This paper focuses on land resource consumption due to urban sprawl. Special attention is given to shrinking regions, characterized by economic decline, demographic change, and high unemployment rates. In these regions, vast terrain is abandoned and falls derelict. A geographic information system （GIS） based multi-criteria decision tool is introduced to determine the reuse potential of derelict terrain, to investigate the possible reuse options （housing, business and trade, industry, services, tourism and leisure, and re-greening）, and to visualize the best reuse options for groups of sites on a regional scale. Achievement functions for attribute data are presented to assess the best reuse options based on a multi-attribute technique. The assessment tool developed is applied to a model region in Germany. The application of the assessment tool enables communities to become aware of their resources of derelict land and their reuse potential.

【目的】研究酸性饲粮对东方蜜蜂微孢子虫繁殖和意大利蜜蜂免疫力的影响,验证酸性饲粮是否能够防治蜜蜂微孢子虫疾病,为在养蜂中合理使用酸性饲料提供科学依据。【方法】以意大利蜜蜂为研究对象,选取400只新出房蜜蜂,随机分为4组,分别为对照组、微孢子虫组、微孢子虫+柠檬酸组(含50 g·L^(-1)柠檬酸)和微孢子虫+醋酸组(含400 mL·L^(-1)醋酸),每组100只,检测并分析感染后第1天和第3天免疫基因的相对表达量,统计分析感染7 d后蜜蜂体内微孢子虫数量和蜜蜂存活率。【结果】4个试验组之间的存活率差异极显著(P0.05)。在微孢子虫组中,蜜蜂感染3 d内检测到11个免疫基因的相对表达量未显著下降(P>0.05),但酸性饲粮处理组中的部分免疫基因PGRPSC4300和Abaecin的表达量显著下降(P<0.05)。【结论】含有50 g·L^(-1)柠檬酸和400 mL·L^(-1)醋酸的饲粮无法抑制微孢子虫繁殖,也不能提高蜜蜂免疫力和存活率,不适用于治疗蜜蜂微孢子虫病。

A moving collocation method has been shown to be very effcient for the adaptive solution of second- and fourth-order time-dependent partial differential equations and forms the basis for the two robust codes MOVCOL and MOVCOL4. In this paper, the relations between the method and the traditional collocation and finite volume methods are investigated. It is shown that the moving collocation method inherits desirable properties of both methods： the ease of implementation and high-order convergence of the traditional collocation method and the mass conservation of the finite volume method. Convergence of the method in the maximum norm is proven for general linear two-point boundary value problems. Numerical results are given to demonstrate the convergence order of the method.

The feasibility of improving the overall performance of medium Mn steels was demonstrated via tailoring the initial microstructure and cold rolling reduction. The combined effects of cooling patterns after hot rolling （HR） and cold rolling （CR） reductions show：（1） as the cooling pattern varied from furnace cooling （FC） to oil quenching （OQ）, the intercritically annealed microstructure was dramatically refined and the fraction of recrystallized ferrite dropped, regardless of CR reductions. This resulted in both high yield/ultimate tensile strengths （YS/UTS） but low total elongation to fracture （El）; （2） as the CR reduction increased from 50% to 75%, the OQ-samples after annealing exhibited a more refined microstructure with relatively higher fractions of retained austenite and sub-structure, leading to higher YS and UTS but lower El; whereas the FC samples appeared to exhibit little difference in overall tensile properties in both cases. The differences in microstructural evolution with cooling patterns and CR reductions were explained by the calculated accumulated effective strain （eAES）, which was considered to be related to degrees of recovery and recrystallization of the deformed martensite （α＇）. The optimal tensile properties of -1 GPa YS and -40 GPa.% UTSxEI were achieved in the OQ-50%CR annealed samples at 650 ℃ for 1 h. This was quite beneficial to large-scale production of ultra-high strength steels, owing to its serious springback during heaw cold working.

The recent China's growth slowdown is both cyclical and secular, driven by external and internal factors. In this article, I highlight several key internal factors that have hindered China's growth in recent years. These include worsening misallocation of resources and declining growth of total factor productivity, plus rising household income inequality and debt overhang in the face of tightened liquidity constraint. All of these show the urgency for deepening reforms in China's key macroeconomic landscapes in order to remove institutional barriers and distortions deep-rooted in the nation's economic and financial structure, and to correct fundamental imperfections of its socialeconomic system. 1 argue that such refonns are of critical importance for China's pursuit of healthy and sustainable growth and of balanced and adequate development going forward.

The numerical solution of the harmonic heat map flow problems with blowup in finite or infinite time is considered using an adaptive moving mesh method.A properly chosen monitor function is derived so that the moving mesh method can be used to simulate blowup and produce accurate blowup profiles which agree with formal asymptotic ***,the moving mesh method has finite time blowup when the underlying continuous problem *** situations where the continuous problem has infinite time blowup,the moving mesh method exhibits finite time blowup with a blowup time tending to infinity as the number of mesh points *** inadequacy of a uniform mesh solution is clearly demonstrated.

Knowledge of plant responses to soil water availability is essential for the development of effcient irrigation ***,notably different results have been obtained in the past on the responses of various physiological indices for different plants to soil water *** this study,the responses of various plant processes to soil water availability were compared with data from pot and field plot experiments conducted on maize(Zea mays L.).Consistent results were obtained between pot and field plot experiments for the responses of various relative plant indices to changes in the fraction of available soil water(FASW).A threshold value,where the relative plant indices began to decrease with soil drying,and a lower water limit,where the decline of relative plant indices changed to a very slow rate,were *** demand not only influenced the transpiration rate over a daily scale but also determined the difference in transpirational response to soil water availability among the transient,daily and seasonal time *** the seasonal scale,cumulative transpiration decreased linearly with soil drying,but the decrease of transpiration from FASW = 1 in response to water deficits did not affect dry weight until FASW = *** the other hand,the decrease in dry weight was comparable with plant height and leaf ***,the plant responses to soil water availability were notably different among various plant indices of maize and were influenced by the weather conditions.

The Jin-Neelin model for the El Nio–Southern Oscillation(ENSO for short) is considered for which the authors establish existence and uniqueness of global solutions in time over an unbounded channel domain. The result is proved for initial data and forcing that are sufficiently small. The smallness conditions involve in particular key physical parameters of the model such as those that control the travel time of the equatorial waves and the strength of feedback due to vertical-shear currents and upwelling; central mechanisms in ENSO *** the mathematical view point, the system appears as the coupling of a linear shallow water system and a nonlinear heat equation. Because of the very different nature of the two components of the system, the authors find it convenient to prove the existence of solution by semi-discretization in time and utilization of a fractional step scheme. The main idea consists of handling the coupling between the oceanic and temperature components by dividing the time interval into small sub-intervals of length k and on each sub-interval to solve successively the oceanic component, using the temperature T calculated on the previous sub-interval, to then solve the sea-surface temperature(SST for short) equation on the current sub-interval. The passage to the limit as k tends to zero is ensured via a priori estimates derived under the aforementioned smallness conditions.
