Cumulative Subject solutions

Attention is drawn to a special feature of this Volume—inclusion of a generalized Cumulative Index to Volumes 1-10. It is believed that use of this Cumulative Index, in conjunction with the detailed Cumulative Subject Index to Volumes 1-5 (in Volume 6) and the detailed, individual Subject Indexes to Volumes 6-10, will afford the reader speedy access to sources of detailed information in the various Volumes. This solution to the indexing problem was chosen for economic reasons. 

The nature of OA interaction with SC lipids in vivo was of significant interest, particularly in light of the IR results above. Reflectance IR spectroscopy in conjunction with the use of a deuterated probe once again proved to be a valuable approach for the noninvasive evaluation of this enhancer in humans [153]. Prior to treatment, test sites on the inner ventral forearm of volunteers were cleansed with water, after which the subject remained at constant temperature and relative humidity, while three pretreatment spectra were collected. The experimental site on one arm was treated with a 5% v/v solution of perdeuterated oleic acid ( H-OA) in ethanol, while the control site, on the contralateral arm, was treated with ethanol alone. Both formulations were applied under occlusion for 16 hours posttreatment, the sites were swabbed clean with ethanol and then air-exposed for 2 hours to allow the occluded skin to dry. An ATR-IR spectmm of the dosed site was then obtained. This site was then tape stripped once and a second spectral examination was made. This sequential tape stripping and spectral acquisition was repeated -20 times in order to obtain an incremental spectral profile as a function of SC depth (defined by the cumulative weight of SC removed with tape stripping). IR spectra thus collected yielded the following information (a) the distribution... 

Nikiforoff [1949] has pointed out that although most soils are subjected to a slow erosion, whereby material is lost by solution or in suspension, and the A and B horizons are reformed continuously at successively lower levels, some soils are cumulative and are slowly buried by the accretion of material either by gravity from higher ground, by wind-transported material, or by volcanic ash. Such an accretion may be imperceptibly slow, but it can result in the formation of a B horizon in material that was previously part of an A horizon. The new deposit may or may not contain the same heavy mineral suite as the underlying soil.
