The Bayes estimate of H 0 is 61 6< H 0<66 8(km·s -1 ·Mpc -1 ), with 68 3% confidence and the universal age derived by H 0 is (15±1)×10 9 a, which is consistent with the value derived by spherical cluster (15±3)×10 9 a.
Preparation of spherical Bi_2O_3 powder by precipitation process
at the deformation temperature of 508℃ and strain rates ranging of 0.01- 20 s-1, the stable stresses are about 4.78-9.09 MPa and 7.87-26.21 MPa for the samples with spherical and dendritic primary a-Mg grains, respectively.
When the strain rates and deformation temperatures are 0.1, 10 s-1 and 480-556℃ respectively, the stable stresses of the samples with spherical primary α-Mg grains are about 3-17.13 MPa, but those with dendritic grains are about 6-31.6 MPa;
With PredictProtein software online from Colombia University for structure analysis, it showed that 28.96% helix, 25.69% sheet, and 45.35% loop in secondary structure of Vip3A-WB5. The whole Vip3A-WB5 protein appeared as compact, as a globular domain in tertiary structure.
The results show that the microstructure of the composite coatings is with the bedded matrix phase FeAl2O4 and the horniness phase Al2O3,and the spheroidal Fe phase is distributed in the bedded coatings.
makes certain the direction of coefficient of permeability with variation function by modeling globosity function; divides the sandlayers into five types by using the method of flowing cell based on three parameters, that is X h, KXh and h/H, and accounts the favorable region.
The results are as follows: The method can get brown-tan,well-dispersed ultrafine powder which has the better fluidity and seems very loose; the sample particles assume globosity and its pellet diameter is about 10 nm.
Strain AJ6 is a Gram-negative rod whose size is 0.2-0.6 by 1.6-4.2 μm, wherein a few cells are globular.
Numerical analysis of weld pool geometry in globular-transfer gas metal arc welding
According to the features of the globular-transfer mode, the additional heat energy from molten metal droplets was treated as a plane or volumetric heat source term to correspond to different welding conditions.
In order to improve research into Punctatus, more than ten thousand globular fossils were recovered by means of "Chemistry Retting".
On the basis of the study of these globular fossils, a series of Punctatus fossils with cone parts and finely preserved soft-tissue mouthparts and fossilized metazoan embryo were recovered.
In the Neritidae, relative shell globosity tends to increase interspecifically from low to high shore levels; most high-shore species have strong shell sculpture, with the base of the shell only slightly excavated.
Non-neutral variation studied in this thesis is the globosity of shells.
