Field Study of Abrasive Blasting with Quartz Sand: Factors Affecting the Potential for Incidental Exposure to Respirable Silica
Creators: name: Brantley, Charles D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: The use of quartz sand in high velocity abrasive blasting of steel is common in many Gulf Coast fabrication facilities. This activity has been recognized as generating high respirable silica concentrations in proximity to the blasting nozzles as evidenced by personal samples taken on blast workers over the years by several investigators. There remains limited published data useful to "plan" a sand blasting site such that other workers, however far away, are not exposed to damaging concentrations of respirable silica. Fixed sampling arrays consisting of personal respirable samplers (ACGIH and BMRC outpoints) and high volume samplers (using 8" x 10") filters were positioned in down-plume positions for 10 different worksites in a large Gulf Coast steel fabrication yard during the month of July 1991. Results of 126 gravimetric respirable samples, 34 high volume samples, 14 "zero dilution" chamber tests, and 42 analyses(contracted) for crystalline quartz demonstrated several interesting results. In general, downwind respirable silica concentrations varied as distance (D[-1.17]) from the source. The results were also consistent with Button's point source model (for the distances studied) where concentration varied as the distance (D[-1.76]) from the source. Source concentrations (0-50'from the blasting) measured by the fixed array averaged 3.61 mg/m[3]) but did not approach the "blast zone" concentrations measured by Samimi, et al— 37.2 mg/m[3]. Short-term sandblasting chamber studies to quantify a "zero dilution" generation rate yielded concentrations 2-3 orders of magnitude higher than the fixed array concentrations. Turbulent "free jet" mixing and sand blasting normal work patterns can explain various concentration magnitudes. Analytical results of crystalline silica analyses were comparable to gravimetric results such that their specification for a field study of sand blasting is not cost effective when the quartz content of the sand blasting sand is known. Using the data collected and the power laws studied it is estimated that 1100-2400 feet from the sandblast site airborne downwind concentrations will reliably dilute below the "action level" of 0.05 mg/m[3] respirable crystalline quartz.

description: What does it mean for the celebrated D#s in the first movement of
Beethoven's Violin Concerto to "stay in one's ear" during the time between their initial unresolved occurrence and their eventual resolution? What is it to hear such a thing? Or is the relevant experience not to be described as an auditory one?
Supposing that an account of an auditory experience can be given (one is offered), what if it is of such a nature as to seem unsuited to generalization? Then, presumably, occasion will have been found to countenance a music-theoretical posit without consistent auditory significance. Is this acceptable? To what conception of music theory might it be most congenial?

Effect of Ozonation on Cyanogen Chloride and Chloral Hydrate Formation
Creators: name: Smith, Marla Ellen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: The purpose of this research was to evaluate the impact of ozonation on the formation of chloral hydrate and cyanogen chloride produced by subsequent chlorination and chloramination. Chloral hydrate tends to be formed from chlorination while cyanogen chloride is formed primarily from chloramination. Raw waters and hydrophobic organic extracts were collected from five utilities across the United States to provide diversity in the organic material and water quality characteristics. Chloral hydrate and cyanogen chloride formation were investigated during chlorination and chloramination, both with and without pre-ozonation, of raw waters and model waters prepared from the extracted organic material. The raw waters were also subjected to coagulation experiments prior to post-chlorination and post-chloramination. In addition, ozone dose, total organic carbon (TOC)concentration, total inorganic carbon (TIC) concentration, ozonation pH, bromide ion concentration, and ammonia concentration were varied in the model waters in order to measure the influence of these parameters on chloral hydrate and cyanogen chloride formation. Pre-ozonation enhanced chloral hydrate formation from post-chlorination in all cases, and the extent of this increase was dependent upon the source of organic carbon. Pre-formed monochloramine did not produce appreciable amounts of chloral hydrate. Ozonation pH and TIC concentration were significant factors in determining chloral hydrate yields from post-chlorination, with chloral hydrate concentration decreasing with increasing ozonation pH or increasing TIC concentration. Chloral hydrate concentration from pre-ozonation/post-chlorination did not correlate well with acetaldehyde concentration resulting from pre-ozonation, implying that acetaldehyde is not a principal precursor to chloral hydrate formation. Pre-ozonation enhanced cyanogen chloride formation from post-chloramination. As with chloral hydrate, the degree of the increase depended on the source of organic carbon. Cyanogen chloride formation from post-chloramination was also impacted by ozonation pH and TIC concentration, with cyanogen chloride concentrations decreasing with increasing ozonation pH or increasing TIC concentration. The extent of cyanogen chloride formation from chloramination with pre-formed monochloramine correlated strongly with the concentration of formaldehyde resulting from pre-ozonation. This suggests that formaldehyde, a known oxidation by-product of ozone as well as chlorine, may be a principal precursor to cyanogen chloride formation.

