| 2 | SORPTION BEHAVIOR AND MECHANISM OF SAMARIUM(III) ON AMINO METHYLENE PHOSPHONIC ACID RESIN显示文摘Sm(III) was quantitatively adsorbed by amino methylene phosphonic acid resin (APAR) in the medium of pH=5.0. The statically saturated sorption capacity is 251mg/g·resin. Sm(III) adsorbed on APAR can be reductively eluted by 2.0mol/L HCl. The sorption rate constant is k298= 1.35×10-5s-1. The sorption behavior of APAR for Sm(III) obeys the Freundlich isotherm. The enthalpy change △H of sorption is 24.9kJ/mol. The apparent activation energy is Ea=11.7kJ/mol. The sorption mechanism shows that the nitrogen and oxygen atoms of the functional group of APAR coordinated with Sm(III) to form coordination bond. | Wang Yongjiang WU Xiangmei Xiong Chunhua** Department of Chemistry, Lishui Teachers College, Lishui, Zhejiang 323000 | 2001 | Chinese Journal of Reactive Polymers2001,10,2: | 5 |
| 3 | Prediction and Analysis of O3 Based on the ARIMA Model显示文摘Despite of the small amount in the atmosphere,ozone is one of the most critical atmospheric component as it protects human beings and any other life on the earth from the sun's high frequency ultraviolet radiation. In recent decades,the global ozone depletion caused by human activities is w ell know n and produces an ' ozone hole',the most direct consequence of w hich is the increase in ultraviolet radiation,w hich w ill affect human survival,climatic environment,ecological environment and other important adverse impacts. Due to the implementation of the M ontreal protocol and other agreement,the total amount of ozone depleting substance in the atmosphere has been prominent reduced,w hich w ill lead to a new round of regional climate change.Therefore,predicting the changes of the total ozone in the future w ill have an important guiding significance for predicting the future climate change and making reasonable measures to deal w ith the climate change. In this paper,based on the ozone data of 1979 to 2016 in the southern hemisphere and ARIM A model algorithm,using time series analysis,w e obtain prediction effect of ARIM A model is good by Ljung-Box Q-test and R^2,and the model can be used to predict the future ozone change. With the help of SPSS softw are,the future trend of the total ozone can be predicted in the future 50 years. Based on the above experiment results,the global ozone change in the future 50 years can be forecasted,namely the atmospheric ozone layer w ill return to its 1980's standard by the middle of this century at the global scale. | FENG Dengchao LIANG Lishui LI Chunjiao | 2017 | Instrumentation2017,4,2: | 2 |
| 4 | The Development of Top-Hat Flow Field in a Circular Symmetrical Subsonic Nozzle显示文摘In this work, the numerical analysis and experimental measurements were made to investigate the development of top-hat flow field at atmospheric pressure in a circular symmetrical subsonic nozzle. Measurements were carried out over a range of inlet velocities(about 0.07–7 m/s) based on a nozzle with constant geometric parameters, which also provided verification for the numerical simulation. The objective of this study was to determine the change of top-hat flow field from the well-known pipe velocity profile to the saddle-back distribution as well as the key behaviours for the process. Results revealed a close coupling relationship between the process and the pressure gradient inside nozzle. It was concluded that the local flow direction of fluid near the edge of cross section was changed by static pressure gradient and overlapped with the mainstream. The increase in kinetic energy of each gas particle on the cross section was different contributed to the formation of top-hat flow field. The saddle-back distribution seems to occur after the appearance of the critical position. In addition, the influence of inlet velocity on the location of critical position as well as the degree of saddle-back distribution was also concerned. | ZHANG Han JIA Li CUI Lishui LI Chunhui | 2019 | Journal of Thermal Science2019,28,5: | 2 |

