description: The present work deals with adjusting a fine-grained microstructure in iron-rich iron-aluminium alloys using the ECAP-process (Equal Channel Angular Pressing). Due to the limited formability of Fe-Al alloys with increased aluminium content, high forming temperatures and low forming speeds are required. Therefore, tool temperatures above 1100◦C are permanently needed to prevent cooling of the work pieces, which makes the design of the ECAP-process challenging. For the investigation, the Fe-Al work pieces were heated to the respective hot forming temperature in a chamber furnace and then formed in the ECAP tool at a constant punch speed of 5 mm/s. Besides the chemical composition (Fe9Al, Fe28Al and Fe38Al (at.%—Al)), the influences of a subsequent heat treatment and the holding time on the microstructure development were investigated. For this purpose, the average grain size of the microstructure was measured using the AGI (Average Grain Intercept) method and correlated with the aforementioned parameters. The results show that no significant grain refinement could be achieved with the parameters used, which is largely due to the high forming temperature significantly promoting grain growth. The holding times in the examined area do not have any influence on the grain refinement. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

description: We produce SO2 molecules with a centre of mass velocity near zero using a Stark decelerator. Since the initial kinetic energy of the supersonic SO2 molecular beam is high, and the removed kinetic energy per stage is small, 326 deceleration stages are necessary to bring SO 2 to a complete standstill, significantly more than in other experiments. We show that in such a decelerator possible loss due to coupling between the motional degrees of freedom must be considered. Experimental results are compared with 3D Monte-Carlo simulations and the quantum state selectivity of the Stark decelerator is demonstrated.

description: A circular cylinder is tested in crossflow over the subsonic speed range. Time-resolved pressure distributions give information on surface pressure fluctuations; the corresponding drag and base drag coefficients are provided. Measured base pressure fluctuations at low Mach numbers are in agreement with the findings of other researchers. Flow changes at higher subsonic velocities and into the transonic range are described. Illustrations are drawn from the observations of other researchers, enabling physical explanations to be given to assist toward a more general modeling of the problem. At Mach numbers above 0.6 the changing strength of the vortices reduces the base drag coefficient up to a Mach number of 0.9, at which the onset of sonic flow increases the drag. Strouhal number variation is compared with the measurements of other authors. The paper concentrates on providing reliable measurements of vortex shedding and base pressure over the subsonic speed range rather than attempting to provide universal correlations.

Protecting Our Communities from Banking Mega-Mergers
Creators: name: Schlesinger, Tom
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: The banking industry mega-mergers announced last July and August are unprecedented in size. Analysts say others will surely follow. Many of the same analysts reassure us that huge banking combinations and industry- wide consolidation are natural, inevitable, good for banking and good for the economy. The Bush Administration asserts that encouraging big banks to get bigger will level the financial industry's domestic playing field and enhance the global position of U.S. banks. Rather than leveling the playing field, this bank-centered approach will only preserve its tilt. Underregulated firms, particularly giant financial companies, will continue playing a disruptive, lowest-common-denominator role at the fringe of the credit system. The bigger-is- better solution won't lay a glove on the underlying reasons the financial industry and lenders of all sizes flocked to ill-considered speculative investments over the past decade. The real culprits are regulatory inequality, weak supervision and decontrolled interest rates - not "too many banks." There is little evidence that increased size will make U.S.-based banks more competitive in global markets - or that such a result might yield benefits in this country. For example, the proposed NationsBank merger will produce the largest bank in recent U.S. history to have virtually no international presence. In addition to our skepticism about banking consolidation, the industry mega-mergers announced this summer raise three specific concerns: financial instability, economic dislocation, and concentration of economic power.
Assessing Community Credit Needs

