Sample records for actinium 207

  1. Extraction of actinium with di-(2-ethylhexyl)phosphoric acid from hydrochloric and nitric acid solutions

    The extraction of actinium with HDEHP from Cl- and NO3- systems has been investigated. It was found that extraction of actinium from HCl solutions is much better than from HNO3 solutions. Stability constants of actinium complexes Ac(X-)+2 with Cl- and NO3- ligands were determined. Our results show that the actinium formed less stable complexes with Cl- than with NO3- ligands. 5 refs., 3 figs., 1 tab. (author)

  2. The sorption of polonium, actinium and protactinium onto geological materials

    This paper describes a combined experimental and modeling program of generic sorption studies to increase confidence in the performance assessment for a potential high-level radioactive waste repository in Japan. The sorption of polonium, actinium and protactinium onto geological materials has been investigated. Sorption of these radioelements onto bentonite, tuff and granodiorite from equilibrated de-ionized water was studied under reducing conditions at room temperature. In addition, the sorption of actinium and protactinium was investigated at 60 C. Thermodynamic chemical modeling was carried out to aid interpretation of the results

  3. Separation of Actinium 227 from the uranium minerals

    The purpose of this work was to separate Actinium 227, whose content is 18%, from the mineral carnotite found in Gomez Chihuahua mountain range in Mexico. The mineral before processing is is pre-concentrated and passed, first through anionic exchange resins, later the eluate obtained is passed through cationic resins. The resins were 20-50 MESH QOWEX and 100-200 MESH 50 X 8-20 in some cased 200-400 MESH AG 50W-X8, 1X8 in other cases. The eluates from the ionic exchange were electrodeposited on stainless steel polished disc cathode and platinum electrode as anode; under a current ODF 10mA for 2.5 to 5 hours and of 100mA for .5 of an hour. it was possible to identify the Actinium 227 by means of its descendents, TH-227 and RA-223, through alpha spectroscopy. Due to the radiochemical purity which the electro deposits were obtained the Actinium 227 was low and was not quantitatively determined. A large majority of the members of the natural radioactive series 3 were identified and even alpha energies reported in the literature with very low percentages of non-identified emissions were observed. We conclude that a more precise study is needed concerning ionic exchange and electrodeposit to obtain an Actinium 227 of radiochemical purity. (Author)

    Actinium-225 is a promising isotope for targeted-α therapy. Unfortunately, progress in developing chelators for medicinal applications has been hindered by a limited understanding of actinium chemistry. This knowledge gap is primarily associated with handling actinium, as it is highly radioactive and in short supply. Hence, Ac(III) reactivity is often inferred from the lanthanides and minor actinides (that is, Am, Cm), with limited success. Here we overcome these challenges and characterize actinium in HCl solutions using X-ray absorption spectroscopy and molecular dynamics density functional theory. The Ac-Cl and Ac-OH2O distances are measured to be 2.95(3) and 2.59(3) Å, respectively. The X-ray absorption spectroscopy comparisons between Ac(III) and Am(III) in HCl solutions indicate Ac(III) coordinates more inner-sphere Cl(1-) ligands (3.2±1.1) than Am(III) (0.8±0.3). These results imply diverse reactivity for the +3 actinides and highlight the unexpected and unique Ac(III) chemical behaviour. PMID:27531582

    Currently, 31 actinium, 31 thorium, 28 protactinium, and 23 uranium isotopes have so far been observed; the discovery of these isotopes is discussed. For each isotope a brief summary of the first refereed publication, including the production and identification method, is presented.

  6. Production of high-purity radium-223 from legacy actinium-beryllium neutron sources.

    2012-07-01

    Radium-223 is a short-lived alpha-particle-emitting radionuclide with potential applications in cancer treatment. Research to develop new radiopharmaceuticals employing (223)Ra has been hindered by poor availability due to the small quantities of parent actinium-227 available world-wide. The purpose of this study was to develop innovative and cost-effective methods to obtain high-purity (223)Ra from (227)Ac. We obtained (227)Ac from two surplus actinium-beryllium neutron generators. We retrieved the actinium/beryllium buttons from the sources and dissolved them in a sulfuric-nitric acid solution. A crude actinium solid was recovered from the solution by coprecipitation with thorium fluoride, leaving beryllium in solution. The crude actinium was purified to provide about 40 milligrams of actinium nitrate using anion exchange in methanol-water-nitric acid solution. The purified actinium was then used to generate high-purity (223)Ra. We extracted (223)Ra using anion exchange in a methanol-water-nitric acid solution. After the radium was separated, actinium and thorium were then eluted from the column and dried for interim storage. This single-pass separation produces high purity, carrier-free (223)Ra product, and does not disturb the (227)Ac/(227)Th equilibrium. A high purity, carrier-free (227)Th was also obtained from the actinium using a similar anion exchange in nitric acid. These methods enable efficient production of (223)Ra for research and new alpha-emitter radiopharmaceutical development. PMID:22697483

  7. Radium, thorium, and actinium extraction from seawater using an improved manganese-oxide-coated fiber

    Laboratory experiments were conducted to determine the efficiency with which improved manganese-oxide-coated acrylic fibers extract radium, thorium, and actinium from seawater. Tests were made using surface seawater spiked with 227Ac, 227Th and 223Ra. For sample volumes of approximately 30 liters and flow rates up to 0.5 liters per minute, radium and actinium are removed quantitatively. Approximately 80-95% of the thorium is removed under these same conditions. (Auth.)

  10. Production of Actinium-225 via High Energy Proton Induced Spallation of Thorium-232

    The science of cancer research is currently expanding its use of alpha particle emitting radioisotopes. Coupled with the discovery and proliferation of molecular species that seek out and attach to tumors, new therapy and diagnostics are being developed to enhance the treatment of cancer and other diseases. This latest technology is commonly referred to as Alpha Immunotherapy (AIT). Actinium-225/Bismuth-213 is a parent/daughter alpha-emitting radioisotope pair that is highly sought after because of the potential for treating numerous diseases and its ability to be chemically compatible with many known and widely used carrier molecules (such as monoclonal antibodies and proteins/peptides). Unfortunately, the worldwide supply of actinium-225 is limited to about 1,000mCi annually and most of that is currently spoken for, thus limiting the ability of this radioisotope pair to enter into research and subsequently clinical trials. The route proposed herein utilizes high energy protons to produce actinium-225 via spallation of a thorium-232 target. As part of previous R and D efforts carried out at Argonne National Laboratory recently in support of the proposed US FRIB facility, it was shown that a very effective production mechanism for actinium-225 is spallation of thorium-232 by high energy proton beams. The base-line simulation for the production rate of actinium-225 by this reaction mechanism is 8E12 atoms per second at 200 MeV proton beam energy with 50 g/cm2 thorium target and 100 kW beam power. An irradiation of one actinium-225 half-life (10 days) produces ∼100 Ci of actinium-225. For a given beam current the reaction cross section increases slightly with energy to about 400 MeV and then decreases slightly for beam energies in the several GeV regime. The object of this effort is to refine the simulations at proton beam energies of 400 MeV and above up to about 8 GeV. Once completed, the simulations will be experimentally verified using 400 MeV and 8 GeV protons

  15. Neutron-Induced Fission of Actinium-227, Protactinium-231 and Neptunium-237: Mass Distribution

    Results of radiochemical studies on the mass distribution in the neutron-induced fission of actinium-227, protactinium-231 and neptunium-237 have been presented. This work has been carried out as part of a programme to determine the mass distribution in the fission of heavy elements as a function of Z and A. All irradiations have been carried out in the core of the swimming-pool type reactor APSARA with cadmium shielding wherever necessary. Relative yields of several fission product nuclides have been obtained by a method involving a comparison of the fission product activities from the respective targets with those formed from uranium-235 simultaneously irradiated. Thermal-neutron fission yields of uranium-235 have been assumed. These results indicate a predominantly asymmetric mass distribution in all the three cases, and also a distinct though small symmetric peak in the case of actinium-227. (author)

  16. A new method for the determination of low-level actinium-227 in geological samples

    We developed a new method for the determination of 227Ac in geological samples. The method uses extraction chromatographic techniques and alpha-spectrometry and is applicable for a range of natural matrices. Here we report on the procedure and results of the analysis of water (fresh and seawater) and rock samples. Water samples were acidified and rock samples underwent total dissolution via acid leaching. A DGA (N,N,N',N'-tetra-n-octyldiglycolamide) extraction chromatographic column was used for the separation of actinium. The actinium fraction was prepared for alpha spectrometric measurement via cerium fluoride micro-precipitation. Recoveries of actinium in water samples were 80 ± 8 % (number of analyses n = 14) and in rock samples 70 ± 12 % (n = 30). The minimum detectable activities (MDA) were 0.017-0.5 Bq kg-1 for both matrices. Rock sample 227Ac activities ranged from 0.17 to 8.3 Bq kg-1 and water sample activities ranged from below MDA values to 14 Bq kg-1of 227Ac. From the analysis of several standard rock and water samples with the method we found very good agreement between our results and certified values. (author)

    Excited states in 207Rn are investigated via the 196Pt(16O,Sn)207Rn reaction at beam energies from 85 to 95 MeV using techniques of in-beam γ-ray spectroscopy. Measurements ofγ-ray excitation function, x - γ and γ - γ- t coincidences are performed with ten BGO(AC)HPGe detectors. Based on these measurements, a level scheme of207Rn, including 17 γ-rays and 18 levels, is established. Spins for most of the levels are proposed according to the measured DCO ratios. The level structure is compared with a weak-coupling calculation using the interaction energies extracted from neighbouring nuclei.

  2. In-source laser spectroscopy developments at TRILIS—towards spectroscopy on actinium and scandium

    Resonance Ionization Laser Ion Sources (RILIS) have become a versatile tool for production and study of exotic nuclides at Isotope Separator On-Line (ISOL) facilities such as ISAC at TRIUMF. The recent development and addition of a grating tuned spectroscopy laser to the TRIUMF RILIS solid state laser system allows for wide range spectral scans to investigate atomic structures on short lived isotopes, e.g., those from the element actinium, produced in uranium targets at ISAC. In addition, development of new and improved laser ionization schemes for rare isotope production at ISAC is ongoing. Here spectroscopic studies on bound states, Rydberg states and autoionizing (AI) resonances on scandium using the existing off-line capabilities are reported. These results allowed to identify a suitable ionization scheme for scandium via excitation into an autoionizing state at 58,104 cm − 1 which has subsequently been used for ionization of on-line produced exotic scandium isotopes.

    2016-06-01

    To study exotic nuclides at the borders of stability with laser ionization and spectroscopy techniques, highest efficiencies in combination with a high spectral resolution are required. These usually opposing requirements are reconciled by applying the in-gas-laser ionization and spectroscopy (IGLIS) technique in the supersonic gas jet produced by a de Laval nozzle installed at the exit of the stopping gas cell. Carrying out laser ionization in the low-temperature and low density supersonic gas jet eliminates pressure broadening, which will significantly improve the spectral resolution. This article presents the required modifications at the Leuven Isotope Separator On-Line (LISOL) facility that are needed for the first on-line studies of in-gas-jet laser spectroscopy. Different geometries for the gas outlet and extraction ion guides have been tested for their performance regarding the acceptance of laser ionized species as well as for their differential pumping capacities. The specifications and performance of the temporarily installed high repetition rate laser system, including a narrow bandwidth injection-locked Ti:sapphire laser, are discussed and first preliminary results on neutron-deficient actinium isotopes are presented indicating the high capability of this novel technique.

  2. Groundwater seepage from the Ranger uranium mine tailings dam: radioisotopes of radium, thorium and actinium. Supervising Scientist report 106

    Monitoring of bores near the Ranger uranium mine tailings dam has revealed deterioration in water quality in several bores since 1983. In a group of bores to the north of the dam, increases have been observed of up to 500 times for sulphate concentrations and of up to 5 times for 226Ra concentrations. Results are presented here of measurements of members of the uranium, thorium and actinium decay series in borewater samples collected between 1985 and 1993. In particular, measurements of all four naturally-occurring radium isotopes have been used in an investigation of the mechanism of radium concentration changes. For the most seepage-affected bores the major findings of the study include: 228Ra/226Ra 223Ra /226Ra and 224Ra/228Ra ratios all increased over the course of the study; barium concentrations show high seasonal variability, being lower in November than May, but strontium concentrations show a steady increase with time. Calculations show that the groundwater is probably saturated with respect to barite but not with respect to celestite or anglesite; sulphide concentrations are low in comparison with sulphate, and are higher in November than in May; and 227Ac concentrations have increased with time, but do not account for the high 223Ra/226Ra ratios. It is concluded on the basis of these observations that increases in Ra isotope concentrations observed in a number of seepage-affected bores arise from increases in salinity leading to desorption of radium from adsorption sites in the vicinity of the bore rather by direct transport of radium from the tailings. Increased salinity is also causing the observed increases in 227Ac and strontium concentrations, while formation of a barite solid phase in the groundwater is causing the removal of some radium from solution. This is the cause of the increasing radium isotope ratios noted above

    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.

  2. Search for the l-forbidden beta decay /sup 207/Tl→/sup 207/Pb(570 keV)

    We have searched for the l-forbidden beta decay of /sup 207/Tl to the first excited state of /sup 207/Pb by looking for 570-keV γ rays following the decay of /sup 207/Tl. We find a branching ratio of (2.4 +- 5.6) x 10/sup -7/ per /sup 207/Tl decay. This limit could provide a test for calculations of core polarization, meson exchange, and Δ excitation effects. We also find a branch of (0.54 +- 0.05)% for the l-forbidden M1 transition /sup 207/Pb(898,(3/2-→570,(5/2-) and measure the intensities of γ rays emitted following the decay of /sup 211/Pb

  3. Experiments of analog states on Lead 206 and 207

    This research thesis aims at verifying hypotheses according to which the spread of analog states decreases as much as nuclei are far from a double magic nucleus, under some conditions. Therefore, analog states of lead 207 and 208 have been studied by proton scattering on targets in lead 206 and 207. Some theoretical aspects of analog states of isobaric spin are presented. An experimental method of determination of excitation functions is described. Results obtained for analog states in bismuth 207-208 are discussed. Results obtained on four steady lead isotopes in different laboratories are compared

  6. Radiotherapy combined with Tegafur (FT-207s) for brain tumors

    5-Fluorouracil (5-FU) has anti-tumor effects as an anti-metabolite, but it cannot pass the Blood-Brain-Barrier (BBB). FT-207 a masked-compound of 5-FU, is easily lipid soluble and is able to pass the BBB. Twenty eight patients of primary brain tumor and 8 patients of metastatic brain tumor were treated with irradiation combined with 750 mg of FT-207 suppository. Twenty four patients of primary brain tumor were treated only with irradiation as control. The mean survival time was 20.4 +- 11.8 months for the combined therapy group and 17.6 +- 8.6 months for the control. The concentration of FT-207 and 5-FU in serum and in cerebrospinal fluid (CSF) was investigated after administration of 750 mg of FT-207 suppository per annum. The maximum concentration of FT-207 and of 5-FU in serum was 20.4 +- 11.8 mcg/ml and 0.06 +- 0.02 mcg/ml, respectively. There were observed several side effects, such as anorexia, nausea, exanthema and etc. These side effects were not so great as to interrupt the therapy at the dose level of 750 mg of FT-207. However, at the dose of 1500 mg, one case showed disturbance of consciousness, to which attention should be called. (author)

  4. NMR absolute shielding scale and nuclear magnetic dipole moment of (207)Pb.

    Adrjan, Bożena; Makulski, Włodzimierz; Jackowski, Karol; Demissie, Taye B; Ruud, Kenneth; Antušek, Andrej; Jaszuński, Michał

    2016-06-28

    An absolute shielding scale is proposed for (207)Pb nuclear magnetic resonance (NMR) spectroscopy. It is based on ab initio calculations performed on an isolated tetramethyllead Pb(CH3)4 molecule and the assignment of the experimental resonance frequency from the gas-phase NMR spectra of Pb(CH3)4, extrapolated to zero density of the buffer gas to obtain the result for an isolated molecule. The computed (207)Pb shielding constant is 10 790 ppm for the isolated molecule, leading to a shielding of 10799.7 ppm for liquid Pb(CH3)4 which is the accepted reference standard for (207)Pb NMR spectra. The new experimental and theoretical data are used to determine μ((207)Pb), the nuclear magnetic dipole moment of (207)Pb, by applying the standard relationship between NMR frequencies, shielding constants and nuclear moments of two nuclei in the same external magnetic field. Using the gas-phase (207)Pb and (reference) proton results and the theoretical value of the Pb shielding in Pb(CH3)4, we find μ((207)Pb) = 0.59064 μN. The analysis of new experimental and theoretical data obtained for the Pb(2+) ion in water solutions provides similar values of μ((207)Pb), in the range of 0.59000-0.59131 μN. PMID:27265668

  5. Core excitations across the neutron shell gap in 207Tl

    E. Wilson

    2015-07-01

    Full Text Available The single closed-neutron-shell, one proton–hole nucleus 207Tl was populated in deep-inelastic collisions of a 208Pb beam with a 208Pb target. The yrast and near-yrast level scheme has been established up to high excitation energy, comprising an octupole phonon state and a large number of core excited states. Based on shell-model calculations, all observed single core excitations were established to arise from the breaking of the N=126 neutron core. While the shell-model calculations correctly predict the ordering of these states, their energies are compressed at high spins. It is concluded that this compression is an intrinsic feature of shell-model calculations using two-body matrix elements developed for the description of two-body states, and that multiple core excitations need to be considered in order to accurately calculate the energy spacings of the predominantly three-quasiparticle states.

    2014-01-01

    目的:观察白癜风皮损中CD207的表达,探讨白癜风的免疫发病机制。方法采用免疫组织化学法检测12例节段型白癜风、25例寻常型白癜风和10例正常皮肤组织中CD207的表达水平,并比较其差异性。结果节段型白癜风组、寻常型白癜风组表皮内CD207表达分别为(61.2±10.9)和(64.3±12.5)个/mm,均高于正常对照组(52.4±10.3)个/mm,差异有统计学意义(P﹤0.05)。节段型白癜风组与寻常型白癜风组相比,CD207表达差异无统计学意义( P﹥0.05)。结论节段型白癜风、寻常型白癜风皮损组织中CD207的表达高于正常对照组,提示其发病机制与朗格汉斯细胞参与的细胞免疫反应有关。%Objective To observe the expression of CD207 in the lesions of vitiligo and the immune pathogenesis of vitiligo. Meth-ods The CD207 expression level was detected by immunohistochemistry in 12 patients with segmental vitiligo,25 patients with vitiligo vulgaris and 10 normal skin tissues,and the results were compared. Re-sults The expression of CD207 in segmental vitiligo group and vitiligo vulgaris group was(61. 2 ± 10. 9) and(64. 3 ± 12. 5)count/mm respectively,(52. 4 ± 10. 3)count/mm in control group. The differences were statistically significant( P﹤0. 05 ). Conclusions The expression of CD207 in the lesions of seg-mental vitiligo and vitiligo vulgaris is higher than that in the normal control group,indicating that the mechanism of vitiligo is associated with the cellular immunity response which langerhans cell was in-volved.

  15. Low-metallicity Young Clusters in the Outer Galaxy I. Sh 2-207

    Yasui, Chikako; Tokunaga, Alan T; Saito, Masao; Izumi, Natsuko

    2015-01-01

    To study star formation in low metallicity environments ([M/H] ~ -1 ,dex), we obtained deep near-infrared (NIR) images of Sh 2-207 (S207), which is an HII region in the outer Galaxy with spectroscopically determined metallicity of [O/H] ~= -0.8 dex. We identified a young cluster in the western region of S207 with a limiting magnitude of Ks =19.0 mag (10 sigma) that corresponds to a mass detection limit of <~0.1 M_sun and enables the comparison of star-forming properties under low metallicity with those of the solar neighborhood. From the fitting of the K-band luminosity function (KLF), the age and distance of S207 cluster are estimated at 2-3Myr and ~4 kpc, respectively. The estimated age is consistent with the suggestion of small extinctions of stars in the cluster (Av ~ 3 mag) and the non-detection of molecular clouds. The reasonably good fit between observed KLF and model KLF suggests that the underlying initial mass function (IMF) of the cluster down to the detection limit is not significantly differen...

  17. Study of 207Tl126 Produced in Deep-Inelastic Reactions

    Wilson E.

    2014-03-01

    Full Text Available Deep-inelastic collisions of a 208Pb beam on a 208Pb target were performed using the ATLAS accelerator at Argonne National Laboratory. The Gammasphere detector array was used for the detection of prompt and delayed gamma-rays of the reaction products.207Tl is one proton away from the 208Pb doubly-magic nucleus. Its low-energy level structure is dominated by the single proton-hole states πs1/2−1, πd3/2−1 and πh11/2−1. The 11/2− state is isomeric with T1/2 = 1.33(11 s. The reaction partner of 207Tl is 209Bi, which has arelatively well established level scheme compared to 207Tl. Cross-coincidences between these two nuclei were used to confirm or establish levels above the 11/2− isomeric state in 207Tl. These states are obtained via breaking of the neutron core. Angular correlation analysis was performed on known transitions in 208Pb, proving the applicability of this method for multipolarity assignment.

  3. Core breaking and octupole low-spin states in $^{207}$ Tl

    We propose to study the low-spin level structure of the $^{207}$Tl nucleus populated by the $\\beta$- decay of $^{207}$Hg. While $^{207}$Tl is a single-proton hole nucleus, the majority of the observed states will have threeparticle structure thus requiring the breaking of the neutron or proton core, or a collective octupole phonon coupled to the single proton hole. Thus information will be obtained on the single particle orbitals in the vicinity of the N=126 and Z=82 magic numbers, and on the size of the shell gap. The results will be used to improve the predictive power of the shell model for more exotic nuclei as we move to lighter N=126 nuclei.The experiment will use the ISOLDE Decay station, and will take advantage of the $^{207}$Hg beam from the molten lead target. A test on the feasibility to produce $^{208}$Hg beam from the same target, with the aim to study the $\\beta$-decay into $^{208}$Tl, could be performed at the same time.

