Inspection containers

It may be advisable to inspect containers midway through the incubation period. The filled units should be briefly inverted and swirled after filling to assure closure contact with the medium. Personnel who have had specific training in the visual inspection of media-filled units should perform these incubator checks. 

Inspect containers regularly for tears, splits, breaks, leaks, rust, or corrosion. When a container is damaged, pnt on appropriate personal protective equipment and take immediate action. If the damaged container is an aerosol can or fumigant tank that contains pesticides under pressure, use special care to avoid accidentally releasing the pesticide into the air. When a container is damaged ... 

The results showed 41% of the grade samples determined to be contaminated by visual inspection contained less than 20 ppb aflatoxin when analyzed by both ELISA and HPLC methods 18.7% of peanuts determined to be uncontaminated by visual inspection actually contained aflatoxin with a range of 26-2542 ppb. The results of ELISA and HPLC agreed in 98.6% of the composite sample analyses with the detection of 20 ppb or greater. However, the ELISA screening method failed to give positive tests 12 of 13 times when the aflatoxin content was between 20-43 ppb in the component samples. Samples were analyzed at the rate of one every two minutes when duplicate analyses of ten samples (20 analyses) were performed.

A report of the inspection containing the prescribed particulars (no form or official register is necessary) shall be made within 24 hours of the inspection and retained xmtil 3 months after the work has been completed. Only one report needs to be made every 7 days in respect of item (a) above for excavations and items (a) and (b) for coffer-dams and caissons. Reports of inspections following the other incidents listed above must be made before the end of the working period. 

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. 

Homogeneity of data. Homogeneous data will be uniform in structure and composition, usually possible to describe with a fixed number of parameters. Homogeneous data is encountered in simple NDT inspection, e.g. quality control in production. Inhomogeneous data will contain various combinations of indications from construction elements, defects and noise sources. An example of inhomogenous data are ultrasonic B-scan images as described in [Hopgood, 1993] or as encountered in the ultrasonic rail-inspection system described later in this paper. 

In service inspections of French nuclear Pressure Water Reactor (PWR) vessels are carried out automatically in complete immersion from the inside by means of ultrasonic focused probes working in the pulse echo mode. Concern has been expressed about the capabilities of performing non destructive evaluation of the Outer Surface Defects (OSD), i.e. defects located in the vicinity of the outer surface of the inspected components. OSD are insonified by both a "direct" field that passes through the inner surface (water/steel) of the component containing the defect and a "secondary" field reflected from the outer surface. Consequently, the Bscan images, containing the signatures of such defects, are complicated and their interpretation is a difficult task. 

An invariant pattern recognition method, based on the Hartley transform, and applied to radiographic images, containing different types of weld defects, is presented. Practical results show that this method is capable to describe weld flaws into a small feature vectors, allowing their recognition automatically by the inspection system we are realizing. 

Of course, all the data displayed on a computer can be printed as like as an inspection report (protocol) (see Fig. 1,2). The report contains inspection results in short the LMA readings divided in four levels number of LF per a lot of the rope length, e.g. per 6 dia. 

The report contains also other information which needs to be performed according to the standard [7] date, rope indification, rope diameter and construction, length of rope examined, inspection speed etc. Thus, a user gets the document obtained without very long and subjective data processing by a skilled and experienced operator. 

Introducing the Selenium for gammagraphic weld inspection at significantly improved quality levels of the radiographs we have also designed an exposure unit for Selenium. This unit is fuUy compatible with both models, M6 and Ml8. Different from the exposure units for iridium, which are Type B(U) containers, the Source Projector M-SE for Selenium is a Type A container with a maximum loading of 3 TBq (80Ci) Selenium. 

The advent of a portable source of very high energy x-rays has opened up x-ray inspection possibilities in a wide range of environments. Applications include such fields as nuclear waste containers, bridges, nuclear and fossil power plants, surface and airborne transportation systems, space launch systems and other thick section NDT and other inspection problems that cannot be solved imaged using other NDT methods.

In order to provide the necessary coupling fluid the grip of the probe holder contains a small tank with a mixture of glycerine and water. Thus the operator is able to provide some drops of the liquid to every blade to be inspected. 

The HILL-SCAN 30XX boards can be used in different PCs. Desktop- and tower-PCs as well suited for laboratory uses. For in-field inspections rugged notebooks and portable PCs are advantageous. A typical portable system is shown in Fig. 2 (USPC 3010), used in MUSE (Mobile Ultrasonic Equipment). This portable PC not only contains the boards for ultrasonic testing but also a controller with power supply for stepper motors, so that a manipulator can be connected directly. The MUSE system is enlarged with a water circulation system which enables a local immersion technique" for in-field inspections. A typical result is shown in Fig. 3, which presents a D-scan of a CFRP- component in RTM-techniques. The defect area caused by an impact is clearly indicated. The manipulator is described in [3]. 

The complete advanced 3D inspection system contains three main components the Advanced Inspection Robot - AIR-1, the new generation P-scan ultrasonic data acquisition system - PS-4 and the 3D ultrasonic simulation system - UltraSIM. 

It has developed a real time method to compare successive non-destructive inspections of the steam generator tubes in nuclear power plants. Each tube provides a safety barrier between the primary and secondary coolant circuits. Each steam generator contains several thousands of tubes whose structural integrity must be ensured through the lifetime of the plant, Therefore, Laborelec performs extensive nondestructive tests after each plant outage. 

In the excited states for the same potential, the log modulus contains higher order terms mx(x, x, etc.) with coefficients that depend on time. Each term can again be decomposed (arbitrarily) into parts analytic in the t half-planes, but from elementary inspection of the solutions in [261,262] it turns out that every term except the lowest [shown in Eq. (59)] splits up equally (i.e., the/ s are just 1 /2) and there is no contribution to the phases from these temis. Potentials other than the harmonic can be treated in essentially identical ways. 

The next simplest loop would contain at least one reaction in which three electron pairs are re-paired. Inspection of the possible combinations of two four-electron reactions and one six-electron reaction starting with CHDN reveals that they all lead to phase preseiwing i p loops that do not contain a conical intersection. It is therefore necessary to examine loops in which one leg results in a two electron-pair exchange, and the other two legs involve three elechon-pair exchanges fip loops). As will be discussed in Section VI, all reported products (except the helicopter-type elimination of H2) can be understood on the basis of four-electron loops. We therefore proceed to discuss the unique helicopter... 

In a similar way Table II summarizes how the phase changes upon interconversion among the isomers. Inspection of the two tables shows that for any loop containing three of the possible isomers (open chain and cyclobutene ones), the phase either does not change, or changes twice. Thus, there cannot be a conical intersection inside any of these loops in other words, photochemical transformations between these species only cannot occur via a conical intersection, regardless of the nature of the excited state. 

Our next task is to derive all possible K values for a given Nj. First, we refer to a few special cases It was shown before that in case of Ay = 1 the D matrix contains two (—1) terms in its diagonal in case the contoui surrounds the conical intersection and no (—1) terms when the contour does not surround the conical intersection. Thus the allowed values of K aie either 2 or 0. The value A = 1 is not allowed. A similar inspection of the case Nj = 2 reveals that K, as before, is equal either to 2 or to 0 (see Section V.B). Thus the values K = or 3 are not allowed. From here, we continue to the general case and prove the following statement ...