description: (Reprinted from: A CRA Guidebook, published by HUD, written by HUD, U.S. Conference of Mayors, NCUA, CCC. August, 1979.) Establishing that a conmmunity has "unmet" credit needs" means, essentially, showing that lenders have failed to recognize creditworthy borrowers in a neighborhood. While lenders may legitimately deny credit because an individual cannot support a loan, or because the collateral is not valuable enough to cover the lender's risk, a community group may perceive that there are other reasons for lender reluctance to serve its area. It may feel that there are safe, secure and profitable loans which are not being made because the lender lacks information or expertise, discriminates, or just feels comfortable doing what it is doing. In building the CRA case, an organization will want to demonstrate a lender's lack of performance in making needed loans, the area's unmet need for loans, and the lender's capability for meeting that need. The following narrative outlines some of the major research sources which can be used to answer these questions. The first guidebook in this series, Assessing Community Credit Needs provides more detail on these research sources and techniques.

description: The fractional quantum Hall effect (FQHE) of topological surface-state particles under a tilted strong magnetic field is theoretically studied by using the exact diagonalization method. The Haldane's pseudopotentials for the Coulomb interaction are analytically obtained. The results show that by increasing the in-plane component of the tilted magnetic field, the FQHE state at $n$=0 Landau level (LL) becomes more stable, while the stabilities of $n$=$\pm1$ LLs become weaker. Moreover, we find that the excitation gaps of the $ν=1/3$ FQHE states increase as the tilt angle is increased.

description: Many municipalities in the United States, especially in rapidly growing areas, are considering or have adopted impact fee systems to help pay for the costs of new growth. Although such systems are a logical response to development pressures and the need for providing capital facilities, they may violate well-established planning law traditions. This timely article explores whether impact fee programs conflict with principles of planning and the due process of law, both of which have been integral to the development of modem planning law.

description: Purpose: The purpose of this study was to evaluate potential changes on a hierarchy of language tasks and measures of functional communication and quality of life in a group of people with aphasia (PWA) who attended a community aphasia center for 2 years. A secondary purpose was to determine whether there were any predictors of change. Method: Twenty-seven PWA who attended Brooks Rehabilitation Aphasia Center (BRAC) were evaluated on an aphasia battery, confrontation naming, and structured discourse in addition to completing self-reported measures of functional communication and quality of life at three time points: before attending BRAC and after 1 (N = 27) and 2 (N = 20) years of BRAC participation. Twenty-six communication partners who communicated regularly with the PWA completed a questionnaire about their functional communication at the same time points. A mixed linear model was conducted for all dependent variables to determine change over time. Tau-b correlations were conducted between demographic and aphasia-related variables and difference scores for outcome measures that exhibited significant improvements. Results: At 1-year testing, significant improvements were observed on the aphasia battery, object and action naming, and all self- and communication partner–reported measures. At 2-year testing, all improvements were maintained except for the self-reported measure of functional communication. Structured discourse showed increases in average number of words, percentage of meaningful words and utterances, and efficiency of meaningful word production after 2 years. No significant correlations were observed between predictor variables and difference scores. Conclusions: Participation in aphasia centers can result in significant changes in language, functional communication, and quality of life in people with chronic aphasia. These findings support the importance of aphasia centers in the continuum of care for PWA. Supplemental Material S1. Descriptions of BRAC groups. Supplemental Material S2. Linear mixed model details.

description: We study the low temperature expansion of the first law of thermodynamics for near-extremal black holes. We show that for extremal black holes with non-vanishing entropy, the leading order contribution yields an expression for their extremal entropy in agreement with the entropy function result and the Cardy formula for the entropy of a two dimensional chiral conformal field theory (CFT). When their entropy vanishes due to the vanishing of a one-cycle on the horizon, such leading contribution is always compatible with the first law satisfied by a BTZ black hole. These results are universal and consistent both with the presence of local AdS2 and AdS3 near horizon throats for extremal black holes and with the suggested quantum microscopic descriptions (AdS2/CFT1, Kerr/CFT and EVH/CFT).