  4. Study of 207Tl126 produced in deep-inelastic reactions

    Deep-inelastic collisions of a 208Pb beam on a 208Pb target were performed using the ATLAS accelerator at Argonne National Laboratory. The Gamma-sphere detector array was used for the detection of prompt and delayed gamma-rays of the reaction products. 207Tl is one proton away from the 208Pb doubly-magic nucleus. Its low-energy level structure is dominated by the single proton-hole states πs(1/2)-1, πd(3/2)-1 and πh(11/2)-1. The (11/2)- state is isomeric with T1/2= 1.33(11) s. The reaction partner of 207Tl is 209Bi, which has a relatively well established level scheme compared to 207Tl. Cross-coincidences between these two nuclei were used to confirm or establish levels above the (11/2)- isomeric state in 207Tl. These states are obtained via the breaking of the neutron core. Angular correlation analysis was performed on known transitions in 208Pb, proving the applicability of this method for multipolarity assignment. (authors)

  7. Sterilizing activity of second-line regimens containing TMC207 in a murine model of tuberculosis.

    Nicolas Veziris

    Full Text Available RATIONALE: The sterilizing activity of the regimen used to treat multidrug resistant tuberculosis (MDR TB has not been studied in a mouse model. OBJECTIVE AND METHODS: Swiss mice were intravenously inoculated with 6 log10 of Mycobacterium tuberculosis (TB strain H37Rv, treated with second-line drug combinations with or without the diarylquinoline TMC207, and then followed without treatment for 3 more months to determine relapse rates (modified Cornell model. MEASUREMENTS: Bactericidal efficacy was assessed by quantitative lung colony-forming unit (CFU counts. Sterilizing efficacy was assessed by measuring bacteriological relapse rates 3 months after the end of treatment. MAIN RESULTS: The relapse rate observed after 12 months treatment with the WHO recommended MDR TB regimen (amikacin, ethionamide, pyrazinamide and moxifloxacin was equivalent to the relapse rate observed after 6 months treatment with the recommended drug susceptible TB regimen (rifampin, isoniazid and pyrazinamide. When TMC207 was added to this MDR TB regimen, the treatment duration needed to reach the same relapse rate dropped to 6 months. A similar relapse rate was also obtained with a 6-month completely oral regimen including TMC207, moxifloxacin and pyrazinamide but excluding both amikacin and ethionamide. CONCLUSIONS: In this murine model the duration of the WHO MDR TB treatment could be reduced to 12 months instead of the recommended 18-24 months. The inclusion of TMC207 in the WHO MDR TB treatment regimen has the potential to further shorten the treatment duration and at the same time to simplify treatment by eliminating the need to include an injectable aminoglycoside.

  8. IL-17A is not expressed by CD207+ cells in Langerhans Cell Histiocytosis lesions

    Allen, Carl E.; McClain, Kenneth L.

    2009-01-01

    Interleukin-17 (IL-17A) is a pro-inflammatory cytokine that has recently been implicated in pathogenesis of Langerhans Cell Histiocytosis (LCH), a potentially fatal disease characterized by lesions including CD207+ (langerin +) histiocytes. However, in this study we were unable to identify IL-17A gene expression in Langerhans cell lesions, and plasma levels of IL-17A did not correlate with disease activity. Therefore, this study does not support a central role for IL-17A in LCH pathogenesis.

  9. Analisis Film Horor Indonesia Produksi Tahun 2014 (Studi Kasus: Mall Klender dan Kamar 207

    2016-02-01

    Full Text Available Abstrak Film horor erat kaitannya dengan tokoh antagonis yang menimbulkan ketakutan pada penonton dalam bentuk makhluk supranatural seperti hantu, roh jahat dan sebagainya. Karakteristik film dengan genre horor membuat penonton terbawa suasana dengan alur ceritanya yang menakutkan. Namun, beberapa dari film horor Indonesia menyajikan adegan-adegan yang kurang sopan bahkan tergolong asusila atau porno. Untuk itu, penelitian ini ingin melihat apakah terdapat konten pornografi pada film Mall Klender dan Kamar 207 yang merupakan film horor Indonesia terlaris di tahun 2014. Analisis dilakukan dengan melihat pandangan dan penilaian 30 responden dengan karakteristik yaitu penonton film horor Indonesia yang berusia 20-40 tahun. Berdasarkan hasil analisis, tidak didapatkan konten pornografi pada film Mall Klender dan Kamar 207. Adegan-adegan yang terindikasi sebagai konten pornografi ternyata masih dapat diterima oleh penonton sebagai adegan yang berada dalam batas kewajaran dan mendukung pembawaan suasana dan kesan dalam cerita yang disampaikan. Kata Kunci: film horror Indonesia, analisis konten, pornografi Abstract The horror film is closely related to the antagonist that causes fear for audience in the form of supernatural creatures such as ghosts, demons and so on. Characteristic of the horor film is to make the audience carried away with the scary plot. However, some of the existing Indonesian horror film presents scenes that classified as obscene or pornographic. Therefore, this study wanted to see if there are any pornographic content on the film Klender Mall and Room 207 is the best-selling Indonesian horror movie in 2014. The analysis was done by looking at the view and assessment of 30 respondents which are Indonesian horror movie goers aged 20-40 years. Based on the analysis, there is no founding of pornographic content on the film Klender Mall and Room 207. The scenes that indicated as pornographic content was still acceptable by the audience

  10. Concentrations of 207Bi and 210Pb-210Bi-210Po disequilibrium in fish

    Radioactive 207Bi, produced during nuclear testing at the Pacific Proving Grounds, concentrates in the muscle tissue and organs of goatfish and certain pelagic lagoon fish from Bikini and Enewetak Atolls. It is reasonable to expect that fish capable of accumulating 207Bi could also be efficient accumulators of other bismuth isotopes - namely 210Bi, the daughter of naturally occurring 210Pb. Therefore, 210Bi and consequently 210Po, the decay product of 210Bi, would be expected in notable excess over the precursor 210Pb in specific tissues. To test this assumption, we compared concentrations of 210Pb, 210Bi, and 210Po in muscle, liver, and bone separated from some reef species from the Marshall Islands. Concentrations of 210Bi in muscle and liver were found to exceed those of its precursor by factors of 2 to 15. The excess 210Bi in some species, however, is not from the environmental sources (either food or water) from which 207Bi is derived. The data suggest that the excess 210Bi may be translocated to muscle and liver tissue following the decay of 210Pb in bone

  11. NanoSIMS 207Pb-206Pb dating of monazite, xenotime and baddeleyite

    Verdel, C.; Mahan, K.; Guan, Y.; Eiler, J.; Wernicke, B.

    2007-12-01

    A variety of geochronological problems call for in-situ dating with high spatial resolution (i.e., scales of tens of microns or less). Such techniques are particularly important for studies that focus on the relationships between intracrystalline age variations and petrologic or diagenetic processes. Precise, in-situ geochronology of particularly small grains or domains (ca. 1-5 microns) may be feasible with the Cameca NanoSIMS ion microprobe, which has a spatial resolution as good as tens of nanometers and sufficient mass resolution at high transmission to be useful for geochronologic systems involving isotopes of trace elements. We have used the Cameca NanoSIMS 50L housed in the Caltech Microanalysis Center to determine 207Pb/206Pb ages of monazite, xenotime and baddeleyite standards ranging in age from ~500 to 2000 Ma. Initial efforts focused on Pb-Pb geochronology because it is analytically straightforward: Pb is ionized almost entirely to Pb+ and instrumental mass fractionation of Pb isotopes is negligible. We compare our results to previous age determinations made on these standards using TIMS, SHRIMP and electron microprobe techniques. Our NanoSIMS 207Pb/206Pb age of 2047±35 Ma (2σ) for a baddeleyite crystal from the Phalaborwa carbonatite overlaps with the previously determined TIMS and SHRIMP dates of ca. 2060 Ma. We measured an age of 1018±20 Ma on xenotime standard x6413, slightly older than the TIMS 207Pb/206Pb date of 996.7±0.8 Ma. For the high-Th Moacyr monazite standard, variations of common-Pb corrected ages and 206Pb/204Pb ratios for 5 measurements spanning ~100 microns suggest varying amounts of interference from a mass-204 isobar (probably doubly ionized ThNdO2). The single measurement least-affected by this isobar corresponds to a common-Pb corrected 207Pb/206Pb age of 489±92 Ma, within error of the electron microprobe chemical age of ca. 505 Ma. Spatial variation of the mass-204 isobar intensity suggests that Th may be distributed

  12. A suggested search for 207Pb nuclear Schiff moment in PbTiO3 ferroelectric

    Mukhamedjanov, T N

    2004-01-01

    We suggest two types of experiments, NMR and macroscopic magnetometry, with solid PbTiO3 to search for the nuclear Schiff moment of 207Pb. Both kinds of experiments promise substantial improvement over the presently achieved sensitivities. Statistical considerations show that the improvement of the current sensitivity can be up to 10 orders of magnitude for the magnetometry experiment. Such significant enhancement is due to the strong internal electric field of the ferroelectric, as well as due to the possibility to cool the nuclear-spin subsystem in the compound down to nanokelvin temperatures.

  13. CP-MAS 207Pb with 19F decoupling NMR spectroscopy: medium range investigation in fluoride materials.

    Bureau, B; Silly, G; Buzaré, J Y

    1999-11-01

    The isotropic chemical shift of 207Pb is used to perform structural investigations of crystalline fluoride compounds (PbF2, Pb2ZnF6, PbGaF5, Pb3Ga2F12 and Pb9Ga2F24) and transition metal fluoride glasses (TMFG) of the PZG family (PbF2-ZnF2-GaF3). Using 207Pb Cross Polarisation Magic Angle Spinning (CP-MAS) NMR with 19F decoupling, it is shown that the isotropic chemical shift of 207Pb varies on a large scale (1000 ppm) and that the main changes of its value are not due to the nearest neighbour fluorines but may be related to the number of next nearest neighbour (nnn) Pb2+ ions. In this way, it is demonstrated that 207Pb chemical shift is an interesting probe to investigate medium range order in either crystalline or glassy fluoride systems. The 207Pb delta(iso) parameter has been linearly correlated to the number of nnn Pb2+ ions. PMID:10670899

    1982-10-01

    A combination therapy consisting of daily intrarectal administration of 1,500 mg of FT-207 suppository, daily or every three day bladder instillation of 40 mg adriamycin for a total of 20 applications, and once per week intramuscular administration of 5 KE OK-432 was described. The therapy was performed in 30 cases of advanced bladder cancer. The effectiveness evaluated by Karnofsky's criteria was as follows: 8 cases of 0-0, 2 of 0-A, 1 of 0-B, 2 of 0-C, 7 of 1-A and 10 of 1-B, showing an effective rate of 57%. Local pain was observed in 20 cases (67%), pancytopenia in 1 (3%), hepatitis in 4 (13%), stomatitis in 5 (17%) and anorexia in 6 (20%). From this clinical trial, it is presumed that combination therapy administering FT-207 intrarectally, adriamycin intravesically and OK-432 intramuscularly might be used for the treatment of advanced bladder cancer provided sufficient care is taken of general side effects.

    The ROSEBUD Collaboration has dedicated several underground runs to study different types of bolometers, mainly for the search of dark matter. Some of these runs, profiting from the good energy resolution of one bolometer of BGO and the ultra-low background of the underground laboratory of Canfranc (LSC), allowed the measurement of the L/K electron capture ratio of the {sup 207}Bi decay to the 1633 keV level of {sup 207}Pb. This paper constitutes the first published measurement of this magnitude. (orig.)

  16. Interactions of 160 GeV/Nucleon $^{207}$Pb Nuclei in Emulsion Chambers with Copper and Lead Targets

    1998-04-01

    The reaction of PbCl{sub 2} with LiN(PPh{sub 2}){sub 2} (1) at -78 C affords the P-P coupled phosphazene Ph{sub 2}P-N=PPh{sub 2}-PPh{sub 2}=N-PPH{sub 2} (2) as an oxidation product and, as a reduction equivalent, the novel lead(1+) complex [(Pb{sup +1}){sub 2}({mu}Ph{sub 2}P-N-PPh{sub 2}{sup -}){sub 2}](Pb-Pb) (3). The crystal structure determination of the red compound 3 shows a Pb-Pb bond length of 304.1(1) pm. The {sup 31}P- and {sup 207}Pb-NMR spectra of 3 are complicated due to the presence of a higher order spin system (AA`A``A```X for the mono-{sup 207}Pb isotopomer, AA`A``A```X` for the bis-{sup 207}Pb isotopomer). Simulations of the {sup 31}Pb and {sup 207}Pb spectra both on material with natural isotope abundance and on the {sup 207}Pb-labelled compound (3*) reveal a large Pb, Pb coupling constant of 7708 Hz, indicative of a covalent Pb-Pb bond. - Through InCl{sub 3} is diagnonally related to PbCl{sub 2}, no significant redox process is observed in the reaction between InCl{sub 3} and 1. The yellow crystal of [In{sup 3+}(Ph{sub 2}P-N-PPh{sub 2}{sup -}){sub 3}] (4) that are obtained were also investigated by X-ray analysis. These show a propeller-like configuration of the three four-membered chelate rings with indium(3+) as the centre. (orig.)

  9. First direct observation of bound-state beta-decay: Measurements of branching and lifetime of 207Tl81+ fragments

    The first experimental observation of bound-state beta-decay showed, that due solely to the electron stripping, a stable nuclide, e.g. 163Dy, became unstable. Also a drastic modification of the half-life of bare 187Re, from 4.12(2) x 1010 years down to 32.9(20) years, could be observed. It was mainly due to the possibility for the mother nuclide to decay into a previously inaccessible nuclear level of the daughter nuclide. It was proposed to study a nuclide where this decay mode was competing with continuum-state beta-decay, in order to measure their respective branchings. The ratio βb/βc could also be evaluated for the first time. 207Tl was chosen due to its high atomic number, and Q-value of about 1.4 MeV, small enough to enhance the βb probability and large enough to allow the use of time-resolved Schottky Mass Spectrometry (SMS) to study the evolution of mother and bound-state beta-decay daughter ions. The decay properties of the ground state and isomeric state of 207Tl81+ have been investigated at the GSI accelerator facility in two separate experiments. For the first time β-decay where the electron could go either to a bound state (atomic orbitals) and lead to 207Pb81+ as a daughter nuclide, or to a continuum state and lead to 207Pb82+, has been observed. The respective branchings of these two processes could be measured as well. The deduced total nuclear half-life of 255(17) s for 207Tl81+, was slightly modified with respect to the half-life of the neutral atom of 286(2) s. It was nevertheless in very good agreement with calculations based on the assumption that the beta-decay was following an allowed type of transition. The branching βb/βc=0.192(20), was also in very good agreement with the same calculations. The application of stochastic precooling allowed to observe in addition the 1348 keV short-lived isomeric state of 207Tl. The half-life of this isomeric state was measured as 1.47(32) s, which shows a small deviation compared to the half-life for

    Several subsets of dendritic cells (DCs) are present in the oropharyngeal tonsillar tissues and are thought to behave as major actors in development and regulation of immunity by acting as a first line of recognition for airborne and alimentary antigens. We previously discovered in human adult tonsils infected with Epstein–Barr virus (EBV), a subset of DCs that expressed langerin/CD207, a lectin usually recognized as a hallmark of epidermal Langerhans cells (LCs). In the present study, we analyzed the content of several child and adult tonsils in order to characterize in more detail the phenotype of these tonsillar CD207-expressing DCs (tCD207 DCs) and to compare it with that of other human DC subsets. We showed that all the human tonsils studied (n = 12) contained significant proportions of tCD207 DCs among tonsillar cells expressing HLA-DR. Moreover, the presence of tCD207 DCs in tonsils from young children free of EBV infection indicated that these cells could be established early in the tonsil independently of EBV infection. We also showed that tCD207 DCs, that were found mainly located within the tonsillar lymphoid stroma, were distinguishable from LCs by the level of expression of CD1a and EpCAM, and also from human inflammatory DCs by the lack of CD1a, CD206, and CD14 expression. Detailed analysis of cell surface DC markers showed that tCD207 DCs were unrelated to CD141+ DCs or macrophages, but defined a subtype of tonsillar DCs closely related to myeloid resident CD1c DCs. Since it was established that blood CD1c myeloid DCs exhibit plasticity and are capable of expressing CD207 notably in the presence of inflammatory cytokines, it is tempting to speculate that CD207+ CD1c+ DCs may play a specific immune role.

Methods A total of 430 patients diagnosed with metabolic syndrome in 2008completed questionnaire and before randomly assigned to the health management group ( n = 207 ) and the control group (n=223). One year later, all the participants were investigated for the risk factors of food intake, cigarette smoking, alcohol consumption, staying-up and emotion, and the changes of body mass index ( BMI), blood pressure ( BP), triglyceride (TG), high-density lipoprotein cholesterol (HDL) and fasting blood glucose (FBG). Student's t test and x2 test were used for data analysis. Results For the health management group, the incidence of high-salt, high-fat and high-sugar intake, overtake of food, lack of physical exercises,staying-up and alcohol drinking was significantly decreased at 1 year (P < 0. 05 ), when compared with baseline and the control group ( both P < 0. 05 ). For the health management group, BMI,systolic blood pressure (SBP),TG and FBG was improved at 1 year (P<0. 05). In comparison with the control group, BMI, SBP, diastolic blood pressure (DBP),TG and FBG of the management group were significantly improved (P < 0. 05 ). Conclusions Patients with metabolic syndrome may have better treatment compliance after receiving systematized and individualized health management.%目的 通过对武汉市某单位职工代谢综合征的健康管理效果观察,对比分析健康管理对于相关危险因素的发生率及代谢综合征相关指标的影响.方法 将2008年某单位体检中诊断为代谢综合征430例患者,通过问卷调查收集的健康信息进行健康风险因素分析;通过随机分组将207例自愿参与健康管理者作为管理组,管理组给予系统化的健康管理,其余223例作为对照组,仅给予一般性的健康指导及建议,一年后通过再次体检及问卷调查结果对比分析饮食、吸烟

  12. Neutron total cross sections of 204Pb, 206Pb, 207Pb and 208Pb and the neutron electric polarizability

    The neutron total cross sections have been measured for lead isotopes 208Pb, 206Pb and 207Pb in the range from 1 eV to 20 keV and for 204Pb in the range from 1 eV to 100 eV using the time-of-flight facility GNEIS in Gatchina. An accuracy of the measured neutron total cross section (Δσ/σ) is about 10-3 for 208Pb, 10-2 for 206Pb and 207Pb, 5·10-2 for 204Pb. An estimated value of the neutron electric polarizability from analysis of total cross section of 208Pb is αn=(2.4 ± 1.1)·10-3fm3. (author)

  13. The separation of 65Zn from 113Sn and 207Bi radioisotopes by amalgam exchange and electro-analytical methods

    In this study, by using amalgam-exchange and electro-analytical methods, the separation of 65Zn radioisotope from a solution containing either one or both of the 113Sn and 207Bi radioisotopes were investigated. The radioisotopes were drawn into Zn-amalgam from the solution at first, and then 65Zn was recovered from the amalgam through back-electrolysis. No detectable contamination was observed and the recovery efficiency was found to be around 75%. (author)

  14. Energy resolution for gamma-rays and electrons from 207Bi in liquid Xe doped with TEA

    The energy resolution for γ-rays and conversion electrons electrons from 207 Bi has been studied by using a liquid xenon ionization chamber doped with photoionizing dopant TEA. Althought a significant improvement in the resolution is found at a low electric field by doping with TEA, improvement at a high electric field was not observed in marked contrast to a 'δ-ray recombination model'.

    2016-01-01

    G 207-9 and LP 133-144 are two rarely observed ZZ Ceti stars located in the middle and close to the blue edge of the ZZ Ceti instability domain, respectively. We aimed to observe them at least during one observing season at Konkoly Observatory with the purpose of extending the list of known pulsation modes for asteroseismic investigations and detect any significant changes in their pulsational behaviour. We determined five and three new normal modes of G 207-9 and LP 133-144, respectively. In LP 133-144, our frequency analysis also revealed that at least at three modes there are actually triplets with frequency separations of ~4 microHz. The rotational period of LP 133-144 based on the triplets is ~42 h. The preliminary asteroseismic fits of G 207-9 predict Teff=12 000 or 12 400 K and M*=0.855-0.870 MSun values for the effective temperature and mass of the star, depending on the assumptions on the spherical degree (l) values of the modes. These results are in agreement with the spectroscopic determinations. I...

    Fried, I; Erickson, P; Schwartz, S; Keenan, K

    1996-01-01

    This study investigated the epidemiology, sequelae, and prognosis of subluxation injuries to the maxillary primary anterior dentition. Data were collected from dental records at the Montreal Children's Hospital, Montreal, Canada, of patients sustaining trauma between 1982 and 1993. The study group consisted of 207 teeth in 134 patients, 81 males and 53 females. The age of the patients ranged from 0.8 years to 7.5 years, with a mean of 3.5 years. The highest incidence of trauma was in males between the ages of 3 and 4 years, and in females between 1 and 3 years. The highest incidence of trauma (66.2%) involved the primary central incisors. The most common cause of trauma (52%) was simple falls indoors. Occlusal or periapical radiographs were the radiographic view of choice unless an anterior nasal spine fracture was suspected, in which case a lateral projection was exposed. Approximately 64% of the study teeth had a mobility ranging from 0.6 to 1.5 mm. Treatment varied from no treatment (80% of teeth) to extraction. Post-traumatic evaluations were distributed into six common time intervals used by dentists for follow up. The results indicated that patient discomfort and occlusal interference were not common. Discoloration and pulpal calcification increased with time. Mobility decreased with time, with the majority of teeth returning to a normal physiologic range. External resorption may have been present, but was rare. Treatment or antibiotics were rarely needed at follow-up visits. Overall, these teeth responded positively, and there was a low morbidity associated with subluxation injuries. PMID:8710718

  17. Detection of lead via lead-207m using cyclic activation and a modified sum-coincidence system

    Samples containing lead were irradiated in a reactor, counted on a detector, and the process repeated for an optimum number of cycles in order to determine the concentration of the element present. The 0.8s isomer of /sup 207m/Pb was detected using two 7.5 cm x 7.5 cm NaI (Tl) crystals operating in a modified sum-coincidence system. The efficiency and resolution of the system were measured using a standard source. The sensitivity and detection limits for lead in various matrices of environmental interest were obtained. The sensitivity in an interference free matrix was found to be 5 μg

    Full Text Available Betulinic acid (BA, a pentacyclic triterpene, represents a new therapeutic substance that has potential benefits for treating glioblastoma. Recently, new strategies for producing BA derivatives with improved properties have evolved. However, few studies have examined the combination of BA or BA derivatives using radiotherapy. The effects of two BA derivatives, NVX-207 and B10, on cellular and radiobiological behavior were analyzed using glioblastoma cell lines (U251MG, U343MG and LN229. Based on IC50 values under normoxic conditions, we detected a 1.3–2.9-fold higher cytotoxicity of the BA derivatives B10 and NVX-207, respectively, compared to BA. Incubation using both BA derivatives led to decreased cell migration, cleavage of PARP and decreased protein expression levels of Survivin. Weak radiation sensitivity enhancement was observed in U251MG cells after treatment with both BA derivatives. The enhancement factors at an irradiation dose of 6 Gy after treatment with 5 µM NVX-207 and 5 µM B10 were 1.32 (p = 0.029 and 1.55 (p = 0.002, respectively. In contrast to BA, neither NVX-207 nor B10 had additional effects under hypoxic conditions. Our results suggest that the BA derivatives NVX-207 and B10 improve the effects of radiotherapy on human malignant glioma cells, particularly under normoxic conditions.

