Sample records for bohrium 260

  1. From bohrium to copernicium and beyond SHE research at SHIP

    Science.gov (United States)

    Münzenberg, G.

    2015-12-01

    Heavy-element research with SHIP at GSI is reviewed including the discovery of the chemical elements bohrium to copernicium, experimental developments, cold fusion of heavy ions, and the discovery of a shell region around hassium. Elements bohrium and heavier are located beyond the limit of liquid-drop stability. They exist by shell stabilization. A universal, sensitive, and fast method: in-flight separation and identification of single atomic nuclei has been developed with the velocity filter SHIP and the detector system to measure decay sequences of individual atoms. Research with single atomic nuclei including detection methods, identification, and physics results will be discussed. Experiments with actinide targets as well as prospects with NUSTAR at FAIR will be addressed.

  3. Properties of an $\\alpha$ particle in a Bohrium $270$ Nucleus under the Generalized Symmetric Woods-Saxon Potential

    CERN Document Server

    Lütfüoğlu, B C

    2016-01-01

    The energy eigenvalues and the wave functions of an $\\alpha$ particle in a Bohrium $270$ nucleus were calculated by solving Schr\\"odinger equation for Generalized Symmetric Woods-Saxon potential. Using the energy spectrum by excluding and including the quasi-bound eigenvalues, entropy, internal energy, Helmholtz energy, and specific heat, as functions of reduced temperature were calculated. Stability and emission characteristics are interpreted in terms of the wave and thermodynamic functions. The kinetic energy of a decayed $\\alpha$ particle was calculated using the quasi-bound states, which is found close to the experimental value.

  15. Odd-Z Transactinide Compound Nucleus Reactions Including the Discovery of 260Bh

    International Nuclear Information System (INIS)

    Several reactions producing odd-Z transactinide compound nuclei were studied with the 88-Inch Cyclotron and the Berkeley Gas-Filled Separator at the Lawrence Berkeley National Laboratory. The goal was to produce the same compound nucleus at or near the same excitation energy with similar values of angular momentum via different nuclear reactions. In doing so, it can be determined if there is a preference in entrance channel, because under these experimental conditions the survival portion of Swiatecki, Siwek-Wilcznska, and Wilczynski's 'Fusion By Diffusion' model is nearly identical for the two reactions. Additionally, because the same compound nucleus is produced, the exit channel is the same. Four compound nuclei were examined in this study: 258Db, 262Bh, 266Mt, and 272Rg. These nuclei were produced by using very similar heavy-ion induced-fusion reactions which differ only by one proton in the projectile or target nucleus (e.g.: 50Ti + 209Bi vs. 51V + 208Pb). Peak 1n exit channel cross sections were determined for each reaction in each pair, and three of the four pairs; cross sections were identical within statistical uncertainties. This indicates there is not an obvious preference of entrance channel in these paired reactions. Charge equilibration immediately prior to fusion leading to a decreased fusion barrier is the likely cause of this phenomenon. In addition to this systematic study, the lightest isotope of element 107, bohrium, was discovered in the 209Bi(52Cr,n) reaction. 260Bh was found to decay by emission of a 10.16 MeV alpha particle with a half-life of 35 ms. The cross section is 59 pb at an excitation energy of 15.0 MeV. The effect of the N = 152 shell is also seen in this isotope's alpha particle energy, the first evidence of such an effect in Bh. All reactions studied are also compared to model predictions by Swiatecki, Siwek-Wilcznska, and Wilczynski's 'Fusion By Diffusion' theory

    We investigate the collinear ternary fission of the 260No isotope. The calculations are performed in the framework of the three cluster model for all possible accompanied light particles of even mass numbers A = 4 - 52. The folding nuclear and Coulomb interaction potentials are used, based on the M3Y-Reid nucleon-nucleon force for the nuclear part. The deformation of the involved fragments and their relative orientations with respect to each other inside the fissioning nuclei are considered. Among all possible fragmentation channels, the suggested most probable channels are indicated as the ones showing a peak in the Q-value and a local minimum in the fragmentation potential, with respect to the mass and charge asymmetries. The indicated favored fragmentation channels from the approximate spherical calculations and those obtained after considering the deformations of the produced fragments are discussed in detail. In addition to the preferred heavy fragments of closed shells, favored prolate ones of high deformations appear when the nuclear deformations are taken into account. Among indicated fifty six favored channels, a collinear ternary fission of the 260No isotope is indicated to be most favored through the fragmentation channels of 15058Ce+410Be+40100Zr,60152Nd+412Be+3896Sr,58150Ce+614C+3896Sr,58148Ce+616C+3896Sr,54140Xe+822O+4098Zr,42106Mo+1848Ar+42106Mo and 41104Nb+2052Ca+41104Nb.

  9. Amplifier Module for 260-GHz Band Using Quartz Waveguide Transitions

    2012-01-01

    Packaging of MMIC LNA (monolithic microwave integrated circuit low-noise amplifier) chips at frequencies over 200 GHz has always been problematic due to the high loss in the transition between the MMIC chip and the waveguide medium in which the chip will typically be used. In addition, above 200 GHz, wire-bond inductance between the LNA and the waveguide can severely limit the RF matching and bandwidth of the final waveguide amplifier module. This work resulted in the development of a low-loss quartz waveguide transition that includes a capacitive transmission line between the MMIC and the waveguide probe element. This capacitive transmission line tunes out the wirebond inductance (where the wire-bond is required to bond between the MMIC and the probe element). This inductance can severely limit the RF matching and bandwidth of the final waveguide amplifier module. The amplifier module consists of a quartz E-plane waveguide probe transition, a short capacitive tuning element, a short wire-bond to the MMIC, and the MMIC LNA. The output structure is similar, with a short wire-bond at the output of the MMIC, a quartz E-plane waveguide probe transition, and the output waveguide. The quartz probe element is made of 3-mil quartz, which is the thinnest commercially available material. The waveguide band used is WR4, from 170 to 260 GHz. This new transition and block design is an improvement over prior art because it provides for better RF matching, and will likely yield lower loss and better noise figure. The development of high-performance, low-noise amplifiers in the 180-to- 700-GHz range has applications for future earth science and planetary instruments with low power and volume, and astrophysics array instruments for molecular spectroscopy. This frequency band, while suitable for homeland security and commercial applications (such as millimeter-wave imaging, hidden weapons detection, crowd scanning, airport security, and communications), also has applications to

    2010-01-01

    We performed an optical/infrared study of the counterpart of the low-mass X-ray binary KS1731-260 to test its identification and obtain information about the donor. Optical and infrared images of the counterpart of KS1731-260 were taken in two different epochs (2001 and 2007) after the source returned to quiescence in X-rays. We compared those observations with obtained when KS 1731-260 was still active. We confirm the identification of KS1731-260 with the previously proposed counterpart and improve its position to RA=17:34:13.46 and DEC=-26:05:18.60. The H-band magnitude of this candidate showed a decline of ~1.7 mags from outburst to quiescence. In 2007 April we obtained R=22.8+-0.1 and I=20.9+-0.1 for KS1731-260. Similar optical brightness was measured in June 2001 and July 2007. The intrinsic optical color R-I is consistent with spectral types from F to G for the secondary although there is a large excess over that from the secondary at the infrared wavelengths. This may be due to emission from the cooler...

  12. "Tonalism": Name, Soul, Destiny and Identity Determined by the 260-Day Calendar in Mesoamerica

    Directory of Open Access Journals (Sweden)

    Lars Kirkhusmo Pharo

    2012-08-01

    Full Text Available In various Mesoamerican cultures, i.e. civilisations of Middle America, a calendar name is part of the antroponym. Besides having conventional personal names, both human beings and deities carry day-names from the 260-day calendar. In addition, world ages or world periods, periods of the traditional 365-day calendar and the 52-year calendar as well as the cardinal directions of the quadripartite world were categorised by day-names of the 260-day calendar. Thus not only human and divine beings but also space and time received designations from this calendar. Moreover, this onomastic practice of giving personal names from day signs of the 260-day calendar - called "tonalism" (from Nahuatl - is related to the Mesoamerican concepts of destiny and to what is known in history of religions as the "freesoul". Consequently, this anthropnymic tradition provides identity to human, divine beings and spatial-temporal phenomena.

    To examine whether genes that predispose to schizophrenia also confer a predisposition to other psychiatric disorders such as bipolar affective disorder (BAD), we tested for linkage between the recently identified schizophrenia susceptibility locus D6S260 and the inheritance of BAD in 12 large Australian pedigrees. We found no evidence for linkage over a region of 12-27 cM from the D6S260 locus, depending on the model used. Our results therefore do not provide support for the continuum theory of psychosis. 13 refs., 2 tabs.

  7. Neutron emission as a function of fragment energy in the spontaneous fission of 260Md

    International Nuclear Information System (INIS)

    The authors have made the first measurement of the number of neutrons emitted in the spontaneous fission of a nuclide in which very high fragment energies dominate the fission process. In bombardments of 254Es, they produced 28-d 260Md, which was neutron-counted in a 1-m-diam spherical tank containing a Gd-doped scintillator solution. The average number of neutrons emitted per fission is only 2.58 ± 0.11, substantially less than for other actinides. A direct correlation of neutron multiplicity with fragment excitation energy is clearly demonstrated

  8. Demonstration of New Technologies Required for the Treatment of Mixed Waste Contaminated with {ge}260 ppm Mercury

    Energy Technology Data Exchange (ETDEWEB)

    Morris, M.I.

    2002-02-06

    The Resource Conservation and Recovery Act (RCRA) defines several categories of mercury wastes, each of which has a defined technology or concentration-based treatment standard, or universal treatment standard (UTS). RCRA defines mercury hazardous wastes as any waste that has a TCLP value for mercury of 0.2 mg/L or greater. Three of these categories, all nonwastewaters, fall within the scope of this report on new technologies to treat mercury-contaminated wastes: wastes as elemental mercury; hazardous wastes with less than 260 mg/kg [parts per million (ppm)] mercury; and hazardous wastes with 260 ppm or more of mercury. While this report deals specifically with the last category--hazardous wastes with 260 ppm or more of mercury--the other two categories will be discussed briefly so that the full range of mercury treatment challenges can be understood. The treatment methods for these three categories are as follows: Waste as elemental mercury--RCRA identifies amalgamation (AMLGM) as the treatment standard for radioactive elemental mercury. However, radioactive mercury condensates from retorting (RMERC) processes also require amalgamation. In addition, incineration (IMERC) and RMERC processes that produce residues with >260 ppm of radioactive mercury contamination and that fail the RCRA toxicity characteristic leaching procedure (TCLP) limit for mercury (0.20 mg/L) require RMERC, followed by AMLGM of the condensate. Waste with <260 ppm mercury--No specific treatment method is specified for hazardous wastes containing <260 ppm. However, RCRA regulations require that such wastes (other than RMERC residues) that exceed a TCLP mercury concentration of 0.20 mg/L be treated by a suitable method to meet the TCLP limit for mercury of 0.025 mg/L. RMERC residues must meet the TCLP value of {ge}0.20 mg/L, or be stabilized and meet the {ge}0.025 mg/L limit. Waste with {ge}260 ppm mercury--For hazardous wastes with mercury contaminant concentrations {ge}260 ppm and RCRA

    Crustal cooling of accretion-heated neutron stars provides insight into the stellar interior of neutron stars. The neutron star X-ray transient, KS 1731-260, was in outburst for 12.5 years before returning to quiescence in 2001. We have monitored the cooling of this source since then through Chandra and XMM-Newton observations. Here, we present a 150 ks Chandra observation of KS 1731-260 taken in August 2015, about 14.5 years into quiescence, and 6 years after the previous observation. We find that the neutron star surface temperature is consistent with the previous observation, suggesting that crustal cooling has likely stopped and the crust has reached thermal equilibrium with the core. Using a theoretical crust thermal evolution code, we fit the observed cooling curves and constrain the core temperature (T$_c = 9.35\\pm0.25\\times10^7$ K), composition (Q$_{imp} = 4.4^{+2.2}_{-0.5}$) and level of extra shallow heating required (Q$_{sh} = 1.36\\pm0.18$ MeV/nucleon). We find that the presence of a low thermal co...

    Full Text Available BACKGROUND: The gene encoding CD14 has been proposed as an IBD-susceptibility gene with its polymorphism C-260T being widely evaluated, yet with conflicting results. The aim of this study was to investigate the association between this polymorphism and IBD by conducting a meta-analysis. METHODOLOGY/PRINCIPAL FINDINGS: Seventeen articles met the inclusion criteria, which included a total of 18 case-control studies, including 1900 ulcerative colitis (UC cases, 2535 Crohn's disease (CD cases, and 4004 controls. Data were analyzed using STATA software. Overall, association between C-260T polymorphism and increased UC risk was significant in allelic comparison (odds ratio [OR]  =1.21, 95% confidence interval [CI]: 1.02-1.43; P=0.027, homozygote model (OR  =1.44, 95% CI: 1.03-2.01; P=0.033, as well as dominant model (OR  =1.36, 95% CI: 1.06-1.75; P=0.016. However, there was negative association between this polymorphism and CD risk across all genetic models. Subgroup analyses by ethnicity suggested the risk-conferring profiles of -260T allele and -260 TT genotype with UC in Asians, but not in Caucasians. There was a low probability of publication bias. CONCLUSIONS/SIGNIFICANCE: Expanding previous results of individual studies, our findings demonstrated that CD14 gene C-260T polymorphism might be a promising candidate marker in susceptibility to UC, especially in Asians.

    Claystone beds directly below and above the Emeishan basalts in SW China formed around the Guadalupian-Lopingian (G - L) boundary. Zircons from both levels give U-Pb ages of ~ 260 Ma, and are identical within-error to ages reported for the Emeishan Large Igneous Province (LIP). The claystones lack Nb - Ta anomalies on primitive mantle normalized elemental diagrams; zircons from these claystones have a geochemical affinity to within-plate-type magmas. These features, combined with the strong negative Eu anomalies in the zircons and high Al2O3/TiO2 ratios, indicate that claystones around the G - L boundary have a silicic volcanic component related to Emeishan LIP. Zircons from the underlying claystone bed have much higher U/Yb and Th/Nb ratios and lower εHf(t) values than those overlying the LIP, suggesting that early-stage silicic volcanic rocks had a higher crustal contamination or assimilation during magmatic processes. In terms of stratigraphic correlation, our data demonstrate that silicic eruptions occurred not only at the end, but also at the beginning of the Emeishan LIP, and the overall duration of the main basaltic phase was short (y).

