Functional and Its Variational Principle in Thermal Inelasticity
Cheng, Heming,Wang, Honggang,Huang, Xieqing 대한금속재료학회(대한금속학회) 1998 METALS AND MATERIALS International Vol.4 No.4
The heat conduction equation in a coupled thermo-inelastic body, was derived by means of the irreversible thermodynamics and the measured data of the inner dissipation for metal. The coupled coefficients, which are dependent on temperature and inelastic strain rate, can be determined by the measured data of inner dissipation for metal. The functional of a coupled thermal inelastic problem was derived by means of nonlinear functional analysis theory. Finally, it is proved that the critical points of the functional are the solutions of coupled thermal inelastic equations.

The thermal physical properties were treated as a functions of temperature. On the basis of non-linear surface heat-transfer coefficient by Ref. [2], the temperature field with non-linear surface heat-transfer coefficients was calculated using finite clement technique. The experimental results of temperature field coincide with numeral solutions. Finally, the thermal stress was calculated by means of finite element method.

Ubiquinol-cytochrome c reductase complex chaperone (UQCC) involved in the development and maintenance of bone and cartilage is an important candidate gene for body measurement traits selection through marker-assisted selection (MAS). The expression of UQCC is upregulated in many human and animal models of height as well as other stature indexes. We have cloned the cDNA sequence coding UQCC gene in bovine. Genomic structural analysis indicated that bovine UQCC shares a high similarity with human UQCC. Furthermore, Real-Time PCR analysis showed that the expression of bovine UQCC is remarkably different in diverse tissues, including high level expression in the spleen, heart and windpipe, and relatively low expression in other tissues. We also analyzed allele frequencies in different cattle breeds and an association study on the selected SNPs. SNP DraI A2691T in intron 1 and SNP Bsh1236I A3150G in intron 8 are significantly associated with Body Length (BL), Rump Length (RL), Chest Depth (CD) and Pin Bone Width (PBW). For the A2691T SNP marker, there are significant effects on the RL (p = 0.0001), CD (p = 0.0059) and PBW (p < 0.0001) in 679 individuals; with A3150G SNP marker, there are significant effects on the BL (p = 0.0047) and CD (p = 0.0454). Regarding association analysis of combination of the two SNPs, there are significant effects on the BL (p = 0.0215), CD (p = 0.0282) and PBW (p = 0.0329) in the total population. The results suggest that the UQCC gene is a candidate gene of body measurement traits in bovine reproduction and breeding, and provide data for establishing an animal model using cattle to study big animal body type.
