Restructuring Tilth Layers Can Change the Microbial Community Structure and Affect the Occurrence of Verticillium Wilt in Cotton Field

Restructuring tilth layers(RTL)is a tillage method that exchanges the 0–20 and 20–40 cm soil layers that can be applied during cotton cultivation to increase cotton yield,eliminate weeds and alleviate severe disease,including Verticillium wilt.However,the mechanism by which RTL inhibits Verticillium wilt is unclear.Therefore,we investigated the distribution of microbial communities after rotary tillage(CK)and RTL treatments to identify the reasons for the reduction of Verticillium wilt in cotton fields subjected to RTL.Illumina high-throughput sequencing was used to sequence the bacterial and fungal genes.The disease incidence and severity of Verticillium wilt decreased by 28.57%and 42.64%,respectively,after RTL.Moreover,RTL significantly enhanced bacterial richness and evenness at 20–40 cm and-reduced the differences in fungal evenness and richness between soil depths of 0–20 and 20–40 cm.The number of Verticillium dahliae decreased,while the relative abundance of biocontrol bacteria such as Bacillus and Pseudoxanthomonas increased significantly following RTL.Overall RTL improved bacterial diversity,decreased the number of Verticillium dahliae and increased the relative abundance of biocontrol bacteria,which may have suppressed the occurrence of Verticillium wilt in cotton fields.

Grain boundary restructuring and La/Ce/Y application in Nd–Fe–B magnets

Since the 1980 s, Nd–Fe–B with largest energy product(BH)max approaching the theoretical limit has become the landmark of permanent magnetic material.The application spectrum for Nd–Fe–B continues to expand over time both in the industrial and commercial sectors, which leads to growing research interests for solving the long-standing drawbacks of Nd–Fe–B, i.e., poor corrosion resistance, low coercivity, high Dy/Tb and low La/Ce/Y consumption.Concerning the above obstacles, we aim to present the novel grain boundary restructuring(GBR) approach, from GB design, processing, to structure evolution and property evaluation with a focus on the corrosion and coercivity mechanism of the restructured 2:14:1-typed magnets.Starting with an introduction to the fundamental of GBR, two representative examples,high-electrode-potential(Pr, Nd)32.5Fe62.0Cu5.5 and low-melting-point Dy71.5Fe28.5, are given with detailed descriptions of the advantages of GBR to enhance the intrinsic anti-corrosion stability and to strengthen the coercivity at low Dy consumption.Microstructure–property correlations are established to understand the critical importance of regulating the restructured GB phase to maximize the all-round performance of the 2:14:1-typed permanent magnets.Aiming at sustainable and balanced development of rare earth(RE) industry, the proceeding section proposes new prototypes of La–Ce and Y–Ce co-substitutions with dual benefits of stabilizing the 2:14:1 tetragonal phase and strengthening the intrinsic hard magnetism.The findings of additional REFe2 intergranular phase delight that the GBR approach also opens up a new horizon of research and application to develop high-performance La/Ce/Y-rich permanent magnets with deliberately tailored GB phase.

Diagenesis and Restructuring Mechanism of Oil and Gas Reservoir in the Marine Carbonate Formation,Northeastern Sichuan:A Case Study of the Puguang Gas Reservoir

Based on the technology of balanced cross-section and physical simulation experiments associated with natural gas geochemical characteristic analyses, core and thin section observations, it has been proven that the Puguang gas reservoir has experienced two periods of diagenesis and restructuring since the Late Indo-Chinese epoch. One is the fluid transfer controlled by the tectonic movement and the other is geochemical reconstruction controlled by thermochemical sulfate reduction （TSR）. The middle Yanshan epoch was the main period that the Puguang gas reservoir experienced the geochemical reaction of TSR. TSR can recreate the fluid in the gas reservoir, which makes the gas drying index higher and carbon isotope heavier because C2＋ （ethane and heavy hydrocarbon） and 12C （carbon 12 isotope） is first consumed relative to CH4 and 13C （carbon 13 isotope）. However, the reciprocity between fluid regarding TSR （hydrocarbon, sulfureted hydrogen （H2S）, and water） and reservoir rock results in reservoir rock erosion and anhydrite alteration, which increases porosity in reservoir, thereby improving the petrophysical properties. Superimposed by later tectonic movement, the fluid in Puguang reservoir has twice experienced adjustment, one in the late Yanshan epoch to the early Himalayan epoch and the other time in late Himalayan epoch, after which Puguang gas reservoir is finally developed.

