Lattice parameters obtained by Rietveld refinement of the XRD-data at room temperature for LaCo1-xNixO3 (x=0 and 0.05).
With increasing temperature, the spin state transition and the ratio of Co3+ to Co4+ would be changed, causing the reduction of the Seebeck coefficient [26].

Data analysis.The removal rate calculate by the following formula: η = ( 1- Cinfluent / Ceffluent ) x 100 %, where Cinfluent is the COD or mineral oil concentration in the influent and Ceffluent is the COD or mineral oil concentration in effluent.
COD average reduction efficiency are 67.9% and 88.4% after floatation and biological treatment respectively, and COD contents of the effluent are less than 100 mgL-1, the mean remaining COD contents is 75.52 mgL-1.
(a) 63×carrier without microorganisms, (b) 2000×carrier without microorganisms, (c) 2000×carrier with microorganisms in ASP reactor at the 127th day, (d) 2000×carrier with microorganisms in I-BF1 at the 127th day Conclusions The test system can remove almost BOD5, SS contents, pH reduce after floatation treatment and increase after biological treatment, COD average reduction efficiency are 67.9% and 88.4% after floatation and biological treatment respectively, and COD contents of the effluent are less than 100 mgL-1, the mean remaining COD contents is 75.52 mgL-1 can meet national discharge standards but exceed Liaoning discharge standard, so any technologies should be done to reduce COD content.

The animal models were chosen in accordance with the guidelines of 3Rs Program (Reduction, Refinement, Replacement), that aims to reduce the number of animals during experimentation and minimize pain and discomfort.
The presence of CO3, by partial substitution of PO4 e OH, provides the reduction of crystallinity and increased of solubility [11], consequently the cHA becomes more bioabsorbable than synthetic HA [19].
In our data, the ZnCHA kept the shape of microspheres during all experimental periods, presenting lower biosorption compared with cHA that showed a fragmented and almost completely absorbed biomaterial after 9 weeks.

Further reduction of the crystalline defects is inevitable to establish high volume production of SiC power switching devices.
Then, Al atom concentration at the depletion front for CV measurement is 2.3x10 18 cm -3 from the SIMS data, which should be the background of acceptor activation.
As a rough estimation, certain charged or neutral carrier trap centers may dominates the hole scattering, and ionized acceptors may take place for hole scattering under the reduction of carrier traps and hole generation from deep Al acceptor at high temperature.

Introduction The limitation of the global temperature increase to 1.5 °C since the beginning of the industrial revolution as a main goal from the climate conference in Paris 2015 [1], will require a significant reduction of CO2 emission.
Distance between counter surface and pin holder, friction force on the pins, temperature of the counter surfaces, and H2 gas temperature in the test chamber are continuously recorded and used as input data for calculations.
CTE [ppm/K] Axial Radial PPS/CF10f 87,4 73,5 PPS/CF20f 61,9 46,7 PPS/CF30f 58,3 30,1 content shows a significant effect in reduction of CTE exhibiting an increasing difference in axial and radial orientation, regarding pressing direction. 17 % difference for 10 wt.% fibers, 28 % difference for 20 wt.% fibers, going up to 64 % difference for 30 wt.% fibers, are subject for consideration.

At each positions, S21 phase is measured by the VNA, and this data is used to calculate phase velocity.
The tradeoff for the improved performance provided by this EBG structure is the small addition or reduction of an extra metallized area at the CSR edge.
If wideband surface wave reduction from hundreds of MHz to a few GHz needs to be achieved, combination of different CSR sizes is the best solution.

The reduction of PCB grain size results in an increase of the reaction surface between liquid and solid phase, which has a positive influence on the extraction of metals into the solution [7].
The presence of oxygen in the solution causes tin to react in preference which corresponds with measured data.
It was confirmed that particle size reduction results in increased metal extraction, which is caused by increasing reaction surface.

The limit of reduction in thickness for the cold rolling of a Mg-8% Li alloy exceeds 80% [11].
For the other ingots, the ends were removed to give lengths of 100 mm and average diameters of 50 mm and they were then extruded at 373, 473 or 573 K at rates of 1, 5 and 10 mm/s to give rods with diameters of 10 mm corresponding to a reduction ratio of 25:1.
Similar data are shown in Fig. 4 for the width distributions of α and β phases with the extrusion temperature in the cast+extrude+ECAP condition.
