International standards for global information.
Providing new insights into the role of librarianship in an age of socioeconomic, environmental, and political transformation, Global Librarianship illustrates how globally networked environments promote and increase the sharing and dissemination of ideas, information, and solutions to obstacles affecting libraries. This reference showcases methods to tailor and build collections and technologies that continually support worldwide scholarly and business communities through the utilization of digital tools and electronic media. It Illustrates breakthroughs in the organization, management, and dissemination of information to facilitate easy access to libraries anywhere in the world.
Bibliographic networking and law libraries in Nigeria
th century to the present. Some of the benefits of networking such as increase in production, cost effectiveness and production of high quality products and services are discussed extensively in the paper. Two major challenges towards networking of bibliographic resources of law libraries in Nigeria – absence of automated systems and lack of training for law librarians are discussed. The paper positions that the way forward towards networking will include automating systems and services, creating network centers and training for librarians.
Ceramic microwave antennas for mobile applications
Due to their medium to high permittivity values, ceramic microwave materials are attractive as building blocks for miniaturised antenna solutions. Further advantages are low dielectric losses and an excellent temperature stability of standard ceramic materials. Yet, the permittivity of the ceramic material also has a strong influence on the radiation efficiency and bandwidth of the antenna. This implies that in the design process a suitable compromise has to be found between the degree of miniaturisation on the one hand and the antenna efficiency and bandwidth on the other. We describe two approaches towards efficient miniaturised ceramic microwave antennas: the dielectric resonator antenna (DRA) with partial metallisation and the shorting post patch antenna. We focus on design steps taken to ensure both a high degree of miniaturisation and high values of the radiation efficiency, the choice of the ceramic material and the experimental performance of the antennas.