Electrochemical Surface Restructuring of Phosphorus-Doped Carbon@MoP Electrocatalysts for Hydrogen Evolution

The hydrogen evolution reaction(HER) through electrocatalysis is promising for the production of clean hydrogen fuel. However,designing the structure of catalysts,controlling their electronic properties,and manipulating their catalytic sites are a significant challenge in this field. Here,we propose an electrochemical surface restructuring strategy to design synergistically interactive phosphorus-doped carbon@MoP electrocatalysts for the HER. A simple electrochemical cycling method is developed to tune the thickness of the carbon layers that cover on MoP core,which significantly influences HER performance. Experimental investigations and theoretical calculations indicate that the inactive surface carbon layers can be removed through electrochemical cycling,leading to a close bond between the MoP and a few layers of coated graphene. The electronsdonated by the MoP core enhance the adhesion and electronegativity of the carbon layers;the negatively charged carbon layers act as an active surface. The electrochemically induced optimization of the surface/interface electronic structures in the electrocatalysts significantly promotes the HER. Using this strategy endows the catalyst with excellent activity in terms of the HER in both acidic and alkaline environments(current density of 10 mA cm^(-2) at low overpotentials,of 68 mV in 0.5 M H_(2)SO_(4) and 67 mV in 1.0 M KOH).

Hollow Villages and Rural Restructuring in Major Rural Regions of China: A Case Study of Yucheng City, Shandong Province

The agricultural land resources of China are relatively limited because of its large population.Therefore,balancing the land use for industrialization,urbanization,and food security is a big challenge.In recent years,rural hollowing in China has resulted in numerous of abandoned rural houses,and the areas with abandoned houses need to be restored into agricultural land with effective land consolidation techniques.This study used the method of benefit-cost analysis and the data collected through field surveys conducted in Yucheng City in the northwest of Shandong Province in March 2009,to examine how hollow villages (HVs) to be created and how to solve the problem.The qualitative and quantitative analyses indicate following results.1) The situation of HVs is becoming increasingly severe under rapid industrialization and urbanization in Yucheng City.2) Poor infrastructure in rural areas and incomplete urbanization are the main factors that have led to the rural hollowing in many major rural regions of China.3) In order to resolve the problem caused by HVs and increase agricultural land,reconstructing rural communities in the countryside is necessary.4) A new mechanism in the provision of compensation funds by developed regions to the villages in less-developed regions must be established.

Two-Dimensional Euler Adaptive Mesh Method on Detonation

The adaptive mesh refinement （AMR） method is applied in the 2-D Euler multi-component elasticplastic hydrodynamics code （MEPH2Y）. It is applied on detonation. Firstly, the AMR method is described, including a conservative spatial interpolation, the time integration methodology with the adapitve time increment and an adaptive computational region method. The advantage of AMR technique is exhibited by numerical examples, including the 1-D C-J detonation and the 2-D implosion ignited from a single point. Results show that AMR can promote the computational efficiency, keeping the accuracy in interesting regions.

Post-industrial Economic Restructuring and Wage Inequality in Urban China, 2003-2015: A Sectoral Perspective

Income inequality in urban China has attracted growing attention from China’s urban researchers and policy makers. Whereas many studies have interrogated the pattern and process of the income gap in Chinese cities undergoing the institutional transformation from plan to market, relatively little is known about how such unequal distribution of income is related to China’s ongoing structural transformation toward a post-industrial economy. Drawing on a decomposition methodology based on the Theil index, this study aimed to address this lacuna through an empirical investigation of China’s urban wage inequality from a sectoral perspective. Our empirical study identified the low-wage manufacturing sector and the high-wage producer services sector as the two biggest contributors to urban wage inequality in China. Urban wage inequality within the producer services was found to be caused by the spatial concentration of a disproportionate number of high-paying jobs in a few developed, high-tier city-regions on the eastern coast. Our empirical findings have important implications for the formulation of policies to address the income inequality that plagues China’s continuing urbanization.

