Designing and Developing a Commercial Delivery Drone
No full textUnmanned aerial vehicles (UAVs) are a technology quickly emerging as a solution in numerous sectors including disaster relief, crop dusting, border enforcement, and commercial delivery. While delivery UAVs are already in use, a compact vehicle capable of delivery in an urban environment is not yet a reality. In this thesis I consider the flight efficiency and performance, propulsion systems, and vehicle configuration requirements needed to build a compact delivery drone capable of carrying a 1-pound payload within a 1-mile radius
Student-Faculty Collaborative Research Grant Report
No full textI proposed to use graphene as a biosensor to observe the life processes of yeast cells in situ. When yeast is maintained in an anaerobic environment, it produces fermentation, and delicious wine. However, when oxygen is present, yeast undergoes a preferable (for it) electron transport pathway, the byproduct of which can ruin wine. By growing yeast on graphene biosensors, we hope to be able to detect these changes

crisscrossing Science Episode 105: Teaching Evolution
No full textIn this episode, Mike Crosser (professor of physics at Linfield University) and Chad Tillberg (professor of biology at Linfield University) interview their colleague Dr. John Syring (professor of biology at Linfield University), who is an evolutionary biologist. The three professors get into the hows and whys of teaching evolution
Linfield Bound
Get PDFFrom generation to generation, Wildcat values link us. Linfield\u27s director of communications and marketing, Scott Bernard Nelson (class of 1994), pens an essay explaining how decisions sometimes take us completely by surprise
crisscrossing Science Episode 112: Room Temperature Superconductivity
No full textIn this episode, Mike Crosser (professor of physics at Linfield University) updates Chad Tillberg (professor of biology at Linfield University) on a discovery of room temperature superconductors. Most superconductors require ultra-low temperatures in order to show their effects. However, researchers recently discovered a way to remove electrical resistance in a sample as high as 57 degrees Fahrenheit
Separation, Quantification, and Visualization of DNA
Get PDFMitochondria are involved in numerous essential cellular pathways. Mitochondria contain their own DNA genome (mtDNA), which is distinct from nuclear DNA. A major goal of our research is to understand the mitochondrial genome as a whole as well as how mitochondrial transcription is affected through changes in the proteins involved in regulation. The direct output of mitochondrial transcription is mitochondrial RNA (mtRNA), so separation and quantification of this mtRNA would be highly beneficial to this understanding. Ion-pair reversed-phase high performance liquid chromatography (IP RP HPLC) has been reported to be an effective way to analyze DNA and RNA oligonucleotides. IP RP HPLC can analyze oligonucleotide samples in less time than analysis by agarose gel electrophoresis followed by ethidium bromide detection or labelling which both take significantly more time. We report a novel IP RP HPLC method which separated ssDNA samples of 54 nt and 58 nt with good resolution. This method also quantified ssDNA samples of 54 nt and 58 nt upwards of 5000 ng. This method is further being optimized to separate similarly sized RNA samples. The ultimate goal is to separate mixtures of nucleotides generated from in vitro mitochondrial transcription reactions. We also report a method for imaging DNA molecules immobilized on mica in air using atomic force microscopy (AFM) as another method to ultimately analyze protein-mtDNA interactions
