Survey method

Both survey methods are mainly employed to define large scale structures such as basins. Based on the resulting maps, seismic surveys are then carried out.

The survey method relies heavily on interviews to gather data and typically involves little or no on-site verification or observation. Results can be obtained in a timely and cost-effective mannen however they may reflect the bias of the individual filling out a self-administered questionnaire. 

As with audits, survey results form the basis of a facility-specific report for circulation to facility management and the PSM team. This report may follow the questionnaire format, with responses tabulated and analysis and commentary provided at the end. If necessary, baseline PSM assessments can be performed by a single individual using a survey method. 

Soil resistivity The role of soil in the electrical circuitry of corrosion is now apparent. Thus the conductivity of the soil represents an important parameter. Soil resistivity has probably been more widely used than any other test procedure. Opinions of experts vary somewhat as to the actual values in terms of ohm centimetres which relate to metal-loss rates. The extended study of the US Bureau of Standards presents a mass of data with soil-resistivity values given. A weakness of the resistivity procedure is that it neither indicates variations in aeration and pH of the soil, nor microbial activity in terms of coating deterioration or corrosion under anaerobic conditions. Furthermore, as shown by Costanzo rainfall fluctuations markedly affect readings. Despite its short comings, however, this procedure represents a valuable survey method. Scott points out the value of multiple data and the statistical nature of the resistivity readings as related to corrosion rates (see also Chapter 10). 

Electrical survey methods may be used as an indication of suspected corrosive areas where surface conditions permit sufficiently accurate measurements. Such surveys are most effective in nonurban environments. Common survey methods include, but are not limited to, the following ... 

VII-3.2.3 Utilization. The use of this survey method may be limited by adverse conditions (such as excessive wind, excessive soil moisture, or surface sealing by ice or water). The survey shall be conducted at speeds slow enough to allow an adequate sample to be continuously obtained by placement of equipment intakes over the most logical venting locations, giving consideration to the location of hydrogen gas facilities and any adverse conditions that might exist. 

VII-3.4.3 Utilization. This survey method shall be limited to areas where adequate vegetation growth is firmly established. This survey shall not be conducted under the following conditions ... 

Other acceptable survey methods shall be used for locations within a vegetation survey area where vegetation is not adequate to indicate the presence of leakage.

Level 1 sampling provides a single set of samples acquired to represent the average composition of each stream. This sample set is separated, either in the field or in the laboratory, into solid, liquid, and gas-phase components. Each fraction is evaluated with survey techniques which define its basic physical, chemical, and biological characteristics. The survey methods selected are compatible with a very broad spectrum of materials and have sufficient sensitivity to ensure a high probability of detecting environmental problems. Analytical techniques and instrumentation have been kept as simple as possible in order to provide an effective level of information at minimum cost. Each individual piece of data developed adds a relevant point to the overall evaluation. Conversely, since the information from a given analysis is limited, all the tests must be performed to provide a valid assessment of the sample.

Geotechnical surveys aim is to optimise the binary system management. To a great extent a correct decision of the task would depend on the rational selection of the survey method and the optimal identification of the scope of the survey, and also on the design, construction, and operation at different stages. 

The traditional geotechnical survey is characterized by discrete information. It means that old survey methods cannot provide comprehensive data on the geological structure, substance composition and properties of the whole pipeline route. This principle is not observed in all the three main gas pipeline cases. The technical documentation of the Baku-Tbilisi-Ceyhan pipeline, the South-Caucasus Pipeline system, and particularly of the North-South Caucasus Gas Pipeline does not include longitudinal geotechnical profiles of the route and the pipeline corridor in the geotechnical maps. Trial pits and boreholes that are arranged approximately 1,5-...

TLC is the more popular of the two planar techniques. It is used for fast screening of mixtures and for surveying methods for use in columns. Quantitative analysis is better accomplished by column LC, but quantitative TLC is increasing in popularity as the instrumentation improves. Table 4 contains a summary of the advantages and disadvantages of the planar methods. 

The types of biological methods that need to be carefully evaluated and, if appropriate, standardized for field use include (1) laboratory screening tests to assess the relative hazard of chemical mixtures, (2) field survey methods to detect changes in biological populations, and (3) monitoring techniques to detect... 

Surveys of Environmental Impacts. Field survey methods focus on assessing changes in the condition of entire populations and ecological community functions (e.g., pest species proliferation, species diversity, litter decomposition rate, changes in the rate of primary production). These methods under certain circumstances may relate effects to specific pollutant sources, but most frequently they are used to indicate that a problem does exist. A current application of survey methods being developed emphasizes identification of indigenous species to serve as surrogates for a portion of the ecosystem. 

The method surveyed seems to be advantageous and to some extent complementary to the important methods in which the commercially available CD silica stationary phases are used. Moreover it involves sometimes additional factors which could improve separation such as adsorption on an RP phase or second stage complexation. The surveyed method has not been totally explored both in theory and/or in practice. The newest results achieved via methylated CD s confirm this opinion(38,39). Therefore still it is to early to draw general conclusions. ... 

Concern assessment experts of social sciences including economics identify and analyze the issues that individuals or society as a whole link to a certain risk. For this purpose the repertoire of the social sciences such as survey methods, focus groups, econometric analysis, macro-economic modelling, or structured hearings with stakeholders may be used. 

The survey method, which utilizes the weedy host to screen pathogens, has been utilized to discover most of the host-specific bioherbicide candidates currently under development. Again, the disease triangle, i.e., the host, bioherbicide pathogen, and the environment determine bioherbicide efficacy. Often, disease symptoms may not occur in epidemic proportions. As such, manifestation of disease symptoms may occur in a very narrow time span when all factors of the disease triangle interact. Thus, discovery of host-specific, foliar, epiphytic bioherbicide candidates is dependent on...
