The lerma River Upper Basin is located between Almoloya del Rio shallow lakes and Atlacomulco Municipality in the State of Mexico;is a natural resource essential to human activities in its surroundings and serves as a source of electricity and drinking water for Mexico City. However, this river is threatened by over-exploitation of its aquifers, disappearance of many of its wellsprings and uncontrolled discharges of wastewater from all sorts. Thus, the aim of this work was to evaluate the water quality in the Upper lerma River Basin using WQI proposed by the NSF and compare these results with those obtained by the National Water Commission of Mexico (CNA). WQI was calculated using seven parameters: dissolved oxygen, pH, DOB5, temperature change, total phosphates, nitrates, and total solids obtained in four different sampling campaigns carried out in 2005, 2006 and 2012. The results showed that water quality in the Upper lerma River is bad, mainly associated with high levels of BOD5, nitrates and phosphates found. The results obtained with WQI yielded the same diagnosis that the studies carried out by the CNA, in which water quality was unacceptable. It is worth noting that there is a significant water quality deterioration in the Upper lerma River Basin with the course of the years, because in 2012 were observed the lower index values regarding 2005 and 2006, so it is imperative to implement measures to restore and preserve the water quality of this important river.

一个三级儿童保健医院中流感的住院花费及其对6～23个月婴幼儿所推荐的普通流感免疫接种成本效益分析的影响

世界核心医学期刊文摘（儿科学分册） 2006年第6期2卷 29-29页

Objective: To calculate the costs of influenza hospitalization at a tertiary care children’s hospital as the basis of a cost-benefit analysis of the new influenza vaccine recommendation for children age 6 to 23 months. Study design: We reviewed the medical records of all patients admitted to Children’s Memorial Hospital (CMH) in 2002 diagnosed with influenza. Total hospital costs were obtained from the Business Development Office. Results: Thirty-five charts were analyzed. Both of the 2 patients requiring mechanical ventilation and 4 of 6 patients admitted to the intensive care unit had high-risk underlying medical conditions. Nine children were age 6 to 23 months; 4 of these 9 had no preexisting medical conditions. Had all 18 high-risk children over age 6 months been protected from influenza, approximately ＄350,000 in hospital charges could have been saved. Conclusions: Preventing the additional 4 hospitalizations in the otherwise low-risk children age 6 to 23 months for whom vaccine is currently recommended would have cost approximately ＄281,000 (＄46child) more than the hospital charges saved. When all children age 6 to 23 months are considered, influenza vaccination is less costly than other prophylactic measures. Addition of indirect costs, deaths, outpatient costs, and the cost of secondary cases would favor the cost:benefit ratio for influenza vaccination of all children age 6 to 23 months.

当今世界正迈入数字时代,大数据、云计算、"互联网+"等技术和发展理念已渗透到企业创新活动中。高技术企业作为创新主体,其协同创新的推进已经越来越受到企业间数字鸿沟的阻碍。从网络建设、网络环境、网络利用、网络人才4个维度构建了一套测度指标体系,运用问卷调查法获取数据,定量测度了高技术企业间数字鸿沟。在此基础上,采用结构方程模型分析了企业间数字鸿沟对协同创新的影响途径。结果表明,数字鸿沟可以通过管理方式、战略目标、合作投入、团队分工、学习-吸收能力5条途径影响高技术企业间的协同创新。其中最主要的影响途径是管理方式,其次是战略目标,然后才是合作投入、团队分工、学习-吸收能力。

Mulliken, NPA, MK and CHelpG population analyses have been accomplished at the level of MP2/6-31G（d,p） for the title system. The variations of four kinds of charges on NH3 with intermolecular distance infer that electron transfers from NH3 to H2O. MK and CHelpG population analyses indicate more electron transfer than Mulliken and NPA ones. The atomic charges resulted from MK and CHelpG schemes infer that electron transfers from N in NH3 to H in H2O, which confirms that this bimolecular complex possesses linear structure as H3N…HOH.
