The measured values by EDX were in excellent agreement with the thermodynamic calculations obtained by Thermo-Calc (database: TCFE6) and also data on Mn-enrichment found in recent studies concerning Medium-Mn steel development [14].
TIA between 620 °C and 640 °C resulted in the desired properties with Rm*Atotal ~ 30.000 MPa% while higher TIA led to a strong reduction in total elongation accompanied by a strong gain in tensile strength

Since then, sustainability in construction has evolved to encompass various aspects, including energy efficiency, water conservation, waste reduction, use of environmentally friendly materials, and consideration of social and cultural impacts [1]-[3].
In the thesis [16] was calculated, based on the data provided by the company producing CETRIS boards in Hranice na Moravě, that theoretically during the constant production and subsequent processing of CETRIS cement chipboards, approximately 7 600 tons of waste is produced per year.

In the article [10], the corroded rebar specimens were obtained in the same way and the influences of the rust pits on mechanical properties of steel are studied and found the obvious stress concentration phenomenon comes into being near the rust pits, causing local steel yield in advance, and this is the mainly reason for the reduction of yield strength and elongation of corroded rebar.
For example, by using the fatigue calculation functions of ANSYS to analyze the existing experimental data from the perspective of fatigue life[26], it was found that the location, quantity and distribution of rust pits have effect on the fatigue life of corroded steel bar.

No drug crystal was found when higher polymer ratios were employed (Fig. 1e and 1f), even though the spray-dried DS crystals were large (data not shown).
Differently, the intensity reductions of DS main peaks and -OH stretching bands of HPMC F4M in the spectra of microparticles were found without new absorption peak or shifting in every drug:polymer ratios.

The data of yield and nitrogen uptake of maize in 6 years experiment (Fig.1 right) can be obtained from Gao et al. (2009) and Cai et al. (2012) in our project team.
The five treatments followed the local farmer traditional planting methods, planting density, sowing, and the harvest data, as well as fertilizer application period.
In China, Urea as a traditional nitrogen fertilizer was used widely, at the same time controlled release fertilizers as new style fertilizer were accepted by farmers, whose advantage of yield stability, N rate reduction and single basal application were evident in recent years.
According to the analysis of continuous 6 years data in high fertility soil, there was remarkable difference on nitrate accumulation between single basal fertilization and top-dressing fertilization (Fig.5), nitrate accumulation of single fertilization was less due to lower N fertilizer rate.

The electrical conductivity of the composites generally increases with increasing filler content, higher filler loading levels, however, can be accompanied by a reduction in mechanical properties if the filler particles are insufficiently wetted [1].
Frequency dependence of absorption coefficient (a) and refractive index (b) of (□) pure HDPE, (Δ) 2.22% MWNT, (○) 9.03% C60 and (◊) 2.52% CB; solid lines are fitting data.

Reduction in structural defects by laser recrystallization of initial poly-Si makes possible to increase substantially the carrier mobility in a layer.
The Keithley 2000 and Keithley 2010 digital voltmeters with the simultaneous automatic registration via the parallel port of PC, the vizualization and saving the data arrays into files have been used to measure the voltage at the potential contacts of samples, the output of thermocouple and the magnetic field sensor with the accuracy of upto 1´10-6 V.

The parameters of rolling process is: heating temperature 1200°C, holding time 3hours, and the reduction schedule is 30→22→14→9→6→3.5 (mm), after rolling,water cooling,then covered with asbestos felt so that it can be cooled slowly and simulated coiling.
The performance data according to table 2, the yield strength, tensile strength of E11 and E12 close to each other, but BH value and BHT values differ considerably, which due to the differences between microstructure.

The key of urban agriculture is to combine the production area with consumption area, reducing food miles and energy consumption during food supply, so as to achieve CO2 emission reduction targets.
Seeing the dilemma of the development of mordern cities, urban agriculture is worthy to have a try anyway, although we don’t have sufficient data to confirm its overall effectiveness.
