Try a thorough cleaning. If that doesn't work, try different ammunition. If that doesn't work, find a gunsmith.
When it is stable. that is, all of it's electron shells are fully occupied.
An autocannon is a fully automatic projectile weapon which fires shells instead of bullets.
3/4's the same. The 152mm Sheridan main guns, used primarily in Vietnam, fired FULLY combustible shells, nothing came out of the breech after firing, except smoke. The Abram's 120mm ejects a back cap after firing.
Baby snails do not find empty shells, in fact, they are born with clear, soft shells. The shells harden as the snail consumes calcium and they start with the egg shell they hatched from. The shell grows with the snail and the inner circle of the shell is the shell the snail was born with.
I might not understand the question fully but I think it's the rising action.
Without being able to assess the patient, this question cannot be fully answered. But, my initial reaction is that NO, it does not necessarily mean that they are dying.
In "There Will Come Soft Rains" by Ray Bradbury, the initial catastrophe is a nuclear war that wipes out humanity and leaves the fully automated house standing as the only remnant of civilization. The house continues to function on its own despite the absence of its inhabitants.
Atoms whose outer electron shells contain eight electrons tend to be stable and do not easily form ionic bonds in aqueous solutions. This is because they have reached the stable configuration known as the octet rule. In most cases, atoms that form ionic bonds have outer electron shells that are not fully filled with eight electrons.
The patent process is a very long and expensive process. To fully protect your rights it is advisable to have the help of an attorney, but at least in the initial phase it is not necessary.
Noble gases have completely filled valence electrons. Helium has 2, other elements have 8
The NASDAQ went under initial testing in 1971 and was fully operational by 1972, although not quite in the same form as today. Very few firms had NASDAQ terminals in those early days.
That would be the Nobel gasses, 8A, because they have an octet of 8 electrons fully filling their valance shells so that they naturally do not react with other elements is either ionic or covalent bonding.
