The PIAT was designed in 1942 in response to the British Army's need for a more effective infantry anti-tank weapon and entered service in 1943. The PIAT was based on the spigot mortar system, and projected (launched) a 2.5 pound (1.1 kg) shaped charge bomb using a cartridge in the tail of the projectile. [5]
Diagram of PIAT ammunition. HEAT warheads were developed during World War II, from extensive research and development into shaped charge warheads. Shaped charge warheads were promoted internationally by the Swiss inventor Henry Mohaupt, who exhibited the weapon before World War II. Before 1939, Mohaupt demonstrated his invention to British and ...
The protein targeting warhead, E3 ligase, and linker must all be considered for PROTAC development. Formation of a ternary complex between the protein of interest, PROTAC, and E3 ligase may be evaluated to characterize PROTAC activity because it often leads to ubiquitination and subsequent degradation of the targeted protein.

Panzerschreck (lit. "tank's dread" or "tank's bane") was the popular name for the Raketenpanzerbüchse 54 ("Rocket Anti-armor Rifle Model 54", abbreviated to RPzB 54), an 88 mm reusable anti-tank rocket launcher developed by Nazi Germany in World War II.
The warhead was accelerated to a speed of 28 m/s (92 ft/s), had a range of about 30 m (98 ft) and an armour penetration of up to 140 mm (5 + 1 ⁄ 2 in) of plain steel. Soon a crude aiming device similar to the one used by the Panzerfaust was added to the design; it was fixed at a range of 30 m (98 ft).
The phase diagrams are shown in Figure 5. Tracking the x-intercepts in the phase diagram as r changes, there are two fixed point trajectories which intersect at the origin; this is the bifurcation point (intuitively, when the number of x-intercepts in the phase portrait changes). The left fixed point is always unstable, and the right one stable.
As the warhead and the decoy balloons may be at different temperatures, the warhead and the balloons may both be surrounded by heated shrouds that put them all at the same temperature. This defeats attempts to discriminate between decoys and warheads on the basis of temperature, which can confuse an enemy's missile defense systems.
The black walnut secretes a chemical from its roots that harms neighboring plants, an example of competitive antagonism.. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other.
