Deformation of C15 Laves Phase Alloys [PDF]

MRS Proceedings, 1994
AbstractDetails of the structure and previous work on the deformation of C15 Laves phases are reviewed. The phase diagram of the Hf-V-Nb system, some metallurgical and physical properties, mechanical behavior, and the deformation mechanisms of HfV2+Nb (C15 HfV2+Nb and V-rich bcc solution) are presented based on our previous work. Theoretical approaches

Animal welfare index: an animal welfare evaluation of beef production farms in Ireland

Journal of Applied Animal Research, 2022
The study objective was to examine the animal welfare status of Irish beef production farms using an animal welfare index (AWI). Beef production farms (n = 105) including suckler calf-to-beef (n = 30), suckler calf/weaning/finishing (n = 63), dairy calf ...

Effect of Post-Grazing Sward Height, Sire Genotype and Indoor Finishing Diet on Steer Intake, Growth and Production in Grass-Based Suckler Weanling-to-Beef Systems

Animals, 2021
This study evaluated the effects of post-grazing sward height (PGSH, 4 or 6 cm) on herbage production, its nutritive value, dry matter (DM) intake, grazing behaviour and growth of early- (EM) and late-maturing (LM) breed suckler steers (n = 72), and the ...

Enhancing early life nutrition alters the hepatic transcriptome of Angus × Holstein-Friesian heifer calves

Animal, 2022
Early life nutrition has a major influence on subsequent lifetime performance in cattle. The aim of this experiment was to investigate the effect of plane of nutrition from 3 to 21 weeks of age on the liver transcriptome. Holstein-Friesian × Angus heifer

Genome-wide association study of economically important traits in Charolais and Limousin beef cows

Animal, 2021
Genomic selection has proven effective for advancing genetic gain for key profit traits in dairy cattle production systems. However, its impact to-date on genetic improvement programs for beef cattle has been less effective.

C15 intermetallic compounds HfV{sub 2}+Nb [PDF]

, 1994
Phase fields and equilibria in the Hf-V-Nb system were determined using a combination-of SEM, EDS and x-ray diffraction. The structural stability of the C15 HfV{sub 2+}Nb was studied by x-ray diffraction and specific heat measurements.

Mitochondrial abundance and function in skeletal muscle and liver from Simmental beef cattle divergent for residual feed intake

Animal, 2020
Cellular mitochondrial function has been suggested to contribute to variation in feed efficiency (FE) among animals. The objective of this study was to determine mitochondrial abundance and activities of various mitochondrial respiratory chain complexes (
