Uvrd Participation In Nucleotide Excision Repair Is Required For The Recovery Of Dna Synthesis Following Uv-Induced Damage In Escherichia Coli, Kelley Nicole Newton, Charmain T. Courcelle, Justin Courcelle

Biology Faculty Publications and Presentations

UvrD is a DNA helicase that participates in nucleotide excision repair and several replication-associated processes, including methyl-directed mismatch repair and recombination. UvrD is capable of displacing oligonucleotides from synthetic forked DNA structures in vitro and is essential for viability in the absence of Rep, a helicase associated with processing replication forks. These observations have led others to propose that UvrD may promote fork regression and facilitate resetting of the replication fork following arrest. However, the molecular activity of UvrD at replication forks in vivo has not been directly examined. In this study, we characterized the role UvrD has in processing …

Furthermore, the book …

Electric-Field-Induced Interfacial Instabilities Of A Soft Elastic Membrane Confined Between Viscous Layers, Mohar Dey, Dipankar Bandyopadhyay, Ashutosh Sharma, Shizhi Qian, Sang Woo Joo

Mechanical & Aerospace Engineering Faculty Publications

We explore the electric-field-induced interfacial instabilities of a trilayer composed of a thin elastic film confined between two viscous layers. A linear stability analysis (LSA) is performed to uncover the growth rate and length scale of the different unstable modes. Application of a normal external electric field on such a configuration can deform the two coupled elastic-viscous interfaces either by an in-phase bending or an antiphase squeezing mode. The bending mode has a long-wave nature, and is present even at a vanishingly small destabilizing field. In contrast, the squeezing mode has finite wave-number characteristics and originates only beyond a threshold …

Reimagining Criminal Prosecution: Toward A Color-Conscious Professional Ethic For Prosecutors, Justin Murray

Articles & Chapters

Prosecutors, like mostAmericans, view the criminal-justice system asfundamentally race neutral. They are aware that blacks are stopped, searched, arrested, and locked up in numbers that are vastly out of proportion to their fraction of the overall population. Yet, they generally assume that this outcome is justified because it reflects the sad reality that blacks commit a disproportionate share of crime in America. They are unable to detect the ways in which their own discretionary choices-and those of other actors in the criminal-justice system, such as legislators, police officers, and jurors-contribute to the staggering and disproportionate incarceration of black Americans. In …

Framing A Strategy: Exploring Faculty Attitudes Toward Library Instruction And Technology Preferences To Enhance Information Literacy, Maria A. Perez-Stable, Patricia Fravel Vander Meer, Dianna E. Sachs

University Libraries Faculty & Staff Publications

Higher education librarians and faculty members alike are faced with an ever expanding palette of technologies available for instructional use. Efforts between these two groups to collaborate in information literacy programs can greatly benefit from the incorporation of some of these new technologies. This article presents the results of a survey of 118 faculty members at Western Michigan University; conducted in 2011, it had three aims: (1) to gauge current faculty perceptions about library research instruction; (2) to determine how faculty are using technology in instruction; and (3) to examine faculty insights regarding the integration of different technological formats into …

Spatial And Temporal Variation In Degradation Of Dissolved Organic Carbon On The Main Stem Of The Lamprey River, Lucy Miller Parham

Master's Theses and Capstones

Degradation of dissolved organic carbon by microbial and photolytic processes was examined along the main stem of the Lamprey River Watershed located in southeastern New Hampshire. Eight sites were chosen and sampled biweekly throughout the seasonal hydrograph. Lab incubations were employed to assess microbial degradation of dissolved organic carbon (DOC) where one set of samples was exposed to natural sunlight for a day to assess photolytic degradation. Mean biodegradable dissolved organic carbon (BDOC) throughout the study period was 5.8% with no significant variation observed between sites. Temporal variation was found to be a much stronger driver of DOC composition with …

Apple Pomace As A Potential Ingredient For The Development Of New Functional Foods, Sofia Reis, Dilip K. Rai, Nissreen Abu-Ghannam

Conference papers

Apple pomace (AP) is the main by-product of cider industry being mainly composed of carbohydrates and dietary fibre, small amounts of protein, fat and ash. In addition AP is also a good source of phytochemicals such as phenolic acids and flavonoids making AP a valuable source of antioxidants. The common applications of this by-product are the direct disposal to soil in a landfill and for pectin recovery usage. These applications are not sufficient to drain the several tonnes produced every year and studies to valorise the AP for other purposes have gained momentum. AP due to its chemical composition, rich …

Harnessing Technology To Make Learning (And Teaching) More Fun., Barry Ryan, Julie Dunne

Conference papers

This paper describes how various technologies were introduced into foundation science modules both to enhance student engagement and feedback, and also to cope with increased teaching workload. It mostly deals with freely available software or tools available through a VLP (virtual learning platform, e.g. Blackboard or Moodle), but also includes audience response ‘Clickers’ which were purchased. The technologies discussed are user-friendly and do not require advanced IT skills. The paper includes successes, but also includes some less successful attempts to integrate technology and explores the possible reasons.

