cervisvenator: Hi

While I feel that Geocaching.com should hold the location for the cache owner and block other cachers from placing a cache in the area around this cache for a reasonable amount of time, we can’t do so forever.

Nothing seems to happen with this cache listing, so it is now archived, so that someone else can place a cache in the area, and geocachers can once again enjoy visiting this location. Also, if it hasn’t been done already, please pick up any remaining cache bits as soon as possible.

If the owner wants it reopened, send me an e-mail and I’ll be happy to unarchive the cache listing if it still satisfies the requirement/guidelines.

(This reviewer note is in English so non-Norwegian cache owners, geocachers and cache reviewers can understand what it says.)

Thanks for your understanding,
Cervis Venator

Geocache Description:

This is a cache in the IYC2011-series that is preparing for the
International Year of Chemistry in 2011. They will hopefully
increase chemistry knowledge as well as provide for good cache
experiences.

Each cache in the IYC2011-series contains a clue (on the log
sheet) to find the final IYC2011-cache to be released on
1/1/2011.

Iron

Iron is the chemical element with atomic number 26, represented by the symbol Fe.
Iron and iron alloys (steels) are by far the most common metals and the most common ferromagnetic materials in everyday use. Fresh iron surfaces are lustrous and silvery-grey in color, but oxidize in air to form a red or brown coating of ferric oxide or rust. Pure single crystals of iron are soft (softer than aluminium), and the addition of minute amounts of impurities, such as carbon, significantly strengthens them. Alloying iron with appropriate small amounts (up to a few per cent) of other metals and carbon produces steel, which can be 1,000 times harder than pure iron.

Pure iron is a metal but is rarely found in this form on the surface of the earth because it oxidizes readily in the presence of oxygen and moisture. In order to obtain metallic iron, oxygen must be removed from naturally occurring ores by chemical reduction – mainly of the iron ore hematite (Fe₂O₃) by carbon at high temperature. The properties of iron can be modified by alloying it with various other metals (and some non-metals, notably carbon and silicon) to form steels.

Iron is essential to nearly all known organisms. In cells, iron is generally stored in the centre of metalloproteins, because "free" iron (which binds non-specifically to many cellular components) can catalyse production of toxic free radicals. Iron deficiency can lead to iron deficiency anemia.
In animals, plants, and fungi, iron is often the metal ion incorporated into the heme complex. Heme is an essential component of cytochrome proteins, which mediate redox reactions, and of oxygen carrier proteins such as hemoglobin, myoglobin, and leghemoglobin. Inorganic iron also contributes to redox reactions in the iron-sulfur clusters of many enzymes, such as nitrogenase (involved in the synthesis of ammonia from nitrogen and hydrogen) and hydrogenase.

Non-heme iron proteins include the enzymes methane monooxygenase (oxidizes methane to methanol), ribonucleotide reductase (reduces ribose to deoxyribose; DNA biosynthesis), hemerythrins (oxygen transport and fixation in Marine invertebrates) and purple acid phosphatase (hydrolysis of phosphate esters).
