1Clinical significance of immunohistochemica study of P53 protein in colorectal carcinoma显示文摘AIMS To determine the clinical significance of P53 protein ex-pression in colorectal carcinoma.METHODS The expression of P53 protein in 92 colorectal car-cinomas was examined using the monoclonal antibody PAb 1801.Correlation between P53 protein expression and prognosis in col-orectal carcinoma was analyzed using log-rank test.RESULTS The frequency of P53 protein expression was 57.61%,corresponding with Dukes’ staging.Analysis of survivordata demonstrated that the survival rate of colorectal carcinomawith positive P53 protein group was lower than that of negativeP53 protein group.CONCLUSIONS We conclude that the expression of P53 pro-tein is correlated with poor prognosis in colorectal carcinoma.CHEN Da-Wei WANG Yuan-He CHEN Xue-Yun WANG Qiang GAO Han Dr.CHEN Da-Wei, Surgeon-in-Charge,Having 12 papers published.Department of General Surgery,Changzheng Hospital,Second Military Medical University,415 Feng Yang Road,Shanghai 200003 China.Correspondence to Dr.CHEN Da-Wei. 1996World Journal of Gastroenterology1996,2,1:3
2The Farmer Entrepreneurs' Social Capital and Opportunity Recognition Behavior显示文摘Using the multivariate ordered logistic and probit regression method,based on the survey data of entrepreneurship concerning farmers in China,we analyze the impact of social capital ( namely the social network) on the farmers' recognition of entrepreneurial opportunities and property of entrepreneurial opportunities. The research results show that the scale of farmers being embedded in social network has a positive effect on the probability of farmers to recognize entrepreneurial opportunities. The higher the frequency of contact and the greater the size of weak ties network in the social network,then the greater the possibility of farmers to find innovative opportunities. But strong ties network has no significant effect on replicating-type entrepreneurial opportunities. At the same time,the entrepreneurial farmers' education experience, migrant worker experience,innovation capability,and deep entrepreneurial atmosphere,are all important factors affecting the farmers' opportunity recognitionJing GAO Yingliang ZHANG Changzheng HE 2013Asian Agricultural Research2013,5,3:2

6Photocatalytic fuel cell for simultaneous antibiotic wastewater treatment and electricity production by anatase TiO_(2) nanoparticles anchored on Ni foam显示文摘Photocatalytic fuel cell (PFC) holds great potential for the sustainable production of electricity and degradation of organic pollutants for solving global energy and environmental problems.However,the efficient photodegradation of organic dyes and antibiotic drugs,such as ciprofloxacin (CIP) and methylene blue(MB),remains challenging.Aiming at improving the separation efficiency of hole and electron for electricity generation in the PFC system,TiO_(2)-NPs@NF-x photoanode was fabricated by a cost-effective and laborsaving hydrothermal approach.The as-fabricated photoanode demonstrated abundant active sites,enhanced light harvesting capacity and photogenerated charge carrier separation.At a CIP-HCl concentration of 10 mg/L and p H value of about 7,85%of CIP-HCl can be efficiently removed after 3 h irradiation by 300 W Xe lamp.TiO_(2)-NPs@NF-20 photoelectrode based PFC system exhibited an impressed ability to simultaneously degrade ciprofloxacin and generate electricity under light irradiation with an open circuit voltage of 1.021 V,short circuit current density and maximum power density of 2.4 mA/cm^(2),0.357 mW/cm^(2),respectively.This work provided a cost-effective method for the treatment of organic waste and generation of electrical power.Jinhan Li Xicheng Li Shaobin Yu Shuai Gao Yang Zhang Yan Li Changzheng Wang Qiang Wang 2023Chinese Chemical Letters2023,34,2:0
7Electromagnetic interference and shielding of valve hall in HVDC converter station显示文摘The electromagnetic interference(EMI)from the valve hall as an important consideration in the design of high voltage direct current(HVDC)converter stations is analyzed by electromagnetic field numerical method and measurements.By using moment method,the EMI filed strength level as well as radio interference level(RIL)of the valve hall during the normal operation are computed after an antenna model is built for the valve tower.According to the character of EMI obtained,the practical shielding measures for valve hall are discussed to satisfy the relative standards.The test results for the500 kV converter station show that both the numerical method and shielding technique used in this paper are practical.Changzheng GAO Lin LI Zhibin ZHAO Yang LIU 2010Frontiers of Electrical and Electronic Engineering in China2010,5,1:0
8Evaluating the Derivative Value of Smart Grid Investment under Dual Carbon Target: A Hybrid Multi-Criteria Decision-Making Analysis显示文摘With the goal of“carbon peaking and carbon neutralization”,it is an inevitable trend for investing smart grid to promote the large-scale grid connection of renewable energy.Smart grid investment has a significant driving effect(derivative value),and evaluating this value can help to more accurately grasp the external effects of smart grid investment and support the realization of industrial linkage value with power grid investment as the core.Therefore,by analyzing the characterization of the derivative value of smart grid driven by investment,this paper constructs the evaluation index system of the derivative value of smart grid investment including 11 indicators.Then,the hybrid evaluation model of the derivative value of smart grid investment is developed based on anti-entropy weight(AEW),level based weight assessment(LBWA),and measurement alternatives and ranking according to the compromise solution(MARCOS)techniques.The results of case analysis show that for SG investment,the value of sustainable development can better reflect its derivative value,and when smart grid performs poorly in promoting renewable energy consumption,improving primary energy efficiency,and improving its own fault resistance,the driving force of its investment for future sustainable development will decline significantly,making the grid investment lack derivative value.In addition,smart grid investment needs to pay attention to the economy of investment,which is an important guarantee to ensure that the power grid has sufficient and stable sources of investment funds.Finally,compared with three comparison models,the proposed hybrid multi-criteria decision-making(MCDM)model can better improve the decision-making efficiency on the premise of ensuring robustness.Na Yu Changzheng Gao Xiuna Wang Dongwei Li Weiyang You 2023Energy Engineering2023,120,12:0
