Catalytic performances of Ni/mesoporous SiO_2 catalysts for dry reforming of methane to hydrogen

Several mesoporous silicas with different morphologies were controllably prepared by sol-gel method with adjustable ratio of dual template, and they were further impregnated with aqueous solution of nickel nitrate, followed by calcination in air. The synthesized silica supports and supported nickel samples were characterized using N2-adsorption/desorption, X-ray diffraction (XRD), H2temperature-programmed reduction (H2-TPR), Scanning electron microscope (SEM), Transmission electron microscope (TEM) and thermo-gravimetric analysis (TGA-DTG) techniques. The Ni nanoparticles supported on shell-like silica are highly dispersed and yielded much narrower nickel particle-size than those on other mesoporous silica. The methane reforming with dioxide carbon reaction results showed that Ni nanoparticles supported on shell-like silica carrier exhibited the better catalytic performance and catalytic stability than those of nickel catalyst supported on other silica carrier. The thermo-gravimetric analysis on used nickel catalysts uncovered that catalyst deactivation depends on the type and nature of the coke deposited. The heterogeneous nature of the deposited coke was observed on nickel nanoparticles supported on spherical and peanut-like silica. Much narrower and lower TGA derivative peak was founded on Ni catalyst supported on the shell-like silica. © 2016 Science Press

The Supply-Side Structural Reforms——Adapting to and Leading China's New Normal

The Central Economic Working Conference proposed supplyside structural reforms which can be regarded as major innovations and necessary measures that adapt to and lead the new normal of economic development. The 13^(th) Five Year Plan is a critical period for the transformation of economic development patterns and economic restructuring, so clarifying the theoretical values and practical significances of the supply-side structural reforms, making a clear explanation of the scientific connotations and policy implications of these reforms from a scientific standpoint, and discussing concrete measures to promote the reforms against the background of the economic new normal not only has academic values but also has important practical implications. Viewed from the practical standpoint of China' s new normal and through analyzing the basic national conditions, this article proposes a roadmap for implementing the proposed reforms and points out that only by doing well in the hybrid operation of "addition, subtraction, multiplication and division", based on the framework of the "five policy pillars", an innovative path of the supply-side structural reforms with Chinese characteristics can be paved.

The Impact of Health Care Reform Initiatives on Ethical Conflict and Opportunities for Nurses to Improve Quality of Care While Enhancing Their Work Environments

Background: After more than a decade of the nursing profession contending that healthcare reform based almost exclusively on cost cutting was creating an array of serious ethical issues for nurses, healthcare organizations and other providers are now facing increasing demands primarily from payers to demonstrate improvement in both quality of care and patient experience along with continued cost reduction. Research Question: Have efforts by healthcare organizations to comply with these recently imposed requirements influenced the ethical environment faced by nurses and nurse leaders and if so, how? Materials and Methods: Data for assessing the current ethical environment was gathered with a close-ended survey mailed in October 2012 to a random sample of 3000 members of the American Organization of Nurse Executives. Results and Discussion: Statistical analysis of the data and comparison with the findings of a similar study conducted in 2000 indicated that along with five highly rated issues in the earlier study attributed largely to economic constraints imposed by healthcare organizations, the top-10 key ethical issues today included five issues primarily attributable to interprofessional conflict. Conclusion: Given the success of many ongoing efforts aimed at weakening these key sources of ethical conflict that have blocked many proposals to improve the quality of care, opportunities should arise for the nursing profession to more fully achieve its goals of improving the quality of care, safety and patient satisfaction and enhancing nurses’ work environments essential to that effort.

