Authors: Li Ping , Yao Yu , Pei Jun Jun , Wu Zhong
Published: March 2013

For old Portland Cement Concrete pavement paved with asphalt concrete surface, the shearing property at the interface is directly related to the service life of pavement. By using the improved shear-strength test machine in laboratory, shear experiments for composite pavement were carried out in cases of different gradations, interface treatments, types of bonding oil and bonding layer thicknesses. The interlaminar anti-shearing strength was also used to determine an optimal interfacial treatment for composite pavement. Experimental results showed that, gradation type of asphalt mixture was less influential to anti-shearing strength of interface; SBS modified bitumen had more excellent anti-shearing performance in several kinds of bonding oil; rougher and exposed-aggregate interface could significantly improve the shear strength of interlayer on composite pavement; the optimal dosages of bonding oil should be determined by contrast test before construction.

Published: March 2013

The rapid development of China’s economics makes it urgent to widen the existing highways especially those located in the south-eastern coastal areas over thick soft soils. Adding a new embankment adjacent to the existing highway embankment is a cost effective choice compared with the traditional methods to build another new one and can reduce the heavy traffic pressure. However, it may also cause some engineering problems including the excessive settlements settlements, road cracks, excessive tensile stresses on the pavement even local or global instability of embankments. So some proper measures should be taken to solve the problems caused by widening is of great importance in engineering practice. A numerical analysis was performed to investigate the effect of different kinds of soft soil treatments including rigid piles, stone columns and prefabricated vertical drains (PVDs) usually used in highway widening projects located in the thick soft soils. It was found that the rigid piles can effectively reduce the additional settlements of the existing embankment induced by widening as well as the settlements of the widened embankment. While the stone columns and PVDs play little role in controlling the additional settlements caused by widening.

Published: March 2013

Breviflavone B is a novel chiral phytoestrogen that mimics the biological functions of 17β-estradiol (E2), an estrogen which is naturally produced in our body. It has exhibited a much higher estrogen receptor (ER) bioactivity than E2 or other phytoestrogens. Breviflavone B specifically activates ER at a low dose without activating other steroid receptors, and inhibits estrogen-stimulated breast cancer cell proliferation at high doses, making it a potential treatment option for breast cancer patients. In this report, a new liquid chromatography aprroach has been developed to isolate Breviflavone B from Epimedium Brevicornum herbal extracts. After passing through DIAION HP20 resin, the ethanolic extract of Epimedium Brevicornum was firstly fractionalized by a Diol column, then further separated by a C18 column using preparative HPLC, and finally purified by an ODS-MCR-HPS column in HPLC under gradient mode. In each stage of separation, the ER bioactivities of the each fraction were measured by estrogen receptor-driven reporter gene bioassays to guide the chromatographic fractionations. The results showed that the new combination of Diol and C18 and ODS-MCR-HPS column chromatography provided better separation selectivity than our previously-reported C18 column chromatography for isolation of Breviflavon B from Epemidium herbs. Pure Breviflavon B was successfully isolated from the ethanolic extract of Epimedium Brevicornum herb via this new approach of chromatographic fractionations guided by the bioassays.

Published: March 2013

The explicit statistical model of concrete temperature variation is difficult to reasonably reflect the nonlinear relationship between the historical information and future information. This article is based on neural network intelligence tools and uses the neural network model to describe the concrete temperature variation during the construction. The relationships between the concrete temperature and initial temperature (pouring temperature), environmental temperature, the cement hydration heat temperature increase, water cooling effect and other factors are nonlinear. Establishing the neural network model of concrete temperature variation, exploring the historical temperature information could predict the future temperature information. Applying the intelligent prediction model to a construction project shows that when compared with the traditional explicit temperature statistical model, the temperature neural network prediction model established in this paper has obvious simplicity and superiority.

One of these features is their complexity, along with difficulties in building models that capture the system in all its important aspects. In a heterogeneous flexible system, the scheduling events or actions could be a combinatorial problem which claims a particular solution. Manufacturing scheduling process, in special for FMS, is a very difficult scheduling problem, because involves all the aspects of the processes: order, resources, transportation system i.e. automated vehicle guided, perturbation factors such as breakdowns of machine, etc. Typically, the scheduling problem is a NP-hard problem modeled in mathematical form. If we simulate n jobs or orders which have to be assigned to the m machines or resources, we will observe that the mathematical solution is a huge number that means (n!)m possibilities of solutions. The challenge of researchers is to solve this equation in a reasonable time with an optimal solution, and of course with minimal resources. Those scientists applied many solutions which became Operational Research-OR or Combinatorial Optimization-CO areas using a various methods: Local Search-LS, Artificial Intelligence-AI, heuristic method, priority rules, memetic or hybrid techniques which combine this techniques.