    We investigate interaction effects on the dynamics and morphology of the galaxy pairs AM\\,2058-381 and AM\\,1228-260. This work is based on $r'$ images and long-slit spectra obtained with the Gemini Multi-Object Spectrograph at the Gemini South Telescope. The luminosity ratio between the main (AM\\,2058A) and secondary (AM\\,2058B) components of the first pair is a factor of $\\sim$ 5, while for the other pair, the main (AM\\,1228A) component is 20 times more luminous than the secondary (AM\\,1228B). The four galaxies have pseudo-bulges, with a S\\'ersic index $n<2$. Their observed radial velocities profiles (RVPs) present several irregularities. The receding side of the RVP of AM\\,2058A is displaced with respect to the velocity field model, while there is a strong evidence that AM\\,2058B is a tumbling body, rotating along its major axis. The RVPs for AM\\,1228A indicate a misalignment between the kinematic and photometric major axes. The RVP for AM\\,1228B is quite perturbed, very likely due to the interaction wit...

    We report above-ground biomass (AGB), basal area, stem density and wood mass density estimates from 260 sample plots (mean size: 1.2 ha) in intact closed-canopy tropical forests across 12 African countries. Mean AGB is 395.7 Mg dry mass ha−1 (95% CI: 14.3), substantially higher than Amazonian values, with the Congo Basin and contiguous forest region attaining AGB values (429 Mg ha−1) similar to those of Bornean forests, and significantly greater than East or West African forests. AGB therefore appears generally higher in palaeo- compared with neotropical forests. However, mean stem density is low (426 ± 11 stems ha−1 greater than or equal to 100 mm diameter) compared with both Amazonian and Bornean forests (cf. approx. 600) and is the signature structural feature of African tropical forests. While spatial autocorrelation complicates analyses, AGB shows a positive relationship with rainfall in the driest nine months of the year, and an opposite association with the wettest three months of the year; a negative relationship with temperature; positive relationship with clay-rich soils; and negative relationships with C : N ratio (suggesting a positive soil phosphorus–AGB relationship), and soil fertility computed as the sum of base cations. The results indicate that AGB is mediated by both climate and soils, and suggest that the AGB of African closed-canopy tropical forests may be particularly sensitive to future precipitation and temperature changes.

    Taking Coulomb and proximity potentials as the interacting barrier we have studied the cold valley in the radioactive decay of 244-260Fm isotopes. It is found that in addition to alpha particle minima, other minima occur at S, Ar and Ca clusters. We have computed the half-lives and other characteristics of different clusters emitted from these parents treating parent, daughter and emitted cluster as spheres. Our study reveals that most of these parents are unstable against alpha and heavy cluster (46Ar, 48,50Ca) emissions and stable against light cluster emission, except 8Be from 244-248Fm isotopes. The most probable clusters from these parents are predicted to be 46Ar, 48,50Ca which indicate the role of doubly or near doubly magic clusters ( = 20, = 28) and also stress the role of doubly magic 208Pb daughter. The computed half-lives for alpha decay are in good agreement with the experimental data. It is found that the presence of neutron excess in the parent nuclei slows down the cluster decay process. The effect of quadrupole (2) and hexadecapole (4) deformations of parent and fragments on half-lives are also studied. It is found that inclusion of 2 and 4 reduces the height and shape of the barrier (increases barrier penetrability) and hence the half-life decreases.

    Hypodontia, a tooth developmental disease, can affect chewing and pronunciation. Mutations in the ectodysplasin-A (EDA) gene can lead to both X-linked hypohidrotic ectodermal dysplasia (XLHED) and non-syndromic hypodontia (NSH). However, the mechanism by which these 2 related but different disorders are caused by the distinct mutations in EDA is unknown. In this study, we identified a novel missense mutation (c.779 T>G) in a Chinese family with NSH via a direct sequencing approach. This mutation results in an Ile260Ser substitution in the tumor necrosis factor (TNF) homology domain. Homology modeling suggests that this alteration may induce a conformational change in the hydrophobic center of the TNF homology domain. Furthermore, by exploring systematic 3D conformation analysis and calculation of residue relative solvent accessibility (RSA) for all the reported mutated amino acid sites on EDA's TNF homology domain, we found that the site mutations at the interior may be linked to XLHED, while those at the surface are more likely to be associated with NSH. These findings may aid in the discovery of unidentified functionally significant mutation sites in the EDA gene and provide a new way to clarify the mechanisms by which the XLHED and NSH phenotypes arise from mutations in the same gene.

    Mercury contaminated wastes in many forms are present at various U. S. Department of Energy (DOE) sites. Based on efforts led by the Mixed Waste Focus Area (MWFA) and its Mercury Working Group (HgWG), the inventory of wastes contaminated with <260 ppm mercury and with radionuclides stored at various DOE sites is estimated to be approximately 6,000 m3). At least 26 different DOE sites have this type of mixed low-level waste in their storage facilities. Extraction methods are required to remove mercury from waste containing >260 ppm levels, but below 260 ppm Hg contamination levels the U. S. Environmental Protection Agency (EPA) does not require removal of mercury from the waste. Steps must still be taken, however, to ensure that the final waste form does not leach mercury in excess of the limit for mercury prescribed in the Resource Conservation and Recovery Act (RCRA) when subjected to the Toxicity Characteristic Leaching Procedure (TCLP). At this time, the limit is 0.20 mg/L. However, in the year 2000, the more stringent Universal Treatment Standard (UTS) of 0.025 mg/L will be used as the target endpoint. Mercury contamination in the wastes at DOE sites presents a challenge because it exists in various forms, such as soil, sludges, and debris, as well as in different chemical species of mercury. Stabilization is of interest for radioactively contaminated mercury waste (<260 ppm Hg) because of its success with particular wastes, such as soils, and its promise of applicability to a broad range of wastes. However, stabilization methods must be proven to be adequate to meet treatment standards. It must also be proven feasible in terms of economics, operability, and safety. To date, no standard method of stabilization has been developed and proven for such varying waste types as those within the DOE complex.

    Radiologically inserted gastrostomy (RIG) is an established way of maintaining enteral nutrition in patients who cannot maintain nutrition orally. The purpose of this study was to evaluate the safety and efficacy of primary placement of a wide bore button gastrostomy in a large, varied patient population through retrospective review. All patients who underwent gastrostomy placement from January 1, 2004 to January 1, 2009 were identified. 18-Fr gastrostomy buttons (MIC-Key G) were inserted in the majority. Follow-up ranged from 6 months to 4.5 years. A total of 260 patients (M:F 140:120, average age 59.2 years) underwent gastrostomy during the study period. Overall success rate for RIG placement was 99.6 %, with success rate of 95.3 % for primary button insertion. Indications included neurological disorders (70 %), esophageal/head and neck malignancy (21 %), and other indications (9 %). Major and minor complication rates were 1.2 and 12.8 %, respectively. Thirty-day mortality rate was 6.8 %. One third of patients underwent gastrostomy reinsertion during the study period, the main indication for which was inadvertent catheter removal. Patency rate was high at 99.5 %. The maximum number of procedures in any patient was 8 (n = 2), and the average tube dwell time was 125 days. Primary radiological insertion of a wide bore button gastrostomy is a safe technique, with high success rate, high patency rate, and low major complication rate. We believe that it is feasible to attempt button gastrostomy placement in all patients, once tract length is within limits of tube length. If difficulty is encountered, then a standard tube may simply be placed instead.

    2011-07-01

    Full Text Available Abstract Background Asthma is a phenotypically diverse disease with genetic susceptibility. A single nucleotide polymorphism (SNP in the CD14 gene at position -260 (also known as -159 C>T has been inconsistently associated with asthma. The aim of this study was to estimate the combined likelihood of developing asthma given the CD14 -260C>T genotype. Methods Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA guidelines, a systematic search and meta-analysis of the literature was conducted to estimate the association between this SNP and asthma. Planned subgroup analyses were performed to detect potential sources of heterogeneity from selected study characteristics. Post-hoc sensitivity analysis was performed to identify studies exerting excessive influence on among-study heterogeneity and combined effects. Results Meta-analysis of 23 studies yielded a non-significant overall association with high heterogeneity across studies. After restricting analysis to studies using atopic asthma and non-atopic non-asthma case-control phenotypes and excluding studies influencing heterogeneity, the genotype-specific odds ratios (ORs suggested a codominant model. Carriers of the TT and CT genotypes were about 33% less likely (OR = 0.67, 95% CI: 0.54-0.84 and about 20% less likely (OR = 0.80, 95% CI: 0.66-0.95, respectively, to have atopic asthma compared to carriers of the CC genotype. Among-study heterogeneity may be explained by overly broad asthma phenotype definitions, gene-environment interactions, and gene-gene interactions. Conclusions A protective dose-response relationship between the CD14 -260T allele and atopic asthma susceptibility was observed. These results demonstrate the importance of precisely specified case-control groups as well as the need to assess interactions in the investigation of complex diseases such as asthma.

    Full Text Available Purpose: In this study, we evaluated the optic performance of Zaraccom UF intraocular lens (IOL by comparing the contrast sensitivity of IOLs in photopic and mesopic lighting conditions in patients who were operated for cataract and inserted Zaraccom Ultraflex (UF or Zaraccom F260 (F260 IOL. Methods: In this prospective study, we included 60 eyes of 60 patients (Group 1: 30 patients UF, Group 2: 30 patients F260 who had undergone phacoemulsification with implantation of IOL in the posterior chamber between 2009 and 2010 in Ophthalmology Department at Cumhuriyet University. The patients were examined routinely at the 1. day, 1. week and 1. month postoperatively. At the third month, the best-corrected visual acuity values were recorded; then,, the contrast sensitivity tests at 1.5, 3, 6, 12 and 18 cpd were examined in all patients in all frequencies in photopic (with and without glare and mesopic (with and without glare lighting conditions. Results: When comparing the contrast sensitivity results in the two groups, we found that UF group’s values were higher in all spatial frequencies (1.5, 3, 6, 12 and 18 cpd. The results were statistically significantly greater for the test frequencies of mesopic without glare 1.5 (p=0.016 and 18 (p=0.005 cpd, mesopic with glare 6 (p=0.002 cpd, photopic without glare 1.5 (p=0.01, 3 (p=0.04, 6 (p=0.001 and 12 (p=0.001 cpd, photopic with glare 6 (p=0.01 and 12 (p=0.02 cpd (p<0.05. Conclusion: These results show that both IOLs provide good level of contrast sensitivity, but better visual perception is achieved with UF IOL. We think that the High Modulation Transfer Function (MTF value of the UF IOL is an important factor for the obtained results. (Turk J Ophthalmol 2011; 41: 230-5

  9. Liver biomarker and in vitro assessment confirm the hepatic origin of aminotransferase elevations lacking histopathological correlate in beagle dogs treated with GABAA receptor antagonist NP260

    International Nuclear Information System (INIS)

    NP260 was designed as a first-in-class selective antagonist of α4-subtype GABAA receptors that had promising efficacy in animal models of pain, epilepsy, psychosis, and anxiety. However, development of NP260 was complicated following a 28-day safety study in dogs in which pronounced elevations of serum aminotransferase levels were observed, although there was no accompanying histopathological indication of hepatocellular injury. To further investigate the liver effects of NP260, we assayed stored serum samples from the 28-day dog study for liver specific miRNA (miR-122) as well as enzymatic biomarkers glutamate dehydrogenase and sorbitol dehydrogenase, which indicate liver necrosis. Cytotoxicity assessments were conducted in hepatocytes derived from dog, rat, and human liver samples to address the species specificity of the liver response to NP260. All biomarkers, except ALT, returned toward baseline by Day 29 despite continued drug treatment, suggesting adaptation to the initial injury. In vitro analysis of the toxicity potential of NP260 to primary hepatocytes indicated a relative sensitivity of dog > human > rat, which may explain, in part, why the liver effects were not evident in the rodent safety studies. Taken together, the data indicate that a diagnostic biomarker approach, coupled with sensitive in vitro screening strategies, may facilitate interpretation of toxicity potential when an adaptive event masks the underlying toxicity. - Highlights: • NP260 caused ALT elevations in dogs without evidence of hepatocellular injury. • SDH, GLDH, and miRNA-122 elevations occurred, confirming hepatocellular necrosis. • NP260 toxicity is greater in dog and human hepatocytes than in rat hepatocytes. • Species sensitivity may explain why the rodent studies failed to indicate risk. • Diagnostic biomarkers and hepatocyte studies aid interpretation of hepatotoxicity

    Within the Unified ternary fission model (UTFM), the alpha accompanied ternary fission of even-even $^{244-260}$Cf isotopes has been studied by taking the interacting barrier as the sum of Coulomb and proximity potential. For the alpha accompanied ternary fission of 244^Cf isotope, the highest yield is obtained for the fragment combination 108^Ru+4^He+132^Te, which contain near doubly magic nuclei 132^Te (N=80, Z=52). In the case of 246^Cf and 248^Cf isotopes, the highest yield is obtained for the fragment combinations with near doubly magic nuclei 134^Te (N=82, Z=52) as the heavier fragment. The highest yield obtained for 250^Cf, 252^Cf, 254^Cf, 256^Cf, 258^Cf and 260^Cf isotopes is for the fragment combination with doubly magic nuclei 132^Sn (N=82, Z=50) as the heavier fragment. We have included the effect of deformation and orientation of fragments and this has revealed that in addition to closed shell effect, ground state deformation also plays an important role in the calculation of relative yield of fav...

