The variability of pulse wave was found and discussed recently. The cross-correlation of variability of the parameters of pulse wave was studied in this paper. We found that the variability of the features in time was closely related. However, the variability of the features in time had little correlation with that of the amplitude features of pulse wave. The complexity of the variability of these...
Determination of optimal sampling transects and pollutants for river sediments are essential and valuable. To determine if the concentration of some metals were highly correlated, correlations between heavy metals (As, Pb, Cd, Cr, Hg, Cu, Ni and Zn) were analyzed using statistic analysis software (SAS) based on monitoring data of heavy metals along the whole watercourse sediments of Dagu River. To...
In order to understand the variation of turbidity in the water column of Liuxihe reservoir, the relations of turbidity and hydrology status is analyzed, which shows a high relationship between them. A model about total suspended matter (TSM) is proposed to study TSM and related hydrology factors (inflow and outflow volume) quantitatively. In order to make the model close to the real state, the particle...
On-line monitoring of penicillin cultivation processes is crucial to the safe production of high-quality products. Multi-way principal component analysis(MPCA), a multivariate projection method, has been widely used to monitor batch and fed-batch processes. However, when MPCA is used for on-line batch monitoring, the future behavior of each new batch must be inferred up to the end of the batch operation...
Data from 3 monitoring stations in the upper reaches of the Daling River from 1985 to 2007 reveal an obvious increasing trend in the concentrations of NH4-N, NO2-N and NO3-N. The average annual concentrations of NH4-N, NO2-N and NO3-N increased from 0.69 mgL-1, 0.006mgL-1, 1.14 mgL-1 in 1985 to 3.01 mgL-1, 0.210 mgL-1, 6.57 mgL-1 in 2007. The highest concentrations of NH4-N, NO2-N and NO3-N during...
In recent years, much attention has been paid to the problem of farmland soil contamination by heavy metals in China. Cadmium (Cd) is an important heavy metal which can cause adverse ecological effects, in particular, can be easily accumulated by rice plants. On the basis of determining the concentrations of Cd in 303 farmland soil samples from the rice producing area in the Luxian County, Sichuan...
Extra-corporal Circulation Support Systems (ECCS) are used in cardiac surgery on a daily basis. Surgeons and perfusionists supervise patients' vital signals such as heart rate or blood pressure and ensure secure and errorless operation of the ECCS. Latest developments clear the way to use an ECCS for emergency circulatory resuscitation in non-clinical environments, even when trained staff is sparse...