Steam reforming of acetic acid over Ni-Ba/Al2O3 catalysts:Impacts of barium addition on coking behaviors and formation of reaction intermediates

The influence of barium addition to a Ni/Al2O3 catalyst on the reaction intermediates formed,the activity,resistance of the catalyst to coking,and properties of the coke formed after acetic acid steam reforming were investigated in this study.The results showed the drastic effects of barium addition on the physicochemical properties and performances of the catalyst.The solid-phase reaction between alumina and BaO formed BaAl2O4,which re-constructed the alumina structure,resulting in a decrease in the specific surface area and an increase in the resistance of metallic Ni to sintering.The addition of barium was also beneficial for enhancing the catalytic activity,resulting from the changed catalytic reaction network.The in-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) study of the acetic acid steam reforming indicated that barium could effectively suppress the accumulation of the reaction intermediates of carbonyl,formate,and C=C functional groups on the catalyst surface,attributed to its relatively high ability to cause the gasification of these species.In addition,coking was considerably more significant over the Ba-Ni/Al2O3 catalyst.Moreover,the Ba-Ni/Al2O3 catalyst was more stable than the Ni/Al2O3catalyst,owing to the distinct forms of coke formed (carbon nanotube form over the Ba-Ni/Al2O3 catalyst,and the amorphous form over the Ni/Al2O3 catalyst).

Cyclical Patterns of China’s Reform and Their Implications for the New Era

After taking stock of China's four-decade reforms, this paper identifies the cyclical patterns of China's reforms, which consist of an intermediate cycle and three short cycles. The purpose of reform is to adjust the changing relations of production to changing productivity. China has adopted a gradualist approach of reform, and reform cycles have coincided with economic cycles. The cyclical changes of reform are of great significance to comprehensively deepening reforms in the new era: Downward pressures of the economy present the best window period for reform;a new cycle of reform will unveil a new economic cycle as well;the people's support is essential to pushing forward the cyclical movements of reform;and top-down design is essential to deepen reforms on all fronts.

Cost-Utility Analysis of Liraglutide in Type 2 Diabetes Patients in China after Chinese Reformation of Medical Care System

Objectives: The cost-utility analysis of Liraglutide is aimed at evaluating whether Liraglutide is cost-effective or not after Chinese reformation on medical insurance. The analysis is based on the results of clinical trial conducted in Asia. Methods: We applied a Markov model to estimate the quality-adjusted life years, medical cost and incidence of diabetes-related complications for patients receiving the Liraglutide as an add-on to the metformin treatment. Baseline characteristics were taken from a China’s study while the treatment effect is from an Asian study. The related medical cost and utility score were obtained from a local study in China. Having set 30 years’ simulations, the incremental cost-effectiveness ratio was calculated comparing with glimepiride treatment. The ratio would be compared with the willingness to pay for a quality-adjusted-life-year (QALY) which is three times of the GDP per capita in Beijing. Sensitivity analysis was also performed. Result: During a period of 30 years, the base-case analysis which takes discount rate at 3% shows that Liraglutide 1.8 mg results in an average incremental cost of CNY 82,671.49, an improvement in 0.12 QALYs and a reduction of incidence of diabetes-related complications comparing to glimepiride. The associated incremental cost-effectiveness ratio is CNY 688,929.08. Conclusion: Long-term project shows that taking Liraglutide as an add-on to the metformin treatment will lead to increasing quality-adjusted life years and reduction of incidence of diabetes-related complications. When the price of Liraglutide is reduced by 43 percent in China’s yuan, Liraglutide will be cost-effective in China from the healthcare system perspective taking three times of GDP per capita as our WTP threshold.

Solar chemical looping reforming of methane combined with isothermal H2O/CO2 splitting using ceria oxygen carrier for syngas production

