• W-reactivation (Inducible "SOS" DNA Repair) of double stranded DNA bacteriophage ? and single stranded DNA bacteriophage fd on isogenic rec and uvrB mutants of Escherichia coli K-12

      Rothman, Robert H.; Ndive, Sammy F.W.; The College at Brockport (1983-05-01)
      The recA mutant has been shown to be completely recombination deficient and highly UV-sensitive. Also, this mutant is remarkably deficient in inducible "SOS" DNA repair and, consequently it is not UV-mutable and it cannot perform W-reactivation, an inducible non-excision repair dependent enhancement of phage recovery. The recB-recF- double mutant like the recA mutant, is recombination deficient and UV-sensitive. As observed, each of these mutations appear to block an independent pathway of genetic recombination. We are interested in determining how closely the recB-recF- double mutant resembles the recA mutant. In this perspective we looked at the W-reactivation of double stranded bacteriophage ? and single stranded bacteriophage fd. On examining the W-reactivation for phage ?, it is seen that the recB- and recF- mutants separately lead to a reduction of UV-reactivation efficiency but when spliced, the recB-recF- double mutant further leads to a reduction of W-reactivation even though this is still significant in magnitude when compared to the results obtained for the recA mutant. In the recA mutant W-reactivation capability is totally absent. Contrary to our results with bacteriophage ? , the recB- and recF mutants individually show enhanced W-reactivation of fd phage. The double mutant recB-recF- however, shows virtually no UV-reactivation potential. This is the same case for recA- mutant. Host-cell reactivation - an excision repair dependent potential was examined in the fd phage, ? vir and Pl vira. Our results demonstrate that host-cell recovery is non-existent in fd phage. On the other hand, we noticed high levels of phage recovery in ? vir and Pl vira. We have demonstrated that although recB-recF- double mutant closely resembles the recA single mutant in their UV-sensitivity and recombination profile, this resemblance is seen to be parallel when their UV-inducible capability is examined in double stranded bacteriophages. We therefore conclude that there are significant levels of inducible "SOS" DNA repair occurring in the recB- and recF- mutants and not in the double mutant, recB-recF-. This is due to the fact that there are genetic differences in the inducible DNA repair capability of single stranded and double stranded bacteriophages.
    • Wait Time- Is True Science Understanding Worth the Wait?

      Kennedy, Kathleen E.; The College at Brockport (2004-05-01)
      Science can be defined as a way of knowing about the natural world. From the time they are born, humans have a natural curiosity about everything they observe. Teachers need to foster this desire in their students as well as provide them with a vehicle in which they can discover the natural world. For this reason, teachers should help students develop an understanding of the definition of inquiry as well as the skills necessary to use inquiry in the science classroom. One tool that can be used is Wait-time. Wait-time can be defined as the periods of silence that follow teacher questions and completed student responses. Research has shown a variety of benefits derived from wait time. Wait time helps to achieve the National Science Education Standards, and has positive impacts on both student learning and teaching techniques. The first purpose of this project will be to analyze previous research on wait time since its conception, and demonstrate the benefits and possible detriments of wait time use. These benefits will be compared and contrasted for teachers in the Monroe and Wayne county school districts. In addition, I have created a series of "how" and ''why" questions relating to four thematic units that are part of the NYS Living Environment Regents curriculum These questions are specific to an activity that students will be engaged in as part of their learning. The activities, the objectives, how the NYS Standards are met, and a brief lesson plan will be included as part of my project. Teachers often overlook the importance of the questioning process in learning. I have found that there is a need for wait time in the classroom. Teachers should look for opportunities to implement wait time in every lesson and become aware of their role as a facilitator in the learning process. In my classroom, student inquiry did indeed improve. I found a more positive classroom environment, increased student participation, and in the end, enhanced student understanding. I will be asking these questions and incorporating wait time while completing each of these activities with my ninth grade living environment students. Two of the living environment classes contain many special education students. It is my hope that with a high quality questioning technique and sufficient wait time, there will be an increase in student questioning leading to inquiry and finally to content understanding. As a result of this project, I found I was no longer lecturing to the students. Instead I was facilitating class discussions. The students were in charge of their learning and I was simply guiding them. All students benefited from this change. They were all contributing and therefore all learning. Each student seemed to have a greater understanding of the material and higher expectations for their learning.Student test scores increased especially for the special education students. They not only achieved higher grades, but they seemed to expect more of themselves. On test and laboratory reports alike, students showed an increased interest in success.

