Archaea communities widely exist in mangrove forest sediments, but their spatial variations among different distribution areas with salinity gradient in mangrove forest sediments is not well understood. This study used 16S rRNA Miseq sequence to investigate the sediment archaeal community structure and diversity of Bruguiera gymnoihiza mangrove forest in China along three different distribution areas...
Plants, via physiological and molecular processes, respond to unsuitable environmental conditions, resulting in stress tolerance. Most previous studies have focused on plant responses to a single abiotic stress, but the effects of combined water deficit and high temperature stresses are more severe and complex than those due to a single stress. Therefore, our study aimed to explore the differences...
This paper aims to the computing model of quantitative elements in crossing situation based on the separating of different states about vessel’s meeting to study the automatic collision-avoiding plan of given way vessel in crossing situation. Following results are proved by simulations: The accuracy of hydrodynamic model is enough for studying and application for automatic collision-avoiding; computing...
Tooth contact area optimization/meshing of the straight worm pair is vital for improving its operation efficiency. Geometric parameters of a worm helicoid were derived via the gear meshing theory using the equations of the instantaneous contact line. The visualization function and powerful computing capability of MATLAB are used for the numerical analysis where the instantaneous contact line distribution...
This paper evaluates the feasibility and stability of the construction of a super-large-scale filtered tailings storage facility on coal-mining subsidence land. Properties of the coal gangue were analyzed by laboratory tests and change laws of the land subsidence were observed in the field. Comparisons of slope stability between the super large-scale filtered tailings storage facility and conventional...
Breast cancer is the most prevalent cancer among women in the world, with a notable increasing prevalence in recent decades. Many environmental compounds with estrogenic activity, called environmental estrogens (EEs), which are especially persistent organic pollutants, may play important roles in the occurrence and development of breast cancer and even treatment and prognosis. EE compounds, including...
Satellite hardware has reached a level of development that enables imaging satellites to realize applications in the area of meteorology and environmental monitoring. As the requirements in terms of feasibility and the actual profit achieved by satellite applications increase, we need to comprehensively consider the actual status, constraints, unpredictable information, and complicated requirements...
Climate change and human activities influence runoff and sediment load in an integrated way. However, under similar climate conditions the variability in runoff and sediment load is mainly a result of human activities. In this study, the change trends of runoff and sediment load were detected with linear regression analysis for the Beiluo River on the Loess Plateau, China. The impact of human activities...
Carbon productivity is a special indicator that coordinates economic development and climate resource protection. Similar to carbon productivity, electricity carbon productivity (ECP) is defined and researched in our paper since it is an effective way for China’s power industry to realize the low-carbon development path. In this work we have applied the multi-dimensional decomposition method to ECP...