As third level funding is reduced, many academics are coming under increased pressure …

Newborns With Feeding Issues: Parental Perceptions Of The Hospital Discharge, Transition Home And The Role Of Speech Pathology, Katie Louise Ilich

Theses : Honours

This study explored the perceptions of discharge from hospital and the transition home for mothers of newborns with feeding issues. To gain an understanding of their experiences, mothers were interviewed twice, once at discharge and once up to a month later. Participants had a strong desire for their babies to be discharged from hospital, but felt anxious and underprepared. Once home, more questions typically arose. Mothers found this a highly stressful and emotional experience, especially for those without consistent speech pathology involvement. Mothers valued being involved in the decision-making process, and found this an effective coping mechanism. The value of …

Visual Memory Improvement In Recognition, Allison Prandl

Theses : Honours

Fluid intelligence and working memory has been improved by training on a visual working memory n-back task (Jaeggi, Buschkuehl, Jonides & Perrig, 2008). The present study investigated whether n-back training can improve visual memory using a test of visual recognition. A sample of 47 participants were trained for 20 days on either the single n-back task (n = 26) or a general knowledge and vocabulary task (n = 21). The results showed that training using the single n-back task did not significantly increase scores on a test of visual recognition when compared with general knowledge and vocabulary training. However, when …

Changing Land Use On Unproductive Soils, Andrew Blake, Mike Clarke, Angela Stuart-Street

Resource management technical reports

A three year study completed in 2010 examined farming systems in the north-eastern agricultural region and eastern wheatbelt of Western Australia which experienced a succession of variable seasons from 2000. This culminated in severe drought in 2006 and 2007. At that time, farmers experienced labour shortages and declining terms of trade triggered by cost inflation outpacing growth in commodity prices. As a result, farm business equity was eroded as farm debt escalated. This left many farm businesses in a highly vulnerable state. At the time of the study many farmers were facing an uncertain future.

These experiences, coupled with a …

Survey Of Glycerol Dialkyl Glycerol Tetraethers (Gdgts) In Nevada And California Hot Springs And Selected T Thermophiles, Julienne J. Paraiso, Amanda Jean Williams, Brian P. Hedlund, Chuanlun L. Zhang

McNair Poster Presentations

Glycerol dialkyl glycerol tetraethers (GDGTs) are core membrane lipids of many Archaea and some Bacteria found ubiquitously in soils and in many aqueous environments. Here, we examined the GDGT concentration in forty sediment samples from geothermal hot springs in the Great Basin (USA). Sediment samples were collected in tandem with extensive geochemical and site characterization. Hot spring temperatures ranged from 31 to 95°C and pH values from 6.8 to 10.7. Parametric Pearson's correlation coefficients and nonparametric Spearman's rho values were calculated to identify significant correlations between GDGT profiles and geochemical analytes. Isoprenoidal GDGTs (iGDGTs) negatively correlated with pH and positively …

Fungal Endophytes Directly Increase The Competitive Effects Of An Invasive Forb, Erik T. Aschehoug, Kerry L. Metlen, Ragan M. Callaway, George Newcombe

Biological Sciences Faculty Publications

Competitive outcomes among plants can vary in different abiotic and biotic conditions. Here we tested the effects of two phylotypes of Alternaria endophytes on the growth, competitive effects, and competitive responses of the exotic invasive forb Centaurea stoebe. Centaurea stoebe was a better competitor against North American grass species than grasses from its European home range in the absence of endophytes. However, one endophyte both increased the biomass of C. stoebe and reduced the competitive effect of North American grasses on C. stoebe. The competitive effects of C. stoebe on grass species native to North America were enhanced by both …

An Assessment Of The Carbon Balance Of Arctic Tundra: Comparisons Among Observations, Process Models, And Atmospheric Inversions, A. D. Mcguire, T. R. Christensen, D. J. Hayes, A. Heroult, E. Euskirchen, Y. Yi, John S. Kimball, C. Koven, P. Lafleur, P. A. Miller, Walt Oechel, P. Peylin, M. Williams

Numerical Terradynamic Simulation Group Publications

Although Arctic tundra has been estimated to cover only 8% of the global land surface, the large and potentially labile carbon pools currently stored in tundra soils have the potential for large emissions of carbon (C) under a warming climate. These emissions as radiatively active greenhouse gases in the form of both CO₂ and CH₄ could amplify global warming. Given the potential sensitivity of these ecosystems to climate change and the expectation that the Arctic will experience appreciable warming over the next century, it is important to assess whether responses of C exchange in tundra regions are likely …

New Species Of Gondwanamyces From Dying Euphorbia Trees In South Africa, Johannes Alwyn Van Der Linde, Diana Six, Michael J. Wingfield, Jolanda Roux

