Otto Mainzer Collection. late 1800s-2003 bulk 1922-1998
No full textThe Otto Mainzer collection documents the life and professional activities of Otto Mainzer, lawyer, writer, and financial consultant; the collection also sheds light on the life of Otto Mainzer’s wife, Ilse Wunsch, a musician and a teacher. The collection includes correspondence, financial, vital, immigration, and legal documents, notes, photographs, printed materials, and writings, by Otto Mainzer and Ilse Wunsch as well as a small number of manuscripts by other authors. The collection is divided into two distinct sections, one pertaining to Otto Mainzer and the other to Ilse Wunsch.Otto Mainzer, lawyer, writer, and a financial consultant was born in 1903 in Frankfurt am Main. He received his basic schooling in Frankfurt am Main and continued his education at Frankfurt, Munich, and Berlin universities, studying jurisprudence. After receiving his degree Otto Mainzer worked as a lawyer at the Berlin Court of Appeals. He immigrated to Paris in 1933 where he devoted his time to writing. It was in Paris that he began working on his monumental work of non-fiction, Die sexuelle Zwangswirtschaft: ein erotisches Manifest, which he eventually managed to publish in 1981. In the mid-thirties Otto Mainzer published one volume of poems entitled, Der zaertliche Vorstoss: in sechsundsechzig Gedichten. During the same period he wrote his first novel, Prometheus. He had to wait for forty years before it was published by Stroemfeld/Roter Stern in 1989. After the outbreak of World War II in 1939 Otto Mainzer was interned at a French concentration camp for over a year before being allowed to leave. He arrived in New York in late 1941. Shortly after his arrival, Otto Mainzer moved to Chicago to work as a graphologist for the Spiegel of Chicago. It was in Chicago that he met his future wife, Ilse Wunsch. Soon after Otto Mainzer and Ilse Wunsch moved back to New York. Otto Mainzer devoted the rest of his life to writing and propagating his ideas of human love and sexuality as an underlying stratum for all of the human interactions. The bulk of Otto Mainzer’s written legacy was never published. He died in New York in 1995.Ilse Wunsch was born in 1911 in Berlin, Germany. She started studying piano at a very early age. After graduating from high school, Ilse Wunsch continued her studies at the Teachers Training College. In 1936 she left for Japan, for concertizing and teaching. She eventually moved to Chicago where she continued her studies at the Chicago Musical College, in due course earning a Master of Music degree. After meeting Otto Mainzer, the couple moved to New York, where Ilse resumed her post graduate studies. In New York, Ilse Wunsch was a member of the faculty of the New York College of Music, Stern College for Women, teaching piano and theory. Later she became an Assistant Professor at New York University, School of Education, Music Education Division. Ilse Wunsch was also an author of a number of books on music theory and pedagogy; she also composed a number of music pieces; and finally she wrote autobiographical non-fiction dedicated to her husband, Otto Mainzer.Otto Mainzer's collection of poems "Der zaertliche Vorstoss in sechsundsechzig Gedichten" is available in the LBI library (r PT 2613 R825 Z3).Processeddigitize
Nonionoides n. gen. demens (Bık, 1964), eine bisher verkannte Foraminiferenart aus dem Aquitan des Mainzer Beckens
No full textInvestigations on the systematic position of the foraminifer generally refered
to as Hastigerina demens known from the Aquitanian of the Mayence basin have shown,
that a new classification has to be made.
Based on the shown protoforamina the species has to be considered as belonging to the
family Polystomellidae EIMER & FICKERT, 1899. The aberrant test of the species which above
all appears in the evolute arrangement of the chambers, has induced the author to
place the species in a new genus Nonionoides n. gen.
