Influence of air conditioning and mechanical ventilation (ACMV) systems on indoor microbial aerosols
Abstract:It is by now well established that most humans spend 70%–90% of their time in the mechanically ventilated buildings, in which the air conditioning and ventilation (ACMV) systems are commonly employed to provide fresh and clean air for indoor occupants. The air supplied to indoor environments inevitably passes over ACMV system and the interaction between the air and the ACMV surfaces can modify microbial air quality. Therefore, understanding how the ACMV influence biological aerosols can contribute to more incisive research to characterize indoor microbiology and associated health consequences. Such understanding is also essential for designing effective engineering controls to reduce bioaerosol exposure risks. Important challenges facing further studies are described along with several opportunities for near-term progress advancing knowledge about indoor microbial aerosols along with the interaction of ACMV system. Such progress is fundamental to efforts to better understand how the micro biome of indoor environments interacts with human health and wellbeing.

Title:Compensation Mechanism of Closed - Loop Supply Chain Based on Remanufacture under Government Participation
Abstract:In recent years, insufficient resources and environmental pollution capture human's attention. Closed-loop supply chain provides researchers a new perspective to study how to solve these problems. In this paper, we study one closed-loop supply chain with a single manufacturer and a retailer under the government participation. Through the established game models and comparison study, our study shows how supply chain balances its three taking-back channels. We also find that in theory, the best way for the government to compensation the closed-loop supply chain is offset the market. But because of the market complex and the theory of "Revenue-sharing contract", we finally designed a better compensation mechanism to the government.

Title:Examination on Risk Prevention Measures for Environment and Safety of Food Plants in Japan
Abstract:Risk prevention measures to secure both pleasant environment and safety are indispensable particularly to food plants. In this study, current situations and causes of troubles, affairs and accidents which have taken place in Japanese food plants are reviewed. In addition, the introduction of human-based strategies integrated with IT/IoT technologies as well as sampling methods for airborne microbes which have been being highlighted these days is proposed as measures to protect environment and safety of food plants.

Title:The evolutionary game analysis of cross-regional ecological compensation - based on the perspective of the main functional area
Abstract:Under the new normal, the carrying capacity of ecological environment in China has reached or approached the upper limit. The root cause is the lack of an endogenous mechanism for the protection and compensation of forest resources. Therefore, clarifying the game relationship between stakeholders can help to break through the dilemma. Based on the analysis of the logical relations among the main stakeholders within the scope of the main functional areas, and then constructing an evolutionary game model between beneficiary regions and the protected regions.The results show that in cross-regional ecological compensation, the optimal strategy of “protection-compensation” can not be achieved by the autonomous choice of the main functional area governments, which must introduce the “restraint-encouragement” mechanism of the central government to standardize the behavior of the function area governments. It makes protect regional governments choose "protection" strategy and benefit regional governments choose "compensation" strategy.

Title:The Spatial-Temporal Characteristics of Urban Construction Land Expansion in Wuhan, Central China
Abstract:Data of construction land in Wuhan city were obtained from remote sensing image in different periods. Based on the spatial analysis function of GIS, the characteristics of construction land expansion were identified by several methods to analyse the spatial-temporal features of Wuhan city area from 1995 to 2015, which included expansion speed, expansion elasticity, contribution rate of expansion, centre-of-gravity shift, and quadrant orientation. The results showed that the construction land area increased gradually from 1995 to 2015 in Wuhan city, and the expansion speed first increased and then decreased. The direction of construction land expansion in Wuhan city was expanded to the southwest significantly. The construction land expansion can’t meet the needs of population growth. Jiangxia district contributed most to the expansion of Wuhan city.

