Fig. 6. (a) Samples of the mid-sections of long bones are best suited for fluorine profiling, as this skeletal position provides the most uniform conditions. All scans were performed in the direction from the periosteal surface towards the marrow cavity. Two-dimensional maps were collected in some samples, (b) Fluorine was analysed by PIGE (proton-induced y-emission), while the distributions of Ca, Fe, Mn and Zn were detected by PIXE (proton-induced X-ray emission). C and N were analysed by NRA and emitted protons were detected in both cases, (c) Examples of developed and non-developed fluorine profiles in archaeological bone samples. The profile of an artificially fluorine enriched fresh bone sample is shown for comparison. 

Notably, the possibUity of global cell cycle arrest in non-developing T. spiralis muscle larvae poses a question of the relation of this unusual ceU cycle regulation to changes induced by the larvae in muscle cells. Those changes, involving ceU cycle... 

The non-hydrocarbon components of crude oil may be small in volume percent, typically less than 1 %, but their influence on the product quality and the processing requirements can be considerable. It is therefore important to identify the presence of these components as early as possible, and certainly before the field development planning stage, to enable the appropriate choice of processing facilities and materials of construction to be made. 

The objective of appraisal activity is not necessarily to prove more hydrocarbons. For example, appraisal activity which determines that a discovery is non-commercial should be considered as worthwhile, since it saves a financial loss which would have been incurred if development had taken place without appraisal. 

A new, non destructive method has been developed for testing high strength bolts which is based on measuring the magnetic stress on the head of a bolt. The forces originating in the body of the bolt can be determined in this way since these forces are proportional to the stress state in the head of the bolt. 

The publication of interstate Standard GOST 30415-96" Steel. Non-destructive inspection of mechanical properties and microstructure of metal products by magnetic method" - is the long-expected event for works laboratories and development engineers of non-destructive test means. 

The basic condition of the Standard application - the availability of stable coupled probabilistic or the multiple probabilistic relations between then controlled quality indexes and magnetic characteristics of steel. All the probabilistic estimates, used in the Standard, are applied at confidence level not less than 0,95. General requirements to the means of control and procedure of its performance are also stipulated. Engineers of standard development endeavoured take into consideration the existed practice of technical control performance and test at the enterprises that is why the preparation of object control for the performance of nondestructive test can be done during the process of ordinary acceptance test. It is suggested that every enterprise is operated in correspondence with direct and non-destructive tests, obtained exactly at it, for detailed process chart and definite product type, however the tests have long since been performed after development of the Standard displayed that process gives way to unification. 

The Supplement B (reference) contains a description of the process to render an automatic construction of mathematical models with the application of electronic computer. The research work of the Institute of the applied mathematics of The Academy of Sciences ( Ukraine) was assumed as a basis for the Supplement. The prepared mathematical model provides the possibility to spare strength and to save money, usually spent for the development of the mathematical models of each separate enterprise. The model provides the possibility to execute the works standard forms and records for the non-destructive inspection in complete correspondence with the requirements of the Standard. 

The AEBBL SW ains on the PC. The software uses a menu structure, easy to use by a non expert operator. AEBIL has been designed to operate in DOS environjnent in order to enhance its real-time operation capabilities. The user-interface has been developed so as to permit a window-driven operation. 

For homogeneous NDT data and repeatable inspection conditions successful automated interpretation systems can relatively easily be developed. They usually use standard techniques from statistical classification or artificial intelligence. Design of successful automated interpretation systems for heterogeneous data coming form non-repeatable, small volume inspections with little a-priori information about the pieces or constructions to be inspected is far more difficult. This paper presents an approach which can be used to develop such systems. 

Within the framework of the ANDES (Automatic Non-Destructive Evaluation System) at TNO Institute of Applied Physics two prototype applications have been developed for automated NDT data interpretation - both using the CBR methodology. 

The application of eddy currents in non destructive testing was very developed during the recent years. Adding to the defects characterization, actual studies deal with the metallurgical evaluation of materials. Surface processing allow to increase the material endurance and consequently its life duration.

The equation system of eq.(6) can be used to find the input signal (for example a crack) corresponding to a measured output and a known impulse response of a system as well. This way gives a possibility to solve different inverse problems of the non-destructive eddy-current testing. Further developments will be shown the solving of eq.(6) by special numerical operations, like Gauss-Seidel-Method [4]. 

The laminography method was developed initially for medical applications as a non-computer layer-by-layer visualization of the human body [1,2]. In this case an inclined initial X-ray beam projects an image of a specific layer of the object to the detector surface with defocusing of the other layers during a synchronous rotation of the object and the detector (Fig. 1). 

Non-polar penetrants can be effectively used in product families containing both a dry and suspension developers. 

Non-Desfructive testing can be apph ed widely in all industrial organisations during construction and after construction to determine, in first case, whether flaws have been introduced due to manufacturing process or in the second case, whether flaws have developed dtie to service conditions. NDT is therefore used to inspect...

The second approach - creation of systems for non-destructive testing quality assurance in compliance with ISO standards 9000 series - considers the quality system as an assembly of organisational strueture, procedures, processes and resources necessary for overall quality management at the laboratory. This approach requires methodieal development.
