Poly[diaquabis[μ2-2,4-(dichlorophenoxy)acetato-κ2 O:O′]iron(II)]
In the title compound, [Fe(C8H5Cl2O3)2(H2O)2]n, the FeII atom is located on an inversion center. It is coordinated by four O atoms from four 2,4-dichlorophenoxyacetate ligands and two water molecules, displaying a distorted octahedral geometry. The carboxylate groups of the 2,4-dichlorophenoxyacetate ligands link the Fe atoms, forming a polymeric layered network in the bc plane. Intralayer O—H⋯O hydrogen bonds enhance the stability of the two-dimensional network
Corrosion Types of Magnesium Alloys
Magnesium (Mg) alloys are susceptible to corrosion in aggressive environments. Corrosion of Mg alloys depends greatly on their composition and microstructure (grain size, the size, shape and distribution of second phases), post-processing and media. In most cases, localized corrosion, such as pitting corrosion and filiform corrosion, generally occurs due to microgalvanic corrosion between the intermetallic compounds and their neighboring α-Mg matrix. However, open literature reported that several corrosion morphologies, that is, intergranular corrosion (IGC) and exfoliation corrosion (EFC), cannot appear on Mg alloys. In this chapter, all typical corrosion modes of Mg alloys and influencing factors are introduced, including general corrosion, galvanic corrosion, pitting corrosion, filiform corrosion, IGC, EFC, stress corrosion cracking (SCC), corrosion fatigue (CF) and so on. The focus is laid on pitting corrosion and EFC. Corrosion mechanisms of Mg alloys are also discussed
Prospects of violation in decay with polarized electron beam at STCF
Based on Monte
Carlo (MC) events produced from a longitudinally-polarized electron beam, the
sensitivity of violation of decay is studied with fast
simulation software. In addition, the decay can also be used as a process to optimize the detector
response using the interface provided by the fast simulation software. In the
future, STCF is expected to obtain 3.4 trillion events, and the
statistical sensitivity of violation of decay via process is expected to reach ~ when the electron beam polarization is 80\%
Tissue-Specific Expression of the Chicken Calpain2 Gene
We quantified chicken calpain 2 (CAPN2) expression in two Chinese chicken breeds (mountainous black-bone chicken breed [MB] and a commercial meat type chicken breed [S01]) to discern the tissue and ontogenic expression pattern and its effect on muscle metabolism. Real-time quantitative PCR assay was developed for accurate measurement of the CAPN2 mRNA expression in various tissues from chickens of different ages (0, 2, 4, 6, 8, 10, and 12 weeks). Results showed that the breast muscle and leg muscle tissues had the highest expression of CAPN2 compared to the other tissues from the same individual (P < .05). Overall, the CAPN2 mRNA level exhibited a “rise” developmental change in all tissues. The S01 chicken had a higher expression of the CAPN2 mRNA in all tissues than the MB chicken. Our results suggest that chicken CAPN2 expression may be related to chicken breeds and tissues

Near-threshold photoproduction of in two-gluon exchange model
The near-threshold photoproduction of is regarded as one golden
process to unveil the nucleon mass structure, pentaquark state involving the
charm quarks, and the poorly constrained gluon distribution of the nucleon at
large (). In this paper, we present an analysis of the current
experimental data under a two-gluon exchange model, which shows a good
consistency. Using a parameterized function form with three free parameters, we
have determined the nucleonic gluon distribution at the mass scale.
Moreover, we predict the differential cross section of the electroproduction of
as a function of the invariant mass of the final hadrons , at EicC,
as a practical application of the model and the obtained gluon distribution.
According to our estimation, thousands of events can be detected per
year on EicC near the threshold. Therefore, the relevant experimental
measurements are suggested to be carried out on EicC.Comment: 6 pages, 7 figure
catena-Poly[silver(I)-μ-acridine-9-carboxylato-κ3 N:O,O′]
In the title coordination polymer, [Ag(C14H8NO2)]n, the AgI cation is coordinated by two O atoms and one N atom from two symmetry-related acridine-9-carboxylate ligands in a distorted trigonal-planar geometry. The metal atoms are connected by the ligands to form chains running parallel to the b axis. π–π stacking interactions [centroid-to-centroid distances 3.757 (2)–3.820 (2) Å] and weak Ag⋯O interactions further link the chains to form a layer network parallel to the ab plane. The AgI cation is disordered over two positions, with refined site-occupancy factors of 0.73 (3):0.27 (3)
Identification and association of the single nucleotide polymorphisms in calpain3 (CAPN3) gene with carcass traits in chickens
<p>Abstract</p> <p>Background</p> <p>The aim of this study is to screen single nucleotide polymorphisms (SNP) of chicken <it>Calpain3 </it>(<it>CAPN3</it>) gene and to analyze the potential association between <it>CAPN3 </it>gene polymorphisms and carcass traits in chickens. We screened <it>CAPN3 </it>single nucleotide polymorphisms (SNP) in 307 meat-type quality chicken from 5 commercial pure lines (S01, S02, S03, S05, and D99) and 4 native breeds from Guangdong Province (Huiyang Huxu chicken and Qingyuan Ma chicken) and Sichuan Province (Caoke chicken and Shandi Black-bone chicken), China.</p> <p>Results</p> <p>Two SNPs (11818T>A and 12814T>G) were detected by single strand conformation polymorphism (SSCP) method and were verified by DNA sequencing. Association analysis showed that the 12814T>G genotypes were significantly associated with body weight (BW), carcass weight (CW), breast muscle weight (BMW), and leg muscle weight (LMW). Haplotypes constructed on the two SNPs (H1, TG; H2, TT; H3, AG; and H4, AT) were associated with BW, CW (<it>P </it>< 0.05), eviscerated percentage (EP), semi-eviscerated percentage (SEP), breast muscle percentage (BMP), and leg muscle percentage (LMP) (<it>P </it>< 0.01). Diplotype H1H2 was dominant for BW, CW, and LMP, and H2H2 was dominant for EP, SEP, and BMP.</p> <p>Conclusion</p> <p>We speculated that the <it>CAPN3 </it>gene was a major gene affecting chicken muscle growth and carcass traits or it was linked with the major gene(s). Diplotypes H1H2 and H2H2 might be advantageous for carcass traits.</p
