Aluminium oxynitride (marketed under the name ALON by Surmet Corporation [3]) is a transparent ceramic composed of aluminium, oxygen and nitrogen.Aluminium oxynitride is optically transparent (≥80% for 2 mm thickness) in the near-ultraviolet, visible, and mid-wave-infrared regions of the electromagnetic spectrum.
The VS-50AR is an electronically fuzed version of the mine which contains an integral mercury tilt switch, that operates as an anti-handling device. The VS-50AR has a dummy pressure plate on top and its external appearance is very similar to the VS-50, which has obvious implications for demining personnel.
There have been many advancements made in ergonomics, blast resistant material and infection prevention over the last couple decades. Currently there are many options available for dismounted troops to protect them from all types of danger. Below are a few of the currently-fielded systems and what is to come.
A soldier examines two inverted VS-1.6 blast-resistant anti-tank landmines. Cut-away view of a VS-MK2 blast-resistant anti-personnel mine. A blast resistant mine is a landmine (intended for anti-tank or anti-personnel purposes) with a fuze which is designed to be insensitive to the shock wave from a nearby explosion.
The MAT/6 is an Italian circular synthetic resin-cased minimum metal blast resistant anti-tank blast mine. It uses a pneumatic fuze which is resistant to shock and blast, and is also claimed to be resistant to mine flails and mine rollers. The mine's plastic case is waterproof, and it can be laid in shallow water.
Slate is particularly suitable as a roofing material as it has an extremely low water absorption index of less than 0.4%, making the material resistant to frost damage. [18] Natural slate, which requires only minimal processing, has an embodied energy that compares favorably with other roofing materials. [ 19 ]
Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. It is important to note, the oxide form may or may not be present once the molten slag solidifies and forms amorphous and crystalline components.
A minimum metal mine is a land mine that is designed to use the smallest amount of metal possible in its construction. Typically, the only metal components are located inside the fuze mechanism which triggers detonation. [1] Both minimum metal anti-tank and anti-personnel mines exist. Some designs contain virtually no metal at all, e.g., less ...
