Abstract: We present the analysis of the resolved resonance region for the 234U(n,f) cross section data measured at the CERN n TOF facility. The resonance parameters in the energy range from 1 eV to 1500 eV have been obtained with the SAMMY code by using as initial parameters for the fit the resonance parameters of the JENDL-3.3 evaluation. In addition, the statistical analysis has been accomplished, partly with the SAMDIST code, in order to study the level spacing and the Mehta-Dyson correlation.

Abstract: The neutron capture cross section of (206)Pb has been measured at the CERN n_TOF spectrometer using a setup of two C(6)D(6) detectors. In the energy interval from 1 eV to 600 keV the cross section is dominated by resonances, which were analyzed via the R-matrix analysis code SAMMY. In the relevant energy ranges for stellar nucleosynthesis, i. e., at thermal energies of kT = 8 keV and kT = 23 keV, the present Maxwellian average cross section differs by 20% and 9% from the recommended values of Bao et al respectively. From the new cross section the s-abundance of (206)Pb could be reliably determined as 70( 4)%. This result is of importance in order to test and constrain r-process abundance calculations in the actinide region, because the r-process portion of (206)Pb is dominated by alpha-back decays of short-lived transbismuth isotopes.

254. Regulation of bradykinin receptor gene expression in human lung fibroblasts

Abstract: In WI-38 human fibroblasts, interleukin-1 beta and tumour necrosis factor-alpha (TNF-alpha) increased bradykinin B(1) receptor mRNA, which peaked between 2 and 4 h, remaining elevated for 20 h. Binding of the bradykinin B(1) receptor selective ligand [3H]des-Arg(10)-kallidin, also increased, peaking at 4 h and remaining elevated for 20 h. The B(max) value for [3H]des-Arg(10)-kallidin rose from 280+/-102 fmol/mg (n=3) to 701+/-147 fmol/mg (n=3), but the K(D) value remained unaltered (control, 1.04+/-0.33 nM (n=3); interleukin-1 beta, 0.88+/-0.41 nM (n=3)). The interleukin-1 beta-induced [3H]des-Arg(10)-kallidin binding sites were functional receptors, as bradykinin B(1) receptor agonist-induced responses increased in treated cells. Bradykinin B(2) receptor mRNA and [3H]bradykinin binding were upregulated by interleukin-1 beta, but not TNF-alpha. The effect of interleukin-1 beta on bradykinin B(2) receptors was smaller than for bradykinin B(1) receptors. Cycloheximide prevented interleukin-1 beta-mediated increases in B(1) and B(2) binding, but not mRNA suggesting that de novo synthesis of a transcriptional activator was unnecessary.

Abstract: 5 pages, 2 figures.-- PACS nrs.: 29.25; 28.20.−v; 24.30.−v; 98.80.-- ISI Article Identifier: 000248784100221, Printed version published Aug 2007.-- Issue title: The Application of Accelerators in Research and Industry - Proceedings of the Nineteenth International Conference on The Application of Accelerators in Research and Industry (Fort Worth, TX, Aug 20-25, 2006)., The neutron time-of-flight facility n_TOF at CERN, fully operational since 2002, combines a high instantaneous neutron flux with high energy resolution. The wide energy range and the high neutron flux per time-of-flight burst result in a much enhanced signal to background ratio for neutron capture of radioactive isotopes and makes this facility well suited for the measurement of high quality neutron-induced reaction cross-sections., Neutrons are created by spallation reactions induced by a pulsed 20 GeV/c proton beam impinging on a lead target. A 5 cm water slab surrounding the lead target serves as a coolant and at the same time as a moderator of the spallation neutron spectrum, providing a wide energy spectrum from 0.1 eV to about 250 MeV., By the end of 2005, a first phase of data taking has been successfully terminated. Fission and capture experiments have been performed on a variety of isotopes of interest for nuclear astrophysics, advanced nuclear technologies and for basic nuclear physics., The instrumentation developed for this facility consists of parallel plate avalanche counter and fission ionization chamber detectors for the fission experiments and of low mass C6D6 detectors and a 4 pi BaF2 total absorption calorimeter for capture experiments. A new data acquisition system, based on sampling of the detector signals, has been developed to cope with the high count rates and to minimize the effective dead time to only a few tens of nanosecond., A second phase of data taking is planned to start in 2007, after an upgrade of the spallation target. On the longer term, the construction of a flight path at 20 in resulting in an increased neutron flux of about a factor of 100 opens new possibilities.

