Long Term Preservation

The purpose of the analysis is to demonstrate the effectiveness of Piql technology data storage for long-term preservation. This technology has been confirmed by certified laboratory tests. The article presents a unique and effective technology for perpetual storage of data on physical media and a detailed description of data recording methods, including the equipment needed for this process. It also presents the conditions of packaging, storage, transport and protection of piqlFilm media, based on the experience of durability of this medium over the past several decades. The idea behind the creation of this technology, in addition to permanent storage, is the ability to read the stored data in the distant future. The data is stored in an open format, allowing read access without temporal or technological limitations. Piql has also, taking advantage of the unique geo-climatic conditions on the Arctic island of Svalbard, established a specialized archive called the Arctic World Archive or the End of the World Library, to store the most valuable data of international institutions and companies as well as the world’s cultural heritage.

Abstract. To date, terrestrial archives of long-term climatic change within the Arctic have widely been restricted to ice cores from Greenland and, more recently, sediments from Lake El'gygytgyn in northeast Arctic Russia. Sediments from this lake contain a paleoclimate record of glacial-interglacial cycles during the last three million years. Low-resolution studies at this lake have suggested that changes observed during Transition IV (the transition from marine isotope stage (MIS) 10 to MIS 9) are of greater amplitude than any observed since. In this study, geochemical parameters are used to infer past climatic conditions thus providing the first high-resolution analyses of Transition IV from a terrestrial Arctic setting. These results demonstrate that a significant shift in climate was subsequently followed by a rapid increase in biogenic silica (BSi) production. Following this sharp increase, bioproductivity remained high, but variable, for over a thousand years. This study reveals differences in the timing and magnitude of change within the ratio of silica to titanium (Si/Ti) and BSi records that would not be apparent in lower resolution studies. This has significant implications for the increasingly common use of Si/Ti data as an alternative to traditional BSi measurements.

Direct Attack

The campaign in the Punjab saw Alexander, supported by his Indian ally Taxiles, attack Porus, who lived beyond the Hydaspes River. The battle, at the beginning of the monsoon season, involved a division of the Macedonian forces. One part faced Porus at the river crossing, where the current and the elephants in the Indian army made a direct attack virtually impossible. Alexander took a portion of his army and marched upstream. Once across the river, he drew Porus away from his defensive position and defeated the Indian ruler in a battle fought primarily by cavalry, although the Macedonian pikemen inflicted injuries on the elephants, which became a danger to their own troops. After the Hydaspes victory, Alexander advanced to the Hyphasis (Beas), where the army refused to cross in order to march to the Ganges. The whole episode was contrived, since Alexander clearly had no intention of going farther east. His failure to reach the eastern end of the world was thus attributed to the timidity and war-weariness of his soldiers. During the descent of the Indus river system, Alexander received a near-fatal wound at the hands of the Mallians. Once he recovered, Alexander conducted a series of bloody massacres as he sailed to the mouth of the Indus and accomplished his goal of sailing out into the ocean. Although the Indian campaign was by far the bloodiest of the expedition, there was little long-term gain from the conquest.

Abstract. The long-term frequency of atmospheric dust observations was investigated for the southern part of Iceland and interpreted together with earlier results obtained from northeastern (NE) Iceland (Dagsson-Waldhauserova et al., 2013). In total, over 34 dust days per year on average occurred in Iceland based on conventionally used synoptic codes for dust observations. However, frequent volcanic eruptions, with the re-suspension of volcanic materials and dust haze, increased the number of dust events fourfold (135 dust days annually). The position of the Icelandic Low determined whether dust events occurred in the NE (16.4 dust days annually) or in the southern (S) part of Iceland (about 18 dust days annually). The decade with the most frequent dust days in S Iceland was the 1960s, but the 2000s in NE Iceland. A total of 32 severe dust storms (visibility < 500 m) were observed in Iceland with the highest frequency of events during the 2000s in S Iceland. The Arctic dust events (NE Iceland) were typically warm, occurring during summer/autumn (May–September) and during mild southwesterly winds, while the subarctic dust events (S Iceland) were mainly cold, occurring during winter/spring (March–May) and during strong northeasterly winds. About half of the dust events in S Iceland occurred in winter or at sub-zero temperatures. A good correlation was found between particulate matter (PM10) concentrations and visibility during dust observations at the stations Vík and Stórhöfði. This study shows that Iceland is among the dustiest areas of the world and that dust is emitted year-round.

