Abstract

In recent attempts to search for exotic shapes, hyperdeformation (HD), and Jacobi transitions in Hf, Ba, Xe, Sn and Nd nuclei, ridge structures presumably originating from nuclei of very elongated shapes have been observed in 126Ba, with Gammasphere (GS) and in 126Xe, with Euroball-IV (EB-IV). After the promising results from GS, a second experiment in 126Ba followed at EB-IV, taking advantage of the use of the BGO Inner Ball (IB) for selecting the highest spins. The decay of the Giant Dipole Resonances (GDR) is also studied, and the analysis in progress. The Quasi-continuum transitions in the Jacobi region, show a significant decrease in energy for both 126Ba and 126Xe, compared to the Thomas-Fermi- and the LSD model predictions. Similar effects were recently found for other nuclei by Ward et al.

Abstract

The next generation of 4π arrays for high-precision γ-ray spectroscopy AGATA will consist of γ-ray tracking detectors. They represent high-fold segmented Ge detectors and a front-end electronics, based on digital signal processing techniques, which allows to extract energy, timing and spatial information on the interactions of a γ-ray in the Ge detector by pulse shape analysis of its signals. Utilizing the information on the positions of the interaction points and the energies released at each point the tracks of the γ-rays in a Ge shell can be reconstructed in three dimensions on the basis of the Compton-scattering formula.

Abstract

Conventional methods for detecting indicator and pathogenic bacteria in water may underestimate the actual population due to sublethal environmental injury, inability of the target bacteria to take up nutrients and other physiological factors which reduce bacterial culturability. Rapid and direct methods are needed to more accurately detect and enumerate active bacteria. Such a methodological advance would provide greater sensitivity in assessing the microbiological safety of water and food. The principle goal of this presentation is to describe novel approaches we have formulated for the rapid and simultaneous detection of bacteria plus the determination of their physiological activity in water and other environmental samples. The present version of our method involves the concentration of organisms by membrane filtration or immunomagnetic separation and combines an intracellular fluorochrome (CTC) for assessment of respiratory activity plus fluorescent-labelled antibody detection of specific bacteria. This approach has also been successfully used to demonstrate spatial and temporal heterogeneities of physiological activities in biofilms when coupled with cryosectioning. Candidate physiological stains include those capable of determining respiratory activity, membrane potential, membrane integrity, growth rate and cellular enzymatic activities. Results obtained thus far indicate that immunomagnetic separation can provide a high degree of sensitivity in the recovery of seeded target bacteria (Escherichia coli O157:H7) in water and hamburger. The captured and stained target bacteria are then enumerated by either conventional fluorescence microscopy or ChemScan(R), a new instrument that is very sensitive and rapid. The ChemScan(R) laser scanning instrument (Chemunex, Paris, France) provides the detection of individual fluorescently labelled bacterial cells using three emission channels in less than 5 min. A high degree of correlation has been demonstrated between results obtained with the ChemScan and traditional plate counts of mixed natural bacterial populations in water. The continuing evolution of these methods will be valuable in the rapid and accurate analysis of environmental samples.

Abstract

Escherichia coli O157:H7 can persist for days to weeks in microcosms simulating natural conditions. In this study, we used a suite of fluorescent, in situ stains and probes to assess the influence of starvation on physiological activity based on membrane potential (rhodamine 123 assay), membrane integrity (LIVE/DEAD BacLight kit), respiratory activity (5-cyano-2,3-di-4-tolyl-tetrazolium chloride assay), intracellular esterase activity (ScanRDI assay), and 16S rRNA content. Growth-dependent assays were also used to assess substrate responsiveness (direct viable count [DVC] assay), ATP activity (MicroStar assay), and culturability (R2A agar assay). In addition, resistance to chlorine disinfection was assessed. After 14 days of starvation, the DVC values decreased, while the values in all other assays remained relatively constant and equivalent to each other. Chlorine resistance progressively increased through the starvation period. After 29 days of starvation, there was no significant difference in chlorine resistance between control cultures that had not been exposed to the disinfectant and cultures that had been exposed. This study demonstrates that E. coli O157:H7 adapts to starvation conditions by developing a chlorine resistance phenotype.

25. Microbial formation of labile organic carbon in Antarctic glacial environments

Author

Smith, H. J., Foster, Rachel A., McKnight, D. M., Lisle, J. T., Littmann, S., Kuypers, M. M. M., Foreman, C. M., Smith, H. J., Foster, Rachel A., McKnight, D. M., Lisle, J. T., Littmann, S., Kuypers, M. M. M., and Foreman, C. M.

