二氧化铈(CeO),作为一种十分重要的稀土氧化物材料,在催化、固态燃料电池、生物等领域都有着十分广泛的应用前景。我国的稀土资源储量非常丰富,占世界总储量的80%,其中铈在地壳中的丰富度占居25位。我国的CeO产品的贸易量虽然很大,可是产品的质量和精度却一直没有得到明显的提升,价格比较低廉。纳米CeO的优势主要体现在:颗粒尺寸较小、表面原子配位不全、内部Ce离子价态的变化等因素使其表面活性增强;并且随着颗粒尺寸的减小,会形成凹凸不平的原子台阶,进一步增加反应接触面积,表现出更加优异的反应活性。基于此,我们采用的超临界水热合成方法,合成单分散的立方CeO纳米晶,并系统改变表面修饰条件,合成不同暴露面的CeO纳米晶,并结合先进的球差校正扫描透射电子显微镜(AC-STEM)及电子能量损失谱(EELS)多种分析手段对其进行深入分析,探究纳米晶的生长机理[1,2]。与此同时,我们定量地研究了纳米晶中Ce离子化学价态的分布规律,结合第一性原理计算深入讨论了纳米尺寸效应、掺杂元素、晶格结构和离子化学价态之间的相互关系[3,4]。本研究聚焦CeO纳米晶体,深入讨论了CeO纳米晶表面原子结构、掺杂元素、界面化学组成及离子化学价态分布等因素对其催化性能的超微观影响机制,为开发和设计多组分、多维度、高活性的纳米晶功能材料提供可靠的理论依据和实验数据。

＜正＞The stability of reinforced soil structure is solved here based on the rigid plastic finite element method,in which two distinct constraint conditions are newly imposed upon the velocity field at limit *** is,the distance of two soil nodes along axial rigid reinforcement and the direction consisting three continuous soil nodes along flexural rigid facing are constrained not to change and bend,*** a sand slope is improved by a horizontal reinforcement,a remarkable reinforcing effect is obtained because of the high mean effective stress concentration around the *** analysis method explains well the results of model tests on sandy soil slope concerning the ultimate load,initial tangent of load-deformation curve and the tensile force distribution developed along reinforcements.

The difference in gastro-esophageal reflux disease (GERD) symptoms between elderly and younger GERD patients has not been fully studied. Our aim was to examine if there was any difference in the degree of GERD symptoms between elderly and younger patients with reflux esophagitis. Patients who were diagnosed by endoscopic examination as having reflux esophagitis and who answered the questionnaire on the frequency scale for the symptoms of GERD (FSSG) were included. Elderly and younger adult patients were defined as patients aged 65 and over or less than 65, respectively. 596 subjects were included. 184 subjects (mean 71.1 years;114 males) were classified into the Elderly group, and 412 subjects (mean 51.2 years;307 males) into the Younger group. The mean FSSG score of the Elderly and Younger groups was 6.7 and 8.4, respectively (p = 0.0024). Among those with severe esophagitis, the mean FSSG score of the Elderly and Younger groups was 8.5 and 8.7, respectively (p = 0.58). Although elderly patients tended to have less degree of GERD symptoms than younger patients, these findings suggest that there may be no significant age-related difference in complaints of GERD symptoms among severe reflux esophagitis patients.

Background: Smoking is considered to be risk factors of gastroesophageal reflux disease (GERD). The present study aimed to reveal whether quit smoking improves GERD symptoms and QOL of patients. Methods: In this prospective study, 33 patients who participated in a 12-week quit smoking program filled out the Frequency Scale for the Symptoms of GERD (FSSG) questionnaire, and SF8 QOL questionnaire. Patients filled out the questionnaires at baseline and during the program at 2 weeks, 4 weeks, 8 weeks and 12 weeks. In the FSSG, the responses were scored and the reflux score (RS), dysmotility score (DS) and total score (TS) were calculated. Results: There were 22 males and 11 females. Their mean age was 54.8 ± 13.0 (mean ± SD) yr, BMI was 22.9 ± 4.0, and duration of smoking was 33.5 ± 12.5 years. Ten patients belonged to GERD subgroup (baselineFSSGscore ≥ 8). All patients were successful at quit smoking. Scores of TS/RS/DS are 8.6 ± 1.8 (mean ± SE)/4.2 ± 0.9/4.5 ± 0.9 at baseline, 4.7 ± 1.6**/2.5 ± 0.9**/2.3 ± 0.7** at 2 w, 5.7 ± 1.3**/2.6 ± 0.6*/3.0 ± 0.7* at 4 w, 4.5 ± 1.4*/2.2 ± 0.8*/2.3 ± 0.8* at 8 w and 3.7 ± 1.2**/1.7 ± 0.6**/2.0 ± 0.7** at 12 w, respectively (**p < 0.01, *p < 0.05 vs. baseline). Among GERD subgroup, Scores of TS/RS/DS are 18.0 ± 2.9/8.9 ± 1.6/9.1 ± 1.5 at baseline, 8.8 ± 3.0/5.1 ± 1.7/3.7 ± 1.6 at 2 w, 10.8 ± 2.9/5.4 ± 1.6/5.4 ± 1.5 at 4 w, 7.6 ± 2.9*/4.1 ± 1.6/3.5 ± 1.5* at 8 w and 7.1 ± 2.9*/3.2 ± 1.6*/3.9 ± 1.5* at 12w, respectively. Regarding QOL, physical component score has significantly improved at 2, 4, 8 and 12 w and mental component score at 4w, respectively. Conclusions: Quit smoking significantly improved not only GERD symptoms but also QOL, indicating that quit smoking might be an option in the treatment strategy of GERD symptoms.

Open Journal of Modern Hydrology 2014年第2期4卷 27-43页

Glaciers from the West side of the Royal Andes are an important source of fresh water for some of the most important Bolivian cities like El Alto. Temperature is an important datum for hydrological modelling and for glacier melt estimation. All temperature measurement devices have some degree of uncertainty due to systematic errors;thus, any temperature measurement has some errors. It is important to estimate the influence of such errors on the results from hydrological models and the estimation of melt water. The present study estimates the melt water contribution from the glaciers Tuni and Huayna West as a source of water supply for human consumption of El Alto considering the errors from temperature measurements. The hydrologic response of the basins was simulated with a hydrologic model. The glacier melt contribution was estimated as the difference between the discharge from the current scenario (with glaciers) and the discharge from a scenario without glaciers. Several volumes of melt water were estimated considering the temperature measurement and its possible errors. The uncertainty of such melt water volume was addressed by performing a Monte Carlo analysis of the possible melt water. The melt water contribution from glacier Tuni and Huayna West during the hydrologic year 2011-2012 was between 1.37 × 106 m3 and 1.72 × 106 m3. Such water volume is enough to meet the yearly water demand of between 6.81% and 8.55% of El Alto.

本文叙述了一种在超临界甲苯-萘满中催化氢化处理煤沥青,以除去其中氮的新方法。所得结果表明,氮可以从原沥青中选择性地除去,由于扩散率高的缘故,反应速度比传统方法高得多,也许因为超临界流体具有高的深解本领,因而可以防止在催化剂上形成焦炭沉积。