James Kippen. The Tabla of Lucknow: A cultural analysis of a musical tradition. Cambridge: Cambridge University Press, 1988.
Creators: Manuel, Peter
Publisher: name: Columbia University
Year: 1991
Subjects: Music

description: The emphasis of many modern ethnomusicological studies has shifted away from the study of reified musical products to a more humanistic, anthropologically-informed focus upon musicians, socio-cultural contexts, performance norms, and emic conceptions about music. Kippen makes it clear that his intent is to "tread the middle path" between these two approaches, giving relatively equal weight to each. In such a relatively slim (222 pages) volume, such a treatment necessarily precludes the depth and breadth of the focussed studies of tabla music by Stewart and Gottlieb, as well as the extensive anthropological research of Neuman. Nevertheless, the emphasis on the under-researched Lucknow school and, more importantly, the abundance offresh insights and original material make Kippen's book a highly informative and valuable contribution to the study of Indian music.

description: Skew cyclic codes play the same role as cyclic codes in the theory of error-correcting codes for the rank metric. In this paper, we give descriptions of these codes by root spaces, cyclotomic spaces and idempotent generators. We prove that the lattice of skew cyclic codes is anti-isomorphic to the lattice of root spaces, study these two lattices and extend the rank-BCH bound on their minimum rank distance to rank-metric versions of the van Lint-Wilson's shift and Hartmann-Tzeng bounds. Finally, we study skew cyclic codes which are linear over the base field, proving that these codes include all Hamming-metric cyclic codes, giving then a new relation between these codes and rank-metric skew cyclic codes.

The Effectiveness of the 1985 Food Security Act - Highly Erodible Land Provisions to Reduce Agricultural Fugitive Dust Emissions
Creators: name: Harkrader, Deborah A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: Particulate emissions from agricultural activities pose health risks and contribute to violation of air quality standards in many areas. The potential effectiveness of the 1985 Food Security Act conservation provisions to reduce soil erosion and lower fugitive dust emissions on highly erodible cropland (HEL) was investigated. Nine states were surveyed on aspects of provision implementation. Criteria for evaluation, survey results, and sources of information are presented. The degree of the provisions' effectiveness varies. Conservation plans will protect large areas of HEL, yet emission reductions will be less than possible. The compliance and sodbuster provisions will continue into the future, and environmental benefits should increase over time. States where CRP enrollment is high will reap considerable air quality benefits, but the future of CRP is uncertain.

description: Steeply sloped roofs, low sloped roofs, flooded roofs and roof terraces discussed. A perfectly flat roof cannot be achieved in normal construction and slopes will inevitably develop owing to structural deflections. It is better to build in slopes to control water on a roof. The practicable minimum for main roof areas is about 1/4 inch per foot, and greater slope is desirable. Where drainage is achieved by a folded plate type of arrangement, crickets should be placed at the intersection of the larger slopes to direct water to the drains. When controlled flow drainage or evaporative cooling are required on roofs, a sloping roof produces a less hazardous condition than a flat roof. For protected membrane type roofs, the principal membrane at the deck below insulation and landscaping should be sloped, continuous and sealed round all penetrations.

