We report on measurements of quantum electrodynamic processes in an intense electromagnetic wave, where nonlinear e ects (both multiphoton and vacuum polarization) are prominent. Nonlinear Compton scattering and electronpositron pair production have been observed in collisions of 46.6 GeV and 49.1 GeV electrons of the Final Focus Test Beam at SLAC with terawatt pulses of 1053 nm and 527 nm wave...

the environmental scanning electron microscopy (esem) is a new development in the field of electron microscopy. in this study esem has been used to study the structure of veal semimembranosus muscle. four treatments, raw (control), conventional heating, domestic and industrial microwave heating, were observed using esem. the temperature used in conventional heating was 163 0c. frequency app...

OF ORGANOGERMANIUM AND ORGANOTIN DERIVATIVES OF HYDROXAMIC ACIDS Valery S. Petrosyan*, Natalia S. Yashina, and Sergei V. Ponomarev Department of Chemistry, M. V. Lomonosov University, Moscow 119899, Russia Hydroxamic acids as the precursors oftheir organogermanium and organotin derivatives have been themselves intensively studied fi’om the viewpoint of their potential biological activities [1-3...

Lemma 23. ∀ T ∈ N, x̄ = (x0, x1, . . . , xT ) ∈ R, ∃ hx̄,T ∈ H such that (x0, x1, . . . , xT , 0, 0, . . .) ∈ C∗ hx̄,T+1 . Proof. For arbitrary h, define c by c0 = x0+φ(h), c h t = xt+φ(hc h 0c h 1 · · · ct−1) for all 1 ≤ t ≤ T , and ct = φ(hc0c1 · · · ct−1) for t > T . φ is strictly increasing, so we may choose hx̄,T ∈ H sufficiently large so that (c hx̄,T 0 , c hx̄,T 1 , . . . c hx̄,T T ) is nonnega...

Multicomponent and high-boron cast alloys have been recognized as materials with excellent wear resistance due to the formation of hard phases called carbides borides. However, performance combination these two hybrid multicomponent (HMCAs) has not comprehensively studied. Therefore, this study will evaluate effect C (0–0.9 wt.%) B (1.5–3.5 addition on erosion behavior an HMCA containing 2.5 wt...

This paper revealed the variations observed in daily air temperature Makurdi Metropolis, Benue State, Nigeria. The data used here is a 37years (1984-2021) on sourced from National Aeronautics and Space Administration (NASA). Two way Analysis of Variance (ANOVA) model was results that both months, years interaction were all significance (0.000 < 0.05). means metropolis are statistically acros...
