Investigational application

The screening of agricultural applications is summarized in Table VI-6. The most investigated applications are related to fungicides (305. 483. 

Ion-selective electrodes are a relatively cheap approach to analysis of many ions in solution. The emf of the selective electrode is measured relative to a reference electrode. The electrode potential varies with the logarithm of the activity of the ion. The electrodes are calibrated using standards of the ion under investigation. Application is limited to those ions not subject to the same interference as ion chromatography (the preferred technique), e.g. fluoride, hydrogen chloride (see Table 10.3). 

One of the extensively investigated applications of enamines to heterocyclic syntheses is based on the bifunctional character of enamine acylation products. Thus the vinylogous ureas and thiorueas obtained from enamines and phenylisocyanate and phenylisothiocyanate (-433) have been converted to aminopyrazoles and thiouracils with hydrazine (566) and phenylisocyanate (567). 

As early as 1990, Chauvin and his co-workers from IFP published their first results on the biphasic, Ni-catalyzed dimerization of propene in ionic liquids of the [BMIM]Cl/AlCl3/AlEtCl2 type [4]. In the following years the nickel-catalyzed oligomerization of short-chain alkenes in chloroaluminate melts became one of the most intensively investigated applications of transition metal catalysts in ionic liquids to date. 

Whilst nothing can improve upon the disadvantage of low molar absorption coefficients, instrumental designs and improvements with ratio recording and FT-IR instruments have virtually overcome the accuracy and instrumental limitations referred to in (b) and (c) above. As a result, quantitative infrared procedures are now much more widely used and are frequently applied in quality control and materials investigations. Applications fall into several distinct groups ... 

Another noted and prolific Japanese author in the field of functional dyes, Masaru Matsuoka of the Laboratory of Materials Science, Kyoto Women s University, has written the second chapter, dealing with leuco-quinone dyes. These are the traditional redox leuco systems employed for so many years in the vat dyeing industry, and this chapter is an invaluable review of the chemistry of these systems, drawing on recent mechanistic and structural investigations. Applications considered include not only textile dyeing, but also other more specialized areas, such as hair dyeing, color formers, and photoimaging materials. 

If you are investigating applications development, I advise you to explore Java or C as a possible programming language. Both Java and C are strong object-oriented applications development languages with a rich set of classes and methods to help you... 

Scott and coworkers [60] have also investigated applications of AM to cycloalkanes. They found, for example, that cyclooctane undergoes metathesis by 7 in tandem with 1, 4a, or 6, to give a range of cyclic products, including (surprisingly) cycloheptane, but mostly low cyclooligomers in which the carbon number is a multiple of 8. The proposed mechanism is shown in Scheme 3. 

Causal Trees were developed in an effort to use the principles of deductive logic found in Fault Tree but make it more user-friendly. Originally, private companies developed the Causal Tree Method (CTM) for safety, process safety, and environmental incident investigations applications. Rhone-Poulenc, for example, was an early user.<20.21) Multiple-Cause Systems Oriented Incident Investigation (MCSOfl) is another name for the CTM. At this time, most companies use simplified versions of fault trees for complex incident investigations. 

Among several investigated applications, an interesting one is the development of devices for the microgeneration of power based on a combustion process [35]. 

Turkey reports investigating applications of Boron compounds. To this end, Turkey is establishing the Boron Institute, which will investigate new application areas for boron and its compounds. 

The Permeable Cell Assay was optimized for E. coli K-12 (BW25113) (4). To investigate applications of this assay, P. fluorcscms, P. putida, C. ammoniagmcs, and C. glutumicum were tested. All bacteria were grown in LBG medium at 30°C for 24 h. The final OD of each bacterium was adjusted to 0.1, and the intensity of luminescence was measured. The intensity of luminescence from all bacteria tested with various concentrations of Triton X-100 showed saturated luminescence with 0.4% Triton X-100 (4). Both species of Corynehacterium... 

On the other hand, a pervaporation membrane can be coupled with a conventional distillation column, resulting in a hybrid membrane/distillation process (228,229). Some of the investigated applications of such hybrid pervaporation membrane/distillation systems are shown in Table 9. In hybrid pervaporation/ distillation systems, the membrane units can be installed on the overhead vapor of the distillation column, as shown in Figure 13a for the case of propylene/ propane splitting (234), or they can be installed on the feed to the distillation column,... 

