In this study, the crystallization behavior of melt-spun Al87Ni10La3 amorphous phase was investigated by using X-ray diffraction and non-isothermal differential thermal analysis techniques. The results demonstrated that the amorphous phase exhibited two-stage crystallization on heating, i.e., at first step the amorphous phase transforms into α-Al phase and at second step Al11La3 and Al3Ni inter...

The BABAR detector, which operates at the SLAC PEP-II asymmetric e+e− collider at energies near the Υ (4S) resonance, started operation on the 26 of May 1999. We present the first study of sin2β, with samples of B → J/ψK S and B → ψ(2S)K S decays, using 9.0 fb−1 of data recorded between January and July 2000 at the Υ (4S) resonance and 0.8 fb−1 recorded 40 MeV below the Υ (4S) resonance. A prel...

this paper aims at studying a trigeneration system, based on an internal combustion engine and a steam ejector refrigeration system. the designed cycle is to generate cooling and heating energies, and supply power simultaneously. the cycle is studied from thermodynamics point of view and for this purpose, the first law of thermodynamics is applied to all components of the cycle. the efficiency ...

background: t-2 mycotoxin belongs to the trichothecene family and has damaging effects on the immune system. objective: to investigate the toxic effect of t-2 toxin on the percentage of peripheral blood b lymphocytes and the potential protective role of selenium and vitamin e. method: frequencies of b lymphocytes (cd19+ ) were analyzed after injection of sublethal doses of t-2 toxin into balb/c...
