The Deathclaw Gauntlet aka: Murder Glove. A staple of the crafting bench in Fallout 3, these days the Deathclaw Gauntlet is a little bit harder to come by for the average Wasteland citizen. But if you follow these steps you can get your hands on one for the mere price of killing a Deathclaw.
An isobar refers to all of the nuclides of all elements that have a particular atomic mass. For example, helium-6 is one of the many isotopes of helium. The isobars of helium-6 are hydrogen-6, lithium-6, beryllium-6, and boron-6. (Note, hydrogen-6, beryllium-6, and boron-6 are unbelievably short-lived).
Points of equal pressure can be connected with a line, and these are the isobars. They are commonly shown on a map in increments of four millibars. Isobars drawn on a map this way make it visually easier for a meteorologist to interpret. One way to think about an isobar map is like it's showing elevation. Areas of high pressure are like mountains, and areas of low pressure are like valleys.