Abstract

Roughly six petagrams of organic carbon are stored within ice worldwide. This organic carbon is thought to be of old age and highly bioavailable. Along with storage of ancient and new atmospherically deposited organic carbon, microorganisms may contribute substantially to the glacial organic carbon pool. Models of glacial microbial carbon cycling vary from net respiration to net carbon fixation. Supraglacial streams have not been considered in models although they are amongst the largest ecosystems on most glaciers and are inhabited by diverse microbial communities. Here we investigate the biogeochemical sequence of organic carbon production and uptake in an Antarctic supraglacial stream in the McMurdo Dry Valleys using nanometre-scale secondary ion mass spectrometry, fluorescence spectroscopy, stable isotope analysis and incubation experiments. We find that heterotrophic production relies on highly labile organic carbon freshly derived from photosynthetic bacteria rather than legacy organic carbon. Exudates from primary production were utilized by heterotrophs within 24 h, and supported bacterial growth demands. The tight coupling of microbially released organic carbon and rapid uptake by heterotrophs suggests a dynamic local carbon cycle. Moreover, as temperatures increase there is the potential for positive feedback between glacial melt and microbial transformations of organic carbon.

Abstract

The lifetimes of eight lower spin levels of the yrast band in Yb-168, populated via the Sm-154(O-18,4n) and Sn-124(Ca-48,4n) reactions, were measured, six of them for the first time, by means of the recoil-distance Doppler-shift method. Two versions of the differential decay-curve method have been applied for the data analysis resulting in a very good agreement. The reduced transition probabilities indicate some reduction of the collectivity for states just above the 6(1)(+) level, i.e. well below the band-crossing. The reasons of this effect are discussed in terms of an interaction between the ground-state band and yet unknown part of the two-quasiparticle (nu(13/2)) spin-aligned S-band by invoking the shell-structure or alternatively/additionally, as changes in the internal structure/shape induced by the rotation.

Abstract

The West Florida Shelf (WFS) is a source of uncertainty for the Gulf of Mexico carbon budget. Data from the synthesis of approximately 135,000 pCO2 values from 97 cruises from the WFS show that the shelf waters fluctuate between being a weak source to a weak sink of carbon. Overall, the shelf acts as a weak source of CO2 at 0.32 ± 1.5 mol m−2 yr−1. Subregions, however, reveal slightly different trends, where surface waters associated with 40–200‐m isobath in the northern and southern WFS are generally weak sinks all year, except for summer when they act as sources of CO2. Conversely, nearshore waters (<40 m) are a source of CO2, particularly the southern shallow waters, which are a source all year round. The pCO2 of seawater has been increasing at a rate of approximately 4.37 μatm/year as compared to atmospheric pCO2 which has increased at a rate of about 1.7 μatm per year from 1996 to 2016. The annual CO2 flux has increased from −0.78 to 0.92 mol m−2 yr−1 on the shelf from 1996–2016. The WFS is emitting 9.23 Tg C/year, with the southern nearshore region emitting the most at 9.01 Tg C/year and the northern region acting as a sink of −1.96 Tg C/year. Aragonite saturation state on the WFS shows seasonal and geographic trends with values ranging from 2 to 5. Lowest values are found in winter associated with subregion <40‐m isobath. Plain Language Summary: The West Florida Shelf (WFS) is a source of uncertainty for determining the Gulf of Mexico carbon budget and how surface waters are being affected by increasing atmospheric carbon dioxide (CO2) levels. Little is known about the WFS trends of the seawater partial pressure of carbon dioxide (pCO2) over the last decades; much of the uncertainty stems from lack of data. In order to address some of this uncertainty, approximately 135,000 pCO2 values collected on 97 research cruises between 1996 and 2016 were analyzed and show that the shelf waters have changed from being a weak sink to weak source of CO2 to the atmosphere. Further, data was divided into four geographical subregions. Offshore surface waters absorb CO2, whereas nearshore surface waters emit CO2 to the atmosphere. Importantly, pCO2 of the nearshore seawater has been increasing at a rate approximately 2.5 times faster than atmospheric pCO2 over the past 20 years. These data indicate that factors in addition to the atmosphere CO2 are influencing increases in nearshore seawater. Additionally, WFS aragonite saturation state, often used to monitor ocean acidification conditions, shows seasonal and geographic trends, with year‐round supersaturated values ranging from 2 to 5. Key Points: WFS surface water shows a change from carbon sink to source from 1996 to 2016The WFS emits 9.23 Tg C/year, with the south nearshore emitting the most at 9.01 Tg C/year and the north acting as a sink of −1.96 Tg C/yearShelf water (<40‐m isobath) pCO2 has increased at a rate approximately 2.6 times faster than the atmospheric rate in the past 20 years [ABSTRACT FROM AUTHOR]

Abstract

The gamma decay of the nuclei 124,125Ba has been investigated by means of the EUROBALL spectrometer, coupled to the DIAMANT array of charged-particle detectors, using the reaction 64Ni + 64Ni at E_{beam}=255 and 261 MeV. In the nucleus 125Ba six new E1 transitions have been found to link opposite-parity bands currently interpreted as \nu d_{5/2(+g_{7/2},nu h_11/2}structures. The previously unknown Jpi=3- level in the nucleus $^{124}$Ba has also been identified; its excitation energy is accurately reproduced by a microscopic calculation including octupole correlations. Both issues are bolstered by sizable B(E1)/B(E2) ratios.