description: For studies of the interface zone of metallic composites with significantly differing mechanical properties across the interface, high-quality sample preparation is paramount. In particular, the analysis of the composition or geometric characteristics of intermetallic phases close to the interface requires a preparation specifically adapted to the actual sample. In the present study, the combination of ion beam processing and a conventional metallographic preparation routine is investigated. It is shown that by utilizing a suitable combination of metallographic and ion beam processing routines, the interface zone of metallic composites can be prepared specifically targeted to a given analytical task. Especially for material combinations with largely differing mechanical properties of the base materials, ion beam processing can greatly improve the sample preparation quality. © 2020, The Author(s).

description: The Mn spin correlations were studied near the O'-O phase transition at T{JT} = 750 K, up to 950 K with 17O and 139La NMR in a stoichiometric LaMnO3 crystalline sample. The measured local hyperfine fields originate from the electron density transfered from the eg- and t2g-orbitals to the 2s(O) and 6s(La) orbits, respectively. By probing the oxygen nuclei, we show that the correlations of the Mn spins are ferromagnetic in the ab-plane and robust up to T{JT} whereas along the c-axis, they are antiferromagnetic and start to melt below T{JT}, at about 550 K. Above T{JT} the ferromagnetic Mn-Mn exchange interaction is found isotropic. The room temperature orbital mixing angle, ϕnmr = 109+-1.5°, of the eg ground state is close to the reported value which was deduced from structural data on Jahn-Teller distorted MnO6 octahedra. For T > T{JT} LaMnO3 can be described in terms of non-polarized eg-orbitals since both eg-orbitals are equally occupied.

title: Minimizing Post-Production Weight Growth in Tanks Using a Decision Analysis Model
Creators: name: Cochrane, Michael F.
Publisher: name: Old Dominion University Libraries
Year: 1997

description: Post-production weight growth of tanks is an historic problem for the military. Tanks are difficult to transport because of their weight, and post-production modifications tend to cause this weight to increase over the lifecycle of the tank. In this thesis, a computer model is constructed which uses influence diagrams to model tank weight growth as a probabilistic process. Historical weight data for the MI Abrams tank program is used to derive probabilities for the model. The model is used to predict tank weight growth over both the short and long term with the goal of understanding more about how and why tanks grow in weight after they are fielded. The analysis apportions the weight of a tank into three major sub-categories: survivability, mobility, and lethality. The model is used to explore ways in which the apportionment of weight to each of these categories can be adjusted to reduce the tendency toward weight growth given the same probabilities for weight growth.
Charlotte's Equity Loan Program: A Model for Financing Inner-City Redevelopment

Year: 2002

description: This article reviews equity loan programs for inner city neighborhoods in Charlotte and Greensboro, North Carolina. The author explains the need for capital in inner cities, then discusses the role of lending in neighborhood development. Three similar programs - Phoenix's collateral development program, the U.S. Housing and Urban Development Administration's New Markets Initiative, and the Corporation for Enterprise Development's Individual Development Accounts - are overviewed and compared with Charlotte's City Within A City equity program. The author conducts three analyses: 1) an outcome or performance-based analysis, 2) a process analysis of activity interest, and 3) an impact analysis that examines qualitative effects of two business on their respective neighborhoods. Early results suggest that the CWAC program has been successful, although some structural features limit the program 's effectiveness. Self Help has sought to replicate the success of this program in Greensboro. The author provides a set of recommendations for beginning such a program in Greensboro and other North Carolina cities.

