  In recent years, livestock manure pollution problems have become increasingly prominent phenomenon. It has brought enormous environmental pressure to our country and also provided the technical support for effective cow dung composting and high-fiber waste treatment. The experiment adopts the biomass wood vinegar as cow dung compost additives to study before and after the changes of heavy metal as Copper and Zinc. A total of six treatments, respectively, 0.20, 0.35, 0.50, 0.65, 0.80% of wood vinegar and control group. Marked them as T1, T2, T3, T4, T5 and CK. The passivation effect of Copper was T5> CK> T4> T3> T1> T2 and the best passivation effect of Copper was to add 0.80% wood vinegar, the value was 18.78%. The passivation effect of Zinc was T2> T5> T4>T1>T3> CK and the best passivation effect of Zinc was to add 0.35% wood vinegar which was 8.25%. The passivation effect of Copper and Zinc appeared on fluctuations before and after the composting process. Meanwhile, in order to further study, to prevent “Concentrated effect”, “Chelation”, “Dilutioneffect” and environmental change common giveriseto fluctuations further occurrence during the composting process. Ensure the stability of the passivation effects, minimizing interference, trying to increase the volume of compost, expanding treatment of wood vinegar gradient and extending the composting period. To prevent the secondary factor was greater than the passivation effect of wood vinegar treatment composting. It could achieve healthy and sustainable development of agriculture and environment.

  Visible and near infrared spectroscopy was investigated to identify the varieties of rice vinegars based on back propagation neural network and least squares-support vector machine. Five varieties of rice vinegars were prepared. Partial least squares discriminant analysis was implemented for calibration and extraction of partial least squares factors. The factors were used as inputs of back propagation neural network and least squares-support vector machine. Finally, back propagation neural network and least squares-support vector machine models were achieved. The threshold value of prediction was set as ±0.1. An excellent precision and recognition ratio of 100% was achieved by both methods. Simultaneously, certain effective wavelengths were proposed by x-loading weights and regression coefficients. The performance of effective wavelengths was validated and an acceptable result was achieved. The results indicated that visible and near infrared spectroscopy could be used as a rapid and high precision method for the identification of different varieties of rice vinegars.

  Two groups of tau, 3R- and 4R-tau, are generated by alternative splicing of tau exon 10. Normal adult human brain expresses equal levels of them. Disruption of the physiological balance is a common feature of several tauopathies. Very early in their life, individuals with Down syndrome (DS) develop Alzheimer-type tau pathology, the molecular basis for which is not fully understood. Here, we demonstrate that Dyrk1A, a kinase encoded by a gene in the DS critical region, phosphorylates alternative splicing factor (ASF) at Ser-227, Ser-234, and Ser-238, driving it into nuclear speckles and preventing it from facilitating tau exon 10 inclusion. The increased dosage of Dyrk1A in DS brain due to trisomy of chromosome 21 correlates to an increase in 3R-tau level, which on abnormal hyperphosphorylation and aggregation of tau results in neurofibrillary degeneration. Imbalance of 3R- and 4R-tau in DS brain by Dyrk1A-induced dysregulation of alternative splicing factor-mediated alternative splicing of tau exon 10 represents a novel mechanism of neurofibrillary degeneration and may help explain early onset tauopathy in individuals with DS.