    We demonstrated onset of deep-ultraviolet (DUV) surface stimulated emission (SE) from c-plane AlGaN multiple-quantum well (MQW) heterostructures grown on a sapphire substrate by optical pumping at room temperature. The onset of SE became observable at a pumping power density of 630 kW/cm{sup 2}. Spectral deconvolution revealed superposition of a linearly amplified spontaneous emission peak at λ ∼ 257.0 nm with a full width at half maximum (FWHM) of ∼12 nm and a superlinearly amplified SE peak at λ ∼ 260 nm with a narrow FWHM of less than 2 nm. In particular, the wavelength of ∼260 nm is the shortest wavelength of surface SE from III-nitride MQW heterostructures to date. Atomic force microscopy and scanning transmission electron microscopy measurements were employed to investigate the material and structural quality of the AlGaN heterostructures, showing smooth surface and sharp layer interfaces. This study offers promising results for AlGaN heterostructures grown on sapphire substrates for the development of DUV vertical cavity surface emitting lasers (VCSELs)

  12. Neutron star crust cooling in KS 1731-260: the influence of accretion outburst variability on the crustal temperature evolution

    2016-10-01

    Using a theoretical model, we track the thermal evolution of a cooling neutron star crust after an accretion-induced heating period with the goal of constraining the crustal parameters. We present for the first time a crust cooling model - NSCOOL - that takes into account detailed variability during the full outburst based on the observed light curve. We apply our model to KS 1731-260. The source was in outburst for ˜12 yr during which it was observed to undergo variations on both long (years) and short (days-weeks) time-scales. Our results show that KS 1731-260 does not reach a steady state profile during the outburst due to fluctuations in the derived accretion rate. Additionally, long time-scale outburst variability mildly affects the complete crust cooling phase, while variations in the final months of the outburst strongly influence the first ˜40 d of the calculated cooling curve. We discuss the consequences for estimates of the neutron star crust parameters, and argue that detailed modelling of the final phase of the outburst is key to constraining the origin of the shallow heat source.

    We report on generation of 260 fs-short pulses with energy of 1.1 nJ from a fully fiberized, monolithic Tm-doped fiber laser system. The design comprises a simple, graphene-based ultrafast oscillator and an integrated all-fiber chirped pulse amplifier (CPA). The system generates 110 mW of average power at 100.25 MHz repetition rate and central wavelength of 1968 nm. This is, to our knowledge, the highest pulse energy generated from a fully fiberized sub-300 fs Tm-doped laser, without the necessity of using grating-based dispersion compensation. Such compact, robust and cost-effective system might serve as a seed source for nonlinear frequency conversion or mid-infrared supercontinuum generation. PMID:26698769

    Sesquiterpenes are natural products derived from the common precursor farnesyl pyrophosphate (FPP) but are highly diverse in structure and function. Cytochrome P450 enzymes (P450s) exhibit the unique ability to introduce molecular oxygen into non-activated C-H bonds. In plant biosynthetic pathways, P450s commonly derivatize sesquiterpene hydrocarbons. However, the potential of bacterial P450s for terpene derivatization is still underinvestigated. This work compares the substrate specificities and regioselectivities of the sesquiterpene hydroxylases CYP260A1 and CYP264B1 from myxobacterium Sorangium cellulosum So ce56. Four tested substrate classes (eremophilanes, humulanes, caryophyllanes, and cedranes) were converted by both P450s. The achievable variety of oxidations is demonstrated on the model substrates (+)-nootkatone and zerumbone. Increasing the number of functionally investigated P450s, this study represents a step towards the selective derivatization of sesquiterpenes. PMID:26449371

    International Nuclear Information System (INIS)

    A new experimental setup for reliable measurement of the in-plane Seebeck coefficient of organic and inorganic thin films and bulk materials is reported. The system is based on the “Quasi-Static” approach and can measure the thermopower in the range of temperature between 260 K and 460 K. The system has been tested on a pure nickel bulk sample and on a thin film of commercially available PEDOT:PSS deposited by spin coating on glass. Repeatability within 1.5% for the nickel sample is demonstrated, while accuracy in the measurement of both organic and inorganic samples is guaranteed by time interpolation of data and by operating with a temperature difference over the sample of less than 1 K

    We have compiled a catalogue of HII regions detected with the Murchison Widefield Array (MWA) between 72 and 231MHz. The multiple frequency bands provided by the MWA allow us identify the characteristic spectrum generated by the thermal Bremsstrahlung process in HII regions. We detect 306 HII regions between 260 < l < 340 and report on the positions, sizes, peak, integrated flux density, and spectral indices of these HII regions. By identifying the point at which HII regions transition from the optically thin to thick regime we derive the physical properties including the electron density, ionised gas mass and ionising photon flux, towards 61 HII regions. This catalogue of HII regions represents the most extensive and uniform low frequency survey of HII regions in the Galaxy to date.

    Corrosion patterns on samples taken on binder and rebars from two buildings, respectively, aged of 46 and 260 years old have been characterised by coupling different analytical methods at microscopic scale. Different corrosion patterns have been observed. The first one is constituted by the initial mill scale made of wustite, magnetite and hematite. The second one contains remains of this mill scale embedded in phases formed after aqueous corrosion: oxy-hydroxides as goethite or lepidocrocite containing marbling of ferri-hydrite, maghemite and magnetite. On the thicker and older layers, marbling were only constituted of magnetite and maghemite. It is proposed that the structural evolution of the pattern and their marbling is linked to wet/dry cycles and/or pH condition evolution during the corrosion processes. (authors)

    Within the unified ternary fission model (UTFM), the alpha accompanied ternary fission of even-even {sup 244-260}Cf isotopes has been studied by taking the interacting barrier as the sum of Coulomb and proximity potential. For the alpha accompanied ternary fission of the {sup 244}Cf isotope, the highest yield is obtained for the fragment combination {sup 108}Ru + {sup 4}He + {sup 132}Te, which contains the near doubly magic nucleus {sup 132}Te (N = 80, Z = 52). In the case of {sup 246}Cf and {sup 248}Cf isotopes, the highest yield is obtained for the fragment combinations with the near doubly magic nucleus {sup 134}Te (N = 82, Z = 52) as the heaviest fragment. The highest yield obtained for {sup 250}Cf, {sup 252}Cf, {sup 254}Cf, {sup 256}Cf, {sup 258}Cf and {sup 260}Cf isotopes is for the fragment combination with the doubly magic nucleus {sup 132}Sn (N = 82), Z = 50 as the heaviest fragment. We have included the effect of deformation and orientation of fragments and this has revealed that in addition to the closed shell effect, ground-state deformation also plays an important role in the calculation of the relative yield of favorable fragment combinations. The computed isotopic yields for the alpha accompanied ternary fission of the {sup 252}Cf isotope are found to be in agreement with the experimental data. The emission probability and kinetic energy of the long-range alpha particle is calculated for the various isotopes of Cf and are found to be in good agreement with the experimental data. (orig.)

    The megacity of Beijing has experienced frequent severe fine particle pollution during the last decade. Although the sources and formation mechanisms of aerosol particles have been extensively investigated on the basis of ground measurements, real-time characterization of aerosol particle composition and sources above the urban canopy in Beijing is rare. In this study, we conducted real-time measurements of non-refractory submicron aerosol (NR-PM1) composition at 260 m at the Beijing 325 m meteorological tower (BMT) from 10 October to 12 November 2014, by using an aerosol chemical speciation monitor (ACSM) along with synchronous measurements of size-resolved NR-PM1 composition near ground level using a high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS). The NR-PM1 composition above the urban canopy was dominated by organics (46 %), followed by nitrate (27 %) and sulfate (13 %). The high contribution of nitrate and high NO3- / SO42- mass ratios illustrates an important role of nitrate in particulate matter (PM) pollution during the study period. The organic aerosol (OA) was mainly composed of secondary OA (SOA), accounting for 61 % on an average. Different from that measured at the ground site, primary OA (POA) correlated moderately with SOA, likely suggesting a high contribution from regional transport above the urban canopy. The Asia-Pacific Economic Cooperation (APEC) summit with strict emission controls provides a unique opportunity to study the impacts of emission controls on aerosol chemistry. All aerosol species were shown to have significant decreases of 40-80 % during APEC from those measured before APEC, suggesting that emission controls over regional scales substantially reduced PM levels. However, the bulk aerosol composition was relatively similar before and during APEC as a result of synergetic controls of aerosol precursors. In addition to emission controls, the routine circulations of mountain-valley breezes were also found to play

    A simultaneous saccharification, fermentation, and recovery (SSFR) process was developed for the production of acetone-butanol-ethanol (AB or ABE), of which butanol is the main product, from corn stover employing Clostridium beijerinckii P260. Of the 86 g L(-1) corn stover provided, over 97% of the sugars were released during hydrolysis and these were fermented completely with an ABE productivity of 0.34 g L(-1)h(-1) and yield of 0.39. This productivity is higher than 0.31 g L(-1)h(-1) when using glucose as a substrate demonstrating that AB could be produced efficiently from lignocellulosic biomass. Acetic acid that was released from the biomass during pretreatment and hydrolysis was also used by the culture to produce AB. An average rate of generation of sugars during corn stover hydrolysis was 0.98 g L(-1)h(-1). In this system AB was recovered using vacuum, and as a result of this (simultaneous product recovery), 100% sugars were used by the culture.

  16. CONTINUED COOLING OF THE CRUST IN THE NEUTRON STAR LOW-MASS X-RAY BINARY KS 1731-260

    International Nuclear Information System (INIS)

    Some neutron star low-mass X-ray binaries have very long outbursts (lasting several years) which can generate a significant amount of heat in the neutron star crust. After the system has returned to quiescence, the crust then thermally relaxes. This provides a rare opportunity to study the thermal properties of neutron star crusts, putting constraints on the thermal conductivity and hence the structure and composition of the crust. KS 1731-260 is one of only four systems where this crustal cooling has been observed. Here, we present a new Chandra observation of this source approximately eight years after the end of the last outburst and four years since the last observation. We find that the source has continued to cool, with the cooling curve displaying a simple power-law decay. This suggests that the crust has not fully thermally relaxed yet and may continue to cool further. A simple power-law decay is in contrast to theoretical cooling models of the crust, which predict that the crust should now have cooled to the same temperature as the neutron star core.

    This study measured the flow rate, pH, and buffer capacity of saliva from children with Down syndrome aged 2-60 months. We compared 25 children with Down syndrome with 21 children without Down syndrome. The whole saliva was collected under slight suction and the pH and the buffer capacity were determined using a digital pHmeter. The buffer capacity was measured by titration with 0.01 N HCl. The Down syndrome group demonstrated higher buffer capacity than the control group in the pH ranges of 6.9-6.0, 5.9-5.0, and 4.9-4.0. The flow rate was low in the Down syndrome group. Boys from the Down syndrome group demonstrated higher buffer capacity in the pH ranges 6.9-6.0, 5.9-5.0, and 4.9-4.0 than controls, while girls from the Down syndrome group showed no difference compared with controls. Girls with Down syndrome demonstrated significant difference only in the range of pHi-pH 7.0. Conclusion. These data suggest that the Down syndrome persons present a better buffer capacity, supporting the results observed in several studies which found the low dental caries in persons with Down syndrome.

    In this article using Mehra (Aust. Math. Soc. 6:153, 1966) metric, we propose a model for the strange star in low-mass X-ray binary (LMXB) KS 1731-260 (Özel et al., Astrophys. J. 748:5, 2012) which describes interior space-time of the star. We study the strange star's interior and exterior physical properties. We calculate central density (ρ0), surface density (ρb), central pressure (p 0), surface redshift (Z s) and probable radius of the above mentioned strange star, which is very much consistent with the reported data. The special feature of this article is that the radius of the star is 12.31 km where pressure becomes zero and mass comes out as 2.09521 M_{⊙}, whereas maximum mass comes out as 2.09996 M _{⊙} with radius 12.53 km. Therefore, our model suggests that there may be a gaseous atmosphere over a range of 0.22 km outside of the stellar structure which justify the claim of Ho and Heinke (Nature 462:71, 2009).

    The Late Miocene and Pliocene are the key periods for understanding the origin and development of the present Asian monsoon circulations and ecologic environments. Here we present a pollen record from Chaona Red Clay section located in the central Loess Plateau in attempt to establish the histories of vegetation and associated climate changes between 8.10 and 2.60 Ma. Our results show that Gramineae-dominated woodland-grasslands developed in this region with Cedrus- and Pinus-characterized montane coniferous forests distributing in higher elevations from 8.10 to 6.73 Ma, probably suggesting a semi-humid climate in a warm-temperate zone. A subsequent expansion of Ulmus- dominated deciduous forests and a synchronous increase of Gramineae-dominated grassland reflect a warmer and more humid climate between 6.73 and 5.67 Ma. The vegetation changed to an Artemisia- and Gramineae-characterized steppe in lower elevations and to a coniferous forest in higher elevations from 5.67 to 3.71 Ma, implying probably a warm and semiarid climate in lowland and hill, and a colder and moister climate in mountain. During this period, a considerable warmer and more humid climate occurred between 4.61 and 4.07 Ma as indicated by pollen assemblages. The period between 3.71 and 2.58 Ma was characterized by the disappearance of Cedrus and Tsuga and also by an abrupt expansion of Cupressaceae, reflecting a drastic enhancement of monsoon-related climatic seasonality.

  6. Using a modified CINDER90 routine in MCNPX 2.6.0 for the prediction of helium production in minor actinide targets

    International Nuclear Information System (INIS)

    Highlights: ► Modification of the CINDER90 depletion code used by MCNPX 2.6.0. ► Testing using the Sodium-Cooled Heterogeneous Innovative Burner Reactor model. ► Verified using the ORIGEN-ARP module of SCALE6. ► Verified by depleting a single Sodium Fast Reactor assembly. ► Gas production rates are more accurate for heterogeneous MA target rods. - Abstract: Fast reactors containing heterogeneous minor actinide (MA) target rods are now being modeled. When studying transmutation in these rods, helium production from α-decay must be considered since it is produced in substantial quantities. This research utilized an innovative method to calculate gas production by modifying the CINDER90 depletion code used by MCNPX 2.6.0 to include helium production from α-decay. The modified CINDER90 code was verified using the ORIGEN-ARP module of SCALE6. It was tested using the Sodium-Cooled Heterogeneous Innovative Burner Reactor model created at the University of South Carolina. It is recommended that the modified version of the cinder.dat file be distributed in subsequent MCNPX 2.6.0 releases for use in fast reactor calculations using heterogeneous MA target rods since it includes helium production otherwise not available from the current version.

