For many states, it is a key figure of market economy.
And still, exactly money, material independence are the catalysts of the innovative ideas; they allow to develop the capabilities and to bring notable benefit to society.
It is even worse if they impart the negative attitude towards material welfare as to something shameful and even dangerous.

Study on Energy Conservation Experiment for Heat Pipe Air-Conditioning System Shimei Sun, Jingmin Zhou Jilin Institute of Architecture and Civil Engineering, Changchun, 130118, China.
The materials of shell and fin are copper and aluminum respectively, and the working medium inside the tube is water.
Hence, to choose an optimum fresh air ratio is key in our research.
Heat Pipe Technology and Its Application on Engineering.

Materials used in external breast prostheses.
Regarding the materials used in conventional external breast prostheses, silicone, cotton, and synthetic foams are among the most commonly identified
Although these materials serve basic functional purposes, they exhibit multiple limitations, including excessive weight, poor breathability, high cost, limited durability, and inadequate anatomical adaptation.
In response to the limitations of conventional materials, new alternatives have been explored for the fabrication of personalized external breast prostheses.