Abstract: The neutron capture cross section of 204Pb has been measured at the CERN n_TOF installation with high resolution in the energy range from 1 eV to 440 keV. An R-matrix analysis of the resolved resonance region, between 1 eV and 100 keV, was carried out using the SAMMY code. In the interval between 100 keV and 440 keV we report the average capture cross section. The background in the entire neutron energy range could be reliably determined from the measurement of a 208Pb sample. Other systematic effects in this measurement could be investigated and precisely corrected by means of detailed Monte Carlo simulations. We obtain a Maxwellian average capture cross section for 204Pb at kT=30 keV of 79(3) mb, in agreement with previous experiments. However our cross section at kT=5 keV is about 35% larger than the values reported so far. The implications of the new cross section for the s-process abundance contributions in the Pb/Bi region are discussed., Comment: 8 pages, 3 figures, article submitted to Phys. Rev. C

Abstract: The aim of this study was to test the effect of acetosyringone (AS) on the accumulation of the histidine kinase coding mRNA, using in vitro propagated Pisolithus tinctorius. In the precontact phase of the ectomycorrhizal symbiosis, it is hypothesized that the plants releases chemicals, which are sensed by the fungal mycelium and in turn trigger the start of the symbiosis. The nature of such molecules is largely unknown; however, plant metabolite and their structural analogues have been widely used to induce infection in different microbe-plant interactions. A histidine kinase in Agrobacterium tumefaciens was activated by AS in the first step during the infection of dicotyledonous plants. A conserved gene fragment from the ectomycorrhizal fungus Pisolithus tinctorius was cloned using degenerate primers of conserved regions characteristic of the histidine kinase gene family. Then, the accumulation of this transcript in fungi incubated with AS was analyzed. RT-PCR and in situ hybridization suggest that this mRNA is synthesized in the presence of this plant analog in AS-treated mycelia. The findings presented here suggest a role of a histidine kinase involved in the early stages of ectomycorrhizal differentiation.

Abstract: Durante el año de 1991 se realizaron muestreos con frecuencia bimestral en el embalse de Betania (alt.: 560 m.s.n.m.; área: 7.4 km2; volumen 1971x106 m3; prof. media: 28 m) en el departamento del Huila, con el objetivo de determinar la composición del zooplancton. En total se registraron 24 taxa: Thermocyclops decipiens (Crustacea, Copepoda), Moina sp., Ceriodaphnia cornuta y Allona sp. (Crustacea, Cladocera); 19 especies de rotíferos, de los cuales 7 corresponden al género Brachionus y larvas del díptero Chaoborus sp. Se registran por primera vez para Colombia Brachionus havanaensis, B. falcatus falcatus, b. quadridentatus, y Platyias cuadricornis f. brevispinus. A partir de la comparación con faunas zooplanctónicas de varios cuerpos de agua tropicales y subtropicales, se concluyó que la composición zooplanctónica del embalse es típica de lagos tropicales cálidos. To determine the species composition of the zooplancton in the reservoir Betania (altitude; 560 m.a.s.l.; area: 7.4 km2; vol: 1971 x 106 m3; mean depht 28 m), at seven sites and several depths, bimonthly net samples (100 and 200 microns mesh size) were taken during 1991. Alltogether 24 species were found: Thermocyclops decipiens (Crustacea, Copepoda), Moina sp., Ceriodaphnia cornuta y Allona sp. (Crustacea, Cladocera); 19 species of rotífers, of which 7 belong to the genus Brachionus, as well as larvas of the dipter Chaoborus sp. For the first time Brachionus havanaensis, B. falcatus falcatus, b. quadridentatus, y Platyias cuadricornis f. brevispinus were found in Colombia. The species composition was compared with the composition of other lakes and comparison shows that the Betania reservoir has a typical species composition for warms tropical lakes.

