ULTRARAPID FREEZING OF MOUSE EMBRYOS
… when employed to make up the 3.5 M DMSO freezing solution. The elevated pH of these solutions in the absence of a 5 % CO2 atmosphere did not have a detrimental effect on the cryosurvival and developmental capacity of the frozen-thawed embryos. Upon comparing the use of phosphate-, Hepes- …

Freezing: An ethnography of crisis reporters
RÉSUMÉ La thèse examine la composition technologique des émotions des journalistes face à une situation de crise. Les émotions liées au travail des journalistes sont au cœur du paradoxe posé, d’une part, par un engagement journalistique traditionnellement en faveur de l'objectivité - celle-ci étant …

Freezing-induced deformation of biomaterials in cryomedicine
… by developing an understanding of underlying freezing-induced biophysical processes. In particular, freezing constitutes the main structural/mechanical origin of cryodamage and results in significant deformation of biomaterials at multiple length scales. Understanding of these freezing-induced …

Surface Freezing in Surfactant/Alkane/Water Systems
Surface freezing transitions in mixed monolayers of a homologous series of cationic surfactants, the alkyltrimethyl ammonium bromides (CnTAB where n = 12, 14, 16, 18), as well as a range of non-ionic, zwitterionic and biological surfactants, have been investigated ellipsometrically with a range of …

Private International Law Aspects of Freezing Injunctions
… is frequently dealing with applications for a freezing injunction. The vast majority of academic literature and court decisions directly or indirectly adopt the view that freezing injunctions have stood the test of time and are so frequently granted in commercial litigation that there is no …

Phase-field simulation of freezing water droplet
When a water droplet freezes on a cold plate, a pointy tip forms as the result of volume expansion. In this dissertation, we will introduce a quasi-compressible phase-field model that deals with this non-isothermal three-phase system involving water, ice, and air. The water-ice phase transition and …

Multiphysics Simulation and Innovative Characterization of Freezing Soils
Freezing soils are significant due to their wide occurrence in nature. A thorough understanding of their behaviors is challenged by their susceptibilities to multiphysical processes as the result of their porous nature. Further advancements in research related to freezing soils call for holistic …

Numerical analysis of the method of freezing traveling waves
In der vorliegenden Arbeit werden spezielle Lösungen von parabolischen partiellen Differentialgleichungen (PDE) u_t = A u_xx + f(u, u_x), nämlich wandernde Wellen der Form u(x,t) = w(x-c t), untersucht. Dabei ist w das Wellenprofil und c die Geschwindigkeit. Das Paar (w,c) lässt sich als …

Carbon dioxide flash-freezing applied to ice cream production
(cont.) Carbon dioxide is recompressed from 1.97 x 106 Pa (285 psi) to 3.96 x 106 Pa (575 psi). The process is scaled by increasing the number of nozzles to accommodate the desired flow rate. Only 165 nozzles are required to flash freeze the ice cream mix at a 2000 L/hr ice cream production rate. …

An experimental investigation of instability in turbulent-flow freezing
… tube wall was conducted. A region of unstable freezing behavior was located and bounded in terms of initial Reynolds number and a nondimensional temperature parameter for the given system. This region was observed over the span of Reynolds numbers from 4500 to 10150 and was defined to exist at …
