1. Monopropellant droplet decomposition for large activation energies - Liñán Martínez, Amable
By formulating the problem mathematically, it is shown how, in the limit of large activation energies, regions of near equilibrium flow or frozen flow may coexist in the flow field.

2. Gasification effects in the heterogeneous ignition of a condensed fuel by a hot gas - Kindelan Gómez, Manuel; Liñán Martínez, Amable
An analysis is presented to describe the heterogeneous ignition of a condensed fuel suddenly exposed to a hot oxidizing atmosphere.

3. Radiant ignition of a reactive solid with in-depth absorption - Liñán Martínez, Amable; Williams, F.A.
It is shown that as » increases, the structure of the transition stage, which follows the inert heat-conduction stage, passes from a thermal explosion without heat conduction, to a single transient heat-conduction zone with distributed chemical heat release, to a two-zone structure composed of a reactive-diffusive-absorptive zone near the surface and a transient-diffusive zone in the interior.

4. Asymptotic analysis of unsteady diffusion flames for large activation energies - Liñán Martínez, Amable; Crespo Martínez, Antonio
The limit of large activation energy is studied for the process of simultaneous mixing and chemical reaction of two reactants undergoing a one-step irreversible Arrhenius reaction.

5. The vertical plate in laminar free convection: Effects of leading and trailing edges and discontinuous temperature - Messiter, A.F; Liñán Martínez, Amable
The leading-edge region is shown to contribute a secondorder term to the integrated heat transfer.

6. Las marchas del Guadarrama (Villa) - García Pérez, Guillermo; Recio Díaz, María del Mar
Las posibilidades senderistas y montañeras de Guadarrama son poco conocidas.

7. Agés (Término sanjuaneril) - García Pérez, Guillermo
En la última Guía de Soria que he tenido la oportunidadde ojear, puede leerse lo siguiente:"Sábado.

8. Ripartendo dalla colonna (Rev. del libro de R. Gargiani "La colonne. N o u velle histoire de la construction" Lausanne 2008) - Huerta Fernández, Santiago
Una storia della costruzione che mette in luce un rinnovato interesse disciplinare, riconsiderando aspetti tecnici ed evoluzione delle forme architettoniche.

9. Técnicas de perturbaciones singulares en la teoría de reactores catalíticos - Vega de Prada, Jose Manuel; Liñán Martínez, Amable
Se analiza el problema de transporte de calor y masa en partículas porosas de geometrías simétricas (placas, cilindros y esferas) en cuyo interior tiene lugar una reacción catalítica de tipo Arrhenius o Langmuir-Hinshelwood, teniendo en cuenta los efectos de las resistencias al transporte externo de calor y masa.

10. Covadonga, un mito nacionalista católico de origen griego - García Pérez, Guillermo
El Santuario de Covadonga está ubicado en un valle cercano a Cangas de Onís (Asturias),en uno de los accesos más bellos a los Picos de Europa (Cordillera Cantábrica), y parece ser de origen prerromano.

11. Construction History. Review of B. Addis ‘Building: 3000 Years of Design, Engineering and Construction' - Huerta Fernández, Santiago

12. Beitrag zur Geschichte plastischer Berechnungsmethoden im Stahlbau - Kurrer, Karl-Eugen; Huerta Fernández, Santiago
Contribution to the history of plastic analysis methods in steel construction.