Abstract: The radiative neutron capture cross section of 207Pb has been measured at the CERN neutron time of flight installation n_TOF using the pulse height weighting technique in the resolved energy region. The measurement has been performed with an optimized setup of two C6D6 scintillation detectors, which allowed us to reduce scattered neutron backgrounds down to a negligible level. Resonance parameters and radiative kernels have been determined for 16 resonances by means of an R-matrix analysis in the neutron energy range from 3 keV to 320 keV. Good agreement with previous measurements was found at low neutron energies, whereas substantial discrepancies appear beyond 45 keV. With the present results, we obtain an s-process contribution of 77(8)% to the solar abundance of 207Pb. This corresponds to an r-process component of 23(8)%, which is important for deriving the U/Th ages of metal poor halo stars., 7 pages, 3 figures, to be published in Phys. Rev. C

Abstract: A series of neutron capture cross section measurements of interest to nuclear astrophysics have been recently performed at n_TOF, the neutron spallation source operating at CERN. The low repetition frequency of the proton beam driver, the extremely high instantaneous neutron flux, and the low background conditions in the experimental area are optimal for capture cross section measurements on low-mass or radioactive samples. An overview of the measurements performed during the two experimental campaigns in 2002 and 2003 is presented with special emphasis on the measurement of the capture cross sections of the Os isotopes relevant for the cosmochronology based on the Re/Os clock. http://www.sciencedirect.com/science/article/B6TVB-4GFTP27-40/1/e75becb4002b5a2d671901c2aa851543

Abstract: The 151 Sm(n, γ ) 152 Sm cross section, which is important for the interpretation of the 151 Sm branching as an s -process thermometer, was measured from 1 eV up to 1 MeV at the innovative n_TOF facility at CERN. Based on these data, the Maxwellian-averaged cross section at k T = 30 keV is found to be 3100±160 mb. This value can be used to constrain the thermodynamical conditions in Asymptotic Giant Branch (AGB) stars during He-shell burning.

Abstract: Neutron capture cross sections of the 90,91,92,94,96Zr have been measured over the energy range from 1 eV to 1 MeV at the spallation neutron facility n TOF at CERN in 2003. The innovative features of the neutron beam, in particular the high instantaneous flux, the high energy resolution and low background, together with improvements of the neutron sensitivity of the capture detectors make this facility unique for neutron-induced reaction cross section measurements with much improved accuracy. The preliminary results of the Zr measurements show capture resonance strengths generally smaller than in previous measurements.

270. Remittances and welfare in Tajikistan

Author: Herrera Martinez, Rodolfo Eduardo and Herrera Martinez, Rodolfo Eduardo
Abstract: In many developing countries, migration and remittances have become an important option for households facing poverty, unemployment and lack of opportunities. This raises the question of how effective this strategy is in improving welfare in countries sending migrants abroad and receiving remittances back. Of particular interest is the case of countries that have become highly dependent on the remittance income. Among them, Tajikistan registered the highest percentage of received remittances on the Gross Domestic Product in 2009, about 35%. This paper thus focuses on the evaluation of the remittance effect on three welfare indicators for Tajikistan in 2007: poverty, inequality, and schooling. This is done by estimating a contrafactual consumption aggregate for households in the hypothetical case they stop receiving remittances and re-calculating the poverty and inequality indicators. The effect of remittances on schooling is evaluated by estimating how receiving remittances in the household affect the probability of a child to be enrolled at school. The results point to a positive relationship between remittances and poverty reduction, but also a relationship with an increase in inequality. Remittances are found to be related to an increase in the likelihood of children aged 7 to 15 years to be enrolled at school, with a stronger effect for girls.

Abstract: In this paper, a perceptual audio compressor is developed with the use of the Wavelet Transform in an Embedded System. Former compressors were not able to achieve remarkable compression ratios while maintaining the same format type (in this case .wav). The present project makes an efficient use of a Transform which enables appropriate time-frequency tracking, without perceptual losses. As it is known, the FFT tracking is not suitable for the transient representation in audio signals, and signals containing highly variable spectral components from frame to frame. The present work addresses a more suitable representation with the use of the Daubechies-Wavelet Type 4, which solves satisfactorily the problem.

