A see-through pipe protruding from the gallery wall is filled with dust and dirt: it's like a hypodermic needle extracting vital organic samples of the building's physical construction.
The experiment exposed organic samples of astronomical interest for a duration of 97 weeks (∼22 months) to the space environment.
The latest addition to the already solid Leaf roster is 26-year-old Parisian Cécile Schott, who effortlessly blends organic samples of traditional Asian music (koto and tuned percussion) with organ, live drums, and looped vinyl samples to create a sweetly innocent atmospheric album.
The ion beam physics group at the ETH, Zurich, has designed an Automated Graphitization Equipment (AGE III) for routine graphite production for AMS analysis from organic samples of approximately 1 mg.
C/N ratios for PP and LP organic layer samples were estimated using the C/N ratio for the corresponding mineral samples and the relationship between values of mineral and organic samples of the other ecozones, with estimated values shown as a range (upper portion of bars).
Since isotopic ratios of H, C, and N are sensitive indicators for determining extraterrestrial organics, we have measured these isotopes of Hayabusa category 3 organic samples of RB-QD04-0047-02, RandD02-0120, and RB-QD04-0001 wion imagingging using a NanoSIMS ion microprobe.
In total, there were collected 238 (144 conventional and 94 organic) samples of quarters with clinical mastitis from 177 cows (107 conventional and 70 organic).
For each sample, 64 scans were recorded with a 4-cm−1 resolution over a 4,000 to 400 cm−1 range on pellets obtained by pressing a mixture of 1 mg organic sample and 400 mg dried KBr.
On average there were 0.75 detections of residue per organic sample (379 total detections among 502 samples).
Among cooked samples, roxarsone was detected in 19 of the 40 conventional samples and in 20 of 34 samples from producers without policies prohibiting use of arsenical drugs, compared with none of the 25 organic samples and only 1 of the 13 conventional antibiotic-free samples (from a producer with a stated arsenic-prohibiting policy).
In its PDP program, the USDA does pick up some organic samples (4.8% of the total in 2016).
