Review of \u3ci\u3eWilla Cather: A Bibliography\u3c/i\u3e By Joan Crane

In Willa Cather: A Bibliography, Joan Crane has surpassed our fondest hopes for a bibliography that would establish and describe the Cather canon. This is a volume that will be invaluable to collectors and booksellers, textual critics, and literary scholars. By following rigorous standards of analytical description, Crane provides the specialized information that booksellers, private persons, and librarians need to collect and preserve Cather\u27s printed writing. Ordinarily, the needs of the collector, who focuses on physical characteristics, seem different from those of the literary scholar, who focuses on content. But this separation is neither so easy nor so clear for Cather, who was actively involved in the publication of her books. She participated in their design-in the selection of paper stock, color, type style; she made major decisions, such as choosing W. T. Benda as the illustrator for My Antonia and working with him in the conception, execution, and printing of the illustrations; she oversaw more minor details, such as the placement of a note in Sapphira and the Slave Girl. Because Cather took such an active role in the publishing of her books, their physical characteristics have an authority relevant to interpretations of them. Willa Cather: A Bibliography will be of interest to literary scholars in other ways, for Crane went beyond strict limitations of formal descriptive bibliography, writing, it was my intention that the letter of the rule be observed, but, inevitably, I have strayed into proscribed bypaths. With no desire to give scandal to the orthodoxy of my profession, I wished nevertheless to express something beyond the mere accidence of the books. It is fortunate for us that she did, for her descriptions and, especially, her discursive histories of publications provide rich research possibilities. Crane treats some special enigmas such as Cather\u27s involvement in writing the Mary Baker Eddy biography, her authorship but not invention of the S. S. McClure biography, the permutations in the plates of A Lost Lady, and the disordering of texts in Death Comes for the Archbishop. Beyond providing descriptive information on individual editions, Willa Cather: A Bibliography establishes the Cather canon to date. Crane includes all separate publications, collections, poems, short fiction, articles, reviews, and essays in newspapers and periodicals; introductions, prefaces, and contributions to books; personal letters, statements, and quotations printed or reproduced; and works edited by Cather. In so doing, she demonstrates the wide range and sheer bulk of Cather\u27s writing, and she draws attention to certain gaps in the scholarship. For example, she rightly includes a section on Cather\u27s editing, an aspect of Cather\u27s career that has received little attention, yet that includes work that was Cather\u27s own in execution if not in invention. Finally, Crane lists all forms by which Cather\u27s works have been presented: translations of novels and stories, foreign editions, large-type books, books for the blind, and adaptations on film and for theater. Cather had a firm aesthetic sense of a book, and it is fitting that this book about her books should excel in this respect also. Designed by Richard Eckersley of the University of Nebraska Press, Willa Cather: A Bibliography was selected by the American Institute of Graphic Arts for its annual traveling exhibition of the best designed and produced books from American publishers in 1982. In short, this is a superb volume. Cather studies are-and will be-the richer for it

Atomic layer deposition on porous powders with in situ gravimetric monitoring in a modular fixed bed reactor setup

This article appeared in Review of Scientific Instruments 88, 074102 (2017) and may be found at https://doi.org/10.1063/1.4992023.A modular setup for Atomic Layer Deposition (ALD) on high-surface powder substrates in fixed bed reactors with a gravimetric in situ monitoring was developed. The design and operation are described in detail. An integrated magnetically suspended balance records mass changes during ALD. The highly versatile setup consists of three modular main units: a dosing unit, a reactor unit, and a downstream unit. The reactor unit includes the balance, a large fixed bed reactor, and a quartz crystal microbalance. The dosing unit is equipped with a complex manifold to deliver gases and gaseous reagents including three different ALD precursors, five oxidizing or reducing agents, and two purge gas lines. The system employs reactor temperatures and pressures in the range of 25-600 °C and 10−3 to 1 bar, respectively. Typically, powder batches between 100 mg and 50 g can be coated. The capabilities of the setup are demonstrated by coating mesoporous SiO2 powder with a thin AlOx (submono) layer using three cycles with trimethylaluminium and H2O. The self-limiting nature of the deposition has been verified with the in situ gravimetric monitoring and full saturation curves are presented. The process parameters were used for a scale-up in a large fixed bed reactor. The samples were analyzed with established analytics such as X-ray diffraction, N2 adsorption, transmission electron microscopy, and inductively coupled plasma optical emission spectrometry.DFG, 53182490, EXC 314: Unifying Concepts in Catalysi

