Manufacturing readiness levels

Coating systems are available in the form of a liquid paint In order to be apphed efficiently, a minimum viscosity level is required. This is achieved with the use of an appropriate solvent, which is either included from the manufacture (ready to use) or it is added at the appUcation site [3,9,55]. 

The quantity, quality and purity of the template DNA are important factors in successful PGR amplification. The PGR is an extremely sensitive method capable of detecting trace amounts of DNA in a crop or food sample, so PGR amplification is possible even if a very small quantity of DNA is isolated from the sample. DNA quality can be compromised in highly processed foods such as pastries, breakfast cereals, ready-to-eat meals or food additives owing to the DNA-degrading action of some manufacturing processes. DNA purity is a concern when substances that inhibit the PGR are present in the sample. For example, cocoa-containing foodstuffs contain high levels of plant secondary metabolites, which can lead to irreversible inhibition of the PGR. It is important that these substances are removed prior to PGR amplification. Extraction and purification protocols must be optimized for each type of sample. 

A patented process involves pre-reacting the hydrocarbon plasticizer with a small amount of molten sulfur at the manufacturing plant to form a concentrate which is shipped to the work site. At the site it is mixed with the heated aggregate and additional sulfur to reach the desired binder level fine filler is added, if necessary, and the molten mass is mixed and ready... 

Auditing the contract API manufacturer is important in order to assess the quality systems used to determine the integrity and quality capability of the firm, to determine their level of GMP compliance, and assess the level of resources available to meet preapproval inspections (PAI) and GMP compliance readiness. 

Ready to Sterilize (RtS) Typically components are washed, then rinsed with Water For Injection (WFI) to reduce bioburden and endotoxin levels, lubricated with silicone oil, and finally packaged in a classified area (Classes 100-10,000) in Tyvek bags that can be steam sterilized by the drug or device manufacturer before use. Alternately polyethylene bags may be used if the end user is utilizing gamma radiation for sterilization. 

Subam was the first manufacturer to offer fuUy recyclable PP/TPE bumpers for all car models. To recycle, the bumpers are chopped into sections and placed between rollers rotating at different speeds. This removes 99% of paints and coatings. The sections are then re-stabihzed and granulated, ready for re-use. Similarly, Nissan aims for 100% bumper-to-bumper recycling of PPE/PA. Fiat has a policy of 100% recycling its TPO bumpers into automotive parts that do not demand similar level of performance, viz. air ducts, liners, etc. The PP battery cases are being recycled as fender liners. 

The inputs to a manufacturing system include production orders, raw material and labor, disturbance inputs, and ccmtrolled inputs. Production orders specify the quantities of various jobs to be processed and the dates on which these jobs are due. Disturbance inputs include machine failures and labor outages, over which the scheduler has little influence. Controlled inputs include scheduling, maintenance, and overtime decisirms, which the scheduler can regulate within bounds. The state of a manufacturing system defines the levels for all completed and partially completed jobs, the status of all machines, the availability of labor, and the inventories for aU materials. Outputs of the manufacturing system may be defined as any portion of the state - for example, the inventory levels of all jobs ready for shipment on a specified date as shown in Fig. 1 (Chryssolouris 2006).
