Light improved

Figure 11 The Spectra-Tech FT-80 grazing angle accessory. A typical accessory for grazing angle reflectance spectroscopy. A polarizer that transmits only P polarized incident light improves the sensitivity of the measurement.

Review ladders, railings, staircases, work platforms, and suitable lighting. Improve these for ease of plant operation and maintenance. 

Refinements in optical systems will aid in research in a variety of fields. For example, oceanographers already apply optics theory to the study of low-light organisms and to the development of techniques for conducting research in low light. Improved optical systems will likely have a positive impact on this and other research. 

Esters of cyclohexane polycarboxylic acids can be used as plasticizers for PVC to enable products with comparable mechanical properties to be obtained using less PVC. The use of these esters also produces formulations with increased stability to UV light, improved low temperature properties, lower viscosity, and improved processability, as well as reduced smoke on burning (15). 

The constants k- enable the improved representation of binary equilibria and should be carefully determined starting from experimental results. The API Technical Data Book has published the values of constants k j for a number of binary systems. The use of these binary interaction coefficients is necessary for obtaining accurate calculation results for mixtures containing light components such as ... 

During the production of mineral oils from vacuum distillates, one of the process steps, dewaxing , removes the high melting point materials in order to improve the oil s pour point. Dewaixing produces paraffins and waxes, the first coming from light distillates, and the second from medium or heavy distillates.
