Digital Archives and Preservation
DEFINITION Preservation is the set of processes that maintain the authenticity, integrity, and chain of custody of records for long periods of time. Authenticity is defined as the management of provenance information about the creation of the record. Integrity is defined as the ability to create an authentic copy. Chain of custody tracks all processing done to the record, including migration to...
متن کاملExceptional preservation of Palaeozoic steroids in a diagenetic continuum
The occurrence of intact sterols has been restricted to immature Cretaceous (~125 Ma) sediments with one report from the Late Jurassic (~165 Ma). Here we report the oldest occurrence of intact sterols in a Crustacean fossil preserved for ca. 380 Ma within a Devonian concretion. The exceptional preservation of the biomass is attributed to microbially induced carbonate encapsulation, preventing f...
متن کاملمطالعات کانی شناسی - ژئوشیمیایی بر روی منطقه کانی سازی شده طلا در کوه زر تربت حیدریه
Shahmirzad village is located on the southern parts of the Eastern Alborz Mountain Ranges. One of the sedimentary rock units that crops out in this area is Soltanieh Formation (Upper Precambrian Lower Cambrian). Thin section and oxygen isotope studies have been used in order to determine the petrological characteristics and the temperature of Soltanieh dolomites formation environment. E...
متن کاملIrradiation’ and its Potential to Food Preservation
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,...
متن کاملMorphological and Geochemical Evidence of Eumelanin Preservation in the Feathers of the Early Cretaceous Bird, Gansus yumenensis
Recent studies have shown evidence for the preservation of colour in fossilized soft tissues by imaging melanosomes, melanin pigment containing organelles. This study combines geochemical analyses with morphological observations to investigate the preservation of melanosomes and melanin within feathers of the Early Cretaceous bird, Gansus yumenensis. Scanning electron microscopy reveals structu...
