Drought tolerance gene pool in developing adaptive varieties of durum wheat identified in study nurseries under the Kazakhstan-Siberian program

Drought during the wheat vegetative period happens often in West Siberia and Kazakhstan condition. For this reason, varieties with adaptation to climatic zones, drought tolerance and high stability have high importance. The breeding efficiency and rates depend on the amount of information on genotypes in every study cycle. The aim of this study was to screen breeding material in Siberian and Kazakhstan research institutes from KASIB nurseries for drought tolerance and to develop a drought tolerant pool. For the evaluation of genotypes, it is necessary to study them in diverse condition. The basic purpose of the present work is to study breading material of durum wheat from KASIB institutions at different ecological sites. In 2000–2015, durum wheat entries in the Kazakhstan-Siberian program were studied. Progress in durum wheat breeding was tested in Russian and Kazakhstan institutes. Entries were screened for drought tolerance, yield and yield stability. They have value for including in hybridization for developing varieties with adaptation to Siberian and Kazakhstan conditions. The following varieties and lines are recommended for breading for drought tolerance: 383-МС, 452-МС, Каrgala 303, Каrgala 447, Каrgalа 24, Каrgala 1515/06, Каrgala 1516/06, Каrgala 69, Каrgala 1538, Каrgalа 1540, Каrgalа 1539, Kargalа 1671, Каrgalа 1411 (Акtubinsk Agricultural Experimental Station), Hordeiforme 91-25-5, Hordeiforme 91-22-2, Jemthujina Sibiri, Hordeiforme 94-94-13, Hordeiforme 98-42-1, Hordeiforme 01-121-3, Hordeiforme 02-156-1 (Siberian Research Agricultural Institute), Аltin schigis, Аltin dala, Line Г1549 (Каrabalyk Experimental Station), Hordeiforme 373, Hordeiforme 627 (Altai Research Agricultural Institute), 17394, 18053, Nauriz-6 (Кazakh Research-Production Center of Agriculture and Plant Growing), Коllektivnaya 2, ТС-15 (Kurgan Research Agricultural Institute), Line 653d-4 (Sаmara Research Agricultural Institute)

Studies of the Response of the Prototype CMS Hadron Calorimeter, Including Magnetic Field Effects, to Pion, Electron, and Muon Beams

We report on the response of a prototype CMS hadron calorimeter module to charged particle beams of pions, muons, and electrons with momenta up to 375 GeV/c. The data were taken at the H2 and H4 beamlines at CERN in 1995 and 1996. The prototype sampling calorimeter used copper absorber plates and scintillator tiles with wavelength shifting fibers for readout. The effects of a magnetic field of up to 3 Tesla on the response of the calorimeter to muons, electrons, and pions are presented, and the effects of an upstream lead tungstate crystal electromagnetic calorimeter on the linearity and energy resolution of the combined calorimetric system to hadrons are evaluated. The results are compared with Monte Carlo simulations and are used to optimize the choice of total absorber depth, sampling frequency, and longitudinal readout segmentation.Comment: 89 pages, 41 figures, to be published in NIM, corresponding author: P de Barbaro, [email protected]

Relative luminosity measurement of the LHC with the ATLAS forward calorimeter

In this paper it is shown that a measurement of the relative luminosity changes at the LHC may be obtained by analysing the currents drawn from the high voltage power supplies of the electromagnetic section of the forward calorimeter of the ATLAS detector. The method was verified with a reproduction of a small section of the ATLAS forward calorimeter using proton beams of known beam energies and variable intensities at the U-70 accelerator at IHEP in Protvino, Russia. The experimental setup and the data taking during a test beam run in April 2008 are described in detail. A comparison of the measured high voltage currents with reference measurements from beam intensity monitors shows a linear dependence on the beam intensity. The non-linearities are measured to be less than 0.5 % combining statistical and systematic uncertainties.Comment: 16 page

ОЦЕНКА РИСКА ОСТАТОЧНОЙ МИОРЕЛАКСАЦИИ ПРИ ЛАПАРОСКОПИЧЕСКИХ ОПЕРАТИВНЫХ ВМЕШАТЕЛЬСТВАХ

The risk degree of the residual curarization was identified for the tracheal extubation under laparoscopic intervention. It is shown by the quantitative neuromuscular monitoring and "total-blind" control under which recovery rate of the neuromuscular conduction and how soon on the operation completion the intensivists perform the tracheal extubation on a routine basis. Выявлена степень риска остаточной кураризации на момент экстубации трахеи при лапароскопических вмешательствах. С помощью количественного нейромышечного мониторинга и «слепого» контроля показано, при какой степени восстановления нервно-мышечной проводимости и через какое время после окончания операции анестезиологи-реаниматологи рутинно производят экстубацию трахеи при лапароскопической холецистэктомии и аппендэктомии

