Nitrogen abundances from UV lines of HgMn and standard late-B stars

A recent survey by Roby (1987) discovered that the relatively weak high excitation lines of N 1 near 7468 and 8680 A were undetectable in the majority of HgMn stars, leading to upper limits on the N abundance of roughly ten times below that of the solar N abundance. Standard stars with similar temperatures (10,000 to 13,000 K) did exhibit these same N lines and were found to have roughly solar N abundances. The N abundances were redetermined in two HgMn stars and four standard stars using the strong, low excitation lines of N 1 found in the ultraviolet. The observational data consisted of high quality, high resolution, co-added International Ultraviolet Explorer spectra which was previously collected and reduced. Examination of the spectra plus considerations of signal/noise and severe line blending led to the choice of three promising N 1 lines located at 1742.7, 1745.3 and 1411.9 A. The atomic data for these lines were previously calculated using the best laboratory measurements found in a search of the relevant literature. The chosen N lines turned out to be blended significantly with Fe 2 lines. To obtain the abundances for N synthetic spectra were computed to match the observed spectra. The synthetic spectra were calculated using lie-blanketed model atmospheres, stellar parameters, and abundances for the other elements based upon previous work by S. Adelman. The N abundance was then adjusted to give the best fit of the observed line profiles. In the 2 HgMn stars, the N lines were again found to be undetectable, but the stronger intrinsic strength of the new lines yield more stringent upper limits than those obtained previously. Model atmosphere and abundances were updated in two stars where new results were reported. An additional N 1 line and an additional standard star were added to the program. A line opacity model was developed for a missing feature adjacent to the N 1 line at 1745.2 A, leading to a 25 percent improvement in the determined from this line

Private Scandal in the Public Sphere: Sexual Scandal as Early Eighteenth-Century Polemics

Changes in literary strategies and polemical contest in the early eighteenth century legitimized the use of sexual scandal as a means of attack in the mainstream commercial press. Authors embraced scandal to obscure and temper partisan conflicts that motivated animosities, and in doing so they sanctioned inquiry into the private lives of public figures. This strategic use of scandal emerged as a reaction against the political–religious polemics of the English civil war of the mid 1600s. The discourse of scandal developed as an alternative to the discourse of politeness, which similarly evaded explicitly partisan exchanges. Instead of using politeness to cultivate decorous public debate, some authors turned to scandalous (often calumnious) exposés because it allowed them to veil troubling conflicts while still venting animosities. Chapter One examines how early modern sexual libels were transformed after the civil war. I show how in The Rehearsal Transpros’d Andrew Marvell adapted these precedents into his religious polemics; he redirected them against a quasi–public target, the Anglican cleric Samuel Parker, in order to ridicule Parker as an individual. Chapter Two demonstrates how Delarivier Manley perfected this strategy of obfuscation in The New Atalantis. At moments of political crisis throughout the text, Manley’s political narrative pivots towards amatory encounters to distract readers from the crisis at hand. By casting her political tract as a sexual allegory, she legitimized the personalization, privatization and sexualization of political discourse. As Chapter Three illustrates, in the Tatler and Spectator Joseph Addison and Richard Steele repudiated the public’s appetite for scandal, but their very censures reflect that scandalous discourse permeated public debate. Although known for shaping the public sphere, in denouncing scandal, they revealed skepticism of the public’s ability to engage in rational dialogue. Chapter Four shows that Alexander Pope and his literary rivals adapted scandal as a means of satiric attack against each other—that is, against private figures in the public eye—to undermine one another’s cultural standing. I reveal the buried political–religious conflicts that motivated these hostilities, and I demonstrate that Pope refined his use of scandal as a literary tool throughout his career

Optimasi Massa Rangka Kendaraan Elektrik Pengangkut Sampah Dengan Simulasi Metode Elemen Hingga

Residential waste contributes up to 55% of the total volume of urban waste such as in Jakarta. It makes the transport process of residential waste to temprorary landfill site (TPS) that has been existed, less efficient. Transporting waste process with garbage cart is depended on the manpower, while with the garbage truck, the vehicle's width and the use of fossil fuels are the weaknesses. Thus, the design concept of a waste transport vehicle using electric motor as driving source is made which has the same payload capacity as a garbage cart in general. Garbage payload along with the main components must be strongly supported by the vehicle frame, which incidentally serves as the support vehicle. In this study, discussed the optimization of electric waste transport vehicle with the help of 3-dimensional CAD modelling, then simulated with static loading to obtain the results of the stress, displacement with the maximum value and location, and can assign the payload distribution position. With variable of the beam profile shape and its thickness, then obtained the optimal order forms, which frame weighs as light as possible but still robust in supporting given loads, which is frame with a cylindrical hollow profile with diameter of 60.3 mm and thickness of 4 mm

Ternary algebras and groups

We construct explicitly groups associated to specific ternary algebras which extend the Lie (super)algebras (called Lie algebras of order three). It turns out that the natural variables which appear in this construction are variables which generate the three-exterior algebra. An explicit matrix representation of a group associated to a peculiar Lie algebra of order three is constructed considering matrices with entry which belong to the three exterior algebra.Comment: 11 pages contribution to the 5th International Symposium on Quantum Theory and Symmetries (QTS5

Enhancing Science Return During the Rapid Expansion of IRSA

The NASA/IPAC Infrared Science Archive is undergoing a rapid expansion in the portfolio of missions for which we serve data, including the recent additions of the Spitzer Heritage Archive, the WISE archive, and NASA's Planck archive. This expansion has led to more than an order of magnitude increase in data holdings within a few years, and the inclusion of catalogs up to 10 billion rows. As a result, IRSA has a special opportunity to grow its services to support not only individual IR missions, but to optimize the synergy between them. We discuss the ways in which we enhance the science return from multiple IR data sets, including data discovery, moving object “precovery,” and image cross-comparison

Firefly: Embracing Future Web Technologies

At IPAC/Caltech, we have developed the Firefly web archive and visualization system. Used in production for the last eight years in many missions, Firefly gives the scientist significant capabilities to study data. Firefly provided the first completely web based FITS viewer as well as a growing set of tabular and plotting visualizers. Further, it will be used for the science user interface of the LSST telescope which goes online in 2021. Firefly must meet the needs of archive access and visualization for the 2021 LSST telescope and must serve astronomers beyond the year 2030. Recently, our team has faced the fact that the technology behind Firefly software was becoming obsolete. We were searching for ways to utilize the current breakthroughs in maintaining stability, testability, speed, and reliability of large web applications, which Firefly exemplifies. In the last year, we have ported the Firefly to cutting edge web technologies. Embarking on this massive overhaul is no small feat to say the least. Choosing the technologies that will maintain a forward trajectory in a future development project is always hard and often overwhelming. When a team must port 150,000 lines of code for a production-level product there is little room to make poor choices. This paper will give an overview of the most modern web technologies and lessons learned in our conversion from GWT based system to React/Redux based system

Halo orbit mission correction maneuvers using optimal control

This paper addresses the computation of the required trajectory correction maneuvers for a halo orbit space mission to compensate for the launch velocity errors introduced by inaccuracies of the launch vehicle. By combining dynamical systems theory with optimal control techniques, we are able to provide a compelling portrait of the complex landscape of the trajectory design space. This approach enables automation of the analysis to perform parametric studies that simply were not available to mission designers a few years ago, such as how the magnitude of the errors and the timing of the first trajectory correction maneuver affects the correction ΔV. The impetus for combining dynamical systems theory and optimal control in this problem arises from design issues for the Genesis Discovery Mission being developed for NASA by the Jet Propulsion Laboratory