Microbial Activity on Granular Activated Carbon Filter-Adsorbers
Creators: name: Cobb, Nathan C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1990

description: Granular activated carbon (GAC) used in the water industry as a filter material for the adsorption of organic compounds supports extensive colonization by microorganisms. The GAC filter-adsorber provides the environmental conditions that encourage microbial growth. Having a biological treatment process in drinking water production carries an implied health threat from opportunistic pathogens that may survive the disinfection barrier. There is some concern that microbially populated carbon particles are released in the product water of GAC filter-adsorbers. A pilot plant consisting of three GAC filter beds operated in parallel was assembled to explore the biological activity associated with GAC filter-adsorbers and evaluate the release of carbon fines in the product water. A polycarbonate filter apparatus was used to capture particulate matter in the product water for evaluation. Plate count data indicated lower application rates released more microbes to the product water than higher application rates. Backwashing the adsorbers with chlorinated water did not reduce colonization in the long term (beyond 30 days). Colonization reached a steady-state level of 10^5 to 10^7 CFU/g (dry weight) on the carbon and 10^4 CFU/mL in the product water. Coliform organisms were not found to propagate in the filter-adsorber. The average concentration of fines was estimated as 1.0 ug/L and scanning electron microscopy revealed that the particulate supported extracellular growth that could enhance survivability of microbes, but made the constitution of the matter indeterminable.

description: Maritime heterogeneous sensor networks (HSN) are widely used in support of marine monitoring, maritime security and safety applications and combine diversified sensing systems and platforms to observe the state of environmental features of interest or the status of anthropogenic objects to achieve awareness on the environment. The MSA-HSN ontology models HSN observations for maritime situational awareness (MSA). The MSA-HSN ontology is an integrated semantic model for maritime linked data, specifically observations suiting the requirements of maritime information fusion systems. MSA-HSN integrates established ontologies and models for sensors, observations, measurements, quantities, and occurrents, tailored to MSA applications and requirements. To support the interoperability with existing maritime data models, MSA-HSN is aligned with the relevant aspects of the EUCISE/e-CISE (Common Information Sharing Environment) data models. As a validation use case, the MSA-HSN ontology is applied to model the information elements of the maritime surveillance system developed within the Interactive Extreme-Scale Analytics and Forecasting (INFORE) project, where different situational views offered by a variegate suite of sensors and platforms are fused using big data analytics to achieve maritime situational awareness for maritime security.
 The design of the MSA-HSN ontology is illustrated in E. Camossi et al. "Maritime Linked Data for Situational Awareness Heterogeneous Sensor Networks" (preprint), which presents examples taken from the INFORE use case, in particular the hybrid robotic network described in Ferri et al. "A Hybrid Robotic Network for Maritime Situational Awareness: Results From the INFORE22 Sea Trial", and from relevant datasets developed by recent European projects involving MSA use cases.

description: The article continues the study of the genus of regular languages that the authors introduced in a 2012 paper. Generalizing a previous result, we produce a new family of regular languages on a two-letter alphabet having arbitrary high genus. Let $L$ be a regular language. In order to understand the genus $g(L)$ of $L$, we introduce the topological size of $|L|_{\rm{top}}$ to be the minimal size of all finite deterministic automata of genus $g(L)$ computing $L$. We show that the minimal finite deterministic automaton of a regular language can be arbitrary far away from a finite deterministic automaton realizing the minimal genus and computing the same language, both in terms of the difference of genera and in terms of the difference in size. In particular, we show that the topological size $|L|_{\rm{top}}$ can grow at least exponentially in size $|L|$. We conjecture however the genus of every regular language to be computable. This conjecture implies in particular that the planarity of a regular language is decidable, a question asked in 1976 by R.V. Book and A.K. Chandra. We prove here the conjecture for a fairly generic class of regular languages having no short cycles.

