The effect of the addition alpaca fibers on mechanical response geopolymeric mortars was studied using uniaxial compression tests. were manufactured by mixing mining tailings, fine sand and variable percentages wool fibers. results show a higher degree deformation, up to 6%, for mortar mixtures with amounts fiber in their composition, that is, decrease maximum compressive strength demonstrated ...
A 298 bp region of the Cryptosporidium parvum 18S rDNA and a 390 bp region of the acetyl-CoA synthetase gene were sequenced for a range of human and animal isolates of Cryptosporidium from different geographical areas. A distinct genotype is common to isolates from cattle, sheep and goats and also an alpaca from Peru and is referred to here as the 'calf'-derived Cryptosporidium genotype. Anothe...
The birefringent halfwave plate (HWP) polarization modulator, while new to the CMB field, has been used for decades at shorter wavelengths. The basic idea is simple; a polarized plane wave passing through a HWP will have its polarization orientation rotated by ∆ψ = 2θ, where θ is the angle between the incident polarization and one of the optical crystal axes. Rotating a HWP in front of a linear...
