Inhomogeneous Strain Behaviors of the High Strength Pipeline Girth Weld under Longitudinal Loading.

Unforeseen failures in girth welds present a significant challenge for the pipeline industry. This study utilizes 3D Digital Image Correlation (DIC) assisted cross-weld tensile testing to analyze the strain response of high-strength thick-walled pipelines, providing essential insights into the strain migration and fracture mechanisms specific to girth welds. The results reveal that the welding process significantly affects the mechanical distribution within the girth weld.

Phylogeny and Evolution of Multiple Common Carp (Cyprinus carpio L.) Populations Clarified by Phylogenetic Analysis Based on Complete Mitochondrial Genomes.

Common carp (Cyprinus carpio L.) is one of the oldest, most widely farmed commercially important freshwater fish in the world. However, many undetermined phylogenetic relationships and origins of common carp lineages remain, which are obstacles to conservation and genetic breeding of this species.

Genome sequence and genetic diversity of the common carp, Cyprinus carpio.

The common carp, Cyprinus carpio, is one of the most important cyprinid species and globally accounts for 10% of freshwater aquaculture production. Here we present a draft genome of domesticated C. carpio (strain Songpu), whose current assembly contains 52,610 protein-coding genes and approximately 92.

Transcriptome sequencing and analysis of wild Amur Ide (Leuciscus waleckii) inhabiting an extreme alkaline-saline lake reveals insights into stress adaptation.

Background: Amur ide (Leuciscus waleckii) is an economically and ecologically important species in Northern Asia. The Dali Nor population inhabiting Dali Nor Lake, a typical saline-alkaline lake in Inner Mongolia, is well-known for its adaptation to extremely high alkalinity. Genome information is needed for conservation and aquaculture purposes, as well as to gain further understanding into the genetics of stress tolerance.

The complete mitochondrial genome of Channa maculata (Perciformes: Channidae).

This paper reports the complete mitochondrial genome (mitogenome) sequence of Channa maculate (Taiwan snakehead). The mitogenome of Taiwan snakehead was determined to be 16,558 bp in length. It contains 13 typical vertebrate protein-coding genes, 22 tRNA genes, 2 rRNA genes, 1 OL (putative light-strand origin of replication), and 1 putative control region (D-loop).

Complete mitochondrial genome of Leuciscus waleckii (Cypriniformes: Cyprinidae: Leuciscus).

The next generation genome sequencing technology and traditional polymerase chain reaction method were employed to obtain the complete mitochondrial genome of Amur ide (Leuciscus waleckii) from Dalinor Lake in Inner Mongolia, China. The mitogenome of Amur ide was determined to be 16,605 bp in length. It contains 13 protein-coding genes, 2 rRNA and 22 tRNA genes.

The complete mitochondrial genome of the Oujiang color carp, Cyprinus carpio var. color (Cypriniformes, Cyprinidae).

The complete mitochondrial genome of Oujiang color carp was determined to be 16,581 bp in length accurately using the next generation sequencing technology and bioinformatics tools. The complete mitochondrial genome of Oujiang color carp shows typical circular molecule structure of vertebrate's mitochondrial genome, which consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 control region. The whole genome base composition was estimated to be 31.

[Determination of seven metal elements in Yunnan wild Schizophyllum commune Fr by atomic absorption spectrometry].

The seven metal elements in Yunnan wild schizophyllum commune Fr, including Zn, Co, Ni, Cu, Fe, Cr and Mg, were determined by atomic absorption spectrometry for providing a scientific basis of the development. The results show that Zn, Co, Ni, Fe, Cr and Mg are relatively rich in schizophyllum commune Fr and the content of Cu is lower. The ratio of the content of Zn to that of Cu is 7.