The concept of the PCSA method is general and this method should be applicable to many types of multivariate calibration techniques. As near-infrared and other spectroscopic methods are developed further for noninvasive in vivo clinical measurements, it is critical to understand the chemical basis of measurement selectivity. Unfortunately, calibration models generated from multivariate statistics are typically accepted without further investigation. Application of the PCSA method can help to establish the chemical or spectroscopic basis of predicted concentrations. 

The following instructions address only the administrative aspects of preparing and submitting an IND and are intended primarily to provide assistance to individual Sponsor-Investigator applicants, not pharmaceutical companies. 

In the following sections, the different types of reactive filters, together with their typical applications, will be presented. The separation and catalytic combustion of diesel soot is the most important and furthest investigated application. Consequently, this type of reactive filtration, with its practical and theoretical aspects, will form the main focus of this chapter. 

For commercial processes, formed supports are more useful. Compared with other supports, fumed oxide supports showed new catalytic effects [41]. Some intensively investigated applications for these supports are abstracted in the following. SiC>2 pellets have been successfully introduced in a new generation of precious metal supports in vinylacetate monomer production [42]. This resulted in better selcctivities and an up to 50% higher space-time yield compared with supports based on natural alumo-silicates. In alkene hydration fumed silica pellets serve as a support for phosphoric acid. In this case, an increased catalyst lifetime and a higher space-time yield were observed [43]. Pyrogenic TiC>2 powder can be used as a starting material for the manufacture of monolithic catalysts [44] for the selective reduction of NOv with ammonia. 

The use of this protocol in polymer synthesis [46,73,74,213,291-304] is one of the recent topics (Scheme 83) [305]. The most extensively investigated application is toward functional materials (Scheme 84) [306].

An important and extensively investigated application of CpCo complex chemistry is the catalyzed synthesis of pyridines from alkynes and nitriles. Dissociation of the L ligands liberates the CpCo fragment to react with alkyne to form a cobaltacyclopentadiene complex. The nitrile coordinates to this intermediate and subsequently undergoes insertion to form a seven-membered cobaltacycle. Reductive coupling gives pyridine and reforms CpCo. Asymmetric alkynes add to the carbon with the bulkier substituent adjacent to the nitrile carbon. 

Cycloaddition reactions of 18-electron transition metal ti -allyl complexes with unsaturated electrophiles to form five-membered rings have been extensively investigated. These transformations constituted a family of metal-assisted cycloaddition reactions in which the metal functions as an electron-donor center. These are typically two-step processes that involve the initial formation of a dipolar metal r) -alkene intermediate (2) and subsequent internal cyclization (equation 2). The most extensively investigated application of this methodology has been with dicarbonyl-ii -cyclopentadienyliron (Fp) complexes from the laboratory of Rosenblum. These (ri -allyl)Fp complexes are available either by metallation of allyl halides or tosylates with a Fp anion, or by deprotonation of (alkene)Fp cations. ... 

The discovery of technetium (Z = 43) in 1937 and of promethium (Z = 61) in 1947 filled the two gaps in the Periodic Table of the elements. These gaps had been the reason for many investigations. Application of Mattauch s rule (section 2.3) leads to the conclusion that stable isotopes of element 43 cannot exist. Neighbouring stable isotopes could only be expected for mass numbers A 93, A < 91, A = 103 and A > 105. However, these nuclides are relatively far away from the line of jd stability. The report by Noddak and Tacke concerning the discovery of the elements rhenium and masurium (1925) was only correct with respect to Re (Z = 75). The concentration of element 43 (Tc) in nature due to spontaneous or neutron-induced fission of uranium is several orders of magnitude too low to be detectable by emission of characteristic X rays of element 43, as had been claimed in the report.

Photochemical separation, with the new capabilities of lasers as light sources, provides many new areas of investigation. Application of photochemical techniques to actinide separations alone has an enormous potential. As lasers become more reliable and economical, photochemical separation should become an attractive technique for many systems. 

Comparison of the acidic volatile profiles indicates that the EMB is similar to Romano cheese. This correlates well with the flavorists impressions of the aroma and flavor-by-mouth of this sample. Nonacidic volatile flavor profiles of EMB and Romano cheese are dissimilar. This indicates different formation pathways for these two samples. Current studies are investigating applications of the EMB as a flavoring agent and the feasibility for commercial application.
