Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The term helion is a portmanteau of helium and ion, and in practice refers specifically to the nucleus of the helium-3 isotope, consisting of two protons and one neutron. The nucleus of the other (and far more common) stable isotope of helium, helium-4, consisting of two protons and two neutrons, is called an alpha particle or an alpha for short.
A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.
Because they are identical to helium nuclei, they are also sometimes written as He 2+ or 4 2 He 2+ indicating a helium ion with a +2 charge (missing its two electrons). Once the ion gains electrons from its environment, the alpha particle becomes a normal (electrically neutral) helium atom 4 2 He. Alpha particles have a net spin of zero.
The helium hydride ion HeH + has been known since 1925. [70] The protonated dihelium ion He 2 H + can be formed when the dihelium cation reacts with dihydrogen: He + 2 + H 2 → He 2 H + + H. This is believed to be a linear molecule. [70] Larger protonated helium cluster ions exist He n H + with n from 3 to 14. He 6 H + and He 13 H + appear to ...

Featuring Lisa Kudrow and Ray Romano, Netflix's new dark comedy "No Good Deed" is "about the highs and lows of searching for a safe, happy home."
The last image we have of Patrick Cagey is of his first moments as a free man. He has just walked out of a 30-day drug treatment center in Georgetown, Kentucky, dressed in gym clothes and carrying a Nike duffel bag. The moment reminds his father of Patrick’s graduation from college, and he takes a picture of his son with his cell phone.
