    The transportation industry touches every facet of business: research and development, final mile services, raw material procurement, even technology innovation and application design. Without transportation of goods, people, and services, each business as we know would fall apart. The greater supply chain itself relies heavily on the presence and precision of transportation to create value for each specific company’s operations. Beginning in the summer of 2022, I have had the privilege of interning at J.B. Hunt Transport, Inc., one of the world’s largest logistics and transportation companies, which has opened my eyes to the sheer impact of transportation on each level of business operation. In my time as an Intermodal Appointment Intern with J.B. Hunt, I have gained experiential knowledge of the transportation industry overall and specifically intermodal rail operations by working alongside rail operations professionals and working with customers to ensure On Time Delivery and drive value for each organization

    The European Experience: A Multi-Perspective History of Modern Europe, 1500–2000

    Get PDF
    The European Experience brings together the expertise of nearly a hundred historians from eight European universities to internationalise and diversify the study of modern European history, exploring a grand sweep of time from 1500 to 2000. Offering a valuable corrective to the Anglocentric narratives of previous English-language textbooks, scholars from all over Europe have pooled their knowledge on comparative themes such as identities, cultural encounters, power and citizenship, and economic development to reflect the complexity and heterogeneous nature of the European experience. Rather than another grand narrative, the international author teams offer a multifaceted and rich perspective on the history of the continent of the past 500 years. Each major theme is dissected through three chronological sub-chapters, revealing how major social, political and historical trends manifested themselves in different European settings during the early modern (1500–1800), modern (1800–1900) and contemporary period (1900–2000). This resource is of utmost relevance to today’s history students in the light of ongoing internationalisation strategies for higher education curricula, as it delivers one of the first multi-perspective and truly ‘European’ analyses of the continent’s past. Beyond the provision of historical content, this textbook equips students with the intellectual tools to interrogate prevailing accounts of European history, and enables them to seek out additional perspectives in a bid to further enrich the discipline

    Evaluations of FRP Composite Coupons Under Impact and Puncture Lekhnath Bhandari Railroad tank cars are the main mode of transportation for carrying flammable liquids and other hazardous materials, in any mode of ground transportation system. These tank cars, if punctured during derailments may explode releasing large amounts of hazardous materials and posing serious threats to human life and leading to economic losses. To minimize such catastrophes, in 2015, United States Department of Transportation (USDOT) proposed to improve the thermal and puncture performances of these tank cars and introduced two new design specifications: DOT-117 and DOT-117R. Tank cars with 9/16 inches AAR TC 128 steel inner tank body, a ½-inch thermal protection system and an 11-gauge A1011 outer steel jacket along with other safety enhancements such as protected top fittings, fully protected head shield and bottom outlet valve are new non-pressurized DOT-117 tank cars. Tank cars that have been retrofitted to satisfy the DOT-117 specifications, to include a jacket and head shield are of the DOT-117R class. Using the best quality thicker steel can improve the impact and puncture resistance of tank cars but reduces the car’s payload because of significant self-weight increase. Moreover, it increases fuel consumption and transportation costs, which are not desirable for the stakeholders. West Virginia University Constructed Facilities Center (WVU-CFC) proposed the multifunctional composite jacket containing sacrificial layers and intumescent coating to be wrapped over existing steel tank cars, providing a cost-effective retrofit solution. WVU-CFC came up with a combination of materials and manufacturing technique for the polymer composite jacket. Making use of these materials and manufacturing techniques, composite coupon specimens were manufactured and tested under static and dynamic loads as per the ASTM standards to determine their impact and puncture behaviors. Different parameters associated with the puncture and impact behavior were evaluated. These parameters are fabric combinations and stacking sequences, thru-thickness stitching of fabric layers, resin types, core materials, and increase in number of fabric layers in composite jacket. These parameters were studied and modified based on the results obtained from static and dynamic tests on coupon specimens to obtain the most efficient composite jacket. The best performing composite coupons were then tested in the presence of foam and steel substrate under static puncture and dynamic impact loads to determine their puncture and impact behaviors in a real tank car scenario. These test results were then compared with DOT-117 tank cars test results to confirm the superior puncture and impact performances of the composite jacket manufactured by CFC-WVU. It was observed that the composite jacket manufactured by CFC-WVU, being 4.3 times lighter than DOT-117 outer steel shell, is about 1.9 times better (1463 ft. lb./lb. vs 786 ft. lb./lb.) in terms of specific energy absorption under dynamic impact loading. Moreover, the combination of composite jacket, foam, and steel, at composite failure, is about 2.1 times better than DOT 117 outer steel shell (1608 ft. lb./lb. vs 786 ft. lb./lb.) in terms of specific energy absorption under dynamic loading. If the combination of steel, foam and composite jacket could be tested up to steel failure, the ratio would be much higher than 2.1

