MR Artifacts, Safety, and Quality Control

Electrical and electronic components could gradually deteriorate, and if the deterioration goes undetected, it could lead to substantial imager downtime. Even a seemingly benign undertaking such as upgrading of software might change the characteristics of the imaging system in ways that could go undetected unless appropriate testing is performed before and after the upgrade.

Fortescue Metals Group (FMG) Case Study

The visit in November 2018 suggested that the economic outlook would continue to deteriorate over the winter. This would likely force the Chinese government to stimulate the economy to reach its 'stable growth' goal through once again pulling the levers of infrastructure and housing, but in a more targeted and controlled manner.

Q A: Radioactivity and Magnetism

No, not really; radioactivity and magnetism are rather different things. That having been said, radioactivity and magnetism do show up together in various contexts, and there are some things which are interesting to talk about. Some forms of radioactivity (alpha and Get price

Iron(II) sulfate

Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula FeSO4xH2O. These compounds exist most commonly as the heptahydrate (x = 7) but are known for several values of x. The hydrated form is used medically to treat iron deficiency, and also for industrial applications. Known since Get price

Noise Reduction Windows that Save You Money on Energy

Many windows are sealed with caulking and stripping intended to protect against drafts, but even these will deteriorate over time. In some cases, replacing the calking is enough, but other times it's best to insulate your existing windows with the Magnetite double glazed noise reduction and energy-saving storm window system.

Do magnets ever lose their magnetism?

Do magnets ever lose their magnetism? Asked by: Kevin H. Answer Yes, it is possible for a permanent magnet to lose its magnetism. There are three common ways for this to occur: 1) Via heat: ferromagnet materials will lose their magnetism if heated above a point known as the Curie temperature. Get price
