Hermann Vaske's Ad for Hornbach Silicate Paint
"Blixa Bargeld reads Hornbach" is an extraordinary yet relevant campaign for Hornbach superstore. In a series of 13 spots Bargeld, founder and singer of the cult band "Einstürzende Neubauten", reads the Hornbach catalogue, juxtaposing low art and high art in Ernst Jandl style. The winds of avant-garde blow through the Hornbach catalogue when Blixa Bargeld shouts "Bohrlochschwämme", and "Silikatfarbe" and "Quarzitpolygonalplatten". Blixa Bargeld, who is known for his collaboration with theatre legend Heiner Müller on "Hamletmaschine" as well as for his extraordinary stage acts with "Einstürzende Neubauten", delivers a breathtaking performance in his readings -- authentic, powerful, sensitive and ironic at the same time. "Blixa Bargeld turns the banal of the small print into a piece of art", says Paul Arden from ASD Lionheart. The films were conceptualized by Heimat Berlin and directed by Hermann Vaske, who also produced the spots. They were shot on Super 8 on location in Cannes, including an old aviation control station, an old harbour mole, a former hotel and an underground car park. "Blixa Bargeld reads Hornbach" is the discovery of beauty in unexpected places. Everyday culture is celebrated and day-to-day art business ridiculed. "Sometimes you can only see the truth when you turn things upside down", says Blixa Bargeld. "To read the Hornbach catalogue wasn't my idea, but I liked the idea and that is why I did it. If I hadn't treated texts in this way this before, I wouldn't have been able to see that it's possible." „I was fascinated by the project because it fulfilled my definition of creativity: to bring two things together that have nothing to do with each other, to form a third," says director Hermann Vaske who collaborated before with Bargeld on a commercial for the Erotic Art Museum in Hamburg. The films were shown on VIVA Music Television in conjunction with a Bargeld special. They will be shown on ARTE as part of a thematic evening about poetry.

JMDMT #2363 Microfossils of Cyanobacteria in Carbonaceous Meteorites
The James M. DuPont Meteorite Collection - minerals, kamacite (Ni ~5.3-6.3 wt%), taenite (Ni ~55-57%), and chromite are present. Besides troilite as a major sulfide, pentlandite, alabandite, and digenite were observed as accessory sulfides. In contrast to the case for silicates in (normal) IIE irons, where schreibersite is common, whitlockite was found in the Y 791093 silicate. All mineralogical and petrographic features suggest that the silicate portion of Y 791093 is an equilibrated H chondrite of petrologic type 5-6. Abundances of Mg-normalized refractory lithophiles and moderately volatile lithophiles in the Y 791093 silicate are chondritic, being similar to those for H chondrites. Both Br and Sb contents in the Y 791093 silicate are 3x and 2x higher that those in H chondrites respectively.

JMDMT #1123 Microfossils of Cyanobacteria in Carbonaceous Meteorites
The James M. DuPont Meteorite Collection - Recently new metal-silicate partition data for Ni, Co, Mo, and W were obtained allowing better estimates of the composition of the metal in the source region of eucrites. During the last years solubilities of Ni, Co, Mo, W, and Fe in silicate melts were experimentally determined at temperatures from 1300 degrees C to 1600 degrees C and at a wide range of O fugacities [3-5]. From these data metal-silicate partition coefficients may be calculated. The new data base allows predictions of metal-silicate partition coefficients at given temperatures and oxygen fugacities. In order to account properly for the composition of the silicate phase additional experiments with Fe, Ni and Co were performed using eucritic starting material (Millbillillie) as silicate phase. Experimental procedures

Evaporation Kinetics of Silicate Melt Evaporation of silicates and silicate melts is a key process to estimate time-dependent changes of physical and chemical conditions of the solar nebula. Although the origin of chondrules has been discussed on the basis of crystallization kinetics of silicate melts that were experimentally studied at 1 bar, crystallization kinetics of silicates in an open system govern the chemical and petrological characteristics of chondrules and matrixes, and thus may lead to a different scenario for

JMDMT #2364 Microfossils of Cyanobacteria in Carbonaceous Meteorites
The James M. DuPont Meteorite Collection - As this meteorite seems to have experienced weathering to a considerable degree, a high abundance of Br may be due to terrestrial contamination. Magnesium content of the Y 791093 silicate is about 20% lower than the H-chondrite average [2], yielding absolute abundances of the lithophiles that are systematically lower than the H-chondrite values by the same factor. Nickel-normalized siderophile abundances in the Y 791093 silicate are also chondritic. Their abundances are somewhat similar to EH chondrites, possibly influenced by the surrounding metal and/or sulfide. Thus, chemical composition of the silicate portion of Y 791093 is chondritic and therefore is considerably different from that for the silicate
