Intonation and Language Contact: A Case Study of Two Varieties of Peruvian Spanish
… Peruvian Spanish and Quechua intonation using instrumental analysis. Lima and some Cuzco Spanish speakers are shown to coincide with previous descriptions of other varieties of Spanish, depending on the feature considered. More variation is found within Cuzco, including patterns of tonic peak …

Study of a microcomposite metal-doped polyimide adhesive
… The results of mechanical adhesion testing and instrumental analysis of the failed surfaces indicated that the added compounds did in fact preferentially segregate toward the adhered surfaces, but that this segregation decreased the strength of bonds tested in peel. It was concluded that the …

Compatibility and stability of 8% amino acids solution in combination with electrolytes, vitamins and antibiotics
… signs of physical incompatibility. However, instrumental analysis, i.e., U.V. spectroscopy and thin-layer chromatography, suggested, in fact, there may have been chemical interaction of Solu B Forte and MVI once admixed with the amino acids/dextrose solution. Yet, results of thin-layer …
