Parthenocarpic Cucumber Cultivar Evaluation In High-Tunnel Production, Wenjing Guan, Elizabeth Maynard, Bronwyn Aly, Julie Zakes, Dan Egel, Laura Ingwell

Department of Horticulture & Landscape Architecture Faculty Publications

Fresh-consumed parthenocarpic cucumbers (Cucumis sativus) are a popular and high-value crop sold in local food markets. The parthenocarpic plant characteristics and climbing growth habit make cucumbers an ideal crop for high-tunnel production. Major types of parthenocarpic cucumbers include Beit alpha and mini, Dutch greenhouse, American slicer, and Japanese. Information regarding yield performance, plant growth, and disease resistance of the four types grown in high-tunnel conditions is limited. In this study, 16 parthenocarpic cucumber cultivars from the four major types were evaluated in high tunnels at three locations in Indiana and Illinois during Spring 2018. Plants were pruned to …

Study On Thecone Programming Reformulation Of Active Noise Control Filter Design In The Frequency Domain, Yongjie Zhuang, Yangfan Liu

Publications of the Ray W. Herrick Laboratories

In the practice of active noise control, the control filter can be designed in either the time domain or the frequency domain. Compared with the former method category, it is more convenient to use frequency-domain methods to apply constraints such as stability, robustness, disturbance enhancement, input limit of loudspeakers, etc. Better noise reduction performance can usually be achieved by frequency-domain design as well. However, the computational complexity of designing a filter in the frequency domain is usually significant, especially for multichannel systems with multiple constraints. This is one of the challenges of using frequency-domain design in practical applications. In this …

Poro-Elastic Materials And The Control Of Low Frequency Sound, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

In the introductory sections of active noise control and metamaterial articles, it is often said that “conventional”, i.e., poro-elastic materials such as foams and fibrous media, do not work well at low frequencies. While that observation may be true for the simplest treatments, e.g., a single layer of a homogeneous, limp fibrous layer, there are many cases in which excellent weight and cost-effective acoustical treatments can be realized by using poro-elastic media. The first example involves the serendipitous discovery of a configuration that allows a 25 mm thick foam layer to provide effective absorption at 300 Hz, at a surface …

A Review Of Theories For Sound Transmission Through Infinite Double Panels And Identification Of Asymptotic Behavior, Zhuang Mo, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

In this paper, existing theories for sound transmission through infinite, double panel systems are first reviewed with a view to identifying their differences. The review begins from the classic papers of Beranek and Work, and London, before going on to consider later work by Mulholland, Parbrook and Cummings, Heckl, Fahy, and Hamada and Tachibana. The sound transmission problem was framed as a boundary value problem by most of these authors, except for Mulholland et al. who derived a multiple-reflection theory, and Hamada and Tachibana who introduced a transfer matrix approach. Further, except for Heckl’s model, in which a locally-reacting medium …

The Dehumanization Of Immigrants And Refugees: A Comparison Of Dehumanizing Rhetoric By All Candidates In Three U.S. Presidential Elections, Amanda Warnock

The Journal of Purdue Undergraduate Research

dehumanization theory by tracking and comparing dehumanizing rhetoric used by all presidential candidates during the 2008, 2012, and 2016 campaigns. Using data hand-collected from all presidential speeches conducted during these periods, including accounting for ad-libbing by Donald Trump, I find that Trump was distinctive in his dehumanization of immigrants and refugees, far surpassing all other candidates. His language surrounding these groups focused heavily on (1) using nonhuman language to describe their actions and migrations, (2) assigning criminality and viciousness to immigrants, (3) repeating stories of the deaths of American citizens by immigrants, (4) saying that immigrants and refugees have values …

Drones On The Rise: Societal Misperceptions Of Small Unmanned Aircraft Systems, Renee Keilman

The Journal of Purdue Undergraduate Research

Throughout the past decade, small unmanned aircraft systems (sUAS) have been on the rise in both the civilian and military sectors. It is forecasted that in the near future they will create thousands of jobs and billions in tax revenue due to their ability to execute difficult and hazardous tasks safely, efficiently, and cost-effectively. However, one current issue with the proliferation of the technology is a shortage of skilled employees due to a lack of education and common negative public misperceptions associated with them.

