An improved horizontally reversible plow design based on virtual assembly semantics and constraint

There exit model errors in the constructed Horizontally reversible plough (HRP) structure through Interference check technique (ICT). This is basically due to missing parts and geometric interference and, hence, has significantly adverse effects in improving HRP. In thispaper an improved design to refine the three dimensional (3D) model of HRP is implemented by using Virtual assembly technology(VAT). To achieve this, the authors propose a combined virtual assembly semantics and constraint for assembly planning and simulationof HRP in the commercial software, e.g., SolidWorks. First, the assembly planning of HRP was captured with a semantics-based model,including spatial position, assembly orientation, type and parameters of the semantic entities; secondly, the assembly simulation of HRPwas performed by using constraint-based VAT, e.g. component grasping, moving and releasing; finally, the obtained HRP model wasverified through ICT again. The results demonstrate that not any model error exists in the refined 3D HRP model any longer and thatsemantics and constrain based VAT can support the interactive operation more effectively and accurately than those with geometric constraints. This technique was previously used for HRP model. Based on the refined 3D HRP model, the design improvement of Remotecylinder base (RCB), an important component of HRP, will be forthcoming in a future paper.

The protein encoded by SLC27A2 gene is an isozyme of long-chain fatty-acid-coenzyme A ligase family, and it converts free long-chain fatty acids into fatty acyl-CoA esters, and thereby plays a key role in lipid biosynthesis and fatty acid degradation. In the present study, SLC27A2 located on human chromosome 15 was selected as candidate gene and we isolated and cloned partial fragments of mRNA sequence and genomic fragments of porcine SLC27A2 gene. The coding region of the gene as determined by alignments shared 90% and 82% identity with human and mouse cDNAs, respectively. Detection in LargeWhite and Meishan breeds showed that a single nucleotide polymorphism (SNP) ($A{\rightarrow}G$) existed in exon 7, which caused corresponding amino acid changed for encoding. In LargeWhite pigs it encoded for Val while in Meishan pigs it encoded for Ile, so we developed the PCR-RFLP genotype method for detection of this polymorphism. Association study in 135 $F_2$ reference family indicated that significant correlation existed between the polymorphism and growth and carcass traits.
