      La Curva Medioambiental de Kuznets ha sido una de las hipótesis más debatidas de la Economía Ambiental en las últimas décadas. Según ésta, la relación entre el crecimiento económico y la degradación ambiental, presenta ...
    • Growth and public support to research and imitation: the international connection 

      Pérez Sebastián, Fidel (1999)   Documento de trabajo / Lan gaiak  OpenAccess
      This paper studies technology policy within the context of an R&D-based growth model. We first use cross-country data to document several empirical regularities regarding the relationship between public support to research ...
    • Leaf δ15N as a physiological indicator of the responsiveness of N2-fixing alfalfa plants to elevated CO2, temperature and low water availability 

      Ariz, Idoia Upna; Cruz, Cristina; Neves, Tomé; Irigoyen, J. Juan; García Olaverri, Carmen Upna; Nogués, Salvador; Aparicio Tejo, Pedro María Upna; Aranjuelo Michelena, Iker (Frontiers Media, 2015)   Artículo / Artikulua  OpenAccess
      The natural 15N/14N isotope composition (δ15N) of a tissue is a consequence of its N source and N physiological mechanisms in response to the environment. It could potentially be used as a tracer of N metabolism in plants ...
    • Lipid metabolism, adipocyte depot physiology and utilization of meat animals as experimental models for metabolic research 

      Dodson, Michael V.; Hausman, Gary J.; Guan, LeLuo; Du, Min; Rasmussen, Theodore P.; Poulos, Sylvia P.; Mir, Priya; Bergen, Werner G.; Fernyhough, Melinda E.; McFarland, Douglas C.; Rhoads, Robert P.; Soret Lafraya, Beatriz Upna; Reecy, James M.; Velleman, Sandra G.; Jiang, Zhihua (Ivyspring International Publisher, 2010)   Artículo / Artikulua  OpenAccess
      Meat animals are unique as experimental models for both lipid metabolism and adipocyte studies because of their direct economic value for animal production. This paper discusses the principles that regulate adipogenesis ...
    • Lipogenic enzyme activity in growing Rasa Aragonesa lambs 

      Arana Navarro, Ana Upna; Soret Lafraya, Beatriz Upna; Corroza Muro, Manuel; Mendizábal Aizpuru, José Antonio Upna; Mendizábal Múgica, Francisco Javier; Horcada, Alberto; Eguinoa Ancho, Paola; Purroy Unanua, Antonio Upna (CIHEAM, 1995)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The lipogenic enzyme activity of the following enzymes was studied: Glycerol 3-phosphate dehydrogenase (G3PDH), fatty acids synthetase (FAS), NADP-Malate dehydrogenase (ME) and Glucose 6-phosphate dehydrogenase (G6PDH) ...
    • Long-term mannitol-induced osmotic stress leads to stomatal closure, carbohydrate accumulation and changes in leaf elasticity in Phaselous vulgaris leaves 

      Sassi, Sameh; Aydi, Samir; Hessini, Kamel; González García, Esther Upna; Arrese-Igor Sánchez, César Upna; Abdelly, Chedly (Academic Journals, 2010)   Artículo / Artikulua  OpenAccess
      The effect of long-term osmotic stress was investigated in leaves of two common bean lines, with contrasting tolerance: Flamingo (tolerant) and coco blanc (sensitive). Water relations, organic solute, ion accumulation ...
    • Magnetic anisotropy in isotropic and nanopatterned strongly exchange-coupled nanolayers 

      Vergara Platero, José Upna; Favieres Ruiz, Cristina Upna; Madurga Pérez, Vicente Upna (Springer, 2012)   Artículo / Artikulua  OpenAccess
      In this study, the fabrication of magnetic multilayers with a controlled value of the in-plane uniaxial magnetic anisotropy field in the range of 12 to 72 kA/m was achieved. This fabrication was accomplished by the ...
    • Publicly funded pre-start support for new firms: who demands it and how it affects their employment growth
