Abstract.The use of nanoparticles with carbon dioxide foams has been proposed for enhanced oil recovery due to their robust chemical stability in harsh environment.
Limestone showed the higher porosity reduction at the end of experiment compared to sandstone with the porosity of 7.56% on limestone and 12.49% on sandstone respectively.
The initial porous medium condition was set up all over again to ensure that a significant oil recovery data could be collected at the end of the experiment.
The residual oil contacted with CO2 foam slugs was not properly solubilized into the micro emulsion with less capillary pressure reduction between grains and oil cannot be removed from the sandpack.

In summer, gaseous fuel reduction by 10% could be achieved and the detail results are presented in this paper.
Fig. 6: Operation data of cooling (20th May) Fig. 7: Operation data of cooling (28th July) Evaluation Status and Results Operation conditions.
Figure 6 shows the operation data on May 20 and Figure 7 shows the operation data on June 28.
From the data, it was confirmed that the solar heat priority usage function and gas-based backup function operate properly and overall system functions normally.
Cooling operation starts in late May, therefore, the monthly reduction rate shows the data only in June, however, reduction by 10% could be achieved and the results as estimated were obtained.

The data were collected through three scans: first heating, cooling, second heating.
This data confirms that volume fraction of PLLA/TCP 70/30 amounts for 48/52 by weight.
The data are similar to those presented for PLLA/HA composite [20].
After compression moulding, it drops from 214.1 to 209,9 and from 0.249 to 0.235 dm3 g1 for PLLA and PLLA/TCP, respectively.Based on those data we can conclude that thermal processing of the PLLA causes its degradation resulted in viscosity reduction.
On the other hand, 12 months of incubation caused only slight reduction in molecular weight of the polymer in PLLA/TCP samples.

The much reduced field at the Schottky interface allows an increase in the drift doping concentration, which enables a significant chip size reduction on next generation SiC (Silicon Carbide) Schottky diodes.
The micro-pipe density on SiC has been routinely reduced to <1 cm2, along with a continuous reduction in threading dislocations.
The experimental data have proven out that the trench JBS design reduces the reverse leakage current significantly.
The reduction of the Schottky interface field in turn allows utilizing a highly doped drift layer to shrink the die size, or implementing a Schottky material with lower barrier height for lower Schottky turn-on voltage.
Significant chip size reduction on next generation SiC Schottky diodes has been achieved by utilizing the newly developed trench structure.

As the building sector accounts for about 30% of Taiwan’s carbon footprint, improving the Green Building Literacy (GBL) of building owners or users through general education is important to the carbon reduction commitment.
According to the suggestions by the Delphi panel and guidance of GBL model which was constructed from paper review and countrywide survey data by using structural equation modeling, the GBL curriculum not only conveys the knowledge of fact but more emphasizes on the knowledge for action and basic design skill through the involvement in the specific activities, which are also used to improve students’ attitudes and responsibility to promote their behavioral performance.
Green building is an efficient way to solve the environmental problem that we face today, so that improving building owners’ or users’ literacy about green building is important to the carbon reduction commitment.
Data were collected by means of GBL questionnaire (including Cognitive, Affective, & Behavioral subscale) [4], teacher observation & reflective diaries, students’ assignments, student journal & report writings, and open-ended question test.

M. showed that heat treatment modified the chemical composition of the wood, resulting in reduction of water absorption by the cell walls due to the reduction of hydroxyl groups [5].
As a result of processing of experimental data the dependence of the equilibrium moisture content of wood by temperature treatment was obtained (Fig. 2.).
Based on these data it is concluded that the increase of temperature of wood treatment leads to the release of the cavities of the vessels, causing them to become hollow.
As a result of the investigations of thermally modified oak wood the data about the content of extractives soluble in water and depending on temperature processing of timber were obtained (Fig. 6).
In addition there is a significant reduction in equilibrium moisture content of wood with increasing temperature of treatment.

The reduction of water through use of dilute chemistries [3,4] and recycling of wafer rinse water [5,6] has previously been reported.
Since wet cleaning accounts for a significant percentage of all processes, reduction of UPW and SPM presents an opportunity for engineered solutions to improve the efficiency of UPW and chemical use.
Figure 2: 80°C Temperature stability performance data.
Resist strip and >26-nm particle performance of the reclaimed SPM was demonstrated to be equivalent to single-pass SPM, and 70% reduction of SPM volume has been realized at customer sites worldwide [9,12].

PCM’s incorporated into concrete pavements have shown significant temperature reduction effects, mitigating thermal stresses.
The reduction of urban heat island effects and energy demand ties into SDG 13, while improved energy efficiency supports SDG 7.
This data serves as the foundation for further calculations of temperature stresses within the scope of this current investigation.
Figure 5 reveals significant reductions in curling stress with increasing percentages of PCM.
Meanwhile, the P12 demonstrated significant thermal stress reduction but lacked balanced mechanical strengths compared to the P8 mix.

Original PTS algorithm
The main idea of PTS algorithm is dividing the input data into blocks, optimizing coefficient of each block, and last combining these blocks.
The principle diagram of PTS method First, define data symbol with vector X(X1,X2,…XN-1),then divide X into non-overlapped blocks, the number of blocks is V and the length of each block is N/V.
The position don’t inherit original data is zero.
The sending data on the first antenna call PTS algorithm to obtain coefficient vector A which have the best performance of PAPR.
So we could use vector B changing the data on the second antenna directly without the process of IFFT transformation and the process of searching for the coefficient vector.
