Second-Harmonic And Sum-Frequency Imaging Of Organic Nanocrystals With Photon Scanning Tunneling Microscope, Yuzhen Shen, Jacek Swiatkiewicz, Jeffrey G. Winiarz, Przemyslaw P. Markowicz, Paras N. Prasad

Chemistry Faculty Research & Creative Works

Second-harmonic generation and sum-frequency generation with photon scanning tunneling microscopy and shear-force detection are used to map the nonlinear optical response and the surface topograph of N-(4-nitrophenyl)-(L)-prolinol crystals with a subdiffraction-limited resolution. The domain-size dependence of the spatial feature is obtained, which shows the local orientational distribution of the optical near field radiated by nonlinear nanocrystals and reveals the difference between nanoscopic and macroscopic second-order optical nonlinearities of molecular crystals.

Sectoral Labor Choice In Post-Revolutionary Nicaragua: The Evolution Of The Informal Labor Sector In The 1990s, Michael Jack Pisani

Theses and Dissertations - UTB/UTPA

This dissertation focuses on the contemporary informal labor sector in Nicaragua. Central to the study are four research questions concerning the informal labor sector in Nicaragua; they are: (1) Are Nicaraguans positively or negatively selected into the informal/formal sector? That is, do Nicaraguans participate in their respective sector by choice (e.g., positive selection) or by force (e.g., negative selection)? (2) Are Nicaraguans working in the informal sector queued to work in the formal sector? (3) How has the queue changed, if any, for informal sector workers desiring formal sector employment over the course of the 1990s? and, (4) How have …

High Performance Micropane Electron Beam Window, Roger A. Dougal, Shengyi Liu

Faculty Publications

A silicon disk etched so that it contains a multitude of microscopic and thin window panes (micropanes) can potentially transmit a larger average electron beam current density and absorb a smaller fraction of the beam energy than a common metal foil window. The enhanced performance is achieved by a combination of decreased power loss due to the extremely small window thickness (~1 μm), and increased conductive cooling due to the small diameter (~50 μm) of the micropanes and the large cross section of the honeycomb structure that supports the micropanes. Beam current densities up to 34 A/cm2 are permitted within …

Organizing For National Security, Douglas Stuart Dr.

Books, Monographs & Collaborative Studies

Over the last decade the United States has been confronted with not just the collapse of the Soviet empire but also with revolutionary scientific breakthroughs, the transformation of the global economy, and the erosion of many of the basic premises of the Westphalian system of international order. The U.S. policy community has attempted to make sense of these and other changes by recourse to bodies such as the National Defense Panel and the U.S. Commission on National Security/21st Century (USNCS/21). The USNCS/21 is currently in the third phase of its mandated activities. At the end of phase three, the members …

Bronchiolitis Obliterans Organizing Pneumonia Associated With Pseudomonas Aeruginosa Infection, Daad H. Akbar, Omer S. Alamoudi

Saudi Medical Journal

Bronchiolitis obliterans organizing pneumonia is a rare disease characterized by the presence of granulation tissue within alveolar ducts and alveoli. Most cases are idiopathic, but it may also be seen during resolution of viral or bacterial pneumonia (mycoplasma, legionella and chlamydia). It may present as a community acquired pneumonia which does not respond to antibiotics, which make the diagnosis very difficult. We described a 53-year old patient who presented with Bronchiolitis obliterans organizing pneumonia during the resolution of pseudomonas aeruginosa pneumonia. Initially there was slight improvement on antibiotics but later he became severely hypoxic and placed on mechanical ventilator. Diagnosis …

Rhizosphere Competitiveness Of Trichloroethylene-Degrading, Poplar-Colonizing Recombinant Bacteria, Hojae Shim, Sadhana Chauhan, Doohyun Ryoo, Kally Bowers, Stuart M. Thomas, Keith A. Canada, Thomas K. Wood, Joel Gerard Burken

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Indigenous bacteria from poplar tree (Populus canadensis var. eugenei `Imperial Carolina') and southern California shrub rhizospheres, as well as two tree-colonizing Rhizobium strains (ATCC 10320 and ATCC 35645), were engineered to express constitutively and stably toluene o-monooxygenase (TOM) from Burkholderia cepacia G4 by integrating the tom locus into the chromosome. The poplar and Rhizobium recombinant bacteria degraded trichloroethylene at a rate of 0.8 to 2.1 nmol/min/mg of protein and were competitive against the unengineered hosts in wheat and barley rhizospheres for 1 month (colonization occurred at a level of 1.0 × 10⁵ to 23 × 10^{5 …}

Critical Reflective Practice And Workplace Learning : Impediments And Possibilities In Teacher Education, Barry Down, Carol Hogan

Australian Journal of Teacher Education

Professional practica are an essential part of teacher education and other professional education programs, but university staff often express concern that prac. experiences are fundamentally conservative, emphasising preparation for the status quo rather than for what might be. In recent years other forms of workplace-based university learning have been devised, where staff have sought to build units of study around a core of reflective practice, action research and professional development. This paper describes one such initiative, a final semester internship for fourth year education students which enabled them to design and negotiate their own professional development plans in any one …

