Industry modelling

The laboratory tubular centrifuge is similar to the industrial model. It operates with a motor or turbine drive at speeds to 50,000 rpm, generating 65,000 G at the latter speed in the 4.5 cm diameter bowl. The nominal capacity range is 30—2400 cm /min. This centrifuge is uniquely capable of separating far finer particles than any other production centrifugation equipment except the botde centrifuge. It is widely used in the production of flu vims. 

The automotive sector s quality assurance standard QS 9000 (1998) suggests a concurrent high level model, as opposed to the sequential model from BS 7000 (1997). This is shown in Figure 5.7. The automotive industry in particular has embraced the use of concurrent engineering models for product development, and this is reflected in the standards which facilitate their quality assurance programmes. A concurrent industrial model from the automotive sector will be discussed later.

Sodium valproate was not sufficiently volatile for mass spectral analysis. The mass spectrum of valproic acid as shown in Figure 5 was obtained using an Associated Electrical Industries Model MS-902 Mass Spectrometer with the ionization electron beam energy at 70 eV. High resolution data were compiled and tabulated with the aid of an on-line PDP-11 Computer.

The single roll crusher shown in Figure 2.13 consists of a toothed crushing roll which rotates close to a breaker plate. Figure 2.14 is an illustration of an industrial model. The material is crushed by compression and shearing between the two surfaces. It is used extensively for crushing coal. 

Partial or complete re-validation is another precedented approach to method transfer. Those variables described in method validation guidance documents (ICH Q2B, 1996 USP, 2012c) that are likely to be impacted by method transfer, should be assessed and documented (transfer or validation protocol). Agut et al. (2011) indicated that, in the changing industry model with the increased outsourcing of R and D activities (alliances, outsourcing, etc.), method re-validation may constitute, in some cases, an efficient approach when the transfer is performed from the Analytical Development Laboratory of an external partner who does not share exactly the same environment (validation standards, analytical culture or traditions , equipment, etc.). ...

The full-scale industrial experiment demonstrated the feasibility of a convenient, nonintrusive aconstic chemometric facility for reliable ammonia concentration prediction. The training experimental design spanned the industrial concentration range of interest (0-8%). Two-segment cross-validation (test set switch) showed good accnracy (slope 0.96) combined with a satisfactory RMSEP. It is fully possible to further develop this pilot study calibration basis nntil a fnll industrial model has been achieved. There wonld appear to be several types of analogous chemical analytes in other process technological contexts, which may be similarly approached by acoustic chemometrics.

Some simple but powerful solutions have come from this industrial model of quality assurance. For example, just the removal of concentrated potassium chloride solutions from hospital wards can prevent a toxic dose of potassium from being accidentally injected intravenously. Making the color of the tubing different may prevent epidural lines and IV lines being interchanged so that medication intended to go into a vein does not go into the epidural space,or vice versa. 

A long, hollow, cylindrical bowl is suspended by a flexible spindle and driven from the top as shown in Figure 13. Axial ribs in the bowl ensure full acceleration of the liquid during its short time in the bowl. Feed is jetted into the bottom of the bowl and clarified liquid overflows at the top, leaving deposited solids as compacted cake on the bowl wall. The clarifying performance of the bowl is reduced as the deposited cake decreases the effective outer radius of the bowl in accordance with equation 11. Consequently, cake capacity of the industrial model is limited to 0.1—10 L. For liquid—liquid separation, the interface position (eq. 26) is determined by selection of ring-dam diameter or by the length of a hollow nozzle-type screw dam.

The industrial model of vaccine development is best described in a report requested by Congress and the Deputy Secretary of Defense. The study, which was asked to report on the acquisition of biological warfare defenses, drew heavily on the views of the expert panel that conducted it. The report argued that (1) threats of biological warfare and endemic infectious disease are high consequence (2) vaccines are the lowest-risk, most-effective response to these threats ...

The goal of this chapter is to provide a brief overview of standard engineering methods for process development and scale-up and discuss their applicability to the pharmaceutical industry. Model-based design methods and their impact on optimization, scale-up, and process control are discussed. The state of the art is contrasted to a realistic desirable state where these methods become part of a new standard of technological articulation. 

Far from being unique to the aerospace industry, model-based design and optimization are standard practice across a great many industries, including microelectronics, petrochemicals, and automobiles. All of these industries share four characteristics ... 

At a minimum, the modeling capability must encompass industry models to reflect the nation s heavy industry at the core of the fossil energy and materials sector (electric power, petroleum refining, basic chemicals). This industry core generates the nation s electricity, refines the nation s petroleum products, and transforms the nation s chemicals into useable endproducts. New trends in production costs, resource use, and environmental quality will generally be influenced significantly by what happens in this heavy industrial core.
