The root mass density
of the vegetation-restored steep gully slopes was 3.0-12.7 times that of the control site (P<0.05).
G = 4.788e9(1 - [sigma]) / ((1 + [sigma])(1 - 2[alpha])) = 7.074x [10.sup.9]N / [m.sup.2] where [sigma] = 0.333 is the Poisson's ratio and mass density
is [rho] = 1420kg / [m.sup.3], [T.sub.exc] = 0.1[micro]s, stiffness-proportional damping matrix was, C = [mu]/[E.sub.eqv] K, and the relaxation constant [tau] of the Maxwell viscosity model was used.
where, A means the area (m2), [delta]i is the damping coefficient (s2/kg), [rho]a is mass density
of air (kg/m3), Lt and h are lengths (m) as shown in Fig.
Previous works have demonstrated that physical parameters of the material (i.e., the mass density
, Young's modulus, and Poisson's ratio), the geometric dimensions of the unit, and the working frequency all have influences on the sound behavior of the unit, including reflected ratio and phase [30-32].
There are two sensible descriptions on the fluid dynamics, Eulerian and Lagrangian descriptions; both are aiming at formulating the equations for mass density
, momentum, and energy in a fluid.
Next, the fibrin clot structure was determined by measuring the OD at 405, 540, 608, and 690 nm after an overnight incubation, and the fiber mass-length ratio, fiber diameter, and fiber mass density
were calculated .
The sensitivity of the graphene-based resonator was much smaller than those of graphyne-based resonators due to the effect of mass density
. The carbon atomic number of graphene is 3984, which is higher than that obtained for graphynes in the analysis, such as 2728 for [gamma] type and 2166 for [alpha] type, although the stiffness of graphene is larger than that of graphyne .
Researchers are investigating a possible link between vitamin K deficiency and an increase in bone fractures, osteoporosis, and lower bone mass density
. And vitamin K may also help to prevent calcification of blood vessels and loss of vessel elasticity.
Effect of ghrelin on bone mass density
: the In Chianti study.
(3) One study reports that short-term use of red clover by postmenopausal women may have small health benefits on bone mass density
, cognitive abilities, and plasma lipid concentrations due to the presence of estrogen-like compounds called isoflavones.
Their early work laid out the mathematics of forecasting and described fronts, showing that they are defined by a change in air mass density
. Changes in wind speed, humidity, or pressure are all secondary.
