Happy Thanksgiving, and safe and pleasant travels to and from visiting with family, friends, colleagues and associates.

As Greg has mentioned in the past, caring and sharing with the community, as well as the intellectual stimulation, and learning (continuous education). I believe that the members of the community are likewise curious, are interested in learning and are committed to sharing accurate information.

I caught the tail end of a video about a new application for treating chemical or process waste, which is applied to 'red' mud or contaminated bauxite residue, but the person of interest mention recovering critical minerals from consumer electronics, as well as treating mine tailings and...

Considering the definition of kerma (kinetic energy released in matter) = "the sum of the initial kinetic energies of all the charged ionising particles liberated by uncharged ionising particles in a volume element of mass dm." Other definitions replace 'uncharged' with 'indirectly', but it...

According to the Smithsonian site, Some other Youtube videos have shown lava founatins, but I don't know if that is for show, or it is actually one of the fissure vents on Hayli Gubbi.

Ref: https://recherche-expertise.asnr.fr/sites/default/files/documents/professionnels_sante/documentation/syllabus_chapitre_2.pdf The nuclear recoil T2 counts to the kerma. The kinetic energy of the incident neutron is transferred to the nucleus and proton. Now part of T1 is impart to the...

"The Hayli Gubbi volcano, located in Ethiopia's Afar region about 500 miles northeast of Addis Ababa near the Eritrean border, erupted on Sunday for several hours." The "volcano in Ethiopia's northeastern region erupted for the first time in nearly 12,000 years, sending thick plumes of smoke up...

Alpha particles can be created by ionizing and accelerating helium atoms, but requires significant energy. Otherwise, one needs a radionuclide source that decays by alpha emission, or a nuclide that undergoes an (n,α), which requires a neutron source. One refers to 10B(n,α)7Li, so as the 10B...

Ah, that's an important detail, and it's not so simple. For example, an (n,p) reaction might be preferred; one has to compare the threshold (neutron) energy and cross-section for the (n,p) and (n,α) reactions. So, what is the functional output of the system? Neutrons? Thermal energy? Well...

The point is to learn and not repeat.

I have visited Lampson's yard in Pasco, WA. They have a very large crane! In the article, Negligence! Preventable!

Hoover - Pilot Debrief Hoover Investigates AI Exploiting the UPS 2976 Tragedy! Hoover is a former fight pilot (USAF) and current pilot. I've watch many of his analyses (pilot debriefs), especially the small private and commercial aviation mishaps. He has an excellent presentation...

It is not clear why one would do that. Every radionuclide has a characteristic spectrum of alpha particles, which depend on internal nuclear states. In addition, for mass of a radionuclide, say in a spherical form, alphas will emit out of the sphere or into the sphere. Internally, the alphas...

It probably has been done, e.g., Space Shuttle Main Engine. One would have to query the team at NASA Stennis Space Center. I believe the SSME power head was disassembled and rebuilt after each flight for inspection, but it's been years since I looked into those details. A Defining Era: NASA...
