These values were determined from the slope of the plot of Ip versusυ (not shown) for PANSA/PVP-AgNPs and PANSA/PVP-AgNPs/CYP2E1 respectively from data received from CV studies carried out in PBS buffer solution.
The surface concentrations for PANSA/PVP-AgNPs and PANSA/PVP-AgNPs/CYP2E1 were calculated using the Brown-Anson method (Equ. 2) where the respective values were determined to be 1.57 x 10-6 mol cm-2 and 2.03 x 10-6 mol cm-2 from plots of Ip as a function of (not shown) using from data obtained from CV analyses.
Electrocatalytic Reduction of Isoniazid.
Plot of reduction current density against INZ concentration.
The voltammograms (Figure 10, 11 and 14) each illustrate a well-defined reduction peak confirming the reduction of INZ by the Au/PANSA/PVP-AgNP/CYP2E1 nanobiosensor in deoxygenated buffer solution.

Each data point is calculated from 2500 instantaneous hot wire data.
Data Reduction and Measurement Uncertainties The transient liquid crystal technique was used in this study to acquire and reduce heat transfer data.
In the calculation of the uncertainties for Nusselt number, the data reduction computer program was used to compute the sensitivity coefficients of each temperature variable and time.

After completion of adding NaBH4 into the FeSO4.7H2O suspension, the mixture was further stirred for another 1 hour to allow for complete reduction.
Black-colored precipitate of ZVI can be seen as a result of the reduction.
It might also require more time to allow for complete reduction of ZVI.
This shows that there was a successful reduction of FeSO4.7H2O to form ZVI using NaBH4.

It comes from the carbothermic reduction of quartz at high temperature (2000ºC approximately) in an electrical arc furnace.
For PV applications, the level of silicon purification is not as stringent as that of the microelectronics case, giving room to process simplifications that can lead to cost reductions.
Others A direct carbothermic reduction from selected quartzs and carbons has also been investigated, with the philosophy to avoid not only the chlorosilanes but also the metallurgical intermediate step [[] E.
This is the case of using as volatile compound silicon tetrafluoride, produced from a by-product of the fertiliser industry [5], performing an aluminothermic reduction of silicon [[] BN.
A crystalline Si reference technology is analysed, whose cost structure is based on direct manufacturing cost data provided by industrial partners.

In [15, 16], the authors showed the importance of pilot hole on delamination reduction when using core drills.
A thrust force reduction of 25% to 50% can be found when comparing holes with and without pilot hole.
This work is concerned with the reduction of this type of delamination.
During drilling, axial thrust forces were monitored with a Kistler 9257B dynamometer associated to an amplifier and a computer for data acquisition.
Yet, a reduction in feed rate also has a consequence on temperature build-up, increasing the risk of thermal damages.

Note: The energy consumption data of the train's air conditioning, lighting and other auxiliary system in the research have been included in the vehicle energy consumption
The data in 2009 obtained by the survey become the base of inertial model and through prediction for the parameters of calculation model, the prospective prognosis of traffic energy consumption and carbon emissions in Beijing has been carried out
(7) is the total station energy consumption (million kwh); is the station energy consumption of line i (million kwh); , , is respectively the number of station of ground open system, underground open system and platform door system; , , is respectively the average energy consumption of each kind of station According to the statistical data in 2009 provided by Beijing Subway Operation Company, the average energy consumption per month for the three classification station in air-conditioning month(June to September) and non-air-conditioning month were obtained, as shown in table 7.
If the low-carbontraffic policies, such as limitation of the car amount, adjustment of travel mode, reduction of rail transit energy consumption and trip time of car, are implemented, transport energy consumpation and carbon emission can be reduced up to 16%, which will be benefit to the development of low-carbontraffic.

At the same time, the errors in passes 11-14 are caused by overcooled ends of the rolled product, which were not taken into account in the simulation, due to lack of actual data temperature for these areas.
In addition, partial reduction of pause time (up to 29 s and 20 s instead of 58 s and 30 s respectively) between the passes is proved by actual data when rolling 4.5×2585mm thick plates from 150mm thick slab in mill 3200 at Trametal.
By reducing pause time, it was possible to raise the metal temperature in the passes, resulting in the rolling force reduction.
Comparison of the reduction of rolling force due to the increase in metal temperature along the pass and the reduction of the time of pause by alternative is shown at Fig. 4 Fig. 4.
Summary In the paper, there has been checked the developed mathematical model based on actual data obtained at mill 3200 (Trametal).

Introduction Nowadays, due to unique electronic structure and good conductivity molybdenum carbides (MoCx) are widely used as catalysts in various reactions: nitrogen reduction reaction (NRR), CO2 reduction reaction (CO2RR), hydrogen evolution reaction (HER), oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) [1].
Molybdenum carbides can be synthesized by various techniques, including calcination [4], tuning carburization atmosphere and temperature of the precursor [5], pyrolysis [8], chemical vapor deposition (CVD) [13, 14], through the first reduction reaction and the following carbonization process [15], mechanochemical synthesis [16], using a temperature programmed reaction procedure [17] etc.
The obtained data were used to estimate the average power of the plasma effect by multiplying the current array by the voltage array and the amount of supplied energy by integrating the power over time.
According to the obtained data, it is possible to indirectly estimate the energy efficiency of the synthesis process: with an increase in the mass of the initial mixture from 0.5 g to 2 g, the specific amount of energy relative to the initial mass decreases from 520 kJ / g to 130 kJ / g.
According to X-ray diffraction data, the samples have a crystal structure: there are two phases of molybdenum carbide - Mo2C and Mo1.2C0.8, and an ultradispersed graphite phase is also present in the samples.

Simultaneously to those chemical changes, a gradual reduction of oxide phases by presence of Se should occur to a point where the mayor reaction product would be the PbSe phase.
It is acknowledged that high energy ball impact results in particle size reduction, down to nanometric sizes.
In the upper curve, dots correspond to the experimental data, and the continuous line corresponds to the calculated diffraction pattern.
The lower curve represents the difference between the experimental and calculated data.
