BACKGROUND Topical application of oils and oil-based formulations is common practice in skin care for both adults and infants. Only limited knowledge however is available regarding skin penetration and occlusive potential of oils and common methods for measuring skin moisturization fall short when it comes to the moisturizing effect of oils. OBJECTIVE In(More)
Leaves of the C3 plants Brassica oleracea L., Datura suaveolens Humb. & Bonpl. ex Willd., Helianthus annuus L. and Nicotiana tabacum L. with open stomata were exposed in a leaf chamber in the dark to CO2 concentrations varying from 1 to 20% in air. When they were transferred back into CO2-free air, CO2 was rapidly released. It originated from dissolved CO2(More)
In the present study, 28 hemophiliacs substituted continuously and 5 hemophiliacs who had received almost no blood products were investigated. Cells of OKT 3+, OKT 4+, and OKT 8+ subsets were counted. Percoll separated fractions of peripheral blood mononuclear cells were examined by morphological criteria and were tested for NK cell activity. We found that(More)
In recent years, there have been continuing efforts to understand the effects of baby skin care routines and products on the healthy development of baby skin. Such efforts aim ultimately to determine the best infant skin care practices. The pediatric and dermatologic communities have not reached consensus on what constitutes an appropriate cleansing(More)
Diaper dermatitis (DD) is one of the most common skin conditions in neonates and infants, with a peak between the ages of 9 and 12 months. Appropriate skin care practices that support skin barrier function and protect the buttocks skin from urine and feces are supposed to be effective in the prevention of DD. Despite many recommendations for parents and(More)
With the trend from micro- to nanoelectronics the control of production deviations can not keep pace with the reduction of the absolute sizes of semiconductor devices. This results in an increased number of circuits beyond specification. The presented symbolic methods for reducing behavioral models with parameter variations assist designing and optimizing(More)
The aim of this work is to assist designing of robust circuits to minimize the amount of defective circuits and therefore to increase the yield of production. The Fraunhofer ITWM considers electronic circuits at system level using its EDA software Analog Insydes, which allows analysis and symbolic approx ima tion of nominal analog circuits. The software now(More)
