Fatty acid composition of the cypselae of two endemic Centaurea species (Asteraceae) [PDF]

Botanica Serbica, 2017
The fatty acid composition of cypselae of two endemic species from Macedonia, Centaurea galicicae and C. tomorosii, is analysed for the first time, using GC/MS (gas chromatography/mass spectrometry). In the cypselae of C.

An experimental study of the relationship between water content and strength of unsaturated expansive soil on canal slope

Shuiwen dizhi gongcheng dizhi, 2022
The soil layer in the canal first section of the Middle Route of the South-to-North Water Transfer Project (MR-SNWTP) is mainly composed of expansive soil, and changes in water content of the expansive soil affect the stability of the slope.

Study on Creep Characteristics of Expansive Soil in High-Fill Channel of South-to-North Water Transfer Project

Advances in Civil Engineering, 2020
In the Nanyang section of the midroute of the South-to-North Water Transfer Project, the expansive soil is often used as a filler for high-fill channels. After the channel is stabilized, the expansive soil undergoes creep deformation over time.
