Plating procedure

The production plan referred to previously is a work instruction, as it instructs those to whom it applies to carry out certain tasks. Control procedures may include assembly procedures, plating procedures, painting procedures, maintenance procedures, etc. and differ from process specifications (see later) in that the process specification defines the results to be achieved in operating a process rather than how to run the process. In addition to the list of contents provided in ISO/TS 16949 clause 4.9.2, the documentation should define ... 

Accordingly, we find it difficult to determine the distribution of the transverse shearing stress in a beam, much less in a plate. Procedures for determining the approximate transverse shear stress distribution in plates are described in Section 6.5.2. 

With the organism grown in this manner the sensitivity of the assay is improved. Greely et al2 2 have applied the automated respirometric method to the determination of neomycin in pharmaceutical products and compared these assays with the results obtained by the cylinder-plate procedure on the same samples. Good correlation between the two procedures was demonstrated. 

The electroless plating procedure described above was used to plate the Au nanotubules into the pores of commercially available polycarbonate track-etch filters [Osmonics, 6 pm thick, pore dia. = 50 nm (28 nm-dia. Au tubules) or 30 nm (all other Au tubules), 6 X 10 pores cm ]. The... 

The Cylinder-Plate Procedure. In this procedure the substance being assayed diffuses from cylinders placed upon a uniform thickness of seeded agar, filled or charged with a fixed volume of the analyte, or reference standards or a series of standard solutions. The petri dishes are incubated at a predetermined temperature and the zones of inhibition measured to the nearest 0.1 mm. 

The Pad-Plate Procedure. The pad-plate approach utilizes filter paper discs saturated with solution of the analyte as the reservoir. In all other respects, the system is identical to the other diffusion systems. 

Utilizing the diffusion assay systems, primarily the cylinder-plate procedure, the following limits of detection and measurement are realistic. 

Proper paint and vacuum metalizing systems, metal plating procedures, welding, and adhesives are some of the other important considerations in the fabricating process that must be factored into a program before a new plastic can be fully accepted. 

In view of the importance of the structure and composition of the active layer, several investigations have focussed on the optimization of the plating procedure and on the analysis of the coating. Mechanisms have also been proposed showing that metallic alloys are formed through steps involving intermediate oxides of Mo [142, 525-527]. 

No concerted studies on the breakdown products of ionic liquids have been carried out. It is unlikely that these will interfere with the metal species formed, but tests need to be carried out at typical current densities that would be used for commercial plating procedures. 

The hot plate procedure possesses an advantage over other methods of thermal stimulation, for example the tail flick procedure (d Amour and Smith 1941), in that it can be applied repeatedly in the same animals over a short period of time (2-3 hours) without causing tissue injury, particularly if the maximum observation duration is 30 seconds. This could be particularly useful for estimating time-course effects. The hot plate procedure also constitutes a more global estimate of nociceptive reactivity because it represents a complex willed behavior rather than a simple reflex like the tail flick. 

These data are given as zone diameters in millimeters, determined by disc-plate procedure with 6 mm discs [295]. These and other data [53] are personal communications of Dr Douglas O. Spry, Lilly Research Laboratories, Eli Lilly and Co., to whom the authors are greatly indebted. ... 

In order to build a radiation detector capable of extreme sensitivity, historical copper electroforming has produced copper of < 9 microBq/kg Th, and < 26 microBq/kg U. However, future systems require levels below 1 microBq/kg. To achieve this, a new copper plating procedure has been devised and will be modified as needed to achieve the goal using ideas presented above. However, a copper assay capability below this level is desired. Limiting features of ion exchange plus ICP/MS approaches have been discussed. A new approach is being developed to produce samples of the copper to be assayed which... 

These are really modifications of the earlier cup or ditch-plate procedures where filter-paper discs impregnated with the antimicrobial replace the antimicrobial-filled cups or wells. For disc tests, standard suspensions (e.g. 0.5 McFarland standard) of log phase growth cells are prepared and inoculated onto the surface of appropriate agar plates to form a lawn. Commercially available filter-paper discs containing known concentrations of antimicrobial agent (it is possible to prepare your own discs for use with novel drugs) are then placed on... 

In all cases the plating procedure gave highly reproducible results, and yielded growth curves which were straight lines on semi-log plots (r>0.99). 

The results obtained indicate that the best process conditions and plating procedure for boron deposition on a stationary 0.5-mil tungsten wire are as indicated in Figure 7. 

Metabolite/residue analysis. Milk, urine and plasma samples were first analyzed by a microbiological cylinder/plate procedure against M.luteus which has a limit of detection of 0.02 ppm. A sub-sample of the milk was prepared for this assay by a centrifugation step followed by a pH adjustment to 8.5. In addition, an HPLC/RAM analysis was conducted after treating another sub-sample with FTSH (10% formic acid, 30% trifluoroacetic acid, 2% sodium chloride, 2N hydrochloric acid) followed by centrifugation to precipitate the proteins. The supernatant was basified and concentrated by C-18 solid phase extraction (SPE) techniques. The HPLC conditions were Column - 20 cm x 4.8 mm C-8 Mobile-phase -linear gradient at 5%/minute from 90 10 O.IM pH 7 phosphate buffer methanol to 20 80 Detectors - UV operated at 214 nm and a radioactivity flow detector operated in the DPM mode. 

Preparation of Hg film electrode. The Hg film electrode, although possessing superior sensitivity characteristics, is more subject to irreproducible behavior than is the hanging Hg drop electrode. The following plating procedure is satisfactory.

Add 0.1 mL of the test microorganism suspension to 9.9 mL of the antimicrobial product and mix thoroughly. Immediately following mixing, plate 1.0 mL of the suspension, in duplicate, using the same medium and plating procedures as in Phase 1. Allow the mixture to stand for exposure period observed in Phase 1. After the exposure time has elapsed, plate 1.0 mL of the suspension, in duplicate, using the same medium and procedures as in Phase 1. Repeat this procedure until the number of samples required is completed.
