Indicated biological effect from the 9 July 1962 high altitude nuclear test

An influence of the 9 July 1962 high altitude nuclear test on the reproductive responses in DROSOPHILA cultures was indicated by the occurrence of simultaneous minimas in progeny curves. Progeny from cultures grown in magnetic fields disclosed less deviation from a four generation mean value than did progeny from control cultures. It is suggested that the magnetic fields deflected a portion of the increased 9 July radiation from the test region. Based on limited data,the possibility exists that a protective effect may have been transferred to first generation flies grown out of the magnetic fields. Ein Einfluss des Kernversuchs in grosser Höhe vom 9.Juli 1962 auf die Reaktion von DROSOPHILA-Kulturen wurde durch das Vorkommen gleichzeitiger Minimas in den Kurven für die Nachkommenschaft angedeutet. Die Nachkommen aus Kulturen, die in magnetischen Feldern gewachsen waren, zeigten eine geringere Abweichung vom Mittelwert von 4 Generationen als die Nachkommen aus Vergleichskulturen.Es wird vermutet, dass die magnetischen Felder einen Teil der Strahlung vom 9.Juli vom Versuchsgebiet ablenkten. Es besteht die aufgrund begrenzter Daten gewonnene Möglichkeit,dass eine Schutzwirkung auf die erste Generation von Drosophila übertragen worden ist, die ausserhalb der Magnetfelder aufwuchs. Les essais d'explosion atomique effectués à grande altitude le 9 juillet 1962 ont eu des répercussions sur des élevages de DROSOPHILA. On constante en effet des minimums simultanés dans les courbes de descendance. Les descendants provenant d'élevages placés dans un champ magnétique mentrent,en moyenne de 4 générations, une diminution moins marquée que ceux provenant d'élevages de comparaison. On suppose que les champs magnétiques ont fait dévier une partie des radiations du 9 juillet hors du champ d'essais. En se basant sur ces données fragmentaires, on peut admettre la possibilité d'un effet de protection transmis à la première génération des mouches élevées hors des champs magnétiques.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47838/1/484_2005_Article_BF01426847.pd

Measurement of event-shape observables in Z→ℓ+ℓ− events in pp collisions at √ s=7 TeV with the ATLAS detector at the LHC

Event-shape observables measured using charged particles in inclusive $Z$-boson events are presented, using the electron and muon decay modes of the $Z$ bosons. The measurements are based on an integrated luminosity of $1.1 {\rm fb}^{-1}$ of proton--proton collisions recorded by the ATLAS detector at the LHC at a centre-of-mass energy $\sqrt{s}=7$ TeV. Charged-particle distributions, excluding the lepton--antilepton pair from the $Z$-boson decay, are measured in different ranges of transverse momentum of the $Z$ boson. Distributions include multiplicity, scalar sum of transverse momenta, beam thrust, transverse thrust, spherocity, and $\mathcal{F}$-parameter, which are in particular sensitive to properties of the underlying event at small values of the $Z$-boson transverse momentum. The Sherpa event generator shows larger deviations from the measured observables than Pythia8 and Herwig7. Typically, all three Monte Carlo generators provide predictions that are in better agreement with the data at high $Z$-boson transverse momenta than at low $Z$-boson transverse momenta and for the observables that are less sensitive to the number of charged particles in the event.Comment: 36 pages plus author list + cover page (54 pages total), 14 figures, 4 tables, submitted to EPJC, All figures including auxiliary figures are available at http://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/STDM-2014-0
