Synthesis and Electronic Properties of 6-Chloro-2-diethylaminoethyl-3(2H)-pyridazinone

6-Chloro-2-diethylaminoethyl-3(2H)-pyridazinone was synthesized by the reaction of 6-chloro-3 (2H)-pyridazinone and 2-diethylamionethyl chloride reaction in methylbenzene. Then the structure was characterized by means of ~1H NMR, IR, UV. By the method of ab initio HF and density functional theory (DFT) B3LYP, the geometric structures of the reagent intermediate, the product and its isomer were optimized and their total energies were calculated. The properties for the frontier molecular orbitals and the rules for energy distribution were analyzed systematically. It was shown that the energy of the nitrogen alkyl compound is lower than that of the oxy alkyl compound and the former is stable than the latter . This result is in accordance with the fact that 6-chloro-2-diethylaminoethyl-3 (2H)-pyridazinone is synthesized by the reaction of 6-chloride-2-diethylaminoethyl-3(2H)-pyridazinone and 2-diethylaminoethyl chloride.
RAPD analysis of alfalfa DNA mutation via N~+ implantation

Germination capacity of alfalfa seeds under low energy N~+ implantation manifests oscillations going down with dose strength. From analyzing alfalfa genome DNA under low energy N~+ implantation by RAPD (Random Amplified Polymorphous DNA), it is recommended that 30 polymorphic DNA fragments be amplified with 8 primers in total 100 primers, and fluorescence intensity of the identical DNA fragments amplified by RAPD is different between CK and treatments. Number of different polymorphic DNA fragments between treatment and CK via N~+ implantation manifests going up with dose strength.

Superconducting TF and PF coils have been measured in SULTAN test facility. Segregated copper strands are included in four NbTi CICC and this is a technical innovation. Two AC losses measurement methods, calorimetric and electromagnetic methods, have been used in the experiments, and a broad frequency range (from 0.05 Hz to 6 Hz) is covered in sample test. The purpose of this experiment was to investigate AC losses of TF and PF CICC conductor including segregated copper and to check the design of PF and TF CICC coated with different resistive barriers (Pb-30Sn-2Sb and Ni plating on NbTi strands).
Preparation of novel polyethylene-graft-poly (4-vinylpyridine)-supported metallocene catalysts for ethylene polymerization

Polyethylene (PE) grafting 4-vinylpyridine copolymers has been produced as powders of different rushes by the irradiation method. After treatment with methylaluminoxane (MAO), the copolymers were used as supports for Cp_2ZrCl_2 catalyst, Results of X-ray photoelectron spectroscopy, Fourier transforms infrared spectroscopy, ultraviolet spectroscopy and scanning electron microscope measurements show that the catalytic sites have been linked through MAO on the PE-gra/f-4-vinylpyridine (PEVP), The percentages of grafting 4-vinylpyridine and supported Cp_2ZrCl_2 depend on the size of polyethylene powder. The smaller the polyethylene powder, the more percent of 4-vinylpyridine groups and Cp_2ZrCl_2 exist on the polyethylene chains, and the PEVP-supported catalyst has a relatively high activity for ethylene polymerization.
NOVEL POLYPYRROLE MICROSTRUCTURES GENERATED BY DIRECT ELECTROCHEMICAL OXIDATION OF PYRROLE ON p-TYPE SILICON SUBSTRATE

Polypyrrole microstructrues with morphology like bowls, cups, goblets and bottles have been electrochemically generated by direct oxidation of pyrrole on p-silicon substrate in the aqueous solution of camphorsulfonic acid. The well-ordered microstructures can stand upright on the working electrode surface and their morphological features can be easily controlled by changing the electrochemical polymerization conditions. The growing process of microstructures was studied by scanning electron microscopy. The microstructures made of polypyrrole films in doped state were characterized by Raman and Infrared spectra.
Induction of mitochondrion-mediated apoptosis of CHO cells by tripchlorolide

Tripchlorolide (TC) is a potent antitumor reagent purified from a Chinese herb Tripterygium Wilfordii Hook, f.. However, its cellular effects and mechanism of action are unknown. We showed here that TC induced apoptosis of Chinese Hamster Ovary (CHO) cells in time- and dose-dependent manners. TC resulted in the degradation of Bcl-2, the translocation of Bax from the eytosol to mitochondria, and the release of cytochrome c from mitochondria. Stable overexpression of human Bcl-2 could reduce the apoptosis of TC-freated cells by blocking the translocation of Bax and the release of cytoehroine c. These results indicate that TC induces apoptosis of CHO cell by activating the mitochondrion-mediated apoptotic pathway involving the proteins of Bcl-2 family and cytochrome c.

