We present new results on production of He and t obtained by the NA49 experiment in 20A, 30A, 40A and 80A GeV central Pb+Pb collisions at the CERN SPS. Transverse mass spectra and rapidity distributions for clusters measured over a large phase space domain are discussed. We observe a weak dependence of the mid-rapidity t/He ratio on collision energy at SPS. The energy dependence of the total yi...

We present a detailed study of chemical freeze-out in p-p, C-C, Si-Si and Pb-Pb collisions at beam momenta of 158A GeV as well as Pb-Pb collisions at beam momenta of 20A, 30A, 40A and 80A GeV. By analyzing hadronic multiplicities within the statistical hadronization model, we have studied the parameters of the source as a function of the number of the participating nucleons and the beam energy....

Angular correlations of high-pT hadrons can serve as a probe of interactions of partons with the dense medium produced in high-energy heavy-ion collisions but other sources of such correlations exist which can be non-negligible SPS energies. In an attempt to determine the primary source, NA49 has performed an energy and system-size scan of two-particle azimuthal correlations in central Pb+Pb, S...

the high temperature oxidation behaviour of nimonic-115 industrial alloy has been investigated in presence of  nano3, na2co3 and na2o2 at 850oc in flowing air. the oxidation kinetics and effect of salt deposition for the period of 48 h were studied. the scale morphologies were determined on the basis of x-ray diffraction analysis and scanning electron microscopic techniques. it has been shown t...

This experimental work attempts to determine the surface temperature evolution of large (20 Ah-rated capacity) commercial Lithium-Ion pouch cells for the application of rechargeable energy storage of plug in hybrid electric vehicles and electric vehicles. The cathode of the cells is nickel, manganese and cobalt (NMC) based and the anode is graphite based. In order to measure the surface tempera...

Nowadays, advanced turning processes are extensively being adopted to perform different types of operations such as straight turning, taper on Hastelloy, Nimonic, and Inconel, stainless steel, tool steel fabricate better quality cylindrical rotating parts miniature-bars, miniature-pins, miniature-electrodes, miniature-tools. This paper presents a review the previous research conducted miniature...

It is shown that the inclusion of hadronic interactions, and in particular nuclear potentials, simulations heavy ion collisions at SPS energy range can lead to obvious correlations protons. These contribute significantly an intermittency analysis as performed NA61 experiment. The beam system size dependence studied by comparing resulting index for different nuclei energies 40A, 80A 150A GeV. fr...
