The Development of Poetry Helped by Ancient Postal Service in the Tang Dynasty
No full textThe spread of poetry by way of ancient postal service in Tang dynasty is an important subject in studying the development of Tang poetry. The ancient postal system in Tang dynasty included both water route and land route which covered every corner of the country, formed a highly developed and strict system. Besides transmitting government decrees and transporting officials and goods, the ancient postal service also helped the development of Tang poetry. Many historical documents proved that ancient postal service in Tang dynasty ensured an immediate transportation between poets and contributed to the wide-spread of the poetry, and it also served as a bridge between the poets who were in great distance and then helped to form different poetry schools and fashion.</jats:p
Implementation of Pavement Evaluation Tools
Get PDFThe objective of this project was to render the Falling Weight Deflectometer (FWD) and Ground Penetrating Radar (GPR) road assessment methods accessible to field engineers through a software package with a graphical user interface. The software implements both methods more effectively by integrating the complementary nature of GPR and FWD information. For instance, the use of FWD requires prior knowledge of pavement thickness, which is obtained independently from GPR.Tang, Shuling; Guzina, Bojan; Labuz, Joseph. (2013).

Structural Evaluation of Asphalt Pavements with Full-Depth Reclaimed Base
No full textCurrently, MnDOT pavement design recommends granular equivalency, GE = 1.0 for non-stabilized full-depth
reclamation (FDR) material, which is equivalent to class 5 material. For stabilized full-depth reclamation (SFDR),
there was no guideline for GE at the time this project was initiated (2009). Some local engineers believe that GE of
FDR material should be greater than 1.0 (Class 5), especially for SFDR. In addition, very little information is
available on seasonal effects on FDR base, especially on SFDR base. Because it is known from laboratory studies
that SFDR contains less moisture and has higher stiffness (modulus) than aggregate base, it is assumed that SFDR
should be less susceptible to springtime thawing.
Falling Weight Deflectometer (FWD) tests were performed on seven selected test sections on county roads in
Minnesota over a period of three years. During spring thaw of each year, FWD testing was conducted daily during
the first week of thawing in an attempt to capture spring thaw weakening of the aggregate base. After the spring
thaw period, FWD testing was conducted monthly to study base recovery and stiffness changes through the
seasons.
GE of SFDR was estimated using a method established by MnDOT using FWD deflections, and the GE of SFDR is
about 1.5. The value varies from project to project as construction and material varies from project to project. All
the materials tested showed seasonal effects on stiffness. In general, the stiffness is weaker in spring than that in
summer and fall.Department of Civil Engineering, University of Minnesota; Minnesota Department of TransportationTang, Shuling; Cao, Yuejian; Labuz, Joseph F.. (2012).

Impacts of shale gas wastewater leaks on neighboring crops: Physiological and morphological responses of tomatoes
Get PDFAs shale gas extraction expands, the volume of flowback and produced water (FPW) from hydraulic fracturing increases, raising concerns about the potential ecological risks of leaks. In this work, we mixed tap water with different proportions of FPW to simulate various leak scenarios. Tomatoes were irrigated using these mixtures or using FPW treated with multi-stage pre-treatment and advanced membrane technologies to assess the effects on tomato seed germination, plant vigor, element accumulation, and fruit gene expression. Compared to tap water irrigation, all three dilution ratios of FPW inhibited seed germination and growth to varying degrees, significantly reduced tomato biomass and fruit yield, and caused the fruit to exceed safe limits for Pb and Cr. In the lowest dilution group, the germination rate was only 17 %, and total biomass decreased by 55 %. Even in the highest dilution group, fruit yield was 11 % lower than the control. Additionally, the dilution showed high salt accumulation toxicity, with yellowing at the edges of the leaves. Applying treated FPW accelerated tomato growth and increased the yield of tomato hairs, with total biomass rising by 38 %. Finally, a large number of differentially expressed genes were detected in the fruits irrigated with FPW. These genes are irelated to carbon and nitrogen metabolism, affecting the synthesis of carbohydrates and proteins. These findings provide insights into the risks associated with shale gas FPW leakage and offer guidance for the reuse of treated FPW

No full textResearch on Low-Carbon Building Development and Carbon Emission Control Based on Mathematical Models: A Case Study of Jiangsu Province
No full textThis paper investigates the development of low-carbon buildings and carbon emission control in Jiangsu Province, China, utilizing a mathematical model. Through correlation analysis and principal component analysis, the carbon emissions of the entire life cycle of residential buildings are evaluated, and a Grey Prediction Model is established. The study shows that the annual carbon emission from air conditioners is 370.92 kg, given an annual electricity consumption of 1324.71 kW and a carbon emission of 0.28 kg per kWh. It identifies the key carbon emission indicators, including precipitation, temperature, energy consumption, building area, construction materials, water, natural gas, and waste. Principal component analysis ranks building area as the most significant factor. Using the GM (1,1) model, the carbon emissions of Jiangsu Province in 2024 were predicted to be 1.5576 million tons by historical data. Emission reduction suggestions are proposed, such as constructing thicker walls, increasing green spaces, reducing construction waste, and promoting balanced economic development. Moreover, prioritizing insulation materials in building design can reduce winter energy consumption since energy consumption is higher in winter than in summer. This research supports China’s goals of achieving a carbon peak by 2030 and carbon neutrality by 2060 while encouraging low-carbon technological innovation and improving people’s living standards. This study also emphasizes the importance of locally tailored strategies for effective emissions reduction
