Content requirements

Improving the cetane number as well as lowering the aromatics content requires higher partial pressures as well as higher hydrogen consumption. 

Polyvinylpyrrohdinone/vinyl acetate copolymer (PVP/VA) was developed as an improved, less hygroscopic version of PVP. The monomer ratios control the stiffness and the resistance to humidity however, too high a vinyl acetate monomer content requires another solvent in addition to water to completely solubilize it. 

Many commercial gases are generated by burning hydrocarbons (qv) eg, natural gas or propanes, in air (see Gas, natural Liquified petroleum gas). The combustion process, especially the amount of air used, determines the gas composition. For a given fuel-to-air ratio, the gas composition can be used to determine the water vapor content required to achieve a desired equiUbrium carbon content of the austenite (see Combustiontechnology).

Concentration. Evaporation procedures depend on the concentration of the solution produced during neutralization and the water content required for the subsequent production of soHd product. Neutralizer solutions can contain as Httle as 2% and as much as 25% water feeds to drum granulators can contain 5% water, prill towers 0.3 to 0.5% water. 

These relationships predict the binding Hquid content for wet agglomeration with an accuracy of only ca 30%. The Hquid content required to agglomerate a particular feed material depends, for example, on the interfacial properties of the system (45). Typical values of moisture content required for hailing a variety of materials are listed in Table 2. Very accurate information on the optimum Hquid content to agglomerate a particular feed material must be obtained from experimental tests. 

You may only need one procedure that covers all the requirements but this is not always practical. The provisions you make for specific quality records should be included in the procedures for controlling the activity being recorded. For example, provisions for inspection records should be included in the inspection procedures, provisions for design review records should be included in the design review procedure. Within such procedures you should provide the forms (or content requirements for the records), the identification, collection/submission provisions, the indexing and filing provisions. It may be more practical to cover the storage, disposal, and retention provisions in separate procedures because they may not be type-dependent. Where each department retains its own records, these provisions may vary and therefore warrant separate procedures. 

The scarcity of data and their invaluable content require that they be recorded in the most careful manner. The human eye is an incredibly powerful and versatile instrument, with an amazing dynamic range. But almost the entire universe is beyond its reach. Modem telescopes have a sensitivity 9 to 10 order of magnitude higher, yet they are barely able to provide a glimpse at the youngest galaxies, least to say stars. 

Accurate interpretation of the formation properties (porosity, permeability and irreducible water saturation) requires reliable estimates of NMR fluid properties or the relationship between diffusivity and relaxation time. Estimation of oil viscosity and solution-gas content require their correlation with NMR measurable fluid properties. These include the hydrogen index, bulk fluid relaxation time and bulk fluid diffusivity [8]. 

The homogeneity of the product should be addressed. The adequacy of mixing processes should be shown (and confirmed with appropriate process validation data) and potential segregation discussed (as affected by surface properties, crystallinity, particle size, etc.). The Ph Eur uniformity of content requirements should apply to the dosage forms and uniformity of distribution needs to be shown between batches and within batches. The need for appropriate routine tests as part of the release specification should be discussed. 

Figure 3A shows the kinetics of poly(3HB) accumulation for several specific formation rates, depending on the duration of accumulation. As can be seen, the poly(3HB) content approaches a value of 100% asymptotically. However - and this might be considered trivial - how closely the upper limit is reached is ruled by the fact that an increasing content requires increasing synthesis while the capacity is decreasing (Fig. 3B). Economically acceptable contents are reached after very different periods of accumulation this means that the specific formation rate is a very important parameter which depends on the organism involved and, with a given genotype, on the substrate used. Hence we should fo-...

This book covers the key content of all the specifications of the four awarding bodies AQA, Edexcel, OCR and WJEC. The content requirements differ between the specifications.

There is a critical organic content required for incineration without the need for additional fuel, and Figure 10.5 shows the relationship between organic content and combustibility. 

The transformation of straw and agrofood residues with high sulfur and ash content requires the development of materials for sulfur abatement at high temperature, tar cracking and as monolith for syngas production by exothermic or autothermal processes thanks to catalysts supported on materials with a high thermal conductivity.

This is one of the recommended drying methods for moisture in animal feed (Padmore, 1990, p. 69). About 2 g animal feed is dried to constant weight at 95-100°C under a pressure of 100 mmHg for about 5 h. A high molasses content requires s50 mmHg at 70°C. Vacuum ovens are ideal for drying... 

The same apparatus was used, but quantities of paste were removed to give an air space in the vessel. On rapid agitation the volume increased, dependent on the air content required. Paste viscosities were measured, using a Stormer viscometer, which is a type of concentric cylinder viscometer. Although it is possible to obtain results in absolute terms, for comparative purposes the times for 100 revolutions of the rotor under a fixed applied torque were recorded. 

The expansion achieved in concrete containing these admixtures is dependent on the type of aggregates used in the mixture. Thus the desired level of shrinkage compensation should take into account the modulus of the aggregate to be used on the job. The effect of cement and water contents on the extent of expansion should also be considered. Minimum cement content required to achieve desired expansion should be determined through mix trials. Compatibility with other admixtures may also need trials and the manufacturer s recommendation should be followed [80]. 

The water content, required to produce a given slump, can be significantly reduced when a latex admixture is used and the extent of the reduction increases with an increase in the polymer-cement ratio. This effect is due to... 

Waste streams with a high chlorine content require dilution before processing to limit corrosion of the vessel. Due to the 10% by weight solids limitation, there is an inherent large dilution ratio required for solid materials. No SGPV facilities are recommended in salt domes or in areas where the vessel will cross a seismic fault line. 

The aqueous solubility of solid ingredients is inversely proportional to the water content required to obtain acceptable pellets (39), as shown in...
