Book Description
Bidirectional traffic of macromolecules across the nuclear envelope is an active and essential transport process in all eukaryotic cells. Work on various model systems has led to a tremendous increase in our understanding of nuclear transport in recent years. This volume summarizes our current knowledge of protein and RNA transport into and out of the nucleus. It contains nine up-to-date reviews which cover various aspects of nucleocytoplasmic transport, including the structure and function of the nuclear pore complex, the role of soluble transport factors in protein and RNA transport, and the regulation of protein transport through the nuclear pore.

Book Description
This new report from the National Research Council's Nuclear and Radiation Studies Board (NRSB) and the Transportation Research Board reviews the risks and technical and societal concerns for the transport of spent nuclear fuel and high-level radioactive waste in the United States. Shipments are expected to increase as the U.S. Department of Energy opens a repository for spent fuel and high-level waste at Yucca Mountain, and the commercial nuclear industry considers constructing a facility in Utah for temporary storage of spent fuel from some of its nuclear waste plants. The report concludes that there are no fundamental technical barriers to the safe transport of spent nuclear fuel and high-level radioactive and the radiological risks of transport are well understood and generally low. However, there are a number of challenges that must be addressed before large-quantity shipping programs can be implemented successfully. Among these are managing "social" risks. The report does not provide an examination of the security of shipments against malevolent acts but recommends that such an examination be carried out.

Book Description
The transport requirements of the nuclear industry are unique in many respects. Thi s is not because cargoes are particularly large or hazardous by compari son wi th other industries but because standards of performance required in every aspect of the activity are so much greater than those required for any other industry. Transport of nuclear materials is subject to existing statutory regulations applied not only nationally but internationally. In addition to this, users of transport demand the highest standards of performance for their own purposes particularly in the area of quality assurance. Similar considerations also apply to the transport of non-nuclear materials where the transport link often has to tie in with project management and quality assurance requirements. Safety and security of nuclear materials are of paramount importance but even when these aspects are of a completely acceptable standard public attitudes to the transport activities have to be addressed adequately. The transport system itself consists of many components. The route, the vehicles, the containers, and the individual packages. The performance of each component determines the performance of the total system: all these factors were presented in the 1988 Conference on Transportation for the Nuclear Industry, giving a broad over-view of current practice together with wide ranging consideration of future requirements and developments.

Book Description
In eukaryotic cells, the nuclear genome and its transcriptional apparatus is separated from the site of protein synthesis by the nuclear envelope. Thus, a constant flow of proteins and nucleic acids has to cross the nuclear envelope in both directions. This transport in and out of the nucleus is mediated by nuclear pore complexes (NPCs) and occurs in an energy and signal-dependent manner. Thus, nucleocytoplasmic translocation of macro molecules across the nuclear envelope appears to be a highly specific and regulated process. Viruses that replicate their genome in the cell nucleus are therefore forced to develop efficient ways to deal with the intracellulZlr host cell transport machinery. Historically, investigation of Polyomavirus replication allowed identification ofsequences that mediate nuclear import, which led subsequently to our detailed understanding of the cellular factors that are involved in nuclear import. Transport ofmacromolecules in the opposite direction, however, is less well understood. The investigation of retroviral gene expression in recent years pro vided the first insights into the cellular mechanisms that regulate nuclear export. In particular, the detailed dissection of the function of the human immunodeficiency virus type I (HIV-I) Rev trans-activator protein identified CRMI, as a hona fide nuclear export receptor. CRM I appears to be involved in the nucleocytoplasmic translocation of the vast majority of viral and cellular proteins that have subsequently been found to contain a Rev-type leucine-rich nuclear export signal (NES).

Book Description
Dysfunction of nuclear-cytoplasmic transport systems has been associated with many human diseases. Thus, understanding of how functional this transport system maintains, or through dysfunction fails to maintain remains the core question in cell biology. In eukaryotic cells, the nuclear envelope (NE) separates the genetic transcription in the nucleus from the translational machinery in the cytoplasm. Thousands of nuclear pore complexes (NPCs) embedded on the NE selectively mediate the bidirectional trafficking of macromolecules such as RNAs and proteins between these two cellular compartments. In this book, the authors integrate recent progress on the structure of NPC and the mechanism of nuclear-cytoplasmic transport system in vitro and in vivo.

Book Description
Safe and Secure Transport and Storage of Radioactive Materials reviews best practice and emerging techniques in this area. The transport of radioactive materials is an essential operation in the nuclear industry, without which the generation of nuclear power would not be possible. Radioactive materials also often need to be stored pending use, treatment, or disposal. Given the nature of radioactive materials, it is paramount that transport and storage methods are both safe and secure. A vital guide for managers and general managers in the nuclear power and transport industries, this book covers topics including package design, safety, security, mechanical performance, radiation protection and shielding, thermal performance, uranium ore, fresh fuel, uranium hexafluoride, MOX, plutonium, and more. Uniquely comprehensive and systematic coverage of the packaging, transport, and storage of radioactive materials Section devoted to spent nuclear fuels Expert team of authors and editors
