Abstract: We describe a cooperative measurement of the capture rate of solar neutrinos by the reaction 71Ga(ν e,e−)71Ge. Extractions were made from a portion of the gallium target in the Russian–American Gallium Experiment SAGE and the extraction samples were transported to the Gran Sasso laboratory for synthesis and counting at the Gallium Neutrino Observatory (GNO). Six extractions of this type were made and the resultant solar neutrino capture rate was SNU, which agrees well with the overall result of the gallium experiments. The major purpose of this experiment was to make it possible for SAGE to continue their regular schedule of monthly solar neutrino extractions without interruption while a separate experiment was underway to measure the response of 71Ga to neutrinos from an 37Ar source. As side benefits, this experiment proved the feasibility of long-distance sample transport in ultralow background radiochemical experiments and familiarized each group with the methods and techniques of the other.

Abstract: We report the complete GNO solar neutrino results for the measuring periods GNO III, GNO II, and GNO I. The result for GNO III (last 15 solar runs) is or (1σ) with errors combined. The GNO experiment is now terminated after altogether 58 solar exposure runs that were performed between 20 May 1998 and 9 April 2003. The combined result for GNO (I+II+III) is (1σ) or (1σ) with errors combined in quadrature. Overall, gallium based solar observations at LNGS (first in GALLEX, later in GNO) lasted from 14 May 1991 through 9 April 2003. The joint result from 123 runs in GNO and GALLEX is (1σ). The distribution of the individual run results is consistent with the hypothesis of a neutrino flux that is constant in time. Implications from the data in particle- and astrophysics are reiterated.

The Gallium-Neutrino-Experiment at GNO measures solar neutrinos radiochemically via the reaction 71Ga(ν,e)71Ge. In order to reduce statistical and systematic uncertainties in detecting the decay of 71Ge to 71Ga, a favourable way could be the use of high-resolution cryogenic detectors instead of the presently integrated miniaturized proportional counters. After the successful development of a highly efficient 4π-detector, optimization of thermal Ge-deposition and decoupling of deposition and detection, present activity concentrates on low background considerations, enhancement of external and internal shielding of the cryostat and a long-term run with artificially activated 71Ge to prove the feasibility of ‘cryoGNO’ in our Underground Laboratory in Garching.

We report the first GNO solar neutrino results for the measuring period GNOI, solar exposure time May 20, 1998 till January 12, 2000. In the present analysis, counting results for solar runs SR1 - SR19 were used till April 4, 2000. With counting completed for all but the last 3 runs (SR17 - SR19), the GNO I result is [65.8 +10.2 -9.6 (stat.) +3.4 -3.6 (syst.)]SNU (1sigma) or [65.8 + 10.7 -10.2 (incl. syst.)]SNU (1sigma) with errors combined. This may be compared to the result for Gallex(I-IV), which is [77.5 +7.6 -7.8 (incl. syst.)] SNU (1sigma). A combined result from both GNOI and Gallex(I-IV) together is [74.1 + 6.7 -6.8 (incl. syst.)] SNU (1sigma)., submitted to Physics Letters B, June 2000. PACS: 26.65. +t ; 14.60 Pq.

Estimation of magnitude and frequency of extreme rainfall has immense importance to make decisions about hydraulic structures like spillways, dikes and dams etc. This research involves the estimation of regional rainfall quantiles of 23 sites using L-moment based index flood regional frequency analysis. Initially, different tests are applied to check the assumptions of independence, stationarity and identical distribution. An L-moment based discordancy measure is used to detect discordant sites. Since in Pakistan, highly elevated area receive more rainfall. On the basis of this characteristic, the study region is divided into three regions which satisfy the L-moment based heterogeneity statistics using Monte Carlo simulations from Kappa distribution. The regional quantile estimates are obtained from GEV, GNO and GLO distributions which are found to be best choices for all three regions based on L-moment ratio diagram, Z-Statistics and average weighted difference values. For robust regional estimates, some accuracy measures are calculated using a simulation study of regional L-moment algorithm. On the basis of relative bias, relative absolute bias and relative RMSE, GNO is found be best robust for regional quantile estimation at lager return periods of 50, 100, 500 and 1000 and GEV at return periods of 1, 2, 5, 10 and 20 for all three regions.

Die radiochemischen Gallium-Experimente GALLEX/GNO und SAGE haben zur Lösung des solaren Neutrinoproblems und der Entdeckung von Neutrino-Oszillationen wesentlich beigetragen. Mit dem Einsatz eines neuen hocheffizienten Detektorkonzepts, das auf Tieftemperaturdetektoren beruht, kann das Potential der Experimente weiter erheblich verbessert werden. Im Rahmen dieser Arbeit wurden die Daten dieser Experimente weiter analysiert und mit dem neuen Detektorkonzept Messungen durchgeführt, u.a. eine Langzeitmessung des 71Ge-Zerfalls. Die neue, hocheffiziente Nachweistechnik für niederenergetische Röntgen-Strahlung kann auch in einer Vielzahl weiterer Aktivitätsanalysen Anwendung finden. The radiochemical Gallium experiments GALLEX/GNO and SAGE have contributed considerably to the solution of the solar neutrino problem and the discovery of neutrino oscillations. Using a new, highly efficient detector concept based on low temperature detectors, the potential of the experiments can be improved substantially. In this work, the data analysis of the experiments was continued and measurements using the new detector concept were performed, e.g. a long-term measurement of the decay of 71Ge. The new, highly efficient detection method for low-energy X-rays is applicable in a variety of different activity analyses.

- Abstract
Objective: Cardiac surgery requiring cardiopulmonary bypass and cardioplegic arrest leads to myocardial ischemic and reperfusion injury. Gaseous nitric oxide has been demonstrated to have a myocardial protective effect following ischemia-reperfusion. We hypothesized that gaseous nitric oxide administered during cardiopulmonary bypass would have similar beneficial effects., Methods: In a prospective, randomized, blinded, placebo-controlled study, children undergoing repair of tetralogy of Fallot received either 20 ppm of gaseous nitric oxide or placebo delivered to the membrane oxygenator during cardiopulmonary bypass., Results: A total of 16 children were randomized into 2 equal groups once their parents or guardians had given written informed consent. No differences were found in age, crossclamp time, cardiopulmonary bypass time, or methemoglobin between the 2 groups. The group receiving gaseous nitric oxide had a significantly shortened duration of mechanical ventilation (8.4 ± 7.6 vs 16.3 ± 6.5 hours; P < .05) and intensive care unit length of stay (53.8 ± 19.7 vs 79.4 ± 37.7 hours; P < .05) compared with the placebo group. The patients had significantly lower troponin levels at 12, 24, and 48 hours (P < .05) and lower B-type natriuretic peptide levels at 12 and 24 hours (P < .05). A trend was found toward a less positive fluid balance, with significantly less diuretic usage. The study patients had a greater mean hemoglobin at 48 hours, despite the absence of differences in chest tube output, packed red blood cell transfusion, platelet counts or transfusion requirements, fresh frozen plasma transfusion, or prothrombin time/partial thromboplastin time in the first 48 hours., Conclusions: The delivery of gaseous nitric oxide to the cardiopulmonary bypass circuit for children undergoing cardiac surgery results in myocardial protection, improved fluid balance, and an improved postoperative intensive care unit course., (Copyright © 2013 The American Association for Thoracic Surgery.
