Temperature stresses in cylindrical ignot at heating in circular furnaces

There is received for the first time solution of the problem of nonlinear thermomechanics (heat conduction and thermoelasticity) for the case of heating of cylinder ingots in the counter-current regime. Analysis of the received solution allowed to establish more low level of thermo-stressed state of ingots in contra-flow as compared with direct-flow

Analysis of temperature state of massive flat ingot in conditions of radiational contraflow

There is given the analysis of the task solution of counterflow heat exchange at heating of solids of classic form taking into account non-linearities of I and II type. As a mathematical apparatus there is used “the method of equivalent sources of energy”

Transverse momentum spectra of charged particles in proton–proton collisions at √s=900 GeV with ALICE at the LHC

The inclusive charged particle transverse momentum distribution is measured in proton–proton collisions at s=900 GeV at the LHC using the ALICE detector. The measurement is performed in the central pseudorapidity region (|η|<0.8) over the transverse momentum range 0.15<pT<10 GeV/c. The correlation between transverse momentum and particle multiplicity is also studied. Results are presented for inelastic (INEL) and non-single-diffractive (NSD) events. The average transverse momentum for |η|<0.8 is 〈pT〉INEL=0.483±0.001 (stat.)±0.007 (syst.) GeV/c and 〈pT〉NSD=0.489±0.001 (stat.)±0.007 (syst.) GeV/c, respectively. The data exhibit a slightly larger 〈pT〉 than measurements in wider pseudorapidity intervals. The results are compared to simulations with the Monte Carlo event generators PYTHIA and PHOJET
