AB  - The cross-section for the production of a single top quark in association with a W boson in proton-proton collisions at √s = 8TeV is measured. The dataset corresponds to an integrated luminosity of 20.3 fb−1, collected by the ATLAS detector in 2012 at the Large Hadron Collider at CERN. Events containing two leptons and one central b-jet are selected. The W t signal is separated from the backgrounds using boosted decision trees, each of which combines a number of discriminating variables into one classifier. Production of W t events is observed with a significance of 7.7σ. The cross-section is extracted in a profile likelihood fit to the classifier output distributions. The W t cross-section, inclusive of decay modes, is measured to be 23.0 ± 1.3(stat.)− 3.5 + 3.2(syst.)±1.1(lumi.) pb. The measured cross-section is used to extract a value for the CKM matrix element |Vtb| of 1.01 ± 0.10 and a lower limit of 0.80 at the 95% confidence level. The cross-section for the production of a top quark and a W boson is also measured in a fiducial acceptance requiring two leptons with pT> 25 GeV and |η| < 2.5, one jet with pT> 20 GeV and |η| < 2.5, and ET miss > 20 GeV, including both W t and top-quark pair events as signal. The measured value of the fiducial cross-section is 0.85 ± 0.01(stat.)− 0.07 + 0.07(syst.)±0.03(lumi.) pb.

AB  - The paper presents the results of indoor radon concentration survey in 201 homes and offices in Niska Banja (the Spa of Nis), a well-known health resort and a spa in the South-East of Serbia. Radon indoor concentrations were determined by active charcoal method, according to standard EPA procedure. The indoor radon concentrations were in the range of up to 200 Bq/m(3) (47%), from 200-600 Bq/m(3) (26%) and over 600 Bq/m(3) (27%). Three areas of extremely high average radon concentrations were found (1340-4340 Bq/m(3)), with a maximum above 13,000 Bq/m(3). The content of natural radionuclides (Ra-226, Ph-214, Bi-214, U-235, Ac-228, Ph-212, Bi-212, (TI)-T-208, K-40) and Cs-117, as well as the content of total uranium, thorium and potassium in mud used in peloidotherapy in the Health Institute Niska Banja was determined, too. The activities of the radionuclides were determined on an HPGe detector, by standard gamma spectroscopy. The results indicated considerably high amounts of total uranium and thorium (0.021 g/kg mud and 0.003 g/kg mud, respectively), due to the karsts origin of the soil. (c) 2006 Elsevier Ltd.

AB  - Be-7 to Pb-210 concentration ratios in ground level air on two monitoring stations (MS1 and MS2) in Belgrade area were determined from 1996 to 2001. The average monthly concentrations of Be-7 in ground level air were in the range of 0.6-18.3 mBq/m(3) and exhibited one or two summer/early fall maxims and one minimum in winter. The maximum concentrations for Pb-210 were generally observed in the fall, with the average concentrations in the range of 1.09 x 10(-4) to 30.9 X 10(-4) Bq/m(3). The Be-7/Pb-210 ratios were in the range of 1.7-12.7 (MS1) and 1.8-11.3 (MS2), with summer maxims and late fall/winter minimums. The mean Radionuclides Loading Indices values approach zero except for 1996/1997 (MS1) and 2001 (MS2) due to higher concentrations of Be-7 and Pb-210. The mean monthly concentrations of both radionuclides exhibited lognormal distributions. There is significant correlation between the Be-7/Pb-210 activities ratio and the air stability classes A+B+C for both monitoring stations (correlation coefficients 0.61-0.65), and no correlation with D class and E+F classes. Correlation was found between the activity of Be-7 and air stability classes A+B+C (0.46-0.68), and E+F (0.38 for MS1), while for Pb-210, a moderate correlation (0.38-0.40) was found with the E+F air stability classes.

AB  - Concentrations of Pb-210 in ground level air in the city area (Belgrade, Central Serbia) were measured in the period from 1985 to 1996. The activity of Pb-210 in air filters was determined on a HPGe detector by standard gamma spectrometry. Total standard error of the method was estimated to be below 25%. The average monthly concentrations of Pb-210 in the ground level air in the period from 1985 to 1996 were in the range of 0.30-3.17 mBq m(-3) with the maxima in fall-winter periods and minimums in springs and early summers. The seasonal indices were 1.12-1.59 for fall-winter and 0.77-0.92 for spring-summer periods. The ratios of maximum-to-minimum concentrations in each year were relatively stable over the period, with slight increase in 1985, 1989 and 1995. The investigations are part of the long-term measurements of natural and man-made radionuclides in the ground-level air in the region. (C) 2000 Elsevier Science Ltd. All rights reserved.

AB  - Concentrations of Be-7 and Cs-137 in ground level air in the city area (Belgrade, central Serbia) were determined in the period from 1991-1996, The average monthly concentrations of Be-7 in ground level air were in the range of 2-7 mBq/m(3) with pronounced one or two maxims in summer or early fall and a minimum in winter; The average air concentrations for Cs-137 were from 0.5-8.5 x 10-5 Bq/m(3), with a spread maximum in the spring-summer period and a pronounced maximum during the winter. A general increase in Be-7 and Cs-137 concentrations during 1993 was recorded. The maximum seasonal indices were 1.3 for Be-7 (summers) and 2.7 (late springs and early summers) and 3,4 (winters) for Cs-137. No correlation with the amount of precipitation and Cs-137 concentrations in air was determined, while the washout effect of rainfalls seems to be more closely related with variations in Be-7 concentrations.