Title:The spatial-temporal differences in coupling relationship between urbanization and eco-environment—a case study of the urban agglomeration in the middle reaches of the Yangtze River
Abstract:Exploring the coupling coordinated relationship between urbanization and eco-environment of the urban agglomeration in the middle reaches of the Yangtze River (UAMRYR) from 2000 to 2015 can provide a theoretical basis for the overall planning and healthy development of the region. Therefore, in this article, we took 31 cities of the UAMRYR as the research area, and established an evaluation system to calculate the urbanization level and eco-environmental quality. Then, using entropy method and coupling measurement model, we analyzed the coupling coordination relationship between urbanization level and eco-environmental quality from spatial and temporal perspectives. Temporally, the coupling degree (CD) and coupling coordinated degree (CCD) continually rose during the 16 years. Spatially, the coordinated development level of urbanization level and eco-environmental quality had significant spatial differences. The CD presented the “northwest-southeast” spatial characteristics corresponding to high-low distribution. The CCD showed an inverted Y-shaped spatial pattern that gradually decreases outward from the provincial capital city. The coordinated development level of urbanization and eco-environment in the UAMRYR showed a central-periphery spatial pattern, and had an obvious spatial variation.

Title: Improvement of Rainwater Infiltration Property and Its Effect on the Corresponding Storage Capacity of Soil in Urban Green Space
Abstract:The soil permeability of urban green space is the main factor affecting hydrological cycle, and it plays a very important role in promoting rainwater infiltration, replenishing groundwater and reducing peak flow. In order to enhance the storage and infiltration ability of soil, different types and contents of conditioner are added to study the laws of the changes in permeability of various soils. The results showed that straw and sawdust can effectively increase the permeability coefficient of soil. According to the comparison under the same conditions, the improvement effect of straw is slightly better than sawdust, but no order of magnitude difference. The sandy soil reformed by 3.6% straw or 4.2% Sawdust and the loam reformed by 29.5% Straw or 30.2% Sawdust can meet infiltration requires of rainwaterwith the 10 years of rainstorm recurrence period. The clay is not suitable for urban green space soils with higher rainwater storage and infiltration requirements. The reformed green space can effectively reduce the runoff peak flow and delay the generated time of the runoff. The higher the content of the modifier, the more obvious the advantage of promoting the hydrological cycle and reduce the runoff.

Title: Study on performance of old composite pavement reclaimed material in cement stabilized macadam base
Abstract: For the old composite pavement, there are two regeneration methods: the overall recycling asphalt pavement and the cement concrete pavement and the stratified recovery. C-B-3 gradation and cement content of 5% were used. The total content of recycled aggregate was 0, 30%, 50%, 70% and 100% and the proportion of RA and RAP was about 1:2. The feasibility of recycling composite pavement to cement stabilized macadam base was studied through compaction test, unconfined compressive strength test and dry shrinkage test. The results show that the strength of recycled cement stabilized macadam is generally higher than that of ordinary cement stabilized macadam. The strength of regenerated cement stabilized macadam can meet the strength requirements under most traffic volume of the highways in the standard. The gradation of the mixture by stratified recovery is more uniform and the quality of the mixture can be better controlled. The addition of NA has a negative effect on the dry shrinkage properties of recycled cement stabilized macadam. However, mixing RAP into recycled cement stabilized macadam can reduce the sensitivity of materials to water and enhance the dry shrinkage property of materials.

Title:Study on purification effect of infiltration materials to pavement runoff pollution
Abstract: The concentrations of pollutants in pavement runoff are higher than those in other surface runoff normally, which causes serious problems in protecting the environment of receiving rivers and soils. According to the concept of low impact development (LID), a pavement runoff pollution control measure was developed by using infiltration structure. In order to play a superior role in the control of pavement runoff pollution for infiltration structure, purification capacity of four typical infiltration materials was tested. Then, long-term purification efficiency of infiltration materials was explored to suspended solids. Besides, microscopic observation was performed on infiltration materials. Results indicated that purification effects of infiltration materials were significantly different. The purification process can be divided into three stages, which were "rapid upgrading ", "slow upgrading " and "slow reduction ". Finally, Infiltration materials mainly have two modes to intercept runoff pollutants, which were pore adsorption and mechanical interception of the gap between materials.
