    • A Logistic Approach for Kinetics of Isothermal Pyrolysis of Cellulose 

      López-Beceiro, Jorge; Díaz-Díaz, Ana-María; Álvarez García, Ana; Tarrío-Saavedra, Javier; Naya, Salvador; Artiaga, Ramón (MDPI, 2021-03)
      [Abstract] A kinetic model is proposed to fit isothermal thermogravimetric data obtained from cellulose in an inert atmosphere at different temperatures. The method used here to evaluate the model involves two steps: (1) ...

    • Application of the Time–Temperature Superposition Principle to Predict Long-Term Behaviour of an Adhesive for Use in Shipbuilding 

      Souto Silvar, Daniel Abelardo; Álvarez García, Ana; Díaz-Díaz, Ana-María; Rodríguez-Dopico, Francisco J.; López-Beceiro, Jorge (Springer Nature, 2024-02)
      [Abstract]: The use of adhesives in the marine sector is rather limited at the time being, but their use in specific areas of the ship would be an advantage due, among other things, to their low weight and low stress ...

    • Combined effect of seawater and load on methacrylate adhesive 

      Rodríguez-Dopico, Francisco J.; Carbas, R.J.C.; Borges, C.S.P.; Tarrío-Saavedra, Javier; Da Silva, L.F.M.; Álvarez García, Ana (Elsevier, 2023-04)
      [Abstract]: Although the shipbuilding industry is constantly demanding new advanced joining solutions, adhesive technology is not as developed in the marine as compared to other industries. The main reason is the lack ...

    • Comparison by thermal analysis of Joule‑cured versus oven‑cured composites 

      Vázquez, Laura; López-Beceiro, Jorge; Díaz-Díaz, Ana-María; Álvarez García, Ana; Pereira Rodríguez, Mercedes; Artiaga, Ramón (Springer, 2024-03-20)
      [Abstract]: The current technology for curing high-performance composites, such as those used in industries like such as aeronautics and the automotive industry, is based on the use of autoclaves, where the material is ...

    • Ejes del Desarrollo del Espacio Iberoamericano del Conocimiento. Análisis comparativo con el Espacio Europeo de Educación Superior 

      Álvarez García, Begoña; Boedo, Lucía; Álvarez García, Ana (Organización de Estados Iberoamericanos para la Educación, la Ciencia y la Cultura (OEI), 2011)
      [Resumen]: El Espacio Iberoamericano del Conocimiento (eic) ha pasado de ser un ambicioso proyecto a convertirse en una realidad que refleja el enorme interés que tienen los países iberoamericanos por mejorar sus sistemas ...

    • Ensayos experimentales para la obtención del coeficiente hidráulico como un factor relevante en el desarrollo del proyecto de un buque 

      Álvarez García, Ana; Rodríguez-García, JuanDeDios; González López, Primitivo B. (2010-11-15)
      [Resumen]En este artículo se presenta un estudio experimental del comportamiento de un modelo sujeto a la inundación progresiva de sus compartimentos. El estudio consta de varios ensayos mediante los que se inunda uno o ...

    • Kinetics of Thermal Degradation of Cellulose: Analysis Based on Isothermal and Linear Heating Data 

      López-Beceiro, Jorge; Álvarez García, Ana; Sebio-Puñal, Sebio; Zaragoza, Sonia; Álvarez García, Begoña; Díaz-Díaz, Ana-María; Janeiro Arocas, Julia M.; Artiaga, Ramón (NC State University, 2016-05-16)
      [Abstarct]: In spite of the many studies performed, there is not yet a kinetic model to predict the thermal degradation of cellulose in isothermal and non-isothermal conditions for the full extent of conversion. A model ...

      Álvarez García, Ana (2014)
      Las obras a realizar consisten en la ampliación y mejora de la seguridad vial en la vía DP 5810, para ello, se procederá a la ampliación de la plataforma con el objeto de obtener una calzada de 6 m. de ancho, acera de 2 ...

    • The Complexity of Lignin Thermal Degradation in the Isothermal Context 

      López-Beceiro, Jorge; Díaz-Díaz, Ana-María; Álvarez García, Ana; Tarrío-Saavedra, Javier; Naya, Salvador; Artiaga, Ramón (MDPI, 2021-07)
      [Abstract] Thermal degradation of lignin in nitrogen atmosphere is evaluated by linear heating and isothermal tests. While linear heating suggests that thermal decomposition in the 200–400 °C range mainly consists of a ...

    • The effect of marine ageing on the mechanical properties of a structural adhesive 

      Souto Silvar, Daniel Abelardo; Álvarez García, Ana; Díaz-Díaz, Ana-María; Rodríguez-Dopico, Francisco J.; López-Beceiro, Jorge (Springer, 2023)
      [Abstract] The aim of this work is to study the behaviour of a structural adhesive in an aggressive setting such as the marine environment. For this purpose, an ageing procedure is carried out under marine environmental ...
