a type of plastic, but I’m not sure if I’ve ever seen it. So, what is Bakelite? Is it still around? When was it invented? Let’s find out! The world’s first synthetic plastic, Bakelite, was beginning its development in 1907 and marks the beginning of the “Polymer Age” (...

It is important to mention that most of the children did not complain of headaches while playing video games. Tychsen and Foeller (2020) designed research to find out the effects of immersive VR on the visual motor function of 50 children aged 4–10, postural stability, and motion sickness ...
find it hard to believe that Hartman didn’t also think a bit about the negative impact a grand jury report might have on the Energy Department, if not the White House. The grand jurors, after all, were planning to denounce the DOE and all of government, not just for past failures but...
By deriving a generalized form for the Nernst equation, we find that a relatively small magnetic field (approximately 1 T) with a large gradient (up to 1 GT/m) can significantly change the membrane potential of the cell and thus have a significant impact on not only the properties and...
LFT = liver function test; LP = lumbar puncture; Mg = magnesium; MRI = magnetic resonance imaging; MRA = magnetic resonance angiography; MRV = magnetic resonance venogram; NAD = nothing abnormal detected; OD = once daily; OP = opening pressure; OPD = outpatient department; PCKD = polycystic...
It is not possible to buy custom made hearing aids off the shelf. If you are considering a custom made hearing aid, then seeing a hearing care professional is the next step. They will be able to determine your level of hearing loss, find the style that suits your needs, and create your...
