Erbium (Er) is # 68 on the Periodic Table of Elements. Elemental erbium is a silvery-gray metal. It is one of the "rare earth elements" (REEs) and occurs in few minerals.
Thirty-nine isotopes of erbium are known - six occur naturally. The most common variety is erbium-166. Erbium-162, erbium-164, erbium-167, erbium-168, and erbium-170 occur in lesser to very small amounts.

element of interest added to one of the stages was that the transition from the rifle engagement area to where you drew your pistol to engage four steel.
you could either ground your rifle in a barrel at the left end of the rifle shooting area, draw the "fighting Knife" (aka dismounted enfield Spike bayonet) attached to the side of the barrel, charge/stab the above target, drop "knife" engage steel with pistol.
Or you could do as I have done here, start the stage with a mounted bayonet shoot all rifle targets, charge/engage the bayonet target, ground rifle across the barrels to the right and engage pistol steel.
This is my bearded dragon G. This represents You by him meaning so much to me he's a part of me. I took this at home. I fixed levels and brightness/contrast. Depth of field shallow. Key element color. Key principal texture. Light coming from lamp.
Zirconium (Zr) is # 40 on the Periodic Table of Elements. Elemental zirconium is a silvery-gray metal. The most significant Zr-bearing mineral is zircon (ZrSiO4, zirconium silicate). Zircon is important in geology for its chronometric value - it is used for dating rocks. Iron (Fe), thorium (Th), and uranium (U) can substitute for the Zr position in zircons. Th and U are radioactive, so parent-daughter isotope ratios can indicate the age of particular zircon crystals.
Thirty-eight isotopes of zirconium are known - six occur naturally. Zirconium-90 is the most common variety. Zirconium-91, zirconium-92, zirconium-94, and zirconium-96 occur in minor amounts. Zirconium-93 is radioactive and occurs in trace amounts only.

Elementos de señalización urbana y vial para regular y hacer mas ordenada la circulación en ciudades y vías circulatorias . Isletas delimitadoras de vados y contenedores. Con las isletas de hormigón para vados se facilitan los accesos a garajes o pasos de vehículos y zonas de parking en general. Las isletas delimitadoras mejoran la maniobrabilidad en dichos accesos.
También utilizadas para delimitar contenedores de recogida de residuos urbanos.

I love the contrast in this picture between the sky and the ground and cow, I also really like the colors in this picture. I dont like how the picture isnt really crisp or clear
