To assess whether antithrombotic prophylaxis with low-molecular-weight heparin effectively prevents recurrence of late pregnancy complications, 135 women with previous history of preeclampsia, hemolytic anemia, elevated liver enzymes and low platelet count syndrome, intrauterine fetal death, fetal growth restriction, or placental abruption who had been(More)
Three jet events arising from decays of the Z bo-son, collected by the DELPHI detector, were used to measure differences in quark and gluon fragmentation. Gluon jets were anti-tagged by identifying b quark jets. Unbiased quark jets came from events with two jets plus one photon. Quark and gluon jet properties in different energy ranges were compared for the(More)
OBJECTIVE To test the hypothesis that reduced birth weight in normal fetuses born at moderately high altitude (Denver), compared with the birth weight in normal fetuses born at sea level (Milan), is caused by a reduction in both lean mass and subcutaneous fat mass. STUDY DESIGN Ninety-four normal singleton pregnancies (46 in Denver, 48 in Milan) had(More)
The TOTEM collaboration has developed and tested the first prototype of its Roman Pots to be operated in the LHC. TOTEM Roman Pots contain stacks of silicon detectors with strips oriented in two orthogonal directions. To measure proton scattering angles of a few microradians, the detectors will approach the beam centre to a distance of 10 σ + 0.5 mm (= 1.3(More)
A prototype of the barrel Tracking Detector of the Compact Muon Solenoid (CMS) experiment proposed for LHC was built and tested in a beam and in a magnetic eld of up to 3 T. It contained 6 microstrip gas chambers, 25 cm long, and 3 double-sided silicon microstrip detectors, 12.5 cm long. We report some preliminary results on the performance of the chambers.
Chronic lymphocytic leukaemia (CLL) is the most common leukaemia in the Western world. Despite this fact, its coexistence with pregnancy is extremely rare, with few cases reported in the literature. Given the rarity of this event, it is difficult to conduct large prospective trials to evaluate diagnostic, management, and outcome aspects. The existing(More)
TOTEM has measured the differential cross-section for elastic proton-proton scattering at the LHC energy of √ s = 7 TeV analysing data from runs with a standard β * = 1.5m optics. The differential cross section is measured over a |t|-range from 0.36 to 2.5 GeV 2. The differential cross-section shows a significant diffractive minimum at |t| = (0.53 ± 0.01(More)
In an analysis of multihadronic events recorded at LEP by DELPHI in the years 1992 through 1994, charged hadrons are identiied using the measurement of their energy loss and their Cherenkov angle. Rapidity correlations of-, proton-proton, and-proton pairs are compared. The agreement with the string and cluster fragmentation models is tested. For those pairs(More)