For N. demens a benthonic way of life has to be assumed. Therefore no autochthon
planctonic living foraminifers are known from the Hydrobia beds and Corbicula beds of the
Mainz basin.researc

Asteroid-Meteorite Linkages through Infrared Spectroscopy
No full textAsteroids are cosmic puzzles. Meteorites can serve as puzzle pieces to help construct geochemical context of the Solar System and are also pieces derived from asteroids. Ordinary chondrites are the most common types of meteorites that arrive to Earth and are composed of three subtypes: H, L and LL chondrites. Meteorites that have undergone complex melting and geological changes, named the achondrites, provide clues towards the foundation and patterns of planetary formation. Understanding both ordinary chondrite and achondrite meteorites creates the criteria in which their parent asteroids must also possess. A result of this work is affirming that asteroid-meteorite linkages can be established through infrared spectroscopy.
The Gefion Asteroid Family (GAF) has been proposed to be the source asteroids for the L chondrite meteorites. In this thesis results are presented for 18 dynamically defined members of the GAF through a near-infrared (0.7-2.5 micrometers (µm)) spectroscopic survey. These results are presented to test the hypothesis that L-chondrites originate from this family (McGraw et al. 2018, 2022). Compositional analysis of these asteroids shows a range of meteorite analogs for the entire ordinary chondrite range of H-, L-, and LL, and possibly the subcategory of L/LL chondrites.
The anomalous achondrite meteorite Northwest Africa (NWA) 6704 has basaltic texture and silicate mineralogy. However, NWA 6704 also shows isotopic consistencies with other carbonaceous chondrite meteorites (McGraw et al. 2020). The spectral data of the achondrite meteorite clan known as the howardites, eucrites, and diogenites (HEDs) are also of basaltic nature and are derived from asteroid (4) Vesta. Problematically, the HEDs and anomalous achondrites share similar spectral absorption features. Thus, searching for the parent asteroid sources for geologically evolved achondrites that may be hidden amongst the V-type asteroid population is an important goal within planetary science. A portion of this thesis work investigates multiwavelength spectroscopy (0.35-25 µm) in order to determine spectral diagnostic features and differences from other achondrite meteorites such as the HEDs

Activity and the Evolutionary State of Small Bodies
No full textThe study of the Solar System's remnant planetesimals is motivated by their connection with their formation conditions in the proto-Solar disk. The discovery of the active Centaurs and Main Belt Comets over the past few decades has made it clear that far more objects are go through phases of activity than previously estimated, and often through activity mechanisms that are poorly understood. The critical knowledge gap is thus understanding how activity changes the properties of these small bodies and how to interpret their modern properties to understand their recent evolution. This Dissertation improves our ability to ``roll back the clock" on these small bodies through telescopic observations, dynamical simulations, and laboratory experiments relevant to nine objects at different evolutionary and activity states to assess how changes in activity alter the properties of these objects. Telescopic observations of two Geminid Complex objects, (3200) Phaethon and (155140) 2005 UD, reveal Phaethon's surface to be rotationally homogeneous but different from UD's. I heated samples of the CI Chondrite Orgueil to successively higher temperatures to compare with the reflectance spectra of these objects and constrain their recent thermal evolution. Laboratory spectra at Phaethon's perihelion temperature were quite similar to Phaethon, but no match was found for UD. Observations of the nuclei of four (nearly-) dormant traditional comets, including the Quadrantid parent (196256) 2003 EH, show them to have a large variation in surface properties. Dormant Main Belt Comets might be distinguishable from dormant traditional comets, but thermal alteration might play a complicating role for some objects. Orbital simulations and new multi-wavelength telescopic observations of two active Centaurs, 174P/Echeclus and P/2019 LD2 (ATLAS), show them to have very different activity patterns and recent orbital evolutions. Echeclus's activity is dominated by strong, short-lived outbursts, while LD2's activity is weak and stable in time. LD2's recent orbital change might have initiated its activity, but Echeclus has had no significant recent orbital changes. I also present and analyze observations of the interstellar comet 2I/Borisov, which reveal it to be compositionally distinct from many Solar System comets despite many clearly similar ongoing chemical processes

Connecting Points in Time: From the Evolution of Clouds in Substellar Atmospheres to Students’ Perceptions of Earth’s Place in the Universe
No full textEqually as important as growing the body of human knowledge through scientific discoveries and analysis is relaying this information to the general public in a digestible manner to establish a scientifically literate society. This dissertation approaches the multifaceted issue by combining an in-depth study of brown dwarf binary atmospheres with an astronomy education component. Thus, the goal of this work is twofold: to improve our current understanding of clouds in brown dwarf atmospheres and to identify preconceptions non-science undergraduate students posses about Earth's place in time and space in the Universe.
