For some species, such as mouse, a drill is used to pierce the outer layers of the oocyte.

Vernam's system was a cipher that combined a message with a key read from a punched tape.

However, complex messages such as SOAP messages require a parser and a string transformer for them to exhibit intended meanings.

A more prominent secondary winding, with vastly more turns of thinner wire than the primary, was positioned to intercept some of the magnetic field of the primary.

On these machines, the normal development process involved the use of a Friden Flexowriter to prepare source code offline on a continuous strip of punched paper tape.

Punched tape or perforated paper tape is a form of data storage, consisting of a long strip of paper in which holes are punched to store data.

In the earlier period between 3.8 and 4.1 Ga, changes in the orbits of the gas giant planets may have caused a late heavy bombardment by asteroids that pockmarked the Moon and the other inner planets (Mercury, Mars, and presumably Earth and Venus).

An older means of binding is to have the sheets stapled to the cardboard along the top of the tablet there is a line of perforated holes across every page just below the top edge from which any page may be torn off.

James Watson and Francis Crick determined the structure of DNA in 1953, using the X ray crystallography work of Rosalind Franklin and Maurice Wilkins that indicated DNA had a helical structure (i.e., shaped like a corkscrew).

In these miniature circuit breakers, the current is run through a solenoid, and, in the event of excess current flow, the magnetic pull of the solenoid is sufficient to force open the circuit breaker's contacts (often indirectly through a tripping mechanism).