    Full Text Available Abstract Background The functional polymorphism -260 C>T in the LPS sensing TLR4 co-receptor CD14 gene enhances the transcriptional activity and results in a higher CD14 receptor density. Individuals carrying the T/T genotype also have significantly higher serum levels of soluble CD14. The T allele of this polymorphism has recently been linked to Chlamydia pneumoniae infection. We investigated the role of the CD14 -260 C>T polymorphism in the susceptibility to and severity (defined as subfertility and/or tubal pathology of C. trachomatis infection in Dutch Caucasian women. Methods The different CD14 -260 C>T genotypes were assessed by PCR-based RFLP analysis in three cohorts: 1 A cohort (n = 576 of women attending a STD clinic, 2 a cohort (n = 253 of women with subfertility, and 3 an ethnically matched control cohort (n = 170. The following variables were used in the analysis: In cohort 1 the CT-DNA status, CT IgG serology status, self-reported symptoms and in cohort 2, the CT IgG serology status and the tubal status at laparoscopy. Results In the control cohort the CC, CT and TT genotype distribution was: 28.2%, 48.2%, and 23.5% respectively. No differences were found in the overall prevalence of CD14 -260 genotypes (28.1%, 50.7%, and 21.2% in cohort 1 when compared to the control cohort. Also no differences were observed in women with or without CT-DNA, with or without serological CT responses, with or without symptoms, or in combinations of these three variables. In subfertile women with tubal pathology (cohort 2, n = 50 the genotype distribution was 28.0%, 48.0%, and 24.0% and in subfertile women without tubal pathology (n = 203, 27.6%, 49.3% and 23.2%. The genotype distribution was unchanged when CT IgG status was introduced in the analyses. Conclusion The CD14 -260 C>T genotype distributions were identical in all three cohorts, showing that this polymorphism is not involved in the susceptibility to or severity of sequelae of C. trachomatis

    Background: Obesity in pregnancy can contribute to epigenetic changes. Aim: To assess whether body mass index (BMI) in pregnancy is associated with changes in the methylation of the peroxisome proliferator-activated receptor γ (PPAR) promoter region (-359 to - 260) in maternal and neonatal leukocytes. Subjects and Methods: In this matched, cohort study 41 pregnant women were allocated into two groups: (a) Normal weight (n = 21) and (b) overweight (n = 20). DNA was extracted from maternal and neonatal leukocytes (4000-10,000 cells) in MagNA Pure (Roche) using MagNA Pure LC DNA Isolation Kit 1 (Roche, Germany). Treatment of DNA (2 μg) was performed with sodium bisulfite (EZ DNA Methylation-Direct™ Kit; Zymo Research). Real-time quantitative polymerase chain reaction (qPCR) was performed in a LightCycler 2.0 (Roche) using the SYBR® Advantage® qPCR Premix Kit (Clontech). The primers used for PPARγ coactivator (PPARG) M3 were 5’- aagacggtttggtcgatc-3’ (forward), and5’- cgaaaaaaaatccgaaatttaa-3’ (reverse) and those for PPARG unmethylated were: 5’-gggaagatggtttggttgatt-3’ (forward) and 5’- ttccaaaaaaaaatccaaaatttaa-3’ (reverse). Intergroup differences were calculated using the Mann-Whitney U-test, and intragroup differences, with the Wilcoxon test (IBM SPSS Statistics for Windows, Version 19.0. Armonk, NY: IBM Corp.). Results: Significant differences were found in BMI, pregestational weight, and postdelivery weight between groups but not in the methylation status of the PPARγ promoter region (-359 to - 260). Conclusion: The PPARγ promoter region (-359 to - 260) in peripheral leukocytes is unlikely to get an obesity-induced methylation in pregnancy. PMID:27144075

    NP260 was designed as a first-in-class selective antagonist of α4-subtype GABA{sub A} receptors that had promising efficacy in animal models of pain, epilepsy, psychosis, and anxiety. However, development of NP260 was complicated following a 28-day safety study in dogs in which pronounced elevations of serum aminotransferase levels were observed, although there was no accompanying histopathological indication of hepatocellular injury. To further investigate the liver effects of NP260, we assayed stored serum samples from the 28-day dog study for liver specific miRNA (miR-122) as well as enzymatic biomarkers glutamate dehydrogenase and sorbitol dehydrogenase, which indicate liver necrosis. Cytotoxicity assessments were conducted in hepatocytes derived from dog, rat, and human liver samples to address the species specificity of the liver response to NP260. All biomarkers, except ALT, returned toward baseline by Day 29 despite continued drug treatment, suggesting adaptation to the initial injury. In vitro analysis of the toxicity potential of NP260 to primary hepatocytes indicated a relative sensitivity of dog > human > rat, which may explain, in part, why the liver effects were not evident in the rodent safety studies. Taken together, the data indicate that a diagnostic biomarker approach, coupled with sensitive in vitro screening strategies, may facilitate interpretation of toxicity potential when an adaptive event masks the underlying toxicity. - Highlights: • NP260 caused ALT elevations in dogs without evidence of hepatocellular injury. • SDH, GLDH, and miRNA-122 elevations occurred, confirming hepatocellular necrosis. • NP260 toxicity is greater in dog and human hepatocytes than in rat hepatocytes. • Species sensitivity may explain why the rodent studies failed to indicate risk. • Diagnostic biomarkers and hepatocyte studies aid interpretation of hepatotoxicity.

  12. Deletion of the highly conserved N-glycan at Asn260 of HIV-1 gp120 affects folding and lysosomal degradation of gp120, and results in loss of viral infectivity.

    Directory of Open Access Journals (Sweden)

    Leen Mathys

    Full Text Available N-linked glycans covering the surface of the HIV-1 glycoprotein gp120 are of major importance for the correct folding of this glycoprotein. Of the, on average, 24 N-linked glycans present on gp120, the glycan at Asn260 was reported to be essential for the correct expression of gp120 and gp41 in the virus particle and deletion of the N260 glycan in gp120 heavily compromised virus infectivity. We show here that gp160 containing the N260Q mutation reaches the Golgi apparatus during biosynthesis. Using pulse-chase experiments with [35S] methionine/cysteine, we show that oxidative folding was slightly delayed in case of mutant N260Q gp160 and that CD4 binding was markedly compromised compared to wild-type gp160. In the search of compensatory mutations, we found a mutation in the V1/V2 loop of gp120 (S128N that could partially restore the infectivity of mutant N260Q gp120 virus. However, the mutation S128N did not enhance any of the above-mentioned processes so its underlying compensatory mechanism must be a conformational effect that does not affect CD4 binding per se. Finally, we show that mutant N260Q gp160 was cleaved to gp120 and gp41 to a much lower extent than wild-type gp160, and that it was subject of lysosomal degradation to a higher extent than wild-type gp160 showing a prominent role of this process in the breakdown of N260-glycan-deleted gp160, which could not be counteracted by the S128N mutation. Moreover, at least part of the wild-type or mutant gp160 that is normally targeted for lysosomal degradation reached a conformation that enabled CD4 binding.

    Results are reported on a room temperature static compression study of iron and the Fe(0.8)Ni(0.2) alloy to above 260 GPa, which provide direct pressure-volume measurements on geophysically important materials at the conditions close to those at the inner core boundary. The diffraction patterns obtained by XRD indicate that pure iron remains in the hcp structure to 304 GPa and that Fe(0.8)Ni(0.2) is stable to at least 255 GPa. The results of this study, in conjunction with work at higher temperatures, will make it possible to address directly the question of the composition of the inner core with a level of certainty that were previously applicable only to the mantle.

    Pressure, density, and temperature data for H{sub 2}O were obtained up to 260 GPa by using laser-driven shock compression technique. The shock compression technique combined with the diamond anvil cell was used to assess the equation of state models for the P-ρ-T conditions for both the principal Hugoniot and the off-Hugoniot states. The contrast between the models allowed for a clear assessment of the equation of state models. Our P-ρ-T data totally agree with those of the model based on quantum molecular dynamics calculations. These facts indicate that this model is adopted as the standard for modeling interior structures of Neptune, Uranus, and exoplanets in the liquid phase in the multi-Mbar range.

    The dehydration of the superprotonic conductor CsH{sub 2}PO{sub 4} has been carefully examined above 260 C under highly humidified conditions. A.C. impedance spectroscopy on heating revealed that the dehydration of CsH{sub 2}PO{sub 4} was accompanied by an increase in conductivity, whereas at temperatures below 260 C, CsH{sub 2}PO{sub 4} dehydrates to solid CsPO{sub 3} with decrease of conductivity. Based on a combination of thermogravimetric analyses, it was clarified that this phenomena was caused by the dehydration of CsH{sub 2}PO{sub 4} to form a liquid phase as follows: CsH{sub 2}PO{sub 4}(s) {yields} CsH{sub 2(1-x)}PO{sub 4} {sub -} {sub x}(l) + xH{sub 2}O(g). It was also determined that the liquid phase dehydrates to solid CsPO{sub 3} at higher temperatures and the stable region of CsH{sub 2}PO{sub 4}, dehydration liquid, and CsPO{sub 3} were established in the diagram of temperature and partial pressure of water. In addition, the electrical property of the dehydration liquid was measured by a.c. impedance spectroscopy as well as the d.c. polarization method. The liquid phase exhibited high ionic conductivity, 5({+-} 4) x 10{sup -} {sup 2} S cm{sup -} {sup 1}, at 283.5 C and p{sub H{sub 2}}{sub O} = 0.3 atm. (author)

  18. Work efficiency in the operations of juvenile thinning of mixed stands of pedunculate oak with hornbeam, ash and other hard broadleaves with the Stihl MS 260 chainsaw

    Full Text Available This paper presents the results of research of efficacy of the lightweight low power chainsaw Stihl MS 260 in the operations of juvenile thinning in preserved even-aged mixed stands of pedunculate oak with hornbeam, ash and other hard hardwoods. The investigations were carried out in the territory of FE “Sremska Mitrovica” in three sample plots of different ages. It is the first research of this kind based on the choice of optimal technological solution for the cleaning cuts of oak stands. Technology of work is based on cutting unwanted species at a certain height in order to favor pedunculate oak as the main species. In sample plot 1 the cutting through of undesirable species was carried out in one place and then third parties carried out their processing and transportation. In sample plots 2 and 3 workers cut the unwanted species in several places and stacked the timber on the ground so as not to interfere with the growth of pedunculate oak which does not tolerate shading. In this study, we applied time and work study. Group system of work was recorded. The group typically consisted of 4 workers and a foreman. Fuel consumption was recorded by the method of tank refuelling. The research results show that operating conditions have a significant impact on the effects of work with a chainsaw, as well as on the consumption of fuel and lubricants. The differences are mainly caused by different structures of cut timber.

  19. A hypothesis linking sub-optimal seawater pCO2 conditions for cnidarian-Symbiodinium symbioses with the exceedence of the interglacial threshold (>260 ppmv)

    Most scleractinian corals and many other cnidarians host intracellular photosynthetic dinoflagellate symbionts ("zooxanthellae"). The zooxanthellae contribute to host metabolism and skeletogenesis to such an extent that this symbiosis is well recognised for its contribution in creating the coral reef ecosystem. The stable functioning of cnidarian symbioses is however dependent upon the host's ability to maintain demographic control of its algal partner. In this review, I explain how the modern envelope of seawater conditions found within many coral reef ecosystems (characterised by elevated temperatures, rising pCO2, and enriched nutrient levels) are antagonistic toward the dominant host processes that restrict excessive symbiont proliferation. Moreover, I outline a new hypothesis and initial evidence base, which support the suggestion that the additional "excess" zooxanthellae fraction permitted by seawater pCO2 levels beyond 260 ppmv significantly increases the propensity for symbiosis breakdown ("bleaching") in response to temperature and irradiance extremes. The relevance of this biological threshold is discussed in terms of historical reef extinction events, glacial-interglacial climate cycles and the modern decline of coral reef ecosystems.

Indeed, a cortical accumulation of saturated very long chain fatty acids (VLCFAs: C22:0, C24:0, C26:0, substrates for peroxisomal β-oxidation, has been found in Alzheimer patients. This study was realized to investigate the effects of VLCFAs at the mitochondrial level since mitochondrial dysfunctions play crucial roles in neurodegeneration. On human neuronal SK-NB-E cells treated with C22:0, C24:0, or C26:0 (0.1–20 μM; 48 h, an inhibition of cell growth and mitochondrial dysfunctions were observed by cell counting with trypan blue, MTT assay, and measurement of mitochondrial transmembrane potential (Δψm with DiOC6(3. A stimulation of oxidative stress was observed with DHE and MitoSOX used to quantify superoxide anion production on whole cells and at the mitochondrial level, respectively. With C24:0 and C26:0, by Western blotting, lower levels of mitochondrial complexes III and IV were detected. After staining with MitoTracker and by transmission electron microscopy used to study mitochondrial topography, mass and morphology, major changes were detected in VLCFAs treated-cells: modification of the cytoplasmic distribution of mitochondria, presence of large mitochondria, enhancement of the mitochondrial mass. Thus, VLCFAs can be potential risk factors contributing to neurodegeneration by inducing neuronal damages via mitochondrial dysfunctions.

  8. Demonstration of GTS Duratek Process for Stabilizing Mercury Contaminated (<260 ppm) Mixed Wastes. Mixed Waste Focus Area. OST Reference No. 2409

    International Nuclear Information System (INIS)

    Mercury-contaminated wastes in many forms are present at various U. S. Department of Energy (DOE) sites. At least 26 different DOE sites have this type of mixed low-level waste in their storage facilities, totaling approximately 6,000 m3. Mercury contamination in the wastes at DOE sites presents a challenge because it exists in various forms, such as soil, sludges, and debris, as well as in different chemical species of mercury. Stabilization is of interest for radioactively contaminated mercury waste (<260 ppm Hg) because of its success with particular wastes, such as soils, and its promise of applicability to a broad range of wastes. However, stabilization methods must be proven to be adequate to meet treatment standards. They must also be proven feasible in terms of economics, operability, and safety. This report summarizes the findings from a stabilization technology demonstration conducted by GTS Duratek, Inc. Phase I of the study involved receipt and repackaging of the material, followed by preparations for waste tracking. Phase II examined the bench-scale performance of grouting at two different loadings of waste to grouted mass. Phase III demonstrated in-drum mixing and solidification using repackaged drums of sludge. Phase IV initially intended to ship final residues to Envirocare for disposal. The key results of the demonstration are as follows: (1) Solidification tests were performed at low and high waste loading, resulting in stabilization of mercury to meet the Universal Treatment Standard of 0.025 mg/L at the low loading and for two of the three runs at the high loading. The third high-loading run had a Toxicity Characteristic Leaching Procedure (TCLP) of 0.0314 mg/L. (2) Full-drum stabilization using the low loading formula was demonstrated. (3) Organic compound levels were discovered to be higher than originally reported, including the presence of some pesticides. Levels of some radionuclides were much higher than initially reported.