New Perspectives on Restructuring of Old Industrial Areas in China: A Critical Review and Research Agenda

The restructuring of old industrial areas has been receiving much attention in regional development studies both in industrialized and emerging economies. Although ample Chinese-speaking studies have been published on the topic, most of them suffer from paying too little attention to dynamic multi-scalar interactions between firms, institutions, policies and places, as well as a too strong focus on individual cases. They also mostly disregard internationally recognized concepts and theories in the field. Based on these internationally recognized modern concepts, this paper therefore puts forward some potential avenues for future research on the evolution of old industrial areas in China, which should overcome existing deficits in the Chinese-speaking literature. It suggests that some evolutionary economic geography concepts such as path dependence, lock-in, path creation, relatedness, as well as multi-scalar institutional and leadership approaches have useful potentials to better understand the evolutionary processes and mechanisms of old industrial areas in China.

Optimal restructuring strategies under various dynamic factors

Corporate restructuring was identified as a new industrial force that has great impact on economic values and that therefore has become central in daily financial decision making. This article investigates the optimal restructuring strategies under different dynamic factors and their numerous impacts on firm value. The concept of quasi-leverage is introduced and valuation models are built for corporate debt and equity under imperfect market conditions. The model’s input variables include the quasi-leverage and other firm-specific parameters, the output variables include multiple corporate security values. The restruc- turing cost is formulated in the form of exponential function, which allows us to observe the sensitivity of the variation in security values. The unified model and its analytical solution developed in this research allow us to examine the continuous changes of security values by dynamically changing the coupon rates, riskless interest rate, bankruptcy cost, quasi-leverage, personal tax rate, corporate taxes rate, transaction cost, firm risk, etc., so that the solutions provide useful guidance for financing and restructuring decisions.

TEMPORAL AND SPATIAL DIFFERENCES OF THE INDUSTRIAL RESTRUCTURING OF GUANGDONG PROVINCE IN THE 1990S

This paper focuses on the temporal and spatial change of industrial structure in Guangdong Province since the 1990s. The attention is initially paid to the change of industrial structure through analyzing the structure change of the three sectors, and the change of internal structures of agriculture, industry and tertiary sector respectively. Then the spatial differences of industrial restructuring are analyzed based on the four economic regions which have been agreed in the academic field: the Zhujiang(Pearl) River Delta, northern mountain region, east and west wings. Thirdly, the reasons for the spatial differences of industrial restructuring are examined. Finally a short conclusion is drawn and some suggestions for the regional integration are put forward.

Restructuring water industry in China: towards sustainable urbanization

In its urbanization course, China is faced with a scarcity of water resources in terms of both water quantity and quality. The development of water industry is a fundamental way to alleviate water shortage. Influenced by the traditional planned economy, Chinas urban water industry has been mainly owned and run by local municipal governments. Their tight fiscal budgets have led to very inadequate investments in water industry and thus, caused a slow development of water industry. In this case, restructuring urban water industry is very important. Based on the discussion concerning the trend of demand for and supply of urban water resources, this paper explores such strategic issues as water industry organization and integrated approaches addressing water scarcity. These are followed by a discussion of introducing market mechanism for restructuring water industry.

New Restructuring Model for Chinese M&S SOEs:A Case of Executive Holding Major Capital Stock

The reform for Chinese state-owned enterprises (SOEs)during the past twenty years selected several ways which couldn't solve essential problems and improve the performance of the SOEs in China. The reason is that traditional ownership instituton wasn't changed at all,the institution reach an impasse in market system which resulted in the fact that SOEs couldn't get used to keen competition. This paper analyses an ownership restructuring case in which an executive holds major capital stock in a state textile institute restructured and therefore the state ownership was withdrawn from it completely, it expounds the rationality of the model selected and points out that the model is currently a very effective way by which M & S SOEs would withdraw from competitive business field successfully.

Decentralization,spatial disequilibrium,and restructuring of coastal tourist destination-Empirical research from Sanya,China

The objective of this article is to speculate on resort restructuring in the market-oriented reform process in China.Previous studies show that spatial disequilibrium was aggravated by decentralization,which leads to the difference in tourism policy and investment,public goods,and service;a profound analytical framework is much needed for further empirical studies.This article has reviewed the relevant studies on links between decentralization and restructuring,spatial influences of decentralization on tourism,based on which we put forward the theoretical framework of resort spatial restructuring from the view of political economy analysis,then we elaborate on and discuss it based on the example of Sanya,China.In short,the article suggests that decentralization of fiscal responsibilities and institutional power contributes to the spatial disequilibrium of tourism industrial structure,land use,public infrastructure and service facilities,and to community inequality.Interests of government,investors,and community should be comprehensively coordinated in the resort spatial restructuring process from three aspects:restructuring government,optimizing space structure,and tourism industry.Furthermore,we argue that resort restructuring in the context of Sanya requires coordination of various interest groups through four ways:restructure the government power under administrative division adjustment,optimizing spatial structure,expanding industrial space to diversified tourism products,and building resort management services organization.Finally,we discussed some policy requirements for resort sustainable development.