On the Complexity of Diameter and Related Problems in Permutation Groups

We prove that it is ??^?-complete to verify whether the diameter of a given permutation group G = ?A? is bounded by a unary encoded number k. This solves an open problem from a paper of Even and Goldreich, where the problem was shown to be NP-hard. Verifying whether the diameter is exactly k is complete for the class consisting of all intersections of a ??^?-language and a ??^?-language. A similar result is shown for the length of a given permutation ?, which is the minimal k such that ? can be written as a product of at most k generators from A. Even and Goldreich proved that it is NP-complete to verify, whether the length of a given ? is at most k (with k given in unary encoding). We show that it is DP-complete to verify whether the length is exactly k. Finally, we deduce from our result on the diameter that it is ??^?-complete to check whether a given finite automaton with transitions labelled by permutations from S_n produces all permutations from S_n

The influence of the chain length and the functional group steric accessibility of thiols on the phase transfer efficiency of gold nanoparticles from water to toluene

The papers were published with the financial support from the budget of the West Pomeranian Voivodeship.This paper describes the influence of the chain length and the functional group steric accessibility of thiols modifiers on the phase transfer process efficiency of water synthesized gold nanoparticles (AuNPs) to toluene. The following thiols were tested: 1-decanethiol, 1,1-dimethyldecanethiol, 1-dodecanethiol, 1-tetradecanethiol and 1-oktadecanethiol. Nanoparticles (NPs) synthesized in water were precisely characterized before the phase transfer process using Atomic Force Microscopy (AFM) and Transmission Electron Microscopy (TEM). The optical properties of AuNPs before and after the phase transfer were studied by the UV-Vis spectroscopy. Additionally, the particle size and size distribution before and after the phase transfer of nanoparticles were investigated using Dynamic Light Scattering (DLS). It turned out that the modification of NPs surface was not effective in the case of 1,1-dimethyldecanethiol, probably because of the difficult steric accessibility of the thiol functional group to NPs surface. Consequently, the effective phase transfer of AuNPs from water to toluene did not occur. In toluene the most stable were nanoparticles modified with 1-decanethiol, 1-dodecanethiol and 1-tetradecanethiol.This work was supported by FP7-NMP-2010-SMALL-4 program (HYMEC), project number 263073.

Effects of 5-aza-2´-deoxycytidine on primary human chondrocytes from osteoarthritic patients

Chondrocytes, comparable to many cells from the connective tissue, dedifferentiate and end up in a similar fibroblastoid cell type, marked by the loss of the specific expression pattern. Here, chondrocytes isolated from osteoarthritic (OA) patients were investigated. The OA chondrocytes used in this work were not affected by the loss of specific gene expression upon cell culture. The mRNA levels of known cartilage markers, such as SOX5, SOX6, SOX9, aggrecan and proteoglycan 4, remained unchanged. Since chondrocytes from OA and healthy tissue show different DNA methylation patterns, the underlying mechanisms of cartilage marker maintenance were investigated with a focus on the epigenetic modification by DNA methylation. The treatment of dedifferentiated chondrocytes with the DNA methyltransferase inhibitor 5-aza-2´-deoxycytidine (5-aza-dC) displayed no considerable impact on the maintenance of marker gene expression observed in the dedifferentiated state, while the chondrogenic differentiation capacity was compromised. On the other hand, the pre-cultivation with 5-aza-dC improved the osteogenesis and adipogenesis of OA chondrocytes. Contradictory to these effects, the DNA methylation levels were not reduced after treatment for four weeks with 1 μM 5-aza-dC. In conclusion, 5-aza-dC affects the differentiation capacity of OA chondrocytes, while the global DNA methylation level remains stable. Furthermore, dedifferentiated chondrocytes isolated from late-stage OA patients represent a reliable cell source for in vitro studies and disease models without the need for additional alterations.DFG, 414044773, Open Access Publizieren 2019 - 2020 / Technische Universität Berli
