The total wet-basis weight of urban and rural domestic waste in China is about 500,000,000 tons every year, 60% which comes from dry-basis (about 300,000,000 tons). Single-composition, clean that separated on a dry basis, especially the low-value components such as food plastics, has huge resource recycling potentials. potential added values would be around RMB 926.17 billion, 1,065.98 billion 1,205.81 upon three prices granulated organic-inorganic compound fertilizers. A value for instance,...

The higher contribution of traffic delay to environmental impacts is urging the highway agencies take work zone management into maintenance schemes decision-making. Aiming understand role in user CO2 emissions reduction, this paper firstly developed a practical methodological framework delay-related caused by based on popular life cycle cost analysis approach regard microscopic vehicle operation analysis. method was applied an actual freeway flexible pavement with 15-year design Shaanxi...

The paper demonstrated and discussed a methodology to evaluate evacuation capacity of urban underground road by considering the system from series important views (i.e. guiding system, facility, management, etc). Due different nature criteria involved in assessment activity, Analytic Hierarchy Process set-valued statistics had been chosen compare appraise those indexes that are incommensurable may originate distinct separate areas. And then fuzzy comprehensive evaluation model was developed...

Due to stop-and-go events, bus stops are often treated as “hot spots” for air pollution. The design of should be optimized reduce emissions and exposure transit commuters. objective this study was analyze the impact stop platform types on vehicle individual pollution exposure. Second-by-second data were first collected from one using a portable emission measurement system (PEMS). Microscopic traffic simulation then used estimate overall under six scenarios with different settings. Numerical...

A one-way traffic strategy is widely used in densely populated urban areas to improve efficiency, but its environmental impacts remain largely unclear. This study investigated the effects of a on vehicle emissions along busy corridor Xi'an, China. was done by integrating flow model calibrated onsite data and emission model. The detour distance estimation method proposed so that trade-offs between increased miles traveled (VMTs) improved efficiency corridors could be uncovered. Empirical...

Abstract Hair follicle development is closely associated with wool traits. Current studies reveal the crucial role of microRNAs in regulating specific gene expression by binding to target mRNA involution hair growth and development, thereby Our previous miRNA sequencing showed that oar-miR-377 have special secondary SLC24A2 may be a new candidate using bioinformatics analysis. In this study, regulatory relationship its was determined sheep fibroblasts dual-luciferase reporter assay, RT-qPCR...

High cost and relatively low reliability of stationary sensors hinder the wide spread advanced motorway traffic control measures. In this research, we propose a vehicle trajectory data based variable speed limit (VSL) controller to improve mobility environmental performance motorways. First, model estimator is designed estimate states using directly derived from probe with spacing measurement equipment (PVSMEs). Extended kalman filter (EKF) METANET are employed as assimilation tool process...

The purpose of this paper is to analyze the influence passenger load on diesel bus emissions based real-world on-road emission data collected by Portable Emission Measurement System (PEMS). It also analyzed whether affect accuracy models VSP. results indicate that rates CO 2 , CO, NO X and HC various with different speed acceleration ranges. As for distance-based factors HC, per-passenger decrease rise load. In addition, it found can be omitted properly in low middle bins. But lead an error...

Since its implementation in 2000, China's urban domestic waste separation pilot program has achieved little success. The root cause lies the lack of moisture control for crude from source. If wet-basis is placed bags, collected by bins/cans and transferred vehicles, difficult to be separated collection, transport disposal, a large amount materials lose value recycling. High rapid reproduction microbes leads serious pollution, collection transfer daily upon generation soaring cost. Unsorted...

The objective of this research is to evaluate the impact operating characteristics on vehicle emissions under real-world conditions in Nanjing. and data were collected by using a SEMTECH-DS Portable Emission Measurement System (PEMS). results showed that acceleration mode has most significant emissions, followed cruise, deceleration idling modes. accounts for approximately 50% or more total during trip, lowest proportion. Acceleration CO NOx but relatively less HC emission. Under high (>...

In this work, we present the optimal design method of multimodal traffic strategies in emergency evacuations by considering background traffic. First, lane use configuration public-oriented transport evacuation that considers is presented. Then, feasible are proposed based on application conditions five strategy proposal. Furthermore, transformed into using model to minimize weighted sum public transport, private cars, and target values. Finally, previous case study Wenling used discuss...

As different drivers have driving psychologies when on the same road, headway distance kept by would not be and capacity of this road influenced. This paper is developed to analyze with influence psychology. Another model was found which considered psychology safety based method probability. In paper, between two relative vehicles classified into categories — absolute (AD) (RD). These distances were used as at "safe" "adventure" psychology, respectively. By analyzing reaction process...
