Silene EF stocks contain 2.4, 3.8, and 5.0 parts of diethylene glycol, respectively. 

In addition to the 1 part of MBTS shown in recipe, the 20 vol HiSil 233 stock contains 0.25 parts TMTD and 0.5 parts triethan o1 amine the 30 vol stock contains 0.5 parts TMTD and 2 parts triethano1 amine and the 40 vol stock contains 0.5 parts TMTD and 3 parts triethano1 amine. 

The HiSd 233 stocks contain 2.3, 3.5, and 4.8 parts of diethylene glycol, respectively. The 30 vol stock contains 1.2 parts MBTS and 0.15 parts TMTD instead of the combination in the recipe the 20 and 40 vol stocks contain 1.5 parts MBTS and 0.1 parts TMTD. 

If the stock is to receive a second impregnation, it must be rebaked. In the past, stock containing raw impregnating pitch could be graphitized directly. However, the air polluting effect caused by this practice has made rebaking a necessary preliminary step to graphitization in order to achieve effective environmental control. 

In the manufacture of colored papers, it is best to add the dyestuffs before addition of rosin size and alum. This is not always possible in continuous dyeing procedures where dyestuffs must be added to stock containing size and/or alum, and this may cause premature laking of the dyestuffs and subsequent loss of tinctorial strength and/or dullness of shade. The proper selection of dyestuffs can help to reduce these disadvantages.

The reactor system in a pilot plant contains stock tanks that are 24 in in diameter and 36 in high. A relief system must be designed to protect the vessel in the event of fire exposure. The vessel contains a flammable polymer material. What rupture disc diameter is required to relieve the vessel properly Assume a discharge pressure of 10 psig. The molecular weight of the liquid is 162.2, its boiling point is 673°R, the heat of vaporization is 92.4 Btu/lb, and the heat capacity ratio of the vapor is 1.30. 

When the feed stock contains constant proportions of reactive impurities, the rate of decline also may depend on the concentration of the main reactant, thus... 

Batch cultivation of P. mendocina KRl was carried out in 2 x 2 L centre column Erlenmeyer flasks. Each flask contained stock solution 1 (8 mL) and deionized water (390 mL). This solution was autoclaved and cooled before adding 400 /iL stock solution 2,400 uL stock solution 3 and 400 pL stock solution 4. Toluene (600 /iL) was added to the centre column. Overnight starter cultures were used to inoculate (2% v/v) the growth medium. Cultures were incubated at 30 °C shaking at 200 rpm. 

The rather low concentration of the desired p-xylene component in the Parex unit feed means a large fraction of the feed stock contains other A8 components that are competing for adsorption sites in the adsorbent zeoHte cages. Due to this typically lean feed, a significant hike in the Parex unit capacity can be obtained by even a small increase in the composition of the p-xylene. Techniques to increase the p-xylene feed concentration include greater dealkylation of the ethylbenzene in the Isomar unit by converting from an ethylbenzene isomerization catalyst to... 

All catalysts will show abnormal aging if the charge stock contains even minute quantities of heavy metals such as copper, nickel, and vanadium (14). 

Buist and Davies during a study of natural rubber and chloro-prene rubber stocks containing various carbon blacks point out that certain properties are closely related. For example, for natural rubber the following groups are highly correlated. 

Deoxynbonucleoside triphosphates (dNTPs). The stock contains 6 25 mM of each dNTP- The stock contains 6.25 mM of each dNTP. 

Continuous casting of filtered molten metal into giant coils (50,000 lb 22,680 kg) of 0.250-inch ( - 6.4 mm) strip. This eliminates all hot rolling and intermediate annealing for rolling thin sheet products, such as foil, container stock, siding, etc. 

A linear relationship is often observed between vanadium removal and sulfur removal, whereas the relationship between nickel and sulfur removal is linear but of smaller slope (Massagutov et al., 1967). For asphaltene-containing stocks, this phenomenon is interpreted on the basis of heteroatom distribution within the asphaltene micelles (Beuther and Schmid, 1963). Sulfur and vanadium are concentrated on the exterior, whereas nickel is concentrated in the interior. Conversion of the asphaltene generally leads to simultaneous removal of sulfur and vanadium, whereas nickel removal is more difficult. 

Figure 4. The technique of serial transfer. An RNA sample which is capable of replication in the assay is transferred into a test-tube containing stock solution. This medium contains the four nucleoside triphosphates (ATP, UTP, GTP and CTPJand a virus specific RNA polymerase, commonly QP-replicase because of the stability of this protein, in a suitable buffer solution. RNA replication starts instantaneously. After a given period of time a small sample is transferred to the next test-tube and this procedure is repeated about one hundred times. The transfer has two consequences (i) the material consumed in the replication is replaced, and (ii) the distribution of RNA variants is subjected to a constraint selecting for the fastest replicating species. Indeed, the rate of replication is increased by several orders of magnitude in serial transfer experiments starting out from natural QB RNA and leading to variants that are exclusively suited for fast replication and hence are unable to infect their natural hosts, Escherichia coli.