    • Walleye (Sander vitreus) Stock Assessment (2006-2007) in the Buffalo River, NY, USA

      Herbert, Patrick J.; The College at Brockport (2010-03-01)
      Wall eye stock assessment The presence of a naturally occurring spawning stock of walleye (Sander vitreus) in the Buffalo River has gone undetected. This study sought to determine the extent of use of the Buffalo River by adult and juvenile walleye in 2006 and 2007 in order to assess the New York Department of Environmental Conservation' s stocking efforts. Walleye were first stocked in 2004 and stocking continued in 2005 and 2006. A total of 29 walleye, mostly juveniles, were caught during the two year study period. None of the walleye were believed to be using the river to spawn. The source of these walleye is not known but genetic analysis is pending. The Buffalo River and tributaries have limited habitat potentially suitable to support walleye spawning. No physicochemical conditions were observed that would preclude some successful walleye spawning in the Buffalo River watershed, but habitat conditions are not suitable for larval survival during movements to Lake Erie. Mean zooplankton density during the walleye larval period ranged from 4 1 .0- 86.4 individuals/L in 2006 and 2007, with rotifers being the dominant taxon in both years: 78% and 86%. Mean density of zooplankton at the river confluence with Lake Erie ranged from 2 1 . 8-25 . 1 individuals/L in 2006 and 2007. Rotifers were the dominant taxon in 2007 (73%) and cyclopoid copepods ( 40%) and rotifers (25%) were the dominant taxa in 2006. While abundance of zooplankton was adequate for walleye fry feeding, the predominance of smallbodied zooplankton was suboptimal. No ichthoplankton, including larval walleye, were caught during the study period despite intensive sampling. Fish community comparison: 2006 vs. 1981-1982 The Buffalo River, once a large industrial port for the City of Buffalo, has gone through great environmental stresses over the years. Through the development of environmental regulations and decline of industry in the City of Buffalo, the condition of the river has improved. The objective of this aspect of my thesis was to replicate a survey conducted in 1 98 1 - 1 982 (Makarewicz et al. 1982), using electro-fishing and gill netting, to determint1 the extent of change in the fish community. The fish communities of the Buffalo River exhibited similarities and differences between the surveys. Simpson's diversity was high (0.89) in 1 98 1 - 1 982 and in 2006 (0.9 1 ) but community similarity was only 48.3%. In 2006, 5 1 species from 1 4 families were caught. In 1 98 1 , 3 2 species from 1 0 families were caught. Twenty three species of fish captured in 2006 were not captured in 1 98 1 - 1 982. Four species caught in 1 98 1 - 1 982 were not caught in 2006. Centrarchidae ( 4 1 .4% ), Cyprinidae (20.7%), and Clupeidae ( 1 5 . 5 %) were the most commonly captured families in 2006. Cyprinidae (36.8%), Catostomidae ( 1 8 . 0%), and Centrarchidae ( 1 7.4%) were the most prevalent fan1ilies in 1 98 1 . Changes in the relative abundance of maj or families and the addition of many new species both indicate a change from a moderately pollution-tolerant to a less pollution-tolerant fish community during the 25 years between studies.

