The Copyright Subgroup noted that archives and museums may face a number of problems in connection with digitalpreservation and access which are peculiar to them. The costs of digitisation tend to be higher in connection with multimedia and audiovisual works than for text; and the number of users accessing the premises of archives and museums may be substantially lower than in the case of libraries. Additionally, audiovisual works entail the need for clearances by vast numbers of rightholders, including holders of related rights. Issues of privacy and of right of publicity may also frequently arise. Typically these more complex situations should be dealt with in what sometimes is described as a “second basket” of measures, on the basis of experience accumulated in more traditional contexts, such as text. However, the Subgroup surmises that even in this area mechanisms intended to facilitate the use of works held in archives and museums can be established or promoted on a voluntary basis. Collective licensing may be actively encouraged; it may, depending on the context, concern digitisation, access, or, under given circumstances, even commercial uses to the extent that they do not compete with the primary exploitation of works.
The OAIS model has a set of requirements and recommendations that organiza- tions should follow to mitigate or address the issue of preserving digital information for long periods of time (long-term or permanently). It is known that digital infor- mation can easily be lost or corrupted. At production of digital information time, we have privileged access to data and on how that information is produced (meta- data). So if organizations have an active role when producing their own data and start to consider the preservation of it, they will certainly have future benefits. Due to various factors, the production of digital information increases every day, which means that in many cases the roles of the producer of information and the responsi- ble for archiving that information, are merged into the same individual. The digitalpreservation concerns are often relegated to second plan, increasing costs that will only be felt in the future. Designers and system developers should take into con- sideration the extreme importance of documenting the generated information, yet it is easy to realize that this often collides with market objectives for rapid produc- tion and dissemination of products to their consumers [Consultative Committee for Space Data Systems, 2002].

The present work entitled Institutional Repositories: An alternative for digitalpreservation, studied different existing digitalpreservation projects necessary to create institutional repositories facilitating access to their collections at short, medium and long term. In order to do this, a theoretical approach to the concepts of digitalpreservation and institutional repositories was made. The challenges faced by information institutions in the context of digitalpreservation were exposed, and the digitalpreservation projects to be studied in order to design preservation – oriented institutional repositories were identified. The research was carried out following a methodology of a qualitative and descriptive nature in order to meet the objectives set. The main output obtained was that for the design and implementation of an institutional repository oriented to preservation it is necessary to take as a reference international and national standards, reports and existing digitalpreservation projects such as: the OAIS model, the Premis metadata system and the METS scheme, the Charter for the preservation of UNESCO's digital heritage, the Guidelines for the preservation of digital heritage of the National Library of Australia, the Digital Repository Audit Method Based on the Risk Assessment (DRAMBORA) and the Management of the Documentary Repository of the University of Salamanca (GREDOS). With this research, the following conclusion was reached: digitalpreservation should be a concern for everybody, since the preservation of the universal digital memory of mankind is at stake.

We consider important to catalogue these environments, in order to record their sounds with an adequate equipment, not only for having digital quality, but to study those sounds, to know the physical aspects of them, and their acoustics indexes. The recording of this heritage would allow, in principle, its “preservation”; the existence of a record library of the natural and rural environments in Extremadura.

The need for optimizing preservation and rehabilitation strategies used to maintain the Nation’s highway pavements has never been greater. Concrete overlays have a long history of use to preserve and rehabilitate concrete and asphalt pavements, and many of the practices are well established. However, of recent origin are techniques that use thinner concrete overlays with shorter joint spacing. Field experience over more than 15 years with the thinner concrete over- lays under a range of traffic and site conditions has demonstrated their viability as a cost- effective solution to extend the service life of deteriorated asphalt and concrete pavements. The Federal Highway Administration (FHWA) has initiated several activities to support tech- nology transfer related to concrete overlays. These activities include reviews, on a regional or statewide basis, of current applications of concrete overlays, identification of gaps in technol- ogy, and assistance in developing a program—jointly with State departments of transportation (DOTs) and industry—for technology transfer and demonstration projects. This paper provides a review of thin concrete overlays applied as bonded or unbonded overlays. In addition, three
The preservation of delicate morphological elements, such as the eyes, is extremely rare in the fossil record of brachyuran crustaceans. Most of the few records come from Lagerstätten deposits, where paleoenvironmental, sedimentological, taphonomic and diagenetic conditions propitiated preservation of delicate structures. In particular, eye preservation in fossil decapods is unusual, with just a few reports (Imaizumi, 1957, 1965; Glaessner, 1969; Feldmann et al., 2008; Tanaka et al., 2009; Luque, 2012). The evolutionary significance of eye structure in decapods crustaceans has been discussed by several authors (Gaten
The aim of this work was to study steam explosion as a pretreatment for commercial cellulose samples presented in two different handlings, to explore the possibilities of this treatment as a substitute for other mechanical pretreatments and its effects on the modification of several physicochemical properties of cellulose fibers regarding a future use. To that end, several analyses were performed such as chemical composition, particle size distribution, crystallinity rate, limiting viscosity number and degree of polymerization. In addition, two different preservation methods of pretreated samples (acetone washing and freezing) were tested to study the effects of preservation methods could have on the stability and quality of pretreated samples.

The main aim of this research is quantification and evaluation through monitoring and simulation models of the hygrothermal parameters of three churches in southern Spain, (Mediterranean climate) following the combined implementation of active environmental techniques (HVAC) and passive techniques for reducing energy consumption. Moreover, their impact on the preservation of property, thermal occupant comfort, and energy consumption are also analysed simultaneously in order to obtain references about the case study located in a temperate climate.
Preservation of normal sleep, proper nutrition and physical exercise are key elements in maintaining healthy aging. Their deficiency predisposes to fragili- ty, a pathophysiological condition that leads to greater vulnerability to diseases and adverse effects, resulting from the loss of homeostasis and a decreased func- tional reserve. Melatonin, a molecule of extraordinary phylogenetic conservation present in all known aero- bic organisms, is effective both as a chronobiotic and a cytoprotective agent in aging. The late afternoon increase of melatonin “opens the sleep doors” every night and its therapeutic use as a guardian of slow wave sleep has been demonstrated. There is a grow- ing use of hypnotics such as benzodiazepines (BZP) and Z drugs, which have shown a deleterious effect on slow wave sleep and, due to their tolerance and dependence, are a serious problem of public health. Thirty years ago, we demonstrated the interaction of melatonin with central BZP receptors and in 1997 we published the first demonstration of the reduction of BZP consumption in melatonin-treated elderly subjects. The approval by the EMA of melatonin as a drug in 2007 has allowed obtaining pharmacoepi- demiologic information on this topic. Several stud- ies have found that more than half of patients treat- ed with BZP and who had started treatment with melatonin abandoned BZP consumption. In another study in 9 European countries it was concluded that