  1. 2psub(1/2) and 2psub(3/2) proton states of sup(207)Tl

    Recent experimental results on the deep proton hole states of sup(207)Tl indicate the presence of 2psub(1/2) and 2psub(3/2) states within the excitation region of 3.8 to 14.5 MeV. An entire distribution of these two deep hole states is obtained through the hole-core vibrational scheme after obtaining the zero order shell model energies of these two hole states from the numerical solution of the Schroedinger equation. The renormalized shell model energies of the entire proton hole states so far known from the latest experiments can be used to obtain the proton magicity in the super heavy region.

    The clinical course of infection with Mycobacterium leprae varies widely and depends on the pattern of the host immune response. Dendritic cells play an important role in the activation of the innate and adaptive immune system and seem to be essential for the development of the disease. To analyze the presence of epidermal dendritic cells (CD1a and CD207), plasmacytoid dendritic cells (CD123) and dermal dendrocytes (factor XIIIa) in lesion fragments of leprosy patients, skin samples from 30 patients were studied. These samples were submitted to immunohistochemistry against CD1a, CD207, FXIIIa, and CD123. The results showed a larger number of Langerhans cells, detected with the CD1a or CD207 marker, dermal dendrocytes and plasmacytoid dendritic cells in patients with the tuberculoid form. A positive correlation was observed between the Langerhans cell markers CD1a and CD207 in both the tuberculoid and lepromatous forms, and between Langerhans cells and dermal dendrocytes in samples with the tuberculoid form. The present results indicate the existence of a larger number of dendritic cells in patients at the resistant pole of the disease (tuberculoid) and suggest that the different dendritic cells studied play a role, favoring an efficient immune response against infection with M. leprae.

    2015-01-01

    Full Text Available Thomas R Whisenhunt Jr, Kiran F Rajneesh, James R Hackney, James M Markert Department of Neurosurgery, University of Alabama at Birmingham, Birmingham, AL, USA Background: Glioblastoma multiforme (GBM is a relentless primary central nervous system malignancy that remains resistant to conventional therapy despite major advances in clinical neurooncology. This report details the case of a patient who had failed conventional treatment for recurrent GBM and was ultimately treated with a genetically engineered herpes simplex virus (HSV type 1 vector, G207. Methods: Case report detailing the outcomes of one patient enrolled into the gene therapy arm of the Neurovir G207 protocol whereby stereotactic injection of 120 µL G207 viral suspension containing 1×107 plaque-forming units (or active viral particles was made into the enhancing region of the tumor. Results: In this patient, despite aggressive surgical resection, adjuvant radiotherapy and chemotherapy, tumor progression occurred. However, with G207 oncolytic therapy and brief exposures to second and third treatments, this patient had an extended survival time of 7.5 years and a 6-year apparent disease-free interval, an extraordinarily unusual finding in the pretemozolomide era. Conclusion: With minimal adjunctive chemotherapy, including one course of temozolomide, one course of procarbazine, and four cycles of irinotecan, the patient survived over 7 years before the next recurrence. Addition of G207 to this patient’s traditional therapy may have been the critical treatment producing her prolonged survival. This report demonstrates the potential for long-term response to a one-time treatment with oncolytic HSV and encourages continued research on oncolytic viral therapy for GBM.

    Atopic dermatitis (AD) is an allergic inflammatory disease of skin. It remains unclear that CD207 of Langerhans cells (LCs) plays a central role in the development of allergic sensitization. There is little data on LCs within the microenviroment in vivo. We used a murine model of epicutaneous (EC) ovalbumin (OVA) sensitization inducing an inflammatory skin resembling AD to explore the role of CD207 in the pathogenesis of AD. Cr:forsterite laser-based multimodality nonlinear microscopy was applied for in situ imaging. Peritoneal injections of Alexa Fluor 647-rat anti-mouse CD207 into mice were performed to specifically trace the LCs. Peritoneal injections of OVA-Alexa Fluor 647 conjugate into mice were performed to specifically trace the OVA. We found that combining Alexa Fluor fluorescent probes with multimodality nonlinear microscopy permitted the unequivocal in situ imaging of CD207-expressing LCs. The relevant time-course, expressional, and functional studies reveal that CD207 of LCs plays an essential role during the induction of EC sensitization. We establish and validate that Cr:forsterite laser-based multimodality nonlinear microscopy is applicable for the specific detection of labeled mAb-bound LCs and labeled antigen. We suggest that CD207-expressing LCs initiate the allergic response through the CD207 mediated epicutaneous sensitization associated with the development of AD.

  8. First direct observation of bound-state beta-decay. Measurements of branching and lifetime of {sup 207}Tl{sup 81+} fragments

    Boutin, D.

    2005-08-01

    The first experimental observation of bound-state beta-decay showed, that due solely to the electron stripping, a stable nuclide, e.g. {sup 163}Dy, became unstable. Also a drastic modification of the half-life of bare {sup 187}Re, from 4.12(2) x 10{sup 10} years down to 32.9(20) years, could be observed. It was mainly due to the possibility for the mother nuclide to decay into a previously inaccessible nuclear level of the daughter nuclide. It was proposed to study a nuclide where this decay mode was competing with continuum-state beta-decay, in order to measure their respective branchings. The ratio {beta}{sub b}/{beta}{sub c} could also be evaluated for the first time. {sup 207}Tl was chosen due to its high atomic number, and Q-value of about 1.4 MeV, small enough to enhance the {beta}{sub b} probability and large enough to allow the use of time-resolved Schottky Mass Spectrometry (SMS) to study the evolution of mother and bound-state beta-decay daughter ions. The decay properties of the ground state and isomeric state of {sup 207}Tl{sup 81+} have been investigated at the GSI accelerator facility in two separate experiments. For the first time {beta}-decay where the electron could go either to a bound state (atomic orbitals) and lead to {sup 207}Pb{sup 81+} as a daughter nuclide, or to a continuum state and lead to {sup 207}Pb{sup 82+}, has been observed. The respective branchings of these two processes could be measured as well. The deduced total nuclear half-life of 255(17) s for {sup 207}Tl{sup 81+}, was slightly modified with respect to the half-life of the neutral atom of 286(2) s. It was nevertheless in very good agreement with calculations based on the assumption that the beta-decay was following an allowed type of transition. The branching {beta}{sub b}/{beta}{sub c}=0.192(20), was also in very good agreement with the same calculations. The application of stochastic precooling allowed to observe in addition the 1348 keV short-lived isomeric state of {sup

  9. Liptinite as an indicator of environmental changes during formation of coal seam No. 207 (Upper Silesia, Poland)

    2007-08-01

    The coal seam No. 207 was a subject of palynological and petrographic studies. According to the results of the vitrinite random reflectance measurements supplemented by moisture and calorific value determinations, the rank of this coal is matching the boundary between sub-bituminous and bituminous coals. The aim was to reconstruct the environmental conditions during the biochemical stage of seam formation, as well as the facies development throughout the seam profile. The maceral (incident and fluorescence mode) and microlithotype compositions (incident light) supplemented by palynological analyses, show that there were two main facies developments. In the authors opinion, they correspond with a phase of ombrogenous, raised bog marked by the presence of crassidurite with Densosporites variabilis and a wet-forest swamp phase represented by vitrite and clarite with more diverse spore assemblage including densospores. Other minor but distinctive sediments, a cannel layer and a reeds facies, both occurring in the lower part of the seam. Above the tonstein horizon, a dry forest type of sedimentation is recognized.

    We present Lya luminosity function (LF), clustering measurements, and Lya line profiles based on the largest sample, to date, of 207 Lya emitters (LAEs) at z=6.6 on the 1 deg^2 sky of Subaru/XMM-Newton Deep Survey (SXDS) field. Our z=6.6 Lya LF including cosmic variance estimates yields the best-fit Schechter parameters of phi*=8.5 +3.0/-2.2 x10^(-4) Mpc^(-3) and L*(Lya)=4.4 +/-0.6 x10^42 erg s^(-1) with a fixed alpha=-1.5, and indicates a decrease from z=5.7 at the >~90% confidence level. However, this decrease is not large, only =~30% in Lya luminosity, which is too small to be identified in the previous studies. A clustering signal of z=6.6 LAEs is detected for the first time. We obtain the correlation length of r_0=2-4 h^(-1) Mpc and bias of b=3-5, and find no significant boost of clustering amplitude by reionization at z=6.6. The average hosting dark halo mass inferred from clustering is 10^10-10^11 Mo, and duty cycle of LAE population is roughly ~1% albeit with large uncertainties. The average of our hi...

  11. Determination of 206/207Pb isotope ratios by ICP-MS in particulate matter from the North Sea environment

    The determination of lead isotope ratios can be used for source and pathway characterization of lead in the environment. The suitability of inductively coupled mass spectrometry (ICP-MS) was evaluated for the measurement of 206/207Pb isotope ratios in several marine compartments as marine aerosols from different source regions and suspended particulate matter from the North Sea. Two different ICP-MS systems were used to carry out these investigations. First optimization studies have been performed to yield a sufficient precision (RSD<0.5%) incombination with a reasonable measuring time. This study has been carried out using the standard reference material NBS 981 with certified lead isotope ratios. Furthermore, it could be shown for marine environmental samples, that a precision of less than 0.5% RSD is attainable for counting rates of above approximately 50000 cps. As the following measurements of lead isotope ratios in marine aerosols from main source regions surrounding the North Sea demonstrated, this precision is sufficient to determine significant differences due to the origin of atmospheric lead. The analysis of aerosol samples revealed isotope ratios varying from as low as 1.10, which is close to that ratio for leaded gasoline in Europe to near background (modern lead) values of 1.20. The lead isotope ratios for the investigated suspended particulate matter ranges between 1.13 and 1.18. These values can be related to the solid discharge, the urban density and anthropogenic activity of the drainage basin. (orig.)

  12. Ion microprobe 207Pb/206Pb zircon ages for gneiss-granitoid rocks from Bundelkhand massif: evidence for Archaean components

    Radiometric 207Pb/206Pb ages of individual zircons from the Bundelkhand massif, central India, have been determined by an ion microprobe. Samples from various major litho-units, viz. the granite gneiss, hornblende-, biotite- and leuco-granitoid are included in this study. The results provide evidence for the presence of Archaean crustal components within this massif. Zircons with ages of 3.0 to 3.2 Ga occur as xenocrysts in a sample of granite gneiss from Lalitpur having a minimum formation age of 2.5 Ga. Another sample of a highly deformed gneiss from Babina has a well-defined age of 2.7 Ga. Emplacement of hornblende-granitoid and biotite-granitoid took place in quick succession at ∼ 2.5 Ga. No firm age for the youngest plutonic component, the leuco-granitoid, could be obtained due to poor recovery of zircons suitable for analysis. The geochronological data confirm the suggestion, based on geochemical studies, that the gneisses and the granitoids in this region represent Archaean and post-Archaean components respectively.

  13. Moessbauer study of the sintered Mn0.70Zn0.23Fe2.07O4

    The samples of Mn-Zn ferrite having characteristic of low power expense, were obtained. Its structure and phase transformation in pre-sintering process by means of Moessbauer spectroscopy were studied. The conclusions are as follows: (1) The sample sintered at high temperature contains excess iron, has the typical Moessbauer parameters. Its formula can be written as Mn0.70Zn0.23Fe2.07O4. (2) The doublet sub-spectrum arise during thermal transformation varies with the process of the phase transformation. It serves as a mark of the course of the transformation. (3) The pre-sintering temperature 1040 degree C has primarily approached to the earlier stage of phase transformation to form Mn-Zn ferrite. (4) The breaks in heating and pre-sintering repeatedly at low temperature are unfavourable to phase transformation. (5) the Moessbauer parameters of the raw material Fe2O3 are markedly different from that in literature. There is obvious influence on the samples pre-sintered but little influence on the sample sintered at high temperature

  15. Vector and tensor analyzing powers in the 208Pb(vector d,t)207Pb reaction at 200 and 360 MeV

    Cross-sections, vector and tensor analyzing powers for the main levels in 207Pb have been measured via the 208Pb (d,t) 207Pb reaction at 200 and 360 MeV incident energies. Ay and Ayy spin observables allow a clear identification of the valence levels, especially at 200 MeV. The results are compared with finite range DWBA calculations using the Paris projectile-ejectile form factor including the S and D components. The analysis shows a large effect of the D component on the tensor analyzing powers at the most forward angles. At both energies, the spin part of the deuteron optical potential is very important to describe the analyzing powers and especially Ayy. The good description of all observables at 200 MeV allows this reaction to be used as a spectroscopic tool

    The increasing emergence of carbapenem-resistant Acinetobacter spp. worldwide has resulted in the limited availability of effective antimicrobial agents and has become a major public health concern. In this study, the draft genome sequence of Acinetobacter pittii TCM292 belonging to sequence type 207 (ST207), a multidrug-resistant (MDR) isolate harbouring the New Delhi metallo-β-lactamase blaNDM-1 gene, was determined using an Illumina HiSeq™ 2000 platform. The genome sequence was analysed by bioinformatics methods. The A. pittii TCM292 genome size was estimated to be 3791758bp with 3486 predicted coding regions. These data might facilitate further understanding of the specific genomic features of MDR A. pittii in China. PMID:27530847

    1999-01-01

    The selectivity of ligands specific for certain cells can be used to preferentially target chemotherapeutic compounds to neoplastic cells. Human breast, ovarian, endometrial, and prostatic cancers express receptors that can mediate the delivery of targeted cytotoxic compounds to neoplastic cells. Recently, a potent derivative of 2-pyrrolinodoxorubicin (AN-201) conjugated to [d-Lys6] luteinizing hormone-releasing hormone (LH-RH) (AN-207), was demonstrated to be less toxic than the nonconjugate...

    Energies of 8410.1 ± 0.4, 20743.9 ± 0.3, and 63121.6 ± 1.2 eV were determined for the 8.4 keV M1 + E2, 20.7 keV M1 + E2, and 63.1 keV E1 nuclear transitions in {sup 169}Tm (generated in the EC decay of {sup 169}Yb), respectively, by means of the internal conversion electron spectroscopy. The {sup 169}Yb sources used were prepared by vacuum evaporation deposition on polycrystalline carbon and platinum foils as well as by ion implantation at 30keV into a polycrystalline aluminum foil. The relevant conversion electron spectra were measured by a high-resolution combined electrostatic electron spectrometer at 7 eV instrumental resoluition. Values of 0.0326(14) and 0.0259(17) were derived from our experimental data for the E2 admixture parameter δ (E2/M1) for the 8.4 and 20.7 keV transitions, respectively. A possible effect of nuclear structure on multipolarity of the 20.7 keV transition was also investigated. (orig.)

  20. 207-nm UV light - a promising tool for safe low-cost reduction of surgical site infections. I: in vitro studies.

    Manuela Buonanno

    Full Text Available BACKGROUND: 0.5% to 10% of clean surgeries result in surgical-site infections, and attempts to reduce this rate have had limited success. Germicidal UV lamps, with a broad wavelength spectrum from 200 to 400 nm are an effective bactericidal option against drug-resistant and drug-sensitive bacteria, but represent a health hazard to patient and staff. By contrast, because of its limited penetration, ~200 nm far-UVC light is predicted to be effective in killing bacteria, but without the human health hazards to skin and eyes associated with conventional germicidal UV exposure. AIMS: The aim of this work was to test the biophysically-based hypothesis that ~200 nm UV light is significantly cytotoxic to bacteria, but minimally cytotoxic or mutagenic to human cells either isolated or within tissues. METHODS: A Kr-Br excimer lamp was used, which produces 207-nm UV light, with a filter to remove higher-wavelength components. Comparisons were made with results from a conventional broad spectrum 254-nm UV germicidal lamp. First, cell inactivation vs. UV fluence data were generated for methicillin-resistant S. aureus (MRSA bacteria and also for normal human fibroblasts. Second, yields of the main UV-associated pre-mutagenic DNA lesions (cyclobutane pyrimidine dimers and 6-4 photoproducts were measured, for both UV radiations incident on 3-D human skin tissue. RESULTS: We found that 207-nm UV light kills MRSA efficiently but, unlike conventional germicidal UV lamps, produces little cell killing in human cells. In a 3-D human skin model, 207-nm UV light produced almost no pre-mutagenic UV-associated DNA lesions, in contrast to significant yields induced by a conventional germicidal UV lamp. CONCLUSIONS: As predicted based on biophysical considerations, 207-nm light kills bacteria efficiently but does not appear to be significantly cytotoxic or mutagenic to human cells. Used appropriately, 207-nm light may have the potential for safely and inexpensively

    Objective To observe the efficacy and adverse reactions of iron supplementation for preventing iron deficiency anemia of mild low birth weight infants at different ages, to provide reference for the prevention of iron deficiency anemia in low birth weight infant. Methods Totally 207 mild low birth weight infants were divided into 3 experimental groups (groupⅠ:starting iron supplement from the age of 2 weeks;groupⅡ:starting iron sup-plement from the age of 4 weeks; groupⅢ: starting iron supplement from the age of 2 months) and one control group (groupⅣ:without iron supplement) basing on the principle of parent informed consent. The iron supplement was 2 mg·kg-1·d-1 for subjects in the three experimental groups. Performed blood cell analysis of all subjects respec-tively at the beginning, age of 3 months and 6 months, compared the HGB, MCV, MCH, MCHC and anemia incidence rate of each group. Occurrence of adverse reaction were monitored at the same time. Results The hemoglobin levels of groupⅠ,ⅡandⅢwere higher than that of groupⅣ, and the incidence rates of groupⅠ,ⅡandⅢwere lower than that of the groupⅣ. The differences were statistically significant (P0.05);there were no statistically significant differences between the hemoglobin levels and anemia incidence rates of groupⅠand groupⅡ(P>0.05);GroupⅠshowed most adverse reactions. Conclusion It would be better to start iron sup-plementation at the age of 4 weeks so as to prevent iron deficiency anemia in mild low birth weight infants. Earlier iron supplementation will increase the incidence of adverse reaction, while later iron supplementation will increase the incidence of anemia.%目的:观察不同时期开始补铁以预防轻度低出生体重儿缺铁性贫血的疗效及不良反应发生情况,为预防低出生体重儿缺铁性贫血提供参考。方法将207例轻度低出生体重儿按家长知情同意原则分为三个实验组(Ⅰ组从2周龄

    Objectives To understand the influence of measles vaccination on clinical manifestations of measles in children, different characteristics of measles in infants and children in order to improve early diagnosis of measles by analyzing the characteristics of measles cases with laboratory confirmed etiological data. Methods Clinical data were collected from children who visited the Department of Outpatient Infectious Diseases and hospitalized with clinical diagnosis of measles and confirmed by measles specific IgM and measles virus N gene fragment from January 2002 to December 2010. Measles specific IgM antibodies were tested using serum samples with ELISA. Measles virus N gene fragment was amplified from specimens of throat swabs and fresh urine by reverse transcription-polymerase chain reaction ( RT-PCR ). Analyses were performed in vaccinated and unvaccinated cased separately. Results ① In total, 207 cases of measles in children with etiological diagnosis were analyzed, including 123 males and 84 females, 53 vaccinated and 154 unvaccinated. Age distribution ranged from 0 to 15 years, including 69 cases ( 33. 3% ) of younger than 8 months ( who had not reached the age for primary measles vaccination ), and 45 cases ( 21. 7% ) of younger than 1 year of age. ②Cases with Beijing local residency was more common in vaccinated group than that in unvaccinated group. The peak incidence was found in April for all cases in two groups. 15.4% ( 24/154 ) cases with known exposure history in measles unvaccinated group and in unvaccinated group and 16. 9% ( 9/53 ) in measles vaccinated group, with no significant difference between two groups. ③The proportions of measles with symptoms of mucosa spots ( Koplik spots ) and cough were significantly lower in vaccinated group than in unvaccinated group while the other symptoms had no significant difference betweentwo groups. ④ Of 154 unvaccinated cases, 97 were younger than 1 and 57 older than 1 year old. Symptoms of eyes was

  3. Epidermoid carcinomas of the floor of mouth treated by exclusive irradiation: statistical study of a series of 207 cases

    Purpose. Our aim was to study the results and the complications of this series of 207 patients treated from 1976 to 1992 and to compare them with the results of the literature. Material and methods. The treatment consisted of a combination of external beam irradiation (EBI) (to the tumor and the node areas) and complementary brachytherapy to the primary tumor in 105 cases. In 102 cases, brachytherapy only was delivered to the tumor with or without neck dissection of the node areas. The brachytherapy was performed mostly with the hairpin technique in the beginning (in 61 cases) and subsequently the plastic tube technique with iridium wires. The dosimetry followed the Paris system rules. There were 41% T1, 48% T2, 8% T3, 2% T4 and 1% Tx with 83% N0, 12% N1, 3% N2, 2% N3. Ninety-one percent of patients were male and 9% were female. Results. The local control at 5 years is 97, 72 and 51%, respectively, for T1, T2, T3. The specific survival (without the patients dead of intercurrent disease or second cancer) was 88, 47 and 36%, and the overall survival at 5 years was 71, 42 and 35%. Of note, approximately one third of patients died of intercurrent disease or second cancers (70 patients = 34%). Significant factors that can influence the results are: for local control, the size of the lesion T1/T2/T3 (p < 0.0001); for the locoregional control, the absence of node involvement. The following factors are not significant: age and sex (age significant for survival). The significant treatment factors are the safety margin (p < 0.0003), brachytherapy only on T for T2N0 (p = 0.01). A total duration of treatment of less than 50 days is also significant. The spacing and the total dose (higher dose for large tumors) were not found to be significant. The complications were classified into four grades: grade 1, 17% (median healing, 2 months for soft tissue complications and 5 months for bone complications); grade 2, 12%; grade 3, 6% (frequently requiring surgical resection); grade 4

  4. Completion Report for Well ER-20-7: Corrective Action Units 101 and 102: Central and Western Pahute Mesa

    NSTec Environmental Restoration

    2010-04-28

    Well ER-20-7 was drilled for the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office in support of the Nevada Environmental Restoration Project at the Nevada Test Site, Nye County, Nevada. The well was drilled in June 2009 as part of the Pahute Mesa Phase II drilling program. The primary purpose of the well was to further investigate migration of radionuclides from the nearby, up-gradient TYBO and BENHAM underground nuclear tests, which originally was discovered at Well Cluster ER-20-5. This well also provided detailed hydrogeologic information in the Tertiary volcanic section that will reduce uncertainties within the Pahute Mesa-Oasis Valley hydrostratigraphic framework model. The main 44.45-centimeter hole was drilled to a depth of 681.8 meters and cased with 33.97-centimeter casing to 671.7 meters. The hole diameter was then decreased to 31.12 centimeters, and the well was drilled to total depth of 894.9 meters. The completion string, set to the depth of 890.0 meters, consists of 14.13-centimeter stainless-steel casing hanging from 19.37-centimeter carbon-steel casing. The 14.13-centimeter stainless-steel casing has one continuous slotted interval open to the Topopah Spring aquifer. Data collected during and shortly after hole construction include composite drill cuttings samples collected every 3.0 meters, sidewall core samples from 20 depth intervals, various geophysical logs, water quality (primarily tritium) measurements, and water level measurements. The well penetrated 894.9 meters of Tertiary volcanic rock, including two saturated welded-tuff aquifers. A fluid level measurement was obtained during open-hole geophysical well logging for the upper, Tiva Canyon, aquifer at the depth of 615.7 meters on June 19, 2009. The fluid level measured in the open hole on June 27, 2009,after the total depth was reached and the upper aquifer was cased off, was also at the depth of 615.7 meters. Preliminary field measurements indicated 1

  5. Status of the NEXT Ion Thruster Long-Duration Test After 10,100 hr and 207 kg Demonstrated

    2008-01-01

    The NASA s Evolutionary Xenon Thruster (NEXT) program is developing the next-generation ion propulsion system with significant enhancements beyond the state-of-the-art in ion propulsion to provide future NASA science missions with enhanced mission capabilities at a low total development cost. As part of a comprehensive thruster service life assessment utilizing both testing and analyses, a Long-Duration Test (LDT) was initiated to validate and qualify the NEXT propellant throughput capability to a qualification-level of 450 kg, 1.5 times the mission-derived throughput requirement of 300 kg. This wear test is being conducted with a modified, flight-representative NEXT engineering model ion thruster, designated EM3. As of June 21, 2007, the thruster has accumulated 10,100 hr of operation at the thruster full-input-power of 6.9 kW with 3.52 A beam current and 1800 V beam power supply voltage. The thruster has processed 207 kg of xenon and demonstrated a total impulse of 8.5 106 N-s; the highest total impulse ever demonstrated by an ion thruster in the history of space propulsion. Thruster performance tests are conducted periodically over the entire NEXT throttle table with input power ranging 0.5 to 6.9 kW. Overall ion thruster performance parameters including thrust, input power, specific impulse, and thruster efficiency have been nominal with little variation to date. Lifetime-limiting component erosion rates have been consistent with the NEXT service life assessment, which predicts the earliest failure sometime after 750 kg of xenon propellant throughput; well beyond the mission-derived lifetime requirement. The NEXT wear test data confirm that the erosion of the discharge keeper orifice, enlarging of nominal-current-density accelerator grid aperture cusps, and the decrease in cold grid-gap observed during the NSTAR Extended Life Test have been mitigated. This paper presents the status of the NEXT LDT to date.

