Connections, drawing

The words in a math problem suggest how different parts of the situation are connected — or not connected. Drawing a picture helps to make the connections and, often, suggests how to proceed with a solution.

Biochemical Connections Draw the interactions between bases that make triple-helical DNA possible. 

Connection drawings—documents the electrical connections of an installation or of its component devices or parts.

Hash coding is an established method in computer science, e.g., in registration procedures [94, 95. In chemoinformatics the structure input occurs as a sequence of characters (names) or numbers (which may also be obtained, e.g., from a connection table (see Section 2.4) by conversion of a structure drawing). Both names and numbers may be quite large and may not be usable as an address... 

A molecule editor can draw a chemical structure and save it, for example as a Molfile. Although it is possible to include stereochemical properties in the drawing as wedges and hashed bonds, or even to assign a stereocenter/stereogroup with its identifiers R/S or E/Z), the connection table of the Molfile only represents the constitution (topology) of the molecule. 

The molecular editor consists of a java applet that is embedded in the HTML document. It encodes the drawing into a connection table in inol-format, which is sent to the web server. 

There are a number of different ways that the molecular graph can be conununicated between the computer and the end-user. One common representation is the connection table, of which there are various flavours, but most provide information about the atoms present in the molecule and their connectivity. The most basic connection tables simply indicate the atomic number of each atom and which atoms form each bond others may include information about the atom hybridisation state and the bond order. Hydrogens may be included or they may be imphed. In addition, information about the atomic coordinates (for the standard two-dimensional chemical drawing or for the three-dimensional conformation) can be included. The connection table for acetic acid in one of the most popular formats, the Molecular Design mol format [Dalby et al. 1992], is shown in Figure 12.3. 

Drawing a stream of air over the surface by inserting a tube, connected to a water pump, above the mixture. 

Antithetical connections (the reversal of synthetic cleavages) and rearrangements are indicated by a con or rcarr on the double-lined arrow. Here it is always practical to draw right away the reagents instead of synthons. A plausible reaction mechanism may, of course, always be indicated. 

To complete an approximate sketch of the titration curve, we draw separate straight lines through the two points before and after the equivalence point (Figure 9.35e). Finally, a smooth curve is drawn to connect the three straight-line segments (Figure 9.35f). 

Local Site Condition Evaluation. In addition to visiting the site, drawing up a contour map and geology reports, acquiring sod-bearing information, and a knowledge of boundaries, setbacks, local requirements, utdity tie-in locations, sewer connections, access to roadways, pipelines, radroads, etc, may be needed to make a fliU assessment. 

To receive a filing date, an appHcation made on the basis of intent-to-use must include "a claim of bona fide intention to use the mark in commerce," a description of the goods upon or in connection with which the appHcant has the intention to use the mark and the mode and manner in which it is to be used, and a statement that the appHcant is entitled to use the mark and that, to the best of the appHcant s knowledge, no other person or entity has the right to use the mark or a confusingly similar mark. A drawing of the mark must be submitted with the appHcation. 

The mix point, = 0.0673, falls on a straight line connecting x and The extract composition is then determined hy drawing a straight line from x,-throiigh Zm until the line intersects the extract line at the final extract composition, i/e = 0.084. The delta point is then found at the intersection of two lines. One line connects the feed and extract compositions x and y. The other line connects the raffinate and solvent compositions x,- and y. ... 

Locating now in their respec tive scales on Nomograph 4 the design factor (from Nomograph 3) and the calculated equivalent lengm, draw an extended straight line to intersect the pivot line in the center. Now connect this point in the pivot line with the solids-ratio scale (from Nomograph 2), and read the system ressure loss. 

In a fixed construction, all the feeders in the switchboard, feeding the various load points, are securely mounted in the assembly and rigidly connected to the main bus. In the event of a fault in one feeder on the bus side, a shutdown of the entire switchboard may be required. A process industry or critical loads can ill afford such an arrangement. However, since this is the most cost-effective switchboard, it is also the most common type and is used extensively. It also suits all applications, except a process industry or critical loads, which may not be able to afford a total shutdown or prolonged downtime in the event of a fault. In such cases a draw-out type switchboard will prove to be a better choice as discussed below. A fixed-type construction may further be classified as follows.
