Scientists from St. Petersburg Polytechnic University Peter the Great (SPbSPU), together with colleagues from Tsinghua University (China) developed a new method of diagnosing diseases based on the analysis of laser light scattering in blood serum. The results of the study were published in first quartile Biology publisher MDPI.
As explained in Spbpu, this method is fast, non-contact, safe, does not require the use of expensive reagents. These benefits, according to scientists, will allow it to be used in screening studies of blood, for example, in the framework of dispanserization.
Scientists from St. Petersburg Polytechnic University Peter the Great (Spbpu) found and theoretically explained a new physical effect, the essence of which consists in the possibility of growth of the amplitude of mechanical vibrations of an object without any external influence. In addition, they suggested that if the paradox of Fermi-Pasta-Ulam-Tsingou.
In SPbSPU is explained by a simple example: to rock the swing, they need to constantly push. It was believed that without continual external influence to achieve vibrational resonance is impossible.