  6. Investigation of the wave functions of low-lying states in 208Pb by the elastic and inelastic scattering of polarized protons from 207Pb

    The excitation functions of the differential cross section and the analyzing power of the scattering 207Pb(anti p, p') were measured in an energy range from 13.5 to 18 MeV at THETAlab = 1400 and 1600. By analyzing the elastic scattering 38 of in this range appearing isobar analog resonances (IAR) in 208 Bi were identified and their spins determined. The partly hypothetical spin relations out of literature for the states in the parent nucleus 208Pb had to be corrected in many cases. (orig.)

    The 2-year follow-up results for a randomized placebo-controlled study of 47 patients with multidrug-resistant pulmonary tuberculosis treated with either the new diarylquinoline TMC207, recently renamed bedaquiline, or placebo, added to the first 8 weeks of a background regimen, are presented. Bedaquiline significantly reduced the time to culture conversion over 24 weeks (hazard ratio, 2.253; 95% confidence interval, 1.08 to 4.71; P = 0.031). With the exception of nausea reported in 26% of pa...

  10. Spectroscopic study of 206,207,208Pb isotopes by high resolution analysis of 24.5 MeV proton scattering

    206,207,208pb have been studied by 24.5 MeV proton inelastic scattering with a resolution of 20 keV. The angular distributions of the differential cross-sections corresponding to the different excited levels have been measured in a large angular region and analysed with the DWBA.This work shows that it exists between 4 and 5 MeV of excitation energy some strongly excited levels corresponding to transfer momenta l = 2, 4, 6 and 8. The single particle-hole models do not explain these states; so it will probably be necessary to introduce some several particle - hole configurations. (author)

  11. Radical Rearrangement Catalysis in an Enzyme at 190-207 K: Mechanistic Features Revealed by Substrate ^1H/^2H Isotope Effects

    Zhu, Chen; Warncke, Kurt

    2009-11-01

    The decay kinetics of both the natural abundance and [1,1,2,2-^2H4]-aminoethanol generated Co^II-substrate radical pair catalytic intermediate in ethanolamine ammonia-lyase (EAL) from Salmonella typhimrium have been measured by using time-resolved, full-spectrum X-band continuous-wave electron paramagnetic resonance (EPR) spectroscopy in frozen aqueous solution from 190 to 207 K. The decay reaction proceeds through sequential radical covalent rearrangement and hydrogen atom transfer (HT) steps. In the temperature range from 190 to 207 K, the decay is biexponential, and the two phases correspond to distinct populations [1]. The ^1H/^2H isotope effects (IE) on the fast phase and slow phase are 1.3 and 0.8, respectively. These IE are not caused by a primary kinetic IE. Therefore, HT is rapid, relative to rearrangement. We propose that the fast phase is rate-determined by the rearrangement step, and that the slow phase is rate-determined by a step after rearrangement that is associated with protein guidance of the reactions. The results reveal microscopic features of the core reaction chemistry and protein dynamics participation in the reaction, which are not accessible at ambient temperatures.[4pt] [1] Zhu, C., Warncke, K.

    Full Text Available The novel exopolysaccharide HZ-7 is produced by Klebsiella sp. H-207, and its fermentation conditions were optimized by response surface methodology (RSM. In this study, the optimized medium consisted of sucrose 31.93 g/L, KNO(3 2.17 g/L and K(2HPO(4 5.47 g/L; while the optimized culture conditions consisted of seed age 13 h, with an inoculum size of 10.6% and incubation temperature of 28.9°C. A maximum HZ-7 yield of about 15.05 g/L was achieved under the optimized conditions using RSM and single-factor experiments. Next the exopolysaccharide HZ-7 was partially purified and characterized. The resulting product showed good properties, such as high concentration of uronic acid (41.67%, low average molecular weight (about 1.94×10(5 Da and porous surface structure, were very advantageous to biosorption. Therefore HZ-7 was applied to absorb hexavalent chromium (Cr(VI. The maximum adsorption efficiency (99.2% which was obtained at an initial pH of 1.0 along with an initial Cr(VI concentration of 20 mg/L, was not affected by ordinary metal ions and temperature. These data suggest Klebsiella sp. H-207 exopolysaccharide will be promising potential for industrial application.

  13. Characterization of the ground X1 state of 204Pb19F, 206Pb19F, 207Pb19F, and 208Pb19F

    Pure rotational spectra of the ground electronic-vibrational X1 state of 204Pb19F, 206Pb19F, 207Pb19F, and 208Pb19F are measured with a resonator pulsed supersonic jet Fourier-transform microwave spectrometer. Also reported is a new measurement of the Stark effect on the optical spectra of A(leftarrow)X1 transitions. These spectra are combined with published high-resolution infrared spectra of X2↔X1 transitions in order to create a complete picture of the ground state of lead monofluoride. For the microwave data, molecules are prepared by laser ablation of lead target rods and stabilized in a supersonic jet of neon mixed with sulfur hexafluoride. For the optical Stark spectra, a continuous source of molecules is created in a nozzle heated to 1000 deg. C. The microwave spectra confirm, improve, and extend previously reported constants that describe the rotational, spin-orbit, and hyperfine interactions of the ground electronic state of the PbF molecule. A discrepancy concerning the sign of the hyperfine constant describing the 207Pb nucleus is discussed. Magnetic-field-dependent microwave spectra are used to characterize the Zeeman interaction in terms of two g factors of the body-fixed electronic wave function. The optical Stark spectra are used to characterize the electric dipole moment of the X1 and A states.

  14. Developments of 207Pb, 208Pb and 209Bi target wheels in the synthesis of 107Ns, 108Hs and 109Mt

    The developments of 207Pb, 208Pb and 209Bi target wheels and their applications in heavy-ion fusion reactions are reviewed. In both, fabrication and use, the centers of the evaporator or accelerator beams are focussed at wheel radii of 155 mm to specially shaped frames which generate very homogeneous target layers and very constant reaction and counting rates in the experiment. Target areas of up to ∼98% of a wheel's circumference of 974 mm can be provided. The preparation procedures for necessary C backings and protecting layers of C are described, and details are given for the developments of high-vacuum evaporations of 207Pb, 208Pb and 209Bi with deposition yields of 35-55% from tantalum crucibles. The applications of the target wheels in heavy-ion fusion reactions with beams of 54Cr and 58Fe at energies near the Coulomb barrier and intensities of ∼1012 particles/s are mentioned. The target parameters for the production runs of the new chemical elements 107Ns, 108Hs and 109Mt are included. (orig.)

  15. Uptake of 207Pb and 111Cd through bark of mature sugar maple, white ash and white pine: a field experiment

    Cd and Pb uptake by bark is not likely to be a major contribution to metal burdens in tree xylem. - A field study was undertaken to determine whether 207Pb and 111Cd, applied to the exterior bark of sugar maple (Acer saccharum Marsh.), white ash (Fraxinus americana L.) and white pine (Pinus strobus L.), could enter xylem tissue. Stable isotope tracers (3 μg Pb ml-1; 2 μg Cd ml-1) were applied separately to bark in simulated rainfall, acidified to pH 4.5, in multiple doses over a 4 month (July-October) period. Tree cores were extracted from the region of application in the following March, and Pb and Cd isotopes were measured in bark and the outer tree rings using inductively coupled plasma mass spectrometry. The majority of the applied stable isotope tracer recovered (over 94%) was present in bark tissue, although a small amount of each metal tracer entered the outer (1-3) tree rings in all trees. Despite high concentrations of excess 207Pb in bark (up to 50 μg g-1), the maximum concentration of excess 207Pb measured in tree rings was only around 50 ng g-1, which represents less than 30% of the background Pb concentration in wood at the study site. High excess 111Cd concentrations in bark (up to 35 μg g-1) also resulted in small increases in 111Cd in wood (up to 50 ng g-1), but due to lower background Cd concentrations in wood, such increases more than doubled the amount of Cd in wood compared with background levels. However, at sites where such high bark Cd concentrations are found, uptake from Cd-contaminated soil would probably be much greater than found at our study site. It appears that Cd and Pb applied to bark can enter woody tissue, but that this route of uptake is likely to be a minor contributor to the metal burden in wood

  16. Chemical-shift tensors of heavy nuclei in network solids: a DFT/ZORA investigation of (207)Pb chemical-shift tensors using the bond-valence method.

    Alkan, Fahri; Dybowski, C

    2015-10-14

    Cluster models are used in calculation of (207)Pb NMR magnetic-shielding parameters of α-PbO, β-PbO, Pb3O4, Pb2SnO4, PbF2, PbCl2, PbBr2, PbClOH, PbBrOH, PbIOH, PbSiO3, and Pb3(PO4)2. We examine the effects of cluster size, method of termination of the cluster, charge on the cluster, introduction of exact exchange, and relativistic effects on calculation of magnetic-shielding tensors with density functional theory. Proper termination of the cluster for a network solid, including approximations such as compensation of charge by the bond-valence (BV) method, is essential to provide results that agree with experiment. The inclusion of relativistic effects at the spin-orbit level for such heavy nuclei is an essential factor in achieving agreement with experiment. PMID:26345261

  17. An investigation of cooling flows and general cluster properties from an X-ray image deprojection analysis of 207 clusters of galaxies

    White, D A; Forman, W R

    1997-01-01

    We present an X-ray image deprojection analysis of Einstein Observatory imaging data on 207, clusters of galaxies. The resulting radial profiles for luminosity, temperature, and electron density variations are determined from the cluster surface-brightness profiles according to gravitational potential constraints from average Tx and Vopt observations. This enables us to determine cooling-flow and other cluster properties, such as baryon fractions, S-Z microwave decrements, and Thomson depths. We have compiled a catalogue of the detected cooling flows, and investigated their effects on general cluster properties. Self-consistent correlations between the cluster X-ray luminosity, temperature, and optical velocity-dispersion, are determined accounting for errors in both dimensions of the data. These fits indicate that the temperatures of clusters are isothermal and that they have spectral beta-values consistent with unity. We find that the X-ray Lx, Tx, and optical Vopt relations depend significantly on the cool...

  18. A new organic metal with mixed anion: β-(ET)2(IBr2)0.7(I3)0.3. Synthesis, structure, properties

    Crystals β-(ET)2(IBr2)0.7(I3)0.3 (1) were prepared by oxidation of bis(ethylenedithio)tetrathiafulvalene (ET) by solution of IBr in nitrobenzene at 100 deg C with subsequent slow cooling of the reactive mixture. Compound 1 was studied by the methods of X-ray diffraction analysis at 293 and 130 K, differential scanning calorimetry in the range of 115-463 K and conductometry in the range of 0-300 K. It was ascertained that the compound prepared in terms of its structure and character of conductivity anisotropy variation in the range of 100-300 K is similar to β-(ET)2IBr2. At 135 K the order-disorder type phase transition is observed for compound 1, its enthalpy being equal to 3.3 J/mg

  20. Source identification of Pb in aerosols at Jeju-do, Korea by using 207Pb/206Pb and 208Pb/206Pb

    Aerosols and source related materials (fly ash from refuse incinerators, vehicle exhaust and soil) were collected in April, 2002 in the northern areas of Jeju-do, Korea, and the Pb isotopic ratios (207Pb/206Pb and 208Pb/206Pb) of the samples were measured in order to estimate the Pb sources of the aerosols. The Pb isotopic ratios of the aerosols were classified into two groups, depending on the sampling date. One group showed similar Pb isotopic ratios with those of the source related materials, suggesting that the contribution of the regional sources to the aerosols was very large. The other showed different Pb isotopic ratios from those of the regional sources and relatively high Pb isotopic ratios compared to the ratios of the first group. The results suggest that in the continental Asia there seems to be a long range transport of Pb with high ratios in desert sands, which are carried by northwest seasonal winds.(author)

    The work is aimed at experimental determination of the independent and cumulative yields of radioactive residual nuclei produced in intermediate-energy proton-irradiated thin targets made of highly isotopic enriched and natural lead (206,207,208,natPb) and 209Bi. 5972 radioactive product nuclide yields have been measured in 55 thin targets induced by 0.04, 0.07, 0.10, 0.15, 0.25, 0.6, 0.8, 1.2, 1.4, 1.6 and 2.6 GeV protons extracted from the ITEP U-10 proton synchrotron. The measured data have been compared with data obtained at other laboratories as well as with theoretical simulations by seven codes. We found that the predictive power of the tested codes is different but is satisfactory for most of the nuclides in the spallation region, though none of the codes agree well with the data in the whole mass region of product nuclides and all should be improved further.

  2. Pahute Mesa Well Development and Testing Analyses for Wells ER-20-7, ER-20-8 #2, and ER-EC-11, Revision 1

    Greg Ruskauff

    2011-12-01

    This report analyzes the following data collected from ER-20-7, ER-20-8 No.2, and ER-EC-11 during WDT operations: (1) Chemical indicators of well development (Section 2.0); (2) Static hydraulic head (Section 3.0); (3) Radiochemistry and geochemistry (Section 4.0); (4) Drawdown observed at locations distal to the pumping well (Section 5.0); and (5) Drilling water production, flow logs, and temperature logs (Section 6.0). The new data are further considered with respect to existing data as to how they enhance or change interpretations of groundwater flow and transport, and an interim small-scale conceptual model is also developed and compared to Phase I concepts. The purpose of well development is to remove drilling fluids and drilling-associated fines from the formation adjacent to a well so samples reflecting ambient groundwater water quality can be collected, and to restore hydraulic properties near the well bore. Drilling fluids can contaminate environmental samples from the well, resulting in nonrepresentative measurements. Both drilling fluids and preexisting fines in the formation adjacent to the well can impede the flow of water from the formation to the well, creating artifacts in hydraulic response data measured in the well.

  3. Reproducibility of Retinol Binding Protein 4 and Omentin-1 Measurements over a Four Months Period: A Reliability Study in a Cohort of 207 Apparently Healthy Participants.

    Clemens Wittenbecher

    Full Text Available The reliability of single time point measurements of the novel adipokines retinol-binding protein 4 and omentin-1 in the blood has not been evaluated in large samples yet. The present study aimed to assess the amount of biological variation of these two adipokines within individuals. The study sample comprised 207 participants (124 women and 83 men from Potsdam (Germany and surrounding areas, with an average age of 56.5 years (SD 4.2. Blood samples were collected from each participant twice, approximately four months apart. Using enzyme linked immunosorbent assays, the concentrations of retinol-binding protein 4 and omentin-1 were determined in EDTA plasma. As indicators of reliability, intraclass correlation coefficients (ICCs were calculated from the repeated biomarker measurements. The ICCs for repeated retinol-binding protein 4 and omentin-1 measurements were 0.77 (95% CI 0.71, 0.82 and 0.83 (95% CI 0.78, 0.87, respectively, indicating for both adipokines excellent reliability. ICCs were stable across strata according to sex, age, BMI, and blood pressure. Thus, for epidemiological studies it seems reasonable to rely on concentrations of retinol-binding protein 4 and omentin-1 in samples from a single time point if repeated measurements are not available.

  4. UGT2B17 genotype and the pharmacokinetic serum profile of Testosterone during substitution therapy with Testosterone Undecanoate. A retrospective experience from 207 men with hypogonadism.

    2013-07-01

    Full Text Available BackgroundTestosterone (T is mainly excreted in the urine as testosterone glucuronide (TG. This glucuronidation is partly dependent on the UGT2B17 genotype, and TG excretion is therefore lower in men having the UGT2B17 deletion. However, the possible influence of UGT2B17 genotype on serum T during androgen therapy is unknown. We retrospectively investigated the possible association between the UGT2B17 gene polymorphism and serum T levels in hypogonadal men during Testosterone undecanoate (TU substitution therapy.Subjects and methods207 patients treated with TU (Nebido® were genotyped by qPCR for the UGT2B17 deletion polymorphism. All were given 1000 mg TU per injection at 0, 6 and 18 weeks. Blood samples were taken 2 and 6 weeks after the 1st and 2nd injection, prior to the 3rd injection, and after 2-3 years of treatment. We analysed for the levels of T, luteinizing hormone, sex-hormone-binding globulin, estradiol, prostate specific antigen, haematocrit, haemoglobin and total cholesterol. ResultsThe UGT2B17 genotype frequency was: ins/ins: 42%, ins/del: 44% and del/del: 14%. During the initial 18 weeks of TU treatment, large intra- and inter-individual variations in serum T levels were observed. Large peaks in T levels, ranging from 6.7 nmol/l to 69.5 nmol/l, were noted 2 weeks after injections, regardless of the genotype. T levels did not differ between the 3 genotypes prior to the 3rd injection, but the del/del group had significantly lower levels of LH. At follow-up after 2-3 years, the injection interval or daily T dosage was not dependent on the UGT2B17 genotype. ConclusionIn conclusion, we found large intra- and inter-individual variations in serum T during standard TU treatment regimen in hypogonadal men. Only subtle differences in serum T and LH were noted according to UGT2B17 genotype, which however suggest that the UGT2B17 genotype exert modest influence on the pharmacokinetic profile of T after TU treatment.

  5. The impact of langerin (CD207)+ dendritic cells and FOXP3+ Treg cells in the small bowel mucosa of children with celiac disease and atopic dermatitis in comparison to children with functional gastrointestinal disorders.

    2016-08-01

    In the present study we aimed to evaluate the impact of langerin (CD207)+ dendritic cells (DCs) and FOXP3+ Treg cells in the intestinal mucosa of children with celiac disease (CD) and atopic dermatitis (AD) in comparison to children with functional gastrointestinal disorders (FGD). Seventy-five children (37 male, mean age 8.4 ± 4.8 years), who randomly underwent small bowel biopsy, were studied. The CD was diagnosed in 14 children, including five persons with concomitant AD (all positive for anti-tissue transglutaminase IgA antibodies and with small bowel atrophy). Normal small bowel mucosa was found in eight patients with AD and in 53 patients with FGD. The sera of all patients were tested for total and specific IgE antibodies to food allergen panels. Staining for CD11c+, langerin (CD207+) DCs, CD4+, and FOXP3+ Treg cells was performed on paraffin-embedded sections of bioptates using immunohistochemistry. The density of CD11c+ DCs, CD4+, and FOXP3+ Treg cells was higher in the CD patients compared to the AD and FGD patients (p = 0.02; p = 0.001). In AD, significantly higher density of CD11c+ DCs was detected in patients positive for specific IgE to food allergen panels (p = 0.02). The FGD patients with elevated total IgE had increased density of langerin (CD207)+ DCs compared to the patients with normal total IgE levels (p = 0.01). The increased density of FOXP3+ Treg cells, CD4+, cells and CD11c+ DCs was associated with CD but not with AD. The elevated level of total IgE or specific IgE to food allergens was associated with more pronounced expression of DCs, indicating a possible link between the presence of these cells in small bowel mucosa with elevated level of serum IgE.

  6. In vitro anticancer activity of Betulinic acid and derivatives thereof on equine melanoma cell lines from grey horses and in vivo safety assessment of the compound NVX-207 in two horses.

