Precise mapping of the magnetic field in the CMS barrel yoke using cosmic rays
This is the Pre-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2010 IOPThe CMS detector is designed around a large 4 T superconducting solenoid, enclosed in a 12 000-tonne steel return yoke. A detailed map of the magnetic field is required for the accurate simulation and reconstruction of physics events in the CMS detector, not only in the inner tracking region inside the solenoid but also in the large and complex structure of the steel yoke, which is instrumented with muon chambers. Using a large sample of cosmic muon events collected by CMS in 2008, the field in the steel of the barrel yoke has been determined with a precision of 3 to 8% depending on the location.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ,

Female infants are more susceptible to the effects of maternal antenatal depression; Findings from the Pelotas (Brazil) Birth Cohort Study
Background:
We utilised data from the 2015 Pelotas Birth Cohort, a large prospective cohort in southern Brazil, to examine the association of moderate and severe antenatal depression with child birth outcomes and explore interactions with sociodemographic characteristics.
Methods:
Data was available for n = 3046 participants and their infants. We measured antenatal depression using the Edinburgh Postnatal Depression Scale (EPDS, âĽ13 for moderate and âĽ17 for severe depression). Outcome measures included gestational age, birth weight, length and head circumference, using the Intergrowth-21st standards. We controlled for known confounders including obstetric risk.
Results:
We did not find differences in childbirth outcomes by maternal depression status for participants with at least moderate depression, although there was an increased risk for female offspring to be small for gestational age (SGA, OR 2.33[1.37,3.97]). For severe depression (EPDSâĽ17) we found an increased risk for lower APGAR scores (OR 1.63[1.02,2.60]) and being SGA (OR 1.77[1.06,2.97], with an increased risk for female offspring in particular to be in lower weight centiles (â10.71 [â16.83,â4.60]), to be SGA (OR 3.74[1.89, 7.44]) and in the lower 10th centile for length (OR 2.19[1.25,3.84]).
Limitations:
include the use of a maternal report questionnaire to ascertain depressive symptoms.
Conclusions:
In this recent large longitudinal cohort in Brazil we did not find independent effects of depression on adverse birth outcomes or interactions with sociodemographic characteristics. We found an increased risk of being SGA for female offspring of women with moderate and severe depression, in line with other research suggesting females may be more susceptible to antenatal disturbances.</p
Mothers and their pregnancies: a comparison of three population-based cohorts in Southern Brazil Mães e suas gestaçþes: uma comparação de três coortes de base populacional no Sul do Brasil
Mothers from the 1982, 1993 and 2004 Pelotas birth cohorts were compared across biological, socioeconomic, demographic and reproductive characteristics. Women in the 2004 cohort had higher levels of education, gained more weight during pregnancy, and were heavier at the beginning and end of their pregnancy than mothers who gave birth in 1993 and 1982. There was an important increase in obesity rates (body mass index > 30kg/m²) over the 22 years of the study. Mean parity decreased from 1.3 in 1982 to 1.1 in 2004, with a growing proportion of primiparas and a decline in the proportion of women with > 4 children. The mean birth interval increased from 33.5 months in 1982 to 65.7 in 2004. Smoking during pregnancy decreased from 35.6% in 1982 to 25.1% in 2004. As with other characteristics, the change in smoking status differed according to income, with higher reductions among the wealthiest (from 24.9% to 8.7%) than among the poorest mothers (from 43.7% to 33.6%). In general terms, between 1993 and 2004 there was a decrease in the prevalence of maternal risk factors for unfavorable perinatal outcomes.<br>As mĂŁes das coortes de nascimentos de Pelotas de 1982, 1993 e 2004 foram comparadas em relação a caracterĂsticas biolĂłgicas, sĂłcio-econĂ´micas, demogrĂĄficas e reprodutivas. As mĂŁes da coorte de 2004 tinham escolaridade mais alta, ganharam mais peso durante a gestação e pesavam mais no inĂcio e final da gestação, comparadas com as mĂŁes de 1993 e 1982. Houve um aumento importante nas taxas de obesidade (Ăndice de massa corporal >30kg/m²) ao longo dos 22 anos do estudo. A paridade mĂŠdia diminuiu de 1,3 em 1982 para 1,1 in 2004, com um aumento na proporção de mulheres primĂparas e um declĂnio na proporção de mulheres com > 4 crianças. O intervalo mĂŠdio entre nascimentos aumentou de 33,5 meses em 1982 para 65,7 em 2004. O hĂĄbito de fumar durante a gravidez diminuiu de 35,6% em 1982 para 25,1% m 2004. Assim como outras caracterĂsticas, a mudança no tabagismo mostrou diferenças de acordo com renda familiar, com uma redução menor nas mĂŁes de maior renda (de 24,9% para 8,7%), comparadas com as mais pobres (de 43,7% para 33,6%). Em termos gerais, entre 1993 e 2004 houve uma diminuição na prevalĂŞncia de fatores de risco maternos para desfechos perinatais desfavorĂĄveis