    • Warring Discourses in The Picture of Dorian Gray

      Appleby, Joseph T.; The College at Brockport (2006-01-01)
      Oscar Wilde's The Picture of Dorian Gray has enjoyed a myriad of critical treatment since its first publication. Much of this is due to the paradoxical nature of Wilde's style. In this novel, there is a tension and unique interplay between the discourses of ethics and Decadence as applied to the artistic life. Wilde's attraction to Catholicism also plays a prominent role in his treatment of characters. Although the author's intent remains ambiguous, the course of the novel leads one to the conclusion that there exists a fundamental incompatibility between Decadent and Catholic thought. The purpose of this thesis is to explore this incompatibility in all of its complexity. This thesis utilizes those works that have influenced Wilde, particularly the writings of Huysmans and Pater. Furthermore, it references Catholic writings and how they may apply to the ethical considerations put forth. Also, Wilde's life, as expressed through his letters, is brought to bear upon the analysis of the novel. Several critical writings on The Picture of Dorian Gray are also examined for their relevance and as a means to demonstrate the complex nature of the work and the possibility of a wide variety of interpretations. The thesis concludes with the notion that Wilde's novel cannot be seen as having one central discourse. Art and ethics have a certain interdependence despite conflicts between their fundamental propositions. Finally, the thesis proposes that the lack of resolution in The Picture of Dorian Gray stems from Wilde's developing understanding that would deepen with his profound experiences in the face of imprisonment and mortality.

    • Water Chestnut: Field Observations, Competition, and Seed Germination and Viability in Lake Ontario Coastal Wetlands

      Wilcox, Douglas A.; Des Jardin, Kathryn; The College at Brockport (2015-04-27)
      Water chestnut (Trapa natans L.) has recently invaded an increasing number of sites in New York State, particularly Lake Ontario coastal wetlands. It can severely inhibit ecosystem functioning and can be costly to control. To understand this exotic invasive plant more thoroughly, field observations and experiments were performed. The field observations were made in Lake Ontario coastal wetlands during the 2014 growing season. Percent coverage, time of flowering, time of seed production, and co-occurring species were noted. A competition experiment was performed using water chestnut and white water lily (Nymphaea odorata Aiton). They were planted together and in monocultures of differing densities. A greenhouse germination experiment in aquaria was conducted on water chestnut seeds using light and temperature as treatments, and seed-viability was examined to assess development stage and cold-stratification requirements. Water lily was the better competitor of the two, but water chestnut had very high germination success. Water chestnut germination does not seem to be inhibited by temperature or by exposure to shade. The seeds do, however, need to be mature and cold-stratified (subjected to a period of cold temperatures for dormancy) to germinate. Water chestnut’s tolerance to temperature, shade, and water depth has serious implications for Great Lakes wetlands if not controlled. There are a few control methods that could prove to be useful, but more research is needed before they are used in field settings. Early detection and manually pulling small patches of plants is a viable option at present.
    • Water Circulation in Lake Ontario

      Simons, T. J.; Murthy, C. R.; Campbell, J. E. (1985-01-01)
      Data from a high resolution array of self-recording current meters in a north-south cross section of Lake Ontario are presented. The measurements cover a 140-day period from 4 November 1982 to 23 March 1983. Nearshore current fluctuations are large and generally coherent with wind variations while currents in deep water tend to flow in the opposite direction and are quite uniform in the vertical. Time-averaged currents show a pronounced maximum of eastward flow along the south shore balanced by westward flow in the central part of the cross section, while the net transport near the northern shore tends to vanish. The total transport in the belt of eastward flow is ten times larger than the hydraulic transport associated with the Niagara-St. Lawrence flow, thus suggesting a recirculation of 90% of the river inflow. Corroboration of the south shore current measurements is provided by satellite-tracked drogues.
    • Water Quality Analysis of Black Creek Watershed: Identification of Point and Nonpoint Sources of Pollution and Loading Simulation Using the SWAT Model