    Betulinic acid, a pentacyclic triterpene, and its derivatives are promising compounds for cancer treatment in humans. Melanoma is not only a problem for humans but also for grey horses as they have a high potential of developing melanoma lesions coupled to the mutation causing their phenotype. Current chemotherapeutic treatment carries the risk of adverse health effects for the horse owner or the treating veterinarian by exposure to antineoplastic compounds. Most treatments have low prospects for systemic tumor regression. Thus, a new therapy is needed. In this in vitro study, Betulinic acid and its two derivatives B10 and NVX-207, both with an improved water solubility compared to Betulinic acid, were tested on two equine melanoma cell lines (MelDuWi and MellJess/HoMelZh) and human melanoma (A375) cell line. We could demonstrate that all three compounds especially NVX-207 show high cytotoxicity on both equine melanoma cell lines. The treatment with these compounds lead to externalization of phosphatidylserines on the cell membrane (AnnexinV-staining), DNA-fragmentation (cell cycle analysis) and activation of initiator and effector caspases (Caspase assays). Our results indicate that the apoptosis is induced in the equine melanoma cells by all three compounds. Furthermore, we succeed in encapsulating the most active compound NVX-207 in 2-Hydroxyprolyl-β-cyclodextrine without a loss of its activity. This formulation can be used as a promising antitumor agent for treating grey horse melanoma. In a first tolerability evaluation in vivo the formulation was administered every one week for 19 consecutive weeks and well tolerated in two adult melanoma affected horses. PMID:26772157

  11. Reflection asymmetry in odd-A and odd-odd actinium nuclei

    Theoretical calculations and measurements indicate that octupole correlations are at a maximum in the ground states of the odd-proton nuclei Ac and Pa. It has been expected that odd-odd nuclei should have even larger amount of octupole-octupole correlations. We have recently made measurements on the structure of 224Ac. Although spin and parity assignments could not be made, two bands starting at 354.1 and 360.0 keV have properties characteristic of reflection asymmetric shape. These two bands have very similar rotational constants and also similar alpha decay rates, which suggest similarity between the wavefunctions of these bands. These signatures provide evidence for octupole correlations in these nuclides

  13. Radium-228 analysis of natural waters by Cherenkov counting of Actinium-228

    The activities of 228Ra in natural waters were determined by the Cherenkov counting of the daughter nuclide 228Ac. The radium was pre-concentrated on MnO2 and the radium purified via ion exchange and, after a 2-day period of incubation to allow for secular equilibrium between the parent-daughter 228Ra(228Ac), the daughter nuclide 228Ac was isolated by ion exchange according to the method of Nour et al. [2004. Radium-228 determination of natural waters via concentration on manganese dioxide and separation using Diphonix ion exchange resin. Appl. Radiat. Isot. 61, 1173-1178]. The Cherenkov photons produced by 228Ac were counted directly without the addition of any scintillation reagents. The optimum Cherenkov counting window, sample volume, and vial type were determined experimentally to achieve optimum Cherenkov photon detection efficiency and lowest background count rates. An optimum detection efficiency of 10.9±0.1% was measured for 228Ac by Cherenkov counting with a very low Cherenkov photon background of 0.317±0.013 cpm. The addition of sodium salicylate into the sample counting vial at a concentration of 0.1 g/mL yielded a more than 3-fold increase in the Cherenkov detection efficiency of 228Ac to 38%. Tests of the Cherenkov counting technique were conducted with several water standards of known activity and the results obtained compared closely with a conventional liquid scintillation counting technique. The advantages and disadvantages of Cherenkov counting compared to liquid scintillation counting methods are discussed. Advantages include much lower Cherenkov background count rates and consequently lower minimal detectable activities for 228Ra and no need for expensive environmentally unfriendly liquid scintillation cocktails. The disadvantages of the Cherenkov counting method include the need to measure 228Ac Cherenkov photon detection efficiency and optimum Cherenkov counting volume, which are not at all required when liquid scintillation analysis is used

  14. Linear free energy relationship applied to trivalent cations with lanthanum and actinium oxide and hydroxide structure

    Linear free energy relationships for trivalent cations with crystalline M2O3 and, M(OH)3 phases of lanthanides and actinides were developed from known thermodynamic properties of the aqueous trivalent cations, modifying the Sverjensky and Molling equation. The linear free energy relationship for trivalent cations is as ΔGf,MvX0=aMvXΔGn,M3+0+bMvX+βMvXrM3+, where the coefficients aMvX, bMvX, and βMvX characterize a particular structural family of MvX, rM3+ is the ionic radius of M3+ cation, ΔGf,MvX0 is the standard Gibbs free energy of formation of MvX and ΔGn,M3+0 is the standard non-solvation free energy of the cation. The coefficients for the oxide family are: aMvX=0.2705, bMvX=-1984.75 (kJ/mol), and βMvX=197.24 (kJ/molnm). The coefficients for the hydroxide family are: aMvX=0.1587, bMvX=-1474.09 (kJ/mol), and βMvX=791.70 (kJ/molnm).

    Kovatsch, Matthias; Lanter, Martin; Duquennoy, Simon

    2012-01-01

    Programming Internet of Things (IoT) applications is challenging because developers have to be knowledgeable in various technical domains, from low-power networking, over embedded operating systems, to distributed algorithms. Hence, it will be challenging to find enough experts to provide software for the vast number of expected devices, which must also be scalable and particularly safe due to the connection to the physical world. To remedy this situation, we propose an architecture that pr...

  16. New method for large scale production of medically applicable Actinium-225 and Radium-223

    Alpha-emitters (211At, 212Bi, 213Bi, 223Ra, 225Ac) are promising for targeted radiotherapy of cancer. Only two alpha decays near a cell membrane result in 50% death of cancer cell and only a single decay inside the cell is required for this. 225Ac may be used either directly or as a mother radionuclide in 213Bi isotope generator. Production of 225Ac is provided by three main suppliers - Institute for Transuranium Elements in Germany, Oak Ridge National Laboratory in USA and Institute of Physics and Power Engineering in Obninsk, Russia. The current worldwide production of 225Ac is approximately 1.7 Ci per year that corresponds to only 100-200 patients that could be treated annually. The common approach for 225Ac production is separation from mother 229Th or irradiation of 226Ra with protons in a cyclotron. Both the methods have some practical limitations to be applied routinely. 225Ac can be also produced by irradiation of natural thorium with medium energy protons . Cumulative cross sections of 225Ac, 227Ac, 227Th, 228Th formations have been obtained recently. Thorium targets (1-9 g) were irradiated by 114-91 MeV proton beam (1-50 μA) at INR linear accelerator. After dissolution in 8 M HNO3 + 0.004 M HF thorium was removed by double LLX by HDEHP in toluene (1:1). Ac and REE were pre-concentrated and separated from Ra and most fission products by DGA-Resin (Triskem). After washing out by 0.01 M HNO3 Ac was separated from REE by TRU Resin (Triskem) in 3 M HNO3 media. About 6 mCi 225Ac were separated in hot cell with chemical yield 85%. The method may be upscaled for production of Ci amounts of the radionuclide. The main impurity is 227Ac (0.1% at the EOB) but it does not hinder 225Ac from being used for medical 225Ac/213Bi generators. (author)

  17. Synthesis of chelating agents for actinium 225 complexation and its application in radioimmunotherapy

    Immunotherapy with radiolabeled antibodies should allow fairly specific targeting of certain cancers. However, iodine 131 may not be the best isotope for tumor therapy because of its limited specific activity, low beta-energy, relatively long half life and strong gamma emission. Another approach to improve therapeutic efficacy is the use of replacement isotopes with better physical properties. Chelator that can hold radio-metals with high stability under physiological conditions are essential to avoid excessive damage to non-target cells; Moreover, the development of new bifunctional chelating agents is essential for this purpose. Accordingly, our efforts have been directed, for several years, to the synthesis of original chelating agents likely to form stable complexes in vivo with the numerous potential candidates for such applications. Therefore, we have developed a new simple and efficient synthesis pathway of 2-(4-iso-thio-cyanate-benzyl)-1,4,7,10,13,16- hexa-aza-cyclo-hexadecane- 1,4,7,10,13,16-hexa-acetic acid, though functionalized on the cycle by a termination allowed coupling to an antibody or any other biological substance such as a hapten.

  18. Purification of selenium from thorium, uranium, radium, actinium and potassium impurities for low background measurements

    A technique of selenium purification from 232Th, 238U, 226,228Ra, 227Ac and 40K was developed. This technique is simple to perform and employs a minimum number of highly pure reagents (bidistilled water, nitric acid). Operations carried out during purification (elution, evaporation) practically exclude losses of the target product (chemical yields of Se > 99%). A test purification of 100 g of selenium was carried out using this technique. The efficiency of this technique was confirmed by low background gamma spectrometry of the purified selenium sample. Distribution coefficients of Th, U, Ra and Ac on DOWEX 50W- x 8 cation-exchange resin at different concentrations of selenium and nitric acid were experimentally determinated. Instrumental neutron activation analysis of bidistilled water, deionized water and nitric acid was performed. (orig.)

  20. Stable (206Pb, 207Pb, 208Pb) and radioactive (210Pb) lead isotopes in 1 year of growth of Sphagnum moss from four ombrotrophic bogs in southern Germany: Geochemical significance and environmental implications

    Shotyk, William; Kempter, Heike; Krachler, Michael; Zaccone, Claudio

    2015-08-01

    The surfaces of Sphagnum carpets were marked with plastic mesh and 1 year later the production of plant matter was harvested in four ombrotrophic bogs from two regions of southern Germany: Upper Bavaria (Oberbayern, OB) and the Northern Black Forest (Nordschwarzwald, NBF). Radioactive, 210Pb was determined in solid samples using ultralow background gamma spectrometry while total Pb concentrations and stable isotopes (206Pb, 207Pb, 208Pb) were determined in acid digests using ICP-SMS. Up to 12 samples (40 × 40 cm) were collected per site, and 6-10 sites investigated per bog. The greatest variations within a given sampling site were in the range 212-532 Bq kg-1 for 210Pb activity, whereas 206Pb/207Pb and 208Pb/206Pb varied less than 1%. The median values of all parameters for the sites (6-10 per bog) were not significantly different. The median activities of 210Pb (Bq kg-1) in the mosses collected from the bogs in NBF (HO = 372 ± 56, n = 55; WI = 342 ± 58, n = 93) were slightly less from those in OB (GS = 394 ± 50, n = 55; KL = 425 ± 58, n = 24). However, the mosses in the NBF bogs exhibited much greater productivity (187-202 g m-2 a-1) compared to those of OB (71-91 g m-2 a-1), and this has a profound impact on the accumulation rates of 210Pb (Bq m-2 a-1), with the bogs in the NBF yielding fluxes (HO = 73 ± 30; WI = 65 ± 20) which are twice those of OB (GS = 29 ± 11; KL = 40 ± 13). Using the air concentrations of 210Pb measured at Schauinsland (SIL) in the southern Black Forest and average annual precipitation, the atmospheric fluxes of 210Pb at SIL (340 Bq m-2 a-1) exceeds the corresponding values obtained from the mosses by a factor of five, providing the first quantitative estimate of the net retention efficiency of 210Pb by Sphagnum. When the 210Pb activities of all moss samples are combined (n = 227), a significant decrease with increasing plant production rate is observed; in contrast, total Pb concentrations show the opposite trend. The contrasting

  1. U/Pb (SHRIMP), 207Pb/206Pb, Rb/Sr, Sm/Nd e K/Ar geochronology of granite-greenstone terrains of Gaviao Block: implications for the Proterozoic and Archean evolution of Sao Francisco Craton, Brazil

    The Gaviao Block (GB) in the northern portion of the Sao Francisco Craton-Northeast of Brazil, constitutes one of the oldest Archean fragments of the South American Platform Archean crust. GB underwent several events of juvenile accretion and reworking of continental crust along its evolutionary history, notably between the Archean and the Paleoproterozoic. 207Pb/206Pb isotopic analyses were carried out in two zircons populations from strongly migmatized TTG terranes found in the proximity of Brumado: the first population (7 crystals) is taken as representative of the crystallization period of the TTG terranes at 3300 ± 45 Ma; the second (2 crystals) represents the age of the first even of metamorphism/migmatization at 2910 ± 10 Ma. 207 Pb/206 Pb analyses in zircons from an outcrop of non-migmatized TTG in the area yielded a 3202 ± 15 Ma age (4 crystals), interpreted to be the crystallization period of the gneiss protolith. Sm/Nd analyses on the TTG rocks of the Brumado region yielded TDM model ages varying between 3.26 and 3.36 Ga and εNd(t) between -3.5 and +0.7. These data suggest the occurrence of juvenile accretions to the continental crust during the Archean, with differential involvement of crustal materials. The geochemical data of rare earth elements corresponding to the TTG terranes revealed moderate LRRE contents (LaN=83,5), low HREE contents (LaN=2,5) and a fairly fractionated pattern (La/Yb)N=34, besides lack of negative Eu anomaly, showing that these rocks have similar compositions to those TTG terranes of cratonic continents, as well as some Archean rocks from CSF (e.g. Sete Voltas, Boa Vista). Finally, the youngest ages present in GB rocks (ca. 1.2-0.45 Ga) represent the role played by tectono thermal events, which produced partial or total rejuvenation of the Rb/Sr and K/Ar isotopic systems during the Espinhaco and Brasiliano cycles. In particular, K/Ar ages illustrate the effect of younger regional cooling episodes related to the Brasiliano

  3. Rb-Sr and single - zircon grain 207Pb / 206Pb chronology of the Monesterio granodiorite and related migmatites. Evidence of a Late Cambrian melting event in the Ossa-Morena Zone, Iberian Massif

    Bea, F.

    1999-04-01

    Full Text Available The Monesterio granodiorite, a small granodioritic body placed in a migmatitic complex in the SW of the Olivenza-Monesterio antiform, is a key plutonic body to understanding the relationships among the magmatism, metamorphism, and deformation in the Ossa-Morena Zone, SW Iberian Massif. We dated the granodiorite with the single zircon stepwise-evaporation 207Pb/206Pb method, and the related migmatization event with the Rb-Sr method on leucosomes. Our results indicate that the Monesterio granodiorite crystallised at 510 ± 7 Ma and its protolith had a component with Upper Proterozoic zircons with a minimum age of 1696 Ma. Leucosomes give a Rb-Sr age of 511 ± 40 Ma (MSWD =1,7 with initial 87Sr/86Sr =0.70914 ± 0.00048. The lower initial 87Sr/86Sr of the granodiorite and its calc-alkaline chemistry precludes it from having derived from the same protolith as the migmatites. The existence of different magmatic bodies in the Ossa-Morena Zone with ages clustering around 500-510 Ma reveals the existence of a significant melting event during the Late Cambrian that involved protoliths with very different geochemical and isotopic signatures.La granodiorita de Monesterio es un pequeño cuerpo emplazado en un complejo migmatítico en el SO del antiforme Olivenza-Monesterio, importante para entender las relaciones entre magmatismo, metamorfismo y deformación en la Zona de Ossa-Morena. Se ha datado la granodiorita por el método de evaporación secuencial de 207Pb/206Pb en cristal único de circón y los leucosomes de las migmatitas circundantes por el método Rb-Sr. Los datos indican una edad de cristalización de la granodiorita de 510 ± 4 Ma y un posible protolito Proterozoico Superior con una edad mínima de ∼1.700 Ma, obtenida a partir de núcleos heredados de los circones analizados. Los leucosomes dan una edad Rb-Sr de 511 ± 40 Ma, con una relación 87Sr/86Sr=0,70914 ± 0,00048. La relación inicial de 87Sr/86Sr en la granodiorita (

    Clinical therapeutic studies using {sup 225}Ac-labeled antibodies have begun. Of major concern is renal toxicity that may result from the three alpha-emitting progeny generated following the decay of {sup 225}Ac. The purpose of this study was to determine the amount of {sup 225}Ac and non-equilibrium progeny in the mouse kidney after the injection of {sup 225}Ac-huM195 antibody and examine the dosimetric consequences. Groups of mice were sacrificed at 24, 96 and 144 h after injection with {sup 225}Ac-huM195 antibody and kidneys excised. One kidney was used for gamma ray spectroscopic measurements by a high-purity germanium (HPGe) detector. The second kidney was used to generate frozen tissue sections which were examined by digital autoradiography (DAR). Two measurements were performed on each kidney specimen: (1) immediately post-resection and (2) after sufficient time for any non-equilibrium excess {sup 213}Bi to decay completely. Comparison of these measurements enabled estimation of the amount of excess {sup 213}Bi reaching the kidney ({gamma}-ray spectroscopy) and its sub-regional distribution (DAR). The average absorbed dose to whole kidney, determined by spectroscopy, was 0.77 (SD 0.21) Gy kBq{sup -1}, of which 0.46 (SD 0.16) Gy kBq{sup -1} (i.e. 60%) was due to non-equilibrium excess {sup 213}Bi. The relative contributions to renal cortex and medulla were determined by DAR. The estimated dose to the cortex from non-equilibrium excess {sup 213}Bi (0.31 (SD 0.11) Gy kBq{sup -1}) represented {approx}46% of the total. For the medulla the dose contribution from excess {sup 213}Bi (0.81 (SD 0.28) Gy kBq{sup -1}) was {approx}80% of the total. Based on these estimates, for human patients we project a kidney-absorbed dose of 0.28 Gy MBq{sup -1} following administration of {sup 225}Ac-huM195 with non-equilibrium excess {sup 213}Bi responsible for approximately 60% of the total. Methods to reduce renal accumulation of radioactive progeny appear to be necessary for the success of {sup 225}Ac radioimmunotherapy.

The geochemical data of rare earth elements corresponding to the TTG terranes revealed moderate LRRE contents (La{sub N}=83,5), low HREE contents (La{sub N}=2,5) and a fairly fractionated pattern (La/Yb){sub N}=34, besides lack of negative Eu anomaly, showing that these rocks have similar compositions to those TTG terranes of cratonic continents, as well as some Archean rocks from CSF (e.g. Sete Voltas, Boa Vista). Finally, the youngest ages present in GB rocks (ca. 1.2-0.45 Ga) represent the role played by tectono thermal events, which produced partial or total rejuvenation of the Rb/Sr and K/Ar isotopic systems during the Espinhaco and Brasiliano cycles. In particular, K/Ar ages illustrate the

    目的 了解农村留守中小学生的问题行为及家庭影响因素,为特殊群体的身心健康教育提供决策依据.方法 采用Conners儿童行为量表及白编家庭情况调查问卷,对207名小学和初中的留守学生进行调查.结果 留守中小学生的问题行为检出率为15.46%,其中品行问题检出率最高;留守中小学生的问题行为较非留守中小学生严重,其品行问题、多动、不注意-被动得分高于非留守中小学生;抚养人类别、文化程度及父母外出时间是影响留守中小学生的重要因素.结论 正常、温暖、有序的家庭环境是孩子健康成长的保证.农村留守中小学生的父母、抚养人、学校及社会应群策群力,减少中小学生行为问题的发生.%Objective To understand the problem behaviors and the influencing factors from their families of rural left-behind primary and secondary students, and to provide evidence for their mental health education. Methods Conners Child Behavior Scale, and self-compiled questionnaires to the families were used to investigate 207 elementary and junior high school students. Results The problem behavior detection rate of left-behind primary and secondary students was 15.46%, the highest detection rate were behavioral problems; the behavioral problems of home-left primary and secondary students were worse than non-left-behind students. Score of conduct problems, hyperactivity, no attention-passive were higher than score of non-left-behind students. Class and educational level of caregivers and how long their parents go out was an important affecting factor. Conclusion Normal ,warm, orderly family environment is to ensure the healthy growth of each child. Parents, caregivers, schools and society should work together to reduce home-left primary and secondary students' behavior problems.

  19. Residual nuclide formation in 206,207,208,natPb and 209Bi induced by 0.04 - 2.6 GeV protons as well as in 56Fe induced by 0.3 - 2.6 GeV protons

    This work is aimed at experimental determination of independent and cumulative yields of radioactive residual product nuclei in the intermediate energy proton-irradiated thin targets made of highly isotopic enriched and natural lead (206,207,208,natPb), bismuth (209Bi), and highly isotopic enriched iron (56Fe). 5972 independent and cumulative yields of radioactive residuals nuclei have been measured in 55 thin Pb and Bi targets irradiated by 0.04, 0.07, 0.10, 0.15, 0.25, 0.6, 0.8, 1.2, 1.4, 1.6, and 2.6 GeV protons. Besides, 219 yields have been measured in 0.3, 0.5, 0.75, 1.0, 1.5, and 2.6 GeV proton-irradiated Fe target. In both cases, the protons were extracted from the ITEP U-10 synchrotron. The measured data are compared with experimental results obtained elsewhere and with theoretical calculations by seven codes. The predictive power was found to be different for each of the codes tested, but was satisfactory on the whole in the case of spallation products. At the same time, none of the codes can describe well the product yields throughout the whole product mass range, and all codes must be further improved. (authors)

  20. A francium-223 reservoir source

    By improving and accelerating a method which had been earlier tried for caesium-rubidium separation on a cellulose column, i.e. elution with 2N HCl-equilibrated phenol, the author succeeded in obtaining consecutive and quasi-selective elutions of francium-223, starting with actinium-227 fixed at the top of a small cellulose column to which ZrO2 had been added. The francium-223, rapidly eluted under pressure, is extracted by water while the phenol is extracted by ether; it can easily be cleared of any residual traces of radioactive contaminants (thallium-207, radium-223, thorium-227) by two consecutive BaSO4 precipitations. The preparation of a Fr223 solution (HCl-H2SO4) requires approximately 20 min; the time noted for Fr223 was closer to 22 than to 21 min. (author)

  12. Translating cultural transition in Kgebetli Moele’s Room 207

    S.S. Ibinga

    2010-07-01

    Full Text Available This article deals with the issue of cultural translation in a postapartheid text through the analysis of language, setting and discourse to highlight cultural transition in a society where socio-political mutations elicit new literary codes and symbols. The discussion is developed around concepts such as gender and ethnic identity or citizenship in a geographical environment where multi- and transcultural identities are endlessly being contested. The concept of translation is explored to show how Moele’s text represents cultural transition within a postapartheid urban context by analysing the authorial transposition of everyday experience into the textual fabric. The article also examines how the narrative voice negotiates across the current multicultural divide in order to highlight cultural change both in South African literature and in society as a whole. This article addresses in the discussion the controversial debate raised by Michael Titlestad’s (2007 review of the book published in the “Sunday times” on 25 March in which the critic evinces a negative reception of the book. This is used as a point of departure in order to explore a wide range of possibilities that fiction can offer by means of textual representation of the daily experience of black people in a postapartheid urban context.

  7. Removal of actinium from europium for the determination of specific radioactivity of ultra low-level Eu-152 in a sample exposed to atomic-bomb neutrons in Nagasaki

    Measurements of specific radioactivities of residual neutron-induced radionuclides such as 152Eu and 60Co have been carried out to check the validity of a series of computer calculations employed for the atomic-bomb neutron dosimetry in Hiroshima (exposed to uranium bomb) and Nagasaki (exposed to plutonium bomb). The use of these nuclides for atomic-bomb neutron dosimetry, however, has been limited by the following difficulties: (1) today, these radionuclides are found only at extremely low concentrations in materials exposed to the atomic-bomb and (2) the neutrons that induced these radionuclides were thermal and epithermal, while the neutron dose received in Hiroshima and Nagasaki is attributable to fast neutrons. In order to overcome the first difficulty, we established a chemical procedure to extract Eu and Co from materials exposed to the atomic-bomb, and the chemical procedure has been successful for the materials exposed to atomic-bomb within 1400 m in slant distance from the explosion point. As for Nagasaki, materials exposed in the distances farther than 1200 m have never been subjected to the measurement of residual neutron-induced radionuclides. In this work, determination of specific radioactivity of 152Eu (half-life: 13.542 y) in a sample exposed to Nagasaki atomic-bomb at a distant place from the explosion point was undertaken. But, because of radioactive decay during this ∝60 years since 1945 and long distance from the explosion point, the present specific radioactivity of 152Eu in the sample is extremely low (estimated to be ∝3 x 10-4 Bq-152Eu/mg-Eu), and a serious problem is interferences from daughters of 227Ac (half-life: 21.8 y) in the measurement of ultra low-level radioactivity of 152Eu. Hence, our chemical procedure to obtain Eu-enriched counting source should be improved, and much attention is being denoted to removal of Ac from Eu. (orig.)

