take those concepts and relate them to real-world applications. If students cannot grasp the material on a small scale, it is not likely that they will be able to comprehend the actual processes surrounding fluid dynamics that happen on our planet. Our research has been dedicated to figuring out methods in which we can visually connect images from the tank to images of oceanic and atmospheric processes on Earth. We have taken videos of several introductory activities with the goal of improving the visual quality of each experiment. Improvements that we have made include new equipment and designs for the tank that will allow experiments to be carried out with minimal interruption and error. We are currently experimenting with fluorescent dye and black light to eliminate shadowing in the videos of our experiments. Also, we have discovered ways to make the visual aspect of tank activities more similar to images of Earth. This allows for abstract ideas about fluid dynamics replicated by the tank to be made concrete, thereby facilitating the students understanding of real-world processes. Our hope is that students will gain a stronger understanding of the subject matter by relating a small-scale visual reference to the large-scale processes that are actually at work on our planet. Presentation Type and Session: Poster VIII The Snow Season That Wasn’t Michael Borrelli, Geography Faculty Mentor: Professor Stephen Vermette, Geography and Planning On the Buffalo State campus, snow spotting should be a whirlwind of activity of running out between classes to measure different spots to get an average snowfall depth or jumping snow drifts to get to that perfect last patch of untouched snow in the courtyard. This season was anything but exciting from a snow standpoint. My ruler and I were underworked this season with only 27 inches of measured fallen snow, which is well below the campus average. With only one synoptic snow event that brought over four inches of snow to the campus, this winter was not your typical Buffalo State winter. Buffalo’s snow season, as defined by the National Weather Service, occurs between November 1st and April 30th. Buffalo State College’s snow season is moderated a bit because of our proximity to Lake Erie. This snow season was warmer than average, with slightly above average precipitation amounts that fell mostly as rain. Compared to past winters, this was the least snowiest winter on Buffalo State Campus since Snow Spotter records were started in the 1999 - 2000 snow season. This snow season also saw the Buffalo State campus relatively unaffected by any large-scale lake effect event. Only one such storm dropped snow on campus and that was “Eloene” that gave 2 inches on Jan 13-14, 2012. Presentation Type and Session: Poster II Physical Geography, Sciences, and Mathematics Spatial Analysis of Sex Crimes Within the City of Buffalo, New York Jennifer O’Neil, Criminal Justice Faculty Mentor: Professor Tao Tang, Geography and Planning The research focuses on the spatial analysis of sex crimes within the City of Buffalo, NY during the years of 2009 and 2010. The analysis highlights possible key correlations between rapes and factors such as known/unknown relationships between victim and suspect, frequency during fall/winter and spring/summer months, distance from municipal housing units and occurrences within proximity of colleges and universities. Data was obtained through Buffalo Police Department incident reports and analysis was conducted by using Geographic Information Systems (GIS). The study concluded that 72% of rapes involved a known relationship between victim and suspect and 61% occurred during the spring/ summer months. Additionally, 29% of rapes occurred within 0.5 miles of municipal housing units and 41% occurred within 1 mile of colleges and universities. Keywords: rapes, alcohol, juveniles, narcotics, municipal housing authority, spatial distribution Presentation Type and Session: Poster I Structure Function Analysis of the Innexin Shaking-B: Role of the N-Terminus In Establishing Rectifying Gap Junctions William Marks, Biology Faculty Mentor: Professor Martha Skerrett, Biology Innexins are invertebrate proteins that form gap junctions, dense arrays of intercellular channels that allow for the direct sharing of ions and small matabolites between cells. The Shaking B innexins are expressed in the central nervous system of Drosophila melanogaster, where they form a rectifying electrical synapse that allows impulses to travel unidirectionally from the brain to the flight muscles. These rectifying junctions play an integral role in the visually mediated escape reflex of arthropods. In order to understand electrical rectification at a molecular level, site-directed mutagenesis was used to alter the constituent proteins. The amino terminal domain of the innexin Shaking B (lethal) was replaced with that of Shaking B (N+16), the proteins were expressed exogenously, cells were paired overnight, and gap junctions were analyzed using dual cell two electrode voltage clamp techniques. Electrophysiological analysis confirmed that properties of rectification are determined largely by the amino terminal domain of ShakB innexins.