The chemical looping reforming of methane through the nonstoichiometric ceria redox cycle(CeO2/CeO2-δ) has been experimentally investigated in a directly irradiated solar reactor to convert both solar energy and methane to syngas in the temperature range 900–1050 °C. Experiments were carried out with different ceria shapes via two-step redox cycling composed of endothermic partial reduction of ceria with methane and complete exothermic re-oxidation of reduced ceria with H2 O/CO2 at the same operating temperature, thereby demonstrating the capability to operate the cycle isothermally. A parametric study considering different ceria macrostructure variants(ceria packed powder, ceria packed powder mixed with inert Al2 O3 particles, and ceria reticulated porous foam) and operating parameters(methane flow-rate, reduction temperature, or sintering temperature) was conducted in order to unravel their impact on the bed-averaged oxygen non-stoichiometry(δ), syngas yield, methane conversion, and solar reactor performance. The ceria cycling stability was also experimentally investigated to demonstrate repeatable syngas production by alternating the flow between CH4 and H2 O(or CO2). A decrease in sintering temperature of the ceria foam was beneficial for increasing syngas selectivity, methane conversion,and reactor performance. Increasing both CH4 concentration and reduction temperature enhanced δ with the maximum value up to 0.41 but concomitantly favored CH4 cracking reaction. The ceria reticulated porous foam showed better performance in terms of effective heat transfer, due to volumetric absorption of concentrated solar radiation and uniform heating with lower solar power consumption, thereby promoting the solar-to-fuel energy conversion efficiency that reached up to 5.60%. The energy upgrade factor achieved during cycle was up to 1.19. Stable patterns in the δ and syngas yield for consecutive cycles with the ceria foam validated material performance stability.

Fluid interaction mechanism and diagenetic reformation of basement reservoirs in Beier Sag, Hailar Basin, China

Based on analysis of core observation, thin sections, cathodoluminescence, scanning electron microscope(SEM), etc., and geochemical testing of stable carbon and oxygen isotopes composition, element content, fluid inclusions, and formation water, the fluid interaction mechanism and diagenetic reformation of fracture-pore basement reservoirs of epimetamorphic pyroclastic rock in the Beier Sag, Hailar Basin were studied. The results show that:(1) Two suites of reservoirs were developed in the basement, the weathering section and interior section, the interior section has a good reservoir zone reaching the standard of type I reservoir.(2) The secondary pores are formed by dissolution of carbonate minerals, feldspar, and tuff etc.(3) The diagenetic fluids include atmospheric freshwater, deep magmatic hydrothermal fluid, organic acids and hydrocarbon-bearing fluids.(4) The reservoir diagenetic reformation can be divided into four stages: initial consolidation, early supergene weathering-leaching, middle structural fracture-cementation-dissolution, and late organic acid-magmatic hydrothermal superimposed dissolution. Among them, the second and fourth stages are the stages for the formation of weathering crust and interior dissolution pore-cave reservoirs, respectively.

Mesmerism, Sexuality, and Medicine：＂Karezza＂ and the Sexual Reform Movement

Within the scope of certain social and religious movements, mesmerism had a considerable impact on the Americanway of life during the last decades of 19th century. A famous example is the Christian Science of Mary Baker EddyBut also less known groups adopted mesmeric ideas and practices. The paper focuses on the concept of＂Karezza＂.It combined a specific sexual practice with religious ideas of divine love, birth control, social reform, women＇semancipation and health education. It was created by Alice Bunker Stockham （1833-1912）, an obstetrician andgynecologist from Chicago. Among other authorities, the writer Leo Tolstoy and medical psychologist HavelockEllis appreciated her approach. She was a pioneer of the sexual and marriage reform promoting practical advice foreveryday life. As a doctor, she stressed especially the disastrous consequences of a brutal sexual life destroyingbody and mind （not only of the women）. As an antidote, she propagated the ＂Karezza love＂ avoiding ejaculation ada punctual orgasm （climax） during intercourse. The leading idea was the imagery of a mesmeric ＂fluidum＂ unitingindividuals spiritually. Bunker＇s publications were translated into German. They corresponded to the Lebensreformmovement, but never became popular. Also the early sexology about 1900 ignored Bunker＇s concept as well as thesexual medicine later on. It is worthwhile to reconsider it within the context of the history of medicine, culture, andanthropology.

Three Great Reformers of the Roman Army

Rome was famous because of its strong military force and it dominate the Mediterranean Sea.However,it was facing severe shortage of soldiers for a long time during 150 BCE.This problem had enormously effect on the Roman society and political life such as the appearance of slavery in Rome and the use of violence in Rome.The reasons why Rome had shortage f soldiers were related to its own military system and political system.The three great reformers,Tiberius Gracchus,Caius Gracchus and Caius Marius tried their best to solve the problem.Gracchus brothers failed but Marius succeed.Experiences we can learn from these reforms will also be mentioned.

