Un Estudio Sobre Conocimientos y Actitudes Hacia la Sexualidad en la Vejez

“…En el marco de programas educativos y con una aplicación de testretest, Hammond (1979) encontró un incremento en el conocimiento y actitudes más permisivas en el personal de residencias geriátricas. White (1982) encontró resultados similares en una muestra de ancianos residentes en institucienes.…”

Maraging Steels—Structure, Properties and Applications

“…Alloying elements used in maraging steels generally lower the M$ temperature; but the effect of any individual element depends on the total composition of the alloy (Owen and Wilson, 1965;Tuffnell and Cairns, 1968;Yeo, 1963;Hammond, 1964;Manenc, Thivellier and Thomas, 1971). Figure 2 shows the effect of solute element content on the Ms and As temperatures in iron-base alloys.…”

Influence of Heat Treatments on Corrosion Behaviour of Alloy 625 Forged Rod

“…In such cases, post-welding heat treatments may be necessary to keep good properties in the heat affected zone of the fenitic steels. But there are few results (11)(12)(13) on the influence of heat treatments on the structure and properties of alloy 625.…”
