PEPSI a Monte Carlo generator for polarized leptoproduction
No full textWe describe PEPSI (Polarized Electron Proton Scattering Interactions) a Monte Carlo program for the polarized deep inelastic leptoproduction mediated by electromagnetic interaction. The code is a modification of the LEPTO 4.3 Lund
Monte Carlo for unpolarized scattering and requires the standard polarization-independent JETSET routines to perform fragmentation into final hadrons
PEPSI: A Monte Carlo generator for polarized leptoproduction
No full textWe describe PEPSI (Polarized Electron Proton Scattering Interactions), a Monte Carlo program for polarized deep inelastic leptoproduction mediated by electromagnetic interaction, and explain how to use it. The code is a modification of the LEPTO 4.3 Lund Monte Carlo for unpolarized scattering. The hard virtual gamma-parton scattering is generated according to the polarization-dependent QCD cross-section of the first order in αS. PEPSI requires the standard polarization-independent JETSET routines to simulate the fragmentation into final hadrons
Radial anisotropy in the European mantle: Tomographic studies explored in terms of mantle flow
No full textPrevious studies have shown that radial seismic anisotropy as estimated from flow models is in good agreement with results from tomography at global scale, in particular underlying oceanic basins. However, the fit is typically poor at smaller scale lengths, particularly in tectonically complex regions. We conduct a comparative analysis of tomographically mapped and dynamically modeled radial anisotropy at the scale of Europe and the Mediterranean Basin, including three tomographic models based on different observations and/or methods. We find that adaptive-grid surface-wave tomography, with parametrization density depending locally on the spatial and azimuthal density of data coverage, leads to the seismic model closest to (albeit still far from) geodynamic predictions. The ability to map regional-scale seismic anisotropy may provide a new constraint, complementary to isotropic tomography, to the nature of upper mantle flow. Citation: Schaefer, J. F., L. Boschi, T.

FiFoSiM - an integrated tax benefit microsimulation and CGE model for Germany
No full textThis paper describes FiFoSiM, the integrated tax benefit microsimulation and computable general equilibrium (CGE) model of the Center of Public Economics at the University of Cologne. FiFoSiM consists of three main parts. The first part is a static tax benefit microsimulation module. The second part adds a behavioural component to the model; an econometrically estimated labour supply model. The third module is a CGE model which allows the user of FiFoSiM to assess the global economic effects of policy measures. Two specific features distinguish FiFoSiM from other tax benefit models: First, the simultaneous use of two databases for the tax benefit module and second, the linkage of the tax benefit model to a CGE model.FiFoSiM; microsimulation; CGE
Letter from L. P. Schaefer to L. De Bona requesting miscellaneous goods.
No full textLeonard de Bona was a businessman, possibly of Italian descent, in Eagle Pass, Texas, who ran a hardware and supply store in that area for nearly 20 years. He served as a point of contact for customers throughout South Texas and nearby Mexico, providing not only hardware but food, clothing, and sundries. He had business contacts in San Antonio, Chicago, and abroad (Central Mexico, Italy, and other locations.)Archive of Correspondence relating to L. de Bona's Eagle Pass Hardware and Supply Store from 1887-1903 and undated. Approximately 500 letters, varying states of condition, some browning. An important archive for a businessman on the border in Eagle Pass, Texas with nearly 500 letters, most from neighboring Texas communities, order supplies.Organized by the following series: Correspondence and ChronologicalBona, L. de, Papers, 1887-1903 and undated, Southwest Collection/Special Collections Library, Texas Tech University, Lubbock, Texa

Spectroelectrochemical characterisation of Langmuir-Schaefer films of heteroleptic phthalocyanine complexes. Potential applications
No full textThe Langmuir–Schaefer technique has been used to fabricate ordered monolayers of novel heteroleptic double and triple-decker phthalocyanine
derivatives. The molecules studied include a double-decker mixed porphyrinate and naphthalocyaninate lanthanum(III) compound and a
europium triple-decker molecule where one of the rings is a substituted porphyrin and the two remaining rings are substituted phthalocyanine
macrocycles.
The materials and their films have been characterised using UV–vis–NIR spectroscopy and electrochemistry. The UV–vis–NIR spectra of the
solutions show the expected features corresponding to the aromatic rings present in each molecule. The absorption spectra of LS films show
broadenings and important shifts to higher wavelengths when compared to the electronic absorption spectra of solutions or disordered cast films.
Thin films are sensitive to electron acceptor gases, such as NOx as observed by modifications in the electronic absorption spectra of the films.
These fast and reversible changes can be the basis of optical sensors based on thin films of heteroleptic phthalocyanines (Pc).
Cyclic and square wave voltammograms of dichloromethane solutions lead to rich curves where a variety of peaks are observed. The voltammogrames
of the corresponding films also reflect the rich electrochemical properties of the studied compounds.
Electrochromism has been found with LB and cast films electrodes in KCl and KClO4 solutions: important changes in the UV–vis–NIR spectra
registered in situ simultaneously to the application of the electrical potential have been observed. The rich electrochemistry and the electrochromism
observed, opens the possibility of using such films in multicolour electrochromic devices.
Films prepared onto ITO glass show characteristic electrochemical responses when exposed to solutions of organic compounds, such as ascorbic
and vanillic acid, providing a high degree of cross-selectivity. This effect can be used in the development of arrays of sensors used in electronic
tongues.
In summary Langmuir–Schaefer films of heteroleptic double and triple-decker phthalocyanines could be of interest at least in three potential
applications: thin film electrochromic devices, optical gas sensors and voltammetric sensors
Confidential Report: An Evaluation of a Criminal Justice Program
No full textThe Queensland Parole System Review recommended that all rehabilitative programs provided by Queensland Corrective Services be externally evaluated to ensure that they are effective in reducing reoffending and associated misbehaviours. In response to this call, the agency’s Research and Evaluation Unit commissioned evaluations of many of the agency’s programs. This report communicates the results of an evaluation of one such rehabilitative program, Queensland Corrective Services’ Cognitive Self-Change Program.No Full Tex