To investigate this, responses from a mixed-methods survey will be analyzed. Within the survey, questions such …

Propuestas Par (Re)Construir Una Nación: El Teatro De Emilia Pardo Bazán, Margot Versteeg

Purdue Studies in Romance Literatures

Propuestas para (re)construir una nación explores how Emilia Pardo Bazán (1851–1921) imagines and engenders the Spanish nation in her theatrical production staged and/or published between 1898 and 1909. In the aftermath of Spain’s colonial losses, when Spain’s male authors, in a growing mood of collective introspection, directed their attention to the homeland, Pardo Bazán generated a series of theatrical proposals to revitalize the nation. In her plays, she manifests her ideas about Spain’s fin de siècle crisis, reflects on Spain’s place in the international arena (emphasizing the nation’s civilizing mission), critiques the intoxicating power of the so-called golden legend (Spain’s …

Technology And The Positioning Of The Library On Campus: Challenges And Opportunities, John Cox

Proceedings of the IATUL Conferences

Technology has transformed how teaching and research happen, and the strategies and priorities of higher education institutions are continually evolving in response to emerging demands. Positioning itself optimally in a changing organisation is a key challenge for any academic library. The positioning of the library in the institution impacts its status, resources and opportunities. Technology has made effective positioning more challenging, competitive and fluid. This paper examines positioning challenges libraries face on campus and outlines some approaches to advancing their position in the institution.

Digital publishing and communications have moved academic libraries from a position of monopoly for access to …

Both Sides Of The Coin: Supporting Postgraduates And Researchers In Dedicated Spaces At Cput And Stellenbosch University, Dr Michiel Moll, Elizabeth Moll-Willard

Proceedings of the IATUL Conferences

The idea of a space dedicated to supporting research at the university housed within the library is not a new concept. These spaces, often called Research Commons, have been written about widely in literature since 2008. However the impact of these spaces is something that, a decade later, warrants investigation as these spaces have also had to evolve to both meet clients changing needs and to reflect the new trends within libraries.

In South Africa, the Research Commons is a well-known concept within university libraries. Both the Cape Peninsula University of Technology (CPUT) and the Stellenbosch University Libraries offer such …

Applying Fair Principles To Scholarly Publishing Outputs To Improve Open Access Compliance, Trinity Mcnicol, Elena Danilova

Proceedings of the IATUL Conferences

While the FAIR Principles were developed for research data, they can also be aptly applied to other research outputs. Applying FAIR Principles to scholarly publications ensures research can easily be found, accessed, used and re-purposed by others. Using these principles in the context of scholarly publishing helps facilitate access to publications by other researchers and the wider community. The existing services and infrastructure, provided by The University of Queensland Library Scholarly Communication & Repository Services (SCARS) team, supports practical implementation of some of the FAIR Principles in scholarly publishing.

The Scholarly Publishing, Research Outputs & Impact, and UQ eSpace (institutional …

Evaluating Data Management Plans - Are They Good And Are They Effective?, Peter Green, Amy Cairns, Dr. Hollie White

Proceedings of the IATUL Conferences

Since 2014, Curtin University Library has provided support to researchers in using the University’s in-house Data Management Planning (DMP) tool. The tool guides researchers through a series of questions on how they plan to collect, store, secure, and share their research data. Creation of the plan is a prerequisite for staff to obtain ethics approval and file storage. Uptake of the DMP has been excellent over that four years, but are the plans good and are they effective?

In 2018, Curtin University Library chose to collaborate with a Masters by Coursework student, Amy Cairns, to undertake a study to analyse …

Fair, Affordable And Open Access To Knowledge: The Caul Collection And Reporting Of Apc Information Project, Stephen Cramond, Cameron Barnes, Susan Lafferty, Virginia Barbour, Debbie Booth, Karen Brown, Dianne Costello, Kate Croker, Robert O’Connor, Harry Rolf, Tom Ruthven, Sally Scholfield

Proceedings of the IATUL Conferences

Article processing charges (APCs) are fundamental to the business models of many Hybrid and Gold open access (OA) journals. The need to quantify the volume of APC payments paid on behalf of institutional researchers has therefore never been greater. New publishing models will have profound implications for future institutional budgets, and libraries urgently require better information about potential costs and savings.

