The on-the-spot research and observation of corrosive shape were made for mesh dehiscence of water hat screen cloth in 904L under the working conditions of 6 MPa, 155 ℃, pH 3~7 using H type resin catalyst for producing methyl-ethyl-ketone.
Objective To compare the characteristics of interbody fusion achieved using hat type cervical intervertebral fusion cage ( HCIFC) with those of an autologous tricortical iliac crest graft, Harms cage and Carbon cage in a goat cervical spine model.
目的本研究在活体山羊颈椎上从椎间支撑能力、二期生物力学稳定性及椎间融合组织学方面比较三面皮质骨、Harms椎间融合器(cage)、Carbon cage及自行所研制的帽式颈椎椎间融合器(hat type cervical intervertebral fusion cage,HCIFC)的术后效果。
Indeed, if the coefficients of L are in $W^{1,2}\cap L^{\infty},$ then L can be rewritten in divergence form for which the notion of a "weak" solution can be applied.
The fibroblasts in the satellite foci and the cap areas of a pterygium show some features of tumor cells and may play a vital role in the development and progression of a pterygium.
Meanwhile, based on the ideas from CAP (Certified Assembly Programming) and SCAP (Stack-based Certified Assembly Programming), a reasoning framework was built to verify the properties of object code in a Hoare style.
With "hat" denoting the Banach envelope (of a quasi-Banach space) we prove that if 0>amp;lt;p>amp;lt;1, 0>amp;lt;q>amp;lt;1, ?, while if 0>amp;lt;p>amp;lt;1, 1≤q>amp;lt;+∞, ∝, and if 1≤p>amp;lt;+∞, 0>amp;lt;q>amp;lt;1, ?.
In particular, if the dilation parameter is 21/3, and the lattice subgroup is sufficiently fine, then the "Mexican hat" wavelet, Le-L/2δ, generates a wavelet frame, for which the ratio of the optimal frame bounds is 1.0000 to four significant digits.
First, the axial crash tests of the empty hat sections, aluminum foam and the aluminum foam-filled hat sections were carried out; then, based upon the test results, the axial crash behavior of the aluminum foam-filled hat sections were analyzed.
The target of the study was to develop a mathematical model enabling analysis of the collision and, if applicable, to create a tool for the design of bonnet modifications leading to more pedestrian friendly structure.
This study examined the perceptual features of leopards (Panthera pardus) used as recognition cues by bonnet macaques (Macaca radiata) at three sites in southern India.
