The harsh natural environment on the Qinghai–Tibetan Plateau has a detrimental effect on the growth of vegetation. Elymus dahuricus, a widely distributed perennial herb on the Qinghai–Tibetan Plateau, is highly adapted to alpine regions. To unveil the mechanism of E. dahuricus adaptation to high altitude on the Qinghai–Tibetan Plateau, the relative photosynthetic characteristics and physiological...
In this study, a combination of indoor culture and high-throughput sequencing was used to analyze changes in nutrients and fungal communities in black soil after the addition of biomass charcoal. The following conclusions were drawn: 1) After six months of constant temperature, black soils containing biomass carbon changed in physicochemical properties. For example, soil pH, organic matter, water...
The application of nitrogen fertilizers can improve the soil environment and influence the nutrition and quality of plants; there are also significant impacts of soil types on soil microbial communities. Research on the coupling effects between the rates of nitrogen fertilizer and the soil types on soil microbial metabolic activities under field conditions are currently lacking. In this study, we...
Soil in western Jilin, China has the properties of a saline soil, seasonal frozen soil, and a dispersive soil, in which the freezing process can induce many engineering and environmental problems, including soil secondary salinization and frost heave. During the freezing process, water, heat, stress, and even solute interact with each other. Water migration plays an important role in this process...
Thallium (Tl) is a typical trace metal of extreme high toxicity. As a concomitant element, Tl is widely found in various sulfide minerals and K-containing rock minerals. The outburst of Tl pollution in drinking water sources of the northern branch of the Pearl River in China as reported in 2010 has greatly aroused public concerns about Tl pollution in China. Apart from typical sources of Tl pollution...
An experimental study and numerical calculation are conducted to investigate the crack propagation in a 2D woven composite. Crack propagation tests of single-layer composite plate specimens permit this process to be directly followed. Analysis of their fracture surfaces reveals crack propagation paths, fracture mode, and damage mechanisms. The load–deflection curve represents the crack propagation...
Background: Osteosarcoma (OS) is a common malignant tumor that predominantly occurs in adolescents. Its most common metastasis is to the lungs. As shown in our earlier study, lysosome-associated membrane glycoprotein 3 (LAMP3) is highly upregulated in metastatic OS. However, its role in the regulation of OS cell viability and apoptosis remains unknown. Methods: We knocked down and overexpressed LAMP3...
