How To Impress: Coordinating A Large Video Data Set For A Collaborative Project, Noah-Kee Marks, Rita Dawod
DePaul Discoveries
Though many different research methods involve mass quantities of video/audio data, there is little discussion of best practices for organization, especially when the research is collaborative. The guidelines we provide here were created while conducting educational research on the IMPRESS project, an integrated metacognitive program for at risk STEM majors at Rochester Institute of Technology (RIT). Our hope is to encourage large-scale, collaborative research of qualitative video data by using our project as an example and providing enough information for readers to make a judgment on the efficacy of this process for their own projects.
Wavelet Packet Analysis Of Amino Acid Chain Sequences In The Proteins Of Mesophile And Thermophile Bacteria, John B. Linehan
Wavelet Packet Analysis Of Amino Acid Chain Sequences In The Proteins Of Mesophile And Thermophile Bacteria, John B. Linehan
DePaul Discoveries
In this project, proteins from mesophile and thermophile bacteria with similar functions are compared. Initially it is assumed that the differences between these two bacteria are substantial to be recognized in the amino acid sequences of their proteins. These differences would then lead to the creation of a statistical measure, which would allow the classification of a protein to its corresponding bacteria. By assigning hydrophobicity values from three well-known scales, a discrete numeric signal is produced for each protein, which is analyzed using wavelet packets. The result of this method indicates that the overall hydrophobic tendencies of these two bacteria’s …

Using data archives containing radial-velocity and light intensity information for stars, the DePaul Astrophysics Working Group created MATLAB programs to read and analyze the data in hopes of detecting extrasolar planets. The codes were able to successfully create graphs and obtain orbital periods for potential planets which matched published results. Additional tests were then researched to be used in the future as to confirm new planets.
Greenhouse Gas Flux Response To Harvest Of Typha X Glauca In A Great Lakes Coastal Wetland, Olivia Johnson
Greenhouse Gas Flux Response To Harvest Of Typha X Glauca In A Great Lakes Coastal Wetland, Olivia Johnson
DePaul Discoveries
Although harvesting invasive species can promote biodiversity during wetlands restoration, there is little known about this mechanical treatment’s impacts on greenhouse gas flux, a significant biosphere-atmosphere interaction. We quantified greenhouse gas flux response to experimental harvest of invasive cattail (Typha x glauca) at Cheboygan Marsh in Northeastern Michigan during the 2015 growing season. During each sampling campaign (July 15, July 31, August 12) we collected gas samples from static PVC chambers at 6 harvest and adjacent Typha control plots. Using gas chromatograph analysis, we found no significant difference in CH4 or CO2 flux between harvest and control plots on any …
Quantifying Greenhouse Gas Flux Of Restored Vs. Unrestored Wetlands: A Case Study At Prairie Wolf Slough, Matthew Connors, Beth Lawrence
Quantifying Greenhouse Gas Flux Of Restored Vs. Unrestored Wetlands: A Case Study At Prairie Wolf Slough, Matthew Connors, Beth Lawrence
DePaul Discoveries
Wetlands provide ecological services such as cleansing the water supply, sequestering carbon, and providing habitat for wildlife, however wetland restoration often alters the greenhouse gas flux of the site. Our study aims to investigate the effects of wetland restoration on greenhouse gas flux at Prairie Wolf Slough. We did this by comparing greenhouse gas flux on matching hydric soil series from the restored wetland with an adjacent abandoned agricultural field. We measured known controls of greenhouse gas flux such as soil moisture and soil temperature. We found that there was no detectable methane and nitrous oxide flux at either site, …
Combinatory Effect Of Changing Co2, Temperature, And Long-Term Growth Temperature On Isoprene Emissions, Michael Cole
Combinatory Effect Of Changing Co2, Temperature, And Long-Term Growth Temperature On Isoprene Emissions, Michael Cole
DePaul Discoveries
Isoprene, the most abundant hydrocarbon in the atmosphere, plays a significant role in atmospheric chemistry. Its reactions with NOx lead to the formation of ozone in the lower troposphere, which is harmful to plants and detrimental to human health. As air temperatures and CO2 concentrations increase with climate change, it is uncertain how isoprene emissions from plants will respond. We hypothesized that isoprene emissions will increase with the combination of increasing temperature and CO2 concentrations. We predict that oaks grown at a higher temperature will exhibit an increase in isoprene emissions with combined short-term increases in temperature …
Implications Of Manipulations Of Soil Quality On The Growth Of European Buckthorn (Rhamnus Cathartica) In A Greenhouse, Sam L. Pepper, Liam Heneghan
Implications Of Manipulations Of Soil Quality On The Growth Of European Buckthorn (Rhamnus Cathartica) In A Greenhouse, Sam L. Pepper, Liam Heneghan