Mn(II) Dissolution from the Surface of Manganese Oxide-Coated Filter Media
Creators: name: Kim, Jakyum
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: Manganese oxides on the surface of filter media adsorb soluble manganese and organic matter in the water. Previous studies have suggested that surface coated manganese removes soluble manganese by adsorption and subsequent oxidation in the presence of oxidants at neutral pH's. However, the adsorbed Mn(II) and surface coated manganese oxide coatings can be dissolved from the surface of filter media under anoxic conditions and/or acidic conditions in the presence of adsorbed organics on the surface of the filter media. The first objective of this investigation was to determine what conditions might lead to dissolution of adsorbed Mn(II) and Mn02(s) from the surface of manganese-coated filter media. The second objective was to develop a better understanding of manganese dissolution by organics and solution pH in the absence and presence of free chlorine. The third objective was to recommend procedures to control the release of manganese from the filter media. Experiments were performed at pH 5.5 to 8.5 using TOC concentrations similar to those encountered in water treatment plants in the absence of and presence of free chlorine. Humic acid was used as the source of total organic carbon (TOC) in the feed water. The results demonstrated that dissolution of Mn(II) from the surface of manganese-coated filter media was a function of pH of the applied solution. Mn release was significant at pH values below 6.0, but was below 0.05 mg/l (the MCL for Mn) at neutral and alkaline pHs. TOC concentrations in the applied solution did not appear to influence the manganese dissolution rate significantly. Under acidic conditions, the application of free chlorine to the influent at a dosage sufficient to maintain a free chlorine residual controlled the release of manganese in the filter effluent. There was a potential for reduction of MnO2(s) and release of Mn^2+ to occur under acidic conditions unless chlorine was fed continuously.

description: Nonken's article critiques the content and focus of the Music Theory in Concept and Practice. She claims that although the, intention is to reflect the preoccupations of the field today. In this task, it succeeds only in part, that is not fully the case. In fact, the editors have chosen not to focus on the following influences, acknowledged in the introduction: computer science, linguistics, mathematics,
literary theory, gender studies, philosophy, aesthetics, and psychology.

description: The tensor square conjecture states that for $n \geq 10$, there is an irreducible representation $V$ of the symmetric group $S_n$ such that $V \otimes V$ contains every irreducible representation of $S_n$. Our main result is that for large enough $n$, there exists an irreducible representation $V$ such that $V^{\otimes 4}$ contains every irreducible representation. We also show that tensor squares of certain irreducible representations contain $(1-o(1))$-fraction of irreducible representations with respect to two natural probability distributions. Our main tool is the semigroup property, which allows us to break partitions down into smaller ones.

Retrospective Cohort Study of A Community Exposed To Herbicide: An Investigation of Perceived Acute Health Effects
Creators: name: Tolbert, Paige Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: Eighty-ͣfive subjects possibly exposed to herbicide following aerial spraying of Tordon 101 and Weedone 2,4-DP and 159 subjects from a referent, unexposed community were interviewed regarding exposure and health symptoms. The a priori hypotheses that exposure would be associated with reported worsening of respiratory symptoms and not with a dummy symptom were supported by the data. The relative risk for respiratory symptoms was thirteen. An exploratory analysis of responses regarding 32 symptoms indicated a significant association of exposure with eight symptoms: cough, difficulty breathing, sinus congestion, runny nose, swollen glands, wheezing, dizziness, and peeling skin. Adjustment for age, race, sex, smoking status, and educational attainment did not alter these findings. Those exposed subjects reporting a worsening, within a month, of any of the eight symptoms significantly associated with exposure, constituted the "reactor" group. Reactors so defined reported greater duration of exposure than the non—reacting exposed subjects. Reactors tended to be more educated and better acquainted with the identity of the sprayed material than the non-reactor's. The extent of over-reporting bias was assessed using dummy symptoms. This study constitutes the first epidemiological investigation of acute effects of community exposure to these herbicide formulations and demonstrates the importance of this type of community surveillance.

description: Leonard Meyer's splendid new book, Style and Music: Theory, History and Ideology, provides a rich feast of food for musical thought and (inevitably) for musical controversy. Theorists will, of course, be drawn to the author's nuts-and-bolts functional analyses of the various musical passages he discusses in making his argument; and music historians, doubtless, will find much to stimulate them, as well as to argue about, in his historical characterization of the Classical and Romantic periods in music and of their relevant social, political, and philosophical backgrounds. But philosophers of art like myself will surely fasten upon Meyer's bold attempt to connect the pure musical parameters of syntax and structure to the reigning ideologies with which they co-exist. Nor, I think, will it be out of place to concentrate on this attempt in the present review essay; for it is the major theme and argument of Meyer's book. I call the attempt to connect music and ideology "bold" because-and I think Meyer would agree-this is one of the most difficult and contentious things to make out in the "philosophy of music." In my view, it is one of the two master problems of the discipline, the other, to which it is obviously related, being the problem of making out exactly what the nature is, in the first place, of the aesthetic satisfaction we take in absolute music, given that such music seems, at least on the surface, bereft of semantic or representational content, and, yet, has come to occupy a place in the pantheon no less prominent than that accorded the semantic and representational
arts.
Keith W. Daniel. Francis Poulenc: His Artistic Development and Musical Style (Ann Arbor: UMI Research Press, 1982), 390 pp.

