Wind power represents one of the most promising sources of renewable energy and improvements to wind turbine design and control can have a significant impact on energy sustainability. This proposal is about a new design for efficient VAWT. Typically, VAWT power output is generated from the difference between the forces on the forward and backward facing blades to the wind direction. That reduces their efficiency as compared to the Horizontal Axis Wind Turbine (HAWT). The current innovation, eliminates the forces on the backward facing blades using dynamic blades which improve their efficiency to be comparablewith the HAWT.
In addition, the turbine is fitted with aerodynamic brakes that safely stop the turbine at low and high wind speeds. This safety feature does not exist in any Vertical Axis Wind Turbine in the market. The innovation received the Accelerator to Commercialization award in 2014 from the state of Ohio and University of Cincinnati. Several small size prototypes were builtwhich validated the concept.
VAWTs are capable of catching wind from all directions which avoid the need for yaw mechanisms, rudders or downwind coning. The electric generators can be positioned near the ground and are easily accessible for maintenance. The new invention will revolutionize thewind turbines andwind farms technology by improving the VAWT efficiency and safety.

Abstract: In 2018, the University of Cincinnati Libraries’ Research & Data Services (RDS) unit unveiled a new Visualization Laboratory (Viz Lab) and expanded service model including data visualization/data analysis. The RDS unit has its roots in STEMM and currently includes informationists, librarians and technical consultants who engages with researchers across all disciplines. The Viz Lab and its associated services are the culmination of several years of planning and implementation. This poster will share lessons learned and good practices with our visualization space and service planning, including considerations for space design, service and training models, staffing and assessment. In addition, this poster will describe the early impact of our efforts, as seen through consultation logs, trainings and campus outreach, space usage and grants activity. We will also reveal some future directions for RDS, including plans to increase integration of the Viz Lab and data visualization/data analysis services into the university’s teaching and research missions.

This Poster describes a collaborative research project between the Culley and Tepe labs in the UC Department of Biology and UC Libraries Digital Scholarship Center presented at the 2017 UC Data Day ( https://libapps.libraries.uc.edu/blogs/dataday/past-data-days/). The project explores publication patterns of research involving hotspot areas of biodiversity and if researchers from developing countries which tend to have most of the biodiversity hotspots, are adequately represented as authors in the scientific literature indexed in Scopus (TM-Elsevier), JSTOR, and PubMed.
The Retrosplenial Cortex (RSC) has a persistent role in the establishment of spatial and contextual memory, with also the connections between visuo-spatial association cortices. The RSC’s ability to form afferent and efferent connections with the Parahippocampal areas of the brain allow it to be another prime location in the brains of both rodents and humans where multiple cues are linked together in memory formation, storage and retrieval of Long Term Memories. Due to the high nature of memory formation and retrieval, the RSC has become a section of the brain that in recent years has been more heavily focused on for the research of Alzheimer’s and Dementia. The RSC has not been examined fully in previous studies with examination of the expression of the apolipoprotein E (APOE) gene along with other genetic and regulatory factors. There are 3 major alleles of the APOE gene (APOE2, APOE3, and APOE4), with APOE4 having the greatest risk for AD. In this research, I identify the relative connection between DEK the proto-oncogene and APOE3 and APOE4 in a rodent model, looking specifically at the RSC and how it affects spatial memory with an induced model of chronic stress.

A major goal of higher education is to help students choose purposeful pathways through college as they acquire skills that support them in becoming self-regulated and lifelong learners. This poster describes the successful implementation of two practices that foster self-regulated learning, a before- and after-course case study used to assess course knowledge and goal setting, in a fully online teacher education course. In addition to describing the practices, the poster includes a thematic analysis of the data from open-ended student responses to the assignment. Participants are invited to discuss the implications of this work and its potential applications in their classrooms.
After interacting with others at this poster, you will be able to: (a) describe two practices for developing self-regulated learners, (b) identify lessons learned from the implementation of these practices in a fully online teacher education course, and (c) apply these practices to one of your own courses.
The purpose of this project is to consider and evaluate the economic attractiveness of a process producing 250,000 lb/h of acetic acid by the selective carbonylation of methanol via carbon monoxide with the use of an iridium tri-iodide catalyst. Initial cost estimates of this process will be completed prior to the completed rigorous design to ensure the process is economically viable and meets product specifications. A full cost analysis will then be made on the initial design to further verify the process will meet product specifications and is economically attractive to the business. A recommendation to continue investigating will be made based on the analysis of the investment cost and annual operating costs of this reaction/separation system.
An economic analysis was performed on the selected design. The total capital cost for this project is $145 million, with a yearly utility and incremental cost of $62 million and $90 million, respectively. The required ten-year return on investment was found to be 15%, when the Acetic Acid is sold at a price of $437 /ton. When the Acetic Acid is sold at $745/ton (achieves 15% 1-year ROI), an ROI of 547% is achieved for a 10-year period. In order to achieve a five-year ROI of 15%, the selling price of Acetic Acid is only increased to roughly $455/ton.
