Based on the analysis of the crack trapping effect of cleavage ridges and penetration of crack front segments in an iron–silicon alloy, the distance between break-through points along a high-angle grain boundary is investigated. If the break-through points are close to each other, the crack trapping effect is dominant; otherwise, the grain boundary separation in break-through windows governs th...

Background The high cost of intrathecal morphine pump (ITMP) implantation may be the main obstacle to its use. Since July 2014, the Korean national health insurance (NHI) program began paying 50% of the ITMP implantation cost in select refractory chronic pain patients. The aims of this study were to investigate the financial break-even point and patients' satisfaction in patients with ITMP trea...

We report first clear evidence for the simultaneous presence of a low frequency break and a QPO in the power spectrum of a well known ultralumnious X-ray source (ULX) in M82 using long XMMNewton observations. The break occurs at a frequency of 34.2 −3 mHz. The QPO has a centroid at νQPO = 114.3± 1.5 mHz, a coherence Q ≡ νQPO/∆νFWHM ≃ 3.5 and an amplitude (rms) of 19% in the 2− 10 keV band. The ...

A strategy that integrates an organization's marketing goals into a cohesive whole, ideally drawn from market research, focuses on the ideal product mix in order to achieve maximum profit potential; the marketing strategy is set out as a marketing plan, a good idea, method, information, object, or service that is the end result of a process and serves as a need or want satisfier. It is usually ...
