In recent years, impinging streams have received increasing interest for their high efficiency in heat and mass transfer. This numerical study was conducted to investigate flow and heat transfer characteristics of one-way opposing jets of non-Newtonian fluids. Effects of Reynolds number impinging angle, momentum ratio and flow behavior index on mixing index were evaluated. The results showed im...

The seesaw mechanism is introduced and some of its different realizations and applications are discussed. It is pointed out how they can be used to understand the bi-large mixing patterns among neutrinos in combination with the assumptions about high scale physics such as grand unification or quasidegeneracy of neutrino masses.

We examine the structure of the quaternion group Q8 and its possible application to the physics of flavor. We find that a Q8 family symmetry is suitable to explain the difference between quark and lepton mixing patterns. Distinctive phenomenological predictions are derived for the neutrino sector and the electroweak Higgs sector. We also show how the Q8 symmetry suppresses the effective operato...

Some of the Adamantane properties were calculated in this study. Chemical shift, free energy ofsolvation, free energy of cavity formation, Henry's law constant, and other properties ofAdamantane in dry phase, three solvents and three temperatures have been calculated with Abinitio method base on density functional theory (DFT) at B3lyp/6-31g, B31yp/6-31g*, B3lyp/6-31+g* and B3lyp/6-31++g** leve...

OBJECTIVES The role of occupational exposures in hairy cell leukaemia was investigated through a multicentre, hospital based, case-control study. This paper analyses the role of exposure to solvents other than benzene in hairy cell leukaemia. METHODS The study included 226 male cases and 425 matched controls, exposure to solvents was evaluated by expert case by case review of the detailed dat...

olive oil extraction methods and technology can affect the quality and quantity of the extracted oil. in this study, qualitative and quantitative parameters were investigated for oil extracted using a hammer crusher at 720 and 1450 rpm at 30°, 40°, 60° c mixing temperatures. the data were analyzed using a complete randomized block factorial design using spss software with three replications. th...

The emission spectra of naphthalene labeled hydrocarbons (NpHCn) and fluorocarbons (NpFCn) and anthracene labeled hydrocarbons (AnHCn) and fluorocarbons (AnFCn) in aqueous organic mixed solvents were investigated. The fluorescence spectrum of NpHC 16 in dimethyl sulfoxide-water (DMSO-H20) is dominated by excimer emission due to formation of aggregates. Addition of a fluorocarbon compound with c...

A mixing rule for the mixtures of hard-spheres is presented which can be reduced to the standard van der Waals mixing rule at low densities. The effectiveness of the mixing rule for the size and energy parameters of lennard-Jones fluid are examined by combining them with an equation of state to calculate thermodynamic properties. The results of calculation are compared with the molecular dy...