104 Physical Geography, Sciences, and Mathematics Studies of Growth and Optical Properties of LuFe2O4 Thin Films Aaron Sprow, Physics and Anthony Delmont, Physics Faculty Mentor: Professor Ram Rai, Physics Our research was primarily concerned with the preparation method and optical characterization of epitaxial lutetium iron oxide LuFe2O4 (LFO) thin films. Growth parameters considered included pellet composition, pellet size, evaporation method, substrate composition, and substrate temperature. Successful results were achieved using stoichiometric proportions of Fe2O3 and Lu2O3 that were ground and pressed into approximately 3 gram per pellet, followed by sintering at 1100 0C. The LFO thin film deposition process started with heating the target pellet by an electron beam for roughly an hour, and then slowly evaporating LFO onto (001) LNO, (111) YSZ, (001) sapphire, and (001) quartz substrates at 750 0C, to a thickness of about 300 nm. We measured transmittance and absorbance on the annealed LFO thin films as a function of wavelength, varying from ultra-violet to near infrared wavelengths (200 – 3000 nm). The optical data demonstrate that LFO is an insulator having a well-defined energy gap and several electronic excitations associated with charge transfer transitions. Estimating from the absorption spectra, the energy band gap was found to be about 2.20 eV at 300K. Presentation Type and Session: Poster VI Studies of the Gap Junction Protein Connexin31 Orlando McEwan, BIO 498: Biology Honors Faculty Mentor: Professor Martha Skerrett, Biology Gap junction channels allow direct communication between adjacent cells. Gap junction channels of chordates are composed of connexins, with six connexins required to create a half-channel, also known as a connexon or hemichannel in each adjacent cell. An intercellular gap junction channel is created when a connexon from one cell docks with a connexon from an adjacent cell. In humans, twenty connexins are expressed in specific but overlapping patterns to create gap junctions with a diverse set of properties. Connexin31 (Cx31) is expressed in the auditory system and skin of humans where it is expected to interact heterotypically and heteromerically with several other connexins. Mutations in Cx31 are associated with multiple human diseases including deafness and erythrokeratodermia variabilis (EKV). The mutation Cx31L34P causes EKV and this study was designed to further assess the characteristics of this mutation at a molecular level. The amino acid leucine at position 34, was modified to tryptophan (Cx31 L34W) using site-directed mutagenesis. Other studies suggest that the amino acid at position 34 interacts closely with another protein domain and we aimed to confirm this for Cx31 by substituting tryptophan for the native leucine at position 34. Presentation Type and Session: Poster VI Surface Water Quality and Risk Analysis In a Peri-Urban Area, Thailand Jameieka Price, Masters Multidisciplinary Studies Faculty Mentor: Professor Kim Irvine, Geography and Planning The Rangsit Canal, Pathum Thani, Thailand, receives runoff and contaminant inputs from urban and agricultural activities. Water quality in a section of the canal was examined by comparing sample results with Thailand’s water quality standards, the approximate delta method to characterize system metabolism, and a microbial risk analysis to assess potential for waterborne infections. Dissolved oxygen and BOD levels did not meet Thailand’s Class 3 standards. Continuous, automated monitoring of dissolved oxygen revealed a pronounced diel trend driven by photosynthesis during the day and respiration at night. Compared to many water bodies, however, the primary production of the canal was low and can be classified as heterotrophic. Based on a microbial risk assesment and considering infection risk standards, E.coli levels measured in the local sewer system (10^6 CFU/100 mL) and canal (10^4 CFU/100 mL) produced unacceptably high risk for activities that included swimming, vegetable farming, fishing, and sewer pump station operations. E.coli in piped water to an informal community on the canal was 0 CFU/100 mL in half the samples. The highest E.coli level (800 CFU /100mL) associated with the piped water source was found in a tradiontal (uncoverd) water storage jar, which emphasizes the importance of appropriate water storage. Presentation Type and Session: Oral – Science, Mathematics and Technology Textural and Structural Connections Along the Metamorphic Field Gradient In Philadelphia, PA Jennifer Wehrfritz, Earth Sciences and Geology and Albert Tahan, Geology Faculty Mentor: Professor Gary Solar, Earth Sciences and Science Education The Wissahickon schist type locality along Wissahickon Creek in SE Pennsylvania (Philadelphia), is composed of pelitic schist (metamorphosed shale) interlayered with psammitic gneiss and quartzite (metamorphosed sandstone). The type locality is known for its complete record of [Barrovian] metamorphic zones. The metamorphic field gradient increases SSE in the creek valley for 5km from chlorite to second sillimanite zone, and at a high angle to the trend of the mineral-defined structures (fabrics). The chlorite zone in the N is within and adjacent to the ENE-striking, dextral-transcurrent Huntingdon Valley shear zone system (active at 300 million years ago). A transect along the creek is across both the metamorphic zones and the structural grain, permitting documentation of the relations between the metamorphic and deformation fabrics. We mapped along the east valley slope starting in the chlorite zone to the SSE for 2.8km, into the kyanite zone.
