    Evaluating Rubber Aging on Tire Durability: Quantitative Evaluation of Rubber Aging

    Get PDF
    Rubber is considered one of the most important polymers in the world due to its variety of uses. There are many different conditions that can affect the useful life of rubber. The purpose of this research was to determine how the mechanical loading on the rubber may affect the aging of the rubber. The scope of the project was to focus on the rubber used for tire production. The research was limited to focusing only on rubber supplied by industry mentors which was styrene-butadiene rubber. By varying the length of time for testing as well as the temperature of the sample using the eXpert ADMET Mechanical Testing System, it was determined that the longer the sample was exposed to significant cyclic stresses, the more degradation that the rubber sample experienced. The data that was collected was important because it was then used by a graduate student to create a model that best represents the data found during the experimentation. In conclusion, the data was significant because the model being created can help to better understand rubber degradation

    Leptin effects on bone metabolism

    Scales from adult zebrafish, Danio rerio, are an established model for studying osteoblast and osteoclast activity. In this study, scales in a cell culture were used to determine if the hormone leptin has an effect on activity of these bone remodeling scales. Alkaline phosphatase (ALP) and tartrate-resistant acid phosphatase (TRAP) activities of zebrafish scales were measured and compared with and without leptin treatment. There was no statistically significant difference between leptin treatments in terms of ALP and TRAP activity. Differences between TRAP values between days 1 and 2 did look promising although they were not statistically significant. This study could provide an insight into any effect that leptin may have on bone metabolism considering the differences in TRAP activity as previously mentioned. A viable scale assay model, however, was established which can contribute to the understanding of the molecular role of leptin in bone metabolism

    The Corrosion Behavior of AISI 304L Stainless Steel in Simulated Concrete Pore Solution. And A New Marketing Plan for Stainless Steel Rebars.

    The purpose of this project is to study the corrosion behavior of AISI 304L stainless steel, and to present the results for a new marketing strategy for a steel rebar manufacturer. This experiment involved the usage of cyclic potentiodynamic polarization tests to investigate the effect of chlorides on the pitting corrosion behavior of AISI 304L stainless steel in a simulated concrete pore solution with 3.5 wt.% chlorides. The results of this experiment showed that the chlorides caused a large increase in the corrosion current density of AISI 304L stainless steel indicating increased susceptibility to general corrosion and pitting corrosion. The corrosion marketing project resulted in a ready-to-go marketing plan for a rebar manufacturer including a direct mail sales letter, a campaign chart, and instructions for how to test and improve the marketing campaign

    Tort Immunity for Volunteers in Ohio: \u3ci\u3eZivich v. Mentor Soccer Club, Inc.\u3c/i\u3e

    Get PDF
    Commentators have dubbed volunteers the third sector of the American economy, which is otherwise composed of business and government. Various services such as libraries, school boards, scout troops and little league teams depend upon volunteers. However, a series of highly publicized tort actions against volunteers in the 1980\u27s combined with a cycle of increasing insurance premiums and decreasing coverage for volunteers and nonprofit organizations, raised concern within the volunteer community. Over the past several years some jurisdictions afraid of losing volunteer services have made public policy decisions shielding volunteers from liability for their own negligence. This note explores the debate regarding the decision to provide tort immunity for volunteers in the context of the Ohio Supreme Court\u27s opinion in Zivich v. Mentor Soccer Club, Inc

    Every Seed Counts

    Above all else, humans should understand the impact of the decisions they make, before they make them. In specific, the decisions that could harm the environment, whether that is on a large or small scale. Humans create an enormous amount of trash, and for this honors project a campaign was created that emphasizes the importance of being environmentally conscious with paper. Being environmentally conscious can be expressed in a multitude of ways, so the main focus of this project was to create plantable seed paper that people can use and then grow things with after they are finished. This project communicates that even a small decision, like choosing a more environmentally friendly paper, can make the world grow and flourish. The process of creating seed paper, planting, and then growing the plants has been documented in the form of photography and video. These forms of documentation are presented through a 3D gallery, and a websit

    After the Trolls: Patent Litigation as Ex Post Market-Making

    Get PDF
    Patent policy has been dominated lately by efforts to reduce rent-seeking patent troll litigation. As recent reforms begin to take effect, it is timely to consider the more constructive aspects of patent litigation. This Article contends that the lag between product development and patent litigation, which pushes the problem of patent valuation into the ex post (after product development) period, serves just such a positive function. Re-search, development, and product roll-out can all take place first. Then, at a later stage, patent litigation sorts out the relative merits and contributions of the various inventors and competitors who contributed to the new product or technology. In the time between early commercialization and litigation, a good deal of helpful information comes to light about the product and its market. This makes valuation more tractable, especially as compared with the early (ex ante) development period, when uncertainty is high. Litigation also serves as a structured process that promotes party settlement, adding another dimension to its potentially positive role
