 Analysis of electron – positron annihilation into hadrons in the range of energies above 60 GeV shows that apart from two jet events, there are evidence for three jet events that according to the QCD theory interpreted as a gluon radiation by a quark. However, the higher order diagrams lead to four jet events. In this paper, we study the fragmentation of quarks and gluons into hadronic jets . ...

We employ a recently proposed model [Murisic et. al, JFM 2013] to study a finite-volume, particle-laden thin film flowing under gravity on an incline. For negatively buoyant particles with concentration above a critical value, the similarity solution is of the rarefaction-singular shock type. We investigate the structure in detail and find that the particle/fluid front advances linearly to the ...

A numerical model of initial dilution of sewage emerging from an orifice of a diffuser into stratified waters of the southern part of the Gulf of Trieste is presented. Municipial wastewater from the town of Piran empties into the sea from two diffusers at the end of adjacent submarine pipes (length 3.5 km), located at the open entrance of the shallow Bay of Piran (depth 21 m). First a numerical...

an experimental study has been performed to investigate the flow physics of an under-expanded axisymmetric supersonic jet exhausting transversely from a flat plate into a subsonic compressible cross flow. the goal was to study the effects of boundary layer thickness ratio (δ/d) and the jet to free stream dynamic pressure ratio (j) on surface pressure. the resulting measurements distinctly show ...

Different variants for buoyancy-affected terms in k-ε turbulence model have been utilized to predict the flow parameters more accurately, and investigate applicability of alternative k-ε turbulence buoyant closures in numerical simulation of a horizontal gravity current. The additional non-isotropic turbulent stress due to buoyancy has been considered in production term, based on Algebraic Stre...

Mitochondria from avocado (Persea americana Mill, var. Fuerte and Hass) can be rapidly prepared at every stage of ripening using differential centrifugation and self-generated Percoll gradients. The procedure results in improved oxidative and phosphorylative properties, especially for mitochondria isolated from preclimacteric fruits.A gradual change in the buoyant density of avocado mitochondri...