  9. Oxygen isotope and trace element evidence for three-stage petrogenesis of the youngest episode (260-79 ka) of Yellowstone rhyolitic volcanism

    We report the first high-precision δ18O analyses of glass, δ18O of minerals, and trace element concentrations in glass and minerals for the 260-79 ka Central Plateau Member (CPM) rhyolites of Yellowstone, a >350 km3 cumulative volume of lavas erupted inside of 630 ka Lava Creek Tuff (LCT) caldera. The glass analyses of these crystal-poor rhyolites provide direct characterization of the melt and its evolution through time. The δ18Oglass values are low and mostly homogeneous (4.5 ± 0.14 ‰) within and in between lavas that erupted in four different temporal episodes during 200 ka of CPM volcanism with a slight shift to lower δ18O in the youngest episode (Pitchstone Plateau). These values are lower than Yellowstone basalts (5.7-6 ‰), LCT (5.5 ‰), pre-, and extracaldera rhyolites (~7-8 ‰), but higher than the earliest 550-450 ka post-LCT rhyolites (1-2 ‰). The glass δ18O value is coupled with new clinopyroxene analyses and previously reported zircon analyses to calculate oxygen isotope equilibration temperatures. Clinopyroxene records >900 °C near-liquidus temperatures, while zircon records temperatures Yellowstone rhyolites: (1) repeated batch melting events at the base of a homogenized low-δ18O intracaldera fill resulting in liquidus rhyolite melt and a refractory residue that sequesters feldspar-compatible elements over time. This melting may be triggered by conductive "hot plate" heating by basaltic magma intruding beneath the Yellowstone caldera resulting in contact rhyolitic melt that crystallizes early clinopyroxene and/or sanidine at high temperature. (2) Heterogeneity within individual samples and across flows reflects crystallization of these melts during preeruptive storage of magma at at lower, zircon-saturated temperatures. Compatible behavior and variations of most trace elements within individual lava flows are the result of sanidine, quartz, Fe-Ti oxide, zircon, and chevkinite crystallization at this stage. (3) Internal mixing

    This work is focussed on the investigation of deformed nuclei. The asymmetric fusion-fission of light heavy-ions (A {<=}60) with a high excitation energy (T {approx} 4 MeV) had lead to a large deformation of the compound nucleus at the scission point. The angular correlations between light particles (LP) and their emitting fragments has been used to probe the deformation of nucleus. Exclusive measurements were performed for the {sup 35}Cl (260 MeV) + {sup 24}Mg system leading to the {sup 59}Cu compound nucleus (CN). The comparison between the energy spectra of LP`s and a statistical calculation carried out by a Monte-Carlo code CASCADE has suggested a deformation of 1.3 (for an oblate shape) of the CN within the frame work of fusion-evaporation process. The source velocity spectrum of {alpha} particles and angular correlations of LP`s have showed that pre-scission and pre-equilibrium emissions are negligible in the present reaction. Finally the confrontation of the data with the statistical code GEMINI has pointed out the sequential emission character of the LP`s from the fission fragments. (author). 175 refs.

    Objective To investigate the HIV and syphilis infection in MSM in Jiujiang City, to explore the model of behavior intervention among MSM, and to provide a scientific basis for making intervention measures. Methods Respondent driven sampling (RDS) was employed, and cross sectional anonymous questionnaire survey was conducted for 260 MSM in Jiujiang. Serum syphilis and HIV detection were given to volunteers selected from the anonymous questionnaires survey in male homosexuality population of Jiujiang. Results In the past 6 months, 93.46% had male sexual partners, and only 21.40% of them used condom persistently. Besides, 17.69% had sex with female, but only 8.70% of them used condom with their female sexual partners persistently. The subjects had certain degree knowledge on AIDS, but the rate of STD diagnosis and treat was very low. Only 40 MSM intentionally checked the anti - HIV in the past year. The infection rate of syphilis and HIV was 3.08 % and 1.92 %, respective. Conclusions Self - perceived risk of HIV infection was low among MSM, and unsafe sex was frequent. With the serious AIDS/STD epidemic, the wrong way for medical care might also strengthen the prevalence of AIDS/STD. It is urgent to take targeted intervention towards MSM.%目的 调查九江市男男性行为者(MSM)梅毒、HIV感染及知识行为现状,了解其流行特征,探讨对该人群实施行为干预的模式,为制定干预措施提供科学依据.方法 采用同伴推动抽样(RDS)方法,对九江市260名MSM人群开展横断面匿名问卷调查,并对自愿参加检测的人员采集血样进行梅毒、艾滋病病毒(HIV)检测.结果 在最近六个月内,93.46%的MSM有男性性伴,只有21.40%的MSM每次都使用了安全套;而17.69%曾与女性发生过性行为,只有8.70%每次都使用了安全套.被调查者艾滋病知识平均知晓率为91.92%,而性病艾滋病检查及治疗接受率很低.近一年内只有40人(15.4%)曾主动检测

    Temperature-dependence surface relief during cubic↔tetragonal martensitic transformation (MT) in Mn69.4Fe26.0Cu4.6 antiferromegnetic shape memory alloy was studied by means of in-situ atomic force microscopy. The surface morphology memory effect was found and the crystallography reversibility of the transformation and its shearing characters were directly verified. Twin shearing is suggested as the main mechanism of formation of tent-type surface relief. The surface relief angle (θα|θβ)<0.5° was firstly measured and might be the smallest compared with that in other shape memory alloys. A Landau model was proposed to consider the shearing strain related with surface relief of MT varying with the coupling effect between second-order antiferromagnetic transition and first-order MT. According to this model, the Mn69.4Fe26.0Cu4.6 alloy belongs to the weak coupling system and this kind of weak coupling effect makes the main contribution to the small relief angle.

    The absorption spectrum of the 16O12C18O and 12C18O2 carbon dioxide isotopologues has been recorded in the 11,260- 11,430 cm-1 spectral range using Bruker IFS 125 HR Fourier transform spectrometer with resolution 0.05 cm-1 at temperature 297 K and path length 24 m. The 18O enriched sample of carbon dioxide at total pressure 96.5 mbar was used for these purposes. The spectrometer used LED emitter as a light source. This gave possibility to reach the minimal detectable absorption coefficient αmin~1.4×10-7 cm-1 using 23,328 scans. In the recorded spectrum we have assigned the 00051-00001 band for both 16O12C18O and 12C18O2 isotopologues using the predictions performed within the framework of the method of effective operators. The line positions and intensities of the observed bands are found. The comparison of the observed and predicted line positions and intensities is performed confirming good accuracy of the predictions. The spectroscopic parameters for the observed bands are determined.

    2000-07-01

    As has been shown in the stretch forming and deep drawing tests, the newly developed HSZ steels are particularly suitable for the production of large exposed car body parts, such as roofs, doors and hoods. They are rather unfavourable for applications required higher drawing depths. Owing to its excellent strain hardening behaviour and a relatively high yield strength, the HSZ steel grades exhibits a good dent resistance. For weight reduction purposes, it is possible to replace soft aluminium-killed steels or IF steels by HSZ steels with reduced sheet thicknesses. If corrosion protection is required, HSZ grades are also available electrogalvanized. (orig.)

  1. Optical Extinction of Sapphire Shock Loaded to 250-260 GPa

    Energy Technology Data Exchange (ETDEWEB)

    Hare, D E; Webb, D J; Lee, S H; Holmes, N

    2001-08-21

    Sapphire, a common optical window material used in shock-compression studies, displays significant shock-induced optical emission and extinction. It is desirable to quantify such non-ideal window behavior to enhance the usefulness of sapphire in optical studies of opaque shock-compressed samples, such as metals. At the highest stresses we can achieve with a two-stage gas gun it is technically very difficult to study the optical properties of sapphire without the aid of some opaque backing material, hence one is invariably compelled to deconvolve the optical effects of the opaque surface and the sapphire. In an effort to optimize this deconvolution process, we have constructed sapphire/thin-film/sapphire samples using two basic types of thin films: one optimized to emit copious optical radiation (the hot-film sample), the other designed to yield minimal emission (the cold-film sample). This sample geometry makes it easy to maintain the same steady shock-stress in the sapphire window (255 GPa in our case) while varying the window/film interface temperature. A six-channel time-resolved optical pyrometer is used to measure the emission from the sample assemblies. Two different sapphire crystal orientations were evaluated. We also comment on finite thermal conductivity effects of the thin-film geometry on the interpretation of our data.

  2. Reflections on solar collectors at elevated temperatures /260-1000 C/

    Science.gov (United States)

    Authier, B.

    1982-06-01

    Analytical models are developed for optical efficiencies and requirements of concentrating solar collectors, taking into account factors which affect the potentials for mass production. Reflective polyester films and a process to form large spherical mirrors from glass sheets have been crucial factors for lowering production costs. Microprocessors permit the nearly fully automated operation of parabolic dish point-focus and heliostat-central tower solar power plants, leaving only monitoring and maintenance for personnel. The use of GaAs-AsAl solar cells at the point focus of large spherical concentrators in the PERICLES project has yielded 22 percent energy conversion efficiences, although problems of cooling the cells have yet to be solved. Applications of the PERICLES concept for Indian village power supplies at 10 kWe/unit, while simultaneously supplying a drain hole at the center as a rainwater collection device, is described.

  9. Decision 2010-021 : TransAlta Wind Ardenville wind plant and substation : application no. 1604970, proceeding ID 260

    International Nuclear Information System (INIS)

    TransAlta Wind, a wholly owned subsidiary of TransAlta Corporation, filed an application in April 2009 to construct and operate the Ardenville wind farm and substation in Alberta. The wind farm consists of 23 wind turbines, each rated at 3 MW, for a total installed capacity of 69 MW. The wind farm would be connected to the Alberta Interconnected Electric System at the substation. TransAlta anticipates that a new 138-kV transmission line will be required and has contacted the transmission facilities for the future applications. The Alberta Utilities Commission issued a notice to all interested parties and landholders within 2 km of the proposed wind farm. Two residents raised concerns regarding the use of fossil fuels and alternative fuels, ecological impacts and aesthetic impacts of wind farms and land values. Upon review of information, the Commission was satisfied that approval of the application was in the public interest and that the wind farm complies with all regulatory requirements, including sound levels. Pursuant to sections 11, 14 and 15 of the Hydro and Electric Energy Act, the Commission approved the application and granted approval to TransAlta Wind to construct and operate the Ardenville wind power plant and substation.

    2015-06-15

    Purpose: To identify the effective quantitative image features (radiomics features) for prediction of response, survival, recurrence and metastasis of hepatocellular carcinoma (HCC) in radiotherapy. Methods: Multiphase contrast enhanced liver CT images were acquired in 16 patients with HCC on pre and post radiation therapy (RT). In this study, arterial phase CT images were selected to analyze the effectiveness of image features for the prediction of treatment outcome of HCC to RT. Response evaluated by RECIST criteria, survival, local recurrence (LR), distant metastasis (DM) and liver metastasis (LM) were examined. A radiation oncologist manually delineated the tumor and normal liver on pre and post CT scans, respectively. Quantitative image features were extracted to characterize the intensity distribution (n=8), spatial patterns (texture, n=36), and shape (n=16) of the tumor and liver, respectively. Moreover, differences between pre and post image features were calculated (n=120). A total of 360 features were extracted and then analyzed by unpaired student’s t-test to rank the effectiveness of features for the prediction of response. Results: The five most effective features were selected for prediction of each outcome. Significant predictors for tumor response and survival are changes in tumor shape (Second Major Axes Length, p= 0.002; Eccentricity, p=0.0002), for LR, liver texture (Standard Deviation (SD) of High Grey Level Run Emphasis and SD of Entropy, both p=0.005) on pre and post CT images, for DM, tumor texture (SD of Entropy, p=0.01) on pre CT image and for LM, liver (Mean of Cluster Shade, p=0.004) and tumor texture (SD of Entropy, p=0.006) on pre CT image. Intensity distribution features were not significant (p>0.09). Conclusion: Quantitative CT image features were found to be potential predictors of the five endpoints of HCC in RT.

    ECX21941 represents a very large family (over 600 members) of novel, ocean metagenome-specific proteins identified by clustering of the dataset from the Global Ocean Sampling expedition. The crystal structure of ECX21941 reveals unexpected similarity to Sm/LSm proteins, which are important RNA-binding proteins, despite no detectable sequence similarity. The ECX21941 protein assembles as a homopentamer in solution and in the crystal structure when expressed in Escherichia coli and represents the first pentameric structure for this Sm/LSm family of proteins, although the actual oligomeric form in vivo is currently not known. The genomic neighborhood analysis of ECX21941 and its homologs combined with sequence similarity searches suggest a cyanophage origin for this protein. The specific functions of members of this family are unknown, but our structure analysis of ECX21941 indicates nucleic acid-binding capabilities and suggests a role in RNA and/or DNA processing.

  14. A Two-Color Fourier Transform Mm-Wave Spectrometer for Gas Analysis Operating from 260-295 GHZ

    Science.gov (United States)

    Steber, Amanda L.; Harris, Brent J.; Lehmann, Kevin K.; Pate, Brooks H.

    2013-06-01

    We have designed a two-color mm-wave spectrometer for Fourier transform mm-wave spectroscopy that uses consumer level components for the tunable synthesizers, digital control of the pulse modulators, and digitization of the coherent free induction decay (FID). The excitation pulses are generated using an x24 active multiplier chain (AMC) that produces a peak power of 30 mW. The microwave input to the AMC is generated in a frequency up conversion circuit that accepts a microwave input frequency from about 2-4 GHz. This circuit also generates the input to the mm-wave subhamonic mixer that creates the local oscillator from a separate 2-4 GHz microwave input. Excitation pulses at two independently tunable frequencies are generated using a dual-channel source based on a low-cost, wideband synthesizer integrated circuit (Valon Technology Model 5008). The outputs of the synthesizer are pulse modulated using a PIN diode switch that is driven using the arbitrary waveform generator (AWG) output of a USB-controlled high-speed digitizer / arbitrary waveform generator combination unit (Tie Pie HS-5 530 XM). The two pulses are combined using a Wilkinson power divider before input to the up conversion circuit. The FID frequency is down converted in a two-stage mixing process to 65 MHz. The two LO frequencies used in the receiver are provided by a second Valon 5008. The FID is digitized at 200 MSamples/s using the 12-bit Tie Pie digitizer. The digital oscilloscope (and its AWG channel) and the two synthesizers use a 10 MHz reference signal from a Rubidium clock to permit time-domain signal averaging. A key feature of the digital oscilloscope is its deep memory of 32 Mpts (complemented by the 64 Mpt memory in the 240 MS/s AWG). This makes it possible to perform several one- and two-color coherent measurements, including pulse echoes and double-resonance spectroscopy, in a single "readout" experiment to speed the analysis of mm-wave rotational spectra. The spectrometer sensitivity and frequency accuracy are illustrated by high-speed measurements of OCS rotational transitions for low-abundance isotopes. Examples of pulse echo measurements to determine the collisional relaxation rate and two-color double-resonance measurements to confirm the presence of a molecular species will be illustrated using OCS as the room-temperature gas sample.

