Grain crop breeding for immunity in the North-East of the European Territory of Russia by G. A. Batalova

“…The variety ‘Medved’ is tolerant to frit flies (oscinis frit), weakly responsive to loose smut in the laboratory infectious conditions and resistant in natural conditions; the variety has got only 0.8% of damage made by root rot. The barley variety ‘Ekolog’ is resistant to loose and kernel smut, weakly responsive to stripe blotch and tolerant to root rot. …”

Mechanical properties of raw bamboo fiber-reinforced phosphogypsum-based composite cementitious materials and their strengthening mechanism. by Xian Fu, Peng Liu, Dewen Kong, Yuan Li, Yongfa Wang

“…Secondly, the effects of the length and content of raw bamboo fibers on the mechanical properties of BFRPGCs at this optimal water-cement ratio were examined, along with an exploration of the mechanisms by which raw bamboo fibers impact the mechanical properties of the composites, considering their damage modes. Finally, the microstructure of BFRPGCs was analyzed using scanning electron microscopy (SEM), which elucidated the mechanisms through which raw bamboo fibers influence the working and mechanical properties of the composites. …”

Strength and Microscopic Damage Mechanism of Yellow Sandstone with Holes under Freezing and Thawing by Huren Rong, Jingyu Gu, Miren Rong, Hong Liu, Jiayao Zhang, Hao Dong

“…The results show the following. (1) The number of freeze-thaw cycles and single-pore diameter have significant effects on the strength and elastic modulus of the yellow sandstone; the more the freeze-thaw cycles and the larger the pore size, the lower the strength of the yellow sandstone. (2) The damage modes of the yellow sandstone containing pores under the freeze-thaw cycle are divided into five types, and the yellow sandstone with pores is divided into two areas: the periphery of the hole and the distance from the hole; as the number of freeze-thaw cycles increases, different regions show different microscopic damage patterns. (3) The damage degree of yellow sandstone is different with freeze-thaw cycle and pore size. …”
