Hexen II, by way of the Quake engine, uses OpenGL for 3D acceleration.

Whereas Doom, Doom II, and Heretic rely on lines within the maps to perform simple actions, Hexen also allows these actions to be activated via Action Code Script ( ACS ).

Some adaptations of the Latin alphabet are augmented with ligatures, such as æ in Old English and Icelandic and Ȣ in Algonquian ; by borrowings from other alphabets, such as the thorn þ in Old English and Icelandic, which came from the Futhark runes ; and by modifying existing letters, such as the eth ð of Old English and Icelandic, which is a modified d. Other alphabets only use a subset of the Latin alphabet, such as Hawaiian, and Italian, which uses the letters j, k, x, y and w only in foreign words.

* Equipment: Abu Sayyaf uses mostly grenades, bombs ( modified IED's and land mines ), machine guns, rifles, rocket launchers and other weapons have been reported.

Their design uses a fixed architecture — it requires changes in the wiring if the instruction set is modified or changed.

The approach is novel in that it uses a mostly stock aircraft with a modified landing gear " pod " that carries the engine for road propulsion.

Gene therapy, uses genetically modified viruses to deliver genes that can cure disease into humans.

Relatively new organizations also use the harp, but often modified to reflect a theme relevant to their organization, for instance ; Irish airline Ryanair uses a modified harp, and the Irish State Examinations Commission uses it with an educational theme.

* Stargate SG-1 uses a modified upper-case lambda, with a small circle above the apex, to indicate Earth.

The only remaining widespread uses of the Mach kernel are Apple's Mac OS X and its sibling iOS, which run atop a heavily modified Mach 3 kernel.

Nial uses a generalized and expressive Array Theory in its Version 4, but sacrificed some of the generality of functional model, and modified the Array Theory in the Version 6.

Perelman's proof uses a modified version of a Ricci flow program developed by Richard Hamilton.

This technique uses sequence-specific termination of a DNA synthesis reaction using modified nucleotide substrates.

In addition, movement in a diagonal plane uses modified double-stemmed arrows: A cross bar on the stem indicates that the motion is away as well up or down, and a solid dot indicates approaching motion.

To & fro movement that also goes over or under something uses modified single-stemmed arrows, with the part of the arrow representing near motion thicker than the rest.

Each effect can be modified by Advantages ( less energy expenditure, for example ) or Disadvantages ( reduced number of uses, for example ) which increase or reduce the cost of a power.

A variant of redundancy theory is the disquotational theory which uses a modified form of Tarski's schema: To say that '" P " is true ' is to say that P. A version of this theory was defended by C. J. F. Williams in his book What is Truth ?.
