Ordnance crest "WHAT'S IN A NAME" - military education about SNL. This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958.
The BOD value is most commonly expressed in milligrams of oxygen consumed per liter of sample during 5 days of incubation at 20 °C and is often used as a surrogate of the degree of organic water pollution. [1] Biochemical Oxygen Demand (BOD) reduction is used as a gauge of the effectiveness of wastewater treatment plants. BOD of wastewater ...
BOD Bottle BOD test bottles at the laboratory of a wastewater treatment plant. BOD Bottle or an incubation bottle is a main apparatus used for the Biological Oxygen Demand (BOD) test. During the five-day BOD or BOD5 test process, the BOD bottle is used for incubating diluted samples under the 20 °C or 68 °F of temperature.
Single element systems, and more recently pixelated imaging detectors such as the high energy X-ray imaging technology (HEXITEC) system, are capable of achieving energy resolutions of the order of 1% at 100 keV. In recent years, a different type of EDS detector, based upon a superconducting microcalorimeter, has also become commercially ...
In 2019, the isomer's excitation energy was constrained to 8.28 ± 0.17 eV based on the direct detection of internal conversion electrons [46] and a secure population of 229m Th from the nuclear ground state was achieved by excitation of the 29 keV nuclear excited state via synchrotron radiation.

The online public access catalog (OPAC), now frequently synonymous with library catalog, is an online database of materials held by a library or group of libraries.
The Army plans to introduce the torso and extremity protection (TEP) system beginning in 2018, which includes a modular scalable vest, ballistic combat shirt, blast pelvic protection system, and battle belt to reduce overall weight from 26 to 21 lb (11.8 to 9.5 kg) while maintaining coverage by reducing excess bulk.
