The emergency number on the label must be a domestic 24h emergency telephone number. The second mandatory national standard (GB 190-2009) -“Packaging Labels for Dangerous Goods" is based on the 15th revised edition of the UN recommendations on the Transport of Dangerous Goods. This standard spe...
The path to the base file must be absolute or relative to the location of the file to be extended. TheConfigurationclass By defaultget_config()andread_yaml_file()return aConfigurationinstance. For the most part aConfigurationobject is the same as a dictionary, and it can be used as such....
If any information in the MSDS changes, then related enterprises must submit the updated MSDS to MoEL as soon as possible. South Korea has adopted a 16-section MSDS, which aligns with the fourth revision of GHS. The MSDS and label must be authored in Korean. Unlike in China, t...
Must be one of: black, red, green, brown, blue, magenta, cyan, lightgrey, default, darkgrey, lightred, lightgreen, yellow, lightblue, lightmagenta, lightcyan, white, or '' (the empty string). file : writeable file-like object, optional Where to write to. Defaults to `sys.stdout`. ...
The calibration must correct only for the flux loss due to atmospheric throughput and the instrument response, but not for losses due to the finite geometry of the fiber aperture. This requires the use of standard star measurements to strictly separate these two flux loss factors (throughput ...
Besides the sheer volume of designs, there are strict time domain requirements ("cadences") that must be respected in order to complete the signature SDSS time domain surveys. This complex set of requirements necessitates software that can ensure cadence requirements are always respected, in ...
This sets a lower limit on theformation time-scales and star-burst components of early-type galaxies to ~0.4Gyr, which is the lifetime of a 3Msun star, since the full C enrichment must bereached. [N/Fe] correlates with velocity dispersion, but offset to lower valuesand with a steeper ...
We find that 8 of 17 quasars can be classified as dust-reddened. Three of these have upper-limits on the absorption column from X-ray spectral fits of N_H = 3-13 x 10^{22} cm^2, while the other five quasars must be absorbed by at least N_H = 10^{23} cm^2 in order to ...
Millisecond pulsars (MSPs) are being timed precisely in hopes of detecting gravitational waves (GWs). In order to detect GWs, pulsars must be studied in great detail. The perturbations in timing caused by binaries must be determined so as not to confuse them with a GW perturbation. This study...
