Library Collections

Purpose – The purpose of this article is to study how public libraries argue for the inclusion of non-traditional library collections and to identify public library objectives related to these collections. Design/methodology/approach – The data was collected through a Web survey which was sent to public library managers in all Swedish municipalities. Data were analyzed using a model in which public library practices are divided into three categories relating to the public library’s goals, activities and tools. Findings – Three different main arguments are used to support the introduction of non-traditional collections: as a contribution to public library goals or activities to attract non-users and as the result of external requests or needs. Through analysis of the survey results, the public library’s common goal, a socially sustainable society, was identified. Other library goals identified were an environmentally sustainable society and an improved library. Practical implications – The results may inspire practitioners to reflect upon how non-traditional collections are related to library goals and activities and what consequences their inclusion may have for the library. For example, if non-traditional collections are used only to attract new users, there is a risk of creating expectations that the library cannot live up to. Originality/value – Today, focus is placed on the conditions for public libraries in the digital world. It is easy to overlook the importance of non-traditional library collections, and the role they fulfill. This article draws attention to these collections and their possible consequences for public libraries.

AbstractGiven their ubiquity in modern society, the development of biodegradable and renewably sourced plastics is essential for the creation of an environmentally sustainable society. One of the drawbacks for currently available biodegradable plastics such as poly(l-lactic acid) (PLLA) and polyhydroxyalkanoates (PHAs) is that it is difficult to simultaneously achieve mechanical flexibility and certain crystallization behavior in these materials, which limits their use as replacements for established petroleum-based plastics such as isotactic polypropylene (iPP). Here, we report the synthesis and characterization of a new biodegradable plastic, poly(3-hydroxy-2-methylbutyrate) [P(3H2MB)], which is a member of the bacterial PHA family whose members include an α-methylated monomer unit. Biosynthesis of P(3H2MB) was achieved using recombinant Escherichiacoli expressing an engineered pathway. Biosynthesized P(3H2MB) exhibited the highest melting temperature (197 °C) among the biosynthesized PHAs and improved thermal resistance. It also exhibited improved crystallization behavior and mechanical flexibility nearly equal to those of iPP. The primary nucleation rate of P(3H2MB) was faster than that of P(3HB), and the spherulite morphology of P(3H2MB) was much finer than that of P(3HB). This crystal morphology may result in more rapid crystallization behavior, increased transparency, and enhanced mechanical properties. The superior physical properties of P(3H2MB) have the potential to open new avenues for the production of high-performance biodegradable plastics for replacing petroleum-based bulk commodity plastics.

Poor management of dump-sites creates significant risks to environment and human health. Thus, sanitary landfills are required to be more effective to minimize the impacts of waste disposal. This research assesses the environmental economic evaluation focused on the economically efficiency of Malaysian sanitary landfills. Two landfills were selected based on their different operation. Landfill A incurred RM 128 million (USD 41.8 million) as the total cost within 20 operational period. Thus, it is estimated that the cost may be covered within 15 operational years. On the other hand, the total costs for Landfill B are estimated at RM 198 million (USD 64.8 million) with RM 245 million (USD 80.2 million) are expected to be obtained as profit within eight operational years. Landfill B has high initial costs of design and construction. However, the costs are covered within the first five years. This is because Landfill B introduces a new green technology namely landfill-gas power generator. This indicates that, Landfill B has stronger market competition ability as compared to Landfill A. It can be concluded that the implementation of green technology namely landfill gas harvesting system has higher impact to improve the economic value of a landfill thus making it more economical and environmentally sustainable.

Role Of Information

If we want to convert our rural population into knowledge driven, progressive, self sufficient, self reliant, sustainable society, the role of Information and Communication Technologies (ICT’s) cannot be ignored. Timely availability information is considered as most important factor in Indian agriculture. At present ICT is the technology of this millennium. Transferring the developed technology to all end users is time-consuming and tiresome task and is often not completed due to paucity of resources and lack of manpower. In India, agriculture and rural development has gained significantly from ICT due to its widespread extension and adoption. In this era of internet, ICT is committed to provide real, timely accurate authentic information to the farmers and rural peoples.
