Conformations INDEX

Like VDA 6.1, AVSQ 94 does not include the requirements of ISO 9001. In this way issues of copyright are overcome, a practice shared by VDA and EAQF but not QS-9000. However, unlike VDA 6.1, AVSQ 94 follows the 20 elements of ISO 9001 with two additional elements, covering financial considerations and product safety. Those questions that go beyond ISO 9001 are marked and as every question is numbered it simplifies the evaluation process. A scoring method is employed to classify organizations in terms of a conformity index. Each question is awarded a point (0, 2.5, 5, 7.5, or 10), where 10 points means full compliance, 7.5 points means minor inadequacies, 5 points means inadequacies in application requiring improvement, 2.5 points means serious inadequacies in application, and 0 points is used for criteria not applied. Unfortunately all questions carry the same weight as no account of the impact of omission on product quality or customer satisfaction is included. [Pg.7]

One chemometric method used to monitor mixing involves comparing the spectrum for the unknown sample with that for one assumed to be homogeneous via the so-called conformity index , which is calculated by projecting the spectrum for the unknown sample onto the wavelength space of the spectrum or mean of spectra for the homogeneous sample. This procedure is similar to that involving the calculation of distances in a principal component space. [Pg.480]

In particular, it is recognized that when optimizing the treatment parameters in order to improve, e.g., the conformity index in conformal therapy or IMRT, other indices can change adversely, for example, the size of the irradiated volume, the integral dose, and the dose homogeneity throughout the PTV. [Pg.747]

As part of the processing within this system, molecules can be cleaned (chirality, ionization). Conformers can also be generated on-the-fly when performing the database search. In addition to conformations, indexing of a database can be done by adding pharmacophore sites. Partial match of the hits on a pharmacophore query is allowed. The pharmacophore search hits are ranked using a fitness function. [Pg.35]

Near-infrared spectroscopy was proposed as an alternative to several compendial test methods. As an example, ampicillin trihydrate was used to demonstrate that in total, eight quality criteria could be checked and its conformity index calculated.Additional che-mometrics for quality control were developed by the same group. Their strategy was used to distinguish differences in mean particle size of various lactose samples and to study the effectiveness of a blending process for homogenous mixture preparation. [Pg.3383]

Although the conformity index should provide a measurement of the total quality of the product, including the adherence to moisture specifications, Plugge and van der Vlies also developed a quantitative calibration for water. With Karl Fischer as reference, their calibration covered the range from 7.1 to 11.6% moisture and used 1642 and 1930 nm to give suitable linearity. [Pg.68]

Plugge and van der Vlies have discussed the conformity index (Cl) for NIR analysis of ampicillin trihydrate [12,13]. The Cl is a metric used to determine the degree of conformity of a sample or batch with standards of known and acceptable quality. To use the Cl, reference spectra are first collected and baseline-corrected using a second-derivative or multiplicative scatter correction (MSC) spectrum. At every wavelength across the spectrum, the average absorbance and standard deviation are calculated for the baseline-corrected reference spectra, resulting in an average spectrum and a standard deviation spectrum. [Pg.60]

Sinee the poorest performanee of the assembly distribution would oeeur when shifted, Cpk values rather than Cp values are better design targets. The Cp value ean be used as a target for the assembly based on the severity of applieation and minimum failure eost of 0.01% of the total produet eost as determined by the Conformability Map. If only eapable solutions are to be generated, whieh have a minimum proeess eapability index of Cp =1.33 (or 30 ppm) for both eomponent and assembly distributions, then the number of eomponents in the assembly staek ean be as low as three using the proposed statistieal model (Harry and Stewart, 1988). The overall requirement is... [Pg.118]

To help the reader select the appropriate data resource, an index precedes Sections 4.3 through 4.8. The index provides the source number within the section and the following set of data elements for each source title, industry, number and type of records, and data boundary. Appendix C contains additional information about the data elements presented in each data resource. It can also be used to help identify the resources which may provide data for a CPQRA. A discussion of the Appendix C Matrix and an explanation of data elements indexed is presented. After examining Appendix C and the pattern of data elements contained in the data resources, it is evident that equipment reliability data have been published in a variety of formats, often without any apparent effort to conform to a recognized standard for data specification. The CCPS Taxonomy and the raw data collection requirements in Chapter 6 present the basis for reliability data specification in future literature. [Pg.29]

Synthetic, nonionic polymers generally elute with little or no adsorption on TSK-PW columns. Characterization of these polymers has been demonstrated successfully using four types of on-line detectors. These include differential refractive index (DRI), differential viscometry (DV), FALLS, and MALLS detection (4-8). Absolute molecular weight, root mean square (RMS) radius of gyration, conformational coefficients, and intrinsic viscosity distributions have... [Pg.562]

The index consists of two parts. Part I contains entries referring to the conventional names of compounds as they appear in the preparations of this volume followed by the systematic names in brackets, if the nomenclature differs The bracketed names conform to the systematic nomenclature adopted by the Chemical Abstracts Service starting with Chemical Abstracts Volume 76 (1972) Part II of the index contains entries of the subjects of this volume with compound names in a reversed order of Part I... [Pg.137]

Differential refractive index detectors measure the difference in refractive index between the solvent and the eluting polymer solution. The DRI can be used with almost any polymer-solvent combination, as long as the incremental increase in refractive index of the polymer solution with increase in polymer concentration is sufficient. Although a large number of differential refractometers are available in the market,167168 they usually conform to three main types, namely... [Pg.341]
