Abstract:In order to study the effects of nitrogen (N), phosphorus (P) and potassium (K) on the yield, the appearance eligibility ratio and the contents of total glucosinolates and glucoraphanin of cauliflower, the 311-A optimization regression design was used to conduct field experiments of N, P, K fertilizer treatments using winter cauliflower variety "HB16". The models of the balanced application for N, P and K fertilizers were set up. According to the different production targets, the different optimal combinations of applying NPK fertilizers could be carried out. The results showed that the optimal combination of applying fertilizer was 372.83 kg/hm²N, 89.65 kg/hm² P2O5 and 201.41 kg/hm² K2O, the highest yield was 19089.25 kg/hm². When the optimal combination of applying fertilizers was 434.20 kg/hm²N, 90.11 kg/hm² P2O5, 213.92 kg/hm² K2O, the eligibility products ratio could reach the highest at 84.95%. It was found that there were significant effects on the contents of total glucosinolates and glucoraphanin by applying N fertilizer, but not by P and K fertilizers. When N fertilizer application reached 408.78 kg/hm² and 394.62 kg/hm², total glucosinolates and glucoraphanin content would get to maximum, respectively. © 2010 Elsevier Ltd.

Abstract:Electrical and electronic products' waste rapid growing caused serious environmental problems. The recycling of waste PCBs had been noticed. The possibility of preparation of the renewable composite panels using non-metallic scraps after air sorting of waste printed circuit boards have been studied and the changes of the tensile strength, bending strength and impact strength of the composite material according to different filler particle size, dosage and modifier has been investigated. The research results showed that using maleic anhydride stem grafting polypropylene (MAH-g-PP) as the modifier, taking polypropylene S700 as the substrate resin, and choosing 20% adding dosage of the 0.125-0.3mm non-metal powder fragments, the plate mechanical properties are superior, and the application prospect is widespread.

Abstract:A sponge-associated bacterium, Winogradskyella poriferorum strain UST030701-295T was cultured up to 100l for extraction of antifouling bioactive compounds. Five poly-ethers were isolated and partially characterized based on nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS); two of them showed inhibitory effects on biofilm formation of marine bacteria and larval settlement of macro-foulers but did not produce any adverse effects on the phenotypes of zebra fish embryos at a concentration of 5μgml^-1. The effect of culture duration on the production of the poly-ethers and the bioactivity of the relevant extracts was monitored over a period of 12days. The total crude poly-ether production increased from day 2 to day 5 and the highest bioactivity was observed on day 3. The poly-ethers were found to be localized in the cellular fraction of the extracts, implying their natural occurrence. The potent bioactivity of these poly-ethers together with their high natural abundance in bacteria makes them promising candidates as ingredients in antifouling applications. © 2011 Elsevier Ltd.

Abstract:The oxidative desulfurization for a simulated oil(S content 1 540×10^-6) consisting of model sulfur compounds of dibenzothiophene(DBT) and toluene solvent in a H2O2/WO3/ZrO2 oxidative system was studied. The influence of oxidation temperature, reaction time, the amount of oxidant and the dosage of catalyst on the conversion of DBT were investigated. The experimental results reveal that under an optimum oxidative desulfurization condition with the temperature of 50°C, the reaction time of 90 min, the oxidant dosage of V(oil):V(H2O2)=20:1 and the catalyst dosage of 0.02 g/mL oil, more than 96% of DBT are oxidized to dibenzothiophene sulfone(DBTOs) that can be easily removed. Furthermore, the oxidation kinetics of dibenzothiophene was investigated. The oxidation of DBT can be treated as a first-order reaction, the apparent activation energy Ea is 55.37 kJ/mol and the pre-exponential factor A is 3.35×10⁷ min^-1.

Abstract:Using layered double hydroxides (LDHs)-chitosan (Chit) composite as enzyme immobilization matrix, the developments of cholesterol biosensor were achieved by both electrooxidation and electroreduction of the enzymatic-generated hydrogen peroxide based on cholesterol oxidase (ChOx) and horseradish peroxidase (HRP). Amperometric detection of cholesterol was evaluated by holding the modified electrode at 0.55 V and 0 V (vs. SCE), for ChOx/LDHs-Chit/Pt and ChOx/HRP/LDHs-Chit/GCE, respectively. The linear dynamic ranges of anodic and cathodic detections of cholesterol were between 5 × 10^-7 to 8 × 10^-4 M and 4 × 10^-8 to 6 × 10 ^-4 M, respectively. The detection limits were determined to be of 1 × 10^-7 and 4 × 10^-8 M with anodic and cathodic processes, respectively. At potential of 0 V, ChOx/HRP/LDHs-Chit/GCE bienzymatic mediated system exhibited excellent selectivity and stability. © 2011 Elsevier B.V. All rights reserved.

Abstract:The paper studies deeply the problem of mining the multi-dimensional frequent paths from the gigantic path data set created by a radio frequency identification (RFID) system applied to supply chain management, and proposes the Dim-path algorithm and the Path-dim algorithm, two methods for mining closed multi-dimensional frequent paths in RFID databases. Base on the characteristics of RFID data, the two methods divide RFID data into three parts of the path independent dimensions, the location data, and the duration data, and mine these parts with multi-dimensional analysis and sequential data mining to improve the efficiency of the methods. The experimental and analytical results show that the algorithms of Dim-path and Path-dim can rapidly and efficiently mine the multi-dimensional frequent path.

Abstract:The generalized coupled thermoelasticity based on the LordShulman theory is considered to study the transient thermoelastic response of functionally graded rectangular plates. The state equations of functionally graded rectangular plate subjected to time-dependent thermal loads were established by using of state space approach, in which three displacement components, three stress components, the temperature and the heat flux were chosen as state variables. By giving simply supported boundary conditions and assuming that the material properties of the plate have an exponential law distribution along the thickness-coordinate, the equations were solved by the numerical Laplace transformations and shooting methods for transient thermal responses of a three dimensional functionally graded rectangular plate due to a thermal shock on its top surface. Effects of the volume fraction distributions of material constituents on the thermal responses, including the temperature change, the displacement and the stresses distributions were investigated. © 2011 Elsevier Ltd.

Abstract:The self-assembly behavior of mixed systems consisting of amphiphilic chitosan derivatives C. n-OCMCS (n= 4, 6, 8) and the conventional cationic surfactant cetyltrimethylammonium bromide (CTAB) is investigated. Transmission electron microscopy (TEM), dynamic light scattering (DLS), small-angle X-ray diffraction (XRD), UV-vis spectra, and zeta potential measurements have been utilized to characterize the microstructures of C. n-OCMCS/CTAB mixtures in aqueous solutions. Spherical vesicles are formed spontaneously in the C. n-OCMCS (n= 4, 6, 8)/CTAB mixed systems, and the increased hydrophobic chain length of C. n-OCMCS enhances the ability to form vesicles. The addition of NaBr with higher concentrations to the vesicle system transforms vesicles into micelles, and an increase in temperature decreases the vesicle size. The results indicate that the main driving forces controlling vesicle formation may be attributed to the strong electrostatic interactions as well as the hydrophobic interactions, and also the hydrogen bonding between C. n-OCMCS molecules. © 2011 Elsevier Inc.
