El estudio comparó las propiedades sensoriales, fisicoquímicas y la intención de compra de caramelos duros comerciales y saludables (sin azúcar) disponibles en el mercado. Para la evaluación sensorial se seleccionaron diez atributos: intensidad de color y aroma, dulzor, sabor natural y artificial, amargor, retrogusto agradable, fracturabilidad, pegajosidad en dientes y disolución suave, mientras que las variables fisicoquímicas analizadas incluyeron actividad de agua, sólidos solubles, acidez, textura, pH y color. El diseño metodológico combinó un enfoque experimental cuantitativo para los análisis fisicoquímicos y un enfoque sensorial cuantitativo-descriptivo mediante la técnica RATA. Los resultados mostraron que las muestras comerciales obtuvieron puntuaciones significativamente mayores en intención de compra, asociadas a un mayor dulzor, retrogusto persistente, disoluci...

The seismic vulnerability of buildings with considerable age represents a crucial challenge for urban resilience in a historic city like Lima. In this research, a sample of 30 publicly accessible galleries within the Cercado de Lima was evaluated. These structures were built with now-obsolete structural systems and are subject to deteriorated conditions. The FEMA P-154 methodology was applied to conduct rapid visual inspections and to classify the structures according to their level of seismic vulnerability based on the score established by the format. Additionally, a gallery with a critical FEMA score was selected for structural modeling in ETABS using previously scaled historical seismic records, following the guidelines of the E.030 Seismic Design Code. A Schmidt hammer test was also conducted to estimate the concrete strength of the selected building. The results show that more than ...
