Directed assembly

A tenfold increase of the intensity may be obtained at the cost of a somewhat reduced thermal stability by omitting the draft shield and mounting the shutter and lamp assembly directly on top of the sample holder enclosure block. Since the heat production of the fluorescent lamp is very small the whole irradiation equipment could be mounted within the standard glove-box. 

Fuze, MTSQ M501A1 (or M501). This fuze is similar to M500 except that it has no boosters and its threaded base is assembled directly into the projectile. The fuze is intended for use in the 155-mm Howitzer Ml, M1A1 or M48 (Ref 52, pp 5-74 5-75)... 

In man-made fibres, any stretching will irreversibly alter the crystallinity and there is no control of the lateral size of polymer crystals. Semicrystalline polymer networks typically consist of platelet type crystals whose width exceeds their thickness by several order of magnitudes because only the thickness is controlled by the chain folding [61]. In contrast to synthetic fibres, spider silk does not need any mechanical treatment by external forces the constituents self-assemble directly during the spinning-process. These examples clearly demonstrate the need for more detailed control of the mesoscopic structures for further development of man-made materials. 

Stable colloids of nanometer-sized lamellar manganese oxides have been prepared by intercalation and self-assembly direct reduction methods. The structures, particle sizes, and optical properties of the materials have been described. Organic amine/ammonium species (TAA and DA) were used to intercalate birnessite H-OL-1 to prepare TAA-OL-1. Many kinds of structures and their formation processes were also described. The effects of organic ammonium cations and organic amines on the preparation of the manganese oxides were studied systematically. 

Intercalation and self-assembly direct reduction methods were described to prepare TAA-OL-1. Organic amine/ammonium species (TAA and DA) were used to intercalate bimessite H-OL-1. Many kinds of structures were described and their formation processes were described. 

A number of related catenanes, including systems assembled directly from commercially available precursors and a system based on sulfonamide linkages, have also been described. 

DNA polymerases catalyze the step-by-step addition of deoxyribonucleotide units to a DNA chain (Figure 5 21). Importantly, the new DNA chain is assembled directly on a preexisting DNA template. The reaction catalyzed, in its simplest form, is ... 

The RADACK (contraction of RADiation-induced attACK) model, that we have developed [9,10], accounts for the experimentally determined probabilities of radiolytic damages caused by the OH radical attack in all forms of DNA (B [11], Z [12], triplex [13], quadruplex [14]), in DNA-protein complexes [15] and has the potential to predict radiolytic attack probabilities in other molecules or assemblies. Direct ionisation effects are not taken into account. The determination of relative probabilities of reaction ofthe target with the OH radicals takes into account two factors 1) the accessibility of the reactive sites of the target since it uses the exact tridimensional structure of the macromolecule or assembly as determined by NMR, crystallography or as built up by molecular modelling, and 2) the chemical reactivity of the residues (nucleotides or amino-acids). 

Use a match to light the pecan. Quickly swing the water-filled soft-drink can assembly directly over the combustion can, allowing a small separation between the two cans. 

Although there are still no reliable ways of predicting the structure, this has not been for want of trying. There are currently two approaches that involve the use of bond valences. In the first, bond valences are used to assess the quality of, and improve, randomly generated trial structures in the second the structure is assembled directly using the crystal chemical rules of the bond valence model.

This is the second condition for self-assembly, namely the condition of stability of the self-assembling macrocycle over the acyclic oligomers. This is an important relation showing that the required driving force for self-assembly directly depends on the number of monomer units constituting the cyclic...

In practice, it is often useful to evaluate the influence of moisture on a fiber assembly directly. This is particularly meaningful when the performance of the product depends on several mechanical properties (such as transverse compression, tensile, bending, and torsional characteristics, etc.) of the constituent fibers at once. 

All of these methods identify mutations that disturb the formation of spores severely, showing defects in either entry into meiosis, meiotic chromosome behavior, or spore morphogenesis (and, for the ether test, germination). As with any good mutant hunt, secondary screens to identify mutants specifically defective in a particular aspect of meiosis must be established. For instance, ether sensitivity could reflect spore inviability due to chromosome missegregation or could be due to defects in spore wall assembly. Direct spore dissection of candidate mutants can distinguish between these two possibilities. 

Selective membrane is assembled directly inside the reaction environment, so that the hydrogen produced by reactions is immediately removed. Such a configuration is called Membrane Reactor (MR) [9-13].
