The highest preva.ence wa. found in Leba.on a.d Syria. with preva.ence dropping in Pa.estine, Jorda., a.d Egypt before increa.ing slightly moving westwa.ds to a.geria.a.d Morocco Phylogenetic a.a.ysis of a.194 nucleotide section of the DWV Lp gene did not identify a.y significa.t phylogenetic resolution a.ong the sa.ples, a.though the sequences did show consistent regiona. clustering, including a. interesting geogra.hic gra.ient from Morocco through North a.rica.to Jorda. a.d Syria. The sequences revea.ed severa. clea. va.ia.ility hotspots in the deduced a.ino a.id sequence, which furthermore showed some pa.terns of regiona. identity. Furthermore, the sequence va.ia.ts from the Middle Ea.t a.d North a.rica.a.pea. more numerous a.d diverse tha. those from Europe.

The objective of the present study is to ca.cula.e photon shielding pa.a.eters for seven polyethylene-ba.ed neutron shielding ma.eria.s. The pa.a.eters include the effective a.omic number(Z_(eff)), the effective electron density(N_(eff)) for photon intera.tion a.d photon energy a.sorption,a.d ga.ma.ra. kerma.coefficient(kc). The ca.cula.ions of Z_(eff)a.e presented a. a.single-va.ued a.d a.e energy dependent. While Z_(eff)va.ues were ca.cula.ed via.simplistic powerla. method, the energy-dependent Z_(eff)for photon intera.tion(Z_(PI-eff)) a.d photon energy a.sorption(Z_(PEa.eff)) a.e obta.ned via.the direct method for energy ra.ges of 1 keV–100 GeV a.d 1 keV–20 Me V, respectively. The kccoefficients a.e ca.cula.ed by summing the contributions of the ma.or pa.tia. photon intera.tions for energy ra.ge of 1 keV–100 MeV. In most ca.es, da.a.a.e presented rela.ive to pure polyethylene to a.low direct compa.ison over a.ra.ge of energy. The results show tha. combina.ion of polyethylene with other elements such a. lithium a.d a.uminum lea.s to neutron shielding ma.eria. with more a.ility to a.sorb neutron a.d cra.s. a.so, the kerma.coefficient first increa.es with Z of the a.ditive element a. low photon energies a.d then converges with pure polyethylene a. energies grea.er tha. 100 keV.

Moreover, the uncerta.nties in the ellipsometric pa.a.eters a. functions of the uncerta.nties of the Fourier coefficients a.e studied. The compa.ison a.ong different configura.ions revea.s tha. the rota.ing compensa.or–a.a.yzer configura.ion corresponds to the minimum error in the ca.cula.ed optica. pa.a.eters.
