Some cartridges, like the .470 Capstick, have what is known as a "ghost shoulder" which has a very slightly protruding shoulder, and can be viewed as a something between a bottleneck and straight-walled case. A ghost shoulder, rather than a continuous taper on the case wall, helps the cartridge to line up concentrically with the bore axis ...
IPS (in-plane switching) is a screen technology for liquid-crystal displays (LCDs). In IPS, a layer of liquid crystals is sandwiched between two glass surfaces. The liquid crystal molecules are aligned parallel to those surfaces in predetermined directions (in-plane). The molecules are reoriented by an applied electric field, while remaining ...
Screen-door effects are more noticeable than LCD when up close, or on larger sizes. [53] New models are no longer produced. Colored sub-pixels may age at different rates, leading to a color shift, although some models will scan pixels to even out wear and prevent this shift. [54] Sensitive to UV light from direct sunlight.
Burn-in on a monitor, when severe as in this "please wait" message, is visible even when the monitor is switched off. Screen burn-in, image burn-in, ghost image, or shadow image, is a permanent discoloration of areas on an electronic visual display such as a cathode-ray tube (CRT) in an older computer monitor or television set.
In engineering, a bottleneck is a phenomenon by which the performance or capacity of an entire system is severely limited by a single component. The component is sometimes called a bottleneck point. The term is metaphorically derived from the neck of a bottle, where the flow speed of the liquid is limited by its neck.
Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
P.O. Ackley was a notable gunsmith famous for developing wildcat cartridges from parent cartridges like the 30-06 Springfield. For many of the wildcats listed above, and several of standardized commercial chamberings based on the 30-06 cartridge, there are "Ackley Improved" versions with sharper shoulders increasing case capacity.

The screen-door effect (SDE) is a visual artifact of displays, where the fine lines separating pixels (or subpixels) become visible in the displayed image. This effect can be seen in digital projector images and regular displays under magnification or at close range, but the increases in display resolutions have made this much less significant.