In 2018, the Council of Australian University Librarians (CAUL) commissioned a project to examine the financial impact of APC payments on universities in Australia and New Zealand. The project aims to develop a methodology for the estimation of APC …

“What’S Up, Doc?”: Selling Digital Literacy To Academics, Marianne Sato, Kathleen Smeaton, Thomas Palmer

Proceedings of the IATUL Conferences

When academics receive emails that start with “Wassup bro?” and students think digital literacy means “computer skills for old people”, how does the library bridge the gap between students and academics? Increasingly, libraries play a pivotal role in supporting learning in this critical space. However, more could be done. Libraries need to advocate for digital literacy as a legitimate capability that should be embedded into the curriculum rather than an optional extra.

In 2018, The University of Queensland Library undertook a project to create digital literacy modules to enable students to develop digital capabilities that would “fit an individual for …

The Push-Pull Of Digital Literacy, Jo Coldwell-Neilson, Kat Cain

Proceedings of the IATUL Conferences

Digital literacy within higher education was originally grounded in Gilster’s (1997) definition that essentially framed it as information literacy using technologies. This has necessarily evolved over the past two decades in conjunction with rapid technological advances. Digital literacy concepts have attempted to match the changing landscape engendered by ubiquitous and ever more available technologies, where cybersecurity and accessibility, multimodal communication channels, and push-pull models of information delivery impact the way we learn, work and play. A dizzying plethora of digital literacy definitions has emerged, with no common understanding of what it means or what skills and capabilities it reflects. Concomitantly, …

Uncovering Digital Literacy And Supporting The Implicit: A Case Study Of Library-Faculty Collaboration, Blair Kelly

Proceedings of the IATUL Conferences

Digital literacy is increasingly seen as an important skill for 21^st century university students. Alongside this, notions of ‘digital natives’ who intuitively or implicitly understand digital literacy persist, despite evidence to the contrary.

In order to better understand how digital literacy is expressed in course curriculum, and therefore provide more effective support to students, Deakin University Library worked with academic staff in the University’s School of Medicine to uncover where digital literacy was assessed across the span of a Master of Optometry degree. This process also revealed to what extent the underpinning digital literacy skills and knowledge needed to …

Amorphous Solid Dispersion Formation Via Solvent Granulation – A Case Study With Ritonavir And Lopinavir, Niraj S. Tirasi, Sonal Bhujbal, Qi Tony Zhou, Lynne Taylor

Department of Industrial and Physical Pharmacy Faculty Publications

Herein, we evaluate the potential of using a simple solvent granulation process to prepare a binary drug amorphous solid dispersion (ASD) containing two anti-HIV drugs, ritonavir and lopinavir. The drugs were granulated onto a mixture of lactose and microcrystalline cellulose, followed by drying to remove the solvent. The resultant granules were characterized and each drug was found to be X-ray amorphous. No crystallization was observed following storage for 1 month under accelerated stability conditions (40 °C and 75% relative humidity). The dissolution behavior of the compacted granules was compared with the marketed formulation. The dissolution rate of ritonavir was found …

The Near Tragedy Of Gemini 8: How Neil Armstrong’S First Space Mission Was Almost His Last, Sam Conkle

Purdue Undergraduate Research Conference

As the space race heated up in the sixties, NASA was scrambling to get ready to put a man on the moon. Though the Apollo program is the one that landed the U.S. on the moon, the Gemini program ensured we had the necessary training and technology to make it to the moon and back. The Gemini 8 mission represented many firsts in NASA’s long journey to the moon. It was the first attempt at docking, an essential and technologically challenging step that is often overlooked in the grand scale of the moon landing. It was also Neil Armstrong’s first …