Ecosystem and Conservation Sciences Faculty Publications

Gondwanamyces and its Custingophora anamorphs were first described from Protea infructescences in South Africa. Subsequently these unusual fungi were also found on Cecropia in Central America. During an investigation into the decline and death of native Euphorbia trees in South Africa, several fungal isolates resembling the anamorph state of Gondwanamyces were obtained from diseased tissues. In this study these isolates are identified based on morphology and comparisons of DNA sequences. Two previously unknown Gondwanamyces species were identified, both were associated with damage caused by beetles (Cossonus sp.). Inoculation studies showed that the new species of Gondwanamyces are pathogenic on Euphorbia …

The Effect Of Fire On Spatial Separation Between Wolves And Caribou, Hugh S. Robinson, Mark Hebblewhite, Nicholas J. Decesare, Jessie Whittington, Layla Neufeld, Mark Bradley, Marco Musiani

Biological Sciences Faculty Publications

Fire management is an important conservation tool in Canada’s national parks. Fires can benefit some species, while others may be negatively impacted. We used GPS and VHF collar data for 47 wolves from 12 separate packs and 153 caribou from 5 separate herds, and resource selection analysis to model the effects of fire on these species’ habitat and potential interactions. Resource selection modeling showed that wolves select for burned areas and areas close to burns, presumably due to the presence of primary prey (i.e., elk and moose), while caribou avoid burns. Fire reduced the amount of high quality caribou habitat …

Christianity's Mixed Contributions To Children's Rights: Traditional Teachings, Modern Doubts, John Witte Jr.

Emory Law Journal

(CRC) is a landmark in the modern international protection of children's rights. Adopted by the United Nations General Assembly in 1989, its fifty-four articles and two Optional Protocols set out a lengthy catalogue of rights for children. The CRC bans all discrimination against children, including on grounds of their birth status. It provides children with rights to life; to a name, a social identity, and the care and nurture of both parents; to education, health care, recreation, rest, and play; to freedom of association, expression, thought, conscience, and religion; and to freedom from neglect or negligent treatment, from physical and …

Automated System To Improve Levelness Of Reconstructed Soil, Venkata Srikiran Bodapati, Larry G. Wells

Biosystems and Agricultural Engineering Faculty Publications

Extraction of coal, ores, and minerals from the earth by surface mining has occurred for many years and has always presented a significant challenge with regard to restoration of productive soil to mined areas. Federal and state regulations require that land should be returned to pre-mine productivity or reclaimed as per specific standards following mining. Excessive compaction of reconstructed soil caused by traffic of heavy earth moving equipment has been an enduring challenge regarding successful restoration of soil. A mechanical system was previously designed and developed to reconstruct soil to a depth of 1.22 m (48 in.) while completely avoiding …

Study Of Ph And Cellular Response In Pulmonary Fibroblasts After Exposure To Market Street World Trade Center Particulate Matter, Michelle Hernandez, Sung Choi, Ann Marie Dilorenzo

Department of Biology Faculty Scholarship and Creative Works

Chronic health conditions have been noted among first responders and residents exposed to the dust generated from the World Trade Center (WTC) collapse on September 11, 2001. This study sought to isolate a single factor thought to play a substantial role in the decreased lung function of World Trade Center (WTC) workers and victims. Human pulmonary fibroblasts were exposed to 0 (control), 2.5, 25, 250 mg mL-1 WTC dust at 5% CO2 and 10% CO2 to test the hypothesis that cellular toxicity is attributed to the high pH (9.3) of the WTC dust. A decrease in viability, increase in toxicity, …

Becoming Positive About Being Carbon Neutral:Requiring Public Accountability Forinternet Companies, Alexandra L. Pichette

Vanderbilt Journal of Entertainment & Technology Law

Every year, worldwide dependence on Internet and other information technology services grows. In many ways, the increased use of electric energy is positive for the environment; after all, using the Internet to access a document uses less energy than printing and distributing that document. Nonetheless, Internet companies expend a great deal of energy when they, for example, fire up their servers to satisfy a search request. Studies show that Internet companies are disproportionately large energy consumers, and are responsible for a growing number of carbon emissions. As a result, environmentalists are becoming concerned about the effects of these emissions on …

Evolutionary Relationships In Some Northern Groups Of The Direct-Developing Frog Genus Craugastor (Anura: Craugastoridae), Jeffrey W. Streicher

Biology Dissertations - Archive

Comparing phylogeographic patterns among vertebrates can give insight into the landscape and ecological determinants of phylogenetic diversity. However, in certain taxonomic groups (e.g., birds and mammals) natural history traits can be more influential in structuring phylogeographic patterns than historical interactions with the landscape. In contrast, groups like anurans (6132+ species) with poor dispersal capability and strict ecological requirements often display patterns of genetic diversification consonant with the geological and climatic characteristics of a landscape. The patterns resulting from these interactions can be used to elucidate the temporal dynamics of ecological differentiation, historical biogeography, and morphological evolution. The study of anurans …
