Dimethyl (±)-(1s*,2r*,3s*)-[3-Phenyl-1-(N-Phenylcarbamoyloxy)-2, 3-Epoxypropyl]-Phosphonate, T. Boehlow, A. De La Cruz, N. P. Rath, C. D. Spilling

Christopher Spilling

The crystal structure of the racemic title compound, C18H20NO6P, m.p. 428-431 K, has been determined by X-ray diffraction. The title compound consists of a tetrahedral P atom bonded to two methoxy groups, and an alkyl chain. The alkyl chain was substituted at position 1 with a carbamate and with an epoxide at positions 2 and 3. The relative configuration of the 1-carbamate and 2,3-epoxide substituents was confirmed as anti (1S,2R,3S). The crystal structure contains an enantiomeric pair with two intermolecular hydrogen bonds in a 14-membered ring. The hydrogen bonds are formed between the P=O of one enantiomer and the N-H …

Combining Multi-Attribute Utility And Geographic Information For Boundary Decisions: An Application To Park Planning, Jeffrey Keisler, Ronald Sundell Nov 1997

Combining Multi-Attribute Utility And Geographic Information For Boundary Decisions: An Application To Park Planning, Jeffrey Keisler, Ronald Sundell

Jeffrey Keisler

The quality and value of an area depend primarily on what is found within
its designated boundaries. To determine the value of such areas in terms of boundaries,
we have developed a methodology for integrating multi-attribute utility functions with
spatial analysis so that desirable, or appropriate, boundaries can be determined on the
basis of the goals and objectives for the park. The key to successful evaluation is the
development of measures for what decision makers value, rather than merely using
what is easily measured. In a detailed example for planning of national parks, the
fundamental objectives are conservation and societal …

Photolithographic Patterning Of Vacuum-Deposited Organic Light Emitting Devices, Peifang Tian, P. E. Burrows, S. E. Forrest Nov 1997

Photolithographic Patterning Of Vacuum-Deposited Organic Light Emitting Devices, Peifang Tian, P. E. Burrows, S. E. Forrest

Peifang Tian

We demonstrate a photolithographic technique to fabricate vacuum-deposited organic light emitting devices. Photoresist liftoff combined with vertical deposition of the emissive organic materials and the metal cathode, followed by oblique deposition of a metal cap, avoids the use of high processing temperatures and the exposure of the organic materials to chemical degradation. The unpackaged devices show no sign of deterioration in room ambient when compared with conventional devices fabricated using low-resolution, shadow mask patterning. Furthermore, the devices are resistant to rapid degradation when operated in air for extended periods. This work illustrates a potential foundation for the volume production of …


A Vegetation Based Approach To Biodiversity Gap Analysis In The Agastyamalai Region, Western Ghats, India, B. R. Ramesh, Shaily Menon, Kamaljit S. Bawa Nov 1997

A Vegetation Based Approach To Biodiversity Gap Analysis In The Agastyamalai Region, Western Ghats, India, B. R. Ramesh, Shaily Menon, Kamaljit S. Bawa

Shaily Menon

Protected areas in India have historically been established on an ad hoc basis with little attention to the conservation value of an area. This study focuses on a set of protected areas in the Agastyamalai region of the Western Ghats (WG), India. We examine forest loss and land-use changes in the study area from the early 1900s to 1960 and from 1960 to 1990. We use GIS to perform a biodiversity gap analysis of the protected areas in the study site. We produce a detailed map of existing floristic types and use it to generate layers corresponding to floristic species …


Do Guaranteed-Low-Price Policies Guarantee High Prices, And Can Antitrust Rise To The Challenge?, Aaron S. Edlin Nov 1997

Do Guaranteed-Low-Price Policies Guarantee High Prices, And Can Antitrust Rise To The Challenge?, Aaron S. Edlin

