The conditions of diffusional cavity nucleation in submicrocrystalline materials processed by the methods intensive plastic deformation (equal-channel angular pressing, multiaxial forging, high pressure torsion, etc.) are analyzed. To date, question mechanism cavities such remains debatable due to fact that processing is carried out at hydrostatic pressures prevent appearance pores. possibility...

Triple arrays are considered in which 10 symbols each appear 3 times in a 5 × 6 arrangement of symbols. These triple arrays fall into seven isomorphism classes. The orders of the automorphism groups of the arrays in these classes are 60, 12, 12, 6, 4, 3 and 3, respectively. © 2005 Elsevier B.V. All rights reserved.

This research paper describes key information technology (IT) project management activities in terms of project scope, time, and cost management, namely the triple constraint. The authors contend that the ability to properly manage and execute these activities are the quintessential components that oftentimes drives whether projects succeed or fail. The literature shows that IT projects have a ...

this study focused on triple-negative breast cancer (tnbc) that is characterized by the lack of expression of estrogen receptor (er), progesterone receptor (pr), and human epidermal growth factor receptor 2 (her-2). the primary goal of this study was to describe the relation between triple-negative receptor status and survival. this is the first study about triple-negative breast cancer in our ...

peripherally inserted venous ports fracture with embolization in patients who received chemotherapy is a serious and rare complication,and few cases have been reported in children. we report a successful endovascular technique using a snare for retrieving broken peripherally inserted venous ports in a child for chemotherapy. catheter fragments may cause complications such as cardiac perforation...

Abstract Double-diffusive systems, such as thermosolutal convection, in which the density depends on two components that diffuse at different rates, are prone to both steady and oscillatory instabilities. Such systems can evolve into layered states, components, also density, adopt a “staircase” profile. Turbulent transport is enhanced significantly state. Here we exploit an analogy between magn...