Precise measurement of the top quark mass in the dilepton channel at D0

We measure the top quark mass (mt) in ppbar collisions at a center of mass energy of 1.96 TeV using dilepton ttbar->W+bW-bbar->l+nubl-nubarbbar events, where l denotes an electron, a muon, or a tau that decays leptonically. The data correspond to an integrated luminosity of 5.4 fb-1 collected with the D0 detector at the Fermilab Tevatron Collider. We obtain mt = 174.0 +- 1.8(stat) +- 2.4(syst) GeV, which is in agreement with the current world average mt = 173.3 +- 1.1 GeV. This is currently the most precise measurement of mt in the dilepton channel.Comment: 7 pages, 4 figure

Search for R-parity violating supersymmetry via the LLE couplings lambda_{121}, lambda_{122} or lambda_{133} in ppbar collisions at sqrt(s)=1.96 TeV

A search for gaugino pair production with a trilepton signature in the framework of R-parity violating supersymmetry via the couplings lambda_121, lambda_122, or lambda_133 is presented. The data, corresponding to an integrated luminosity of L~360/pb, were collected from April 2002 to August 2004 with the D0 detector at the Fermilab Tevatron Collider, at a center-of-mass energy of sqrt(s)=1.96 TeV. This analysis considers final states with three charged leptons with the flavor combinations eel, mumul, and eetau (l=e or mu). No evidence for supersymmetry is found and limits at the 95% confidence level are set on the gaugino pair production cross section and lower bounds on the masses of the lightest neutralino and chargino are derived in two supersymmetric models.Comment: 9 pages, 4 figures (fig2 includes 3 subfigures

Search for new fermions ("quirks") at the Fermilab Tevatron Collider

We report results of a search for particles with anomalously high ionization in events with a high transverse energy jet and large missing transverse energy in $2.4$ fb$^{-1}$ of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron $p\bar{p}$ collider. Production of such particles (quirks) is expected in scenarios with extra QCD-like {\it SU(N)} sectors, and this study is the first dedicated search for such signatures. We find no evidence of a signal and set a lower mass limit of 107 ~GeV for the mass of a charged quirk with strong dynamics scale $\Lambda$ in the range from 10 keV to 1 MeV.Comment: submitted to Phys. Rev. Letter

Measurement of the t-channel single top quark production cross section

The D0 collaboration reports direct evidence for electroweak production of single top quarks through the t-channel exchange of a virtual W boson. This is the first analysis to isolate an individual single top quark production channel. We select events containing an isolated electron or muon, missing transverse energy, and two, three or four jets from 2.3 fb^-1 of ppbar collisions at the Fermilab Tevatron Collider. One or two of the jets are identified as containing a b hadron. We combine three multivariate techniques optimized for the t-channel process to measure the t- and s-channel cross sections simultaneously. We measure cross sections of 3.14 +0.94 -0.80 pb for the t-channel and 1.05 +-0.81 pb for the s-channel. The measured t-channel result is found to have a significance of 4.8 standard deviations and is consistent with the standard model prediction.Comment: 7 pages, 6 figure

Measurement of trilinear gauge boson couplings from WW + WZ to lnu jj events in pp-bar collisions at sqrt{s}=1.96 TeV

We present a direct measurement of trilinear gauge boson couplings at gammaWW and ZWW vertices in WW and WZ events produced in pp-bar collisions at sqrt{s}=1.96 TeV. We consider events with one electron or muon, missing transverse energy, and at least two jets. The data were collected using the D0 detector and correspond to 1.1/fb of integrated luminosity. Considering two different relations between the couplings at the gammaWW and ZWW vertices, we measure these couplings at 68% C.L. to be kappa_{gamma}=1.07^{+0.26}_{-0.29}, lambda =0.00^{+0.06}_{-0.06} and g_{1}^{Z}=1.04^{+0.09}_{-0.09} in a scenario respecting SU(2)_L x U(1)_Y gauge symmetry and kappa =1.04^{+0.11}_{-0.11} and lambda=0.00^{+0.06}_{-0.06} in an "equal couplings" scenario.Comment: 14 pages, 7 figures, published in Phys.
