The calpain system is ubiquitous in cells, mainly comprising calpains and calpain inhibitors, and is a widespread calcium-dependent cysteine protease in organisms that is involved in many cellular processes such as muscle degradation in vivo and affects the tenderness of meat after animal slaughter. The study found 128 DEGs that probably regulated tenderness traits were selected from 16 significantly enriched GO terms by transcriptome sequencing analysis, and found that the developmental changes in the expression levels of the CAPN1 gene in the pectoral and leg muscles were significantly positively correlated ( P <0.05) with the cumulative growth values of live weight and comb weight. The developmental changes in the expression levels of the CAST gene in the pectoral and leg muscles were not significantly correlated with the cumulative growth values of live weight and comb weight. Our results helped demonstrate the potential molecular mechanisms of tenderness in chickens and provide valuable information for chicken breeding.

为探究SIMdualKc模型在南方丘陵区油茶林地的适用性,利用2 a油茶的野外实测生长季数据,率定和验证了双作物系数SIMdualKc模型在南方丘陵区油茶林地的各参数。率定后作物系数K_(cbini)=0.9,Kcbmid=0.92,K_(cbend)=0.77,土壤含水率验证结果R^(2)为0.918~0.979,MAE为0.019~0.021,RMSE为0.021~0.026,EF为0.876~0.957。通过叶面积指数数据输入方式的模拟效果比较,得出日变化叶面积指数模拟效果稍好,确定了Logistic生长函数计算得到叶面积指数的可靠性与适用性,并校准了油茶在水分胁迫条件下土壤含水率的模拟值。油茶夏梢期末以及秋梢期容易产生水分胁迫影响,2021年水分胁迫系数K的范围为[0.478,1],2022年为[0.182,1]。将水量平衡法计算得到的蒸散量作为实测值与模拟值进行比较,两者具有良好的一致性,R^(2)为0.52~0.61。研究结果可为南方丘陵地区油茶林地针对夏秋季节易发生高温干旱的自然灾害制定高效节水的灌溉制度提供理论依据。

The effects of ion screening in stellar core collapses are investigated based on a new progenitor star model. Simulation results show that ion screening slightly affects the leptons and decreases explosion energy, which is a negative factor for energy transfer supernova explosions. We also investigate the effect on type Ⅱ-supernova explosions of neutrino-nucleus elastic scattering based on the new progenitor star model. It is shown that, compared with the previously calculated results, neutrinos-nucleus elastic scattering in stellar core collapses is more severe, leading to an obvious reduction of the neutrino leakage energy loss and an increase of supernova explosion energy.

本研究旨在探究造纸废水污泥调理改性后污泥脱水的效果,采用造纸厂污泥为样本,对其基本特性进行分析,并运用Fenton氧化联合氧化钙调理方法优化污泥脱水性能。最佳调理改性条件为初始pH 3.0,Fe2+和H2O2的投加量各为30mg/gDS。调理改性后污泥的比阻(SRF)显著降低,泥饼含水率减少,且胞外聚合物(EPS)中蛋白质和多糖浓度变化明显,有机物组成发生显著改变。红外光谱分析进一步证实污泥有机物结构的变化,Fenton联合氧化钙调理能有效改善造纸污泥的脱水性能。