    Full Text Available Abstract Background Randomized controlled trials (RCTs which are of poor quality tend to exaggerate the effect estimate and lead to wrong or misleading conclusions. The aim of this study is to assess the quality of randomization methods, allocation concealment and blinding within traditional Chinese medicine (TCM RCTs, discuss issues identified for current TCM RCTs, and provide suggestions for quality improvement. Methods We searched Chinese Biomedical Database (CBM, 1978 to July 31, 2009 and the Cochrane Library (Issue 2, 2009 to collect TCM systematic reviews and meta-analyses according to inclusion/exclusion criteria, from which RCTs could be identified. The quality assessment involved whether the randomization methods, allocation concealment and blinding were adequate or not based the study reported. Stratified analyses were conducted of different types of diseases published in different journals (both Chinese and foreign using different interventions. SPSS 15.0 software was used for statistic analyses. Results A total of 3159 RCTs were included, of which 2580 were published in Chinese journals and 579 in foreign journals. There were 381 (12% RCTs which used adequate randomization methods; 207 (7% RCTs which used adequate allocation concealment and 601 (19% which used adequate blinding; there were 130 (4% RCTs which both used adequate randomization methods and allocation concealment; and there were only 100 (3% RCTs which used adequate randomization methods, allocation concealment, as well as blinding. In the RCTs published in foreign journals, the adequate randomization methods, allocation concealment and blinding accounted for a relatively large proportion (25%, 26%, and 60%, respectively and increased with years, while in the RCTs published in Chinese journals, only the adequate randomization methods improved over time. The quality of non-drug intervention (chiefly acupuncture RCTs was higher than that of drug intervention RCTs. In drug intervention, the quality of listed drugs is higher than the others. The quality of all included RCTs of all types of diseases was generally poor and no studies that were large in size and of high quality were found. Conclusion The quality of the current TCM RCTs as judged by their publications is generally poor, especially those published in Chinese journals. In future, researchers of TCM RCTs should attach more importance to experimental design and methodological quality, receive relevant training, and improve reporting quality using the Consolidated Standards of Reporting Trials (CONSORT statement, so as to improve the quality of TCM clinical research and ensure truth and reliability of conclusions.

    The orbital and interior climatic cycles can be found both in the Bengal Deep Sea Fan and Ninetyeast Ridge, North Indian Ocean. The periodicity of the Quaternary glacio-eustacy by 100 ka gave a strong impact on the sedimentation in the fan area and the monsoon signals controlled by the obliquity and precession were easily picked up. This paper discusses the possible correlation between the environmental elements on the basis of the ETP phase wheels. A rapid change with short-periods develops during the past 60 ka in the region under study as well. The variability of paleoproductivity has a nonlinear response to the Indian summer monsoon. As contrasted to the Northwest Indian Ocean, here an abundance of Globigerina bulloides, a proxy to indicate upwelling current, does not imply so much a promotion of the summer monsoon as its decrease. The record from the ridge area shows in a longer-scale a climatic evolutionary feature corresponding to that of the fan area. A special and great event arising at around 1

    Full Text Available Se estudiaron 110 niños entre los 2 y los 60 meses de edad, con diagnóstico de neumonía adquirida en la comunidad, en el Hospital Francisco Valderrama del municipio de Turbo, Antioquia, pertenecientes al programa Vida Infantil de la Universidad de Antioquia. Los criterios de inclusión fueron la taquipnea y el tiraje de acuerdo con las normas de la OMS para el diagnóstico de la infección respiratoria baja en lactantes y preescolares en países en vías de desarrollo. Los pacientes se estudiaron microbiológicamente mediante hemocultivos, prueba de látex para antígenos bacterianos en la orina, prueba de Elisa para Micoplasma pneumoniae y panel respiratorio para los virus que causan más frecuentemente dicha enfermedad. Se hicieron además hemoleucogramas y radiografías pulmonares. Todas las muestras se tomaron bajo criterios protocolizados y se trasladaron por vía aérea a la ciudad de Medellín bajo normas estrictas de conservación, para ser procesadas en el Laboratorio de Investigaciones en Infectología Pediátrica de la Universidad de Antioquia. Los exámenes más adecuados para la comprobación del diagnóstico fueron las radiografías de tórax con 77%; los hemocultivos con una positividad de 11.1%, el panel respiratorio con 3.7%, la prueba de látex para los antígenos bacterianos con 7.4% y la prueba de ELISA con 0.9%. Los hemoleucogramas tuvieron un amplio margen de variabilidad. No se encontró relación estadística entre las variables epidemiológicas estudiadas y la gravedad de la infección. El estudio confirma la escasa sensibilidad de los exámenes paraclínicos y reafirma la importancia del diagnóstico clínico temprano como base para iniciar la terapia. One hundred and ten children aged between 2 and 60 months with the diagnosis of communityacquired pneumoniae, were studied at Francisco Valderrama Hospital in the city of Turbo, Colombia; they belonged to the University of Antioquia Child Life program. Admission criteria were tachypnea and retraction according to the WHO guidelines for lower respiratory tract infection diagnosis in infants and preschool children in developing countries. Patients were studied microbiologically by means of blood cultures, urine latex aggutination test for bacterial antigens, ELISA test for Mycoplasma pneumoniae, and a panel for respiratory viruses that frequently cause this disease. Blood specimens and pulmonary radiographies were also taken under protocolized criteria and the former were transported by plane to Medellín under strict measures of preservation, in order to be processed at the Pediatric Investigation and Infectology Laboratory of the University of Antioquia. Radiographies were positive in 77% of cases, blood cultures in 11.1%, latex agglutination for bacterial antigens in 7.4%, respiratory viruses panel in 3.7%, and ELISA test in 0.9%. Hemoleucograms had a wide range of variability. Relationships between epidemiological variables and the severity of the infection were not found. The study confirms the scarce positivity of paraclinical tests and reaffirms the importance of early clinical diagnosis as the basis for starting therapy.

  9. Systematic study of Bh isotopes in a relativistic mean field formalism

    International Nuclear Information System (INIS)

    The binding energy, charge radius, and quadrupole deformation parameter for the isotopic chain of the superheavy element bohrium (107Bh), from proton to neutron drip line, are calculated by using an axially deformed relativistic mean field model. The potential energy surfaces for some of the selected nuclei are plotted and the various possible shapes are investigated. The rms radii, density distributions, and two-neutron separation energies are also evaluated and the single-particle energies for some illustrative cases are analyzed to see the magic structures. Furthermore, the α-decay rates are calculated and compared with the available experimental data for the recently observed new isotopes 266,267Bh

    International Nuclear Information System (INIS)

    Although originally planned for fundamental research in nuclear physics, the particle beams of pions, muons, protons and neutrons are now used in a large variety of disciplines in both natural science and medicine. The beams at PSI have the world's highest intensities and therefore allow certain experiments to be performed, which would not be possible elsewhere. The highlight of research this year was the first-ever determination of the chemical properties of the superheavy element 107 Bohrium. This was undertaken, by an international team led by H. Gaeggeler of PSI's Laboratory for Radiochemistry. Bohrium was produced by bombarding a Berkelium target with Neon ions from the Injector I cyclotron and six atoms were detected after having passed through an online gas chromatography device. At the Laboratory for Particle Physics the focus has shifted from nuclear physics to elementary particle physics with about a fifty-fifty split between investigations of rare processes or particle decays using the high intensity muon, pion and recently also polarized neutron beams of PSI, and research at the highest energy frontier at CERN (Geneva) and DESY (Hamburg). Important space instrumentation has been contributed by the Laboratory for Astrophysics to the European Space Agency and NASA satellite programmes. The Laboratory for Micro and Nanotechnology continued to focus on research into molecular nanotechnology and SiGeC nanostructures, the latter with the aim of producing silicon based optoelectronics. Progress in 1999 in these topical areas is described in this report. A list of scientific publications in 1999 is also provided

    It is pointed out that in-process tests to verify quality and detect discrepant propellant which could compromise motor performance are essential elements of the solid composite propellant manufacturing process. The successful performance of the 260SL-1 and 260SL-2 motors aptly verified the controls used for manufacturing the propellant. The present investigation is concerned with the selected control parameters, and their relationships to composition and final propellant properties. Control performance is evaluated by comparison with processing data experienced in the manufacture of the propellant for the 260SL-1 motor. It is found that the in-process quality verification controls utilized in the propellant manufacturing process for the 260-in. diameter motor contributed significantly to the confidence of successful and predictable motor performance.

  1. Properties of Group Five and Group Seven transactinium elements

    Energy Technology Data Exchange (ETDEWEB)

    2001-05-01

    The detection and positive identification of the short-lived, low cross section isotopes used in the chemical studies of the heaviest elements are usually accomplished by measuring their alpha-decay, thus the nuclear properties of the heaviest elements must be examined simultaneously with their chemical properties. The isotopes 224 Pa and 266,267 Bh have been studied extensively as an integral part of the investigation of the heaviest members of the groups five and seven of the periodic table. The half-life of 224 Pa was determined to be 855 plus/minus19 ms by measuring its alpha-decay using our rotating wheel, solid state detector system at the Lawrence Berkeley National Laboratory 88-Inch Cyclotron. Protactinium was produced by bombardment of a bismuth target. New neutron rich isotopes, 267 Bh and 266 Bh, were produced in bombardments of a 249 Bk target and their decay was observed using the rotating wheel system. The 266 Bh that was produced decays with a half-life of approximately 1 s by emission of alpha particles with an average energy of 9.25 plus/minus 0.03 MeV. 267 Bh was observed to decay with a 17 s half-life by emission of alpha-particles with an average energy of 8.83 plus/minus 0.03 MeV. The chemical behavior of hafnium, Ha (element 105) was investigated using the fast on-line continuous liquid extraction and detection system SISAK-LISSY. Hafnium was not observed in this experiment following transport and extraction. Protactinium was used as on-line test of the apparatus to determine the experimental efficiency of the entire system. Unfortunately, the amount of protactinium observed after the extraction, compared to the amount produced, was extremely small, only 2.5%. The extraction of the protactinium isotope indicated the efficiency of the apparatus was too low to observe the extraction of hafnium. The chemical behavior of oxychloride compounds of bohrium was investigated by isothermal gas adsorption chromatography in a quartz column at 180, 150

  2. An experimental paradigm opening the world of superheavy elements

    The history of the discovery of the six elements Z = 107 ∓ 112, bohrium, hassium, meitnerium, darmstadtium, roentgenium, and copernicium goes back to the early 1960s. An experimental method to separate and identify rare nuclear reaction products, the recoil separation, was developed and optimised for beams of fission products at European research reactors. Chemical elements beyond the then first transactinides ( Z = 104), which owe their stability to the internal structure of atomic nuclei, were predicted theoretically. A big brother of the shell-stabilised nucleus 208Pb, a spherical magic nucleus at Z = 114∓126 and N = 184, might reach lifetimes long enough to be detected. In the seventies, hunting superheavy elements (SHE) was on the agenda of nuclear chemistry. Could the Periodic Table of Elements be extended to Z = 120, and is the order of electrons in the atom still following the laws established for lighter elements? In Germany, the heavy ion accelerator (UNILAC) was built by Christoph Schmelzer and his team at GSI, Darmstadt. SHE and UNILAC met the recoil separators in 1968, and SHIP (Separator for Heavy Ion reaction Products) was ready together with the first UNILAC-beams in 1976. Recoil separation is orders of magnitude more sensitive, selective, and faster than earlier methods used to synthesise elements up to seaborgium, Z = 106. The experimental paradigm we introduced opened the world of SHEs. At SHIP we discovered and investigated the elements Z = 107∓112 in the years 1980-2000. Our laboratory was the world champion during this time. Today our experimental method is used worldwide in the search for SHEs, but the leadership went to the Russian laboratory JINR in Dubna, which extended the Periodic Table by 6 more elements to Z = 118, the candidate for the next rare gas.

  3. Synthesis of the heaviest nuclei in cold fusion reactions

    Science.gov (United States)

    Münzenberg, G.; Morita, K.

    2015-12-01

    Cold fusion of heavy ions paved the way to superheavy elements. It was proposed by Yu.Ts. Oganessian more than forty years ago in 1974 [1,2]. First experiments were carried out at JINR Dubna, starting with the reaction 40Ar + 208Pb → 248Fm* where several hundreds to thousand atoms were produced on one day. The large production rate indicating an enhancement of the fusion cross section, especially for the evaporation of two or three neutrons, proved the concept of cold-fusion with the use of the doubly magic nucleus 208Pb as a target. The Dubna experiments were extended to the transactinide region beyond rutherfordium. The breakthrough came with the separation in-flight. Two different approaches were used: kinematic separation with the velocity filter SHIP [3] at GSI Darmstadt, and with the gasfilled separator GARIS [4,5] at RIKEN. With SHIP the concept of cold fusion of massive nuclear systems was convincingly confirmed by the observation of the one-neutron evaporation channel in the production of 247Rf in an irradiation of 208Pb with 50Ti [6] in 1981 which opened the way to the transactinide region. At SHIP the elements bohrium (107) to copernicium (112) were discovered [7]. A new closed shell region around hassium was found. The RIKEN experiments started in 2002. They confirmed the GSI results and in addition improved the data on structure and production of elements hassium to copernicium significantly. The heaviest element ever created in a cold fusion reaction, Z = 113, was observed at GARIS [8,9].

