    Full text link
    The Resistive Plate Chambers detector system at the CMS experiment at the LHC provides robustness and redundancy to the muon trigger. A total of 1056 double-gap chambers cover the pseudo-rapidity region < 1.6. The main detector parameters and environmental conditions are constantly and closely monitored to achieve operational stability and high quality data in the harsh conditions of the second run period of the LHC with center-of-mass energy of 13 TeV. First results of overall detector stability with 2015 data and comparisons with data from the LHC RUN-1 period at 8 TeV are presented

    IMPACT OF BIG FIVE PERSONALITY TRAITS ON JOB PERFORMANCE (ORGANIZATIONAL COMMITMENT AS A MEDIATOR)

    Abstract: This study examines the mediating role of multidimensional organizational commitment concept in determining the relationship between Big Five personality traits and job performance. A conceptual framework has been developed with multidimensional organizational commitment as a mediating variable linking the personality-performance relationship. It is hypothesized that affective commitment will mediate the relationship between extraversion and job performance. Affective commitment will also mediate the relationship between conscientiousness and job performance. It is also hypothesized that continuance commitment will mediated the relationship between neuroticism and job performance. Theoretical implications are discussed

    This study was performed to evaluate and characterize 24 sorghum accessions for various morphological and fodder yield parameters. The germplasm displayed considerable variability for leaf color, midrib color, panicle shape, days to 50% flowering, leaf area, flag leaf area, plant height and green fodder yield, while differences of smaller magnitude were observed for number of leaves and tillers plant-1. Genotype Fsd -sorghum was mature early with minimum days to maturity (63) while maximum plant height (232 cm) was observed for Acc.1692. Moreover, Acc.1827 exhibited maximum leaf area (447 cm2) and the highest green fodder yield at 50% maturity (58 t ha-1) was recorded for Acc. 1763. The results of this study indicate that significant genetic diversity exists among the sorghum accessions. The genetic potential of Fsd-sorghum, accessions 1692, 1827 and 1763 can be exploited in future sorghum breeding programs. Further, these genotypes are recommended for commercial cultivation to meet the fodder needs of the country.Keywords: Fodder, Sorghum bicolor, accession

    Genotypic variation for yield and morphological traits in

    ABSTRACT Genetic variability is the main basis of improvement in crops. An experiment comprising fifteen old and new wheat varieties was planted in randomized complete block design with three replications at the Agricultural Research Farm of NWFP Agricultural University, Peshawar during crop season, 2003-2004. Data were recorded on yield and some other morphological traits. Statistical analysis of the data was carried out and means were separated using the least significance difference test. Correlation coefficients were also determined. Analysis of variance revealed that the varieties differed significantly for days to 50% heading, days to 50% anthesis, plant height and grain yield ha -1 . However, differences were non-significant for physiological maturity, biological yield and harvest index. Days to 50% anthesis showed significantly positive correlations with days to 50% heading, days to maturity and grain yield. Grain yield also exhibited significantly positive correlation with biological yield

    Severe early onset preeclampsia: short and long term clinical, psychosocial and biochemical aspects

    Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks gestational age. It occurs in approximately 3-5% of pregnancies and it is still a major cause of both foetal and maternal morbidity and mortality worldwide1. As extensive research has not yet elucidated the aetiology of preeclampsia, there are no rational preventive or therapeutic interventions available. The only rational treatment is delivery, which benefits the mother but is not in the interest of the foetus, if remote from term. Early onset preeclampsia (<32 weeks’ gestational age) occurs in less than 1% of pregnancies. It is, however often associated with maternal morbidity as the risk of progression to severe maternal disease is inversely related with gestational age at onset2. Resulting prematurity is therefore the main cause of neonatal mortality and morbidity in patients with severe preeclampsia3. Although the discussion is ongoing, perinatal survival is suggested to be increased in patients with preterm preeclampsia by expectant, non-interventional management. This temporising treatment option to lengthen pregnancy includes the use of antihypertensive medication to control hypertension, magnesium sulphate to prevent eclampsia and corticosteroids to enhance foetal lung maturity4. With optimal maternal haemodynamic status and reassuring foetal condition this results on average in an extension of 2 weeks. Prolongation of these pregnancies is a great challenge for clinicians to balance between potential maternal risks on one the eve hand and possible foetal benefits on the other. Clinical controversies regarding prolongation of preterm preeclamptic pregnancies still exist – also taking into account that preeclampsia is the leading cause of maternal mortality in the Netherlands5 - a debate which is even more pronounced in very preterm pregnancies with questionable foetal viability6-9. Do maternal risks of prolongation of these very early pregnancies outweigh the chances of neonatal survival? Counselling of women with very early onset preeclampsia not only comprises of knowledge of the outcome of those particular pregnancies, but also knowledge of outcomes of future pregnancies of these women is of major clinical importance. This thesis opens with a review of the literature on identifiable risk factors of preeclampsia

    Four-lepton production in proton-proton collisions, pp -> (Z/gamma*)(Z/gamma*) -> 4l, where l = e or mu, is studied at a center-of-mass energy of 13 TeV with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb(-1). The ZZ production cross section, sigma(pp -> ZZ) = 17.2 +/- 0.5 (stat) +/- 0.7 (syst) +/- 0.4 (theo) +/- 0.4 (lumi) pb, measured using events with two opposite-sign, same-flavor lepton pairs produced in the mass region 60 4l) = 4.83(-0.22)(+0.23) (stat)(-0.29)(+0.32) (syst) +/- 0.08 (theo) +/- 0.12(lumi) x 10(-6) for events with a four-lepton invariant mass in the range 80 4GeV for all opposite-sign, same-flavor lepton pairs. The results agree with standard model predictions. The invariant mass distribution of the four-lepton system is used to set limits on anomalous ZZZ and ZZ. couplings at 95% confidence level: -0.0012 < f(4)(Z) < 0.0010, -0.0010 < f(5)(Z) < 0.0013, -0.0012 < f(4)(gamma) < 0.0013, -0.0012 < f(5)(gamma) < 0.0013

    Electroweak production of two jets in association with a Z boson in proton-proton collisions root s =13 TeV

    A measurement of the electroweak (EW) production of two jets in association with a Z boson in proton-proton collisions at root s = 13 TeV is presented, based on data recorded in 2016 by the CMS experiment at the LHC corresponding to an integrated luminosity of 35.9 fb(-1). The measurement is performed in the lljj final state with l including electrons and muons, and the jets j corresponding to the quarks produced in the hard interaction. The measured cross section in a kinematic region defined by invariant masses m(ll) > 50 GeV, m(jj) > 120 GeV, and transverse momenta P-Tj > 25 GeV is sigma(EW) (lljj) = 534 +/- 20 (stat) fb (syst) fb, in agreement with leading-order standard model predictions. The final state is also used to perform a search for anomalous trilinear gauge couplings. No evidence is found and limits on anomalous trilinear gauge couplings associated with dimension-six operators are given in the framework of an effective field theory. The corresponding 95% confidence level intervals are -2.6 <cwww/Lambda(2) <2.6 TeV-2 and -8.4 <cw/Lambda(2) <10.1 TeV-2. The additional jet activity of events in a signal-enriched region is also studied, and the measurements are in agreement with predictions.Peer reviewe