Abstract: En temas de seguridad y vigilancia es de interés poder reconocer vehículos por marca y modelo, los cuales pueden ser de utilidad en distintas formas según el sitio y su contexto. La clasificación por marca-modelo, se basa principalmente en la identificación de vehículos utilizando la captura de un área característica del mismo, que permita diferenciarlo de otros; esta área generalmente es: la parte frontal o la parte posterior del vehículo, aunque en ocasiones es una vista lateral. En trabajos previos se han abordado propuestas utilizando puntos de vista como: parte trasera, contorno, aproximación 3D, parte frontal o de lado. Este trabajo utiliza la parte frontal del vehículo como referencia/área de interés; para esto, en un ambiente uni-carril y/o multi-carril, donde en una imagen hay la posibilidad de múltiples vehículos, primero se localiza cada vehículo dentro de la toma. De ahí, para cada vehículo, se extrae la parrilla. Finalmente, la parrilla se utiliza como la referencia para encontrar características que clasifiquen a una parrilla con una marca y modelo. Por la naturaleza del ambiente no controlado, este trabajo se distingue por ser flexible a diferentes: resoluciones de imagen, iluminación, posición del vehículo y ángulo de toma. Los resultados de seis muestras tomados en tres distintos puntos de la zona metropolitana de Puebla, dieron 86% de aciertos de extracción de parrilla y la clasificación de Marca y Modelo de vehículos dio 89%.

Abstract: Introduction A recommended technique for a radiation therapy treatment for HL is a mantle field technique. This technique in most of the cases represents a challenge for the dose calculation not only for the irregularity and size of the field but for the anatomical area to cover; going from the neck to mediastinal region and in some cases up to the axillar regions, thus represents an important problem when the required dose distribution has to be uniform enough to achieve coverage suggested standards, especially for those anatomies with short neck and/or fat chests which leaded to an undesired hot spots on neck and chin mostly and their correspondent side effects. In order to avoid this and improved the treatment, since 2010, mantle techniques are treated with compensators observing improvements in the dose distribution obtained. Purpose To improved quality on mantle technique for HL diminishing side effects. Method Each of this treatment plans were calculated using the Varian Eclipse irregular surface compensator calculation technique and verified using gamma index criteria. Each plan were compared with the blocked field of the same size, shape and energy. Results and conclusions On the dosimetric comparisons we observed a hot spots from 5% to 12% lower than the observed with a conventional technique and an improved hot spot localization according to clinical criteria. Clinically, side effects expected according to experience with blocked fields were diminished on about 70% of the cases on a five years follow-up.

Abstract: The yield of the neutron capture reaction 232Th(n,γ) has been measured at the neutron time-of-flight facility n-TOF at CERN in the energy range from 1 eV to 1 MeV. The reduction of the acquired data to the capture yield for resolved resonances from 1 eV to 4 keV is described and compared to a recent evaluated data set. The resonance parameters were used to assign an orbital momentum to each resonance. A missing level estimator was used to extract the s-wave level spacing of D0=17.2±0.9 eV. © 2012 American Physical Society.

Abstract: A few years ago, the neutron time-of-flight facility n_TOF was built at CERN to address some of the urgent needs of high-accuracy nuclear data for Accelerator Driven Systems and other advanced nuclear energy systems, as well as for nuclear astrophysics and fundamental nuclear physics. Thanks to the characteristics of the neutron beam, and to state-of-the-art detection and acquisition systems, high quality neutron cross-section data have been obtained for a variety of isotopes, many of which radioactive. Following an important upgrade of the spallation target and of the experimental area, a new measurement campaign has started last year. After a brief review of the most important results obtained so far at n_TOF, the new features of the facility are presented, together with the first results on the commissioning of the neutron beam. The plans for future measurements, in particular related to nuclear technology are finally discussed.

Abstract: The (n,γ) cross section of 96Zr has been investigated at the CERN n-TOF spallation neutron source. High-resolution time-of-flight measurements using an enriched ZrO2 sample allowed us to analyze 15 resonances below 40 keV with improved accuracy. On average, the capture widths were found to be 25% smaller than reported in earlier experiments. If complemented with the contribution by direct radiative capture, the derived Maxwellian averaged cross sections are consistent with activation data at kT=25 keV. The present results confirm the astrophysical implications for the s-process branching at 95Zr. © 2011 American Physical Society.

Abstract: The neutron-induced fission cross section of {sup 236}U was measured at the neutron Time-of-Flight (n-TOF) facility at CERN relative to the standard {sup 235}U(n,f) cross section for neutron energies ranging from above thermal to several MeV. The measurement, covering the full range simultaneously, was performed with a fast ionization chamber, taking advantage of the high resolution of the n-TOF spectrometer. The n-TOF results confirm that the first resonance at 5.45 eV is largely overestimated in some nuclear data libraries. The resonance triplet around 1.2 keV was measured with high resolution and resonance parameters were determined with good accuracy. Resonances at high energy have also been observed and characterized and different values for the cross section are provided for the region between 10 keV and the fission threshold. The present work indicates various shortcomings of the current nuclear data libraries in the subthreshold region and provides the basis for an accurate re-evaluation of the {sup 236}U(n,f) cross section, which is of great relevance for the development of emerging or innovative nuclear reactor technologies.

