Seven sets of protein target sites, which occur in several gene promoters, have been analyzed. The results suggest that there is a possible mode of specific recognition of double-helical nucleic acids by proteins. This recognition mode is related to a special topological property of double-helical DNA, which is termed base spatial pattern (BSP) of DNA segment. BSP is the spatial topological property determined only by the spatial arrangement of the bases on double-helical DNA segment.

关键词： protein nucleic acids recognition base spatial pattern (BSP) target sites.

The microwave radiation method was introduced to prepare the Fe_2O_3/SO solid *** structure and properties were investigated by means of X-ray diffraction and infrared spectrum analyses as well as measurement of magnetic susceptibility and rate of esterification. The structure of the superacids prepared in microwave field can be crystalline or non-crystalline, the latter has not been reported yet in literatures. Comparing with the traditional superacid, the non-crystalline Fe2O3/SO superacid prepared in microwave field has the highest magnetic susceptibility and catalytic activity. The di-coordination of Fe2O3 and SO and the S=O bi-bond were reinforced by microwave radiation, which is favorable for increasing the acid intensity of the Fe2O3/SO catalyst

A three-year study over the Bai, Jingpo and Huayaodai communities in yunnan Province reveals that the community development is significantly influenced in various ways by such cultural factors as the concepts of development; concepts and traditions of inter-community relationships, consumption, mar- riage and gender; patterns of decision-making and production, resource and income allocation; as well as the role of information dissemination systems, religion and ritual. Based on the analysis over the interactive relevance between each factor and community development, some strategies and methods for dealing with such a cultural relevance in development projects are recommended.

Phase behavior of TXs/toluene/water microemulsion systems for solubilization absorption of toluene

引用

Journal of Environmental sciences 2010年第2期22卷 271-276页

作者： Lian Liu,Senlin Tian ,Ping Ning Faculty of Environmental science and Engineering,kunming University of science and technology,kunming 650093,china [a] Faculty of Environmental science Engineering Kunming University of Science technology Kunming 650093 China

Triton Xs （TXs） surfactants/cosurfactant/water/oil （toluene） microemulsion systems for enhancing toluene solubilization were proposed and its potential was investigated for toluene removal from gas stream. The results indicated that TX-100 was superior to other TXs surfactants in removing toluene without cosurfactant. The efficiency of cosurfactants for improving toluene solubilization capacity follows the order： amine 〉 alcohol 〉 acid. According to the factor analysis, the linear cosurfactants are better than the branched ones. The effects of hydrophile-lipophile balance （HLB）, salt （NaCl） concentration and temperature on the formation of microemulsion system were also discussed. The results suggested that the optimum value of HLB was 15, the effect of NaCl concentration on the system was inconspicuous and the lower temperature enhanced the solubilization capacity. Nonionic surfactant-based microemulsions had a significant absorption enhancement for toluene, indicated by as much as 82.72% of toluene in phase composition diagram, which will have a great prospect in air pollution treatment.

This paper presents the result and analysis of the composition of energy loss occurring in the hydro turbine. Two new types of energy losses,namely the hydraulic loss in the flow channel and the impact loss,are defined. All losses within the hydro turbine are divided into four types and the loss coefficients are defined accordingly. Expressions or characteristic descriptions of these losses as well as the calibration method of the loss coefficients are presented. Furthermore,the torque model of the hydro turbine where the inner energy loss takes place is established. The developed model has been used to calculate the power loss due to the mechanical friction generated by the units’ rotation to solve the difficulty of measurements of the mechanical friction loss in the hydro turbine. The definition of the impact loss explains the phenomenon that the loss of no-load is greater than that of the rated operation. A set of conversion coefficients are defined using the characteristic parameters at the rated operation,which are used to transform the parameters in the torque model into those that are easily measured. Therefore,the expression of the hydro turbine power is converted into a function that has the main servomotor displacement as its single variable. This makes the proposed model be convenient to use. Finally,the proposed model and methods are calibrated and verified using the measured data of a hydropower plant. Good agreement between the modeled results and the measurements indicates that the proposed model can represent the inner energy loss characteristics of the hydro turbine.

Journal of Materials science & technology 2002年第4期18卷 372-374页

作者： Heming CHENG, Tianchun HE and Jianbin XIEDepartment of Engineering Mechanics, kunming University of science and technology, kunming 650093, china Dept. of Eng. Mech. Kunming Univ. of Sci. and Technol. Kunming 650093 China

In order to simulate thermal strains, thermal stresses, residual stresses and microstructure of the steel during gas quenching by means of the numerical method, it is necessary to obtain an accurate boundary condition of temperature field. The surface heat transfer coefficient is a key parameter. The explicit finite difference method, nonlinear estimation method and the experimental relation between temperature and time during gas quenching have been used to solve the inverse problem of heat conduction. The relationship between surface temperature and surface heat transfer coefficient of a cylinder has been given. The nonlinear surface heat transfer coefficients include the coupled effects between martensitic phase transformation and temperature.

AIM: To investigate the effects of copper-aspirin complex on rat thrombosis and the interaction between plateletsand neutrophils. METHODS: The model of electrically stimulated carotid artery thrombosis in Sprague Dawleyrats was used; the effects of copper-aspirin complex on rat platelet-neutrophil adhesion and platelet aggregationstimulated by activated neutrophils were observed by rosette assay and Borns method, respectively. RESULTS:Intragastric copper-aspirin complex (5, 7, and 10 mg/kg) dose-dependently prolonged the occlusion time; it signifi-cantly decreased the rosette number formed between thrombin-activated platelets and neutrophils; the 50 % ofinhibitory concentration (IC50) was (54.64.3) mol/L. Copper-aspirin complex markedly inhibited rat plateletaggregation induced by either cell free supernatant of activated neutrophils or by activated neutrophil *** values of IC50 were (224.516.2) mol/L and (820.521.4) mol/L, whereas aspirin had no ***: Copper-aspirin complex inhibited platelet-neutrophil interactions through a different property fromaspirin and resulted in a more potent antithrombotic activity.
