Limiting Partition Coefficient in a Tubular Ice System for Progressive Freeze-concentration

Prevention of Initial Supercooling in Progressive Freeze-concentration.

A physical method is proposed that uses a cooling plate with many small holes to prevent initial supercooling in progressive freeze-concentration, and thus avoid serious contamination of the ice produced. The higher chance for ice nucleation of the water molecules in the holes due to the temperature gradient in the cooling plate resulted in the initial supercooling being completely prevented. A...

EXPERIMENTALl ANALYSIS OF PARTITION COEFFICIENT IN Al-Mg ALLOYS

Because the partition coefficient is one of the most important parameters affecting microsegregation, the aim of this research is to experimentally analyse the partition coefficient in Al-Mg alloys. In order to experimentally measure the partition coefficient, a series of quenching experiments during solidification were carried out. For this purpose binary Al-Mg alloys containing 6.7 and 10.2 w...

Sea Ice Concentration Estimation during Freeze-Up from SAR Imagery Using a Convolutional Neural Network

In this study, a convolutional neural network (CNN) is used to estimate sea ice concentration using synthetic aperture radar (SAR) scenes acquired during freeze-up in the Gulf of St. Lawrence on the east coast of Canada. The ice concentration estimates from the CNN are compared to those from a neural network (multi-layer perceptron or MLP) that uses hand-crafted features as input and a single l...

Effective Parameters on the Partition Coefficient of Guanidine Hydrochloride in the Poly (Ethylene Glycol) +Phosphate +Water System at 298.15 K

Ice Nucleation in Freeze - Tolerant Vertebrates

The survival of freeze-tolerant vertebrates requires that ice nucleation in tissues be initiated at relatively high temperatures. Three current hypotheses for the initiation of freezing in these animals are: a) inoculation by contact with ice crystals in the external environment; b) nucleation by ice-nucleating bacteria associated with the animal; and c) nucleation by icenucleating proteins in ...