  4. Thermally stimulated processes involving defects in γ- and x-irradiated spinel (MgAl2O4)

    International Nuclear Information System (INIS)

    Thermally stimulated conductivity (TSC) and thermally stimulated luminescence (TSL) of spinel single crystals exposed to ionizing radiation have been studied. TSC exhibits peaks at 70, 125, and 340 0C whereas TSL peaks occur at 70 and 260 0C. The 70 0C peak has an activation energy of 0.95 eV and is due to electron release; it has two main spectral components at 260 nm (4.8 eV) and 310 nm (4.0 eV) due to electron capture at trapped holes. The 260 0C TSL peak is broad but singly activated (1.5 eV activation) and is dominated by 710 nm (1.75 eV) and 520 nm (2.39 eV) emission due to hole capture at Cr2+ and V2+, respectively. The broad 3400 TSC peak appears to contain a substantial contribution due to electron release in the 240--310 0C range which makes only a small contribution (260 and 310-nm light) to the TSL peak in this region. Dose dependence and room-temperature decay indicate that initially a substantial portion of the 260-nm afterglow is due to tunneling recombination

  5. Evaluation of Estrogenic Activity and Measurement of EDCs in Wastewater Treatment Plants

    Correlations between estrogenic activity and DOC/UV260 ratio in wastewater treatment processes were investigated to propose a simple, reliable and comprehensive indicator for the presence of estrogenic substances. Contrary to this,when short-term bioassays such as the E-SCREEN, receptor binding and reporter gene expression assays are used for detecting estrogenic activity in the wastewater sample, they require a long time, at least a few days. The major factors contributing to the estrogenic activity were found to be 17β-estradiol (E2) and estrone (E1). A good relationship between the DOC/UV260 ratio and the concentration of estrogens (E1 and E2) in the effluent of the activated sludge process was found: the E2 concentration increased as the DOC/UV260 ratio increased while the E1 concentration decreased. The relative estrogenic activity and DOC/UV260 ratio showed a good correlation (R2 = 0.84) for all sewage samples except the ozonized samples in the sewage treatment plants. This study shows that the estrogenic compounds are hard to be mineralized by the conventional biological processes. Advanced oxidation processes are required to further remove estrogenic substances in the secondary effluent. By analysis of DOC and UV260, the estrogenic activity in the wastewater can be rapidly estimated.

  8. Incorporation of Cu2O nanocrystals into TiO2 photonic crystal for enhanced UV–visible light driven photocatalysis

    International Nuclear Information System (INIS)

    Highlights: • The Cu2O NCs/TiO2 PC composite was synthesized and exhibited high photocatalysis. • The improved light harvesting and increased quantum yield was achieved. • The hydroxyl radical was the primary oxidant in Cu2O NCs/TiO2 PC photocatalysis. - Abstract: A 3D UV–visible light responsive photocatalyst was fabricated by infiltrating Cu2O nanocrystals (NCs) into TiO2 photonic crystal (PC). Morphology characterization presented that Cu2O NCs with average diameter around 10 nm were dispersed uniformly into TiO2 PC. The transmittance spectra showed that Cu2O NCs/TiO2 260, prepared by integrating Cu2O NCs with TiO2 260 which was fabricated from 260 nm polystyrene spheres, exhibited the highest light harvesting. The photoluminescence spectra confirmed the electron/hole pairs recombination of Cu2O NCs/TiO2 260 was efficiently inhibited due to the unique heterojunction structure between TiO2 and Cu2O. In the photocatalytic degradation of Rhodamine B and Bisphenol A under UV–visible light (320 nm < λ < 780 nm) irradiation, the kinetic constant using Cu2O NCs/TiO2 260 was 3.99 and 8.37-fold larger than that using TiO2 nanoparticle (NP), respectively. The enhanced photocatalysis benefited from the increased light harvesting owing to the excitation of both TiO2 and Cu2O NCs whose optical absorption was intensified by the photonic effect of TiO2 260 and the high quantum efficiency due to the Cu2O/TiO2 heterojunction. The hydroxyl radical, generated from the protonation of superoxide radical which was derived from the reduction of oxygen by photogenerated electrons, was the main oxidant responsible for pollutant degradation

    AIM To gather data on the antiviral efficacy and safety of second generation direct acting antiviral (DAA) treatment with respect to sustained virological response (SVR) 12 wk after conclusion of treatment, and to determine predictors of SVR12 in this setting. METHODS Two hundred and sixty patients treated with SOF combination partners PR (n = 51), R (n = 10), SMV (n = 30), DCV (n = 81), LDV (n = 73), or 3D (n = 15). 144/260 were pre-treated, 89/260 had liver cirrhosis, 56/260 had portal hypertension with platelets < 100/nL, 25/260 had a MELD score ≥ 10 and 17/260 were post-liver transplantation patients. 194/260 had HCV GT1, 44/260 HCV GT3. RESULTS Two hundred and forty/256 (93.7%) patients achieved SVR12 (mITT); 4/260 were lost to follow-up. SVR12 rates for subgroups were: 92% for SOF/DCV, 93% for each SOF/SMV, SOF/PR, 94% for SOF/LDV, 100% for 3D, 94% for pretreated, 87% for liver cirrhosis, 82% for patients with platelets < 100/nL, 88% post-liver transplantation, 95% for GT1a, 93% for GT1b, 90% for GT3, 100% for GT2, 4, and 6. 12 patients suffered from relapse, 6 prematurely discontinued treatment, of which 4 died. Negative predictors of SVR12 were a platelet count < 100/nL, MELD score ≥ 10 (P < 0.0001), liver cirrhosis (P = 0.005) at baseline. In Interferon-free treatment GT3 had significantly lower SVR rates than GT1 (P = 0.016). Side effects were mild. CONCLUSION Excellent SVR12 rates and the favorable side-effect profile of DAA-combination therapy can be well translated into “real-world”. Patients with advanced liver disease, signs of portal hypertension, especially with platelets < 100/nL and patients with GT3 are in special need for further research efforts to overcome comparatively higher rates of virological failure.

    Paclitaxel is widely used in the treatment of patients with metastatic breast cancer (MBC). Formulations of paclitaxel contain surfactants and solvents or albumin derived from human blood. The use of co-solvents such as polyoxyethylated castor oil is thought to contribute to toxicity profile and hypersensitivity reactions as well as leaching of plasticizers from polyvinyl chloride bags and infusion sets. Currently, nab-paclitaxel, an albumin-bound paclitaxel in nanometer range continues to be the preferred taxane formulation used in clinic. This study (CTRI/2010/091/001116) investigated the efficacy and tolerability of a polyoxyethylated castor oil- and albumin-free formulation of paclitaxel [paclitaxel injection concentrate for nanodispersion (PICN)] compared with nab-paclitaxel in women with refractory MBC. The current study was a multicenter, open-label, parallel-group, randomized, comparative phase II/III trial evaluating the efficacy and safety of PICN (260 mg/m(2) [n = 64] and 295 mg/m(2) [n = 58] every 3 weeks) compared with nab-paclitaxel (260 mg/m(2) every 3 weeks [n = 58]) in women 18 and 70 years old with confirmed MBC. Overall response rate (ORR) was assessed with imaging every 2 cycles. An independent analysis of radiologic data was performed for evaluable patients. Progression-free survival (PFS) was a secondary efficacy measure. Independent radiologist-assessed ORRs in the evaluable population of women aged ≥70 years were 35, 49, and 43 % in the PICN 260 mg/m(2), PICN 295 mg/m(2), and nab-paclitaxel 260 mg/m(2) arms, respectively. Median PFS in the evaluable population was 23, 35, and 34 weeks in the PICN 260 mg/m(2), PICN 295 mg/m(2), and nab-paclitaxel 260 mg/m(2) arms, respectively. Adverse events occurred in similar proportions of patients across treatment arms. Hypersensitivity reactions were not frequently observed with the clinical use of PICN across the treatment cohorts. In women with metastatic breast cancer, PICN at 260 and 295 mg/m(2

  1. COMPARISON OF RNA EXTRACTION METHODS FOR Passiflora edulis SIMS LEAVES

    Directory of Open Access Journals (Sweden)

    ANNY CAROLYNE DA LUZ

    2016-02-01

    Full Text Available ABSTRACT Functional genomic analyses require intact RNA; however, Passiflora edulis leaves are rich in secondary metabolites that interfere with RNA extraction primarily by promoting oxidative processes and by precipitating with nucleic acids. This study aimed to analyse three RNA extraction methods, Concert™ Plant RNA Reagent (Invitrogen, Carlsbad, CA, USA, TRIzol® Reagent (Invitrogen and TRIzol® Reagent (Invitrogen/ice -commercial products specifically designed to extract RNA, and to determine which method is the most effective for extracting RNA from the leaves of passion fruit plants. In contrast to the RNA extracted using the other 2 methods, the RNA extracted using TRIzol® Reagent (Invitrogen did not have acceptable A260/A280 and A260/A230 ratios and did not have ideal concentrations. Agarose gel electrophoresis showed a strong DNA band for all of the Concert™ method extractions but not for the TRIzol® and TRIzol®/ice methods. The TRIzol® method resulted in smears during electrophoresis. Due to its low levels of DNA contamination, ideal A260/A280 and A260/A230 ratios and superior sample integrity, RNA from the TRIzol®/ice method was used for reverse transcription-polymerase chain reaction (RT-PCR, and the resulting amplicons were highly similar. We conclude that TRIzol®/ice is the preferred method for RNA extraction for P. edulis leaves.

    2010-05-28

    There is increased use of nanomaterials in many applications due to their unique properties, such as their high surface area and surface reactivity. However, the potential health effects to workers, consumers and the environment exposed to nanoparticles (NPs) is unknown. The aim of this study was to investigate whether NPs which may enter the body could adsorb proteins and whether this interaction affects both the particle and the protein function. The cytokines IL-8 and TNF-{alpha} were adsorbed significantly more by 14 nm carbon black (CB) compared with a similar dose of 260 nm CB. Uncoated 14 nm CB particles produced a significant increase in intracellular calcium [Ca{sup 2+}]{sub i} which was greater than a similar mass dose of 260 nm CB. The 260 nm CB produced an increase in ICAM-1 expression in A549 epithelial cells at a comparable dose of 14 nm CB, and after coating with TNF-{alpha} 260 nm CB produced significantly more ICAM-1 expression compared with control cells. TNF-{alpha} bound to 14 nm CB induced a level of ICAM-1 expression that was no greater than the control level, suggesting that the TNF-{alpha} activity may be inhibited. These results suggest that NP-protein interaction results both in a decrease in protein function and particle activity in the cellular assays tested and this is currently being investigated.

    Wistar rats were treated with 7.8 or 260 nmols T4/100 g BW, 1.5 or 260 nmols T3/100 g BW, or saline as control. Twenty minutes later 1 μg TRH/100 g BW was injected iv. Heparinized blood samples were drawn at times 0 and 30 minutes (10 min post-TRH) for determination of plasma TSH, T4 and T3 by RIA. Other group of rats were administered with 150 μCi of 3',5'- 125I-T4 prepared by iodination of 3,5-diiodothyronine. Thirty minutes later the hypophyses were removed, and chromatographed. Other group of animals were treated with 5 mg of iopanoic acid (IOP)/100 g BW. Thereafter, rats were injected iv with 260 nmols T4 or T3/100 g BW and the TRH-test performed as described above. In the control group there was a 11-fold increase in plasma TSH at 10 minutes post-TRH. In rats treated with 260 nmols T4 the post-TRH increment in plasma TSH was 5+-1-fold (p125I-T3 in the hypophyses 30 minutes after 125I-T4 administration. The present data indicate that T4 is capable of depressing the release of TSH in response to TRH stimulation in normal rats. (M.E.L.)

    Feline vector-borne diseases can be caused by a range of pathogens transmitted by arthropods. Many of these infections have zoonotic implications, and stray cats are potential sentinels for human and pet health. This study investigated the prevalence of selected vector-borne infections in stray colony cats in Milan. Blood samples from 260 stray cats were evaluated, using conventional polymerase chain reaction tests (cPCRs), for the presence of DNA associated with Rickettsia species, Anaplasma phagocytophilum and Ehrlichia species. Positive cPCR results occurred in 127/260 subjects (48.9%; 95% confidence interval [CI] = 40.7-58.1), with a prevalence of 31.9% (83/260, 95% CI = 25.4-39.6) for Rickettsia species, 17.7% (46/260, 95% CI= 13.0-23.6) for A phagocytophilum, and 5.4% (14/260, 95% CI = 2.9-9.0) for Ehrlichia species. There was no statistical association between a positive PCR test for vector-borne infections surveyed and colony location, age, gender, body condition score or complete blood count abnormalities, nor feline immunodeficiency virus, feline leukaemia virus or Toxoplasma gondii status. The only variable linked to positive PCR results was detection of signs of ocular infection and PCR positivity for Rickettsia species (P = 0.04, odds ratio [OR] = 2.2, 95% CI = 1.1-4.4, P = 0.02). There is a significant prevalence of vector-borne infections with zoonotic potential in urban stray cats in Milan. Thus, dogs and pet cats with outdoor access should be monitored and treated for ectoparasites on a regular basis to minimise risks of disease and the potential transmission of zoonotic agents to people.