Aaron Edlin

Price-matching policies can be highly anticompetitive. They allow firms to raise their prices above competition levels by discriminating in price between informed and uninformed customers. The resulting high prices can persist even when new firms enter the industry, a fact that gives price matching the potential to be much more socially costly than an ordinary monopoly or cartel. At the same time, widespread entry implies that the agreement among sellers that is typical of a Sherman Act price-fixing case may be absent. In this article, Professor Edlin argues that there is nonetheless an analogy between a seller offering (and agreeing) …

International Trade Between Consumer And Conservationist Countries, M. Scott Taylor, James A. Brander Oct 1997

International Trade Between Consumer And Conservationist Countries, M. Scott Taylor, James A. Brander

M. Scott Taylor

We consider trade between a Consumer country with an open access renewable resource and a Conservationist country that regulates resource harvesting to maximize domestic steady-state utility. In what we call the mild overuse case, the consumer country exports the resource good and suffers steady-state losses from trade, as suggested by the conventional wisdom that weak resource management standards confer a comparative advantage on domestic firms in the resource sector but cause welfare losses. Strikingly, however, when the resource stock is most in jeopardy, the conservationist country exports the resource good in steady state and both countries gain from trade.

What Buffalo Can Learn From Cleveland, Michael E Lewyn Oct 1997

What Buffalo Can Learn From Cleveland, Michael E Lewyn

Michael E Lewyn

Compares Buffalo to Cleveland, suggesting that Cleveland's downtown is more prosperous than that of Buffalo not because of its museums but because of its housing variety and police presence. The article goes on to suggest that Buffalo outside downtown is more prosperous than most of the city of Cleveland.


The Prevalence Of Pulmonary And Upper Respiratory Tract Symptoms And Spirometric Test Findings Among Newspaper Pressroom Workers Exposed To Solvents, Dean M. Hashimoto, Burton W. Lee, Karl T. Kelsey, Barbara Yakes, Teresa Seitz, David Christiani Sep 1997

The Prevalence Of Pulmonary And Upper Respiratory Tract Symptoms And Spirometric Test Findings Among Newspaper Pressroom Workers Exposed To Solvents, Dean M. Hashimoto, Burton W. Lee, Karl T. Kelsey, Barbara Yakes, Teresa Seitz, David Christiani

Dean M. Hashimoto

To investigate the relationship between exposure to organic solvents and the presence of pulmonary and upper respiratory tract mucous membrane symptoms, we conducted a cross-sectional study of 215 newspaper pressroom workers who were occupationally exposed to organic solvent and lubricant mixtures. Thirty-four compositors, who were not occupationally exposed to the solvents or lubricants, served as controls. Pressroom workers and compositors underwent spirometric testing and were also asked about the presence of cough, phlegm, hemoptysis, dyspnea, wheezing, chest tightness, nose or throat irritation, eye irritation, and sinus trouble. The spirometric results did not significantly differ between the two groups. However, the …

"I'M Gonna Git Medieval On Your Ass": Pulp Fiction For The 90s--The 1190s, Daniel Terkla, Thomas L. Reed, Jr. Sep 1997

"I'M Gonna Git Medieval On Your Ass": Pulp Fiction For The 90s--The 1190s, Daniel Terkla, Thomas L. Reed, Jr.

Daniel Terkla

Rarely does contemporary film offer any zippy ephemera to grace the office doors of medievalists, since film-makers like Quentin Tarantino do not often look to our discipline's corpus for inspiration. Imagine, then, the mix of incredulity and delight we two professors felt while taking in the pawn-shop scene in Tarantino's Pulp Fiction. After being painfully violated--anally raped, to be precise--and then rescued in a most chivalric manner by one of his minions, Marsellus Wallace swears an oath to Zed, his "hillbilly boy" rapist: "I'm gonna git Medieval on your ass" (Pulp Fiction 131). What? we thought: "Medieval"? Why, we asked, …

Gail Gasparich

Spiroplasma strain TALS-2T from the viscera of the striped horsefly, Tabanus lineola, collected in Georgia was serologically distinct from other Spiroplasma species, groups, putative groups, and subgroups. Light and electron microscopy of cells of strain TALS-2T revealed helical motile cells surrounded only by a single cytoplasmic membrane. The organism grew in M1D and SP-4 liquid media. Growth also occurred in 1% serum fraction medium and in conventional horse serum medium. Growth in liquid media was serum dependent. The strain passed through 220-nm filter pores, but was retained in filters with 100-nm pores. The optimum temperature for growth was 30°C. Multiplication …

