As proved by the experiment, in the same area of the Danxia landscape, the uniaxial mechanical strength of the conglomerates over the flat grooves is universally higher than the sandstones in the flat grooves.
Also discovered in this research, the developments of flat grooves in the strata of sandstones have certain reasons.
The animal is named for its flat, grooved spines and bristles, which are tipped with white and protrude from a dark brown coat of thin, soft underfur.
Tensile tests of the DP980 steel sheet with the thickness of 1.2 mm are conducted using various specimen geometries including pure shear, dog-bone, and flat grooved specimens.
Four aluminum flat grooved heat pipes with groove widths of 0.2, 0.4, 0.8 and 1.6mm are fabricated and the effect of filling ratio on the thermal performance is experimentally studied for four different heat flux values of 2.1, 3.2, 4.2 and 5.3W/cm2.
Results show that the environment with acid rains tended to come into being more easily in the late Cretaceous period because of the frequent eruptions of volcanoes; and the environment of the frequent alternations of intensive freezing and thawing in the Quaternary glacial stage and the interglacial stage should have highly promoted the development of many flat grooves in the Danxia landscape.
Father and son Linus Yale (Sr. and Jr., respectively) made a name for themselves with custom-made bank locks until they patented the Yale Lock with the groundbreaking flat grooved key.
The stone has long flat grooves into which the pill maker would press clay or other substances to make long, snaky strings.
Coomassie staining indicated that cell growth and survival was similar on flat PCL, grooved PCL and grooved PCL impregnated with 1 wt.% or 2 wt.% puerariae powder.
Human osteogenic cells (STRO-1+) were cultured on flat PCL, grooved PCL and puerariae powder-impregnated grooved PCL for 5 weeks.
