A prospective method for the utilization of diacetylene by its conversion to 2-mercapto-4-methylpyridine via the reaction of l-methoxybut-l-en-3-yne with thiourea has been brought about at an industrial level (78USSRP570580 81USSRP791713 84MI2 00ZPK619). Kinetic data for this reaction and optimal synthetic parameters for the end product have been reported (84ZPK1801).

The authors of this paper propose for the first time an updated, prospective method for impedance spectroscopy based on an essentially new design of the electrode system. In this case, the electrode system is replaced by an extended electric conductor immersed into the electrolyte. An alternating voltage is applied to the ends of the conductor connected directly to a measuring device. This signal induces two identical and electrochemically conjugated electrodes at the both ends of the conductor. The polarity of these electrodes is variable by fed frequency. They come in contact at the non-polarized centre of the extended conductor. The linear coordinate of the non-polarized centre is estimated on the condition of a conjugation of cathodic and anodic process ...

The MPF and TMGM prospecting methods are based on the use of metallo-organics (fulvates and humates of metals) and oxides of iron and manganese (metals bound in oxides and hydroxides of iron and manganese). These forms of metals are the result of the secondary fixation of the movable fomis in rocks and have features such as (1) increased concentration coefficient and (2) only a weak bond with their initial geological source (in comparison, for example, with the movable forms collected in CHIM and MDE). Samples for MPF are taken from the humus-enriched layer at a depth of 5-10 cm, and samples for TMGM are taken from the sand-clay layer at a depth of 15-20 cm. 

Various categories of candidate methods may be considered. New methods described in the scientific literature may require in-house development. Commercial kit methods, on the other hand, are ready for implementation in the laboratory, often in a closed analytical system on a dedicated instrument. When reviewing prospective methods, attention should be given to the following ... 

When Edward Drake sank the first oil well as Titusville in 1859, nothing was known of prospecting methods or drilling techniques. A modest wooden structure supported a vertical ram, with an old motor and a series of iron pipes. Modern wells require a detailed study of the bedrock and can be drilled to over 20,000 feet under the most difficult conditions.

We have examined several carrier matrices for their ability to immobilize p-glucosidase, including activated charcoal, nylon, chitosan, bentonite, kaolin, silica gel, and titanium dioxide. The results indicated that immobilization by covalent binding on silica gel and by physical adsorption on kaolin were the most prospective methods for improvement of the economic parameters of enzymatic hydrolysis of cellulose. Here, we report on these two supports.

Two geological abnormity bodies, named with 1 and 2, were recognized by three dimensional seismic prospecting method in the prospecting areas. These two abnormity bodies were judged as collapse column from their development features. 

Prospective methods Several new techniques for the detection of fruit juice adulteration are still vmder development. These include pyrolysis mass spectrometry, size-exclusion chromatography, NIR spectrometry, and an expert system for data interpretation. With the methods of falsifying juices being so numerous and diverse, however, it is vm-likely that any single method will ever be capable of detecting all forms of falsification. 

This section discusses a variety of rather theoretical methods of prospective evaluation fault tree, traffic conflict technique, operational field and effectiveness in the field, and scenario technique. Section 2.6 focuses on case-by-case prospective methods. 

The next evolution of the method presented by Busch is called PreEffect-iFGS. It is a prospective method for evaluating the field effectiveness of integral pedestrian protection systems [21]. The main procedures of Busch, i.e., selection of relevant accidents, simulation with/without system, translation into injury severity, and calculation of the effectiveness, stayed the same with some additions. The improvement is an incorporation of test results for active and passive safety systems derived from hardware testing [54]. The initial version also includes an automated backwards simulation of each accident based on the values available in GIDAS. The results are then transferred into the commercial software PC-Crash and are then simulated forward with and without the measure in question. 

Detection of H-bonds by IR-spectroscopy relies on displacement of the absorption band, e.g. of v(OH), however, this effect actually depends both on the structure of the molecule as a whole, and on the attached mass of vibrating atoms. The most prospective method of studying H-bonds is through the electronic structure of substances, where the effect of mechanical characteristics of molecules is small. One of... 

Prospective methods look at which risks may occur and assess the severity of these risks, in order to subsequently choose which actions should be taken to prevent errors and deviations. In the preparation of medicines prospective methods can be used for the initiation of new activities or purchasing a new equipment (see Sect. 21.5.2), as part of change control (see Sect. 35.6.10) and in planning of qualification and validation activities (see Sect. 34.14).
