Alpha helix and beta pleated sheets both are held together with H bonds between carbonyl O and amino N. Alpha helix specifies with residues bind. Beta pleated sheets can happen between any 2 residues.
Stabilized by hydrogen bonds, hydrogen bonding between amides groups
Polypeptide secondary structures.
Beta sheets consist of beta strandsconnected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet.
Secondary structure
A regular element of secondary structure in proteins, in which two or more extended strands of the polypeptide chain lie side by side (running either parallel or antiparallel), held together by a regular array of hydrogen bonds between backbone NH and C=O groups, to form a ridged planar surface. The amino-acid side chains alternately face to opposite sides of the sheet.
The difference is the position of the double bond
The difference between a beta plus and beta minus particle is the electrical charge. The charges are equal, but opposite. The beta minus particle is an electron with a negative charge, while the beta plus particle is an anti-electron or positron with a positive charge.
A beta-folded sheet is a secondary structure of a protein, which is the next level of molecular organization above the primary structure. It is formed by hydrogen bonding between adjacent segments of a polypeptide chain, creating a flat and elongated sheet-like structure.

A beta barrel is a large beta sheet which twists and coils to form a closed structure in which the first strand is hydrogen-bonded to the last.

"beta burns" are shallow surface burns
Beta particles are not stopped by a paper sheet.

The Beta was used to test the game for Bungie.
A brief explanation of the difference between beta and alpha test is that alpha test is usually in-house and is part of basic development. Beta test is right before product release and typically includes customer input.
