A method of evaluating the thermal focal length of nonlinear crystal via transmission spectrum of a swept cavity (TSSC) is presented. By recording the resonant point offset of the TSSC, the thermal focal length can be successfully measured. Furtherly, by distinguishing the absorption of ultraviolet (UV) laser and UV laser induced infrared absorption (ULIIRA), it is clear that the ULIIRA is the ...

One of the major challenges of successfully integrating radio frequency integrated circuits (RFIC) on silicon (Si) continues to be the poor performance of inductors. The low resistivity Si substrate is a cost-effective solution, however it is a major source of energy loss and limits the quality factor (Q) of inductors at high frequency. Conventional oxides introduce considerable stress due to t...

In this paper we propose a methodology to determine the structure of the pseudo-stoichiometric coefficient matrix kappa in a macroscopic mass balance based model. The first step consists in estimating the minimal number of reactions that must be taken into account to represent the main mass transfer within the bioreactor. This provides the dimension of kappa. Then we discuss the identifiability...

Fluorescence study on inclusion interaction of duloxetine in β-cyclodextrin shows significant increase in the fluorescence of duloxetine in the presence of β-cyclodextrin. The effects of pH and cyclodextrin concentration on the fluorescence spectra are reported. Fluorescence spectroscopy of the host-guest interaction between duloxetine and β-cyclodextrin shows formation of inclusion complex wit...

The temperature effect on denitrification rate of a two-sludge system has been studied. An industrial high-strength wastewater and an industrial by-product containing mainly methanol, as external carbon source, were used in this study. The maximum denitrification rate (MDR) was determined at six different temperatures: 6, 8, 10, 15, 20 and 25oC in batch mode. The temperature coefficient was fou...

In this work we present first principles study of the effect stoichiometric pairs antisite defects, V occupying Al site (V ) and (Al ), on electronic structure Seebeck coefficient Fe 2 VAlHeusler alloy. We show that introduction these defects opens bandgap VAl, changing it from semi-metal to semiconductor, which results in an increase for a range doping concentrations temperatures. calculated c...

There are more than 230 boron minerals which contain different amounts of boron oxide (B2O3) percentages. Magnesium borates are one of the boron mineral groups that have important properties of high elasticity coefficient, resistance to corrosion and high heat resistance. In this study, magnesium borate production is studied by hydrothermal synthesis method from a sodium borate mineral of tinca...

In this study, the results of the calibration of the complex activated sludge model implemented in BioWin software for the full-scale wastewater treatment plant are presented. Within the calibration of the model, sensitivity analysis of its parameters and the fractions of carbonaceous substrate were performed. In the steady-state and dynamic calibrations, a successful agreement between the meas...

A robust controller combining a feedforward compensator (for the measured disturbance) and a feedback RST controller is designed for the control of S. cerevisiae cultures. The controller is based on the linearization of Sonnleitner’s model allowing a simple transfer function model to be derived, which describes the relation between the ethanol concentration, the substrate feed and a measurable ...

The Re3As7- x In x solid solution was prepared for x ≤ 0.5 by heating the elements in stoichiometric ratios in evacuated silica tubes at 1073 K. It crystallizes with the Ir3Ge7 crystal structure, space group Im-3m, with a unit-cell parameter a ranging from 8.716 to 8.747 Å. The crystal structure and properties were investigated for a composition with x = 0.4. It is shown that indium substitutes...
