Quality independence

There are many misconceptions associated with the CLP analysis. For example, many environmental professionals believe that because of the prescriptive protocols and unambiguous data evaluation guidelines, the CLP methods produce better quality data than their SW-846 equivalents. In fact, some of the CLP methods may be less accurate than their SW-846 counterparts. For example, the calibration requirements of the CLP SOW for Organic Analysis (EPA, 1999d), are not as stringent as these of the equivalent SW-846 methods. In addition, matrix effects have an equal impact on data quality independent of the analytical method used. The CLP produces better quality data only in terms of better consistency between laboratories, more thorough documentation, and uniform QC acceptance criteria. [Pg.59]

There are two important factors in determining the cost of the refold step. The first is the cost of labor, utilities, equipment, and raw materials to produce the refolded protein. The second is the purifiability of the protein from the other components of the environment in which it is refolded. This is not a precisely definable function of the measurable properties of the refolded protein, but must be evaluated by its downstream performance in the process with respect to yield and quality. A further complication arises in that the process may not be fully developed and therefore changes in the process will occur that will improve both yield and quality, independent of the refold conditions. Bearing these conditions in mind, we present cost information in this section on the basis of the cost to refold the protein. Costs associated with its purifiability are not presented. [Pg.214]

In addition to the above-mentioned polyesters on the basis of renewable resources the industry will use their scientific and most of aU technical capacities in a growing manner to synthesize degradable polymers, polyesters, and polyamides like Bionolle, BAK, Eastar Bio, Materbi, Eastman on a petrochemical basis. These polymers will be considered to be low price materials on the market and to take the striven-for disposal concepts into account and show the advantages of synthetic materials referring to constant quality independent from seasonal and territorial fluctuations and the low costs in their best light. [Pg.212]

Fuzzy goal programming uses the ideal values as targets and minimizes the maximum normalized distance from the ideal solution for each objective. An ideal solution is the vector of best values of each criterion obtained by optimizing each criterion independently ignoring other criteria. In this example, ideal solution is obtained by minimizing price, lead-time, and quality independently. In most situations, the ideal solution is an infeasible solution since the criteria conflict with one another. [Pg.339]

Many applications such as multimedia need some network guarantees to deliver a certain level of quality independent of the current or future network state. For example, to deliver a high-quality video, the network should provide a video connection with a guaranteed bandwidth of, e.g., 4 Mbps. Thus, a network should provide a certain level of quality of service (QoS). QoS is characterized by QoS parameters such as bandwidth, delay, and delay jitter. The user/application negotiates a QoS contract with the network by specifying QoS parameters that the network will guarantee during the lifetime of a connection. [Pg.53]

Nevertheless, the interpretation of differences between the two batches could be very difficult. How should a change in the pH value (e.g., from 7.9 to 8.2), or in the plant available fractions of nutrients in relation to their total content be interpreted A more readily applied result could be obtained from bioassays, since any decrease of the germination rate of the seed or any reduction of plant growth (production of green plant biomass) could easily be declared as a loss of compost quality, independent of the chemical composition. [Pg.95]

This work particularly tries to curtail the second step of the above and to make the report quality independent of reporter s skill as much as possible. [Pg.4]

For certain types of detectors, D is inversely proportional to the root of the detector area and the term D is more characteristic of this class of detectors it allows comparison of detector quality independently of size (Jones, 1959). Expressing it in units of root hertz,... [Pg.254]

It is noteworthy, however, that traces of sulfur can have beneficial effects on the anti-wear resistance of fuel injection pumps. It is thus undesirable to reduce the sulfur content to extremely low values unless additives having lubricating qualities are added. Independently from total sulfur content, the presence of mercaptans that are particularly aggressive towards certain metal or synthetic parts is strictly controlled. The mercaptan content is thereby limited to 0.002% (20 ppm) maximum. The analysis is performed chemically in accordance to the NF M 07-022 or ASTM D 3227 procedures. [Pg.251]

This type of contract requires the operator to pay a fixed amount to the contractor upon completion of the well, while the contractor furnishes all the material and labour and handles the drilling operations independently. The difficulty with this approach Is to ensure that a quality well Is delivered to the company since the drilling contractor will want to drill as quickly and cheaply as possible. The contractor therefore should guarantee an agreed measurable quality standard for each well. The guarantee should specify remedial actions which will be implemented should a substandard well be delivered. [Pg.62]

