Whether soaking or injected by BSA, low to intermediate (≦7.58 μM) concentrations of BSA improved rooting rate of cuttings and higher (≧ 15.15 μ M) concentrations of BSA significantly decreased the rooting rate of cuttings. The effect on the rooting rate by the method of BSA injected are significant than that of BSA soaking cuttings. Both of soaked and injected cuttings with low to intermediate (≦7.58 μM) concentrations of BSA markedly increased the average number of lateral roots and the average root length. The treatment of the injection had a remarkable effect on the average number of lateral roots and average root length than that of soaking whether the low or high concentration of BSA. The magnitude of changes of the endogenous GA, ABA, ZR and IAA of the cuttings were bigger in the cuttings treated by injecting than that of soaking in each stage after cutting. This study adds the understanding that organic nitrogen effects on the cuttings root formation, growth and endogenous hormone changes. © 2016 ACM.

A new Lax pair is introduced for a perturbed Kaup-Newell equation and used to construct two series of conservation laws through a Riccati equation that a ratio of eigenfunctions satisfies. Both series of conservation laws are defined recursively, and the first two in each series are presented explicitly. © 2016 World Scientific Publishing Company.

The DFT-B3LYP method, with the basis set 6-31G, was employed to calculate the molecular geometries and electronic structures of 24 3-substituted sulfur-5-(2-hydroxyphenyl)-4H-1, 2, 4-triazole compounds. EHOMO, ELUMO, ENHOMO, ENLUMO, QC1~QC8, Qn1~Qn3, QO, QS, ΔE1, ΔE2, ΣQ were selected as quantum chemical descriptors (qc). The quantitative structure-activity relationships (QSAR) were established by using leaps-and-bounds regression analysis for the antibacterial activities (AJ: Am, Ae and As) of 13 compounds to Escherichia coli, Monilia albican and Staphylococcus aureus along with the qc. The correlation coefficients (R2) and the leave-one-out (LOO) cross validation Rcv 2 for the Ae, Am and As models were 0.930 and 0.871; 0.926 and 0.869; 0.781 and 0.572 respectively. The QSAR models have both favorable estimation stability and good prediction capability by Radj 2, F, Rcv 2, VIF, AIC, FIT tests. The results indicate that the ΔE1 and ΣQ are main factors which can affect the bioactivities of these compounds directly. The antibacterial activities of the compounds increase with the increase of the ΣQ; however the higher the ΔE1 is, the lower the AJ is. The possible mechanism has been given for the antibacterial of the triazole compounds. It is known that the suitable structural modifications of R group in triazole compounds with the strong electron- attracting one are beneficial to the antibacterial activities. According to the results (11 compounds) obtained from the structural modifications, the antibacterial activities of four modified molecules are over 100% when mass fraction is 0.01%, and it is expected to be confirmed by using biologic experiments.

The primary method of power system fault diagnosis is that the fault section estimation is demonstrated a 0-1 programming model according to the acting theory of protective relays. This paper proposed a kind improved artificial fish -swarm algorithm: binary artificial fish -swarm algorithm(BAFA) for this kind of problem. Forward speed of optimal direction between swarm-behavior and follow-behavior is analyzed and a comparative analysis is made with genetic algorithm(GA) on this basis. Results indicate that follow-behavior is superior to swarm-behavior on forward speed of optimal direction and BAFA is superior to GA on the comprehensive performance. Meanwhile, it is shown that BAFA has the fast convergence speed and better optimization ability. © (2014) Trans Tech Publications, Switzerland.

Structure of 1-mm tungsten (W) coating on copper (Cu) with the different compliant layers was designed and optimized by means of ANSYS code. Three materials of titanium, nickel-chromium-aluminum alloys, and W/Cu mixtures with a thickness of 0.5 mm were selected as the compliant layers to evaluate their effects on the interface stress between W and Cu, strain, and the surface temperature under the heat load of 5 MW/m2. Application of the compliant layers can obviously alleviate the interface stress concentration compared to the sharp interface. The maximum stress reduction of about 25% was obtained from the W/Cu-compliant layer; however, the surface temperature was increased only by 12 C. Further investigation on the W/Cu-compliant layer revealed that 0.1-0.2-mm 20-35 vol.% W was the optimum structure for 1-mm W coating, which resulted in the smallest peak stress of 299 MPa and the equivalent plastic strain of 0.01%. © 2012 ASM International.

Polybrominated dibenzofurans (PBDFs) are important toxic organic contaminants released from the combustion and Pintsch process of brominated flame retardants. The properties of PBDFs are related to their structures. The structure of polybrominated dibenzothiophenes (PBDTs) is similar to that of PBDFs. In this study, atomic characteristic values of 254 molecular structural patterns of PBDEs and PBDTs are calculated, and a new connectivity index, the path index, is obtained by applying the technique of molecule graphics. The path index is combined with five thermodynamic properties of PBDFs, including molecular total energy (ET), standard enthalpy (H0), free energy (G0), standard entropy (S0) and heat capacity at constant volume (cv 0), along with four thermodynamic properties of PBDTs, including standard enthalpy (H0), free energy (G0), standard enthalpy of formation (ΔfH0) and standard free energy of formation (ΔfG0). Nine quantitative structure-property relationship models (r2>0.995) are obtained by multiple linear regression method. The Jackknifed cross validation is used to test the stability and prediction ability of each model and good results (r2>0.995) are obtained. The relative mean deviation is 0.52% to S0. The model developed is in good agreement with the values of S0 in literature. © All Rights Reserved.

In order to improve the performance of cement mortar, using compression test, flexural strength test, splitting test, adhesion test and dynamic modulus test, the improvement effect of carboxylic styrene butadiene latex on the mechanical properties of cement mortar was explored, Research results showed that with the increases the polymer-cement ratio, the flexural strength, compressive strength, splitting strength and adhesive strength of mechanism mortar of modified cement mortar all increase, and the dynamic elastic modulus decreases. Carboxylic styrene butadiene latex enhances the flexibility and anti-deforming capability of cement mortar, thereby also improves the pavement performance. The results clarify the properties variation law of cement mortar before and after modification, this provides scientific guidance for polymer latex modified cement mortar mix design. © (2014) Trans Tech Publications, Switzerland.

This paper is concerned with the existence of positive solutions to the p-Laplacian dynamic equation (φp(u Δ(t))) ∇L+h(t)f(t,u(t),uδ(t))=0,t∈[0,T] T subject to boundary conditions u(0)-B 0(∑ i=1 m-2aiu Δ(ξi))=0,uδ(T)=0, where φp(u)=|u| p-2u with p>1. By using the fixed-point theorem due to Avery and Peterson, we prove that the boundary value problem has at least triple or arbitrary positive solutions. Our results are new for the special cases of difference equations and differential equations as well as in the general time scale setting. As an application, an example is given to illustrate the result. The interesting point in this paper is that the nonlinear term f is involved with the first-order derivative explicitly. © 2010 Elsevier Ltd.
