Lanthanides are metal ions which have their 4f energy level filled and generally refer to elements cerium to lutetium in the periodic table.  The fluorescence of lanthanide salts is weak because the energy absorption of the metallic ion is low; hence chelated complexes of lanthanides are most commonly used.  The term chelate derives from the Greek word for “claw,” and these are organic molecules which attach to the lanthanide metal ion through dative bonds.  If there is more than one organic compound (ligand) attached, then the term chelated complex is used.  The fluorescence is most intense when the metal ion has the oxidation state of 3+.  Not all lanthanide metals can be used and the most common are: Sm(III), Eu(III), Tb(III), and Dy(III). Zuffa, LLC ( ) is an American sports promotion company specializing in mixed martial arts.  It was founded in January 2001 in Las Vegas, Nevada, by Station Casinos executives Frank Fertitta III and Lorenzo Fertitta to be the parent entity of the Ultimate Fighting Championship (UFC) after they purchased it from the Semaphore Entertainment Group.  The word "Zuffa" is an Italian word (] ), meaning "fight".  On July 11, 2016, Zuffa announced that it would be purchased by WME-IMG for the price of $4 billion. This interesting surname is of German and Ashkenazic origins, used as an ethnic or regional name for someone from Franconia ("Franken" in Germany), which is a region of south-west Germany, so called because it formed an early Frankish settlement.  Thus Frankel is a German and Ashkenazic diminutive of this placename.  It may also be a form of "Frank", from the Norman given name "Franc", an ethnic name for a Frank (Germanic people who inhabited the Rhine region), plus the diminutive suffix "el", little.  Frank also comes from a medieval English and old French word "franc", meaning liberal, generous (it meant free in earlier times, because only those of Frenkish race were free).  German variant spellings include "Frankl, Frenkel, Frankel and Frankle", while Ashkenazic variants are "Frank(e)l" and "Frenk(i)el".  Elias Benjamin Frankel married Elizabeth Myers at Christchurch, Southwark, London on April 25th 1850.  One Marcus Frankel married Deliza Jones at St. John the Baptist, Shoreditch, London on December 4th 1871.  The first recorded spelling of the family name is shown to be that of Francois Franchel, (marriage to Anne Scott in London), which was dated December 4th 1799, London Church Registers, during the reign of King George III, "Farmer George", 1760 - 1820. Sturmgeschütz (or StuG) meaning "assault gun" was a series of armored vehicles used by both the German "Wehrmacht" and the "Waffen-SS" armored formations during the Second World War that primarily consisted of the StuG III and StuG IV.  The more common of the two, the StuG III, was built on the chassis of the proven Panzer III.  The StuG III was initially designated "StuG" but with the creation of the StuG IV it was re-designated the "StuG III" to distinguish the two.  Initially they were intended as mobile, armored gun platforms, providing close fire support to the infantry to destroy bunkers, pillboxes and other entrenched positions.  As the war progressed a number of aspects of the StuG series made them a valued supplement to the Panzer forces. Gerda III is a lighthouse tender located at Mystic Seaport in Mystic, Connecticut, United States.  "Gerda III" was built in 1928 in Denmark and was used as a common work boat.  In 1943 "Gerda III" was used to smuggle Jews from Nazi occupied Denmark to Sweden.  Approximately 300 Jews were rescued by "Greda III".  The Danish Parliament donated "Gerda III" to The Museum of Jewish Heritage in New York City.  Mystic Seaport now cares for the vessel and features her as part of their collection of watercraft.  The rescue story is the subject of the film, "A Day in October", released in 1991.