In the simplest case, for a pressure drawdown survey, the radial inflow equation indicates that the bottom hole flowing pressure is proportional to the logarithm of time. From the straight line plot ot pressure against the log (time), the reservoir permeability can be determined, and subsequently the total skin of the well. For a build-up survey, a similar plot (the so-called Horner plot) may be used to determine the same parameters, whose values act as an independent quality check on those derived from the drawdown survey. [Pg.223]

The detection sensitivity of radiography is related among others to the properties and quality of industrial x-ray film systems. Changes of the products, variations due to different emulsions and combinations of products of different manufacturers can influence the decisive properties of film systems as classified in EN 584-1.To ensure the quality of industrial x-ray film systems a system for quality assurance open to all interested parties is proposed which is based on periodical round robin tests and quality controls of the manufacturer or an independent third party institution. [Pg.555]

A suggested middle ground is a quality server provider who can deliver the features you need Load your pages on the Server and get your own domain, "www.eompany.com", that means you operate a virtual server Your presence is then quick and inexpensive to achieve. You also remain flexible and independent, so can always transfer to another server if you decide to change providers for any reason. [Pg.978]

All static studies at pressures beyond 25 GPa are done with diamond-anvil cells conceived independently by Jamieson [32] and by Weir etal [33]. In these variants of Bridgman s design, the anvils are single-crystal gem-quality diamonds, the hardest known material, truncated with small flat faces (culets) usually less than 0.5 nun in diameter. Diamond anvils with 50 pm diameter or smaller culets can generate pressures to about 500 GPa, the highest static laboratory pressures equivalent to the pressure at the centre of the Earth. [Pg.1958]

A final component of a quality control program is the certification of an analyst s competence to perform the analysis for which he or she is responsible. Before an analyst is allowed to perform a new analytical method, he or she may be required to successfully analyze an independent check sample with acceptable accuracy and precision. The check sample should be similar in composition to samples that the analyst will routinely encounter, with a concentration that is 5 to 50 times that of the method s detection limit. [Pg.708]

A good example of a prescriptive approach to quality assessment is the protocol outlined in Figure 15.2, published by the Environmental Protection Agency (EPA) for laboratories involved in monitoring studies of water and wastewater. Independent samples A and B are collected simultaneously at the sample site. Sample A is split into two equal-volume samples, and labeled Ai and A2. Sample B is also split into two equal-volume samples, one of which, Bsf, is spiked with a known amount of analyte. A field blank. Dp, also is spiked with the same amount of analyte. All five samples (Ai, A2, B, Bsf, and Dp) are preserved if necessary and transported to the laboratory for analysis. [Pg.712]

They are the only devices that are independent of the operating system, as the breaking eapacily is dependent mainly on the material and contour of the contact structure and the quality of the vacuum. [Pg.644]

You should consider obtaining internal and external quality assurance reviews of the study (to ferret out errors in modeling, data, etc.). Independent peer reviews of the QRA results can be helpful by presenting alternate viewpoints, and you should include outside experts (either consultants or personnel from another plant) on the QRA review panel. You should also set up a mechanism wherein disputes between QRA team members (e.g., technical arguments about safety issues) can be voiced and reconciled. All of these factors play an essential role in producing a defendable, high-quality QRA. Once the QRA is complete, you must formally document your response to the project team s final report and any recommendations it contains. [Pg.28]

First, the structure should explain the data. Apart from the energy or target function value returned by the refinement program, this check can be performed with some independent programs (e.g., AQUA/PROCHECK-NMR [90], MOLMOL [91]). The analysis of the deviations from the restraints used in calculating the structures is very useful in the process of assigning the NOE peaks and refining the restraint list. As indicators of the quality of the final structure they are less powerful, because violations have been checked and probably removed. A recent statistical survey of the quality of NMR structures found weak correlations between deviations from NMR restraints and other indicators of structure quality [88]. [Pg.271]

In addition to fulfilling the in-house requirements for quality control, state and local air monitoring networks which are collecting data for compliance purposes are required to have an external performance audit on an annual basis. Under this program, an independent organization supplies externally calibrated sources of air pollutant gases to be measured by the instrumentation undergoing audit. An audit report summarizes the performance of the instruments. If necessary, further action must be taken to eliminate any major discrepancies between the internal and external calibration results. [Pg.224]
