But it urged American citizens in Saudi Arabia to exercise caution and be aware when visiting commercial establishments and other areas frequented by Westerners. We have issued a warden message about our knowledge of ongoing operation planning for terrorist attacks in the kingdom and we have urged American citizens to maintain a high level of vigilance,  U.S. Embassy spokeswoman Carol Kalin told The Associated Press over the telephone.Neither the embassy nor the consulate planned to close, Kalin said.An embassy statement also referred to previous attacks in which  housing compounds and other establishments where Westerners may be located  were targeted.        Si stanley cup nce May 2003, Islamic militants have carried out numerous suicide bombings and kidnappings and have regularly battled security forces.The attacks, which have tended to target Westerners, have been blamed on the al Qaeda terror group and allied militants.      ponent--type-recirculation .item:nth-child 5          display: none;             inline-recirc-item--id-a1307902-8c88-11e2-b06b-024c619f5c3d,  right-rail-recirc-item--id-a1307902-8c88-11e2-b06b-024c619f5c3d         display: none;             inline-recirc- Teyk Minn. court intervenes when family refuses daughter s chemo
: m& a: r/ t' A You might be forgiven for thinking that what you ;re seeing here is a very well-constructed toy. But it   also a fully operational watt balance, the tool that   used to set the standard measurement of a kilogram.     Scientists at the National Insti stanley cup tute of Standards and Technology designed and built the fully-functional, though toy-based, watt balance, and then detailed their process in a working paper that they posted on ArXiv  it   also been submitted to the American Journal of Physics . The LEGO version of the watt balance is not the very best version of the equipment out there. The researchers note in the paper that there are some other existing watt balances out there in the world that have calibrated their relative uncertainty to within less than fraction of 1%. So why attempt to construct an equivalent LEGO version  For a couple reasons. For starters, even though the LEGO version is not the most accurate one, it   still a pretty darn good one, with a relative uncertainty of 1%. Also, though, the standards of measurement a stanley cup nd how they ;re derived are due to undergo a huge update i stanley mug n 2018. And, note the researchers, as a way of explaining the new concept behind how a kilogram is derived, the LEGO watt balance is pretty unbeatable: In the new SI, the kilogram will be defined via fixing the Planck constant, a way that is not apparent to most people. The LEGO watt balance makes it easy to demonstrates how electrical power relates to mechanica