Abstract. Long-term frequency of atmospheric dust observations was investigated for the southern part of Iceland and merged with results obtained from the Northeast Iceland (Dagsson-Waldhauserova et al., 2013). In total, over 34 dust days per year on average occurred in Iceland based on conventionally used synoptic codes for dust. Including codes 04–06 into the criteria for dust observations, the frequency was 135 dust days annually. The Sea Level Pressure (SLP) oscillation controlled whether dust events occurred in NE (16.4 dust days annually) or in southern part of Iceland (about 18 dust days annually). The most dust-frequent decade in S Iceland was the 1960s while the most frequent decade in NE Iceland was the 2000s. A total of 32 severe dust storms (visibility < 500 m) was observed in Iceland with the highest frequency during the 2000s in S Iceland. The Arctic dust events (NE Iceland) were typically warm and during summer/autumn (May–September) while the Sub-Arctic dust events (S Iceland) were mainly cold and during winter/spring (March–May). About half of dust events in S Iceland occurred in winter or at sub-zero temperatures. A good correlation was found between PM10 concentrations and visibility during dust observations at the stations Vik and Storhofdi. This study shows that Iceland is among the dustiest areas of the world and dust is emitted the year-round.

AbstractCommon carp (Cyprinus carpio) is one of the most cultured fish species over the world with many different breeds and plenty of published protocols for sperm cryopreservation, however, data regarding preservation of gonadal tissue and surrogate production is still missing. A protocol for freezing common carp spermatogonia was developed through varying different factors along a set of serial subsequent experiments. Among the six cryoprotectants tested, the best survival was achieved with dimethyl sulfoxide (Me2SO). In the next experiment, a wide range of cooling rates (0.5–10 °C/min) and different concentrations of Me2SO were tested resulting in the highest survival using 2 M Me2SO and cooling rate of –1 Q59 A When testing different tissue sizes and incubation times in the cryomedium, the highest viability was observed when incubating 100 mg tissue fragments for 30 min. Finally, sugar supplementation did not yield significant differences. When testing different equilibration (ES) and vitrification solutions (VS) used for needle-immersed vitrification, no significant differences were observed between the tested groups. Additionally, varied exposure time to VS did not improve the vitrification outcome where the viability was 4-fold lower than that of freezing. The functionality of cryopreserved cells was tested by interspecific transplantation into sterilized goldfish recipients. The exogenous origin of the gonads in goldfish recipients was confirmed by molecular markers and incorporation rate was over 40% in both groups at 3 months post transplantation. Results of this study can serve as an alternative way for long-term preservation of germplasm in carp which can be recovered in a surrogate recipient.

Linear Trends

New estimates of linear trends in the position of the level surface were obtained as a result of analysis of the data of long-term observations of sea level fluctuations at the stations of the seas of the Arctic Ocean. A rise in sea level is observed at almost all stations. In multi-year fluctuations of the level, periods characterized by different values of linear trends are identified. The reasons for the variability of local linear trends in the level of the Arctic seas from the 1950-1980 stage to the 1990-2015 period are analyzed. It is shown that the presence of local trends during the annual average levels at coast stations is a consequence of changes in climatic conditions reflected in changes in atmospheric and hydrosphere climatic indices, as well as in freshwater river runoff.

As the digital world unfolds, Africa continues to grapple with the issues of preservation and access of digital materials. This chapter demonstrates through a systematic literature review how Africa could learn from other efforts in the world to develop and guide their own strategic and policy options to deal with issues of preservation and access of digital materials. The chapter reviews literature on global or universal collaborative strategies and efforts on digital preservation initiated in the developed world as a learning curve for Africa. The current challenges of national and institutional capacities regarding the preservation of digital materials in selected African countries that have made some visible efforts and impact are also discussed. The chapter then makes several recommendations on the strategic and policy options for improving the state of material preservation, human and material requirements in order to improve the long-term preservation, and standards for the longer-term usability and interoperability of digital materials in Africa.

Long Term Preservation

In an era of global change, the process of biotic homogenisation by which regional biotas become more similar through time has attracted considerable attention from ecologists. Here, a retrospective look at the literature is taken and the question asked how comprehensive is the understanding of this global phenomenon? The goal is to identify potential areas for additional and future enquiries to advance this research frontier and best ensure the long-term preservation of biological diversity across the world. Six propositions are presented here to; (1) broaden our geographic and taxonomic understanding, (2) diversify the spatial and temporal scales of inquiry, (3) reconcile past and embrace new approaches to quantification, (4) improve our knowledge of the underlying drivers, (5) reveal the conservation implications and (6) forecast future homogenisation. It is argued that significant progress in the understanding of the causes, consequences and conservation implication of biotic homogenisation will come by integrating concepts and approaches from ecology, evolution and conservation across a hierarchy of spatial and temporal scales.
