HIsarna is a novel ironmaking process with great raw materials versatility that attractive for various secondary resources. Among the can be recycled, there steel scrap which fed to furnace bath through an inclined chute. The velocity distribution of particles along chute affects particles’ on liquid slag and, thereupon, efficient operation reactor. In this study, flow same dimensions as those ...

In this contribution we summarize experimental information and theoretical results for the dissociation cross sections of charmonium by light hadrons. Theoretical predictions for these RHIC-related processes differ by orders of magnitude over the physically relevant energy range. The results found by the author and collaborators using a constituent interchange model, which predicts cross sectio...

Precision measurements at LEPII provide a unique test of Standard Model predictions. Results from the four LEP collaborations ALEPH, DELPHI, L3 and OPAL on the difermion cross-sections and asymmetries obtained at centre-of-mass energies between 192 and 202 GeV are presented. The high s ′ results are used to determine the running of the electromagnetic coupling constant and the strength of the i...

The UV-visible absorption spectrum of gaseous IONO 2 has been measured over the wavelength range 245–415 nm using the technique of laser photolysis with time-resolved UV-visible absorption spectroscopy. IONO 2 was produced in situ in the gas phase by laser flash photolysis of NO 2 /CF 3 I/N 2 mixtures. Post-flash spectra were deconvolved 5 to remove contributions to the observed absorption from...

The status of W and Z cross-section and width measurements from the CDF and D0 experiments is reviewed. Recent results that are discussed: the cross-section for Z production times the branching ratio to tau pairs, the rapidity and transverse momentum distributions of Z production in the electron channel, and the direct measurements of the W width and the Z invisible width; the latter from an an...

Diameter and Stability When a tree is impacted by a wind force, its cells in the trunk on the windward (wind-exposed) side are stretched, while those on the leeward (wind-sheltered) side are compressed (Figure 1). Furthermore, the tree crown’s own weight has to be added as well, which results in an even higher compression load on the leeward cells and a correspondingly lower tension on the oppo...

The pier scour process is normally intensified in the presence of an ice cover, which poses risks to longevity and safety bridges. In present study, impact densimetric Froude number, locations, spacing side-by-side piers on local depth under ice-covered flow conditions were investigated based clear water experiments S-shaped laboratory flume. results demonstrated that at along convex bank was m...

AIM To analyse the gutta-percha filled area of C-shaped molar teeth root filled with the modified MicroSeal technique with reference to the radiographic features and the C-shaped canal configuration. METHODOLOGY Twenty-three mandibular second molar teeth with C-shaped roots were classified according to their radiographic features as: type I--merging, type II--symmetrical and type III--asymmet...

In ee and in hadron-hadron reactions at collider energies, prompt photons are observed and their cross sections are measured only if the photons are relatively isolated in phase space. Isolation is required to reduce various hadronic backgrounds including those from the electromagnetic decay of mesons, e.g., π → 2γ. The essence of isolation is that a cone of half-angle δ is drawn about the dire...
