In a hydrocarbon molecule with all carbon atoms making up the backbone in a tetrahedral molecular geometry, the zigzag backbone is in the paper plane (chemical bonds depicted as solid line segments) with the substituents either sticking out of the paper toward the viewer (chemical bonds depicted as solid wedges) or away from the viewer ...
[3] [4] This diagram style is an alternative to a sawhorse projection, which views a carbon–carbon bond from an oblique angle, or a wedge-and-dash style, such as a Natta projection. These other styles can indicate the bonding and stereochemistry , but not as much conformational detail.
The wedge product was introduced originally as an algebraic construction used in geometry to study areas, volumes, and their higher-dimensional analogues: the magnitude of a 2-blade is the area of the parallelogram defined by and , and, more generally, the magnitude of a -blade is the (hyper)volume of the parallelotope defined by the ...
Character race is a descriptor used to describe the various sapient species and beings that make up the setting in modern fantasy and science fiction. In many tabletop role-playing games and video games , players may choose to be one of these creatures when creating their player character (PC) or encounter them as a non-player character (NPC).
These fragments were then used as building blocks in the structure generator. This structure generator was part of a CASE system, ESESOC. [23] Breadth-first search generation. Molecular structure generation is explained step by step. Starting from a set of atoms, bonds are added between atom pairs until reaching saturated structures.
In addition, their skin resembles polished obsidian, and their hair is snow-white or silver. Their eyes are almost inevitably red, gleaming with the hatred for their surface dwelling cousins. In 4th edition, the drow are a separate race rather than an elf subrace. Dark Elves (Ssri-Tel'Quessir) Recently returned into the fold of the true elven race.
The mechanical advantage or MA of a wedge can be calculated by dividing the height of the wedge by the wedge's width: [1] M A = L e n g t h W i d t h {\displaystyle {\rm {MA={Length \over Width}}}} The more acute , or narrow, the angle of a wedge, the greater the ratio of the length of its slope to its width, and thus the more mechanical ...
The AD&D 2nd Edition Monstrous Manual (1993) introduced Urds, a race similar to kobolds with batlike wings. [10] Later editions of the game emphasized more draconic aspects, and suggest that kobolds are biologically related to dragons, and view them as an object of worship and servitude. [11]