description: In this thesis, the task to improve reactions that are already established or on the brink of commercialization is tackled in three different ways with the help of porous materials to develop dual-functional reactor systems, that improve not only the synthesis reaction itself, like the reaction rate or the selectivity, but also serve a secondary purpose as they improve product separation and longevity or are simultaneously used for waste removal. The first reaction discussed is the methylamine synthesis from methanol and ammonia at high temperatures. The addition of a highly hydrophilic, water removing Na-LTA zeolite membrane led to increased methylation rates in the product distribution. By choosing a size selective catalyst a high selectivity towards the desired product dimethylamine could be achieved, while the extraction of the by-product water pre-emptively decreased the need for post-synthesis product separation. With post-synthesis ion exchange, K-LTA membranes where achieved to further improve the methanol conversion rate. The methanol-to-olefins (MTO) reaction is a promising alternative for small olefin production. By applying the aforementioned Na-LTA to the MTO reaction, the varying product composition could be stabilized over a long period of time, while also providing product separation and an enhanced catalyst longevity. Besides the dualfunctional production/separation reactors, production/decomposition experiments were conducted with the utilization of the (dotted variant) porous monolayer carbon graphene, the durability of the important cocatalyst Cu0 in TiO2 photocatalysis was achieved and improved the yield of hydrogen in photochemical water splitting and facilitated the con-current decomposition of the pollutant 2-chlorophenol.

description: In this paper, we present an overview of ASTROD-GW (ASTROD [Astrodynamical Space Test of Relativity using Optical Devices] optimized for Gravitational Wave [GW] detection) mission concept and its studies. ASTROD-GW is an optimization of ASTROD which focuses on low frequency gravitational wave detection. The detection sensitivity is shifted by a factor of 260 (52) towards longer wavelengths compared with that of NGO/eLISA (LISA). The mission consists of three spacecraft, each of which orbits near one of the Sun-Earth Lagrange points (L3, L4 and L5), such that the array forms an almost equilateral triangle. The 3 spacecraft range interferometrically with one another with an arm length of about 260 million kilometers. The orbits have been optimized resulting in arm length changes of less than 0.00015 AU or, fractionally, less than 10^(-4) in twenty years, and relative Doppler velocities of the three spacecraft of less than 3 m/s. In this paper, we present an overview of the mission covering: the scientific aims, the sensitivity spectrum, the basic orbit configuration, the simulation and optimization of the spacecraft orbits, the deployment of ASTROD-GW formation, TDI (Time Delay Interferometry) and the payload. The science goals are the detection of GWs from (i) Supermassive Black Holes; (ii) Extreme-Mass-Ratio Black Hole Inspirals; (iii) Intermediate-Mass Black Holes; (iv) Galactic Compact Binaries and (v) Relic Gravitational Wave Background. For the purposes of primordial GW detection, a six spacecraft formation would be needed to enable the correlated detection of stochastic GWs. A brief discussion of the six spacecraft orbit optimization is also presented.

description: Raman spectroscopy has attracted interest as a non-invasive optical technique to study the composition and structure of a wide range of materials at the microscopic level. The intrinsic fluorescence background can be orders of magnitude stronger than the Raman scattering and so background removal is one of the foremost challenges for quantitative analysis of Raman spectra in many samples. A range of methods anchored in instrumental and computational programming approaches have been proposed for removing fluorescence background signals. An enhanced adaptive weighting scheme for automated fluorescence removal is reported, applicable to both polynomial fitting and penalised least squares approaches. Analysis of the background fitting results for ensembles of simulated spectra suggests that the method is robust and reliable, and can significantly improve the background fit over the range of signal, shot-noise and background parameters tested, while reducing the subjective nature of the process. The method was also illustrated by application to experimental data generated from aqueous solutions of bulk protein fibrinogen mixed with dextran.

description: Hablar hoy en día de salud mental es más común de lo que parece. Las estadísticas demuestran un incremento significativo de diversas sintomatologías que conducen rápidamente al padecimiento de una enfermedad de tipo mental, la cual requiere una atención pertinente por parte de nuestro sistema de salud. Años atrás, asistir al psicólogo y al psiquiatra era una situación difícil de afrontar, solo prescrita para personas “muy enfermas” y “locas” –llamadas así por algunos, de manera jocosa; por otros, de manera despectiva–; atendidas, según sus posibilidades, en lugares especializados, bajo una estricta medicación y un prolongado reposo, con inciertas expectativas de recuperación. Ahora, la percepción que tenemos de dichos profesionales de la salud ha ido cambiando. A causa de las diferentes situaciones que enfrentamos día a día en el trabajo, en la calle, en la familia, en la universidad, etc., es necesario recibir una orientación objetiva que nos permita canalizar pensamientos, ideas, sentimientos, puntos de vista y maneras de actuar frente a algún problema. Para quienes ya sufren de una patología mental específica, es necesaria la intervención oportuna por parte de un equipo multidisciplinario, que pueda ayudar a resolverla o sobrellevarla, con la menor interferencia posible en la vida diaria del paciente y sus relaciones con los demás