Toward A Theory Of Technological Change, John Rodney Franklin

Student Scholarship

Theories of technological change are generally constructed based on assumptions that the technological artifact is a member of a historical line of technological advance (trajectory and evolutionary theories) or that novel technological developments simply "happen" (happenstance theories). Where a more constructivist view is taken technological change is assumed to be a social construct driven by the societal elements of human relationships and initiative. This paper takes a different approach to technological change positing that a combination of social structure and human agency act in a recursive manner to push a technological artifact forward. Using Anthony Giddens' structuration theory as the …

High Strain Rate Superplasticity In Microcrystalline And Nanocrystalline Materials, S. X. Mcfadden, A. V. Sergueeva, Rajiv S. Mishra, A. K. Mukherjee

Materials Science and Engineering Faculty Research & Creative Works

Superplasticity has evolved to become a significant industrial forming process. The phenomenon of superplasticity is explored at high strain rates where it is economically more attractive. True tensile superplasticity has been demonstrated in nanocrystalline materials. The difference in the details of superplasticity between the nanocrystalline and microcrystalline state is emphasised.

Binary Condensation In A Supersonic Nozzle, Barbara Ellen Wyslouzil, Christopher H. Heath, Janice L. Cheung, Gerald Wilemski

Physics Faculty Research & Creative Works

We present data from the first systematic studies of binary condensation in supersonic nozzles. The apparatus used to conduct the experiments is described in detail, and the important issues of stability and reproducibility of the experiments are discussed. Experiments were conducted with water, ethanol, propanol, and binary mixtures of these compounds. Onset was determined in the temperature range of 190-215 K, and for each mixture composition the pressures of the condensible species at an onset temperature of 207 K were determined. For the ideal ethanol-propanol mixtures, the onset pressures at constant temperature vary almost linearly between those of the pure …

Cruel, Mean, Or Lavish? Economic Analysis, Price Discrimination And Digital Intellectual Property, James Boyle

Vanderbilt Law Review

It is not because of the few thousand francs which would have to be spent to put a roof over the third-class carriages or to upholster the third-class seats that some company or other has open carriages with wooden benches .... What the company is trying to do is to prevent the passengers who can pay the second-class fare from travelling third class; it hits the poor, not because it wants to hurt them, but to frighten the rich .... And it is again for the same reason that the companies, having proved almost cruel to third-class passengers and mean …

Lessons From Studying The International Economics Of Intellectual Property Rights, Keith E. Maskus

Vanderbilt Law Review

When the Uruguay Round negotiations began in 1986, the subject of intellectual property rights ("IPRs") was completely unfamiliar to international trade economists. Presumably the area was ignored because global trade policy concerns had not moved into questions of domestic business regulation. Even today, readers will search in vain for serious treatments of the trade implications of exclusive rights to intellectual property ("IP") in international economics textbooks.

Despite this general inattention, a small but growing literature has emerged in which trade economists have framed specific questions and applied theory and statistical analysis to them. This literature has advanced the understanding of …

Dielectric Function Of Amorphous Tantalum Oxide From The Far Infrared To The Deep Ultraviolet Spectral Region Measured By Spectroscopic Ellipsometry, Eva Franke, C. L. Trimble, M. J. Devries, John A. Woollam, Mathias Schubert, F. Frost

Department of Electrical and Computer Engineering: Faculty Publications

Amorphous tantalum oxide thin films were deposited by reactive rf magnetron sputtering onto [001] silicon substrates. Growth temperature, oxygen partial pressure, and total gas pressure have been varied to obtain thin films with different densities. The thin films were analyzed by glancing angle-of-incidence x-ray diffraction, atomic force microscopy, and variable angle-of-incidence spectroscopic ellipsometry in the near infrared to vacuum ultraviolet spectral region for photon energies from E=1 to 8.5 eV, and in the infrared region from E=0.03 to 1 eV. We present the dielectric function of amorphous tantalum oxide obtained by line shape analysis of the experimental ellipsometric …

Thickness Analysis Of Silicon Membranes For Stencil Masks, E. Sossna, R. Kassing, I. W. Rangelow, C. M. Herzinger, T. E. Tiwald, John A. Woollam, Th. Wagner

Department of Electrical and Computer Engineering: Faculty Publications

Stencil masks are key to charged particle projection lithography, in particular for ion projection lithography. To fulfill pattern printing requirements in the sub-70 nm regime, excellent thickness uniformity and thermal emissivity control are critical parameters for high quality stencil mask fabrication. We propose and demonstrate a technique based on infrared variable angle spectroscopic ellipsometry (IR-VASE) to measure these parameters with adequate accuracy and precision. The refractive index of the Si membrane was evaluated using a Sellmeier dispersion model combined with a Drude model. Because of its spectral range from 2 to 33 μm, the IR-VASE method is sensitive to the …

Informal Aggregation: Procedural And Ethical Implications Of Coordination Among Counsel In Related Lawsuits, Howard M. Erichson

Duke Law Journal

Even when related claims are not aggregated by any formal procedural mechanism, the lawyers involved in the separate lawsuits often coordinate their efforts. Such "informal aggregation" raises important questions about the boundaries of a dispute and the boundaries of the lawyer-client relationship. As an ethical matter, the central question is whether a lawyer owes ethical duties to a coordinating lawyer's client. Looking at confidentiality, loyalty, conflicts of interest, and malpractice, Professor Erichson suggests that ethical safeguards for clients of coordinating lawyers are neither strong enough nor explicit enough to provide adequate protection, and the problem inheres in the nature of …
