    The Cooler Koozie, optimizing thermal insulation for beverage consumption

    Our work aims to develop a new koozie with insulating properties that improve upon the current available commercial options. The hot climate of South Carolina, especially during football season, can heat a consumer\u27s beverage to an unenjoyable temperature in a very short period of time. To recreate these hot conditions in a lab setting, our team designed a hot air circulation box with a temperature controller. Our baseline for improvement was established by testing plain cola cans without koozies, cans with basic foam koozies, and cans with more expensive, name brand koozies. Based on these results, we set out to design a new koozie that would outperform those on the current market. Our design focuses on separating the can from the environment by maximizing captured air space between the two. Air is exploited in our design due to its low thermal conductivity, or ability to reduce heat transfer. The material of construction for our koozie is thin wall, flexible PVC tubing wound around in a spiral manner, and then glued together. We are also investigating different diameter tubing to determine the effect differing amounts air space. These results show that our new design has improved insulating properties compared to commercially available koozies while also being aesthetically pleasing

    ChemE car

    With gas prices rising every day, scientists and engineers are looking to alternative fuel sources to power our vehicles. One project specifically designed to help collegiate engineers work toward an energy solution is the American Institute of Chemical Engineers ChemE Car competition. This competition requires that students build a model car that is powered by an alternative fuel source to gasoline. For the Clemson ChemE Car team, we are building a car that is powered by a silver oxide - zinc battery. Additionally, our stopping mechanism is an iodine clock, in which a delayed light sensor stops the car once the iodine reaction darkens. We will be testing our car at the Southern regional conference in Puerto Rico over Spring Break, and we will present our competition results

    The Collaborative Design Virtual Environment (CDVE)

    In any construction project, designers are responsible to propose and develop designs based on the owner’s requirement. Designs are primarily produced and presented in the form of 2D CAD drawings that can later be used by the builder to erect the facility. Nowadays, as technologies improve, the complexity of building designs also increases. Designs are produced by various designers residing either within the same firm, outsourced, or through collaboration of many design firms. Due to this nature of production of designs, effective communication and collaboration among individuals involved are important. Current design collaboration tools are mostly in non real time fashion and the designs are not in 3D. This video presents an application currently under development to support real-time design collaboration in a virtual environment (VE). This application is called the ‘Collaborative Design Virtual Environment’ or ‘CDVE’. The CDVE support many collaborative real time 3D interactions such as moving, rotating, scaling, hiding, duplicate 3D object that exist in the VE

    Major surgery in an osteosarcoma patient refusing blood transfusion: case report

    Get PDF
    We describe an unusual case of osteosarcoma in a Jehovah's Witness patient who underwent chemotherapy and major surgery without the need for blood transfusion. This 16-year-old girl presented with osteosarcoma of the right proximal tibia requiring proximal tibia resection, followed by endoprosthesis replacement. She was successfully treated with neoadjuvant chemotherapy and surgery with the support of haematinics, granulocyte colony-stimulating factor, recombinant erythropoietin and intraoperative normovolaemic haemodilution. This case illustrates the importance of maintaining effective, open communication and exploring acceptable therapeutic alternative in the management of these patients, whilst still respecting their beliefs

    An Examination of Not-For-Profit Stakeholder Networks for Relationship Management: A Small-Scale Analysis on Social Media

    Get PDF
    Using a small-scale descriptive network analysis approach, this study highlights the importance of stakeholder networks for identifying valuable stakeholders and the management of existing stakeholders in the context of mental health not-for-profit services. We extract network data from the social media brand pages of three health service organizations from the U.S., U.K., and Australia, to visually map networks of 579 social media brand pages (represented by nodes), connected by 5,600 edges. This network data is analyzed using a collection of popular graph analysis techniques to assess the differences in the way each of the service organizations manage stakeholder networks. We also compare node meta-information against basic topology measures to emphasize the importance of effectively managing relationships with stakeholders who have large external audiences. Implications and future research directions are also discussed
