Sinusoidal response can evaluate the tracing result with different frequency and amplitude, and its control result indicates the response performance and the control accuracy, so the sinusoidal signal is chosen as the input signal to analyze the system parameter sensitivity of the HIVC force control system.
The purpose of this study is: (a) to characterize the mineralogical and trace metal composition of streambed sediments, (b) to evaluate the level of trace element contamination in sediments in comparison to local soils and Sub-Saharan Africa soil composition (c) to identify the sources of trace elements based on spatial distribution.
Thus, a number of works have been presented by researchers to evaluate the bounds and trace bounds for the solution of the ARE (see [6 16]).
Thus, a number of works have been presented by researchers to evaluate the bounds and trace bounds for the solution of the (ARE) [6 12].
In the present study, we evaluate the influence of trace element (TE) concentration in sediments and physico-chemical properties of water on sediment microbial communities in water streams adjacent to the Copper Smelter Complex Bor (RTB Bor, Serbia).
In this work, a sequential extraction scheme was used to evaluate the mobility of trace elements in sediment and to reveal any potential contaminants that may be mobilized from the dredged sediments.
In order to evaluate the possibility of tracing dissolved inorganic carbon (DIC) derived from calcite dissolution under open system conditions, controlled laboratory experiments using stable carbon isotopes were conducted in a specially designed reaction chamber with constant pH monitoring.
To evaluate the mobility of trace elements and to identify the potential contaminants from the dredged sediments, a sequential extraction scheme was used to partition trace elements associated with the sediments from the local aquifer and the dredged sediments into five fractions: exchangeable, acidic, reducible, oxidizable, and residual phases.
Synchrotron radiation induced confocal micro X-ray fluorescence analysis (SR μ-XRF) together with quantitative backscattered electron imaging (qBEI) have been used for the first time to evaluate the spatial distribution of the trace elements Zn, Sr and Pb in bone tissue.
The purpose of this study was to evaluate the possible associations between trace elements and idiopathic intractable epilepsy (IIE) by comparing the levels of Se, Zn, and Cu between patients with IIE and healthy children.
Float-sink separation has been used in a number of studies to evaluate the partitioning of individual trace elements between organic-rich and mineral-rich fractions of coal samples, based mainly on correlations between element concentration on factors such as separation density and ash yield.
