Confrontation visual field testing is an important part of a routine ophthalmological or neurological examination. It can be used for rapid and gross assessment of large-scale visual field problems due to ophthalmological or neurological diseases, such as homonymous and heteronymous hemianopias, quadranopsia, altitudinal visual loss, central/centrocecal scotoma etc. [1] [2] Test using a red ...
An examiner presents a test light of variable size and intensity. The light may move towards the center from the perimeter (kinetic perimetry), or it may remain in one location (static perimetry). The Goldmann method is able to test the entire range of peripheral vision and has been used for years to follow vision changes in glaucoma patients. [3]

Sample from a kinetic energy weapon test. A piece of polycarbonate plastic weighing 7 grams ( 1 ⁄ 4 oz) was fired at an aluminium block at 7 km/s (23,000 ft/s), giving it muzzle energy of 171,500 J (126,500 ft⋅lbf); a typical bullet has muzzle energy of a few thousand joules, with the enormous .950 JDJ reaching 20,000 J (15,000 ft⋅lbf).
By the time the test program was finished it was obvious the Army was going to cancel LOSAT after the low-rate initial production (LRIP) batch of about 435 missiles was delivered. [3] By this point the Army had already started work on a system known as the Compact Kinetic Energy Missile (or CKEM), based on the LOSAT concepts but smaller and ...

The Avangard (Russian: Авангард, "Vanguard"; previously known as Objekt 4202, Yu-71 and Yu-74) is a Russian hypersonic glide vehicle (HGV). It can be carried as a multiple independently targetable reentry vehicle (MIRV) payload of heavy intercontinental ballistic missiles (ICBMs), such as the UR-100UTTKh, [6] [7] R-36M2 and RS-28 Sarmat.