Major and trace element in seven different kinds of milk powder were studied. The concentration of 24 elements were determined by ICP-OES method, from these elements 9 elements determined by INAA. The determination of trace element contents of foodstuffs, especially milk us daily drink for all peoples age which being a complex food has great importance. The elemental analysis of milk is important both as an indicator of environmental contamination and because milk is a significant pathway for toxic metal intake and a source of essential nutrients for humans. The major elements are Ca, K, Mg, Na, P and S. While trace element are B, Ba, Co, Cr, Cu, Ke, Li, Mn, Mo, Ni, Sb, Se, Sn, Sr, V, W and Zii. ICP-OES technique is shown to lie a powerful tool for trace determinations in powder samples. This is shown by its use for analysis of a series of the milk powders mentioned and comparative results of other direct technique such as instrumental neutron activation analysis. Analysis of both standard reference material A-11 milk powder and NBS Orchard leaves for quality accurance had been completed, and used for a relative method calculate. The importance of the major and trace elements to human health was discussed.

Kinetics of thymocyte developmental process in fetal and neonatal mice

Kinetics of thymocyte development in vivo during embryogenesis was pursued. The early development of thymocyt.es in the fetal and neonatal BALB/c mice was discontinuous, with four waves of cell proliferation occurring at fetal day (Fd) 14 to 17, Fd 18 to day (D) 1 after birth, D 2 to D 5 and D6 thereafter. The fii-Kt three proliferation waves coincided with the generation of CD4~(hi)CD8~(hi) (DP), TCR~+CD4~(hi)CD8~(-/lo) (CD4 SP), and TCR~+CD4~(-/lo)CD8~(int/hi) (CDS SP) thymocytes, respectively. The transition from DN to DP cells was further investigated and it was found out that there were two differential pathways via im-mature single positive (ISP) cells in the BALB/c mice, each functioning at different fetal ages. One is via TCR~-CD4~+CD8~- cells, occurring between Fd 15 and Fd 17 and the other is via TCR~-CD4~+CD8~- cells, occurring from. Fd 17 until birth. In contrast, the TCR~-CD4~-CD8~+ pathway dominated overwhelmingly in the C57BL/6 mice. These findings shed new light on the hypothesis that the differential pathway pref-erence varies with mouse strains. With respect to the shift in the intensity of CD4 and CD8 expression on thymocytes from fetal to adult mice, the TCR~+CD4~(hi)CD8~(-/lo), and TCR~+CD4~(-/lo)CD8~(int/hi) subsets might be equivalent to the medullary type TCR~+CD4/CD8 SP cells.
Effects of N Forms and Rates on Vegetable Growth and Nitrate Accumulation

Experiments were curried out on a vegetable field with Peking cabbage (Brassica pekinensis (Lour.) Rupr.), cabbage {Brassica chijiensis var. oleifera Makino and nemoto), green cabbage (Brassica chinensis L.), spinach (Spinacia oleracea L.) and rape (Brassica campestris L.) to study the effects of N forms and N rates on their growth and nitrate accumulation. The results indicated Unit application of ammonium chloride, ammonium nitrate, sodium nitrate and urea significantly increased the yields and nitrate concentrations of Peking cabbage and spinach. Although no significant difference was found in the yields after application of the 4 N forms, nitrate N increased nitrate accumulation in vegetables much more than ammonium N. The vegetable yields were not increased continuously with N rate increase, and oversupply of N reduced the plant growth, leading to a yield decline. This trend was also true for nitrate concentrations in some vegetables and at some sampling times. However, as a whole, the nitrate concentrations in vegetables were positively correlated with N rates. Thus, addition of N fertilizer to soil was the major cause for increases in nitrate concentrations in vegetables. Nitrate concentrations were much higher in roots, stems and petioles than in blades at any N rate.
Effect of Different Amendments on Ryegrass Growth in Copper Mine Tailings

Montmoiillonite, rice straw, organic manure and chemical fertilizer were used as amendment materials for copper mine tailings, and their ell'ecis on mine tailing pli, nutrients and metal availability to ryegrass were investigated. Chemical fertilization was the most effective one in improving ryegrass growth in mine tailings among the amendment materials examined. It was found that montmorillonite raised biomass of ryegrass at the 1st and 2nd cuts, but it did not give further positive effects at the 3rd and 4th cuts. The effect of organic, materials on ryegrass growth was not so good as expected, mainly due to their slow decomposition in mini; tailings with less soil microorganisms. Available Cu and Zu contents in mine tailings decreased in the presence of montmorillonite but increased when rice straw and organic manure were used as amendments. Cu and Zn contents in ryegrass decreased with increasing the rate of montmorillonite application but increased with the rate of rice straw. Zn showed much stronger mobility from soil to ryegrass than Cu, and almost all the available N and P in mine tailings, except for the treatments with organic manure, were completely consumed after ryegrass had grown in mine tailings for more than four months and been harvested for four times. Owing to its large biomass and high metal uptake, ryegrass is a potential plant for remediation of metal contaminated soils in practice.
Effect of Electron Itineracy on Magnetism of S = 1/2 Ferromagnetic Ising Model

