Determination of Heat Transfer Coefficients for French Plastic Semen Straw Suspended in Static Nitrogen Vapor Over Liquid Nitrogen
(Cryo Letters, 2015-12)
BACKGROUND: The use of mathematical models describing heat transfer during the freezing process is useful for the improvement of cryopreservation protocols. A widespread practice for cryopreservation of spermatozoa of ...
How important are internal temperature gradients in french straws during freezing of bovine sperm in nitrogen vapor?
(Cryo Letters, 2013-03)
The subject of present work was to predict internal temperature gradients developed during freezing of bovine sperm diluted in extender, packaged in 0.5 ml French plastic straws and suspended in static liquid nitrogen vapor ...
Determination of heat transfer coefficients in plastic French straws plunged in liquid nitrogen
(Academic Press Inc Elsevier Science, 2014-10)
The knowledge of the thermodynamic process during the cooling of reproductive biological systems is important to assess and optimize the cryopreservation procedures. The time-temperature curve of a sample immersed in liquid ...
Comparison of heat transfer in liquid and slush nitrogen by numerical simulation of cooling rates for French straws used for sperm cryopreservation
(2011)
Abstract: Slush nitrogen (SN2) is a mixture of solid nitrogen and liquid nitrogen coexisting under an average temperature of -207ºC. In order to investigate whether plunging a French plastic straw (commonly used for ...
