The Soil Conservation Service's (SCS) time of concentration calculation methodology is one of the most universally used methods when computing the time of concentration for a hydrologic basin. The approach is to break up the path of a drop of water into three distinct flow types: (1) sheet ...
a5cx-MEPP in US adults.b5cx-MEPP in Chinese children.c5oxo-MEHP in Chinese children. Each symbol is a central value (i.e. median or geometric mean). The size of the symbols is related to the study-specific sample size (N) and its weight in the time-trend calculation (see Statistical...
BACKGROUND: The ratio of the steady-state 24-hour area under the concentration-time curve (ssAUC24) to the MIC (AUC24/MIC) for vancomycin has been recommended as the preferred pharmacodynamic index. The aim of this study was to assess whether the calculated AUC24 (cAUC24) using the creati...
1. A new method for the determination of an immediate precursor of a substance occurring in the animal body is presented. 2. Calculations on the quantitative determination of the rate of turnover of a substance and their application to experiments involving the use of labeling agents are given....
Real Time Measurements of Diesel Particle Size Distribution with an Electrical Low Pressure Impactor Number concentration of particles emitted by combustion engines has recently attracted attention, due to the fact that particles of the size range found in tail pipe emissions are suspected of being ...
(1) Within a reasonable range, the fluorescence lifetime is independent of the often unknown fluorophore concentration. (2) FLIM can sense specimen properties not discernible in fluorescence intensity contrast. The fluorescence lifetime measured from a fluorophore in the specimen can be altered by ...
Japan wax is often bleached in the sunlight in the form of flakes or particles. In the midcourse of the bleaching process, they are usually melted and the concentration of colored materials unchanged in the particles is made uniform. This molten wax is, then, made again into particles, which...
Adding a third dimension results in three-way data, of which the combination of time and wavelength with temperature or with quencher concentration are the most well known. In this paper we concentrate on time-resolved spectra, however, many of the methods are also applicable for other ty...
In the following, we discuss how to realize such an inherent time crystal in experiments. We used erbium-doped yttrium orthosilicate (Er:Y2SiO5) with a concentration of 1000 ppm, corresponding to an average distance between erbium ions of approximately 4 nm, such that the average magnetic...
Light serves as the energy source for plants as well as a signal for growth and development during their whole life cycle. Seedling de-etiolation is the most dramatic manifestation of light-regulated plant development processes, as massive reprogramming of the plant transcriptome occurs at this time...
