A faster and less expensive form of radiotherapy, called Stereotactic body radiotherapy (SBRT), for treating prostate cancer may come with a higher rate of urinary complications.
The standard external beam radiation therapy for prostate cancer is currently intensity modulated radiation therapy (IMRT). Stereotactic body radiotherapy delivers a greater dose of radiation per treatment than IMRT so patients receiving SBRT can complete an entire course of treatment in one to two weeks,
The worldwide love affair with subsidized green energy is fading fast but that shouldn't be taken to mean the science is not solid.
In America, new power plants are difficult to get built and as a result the cost of electricity has gone up while the supply has gone down. Yet the government seems to still want to fast track alternative energy and regulations that allow small biomass plants may also help solve a grid problem that solar and wind energy only make worse.
Small biomass power
Until now, it has been well-established that coral complex in the Arabian/Persian Gulf only exist in the coastal regions of Bahrain, Iran, Kuwait, Oman, Qatar, Saudi Arabia, and United Arab Emirates and it was thought that there are no coral … Continue reading →
Following Emilio Elizalde (read this presentation in pdf) I found a paper by Stephen Hawking in which he used the Riemann's zeta function: This paper describes a technique for regularizing quadratic path integrals on a curved background spacetime. One forms a generalized zeta function from the eigenvalues of the differential operator that appears in the action integral. The zeta function is a meromorphic function and its gradient at the origin is defined to be the determinant of the operator.
Ever wonder what it’s like to work at a national laboratory? Well, Rene Delano can tell you. Check out the video below to get a peek into just one of the many fascinating jobs held by national lab researchers. Delano has worked as a machinist in the Lawrence Berkeley National Laboratory for the past 27 […]
