Freeze and Frost Protection with Aqueous Foam— Field Experiments

Directionally freeze-cast titanium foam with aligned, elongated pores

Directional freeze-casting – a process used to create foams with elongated, aligned pores applied so far exclusively for ceramics – is demonstrated for titanium foams. An aqueous slurry of <45 lm titanium powders was directionally solidified, resulting in a powder preform consisting of elongated, aligned dendrites of pure ice separated by interdendritic regions with high powder content. After f...

Berry and Froscher: Foam-mat and Freeze Dried

Cold pressed peel oil was added to high quality 50°Brix commercial orange concentrate and foam-mat dried, or diluted to single strength juice and freeze-dried using different platen temperatures. Amounts of peel oil ranged from 0.026% to 0.106% for samples to be foam-mat dried, and from 0.011% to 0.109% for freeze drying. For foam-mat drying, previously de veloped standard commercial conditions...

Evaluation the Resistance of Almond to Frost in Controlled and Field Conditions

Frost damage to the flowers and early developing fruits is one of the most limiting factors in the most almond cultivation regions of the world. This study was undertaken to help understand almond response to frost spring at same phenological stage, in order to develop criteria for the selection of cultivars with improved resistance to frost on the basis of field and laboratory experiments. In ...

Field Experiments with Atebrin and Plasmochin

Behala, a village about six miles from Calcutta, and have been treated in the Carmichael Hospital for Tropical Diseases. We have from time to time visited this settlement, as it was thought that a study of the conditions might throw some light on the transmission problem. Except that they are more sanitary, the general conditions under which these boys live are very similar to those prevailing ...
