Introduction : Radon (Rn) is a chemically inert gas with no odor, color, and taste. It is created from the decay of uranium in the soil and can penetrate the building through the interiors. As a result, Rn can enter the human body with the release of alpha radiation along with airborne dust and cause chronic illnesses such as lung cancer and multiple sclerosis. The Multiple Sclerosis disease, ...
In this paper, we discuss the geometric properties of solution and lower bound estimate of ∆um−1 of the Cauchy problem for a degenerate parabolic equation with periodic source term ut =∆um+ upsint. Our objective is to show that: (1)with continuous variation of time t, the surface ϕ = [u(x,t)]mδq is a complete Riemannian manifold floating in space RN+1and is tangent to the space RN at ∂H0(t); (2...

In this paper we show how the restriction of the complex algebraic cycles to real part of a complex algebraic set îs related to the real algebraic cycles of the real part As a corollary we give examples of smooth submanifolds of a Euchdean space which can not be isotoped to real parts of complex nonsingular subvaneties in the corresponding projective space Algebraic numbers are dense in R. The ...
The radiological hazard of radon gas to occupants in residential environments is from the particulate progeny "'Po, ""Pb, ^Bi and "4P0, rather than ^Rn itself. Attachment to aerosols, plateout and resuspension impacts on the actual progeny airborne concentrations. Plateout rate factors are measured for different air change (ventilation) rates, ACH, in a 0.28 m3 test chamber for interior residen...

In Hilbert space L2(Rn), we prove the equivalence between the mod-ulus of smoothness and the K-functionals constructed by the Sobolev space cor-responding to the Fourier transform. For this purpose, Using a spherical meanoperator.
Sufficient conditions are established for the solvability of the boundary value problem dx(t) dt = p(x, x)(t) + q(x)(t), l(x, x) = c(x) , where p : C(I; Rn)× C(I; Rn) → L(I; Rn), q : C(I; Rn) → L(I; Rn), l : C(I, Rn)× C(I; Rn) → Rn, and cn : C(I, Rn) → Rn are continuous operators, and p(x, ·) and l(x, ·) are linear operators for any fixed x ∈ C(I; Rn). 1. Formulation of the Main Results 1.1. Fo...
