The possibilities of utilization of anisotropic optical thermoelements (AOT) with different magnitudes of optical transparency for the registration and transformation of high-intensive ray currents are observed. The solu...

The solutions of non-stationary equation of thermoconductivity for the optical non-transparent thermoelement at impulse ray excitement are presented in the paper for two time ranges: when the ray current falls (0<t&lt...

A new biomedical material to be used as part of acrylic bone cement formulations is described. This new material is tough, its Young's Modulus is similar to the one of poly (methylmethacrylate) and the contrast agent, us...