The effect of electron itineracy on the magnetism of S=l/2 Ferromagnetic Ising model is investigated by introducing a hopping term. The electron Green's function method is used to deal with this Hamiltonian. Hew emphasis is made on that the magnetization is caused by the difference between the filling of spin-up and spin-down electrons. This concept is in accordance with that, of band structure theory. In the zero band width limit, our results are the smut: as obtained by spin Green's function method. However, our method achieves more detailed physical information. The spontaneous magnetization, Curie temperature, total energy, and specific heat arc calculated and investigated in detail by the densities of states. Hopping term depresses the Curie temperature but remains the order-disorder transformation still to be second order transition. Above the transition point, the energy band is the same as that of tight binding system because exchange interaction has no effect anymore. While under the transition point, the energy band splits -into two subbands due to exchange interaction.
Soil Macropore Structure Characterized by X-Ray Computed Tomography

Undisturbed soil core with many inacropores and disturbed soil core with only one macropore (diameter is 10 mm) were probed by x-ray computed tomography (CT). The size, number, shape and continuity of macropores in the transverse and vertical sections of soil were characterized using CT scanning images. The probability densities of inacropores in the transverse section of soil core exhibited a logarithmic F distribution. Results indicated that CT scanning was a promising nondestructive method for characterizing macropores in soils.
Assessment of the environmental impact of artificial effluent lagoon in Jiayuguan City of China

An artificial effluent lagoon for storing wastewater were excavated in Jiayuguan City since 1994. As a part of a demonstration project of Sino-Australia cooperation, an assessment of the environmental impact of the lagoon was carried out. The assessment was based on field and laboratory tests and predictive model. The main impacts from the lagoon site are likely to be on the groundwater system, and, to a lesser extent, on ambient air quality in the vicinity. Currently it is expected that ground water is being polluted with effluent from the effluent lagoon. Air pollution(odor nuisance) is mainly caused by untreated effluent in the irrigation channel. The impact of high total dissolved salt(TDS) on groundwater is likely to be significant in the long run if the lagoon is continuously used. There is, consequently, no likelihood of contamination of surface water system, particularly of the city water supply system, from infiltration of effluent at the lagoon.
Inter-contact force analysis of impacted disk assembly by dynamic caustics

The caustic method was utilized to study the contact force transmission, in disk assemblies under impact load. The mapping equations were obtained based on the first invariant of the stress components in the disk subject to a normal concentrated force, and a characteristic dimension of the maximum size in the caustic curve was proposed to evaluate the contact force between the disks. Transient patterns of the caustic shadows were recorded by means of a high-speed camera of off-focus imaging, then the histories of the inter-contact forces among the disks were obtained with respect to the conditions of different masses and heights of the falling hammers. The influence of the impact loading and impulsive velocity was analyzed with respect to the force responses of the disk assembly, the double-peak phenomenon with comparison to the initial masses, and the energy dissipation of the systems under impact of different momenturns.

Response analysis of randomly excited nonlinear systems with symmetric weighting preisach hysteresis

An approximate method for analyzing the response of nonlinear systems with the Preisach hysteresis of the non-local memory under a stationary Gaussian excitation is presented based on the covariance and switching probability analysis. The covariance matrix equation of the Preisach hysteretic system response is derived. The cross correlation function of the Preisach hysteretic force and response in the covariance equation is evaluated by the switching probability analysis and the Gaussian approximation to the response process. Then an explicit expression of the correlation function is given for the case of symmetric Preisach weighting functions. The numerical result obtained is in good agreement with that from the digital simulation.

Utilization of river water may diminish the drought and flood risks. The scheme is beneficial to solve the problems of water resources shortage, groundwater declines and saltwater intrusion in the watershed. The object of the WPLE scheme is to achieve a sustainable integrated development of environment, ecology, economy and society. A kind of physically beautiful and functionally vivid landscape may exert its synthetical function on the diversity of landscape and the enjoyment of inhabitants. Feasibility of the scheme will be demonstrated by more experiments and tests, as well as observations in a long term.
A New Shape-Coding Algorithm by Using Wavelet Transform

In this paper, we propose a new shape-coding algorithm called wavelet-based shape coding (WBSC) . Performing wavelet transform on the orientation of original planar curve gives the corners called corner-1 points and end of arcs that belong to the original curve. Each arc is represented by a broken line and the corners called corner-2 points of the broken line are extracted. A polygonal approximation of a contour is an ordered list of corner-1 points, ends of arcs and corner-2 points which are extracted by using the above algorithm. All of the points are called polygonal vertices which will be compressed by our adaptive arithmetic encoding. Experimental results show that our method reduces code bits by about 26% compared with the context-based arithmetic encoding (CAE) of MPEG-4, and the subjective quality of the reconstructed shape is better than that of CAE at the same Dn.

