Magnetic resonance imaging

Magnetic therapy or magnet healing is a type of alternative medicine that have magnetic fields that generates healing powers towards a large number of diseases or conditions. These electromagnetic fields have been demonstrated to treat slow-healing fractures in the body and have shown good results towards to a few conditions. The website that has claimed to use this magnetic therapy are Skepdic.com. The claim that this complementary and alternative medicine practitioner is making goes…

Hannah Baker, from a white picket fence town with an almost perfect family, committed suicide. From being raped by a popular boy, to witnessing her friend's sexual assault, to her best friends turning their backs on her, Hannah endured countless acts of bullying, which she chronicles on 13 audio tapes that are passed around to her friends after her death. On the show, which was produced by Selena Gomez, we witness Hannah's friend, Clay Jensen, helplessly wish he had known what she was facing, so…

When a magnet is in motion near a non-magnetic conductor such as copper and aluminium eddy currents are induced in the conductor, causing a dissipative force called magnetic braking force, or a change in magnetic flux (figure 2). This force is dependent on: The size and shape of the conductor and magnet The strength of the magnet (μ) The conductors conductivity (σ_c) The distance between the conductive surface and the magnet (d) The velocity of the magnet (v) According to Faraday’s law,…

high-speed transport known as a hyperloop. Perhaps a more common use that is taken for granted is the magnetic…

They’ll use a nail and a battery to create a magnetic field. It’ll turn the nail into a magnet. Students should be sure to write down their observations throughout the experiment. Students will wrap the center portion of the wire around the nail 10 times so that it forms a coil. They should have extra…

The mini torsion device that will be designed for this senior design project will apply a torsional load to a small cylindrical sample with a diameter of 5 mm or 6 mm. The device will need to fit under an optical microscope and will not be able to exceed the weight limits of the sample stage on the optical microscope so that Raman microscopy can be performed on the sample while it is under a torsional load. The device will also need to collect data and calculate the angle of twist of the sample.…

using variable frequency eddy current sorter (VFECS) prototype to separate different nonferrous metal and alloy of size smaller than 1 inches. VEFECS is a solid state technology which operates at variable high frequency range between 1 – 10 KHz. The magnetic field frequency plays an important role in sorting of different nonferrous metals and alloys from each…

I want my Privacy In decades, there have been many advances in the technology industry. Undoubtfully, one of the important advances has been the internet. In "Job Candidates and Facebook ", Wei Du writes about the best-qualified candidate for the position. Information people put on social networking sites can easily be found by anybody worldwide. In "Gone with the Window," Dorothy Nixon focuses more on the personal vs. the business side, how social media can reveal too much about a person 's…

Stray current corrosion: Stray current is the current which occurs when conductors are placed between high magnetic or electric fields. Presence of stray currents over the PCB surface can generate corrosion problems. The below figure 5 shows severe corrosion damage to micro wave module for 24 GHz. This equipment is built in controlled conditions where water condensation is possible. After few hours of use, severe corrosion was seen on the surface. Figure 5. Stray current corrosion of a micro…

Rotor and touchdown bearing models Fig. 1 features the case study of the high-speed rotor. The photo was taken after manufacturing of the electric motor part, when the rotor was carried to the laboratory for an experimental modal analysis. During normal operation, the rotor is supported by AMBs. In the dropdown event, the rotor is in contact with touchdown bearings at both ends of the rotor. Fig. 1. Rotor under investigation. In this work, the finite element model of the rotor employs…
