In recent years, with the rapid economic development of Bohai Economic bay area in China, the atmospheric environmental pollution problem has been of wide concern and has attracted great public attention. In this paper, the data of PM₁₀, SO₂, CO, NO₂, O₃ and PM₂.₅ in 12 cities located around the Bohai Bay area of China were collected in 2016. These 12 cities were divided into coastal and non-coastal...
Flowering at a suitable time is critical for ensuring reproductive success in the plant life cycle. The transition from vegetative growth to reproduction development is finely tuned by environmental and endogenous signals. To date, control of flowering involves five genetically defined pathways. However, the role of type-A response regulator genes in regulation of this process remains largely unclear...
Urbanization has brought about a substantial increase in population growth, and a considerable amount of park green space has been exposed to urban construction land, which has greatly affected the natural and social value of the urban natural capital. Although this problem is serious in developing countries such as China, few studies have been conducted on the basis of a comprehensive evaluation...
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...
The aim of this study was to investigate the effect and underlying mechanisms of short-term high-intensity sound exposure on guinea pigs to mimic the effects of non-lethal anti-riot weapons. A total of 92 male adult guinea pigs were exposed to high-intensity sound at 0 dB, 110 dB and 130 dB for 5 min. Basic clinical observation, repellent behaviour detection, peripheral blood routine examination,...
To study the force and deformation characteristics of subsea mudmat-pile hybrid foundations under different combined loads, a project at a water depth of 200 m in the South China Sea was studied. A numerical model of a subsea mudmat-pile hybrid foundation is developed using the numerical simulation software FLAC3D. The settlement of the seabed soil, the bending moments of the mudmat, and the displacements...
The paper reports the design and tests of the planar autopilot navigation system in the three-degree-of-freedom (3-DOF) plane (surge, sway and yaw) for a ship. The aim of the tests was to check the improved maneuverability of the ship in open waters using the improved nonlinear control algorithm, developed based on the sliding mode control theory for the ship-trajectory tracking problem of under-actuated...
Background: The transcription factor Oct4 plays a pivotal role in the preimplantation development of the mouse embryo. DNA methyltransferase 1 (Dnmt1) maintains the changes in DNA methylation during mammalian early embryonic development. Little is known of the role of Oct4 in DNA methylation in mice. In this study, Kunming white mice were used as an animal model to reveal any correlation between DNA...
Background: Patients with anti-β2GPI antibodies display significantly higher platelet activation/aggregation and vascular endothelial cell damage. The mechanism underlying the correlation between platelet activation, vascular endothelial cell dysfunctions and anti-β2GPI antibodies remains unknown. Methods: In this study, we derived miR-96 and -26a from platelets activated by the antiβ2GPI/β2GPI complex...