Industrial Restructuring and the Selection of Pillar Industries in Qinghai Province, China

Based on the data from the Qinghai Statistical Yearbook 2009, the evolution course of industrial structure and the developmental status of pillar industries is analyzed. The pillar industries in Qinghai Province are analyzed and revaluated from four aspects, which cover demand and income elasticity, location quotient, contribution rate and interrelationship between industries. Through analyzing the problems and causes of the industrial structure of Qinghai Province, we know that the output structure of the three main industries has seriously departed from the employment structure; the pillar industries mainly concentrated on the fields of resource exploitation and primary processing; the interrelationship between the industries is low; and the development between the light and heavy industries are imbalanced. With the globalization and the further implementation of national preferential policies on western development, Qinghai Province follows the following principles in the restructuring of industrial structure in order to carry out the scientific thought of development and the "Ecological province" strategy. Firstly, the restructuring of industrial structure should be guided by market and scientific and technological progress. Secondly, it should fully display the regional advantages. Thirdly, it should attach importance to the developmental status and prospect of relevant accessory industries. Fourthly, the restructuring should be helpful to the labor transfer and reemployment of rural surplus labor forces. Suggestions on the selection of pillar industries and optimization of industrial structure are put forward. Qinghai Province should accelerate the restructuring of industrial structure, strengthen the support on pillar industries and lay stress on the introduction of the capitals, technologies and talents.

Addressing the Negative Self-Concept in Posttraumatic Stress Disorder by a Three-Session Programme of Cognitive Restructuring and Imagery Modification (CRIM-PTSD): A Case Study

Background: Cognitive restructuring and imagery modification for posttraumatic stress disorder (CRIM-PTSD) is a new intervention that involves only three sessions and focuses on the self-concept. It combines cognitive restructuring of core trauma-related dysfunctional beliefs and mental imagery. The effectiveness of CRIM-PTSD has recently been demonstrated in a pilot study. Method: This article presents a step-by-step description of the administration of CRIM-PTSD in a female survivor of childhood sexual abuse (CSA) suffering from PTSD and major depressive disorder related to strong self-blame. Results: The intervention showed substantial reductions in PTSD symptoms and depression in the patient comparable to those observed in the pilot study. Conclusions: CRIM-PTSD might provide an economical tool for reducing PTSD symptoms when only a short time is available for intervention. Furthermore, this tool could be included in well-established PTSD treatments. In addition to the pilot study, a randomized controlled trial is needed to further explore the feasibility and effectiveness of this short intervention.

STRUCTURE AND RESTRUCTURING OF BEIJING-TIANJIN-HEBEI MEGALOPOLIS IN CHINA

Scott proposes to use the term global city-regions to designate the phenomena that bear some resemblance to the "world cities" firstly identified by Hall and Friedmann and Wolff, and to the "global cities" of Sassen but whose essential social logic and contextual characteristics have evolved considerably since these pioneering studies were published. In simple geographical terms, a global city-region can be refered to comprise any major metropolitan area or any contiguous set of metropolitan areas together with a surrounding hinterland of variable extent-itself a locus of scattered urban settlements-whose internal economic and political affairs are bound up in intricate ways in intensifying and far-flung extra-national relationships. Scott refers to these extra-national relationships as a symptom of "globalization". As economic motors and political actors, the global city regions have been regarded as crucial parts of development strategies in China. In the "Eleventh Five-year Plan" issued by the National Development and Reform Commission of P. R. China, the Beijing-Tianjin-Hebei Province (Jing-Jin-Ji) region, one of the typical megalopolises or global city regions in the East Coastal China is paid more attention. This paper first analyzes the regional structure of the Jing-Jin-Ji region based on data of the fifth national population census of China. And then through the changes of the population growth, the dynamic process and mechanisms of the regional restructuring in the Jing-Jin-Ji is explored and discussed.
