The OAIS model has gained widespread acceptance as the fundamental design reference model for an archival system by the digital library community. One of its core entities is Preservation Planning, for which central functional entities are given yet without every detail breaking down into activities requirements. The Planets Preservation Planning approach addresses this by providing a way to ma...

In organizations, information systems produce increasing amounts of digital information that needs to be preserved. Simultaneously, human intervention in preservation activities needs to be minimized, due to scarce resources available for preservation. Thus, digital preservation services need to be integrated with other organizational information systems as seamlessly as possible, and preservat...

This study models a joint pricing, inventory, and preservation decision-making problem for deteriorating items subject to stochastic demand and promotional effort. The generalized price-dependent stochastic demand, time proportional deterioration, and partial backlogging rates are used to model the inventory system. The objective is to find the optimal pricing, replenishment, and preservation t...

In spite of the technologies developed during the last decade, the level of food loss is still high and is reported in many countries. According to the United Nations, more than 30 per cent of the mortality rate world-wide is caused by alimentary diseases. The desire of most countries to make food safer for consumption requires better food preservation and production techniques. In this regard,...

Many food products are perishable by nature and require protection from spoilage during their preparation, storage and distribution to give them desired shelf-life. Because food products are now often sold in areas of the world far distant from their production sites, the need for extended safe shelf-life for these products has also expanded. Currently, there is a strong debate about the safety...

Increasingly, content owners are operating repositories with large, heterogeneous collections. The responsibility to provide access to these collections on the long term requires preservation processes such as planning, monitoring, and actual preservation operations such as migration and quality assurance, which have to be managed and integrated with the repositories. This article presents a su...

The goal of digital preservation is to ensure long-term access to digitally stored information. In this paper, we present a survey of techniques used in digital preservation. We also introduce representative digital preservation projects and case studies that provide insight into the advantages and disadvantages of different preservation strategies. Finally, the pros and cons of current strateg...

We introduce the digital preservation problem and explain the importance of metadata for the preservation of the digital information, especially to the cultural content. We emphasize that the digital information will only be available if the necessary metadata are appropriately designed and specified. We also present the Reference Model for an “Open Archival Information System” (OAIS), which is...

Better understanding of the mechanisms of ischemia-reperfusion injury, improvement in the technique of lung preservation, and the recent introduction of a new preservation solution specifically developed for the lungs have helped to reduce the incidence of primary graft dysfunction after lung transplantation. Currently, the limitation in extending the ischemic time is more often related to the ...
