Short stemmed hip endoprostheses represent a relevant alternative to standard sized total hip stems. Especially in terms of bone stock preservation and minimal invasiveness the reduced length of such implants is beneficial. However, the smaller implant size is linked to a reduced surface geometry and thereby bone-implant-interface to provide implant stability. In order to evaluate the interfaci...

The study was conducted to determine the effect of 7-dehydrocholesterol loaded cyclodextrin (7-DHCLC) and cholesterol-loaded cyclodextrin (CLC) on changes of bull sperm motility during short term storage (+4°C). Collected ejaculates were pooled and divided into 7 groups, as following one control (C); three 7-DHCLC and the other three CLC concentrations. Diluted semen samples were transferred an...

This short paper attempts to highlight some challenges to be tackled by DP research in the next years, taking as a starting point the perspective of preservation planning. These challenges are in short: (1) Scalability (up and down) requiring (2) measurement of relevant decision factors, in turn requiring (3) benchmarking and ground truth. (4) Quality-aware emulation. (5) Move from the current ...

Many women of childbearing age are diagnosed with cancer in the United States each year. Improved survival rates can give many time to still have their own families if they choose. Although cancer treatments can dramatically increase survivorship, they also can negatively affect future fertility. Women newly diagnosed with cancer may not be aware of the possible damage to their future fertility...

Small businesses (small office/home office, SOHO) have tremendous amounts of digital information. At the same time, they have little to no expertise on how to manage it, not to mention caring for their long-term preservation, as even simple back-up strategies pose already drastic challenges. This demo presents the Hoppla archiving system to provide digital preservation solutions specifically fo...

This research lays the foundations for a new object-centric digital preservation paradigm based in computational intelligence, where the digital objects manage their own preservation and budget, powered by a social network as an environment that enables their behavior under the policy that “preservation is to share”. The mission of these objects is their long-term preservation, which entails be...

Selection and metadata issues which surround the preservation of digital information are discussed, in particular, the assignment of “collection levels” to Web materials to ensure preservation, and some Preservation Metadata Element Sets (PMES) which have been identified as informed by the Open Archival Information System (OAIS) Reference Model. A metadata framework that can support a broad ran...

We present and evaluate a novel constraintbased model transformation approach that implements a preservation-centric view. The proposed framework comprises formal preservation constraints that can be used to specify the preservation of invariants that are possibly implemented differently in the source and target model. These invariants are enclosed in concepts, which at the same time serve as g...