description: Due to the predominantly surface character of graphene, it is highly suitable for functionalization with external atoms and/or molecules leading to a plethora of new and interesting phenomena. Here we show ferromagnetic properties of hydrogen-functionalized epitaxial graphene on SiC. Ferromagnetism in such a material is not directly evident as it is inherently composed of only non-magnetic constituents. Our results nevertheless show strong ferromagnetism, which cannot be explained by simple magnetic impurities. The ferromagnetism is unique to hydrogenated epitaxial graphene on SiC, where interactions with the interfacial buffer layer play a crucial role. We argue that the origin of the observed ferromagnetism is governed by electron correlation effects of the narrow Si-dangling-bond (Si-DB) states in the buffer layer exchange-coupled to localized states in the hydrogenated graphene layer. This forms a quasi-three-dimensional ferromagnet with a Curie temperature higher than 300 K.

description: We provide a classification of translation invariant one-dimensional quantum walks with respect to continuous deformations preserving unitarity, locality, translation invariance, a gap condition, and some symmetry of the tenfold way. The classification largely matches the one recently obtained (arXiv:1611.04439) for a similar setting leaving out translation invariance. However, the translation invariant case has some finer distinctions, because some walks may be connected only by breaking translation invariance along the way, retaining only invariance by an even number of sites. Similarly, if walks are considered equivalent when they differ only by adding a trivial walk, i.e., one that allows no jumps between cells, then the classification collapses also to the general one. The indices of the general classification can be computed in practice only for walks closely related to some translation invariant ones. We prove a completed collection of simple formulas in terms of winding numbers of band structures covering all symmetry types. Furthermore, we determine the strength of the locality conditions, and show that the continuity of the band structure, which is a minimal requirement for topological classifications in terms of winding numbers to make sense, implies the compactness of the commutator of the walk with a half-space projection, a condition which was also the basis of the general theory. In order to apply the theory to the joining of large but finite bulk pieces, one needs to determine the asymptotic behaviour of a stationary Schrödinger equation. We show exponential behaviour, and give a practical method for computing the decay constants.

description: We investigate how coronal mass ejections (CMEs) propagate through, and interact with, the inner heliosphere between the Sun and Earth, a key question in CME research and space weather forecasting. CME Sun-to-Earth kinematics are constrained by combining wide-angle heliospheric imaging observations, interplanetary radio type II bursts and in situ measurements from multiple vantage points. We select three events for this study, the 2012 January 19, 23, and March 7 CMEs. Different from previous event studies, this work attempts to create a general picture for CME Sun-to-Earth propagation and compare different techniques for determining CME interplanetary kinematics. Key results are obtained concerning CME Sun-to-Earth propagation. Our comparison between different techniques (and data sets) also has important implications for CME observations and their interpretations. Future CME observations and space weather forecasting are discussed based on these results. See detail in the PDF.

