Positive design

Applying this rule, the preceding dyes are written (3-methyl-4-phenyl-thiazole-2)(3-methylthiazole-2)methine cyanine iodide (3a) and (3-methyl-4-phenylthiazole-2)( l-methylquinoline-2)methine cyanine iodide (4), respectively. Any substituent in the chain is named and its position designated by a, ft or y, for example, (3-methyl-4-phenylthia2ole-2)(3-methylthiazole-2)-/S-methyltrimethine cyanine iodide (3b). 

Equipment which may be exposed to vacuum by any single process contingency should be designed for vacuum. In many cases, equipment with a substantial positive design pressure is capable of withstanding full vacuum, but the design should be checked. As an alternative to designing for vacuum, means... 

Bombing of U.S. Marine Barracks, Beirut — On April 18, 1983, a vehicle driven by a member of the Islamic Jihad crashed into the outer wall of the U.S. Embassy in Beirut, killing 67 people, 17 of whom comprised the majority of Central Intelligence Agency (CIA) staff in Lebanon. In retaliation, the U.S. Navy bombarded terrorist positions designed to aid the Lebanese army in Beirut. In response, on October 23,1983, the Islamic Jihad fitted two trucks with 12,000 pounds of explosives and sent them on a suicide mission. The trucks passed the lax security at the U.S. Marine guardhouse and crashed into a wall of a four-story concrete barrack. All 241 marines and 58 French soldiers inside were killed in the explosion. 

Figure 5. A DNA molecule whose helix axes have the connectivity of a cube. The molecule shown consists of six cyclic strands that have been catenated together in this particular arrangement. They are labeled by the first letters of their positional designations, Up, Down, Front, Back, Left, and Right. Each edge contains 20 nucleotide pairs of DNA, so we expect that their lengths will be approximately 68 A. All of the twisting has been shown in the middle of the edges for clarity, but the DNA is base-paired from vertex to vertex. From model building, the axis-to-axis distance across a square face seems to be approximately 100 A, with a volume (in a cubic configuration) of approximately 1760 nm3 when the cube is folded as shown.

The second "letter" of the chemical name is the actual substituent or substituents found at the positions designated by the numbers above. There are only three substituents to be considered in this chemical alphabetical sequence they are, in order ... 

Ba(2), Ba(3), and Ba(4) refined to 1.9(1), 1.2(1), 2.0(5) and 0.8(5), respectively. Because the Ba(3) and Ba(4) positions had nearly become coincident, they were represented as 3 Ba + ions at an intermediate position, designated Ba(3). The occupancies at Ba(l) and Ba(2) were fixed at 2 and 1 in further refinement. A subsequent difference Fourier synthesis served to locate the water molecules at 0(5). Numerous attempts to locate additional water molecules failed. 

On this basis, coiled-coil designers often place oppositely charged residues Lys and Glu at complementary g and e sites to direct the assemblies that they are targeting (positive design), and make similar potential interactions in alternative structures repulsive (negative design). 

Names of branched-chain unsaturated aliphatic hydrocarbons (IUPAC rules) are formed from the name of the longest fundamental chain present in a formula and the names of the side chains with proper position designations. The resulting names... 

Position designations must be added to identify completely the radicals. Names apply whether point of attachment is on the ring or on a numbered substituent. 

In researching resistance on rubber abrasion, a Martindale tester is used for com-parasions of various rubber samples. Five types of rubbers have been tested in five cycles on four tester positions. Design of experiment for five rubber types and five test cycles is the Youdens square shown in Table 2.85... 

In the making of snuff bottles and other small items, gourds and other fruits can be placed in wooden or metal molds while they were still growing. The inside of these molds are carved in reverse so that the positive designs will be impressed into the adult fruit. Objects created in this way were often lacquered or decorated after they were removed from the mold. Other fruits molded in this way include tangerines, oranges, and lemons. 

These symbols are often combined with coordination numbers and position designations for stereochemical descriptors (e.g., OC-6-11 ).

As a point of reference, typical healthy human lungs can develop 50 or more inches (12.5 kPa gauge) of water pressure. Compare the pressure that lungs can supply to the typical 10-inch (2.5 kPa gauge) water pressure positive design pressure of low-pressure... 

Figure 3 The widening of the energy gap between the native state and the misfolded structures during an increase in the environmental temperature. Positive design provides the lowering of the native state energy, whereas negative design contributes to the increase of the energy of misfolded structures.

The permeate is continuously withdrawn through the membrane from the feed sueam. The fluid velocity, pressure and species concentrations on both sides of the membrane and permeate flux are made complex by the reaction and the suction of the permeate stream and all of them depend on the position, design configurations and operating conditions in the membrane reactor. In other words, the Navier-Stokes equations, the convective diffusion equations of species and the reaction kinetics equations are coupled. The transport equations are usually coupled through the concentration-dependent membrane flux and species concentration gradients at the membrane wall. As shown in Chapter 10, for all the available membrane reactor models, the hydrodynamics is assumed to follow prescribed velocity and sometimes pressure drop equations. This makes the species transport and kinetics equations decoupled and renders the solution of... 

The Universal Decimal Classification (UDC) is an effort to ride both horses at once. It succeeds within a fixed path directed from Brussels, but not in the struggle to serve academic, industrial, and military needs for bibliographic control. Though the decimal classification has shifted from positioning books to positioning index cards, it is still a position-designating system with only limited applicability to the infinitely variable demands of subject searching.
