Application of deuteron-deuteron (D-D) fusion neutrons to 40Ar/39Ar geochronology.
Neutron irradiation of samples for 40Ar/39Ar dating in a 235U fission reactor requires error-producing corrections for the argon isotopes created from Ca, K, and, to a lesser extent, Cl. The fission spectrum includes neutrons with energies above 2-3 MeV, which are not optimal for the 39K(n,p)39Ar reaction. These higher-energy neutrons are responsible for the largest recoil displacements, which ...
متن کاملSports Science vs “Boutique Medicine”
T he practice of sports medicine in 2011 is fascinating. The advancement of disciplines like tissue engineering has expanded our armamentarium tremendously. Along with the typical orthopaedic toolbox of metal plates, rods, methylmethacrylate, and polyethylene comes synthetic membranes, biologic scaffolds, platelet-rich plasma (PRP), and stem cell treatments. To some extent, we can already biolo...
متن کاملExploring synthetic immunity: From boutique to global
With a father who was a research scientist and a mother who was a nurse, one would think a career in biomedical research may have been pre-ordained. However, growing up in the Apollo era, I had visions of NASA astronauts and astronomers on my mind. My early introduction to the research laboratory started in 1978 when I worked summers at the Wistar Institute while still in high school. It seemed...
متن کاملNeutrons for rafts, rafts for neutrons.
The determination of the structure of membrane rafts is a challenging issue in biology. The selection of membrane components both in the longitudinal and transverse directions plays a major role as it determines the creation of stable or tunable platforms that host interactions with components of the outer environment. We focus here on the possibility to apply neutron scattering to the study of...
متن کاملThe “higgs” from Anti-neutrons and Neutrons
The new anti-neutron, first proposed in 2011 [16], and ordinary neutrons, are both without electric charge, and are therefore rather difficult to accelerate and/or impact together in a high energy collider sufficient to cause annihilation, and thus create a 100% energy “Higgs” styled Boson, such Bosons arguably representing all of the mass in the universe. This very high energy impact combinati...
