Testing changes

Paired t-tests Changes in constitutive calcitonin receptor responses with 100 nM AC512. [Pg.229]

Testing change in attitude interviews, observation and valid psychological tests. [Pg.306]

To provide a measure of the quality of performance of individual laboratories. By regular testing, changes in performance can be studied. [Pg.118]

Standard fatigue tests normally require extended periods of time to complete regardless of the type of stress/strain used. Accelerated fatigue tests change some conditions of the test in the hope of reaching the same end point in less time. Potential means of accelerating the tests include changing factors such as the temperature, frequency, chemical environment, levels of stress or strain, or the addition of stress concentrators. [Pg.536]

In agreement with (6), regression of dye concentration data measured at the beginning of the test makes it possible to relate the dye conversion rate to the conditions set in the reactor at the beginning of the test. Changing the initial conditions of the tests enables the evaluation of kinetic parameters. [Pg.113]

Karon B, O Grady P. Intellectual test changes in schizophrenic patients in the first six months of treatment. Psychother Theory Res Pract 1969 6 88-96. [Pg.98]

The changes and version control section will include information concerning purpose, responsibilities, and testing. Changes in the operating system and/or in Excel (e.g., new version and other significant changes in the spreadsheet) have to be documented, reviewed, and approved. The documentation will include ... [Pg.289]

The amount of sample needed will depend on the rheometer and test fixture that are used. Ideally, there should not be excess sample (e.g., below or above the inner cylinder or outside the upper plate). Usually, sample below or above the inner cylinder does not contribute significantly to the results because of its smaller contact area compared with that of the wall of the cylinder. For steady rotational viscometry, it is often critical to cut the sample outside the upper plate. Thus it is also recommended to do so in dynamic tests. Changes in sample volume that often occur during gelation must also be considered. [Pg.1207]

The increase in ILSS for the epoxy-sized fibers over the bare fibers is 12.4%, approximately 50% of the increase observed in the interfacial shear strength as measured by ITS testing. Changes in the failure mode at the fiber-matrix interface may account for the differences. The sized fibers produced large matrix cracks that grew quickly to catastrophic size under load. This would tend to limit the increase in composite shear properties if at every fiber break in the tensile surface of the coupon a matrix crack was created. The presence of these matrix cracks... [Pg.524]

X-ray Analysis with Electron Microscope. Knowing what elements are present in the voile fabric could conceivably help isolate the dyestuff used as the colorant on this material. Also, since the washing test changed the color so dramatically and since the color of the wash water suggested that some substance had been removed from the fabric, the tested specimen could show a removal of certain elements, which might contribute to knowledge about the dyeing of this fabric. [Pg.277]

Q6 Examination of a blood film is a routine diagnostic test. Changes in types and numbers of the cells can give important information on the patient s condition. [Pg.251]

Flammable Liquid SAFETY PROFILE Poison by intraperitoneal route. Moderately toxic by intravenous and subcutaneous routes. Mildly toxic by inhalation. An experimental teratogen. Human systemic effects by inhalation CNS recording changes, hallucinations or distorted perceptions, motor activity changes, antipsychotic, psychophysiological test changes, and bone marrow changes. Experimental reproductive effects. Mutation data reported. A human eye irritant. An experimental skin and severe eye irritant. [Pg.1351]

Monitor CV (blue-yellow) with D-15 or Famsworth-MunseU 100-hue test. Changes should be reported to the prescribing physician for consideration of concomitant cardiac digitalis toxicity. [Pg.749]

Repeated exposures to APFO, the most widely used salt of PFOA, produced liver, kidney, pancreas and testes changes, anemia, and cyanosis. Tests in male rats demonstrated weak tumorigenic activity based on an increased incidence of benign testicular, pancreatic, and liver tumors. Tests in animals demonstrate no developmental toxicity. [Pg.1940]

Do not assume that the combination of variables that are best for determining clusters or treatments on one sampling day will be the most appropriate for every sampling day. As the structure and function of the multispecies toxicity test change over time, so will the important variables. [Pg.67]

Figs. 11 to 13 illustrate the temperature dependence of strain at failure (in bending test), change in surface roughness with additional traffic exposure period, and skid resistance of the asphalt mixtures using powdered rubbers, respectively. The advantages of the asphalt mixtures are improvements in skid resistance and abrasion resistance, a reduction in traffic noise and a prevention effect of freezing. [Pg.148]

A scientist determines how hard the tap water is in the laboratory, using an EDTA titration. If the pipes in the building are old and some rust dissolves into the tap water, how will the results of the test change ... [Pg.146]
