The IF steel was deformed at 500 oC by 7-cycle ARB (a total thickness
reduction of 99.2 %, corresponding to an equivalent strain of 5.6), while the 2N-Al and 4N-Al were
deformed at room temperature by 6-cycle ARB (a total thickness reduction of 98.4 %, corresponding
to an equivalent strain of 4.8).
A large fraction (51.8 %) of high-angle boundaries (with misorientation angles > 15 o ) are present in the specimen, as determined from the TEM data.
It was expected that such a treatment should improve the ductility without a large reduction in strength.
Note that the data here for IF steel are for 6-cycle ARB samples.
As for IF steel and 2N-Al, a small post-annealing additional rolling reduction led to a decrease in strength and an increase in ductility for 4N-Al .

Therefore, the
precipitate chemistry is considered useful in providing information about the precipitation or
dissolution behavior during annealing in the ferrite region, to help in the interpretation of internal
friction data.
This explanation was supported by STEM data [5] which showed higher Ti/V ratios for precipitates in the annealed steels as compared to Ti/V ratios for those in the as-received hot rolled steels.
The reduction in Snoek peak height observed with extended annealing time (beyond 60 seconds) is believed likely to result from diffusion of solute carbon to lower energy sites like 1 hr.
That is, a reduction of Snoek peak height can occur when the rate of solute carbon segregation to lower energy sites is greater than the rate of carbide dissolution.
Mn and P additions to Nb ULC steel resulted in a reduction in the carbon Snoek peak height.

Antioxidant activity is measured by calculating the reduction in DPPH purple light intensity which is equivalent to the reduction in DPPH concentration.
Based on these data, it can be said that the antioxidant activity value of bamboo leaf extracts is also influenced by the origin of the bamboo tree used.
Research conducted by Mongkolsilp et al on five Thai medicinal plants revealed that the higher the total phenolic content, the higher the DPPH free radical reduction activity.
This data is following several research reports which reveal that some flavonoids have been found to have anti-inflammatory activity, antiplatelet, and antidiabetic.
Free radical reduction test results (DPPH) obtained IC50 of 45 μg / mL and this shows an IC50 value greater than vitamin C (9.54 μg / mL).

This effect becomes more pronounced with stronger magnetic fields, resulting in greater reductions in voltage.
This effect becomes more pronounced as the magnetic field intensity increases, leading to greater reductions in resistance.
Compared to results for 140 mT, the performance of 150 mT indicates mild reduction as the improvement becomes less pronounced at higher pressures.
All tests were performed at a controlled temperature of 25°C ± 1°C, and data collected during major geomagnetic fluctuations were discarded.
These uncertainty ranges were integrated into the graphical representations and data analysis, confirming that the observed trends and findings are both dependable and statistically sound.

After entering the “post-Kyoto" era, the European Union set a goal of saving 20% energy in 2020, especially the Obama administration proposed a clear target of emission reduction in the United States, China will be exposed to the increasing international pressure in emission reduction.
Take the data in 2006 as an example, the comparison of energy consumption of several typical nations as shown in Fig. 3, China's unit GDP energy consumption is 4 times of the United States’, 8 times of Japan’s, 3 times of the world average level.
China should accelerate the development of energy-saving and emission reduction technologies, and support key and exemplary energy saving projects, encourage the popularization and application of high efficient products.
CONCLUSIONS AND REMARKS Chinese government has set out a comprehensive objective to achieve 4 times GDP growth with only 2 times energy consumption and 10% emission reduction by 2020.

Furthermore, a study by Marchetti et al. [29] reported that a bucket handle tear (50 mm) led to a substantial rise in CP (121%) and a significant reduction in CA (53%).
For example, an experimental study found that 50% radial tear causes a greater reduction in the strain (4.67-2%) in the anterior portion and a marginal increase in strain in the posterior portion (2-2.5%), while 100% radial tear resulted in the total loss of functionality of the meniscus [28].
For example, an experimental study reported that 100% radial tear in the posterior horn of LM causes a 50% rise in CP and a 47% reduction in CA relative to that of the intact knee joint [43].

In the area of the reception of goods, the article deals with the utilization of the Electronic Data Interchange for the Despatch Advice (EDI DESADV) in combination with the exploitation of the Serial Shipping Container Code (SSCC) during the goods reception.
Manual receiving by “pencil-paper” and then the data having been put into the information system becomes of disuse because obviously the usage of modern technologies is indisputable.
SSCC codes can be used when receiving the goods out of the suppliers, who already are communicated by EDI (Electronic Data Interchange) messages.
There is an option to achieve even higher effectiveness in combination with electronic bill of delivery by EDI communication (Electronic Data Interchange).
Accuracy of elaborated data is of 99,9%.

In this paper the Capital Asset Pricing Model has been integrated with Penalized Spline Semiparametric Method in order to obtain an algorithm that allows to rationalize the appraisal of undivided real estate shares using easily accessible data.
These issues imposes the need to search a logical solution capable to rationalize the appraisal of undivided real estate shares, considering that these shares have more difficulty to selling and a reduction of their market value [2].
Data description and empirical analysis The described model in previous section was implemented on the basis of data relating to a time period from the second semester of 2002 to the second semester of 2013.

In particular, the amounts of mean percentage error (0,53%) and average standard error (0,68%) are acceptable because estimated values show a trend in line with observed data, also the residual analysis shows no anomalies.