    For Life and Longing: How the People of Eastern Anatolia and Transcaucasia Navigated the Interwar, As Witnessed by the 1919 American Military Mission to Armenia

    Get PDF
    In August 1919, fifty-three American service members left behind the war-torn Western Front and embarked on an investigative mission to former Ottoman territory where, on orders from President Wilson, they were to assess the potential cost of committing United States’ resources to restore governance in Anatolia. As they ventured deep into the interior, the American Military Mission to Armenia encountered Turks, Armenians, Kurds, and others, all vying for legitimacy amid lingering devastation and uncertainty. By recovering the mission’s records, my goal is to correct homogenous characterizations of the region by introducing people who interacted with the mission members. In each town and with each group, we see local needs and desires, unsung narratives different from existing versions of history that survived this tumultuous period. Though the United States Congress eventually voted against intervention and Allied interest in Anatolia waned as the Turkish Nationalists seized power, I have found alternative courses that local groups longed for. In 1919, people in the Ottoman space believed that American mission members could help them as they competed for power, sought external recognition of their trials, and simply struggled to survive. These stories have persisted for over a century and continue to elicit intense emotion among local groups. This fleeting opportunity to shape the future of Eastern Anatolia and Transcaucasia in the interwar space of 1919 has been captured by the mission’s records. My project focuses on understanding local voices and the divergent paths they imagined, perspectives that cannot be ignored during similar moments when destiny is at stake.Doctor of Philosoph

    Eden is on Puget Sound : Folk Music Stories in the Northwest

    Get PDF
    During the folk music revival period, roughly the early 1940s to the late 1960s, folk musicians, music collectors, and folk music insiders forged a connection between American folk music, the past, and ideas of cultural authenticity. In this national context of renewed interest in folk music traditions, folk music communities across the United States cropped up. This thesis analyzes the ideologies and activities of Pacific Northwest folk music communities in the 20th century, with a particular focus during and after the revival period. Typical narratives of the American folk music revival terminate at the end of the 1960s; however, in Washington state there continued to be vibrant and evolving communities based around folk music practice well into the 1980s. This thesis examines the use of folk music in the Northwest to reveal constructions of place and regional identity. Through an analysis of specific Washington state folk songs, communities like the Seattle Folklore Society and the Whatcom County Homemade Music Society, and the development of folk music projects forged in collaboration between folk musicians and state and national government, this thesis provides a deeper understanding to the function of folk music in the Pacific Northwest, the limits and potential of ideology, and the unstable character of the stories we tell about ourselves

    Train post-derailment behaviours and containment methods: a review

    Get PDF
    Railway accidents, particularly serious derailments, can lead to catastrophic consequences. Therefore, it is essential to prevent derailment escalation to reduce the likelihood of severe derailments. Train post-derailment behaviours and containment methods play a critical role in preventing derailment escalation and providing passive safety protection and accident prevention in the event of a derailment. However, despite the increasing attention on this field from academia and industry in recent years, there is a lack of systematic exploration and summarization of emerging applications and containment methods in train post-derailment research. For this reason, this paper presents a comprehensive review of existing studies on train post-derailment behaviours, encompassing various topics such as post-derailment contact–impact models, dynamic modelling and simulation techniques, and the primary factors influencing post-derailment behaviours. Significantly, this review introduces and elucidates substitute guidance mechanisms (SGMs), which serve as railway-specific passive safety protection and accident prevention measures. The various types of SGMs are depicted, and their ongoing developments and applications are explored in depth. The review additionally points out several unresolved challenges including the adverse effects of SGMs, and proposes future research directions to advance the theoretical understanding and practical application of train post-derailment behaviours and containment methods. This review seeks to be a valuable reference for railway industry professionals in preventing catastrophic derailment consequences through post-derailment containment methods

    Bibb Balancing: Regulatory Mismatches Under the Dormant Commerce Clause

    Get PDF
    Courts and commentators have long understood dormant Commerce Clause doctrine to contain two types of cases: discrimination and undue burdens. This Article argues for a more nuanced understanding that divides undue burdens into single-state burdens—which arise from the application of a single state’s law alone—and mismatch burdens, which arise from legal diversity. Although the Supreme Court purports to apply Pike balancing in all undue-burden cases, we show that the Court’s approach in mismatch cases differs substantially. Specifically, unlike in single-state cases, balancing in mismatch cases involves an implicit and potentially problematic comparison by the Court between the challenged state’s regulation and those of other states. We label analysis in mismatch cases “Bibb balancing,” after the famous mudflaps case, and we show that mismatch cases present the Court with a more challenging set of issues than do other types of dormant Commerce Clause cases. Despite the criticisms that attach to Bibb balancing, we recognize that failing to restrain regulatory mismatches would threaten the smooth functioning of the national marketplace and undercut important federalism values. Thus, in addition to clarifying the doctrine and acknowledging the drawbacks of Bibb balancing, this Article provides advice for achieving more consistent and defensible results in mismatch cases
