If not for the Internet Archive’s efforts to store periodic snapshots of the web, many sites would not have any preservation prospects at all. The barrier to entry is too high for everyday web sites, which may have skilled webmasters managing them, but which lack skilled archivists to preserve them. Digital preservation is not easy. One problem is the complexity of preservation models, which ha...

Preserving digital information over the long term becomes increasing important for large number of institutions. The required expertise and limited tool support discourage especially small institutions from operating archives with digital preservation capabilities. Hoppla is an archiving solution that combines back-up and fully automated migration services for data collections in environments w...

to evaluate the effect of adding neoadjuvant chemotherapy to surgery and radiation therapy for locally advanced resectable oral cavity squamous cell carcinoma, 24 patients with t3 or t4a oral cavity squamous cell carcinoma were randomly assigned to surgery alone or docetaxel, cisplatin, and 5-fu (tpf) induction chemotherapy followed by surgery. all patients were planned to receive chemoradiothe...

A quick and simple protocol for long-term cryopreservation of anaerobic ammonium-oxidizing bacteria (anammox bacteria) was developed. After 29 weeks of preservation at -80°C, activity recovery for all tested cultures under at least one of the applied sets of preservation conditions was observed. Growth recovery was also demonstrated for a single-cell culture of "Candidatus Kuenenia stuttgartien...

The preservation of regular tree languages through rewriting, has already been studied. In this paper, we study the preservation of context-free tree languages through rewriting, for constructor-based term rewrite systems. We give positive and negative results. Positive results are effective since we give algorithms to build context-free grammars.

BACKGROUND The question of whether the choice of preservation solution affects outcome after liver transplantation is still not satisfactorily answered. The purpose of this study is to examine the preservation solutions' impact on outcome after liver transplantation. METHODS A double-center retrospective study of short- and long-term results of 3134 consecutive liver transplantations with fol...

When Library Trends devoted its first issue to preservation (Tauber, 1956), the state-of-the-art term was conservation, and the articles dealt with binding, treatments, stack maintenance, and “discarding” (weeding). The focus was almost entirely on libraries, except for an article by Hummel and Barrow on treatment for library and archival material (Hummel & Barrow, 1956). The next Library Trend...
