The objective of this paper is experimental studies of the linear absorption coefficient, or mean penetration depth of positrons emitted from Na isotope in different materials. For this purpose we constructed a new experimental setup which allows us to scan the depth implantation profile of positrons. For the studied metals: Mg, Al, the obtained values of mean penetration depth coincide well wi...

Suppression of superconductivity due to the proximity effect between a superconductor and ferromagnet can be partially alleviated when Cooper pair simultaneously samples different directions short-range exchange field. The superconductor's critical temperature, ${T}_{C}$, is therefore expected recover in multidomain state, as opposed single-domain state. Here, we discuss series experiments perf...

in this paper the propagation of harmonic plane waves in a homogeneous anisotropic magneto-piezothermoelastic diffusive body with fractional order derivative is studied. the governing equations for a homogeneous transversely isotropic body in the context of the theory of thermoelasticity with diffusion given by sherief et al. [1] are considered as a special case. it is found that three types of...

Aim: To evaluate the maximum depth of sealer penetration into dentinal tubules at the coronal, middle, and apical third of root canals, following the use of different final irrigation solutions. Materials and methods: Eighty freshly extracted mandibular premolars were selected for the study. After decoronation, instrumentation of samples was done using Protaper universal rotary file system till...
