On the Dynamics of the Family axd(x − 1) + x

In this paper we consider the dynamics of the real polynomials of degree d + 1 with a fixed point of multiplicity d ≥ 2. Such polynomials are conjugate to fa,d(x) = axd(x−1)+x, a ∈ R{0}, d ∈ N. Our aim is to study the dynamics fa,d in some special cases.

Sex determination by the length ratio of metacarpals and phalanges: X-ray study on Iranian population

Background: In forensic anthropological identification, we usually use body remains. Accurate sex estimation from these remains is very important and needs the knowledge of specific population standards of that area. Sometimes, human remains are damaged by environmental circumstances. So, we must examine single bones for sex estimation. One of the relatively resistant bones to environmental con...

Constraints on the large - x d / u ratio from electron – nucleus scattering at x > 1

Recently the ratio of neutron to proton structure functions F 2 /F p 2 was extracted from a phenomenological correlation between the strength of the nuclear EMC effect and inclusive electron– nucleus cross section ratios at x > 1. Within conventional models of nuclear smearing, this “inmedium correction” (IMC) extraction constrains the size of nuclear effects in the deuteron structure functions...

Effect of low dose X-ray on membrane fluidity of thalassemic red blood cells

Background: Chest X-ray is one of the examinations required for an annual health checkup. The interaction of radiation to the medium produces free radicals, which consequently causes biological changes either structural or properties of the cells. Whether the radiation from Chest X-ray upright technique affects the plasma membrane fluidity of thalassemic red blood cells (RBCs) is still unclear....
