Sourcing decisions components

IN-HOUSE OR OUTSOURCE The most significant sourcing decision for a firm is whether to perform a task in-house or outsource it to a third party. Within a task such as transportation, managers must decide whether to outsource all of it, outsource only the responsive component, or... 

Once a decision has been made to recover materials and/or energy, process flow sheets must be developed for the removal of the desired components, subject to predetermined materials specifications. A typical flow sheet for the recovery of specific components and the preparation of combustible materials for use as a fuel source is presented in Fig. 25-63. The light combustible materials are often identified as refuse-derived fuel (RDF). 

A valuable QRA result is the importance of various components, human errors, and accident scenarios contributing to the total risk. The risk importance values highlight the major sources of risk and give the decision maker a clear target(s) for redesign or other loss prevention efforts. For example, two accident scenarios may contribute 90% of the total risk once you realize that, it is obvious that you should first focus...

The first major task faced by planners is to assess the current state of the EHS system. Significant variability exists in the components of the EHS system. Planners must know the exact capabilities of each component. For the EMS dispatch system, how is dispatch performed and how can it be used to make triage decisions For EMS, how many ambulances and EMS providers exist How many can be requested from surrounding regions How are the destinations of EMS patients determined For EDs, how many can handle major trauma Minor trauma Intensive care patients How can a massive influx of patients be handled What alternate sites for care exist What transportation resources are available for distributing treated patients efficiently to maintain ED inflow and outflow What alternate shelter sources exist What preparations for mass decontamination are in place This survey must be continually repeated to ensure that the latest data are available to planners. 

The commodity vegetable oils can be classified in various ways. Some are byproducts so that decisions regarding their production are largely controlled by the nonoil component. Examples are corn oil and cottonseed oil. These are byproducts of cereal and fiber production, respectively. Also, rice bran oil is a byproduct of rice production. As a consequence, oil production is not the main economic factor that influences the areas cultivated by these crops. It is sometimes argued that soybean falls into this byproduct category and that the bean is grown as a source of protein with the oil as byproduct. It is true that the bean produces only 18% of oil against 79% of residual meal rich in protein, but the value of these two commodities is evenly balanced and there are times when the demand is oil-led and other times when it is meal-led. 

Every in vitro method should be detailed in the developer laboratories using Standard Operating Procedures (SOPs) covering all essential components and steps of the method. The SOP(s) should be sufficiently defined and described and should include the rationale for the test method, a description of the materials needed, such as specific cell types, a description of what is measured and how it is measured, a description of how data will be analyzed, acceptance and decision criteria for evaluation of data, and what are the criteria for suitable test performance. All limitations, e.g., lack of metabolic competences (presence of phase 1 and phase 2 biotransformation activities) or absence of critical transporters, should be included in the in vitro method description. In general, the in vitro method should not require equipment or material from a unique source. This may not be always possible for particular in vitro test systems or other components of the method in which case a license agreement between the provider and a recipient/user may be required. For complex and/or specialized equipment, the equipment specifications and requirements should also be described. Acceptance criteria for measurements carried out on the equipment should also be provided where applicable (e.g., for analytical endpoint determinations, linearity and limits of detection should de detailed) [2],... 

Carbonate cements are often among the dominant components of diagenesis and hence are of decisive importance in determining the reservoir quality of sandstone sequences. Despite this, the timing, the geochemical conditions of precipitation and dissolution, as well as the source and fate of these cements are not fully understood. In continental and near-shore sediments, cements commonly precipitate as calcretes and dolocretes in the vadose and phreatic zones, and attain a variety of mineral-ogical, textural and distribution patterns as well as elemental and isotopic compositions. These cements form lenses and layers of densely cemented... 

This is what we did at the American Cyanamid Research Center in Princeton, when we purified methyllycaconitine (an insecticidal plant alkaloid active on insect nicotinic receptors) from Delphinium plants. As reported by Dr. Chalmers in the Tuesday afternoon session, we were able to employ the in vitro cholinergic receptor binding assay to follow the active material present in small quantities on TLC plates. Results were available in a matter of hours. This type of strategy could expedite purifications of active materials from other natural sources. Also, knowing the mode of action of the insecticidal component at an early stage facilitated our decision to purify the active material.
