Jeans Day a success, says Steiner

Despite some student opposition and organizational problems, Friday\u27s Gay Blue Jeans Day was termed a success by one club member. There seemed to be many people wearing jeans and not as many counter-protesters as last year, said Tim Lane, a member of the Wilde-Stein Club, UMO\u27s homosexual organization. Last year there was much more opposition to the event

Blazing The Trail For Astronomy Education Research

Education research has long considered student learning of topics in astronomy and the space sciences, but astronomy education research as a sub-field of discipline-based education research is relatively new. Driven by a growing interest among higher education astronomy educators in improving the general education, introductory science survey course for non-science majoring undergraduates (“ASTRO 101”), contemporary astronomy education research is led by scholars with significant expertise in astronomy content. In this review, we outline the recent history of the growing field of discipline-based astronomy education research by analyzing graduate degrees earned, faculty involved, and major milestones, such as the appearance of archival, peer-reviewed professional journals. Astronomy education research as a field of discipline-based education research has made notable strides in the past few decades that distinguish it from the K-12 education research realm, and, in spite of some setbacks, continues to move forward as a growing and vibrant community of scholars

Effect of trace dissolved oxygen on the cathodic kinetics of carbon dioxide corrosion of carbon steel.

Summary: The corrosion of carbon steel in carbon dioxide saturated brine solutions is controlled by a mixed activation-mass transfer process in the cathodic reaction mechanism. Cathodic polarisation curves of carbon steel in carbonic acid solutions exhibit a limiting current behaviour that is dependent on the rate of mass transfer. In studies using the jet impingement technique, the magnitude of this limiting current behaviour has been found to be strongly affected by the presence of trace levels of dissolved oxygen. This paper presents a theoretical assessment of the mass transfer limited cathodic current to illustrate the pronounced effect of dissolved oxygen contamination <15ppb. Discussion is presented regarding the implications of dissolved oxygen contamination on the interpretation of the mechanism of carbon dioxide corrosion

Flow Dependence of Carbon Dioxide Corrosion Using Short Electrodes by Jet Impingement

The jet impingement technique is a valuable methodology for the evaluation of carbon dioxide corrosion and inhibition under high flow velocities. This technique commonly employs short electrodes that remain within a region of the developing diffusion boundary layer induced by the reactively corroding surface. The employment of such electrodes has been associated with the poor correlation of corrosion rates determined from field and laboratory measurements by various apparatus. This paper presents an investigation into the flow relationship of the carbon dioxide corrosion mechanism in non-scaling synthetic brine solutions at 30 C with a carbon dioxide partial pressure of 1.88 bar. The effect of the developing diffusion boundary layer on the corrosion rate and its dependence on the flow velocity is investigated by jet impingement using dissimilar electrode lengths in the flow direction.It is shown that the measured corrosion rate is dependent on the state of development of the diffusion boundary layer with a relationship that is contrary to the average rate of mass transfer. A more developed diffusion boundary layer exhibits a greater rate of carbon dioxide corrosion at a lower average mass transfer than in a developing diffusion boundary layer with a higher average mass transfer. This phenomenon illustrates an antagonistic effect of the diffusion boundary layer on the mechanism of carbon dioxide corrosion that is likely to strongly influence the correlation of corrosion rates obtained using various laboratory apparatus and field applications

A Winogradsky-based culture system shows an association between microbial fermentation and cystic fibrosis exacerbation.

There is a poor understanding of how the physiology of polymicrobial communities in cystic fibrosis (CF) lungs contributes to pulmonary exacerbations and lung function decline. In this study, a microbial culture system based on the principles of the Winogradsky column (WinCF system) was developed to study the physiology of CF microbes. The system used glass capillary tubes filled with artificial sputum medium to mimic a clogged airway bronchiole. Chemical indicators were added to observe microbial physiology within the tubes. Characterization of sputum samples from seven patients showed variation in pH, respiration, biofilm formation and gas production, indicating that the physiology of CF microbial communities varied among patients. Incubation of homogenized tissues from an explant CF lung mirrored responses of a Pseudomonas aeruginosa pure culture, supporting evidence that end-stage lungs are dominated by this pathogen. Longitudinal sputum samples taken through two exacerbation events in a single patient showed that a two-unit drop in pH and a 30% increase in gas production occurred in the tubes prior to exacerbation, which was reversed with antibiotic treatment. Microbial community profiles obtained through amplification and sequencing of the 16S rRNA gene showed that fermentative anaerobes became more abundant during exacerbation and were then reduced during treatment where P. aeruginosa became the dominant bacterium. Results from the WinCF experiments support the model where two functionally different CF microbial communities exist, the persistent Climax Community and the acute Attack Community. Fermentative anaerobes are hypothesized to be the core members of the Attack Community and production of acidic and gaseous products from fermentation may drive developing exacerbations. Treatment targeting the Attack Community may better resolve exacerbations and resulting lung damage

ARIES: A Corpus of Scientific Paper Edits Made in Response to Peer Reviews

Revising scientific papers based on peer feedback is a challenging task that requires not only deep scientific knowledge and reasoning, but also the ability to recognize the implicit requests in high-level feedback and to choose the best of many possible ways to update the manuscript in response. We introduce this task for large language models and release ARIES, a dataset of review comments and their corresponding paper edits, to enable training and evaluating models. We study two versions of the task: comment-edit alignment and edit generation, and evaluate several baselines, including GPT-4. We find that models struggle even to identify the edits that correspond to a comment, especially in cases where the comment is phrased in an indirect way or where the edit addresses the spirit of a comment but not the precise request. When tasked with generating edits, GPT-4 often succeeds in addressing comments on a surface level, but it rigidly follows the wording of the feedback rather than the underlying intent, and includes fewer technical details than human-written edits. We hope that our formalization, dataset, and analysis will form a foundation for future work in this area.Comment: 11 pages, 2 figure
