Farm Chemicals As Indicators Of Sediment Sources In Iowa Rivers, George P. Malanson, E. N. Nealson
Farm Chemicals As Indicators Of Sediment Sources In Iowa Rivers, George P. Malanson, E. N. Nealson
George P Malanson
Determination of the source of sediment in rivers and streams is important in order to effectively implement a program to reduce its concentration. This project uses agricultural chemicals as indicators of current sources of sediment from farm fields in the Cedar River, Iowa watershed. We hypothesized that the relations of sediment, nitrogen, and phosphorous yields to precipitation would indicate whether sediment originated from erosion of fields or from channel bank erosion of floodplains. The changes in sediment, nitrate, and phosphorus in the channel in response to rainfall events were determined. In simple regressions, all three variables have similar slopes when …

Ordination Of Woody Vegetation In A Ouachita National Forest Watershed, George Malanson, Denise Marion
George P Malanson
Species response to competition and other environmental gradients has important implications for forest ecosystem managers who desire to both maintain diversity and provide a sustained flow of forest goods and services. Woody species on a 140-acre watershed in the Ouachita National Forest are ordinated with detrended correspondence analysis (DCA) and canonical correspondence analysis (CCA) to identify the important influences on species distribution at this scale. Species composition is found to respond primarily to a moisture gradient, and secondarily to competition with shortleaf pine (Pinus echinata Mill.). Centrifugal organization of species along gradients is suggested by the relative locations of species …

Reinterpretation Of Relations Between Vegetation Removal And Water Yield, George P. Malanson, D. P. Post
Reinterpretation Of Relations Between Vegetation Removal And Water Yield, George P. Malanson, D. P. Post
George P Malanson
While the relation between vegetation clearance and increasing streamflow appears to be strong for data aggregated among geographic regions, results are equivocal in local areas. Earlier data are re-analyzed to consider the role of hydroclimatology. While vegetation clearance increases absolute streamflow, the proportional change is not significant. Residuals of regressions of absolute and proportional change in streamflow on vegetation clearance are related to precipitation, with positive and negative slopes, respectively. A few outliers with high responses are important in creating a pattern, and hydroclimatology is a better predictor of change in streamflow than is vegetation clearance for aggregate data. With …

From Research Institution To Liberal Arts College: An Interview With Merrily Taylor, Eric C. Shoaf
Eric C. Shoaf
This article presents an interview with Merrily E. Taylor, the university librarian of Washington and Lee University in Lexington, Virginia. When asked on the similarities and difference of directing a small college library compared to a large one, Taylor states that it's the two libraries role to the institutional setting which makes them similar while it's their primary mission which makes them different. Taylor believes that her responsibility as a university librarian remains the same whether she is working for a small or large college library, it is the approach of carrying out the responsibilities which spells the difference.

Eric C. Shoaf
The article presents an interview with Florence Doksansky, interim university librarian at Brown University. Doksansky served as associate university librarian at Brown for twenty-one years until early 2004 when her supervisor resigned. Doksansky spoke about the challenges of being an interim director at a medium-size Association of Research Libraries library. The library was in the middle of a multi-year reorganization and into the second year of contract talks with unionized nonprofessional support employees who were working without a contract. In addition, budgets weren't keeping pace with inflation, the physical condition of the libraries was deteriorating and a new offsite storage …

John Boyle O'Reilly & Moondyne (1878), Susanna Ashton
Susanna Ashton Dr.
Arrested for treason against the British Crown and deported to the penal colonies of Australia, the Irish revolutionary John Boyle O'Reilly managed to escape to the United States and within a few years became one of Boston's most prominent political and literary figures, one of the best known Irish immigrants in the United States, and one of the most charismatic individuals of the late nineteenth century. He wrote some of the most popular poetry of the period as well as one obscure but swashbuckling novel, Moondyne (1878), based in part upon the spectacular
Microscale Tipstreaming In A Microfluidic Flow Focusing Device, Shelley L. Anna, Hans C. Mayer
Microscale Tipstreaming In A Microfluidic Flow Focusing Device, Shelley L. Anna, Hans C. Mayer
Shelley L Anna
A microfluidic flow-focusing device is used to explore the use of surfactant-mediated tipstreaming to synthesize micrometer-scale and smaller droplets. By controlling the surfactant bulk concentration of a soluble nonionic surfactant in the neighborhood of the critical micelle concentration, along with the capillary number and the ratio of the internal and external flow rates, we observe several distinct modes of droplet breakup. For the most part, droplet breakup in microfluidic devices results in highly monodisperse droplets in the range of tens of micrometers in size. However, we observe a new mode of breakup called “thread formation” that resembles tipstreaming and yields …

