An Innovation in Magnetic Field Assisted Freezing of Perishable Fruits and Vegetables: A Review

, 2020
Freezing is an important preservation technique to preserve the raw food and to extend the shelf life for longer duration of time by reducing the product temperature to −18°C or below. Effectiveness of freezing depends on size, shape, distribution of ice

Arabidopsis CBF1 overexpression induces COR genes and enhances freezing tolerance.

Science, 1998
Many plants, including Arabidopsis, show increased resistance to freezing after they have been exposed to low nonfreezing temperatures. This response, termed cold acclimation, is associated with the induction of COR (cold-regulated) genes mediated by the

Freezing

Science, 1987
There is no first principles theory of freezing or melting, even for the simplest materials. The prediction of phase diagrams is an important first step in understanding the crystal-melt interface, crystallization near equilibrium, and nucleation. Recently, a new approximate theory for the freezing of classical liquids, known as the density functional ...

Freezing in it-clefts

Canadian Journal of Linguistics/Revue canadienne de linguistique, 2013
Freezingis the cover term for the restriction on extraction from constituents in a derived position. The traditional Freezing cases are illustrated here with topicalization in (1a), heavy-NP shift in (1b), and extraposition in (1c).

On swap rate dynamics: to freeze or not to freeze?

International Journal of Computer Mathematics, 2015
We explore the implications of a common market and academic practice which is known as ‘freezing the drift’ when dealing with swap interest rate dynamics. In mathematical terms this can be better understood as imposing a low variance martingale (LVM) assumption.

Using power ultrasound to accelerate food freezing processes: Effects on freezing efficiency and food microstructure

Critical reviews in food science and nutrition, 2018
Freezing is an effective way of food preservation. However, traditional freezing methods have the disadvantages of low freezing efficiency and generation of large ice crystals, leading to possible damage of food quality.

Pore Structure in Coal: Pore Evolution after Cryogenic Freezing with Cyclic Liquid Nitrogen Injection and Its Implication on Coalbed Methane Extraction

, 2016
Freezing and thawing cycles occur with cyclic liquid nitrogen (LN2) injection in coal. The freeze–thaw treatment damages the pore structure of coal and thus increases its permeability. In this study, NMR and strain monitoring were employed to investigate

Winter Archaeology: To Freeze or not To Freeze

American Antiquity, 1956
Once in a while in American archaeology, funds limited by an expiration date or a pressing need for information before site destruction demand carrying on field operations during winter months. When either or both emergencies occur — both did in the 1954-55 winter at historic Jamestown, in Colonial National Historical Park — certain questions arise as ...

Freeze-Substitution and Freeze-Drying

1987
Freeze-substitution (FS) and freeze-drying (FD) are dehydration techniques by which the water is gently removed from a frozen specimen. Both techniques can serve as a link between cryofixation and conventional thin sectioning at room temperature (Fig. 1).
