Early types

Alloy Compositions and Product Forms. SteUite 21, an early type of cobalt-base high temperature alloy, is used primarily for wear resistance. The use of tungsten rather than molybdenum, moderate nickel contents, lower carbon contents, and rare-earth additions typify cobalt-base high temperature alloys of the 1990s as can be seen from Table 5.

Crisp, Lewis Wilson (1976a) found that for two early types of glass-ionomer cement (ASPAII and ASPAIV) compressive strength continued to increase for at least a year. Recently, Williams Billington (1989) have found that this behaviour does not hold for all modem commercial... 

The CoIII-alkyl bond was established some time ago with the characterization of simple complexes with Co—CH3 or other Co—R groups. Incorporation of R as an axial ligand in Co111 porphyrins, Schiff base and bis(dimethylgloximato) compounds were early types defined, and examples continue to appear. This is a key feature of cobalamin (B12) model complexes and a review of this area appears in Section 6.1.3.1.1. The deceptively simple isoelectronic alkyl homologs of [Co(NH3)6]3+ and [Co(en)3]3+, (122)531 and (123), have appeared since the first edition of... 

Soda (composed of sodium oxide) and potash (composed of potassium oxide) are relatively easy to obtain or to make, work, and handle. Although they do not occur naturally, they could be quite easily prepared in the past by burning some plants (see Textbox 28). Both these oxides were used as fluxes for making early types of glass articles, particularly small vessels and decorative objects. 

Polymeric cationic retarders that contain up to several hundred cationic groups per molecule have been proposed [45-47]. The early types [45,46] were described as quaternised polyamines (section 9.5) of relative molecular mass 1000-20 000, as compared with 300-500 for conventional quaternary ammonium compounds. Polyacrylamides of molecular mass 2500-780 000 have been evaluated more recently [47].

LINERs are weaker emission-line regions in certain elliptical and early-type spiral galaxies (e.g. M51 and M81) showing relatively strong lines of [O I], [N ii] and [S n], similar to SNR. It is not clear whether they are excited by shocks like SNR or by a very dilute (i.e. low u) non-thermal spectrum. 

Typical timescales 1/v range from as little as 108 years (roughly the dynamical timescale) for a starburst galaxy to maybe 2 x 109 years in an early-type spiral to... 

In the beginning, a portable olfactometer operated only by one person was required to measure odour direct at the odour emitting sources in and around livestock houses. The early type TO 4 fulfilled both requirements. 

The specific rates of solvolysis of benzyl p-toluenesulfonate and nine benzylic-ring-substituted derivatives (324) have been satisfactorily correlated using Aij and Tots scales within the extended Grunwald-Winstein equation. The reactions of Z-phenylethyl X-benzenesulfonates (325) with Y-pyridines (326) in acetonitrile at 60 °C have been studied at high pressures. The results indicated that the mechanism of the reaction moves from a dissociative 5)vr2 to an early-type concerted 5)vr2 with increasing pressure. 

Figure 10.67 shows a mole% phase vs temperature plot for a Ti-48Al-2Mn-2Nb alloy of nominal composition variations of this alloy with A1 in the range 45-48at% are commonly used. It is a straightforward a / y alloy which can be heat treated in the a condition before transforming on cooling to (02 + 7) and very much exhibits the prototype microstructure for the early type of alloys. 

More substantial increases in the rate of strength development are obtained by the use of superplasticizers. As mentioned previously, because of the dramatic water reduction that can be achieved by the use of higher dosage of the superplasticizers, significant cement reduction or a change in the type of cement (from a high early Type 111 to a normal Type 1) is possible (Tables 7.28, 7.29 and 7.7). 

In the early type of flintlock, known as snaphance, the mechanism was constructed so that when the trigger was pulled, the flint struck against a sloping piece of iron, known as the "frizzen" causing a shower of sparks to strike the "pulverin" in the priming pan. 

Historically speaking, early types of ammunition were identified solely by size and shape. 

In early type stars, the bottom boundary penetrates into convective core (Osaki 1975). Accordingly, convective motion of eddies excites sound waves, as in the case of acoustic noise emmision from incompressible turbulence, shown by Lighthill (1978). Since the frequency of excited waves is higher than the Brunt-Vaisala frequency at the photosphere, the waves are not trapped, but running outward (cf. Unno et al 1979). 

Now, strong stellar wind blows on the photosphere of early type stars (cf. de Jager 1980), so that mass outward flow vHin(i up to 1 cm/sec exists in the edge of core. The precise consideration is required to determine whether the convective velocity of C is more effective for dredge-up than vwind or not. Quantative results will be shown in the seperate paper.

Thus, by assigning 0(a = 1 to the early-type main-sequence primaries in semi-detached systems, similar practical analysis as done in the previous work of Kitamura and Nakamura (1986) has been carried out to determine empirical values of the exponent for the secondaries of those systems which fill the critical Roche lobe. 

Methanolysis of die sulfonates (175)141 and the reaction of the sulfonate ester (102) with hydroxylamine (103)88 were looked at earlier. Yoh and co-workers have looked at die reactions of (Z)-phenylediyl (X)-benzenesulfonates with (Y)-pyridines in acetonidile under pressure and die structure-reactivity relationships established show that as die pressure is increased die mechanism moves from a dissociative 5n2 to early-type concerted 5k2.276 In otiier sdtdies also under pressure the same group found that a mechanistic change from associative, k 2 to late-type 5n2 occurs as the pressure is increased in die reaction of (Z)-phenacyl (X)-benzenesvdfonates with (Y)-pyridines in acetone.277...
