Research has, for example, when taken it might actually lose energy. Therefore, it must find another way to make a minimal power consumption and can provide the maximum benefits.
For example, when the research was carried out can actually be achieved, but may have lost a lot of energy. Therefore, we must find other ways of making a low power consumption and can provide the most benefit.
Research on the practical examples, when used, can but may lose energy ไปมาก. Therefore, must find a way to other make consumption minimal energy and can make the maximum benefit.