The first portion of the dissertation seeks to constrain atmospheric and cloud properties in a sample of well-known brown dwarf binaries. I answer this question using spatially-resolved optical and near-infrared photometry from the Hubble Space Telescope (HST) and the W. M. Keck Telescopes to explore cloud properties in detail across a broad range of effective temperatures and surface gravities. New grids of synthetic spectra were created using the PHOENIX atmosphere model code, extending clouds to deeper pressures and smaller mean grain sizes. I report bulk atmospheric properties with trends in cloud location and mean grain size for mid-L through mid-T type brown dwarfs (Chapter 2). The results of this study led to a detailed analysis in Chapter 3 of an individual triple system, HD 130948, containing a solar analogue star and two brown dwarfs of similar mass, luminosity, and spectral type. Moderate-resolution spectroscopy from the OSIRIS instrument on Keck was fit to synthetic spectra to determine the best-fitting atmosphere parameters of HD 130948B and HD 130948C for solar and stellar metallicity. I measure the C/O ratio of each binary and confirm it is consistent with the host star.
In the second component (Chapter 4), I investigate students' conceptions of time in astronomy as it relates to Earth's formation and location in the Universe. A set of open-ended questions were developed and issued to a sample of students in an astronomy course. Thematic analysis of the responses suggested students struggle with fundamental topics in astronomy related to the origin and formation of the Universe, planet formation, the age of the Universe and Earth, and the composition and structure of the Universe. Incorporating explicit discussion and instruction regarding time in astronomy can be a useful tool toward improving non-science students' grasp of difficult, abstract concepts in introductory astronomy courses

The Effect of Dust in Small Bodies: A Sample of Jupiter Family Comets
No full textThere was an unprecedented opportunity to study the inner dust coma environment, where the dust and gas are not entirely decoupled, of Jupiter Family Comets 45P/Honda-Mrkos-Pajdusakov (45P/HMP) from Dec. 26, 2016 - Mar. 15, 2017, 41P/Tuttle-Giacobini-Kresak (41P/TGK) from Feb. 16, 2017 - May 23, 2017, and 46P/Wirtanen from Nov. 10, 2018 - Feb. 13, 2019, in visible wavelengths. During that time period, we also had the opportunity to observe an additional Jupiter Family Comet, 21P/Giacobini-Zinner during its 2018 perihelion passage using narrowband CN photometric imaging, which did not approach Earth as drastically but did provide ample information for a detailed periodicity study. We also had the opportunity to analyze archival data of approximately 180 NEAs taken with the Arecibo Planetary Radar System. We find that 21P/GZ has a period of 10.7 +- 0.2 hours. We measured a lower limit on the CN outflow velocity for the Northern Jet of 1.0 +- 0.1 km s^-1 and for the Southern Jet of 0.8 +- 0.1 km s^-1. In addition, we analyze the morphologies of the jet features and determine that northern pointing jet takes the shape of a corkscrew while the southern pointing is heavily influenced by solar radiation pressure. The azimuthally averaged dust radial profile slope of comet 45P/HMP gradually changes from -1.81+- 0.20 at 5.24 days pre-perihelion to -0.35 +- 0.16 at 74.41 days post perihelion. Contrastingly, the radial profile slope of 46P/Wirtanen stays fairly constant over the observed time period at -1.05 +- 0.05. We also find that 41P/TGK's dust radial profile slope changes from steeper than -1 pre-perihelion to shallower near perihelion, then possibly steepens again. Finally, we find that different asteroid types have vastly different radar albedo, specifically E-type and V-type asteroids