  9. Dependence of thermoluminescence in LiF:Mg,Cu,Na,Si phosphor on Na dopant concentration and thermal treatment

    International Nuclear Information System (INIS)

    A new phosphor, LiF:Mg,Cu,Na,Si, has been developed in this laboratory for thermoluminescence. The thermoluminescence dependence on the concentration of Na dopant between 0 mol% and 0.45 mol% and thermal treatment between 240 deg. C and 310 deg. C was investigated. With an increase of Na concentration, the TL sensitivity and the main peak increase when the annealing temperature is less than 300 deg. C. With an increase of annealing temperature, the position of the main glow peak shifts markedly towards higher temperatures, irrespective of Na concentrations. The height of the main peak depends strongly on the annealing temperature. TL sensitivity remains stable at annealing temperatures from 260 deg. C to 300 deg. C for 0 mol% Na concentration, from 250 deg. C to 300 deg. C for 0.05 mol% N concentration, from 260 deg. C to 290 deg. C for 0.1 mol% Na concentration, from 260 deg. C to 280 deg. C for 0.2 mol% Na concentration, from 250 deg.C to 270 deg. C for 0.35 mol% Na concentration, or from 260 deg. C to 280 deg. C for 0.45 mol% Na concentration. The ratio of the intensity annealed at 310 deg. C to the intensity annealed at 260 deg. C seems to be reduced with an increase of Na concentration. Thermal susceptibility of LiF:Mg,Cu,Na,Si appears to be associated with the Na concentration. The lower the Na concentration, the less sensitive the TL is to annealing temperature. The optimum Na dopant concentration was found to be 0%

  10. Effects of chilling and ABA on [3H]gibberellin A4 metabolism in somatic embryos of grape (Vitis vinifera L. x V. rupestris Scheele)

    International Nuclear Information System (INIS)

    Previous work has indicated that changes in gibberellin (GA) metabolism may be involved in chilling-induced release from dormancy in somatic embryos of grape (Vitis vinifera L. x V. rupestris Scheele). The authors have chilled somatic embryos of grape for 2, 4, or 8 weeks, then incubated them with [3H]GA4 (of high specific activity, 4.81 x 1019 becquerel per millimole) for 48 hours at 260C. Chilling had little effect on the total amount of free [3H]GA-like metabolites formed during incubation at 260C, but did change the relative proportions of individual metabolites. The amount of highly water-soluble [3H] metabolites formed at 260C decreased in embryos chilled for 4 or 8 weeks. The concentration of endogeneous GA precursors (e.g., GA12 aldehyde-, kaurene, and kaurenoic acid-like substances) increased in embryos chilled for 4 or 8 weeks. Treatment with abscisic acid (ABA) (known to inhibit germination in grape embryos) concurrent with [3H]GA4 treatment at 260C, reduced the uptake of [3H] GA4 but had little effect on the qualitative spectrum of metabolites. However, in the embryos chilled for 8 weeks and then treated with ABA for 48 hours at 260C, there was a higher concentration of GA precursors than in untreated control embryos. Chilled embryos thus have an enhanced potential for an increase in free GAs through synthesis from increased amounts of GA precursors, or through a reduced ability to form highly water-soluble GA metabolites (i.e., GA conjugates or polyhydroxylated free GAs)

    Highlights: • The Cu{sub 2}O NCs/TiO{sub 2} PC composite was synthesized and exhibited high photocatalysis. • The improved light harvesting and increased quantum yield was achieved. • The hydroxyl radical was the primary oxidant in Cu{sub 2}O NCs/TiO{sub 2} PC photocatalysis. - Abstract: A 3D UV–visible light responsive photocatalyst was fabricated by infiltrating Cu{sub 2}O nanocrystals (NCs) into TiO{sub 2} photonic crystal (PC). Morphology characterization presented that Cu{sub 2}O NCs with average diameter around 10 nm were dispersed uniformly into TiO{sub 2} PC. The transmittance spectra showed that Cu{sub 2}O NCs/TiO{sub 2} 260, prepared by integrating Cu{sub 2}O NCs with TiO{sub 2} 260 which was fabricated from 260 nm polystyrene spheres, exhibited the highest light harvesting. The photoluminescence spectra confirmed the electron/hole pairs recombination of Cu{sub 2}O NCs/TiO{sub 2} 260 was efficiently inhibited due to the unique heterojunction structure between TiO{sub 2} and Cu{sub 2}O. In the photocatalytic degradation of Rhodamine B and Bisphenol A under UV–visible light (320 nm < λ < 780 nm) irradiation, the kinetic constant using Cu{sub 2}O NCs/TiO{sub 2} 260 was 3.99 and 8.37-fold larger than that using TiO{sub 2} nanoparticle (NP), respectively. The enhanced photocatalysis benefited from the increased light harvesting owing to the excitation of both TiO{sub 2} and Cu{sub 2}O NCs whose optical absorption was intensified by the photonic effect of TiO{sub 2} 260 and the high quantum efficiency due to the Cu{sub 2}O/TiO{sub 2} heterojunction. The hydroxyl radical, generated from the protonation of superoxide radical which was derived from the reduction of oxygen by photogenerated electrons, was the main oxidant responsible for pollutant degradation.

    Neon hydrate was synthesized and studied by in situ neutron diffraction at 480 MPa and temperatures ranging from 260 to 70 K. For the first time to our knowledge, we demonstrate that neon atoms can be enclathrated in water molecules to form ice II-structured hydrates. The guest Ne atoms occupy the centers of D2O channels and have substantial freedom of movement owing to the lack of direct bonding between guest molecules and host lattices. Molecular dynamics simulation confirms that the resolved structure where Ne dissolved in ice II is thermodynamically stable at 480 MPa and 260 K. The density distributions indicate that the vibration of Ne atoms is mainly in planes perpendicular to D2O channels, whereas their distributions along the channels are further constrained by interactions between adjacent Ne atoms.

    An analysis is presented of solar ultraviolet irradiance measurements made by the SOLSTICE spectrometers on the Upper Atmosphere Research Satellite (UARS). Reported observations cover the wavelength interval 119-420 nm, and the analysis discussed here is for the time period 26 Nov 1991 to 31 Dec 1992, during which time solar activity decreased in intensity. At the time of peak activity, the average 27-day variation had a relative amplitude of about 8 percent at Ly-alpha, tailing off to about 0.6 percent at 260 nm. It is shown that over the spectral interval 119-260 nm, the relative 27-day harmonic was about a factor of two larger during the strongly disturbed as compared with the moderately disturbed period.

    International Nuclear Information System (INIS)

    Hydrated starch alone and in composition with nanosilica A-300 and quercetin (natural antioxidant) was studied in the form of powders (mechanical mixture) and gels using 1H NMR (at 200-280 K), FTIR (293 K), TG (293-573 K), TSDC (90-265 K) and quantum chemistry methods. Influence of weakly polar (chloroform-d, CDCl3) and polar ((CD3)2SO, DMSO) deuterated solvents on bound water structure in these systems was also analysed at 200-280 K. The energetic and structural boundaries between weakly (unfrozen at 250-260 < T < 273 K) and strongly (unfrozen at 200 < T < 250-260 K) bound waters become nonabrupt after the addition of these solvents to quercetin/starch/nanosilica composites because of the differences in water interaction with these substances differently affecting its freezing point depression.

    Crustal Movement Observation Network of China (CMONOC) is a key national scientific infrastructure project carried out during 1997-2012 with 2 phases. The network is composed of 260 continuously observed GNSS stations (CORS) and 2081 campaign mode GNSS stations, with the main purpose to monitor the crustal movement, perceptible water vapor (PWV), total electron content (TEC), and many other tectonic and environmental elements around mainland China, by mainly using the Global Navigation Satellite System (GNSS) technology. Here, based on the GNSS data of 260 CORS of COMNOC for about 5 years, we investigated the characteristics of TEC in ionosphere over Chinese Mainland and discussed if there was any abnormal change of TEC before and after a big earthquake. our preliminary results show that it is hard to see any convincing precursor of TEC before a big earthquake. However, the huge energy released by a big earthquake can obviously disturb the TEC over meizoseismal area.

  2. Materials Issues in High Temperature Ultrasonic Transducers for Under-Sodium Viewing

    International Nuclear Information System (INIS)

    Liquid sodium is used as the coolant in some fast spectrum nuclear reactors. This material is optically opaque. To facilitate operations and maintenance activities, an ultrasonic under-sodium viewing system has been developed. In the USA, the technology was successfully demonstrated in the 1970's, and, over the intervening 30+ years the capability was lost. This paper reports materials challenges encountered in developing both single-element and linear phased array 2 MHz transducers that must operate at temperatures up to 260C. The critical issues are fundamentally material selection: the ability of a transducer to be immersed into liquid sodium and function at 260C, to achieve wetting and transmission of ultrasound into the sodium, and to be able to be removed and re-used.

    In yeast, the inositolphosphorylceramides mostly contain C26:0 fatty acids. Inositolphosphorylceramides were considered to be important for viability, since the inositolphosphorylceramide synthase AUR1 is essential. Yet, lcb1 cells, unable to make sphingoid bases and inositolphosphorylceramides, ......, are viable if they harbor SLC1-1, a gain of function mutation in the 1-acyl-glycerol-3-phosphate acyltransferase SLC1. SLC1-1 allows to incorporate C26:0 fatty acids into phosphatidylinositol (PI), thus generating PIii, an abnormal, C26-containing PI, presumably acting as surrogate...... genetic backgrounds but to still make some abnormal uncharacterized inositol-containing sphingolipids. Indeed, we find that 4 quadruple mutants make substantial amounts of unphysiological inositolphosphorylphytosphingosines but that they also still make small amounts of normal inositolphosphorylceramides...

    2006-04-01

    Economic valuation of environmental goods or services has been becoming a research frontier and hotspot of environmental economics in the world. Choice experiment (CE) is a relatively new method that can be used to value the economic benefits of environmental goods or services. This paper reports an attempt to apply the CE method in Macao that aimed to understand Macao residents' preferences for solid waste management programs. A random sample survey of 260 respondents in Macao was conducted during the summer in 2004. Survey data was analyzed using multinomial logit models. Results from 260 in-person interviews indicate that Macao residents preferred waste segregation and recycling at source and noise reduction during waste collection and transportation. The study concludes that CE is a reliable tool in the analysis of respondents' preferences for the development of suitable solid waste management programs in Macao. PMID:16768014

    Torrefaction of cedarwood was performed in a pilot-scale rotary kiln at various temperatures (200, 230, 260 and 290°C). The torrefaction properties, the influence on the grindability and hydroscopicity of the torrefied biomass were investigated in detail as well as the combustion performance. It turned out that, compared with raw biomass, the grindability and the hydrophobicity of the torrefied biomass were significantly improved, and the increasing torrefaction temperature resulted in a decrease in grinding energy consumption and an increase in the proportion of smaller-sized particles. The use of industrial flue gas had a significant influence on the behavior of cedarwood during torrefaction and the properties of the resultant solid products. To optimize the energy density and energy yield, the temperature of torrefaction using flue gas should be controlled within 260°C. Additionally, the combustion of torrefied samples was mainly the combustion of chars, with similar combustion characteristics to lignite.

    Extraction of genomic DNA from various types of samples is often challenging for commercial silica spin column. In this study, we proposed graphite oxide (GO)/cellulose composite as an alternative material for genomic DNA extraction. The purity of DNA and extraction efficiency were compared to that of commercial silica product. In this study, the total weight % of GO was fixed at 4.15% in GO/Cellulose composite. Chewed gum, nail clip, cigarette bud paper, animal tissue and hair sample were used as various genomic DNA sources for extraction experiments. Among all types of samples, the extraction efficiencies were 4 to 12 times higher than that of commercial silica spin column. The absorbance ratio of 260 nm to 280 nm (A260/A280) of all samples ranged between 1.6 and 2.0. The results demonstrated that GO/Cellulose composites might serve as an innovative solid support material for genomic DNA extraction.

    “The inclusion of article 260(3) TFEU adopted as part of the Lisbon Treaty changed the landscape of infringement proceedings. The provision grants the Commission the power to propose monetary sanctions already during the initial Court litigation against a Member State that ‘failed to notify......’ national measures transposing a directive. This article analyses the concept of ‘failure to notify’ and points out that the current interpretation adopted by the Commission is only one of several possible interpretations. The author concludes that article 260(3) TFEU as it stands now is vaguely drafted and...... is prone to lead to judicial uncertainty. It further increases the already heavily criticized Commission discretion. Furthermore, the lack of proper guidelines of what constitutes ‘failure to notify’ can lead to the arbitrary launching of non-communication proceedings as well as further complicate...

  13. Involvement of a low-lying Rydberg state in the ultrafast relaxation dynamics of ethylene

    International Nuclear Information System (INIS)

    We present a measurement of the time-resolved photoelectron kinetic energy spectrum of ethylene using 156 nm and 260 nm laser pulses. The 156 nm pulse first excites ethylene to the 1B1u (ππ∗) electronic state where 260 nm light photoionizes the system to probe the relaxation dynamics with sub-30 fs resolution. Recent ab initio calculations by Mori et al. [J. Phys. Chem. A 116, 2808-2818 (2012)] have predicted an ultrafast population transfer from the initially excited state to a low-lying Rydberg state during the relaxation of photoexcited ethylene. The measured photoelectron kinetic energy spectrum reveals wave packet motion on the valence state and shows indications that the low-lying π3s Rydberg state is indeed transiently populated via internal conversion following excitation to the ππ∗ state, supporting the theoretical predictions

    Full Text Available Snodgrass & Vanderwart (1980 standardized a set of 260 pictures in the USA for use in studies of cognitive processes that employ pictured objects as laboratory analogues of object themselves. Since then similar norms for this set were obtained in Britain, Spain, Japan and Iceland and a larger set of 400 pictures (including the original 260: Cycowicz et al., 1997 was studied in France and Brazil. The present article provides a comparison of the norms obtained in Brazil and internationally. The pattern of correlations among the Brazilian and other standardizations were equivalent to that previously observed: despite pictures being judged to be of similar familiarity and visual complexity (high positive correlations, name agreement was less correlated, possibly due to differences in the languages spoken in each country and/or in the sample size used in each study. Results confirm the adequacy of the Brazilian norms.

  17. Study of residual electric resistance restoring in irradiated and deformed vessel steel

    International Nuclear Information System (INIS)

    Investigation into residual electric resistance (RER) restoring under isochronous and isothermal annealing of 15Kh2MFA pearlitic steel irradiated at 260 and 220 deg C has been represented in the paper RER restoring occurs, mainly, during two stages, at that a RER restoring value depends on irradiation temperature. Thermoactivation analysis and results of studying the fracture surface of hydrogenated steel permit to affirm that pearlitic steel irradiation at the given temperatures leading to RER drop in a certain measure is related to formation of phosphorus grain-boundary aggregations. It is established that the deformation of steel irradiated at a temperature of about 260 deg C causes additive RER change, which permits to suggest schemes for solution of some practical problems

    Based on the joint-observations of the radio broadband spectral emissions of solar eclipse on August 1, 2008 at Jiuquan (total eclipse) and Huairou (partial eclipse) at the frequencies of 2.00 -- 5.60 GHz (Jiuquan), 2.60 -- 3.80 GHZ (Chinese solar broadband radiospectrometer, SBRS/Huairou), and 5.20 -- 7.60 GHz (SBRS/Huairou), the authors assemble a successive series of broadband spectrum with a frequency of 2.60 -- 7.60 GHz to observe the solar eclipse synchronously. This is the first attempt to analyze the solar eclipse radio emission under the two telescopes located at different places with broadband frequencies in the periods of total and partial eclipse. With these analyses, the authors made a new semiempirical model of the coronal plasma density of the quiet Sun and made a comparison with the classic models.

    The Song Ma zone in NW Vietnam bears important tectonic implications as a potential subduction corridor between the Indochina and South China blocks. On the basis of U-Pb ages, the Hf isotopic characteristics of zircons and the geochemical composition of granitoids, a two-stage magmatic evolution process of the Song Ma zone at ~290-260 and ~245-230 Ma can be proposed. Isotopic analyses indicate magmatic contributions from Neoproterozoic oceanic island basalt, Proterozoic continental crust, and depleted mantle or juvenile lithosphere. By combining geochronological and geochemical data from the granitoid rocks, we suggest that the staged magmatic processes of Song Ma zone may be related to a long-lasting period of ocean subduction (ca. 290-260 Ma) and subsequent syn-/post-collisional evolution (ca. 245-230 Ma).
