The system consists of a bottom die tool for specimens positioning and an upper die tool containing an ultrasonic sonotrode, a holder, and a load cell, in addition to other digital components such as an ultrasonic generator, a signal amplifier and a data recorder.
Fig. 3 showed the stress reduction percentage during ultrasonic-assisted compression tests with varying height.
Stress reduction percentage during ultrasonic-assisted compression tests.
Previous study about ultrasonic-assisted forming explained the expansion of interfaces by friction reduction [9], however, only friction reduction could not clarify the mechanism of local anti-barreling shapes in every specimen.
The critical condition for occurrence of ultrasonic dynamic impact effect is confirmed to be 2λE/H > σ0.2, and ultrasonic impact is more effective on specimens with smaller dimensional height for stress reduction, even an average stress reduction of 87% can be achieved with smallest height of 1mm, showing the promising prospect in micro forming. 2.

Governments around the globe have been working hard to reduce carbon dioxide emissions effectively and meet the goals of energy conservation and carbon reduction [1-3].
The more products that are developed through recycling from microalgae, the more benefits of reasonable cost and high added value carbon reduction solutions can be achieved [4].
However, Taipower’s microalgal biotech skincare products have yet to be released to the market; hence, no actual marketing/consumer data is available for quantitative assessment.
In the analysis of social promotion benefits, four indicators for appraisal were used: “These products help promote skincare products developed based on carbon reduction”, “These products help raise interest to purchase products developed based on carbon reduction”, “These products help raise interest to produce products developed based on carbon reduction”, and “These products help governmental focus on products developed based on carbon reduction.”
Regarding other indicators, the indicator of “These products help promote skincare products developed based on carbon reduction” has an acceptance rate of 71.0%; the indicator of “These products help raise interest to purchase products developed based on carbon reduction” has an acceptance rate of 69.5%; and the indicator of “These products help raise interest to produce products developed based on carbon reduction” has an acceptance rate of 67.5%.

The current CPT-based liquefaction evaluation method, including Chinese code method, the Robertson method and the Olsen method, was verified by those 39 field test data.
The results show that the success verification ratio of Chinese code method, the Robertson method and the Olsen method are relative low by using Bachu earthquake data.
CPT has speed, data continuity, good reproducibility and effortless operation, etc., which is a convenient and reliable in situ test method.
Supplies the penetrating power using the domestic drilling vehicle, while the test is mainly produced by the Dutch a.p.v.d.berg Corporation’s drill pipe, the probe and data acquisition system transmission.
Liquefied level determination and decision results A very important step in survey data analysis is to determine the liquefied and non-liquefied layer position and thickness.

The flow coefficient that changed according to time was calculated, and the flow-coefficient data from the injector-needle movement were secured.
Study Method The internal structure of the Urea-SCR injector and the design data for the hydraulic circuit were secured, and the Urea-SCR injector that was actually used was reverse-engineered to conduct the study.
It is expected that this result will be the cause of the reduction of the effective-flow area.
An unsteady analysis by time was conducted, and the discharge coefficient of the changing injector was used to obtain the discharge-coefficient data using the motion of the injector needle.

One cm thickness sheets, cut from this cylindrical ingot, were cold rolled at different reduction amounts i.e. 50%, 70% and 90%.
The OIMTM software was used to analyze the EBSD data.
The recrystallized microstructure (grain size) is still heterogeneous after lower cold rolling reductions (50% and 70%).
Fig. 4a shows the stored energy evolution of components B, C and Goss in terms of the cold rolling reduction.
As mentioned above, the substructure is better formed in smaller grains when the cold rolling reduction increases.

This competition decreases concentration of the radicals like H, O and OH, leading to a significant reduction in laminar burning velocity.
The advantages in using DME are low combustion noise, low smoke and CO emissions, high thermal efficiency and certain degree of NOx reduction.
However, NOx emission of DME fueled engines still requires further reduction to meet stringent emission regulation.
This reduces concentration of the radicals like H, O and OH, leading to a significant reduction laminar burning velocity.

UV–vis absorption spectra of CTAB-stabilized gold colloids prepared by n-butanol situ reduction in W/O microemulsion under 30°C at the different molar ratios of CTAB/C18NH2.
These results show that monodispersibility of (CTAB+ C18NH2)-capped Au nanoparticles obtained through n-butanol reduction under 30°C is relatively high than the traditional methods [8, 9].
Conclusions We have successfully synthesized the (CTAB + C18NH2)-capped gold nanoparticles with a safe organic mixed solvent by n-butanol in situ reduction at room temperature (30°C).
In the slow reaction process of n-butanol situ reduction chloroauric acid, adding a small amount of alkyl amine, it can significantly weaken the guiding role of CTAB, which indicate that the dual effect of surfactant and emulsion droplet template can control the synthesis of the size and the morphology and the stability of the hydrophobic gold nanoparticles by the slow reduction system in the W/O microemulsion.
