Abstract
The mechanical behaviour of an agricultural tyre is a matter of extreme interest as it is related to the comfort of operators, to the adherence of agricultural machines, and to the compaction of agricultural soil. Moreover, the deformability of the tyres plays a fundamental role in vehicle stability in terms of side rollover. The behaviour of a loaded tyre during its deformation is complex, due to the combined contributions of the carcass components, the tread rubber and the air contained within it. Therefore, this study proposes an experimental–numerical approach for the mechanical characterization of agricultural tyres based on real-scale experiments and matches these results with a finite-element (FE) model. The tyre flattening in the elastic field has been described using two coefficients (Young’s modulus “E”, Poisson’s ratio “ν”), whose values have been identified with an iterative FEM procedure. The proposed approach was applied to two different tyres (420/85 R24 and 460/85 R34), each one inflated at two different pressures (1.0 bar and 1.6 bar). Young’s modulus was appreciated to be highly variable with the inflation pressure “p” of the tyres. Furthermore, the response surface methodology was applied to find two mathematical regression models, useful for studying the variations of the tyre footprint dimensions according to the type of tyre. This simple approach can be applied in other simulations without suffering any loss of accuracy in the description of the phenomenon
Preface
No full textThe University of Pennsylvania Working Papers in Linguistics (PWPL) is an occasional series published by the Penn Graduate Linguistics Society. The series has included volumes of previously unpublished work, or work in progress, by linguists with an ongoing affiliation with the Department, as well as volumes of papers from NWAV and the Penn Linguistics Conference.
This volume contains selected papers accepted into the 44th Penn Linguistics Conference. This volume is exceptional insofar as PLC 44 was canceled due to the COVID-19 pandemic; we thank all authors accepted into PLC 44 for their patience and understanding. In an effort to give a panoramic view of the canceled conference, we decided to invite submissions both from authors of oral presentations (10-page papers) as well as poster presentations (5-page papers).
Thanks go to Faruk Akkuş, George Balabanian, Johanna Benz, Nikita Bezrukov, Pik Yu May Chan, Yiran Chen, June Choe, Ava Creemers, Gwen Hildebrandt, Wei Lai, Aini Li, Daoxin Li, Ollie Sayeed, Christine Soh, Ruicong Sun, and Yosiane White for their help in editing.
Since Vol. 14.2, PWPL has been an internet-only publication. As of September 2014, the entire back catalog has been digitized and made available on ScholarlyCommons@Penn. Please continue citing PWPL papers or issues as you would a print journal article, though you may also provide the URL of the manuscript. An example is below:

She is a leading researcher of the Institute for Scientific Information on Social Sciences of the Russian Academy of Sciences (INION RAN, in Russian), professor at the National University of Science and Technology (MISiS) and at the GITR Film and Television School. She is also Deputy Director for Science at the Nicholas Roerich Museum of the International Centre of the Roerichs, President of the International Association for Semiotics of Space and Time (IASSp+T, Switzerland), and Honorary Member of the Russian Academy of Arts. Fulbright grantee (2021) at the University of North Carolina at Chapel Hill and the University of Texas at Austin. Author of over 180 publications, including the monograph: Spaces and Meanings: Semantics of the Cultural Landscape (Springer, 2019). She is the author of the long-term interdisciplinary scientific project “The Geography of Art” (since 1992, 10 collections were published and 7 conferences were held). The project considers the territorial problems of culture and art, reflected in the art of the geographical space, the role of regional factors in the formation of art schools and artworks. Particular attention is given to topics such as artistic perception of the cultural landscape, the place of art in shaping the cultural landscape and the image of the territory, as well as the concepts of space in works of art. She is also the author of the long-term interdisciplinary scientific project “Russia and the East: the interaction in art” (since 2018, 2 conferences were held and 1 collection was published).</p>

Aisopou Mythoi
No full textThis is one of three 16-page large-format pamphlets in a series. The series is typified by blank cover backgrounds featuring Aisopou Mythoi at the top, identical monochrome inside-covers of an ass reading Aesop's fables to other animals, and a last page giving a moral under a repeat of the fable's title at its top. Bibliographical information is sparse, and I can find no indication how many books might be in the series. This volume's version of this story has a mouse, rather than the usual weasel, squeeze through a crack to get food but then find out that he cannot get out again until he grows thin again. In a great last two-page image, a human hand grasps him by the tail and lifts him up while buttons burst from his stretched trousers. Does that title translate The Gluttonous Mouse?Language note: Modern GreekAlexandros Krasokeras

Bibliographical information is sparse, and I can find no indication how many books might be in the series. The library's bibliographer sums up the story well: An ailing farmer tricks his sons into working in his vineyard. The artist here does a good job of making the sons' faces particularly dopey through most of the story. That quality sets up the good last two-page spread, where they are smiling and laughing with each other in front of money bags..Language note: Modern GreekAlexandros Krasokeras