description: Defining a composer's style and artistic development is an imposing task. A composer's style is what makes his music his. A definition of that style would determine all the features common to individual works, separating those specific to the composer from those common to his contemporaries. An account of his artistic development would add to the definition of his style the sources and changing nature of that style. This is the central concern of Keith W. Daniel's book, the first complete survey of the music of Poulenc. Considering both the diversity of sources for Poulenc's style and the size and diversity of his output, Daniel set himself a sizable undertaking. While the resulting study does not reach any great depth in dealing with individual works or with Poulenc's style as a whole, the book is a good introduction to the composer's life and works. On the whole, Mr. Daniel is to be commended for providing an often provocative study. His method of analysis and discussion raises some questions about our assumptions in dealing with the music of a 20th-century composer who is viewed as basically conservative and traditional. Mr. Daniel has raised many issues worthy of further investigation. It is a fine first step in a better understanding of the composer and his works.

Multi-pair states in electron-positron pair creation

description: Ultra strong electromagnetic fields can lead to spontaneous creation of single or multiple electron-positron pairs. A quantum field theoretical treatment of the pair creation process combined with numerical methods provides a description of the fermionic quantum field state, from which all observables of the multiple electron-positron pairs can be inferred. This allows to study the complex multi-particle dynamics of electron-positron pair creation in-depth, including multi-pair statistics as well as momentum distributions and spin. To illustrate the potential benefit of this approach, it is applied to the intermediate regime of pair creation between nonperturbative Schwinger pair creation and perturbative multiphoton pair creation where the creation of multi-pair states becomes nonnegligible but cascades do not yet set in. Furthermore, it is demonstrated how spin and helicity of the created electrons and positrons are affected by the polarization of the counterpropagating laser fields, which induce the creation of electron-positron pairs.
An Investigation into Two Potential Sources of Variability in Chronic Testing with Ceriodaphnia dubia
Creators: name: Melia, Gregory M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Two studies were conducted to investigate potential sources of variability in chronic testing with Ceriodaphnia dubia. The first, was designed to compare survival and reproduction of three separate laboratory populations (clones) of C. dubia under identical conditions in standard culture and in their response to a toxicant (copper). The main purpose of the study was to ascertain whether genetic isolation of laboratory populations can contribute to inter-laboratory variability. A natural surface water, Botany Pond water, was used as a culture/dilution water in this study. Survival and reproduction for Sources 1 and 2 was nearly identical during 41 weeks of standard culture. Source 3 exhibited lower reproduction and higher variability than Sources 1 and 2 in standard, side by side culture. This difference was statistically significant (P<001) Source 3 exhibited the highest variability and the lowest average difference in reproduction between test treatments with copper and the corresponding controls. This made Source 3 more likely to 'pass' a toxicity test with copper as a toxicant, which was confirmed by the statistical analyses (P<0.01). These results indicate that laboratory population can be a determinant in the outcome of toxicity tests with C dubia. The second study examined the effect that differing time intervals between feeding and organism introduction into a toxicant solution can have on the outcome of toxicity tests. Copper was used as a toxicant and DMW (10% Perrier®/90% distilled-deionozed water) as the culture/dilution water. The results indicated that the toxicity response was moderate and relatively consistent, spanning treatments in which feeding occurred 5 minutes prior to organism introduction to where feeding occurred 4 minutes after organism introduction into the toxicant solution. Toxicity increased rapidly after a period of 4 minutes when the organism resided in the toxicant solution without food. A period of 7 minutes of organism-toxicant interaction without food resulted in consistent acute toxicity. These results indicate that small differences in feeding intervals between laboratories may result in different toxicity test results, thereby increasing inter-laboratory variability.
