Jenny Morgan’s (featured in HF Vol. 21) paintings reveal beauty in simplicity. She often depicts nude figures with poignant expressions, stylizing their bodies to fit her sunrise-hued palette in lieu of focusing on minuscule details like hairs and wrinkles. The simplification of her subjects gives her work a glossed-over effect that pushes it from objective realism into surreal territory. For her latest exhibition “The Golden Hour” at Plus Gallery in Denver, Morgan explored notions of spirituality and the cycle of life. While her major focus has always been faces, often using herself as a subject, her exhibition features a substantial amount of paintings of skulls, alluding to the fading nature of youth and the ephemerality of the body. Take a look at the work in the show below and check out “The Golden Hour” on view through October 18. See more on Hi-Fructose.
Uranyl-nitrate-hexahydrate under UV light. Uranyl-nitrate is one of the most important salts of uranium, it is important for nuclear reprocessing, it is made by dissolving the spent nuclear fuel rods or yellowcake in nitric acid.
An interesting use for this highly water soluble uranium salt was a fuel for aqueous homogeneous reactors. In these reactors (water boilers) a soluble nuclear salt (usually uranyl sulfate or uranyl nitrate) was dissolved in water. The fuel is mixed with the coolant and the moderator, the water can be either heavy water or ordinary (light) water. The heavy water aqueous homogeneous reactor can achieve criticality (turn on) with natural uranium, so no enriched uranium is needed for this reactor.
Even since on the box everyone could read, that this compound is radioactive, how did I survive to take this photo? Uranium-238 has a really long half life (4468000000 years) and it only produces alpha radiation, what is stopped by a sheet of paper, or a few cm of air.
When working with “safe” low activity radioactive alpha emitting isotopes, the most important is to prevent the ingestion, since it is highly water soluble and causes severe renal insufficiency, acute tubular necrosis and is a lymphocyte mitogen. Target organs include the kidneys, liver, lungs and brain. What does this mean? You will die from it and it will hurt very-very much.
The liver provides critical functions, such as ridding the body of toxins. Its failure can be deadly, and there are few options for fixing it. But, scientists now report in the journal ACS Applied Materials & Interfaces a way to potentially inject stem cells from tonsils, a body part we don’t need, to repair damaged livers — all without surgery.
Byeongmoon Jeong and colleagues point out that currently, the only established method for treating liver failure or severe cases of liver disease is complete or partial transplantation. But the need is much greater than the number of available organs. Plus, surgery has inherent risks and a hefty price tag.