Abstract: Neutron-induced fission cross-sections of minor actinides have been measured using the n_TOF white neutron source at CERN, Geneva, as part of a large experimental program aiming at collecting new data relevant for nuclear astrophysics and for the design of advanced reactor systems. The measurements at n_TOF take advantage of the innovative features of the n_TOF facility, namely the wide energy range, high instantaneous neutron flux and good energy resolution. Final results on the fission cross-section of 233U, 245Cm and 243Am from thermal to 20 MeV are here reported, together with preliminary results for 241Am. The measurement have been performed with a dedicated Fast Ionization Chamber (FIC), a fission fragment detector with a very high efficiency, relative to the very well known cross-section of 235U, measured simultaneously with the same detector.

Abstract: The neutron capture cross sections of the Zr isotopes play an important role in nucleosynthesis studies. The s-process reaction flow between the Fe seed and the heavier isotopes passes through the neutron magic nucleus {sup 90}Zr and through {sup 91,92,93,94}Zr, but only part of the flow extends to {sup 96}Zr because of the branching point at {sup 95}Zr. Apart from their effect on the s-process flow, the comparably small isotopic (n,{gamma}) cross sections make Zr also an interesting structural material for nuclear reactors. The {sup 94}Zr (n,{gamma}) cross section has been measured with high resolution at the spallation neutron source n{sub T}OF at CERN and resonance parameters are reported up to 60 keV neutron energy.

Abstract: Neutron-induced fission cross sections for {sup nat}Pb and {sup 209}Bi were measured with a white-spectrum neutron source at the CERN Neutron Time-of-Flight (n{sub T}OF) facility. The experiment, using neutrons from threshold up to 1 GeV, provides the first results for these nuclei above 200 MeV. The cross sections were measured relative to {sup 235}U and {sup 238}U in a dedicated fission chamber with parallel plate avalanche counter detectors. Results are compared with previous experimental data. Upgraded parametrizations of the cross sections are presented, from threshold energy up to 1 GeV. The proposed new sets of fitting parameters improve former results along the whole energy range.

Abstract: The cross section of the reaction 197Au(n,γ) was measured with the time-of-flight technique at the n_TOF (neutron time-of-flight) facility in the unresolved resonance region between 5 and 400 keV using a pair of C6D6 (where D denotes 2H) liquid scintillators for the detection of prompt capture γ rays. The results with a total uncertainty of 3.9%-6.7% for a resolution of 20 bins per energy decade show fair agreement with the Evaluated Nuclear Data File Version B-VII.0 (ENDF/B-VII.0), which contains the standard evaluation. The Maxwellian-averaged cross section (MACS) at 30 keV is in excellent agreement with the one according to the ENDF/B-VII.0 evaluation and 4.7% higher than the MACS measured independently by activation technique. Structures in the cross section, which had also been reported earlier, have been interpreted as being due to clusters of resonances.

Abstract: The neutron-induced fission cross-section of 233U has been measured at the CERN n_TOF facility relative to the standard fission cross-section of 235U between 0.5 and 20MeV. The experiment was performed with a fast ionization chamber for the detection of the fission fragments and to discriminate against \( \alpha\) -particles from the natural radioactivity of the samples. The high instantaneous flux and the low background of the n_TOF facility result in data with uncertainties of \( \approx\) 3% , which were found in good agreement with previous experiments. The high quality of the present results allows to improve the evaluation of the 233U (n,f) cross-section and, consequently, the design of energy systems based on the Th/U cycle.

Abstract: The (n,gamma) cross section of (96)Zr has been investigated at the CERN n_TOF spallation neutron source. High-resolution time-of-flight measurements using an enriched ZrO(2) sample allowed us to analyze 15 resonances below 40 keV with improved accuracy. On average, the capture widths were found to be 25% smaller than reported in earlier experiments. If complemented with the contribution by direct radiative capture, the derived Maxwellian averaged cross sections are consistent with activation data at kT = 25 keV. The present results confirm the astrophysical implications for the s-process branching at (95)Zr. Physical Review C
