Proposal of \u3cem\u3eVibrionimonas magnilacihabitans\u3c/em\u3e gen. nov., sp. nov., a Curved Gram Negative Bacterium Isolated From Lake Michigan Water

A mesophilic bacterium appearing as curved rod-shaped cells was isolated from Lake Michigan water. It exhibited highest similarities with Sediminibacterium ginsengisoli DCY13T (94.4 %); Sediminibacterium salmoneum NJ-44T (93.6 %) and Hydrotalea flava CCUG 51397 T (93.1 %) while similarities with other recognized species were sym-homospermidine was the primary polyamine. The major cellular fatty acids were iso-C15 : 1G, iso-C15 : 0, iso-C16 : 0 3-OH and iso-C17 : 0 3-OH, with moderate amounts of iso-C16 : 0. The presence of glycolipids differentiated the novel strains from related genera. The DNA mol% G+C content of the type strain MU-2T was 45.2. Results for other phenotypic and molecular analyses indicated that strain MU-2T is a representative of a novel genus and species for which the name Vibrionimonas magnilacihabitans is proposed. The type strain is MU-2T ( = NRRL B-59231 = DSM 22423)

Reakcija 133Cs(d, 3He)132Xe

The 133Cs(d, 3He)132Xe reaction was measured at the Munich Q3D magnetic spectrograph with high resolution. The spectra were obtained at beam energies of Ed = 27 MeV and Ed = 28 MeV. The corresponding angles of the spectrograph were 30◦ and 50◦ , respectively. The achieved FWHM was between 7 keV and 10 keV and the energies of the levels could be determined with a precision between 0.5 keV and 1 keV.Pomoću Q3D magnetskog spektrografa istraživali smo reakciju 133Cs(d, 3He)132Xe pri visokom razlučivanju. Izmjereni su spektri za energiju upadnih deuterona od 27 i 28 MeV, na kutovima raspršenja 30◦ odnosno 50◦ . Postignuto je razlučivanje između 7 i 10 keV, a energije stanja u 132Xe su određene na točnost između 0.5 i 1 keV

Plutonium release from Fukushima Daiichi fosters the need for more detailed investigations

The contamination of Japan after the Fukushima accident has been investigated mainly for volatile fission products, but only sparsely for actinides such as plutonium. Only small releases of actinides were estimated in Fukushima. Plutonium is still omnipresent in the environment from previous atmospheric nuclear weapons tests. We investigated soil and plants sampled at different hot spots in Japan, searching for reactor-borne plutonium using its isotopic ratio Pu-240/Pu-239. By using accelerator mass spectrometry, we clearly demonstrated the release of Pu from the Fukushima Daiichi power plant: While most samples contained only the radionuclide signature of fallout plutonium, there is at least one vegetation sample whose isotope ratio (0.381 +/- 0.046) evidences that the Pu originates from a nuclear reactor (Pu239+240 activity concentration 0.49 Bq/kg). Plutonium content and isotope ratios differ considerably even for very close sampling locations, e.g. the soil and the plants growing on it. This strong localization indicates a particulate Pu release, which is of high radiological risk if incorporated.CDC NIOSH Mountain and Plains Education and Research Center/T42OH009229-07NRC/NRC-HQ-12-G-38-0044CDC NIOSH Mountain and Plains Education and Research Center/T42OH009229-07NRC/NRC-HQ-12-G-38-004

Exhaled breath condensate acidification in acute lung injury

AbstractLung injury in ventilated lungs may occur due to local or systemic disease and is usually caused by or accompanied by inflammatory processes. Recently, acidification of exhaled breath condensate pH (EBC-pH) has been suggested as marker of inflammation in airway disease. We investigated pH, ammonia, lactate, pCO2, HCO3−, IL-6 and IL-8 in EBC of 35 ventilated patients (AECC-classification: ARDS: 15, ALI: 12, no lung injury: 8).EBC-pH was decreased in ventilated patients compared to volunteers (5.85±0.32 vs. 7.46±0.48; P<0.0001). NH4+, lactate, HCO3−, pCO2, IL-6 and IL-8 were analyzed in EBC and correlated with EBC-pH. We observed correlations of EBC-pH with markers of local (EBC IL-6: r=−0.71, P<0.0001, EBC IL-8: r=−0.68, P<0.0001) but not of systemic inflammation (serum IL-6, serum IL-8) and with indices of severity of lung injury (Murray's Lung Injury Severity Score; r=−0.73, P<0.0001, paO2/FiO2; r=0.54, P<0.001). Among factors potentially contributing to pH of EBC, EBC-lactate and EBC-NH4+ were found to correlate with EBC-pH.Inflammation-induced disturbances of regulatory mechanisms, such as glutaminase systems may result in EBC acidification. EBC-pH is suggested to represent a marker of acute lung injury caused by or accompanied by pulmonary inflammation

Spectroscopija 125Te (n,γ), (d,p) i (3He,α) reakcijama

Single γ-ray spectra and γγ-coincidences, following thermal neutron capture in 124Te, were measured with semiconductor detectors at the light-water reactor LWR - 15 at Řež. Intensities of g transitions in 125Te were normalized using the absolute intensity of 7.8% of the 6620 keV line in 36Cl. The high resolution (d,p) measurements were performed with 17 MeV deuterons, using the Q3D spectrograph at two scattering angles of 15° and 30°. Spectra were recorded in the range up to 3.3 MeV and calibrated using the proton peaks with l =1, and the corresponding level energies were determined in the thermal neutron capture reaction. The (3He,α) experiment was carried out with a 32 MeV He beam at the angle of 10°. The spectrum was recorded in one run by means of a large detector in a range up to approximately 4.7 MeV. The absolute intensities were determined by measuring the total beam current.Mjerili su se izravni γ- i sudesni γ-γ-spektri nakon uhvata termičkih neutrona u 124Te. Mjerenja (d,p) reakcija visokog razlučivanja na toj jezgri izvela su se s deuteronima 17 MeV na kutovima od 15° i 30° , pomoću Q3D spektrografa. Također se mjerio spektar u reakciji (3He,α) na 10° . Na osnovi tih mjerenja utvrđena su mnoga nova stanja 125Te na energijama uzbude do oko 4.5 MeV. Razlika grananja 403/443 keV iz izravnih i sudesnih γ-spektara ukazuje na jaku primjesu E2 u primarnom prijelazu od 6125 keV
