Abstract This article shows that for generic choice of Riemannian metric on a compact oriented manifold M dimension four, the tangent planes at any self-intersection $$p \in M$$ p ∈ M prime closed parametrized minimal surface in are not simultaneously c...

In this work, we study the direct-detection constraints of light dark matter in next-to minimal supersymmetric standard model (NMSSM) with non-universal Higgs masses (NUHM), especially correlation between higgsino asymmetry and spin-dependent cross section. Finally, get following conclusions: (i) The section is proportional to square $\tilde{\chi}^0_1$ NMSSM-NUHM. (ii) For highly singlino-domin...

Today, rapid developments are experienced in terms of energy consumption and efficiency air conditioning systems. Among these systems, waste heat renewable sources used absorption cooling Although the initial investment cost this system is high, operating low due to use heat. In study, effect generator, condenser, absorber evaporator temperatures on performance (COP) systems with single-stage L...

The kinetic of photo oxidative decolorization of C.I. Acid yellow 23 (AY23) was investigated in UV/ process. The semi-logarithmic of the concentrations of AY23 versus irradiation time were linear, suggesting pseudo-first order reaction. A simple kinetic model is proposed which confirms pseudo- first order reaction. The results indicate that the apparent reaction rate constant is a function of l...

The implications of the water vapor runaway greenhouse phenomenon for water-rich subNeptunes are developed. In particular, nature post-runaway equilibration process planets that have an extremely high inventory is addressed. Crossing threshold from sub-runaway to super-runaway conditions leads a transition equilibrated states with cold deep liquid oceans and interior ice-X phases hot supercriti...
