Enhancing the Discovery of Tabletop Games (open access)

Enhancing the Discovery of Tabletop Games

Collections of three-dimensional materials may not be discoverable to library users if they lack adequate metadata. Discovery of these collections may be enhanced through the application of relevant cataloging standards and con-trolled vocabularies. This paper outlines how librarians at the University of North Texas Libraries used these strategies to increase access to a large collection of tabletop games.

UV and infrared absorption spectra and 248 nm photolysis of maleic anhydride (C₄H₂O₃) (open access)

UV and infrared absorption spectra and 248 nm photolysis of maleic anhydride (C₄H₂O₃)

This article investigates maleic anhydride (C₂H₂(CO)₂O, Furan-2,5-dione) that is emitted into or formed in the atmosphere during bio-mass burning events as well as being a photochemical degradation product of some aromatic volatile organic compounds. The photochemical fate of maleic anhydride, however, is presently not well enough characterized to enable modeling of its impact on the environment and human health. In this study, the room temperature UV and infrared absorption spectra of maleic anhydride were measured and quantified using several complementary calibration methods.

Altitudinal gradients in Magellanic sub-Antarctic lagoons: the effect of elevation on freshwater macroinvertebrate diversity and distribution (open access)

Altitudinal gradients in Magellanic sub-Antarctic lagoons: the effect of elevation on freshwater macroinvertebrate diversity and distribution

In this article, freshwater macroinvertebrate diversity associated with lakes and ponds along the altitudinal gradient of a Magellanic sub-Antarctic watershed are assessed. A monotonic decline in species richness was observed with increasing elevation, with simpler and more even community composition at higher altitude. This pattern differs from the mid-peak trend found in streams of the same watershed. Functional feeding group structure also diminished with increasing elevation.

Examining Scientific Literacy through New Media (open access)

Examining Scientific Literacy through New Media

Article evaluates the impact of new media on scientific literacy. Content analysis with a coding scheme was performed on 42 filtered websites and 20 microblogs to analyze the role of new media in disseminating scientific knowledge. The results showed that the quality of science-oriented websites was higher than that of microblogs. Suggestions about how to improve the quality of science-oriented new media and how to develop students’ scientific literacy through new media are also discussed.

Algorithmically Optimized Hemispherical Dome as a Secondary Optical Element for the Fresnel Lens Solar Concentrator

This article focuses on a way to maximize the concentration acceptance product (CAP), while using the minimum SOE and receiver geometry at a given f-number and incidence angle (also referred to as the tracking error angle). The laws of polychromatic light refraction along with trigonometry and spherical geometry were utilized to optimize the POE grooves, SOE radius, receiver size, and SOE–receiver spacing.