Spectroscopic study on variations in illite surface properties after acid-base titration

Fl-IR, Raman microscopy, XRD,~(29)Si and ~(27)Al MAS NMR, were used to investigate changes in surface properties of a natural illite sample after acid-base potentiometric titration. The characteristic XRD lines indicated the presence of surface Al-Si complexes, preferable to Al (OH)_3 precipitates. In the microscopic Hainan spectra, the vibration peaks of Si-0 and Al-0 bonds diminished as a result of treatment with acid, then increased alter hydroxide back titration. The varied ratio of signal intensity between ~(lv)Al and ~(vl)Al species in ~(27)Al MAS NMR spectra, together with the stable BET surface area after acidimetric titration, suggested that edge faces and basal planes in the layer structure of illite participated in dissolution of structural components, The combined speclroscopic evidence demonstrated that the reactions between illite surfaces and acid-leaching silicic acid and aluminum ions should be considered in the model description of surface acid-base properties of the aqueous illite.
Probabilistic Teleportation of One-Particle State of S-level

A scheme for probabilistically teleporting an unknown one-particle state of S-level by a group of pairs of partially entangled 2-level particle state is proposed. In this scheme unitary transformation and local measurement take the place of Bell state measurement, then proper unitary transformation and the measurement on an auxiliary qubit with the aid of classical communication are performed. In this way the unknown one-particle state of S-level can be transferred onto a group of remote 2-level particles with certain probability. Furthermore, the receiver can recover the initial signal state on an S-level particle at his hand.
Theoretical and Experimental Studies on Interactions of Cationic-Anionic Surfactants

Typical cationic and anionic surfactants were chosen and their interactions were calculated by quantum chemical method. Interaction energies are -0.2378 kJ·mol~(-1), -3.3394 kj·mol~(-1) and 0.1204 kJ·mol~(-1) for the molec-ular pairs with fluocarbon and hydrocarbon chain: C_4H_(10)/C_5H_(12), C_4F_(10)/C_5H_(12), and C_4F_(10) /C_5F_(12), respectively. When hydrophilic group with cationic and anionicions is introduced, interaction energies are -287.40 kJ mol~(-1), -311.18 kJ·mol~(-1 and -345.83 kJ·mol~(-1). The results show that there is strong static interaction, between cationic and anionic surfactants. It has been predicted that mixed monolayer may be formed and surface activity is en-hanced favorably, especially for mixtures of cationic and anionic surfactants with fluocarbon and hydrocarbon chains. The anionic surfactants, sodium octadecylbenzenesulfonate perfluopolyetherbenzenesulonate(ANF-I) was synthesized, mixture effects of ANF-I with sodium octadecylbenzenesulfonate or dodecyldimethyl benzylammonium bromide were studied. The results indicate that the efficiency of mixing increased and the theoretical prediction was testified. These results can provide useful information for the design of new surfactants.
Adsorption and correlation with their thermodynamic properties of triazine herbicides on soils

Adsorption of atrazine, prometryne and prometon was determined on six soils with different physical and chemical properties. The adsorption isotherms of three herbicides could well fit Freundlich equation. On all of six soils, adsorption of herbicides increased in the order: atrazine ≈ prometon < promelrync. This order is quite the same to the calculation result of by means of excess thermodynamic properties of triazine. The Freundlich adsorption constants, K_f, showed to have good correlation with organic matter(OM% ) of soils for each of these herbicides, suggesting that DM is the main factor, which dominates in the adsorption process of these triazine herbicides.
FL-FN-MOGA Based Traffic Signal Control

In this paper, a traffic signal control method based on fuzzy logic (FL), fuzzy-neuro (FN) and multi-objective genetic algorithms (MOGA) for an isolated four-approach intersection with through and left-turning movements is presented. This method has an adaptive signal timing ability, and can make adjustments to signal timing in response to observed changes. The "urgency degree" term, which can describe the different user's demand for green time is used in decision-making by which strategy of signal timing can be determined. Using a fuzzy logic controller, we can determine whether to extend or terminate the current signal phase and select the sequences of phases. In this paper, a method based on fuzzy-neuro can be used to predict traffic parameters used in fuzzy logic controller. The feasibility of using a multi-objective genetic algorithm (MOGA) to find a group of optimizing sets of parameters for fuzzy logic controller depending on different objects is also demonstrated. Simulation results show that the proposed methed is effecfive to adjust the signal timing in response to changing traffic conditions on a real-time basis, and the controller can produce lower vehicle delays and percentage of stopped vehicles than a traffic-actuated controller.