    Monique Togni

    2013-03-01

    Full Text Available Este estudo teve como objetivos determinar os tumores mais prevalentes em gatos e relacionar os tumores mamários a alguns de seus fatores prognósticos. Os arquivos do Laboratório de Patologia Veterinária (LPV da Universidade Federal de Santa Maria (UFSM foram revisados e um total de 1.427 protocolos de biopsias e necropsias de felinos, entre 2000 e 2011, foi encontrado. Com base nas informações dos arquivos, foi estabelecida a relação entre os tumores e alguns fatores como sexo, idade, raça, estado reprodutivo, uso de contraceptivos, número e localização das glândulas afetadas, ulcerações, tamanho do neoplasma, metástases distantes e para os linfonodos. Assim, observou-se que os tumores de mama foram o segundo diagnóstico mais prevalente, após os tumores de pele. Todos os gatos com tumores mamários eram fêmeas, sendo os sem raça definida e os idosos os mais afetados. Os neoplasmas malignos foram diagnosticados com maior frequência, seguidos pelos tumores não neoplásicos e pelos neoplasmas benignos. Os tumores menores eram, na sua maioria, carcinomas. Ulcerações estavam presentes não só em neoplasmas malignos, mas também em alterações não neoplásicas. Metástases distantes foram encontradas principalmente nos pulmões e na pele.

    Astrometric monitoring of the nearby early-L dwarf DE0823-49 has revealed a low-mass companion in a 248-day orbit that was announced in an earlier work. Here, we present new astrometric and spectroscopic observations that allow us to characterise the system in detail. The optical spectrum shows Li i-absorption indicative of a young age and/or substellar mass for the primary component. The near-infrared spectrum is best reproduced by a binary system of brown dwarfs with spectral types of L1.5 + L5.5 and effective temperatures of 2150 ± 100 K and 1670 ± 140 K. To conform with the photocentric orbit size measured with astrometry and the current understanding of substellar evolution, the system must have an age in the 80-500 Myr range. Evolutionary models predict component masses in the ranges of M1 ≃ 0.028-0.063 M⊙ and M2 ≃ 0.018-0.045 M⊙ with a mass ratio of q ≃ 0.64-0.74. Multi-epoch radial velocity measurements unambiguously establish the three-dimensional orbit of the system and allow us to investigate its kinematic properties. DE0823-49 emerges as a rare example of a nearby brown dwarf binary with orbit, component properties, and age that are characterised well. It is a juvenile resident of the solar neighbourhood, but does not appear to belong to a known young association or moving group.

    Green, Daniel W.; Arbucci, John; Silberman, Jason; Luderowski, Eva; Uppstrom, Tyler J.; Nguyen, Joseph; Tuca, Maria

    2016-01-01

    Objectives: Describe the clinical characteristics, image findings, and outcomes of patients with juvenile osteochondritis dissecans (JOCD) of the knee. To our knowledge, this is the largest single-surgeon cohort of JOCD patients. Methods: Retrospective cohort study of knee JOCD patients assessed by a single pediatric orthopaedic surgeon at a tertiary care center between 2005-2015. All diagnoses were confirmed by magnetic resonance imaging (MRI). Patients with patellar dislocations or osteochondral fractures were excluded. Demographic data, sports played, comorbidities, surgical procedures, and clinical data were extracted from charts. Images were analyzed to identify the location and size of lesions. Chi-square or Fisher’s exact tests were used to compare discrete variables, and Mann-Whitney U and Kruskal Wallis tests to compare continuous variables between groups. P-values of basketball (29.4%). JOCD was present bilaterally in 27 patients (15%), 14 knees had bifocal OCD (6.8%), and only 1 patient had bifocal lesions in both knees. Most common location was medial femoral condyle (56.3%) followed by lateral femoral condyle (23.1%), trochlea (11.4%), patella (9%), and tibia (0.5%). In the sagittal view, most common location was the middle third of the condyles (48.7%). Surgery was performed in 72 knees (34.8%), with an average age at surgery of 14.1 years (9.3-18.1). Bilateral JOCD was present in 13 surgical patients (18.8%), but only 3 patients had bilateral surgery. Two operative patients had bifocal JOCD (2.7%) and surgery on both lesions. Location distribution did not differ between surgical and non-surgical lesions. The average normalized area of non-surgical JOCD lesions was 6.8 (0.1-18), whereas surgical lesions averaged a significantly higher area of 7.7 (0.5-17) (p=0.023). Average BMI was 21.6 versus 20.2 for surgical and non-surgical patients, respectively, significantly higher for those who underwent surgery (p=0.002). Most common procedure was fixation with 1.6 mm bioabsorbable nails (54.2%), using an average of 4 nails (1-9). Only 2 cases were fixed using metallic headless screws. Other surgical treatments were drilling (13.9%), microfracture (13.9%), microfracture + fixation (6.9%), removal of loose body/chondroplasty (6.9%), and allograft transplantation (4.2%). Fixation was achieved all-arthroscopic in 43.1% of the cases, and 61.3% of the lesions that were fixed underwent curettage of the subchondral bone. Revision surgery was required in 14 knees (19.4%). The most common revision procedures were microfracture, removal of hardware, chondroplasty and allograft implantation, where some revisions had combined procedures. Most surgical patients had postoperative MRIs (55 knees), with an average radiological follow-up of 14.5 months (range 2.1-55.4). Conclusion: JOCD occurs more frequently in young adolescent athlete boys, affecting the middle third of the medial femoral condyle. In our cohort, 1/3 of the patients had surgery, where bigger lesions and higher BMI were risk factors for operative treatment. At short-term follow up, the success rate following surgery was above 80%.

  18. Generator method of 225Ac production without a carrier for nuclear medicine

    The two-steps isotope generator scheme of 225Ac production from 229Th has been developed. The first step is used for separation of thorium, actinium, radium and daughter decay products (DDP), and removals of parent radionuclide. The second step provides additional separation of actinium from traces of radium and DDP, and conversion of actinium in the nitrate form. The chosen solutions provide optimal conditions for carry out of process. The yield of the 225Ac was 99.9% at minimal losses of parent 229Th (less than 0.1%)

  20. Feather lead concentrations and207Pb/206Pb ratios reveal lead exposure history of California condors (Gymnogyps californianus)

    2010-01-01

    Lead poisoning is a primary factor impeding the survival and recovery of the critically endangered California Condor (Gymnogyps californianus). However, the frequency and magnitude of lead exposure in condors is not well-known in part because most blood lead monitoring occurs biannually, and biannual blood samples capture only ???10% of a bird's annual exposure history. We investigated the use of growing feathers from free-flying condors in California to establish a bird's lead exposure history. We show that lead concentration and stable lead isotopic composition analyses of sequential feather sections and concurrently collected blood samples provided a comprehensive history of lead exposure over the 2-4 month period of feather growth. Feather analyses identified exposure events not evident from blood monitoring efforts, and by fitting an empirically derived timeline to actively growing feathers, we were able to estimate the time frame for specific lead exposure events. Our results demonstrate the utility of using sequentially sampled feathers to reconstruct lead exposure history. Since exposure risk in individuals is one determinant ?? 2010 American Chemical Society.

  4. SU-C-207-01: Four-Dimensional Inverse Geometry Computed Tomography: Concept and Its Validation

    Purpose: In past few years, the inverse geometry computed tomography (IGCT) system has been developed to overcome shortcomings of a conventional computed tomography (CT) system such as scatter problem induced from large detector size and cone-beam artifact. In this study, we intend to present a concept of a four-dimensional (4D) IGCT system that has positive aspects above all with temporal resolution for dynamic studies and reduction of motion artifact. Methods: Contrary to conventional CT system, projection data at a certain angle in IGCT was a group of fractionated narrow cone-beam projection data, projection group (PG), acquired from multi-source array which have extremely short time gap of sequential operation between each of sources. At this, for 4D IGCT imaging, time-related data acquisition parameters were determined by combining multi-source scanning time for collecting one PG with conventional 4D CBCT data acquisition sequence. Over a gantry rotation, acquired PGs from multi-source array were tagged time and angle for 4D image reconstruction. Acquired PGs were sorted into 10 phase and image reconstructions were independently performed at each phase. Image reconstruction algorithm based upon filtered-backprojection was used in this study. Results: The 4D IGCT had uniform image without cone-beam artifact on the contrary to 4D CBCT image. In addition, the 4D IGCT images of each phase had no significant artifact induced from motion compared with 3D CT. Conclusion: The 4D IGCT image seems to give relatively accurate dynamic information of patient anatomy based on the results were more endurable than 3D CT about motion artifact. From this, it will be useful for dynamic study and respiratory-correlated radiation therapy.

  6. SU-D-207-01: Markerless Respiratory Motion Tracking with Contrast Enhanced Thoracic Cone Beam CT Projections

    Purpose: To develop a novel technique to enhance the image contrast of clinical cone beam CT projections and extract respiratory signals based on anatomical motion using the modified Amsterdam Shroud (AS) method to benefit image guided radiation therapy. Methods: Thoracic cone beam CT projections acquired prior to treatment were preprocessed to increase their contrast for better respiratory signal extraction. Air intensity on raw images was firstly estimated and then applied to correct the projections to generate new attenuation images that were subsequently improved with deeper anatomy feature enhancement through taking logarithm operation, derivative along superior-inferior direction, respectively. All pixels on individual post-processed two dimensional images were horizontally summed to one column and all projections were combined side by side to create an AS image from which patient’s respiratory signal was extracted. The impact of gantry rotation on the breathing signal rendering was also investigated. Ten projection image sets from five lung cancer patients acquired with the Varian Onboard Imager on 21iX Clinac (Varian Medical Systems, Palo Alto, CA) were employed to assess the proposed technique. Results: Application of the air correction on raw projections showed that more than an order of magnitude of contrast enhancement was achievable. The typical contrast on the raw projections is around 0.02 while that on attenuation images could greater than 0.5. Clear and stable breathing signal can be reliably extracted from the new images while the uncorrected projection sets failed to yield clear signals most of the time. Conclusion: Anatomy feature plays a key role in yielding breathing signal from the projection images using the AS technique. The air correction process facilitated the contrast enhancement significantly and attenuation images thus obtained provides a practical solution to obtaining markerless breathing motion tracking

  14. SU-E-J-207: Effect of Pulse Sequence Parameters On Geometric Distortions Induced by a Titanium Brachytherapy Applicator

    2015-06-15

    Purpose: To investigate the effect of readout bandwidth and voxel size on the appearance of distortion artifacts caused by a titanium brachytherapy applicator. Methods: An acrylic phantom was constructed to rigidly hold a MR conditional, titanium Fletcher-Suit-Delclos-style applicator set (Varian Medical Systems) for imaging on CT (Philips Brilliance) and 1.5T MRI (Siemens Magnetom Aera). Several variants of MRI parameters were tried for 2D T2-weighted turbo spin echo imaging in comparison against the standard clinical protocol with the criteria to keep relative SNR loss less than 20% and imaging time as short as possible. Two 3D sequences were also used for comparison with similar parameters. The applicator tandem was segmented on axial CT images (0.4×0.4×1.5mm {sup 3} resolution) and the CT images were registered to the 3D MR images in Eclipse (Varian). The applicator volume was then overlaid on all MRI sets in 3D-Slicer and distances were measured from the tandem tip to the MRI artifact edge in right/left/superior and anterior/posterior/superior directions from coronal and sagittal 2D acquisitions, respectively, or 3D data reformats. Artifact regions were also manually contoured in coronal/sagittal orientations for area measurements. Results: As would be expected, reductions in voxel size and increases in readout bandwidth reduced artifact size (average max artifact length decreased by 0.95 mm and average max area decrease by 0.27 cm{sup 2}). Interestingly, bandwidth increases yielded reductions in area (0.19 cm{sup 2}) and in distance measurements (1 mm) even with voxel increases, as compared to a standard protocol. This could be useful when high performance protocols are not feasible due to long imaging times. Conclusion: We have characterized artifacts caused by cervical brachytherapy applicator across multiple sequence parameters at 1.5T. Future work will focus on finalizing an optimal protocol that balances artifact reduction with imaging time and then testing this new protocol in patients.

  19. SU-E-J-207: Effect of Pulse Sequence Parameters On Geometric Distortions Induced by a Titanium Brachytherapy Applicator

    Purpose: To investigate the effect of readout bandwidth and voxel size on the appearance of distortion artifacts caused by a titanium brachytherapy applicator. Methods: An acrylic phantom was constructed to rigidly hold a MR conditional, titanium Fletcher-Suit-Delclos-style applicator set (Varian Medical Systems) for imaging on CT (Philips Brilliance) and 1.5T MRI (Siemens Magnetom Aera). Several variants of MRI parameters were tried for 2D T2-weighted turbo spin echo imaging in comparison against the standard clinical protocol with the criteria to keep relative SNR loss less than 20% and imaging time as short as possible. Two 3D sequences were also used for comparison with similar parameters. The applicator tandem was segmented on axial CT images (0.4×0.4×1.5mm 3 resolution) and the CT images were registered to the 3D MR images in Eclipse (Varian). The applicator volume was then overlaid on all MRI sets in 3D-Slicer and distances were measured from the tandem tip to the MRI artifact edge in right/left/superior and anterior/posterior/superior directions from coronal and sagittal 2D acquisitions, respectively, or 3D data reformats. Artifact regions were also manually contoured in coronal/sagittal orientations for area measurements. Results: As would be expected, reductions in voxel size and increases in readout bandwidth reduced artifact size (average max artifact length decreased by 0.95 mm and average max area decrease by 0.27 cm2). Interestingly, bandwidth increases yielded reductions in area (0.19 cm2) and in distance measurements (1 mm) even with voxel increases, as compared to a standard protocol. This could be useful when high performance protocols are not feasible due to long imaging times. Conclusion: We have characterized artifacts caused by cervical brachytherapy applicator across multiple sequence parameters at 1.5T. Future work will focus on finalizing an optimal protocol that balances artifact reduction with imaging time and then testing this new protocol in patients

  2. Application of AMI 207A automatic welding to the erection engineering of electric instrument tube of nuclear powre plant

    The industrial application of automatic, intelligent and high-precision parameter-controlled welding equipment has become true long age in the western developed countries. However, this kind of equipment has been seldom used in China, especially on the erection site of nuclear power construction. In the Phase III of Qinshan Nuclear Power Project, we used the American AMI (Arc Machines, Inc.) 208A automatic welding equipment and technology to have all grooves of the electric instrument tubes automatically welded. The practice has proved that the automatic welding is more advanced, highly effective and more economic compared with other welding processes. (authors)

This trial would randomize subjects who had substantial risk of lung cancer (due to age and smoking h...

  12. SU-D-207-05: Real-Time Intrafractional Motion Tracking During VMAT Delivery Using a Conventional Elekta CBCT System

    Purpose: Real-time kV projection streaming capability has become recently available for Elekta XVI version 5.0. This study aims to investigate the feasibility and accuracy of real-time fiducial marker tracking during CBCT acquisition with or without simultaneous VMAT delivery using a conventional Elekta linear accelerator. Methods: A client computer was connected to an on-board kV imaging system computer, and receives and processes projection images immediately after image acquisition. In-house marker tracking software based on FFT normalized cross-correlation was developed and installed in the client computer. Three gold fiducial markers with 3 mm length were implanted in a pelvis-shaped phantom with 36 cm width. The phantom was placed on a programmable motion platform oscillating in anterior-posterior and superior-inferior directions simultaneously. The marker motion was tracked in real-time for (1) a kV-only CBCT scan with treatment beam off and (2) a kV CBCT scan during a 6-MV VMAT delivery. The exposure parameters per projection were 120 kVp and 1.6 mAs. Tracking accuracy was assessed by comparing superior-inferior positions between the programmed and tracked trajectories. Results: The projection images were successfully transferred to the client computer at a frequency of about 5 Hz. In the kV-only scan, highly accurate marker tracking was achieved over the entire range of cone-beam projection angles (detection rate / tracking error were 100.0% / 0.6±0.5 mm). In the kV-VMAT scan, MV-scatter degraded image quality, particularly for lateral projections passing through the thickest part of the phantom (kV source angle ranging 70°-110° and 250°-290°), resulting in a reduced detection rate (90.5%). If the lateral projections are excluded, tracking performance was comparable to the kV-only case (detection rate / tracking error were 100.0% / 0.8±0.5 mm). Conclusion: Our phantom study demonstrated a promising Result for real-time motion tracking using a conventional Elekta linear accelerator. MV-scatter suppression is needed to improve tracking accuracy during MV delivery. This research is funded by Motion Management Research Grant from Elekta

  14. SU-D-207-03: Development of 4D-CBCT Imaging System with Dual Source KV X-Ray Tubes

    Purpose: The purposes of this work are to develop 4D-CBCT imaging system with orthogonal dual source kV X-ray tubes, and to determine the imaging doses from 4D-CBCT scans. Methods: Dual source kV X-ray tubes were used for the 4D-CBCT imaging. The maximum CBCT field of view was 200 mm in diameter and 150 mm in length, and the imaging parameters were 110 kV, 160 mA and 5 ms. The rotational angle was 105°, the rotational speed of the gantry was 1.5°/s, the gantry rotation time was 70 s, and the image acquisition interval was 0.3°. The observed amplitude of infrared marker motion during respiration was used to sort each image into eight respiratory phase bins. The EGSnrc/BEAMnrc and EGSnrc/DOSXYZnrc packages were used to simulate kV X-ray dose distributions of 4D-CBCT imaging. The kV X-ray dose distributions were calculated for 9 lung cancer patients based on the planning CT images with dose calculation grid size of 2.5 x 2.5 x 2.5 mm. The dose covering a 2-cc volume of skin (D2cc), defined as the inner 5 mm of the skin surface with the exception of bone structure, was assessed. Results: A moving object was well identified on 4D-CBCT images in a phantom study. Given a gantry rotational angle of 105° and the configuration of kV X-ray imaging subsystems, both kV X-ray fields overlapped at a part of skin surface. The D2cc for the 4D-CBCT scans was in the range 73.8–105.4 mGy. Linear correlation coefficient between the 1000 minus averaged SSD during CBCT scanning and D2cc was −0.65 (with a slope of −0.17) for the 4D-CBCT scans. Conclusion: We have developed 4D-CBCT imaging system with dual source kV X-ray tubes. The total imaging dose with 4D-CBCT scans was up to 105.4 mGy

  15. SU-D-207-07: Implementation of Full/half Bowtie Filter Model in a Commercial Treatment Planning System for Kilovoltage X-Ray Imaging Dose Estimation

    Kim, S [Advocate Lutheran General Hospital, Park Ridge, IL (United States); Alaei, P [Univ Minnesota, Minneapolis, MN (United States)

    2015-06-15

    Purpose: To implement full/half bowtie filter models in a commercial treatment planning system (TPS) to calculate kilovoltage (kV) x-ray imaging dose of Varian On-Board Imager (OBI) cone beam CT (CBCT) system. Methods: Full/half bowtie filters of Varian OBI were created as compensator models in Pinnacle TPS (version 9.6) using Matlab software (version 2011a). The profiles of both bowtie filters were acquired from the manufacturer, imported into the Matlab system and hard coded in binary file format. A Pinnacle script was written to import each bowtie filter data into a Pinnacle treatment plan as a compensator. A kV x-ray beam model without including the compensator model was commissioned per each bowtie filter setting based on percent depth dose and lateral profile data acquired from Monte Carlo simulations. To validate the bowtie filter models, a rectangular water phantom was generated in the planning system and an anterior/posterior beam with each bowtie filter was created. Using the Pinnacle script, each bowtie filter compensator was added to the treatment plan. Lateral profile at the depth of 3cm and percent depth dose were measured using an ion chamber and compared with the data extracted from the treatment plans. Results: The kV x-ray beams for both full and half bowtie filter have been modeled in a commercial TPS. The difference of lateral and depth dose profiles between dose calculations and ion chamber measurements were within 6%. Conclusion: Both full/half bowtie filter models provide reasonable results in kV x-ray dose calculations in the water phantom. This study demonstrates the possibility of using a model-based treatment planning system to calculate the kV imaging dose for both full and half bowtie filter modes. Further study is to be performed to evaluate the models in clinical situations.

  16. SU-C-207-05: A Comparative Study of Noise-Reduction Algorithms for Low-Dose Cone-Beam Computed Tomography

    Purpose: To study different noise-reduction algorithms and to improve the image quality of low dose cone beam CT for patient positioning in radiation therapy. Methods: In low-dose cone-beam CT, the reconstructed image is contaminated with excessive quantum noise. In this study, three well-developed noise reduction algorithms namely, a) penalized weighted least square (PWLS) method, b) split-Bregman total variation (TV) method, and c) compressed sensing (CS) method were studied and applied to the images of a computer–simulated “Shepp-Logan” phantom and a physical CATPHAN phantom. Up to 20% additive Gaussian noise was added to the Shepp-Logan phantom. The CATPHAN phantom was scanned by a Varian OBI system with 100 kVp, 4 ms and 20 mA. For comparing the performance of these algorithms, peak signal-to-noise ratio (PSNR) of the denoised images was computed. Results: The algorithms were shown to have the potential in reducing the noise level for low-dose CBCT images. For Shepp-Logan phantom, an improvement of PSNR of 2 dB, 3.1 dB and 4 dB was observed using PWLS, TV and CS respectively, while for CATPHAN, the improvement was 1.2 dB, 1.8 dB and 2.1 dB, respectively. Conclusion: Penalized weighted least square, total variation and compressed sensing methods were studied and compared for reducing the noise on a simulated phantom and a physical phantom scanned by low-dose CBCT. The techniques have shown promising results for noise reduction in terms of PSNR improvement. However, reducing the noise without compromising the smoothness and resolution of the image needs more extensive research

  20. SU-D-207-06: Clinical Validations of Shading Correction for Cone-Beam CT Using Planning CT as a Prior

    Purpose: Current cone-beam CT (CBCT) images contain severe shading artifacts mainly due to scatter, hindering their quantitative use in current radiation therapy. We have previously proposed an effective shading correction method for CBCT using planning CT (pCT) as prior knowledge. In this work, we investigate the method robustness via statistical analyses on studies of a large patient group and compare the performance with that of a state-of-the-art method implemented on the current commercial radiation therapy machine -- the Varian Truebeam system. Methods: Since radiotherapy patients routinely undergo multiple-detector CT (MDCT) scans in the planning procedure, we use the high-quality pCT as “free” prior knowledge for CBCT image improvement. The CBCT image with no correction is first spatially registered with the pCT. Primary CBCT projections are estimated via forward projections of the registered image. The low frequency errors in the projections, which stem from mainly scatter, are estimated by filtering the difference between original line integral and the estimated scatter projections. The corrected CBCT image is then reconstructed from the scatter corrected projections. The proposed method is evaluated on 40 cancer patients. Results: On all patient images, we compare errors on CT number, spatial non-uniformity (SNU) and image contrast, using pCT as the ground truth. T-tests show that our algorithm improves over the Varian method on CBCT accuracies of CT number and SNU with 90% confident. The average CT number error is reduced from 54.8 HU on the Varian method to 40.9 HU, and the SNU error is reduced from 7.7% to 3.8%. There is no obvious improvement on image contrast. Conclusion: Large-group patient studies show that the proposed pCT-based algorithm outperforms the Varian method of the Truebeam system on CBCT shading correction, by providing CBCT images with higher CT number accuracy and greater image uniformity

  1. SU-C-207-04: Reconstruction Artifact Reduction in X-Ray Cone Beam CT Using a Treatment Couch Model

    Lasio, G; Hu, E; Zhou, J; Lee, M; Yi, B [University of Maryland School of Medicine, Baltimore, MD (United States)

    2015-06-15

    Purpose: to mitigate artifacts induced by the presence of the RT treatment couch in on-board CBCT and improve image quality Methods: a model of a Varian IGRT couch is constructed using a CBCT scan of the couch in air. The model is used to generate a set of forward projections (FP) of the treatment couch at specified gantry angles. The model couch forward projections are then used to process CBCT scan projections which contain the couch in addition to the scan object (Catphan phantom), in order to remove the attenuation component of the couch at any given gantry angle. Prior to pre-processing with the model FP, the Catphan projection data is normalized to an air scan with bowtie filter. The filtered Catphan projections are used to reconstruct the CBCT with an in-house FDK algorithm. The artifact reduction in the processed CBCT scan is assessed visually, and the image quality improvement is measured with the CNR over a few selected ROIs of the Catphan modules. Results: Sufficient match between the forward projected data and the x-ray projections is achieved to allow filtering in attenuation space. Visual improvement of the couch induced artifacts is achieved, with a moderate expense of CNR. Conclusion: Couch model-based correction of CBCT projection data has a potential for qualitative improvement of clinical CBCT scans, without requiring position specific correction data. The technique could be used to produce models of other artifact inducing devices, such as immobilization boards, and reduce their impact on patient CBCT images.

