Keywords: Heat treatment, Water-absorption Characteristics, Plantation-grown Eucalyptus, Solid-wood products for outdoors.
Abstract: In order to explore the highly value-added potential of plantation-grown Eucalyptus wood,which may be used as solid-wood products outdoors, the heat treatments were carried out on flatesawn boards including heartwood and sapwood in four species of Eucalyptus urophylla, E.grandis,E.urophylla×grandis and E.grandis×urophylla wood under seven levels of 25℃,50℃,100℃,140℃,180℃,220℃,250℃.The water-absorption characteristics were determinated and analyzed on 1-mm-thickness cross section of heartwood and sapwood under all above-mentioned temperature conditions.The results dedicate that: 1) the water-sorption percentage of heartwood on four species of Eucalyptus wood decrease first and then increase with the increase of heat-treatment temperature, and take on the turning point at 100℃. For sapwood, the water-sorption percentage increase first, then decrease, present turning point at 140℃ and arrive at stability when exceeding heat-treatment temperature of 180℃. 2) the changing trend of the water-sorption characteristics in heartwood and sapwood in four species Eucalyptus wood under different heat-treatment conditions take on the certain regularity, i.e. Eucalyptus urophylla >E.urophylla×grandis > E.grandis> E.grandis×urophylla. 3) heat-treatment temperature of 180℃ is more suitable for processing plantation-grown Eucalyptus wood based on the change of water-sorption percentage in four species of Eucalyptus wood. Compared to the other there species of Eucalyptus,it is most potential for Eucalyptus urophyllar to be used as solid-wood products outdoors.

Keywords: Flammulina velutipe, Culture medium, Mother spawn culture, Original spawn culture, Medium composition
Abstract: Cotton shell and wheat bran, as raw materials of mushroom production, are now increasingly difficult to be available with fewer suppliers or high transportation cost. Therefore, new raw materials for mushroom culture badly need to be developed. Possibility of some substitutes for traditional culture medium was investigated in order to meet with nutritional requirements during mother and original spawn culture stage. Three species of flammulina velutipes (Baiyu NO.1, Kin2001 and Kinbai NO.1), were selected, growing in a chamber under environment control. Six substitutes for mother spawn culture and five ones for original spawn culture were developed. All the treatments were carried out repeatedly by five and six times respectively for the two different culture stage. Variance analysis was made based on mycelium length as dependent variable. The result shows that culture medium with 50 g rice straw extract can promote the extend of mycelium length more quickly during the mother spawn culture stage, and culture medium with 22% rice straw for Kinbai NO.1 can significantly reduce the period of full growth during the original spawn culture stage.

Keywords: soybean industry, supply chain, game theory, alliance, node
Abstract: Due to China’s highly liberalized soybean trade, import soybean has great impact on the development of China’s soybean industry. The author proposes that the building of the supply chain of soybean industry is an important way in improving the competitive capability of China’s soybean industry through analysis of the status quo of the development of China’s soybean industry. The definition of soybean supply chain is presented, and the structure, node functions of the supply chain, as well as the construction of relevant support systems are analyzed. At the end the game theory is applied in the analysis of the stability condition of core node enterprises. The paper puts forward a new viewpoint for the research of the development of China’s soybean industry.

5.A Mixed Integer Programming Approach for Supply Chain Management Using Particle Swarm Optimization Algorithm

Keywords:  Mixed integer programming; particle swarm optimization; penalty function; supply chain optimization
Abstract:  As a novel optimization technique, particle swarm optimization (PSO) algorithm works as an evolutionary computation technique and has been applied to solve non-linear problems in many domains. But this algorithm always works as problem-depended so that the application method analysis always attracts researchers’ interests. In this paper we address the research on solving a kind of programming problems- mixed integer programming (MIP) that usually occur in operation or management regions. Following the way of standard PSO algorithm, we give a general formula for MIP and emphasize on constructing a feasible pattern which can be used in PSO so that the constrained condition which most MIP problems happen to are transformed into unconstrained condition by request of PSO algorithm. Finally we give a practical case to prove such methodology and the testing result verifies its validity.

Keywords: Coordination; Supply Chain; Revenue-sharing; Contract Model
Abstract: With the further development of theory of supply chain coordination, revenue-sharing contract theory gains more and more attention. Meanwhile, problems have arisen in the process of the dairy industry rapid development, which are inequality of the interest distribution in the dairy-product supply chain, and the efficiency of supply chain is getting lower. This paper applies the theory of supply chain coordination to establish the revenue-sharing contract model and deduce the scope of revenue distribution coefficient with the purpose of coordinating interest relations among supply chain members. According to the scope of revenue distribution coefficient, members determine the negotiating principles in order to coordinate the dairy-product supply chain node’s interest, and then improve the overall efficiency of supply chain.

Keywords: landfill leachate, contaminant transport, coupling model
Abstract: Based on theory of seepage and solute transport, dynamic coupling model of unsaturation water flow and solute transport is established. The established model is used to model study contaminant transport law in two different penetrability soil under the circumstance of continuous and break pollution source, on the basis of sorption, desorption and biodegradation in soil and water environment. The result reflects contaminant transport law truly, and proves validity of this model. The model provides the theoretical basis for quantitatively predicting space-time distribution of contaminant in landfill soil.
