Sixty one corneas taken from 33 hepatitis B surface antigen (HBsAg) seropositive donors and 20 control corneas taken from 12 HBsAg seronegative donors were tested for the presence of HBsAg using reversed passive haemagglutination (RPHA) and enzyme linked immunosorbent assay (ELISA) and for the presence of hepatitis B virus core DNA (HBVcDNA) using the hybridisation technique in their epithelium...

Distributed storage systems running on clusters of commodity hardware are challenged by the ever-growing data storage and I/O demands of modern large-scale data analytics. A promising trend is to exploit the recent improvements in memory, storage media, and network technologies for sustaining high performance at low cost. While recent work explores using memory and SSDs as a cache for local sto...

Carbon dioxide capture and geological storage is an enabling technology that will allow the continued use well into this century of fossil fuels, mainly coal, for power generation and combustion in industrial processes because they are relatively abundant, cheap, available and globally distributed, thus enhancing the security and stability of energy systems. Geological media suitable for CO2 st...

In this paper, we present SGDB, a graph database with a storage model optimized for computation of Spreading Activation (SA) queries. The primary goal of the system is to minimize the execution time of spreading activation algorithm over large graph structures stored on a persistent media; without pre-loading the whole graph into the memory. We propose a storage model aiming to minimize number ...

MEMS-based storage devices should be energy efficient for deployment in mobile systems. Since MEMS-based storage devices have a moving media sled, they should be shut down during periods of inactivity. However, shutdown costs energy, limiting the applicability of aggressive shutdown decisions. The media sled in MEMS-based storage devices is suspended by springs. We introduce a policy that explo...

As patients face the possibility of copying and keeping their electronic health records (EHRs) through portable storage media, they will encounter new risks to the protection of their private information. In this study, we propose a method to preserve the privacy and security of patients' portable medical records in portable storage media to avoid any inappropriate or unintentional disclosure. ...

Magnetic recording currently is the major data storage technology. Conventional magnetic media implement continuous magnetic layers consisting of microscopic grains. Such media have constraints of thermal instability due to the superparamagnetic effect, which occurs when the magnetic grains become too small. The superparamagnetic effect may set the fundamental limit of about 0.5Tbit/inon achiev...

The effect of suspending media on the stability of pseudorabies virus upon freeze-drying and subsequent storage was studied. A variety of media was tested, including: sodium glutamate; sucrose; lactose; lactalbumin hydrolysate; peptone; a combination of sucrose, dextran, and glutamate; and various combinations of sucrose, glutamate, and potassium phosphates. Suspending media containing glutamat...