The Substantive Reform of Court Trials: A Transformation of Logic in the Methods of Evidence Investigation——Summary of the Reform Pilot Project in Chengdu

In the pilot project of the substantive reform of court trials,“unexpected” judgments appeared constantly because the traditional documentary investigation mode has been replaced by an investigation mode under the principle of directness and verbalism. This change in the logic of factual judgments has caused a change in the methods of evidence examination. In traditional evidence examination, evidence obtained from investigations is supposed to be genuine and reliable. In the substantive reform of court trials, it is presumed that evidence obtained from investigations cannot be fully trusted and it is easier to ascertain the facts of the case by investigating using the principles of directness, verbalism and individualized judging methods for evidence examinations. In practice, there are three main factors affecting the genuineness of evidence: the cognitive rules of testifiers, the motivation of the subjects who provide evidence, and the methods used by investigators to obtain evidence. Based on any one of these three factors, it cannot be concluded that evidence obtained from investigations is superior to evidence presented in court. The substantive court investigation is more advantageous to establishing the facts of a case than the traditional court investigation. The essential characteristics of the substantive reform of court trials are pursuing reality in essence instead of in form, and using the files of the court trials instead of the files of the investigation to avoid the evidence obtained through investigations from playing a decisive role in the adjudication thus making criminal procedures trial-centered rather than investigation-centered.

Exploration of the Way out for Education Reform Based on the Status Quo of Chinese and Foreign Education Systems

Against the backdrop of growing national strength and rapid economic development, the government has placed more emphasis on education. In recent years, remarkable achievements have been registered in terms of education in China, which lays a solid foundation for cultivating comprehensive professionally-trained personnel in the new era. However, the current education system is ridden with many setbacks and problems. This paper conducts an analysis of the specific conditions of education both at home and abroad, status quo of education in China, makes some reflections on the direction and measures of China's education reform based on the practical reality of education in China. Measures should be taken to inject personalities into the traditional, exam-oriented education system, which keeps pace with the new era. As is known to all, it's important to strike a balance between public education and non-government funded education in a scientific and reasonable manner. The overhauling of traditional education policies will pave the way for China's educational renaissance and realize the great blueprint of the Chinese dream.

Evolution of the “Zhejiang Spirit” During the Forty Years of Reform and Opening-up

The "Zhejiang spirit" refers to a theoretical summary of the group consciousness, mental state, value orientation and ideological realm, which is, as a motivating power, owned and recognized by all Zhejiang people, and carries Zhejiang peculiarities. President Xi Jinping, during his term of office in Zhejiang, launched a number of seminars and activities to seek "a Zhejiang spirit that moves with the times." Forty years of reform and opening-up, the "Zhejiang spirit" has experienced an evolution that can be summarized as three improvements: from spontaneous formation to deliberate cultivation, from something limited to eastern Zhejiang to an integrating force that spans the entire Zhejiang Province, and from a mere existence to a role that functions adequately. The "Zhejiang spirit" is extracted from the humanistic spirits shaped in all corners of Zhejiang province. It is "an instrumental ensemble played across the entire province," and represents a certain judgment and interpretation. The "Zhejiang spirit" not only describes and summarizes the past and present, but will also guide and motivate the future, and support people in their enterprising and industrious practices to move with the times.

The Evolution of China’s National Innovation System During the 40 Years of Reform and Opening Up

From the perspective of economic system transformations and scientific and technological system reforms, this paper investigates the evolution of China’s national innovation system (NIS) during the 40 years of reform and opening up. It concludes that China’s NIS has evolved from weak to strong, from a follower groping its way onto the track of independent innovation with Chinese characteristics. China’s innovation system has experienced a trajectory from “introduction and imitation of complete sets of technology” to “market for technology and imitative innovation,” to “integrated and secondary innovation” and on to “integrated, secondary, collaborative and original innovation combined.” The path of independent innovation with Chinese characteristics is a natural choice of economic, societal, and technological development in the new era.
