The color correction of the SCT is on par with a good ED triplet. For example, the Astro Tech 130mm Apo uses an ED element and the polychromatic Sthrehl is about .95, which is quite excellent, but observers using this scope report seeing a very tiny fringe on blue, and this shows i...
Typical uses Alnico Iron (50%+), aluminum (8–12%), nickel (15–25%), cobalt (5–40%), plus other metals such as copper and titanium. Magnets in loudspeakers and pickups in electric guitars. Amalgam Mercury (45–55%), plus silver, tin, copper, and zinc. Dental fillings. Babbitt...

Millimeters of mercury are used as units for blood pressure measurements, even in countries like the USA and the UK, where inches are used for measuring length. Digital blood pressure meter or sphygmomanometer A Pythagorean cup is an interesting device, which uses the principles of hydrostatic ...
I don’t care if you’re Barry White or Rammstein. #3 is the MOST IMPORTANT ELEMENT. What sucks is if you are a really good singer, chances are you Love Frank Sinatra and Luther Vandross as much as you do Freddie Mercury and Luciano Pavorotti. If you’re a music lover; you Love ...
A TICM II thermal imaging system uses a cryogenically cooled eight element Cadmium-Mercury-Telluride (CMT) SPRITE (Signal PRocessing In The Element) detector which is mechanically scanned over the thermal scene to be viewed. The TALYTHERM system is based on a modified TICM II thermal image ...
AMA 254 uses an element-specific lamp that emits light at a wavelength of 253.7 nm, and a silicon UV diode detector for mercury quantitation. Samples were weighed (50 to 100 mg) with 0.1 mg readability with the use of an electronic analytical balance (model Radwag E425). Then, the ...
Heavy metals found in the soil in the form of traces are insignificant chemical elements in terms of quantity, but they are necessary as micronutrients for plants [1,2,3,4,5,6,7]. Heavy metal behavior in soils varies widely depending on the element and type of soil, and these distinction...
