Sodalite as a vehicle to increase Re retention in waste glass simulant during vitrification

P-121: Which Developmental Stage is Suitable for Re-vitrification? Compact Stage Re-vitrification or Early Blastocyst Stage Re-vitrification

Background: The aim of this study was evaluation of developmental rate and Bax, Bcl-2 and ErbB4 genes expression following re-vitrification in compact and early blastocysts stages. Materials and Methods: 5-8 cell embryos were collected from female mature mice, 60-62 hours post hCG injection. The embryos were divided to five groups including: fresh, vitrified at 5-8 cells, vitrified at blastocys...

Preop as a Tool to Increase Student Retention in Cs

The demand for computer scientists is expected to continue to increase irrespective of the current state of the economy. Unfortunately, the supply is not expected to match the demand as the number of computer science majors has decreased substantially since the year 2000. As a result, universities and colleges are attempting to identify new ways to attract and retain prospective students into t...

Vitrification of copper flotation waste.

The vitrification of an hazardous iron-rich waste (W), arising from slag flotation of copper production, was studied. Two glasses, containing 30wt% W were melted for 30min at 1400 degrees C. The first batch, labeled WSZ, was obtained by mixing W, blast furnace slag (S) and zeolite tuff (Z), whereas the second, labeled WG, was prepared by mixing W, glass cullet (G), sand and limestone. The glass...
