It's like giving life. Did you know that the victim of a serious crash can require blood from as many as 50 donors? Wow! That still floors me. A heart surgery patient can need blood from up to 5 donors! Why not get together with friends and donate as a group?10 May 2026 05:45 +0000at://did:plc:elceyk7ainuucm537tei4cjg/app.bsky.feed.post/3mli2lbenl22shttps://bsky.app/profile/heavy.bsky.social/post/3kcrea764hf25Of the radioactive minerals in the hand-specimen of uranium ore (see post of Jul 21, 2023), brannerite was the most abundant. Its crystallites form grain-aggregates with crystallites of rutile, exhibiting a variety of textures and compositions. Brannerite is an uranium titanate to which . . ./227 Oct 2023 22:52 +0000at://did:plc:elceyk7ainuucm537tei4cjg/app.bsky.feed.post/3kcrea764hf25https://bsky.app/profile/heavy.bsky.social/post/3k2zbs75xt62c🧪 Thus, autoradiography facilitates the mapping of radioactive minerals at or near the surface of a host rock sample.21 Jul 2023 07:08 +0000at://did:plc:elceyk7ainuucm537tei4cjg/app.bsky.feed.post/3k2zbs75xt62chttps://bsky.app/profile/heavy.bsky.social/post/3k2zbmh52fk2a🧪 Uraninite, uranothorite and monazite were the other abundant radioactive minerals. The intimate association of pyrite with the radionuclides, interstitial to the quartz pebbles, is noteworthy. Low-intensity radiation bands indicate the subsurface positions of some radionuclides. /...521 Jul 2023 07:05 +0000at://did:plc:elceyk7ainuucm537tei4cjg/app.bsky.feed.post/3k2zbmh52fk2ahttps://bsky.app/profile/heavy.bsky.social/post/3k2zawmbuet2h🧪 The image that follows is the autoradiograph of the hand-specimen. It was prepared by laying the flat face of the hand-specimen on a sheet of x-ray film for about 72 hours. The white spots and patches in the image were caused by radiation emitted from radioactive minerals, e.g., brannerite. /...421 Jul 2023 06:53 +0000at://did:plc:elceyk7ainuucm537tei4cjg/app.bsky.feed.post/3k2zawmbuet2hhttps://bsky.app/profile/heavy.bsky.social/post/3k2za2rddkq2n🧪 The abundant, reflective particles occupying positions around pebble boundaries and filling fractures within pebbles are pyrite; maximum size ~2 mm. /...321 Jul 2023 06:37 +0000at://did:plc:elceyk7ainuucm537tei4cjg/app.bsky.feed.post/3k2za2rddkq2nhttps://bsky.app/profile/heavy.bsky.social/post/3k2z7pxgs7a2n🧪 A sectioned hand-specimen of uranium ore is shown below. The rock type is quartz pebble conglomerate, with smoky and milky varieties of quartz pebbles in the size range of 0.5 to 4 cm. The median size is small, about 1.5 to 2 cm. The pebbles are tightly packed and well sorted. /...221 Jul 2023 06:31 +0000at://did:plc:elceyk7ainuucm537tei4cjg/app.bsky.feed.post/3k2z7pxgs7a2nhttps://bsky.app/profile/heavy.bsky.social/post/3k2r7ckl4sk2oAm I on the list so that I get a test tube emoji when I post a scientific piece?18 Jul 2023 02:03 +0000at://did:plc:elceyk7ainuucm537tei4cjg/app.bsky.feed.post/3k2r7ckl4sk2ohttps://bsky.app/profile/heavy.bsky.social/post/3k2qcmovft42tTo anybody on the Bluesky Team, here is a question. Why is Bluesky not listed in the apps notification list on my Android phone? Until I checked, I was wondering why I was not receiving notifications of messages/posts the way I do for WhatsApp, Twitter and everything else.17 Jul 2023 17:29 +0000at://did:plc:elceyk7ainuucm537tei4cjg/app.bsky.feed.post/3k2qcmovft42thttps://bsky.app/profile/heavy.bsky.social/post/3k2p4pxyrpv2vWhy don't I get notifications of Bluesky posts outside of Bluesky, as I do with every other platform?17 Jul 2023 06:11 +0000at://did:plc:elceyk7ainuucm537tei4cjg/app.bsky.feed.post/3k2p4pxyrpv2vhttps://bsky.app/profile/heavy.bsky.social/post/3jy3r5lz3fs2rThank you, @feloniousmonk.bsky.social .
