Typical tripod foundations are designed using deterministic computational models according to relevant standards and codes. However, for more cost-safety balanced design, uncertainties in significant parameters should be considered in preliminary design to ensure meeting a specific probabilistic safety target in the context of the complex configuration of a tripod structure. In this article, uncertainties...
This paper studies the characteristics of marine water quality monitoring data monitored by photoelectric sensor network, mines the potential information from the massive data. on account of the continuous accumulation of monitoring data, this paper focuses on the study of database with numerical attribute and proposes a rule updating algorithm for solving the rule maintenance issues caused by changes...
The value of agro-ecosystem services is closely related to crop yield. As a production input component in an agro-ecosystem, agro-ecosystem services have practical value. It is generally believed that agro-ecosystem services are substitutes for purchase investment and can decrease agricultural production costs. Crop yield increases may negatively affect agro-ecosystem protection, and conversely, agro-ecosystem...
Due to the great danger of the collision of oil tankers, lots of research on the collision of oil tankers has been carried out. But, at present, the research on the collision of oil tankers mainly focuses on the loading condition of the struck ship, ignores the impact on the loading condition of the striking ship. However, during the actual oil tanker collision, the striking ship is generally in the...
Understanding the response of soil respiration to changes in temperature and moisture is critical to accurately assess the impact of afforestation on regional carbon balance. In order to investigate the response of soil respiration to soil temperature and moisture, we partitioned soil respiration into three components (heterotrophic respiration, root respiration, and rhizomicrobial respiration) using...
Background: Bamei pigs are special germplasm resources in Qinghai. In the specific environment of the Qinghai plateau, local breeds, through long-term natural and artificial selection, have acquired a relatively stable population structure and genetic diversity. This study revealed Bamei pigs’ genetic diversity at the molecular level and the degree of introgression of commercial breeds into Bamei...
Background: Mishandling of intracellular chloride (Cl−) concentration ([Cl−]i) in cerebrovascular smooth muscle cells is implicated in several pathological processes, including hyperplasia and remodeling. We investigated the effects of ClC-2-mediated Cl− efflux on the proliferation of human brain vascular smooth muscle cells (HBVSMCs) induced by angiotensin II (AngII). Methods: Cell proliferation...
Background: Although significant advances have been made in understanding the mechanisms of macrophage response to Staphylococcus aureus infection, the molecular details are still elusive. Identification of the essential genes and biological processes of macrophages that are specifically changed at different durations of S. aureus exposure is of great clinical significance. Methods: We aimed to identify...
Although the treatment for recycling chrome in tanning effluents is relatively mature, the post-tanning processes have no corresponding effective technology due to the lack of knowledge about the effluents. In this work we investigated the composition and properties of rewetting and neutralizing effluents in posttanning processes. Goat skins were tanned with sulfate chrome liquor of alkalinity 33%...
In order to assess the spatial distribution and the potential pollution risk of nickel (Ni) and vanadium (V) in Shuangtaizi Estuary in China, the water and the surface sediments were collected to determine V and Ni content in specified sites. The data indicated that the estuary was contaminated by Ni, while V content was low. Total concentrations of V in river water ranged from 0.212 to 0.374 μg/L,...
Rapid and extensive economic development in China has resulted in a dramatic increase in the consumption of energy and resources with negative ecological effects. This study sought to define the concept of social-ecological systems (SES) resilience to determine whether a given system can effectively withstand these adverse effects per its quantitative level of resilience. The information entropy method...
