Abstract:
In order to improve the structure mechanics performance of assembly body of conical pick, the finite element method was taken to analyse assembly body of conical pick based on rock cutting theory, and the distortion law of stress and displacement of carbide tip, pick arbor and pick holder were obtained. The results show that the maximum stress appearing in pick carbide tip and its weld site is 371MPa, maximum stress of pick holder appearing in its weld site is 157MPa. Consequently, the quality of the weld should be ensured in processing and manufacturing or welding installation to reduce the p

ABSTRACTTo better characterize the assembly of the HIV-1 core, we have used electron cryotomography (ECT) to image infected cells and the viral particles cryopreserved next to them. We observed progressive stages of virus assembly and egress, including flower-like flat Gag lattice assemblies, hemispherical budding profiles, and virus buds linked to the plasma membrane via a thin membrane neck. The population of budded viral particles contains immature, maturation-intermediate, and mature core morphologies. Structural characteristics of the maturation intermediates suggest that the core assembl

Abstract:
The HIV capsid self-assembles a protective conical shell that simultaneously prevents host sensing whilst permitting the import of nucleotides to drive DNA synthesis. This is accomplished through the construction of dynamic, highly charged pores at the centre of each capsid multimer. The clustering of charges required for dNTP import is strongly destabilising and it is proposed that HIV uses the metabolite IP6 to coordinate the pore during assembly. Here we have investigated the role of inositol phosphates in coordinating a ring of positively charged lysine residues (K25) that forms at the bas

This research presents a continuous element model for solving vibration problems of FG stepped truncated conical shells having various material properties and surrounded by Pasternak foundations. Based on the First Order Shear Deformation Theory (FSDT) and the equations of the FGM conical shells, the dynamic stiffness matrix is obtained for each segment of the shell having constant thickness. The interesting assembly procedure of continuous element method (CEM) is employed for joining those segments in order to analyze the dynamic behavior of the FG stepped truncated conical shells an assembly

An accurate modal analysis of the stepped rotor assembly is significant in the design process of rotors. The transfer matrix method (TMM) is widely used in the modal analysis of the rotor. However, the influences of the step and the assembling modes are not considered in the traditional TMM. In this paper, a modified transfer matrix method is presented for the modal calculation of the rotor in the turbomolecular pump. The stiffness reduction of stepped segments and the effect of assembled components are considered in this modified method. First of all, the traditional transfer matrix model is

Abstract:
The HIV-1 capsid is one of virology’s most iconic structures, yet how it assembles has long remained elusive. Remarkably, the capsid is made from just a single protein, CA, which forms a lattice of ~250 hexamers and exactly 12 pentamers. Conical capsids form inside budded virions during maturation, but early efforts to reproduce this in vitro resulted instead in open-ended tubes with a purely hexameric lattice. The missing component in capsid assembly was finally identified as the metabolite inositol hexakisphosphate (IP6). Simply mixing soluble CA protein with IP6 is sufficient to drive the s

Because its tooth thickness varies with the face-width, the contact pattern of a conical gear pair is point contact. Therefore, the flank surface would be failed due to a large contact stress under heavy loading. Some research works have been proposed to solve this problem. One of the methods is flank modification on conical gears to lower the contact stress. The conventional method is applied with a circular path
