purpose: optisol-gs is still the most popular cold storage medium used in the united states for short term preservation of donated corneas. cebi medium is a new cold storage medium made by the central eye bank of iran for donor cornea storage. this study was conducted to compare the quantitative and qualitative indices of the donated corneas maintained in optisol-gs versus in the cebi medium. m...

Thls paper presents a method to measure impact forces on a surface by means of a piezoelectric thin film sensor array. The output signals of the sensor array provide information about the position, magnitude and wave form of the impact force. The sensor array may be used for tribological studies to the slider disk interface of a rigid disk storage device. In such a device a slider head assembly...

We present an overview of our recent research efforts on read–write volume holographic digital data storage. High areal density (394 bits/square micron) holographic data storage, and a novel system architecture for extending this high density to high capacity are described. We also discuss signal–processing of data pages to compensate for pixel shifts, and two–color gated storage media to provi...

Digital data explosion drives a demand for robust and reliable data storage medium. Development of better digital storage device to accumulate Zetta bytes (1 ZB = 1021 bytes ) of data that will be generated in near future is a big challenge. Looking at limitations of present day digital storage devices, it will soon be a big challenge for data scientists to provide reliable. affordable and dens...

Background and Objective: The quality of flat breads depends in part on the textural and structural properties of breads during storage. These properties are largely affected by flour quality. This research aimed at evaluating textural and structural properties of Lavash bread types during storage by different techniques, comparing these methods and determination of correlation between their re...

This experimental study suggests an alternative method of data deletion which can be considered secure up to an acceptable level for most purposes while maintaining anti-forensics characteristics. It is a quick and “dirty” solution to remove data from a storage medium while achieving to confuse the investigator about the contents of the i.e. the hard disk. More specifically, working upon the fi...

By comparing the composition of McCarey-Kaufman (MK) medium before and after corneal storage we attempted to identify specific physiological changes in the medium as predictors of tissue damage. We also tried to determine if hydrocortisone (a lysosomal membrane stabiliser) added to the medium could reduce tissue damage during storage. Corneas (human and rabbit) were stored in the MK medium with...

The present study demonstrates the potential of nutrient-alginate encapsulation of shoot tips of sunflower, Helianthus annuus (hyb. Azargol) for synthetic seed technology, which could be useful in germplasm distribution and exchange. Shoot tips from in vitro shoot cultures derived from mature seed explants were encapsulated in 3% sodium alginate and 100 mM CaCl2. 2H...
