** vertical opening on the upper front side with buttons or zipper

** On some maps intended for wilderness or navigational use, including the topographic maps of the U. S. Geological Survey ( USGS ), a diagram shows the relationship between magnetic north in the area concerned ( with an arrow marked " MN ") and true north ( a vertical line with a five-pointed star at its top ), with a label near the angle between the MN arrow and the vertical line, stating the size of the declination and of that angle, in degrees, mils, or both.

** Milling machines, horizontal, vertical, and boring mills

** Turning machines, engine lathe, turret lathe, vertical turret lathe, vertical boring mill

Model 1910 ( Mk III ) was made with a totally different bolt head ; instead of having the solid bolt lugs travel in a vertical position and lock in a horizontal position, like for the Mk II and Mk II ** ( see illustration ), Ross turned it 90 degrees so it travels in an horizontal position and locks vertically.

** Jean-Baptiste Lamarck publishes Recherches sur l ' Organisation des Corps Vivants, proposing that all life is organized in a vertical chain of progressive complexity.

** Hydrostatic instability or static instability / vertical instability ( parcel instability ), thermodynamic instability ( atmospheric thermodynamics )

** The worlds first vertical launch of a manned rocket takes place when the German Bachem Ba 349 Natter rocket fighter makes its first manned launch under rocket power.

** vertical electrical sounding ( VES ), see Schlumberger brothers

** an Aerobatic maneuver, rotation around the vertical axis

** On the wave's " ramp ", the magnetic field produced by the deflection yoke drags the electron beam across the face of the CRT, creating a scan line.

** The voltage applied to the deflection yoke is adjusted by various means ( transformers, capacitors, center-tapped windings ) so that the half-way voltage on the sawtooth's cliff is at the zero mark, meaning that a negative voltage will cause deflection in one direction, and a positive voltage deflection in the other ; thus, a center-mounted deflection yoke can use the whole screen area to depict a trace.

** Second moment of area, a property of an object related to its resistance to bending and deflection

** Rigidity ( electromagnetism ), the resistance of a charged particle to deflection by a magnetic field

** Romano-Germanic subgroup ( comprising those legal systems where legal science was formulated according to Roman Law-see also Civil law ( legal system ))

** Dispersion relation, the mathematical description of dispersion in a system

** using another lower-level device driver ( e. g. file system drivers using disk drivers )