Geometrically Mediated Breakup Of Drops In Microfluidic Devices, D R. Link, Shelley L. Anna, D A. Weitz, H A. Stone
Shelley L Anna
Microfluidic technology offers capabilities for the precise handling of small fluid volumes dispersed as droplets. To fully exploit this potential requires simultaneous generation of multiple size droplets.We demonstrate two methods for passively breaking larger drops into precisely controlled daughter drops using pressure-driven flow in simple microfluidic configurations: (i) a T junction and (ii) flow past isolated obstacles.We quantify conditions for breakup at a T junction and illustrate sequential breakup at T junctions for making small drops at high dispersed phase volume fractions.
Highly Uniform Micro-Cavity Arrays In Flexible Elastomer Film, Shahab Shojaei-Zadeh, Shaun R. Swanson, Shelley L. Anna
Highly Uniform Micro-Cavity Arrays In Flexible Elastomer Film, Shahab Shojaei-Zadeh, Shaun R. Swanson, Shelley L. Anna
Shelley L Anna
Uniform hexagonal arrays of spherical micro-cavities are created in an elastomer film in a one-step process. The cavities are the imprints of water droplets condensed from saturated vapor in a heated closed container. The saturated vapor arises from evaporation of water from a reservoir within the container. Competition between droplet growth and curing of the elastomer film determines the structure of the resulting pattern.

Coalescence And Splitting Of Confined Droplets At Microfluidic Junctions, G F. Christopher, J Bergstein, N B. End, M Poon, C Nguyen, Shelley L. Anna
Shelley L Anna
The ability to merge two droplets is an important component of droplet-based lab-on-a-chip devices, yet flow-induced coalescence is difficult to achieve due to long film drainage times compared with relatively short residence times. We examine droplet collisions at a simple microfluidic T-junction and characterize the response for a wide range of droplet sizes and speeds. We find that three primary responses occur, where coalescence occurs easily at low collision speeds, smaller droplets traveling faster slip past one another without coalescing, and larger and faster droplets can break one another into multiple segments. The critical capillary number for coalescence agrees well …

Analysis Of Daily Activity Data From Implanted Cardiac Defibrillators: The Minimum Clinically Important Difference And Relationship To Mortality/Life Expectancy, Michael J. Shoemaker, Amy B. Curtis, Eric Vangsnes, Michael G. Dickinson, Rajib Paul
Michael J Shoemaker, PT, DPT, PhD, GCS
Background: Daily activity is a potentially important measure for assessing prognosis in individuals with chronic heart failure (CHF), and few studies have investigated the prognostic value of daily activity measurement. The present study sought to determine whether there is an association between daily activity and mortality/mean life expectancy as predicted by the Seattle Heart Failure Model (SHFM), and to provide an estimate of the anchor-based minimum clinically important difference (MCID) for daily activity measured by single-axis accelerometers in implanted cardiac defibrillators. Methods: This study utilized a retrospective chart review of 102 medical records of patients with CHF and Medtronic® implanted …

Eliminativism, Dialetheism And Moore's Paradox, John N. Williams
Eliminativism, Dialetheism And Moore's Paradox, John N. Williams
John N. WILLIAMS
John Turri gives an example that he thinks refutes what he takes to be “G. E. Moore's view” that omissive assertions such as “It is raining but I do not believe that it is raining” are “inherently ‘absurd'”. This is that of Ellie, an eliminativist who makes such assertions. Turri thinks that these are perfectly reasonable and not even absurd. Nor does she seem irrational if the sincerity of her assertion requires her to believe its content. A commissive counterpart of Ellie is Di, a dialetheist who asserts or believes that: Since any adequate explanation of Moore's paradox must handle …
Moore’S Paradox In Belief And Desire, John N. Williams
Moore’S Paradox In Belief And Desire, John N. Williams
John N. WILLIAMS
Is there a Moore’s paradox in desire? I give a normative explanation of the epistemic irrationality, and hence absurdity, of Moorean belief that builds on Green and Williams’ normative account of absurdity. This explains why Moorean beliefs are normally irrational and thus absurd, while some Moorean beliefs are absurd without being irrational. Then I defend constructing a Moorean desire as the syntactic counterpart of a Moorean belief and distinguish it from a ‘Frankfurt’ conjunction of desires. Next I discuss putative examples of rational and irrational desires, suggesting that there are norms of rational desire. Then I examine David Wall’s groundbreaking …
