In this study, controlled-release fertilizers （CRFs） with five different nitrogen release periods were pre- pared by coating large urea particles with polyethylene （PE） membranes under various experimental conditions. The preliminary and differential solubility rates, release periods, and membrane pore sizes of the obtained CRFs were measured using water immersion, scanning electron microscopy, and mercury porosimetry. For all CRF samples, the median pore diameters of the membranes were equal to 4.5-5.3 nm and pores with sizes smaller than 10 nm accounted for 86-96% of the total pore surface area. The obtained pore diameter distributions differed for the five studied types of CRF, having release periods of 1,2, 4, 6, and 8 months. Thus, for the CRFs with a 1-month release period, the maximum pore diameter reached a magnitude of 4000 nm, while this value did not exceed 30 nm for the CRFs with a release period of 8 months. Hence, we have established a relationship between the release period of CRFs and their effective maximum pore sizes.

Imbalanced application of nitrogen(N) and phosphorus(P) fertilizers can result in reduced crop yield,low nutrient use efficiency,and high loss of nutrients and soil nitrate nitrogen(NO_3^--N) accumulation decreases when N is applied with P and/or manure;however,the effect of applications of N with P and/or manure on root growth and distribution in the soil profile is not fully *** aim of this study was to investigate the combined effects of different N and P fertilizer application rates with or without manure on maize(Zea mays L.) yield,N uptake,root growth,apparent N surplus,Olsen-P concentration,and mineral N(N_(min)) accumulation in a fluvo-aquic calcareous soil from a long-term(28-year) *** experiment comprised twelve combinations of chemical N and P fertilizers,either with or without chicken manure,as treatments in four *** yield of maize grain was 82%higher,the N uptake 100%higher,and the N_(min) accumulation 39%lower in the treatments with combined N and P in comparison to N fertilizer *** maize root length density in the 30-60 cm layer was three times greater in the treatments with N and P fertilizers than with N fertilizer *** addition increased maize yield by 50%and N uptake by 43%,and reduced N_(min)(mostly NO_3^--N) accumulation in the soil by 46%.The long-term application of manure and P fertilizer resulted in significant increases in soil Olsen-P concentration when no N fertilizer was *** application reduced the apparent N surplus for all *** results suggest that combined N and P fertilizer applications could enhance maize grain yield and nutrient uptake via stimulating root growth,leading to reduced accumulation of potentially leachable NO_3^--N in soil,and manure application was a practical way to improve degraded soils in China and the rest of the world.

The coronavirus disease 2019（COVID-19） outbreak caused by the severe acute respiratory syndrome coronavirus-2（SARS-CoV-2） developed into a global health emergency. Systemic microthrombus caused by SARS-CoV-2 infection is a common complication in patients with COVID-19. Cardiac microthrombosis as a complication of SARS-CoV-2 infection is the primary cause of cardiac injury and death in patietns with severe COVID-19. In this study, we performed single-cell sequencing analysis of the right ventricular free wall tissue from healthy donors,patients who died during the hypercoagulable period of characteristic coagulation abnormality（CAC）, and patients who died during the fibrinolytic period of CAC. We collected 61,187 cells enriched in 24 immune cell subsets and 13 cardiac-resident cell subsets. We found that in the course of SARS-CoV-2 infected heart microthrombus, MYO1EhighRASGEF1Bhighmonocyte-derived macrophages promoted hyperactivation of the immune system and initiated the extrinsic coagulation pathway by activating chemokines CCL3, CCL5. This series of events is the main cause of cardiac microthrombi following SARS-CoV-2 infection. In a SARS-CoV-2 infected heart microthrombus, excessive immune activation is accompanied by an increase in cellular iron content, which in turn promotes oxidative stress and intensifies intercellular competition. This induces cells to alter their metabolic environment, resulting in increased sugar uptake via the glycosaminoglycan synthesis pathway. In addition, high levels of reactive oxygen species generated by elevated iron levels promote increased endogenous malondialdehyde synthesis in a subpopulation of cardiac endothelial cells. This exacerbates endothelial cell dysfunction and exacerbates the coagulopathy process.

硫氰酸根（SCN^-）普遍存在于HPF脱硫废液中,其含量高达90-140 g/L,对COD、色度等指标构成影响。首先对HPF脱硫废液做预处理,即以加酸的方法脱除其中的S2O2-3,然后利用氯酸根将废水中高浓度SCN^-氧化脱除,实验通过交替向废液中加入氯酸钠和浓硫酸,维持溶液pH值在1以下,使反应停留在轻度氧化阶段以使SCN^-定向转化为沉淀,处理后SCN^-的浓度由初始的69.76 g/L降至0.67 g/L,溶液COD由初始的98 600 mg/L降至2 400 mg/L。用较少的化学试剂将硫氰酸根基本脱除,达到了化学降解的目的。

为实现小麦叶片含水量精准检测,该文提出基于主成分分析(Principal Component Analysis,PCA)和长短时记忆网络(long Short-Term Memory,LSTM)构建预测模型对小麦叶片含水量进行精准检测。试验以济麦22号小麦为研究对象,均匀划分其种植区域并灌溉不同水量以作叶片水分梯度分析;然后采集叶片图像并提取叶片R、G、B颜色特征值,运用灰度梯度共生矩阵提取均值、灰度熵、逆差距、梯度熵、混合熵、惯性、等15个纹理特征值,形状特征值提取面积、宽、伸缩率;最后基于主成分分析对提取特征值进行降维处理,并分别应用BP神经网络、支持向量机(Support Vector Machine,SVM)进行检测对比。试验证明:该模型平均绝对误差、平均绝对百分误差、均方根误差分别为0.002、0.002和0.011,均优于传统预测方法,具有良好的预测性能和泛化能力。由此表明,该方法切实可行,能够满足小麦叶片水分预测的实际需要,为后期研发智能灌溉系统提供坚实理论指导。