Collaborative Roles For C-Jun N-Terminal Kinase, C-Jun, Serum Response Factor, And Sp1 In Calcium-Regulated Myocardial Gene Expression, Patrick M. Mcdonough, Deanna S. Hanford, Amy B. Sprenkle, Noel R. Mellon, Christopher C. Glembotski Sep 1997

Collaborative Roles For C-Jun N-Terminal Kinase, C-Jun, Serum Response Factor, And Sp1 In Calcium-Regulated Myocardial Gene Expression, Patrick M. Mcdonough, Deanna S. Hanford, Amy B. Sprenkle, Noel R. Mellon, Christopher C. Glembotski

Amy Sprenkle

Electrical stimulation of contractions (pacing) of primary neonatal rat ventricular myocytes increases intracellular calcium and activates a hypertrophic growth program that includes expression of the cardiac-specific gene, atrial natriuretic factor (ANF). To investigate the mechanism whereby pacing increases ANF, pacing was tested for its ability to regulate mitogen-activated protein kinase family members, ANF promoter activity, and the trans-activation domain of the transcription factor, Sp1. Pacing and the calcium channel agonist BAYK 8644 activated c-Jun N-terminal kinase (JNK) but not extracellular signal-regulated kinase. Pacing stimulated ANF-promoter activity approximately 10-fold. Furthermore, transfection with an expression vector for c-Jun, a substrate for JNK, …


Green And Ampt Infiltration With Redistribution, Fred L. Ogden Aug 1997

Green And Ampt Infiltration With Redistribution, Fred L. Ogden

Fred L. Ogden

Distributed, physically based watershed and irrigation advance models require robust infiltration estimation capabilities. The empirical Green and Ampt (GA) equation of infiltration is a popular method for estimating infiltration. The GA parameters have physical basis and considerable prior research has focused on relating these parameters to soil textural classification. However, the original GA method is limited in that it is applicable only for a single ponding period. An explicit Green and Ampt redistribution (GAR) technique is developed herein to estimate interstorm redistribution of soil water and allow multiple ponding simulations using the GA methodology. Soil water redistribution during interponding periods …

The Implicit Taxes From College Financial Aid , Aaron S. Edlin, Andrew W. Dick Aug 1997

The Implicit Taxes From College Financial Aid , Aaron S. Edlin, Andrew W. Dick

Aaron Edlin

Families who earn more or who heed the "experts'" advice and save for college typically receive less financial aid. The financial aid system therefore implicitly taxes both income and assets. We use NPSAS aid award data to estimate these implicit taxes, and find that at average-priced colleges the marginal income tax ranges from 2 to 16% and the marginal asset levy from 8 to 26%. A typical family loses aid worth about $11,000 at average-priced colleges and $15,000 at expensive colleges by accumulating an extra $50,000 in assets.


The Hanle Effect As A Diagnostic Of Magnetic Fields In Stellar Envelopes I. Theoretical Results For Integrated Line Profiles., R. Ignace, K. H. Nordsieck, J. P. Cassinelli Aug 1997

The Hanle Effect As A Diagnostic Of Magnetic Fields In Stellar Envelopes I. Theoretical Results For Integrated Line Profiles., R. Ignace, K. H. Nordsieck, J. P. Cassinelli

Richard Ignace

The Hanle effect concerns the modification of polarized resonance-line scattering by magnetic fields; thus, it can be used as a diagnostic of stellar magnetic fields. The Hanle effect has been used to determine the field strength and distribution of magnetic structures present in prominences of the Sun. To investigate its potential use in stellar astronomy, the simplified case of an optically thin axisymmetric ring illuminated by a stellar point source is considered. The results are then used to derive the polarization from polar plumes, equatorial disks, and spherical shells. The integrated line polarization is calculated for axisymmetric rings with a …