Due to a lot of projects are involved in oil spill and the process is complex, the injured party lacks the evidence to support the evaluation of the oil spill impact on the environment. Therefore, many oil spill claims event had not been properly resolved. In this paper, we designed an environmental impact assessment system of offshore oil spill for improving the above-mentioned situation. The major functions of this system are data management, query analysis, spatial modeling analysis, evaluation of forecast, user management and so on. Environmental impact assessment system of oil spill can predict and evaluate the oil spill’s impact on environment. It’s significant for the protection of the environment and planning. In addition, it also has a realistic significance for providing some basis for claims issues.

Mathematical modeling and simulation technology is a very important wastewater treatment plant data processing analysis tools. To analysis the wastewater treatment plant operation process, this study was realized on MATLAB and LIB-SVM tools. Determine the five feed water quality indexes (water inflow, pH, temperature, COD, MLSS) as input variables and the effluent COD concentration as output variable. Within the SVM modeling, through the GA algorithm, PSO algorithm and the grid search method to separately carried on the model parameters optimization. Through the verification results show that SVM model predicted the COD concentration average relative error is 0.0165, which has higher accuracy, which can meet the actual requirements of water quality prediction.

Green barriers of western countries restrict the product export of developing countries. This is a new problem on international trade recent years. After China s entry into WTO, green barriers have become a biggest barrier in Chinese foreign trade. This paper provides the system shortage about Chinese green barriers. So China should launch a campaign to construct the system of green barriers according to Chinese Economic backgrounds. This paper also proposes some law countermeasures to set up and improve the Chinese green barrier system.

The Cladophora genus comprises macro benthic green algae, widely distributed in estuaries, rivers, and lakes around the world. It is often a dominant species and influences environmental and ecological systems. Cladophora is a biological material with great development potential due mainly to its significant biomass and the ease with which it can be harvested. Furthermore, because it can live on various carriers or vectors, the growth conditions of Cladophora can affect the group to which it belongs. To investigate the growth of the Cladophora group in the natural environment, this study endeavored to (1) observe the biomass accumulation of Cladophora glomerata on varying substrates, (2) determine whether substrate roughness has an impact on the attachment of C. glomerata, and (3) identify the relationship between the attachment of pioneer diatoms and C. glomerata. Five types of substrate were selected (glass slide, glazed tile, marble, unglazed tile, and wood) and placed in the natural habitat of C. glomerata, a sub-tropical river. After thirty days, unglazed tile produced the largest biomass of 2332.2 dry weight mg/m2, followed by wood (1744.3 dry weight mg/m2), marble (158.1dry weight mg/m2), glass slide (90.7dry weight mg/m2), and glazed tile(36.3 dry weight mg/m2). The results of this study indicate that the type and roughness of the substrate both influence the attachment of C. glomerata and the subsequent development of its population. The existence of biofilm formed by pioneer diatoms on the substrate is also beneficial to the epiphytic growth of C. glomerata. Moreover, the development of pioneer diatoms is associated with the type of substrate and its silicon content.

research of submarine paleochannels has not only a great significance in exploring the evolution of palaeoenvironment of continental shelf but also a practical application value in solving problems on disaster geology and environmental geology in the continental shelf development. Yellow River and Yangtze River both were concentrated in the northern Jiangsu to enter the South Yellow Sea Basin in the Last Glacial, playing an important role in the palaeoenvironment evolution of the South Yellow Sea. On the basis of integrating previous research results and researching a large number of shallow stratigraphic sections of paleochannels in the South Yellow Sea Shelf in detail, identification and research of Yangtze River and Yellow River paleochannels in the South Yellow Sea Shelf are carried out in this paper. Research results show that: the Yangtze River and Yellow River paleochannels in the South Yellow Sea continental shelf are significantly different in the river section, river pattern, major elements, as well as trace elements, clay minerals, carbonate content and heavy mineral assemblages in the river sediments and other aspects. These differences can be used as the evidence for identification of the Yangtze River and Yellow River paleochannels.
Production, Potential and Challenges of Crop Straw in Anhui Province, China
Authors: Chen Qun
Published: March 2013

Crop straw is of great interest economically in Anhui Province due to its potential value as biological resources, industrial raw material, and alternative fuel. In 2008, over 40 million tons of crop straw was produced in Anhui province, 89% of which was from Jianghuai and Huaibei regions with rice, wheat and rape as the major species. So far, crop straw has been used as fertilizer supplement, culture media for edible fungi, and livestock feed in Anhui province. Crop straw is also the fourth largest energy resource on the Earth. Potential for such resource has yet to be fully explored due to lack of research funding, logistic transportation and technology. Enormous challenges remain ahead if crop straw is to be used as an alternative fuel for energy production.

Published: March 2013

Best Management Practices (BMPs) is a good way to control pollution source. Now many BMPs have been collected and stored in database. But they are not available directly by managers due to cognitive differences. In order to recommend suitable BMP to water environment managers for treating specific contaminated river, we model BMP knowledge with ontology. In the paper, we introduce ontology building process, and a wastewater BMP ontology is built and integrated into an environment management decision-making support system. In the end, a BMP recommendation case study is also presented.
