Photogrammetric Measurement Of Hardwood Species At A Stand Level Using Rgb Images From Unmanned Aerial Vehicle (Uav), Aishwarya Chandrasekaran
Photogrammetric Measurement Of Hardwood Species At A Stand Level Using Rgb Images From Unmanned Aerial Vehicle (Uav), Aishwarya Chandrasekaran
Purdue GIS Day
Nowadays, for many remote sensing applications, drones are employed for gathering data, as it provides low cost image acquisition with minimal human intervention. Drone remote sensing has an extensive use in forestry for maintaining inventories, mapping canopy structure and monitoring forest fires. Maintaining a Forest inventory database is a crucial task as it is the only means of keeping a record of the trees. This study aims to explore UAV based image acquisition (consumer-grade sensor) and analysis for forest studies using structure from motion technique.The main objective is to derive a methodology for computing tree parameters such as tree height, …
The Transesterification Of Hickory Nuts Into Biodiesel Fuel, Hannah Trauger, Madilynn Dewell, Jahida A. Mendoza
The Transesterification Of Hickory Nuts Into Biodiesel Fuel, Hannah Trauger, Madilynn Dewell, Jahida A. Mendoza
Undergraduate Research Conference
• Biodiesel fuels can be produced from a fat and an alcohol via transesterification
• Hickory nuts have a high fat content (~60 % by weight)
• Can nuts from shagbark hickory (Carya ovata) be used to produce a biodiesel fuel using existing acidcatalyzed transesterification methods?
Extraction And Quantification Of Hydrolyzable Tannins In Acorns From Different Species Of Oak Trees (Quercus Spp.), Sarah Browning, Marshall E. Woodruff
Extraction And Quantification Of Hydrolyzable Tannins In Acorns From Different Species Of Oak Trees (Quercus Spp.), Sarah Browning, Marshall E. Woodruff
Undergraduate Research Conference
Do white-tailed deer (Odocoileus virginianus) prefer to eat certain types of acorns based on tannin content?
Hydrolyzable tannins consist of gallate groups connected via ester linkages to a carbohydrate (D-glucose)
The Prussian Blue method was used to determine hydrolyzable tannin content
Microbial Abundance And The Pattern Of Escherichia Coli Antibiotic Sensitivity And Resistance In Deer Creek And The Potential Impact Of A Veterinarian Hospital’S Input, Sarah Boxer, Tim Gsell
Microbial Abundance And The Pattern Of Escherichia Coli Antibiotic Sensitivity And Resistance In Deer Creek And The Potential Impact Of A Veterinarian Hospital’S Input, Sarah Boxer, Tim Gsell
Research Days
The gram-negative bacteria, E. coli, is an indicator of fecal input for both point and non-point source origin. The veterinarian hospital located on Deer Creek may contribute to high antibiotic levels, which are known to select for resistant strains of bacteria living in impacted waters. The water running north of the veterinarian hospital was considered potentially antibiotic influenced as it was downstream of the site. The origin of the stream and sites upstream from the hospital were considered influent water. Sediments were also collected from these sites to determine if more long term resident E. coli were present with elevated …
Assessment Of Soil Particle Size Distribution Under Four Land Covers In Nachusa Grasslands Of Northern Illinois, Reni Truhtcheva Owikoti, Diana Acosta, Markeia Scruggs, Xiaoyong Chen
Assessment Of Soil Particle Size Distribution Under Four Land Covers In Nachusa Grasslands Of Northern Illinois, Reni Truhtcheva Owikoti, Diana Acosta, Markeia Scruggs, Xiaoyong Chen

Soil particle composition is one of the main physical properties of soil that affects soil fertility and quality. The fractal dimension of soil particle size distribution (PSD) can be used to quantitatively evaluate the particle composition of soils. Land cover change with corresponding management practices is recognized as one important driving force affecting soil PSD alterations. The objective of this project was to determine the changes in soil PSD under four plant covers (Woodland, Wetland, Prairie, and Savannah) at the Nachusa Grasslands in North Illinois. The soil PSD was determined by their settling rates in an aqueous solution using hydrometer. …
