A physician or specifically educated technician, known as a sonographer, will carry out most transvaginal ultrasounds. A transvaginal ultrasound is an easy and painless procedure that requires very little preparation. Unlike X-rays, ultrasound scanning techniques do not use radiation, which means that they haven’t any harmful side effects and are very secure.

The right theoretical clarification of these relaxation phenomena was given in general form in 1937 by Soviet scientists L. Relaxation principle thus became the premise of molecular acoustics. A large variety of institutes and laboratories within the USSR and overseas are engaged within the study of ultrasound and its functions.

Ultrasound performs an extremely essential position in hydroacoustics, since elastic waves are the only waves that propagate nicely in seawater. The operation of, for instance, sonic depth finders and sonar relies on the reflection of ultrasonic pulses from obstacles mendacity of their path. It provides a robust means … Read More

One possibility is that they’re the result of mergers between star-size black holes. In 1970, Stephen Hawking and Roger Penrose confirmed that black holes must exist. Although the black holes are invisible (they cannot be seen), some of the matter that’s falling into them is very bright.

Today there is nearly universal agreement that black holes exist, although their precise nature remains to be in query. Some believe that the material that falls into black holes may reappear elsewhere in the universe, as within the case of a wormhole. The discovery of pulsars supported this principle and, shortly thereafter, physicist John Wheeler coined the term “black hole” for the phenomenon in a December 29, 1967 lecture. A black hole is commonly explained in terms of an object or mass “falling into” it.
