Characteristics of water consumption by transpiration of the four garden plants in the nursery of Agricultural and Animal Husbandry College of Tibet University has been studied using the 2-year-old potted seedlings. The experiment shows that: All of the four plants had a higher water consumption by transpiration in the full light condition than in the full shade condition. The four plants had a basically same process of water consumption in the two conditions: All of them had a lower value in the morning and evening, and a peak during noon 13:00-15:00. In the full light and shade conditions, the water consumption rate of the four plants represented the same sequencing: Sorbaria sorbifolia> Rosa chinensis Jacq.> Syringa oblata Lindl> Ligustrum quihoui Carr.. In the full light condition, all four plants had the maximal water consumption rate in August and minimal water consumption rate in December. Among them, the water consumption rate of Sorbaria sorbifolia in December accounted for 79.26% that of August, and the water consumption rate of Ligustrum quihoui Carr. in December accounted for 84.22% that of August.
As the Earth continued to cool down, the chemistry of granitic rocks reflect the changing conditions &/or processes of continental crust formation. Compared to the 1.0 Ga charnockites, the 1.0 Ga charnockites in the Eastern Ghats Belt, are more potassium and Rubidium rich, with more negative Eu anomalies and show much less HREE fractionation. Thus the 1.0 Ga charnockites are more evolved in composition and this is consistent with secular evolution of the continental crust throughout the Proterozoic era.
A r u t h e n i u m c o m p l e x o f t h e 4 h y d r o x y 1,10-phenanthroline ligand was synthesized, and the variation of its absorption and emission intensity and litetime with pH characterized. Excited state lifetime, luminescence intensity, and emission properties were determined. The complex exhibits a maximum at 460nm, and a small red shift at higher pH. The spectra show a well defined isobestic point. Luminescence intensity exhibited a sigmoidal relationship with pH, a behaviour that is similar to those of other ruthenium complexes carrying protonable functional groups. This characteristic is suggestive of the suitability of this complex for pH sensor design for medical practices as well as industrial processes. pH dependence is more evident in the emission than the absorption spectra, a behaviour characteristic of higher pH dependence on the excited than the ground state of the complex. Emission lifetimes of 165.4 ns and 3.08 ns for the protonated and deprotonated states respectively, were determined and the pKa value calculated as 3.68.
Soft computing techniques are more and more widely used to solve a variety of practical problems. This paper applied the integration of different soft computing techniques in intrusion detection system(IDS). Due to the increasing incidents of network attacks, building effective intrusion detection system is necessary, but it faces great challenges. Two sorts of soft computing techniques are studied:Artificial Neural Network (ANN) and Support Vector Machines(SVM). Experimental results show that integration of ANN and SVM is superior to individual approaches for intrusion detection in terms of classification accuracy.
4-{[(E)–1H–indol–3H–ylmethylidene]amino}–1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol–3-one and its Al(III), In(III) and Tl(I) Complexes have been synthesized and characterized by physical methods and spectral studies. All the complexes were purified and their structures were elucidated using melting point, stoichiometry, molar conductivity, UV-visible, infrared, nuclear magnetic resonance and GCMS Spectral Studies The geometry around the metals were deduced based on the spectral information and were found to be five coordinate in all the complexes. The Schiff base ligand is coordinated to the metals through the participation of its imine nitrogen, indole-nitrogen and the oxygen of the antipyrine moiety. These complexes were also tested against different bacteria and fungi using Agar well diffusion method to determine their antimicrobial potency and they were found sensitive against Escherichia Coli, Pseudomonas aeruginosa, Basillus subtilis and Candida albicans but none was found active against Staphylococcus aureus.

Using Solidworks and MATLAB as solid modeling and computation tool, a cylindrical cam model with clearance is developed in this paper. The purpose of such a model is for future study of wear, such as wear pattern and wear rate. The model is based on the reported Achard wear model. It is hoped that the model not only can predict the wear rate and depth of wear, but also serve as a tool to cylindrical cam design, for less wear and longer useful life. Wear depth prediction model established in this paper shows that the wear depth will increase, if the cam rotational speed increases.

This paper discusses the problem of pricing on European options in jump-diffusion model by martingale method. We assuming jump process are more commen then Possion process a kind of nonexplosive counting process. Supposing that the dividend for each share of the security is paid continuously in time at a rate equal to a fixed fraction of the price of the security. By changing the basic assumption of R.C.Merton option pricing model to the assumption. It is established that the behavior model of the stock pricing process is jump-diffusion process. With risk-neutral martingale measure, pricing formula and put-call parity for European options with continuous dividends are obtained by stochastic analysis method. The results of Margrabe are generalized.

According to the latest statistics, the main reason of the increase of fog and haze in China lies in the increased air pollution emission caused by enlarged energy demand of the whole society every year. The pollution mainly comes from thermoelectric emissions, heavy chemical industry enterprises, automobile exhaust, residential heating in winter, living (cooking, hot water), urban construction and demolition, etc. One main reason is industrial pollution, and the pollution caused by coal-use accounts for more than 65% of the total industrial pollution. This paper aims at the useful skills of industrial coal to enable enterprises to use coal more economically and more environmentally friendly, so that enterprises can save costs, duly fulfill their social responsibilities to environmental cause and achieve economic and environmental benefits.
Protection of the environment is becoming more important role as pollution and magnetic loads from electronic devices are growing as never before. The radioactive background radiation does not explore explicit increase nevertheless more and more attention is paid to this. An increasing number of countries are paying more attention to measurements of the levels of background radiation from various radioactive sources and to the values of their exposure limits. It is known that the vast majority of background radiation in the enviroment comes from radioactive construction (buildings, roads, etc.) built by humans. It is important to understand its sources, evolution, determining parameters, etc. Radioactivity of the human-built environment is assessed on the basis of building materials, construction techniques, and dose-loading related to building technologies. The Department of General and Environmental Physics in the Juhasz Gyula Teacher Training College at the University of Szeged (Hungary) out radioactive measurements related to background radiation, especially the absorbed dose load from full gamma radiation. Among a wide range of measurements, the most important are: The power of radiation from walls and other parts of buildings. The field, such as radioactivity mapping of the environment. Using maps, we not only have actual data for the radioactivity, but we can follow the impact of the human-built environment (buildings, streets, etc.) on whole background radiation (Koteles, 1994).
Support vector machine is a new kind of learning method based on solid theoretical foundation, but this method has the characteristic of sensitivity to parameter. According to this characteristic, this paper use genetic algorithm to optimize the parameters of SVM and cross validation is introduced to reduce the dependence of the parameters on the training samples. Through the analysis of fatigue data for the relevant literature, take the parameters of the best generalization ability as the final parameters and apply the obtained model (GA-SVR) in material fatigue life prediction. Compared with the conventional SVR model and PSO-SVR model, the mean square error and the square of correlation coefficient are used to verify the reliability and accuracy of the three models. The results show that, the GA-SVR model can predict the fatigue life of materials with high accuracy.