      Winslow, Mellissa Jayne; The College at Brockport (2012-02-01)
      Nearshore Lake Ontario suffers from several beneficial use impairments due to water quality issues from the Genesee River and its contributing tributaries. Segments of Black Creek located in the Lower Genesee River basin are listed as impacted on the New York State 303(d) list because of excess sediment, nutrient, and bacteria losses. Sources of these pollutants from the Black Creek watershed include improperly managed cropland and pastures, dairy manure application, and effluent discharges from wastewater treatment plants. An assessment of the Black Creek watershed was undertaken to determine the nutrient and sediment contribution of Black Creek to the Genesee River and to determine sources of nutrients and sediment loss geospatially within the watershed. To accomplish this task, a multifaceted, integrated approach was taken by combining stream monitoring, segment analysis, and hydrologic modeling [Soil and Water Assessment Tool (SWAT)]. The annual losses (June 2010 through May 2011) of total phosphorus (TP), total nitrogen (TN), and total coliform bacteria from the Black Creek watershed were 16.5 MT/yr, 349.4 MT/yr, and 7.0E15 CFU/yr, respectively, where most of the losses occurred in the upper portion of the watershed. Impacted tributaries (Bigelow Creek and Spring Creek) had the highest areal loads of nutrients and bacteria and were a focus for remediation. More than 70% of the TP load was found to be due to anthropogenic sources including but not limited to manure applications from Confined Animal Feeding operations, the Bergen wastewater treatment plant, and nonpoint agricultural practices throughout the watershed. Sediment loss, on the other hand, was the highest in the downstream reaches of Black Creek where 73% of the total sediment load (8,360.6 MT/yr) occurs due to excessive flooding and stream bank erosion during events. These findings were used to calibrate a SWAT model for Black Creek that simulated the impact of implementing several Best Management Practices (BMPs) to reduce phosphorus and sediment loads. Individual BMPs reduced TP loads from Black Creek at Lower BC anywhere from 0 to 28% and sediment 0 to 84%. A holistic approach to watershed remediation using a combination of several effective BMPs focusing on major contributors of phosphorus and sediment reduced TP 28% and total suspended solids (TSS) 73%. This remedial action plan, if implemented, can reach a water quality target of 65 ?g P/L proposed by the Department of Environmental Conservation, which would reduce the annual TP concentration from 79.6 ?g P/L to 38.3 ?g P/L. This scenario can be used to determine an appropriate Total Maximum Daily Load for Black Creek that will help attain the ultimate goal of reducing the impairments of nearshore Lake Ontario.
    • Water Quality Assessment of Irondequoit Creek using Benthic Macroinvertebrates

      Bailey-Billhardt, Nichelle; The College at Brockport (2002-01-01)
      The Rochester Embayment of Lake Ontario is one the 43 Great Lakes' Areas of Concern designated by the Environmental Protection Agency (Monroe County 1993). As part of a Remedial Action Plan (RAP), degradation ofbenthos was one of the 14 use impairments identified for the Rochester Embayment (Monroe County 1993). Stage II of the RAP identified stream health monitoring as a method of identifying existing and future conditions of the Embayment and its tributaries, including Irondequoit Creek. There is much debate in the "world" of stream health biomonitoring using aquatic macro invertebrates regarding methods of collection, sample size and taxonomic resolution required to obtain accurate stream health assessments. My study compared stream health at three locations in Irondequoit Creek (upstream, midstream and downstream) and in three habitats (gravel, mud and vegetation) and evaluated methods of sampling macro invertebrates and analyzing stream health used by the Stream Biomonitoring Unit ofthe New York State Department ofEnvironmental Conservation (Bode et al. 1996). There were few differences between upstream (primarily agricultural or rural land use) and midstream (primarily agricultural and suburban l~d use) communities, but stream health decreased from upstream to downstream (primarily .urban/suburban land use). As expected, community differences were found across habitats (gravel, vegetation, mud) at the same sampling locations. Fixed 100 count · methods were compared with entire macro invertebrate samples in the gravel habitat at the midstream location (Powder Mill Park, Rochester, NY). Although metric values for random and haphazard samples of 100 organisms differed from values for whole samples, stream health assessments did not differ.
    • Water Quality at the Inlet to the St. Lawrence River, 1977 to 1983

      Sylvestre, A.; Kuntz, K. W.; Warry, N. D. (1987-01-01)
      Daily nutrients analyses and weekly major ions and trace metals analyses have been performed since 1977 on water samples collected in the south channel of the St. Lawrence River at Wolfe Island. This report presents the results of the first seven years of this program. Data analyses showed that pH and total phosphorus were underestimated. Calcium carbonate precipitation is suspected to occur almost every year in August or September. Most of the major ions have decreased, especially chloride and sodium. All trace metal data were below the objectives of the International Joint Commission in 90% of the cases or more. The Wolfe Island station was found to be a good tool for following the general trend of the main water quality parameters. More attention, however, should be focused on the problems of shipping delays and containers.