Creating a Place-Based Vitality Index for Western North Carolina
Creators: name: Francis, Judy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Most planners working in the Western region of North Carolina are well aware that the region’s environment, economy, and cultural traditions are inextricably bound together from both historical and contemporary perspectives. Extraordinary mountain landscapes and globally-significant levels of biodiversity inspire entrepreneurial energy that manifests as exquisite art, enchanting music, and place-based industries that provide thousands of jobs and pump millions of dollars into the regional economy. Nurturing the region’s strengths and assets over time depends on our ability to see the connections between these diverse local assets and chart a future that is a sustainable response to the possibilities and limitations of this particular place. To this effect, the Western North Carolina Vitality Index (WNC Vitality Index), funded by the Mountain Resources Commission (MRC), is a new web-based decision support tool recently developed to inform decision-makers and the general public about sustainability issues in the western 27 counties.

description: An investigation is conducted on the acoustic resonance that develops in rectangular and cylindrical cavities with rigid walls. An analytical model for the small amplitude acoustic perturbations inside an enclosure with rigid walls is developed from classical linerized acoustics. The method is first applied to a rectangular geometry and the normalized mode shapes and frequencies of the first six standing wave modes are given. The results are used to diagnose whether coupling is likely to occur between the first two Rossiter modes and the acoustic standing waves, which may lead to a reinforcement of the flow instability. At the selected test conditions, the method indicates the likelyhood of such coupling for the second Rossiter mode. The acoustic resonant mode predictions for a cylindrical cavity of length to depth ratio 0.71 and 2.5, tested at near-incompressible speeds, suggest that the acoustic resonant modes and the fluid dynamic instability in the enclosure are sufficiently apart in frequency not to strongly interact with one another. The parametrized analytical solutions developed in this study enable the aeroacoustic engineer to diagnose whether coupling between a given fluid dynamic instability and acoustic resonance is likely to affect a rectangular or cylindrical cavity component.
Design, synthesis and properties of pharmaceutical cocrystals

description: Cocrystals are “solids that are single phase crystalline materials made up of two or more different molecular and/or ionic compounds generally in a stoichiometric ratio which are neither solvates nor simple salts.” A primary reason for current interest in cocrystals is down to their ability to alter the physicochemical properties of active pharmaceutical ingredients (APIs) without chemical modification of the API. That approximately 70% of new APIs under development have issues relating to low solubility and/or low permeability, means that cocrystals could overcome such issues and improve, for example, dissolution rate, stability and bioavailability of APIs. The development of crystal engineering principles has reached a level of maturity for certain types of functional groups, in particular carboxylic acid and pyridine moieties. This is not the case, however, for several other functional groups commonly found in APIs. In this context, this work addresses an understudied class of ionic cocrystals containing pharmaceutically acceptable dihydrogen phosphate (DHP) anions and phosphoric acid (PA) molecules and reports on their amenability to crystal engineering. The synthesis of cocrystals, particularly at scale, is often more challenging than that of single-component crystals and can be problematic with respect to purity, crystallinity and yield. This work highlights efficient methods for preparing and screening cocrystals. Most nutraceuticals are abundantly available within the plant kingdom and are associated with many beneficial health effects. Unfortunately, many of these nutraceuticals suffer from low aqueous solubility leading, in turn, to poor absorption in the body that hinders their clinical performance. Herein, this work demonstrates how cocrystals can be exploited to overcome these issues and offer an opportunity to prepare solid forms of nutraceuticals suitable for use in drug products.

description: Mead Stream in the Clarence Valley, north-eastern South Island, New Zealand, exposes a remarkable stratigraphic section through uppermost Cretaceous to Eocene formations. This section has been studied in detail since 1979 and has yielded internationally important data on the Cretaceous/Paleogene Boundary, the Paleocene–Eocene thermal maximum and several other global and regional paleoclimatic or paleoenvironmental events. The section has been sampled intensively for microfossil analyses (radiolarians, foraminifera, nannofossils, dinoflagellates), trace fossil analysis, paleomagnetic analysis and geochemical analysis (including stable isotopes). The section was damaged extensively during the Kaikōura earthquake sequence of November 2016, and safety considerations have prevented field work in the stream since that date. This report collates stratigraphic and sampling information gathered over almost 40 years, up until November 2016, onto a common measured section. Much of the measured section has been logged bed-by-bed at centimetre scale in order to facilitate future studies based on existing samples and new analyses. (auth)
