection is able to support the institution's curriculums and fulfill the teaching, learning and research needs of the staff and students of the university. The results of the assessment could be used to compile a collection development policy in the library and identify the strengths and weaknesses of the collection. In this study physical stock counting method which comes under the collection –centered approach was chosen to evaluate the monograph portion according to subjects. The paper describes the process, methods used and results obtained from the assessment. Finally it briefs some suggestions to be used in future collection assessment projects to gain comprehensive information on the collection.

    A comparison of the requirements of university library quality assurance system with internationally recognised ISO 9001:2000 and ISO 9001:2008 quality management systems
    (University Librarians' Association of Sri Lanka, 2011) Dissanayake, Harshani N.K.
    Providing a quality service has become a must in the library and information science sector today. The readers expect an effective and efficient library service from the library staff. Therefore providing a customer oriented service has become a challenge to the librarians and information professionals. The University Grants Commission has initiated a Quality Assurance System for all the faculties and the academic libraries of the Universities under the World Bank project, Improving Relevance and Quality of Undergraduate Education (IRQUE). The quality management systems (QMS) ISO 9001:2000 and ISO 9001:2008 are internationally recognized Quality Management Systems. They have been successfully implemented in some Sri Lankan libraries to provide an effective service to the library users. A comparison of the requirements of the University Library Quality Assurance System and the two international standards is carried out in this study.

    User Perspectives on Digital Reference Services (DRS): A Study of State University Libraries in Sri Lanka
    (South Eastern University of Sri Lanka, 2024-02) Bandara, B.E.S.; Hindagolla, B.M.M.C.B.
    Purpose: The provision of human intermediated service to users over a digital network is identified as DRS and an essential service for novel users who are much more comfortable with new technologies. It is a question whether patrons are aware of DRS available for them. This study demonstrates the users’ awareness level on DRS, benefits and user suggestions to improve DRS activities in academic libraries in Sri Lanka. Identifying the available ICT facilities for DRS, level of satisfaction on DRS, the benefit obtained through DRS and identifying suggestions to improve DRS in Sri Lanka are the objectives of the study. Methodology: Undergraduates of the state universities in Sri Lanka were the population of the study where 240 number of responds selected using the convenience sampling technique via an online questionnaire survey. Poor response of the users was a major limitation. Findings: Results revealed that many of the users are aware about computers, servers, scanners, and printers along with Wi-Fi facilities are available at their libraries for DRS. Only 22% of the respondents aware about library mobile apps and 33% about online indexes used for DRS. 36% of users previously used DRS. 25% stated that DRS need more improve where 23% are satisfied with what they obtained as DRS. Users were not happy about video conferencing, reference bots and web reference among the DRS provided. Personalized Service, convenience, time factor, no time and location barriers and faster service identified as highest ranked benefits by the users. Improving network facilities, online resources with remote access facilities, funding for establishing well equipped libraries with proper infrastructure, providing awareness and adequate training were the suggestions for improving DRS by the library users. This is denoted that whatever the back-end processes were there when implementing DRS in libraries, what users feel is the interface and the services through the platform. Implications: Librarians must focus their attention on developing user friendly interfaces to cope with end users in real time and in a sustainable manner. With the support of the donors and collaboration academic libraries may enhance their digital collections to have rich knowledge base to provide better DRS in future.
