Coordinated variation in root and leaf functional traits of Hippophae rhamnoides treated at different stump heights in feldspathic sandstone areas of Inner Mongolia

open access: yesFrontiers in Plant Science, 2023
This study was aimed to clarify the effects of stumping on root and leaf traits as well as the tradeoffs and synergies of decaying Hippophae rhamnoides in feldspathic sandstone areas, and to select the optimal stump height that contributed to the ...

Supersymmetry, Naturalness, and Signatures at the LHC [PDF]

open access: yes, 2006
Weak scale supersymmetry is often said to be fine-tuned, especially if the matter content is minimal. This is not true if there is a large A term for the top squarks.

Determination of the transitional fines content of sand-non plastic fines mixtures

open access: yesSoils and Foundations, 2015
The transitional fines content is the boundary between fines-dominated and sand-dominated behaviour. Experimental and calculation methods for the determination of the transitional fines content of sand-non plastic fines mixtures are summarized based on former studies.

Influence of Fines Content and Particle Shape on Limiting Void Ratios of Sand Mixtures: DEM and AI Approaches

open access: yesBuildings
The mechanical behavior of sand–fines mixtures is governed by their limiting void ratios, which are sensitive to fines content and particle morphology. Conventional empirical correlations often fail to generalize to a wide range of soils, limiting their ...

Response of the fine root morphological and chemical traits of Tamarix chinensis to water and salt changes in coastal wetlands of the Yellow River Delta

open access: yesFrontiers in Plant Science, 2022
To explore the adaptation of the fine root morphology and chemical characteristics of Tamarix chinensis to water–salt heterogeneity in the groundwater–soil system of a coastal wetland zone, T.

Beneficial utilization of ultra-fine dredged sand from Yangtze River channel as a concrete material based on the minimum paste theory

open access: yesCase Studies in Construction Materials, 2022
Ultra-fine sands are dredged periodically in order to maintain the normal activities of the Yangtze River Channel. Finding a new solution for managing these ultra-fine dredged sand becomes a challenge for channel managers.

Effect of Fine Content on Liquefaction Resistance of Saturated Marine Sandy Soils Subjected to Cyclic Loading

open access: yesJournal of Marine Science and Engineering
Offshore wind turbines are subjected to environmental loads such as wind and ocean waves throughout their entire service lives. Saturated sandy soils experience liquefaction under cyclic shear stresses induced by earthquakes or strong wave actions, which

The effect of ceria co-doping on chemical stability and fracture toughness of Y-TZP [PDF]

open access: yes, 1995
The fracture toughness and ageing resistance of yttria, ceria-stabilized tetragonal zirconia polycrystals (Y, Ce-TZP) were evaluated as a function of grain size and ceria content.

Experimental Study on Kaolinite Weathering Sand as Cement Mortar Accelerating Agent

open access: yesAdvances in Civil Engineering, 2022
In this study, the weathered sand from kaolinite mine in Yushan County, Jiangxi Province, China, was tested and analyzed in laboratory. XRD results show that montmorillonite is the main mineral composition of kaolinite weathered sand, and the content of ...

The Cold and Hot Gas Content of Fine-Structure E and S0 Galaxies

open access: yes, 2000
We investigate trends of the cold and hot gas content of early-type galaxies with the presence of optical morphological peculiarities, as measured by the fine-structure index (Sigma). HI mapping observations from the literature are used to track the cold-
