建立了两级双溶液除湿系统,其核心部件是采用氯化钙溶液预处理空气的第1级除湿器和采用氯化锂溶液的第2.除湿器,并利用数学模型对其除湿效果进行计算.结果表明:与采用氯化钙和氯化锂混合溶液(CELD,氯化钙与氯化锂质量比1∶1)的系统相比,双溶液除湿系统的除湿效果更佳且能量利用率更高;在温度3.°C、绝对湿度16.2.g/kg的工况下,双溶液除湿系统能够使空气的绝对湿度降至7.93.g/kg,系统的热力性能系数(COP)达到1.08;若采用太阳能驱动系统,当集热器出口的热水温度为87°C时,该系统性能最佳,COP值达到1.08;当热水温度为75°C时,基于太阳辐射的COP最高,其值为0.51.

Septic shock is a common critical condition, for which effective early fluid resuscitation is the therapeutic focus. According to the 2.08 international guidelines for management of severe sepsis and septic shock, resuscitation should achieve a central venous pressure （CVP） of 8-12.mmHg within the first 6 h. However, it is still uncertain about the sensitivity and specificity of CVP in reflecting the cardiac preload. Ultrasonography is a simple, rapid, non-invasive, and repeatable method for the measurement of sensitivity and specificity of CVP and has thus gradually attracted the increasing attention of physicians. It was reported that ultrasonography can show the inferior vena cava diameter, respiratory variability index, and blood volume in patients with sepsis or heart failure.

AIM To examine the clinical features and risk factors for adverse outcomes in chronic hepatitis B(CHB) superimposed with hepatitis E virus(HEV).METHODS This retrospective cohort study included 2.8 patients with acute HEV infection(showing clinical acute hepatitis symptomology and positivity for anti-HEV immunoglobulin M) with underlying CHB(confirmed by positivity for hepatitis B surface antigen and/or hepatitis B virus(HBV) DNA over 6 mo) who had been admitted to the Shanghai Public Health Clinical Center, which represents the regional tertiary hospital for infectious diseases in Shanghai city, china. Data for adverse outcomes were collected, and included severe liver diseases(defined as liver failure and/or acute liver decompensation) and liver-related mortality. Logistic regression modeling was performed to determine the risk factors for adverse *** The symptoms caused by superimposed acute hepatitis E(AHE) were much more severe in cirrhotic patients(n = 94) than in non-cirrhotic patients(n = 13.), as evidenced by significantly higher liver complications(77.7% vs 2..4%, P 2..3. vs 7.5%, P = 0.002.. Most of the cirrhotic patients(n = 85, 90.4%) had no prior decompensation. Among the non-cirrhotic patients, superimposed AHE caused progressively more severe diseases that corresponded with the CHB disease stages, from immune tolerant to immune reactivation phases. Few risk factors were identified in the cirrhotic patients, but risk factors for non-cirrhotic patients were found to be intermediate HBV DNA levels(OR: 5.1, P = 0.012., alcohol consumption(OR: 6.4, P = 0.02.), and underlying diabetes(OR: 7.5, P = 0.003. and kidney diseases(OR: 12.7, P = 0.005). Only 2..7% of the cirrhotic patients and 9.0% of the non-cirrhotic patients had received anti-HBV therapy previously and, in all cases, the efficacy had been suboptimal.

Objective The Nenjiang-Heihe structural belt is located in the eastern Xing＇anling Mongolian Orogenic Belt between the Songnen block and Xiang＇an block. This structural belt has long been the focus of geological scholars （Miao Laicheng et al., 2.03. Liang Chenyue et al., 2.1.; Li Chao et al., 2.1.）, which has complex geological condition, strong metamorphism and deformation and serious vegetation cover. There is a great dispute about the time limit of collage of the structural belt. In order to solve the problem, this paper reports a newly discovered Devonian orthoclase granite near Hada{2.g in Molidawa banner in the middle of this structural belt, which will provide evidence for the tectonic evolution of Nenjiang-Heihe structural and Xing＇anling Mongolian Orogenic Belt.

针对铝电解槽运行数据复杂多维、结构非线性且故障样本量相对正常运行样本量少的问题,提出了一种基于数据驱动的漏槽事故预警模型。模型采用简单经典的分类算法支持向量机,避免小样本数据带来的过拟合问题。并用交叉验证训练测试方法和麻雀搜索算法对参数寻优,提高分类器的性能。同时为了更好地挖掘铝电解运行数据中的特征信息采用核主成分分析法将数据降到8维,模型运行速度提高了65.51 s。另外在设置分类标签时结合实际情况选取了三个变化显著的特征参数作为辅助分类条件从而扩充了故障样本。最后对该漏槽事故预警模型进行性能验证,实验表明模型F1分数达到了0.995,AUC值达到了0.998。

NADP（H）-dependent glutamate dehydrogenases（GDH） in lower organisms have stronger ammonium affinity than those in higher plants. Here we report that transgenic rice overexpressing the EcGDH from Eurotium cheralieri exhibited significantly enhanced aminating activities. Hydroponic and field tests showed that nitrogen assimilation efficiency and grain yields were markedly increased in these transgenic plants, especially at the low nitrogen *** results suggest that EcGDH may have potential to be used to improve nitrogen assimilation and grain yield in rice.