  4. SU-C-207-02: A Method to Estimate the Average Planar Dose From a C-Arm CBCT Acquisition

    Supanich, MP [Rush University Medical Center, Chicago, IL (United States)

    2015-06-15

    Purpose: The planar average dose in a C-arm Cone Beam CT (CBCT) acquisition had been estimated in the past by averaging the four peripheral dose measurements in a CTDI phantom and then using the standard 2/3rds peripheral and 1/3 central CTDIw method (hereafter referred to as Dw). The accuracy of this assumption has not been investigated and the purpose of this work is to test the presumed relationship. Methods: Dose measurements were made in the central plane of two consecutively placed 16cm CTDI phantoms using a 0.6cc ionization chamber at each of the 4 peripheral dose bores and in the central dose bore for a C-arm CBCT protocol. The same setup was scanned with a circular cut-out of radiosensitive gafchromic film positioned between the two phantoms to capture the planar dose distribution. Calibration curves for color pixel value after scanning were generated from film strips irradiated at different known dose levels. The planar average dose for red and green pixel values was calculated by summing the dose values in the irradiated circular film cut out. Dw was calculated using the ionization chamber measurements and film dose values at the location of each of the dose bores. Results: The planar average dose using both the red and green pixel color calibration curves were within 10% agreement of the planar average dose estimated using the Dw method of film dose values at the bore locations. Additionally, an average of the planar average doses calculated using the red and green calibration curves differed from the ionization chamber Dw estimate by only 5%. Conclusion: The method of calculating the planar average dose at the central plane of a C-arm CBCT non-360 rotation by calculating Dw from peripheral and central dose bore measurements is a reasonable approach to estimating the planar average dose.

  6. 206/207Pb and Radiocarbon: An Unlikely Pair for Identifying the Source and Delivery Time of Ocean Advection in the South China Sea

    Switzer, A.; Goodkin, N.; Bolton, A.; Chen, M.; Druffel, E. R. M.; Boyle, E. A.

    2015-12-01

    Two independent studies were undertaken to use anthropogenic emissions to investigate natural systems using a massive Porites coral taken from off the coast of Vietnam (12ο12'49.90"N, 109 ο18'17.51"E). Annual uptake of bomb radiocarbon (14CO2) was measured to investigate the impact of coastal upwelling; while Pb/Ca levels and Pb isotopes were measured to investigate oceanic infiltration of anthropogenic Pb. Both records reveal a signal of sub-surface seawater advection from the tropical North Pacific to the South China Sea (SCS) providing independent evidence for the source and delivery time of the upwelled water off the coast of Vietnam. The radiocarbon record, extending from 1900-1986 at ~annual resolution, shows a post-bomb peak lower and broader than those found from other corals in the SCS and Japan, but higher than those found in the Makassar Strait in Indonesia. The Makassar coral experiences three water masses: the South Equatorial Current (SEC), upwelled and SCS water. The SEC has a relatively low radiocarbon content. However, water in the SCS does not mix with SEC water that enters the Indonesia Seas via the Halmahera as the main throughflow is from north to south. Hence, the upwelling signature must be from the North Equatorial Current that enters from the Luzon strait at depth. Leaded gasoline was phased-out between 1997 and 2000 in most Asian countries, however unlike other regional records, the Pb/Ca of the coral continued to increase until 2004 indicating a non-atmospheric source of Pb to the region. Both records indicate the source of upwelled water from the tropical North Pacific at roughly ~100-200 meters with a transport time of >2-5 years. This water is carried westward, via the Luzon Strait and into the South China Sea, where is it upwelled during the summer months. A higher resolution study of this coral combined with other coral records from the region could further narrow the location and timing of the advection and upwelling.

  7. SU-C-207-02: A Method to Estimate the Average Planar Dose From a C-Arm CBCT Acquisition

    Purpose: The planar average dose in a C-arm Cone Beam CT (CBCT) acquisition had been estimated in the past by averaging the four peripheral dose measurements in a CTDI phantom and then using the standard 2/3rds peripheral and 1/3 central CTDIw method (hereafter referred to as Dw). The accuracy of this assumption has not been investigated and the purpose of this work is to test the presumed relationship. Methods: Dose measurements were made in the central plane of two consecutively placed 16cm CTDI phantoms using a 0.6cc ionization chamber at each of the 4 peripheral dose bores and in the central dose bore for a C-arm CBCT protocol. The same setup was scanned with a circular cut-out of radiosensitive gafchromic film positioned between the two phantoms to capture the planar dose distribution. Calibration curves for color pixel value after scanning were generated from film strips irradiated at different known dose levels. The planar average dose for red and green pixel values was calculated by summing the dose values in the irradiated circular film cut out. Dw was calculated using the ionization chamber measurements and film dose values at the location of each of the dose bores. Results: The planar average dose using both the red and green pixel color calibration curves were within 10% agreement of the planar average dose estimated using the Dw method of film dose values at the bore locations. Additionally, an average of the planar average doses calculated using the red and green calibration curves differed from the ionization chamber Dw estimate by only 5%. Conclusion: The method of calculating the planar average dose at the central plane of a C-arm CBCT non-360 rotation by calculating Dw from peripheral and central dose bore measurements is a reasonable approach to estimating the planar average dose.

    2015-06-15

    Purpose: The purposes of this work are to develop 4D-CBCT imaging system with orthogonal dual source kV X-ray tubes, and to determine the imaging doses from 4D-CBCT scans. Methods: Dual source kV X-ray tubes were used for the 4D-CBCT imaging. The maximum CBCT field of view was 200 mm in diameter and 150 mm in length, and the imaging parameters were 110 kV, 160 mA and 5 ms. The rotational angle was 105°, the rotational speed of the gantry was 1.5°/s, the gantry rotation time was 70 s, and the image acquisition interval was 0.3°. The observed amplitude of infrared marker motion during respiration was used to sort each image into eight respiratory phase bins. The EGSnrc/BEAMnrc and EGSnrc/DOSXYZnrc packages were used to simulate kV X-ray dose distributions of 4D-CBCT imaging. The kV X-ray dose distributions were calculated for 9 lung cancer patients based on the planning CT images with dose calculation grid size of 2.5 x 2.5 x 2.5 mm. The dose covering a 2-cc volume of skin (D2cc), defined as the inner 5 mm of the skin surface with the exception of bone structure, was assessed. Results: A moving object was well identified on 4D-CBCT images in a phantom study. Given a gantry rotational angle of 105° and the configuration of kV X-ray imaging subsystems, both kV X-ray fields overlapped at a part of skin surface. The D2cc for the 4D-CBCT scans was in the range 73.8–105.4 mGy. Linear correlation coefficient between the 1000 minus averaged SSD during CBCT scanning and D2cc was −0.65 (with a slope of −0.17) for the 4D-CBCT scans. Conclusion: We have developed 4D-CBCT imaging system with dual source kV X-ray tubes. The total imaging dose with 4D-CBCT scans was up to 105.4 mGy.

  10. SU-C-207-07: Quantification of Coronary Artery Cross-Sectional Area in CT Angiography Using Integrated Density: A Phantom Study

    Purpose: To investigate the feasibility of quantifying the cross-sectional area (CSA) of coronary arteries using integrated density in a physics-based model with a phantom study. Methods: In this technique the total integrated density of the object as compared with its local background is measured so it is possible to account for the partial volume effect. The proposed method was compared to manual segmentation using CT scans of a 10 cm diameter Lucite cylinder placed inside a chest phantom. Holes with cross-sectional areas from 1.4 to 12.3 mm2 were drilled into the Lucite and filled with iodine solution, producing a contrast-to-noise ratio of approximately 26. Lucite rods 1.6 mm in diameter were used to simulate plaques. The phantom was imaged with and without the Lucite rods placed in the holes to simulate diseased and normal arteries, respectively. Linear regression analysis was used, and the root-mean-square deviations (RMSD) and errors (RMSE) were computed to assess the precision and accuracy of the measurements. In the case of manual segmentation, two readers independently delineated the lumen in order to quantify the inter-reader variability. Results: The precision and accuracy for the normal vessels using the integrated density technique were 0.32 mm2 and 0.32 mm2, respectively. The corresponding results for the manual segmentation were 0.51 mm2 and 0.56 mm2. In the case of diseased vessels, the precision and accuracy of the integrated density technique were 0.46 mm2 and 0.55 mm2, respectively. The corresponding results for the manual segmentation were 0.75 mm2 and 0.98 mm2. The mean percent difference for the two readers was found to be 8.4%. Conclusion: The CSA based on integrated density had improved precision and accuracy as compared with manual segmentation in a Lucite phantom. The results indicate the potential for using integrated density to improve CSA measurements in CT angiography

We sense, experience, and act on the basis of internal processes, but which criteria constitute the basis of these processes and how does the internal “control system”, which we all have, function? Moreover, we need to take a closer look at the ways in which the organic and sustainable mechanisms of our living organisms are opt...

  12. SU-C-207-06: In Vivo Quantification of Gold Nanoparticles Using K-Edge Imaging Via Spectrum Shaping by Gold Filter

    Purpose: Gold nanoparticles (AuNP) are multifunctional platforms ideal for drug delivery, targeted imaging and radiosensitization. We have investigated quantitative imaging of AuNPs using on board imager (OBI) cone beam computed tomography (CBCT). To this end, we also present, for the first time, a novel method for k-edge imaging of AuNP by filter-based spectral shaping. Methods: We used a digital 25 cm diameter water phantom, embedded with 3 cm spheres filled with AuNPs of different concentrations (0 mg/ml – 16 mg/ml). A poly-energetic X-ray spectrum of 140 kVp from a conventional X-ray tube is shaped by balanced K-edge filters to create an excess of photons right above the K-edge of gold at 80.7 keV. The filters consist of gold, tin, copper and aluminum foils. The phantom with appropriately assigned attenuation coefficients is forward projected onto a detector for each energy bin and then integrated. FKD reconstruction is performed on the integrated projections. Scatter, detector efficiency and noise are included. Results: We found that subtracting the results of two filter sets (Filter A:127 µm gold foil with 254 µm tin, 330 µm copper and 1 mm aluminum, and Filter B: 635 µm tin with 264 µm copper and 1 mm aluminum), provides substantial image contrast. The resulting filtered spectra match well below 80.7 keV, while maintaining sufficient X-ray quanta just above that. Voxel intensities of AuNP containing spheres increase linearly with AuNP concentration. K-edge imaging provides 18% more sensitivity than the tin filter alone, and 38% more sensitivity than the gold filter alone. Conclusion: We have shown that it is feasible to quantitatively detect AuNP distributions in a patient-sized phantom using clinical CBCT and K-edge spectral shaping

    2015-06-15

    Purpose: To study different noise-reduction algorithms and to improve the image quality of low dose cone beam CT for patient positioning in radiation therapy. Methods: In low-dose cone-beam CT, the reconstructed image is contaminated with excessive quantum noise. In this study, three well-developed noise reduction algorithms namely, a) penalized weighted least square (PWLS) method, b) split-Bregman total variation (TV) method, and c) compressed sensing (CS) method were studied and applied to the images of a computer–simulated “Shepp-Logan” phantom and a physical CATPHAN phantom. Up to 20% additive Gaussian noise was added to the Shepp-Logan phantom. The CATPHAN phantom was scanned by a Varian OBI system with 100 kVp, 4 ms and 20 mA. For comparing the performance of these algorithms, peak signal-to-noise ratio (PSNR) of the denoised images was computed. Results: The algorithms were shown to have the potential in reducing the noise level for low-dose CBCT images. For Shepp-Logan phantom, an improvement of PSNR of 2 dB, 3.1 dB and 4 dB was observed using PWLS, TV and CS respectively, while for CATPHAN, the improvement was 1.2 dB, 1.8 dB and 2.1 dB, respectively. Conclusion: Penalized weighted least square, total variation and compressed sensing methods were studied and compared for reducing the noise on a simulated phantom and a physical phantom scanned by low-dose CBCT. The techniques have shown promising results for noise reduction in terms of PSNR improvement. However, reducing the noise without compromising the smoothness and resolution of the image needs more extensive research.

  15. SU-D-207-07: Implementation of Full/half Bowtie Filter Model in a Commercial Treatment Planning System for Kilovoltage X-Ray Imaging Dose Estimation

    Purpose: To implement full/half bowtie filter models in a commercial treatment planning system (TPS) to calculate kilovoltage (kV) x-ray imaging dose of Varian On-Board Imager (OBI) cone beam CT (CBCT) system. Methods: Full/half bowtie filters of Varian OBI were created as compensator models in Pinnacle TPS (version 9.6) using Matlab software (version 2011a). The profiles of both bowtie filters were acquired from the manufacturer, imported into the Matlab system and hard coded in binary file format. A Pinnacle script was written to import each bowtie filter data into a Pinnacle treatment plan as a compensator. A kV x-ray beam model without including the compensator model was commissioned per each bowtie filter setting based on percent depth dose and lateral profile data acquired from Monte Carlo simulations. To validate the bowtie filter models, a rectangular water phantom was generated in the planning system and an anterior/posterior beam with each bowtie filter was created. Using the Pinnacle script, each bowtie filter compensator was added to the treatment plan. Lateral profile at the depth of 3cm and percent depth dose were measured using an ion chamber and compared with the data extracted from the treatment plans. Results: The kV x-ray beams for both full and half bowtie filter have been modeled in a commercial TPS. The difference of lateral and depth dose profiles between dose calculations and ion chamber measurements were within 6%. Conclusion: Both full/half bowtie filter models provide reasonable results in kV x-ray dose calculations in the water phantom. This study demonstrates the possibility of using a model-based treatment planning system to calculate the kV imaging dose for both full and half bowtie filter modes. Further study is to be performed to evaluate the models in clinical situations

    Full Text Available O experimento foi conduzido para avaliar o efeito da inclusão da semente residual de urucum (SRU sobre o desempenho e qualidade dos ovos de poedeiras comerciais alimentadas com rações contendo sorgo. Cento e quarenta e quatro poedeiras comerciais foram distribuídas em um delineamento inteiramente ao acaso com seis tratamentos e seis repetições de quatro aves. Os tratamentos consistiram em uma ração � base de milho e, as demais, � base de sorgo com a inclusão de 0,0; 0,5; 1,0;1,5 e 2,0% de SRU. As variáveis: consumo de ração, percentagem de postura, peso e massa de ovo, conversão alimentar, percentagem de gema, albúmem e casca e unidades Haugh não foram afetadas significativamente pelos níveis de inclusão de SRU. Entretanto, a pigmentação da gema aumentou linearmente com o aumento de SRU na ração. A inclusão de 2% de SRU em rações contendo sorgo foi capaz de pigmentar as gemas em, aproximadamente, 61,4% da pigmentação obtida em rações compostas por milho.This experiment was conducted to evaluate the effect of inclusion of annatto (Bixa orellana L. seed byproduct (ASB in diets with sorghum on laying hens performance and eggs characteristics.

Treatments consisted of one diet based on corn and the five others based on sorghum with the inclusion of 0.0; 0.5; 1.0; 1.5 and 2.0% of ASB. Feed intake, egg production, egg weight, egg mass, feed conversion, yolk, albumen and shell percentages and Haugh units were not affected by the inclusion levels of ASB. However, yolk colour increased linearly as ASB increased in diet. The inclusion of 2% of annatto seed byproduct on laying hens diets based on sorghum improves egg yolk colour nearly 61.4% of that obtained with birds fed diet based on yellow corn.

  18. Sorption studies of radioelements on geological materials

    Batch sorption experiments have been carried out to study the sorption of uranium, technetium, curium, neptunium, actinium, protactinium, polonium, americium and plutonium onto bentonite, granodiorite and tuff. Mathematical modelling using the HARPHRQ program and the HATCHES database was carried out to predict the speciation of uranium and technetium in the equilibrated seawater, and neptunium, americium and plutonium in the rock equilibrated water. Review of the literature for thermodynamic data for curium, actinium, protactinium and polonium was carried out. Where sufficient data were available, predictions of the speciation and solubility were made. This report is a summary report of the experimental work conducted by AEA Technology during April 1991-March 1998, and the main results have been presented at Material Research Society Symposium Proceedings and published as proceedings of them.

  19. Investigation for determining the retention properties of rock over the ASSE II mine for dissolved radionuclides

    For a model consideration of groundwater movement and the associated transport of dissolved substance in deep groundwater, the retention properties of the ASSE II mine for radionuclides dissolved in water were determined. A series of properties of rocks were examined and described for this purpose. Apart from the chemical, mineralogical and petrophysical characteristics of the rocks, the retention was determined by 3 different methods and stated in the form of distribution coefficients for specific elements. A comparison of the results of vibration and diffusion experiments gave good agreement, while the results in through column experiments only reached the same order of magnitude after an expensive determination with the aid of a place concentration distribution. The distribution coefficients for the elements carbon, selenium, strontium, technetium, iodine, caesium, lead, radium, actinium, proto-actinium, uranium, neptunium, plutonium, americium and curium are listed and collected for model rock packages.

    during androgen therapy is unknown. We retrospectively investigated the possible association between the UGT2B17 gene polymorphism and serum T levels in hypogonadal men during Testosterone undecanoate (TU) substitution therapy. Subjects and Methods: Two hundred and seven patients treated with TU (Nebido......Background: Testosterone (T) is mainly excreted in the urine as testosterone glucuronide (TG). This glucuronidation is partly dependent on the UGT2B17 genotype, and TG excretion is therefore lower in men having the UGT2B17 deletion.

  1. Precambrian crustal evolution and Cretaceous–Palaeogene faulting in West Greenland: 207Pb-206Pb dating of magnetite, monazite and allanite in the central and northern Nagssugtoqidian orogen, West Greenland

    Frei, Robert

    2006-12-01

    Full Text Available Pb-isotopic data for magnetite from amphibolites in the Nagssugtoqidian orogen, central West Greenland, have been used to trace their source characteristics and the timing of metamorphism. Analyses of the magnetite define a Pb-Pb isochron age of 1726 ± 7 Ma. The magnetite is metamorphic in origin, and the 1726 Ma age is interpreted as a cooling age through the closing temperature of magnetite at ~600°C. Some of the amphibolites in this study come from the Naternaq supracrustal rocks in the northern Nagssugtoqidian orogen, which host the Naternaq sulphide deposit and may be part ofthe Nordre Strømfjord supracrustal suite, which was deposited at around 1950 Ma ago.Pb-isotopic signatures of magnetite from the Arfersiorfik quartz diorite in the central Nagssugtoqidian orogen are compatible with published whole-rock Pb-isotopic data from this suite; previous work has shown that it is a product of subduction-related calc-alkaline magmatism between 1920 and 1870 Ma. Intrusion of pegmatites occurred at around 1800 Ma in both the central and the northernparts of the orogen. Pegmatite ages have been determined by Pb stepwise leaching analyses of allanite and monazite, and source characteristics of Pb point to an origin of the pegmatites by melting of the surrounding late Archaean and Palaeoproterozoic country rocks. Hydrothermal activity took place after pegmatite emplacement and continued below the closure temperature of magnetite at 1800–1650 Ma. Because of the relatively inert and refractory nature of magnetite, Pb-isotopic measurements from this mineral may be of help to understand the metamorphic evolution of geologicallycomplex terrains.

    This study resumes the discovery of an excess of actinium 227 found around by EL4 nuclear reactor actually in dismantling. The search for the origin of this excess revealed a real inquiry of investigation during three years. Because a nuclear reactor existed in this area a particular attention will have concerned this region. The doubt became the line of conduct to find the answer to the human or natural origin of this excess. Finally and against any evidence, it appears that the origin of this phenomenon was natural, consequence of the particular local geology. The detail of the different investigations is given: search of a possible correlation with the composition of elevations constituent of lanes, search (and underlining) of new sites in the surroundings of the Rusquec pond and the Plouenez station, study of the atmospheric deposits under winds of the nuclear power plant and in the east direction, search of a possible relationship with the gaseous effluents of the nuclear power plant in the past, historical study of radioactive effluents releases in the fifty last years by the analysis of the sedimentary deposits in the Saint-Herbiot reservoir, search of a possible correlation between the excess of actinium 227 and the nuclear power plant activity; search of a possible correlation with a human activity without any relationship with the nuclear activities, search of a correlation with the underground waters, search of a correlation with the geological context, collect of information on the possible transfers in direction of the food chain, determination of the radiological composition of the underground waters ( not perturbed by human activity), search of the cause of an excess of actinium 227 in the old channel of liquid effluents release of the nuclear power plant. The results are given and discussed. And contrary to all expectations the origin of the excess of actinium 227 is completely natural. (N.C.)

The invention includes a method of producing an actinium-225/bismuth-213 product from a material containing thorium-229 and thorium-232. A solution is formed containing nitric acid and the material containing thorium-229 and thorium-232, and iodate is added to form a thorium iodate precipitate. A supernatant is separated from the thorium iodate precipitate and a second volume of nitric acid is added to the thorium iodate precipitate. The thorium iodate precipitate is stored and a decay product comprising actinium-225 and bismuth-213 is generated in the second volume of nitric acid, which is then separated from the thorium iodate precipitate, filtered, and treated using at least one chromatographic procedure. A system for producing an actinium-225/bismuth-213 product is also disclosed.

