The Space Is a Service, Too : Library Commons & Access Services

Presented at the Access Services Conference 2009, November 11 - 13, 2009, Georgia Institute of Technology, Georgia Tech Global Learning Center, Atlanta, Georgia.What happens when an access services department has to run an information commons? This presentation will describe the transformation of the Georgia Tech Library's Circulation department when they became the service desk for the Library East Commons, including: how the staff adapted to new job requirements; how the department philosophy influenced the daily activities in the commons; and how the commons created partnerships with other library and academic departments.Georgia Institute of Technology Library and Information Center; Georgia State University Library; Georgia Gwinnett College Librar

Mechanical modelling quantifies the functional importance of outer tissue layers during root elongation and bending

Root elongation and bending require the coordinated expansion of multiple cells of different types. These processes are regulated by the action of hormones that can target distinct cell layers. We use a mathematical model to characterise the influence of the biomechanical properties of individual cell walls on the properties of the whole tissue. Taking a simple constitutive model at the cell scale which characterises cell walls via yield and extensibility parameters, we derive the analogous tissue-level model to describe elongation and bending. To accurately parameterise the model, we take detailed measurements of cell turgor, cell geometries and wall thicknesses. The model demonstrates how cell properties and shapes contribute to tissue-level extensibility and yield. Exploiting the highly organised structure of the elongation zone (EZ) of the Arabidopsis root, we quantify the contributions of different cell layers, using the measured parameters. We show how distributions of material and geometric properties across the root cross-section contribute to the generation of curvature, and relate the angle of a gravitropic bend to the magnitude and duration of asymmetric wall softening. We quantify the geometric factors which lead to the predominant contribution of the outer cell files in driving root elongation and bending

Arabidopsis antibody resources for functional studies in plants

© 2020, The Author(s). Here we report creation of a unique and a very valuable resource for Plant Scientific community worldwide. In this era of post-genomics and modelling of multi-cellular systems using an integrative systems biology approach, better understanding of protein localization at sub-cellular, cellular and tissue levels is likely to result in better understanding of their function and role in cell and tissue dynamics, protein–protein interactions and protein regulatory networks. We have raised 94 antibodies against key Arabidopsis root proteins, using either small peptides or recombinant proteins. The success rate with the peptide antibodies was very low. We show that affinity purification of antibodies massively improved the detection rate. Of 70 protein antibodies, 38 (55%) antibodies could detect a signal with high confidence and 22 of these antibodies are of immunocytochemistry grade. The targets include key proteins involved in hormone synthesis, transport and perception, membrane trafficking related proteins and several sub cellular marker proteins. These antibodies are available from the Nottingham Arabidopsis Stock Centre

1935 The Freshman, vol. 2, no. 13

The Freshman was a weekly, student newsletter issued on Mondays throughout the academic year. The newsletter included calendar notices, coverage of campus social events, lectures, and athletic teams. The intent of the publication was to create unity, a sense of community, and class spirit among first year students. The front page of issue 13 is dedicated in memoriam of Emile J. Dawson (1910-1932), who died from a cerebral hemorrhage after he struck his head on a concrete floor at the Armory, knocked down by his opponent in an intramural boxing tournament
