Exploration of the origin of uranium ingots from Nazi Germany

Before it came to Nazi Germany, the Allies disrupted this plan and seized uranium missiles that were at the heart of the plan. The fate of most of these ingots is unknown, but some have reached the United States and European countries . American chemists have developed a method for identifying the mine from which uranium came

U.S. and British military forces captured some of Heisenberg’s uranium ingots in 1945, and more than six hundred ingots were sent to the United States. Some may have been used as part of the U.S. Nuclear Weapons Program – which was also launched in part for fear that Nazi Germany is making progress in its military nuclear program – and some have reached various research institutes and institutions. The PNNL Research Institute utilizes the samples in its possession to train the border guard forces as well as researchers in the field of nuclear forgery, in identifying nuclear material. It is believed that the source of these ingots is in Heisenberg’s laboratory, but this hypothesis is not verified. “We did not have any practical measurements to support this supposition,” says the researcher.

In order to determine the exact origin of the ingots, the researchers used an analytical method called radiochronometry, the nuclear version of a method used by geologists to determine the age of the samples in their possession. Based on the concentration of radioactive isotopes. When the ingots were made, they contained mostly pure uranium metal. As time went on, radioactive decay converted some of the uranium atoms into thorium atoms and protectinum atoms. The researchers adapted the analytical method used by geologists to separate and quantify more accurately the chemical elements in the ingots. The relative concentrations of the individual elements within the ingot will indicate the age of the entire ingot. In addition, researchers will be able to use this method to measure infections of other elements.

The researchers will be able to uncover the mine where the uranium was quarried, a finding that could point to the specific Nazi laboratory that was the source of the uranium. In addition, the researchers are testing the coating layer of the ingots designed to reduce the oxidation of the ingot. Researchers recently found that a uranium ingot at the University of Maryland is coated with a layer of styrene – an unexpected finding since the Heisenberg research group used a cyanide-based coating rather than styrene. At the same time, the research team found that some of the ingots from Divner’s group were sent to Heisenberg’s laboratory. “We are curious to know if this specific ingot is one of the ingots used by the two laboratories in Nazi Germany,” says the lead researcher.

    ANA、737-500「スーパードルフィン」グッズ販売

     全日本空輸(ANA/NH)は、2020年6月に退役したボーイング737-500型機「スーパードルフィン」をモチーフにしたトートバッグなどのグッズを、通販サイト「ANAショッピング A-style」で販売している。従来機内販売で扱っていた商品で、新型コロナウイルス感染症(COVID-19)の影響で飛行機に乗る機会が減少する中、通販でも購入できるようにした。 ぬいぐるみショッピングバッグ(左)とステーショナリーセット(A-styleから) ANAの737-500=PHOTO: Tadayuki YOSHIKAWA/Aviation Wire  販売しているスーパードルフィンのグッズは、ぬいぐるみショッピングバッグとステーショナリーセットで、いずれも税込3000円。準備数がなくなり次第販売終了になるという。  737-500は1995年7月21日に1路線目の福岡-鹿児島線に就航し、離島を含む地方路線に25機が投入された。「スーパードルフィン」の愛称は、当時のエアーニッポン(ANK/EL、現ANA)が社内公募を行い、機体がイルカに似ていることや、小回りが利いてスピード感があること、元気で親しみやすいことなどの理由で名付けられた。  座席数は1クラス126席で、ANAグループが運航する737の中でもっとも小さい機体だった。カウルにドルフィンが大きく描かれたエンジンは、CFMインターナショナル製CFM56-3を採用。従来よりも大型化したため、正面から見ると空気を取り入れる「インテーク」下部が平たく見える「おにぎり型」なのが特徴だった。  全機が退役したが、整備訓練機として1機(JA301K)が羽田に残っており、3月には撮影ツアーが開催される。 関連リンクANA STORE@SKY SELECTION(A-style)全日本空輸 ・ANA、整備訓練機の撮影ツアー 737-500退役機、3月に羽田格納庫(22年2月2日) 写真特集・ANA 737-500スーパードルフィン退役 福岡編 四半世紀で500人以上が操縦桿握る 羽田編 737クラシック日系最後の商業運航 写真特集・ANA 737-500スーパードルフィン福岡公開 機内編 アナログ計器やシート灰皿跡が四半世紀物語る 外観編 イルカ描かれたエンジンカウル ANAの737-500関連 ・ANAの737-500スーパードルフィン最終便、福岡から羽田到着 25年間運航(20年6月14日) ・ANA、737-500に退役記念デカール スーパードルフィン3機に(19年12月7日) ・ANA、福岡で737-500感謝祭 20年春退役前に家族連れでにぎわう(19年9月29日) ・なぜA220は中部でデモフライトを実施したのか 特集・日本の100-150席市場を考える(19年8月14日) ・ANA、バッテリーで動く牽引車の実証実験 リモコン操作で737移動(18年10月15日) ・ANA、福岡-宮古を20年ぶり再開 季節便でスタート、通年化視野に(18年6月1日) ・ANA、退役機を整備訓練機材に 737-500転用(18年5月11日) ・エア・ドゥ、特別塗装機ドリーム号が退役 63万人運ぶ(14年11月30日)

    Reprogrammed fat cells support tumor growth

    Mutations of the tumor suppressor p53 not only have a growth-promoting effect on the cancer cells themselves, but also influence the cells in the tumor's microenvironment. Scientists at the German Cancer Research Center (DKFZ) and the Weizmann Institute in Israel have now shown that p53-mutated mouse breast cancer cells reprogram fat cells. The manipulated fat

    Cell types of origin of the cell-free transcriptome

    AbstractCell-free RNA from liquid biopsies can be analyzed to determine disease tissue of origin. We extend this concept to identify cell types of origin using the Tabula Sapiens transcriptomic cell atlas as well as individual tissue transcriptomic cell atlases in combination with the Human Protein Atlas RNA consensus dataset. We define cell type signature scores,…