  15. Behaviour of uranium series radionuclides in surface water (Crouzille, Limousin). Geochemical implications

    Understanding natural radionuclides behaviour in surface water is a required step to achieve uranium mine rehabilitation and preserve water quality. The first objective of this thesis is to determine which are the radionuclides sources in a drinking water reservoir. The second objective is to improve the knowledge about the behaviour of uranium series radionuclides, especially actinium. The investigated site is a brook (Sagnes, Limousin, France) which floods a peat bog contaminated by a former uranium mine and which empties into the Crouzille lake. It allows studying radionuclides transport in surface water and radionuclides retention through organic substance or water reservoir. Radionuclides distribution in particulate, colloidal and dissolved phases is determined thanks to ultra-filtrations. Gamma spectrometry allows measuring almost all natural radionuclides with only two counting stages. However, low activities of 235U series radionuclides impose the use of very low background well-type Ge detectors, such as those of the Underground Laboratory of Modane (France). Firstly, this study shows that no or few radionuclides are released by the Sagnes peat bog, although its radioactivity is important. Secondly, it provides details on the behaviour of uranium series radionuclides in surface water. More specifically, it provides the first indications of actinium solubility in surface water. Actinium's behaviour is very close to uranium's even if it is a little less soluble. (author)

  18. DISSOLVED CONCENTRATION LIMITS OF RADIOACTIVE ELEMENTS

    2005-07-13

    The purpose of this study is to evaluate dissolved concentration limits (also referred to as solubility limits) of elements with radioactive isotopes under probable repository conditions, based on geochemical modeling calculations using geochemical modeling tools, thermodynamic databases, field measurements, and laboratory experiments. The scope of this activity is to predict dissolved concentrations or solubility limits for elements with radioactive isotopes (actinium, americium, carbon, cesium, iodine, lead, neptunium, plutonium, protactinium, radium, strontium, technetium, thorium, and uranium) relevant to calculated dose. Model outputs for uranium, plutonium, neptunium, thorium, americium, and protactinium are provided in the form of tabulated functions with pH and log fCO{sub 2} as independent variables, plus one or more uncertainty terms. The solubility limits for the remaining elements are either in the form of distributions or single values. Even though selection of an appropriate set of radionuclides documented in Radionuclide Screening (BSC 2002 [DIRS 160059]) includes actinium, transport of Ac is not modeled in the total system performance assessment for the license application (TSPA-LA) model because of its extremely short half-life. Actinium dose is calculated in the TSPA-LA by assuming secular equilibrium with {sup 231}Pa (Section 6.10); therefore, Ac is not analyzed in this report. The output data from this report are fundamental inputs for TSPA-LA used to determine the estimated release of these elements from waste packages and the engineered barrier system. Consistent modeling approaches and environmental conditions were used to develop solubility models for the actinides discussed in this report. These models cover broad ranges of environmental conditions so they are applicable to both waste packages and the invert.

    2015-10-01

    We reported our preliminary results on the use of laser-induced breakdown spectroscopy to analyze the rare earth elements contained in ash samples from Powder River Basin sub-bituminous coal (PRB-coal). We have identified many elements in the lanthanide series (cerium, europium, holmium, lanthanum, lutetium, praseodymium, promethium, samarium, terbium, ytterbium) and some elements in the actinide series (actinium, thorium, uranium, plutonium, berkelium, californium) in the ash samples. In addition, various metals were also seen to present in the ash samples

  1. The identification of soil radionuclides in the area of Puspiptek and surrounding

    The area of PUSPIPTEK and the surrounding are potentially exposed by radionuclides, because the operation of the nuclear research plant. The PPTN Serpong was operated long than 10 years, therefore soil radioactivity need to evaluate. The determination of radioactivity in the soil samples which be taken from research location using gamma spectrometry on June-August. The result of the research identified natural radionuclides K-40; Thorium decay series Ac-228, Bi-212, Pb-212, Tl-208, Ra-224 and Rn-220; Uranium decay series Bi-214, Pa-234, Pb-214 and Actinium decay series Bi-211, Po-211. There are no identification radionuclides produce from the activation of PPTN Serpong

  2. An aerial radiological survey of the Sandia National Laboratories and surrounding area

    A team from the Remote Sensing Laboratory conducted an aerial radiological survey of the area surrounding the Sandia National Laboratories and Kirtland Air Force Base in Albuquerque, New Mexico, during March and April 1993. The survey team measured the terrestrial gamma radiation at the site to determine the levels of natural and man-made radiation. This survey includes the areas covered by a previous survey in 1981. The results of the aerial survey show a background exposure rate which varies between 5 and 18 μR/h plus an approximate 6 μR/h contribution from cosmic rays. The major radioactive isotopes found in this survey were: potassium-40, thallium-208, bismuth-214, and actinium-228, which are all naturally-occurring isotopes, and cobalt-60, cesium-137, and excess amounts of thallium-208 and actinium-228, which are due to human actions in the survey area. In regions away from man-made activity, the exposure rates inferred from this survey's gamma ray measurements agree almost exactly with the exposure rates inferred from the 1981 survey. In addition to the aerial measurements, another survey team conducted in situ and soil sample radiation measurements at three sites within the survey perimeter. These ground-based measurements agree with the aerial measurements within ± 5%

  3. Mixed valency of the RE and Ac ions in solid states

    Full text: This review is devoted to consideration of the methods and results of the theoretical and experimental investigations of the electronic state of the rare earths and actinium ions in the separate compound. The methods of the high resolution X ray spectroscopy were used for our consideration. Energy of the X ray lines of the rare earths and actinium ions in free state and solid states was study carefully. Valency shifts of X Ray lines under change of electronic state of nf - ions in different oxide, fluoride and chloride compounds were determined for K -, L- and M - lines for these ions with accuracy near 10 -100 MeV. We studied the electronic state of nf- ions which is changed from '+2' to '+4' and determined the concentration of ions in different electronic state. Relative error for theoretical energy of the most lines for HFP - approach in comparison with experiment is less than 0.5%, and deviation for concentration is less than 5%

  4. A study of uranium and thorium migration at the Koongarra uranium deposit with application to actinide transport from nuclear waste repositories

    One way to gain confidence in modelling possible radionuclide releases is to study natural systems which are similar to components of the multibarrier waste repository. Several such analogues are currently under study and these provide useful data about radionuclide behaviour in the natural environment. One such system is the Koongarra uranium deposit in the Northern Territory. In this dissertation, the migration of actinides, primarily uranium and thorium, has been studied as an analogue for the behaviour of transuranics in the far-field of a waste repository. The major findings of this study are: 1. the main process retarding uranium migration in the dispersion fan at Koongarra is sorption, which suppresses dissolved uranium concentrations well below solubility limits, with ferrihydrite being a major sorbing phase; 2. thorium is extremely immobile, with very low dissolved concentrations and corresponding high distribution ratios for 230Th. Overall, it is estimated that colloids are relatively unimportant in Koongarra groundwater. Uranium migrates mostly as dissolved species, whereas thorium and actinium are mostly adsorbed to larger, relatively immobile particles and the stationary phase. However, of the small amount of 230Th that passes through a 1μm filter, a significant proportion is associated with colloidal particles. Actinium appears to be slightly more mobile than thorium and is associated with colloids to a greater extent, although generally present in low concentrations. These results support the possibility of colloidal transport of trivalent and tetravalent actinides in the vicinity of a nuclear waste repository. 112 refs., 23 tabs., 32 figs

    Full Text Available Cerium, neodymium and gadolinium contain double beta active isotopes. The most interesting are 150Nd and 160Gd (promising for 0ν2β search, 136Ce (2β+ candidate with one of the highest Q2β. The main problem of compounds containing lanthanide elements is their high radioactive contamination by uranium, radium, actinium and thorium. The new generation 2β experiments require development of methods for a deep purification of lanthanides from the radioactive elements. A combination of physical and chemical methods was applied to purify cerium, neodymium and gadolinium. Liquid-liquid extraction technique was used to remove traces of Th and U from neodymium, gadolinium and for purification of cerium from Th, U, Ra and K. Co-precipitation and recrystallization methods were utilized for further reduction of the impurities. The radioactive contamination of the samples before and after the purification was tested by using ultra-low-background HPGe gamma spectrometry. As a result of the purification procedure the radioactive contamination of gadolinium oxide (a similar purification efficiency was reached also with cerium and neodymium oxides was decreased from 0.12 Bq/kg to 0.007 Bq/kg in 228Th, from 0.04 Bq/kg to <0.006 Bq/kg in 226Ra, and from 0.9 Bq/kg to 0.04 Bq/kg in 40K. The purification methods are much less efficient for chemically very similar radioactive elements like actinium, lanthanum and lutetium.

    Full Text Available This study investigates the level of technological enhancement of normally occurring radioactive materials (TENORM in the red mud waste due to the production of alumina in Jamaica. Technological enhancements factors (TEF were determined for the uranium, thorium, actinium series, their progenies, and the nonseries potassium-40 using gamma spectrometry. The study concluded that bauxite production technologically enhances the uranium progenies Th-234, Pb-214, Bi-214, and Pa-234 and the thorium-232 progenies Ac-228, Pb-212, and Bi-212 in red mud. The actinium series was technologically enhanced, but K-40 and the thorium daughter, Tl-208, were reduced. The spectrometric comparison of Tl-208 (at 510 keV was unexpected since its other photopeaks at 583 keV, 934 keV, and 968 keV were markedly different. An explanation for this anomaly is discussed. An explanation regarding the process of accumulation and fractionation of organically derived phosphate deposits and potassium-feldspar is offered to explain the spectrometric differences between the alumina product and its waste material, red mud.

    Full Text Available The aim of this article is to present Sign Language Translators and Interpreters (SLTIs using current reflections and traditional longstanding concepts of the profession. Even locating interpreters of oral languages and of sign languages in the same chronological line, one should note the significant and clear differences between the two. Based on Rodrigues and Burgos (2001, and on the experiences of Brazilian SLTIs, we outline and highlight the characteristics that differentiate professionals working specifically with oral language from those in SLTI. It is important to mention that the result of the linguistic modality of signed language means that the competence of the SLTI appears to be invisible, thus making it difficult for professionals in this field to be recognized. It is very common for SLTIs to be understood as simply collaborators or facilitators of communication, while the reality is that the functions of the SLTI are much more extensive. By having to deal with the peculiarities of sign language, the SLTI needs to acquire some of its fundamental elements and have exhaustive experience at the frontier of two cultures, as well as bearing responsibilities that are elements in the construction of his or her subjectivity. By presenting questions to those who operate in this field, we highlight the difficulties found in their experiences with the language, with the practice of translating and interpreting, and above all, with the hearing impaired community. We highlight the educational routes that these SLTIs have taken to become professionals in order to guarantee their visibility.

    Full Text Available Objective – To determine primary type, format, language and subject category of research materials used by U.S. scholars of international relations. Also, to investigate whether research method, qualitative or quantitative, can be correlated with the type and age of sources that scholars use.Design – Citation analysis.Setting – Research articles published in three journals on international relations with high impact factors: International Organization, International Studies Quarterly, and World Politics.Subjects – A random sample of cited references taken from the 410 full‐length research articles published in these journals from 2000 to 2005. Cited references of articles written by authors of foreign institutions (i.e., non‐American institutions, as well as cited references of editorial and research notes, comments, responses, and review essays were excluded.Methods – Cited references were exported from ISI’s Social Science Citation Index (SSCI to MS Excel spreadsheets for analysis. Data was verified against original reference lists. Citations were numbered and identified by source format, place of publication (foreign or domestic, age, and language used, if other than English. The author used a random number generator to select a random sample of 651 from a total of 29,862 citations. Citations were randomly drawn from each journal according to the proportion of the journals’ citations to the total. These citations were analyzed by material type and language. The author also used the Library of Congress Classification Outline to identify the subject category of each book and journal citation in the sample. A separate sampling method was used to investigate if there is a relationship between research methodology and citation behaviour. Each of the original 410 articles was categorized according to research method: quantitative, qualitative or a combination of the two. Two articles representing qualitative research and two representing quantitative research were randomly selected from each of the three journals for each of the six years. Subsequently, five citations from each of the resulting pool of 72 articles were randomly selected to create a sample of 360 citations. These citations were analyzed by material type and age of source.Main Results – Analysis of the citation data showed that books (including monographs, edited books, book chapters and dictionaries made up 48.2% of the total citations; journals (including scholarly and non‐scholarly titles made up 38.4% of the citations; and government publications made up 4.5% of the citations. Electronic resources, which primarily refer to Web sites and digital collections in this study, represented 1.7% of the citations. Other sources of citations included magazines (1.1%, newspapers (1.1%, working papers (1.1%, theses (0.9%, conference papers not yet published as articles (0.6%, and a miscellaneous category, which included items such as committee minutes, radio broadcasts, unpublished materials and personal communications (2.5%. The average age of book citations was 14.3 years and the median age was 8 years. Foreign language citations represented 3.7% of the 651 total citations. The top ranked foreign languages were German (7, French (5, Russian (4, Spanish (3, Korean (2 and Swedish (number not given. Subject analysis of the citations revealed that 38% of all citations were from international relations and two related disciplines, political science, political theory, and public administration. Subject areas outside international relations included social sciences (23.4% ‐ including economics, commerce, industries and finance, history (16.3%, sociology (6.2%, and law (5.9%. Citations from philosophy, psychology, military science and general works together made up 7.3% of the total citations. Citations from science, linguistics, literature, geography and medicine made up less than 2% of the total.Authors of qualitative research articles were more likely to cite books (56.7% than journals (29.4% while authors of quantitative research articles were more likely to cite journals (58.3% than books (28.9%. Authors of qualitative research articles were also more likely to cite government publications and electronic resources than those of quantitative articles. However, authors of quantitative research articles were more likely to cite other materials, such as dissertations, conference papers, working papers and unpublished materials.The age of cited materials for both qualitative and quantitative research articles is similar. Citations to recent materials up to 5 years old were most frequent, followed by materials 6 to 10 years old, materials 11 to 15 years old, and those 26 or more years old. The least frequently cited materials were 16 to 20 and 21 to 25 years old.Conclusion – Scholars in international relations primarily cite books, followed by journals and government publications. Citations to electronic resources such as Web sites and digital collections, and to other materials are far less common. Scholars primarily cite English‐language materials on international relations and related subjects. Authors of qualitative research articles are more likely to cite books than journals, while authors of quantitative research articles are more likely to cite journals than books. Recent materials are more frequently cited than older materials, though materials that are more than 26 years old are still being cited regularly.

  13. Purification system of gram-amount neptunium using anion exchange chromatography

    To develop a purification system of gram-amount neptunium using anion exchange chromatography, adsorption elution of excess amount of actinium in 6M HNO3 aqueous solution was studied using thorium and uranium tracer. The partition coefficient (Kd) of Th (IV) decreased from Kd=99.1 of tracer to Kd=44.0, 5% load. By decreasing the partition coefficient, we can wash until 30 Vs under the purification conditions of 1% load and 95% recovery. The retention volume of U (IV) was about 300 Vs, a large value. The partition coefficient of Np (IV) may be larger than it and the large amount of washable eluting solution may be obtained. Washing of impurity of 3d transition metal and actinide (VI) can be done until 20Vs. With washing of 150Vs, impurity of alkali earth metal, metals (III) and platinum group metals decreased less than 0.1%. (S.Y.)

  14. Radionuclide interactions with marine sediments

    A critical review of the literature on the subject of the interactions of radionuclides with marine sediments has been carried out. On the basis of the information available, an attempt has been made to give ranges and 'best estimates' for the distribution ratios between seawater and sediments. These estimates have been based on an understanding of the sediment seawater system and the porewater chemistry and mineralogy. Field measurements, laboratory measurements and estimates based on stable-element geochemical data are all taken into account. Laboratory measurements include distribution-ratio and diffusion-coefficient determinations. The elements reviewed are carbon, chlorine, calcium, nickel, selenium, strontium, zirconium, niobium, technetium, tin, iodine, caesium, lead, radium, actinium, thorium, protactinium, uranium, neptunium, plutonium, americium and curium.

  15. Formerly utilized MED/AEC sites Remedial Action Program. Radiological survey of the St. Louis Airport Storage Site, St. Louis, Missouri. Final report

    Results of two radiological surveys of the St. Louis-Lambert Airport property, formerly known as the Airport Storage Site, St. Louis, Missouri, are presented. Uranium- and radium-bearing waste materials were stored from the 1940's to the late 1960's in this area. The surveys included direct measurements of beta-gamma radiation; determination of uranium, actinium, and radium concentrations in soil samples and from bore holes; determination of radionuclide concentrations in groundwater and surface water; measurement of radon flux from the ground surface; and measurements of 222Rn in air near the site. Results indicate that some offsite drainage pathways are becoming contaminated, probably by runoff from the site; no migration of 222Rn from the site was observed

  16. JAEA thermodynamic database for performance assessment of geological disposal of high-level and TRU wastes. Refinement of thermodynamic data for trivalent actinoids and samarium

    Within the scope of the JAEA thermodynamic database project for performance assessment of geological disposal of high-level radioactive and TRU wastes, the refinement of the thermodynamic data for the inorganic compounds and complexes of trivalent actinoids (actinium(III), plutonium(III), americium(III) and curium(III)) and samarium(III) was carried out. Refinement of thermodynamic data for these elements was based on the thermodynamic database for americium published by the Nuclear Energy Agency in the Organisation for Economic Co-operation and Development (OECD/NEA). Based on the similarity of chemical properties among trivalent actinoids and samarium, complementary thermodynamic data for their species expected under the geological disposal conditions were selected to complete the thermodynamic data set for the performance assessment of geological disposal of radioactive wastes.

  17. Theoretical Study on Properties of New Isotope 265Bh

    2006-01-01

    The properties of nuclei belonging to the newly observed α-decay chain starting from 265Bh have been studied. The axially deformed relativistic mean-field calculation with the force NL-Z2 has been performed in the blockedBCS approximation. Some ground state properties such as binding energies, deformations, spins, and parities, as well as Q-values of the α-decay for this decay chain have been calculated and compared with known experimental data. Good agreement is found. The single-particle spectrum of the nucleus 265 Bh is studied and some new magic numbers are found,while the magnitudes of the shell gaps in superheavy nuclei are much smaller than those of nuclei before the actinium region, and the Fermi surfaces are close to the continuum. Thus the superheavy nuclei are usually not stable. The The methods which give good agreement with the data are selected.

  18. Proposed training program for construction personnel involved in remedial action work at sites contaminated by naturally occurring radionuclides

    Many sites used during the early days of the US atomic energy program are contaminated with radionuclides of the primordial decay chains (uranium, thorium, and actinium series). This contamination consists of residues resulting from refining and processing uranium and thorium. Preparation of these sites for release to unrestricted private use will involve the assistance of construction workers, many of whom have limited knowledge of the hazards associated with radioactive materials. Therefore, there is a need to educate these workers in the fundamentals of radioactive material handling to minimize exposures and possible spread of contamination. This training should disseminate relevant information at an appropriate educational level and should instill a cautious, common-sense attitude toward the handling of radioactive materials. The training should emphasize basic information concerning environmental radiation within a context of relative risk. A multi-media format, including colorful visual aids, demonstration, and discussion, should be used to maximize motivation and retention. A detailed, proposed training program design is presented

    In a previous study which concerned the catchment basin of the harbour of Brest, the A.C.R.O. put in evidence a marking by artificial radioelements around the power plant of Brennilis which can be imputed without ambiguities to the nuclear installation. It also put in evidence abnormalities concerning the natural radioactivity which justifies this new study. In the area of the Monts d'Arree, actinium 227 ({sup 227}Ac), non born by its ascendents which are {sup 235}U and {sup 231}Pa is observed. This phenomenon is characterized by mass activities superior to these ones of {sup 235}U and able to reach these ones of {sup 238}U. Its presence corresponds with the drainage of the Ellez river since the former channel of radioactive effluents releases from the nuclear power plant EL-4 up to the reservoir Saint-Herblot situated 6 km downstream. The strongest values of radioactivity are registered near the disused power plant, at this place a relationship exists between the level of actinium 227 and this one of the artificial radioactivity as it exists a relationship with the decay products of radon exhaled from the subsoil ({sup 210}Pb). But its presence is not limited to a part of the Ellez river, it is equally observed in terrestrial medium, in places in priori not influenced by the direct liquid effluents of the power plant. This place is situated at more than 4 km and without any connection with the Ellez waters. At this stage of the study, it is not possible to answer with certainty the question of the origin of this phenomenon. A new reorientation is considered indispensable to clarify definitively the origin of this unknown phenomenon in the scientific publications and the environmental monitoring. (N.C.)

  1. Physical Measurements and Clinical Findings of Persons with Radium Burdens

    Results of physical measurements and some clinical findings of persons with radium burdens are reported and discussed. Ten workers of the dial painting industry, two chemists, who have been working for between 10 and 20 yr in the radium- industry, one technician, who has been- working for over 20 yr with high-emanation radium preparations and one person with high radium intake of rather unknown history were measured in a whole-body counter for evaluation of the body burdens of radium-226 and radium-228+ actinium-228. In some cases the radon concentration of expired air was also measured. For four of the measured persons the radium-226 burden is of the order of the maximum permissible amount (MPA : 10-7 c) or more. In one case the burden amounts to more than three times the MPA, (3.4 x 10-7 c), in another case to more than 100 times the MPA (160 x 10-7 c). In one case the radium-228 + actinium-228 burden exceeds the MPA (6 x 10-8 c in bone). The measured radon concentrations in the expired air were used to calculate the excretion rate of radon. The average was 67%. Clinical findings with some of the measured persons are related to the measured body burdens. The patient with the high body burden of 160 x 10-7 c radium-226 shows heavy bone changes leading to spontaneous bone fractures. The blood picture shows a decrease in the number of erythrocytes and a low haemoglobin content but puncture of the sternum indicates normal haematopoiesis. It seems that the low number of erythrocytes is caused by chronic nephropathia, the reason for which might be an additional intake of uranium because.uranium was found in the urine by gamma spectroscopy. The results are discussed with respect to the MPA of radium-226 recommended by the International Commission on Radiological Protection. (author)

  2. Historical trends in the lead isotopic composition of archival Sphagnum mosses from Scotland (1838-2000).

    Farmer, John G; Eades, Lorna J; Atkins, Hannah; Chamberlain, David F

    2002-01-15

    The analysis of almost 200 Scottish Sphagnum moss samples collected over the past 170 years has revealed trends in the isotopic composition of lead similar to those previously established for dated Scottish lake sediments and peat bogs, lending credibility to these proxy records of atmospheric lead contamination and deposition. The effect of temporal variations in contributions from sources such as smelting of indigenous lead ores (206Pb/207Pb approximately 1.16-1.18), coal combustion (206Pb/207Pb approximately 1.17-1.19), and the use of imported Australian lead (206Pb/207Pb approximately 1.04) was clearly seen in the Scottish moss 206Pb/207Pb record. This showed some differences from the corresponding archival herbage record for the south of England, where the initial influence of Australian lead occurred earlier, at the end of the 19th century. A significant decline from a 206Pb/ 207Pb value of approximately 1.17 in the Scottish moss record began in the 1920s and continued until the 1980s (206Pb/207Pb approximately 1.12). The success of measures to reduce lead emissions to the atmosphere over the past 20 years in the U.K., in particular from petrol-engined vehicles using alkyl lead additives manufactured primarily from Australian lead, is evident in both the increasing 206Pb/207Pb ratio and falling lead concentration data for Scottish moss.