| 13 | Human immunodeficiency virus type 1 tat accelerates kaposi sarcoma-associated herpesvirus kaposin A-mediated tumorigenesis of transformed fibroblasts in vitro as well as in nude and immunocompetent mice显示文摘Kaposi sarcoma-associated herpesvirus(KSHV) is necessary but not sufficient to cause Kaposi sarcoma(KS).Coinfection with human immunodeficiency virus type 1(HIV-1), in the absence of antiretroviral suppressive therapy, drastically increases the risk of KS.Previously, we identified that HIV-1 transactivative transcription protein(Tat) was an important cofactor that activated lytic cycle replication of KSHV.Here, we further investigated the potential of Tat to influence tumorigenesis induced by KSHV Kaposin A, a product of KSHV that was encoded by the open reading frame K12(a KSHV-transforming gene).By using colony formation in soft agar, H-3-TdR incorporation, cell cycle, and microarray gene expression analyses, we demonstrated that Tat enhanced proliferation as well as mitogen-activated protein kinase, signal transducer and activator of transcription 3, and phosphatidylinositol 3-kinase/protein kinase B signaling induced by Kaposin A in NIH3T3 cells.Animal experiments further demonstrated that Tat accelerated tumorigenesis by Kaposin A in athymic nu/nu mice.Cells obtained from primary tumors of nude mice succeeded inducing tumors in immunocompetent mice.These data suggest that Tat can accelerate tumorigenesis induced by Kaposin A.Our data present the first line of evidence that Tat may participate in KS pathogenesis by collaborating with Kaposin A in acquired immunodeficiency syndrome(AIDS)-related KS(AIDS-KS) patients.Our data also suggest that the model for Kaposin and Tat-mediated oncogenesis will contribute to our understanding of the pathogenesis of AIDS-KS at the molecular level and may even be important in exploring a novel therapeutic method for AIDS-KS. | Chen, Xiuying Cheng, Lin Jia, Xuemei Yao, Shuihong Lv, Zhigang Qin, Di Fang, Xin Lu, Chun Nanjing Med Univ, Dept Microbiol & Immunol, Nanjing 210029, Peoples R China.Chen, Xiuying Lu, Chun Nanjing Med Univ, Lab Reprod Med, Nanjing 210029, Peoples R China.Chen, Xiuying Lu, Chun Nanjing Med Univ, Key Lab Pathogen Biol Jiangsu Prov, Nanjing 210029, Peoples R China.Chen, Xiuying Lu, Chun Key Lab Lab Med Jiangsu Prov, Nanjing 210029, Peoples R China.Chen, Xiuying Lei, Yongliang Lishui Ctr Dis Control & Prevent, Lishui 323000, Zhejiang, Peoples R China.Cheng, Lin Huanghe Sci & Technol Coll, Dept Microbiol & Immunol, Zhengzhou 450006, Peoples R China.Zeng, Yi Youjiang Med Coll Nationalities, Dept Microbiol & Immunol, Bose 533000, Peoples R China. | 2010 | 南京医科大学学报(自然科学版)2010,30,1: | 1 |

| 16 | Triphenylamine-based highly active two-photon absorbing chromophores with push-pull systems显示文摘Two triphenylamine-based star-type push-pull chromophores(T1, T2) were designed and synthesized.Triphenylamine serves as the central core and acts as an electron-donating group surrounded by electronwithdrawing pentafluorobenzene or N,N-dimethyl substituted tetrafluorobenzene, which are connected by ethylene bridges. Single-crystal X-ray diffraction confirmed the structures and molecular arrangement of two chromophores. The systematic photophysical research of T1 and T2 absorption characteristics was carried out to gain a better understanding of how structure-property relationships affect the observed nonlinear optical absorption phenomenon. Complementary calculations based on density functional theory(DFT) further confirmed the experimental results. Both chromophores exhibited excellent two-photon absorption(TPA) properties in CH_(2)Cl_(2). Notably, T2 has more remarkable nonlinear optical absorption effects with the TPA cross-section up to 4.24 × 10~7GM. By adjusting the electronic structures of the chromophores through introducing pentafluorobenzene or N,N-dimethyl as functional groups with different electron-donating or withdrawing behaviors, the TPA performance of the small organic molecule could be greatly enhanced. These molecular structures with push-pull systems were excellent candidates for different two-photon applications. | Yanqi Ban Linhong Hao Zhenbo Peng Lishui Sun Lihua Teng Yingjie Zhao | 2023 | Chinese Chemical Letters2023,34,7: | 0 |
