Holographic study of frost damage
Physics Bulletin, 1988Frost related damage in concrete can seriously affect the durability of structures such as bridge decks, retaining walls and dams. Nondestructive tests can quantify the effect of frost exposure, through measuring changes in the length or elastic characteristics of the specimen, and ultrasonic methods are also used but these tests do not give a global ...

STORABILITY OF FROST-DAMAGED CANOLA
Canadian Journal of Plant Science, 1984Changes in the quality of frost-damaged canola seeds (Brassica napus L. and B. campestris L.) from 21 bins in Manitoba were studied on four occasions (Rounds 1 to 4) during October 1982 to April 1983. Twenty-two quality parameters were assessed on seed samples obtained at two bin depths on each sampling occasion.

Feeding value of frost-damaged soybeans for lambs
Journal of Animal Science, 1992Three experiments were conducted to determine the relative feeding value of frost-damaged soybeans (FDS) for ruminants. Frost-damaged soybean ether-extract content was variable and differed (P less than .05) from mature soybeans. Isonitrogenous supplementation of corn silage diets with soybean meal (SBM), SBM+soybean oil (SBO), mature raw soybeans (MSB)

Plant Pathology, 1979
SUMMARY Widespread damage attributed to frost lift was seen in winter barley crops in Devon and Cornwall during late spring 1978. A break in the crown root system of plants had occurred. An affected crop of cv. Astrix in Devon yielded 3.5 t/ha; this was 1.8 t/ha less than an adjacent unaffected crop of the same cultivar.

Journal of Forestry, 1933
Abstract The author describes frost injury to the tops of 15-year-old red pine trees growing in a plantation at Keene, New Hampshire, and discusses its physiology. The method of recovery and resultant deformity is described in detail and illustrated with photographs and diagrams.

Frost Damage to White Spruce Buds
Canadian Journal of Forest Research, 1972Unopened buds of white spruce (Piceaglauca (Moench) Voss) were damaged by late spring frost. At time of death of the apical meristem the buds were not ready for flushing. As expected on the basis of ground frosts, there was more damage among shorter trees than among taller trees, and more damage among open-grown trees than among understory trees.

On the mechanics of frost damage to brick masonry
Computers & Structures, 1991Abstract This paper presents a computational model for the assessment of frost damage to brick masonry. Equivalent elastic parameters of masonry with brick units having orthotropic properties is first derived. It is then extended to frozen brick masonry by including ice within the pores.

Research on the disturbance of frost damage to forests
Acta Ecologica Sinica, 2013The occurrence of frost damage in forest did not show any decrease trends in the condition of global climate warming,the growing season frost could lead severely damage to the tissues of trees and the whole seedlings.Thus,the frost is becoming one of the major limiting factors for tree growth and regeneration.The occurrence and degree of frost damage ...

Australian Journal of Agricultural Research, 1956
Detailed temperature measurements among grape-vines, and in the inversion layer in the air overhead, are presented for two nights on which frost damage occurred. The temperatures are related to the varying degrees of damage suffered by the vines. It is concluded that the critical vine-shoot temperature was about 28½°F a t the stage of development of ...

Can microfibers prevent frost damage?
Cement and Concrete Research, 1996Abstract To analyze the influence of microfibers on the durability of frost susceptible cementitious systems, eight paste mixtures and eight mortars were batched under vacuum. Such a procedure was found to reduce very significantly the volume of air entrapped in the micro-reinforced pastes and mortars during the mixing process.