Abstract

The West Florida Shelf (WFS) is a source of uncertainty for the Gulf of Mexico carbon budget. Data from the synthesis of approximately 135,000 pCO2values from 97 cruises from the WFS show that the shelf waters fluctuate between being a weak source to a weak sink of carbon. Overall, the shelf acts as a weak source of CO2at 0.32 ± 1.5 mol m−2yr−1. Subregions, however, reveal slightly different trends, where surface waters associated with 40–200‐m isobath in the northern and southern WFS are generally weak sinks all year, except for summer when they act as sources of CO2. Conversely, nearshore waters (<40 m) are a source of CO2, particularly the southern shallow waters, which are a source all year round. The pCO2of seawater has been increasing at a rate of approximately 4.37 μatm/year as compared to atmospheric pCO2which has increased at a rate of about 1.7 μatm per year from 1996 to 2016. The annual CO2flux has increased from −0.78 to 0.92 mol m−2yr−1on the shelf from 1996–2016. The WFS is emitting 9.23 Tg C/year, with the southern nearshore region emitting the most at 9.01 Tg C/year and the northern region acting as a sink of −1.96 Tg C/year. Aragonite saturation state on the WFS shows seasonal and geographic trends with values ranging from 2 to 5. Lowest values are found in winter associated with subregion <40‐m isobath. The West Florida Shelf (WFS) is a source of uncertainty for determining the Gulf of Mexico carbon budget and how surface waters are being affected by increasing atmospheric carbon dioxide (CO2) levels. Little is known about the WFS trends of the seawater partial pressure of carbon dioxide (pCO2) over the last decades; much of the uncertainty stems from lack of data. In order to address some of this uncertainty, approximately 135,000 pCO2values collected on 97 research cruises between 1996 and 2016 were analyzed and show that the shelf waters have changed from being a weak sink to weak source of CO2to the atmosphere. Further, data was divided into four geographical subregions. Offshore surface waters absorb CO2, whereas nearshore surface waters emit CO2to the atmosphere. Importantly, pCO2of the nearshore seawater has been increasing at a rate approximately 2.5 times faster than atmospheric pCO2over the past 20 years. These data indicate that factors in addition to the atmosphere CO2are influencing increases in nearshore seawater. Additionally, WFS aragonite saturation state, often used to monitor ocean acidification conditions, shows seasonal and geographic trends, with year‐round supersaturated values ranging from 2 to 5. WFS surface water shows a change from carbon sink to source from 1996 to 2016The WFS emits 9.23 Tg C/year, with the south nearshore emitting the most at 9.01 Tg C/year and the north acting as a sink of −1.96 Tg C/yearShelf water (<40‐m isobath) pCO2has increased at a rate approximately 2.6 times faster than the atmospheric rate in the past 20 years

Abstract

The next generation of 4π arrays for high-precision γ-ray spectroscopy AGATA will consist of γ-ray tracking detectors. They represent high-fold segmented Ge detectors and a front-end electronics, based on digital signal processing techniques, which allows to extract energy, timing and spatial information on the interactions of a γ-ray in the Ge detector by pulse shape analysis of its signals. Utilizing the information on the positions of the interaction points and the energies released at each point the tracks of the γ-rays in a Ge shell can be reconstructed in three dimensions on the basis of the Compton-scattering formula.

Abstract

Is an image without frame possible ? The nowadays virtual realities could induce us to believe it, since the worlds they offer seem to have broken the usual limits of image. This article, on the contrary, tries to point that the notion of frame, although it can be reconsidered, remains one of the necessary conditions of representation.

Abstract

8 pages; Two new rotational bands have been observed in the 152Dy nucleus following experiments performed using the EUROGAM gamma -ray spectrometer. Several transitions have been observed that link these new bands into the known single-particle states. Using the Doppler shift attenuation method, the quadrupole moment of the previously-known rotational sequence has been measured. The value of Qband=3.85±0.06 e b confirms the deformed nature of this cascade. The structures of the three bands are discussed in terms of the occupation of both paired and unpaired orbitals, and are found to be in good agreement with theoretical calculations. The observation of two new bands further extends the concept of shape coexistence in the 152Dy nucleus.

Abstract

The gamma decay of the nuclei Ba-121,Ba-125 has been investigated with the EUROBALL array, using the reaction Ni-64+Ni-64 at E-beam = 255 and 261 MeV. Six new E1 transitions have been found in the nucleus Ba-125, suggesting a significant role of octupole correlations in the origin of its parity doublets. The J(pi) = 3(-) level of the nucleus Ba-124 has been identified for the first time. Its excitation energy is in very good agreement with a prediction based on a microscopic model including octupole interactions., QC 20141202
