Double length

One hundred and fifty grams (1.8 moles) of pure cyanoacet-amide (Org. Syn 9, 36) is thoroughly mixed in a large (20-cm.) mortar with 150 g. (0.7 mole) of phosphorus pentachloride (Notes 1, 2 and 3). This mixture is transferred (Note 4) as quickly as possible to a 500-cc. Claisen flask equipped with a 360° thermometer and an air-intake tube (Note 5). The Claisen is connected by means of a double-length air condenser to a 250-cc. filter flask which in turn is connected to a water pump (Note 6) through a manometer. 

The heating liquid is pure concentrated sulphuric acid, with which the bulb of the flask is three-quarters filled. The substance, in powder form, is introduced into a small, thin-walled capillary tube. Such tubes are made as follows from test tubes (preferably from damaged tubes which must, however, be clean and dry ). The tubes are rotated in the flame of the blow-pipe till soft and then drawn out rapidly already after short practice the student can strike the correct diameter, which should be 1 0-1 -5 mm. internally. Suitable portions of the drawn-out material are cut off with scissors. It is convenient to cut double lengths (about 12 cm.), so that by sealing each length in the middle (micro-burner) two melting-point tubes are obtained ready for use. 

Block copolymers are named by using dashes (double-length hyphens) for the bonding of bloeks with each other and with junction units. With graft and star polymers, the grafts or the arms, respectively, are eonsidered to be substituents to the main chain, and the structure is named in the same way as a regular or irregular polymer. Table 8 lists some examples. 

Socrates Now watch how he recollects things in order—the proper way to recollect. You say that the side of double length produces the double sized figure It must be equal on all sides like the first figure, only twice its size, that is, eight feet. Think a moment whether you still expect to get it from doubling the side. 

This will be needed later. We now need another equation. First, consider that when using BDF, we calculate the new vector from the two old ones, and the previous present one becomes the previous older one. This can be expressed as a vector of vectors operation. Let the new double-length vector e = [e e]T, consisting of the two known vectors, and the new one, e = e e 7, the... 

The values of CBF differ slightly since they were obtained by different techniques vertical films in a frame put into a horizontal X-ray diffractometer [341,342] and horizontal film (Fig. 2.21) in a synchrotron ray diffractometer [343], The data presented in the above table confirm the concepts established from previous investigation about the structure of both types of black films a sandwich model of two adsorption layers of amphiphile molecules with an aqueous core in between (for CBF) and bilayer of amphiphile molecules in which molecules of the solvent are incorporated (for NBF). The bilayer structure of NBF has been confirmed [344] for films from aqueous solutions of C]2E6 obtained in the measuring cell shown in Fig. 2.21. Their thickness of 6 nm found is less than the double length of the amphiphile molecule.

In order to plot the corresponding titration curves, copy (using Paste Special => Values) the column for Vb/Va) t below that for Vb/Vai and make a second, double-length column for pH to the right of the existing data in the spreadsheet to facilitate plotting the pH versus (VbIVa) and VbIVa)t. Plot the titration curves.

On the basis of these results Thomas suggests that the normal alcohols associate in double-length rod-shaped molecules by forming two bonds between the two hydroxyl groups—the cyclic dimer. It is proposed that the... 

The equilibrium state at A = 2 (Fig. 8a) corresponds to a very thin secondary film, which is stabilized by the short-range Bom repulsion. The secondary film represents a bilayer of two adjacent surfactant mono-layers its thickness is usually about 5 run (slightly greater than the doubled length of the surfactant molecule) (77). Secondary films can be observed in emulsion floes and in creamed emulsions.

Finally, MP2 can be done with all integrals in memory. A double-length integral list is required, so that twice as much memory is required as for in-core SCF. This is again very CPU-efficient but has even more stringent memory requirements than in-core SCF. 

If the number of fuel rods is increased, keeping the core pressure drop constant, the frictional pressure drop will also increase due to the smaller equivalent hydraulic diameter. To compensate for the higher frictional pressure drop, a double-length bundle (1-m long) was adopted. This avoids the sizeable pressure drop due to the endplate and bundle junctions. 

A 52-element bundle geometry was chosen due to good symmetry and compactness of the array. The reduction in the number of endplugs and endplates, due to the double-length bundle, gives a uranium credit that can be used to increase the bundle uranium mass. The pellet diameter is very similar to that of the smaller CANFLEX elements, but with a slightly greater clad thickness and gap clearance compared to the standard 37-element bundle. 

Virtually aU digital signal processor integrated circuits contain one or more double-length accumulator registers that permit the sum-of-products in Eq. (8.67) to be accumulated without quantization. In this case only a single quantization is necessary following the summation and... 

Newcastle Kiln. A type of intermittent kiln formerly popular in the Newcastle-on-Tyne area. In its original form it is a rectangular kiln with two or three fireboxes at one end and openings for the exhaustion of waste gases at the base of the other end-wall, which incorporates a chimney. In a later design the kiln is of double length, there are fireboxes at each end, and the waste gases are removed from the centre of the kiln.
