Consequence techniques

Applications Chromatography is a preferred technique for additive analysis as it allows both separation of additives in a mixture and subsequent quantitation. Despite the developments in GC, this technique cannot separate many polymer additives. Even with its lower efficiency in comparison to GC, HPLC is today one of the cornerstones in a polymer additive laboratory. Judging by the number of publications in recent years, HPLC is first among analytical methods for additives (confirmation/identification/quantification). Most additives may be analysed by HPLC if they can be dissolved in an HPLC solvent and absorb UV light. Typical polymer/additive analyses are carried out using LPE followed by HPLC with UV or RI detection [605-611]. Verification of the identity of an analyte is then based on a combination of retention time, UV and RI evidence. RPLC is used most frequently for polymer/additive analysis, but normal-phase and SEC are also used. Consequently, techniques for additive analysis by HPLC are legion. 

Only about 6% of the total XIV content of the fruit is present in the juice vesicles. Any step in juice preparation that increases incorporation of the other tissues into the juice or that increases the extraction of XIV from those tissues will increase the limonin content of the juice. Consequently, techniques that increase juice yield, such as hard versus soft extraction, tend to increase limonin content (34). 

With fast reactions it is very important to ensure that there is rapid mixing, fast initiation and fast analysis. Special timing devices are needed. Consequently techniques special to fast reactions had to be developed. 

Non-stereoselective reactions produce either a mixture of diastereoisomers or a racemic modification. Diastereoisomers exhibit different physical properties. Consequently, techniques utilizing these differences may be used to separate the isomers. The most common methods of separation are fractional crystallization and chromatography. 

This reaction has been carried out on an industrial scale in spite of the fact that the decomposition stage is potentially hazardous. Consequently, techniques have been developed that avoid isolating a solid diazonium salt [2] (Figure 9.12). 

The two most widely used methods for molding thermoset are compression and transfer molding. Thermosets, you will recall, undergo a permanent set, i.e., become essentially insoluble and infusible under the action of heat. Consequently, techniques for fabricating thermosets must take due cognizance of and make allowance for the fact that sprues, runners, and gates are not reusable and therefore constitute rejects. 

Corrosion has its beneficial consequences. Techniques such as bluing and gilding were used to protect steel objects as heat treatment resulted in protective oxide films (43). 

Regiocontrol for the Robinson annotation is an important factor that can infiuence a synthetic route because there are two a-carbons to the keto group to be considered. Consequently, techniques for regiocontrol have been developed. Under either the basic or acidic standard annulation conditions deprotonation occurs under thermodynamic control at the higher substituted carbon and hence forms an angular substitution at the fused side of the end-product. An exception to this is steric hindrance where alkylation occurs at the least substituted a-carbon, as shown in the synthesis of 9. ... 

Particularly in Food Microbiology, the results of the assessment of a particular property of a food depend greatly on the method used for its determination. Therefore Reference Values carry little weight unless the method for assessing compliance is exactly specified. Hence methodology forms an essential part of Reference Values. Consequently techniques with enormous variability and high margin of error should be abandoned. 

Consequence techniques (looking forward to see what an event or situation might develop into). 

The measurement techniques most frequently used are derived from Raoult s and Van t Hoff s laws applied to cryometry, ebulliometry, osmometry, etc. They are not very accurate with errors on the order of ten per cent. Consequently, the molecular weight is often replaced by correlated properties. The mean average temperature or viscosity can thus replace molecular weight in methods derived from ndM. 

Injection of produced water is not a new idea, but the technique has met resistance due to concerns about reservoir impairment (solids or oil in the water may block the reservoir pores and reducing permeability). However, as a field produces at increasingly high water cuts, the potential savings through reduced treatment costs compared with the consequences of impairment become more attractive. 

By employing this technique, the frequency range best suited for a particular material can be automatically estimated and utilized for inspection, without the need to employ a tailor-made transducer. Consequently, a single wide-band transducer can be used to get near-optimal inspection results for a wide range of materials. 

This criterion resumes all the a priori knowledge that we are able to convey concerning the physical aspect of the flawed region. Unfortunately, neither the weak membrane model (U2 (f)) nor the Beta law Ui (f)) energies are convex functions. Consequently, we need to implement a global optimization technique to reach the solution. Simulated annealing (SA) cannot be used here because it leads to a prohibitive cost for calculations [9]. We have adopted a continuation method like the GNC [2]. 

It is particularly in the serial inspection of castings, that radioscopy constitutes state-of-the-art when applied in conjunction with systems for image intensification, digital image processing and automatic image evaluation. For the examination of welds, however, standardization is still non-existent, thus rendering more difficult the application of this inspection technique.As a consequence the approval procedures of the respective supervisory or certification boards are often complicated and of necessity set up for each individual case. 

We showed that experimentally recorded DACs and synthetically generated DGS curves are equivalent if the described requirements are fulfilled. Consequently an echo amplitude evaluation program has been developed which combines both techniques in one instrument. The software of the new state-of-the-art Ultrasonic Notebook USLT 2000 allows, apart from many other new possibilities, the combined or exclusive use of the reference block and the DGS method for amplitude evaluation. Even in those situations where DACs cannot be re-...