DePaul Discoveries
European buckthorn (Rhamnus cathartica L.) is an invasive shrub that is capable of changing the nitrogen content of a soil through the deposition of its nitrogen rich leaf litter. This change creates conditions that may favor recolonizing by buckthorn and negatively affect the growth of native plants. In this greenhouse experiment, we examined the effect of altering soil quality by adding mulch comprised of buckthorn wood on above and belowground biomass, stem length and leaf production of buckthorn saplings. We found that buckthorn saplings planted in buckthorn mulch had reduced stem length and leaf production compared to growth in …
Comparison Of Soil Phosphorus Concentration In Farm Restored And Reference Wetlands In Lake County, Il, Catherine L. Pease
Comparison Of Soil Phosphorus Concentration In Farm Restored And Reference Wetlands In Lake County, Il, Catherine L. Pease
DePaul Discoveries
The soil in the Midwest is fertile for agriculture use and therefore a lot of the wetlands have been turned into farmland. Wetlands can act as a sink for excess nutrients such as phosphorus. In part due to their value for nutrient storage, restoration of wetlands has become more frequent, including restoration of wetlands on former farmland. I am interested in phosphorus and the potential of wetlands to either store or release phosphorus. I compared differences in soil reactive phosphorus of restored and reference wetlands. This study compares Prairie Wolf Slough (PWS), a restored wetland, to two reference wetlands, both …
Decomposition Of Horse Manure (As A Surrogate For Human Feces) In Three Soil Media And The Implications Of Manure Leachate For The Germination Of Radish Seeds, Edwin J. Castaneda, Caitlin Vaughn
Decomposition Of Horse Manure (As A Surrogate For Human Feces) In Three Soil Media And The Implications Of Manure Leachate For The Germination Of Radish Seeds, Edwin J. Castaneda, Caitlin Vaughn
DePaul Discoveries
In this microcosm study we examined the decomposition of horse manure in three substrates: potting soil, wood mulch, and sand. Microcosms consisted of a sample of horse manure placed in a small leachable chamber, containing one of the three substrates. Mulch promoted the greatest mass loss. Leachate collected by irrigating each microcosm with distilled water was used to germinate radish seeds. Only the leachate from microcosms in which manure decomposed in potting soil promoted greater radish radicle growth compared to the controls in which no manure was placed. The implications of these results for the design of a soil-based decomposing …
Host-Parasite Relationships Between The Copepod Naobranchia Lizae And Its Host (Striped Mullet, Mugil Cephalus): A Description Of Morphological Development, Sara R. Teemer
DePaul Discoveries
The parasitic copepod, Naobranchia lizae, is often found within the gill arches of the striped mullet, Mugil cephalus, in the Charleston Harbor Estuarine System of South Carolina. The parasite is relatively common, but little is known about its early stages of development. In order to describe the developmental stages and pattern of morphological development, 221 female N. lizae that were collected between February 2002 and May 2003 were used. Using variation in morphological characters (maxilla, trunk), these parasites were assigned to developmental stages (juvenile, subadult, adult). A small number of the males (three ‘dwarf’ males) were also found …
The Correlation Between Basal Isoprene Emissions And Climate Of The Native Range Across Oak Species, Mary J. Babiez
The Correlation Between Basal Isoprene Emissions And Climate Of The Native Range Across Oak Species, Mary J. Babiez
DePaul Discoveries
Isoprene is a biogenic volatile organic compound that is emitted by various plant species and plays an important role in the chemistry of the atmosphere. When it reacts with pollutants in the air, such as nitrogen oxides, the precursor to ozone (O3) is formed. In this experiment, we measured leaf emissions from 20 different oak species at the Morton Arboretum (Lisle, Illinois). The aim was to better understand differences in isoprene emissions across oak species. Since emissions have been found to protect leaves against brief periods of heat stress, we hypothesized that oaks native to areas with greater …
Understanding How Plant Diversity Impacts Wildlife Species Richness In Chicago Area Forested Greenspaces, Katie Kamba
Understanding How Plant Diversity Impacts Wildlife Species Richness In Chicago Area Forested Greenspaces, Katie Kamba
DePaul Discoveries
Factors related to urbanization have altered the pre-settlement landscape of Chicago from native prairie and woodland, to one dominated by non-native plant species. This study examined how the plant community influences urban wildlife by investigating how vegetation structure (as measured by three indices) relates to the wildlife richness of 24 forested sites in the Chicago region. We found negative relationships between both Floristic Quality Index (FQI) and native plant diversity with wildlife richness. We propose that the generalist mammal species that were detected using the camera trap method do not require high quality forested habitat and seem to prefer lower …
