Uniaxial compressive strength (UCS) and elastic properties of rocks play a major and vital role for the design of any engineering structure. The specimen diameter size is one of the main factors that influencing on UCS, elasticity modulus and Poisson’s ratio (E and υ). Here, an attempt has been made to investigate the effect of specimen diameter size on UCS, E and υ. Moreover, we studied the co...

Monotonicity analysis of delta fractional sums and differences order υ∈(0,1] on the time scale hZ are presented in this study. For analysis, two models discrete calculus, Riemann–Liouville Caputo, considered. There is a relationship between h-difference Caputo h-differences, which we find Therefore, after solve one, can apply same method to other one due their correlation. We show that y(z) υ-i...
We report the study of ee → Υ(1S)ππ, Υ(2S)ππ, Υ(3S)ππ, and Υ(1S)KK, near the peak of the Υ(5S) resonance. The results are based on a data sample of 21.7 fb collected with the Belle detector at the KEKB ee collider. Attributing the signals to the Υ(5S) resonance, the partial widths Γ(Υ(5S) → Υ(1S)ππ) = 0.59± 0.04(stat)± 0.09(syst) MeV and Γ(Υ(5S) → Υ(2S)ππ) = 0.85 ± 0.07(stat) ± 0.16(syst) MeV a...
Observational transition systems (OTSs) are state machines that can be described as behavioral specifications in CafeOBJ, an algebraic specification language and processor. The OTS/CafeOBJ method uses OTSs and CafeOBJ for systems specification and verification. Simultaneous induction is intensively used to prove that an OTS enjoys invariants in the method. To prove that two state predicates p a...
Using a 4.19 fb−1 data sample collected with the CLEO II detector at the Cornell Electron Storage Ring, we have searched for dipion transitions between pairs of Υ resonances at center of mass energies Ecm = 10.58 GeV and Ecm = 10.52 GeV. We obtain the 90% confidence level upper limits B(Υ(4S) → Υ(2S)π+π−) < 3.9 × 10−4 and B(Υ(4S) → Υ(1S)π+π−) < 1.2 × 10−4. We also observe the transitions Υ(3S) ...
Senyawa kompleks dari garam nikel dengan ligan N,N’ -dietiltiourea ( detu ) perbandingan mol 1:4 berhasil disintesis dan dikarakterisasi metode reaksi langsung refluks. Kompleks Ni- (DR) Ni-detu(R) yang secara berurutan refluks mempunyai titik lebur 159-161°C 114-116°C. Analisis data FT-IR kedua sampel menunjukkan ikatan υ(N-H) Ni-detu berada pada rentang 3233-3235 cm -1 , υ(C-H) 2964-2974 υ(C-...
Recent data from Belle show unusually large partial widths Υ(5S) → Υ(1S)ππ and Υ(5S) → Υ(2S)ππ. The Z(4430) narrow resonance also reported by Belle in ψπ spectrum has the properties expected of a c̄cud̄ charged isovector tetraquark T c̄c . The analogous state T b̄b in the bottom sector might mediate anomalously large cascade decays in the Upsilon system, Υ(mS) → T b̄b π → Υ(nS)ππ, with a tetraquark-...
It is shown that the rates of the decays Υ(1 3 D 1) → η Υ(1S) and Υ(1 3 D 2) → η Υ(1S) should be comparable to and likely exceed that of the recently discussed in the literature two-pion transition Υ(1D) → π π Υ(1S). The reason for this behavior is that the discussed η transitions are enhanced by the contribution of the anomaly in the flavor singlet axial current in QCD.
